Description

Drug feeder and drug dispensing device {DRUG FEEDER AND DRUG DISPENSING DEVICE}

The present invention relates to a drug feeder for weighing and taking out a drug in a predetermined amount. The drug feeder of the present invention is suitably used as a device for supplying powdered drugs to a powdered drug dispensing device for dispensing powdered drugs. Further, the drug feeder of the present invention is suitable as a device incorporated in a powdered drug distribution device having a function of dispensing powdered drugs by the powdered drug dispensing device and individually packaging them.

Further, the present invention relates to a drug dispensing device incorporating a drug feeder.

In recent years, in large hospitals and large-scale pharmacies, a powdered drug distribution device and a drug dispensing device having a powdered drug distribution function have been introduced. Here, the powdered drug distribution device is a device for individually packaging powdered drugs, etc. for one dose. If a powdered drug distribution device is used, most of the work of packing powdered drugs, etc. per dose can be automated.

The powdered drug distribution device 200 disclosed in Patent Document 1 is a device for individually packaging a powdered drug for each dose, and as shown in FIG. 49, a drug supply device 201, a powdered drug dispensing device 202, and a drug packaging therein It has a device 203.

The drug supply device 201 disclosed in Patent Document 1 is constituted by an injection hopper 205 and a powder feeder 206 as shown in FIGS. 49 and 50.

As shown in FIG. 50, the powder feeder 206 is provided with two piezoelectric elements 207 and 208 under the trough 210 to vibrate the trough 210.

The powdered medicine dispensing device 202 is constituted by a dispensing dish 212 and a scraping device 215 as shown in FIG. 49. The distribution plate 212 has an arc shape in cross section, and has an annular groove 216 in plan view. The distribution plate 212 is rotated at a constant speed by the motor 219.

The scraping device 215 has a disk 217 that moves up and down and rotates, and a scraping plate 218 is provided on the disk 217.

As shown in FIG. 49, the drug packaging device 203 is constituted by a packaging hopper 220 and a packaging device 221.

Next, the procedure in the case of distributing the powdered drug using the powdered drug distribution device 200 will be described.

The work of distributing the powdered drug is performed by a pharmacist operating the powdered drug distribution device 200 according to a doctor's prescription. In other words, the pharmacist checks the doctor's prescription and takes out a medicine bottle containing the prescribed powder from the medicine shelf (not shown). Then, using a balance such as a balance, the total weight of the prescribed powdered medicine is measured.

That is, if it is a powdered drug that is taken three times a day, 1.0g is prescribed per time, and when a drug for 20 days is prescribed, (1.0 × 3 × 20 = 60) g of the powdered drug is taken out. More specifically, put the container on the scale, subtract the packaging weight, take the powdered medicine from the vial using a medicine spoon, put the powdered medicine in the container on the scale, and weigh 60g of the powdered medicine.

Then, 60 g of the improved powdered medicine is put into the input hopper 205 of the medicine supply device 201.

At the same time, the piezoelectric elements 207 and 208 (FIG. 50) of the powder feeder 206 are energized to vibrate the trough 210, and the distribution plate 212 is rotated about 20 to 30 rotations per minute.

The powdered medicine put into the input hopper 205 falls from the opening of the lower end of the input hopper 205 to the trough 210 of the powder feeder 206. And by vibrating the trough 210, the powdered medicine slowly moves to the tip side and is rectified. In addition, while moving on the trough 210, rectification proceeds so that the flow of the drug is in a laminar flow state. That is, the distribution of the drug in the cross section in the direction orthogonal to the flow becomes constant, and the distance through which the drug is advancing per unit time is also constant. As a result, 60 g of the powdered medicine is uniformly dispersed, and slowly moves toward the tip end at a constant speed per hour.

And eventually, the powdered medicine moving the head reaches the tip of the trough 210, and the powdered medicine moving the head falls from the tip of the trough 210 to the groove 216 of the distribution plate 212. In addition, the powdered medicine that follows is dropped onto the distribution plate 212 by a certain amount per hour. And eventually, the powdered medicine of the last tail falls to the distribution plate 212, and all the powdered medicine of 60g enters the groove 216.

On the other hand, since the distribution dish 212 rotates at a predetermined speed, the powdered medicine falling from the trough 210 is evenly distributed in the grooves 216 of the distribution dish 212.

That is, by the powder feeder 206, the powdered medicine drops little by little to the distribution plate 212, and the distribution plate 212 rotates at a constant speed, so that the powdered medicine is evenly distributed in the grooves 216 of the distribution plate 212. do.

When the dropping of the powdered medicine on the distribution dish 212 is finished, the rotation of the distribution dish 212 is stopped once. And after that, the disk 217 of the scraping device 215 is dropped into the groove 216 of the distribution plate 212. In addition, after that, the distribution plate 212 is rotated by an angle according to the number of distributions. To explain the above-described example, since 60 g of powdered medicine is distributed in 60 packets, the dispensing dish 212 is rotated by (60/360)°, and the powdered drug is placed on the front side of the disk 217 by an amount of (60/360) Collect on Then, the disk 217 is rotated, and the powdered medicine for (60/360)° is scraped out of the distribution plate 212 by the scraping plate 218, and put into the packaging hopper 220. The powdered medicine dropped from the packaging hopper 220 is packaged by the packaging device 221.

Japanese Patent Laid-Open No. 2000-85703

If the powdered drug distribution device 200 disclosed in Patent Document 1 is used, most of the work of packaging the powdered drug for each dose can be automated.

However, in the conventional powdered drug distribution device 200, a process inevitable to depend on human hands remains, and it is difficult to say that it is a device capable of completely automating the distribution of powdered drugs.

That is, in the powdered medicine distribution apparatus 200 of the prior art, it is indispensable for a pharmacist to take out a medicine bottle containing a desired powdered medicine from a medicine shelf, and measure a predetermined amount of powdered medicine from the medicine bottle.

Accordingly, it is an object of the present invention to develop a drug feeder capable of more highly automating the operation of weighing powdered drugs, paying attention to the above-described problems of the prior art.

A form for solving the above problems is a drug feeder configured by a drug container and a main body device, the drug container is detachable from the main body device, and the drug container has a drug discharge unit for discharging the drug, The main body device has a shaking table, a vibrating means for vibrating the shaking table, a container holding means for temporarily fixing the medicine container to the shaking table, and a weight measuring means for directly or indirectly measuring the weight of the medicine container. It is characterized by being loaded on a shaking table, fixing the medicine container to the shaking table by the container holding means, vibrating the shaking table to discharge a small amount of the medicine from the medicine discharging part, and detecting the discharge of the medicine by the weight measuring means. It is a drug feeder.

In the medicine feeder of this embodiment, the medicine container is fixed to the shaking table, and the medicine container is brought into direct contact with the shaking table. By vibrating the shaking table in this state, the entire or part of the medicine container can be vibrated. Thereby, the medicine in the medicine container slowly moves toward the medicine discharge part, and the medicine is rectified, the flow becomes laminar, and discharged from the medicine discharge part.

In addition, since the drug feeder of the present invention is equipped with a weight measuring means, it is possible to detect the amount of discharge of the drug, and thus, it is possible to automate the operation of weighing powdered drugs or the like.

It is preferable that the medicine feeder is provided with a plurality of contact sensors for detecting whether or not the medicine container is in contact with the shaking table.

In the medicine feeder of this embodiment, since a plurality of contact sensors for detecting whether or not the medicine container is in contact with the shaking table are provided, the attitude of the medicine container with respect to the shaking table can be confirmed. Therefore, the drug feeder of the present invention can accommodate fluctuations in the posture of the drug container with respect to the shaking table within a certain range.

That is, since the medicine feeder of this embodiment makes the medicine container vibrate by bringing the medicine container into direct contact with the shaking table and vibrating the shaking table to move the medicine, the posture of the medicine container must be within a certain allowable range.

For example, in order to discharge a certain amount of drugs per unit time from the drug container by vibration, the drug container is preferably in a horizontal position. For example, assuming that the medicine container is attached to the shaking table with the medicine discharge part side of the medicine container inclined upward, the medicine is difficult to move to the medicine discharge part side even when vibration is applied.

Further, for example, if the axis of the drug container and the center line of the shaking table are shifted or intersected, when the drug is moved by vibration, the drug does not enter a laminar flow state, but becomes a turbulent state. In other words, the direction in which the shaking table intends to move the medicine and the direction of the flow path for powdered medicine or the like regulated by the peripheral wall of the medicine container are different, and the distribution of the medicine in the cross section crossing in the flow direction fluctuates.

On the other hand, in this embodiment, since the variation of the posture of the medicine container with respect to the shaking table can be accommodated within a certain range, the distribution of the medicine in the cross section intersecting in the flow direction becomes uniform. Therefore, according to the present invention, the movement of the drug is easily rectified, and the laminar flow state is apt to occur. Therefore, according to the drug feeder of this embodiment, the deviation of the amount of discharge per unit time is small.

As for the drug feeder, it is preferable that the drug container is partially or entirely magnetic, and the container holding means has a magnet.

It is preferable that the magnet is an electromagnet.

In this embodiment, an electromagnet is employed as the container holding means. Therefore, the medicine container can be adsorbed and held on the shaking table simply by energizing the electromagnet. In addition, when energization to the electromagnet is stopped, the medicine container can be removed from the shaking table.

The magnet is installed on the shaking table, and there is an elastic member between the shaking table and the magnet. When the medicine container is adsorbed by the magnet, the magnet moves relative to the shaking table by the magnet's adsorption force, and the magnet and the medicine container, the shaking table and the medicine container It is preferable to contact.

It is preferable that the magnet is an electromagnet.

In the drug feeder of the present invention, when the drug container is adsorbed on the electromagnet or the like, the electromagnet or the like moves relative to the shaking table due to the adsorption force of the electromagnet or the like, and the electromagnet and the like, and the drug container and the shaking table and the drug container can contact. Therefore, in the medicine feeder of the present invention, the adhesion between the shaking table and the medicine container is high, and the vibration of the shaking table can be accurately transmitted to the medicine container.

The medicine container is partially or entirely magnetic, and the container holding means has a permanent magnet and an electromagnet. It is recommended that the drug feeder is configured to release the fixation of the drug container to the shaking table by generating it.

In the medicine feeder of this embodiment, the container holding means has a permanent magnet and an electromagnet, and fixes the medicine container to the shaking table at least by the magnetic force of the permanent magnet. Therefore, when the medicine container is attached to the main body device, the amount of energization to the electromagnet is small. For example, in the case of employing a configuration in which the medicine container is fixed to the shaking table only by the magnetic force of the permanent magnet, it is not necessary to energize the electromagnet while the medicine container is fixed to the shaking table. Therefore, the electromagnet does not generate heat, and the drug in the drug container is not heated. Moreover, since it is not necessary to energize the electromagnet while the medicine container is fixed to the shaking table, power consumption is small. Therefore, even in the entire drug feeder, power consumption is small and heat generation is small, so it is difficult to affect the drug.

It is preferable that the medicine feeder is provided with a cooling means for cooling the main body device.

The drug feeder has a vibration isolator, and there is a vibration isolating member between the vibration isolator and the vibration isolator, and the weight measuring means detects the total weight of the vibration isolator, and the discharge of the drug is measured by a change in the detected weight of the weight measurement means. It is preferable if it is detected.

In the drug feeder of this embodiment, the weight measuring means detects the total weight of the vibration isolator. In addition, the shaking table is vibrated by the vibrating means, but since there is a vibration isolating member between the vibrating means and the vibration isolating table, the vibration of the vibrating means is difficult to be transmitted to the vibration isolating table.

In the drug feeder of this embodiment, as described above, the total weight of the vibration isolator is detected by the weight measuring means, so that the weight measuring means is less susceptible to vibrations, so that the weight of the drug container or the like can be accurately measured.

The intermediate stage and the vibration isolator for supporting the intermediate stage via a vibration isolating member, the vibration means, the shaking table and the container holding means are mounted on the intermediate stage, and the weight measuring means detects the total weight of the vibration isolator. It is preferable that it is a drug feeder that detects the discharge amount of the drug according to the change of the detected weight of the weight measuring means.

Also for the drug feeder of this embodiment, the weight measuring means detects the total weight of the vibration isolator. That is, the weight measuring means measures all the weights of the middle stage, the vibration-proof member, the vibrating means, and the container holding means, in addition to the shaking table and the medicine container on the shaking table.

Further, the shaking table is vibrated by the vibrating means, but all the vibrating members are mounted on the intermediate stage, and the vibration isolator supports the intermediate stage via the vibration isolating member, so that vibrations from the intermediate stage and the like are difficult to be transmitted to the vibration isolator.

In the drug feeder of this embodiment, as described above, the total weight of the vibration isolator is detected by the weight measuring means, so that the weight measuring means is less susceptible to vibrations, so that the weight of the drug container or the like can be accurately measured.

The drug container has a drug reservoir for storing a drug, and has a constriction opening and a lead-out passage between the drug reservoir and the drug discharge part, and the drug container is loaded on a shaking table to vibrate the drug container, and the drug reservoir It is preferable that it is a drug feeder that discharges the drug from the constriction opening into the lead-out passage, moves the medicine inside the lead-out passage toward the drug discharge portion, and drops the drug from the drug discharge portion.

It can be said that the drug feeder of this embodiment fulfills the role of the hopper 205 and the trough 210 in the drug feeder of the prior art.

That is, the drug container employed in the present embodiment has a drug storage portion for storing a drug, and a constriction opening is provided between the drug storage portion and the drug discharge portion. As a result, the flow rate of the drug moving toward the drug discharge unit by vibration is regulated at the constriction opening, thereby creating an opportunity for laminar flow.

That is, the powdered medicine or the like in the drug container is randomly incorporated in the drug reservoir, and it can be said that it is in an irregular state in the drug reservoir. In addition, the drug container is vibrated, and the drug inside is about to move toward the drug discharge unit, but the drug is randomly embedded as described above, and the movement of the drug is turbulent.

The drug moves to the constriction opening, but in the meantime, the drug is vibrated and changes from a random state to a state oriented in one direction. In addition, since the amount of medicine passed per unit time is regulated when passing through the constriction opening, the pulsation of the flow of the medicine is suppressed, and the flow of the medicine is rectified.

Then, powdered medicine or the like discharged from the constriction opening proceeds to the lead-out passage. The powdered medicine or the like is rectified while the lead-out passage is further rectified to proceed to laminar flow, and in a highly laminarized state, falls from the drug discharge unit.

A drug feeder in which a rectifying member is installed in the drug container, the drug container is loaded on a shaking table, and the drug container is vibrated to move the drug in the drug container toward the drug discharge unit, and when moving, part or all of the drug passes through the rectifying member. It is preferable to be.

Since the rectifying member is provided in the drug feeder of this embodiment, the flow of the drug can be uniform.

It is preferable that the above-described rectifying member is replaceable.

In the drug feeder of this embodiment, the rectifying member can be changed according to the properties of the drug.

A coil-shaped member is installed in the drug container, the drug container is loaded on a shaking table, and the drug container is vibrated to move the drug in the drug container toward the drug discharge unit, and when moving, part or all of the drug crosses the coiled member. It is preferable that it is a drug feeder that is fed.

In the drug feeder of the present invention, a coil-shaped member functions as a rectifying member. In addition, it can disintegrate a lump of powdered medicine and return it to its original powder form.

It is preferable that the drug feeder is provided with a desiccant container in a drug container, and a desiccant is disposed in the desiccant container.

According to the drug feeder of the present embodiment, the drug is prevented from getting moisture, and the drug can be discharged smoothly.

And, it is preferable that it is a medicine feeder with a metering function that stops vibration of the shaking table when the current weight, which is the current weight of the medicine container, coincides with or approximately coincides with a value obtained by subtracting the target discharge amount from the original weight.

In addition to the means of measuring the weight of the drug container, it does not matter whether the weighing of the drug container is direct or indirect. That is, only the weight of the drug container may be measured directly, or the weight including devices such as a shaking table may be measured.

In the drug feeder of the present invention, when the original weight, which is the weight of the drug container before discharging the drug, and the current weight, which is the current weight of the drug container, are utilized, and the current weight matches the value minus the target discharge amount from the original weight Stop vibration of the shaking table. Alternatively, in consideration of the weight of the drug during the fall, the current weight is slightly less than the value obtained by subtracting the target discharge amount from the original weight, and the vibration of the shaking table is stopped when approximately equal. Therefore, after the target amount of the medicine is discharged, the vibration of the shaking table is stopped, and the discharge of the medicine is stopped.

It is preferable that the medicine feeder can change the vibration pattern of the shaking table.

The drug feeder of the present embodiment can vibrate the shaking table in an appropriate vibration pattern according to the properties of the drug or the total amount of discharge.

When the medicine feeder vibrates the shaking table and discharges a predetermined amount of medicine in small quantities from the medicine discharge unit, it is preferable that the vibration pattern at the beginning of the discharge and the vibration pattern after that are different from each other.

According to this aspect, in the process of discharging the drug, the vibration pattern can be changed at the beginning of discharging and when the discharging condition is in a stable state. Therefore, the drug can be stably discharged.

The drug feeder of this type has multiple types of vibration patterns at the beginning of discharging when discharging a predetermined amount of drugs from the drug discharging unit by vibrating the shaking table, and according to the type of drug and/or total discharge, It is preferable if the vibration pattern is changed.

In the medicine feeder, the medicine container may have an opening on its upper surface side based on the posture attached to the main body device, and the medicine can be injected into the medicine container from the opening.

The drug feeder of this embodiment is suitable for use in distributing drugs with a low frequency of prescription. Further, the drug feeder of the present embodiment is also suitable for use in distributing drugs that are not suitable to be stored in a drug container.

That is, the protrusion 16 is disposed vertically downward at a position farthest from the drug discharge unit 8.

The iron plate portion 6 is a steel plate containing a magnetic component such as ferrite. The iron plate portion 6 is an outer peripheral portion of the container body 5 and is attached to the lower surface 12 of the peripheral wall.

The rectifying member 7 is a comb-shaped plate (not shown in Figs. 1, 2, and 3). The rectifying member 7 is inside the container body 5, and a void (constriction opening 13) is formed only between the lower surface 12 side of the peripheral wall. The rectifying member 7 is inclined so that the end of the constricting opening 13 side faces the inside of the container body 5 (bottom 10 side).

The rectifying member 7 is detachable from the container body 5. In addition, the illustrated rectifying member 7 is merely an example and can be changed according to the properties of the drug.

In this embodiment, the interior of the container main body 5 is partitioned by the rectifying member 7, and the bottom surface 10 side functions as the powder medicine storage part 17 with the rectifying member 7 as a boundary. Further, the area on the side of the drug discharge part 8 functions as the lead-out passage part 18 with the rectifying member 7 on the lower surface of the peripheral wall 12 as a boundary.

Next, the main body device 3 will be described.

The main body device 3, as shown in Figs. 1 to 3, is a shaking table 20, vibrating means 21a, 21b, intermediate stage 22, vibration isolating table 23, weight measuring means 25, and a foundation member from above, as shown in Figs. It is composed by (26).

Hereinafter, it demonstrates sequentially. The shaking table 20 is a block-type mounting table, and the electromagnets 30a and 30b are embedded therein. That is, in the shaking table 20, magnet attachment holes 28a, 28b are provided, and electromagnets 30a, 30b are incorporated in the magnet attachment holes 28a, 28b.

Further, the electromagnets 30a and 30b are fixed to the bottoms of the magnet attachment holes 28a and 28b via the elastic bodies 32a and 32b. Therefore, the electromagnets 30a and 30b have a slight degree of freedom with respect to the shaking table 20.

The suction portions 31a and 31b (the tip of the iron core) of the electromagnets 30a and 30b are positioned lower than the upper surface of the shaking table 20 as shown in FIG. 1.

In addition, contact sensors 33a, b, c, and d are provided on both outer sides of the electromagnets 30a and 30b and at four corners of the shaking table 20. The contact sensors 33a, b, c, d are specifically electrodes.

Further, a vibration detection sensor 35 is attached to one side of the shaking table 20.

The vibrating means 21a and 21b are piezoelectric elements and have a plate shape.

The intermediate stand 22 and the vibration isolator 23 have a complex shape as described later in practice, but they are only a stand in terms of kinematics, and in Figs. 1 to 3, they are simply shown in a flat plate shape. .

The weight measuring means 25 is a known load cell, has an upper mounting surface 36 and a lower mounting surface 37, and both are at offset positions.

The base member 26 also has a complicated shape as will be described later in practice, but is only a large kinematically, and in Figs. 1 to 3, it is simply shown in a flat plate shape.

Next, the positional relationship of each constituent member of the main body device 3 will be described. In the main body device 3, as shown in Figs. 1 to 3, holding means 21a and 21b are provided between the shaking table 20 and the intermediate table 22. That is, the shaking table 20 and the intermediate table 22 are opposed to each other as shown in FIG. 1, and are connected by means 21a between one end of the shaking table 20 and one end of the intermediate table 22. Further, the other end of the shaking table 20 and the other end of the intermediate table 22 are connected by means of a holding means 21b.

In this embodiment, the member connecting between the shaking table 20 and the intermediate table 22 is no other than the above-described vibrating means 21a and 21b. Therefore, the shaking table 20 has a structure supported by the intermediate table 22 in the hollow by the vibrating means 21a and 21b.

Further, a vibration isolator 23 is disposed under the intermediate stand 22, and a vibration isolator 40 is interposed between the intermediate stand 22 and the vibration isolator 23. The vibration isolating member 40 is a member that has both a vibration isolating function and a vibration isolating function, and a spring 38 and a vibration isolating rubber (not shown) are combined.

In this embodiment, the member connecting between the intermediate table 22 and the vibration isolator 23 is no other than the vibration isolating member 40 described above. Therefore, the intermediate stand 22 has a structure supported by the vibration isolating member 40 hollow from the vibration isolating table 23.

Further, a weight measuring means 25 is disposed under the vibration isolator 23, and a foundation member 26 is disposed under the vibration isolator 23.

In the weight measuring means 25, the upper mounting surface 36 is connected to the lower surface of the vibration isolator 23, and the lower mounting surface 37 of the weight measuring means 25 is attached to the base member 26.

As described above, since the upper mounting surface 36 and the lower mounting surface 37 are in an offset position, the middle part of the weight measuring means 25 is a cantilever-supported structure with respect to the base member 26. And the vibration isolator 23 is supported at the free end side.

In this embodiment, the member connecting between the vibration isolation table 23 and the base member 26 is no other than the weight measuring means 25 described above. Therefore, the vibration isolator 23 has a structure supported by the weight measuring means 25 from the base member 26 in the hollow.

Further, the base member 26 is provided in the vicinity of the dispensing dish 212 of the powdered medicine dispensing device 202 via the vibration-proof member 41.

Since the base member 26 is a base supporting the entire body device 3 of the drug feeder 1, the body device 3 is installed in the vicinity of the dispensing plate 212 of the powdered drug dispensing device 202 It will be.

In the medicine feeder 1 of the present embodiment, as described above, the vibration table 20 is supported in the hollow by the vibration means 21a, 21b, so that the vibration means 21a, 21b are vibrated. If so, this vibration is conducted to the shaking table 20 so that the shaking table 20 vibrates.

Further, in the present embodiment, the shaking table 20, the vibrating means 21a and 21b, the intermediate table 22, and the weights of the accessories are all supported by the vibration isolator 23. In addition, the total weight of the vibration isolator 23 is supported by the upper mounting surface 36 of the weight measuring means 25. Therefore, on the upper mounting surface 36 of the weight measuring means 25, all the weights of the member above the weight measuring means 25 are placed on the mechanism. Therefore, the weight measuring means 25 measures all the weights of the member above the weight measuring means 25. Therefore, in this embodiment, when the medicine container 2 is loaded on the shaking table 20, the weight of the medicine container 2 is measured indirectly.

In addition, as described above, the shaking table 20 and the vibrating means (21a, 21b) generate vibration, but the members that generate the vibration are all mounted on the intermediate stage 22, and the intermediate stage 22 and the vibration isolator Since the vibration isolating member 40 is interposed between (23), the vibration of the shaking table 20 and the vibrating means 21a, 21b is hardly transmitted to the vibration isolating table 23.

In the present embodiment, since the weight measuring means 25 is connected to the vibration isolator 23, the weight measuring means 25 has the influence of the vibration of the shaking table 20 and the vibrating means 21a, 21b. It is difficult to receive, and accurate weight can be detected.

That is, in this embodiment, since the vibration isolating member 40 is provided between the vibration isolating means 21a and 21b and the vibration isolating table 23, the weight measuring means 25 is less susceptible to vibration.

In addition, the present embodiment is provided with the intermediate table 22, the vibration isolator 23 for supporting the intermediate table 22 through the vibration isolating member 40, and means (21a, 21b) and the shaking table having the intermediate table 22 Since (20) is loaded, the weight measuring means 25 is less susceptible to vibration.

The drug feeder 1 of the present embodiment is constituted by the drug container 2 and the body device 3 as described above, but usually both are separate, and both are combined when distributing the powdered drug. It constitutes the medicine feeder (1).

That is, the main body device 3 of the drug feeder 1 is fixed in the vicinity of the distribution plate 212 of the powdered drug dispensing device 202 as described above.

On the other hand, the drug container 2 is loaded and stored on a container shelf (not shown) as shown in FIG. 1. That is, the medicine container 2 is filled with a predetermined powdered medicine, and is mounted on a container shelf (not shown) in a vertical posture or an oblique posture (not shown) as shown in Fig. 1, for example.

The drug feeder 1 of the present embodiment constitutes a part of the powder drug distribution device (or the overall shape of the drug dispensing device is not shown) as described above, and as shown in FIG. 1, the powder drug distribution device 202 It is provided in the vicinity of the distribution plate 212. In addition, as an apparatus constituting the powdered drug distribution device, there is a robot 43 (container moving means) that transports the drug container 2. The robot 43 has an X-Y table (not shown) and a hand 45 that holds the medicine container 2.

Further, the powdered medicine distribution device (not shown in the overall shape) includes a prescription reading unit 46 for reading a prescription, and a control device 47 for controlling the operation of each device.

The prescription reading means 46 is a device that reads the drug name, prescription amount, and other contents of the prescription drug described in the prescription.

Next, the function of the drug feeder 1 of the present embodiment will be described. Further, since the drug feeder 1 constitutes a part of the powdered drug distribution device (the overall shape is not shown), the operation of the drug feeder 1 will be described including the operation of the entire powdered drug distribution device.

In this embodiment, as described above, the drug container 2 and the main body device 3 are separate, and both are combined to form the drug feeder 1 when distributing the powdered drug.

That is, in this embodiment, the medicine container 2 is stored in a vertical posture or an oblique posture, and the powdered medicine is stored in the powdered medicine storage part 17. In this embodiment, as shown in FIG. 1, the medicine container 2 is moved by holding the medicine container 2 with the hand 45 of the robot 43, and the main body device 3 as shown in FIG. To load.

More specifically, as shown in FIG. 2, the posture is changed while the medicine container 2 is moved. That is, the medicine container 2 is moved in the vicinity of the main body device 3, and the medicine container 2 is laid down in a horizontal position, and it is placed on the shaking table 20. In this case, as shown in FIG. 2, the lower surface of the peripheral wall 12 is set to be down. That is, the iron plate part 6 of the medicine container 2 puts the medicine container 2 on the shaking table 20 in a posture facing the shaking table 20.

And it is energized to the electromagnets (30a, 30b) built in the shaking table (20). As a result, magnetic force is generated in the electromagnets 30a and 30b, and the iron plate portion 6 of the medicine container 2 is adsorbed by the suction portions 31a and 31b (the tip of the iron core) on the shaking table 20 side.

In addition, in this embodiment, the electromagnets 30a and 30b are fixed to the bottom of the magnet attachment holes 28a and 28b via the elastic bodies 32a and 32b, and the electromagnets 30a and 30b are the shaking tables 20 2, the electromagnets 30a, 30b slightly move toward the iron plate portion 6, and the adsorption portions 31a, 31b to the iron plate portion 6 of the medicine container 2 ) Is attached.

Further, due to the elasticity of the iron plate portion 6 of the medicine container 2 and the shaking table 20 itself, they are slightly deformed and fit.

As a result, the iron plate portion 6 of the medicine container 2 comes into close contact with the surface of the shaking table 20 and the electromagnets 30a, 30b.

Subsequently, in the present embodiment, the degree of adhesion between the drug container 2 and the shaking table 20 and the posture of the drug container 2 are confirmed.

Specifically, when the contact sensors 33a, b, c, d provided around the electromagnets 30a, 30b are energized, and there is conduction between the contact sensors 33a, b, c, d, the medicine container 2 It is determined that the degree of close contact between the and shaking table 20 and the posture of the drug container 2 are normal. Conversely, if there is no conduction between the contact sensors 33a, b, c, d, the degree of close contact between the medicine container 2 and the shaking table 20 is insufficient, or the posture of the medicine container 2 is abnormal.

That is, the contact sensors 33a, b, c, d are electrodes exposed on the surface of the shaking table 20. On the other hand, since the iron plate 6 is provided on the outer peripheral portion of the drug container 2 and the lower surface of the peripheral wall 12, the drug container 2 is in close contact with the shaking table 20, and the drug container 2 When the posture is normal, the contact sensors 33a, b, c, d contact the iron plate portion 6, and the contact sensors 33a, b, c, d conduct electricity through the iron plate portion 6 .

Conversely, if there is a problem such as insufficient adhesion between the medicine container 2 and the shaking table 20, one or all of the contact sensors 33a, b, c, d does not contact the iron plate part 6 , The contact sensors 33a, b, c, d are in an insulated state.

When it is confirmed that there is conduction between the respective contact sensors 33a, b, c, and d, the shaking table 20 is vibrated. More specifically, vibration is generated by energizing a current of a constant frequency to the vibrating means 21a and 21b, and the shaking table 20 is vibrated by this vibration. Further, the amplitude of the shaking table 20 is monitored by the vibration detection sensor 35, and the current frequency input to the vibrating means 21a and 21b is changed as the amplitude increases.

In addition, the dispensing dish 212 of the powdered medicine dispensing device 202 is rotated before and after the start of vibration.

Further, before and after the start of vibration, the weight of the medicine container 2 is measured. The weight of the drug container 2 is obtained by subtracting a predetermined value from the detected weight of the weight measuring means 25. More specifically, the weight of the drug container 2 is obtained by subtracting the weight of the member above the weight measuring means 25 of the main body device 3 from the detected weight of the weight measuring means 25.

That is, in the weight measuring means 25, the shaking table 20, the vibrating means 21a, 21b, the intermediate table 22, and the weights of the accessories are all supported by the vibration isolating table 23, and the weight measuring means 25 ) To measure the weight of the vibration isolator 23, the weight measuring means 25 measures all the weights of the members above the weight measuring means 25.

Therefore, when the medicine container 2 is loaded on the shaking table 20, the value obtained by adding the weight of the medicine container 2 to the weight of the shaking table 20 is detected by the weight measuring means 25. do.

Here, since the weight of the shaking table 20 is known, the weight of the medicine container 2 can be indirectly detected by subtracting the weight of the shaking table 20 by the weight detected by the weight measuring means 25. .

The weight of the medicine container 2 immediately after installation on the shaking table 20 is stored as the original weight G. In addition, the weight of the medicine container 2 is always monitored. That is, the current weight of the drug container 2 is monitored as the current weight g.

When the shaking table 20 starts to vibrate, the medicine container 2 vibrates. Here, in the present embodiment, the medicine container 2 is firmly bonded to the shaking table 20 by the electromagnets 30a and 30b, and the degree of contact with the shaking table 20 is also high, so that the medicine container 2 Vibrates at the same frequency as the shaking table 20. As a result, the powdered medicine stored in the powdered medicine storage part 17 of the medicine container 2 slowly moves toward the medicine discharge part 8 side.

Further, as the shaking table 20 vibrates, the drug container 2 itself also receives a force to move in the forward direction, but in this embodiment, a protrusion 16 is provided at the rear end of the drug container 2, When the protrusion 16 comes into contact with a part of the shaking table 20 or the like, the advance of the drug container 2 itself is prevented. Therefore, the medicine container 2 does not move, and only the powdered medicine inside moves.

Then, the powdered medicine reaches the constricting opening 13 formed by the portion of the rectifying member 7. Since the height of the opening of the constriction opening 13 is limited, the height of the powdered medicine passing through the constriction opening 13 is fixed. That is, the powdered medicine flows through the lower surface 12 of the peripheral wall of the medicine container 2 like a river, but the height from the lower surface of the peripheral wall 12 to the upper part of the powdered medicine is uniform in the width direction.

The powdered medicine that has passed through the constriction opening 13 is discharged to the lead-out passage 18. And the powdered medicine flows through the lead-out passage part 18 like a river flow, and eventually reaches the drug discharge part 8 of the medicine container 2, falls like a waterfall, and the groove 216 of the lower distribution dish 212 ).

The fact that the powdered medicine is falling is confirmed by a decrease in the weight of the medicine container 2. That is, in this embodiment, even while the powdered medicine is falling from the medicine discharge part 8 of the medicine container 2, the current weight of the medicine container 2 is continuously monitored as the current weight g. And the original weight G of the medicine container 2 immediately after installation on the shaking table 20 and the current weight g are compared, and the fall amount H (G minus g) of the powdered medicine is always calculated.

In addition, the vibration intensity of the shaking table 20 is fed back so that the falling amount h of the powdered medicine per unit time becomes constant. That is, when the fall amount h per unit time is too small, the frequency of vibration increases. Conversely, when the amount of fall is too large, the frequency is lowered. Likewise, the magnitude of the amplitude is fed back so that the amount of falling h per unit time becomes constant.

Then, the vibration of the shaking table 20 is stopped at the place where the total falling amount H of the powdered medicine reaches the desired weight.

After that, the rotation of the dispensing dish 212 is stopped, and the dispensing dish 212 is rotated by an angle according to the number of dispensing, similar to the powdered drug distribution device of the prior art, and the powdered drug is dispensed with a scraping device (not shown). It is scraped out of (212) and sent to a drug packaging device (not shown) at the rear end.

Next, an embodiment of an embodiment of the present invention which is closer to practical design will be described. In the drug feeder 50 described below, in order to lower the overall height, the member shape is greatly different from the mechanism diagram shown in Fig. 1, and the assembly relationship of the parts is intertwined, but the basic structure and function of each member are, It is the same as the above-described embodiment. The constituent members of the drug feeder 50 described below basically have all the functions of the drug feeder 1 described above. Therefore, although the shape is different, members that perform the same function are given the same numbers and names. In addition, the description of the member and the like will be mainly described in terms of portions different from those of the above-described embodiment, and the overlapping portions are limited to the outline description.

Similar to the above-described embodiment, the drug feeder 50 of the form close to practical design is constituted by the drug container 2 and the main body device 3 (FIG. 4).

First, the structure of the medicine container 2 will be described. In addition, in this embodiment, six kinds of medicine containers 2A, 2B, 2C, 2D, 2E, 2F are prepared depending on the application.

That is, the drug container 2A of the first aspect is of a type without a lid on the drug discharge portion 8 as shown in FIG. 5. The drug container 2B of the second aspect is a two-sided open type as shown in Fig. 10, and when the drug discharging portion 8 has no cover and is in a horizontal position, a portion corresponding to the ceiling surface is largely opened. The medicine container 2C of the 3rd aspect is a closed type, as shown in FIG. 12, and is a type with a lid. The drug container 2D of the fourth aspect is of a closed type as shown in Fig. 34, and is of a type with a lid. As shown in Fig. 43, the drug container 2E of the fifth aspect is of a closed type, a type with a cover, and a type that can be opened and closed because a large cover is provided at a portion corresponding to the ceiling surface.

In order to explain, the medicine container 2A of the first aspect is constituted by the container body 5, the iron plate portion 6, and the rectifying member 7 as shown in FIGS. 5 and 6.

The container body 5 is a vertically elongated container made of resin, and has an end portion in the longitudinal direction as a medicine discharging portion 8.

In the present embodiment, the cross-sectional shape of the container body 5 is hexagonal as shown in FIGS. 5 and 6. That is, there are six peripheral wall surfaces 11 of the container body 5 including the lower surface 12 of the peripheral wall.

In addition, as shown in FIGS. 5 and 6, there is an upper surface 51 of the peripheral wall facing the lower surface of the peripheral wall 12 based on the state in which the container body 5 is horizontally stacked.

Further, as a surface connecting the upper surface 51 of the peripheral wall and the lower surface of the peripheral wall 12, there are left and right vertical peripheral walls 52a and b and left and right inclined peripheral walls 53a and b.

Further, in the present embodiment, the powdered medicine has a structure in which it is easy to collect on the lower surface 12 of the peripheral wall from another peripheral wall.

Also in this embodiment, the protrusion 16 is provided on the outer peripheral surface side of the container main body 5. The position of the protrusion 16 and the like are the same as those of the above-described embodiment, and when the container body 5 is placed in a horizontal position, it protrudes downward.

The iron plate portion 6 is formed into a shape that conforms to the lower surface of the peripheral wall 12 and a part of the left and right inclined peripheral walls 53a and b.

That is, the cross-sectional shape of the iron plate portion 6 is symmetrical, as shown in Fig. 6, and has a planar peripheral wall lower surface contact portion 55, and inclined peripheral wall contact portions 56a and b are on both sides thereof.

There is a certain angle between the lower surface contact portion 55 of the peripheral wall and the inclined peripheral wall contact portions 56a, b, and this angle is the lower surface 12 of the peripheral wall of the container body 5 and the left and right inclined peripheral walls ( It is equivalent to the angle between 53a and b).

The iron plate portion 6 is on the outer peripheral surface side of the container body 5 and is adhered to a portion corresponding to the peripheral wall lower surface 12.

The rectifying member 7 is molded of resin, as shown in Fig. 8, and is provided with a substantially square waste paper plate portion 57, a first comb-shaped portion 58, and a second comb-shaped portion 60.

The first comb-shaped portion 58 extends in an oblique direction from the vicinity of the lower side of the closing plate portion 57, and the free end side is divided into a plurality of portions, thereby exhibiting a comb shape.

The second comb-shaped portion 60 extends obliquely rearward from the rear surface of the closing plate portion 57, and has a plurality of free end sides, thereby exhibiting a comb shape.

The rectifying member 7 is located inside the container body 5 as shown in FIGS. 5 and 7, and the free end side of the comb-shaped portions 58 and 60 is inclined toward the bottom surface 10 side. That is, the comb-shaped portions 58 and 60 of the rectifying member 7 are inclined so that the free end side is inside the container body 5.

7, between the free end of the first comb-shaped portion 58 and the lower surface of the peripheral wall 12 and between the free end of the second comb-shaped portion 60 and the lower surface of the peripheral wall 12 A constriction opening 13 is formed. The first and second comb-shaped portions 58 and 60 are inclined so that the end portion on the side of the constricting opening 13 faces the inside of the container body 5 (the bottom surface 10 side).

Also in this embodiment, the inside of the container main body 5 is partitioned by the rectifying member 7, and the bottom surface 10 side functions as the powder medicine storage part 17 with the rectifying member 7 as a boundary. . Further, the area on the side of the drug discharge part 8 functions as the lead-out passage part 18 with the rectifying member 7 on the lower surface of the peripheral wall 12 as a boundary.

Next, a modified example of the drug container 2 will be described. In the description of each modified example described below, a member common to the above-described drug container 2A or a portion exhibiting a common function is denoted by the same number as B, C, D, E, F, and detailed description. Is omitted.

A second aspect of the drug container 2B will be described with reference to FIGS. 9 and 10. As shown in FIG. 10, the drug container 2B is a two-sided open type, and when the drug discharging portion 8 is not covered and is in a horizontal position, a portion corresponding to the ceiling surface is largely opened. That is, it can be said that the medicine container 2B has the upper side of the medicine container 2A of the above-described first aspect removed. To explain more simply, a portion corresponding to the upper peripheral wall 51 (Fig. 6) is missing from the medicine container 2B.

The medicine container 2B is comprised of the container main body 5B, the iron plate part 6B, and the rectifying member 7B, similarly to the medicine container 2A of the 1st aspect mentioned above.

Then, as shown in Figs. 9 and 10, the side facing the lower surface 12B of the peripheral wall is opened based on the state in which the container body 5B is horizontally stacked.

Also in this embodiment, the protrusion 16B is provided on the outer peripheral surface side of the container main body 5B. The position of the protrusion 16B is the same as in the above-described embodiment, and when the container main body 5B is placed in a horizontal position, it protrudes downward.

The iron plate portion 6B has the same shape as the iron plate portion 6 of the drug container 2A of the first embodiment described above, and is formed in a shape matching the lower surface of the peripheral wall 12B or the like.

The iron plate portion 6B is on the outer peripheral surface side of the container body 5B and is adhered to a portion corresponding to the peripheral wall lower surface 12B.

The rectifying member 7B has its main parts the same as those employed in the drug container 2A of the first form described above, and the waste plate portion 57B, the first comb-shaped portion 58B and the second comb-shaped portion (The second comb-shaped part is not shown in the drawing) is installed. However, the total height of the waste plate portion 57B is lower than that employed in the drug container 2A of the first aspect described above.

Next, a drug container 2C of a third aspect will be described with reference to FIG. 12. The medicine container 2C is of a closed type, and a lid member 120 is provided in the container body 5C.

That is, the medicine container 2C is comprised by the container main body 5C, the iron plate part 6C, and the lid member 120. Moreover, in the medicine container 2C, the rectifying part 7C (FIG. 13) is integrally provided on the rear end side of the lid member 120. As shown in FIG. In addition, the rectifying part 7C has the same function as the rectifying members 7A and 7B described above, but is a part of the lid member 120 as will be described later, and thus is referred to as a rectifying part 7C.

Moreover, the medicine container 2C is provided with the iron plate part 157 for transportation.

The container main body 5C is a vertically elongated container made of resin, and has one end portion in the longitudinal direction as a drug discharging portion 8C. In the present embodiment, the cross-sectional shape of the container body 5C is hexagonal as shown in Figs. 11, 12, and 13. That is, there are six peripheral wall surfaces 11C of the container body 5C including the lower surface 12C of the peripheral wall.

In this embodiment, between the shaking table 20 and the intermediate table 22, the vibrating means 21a and 21b are present, and the shaking table 20 is not supported at a site other than the vibrating means 21a, 21b. not. Therefore, the shaking table 20 has a structure supported by the intermediate table 22 in the hollow by vibrating means 21a and 21b.

Further, a vibration isolator 23 is disposed under the intermediate table 22. To explain the positional relationship between the two, the protrusion 80 provided in the center of the vibration isolator 23 is inserted into the cavity 75 of the intermediate stand 22 as shown in FIGS. 22, 23 and 24. However, the ceiling surface 81 of the protrusion 80 and the inner surface of the cavity 75 of the intermediate stand 22 are not in contact with each other. That is, the intermediate stage 22 and the vibration isolator 23 are intertwined, but kinematically, the structure is the same as that shown in FIG. 1, and the ceiling surface 81 of the protrusion 80 and the cavity 75 of the intermediate stage 22 ) It is not in contact with the inside.

In addition, there are intermediate support portions 83a, b, c, d of the vibration isolator 23 immediately under the four protrusions 77a, b, c, d on the intermediate stand 22, and the vibration isolating member 40 between the two is It is connected to.

The vibration isolating member 40 is a member that has both a vibration isolating function and a vibration isolating function, and as shown in the figure, a spring 38 and a vibration isolating rubber 96 are combined.

That is, in the four protrusions 77a, b, c, d of the intermediate stage 22, a round hole 85 opened at the lower side is formed as shown in FIG. 23, and most of the spring 38 is formed in the intermediate stage ( It is inserted into the round hole 85 of 22).

In this embodiment, the member connecting between the intermediate table 22 and the vibration isolator 23 is no other than the vibration isolating member 40 described above. Therefore, the intermediate stand 22 has a structure supported by the vibration isolating member 40 hollow from the vibration isolating table 23.

As described above, the intermediate stage 22 and the vibration isolator 23 are intertwined, but kinematically, the structure is the same as that shown in FIG. 1, and the intermediate stage 22 is formed by the vibration isolating member 40. ) To the hollow structure.

Further, below the vibration isolator 23, as shown in Figs. 22, 23, and 24, a weight measuring means 25 is arranged, and a foundation member 26 is arranged below the vibration isolator 23.

The weight measuring means 25 is mostly in the protrusion 80 provided in the center of the vibration isolator 23, as shown in FIGS. 22, 24 and 25, and the upper mounting surface 36 of the weight measuring means 25 It is connected to the inner surface of the ceiling surface 81 of the protrusion 80 of this vibration isolation table 23.

On the other hand, the lower mounting surface 37 of the weight measuring means 25 is provided on the base member 26.

As described above, since the upper mounting surface 36 and the lower mounting surface 37 are in an offset position, the middle part of the weight measuring means 25 is a cantilever-supported structure with respect to the base member 26. And the vibration isolator 23 is supported at the free end side.

In the present embodiment, most of the weight measuring means 25 are inserted into the vibration isolator 23 and the intermediate stand 22, and are in a complicated positional relationship, but the kinematically is the same as the structure shown in FIG. , The middle portion of the weight measuring means 25 has a structure that is cantilevered with respect to the base member 26, and supports the vibration isolator 23 at its free end side.

In this embodiment, the member connecting between the vibration isolation table 23 and the base member 26 is no other than the weight measuring means 25 described above. Therefore, the vibration isolator 23 has a structure supported by the weight measuring means 25 from the base member 26 in the hollow.

In addition, in this embodiment, most of the weight measuring means 25 are in the protrusion 80 provided in the center of the vibration isolator 23 as shown in FIGS. 24 and 25, and are located in the center of the vibration isolator 23 Since the provided protrusion 80 is in the cavity 75 of the intermediate stage 22, it can be said that most of the weight measuring means 25 are inserted into the intermediate stage 22 in relation to the height direction.

Therefore, in this embodiment, the influence of the height of the weight measuring means 25 on the overall height of the main body device 3 is small, and the overall height of the main body device 3 is low.

In addition, the base member 26 is attached to the vicinity of the dispensing plate 212 of the powdered medicine dispensing device 202 via the vibration-proof member 41 as in the above-described embodiment.

That is, the four corners of the base member 26 are cut off to form the spring support portions 90a, b, c, d (Fig. 19), and the lower surface of the spring support portions 90a, b, c, d , The base of the powdered medicine distribution device 202, etc. are provided through the vibration-proof member 41. Further, the anti-vibration member 41 is constituted by a spring 84 (FIG. 20) and a vibration-proof rubber (not shown).

Next, the function of the drug feeder 50 of the present embodiment will be described.

The function of the drug feeder 50 is approximately the same as the drug feeder 1 described above, and is energized to the electromagnets 30a, 30b built in the shaking table 20, and the drug containers 2A, 2B, 2C, 2D, 2E) Is fixed to the shaking table 20, and the medicine containers 2A, 2B, 2C, 2D, 2E are vibrated to discharge the powdered medicine. Hereinafter, the case where the medicine container 2C (FIG. 12) is used is demonstrated as an example. That is, the case of using the medicine container 2C of the type with the cover which is the 3rd form is demonstrated as an example.

Also in this embodiment, the medicine container 2C is fixed to the shaking table 20 by the magnetic force of the electromagnets 30a and 30b. Here, the medicine container 2C has a step portion 121 on the side of the medicine discharge portion 8 as shown in FIG. 11, and the lower surface of the peripheral wall 12C has an upper end portion 123 with the step portion 121 as a boundary. ) And the lower part 122 is divided. And the iron plate part 6C is the outer peripheral surface side of the container main body 5C, and is bonded to the part corresponding to the upper end 123 of the peripheral wall lower surface 12C.

Therefore, in this embodiment, as shown in Fig. 11, the upper end 123 of the lower surface 12C of the peripheral wall of the container main body 5C in the medicine container 2C is of the electromagnets 30a, 30b (Fig. 2). It is fixed to the shaking table 20 by magnetic force.

In addition, since the shape of the medicine container 2C and the shape of the shaking table 20 are different from the above-described embodiment, the medicine container 2C has a peculiar behavior.

That is, also in this embodiment, the medicine container 2C is conveyed by a robot hand (not shown) or the like.

When conveyed, the medicine container 2C changes its posture from the original vertical posture to the horizontal posture as shown in Figs. 11 and 26A, and approaches the main body device 3.

At this time, the attitude of the hand 45 is controlled so that the axis line BC of the medicine container 2C and the axis line MC of the main body device 3 coincide as much as possible by the robot 43 of FIG. It is difficult, and, as shown in Fig. 26(b), there are cases where both deviate.

And while the axis line BC of the medicine container 2C and the axis line MC of the main body device 3 are shifted, the medicine container 2C is installed on the shaking table 20, but in this embodiment, the bottom of the medicine container 2C There are inclined peripheral wall contact portions 56aC and 56bC in the iron plate portion 6C provided in the vicinity, and have a substantially tapered shape.

On the other hand, the shaking table 20 is also provided with a frame portion 66 on the loading surface 61 as described above, and has a substantially tapered shape.

Therefore, when the medicine container 2C is installed on the shaking table 20, it is guided by the taper, and the inclined peripheral wall contact portions 56aC and 56bC on the side of the medicine container 2C, and the shaking table 20 as shown in FIG. The inclined surface 68 tends to match.

Moreover, in this embodiment, the protrusion 16C is provided near the rear end part of the medicine container 2C. On the other hand, in the medicine feeder 50 of the present embodiment, a fitting recess 108 is provided between the sensor holding portion 69 of the sensor bracket 70 and the short side side surface 63b of the shaking table 20. Therefore, in this embodiment, when the medicine container 2C is installed on the shaking table 20, the protrusion 16C of the medicine container 2C is fitted with the fitting recess 108 on the side of the main body device 3.

As a result, the posture of the medicine container 2C is corrected, and the axis line BC of the medicine container 2C and the axis line MC of the main body device 3 come close to each other as shown in Fig. 27B. However, the inclined peripheral wall contact portions 56aC and 56bC of the drug container 2C and the inclined surface 68 of the shaking table 20 do not completely coincide, and as shown in Fig. 27A, the inclination of the drug container 2C In some cases, a portion D where the peripheral wall contact portions 56aC and 56bC and the inclined surface 68 of the shaking table 20 do not coincide with each other may occur. In this case, as shown in FIG. 27B, the axis line BC of the medicine container 2C and the axis line MC of the main body device 3 are slightly shifted.

In this state, when the electromagnets 30a and b are energized, the planar peripheral wall lower surface contact portion 55C provided on the peripheral wall lower surface 12C of the medicine container 2C is adsorbed by the electromagnets 30a and b, The lower surface of the peripheral wall contact portion 55C is pulled closer to the side of the shaking table 20, and the lower surface contact portion 55C of the peripheral wall comes into close contact with the mounting surface 61 of the shaking table 20. And the tapered shape of the medicine container 2C and the shaking table 20 coincide with the force applied at that time, and as shown in FIG. 28(b), the axis line BC of the medicine container 2C and the axis line of the main body device 3 MC matches.

Further, since the contact portion 55C on the lower surface of the peripheral wall of the drug container 2C is in close contact with the loading surface 61 of the shaking table 20, the horizontal posture of the drug container 2C is also secured.

In addition, in this embodiment, on the condition that the contact sensors 33a, b, c, d provided at the four corners of the loading surface 61 are connected to each other, the degree of adhesion between the medicine container 2C and the shaking table 20 and It is determined that the posture of the medicine container 2C is normal.

Also in the medicine feeder 50 of this embodiment, after fixing the medicine container 2C to the shaking table 20, the medicine container 2C is vibrated to discharge the powdered medicine, but at this time, the vibration also advances the medicine container 2C. The direction is forceful. However, in the drug feeder 50 of this embodiment, the protrusion 16C of the drug container 2C provided at the rear end of the drug container 2C is fitted with the fitting recess 108 on the side of the main body device 3. Because it is aligned, the medicine container 2C itself does not move in the axial direction.

In addition, in this embodiment, when the medicine in the medicine container 2C advances toward the medicine discharge part 8C side, the medicine is the part of the comb shape 142 of the swash plate part 141 shown in FIG. Passes through the coil 126, crosses the rectifying coil 126 and passes through the gap of the line. As a result, the flow of the drug is smoothed. In addition, even if a lump of the drug is present, the lump is disintegrated when passing through the comb-shaped portion and the rectifying coil 126 and returns to a powdery state.

In the above, the operation of the drug feeder 50 has been described using the case where the drug container 2C of the third form is used as an example, but the same operation is performed even when the drug container 2D of the fourth form is used.

However, if the drug container 2D of the fourth form (FIG. 34) is used instead of the drug container 2C of the third form, there is an effect that the drugs previously filled in the drug container 2D are preferentially discharged.

In the medicine container 2D of the fourth aspect, since the lid member 120D is removed and the medicine is filled therein, the medicine is injected in a vertical position. Therefore, the injected medicine is deposited from the bottom 10D side of the container main body 5D.

On the other hand, when discharging the drug, the drug container 2D is laid down in a horizontal position as shown in FIG. Here, in the drug container 2D of the fourth aspect, inclined portions 181a and b are provided on the inner side of the lower surface of the peripheral wall 12D, and at the inner portion thereof. Therefore, as shown in FIG. 42, the old drug layer 360, which was first put into the drug container 2D and deposited on the bottom surface 10D side of the container body 5D, is below the new drug layer 361. Go back. Therefore, the drugs of the old drug layer 360 are mixed with the drugs of the new drug layer 361 and discharged.

In addition, when the medicine moves by vibration, the medicine in the old medicine layer 360 flows under the new medicine layer 361.

Here, when the drugs of the second floor move together and reach the position of the comb-shaped rectifying member 130D, the upper side of the second floor is at the plate-shaped portion 362 of the comb-shaped rectifying member 130D as shown in FIG. It is scraped up. In particular, since the comb-shaped rectifying member 130D is in an inclined posture as a whole, the upper side of the second floor is scraped and stacked at the plate-shaped portion 362 of the comb-shaped rectifying member 130D, and the bottom surface 10D is shown as an arrow. Is returned to the side. Therefore, the old drug layer 360 moving on the lower layer side is preferentially discharged, and a first-in, first-out flow of the drug in the drug container 2D can be realized.

Next, peripheral devices of the drug feeder 50 will be described.

The drug feeder 50 of the present embodiment constitutes a part of the drug dispensing device 100 having a powder drug distribution function.

The overall structure of the drug dispensing device 100 is, for example, as shown in FIG. 30. The drug dispensing device 100 is functionally divided into a drug shelf area 103, a drug division area 105, and a drug packaging area 106 in the vertical direction.

In the uppermost medicine shelf area 103, a medicine container storage shelf 101 is arranged around it, and a medicine container moving device 102 is provided therein.

The drug shelf area 103 is dehumidified by a dehumidifying device (not shown). In addition, a dust collecting window (not shown) is installed inside the drug shelf area 103, and dust in the drug shelf area 103 is removed. For example, a blowing fan is provided in the medicine shelf area 103, and the air in the medicine shelf area 103 is circulated by the blowing fan. Then, a filter is installed in a certain ventilation path, such as on the intake side of the blowing fan, to remove dust or the like floating in the drug shelf area 103.

The medicine container moving device 102 has a vertical lifting shaft 110, a horizontal moving arm 180, and a hand part 112 that holds the medicine container 2C. The horizontal movement arm 180 has joints 168 and 169 in two places as shown in FIG. 30. The hand part 112 can change the posture of the medicine container 2C. Moreover, in the medicine container moving device 102, the hand part 112 of the electromagnet 170 is adopted. That is, as shown in FIGS. 30 and 31, the electromagnet 170 is installed at the tip of the horizontal movement arm 180.

A powdered drug dispensing device 202 is provided in the drug division area 105. In this embodiment, the powdered medicine dispensing device 202 has two dispensing plates 212. In the powdered medicine dispensing device 202, a plurality of medicine feeders 50 of the present embodiment are provided. In this embodiment, a plurality of drug feeders 50 are provided in each distribution dish 212. In more detail, three drug feeders 50 are installed in each distribution dish 212. Each medicine feeder 50 is provided with respect to each distribution plate 212 in a tangential direction. In addition, the installation angle of the drug feeder 50 to each distribution dish 212 is not limited to the tangential direction, but by installing the drug feeder 50 in a tangential direction to each distribution dish 212, the drug There is an effect of increasing the distribution precision of. Further, when holding the drug container 2C by the drug container moving device 102 and fixing the drug container 2C to the shaking table 20, or when removing the drug container 2C from the shaking table 20, The effect of reducing unnecessary operations of the drug container moving device 102 can be expected.

In the drug packaging area 106, a drug packaging device 203 is incorporated.

Further, the drug dispensing device 100 is provided with a prescription reading means 46 for reading a prescription, and a control device 47 for controlling the operation of each device.

Further, on the outer wall side of the drug packaging area 106, a drug container inlet 151 as shown in FIG. 29 is provided. Inside the medicine container inlet 151, a weight measuring means 152 such as a load cell and a reading device (not shown) are provided. As the reading device, a barcode reader, a radio frequency identification (RFID) reader, or the like can be employed.

When the medicine container 2C is set in the medicine container inlet 151, the total weight of the medicine container 2C is measured inside and stored in the memory of the control device 47. In addition, a barcode (not shown) installed on the drug container 2C is read by a barcode reader or the like, and the drug container 2C is conveyed to a predetermined position in the drug shelf area 103 by the drug container moving device 102. And keep it.

Here, in this embodiment, the medicine container moving device 102 has the hand part 112 of the electromagnet 170. In this embodiment, the electromagnet 170 is brought close to the transport iron plate portion 157 of the medicine container 2C as shown in FIG. 31, and thereafter, the electromagnet 170 is energized to adsorb the transport iron plate portion 157. The container 2C is held and moved.

In addition, a two-sided open-type container, such as the second form of the drug container 2B (Fig. 9), has no cover, and when it is in a horizontal position, a drug container 2B of a type with a large open area corresponding to the ceiling surface. In the case of use, after weighing in a separate dispensing table or the like, or injecting an unweighed drug from the upper side in which the drug container 2B is opened (the upper side when the drug container 2B is in a horizontal position), the drug container input port 151 To set. When the drug container 2B of the second form is set, the total weight of the drug container 2B is measured, stored in the memory of the control device 47, and then the drug container moving device 102 It is conveyed directly to the approved drug feeder 50, and the amount of the drug based on the prescription information is dispensed to the powder drug dispensing device 202.

The control of the entire drug dispensing device 100 is substantially the same as the flowchart of FIG. 32.

Hereinafter, the operation of the entire drug dispensing device 100 will be described according to the flowchart of FIG. 32.

In this embodiment, as shown in FIG. 32, the prescription reading means 46 reads the contents of the prescription, so that all operations are started.

That is, in Step 1, when the contents of the prescription are input, the flow proceeds to Step 2, and immediately the carrying out operation of the medicine container 2C is started. More specifically, the medicament container moving device 102 is driven and selects a medicament container 2 in which a medicament matching a prescription is accommodated from among a plurality of medicament containers 2 arranged in the medicament shelf area 103, It is installed in the main body device 3 of the medicine feeder 50. In addition, at this time, the tab portion 147 of the movable lid portion 134 is pressed by a pressing piece (not shown) to open the movable lid portion 134, and the movable lid portion ( 134) remains open.

Then, the flow proceeds to Step 3 to energize the electromagnets 30a and b, and the medicine container 2C is fixed to the shaking table 20.

After that, the process proceeds to step 4 and timer timing is started. This timer prescribes the time for judging whether or not the medicine container 2C is installed normally, and is extremely short, for example, about 1 second.

Until the timer expires, if energization is confirmed between all of the contact sensors 33a, b, c, and d (Yes in step 5), it is determined that the medicine container 2C is installed in a normal posture, Go to step 6. On the other hand, if the contact sensors 33a, b, c, d cannot confirm contact even after waiting for a certain period of time (step 12), there is a high possibility that there is an abnormality such as a foreign object on the shaking table 20. Going to 13, a series of operations are retried. More specifically, energization of the electromagnets 30a and b is stopped, the drug container moving device 102 is driven to lift the drug container 2C by the hand part 112 again, and the drug container 2C is removed. It is installed in the main body device 3 of the medicine feeder 50 again, and the operation after step 3 is performed again.

When the energization by step 5 is confirmed by the first trial or re-trial, and the process proceeds to step 6, the weight measurement of the drug container 2C is started. That is, the raw weight G of the drug container 2C is measured and stored, and the current weight g of the drug container 2C is monitored.

Then, the flow proceeds to Step 7, and while the vibration of the shaking table 20 is started, the dispensing dish 212 of the powdered medicine dispensing device 202 is rotated.

Then, the flow proceeds to step 8, and timer timing is started. In the succeeding step 9, while monitoring the weight change of the medicine container 2C per fixed time, it waits for a predetermined amount of powdered medicine to be dispensed in step 10.

That is, the change in the weight of the medicine container 2C is monitored, and in step 9, it is confirmed that at least a certain or more weight reduction continues per certain time. If the weight decrease of at least a certain amount per certain time continues, since the drug is normally falling from the drug container 2C, the flow proceeds to step 10, and it is checked in step 10 whether or not a predetermined amount of powdered drug has been dispensed. When the dispensing amount of the powdered medicine is insufficient, the process returns to step 9. In this way, it waits for a predetermined amount of powdered medicine to be dispensed while confirming the drop of the medicine in Steps 9 and 10.

That is, in step 10, it waits for the difference between the original weight G of the medicine container 2C and the current weight g to become a desired dispensing amount. Then, when the desired dispensing amount is reached, the flow proceeds to step 11 and the vibration of the shaking table 20 is stopped.

The process after that is the same as the known drug dispensing device 100, and the drugs are divided and scraped off, and individually packaged.

In addition, if the weight drop of the drug container 2C is stopped while the desired dispense amount is reached, it is not possible to confirm the continuation of the fall of the powdered drug, and it is expected that the powdered drug in the drug container 2C will become insufficient. The process proceeds to 14, and an error indicating that the powdered medicine is insufficient is displayed, and a series of steps is ended.

When a series of discharging steps or packaging steps are completed, the electromagnet is stopped and the drug container moving device 102 is operated to return the drug container 2C to its original position.

Here, as a unique configuration of the drug dispensing device 100 of the present embodiment, when the drug container moving device 102 is operated to return the drug container 2C to its original position, the total weight of the drug container 2C is Reweigh. More specifically, when returning the drug container 2C to its original position, the drug container 2C is once moved to the drug container inlet 151, and the drug container is placed in the weight measuring means 152 installed at the drug container inlet 151. Load (2C) and reweigh the total weight of the medicine container (2C).

Then, the total weight of the drug container 2C at the beginning (just before discharging the current drug) and the total weight of the drug container 2C after discharging the drug are compared. And it is confirmed that the difference between the two is consistent with the dispensing amount of the drug discharged during the above process. In other words, the process of checking the amount of discharge is carried out.

Alternatively, the weight of the drug container 2C by the weight measuring means 152 installed in the drug container inlet 151 and the weight of the drug container 2C after discharging the drug measured by the drug feeder 50 are compared, Confirm that both are in agreement. In other words, a verification process is performed to determine whether the weight measuring means 25 of the drug feeder 50 is accurate.

And as a result of re-weighing the total weight of the medicine container 2C, if the total weight of the medicine container 2C is normal, the medicine container moving device 102 is operated to return the medicine container 2C to its original position. If there is an abnormality in the total weight of the medicine container 2C, an alarm is immediately issued and the pharmacist is notified.

Next, a method of using the drug container 2B of the second form and the drug container 2E of the fifth form will be described.

The drug containers 2B and 2E of the second and fifth embodiments are used when distributing powdered drugs or the like manually. That is, there are drugs that are not suitable to be stored in the drug container storage shelf 101 of the drug dispensing device 100 due to reasons such as less frequently used drugs, highly toxic drugs, high hygroscopicity, or weak at high temperatures. . Alternatively, it may be necessary to crush tablets or capsules to prescribe.

In such a case, the second and fifth forms of drug containers 2B and 2E are fixed to the shaking table 20 of the drug feeder 50, and an approximate amount of the drug is delivered from the open upper side to the drug container 2B, 2E). In the case of using the drug container 2E of the fifth aspect, the large lid 301 is removed to open the opening 300 and the drug is injected from the opening 300. After that, the weight of the drug container 2B is measured. That is, the raw weight G of the drug containers 2B and 2E is measured and stored, and the current weight g of the drug containers 2B and 2E is monitored.

After that, while starting the vibration of the shaking table 20, the dispensing dish 212 of the powdered medicine dispensing device 202 is rotated, and the difference between the original weight G of the drug containers 2B and 2E and the current weight g is Wait for the amount to be dispensed. And when the desired amount of delivery is reached, the vibration of the shaking table 20 is stopped.

In the embodiment described above, the powdered medicine was supplied to the distribution plate 212 of the powdered medicine dispensing device 202 using the medicine feeders 1 and 50, but the medicine packaging device 203 directly from the medicine feeders 1 and 50 You may supply powdered medicine to it.

It is also considered to supply tablets or capsules using the drug feeders 1 and 50 of the present invention.

In the embodiment described above, in the medicine feeders 1 and 50, the contact sensors 33a, b, c, and d are provided at four corners of the shaking table 20, but the number of contact sensors is arbitrary. However, in order to determine whether the shaking table 20 is in close contact with and adhered to the bottom of the medicine container 2A, 2B, 2C, 2D, 2E, at least two or more contact sensors in the longitudinal direction of the shaking table 20 It is preferable that it is installed. In addition, in order to confirm that the axis of the medicine container (2A, 2B, 2C, 2D, 2E) and the axis of the shaking table 20 coincide, at least two contact sensors are installed in the width direction of the shaking table 20 It is desirable to be.

In the embodiment described above, the weight of the drug container 2C immediately after installation on the shaking table 20 is stored as the original weight G, and the current weight of the drug container 2C is the current weight g, and the difference between the two is Although it was set as the discharge amount of the powdered drug, the discharge amount of the powdered drug may be calculated from the total detected weight of the weight measuring means 25. That is, it is the weight including the weight of the device such as the shaking table 20, and the detected weight of the weight measuring means 25 immediately after the medicine container 2A, 2B, 2C, 2D, 2E is installed on the shaking table 20 is the original weight G And the weight detected by the weight measuring means 25 during discharging of the powdered drug may be the current weight g, and the difference between the two may be the discharged amount of the powdered drug.

In the embodiment described above, electromagnets 30a and 30b are employed as container holding means, and a configuration in which the drug container 2 is directly adsorbed by the electromagnets 30a and 30b is adopted. That is, in the embodiment described above, a container holding means using magnetic force is employed.

However, the present invention is not limited to this configuration, and the medicine container 2 may be held by other mechanical means. For example, a configuration in which the drug container 2 is mechanically held by operating any engaging member or fitting member by a solenoid, a small motor, an air cylinder, or the like can also be adopted.

In addition, in the above-described embodiment, the medicine container 2 is fixed to the shaking table 20 by energizing the electromagnets 30a and 30b. However, a permanent magnet is used, or a permanent magnet and an electromagnet are used together to form the medicine container 2 It may be fixed to the shaking table 20.

Specifically, instead of the electromagnets 30a and 30b, a magnet having a structure called a non-exciting electromagnet or a self-holding solenoid is adopted as the container holding means.

The magnetic holding solenoid and the like described above are a combination of a permanent magnet and an electromagnet, and are usually mainly exhibited an adsorption force by a permanent magnet. In addition, when the magnetically attached thing is removed from the magnetic holding solenoid or the like, the electromagnet is energized, and a magnetic force in the opposite direction to the permanent magnet is generated.

Alternatively, even during adsorption, the electromagnet is energized to generate a magnetic force in the same direction as that of the permanent magnet, and upon separation, a reverse current flows to generate a magnetic force in the opposite direction to the permanent magnet.

Since the shapes of the electromagnets 30a and 30b and the self-holding solenoid are similar, the shape of the main body device 3 is the same as in Figs. 19 to 25 described above even when the self-holding solenoid is employed. Referring to Figs. 19 to 25 and 32, the container holding means will be described as self holding solenoids 30a and 30b.

In the case of using the self-holding solenoids 30a, 30b, in step 2 above, when the carrying out operation of the drug container 2 is started, the self-holding solenoids 30a and 30b are energized to generate magnetic force. Keep it under control.

And similarly to the above-described embodiment, the carrying out operation of the medicine container 2 is started. A drug container 2C in which a drug matching a prescription is accommodated from among the plurality of drug containers 2 is selected, and is installed in the main body device 3 of the drug feeder 50.

Then, energization to the magnetic holding solenoids 30a and 30b is stopped, and the magnetic force of a permanent magnet is exerted to fix the medicine container 2 to the shaking table 20.

The following steps are the same as in the above-described embodiment, but when the drug container 2 is removed from the shaking table 20, the magnetic force is energized again to the magnetic holding solenoids 30a and 30b to cancel the magnetic force of the permanent magnet.

Since the self-holding solenoids 30a and 30b maintain their adsorption force in a state in which they are not energized, power consumption is less than that of a configuration using the electromagnets 30a and 30b. In that respect, the configuration employing the self-holding solenoids 30a and 30b is superior to the configuration employing the electromagnets 30a and 30b.

Further, the self-holding solenoids 30a and 30b have little power consumption and a low amount of heat generated. Therefore, it is also recommended in that the influence on the drug in the drug container 2 is small.
In the embodiment described above, the protrusion 16C is provided on the side of the drug container 2C and is engaged with the side of the main body device 3 to prevent the drug container 2C from advancing. A configuration in which a protrusion is formed to engage a part of the drug container 2A, 2B, 2C, 2D, 2E side, or forms a recess in the drug container 2 is also effective.

In the above-described embodiment, as the vibration isolating members 40 and 41, a combination of a spring and a vibration isolating rubber has been exemplified, but a vibration isolating member made of a spring alone may be employed, or a vibration isolating member made of only resin or the like may be adopted.

In the above-described embodiment, the vibration isolating member 40 is provided between the intermediate stand 22 and the vibration isolating table 23 to prevent vibration from being transmitted to the vibration isolating table 23, but in addition to this configuration or instead of this configuration On, it is also recommended to eliminate the effects of vibration by software. For example, a method of removing the influence of vibration by Fourier transforming the detected value of the weight measuring means 25 is considered.

In the above-described embodiment, the total weight of the drug container 2C was re-weighed using the weight measuring means 152 installed in the drug container inlet 151, but the weight measuring means was installed at another part to make the drug container 2C. The total weight of may be reweighed. In addition, the total weight may be re-weighed by placing the medicine container 2C again on the other medicine feeders 1 and 50 from the medicine feeders 1 and 50 used for discharging the medicine. That is, by re-weighing, if it can be found that there is some abnormality in the weighing value, it leads to detecting the failure of the weighing means 25 and 152 of either of the compared weights.

In addition, the step of re-weighing is not essential and may be omitted.

In the above-described embodiment, the difference between the original weight G of the drug container 2C and the current weight g is adopted to stop the vibration of the shaking table 20 after the desired dispensing amount is reached, but the original weight G is taken into consideration of the time lag. Wow, it is also recommended to stop the vibration of the shaking table 20 in a state where the difference between the current weight g is slightly less than the desired delivery amount.

In addition, in the embodiment described above, the decrease in the weight of the drug container 2C was monitored and it was confirmed that the drug was continuously falling, but a powder drop sensor was separately installed, and the drug was continued using the powder drop sensor. And you may confirm that it is falling.

In the embodiment described above, the container moving means employs a type having a hand 45 (Fig. 1) for holding the medicine container 2, or a hand part 112 (Fig. 30) using an electromagnet. In the former hand 45, the hand 45 itself operates independently of the arm. In the latter hand part 112, the hand part 112 itself is integral with the arm and does not move relative to the arm, and holds the medicine container 2 by physical adsorption.

In addition, a hand holding the medicine container 2 by physical fitting or engaging engagement is considered.

For example, like the combination of the medicine container 2F and the hand 172 shown in FIG. 33, the two are engaged by relative movement.

That is, in the medicine container 2F, as shown in FIG. 33, the guide rail 173 is provided on the peripheral wall upper surface 51D. The guide rail 173 has engaging grooves 174 on both sides.

In one hand 172, a groove 175 having a "C" shape in cross section is provided. The groove 175 is open as shown in the figure at the tip side in the longitudinal direction. In addition, the rear end in the longitudinal direction of the groove 175 is closed (not shown).

The cross-sectional shape of the groove 175 of the hand 172 is approximate to the cross-sectional shape of the guide rail 173, and both can be engaged, and in the engaged state, both can be moved only linearly and separated. I can't go out.

The hand 172 is provided integrally with the robot arm.

When holding the medicine container 2F with the hand 172 shown in FIG. 33, the robot arm is operated, the hand 172 is brought close to the medicine container 2F, and the opening end of the groove 175 The ends of the guide rail 173 are aligned. Then, the robot arm is moved linearly, and the guide rail 173 is inserted into the groove 175. As a result, the medicine container 2F is in a state that has a degree of freedom only in the direction along the guide rail 173 and is substantially held by the hand 172.

In addition, the main body device 3 has a member through which electromagnets 30a and 30b, self-holding solenoids 30a and 30b, and vibrating means (piezoelectric elements) are energized, and thus heat is easily generated. When there is a possibility that heat generation may affect the medicine in the medicine container 2, it is preferable to provide a cooling means for cooling the main body device 3.

As an example of the cooling means, a configuration in which a cooling fin 305 is provided in the main body device 3 or a blower 306 is provided in the vicinity as shown in FIG. 46 is considered.

In addition, as a more advanced configuration, a configuration in which the vibration pattern of the shaking table 20 can be changed according to the type of drug, discharge timing, and total discharge is recommended.

Drugs have different particle diameters and hygroscopic properties depending on the type. Therefore, when the shaking table 20 is vibrated, the behavior of the drug in the drug container 2 differs depending on the drug.

There are drugs that rectify and flow easily when subjected to vibration, and drugs that are difficult to rectify. In addition, the amount of movement by one vibration varies depending on the type of drug.

In addition, there is a problem that the discharge of the drug is not stable at the initial stage of discharge of the drug.

Accordingly, the frequency (frequency) and amplitude per unit time can be changed, and the frequency or amplitude is changed according to the type of drug, discharge timing, and total discharge.

For example, the ease of discharging of drugs is tested in advance, and all drugs scheduled to be discharged are divided into a plurality of stages by the drug feeders 1 and 50. This is called, for example, a "flow coefficient", and drugs are classified into a flow coefficient of 1 to 3.

In addition, the discharge level is divided into multiple stages by the total amount of the drug discharged. For example, emissions are classified every 20g and will be referred to as “emissions 20, emissions 40, and 60 emissions”.

Also, according to the frequency and amplitude of the vibration, the vibration level is divided into multiple stages. This is referred to as "vibration level 1, vibration level 2", for example, and changes from vibration level 1 (minimum vibration) to vibration level 20 (maximum vibration), for example.

Then, an appropriate vibration level is selected according to the "flow coefficient" and the "discharge amount". In addition, the vibration level distinguishes between the vibration level at the initial stage of discharge and the vibration level at the ballast.

For example, if it is a drug that is easily discharged such as ``flow coefficient 1'' and the total discharge amount is low such as ``discharge amount 20'', vibration is started with a slow vibration such as vibration level 3, and after a certain period of time, Switch to strong vibration, such as vibration level 10. Alternatively, the vibration intensity of the shaking table 20 is switched to a feedback control method so that the amount of discharge h per unit time becomes constant, centering on a strong vibration such as the vibration level 10.

In addition, if it is a drug that is difficult to be discharged such as ``flow coefficient 3'', and the total amount of discharge is large as referred to as discharge amount 80, vibration starts with strong vibration such as vibration level 11, and after a certain period of time, vibration Switch to a stronger vibration, like level 15. Alternatively, with the strong vibration as the center of the vibration level 15, the feedback control is performed so that the discharge amount h per unit time becomes constant.

In addition, it is desirable to provide an assay function for verifying whether the weight measuring means 25 of the drug feeders 1 and 50 are accurate.

For example, a weight member whose weight is known is prepared, and the weight is installed in the drug shelf area 103 or the like. Then, the weight member is moved to the shaking table 20 by a robot 43 or the like, and the weight of the weight member is measured by the weight measuring means 25. If the measured value coincides with the weight of the weight, the weight measuring means 25 is correct, otherwise, it is a failure of the weight measuring means 25.

Further, as the weight member, the drug container 2 itself can also be utilized. For example, innocent powder or granular material is put in the medicine container 2, and the weight is measured in advance. The medicine container 2 used as the weight member is provided together with the other medicine container 2 in the medicine shelf area 103 or the like. Then, if necessary, the weight medicine container 2 is moved by a robot 43 or the like, installed on the shaking table 20, and the weight measuring means 25 is inspected.

Although the method of installing the medicine container 2 in the medicine shelf area 103 is arbitrary, for example, as shown in FIG. 47, a medicine shelf 328 in which a plurality of vertical walls 320 and a mounting table 323 are installed is provided. Is considered. An upper engaging portion 325 is installed on the vertical wall 320, and a lower engaging portion 326 is installed on the mounting table 323. The upper engaging portion 325 and the lower engaging portion 326 maintain a protruding state by a pressing member (not shown).

In this embodiment, in the drug container 2 to be adopted, in addition to the configuration of the drug container 2D of the fourth embodiment, a locking projection 370 is provided on the lid member 120D. Further, there is a recess 371 at the rear end of the medicine container 2D.

The upper engaging portion 325 rotates upward as indicated by an arrow in the drawing by pressing the lid member 120D of the medicine container 2D. The lower engaging portion 326 is lowered in the mounting table 323 by pressing the iron plate portion 6 of the medicine container 2.

When the drug container 2D is pressed against the drug shelf 328, the upper engaging portion 325 and the lower engaging portion 326 resist the force of the pressing member and escape. And when the medicine container 2D reaches a predetermined position, the upper engaging portion 325 is returned by a pressing member (not shown), and engages with the engaging projection 370 of the lid member 120D. Further, the lower engaging portion 326 is returned by a pressing member (not shown), and is engaged with the recessed portion 371 at the rear end of the drug container 2D.

When taking out the drug container 2D, the drug container 2D is held by a robot 43 or the like, and separated from the drug shelf 328. At that time, the upper engaging portion 325 and the lower engaging portion 326 are released by resisting the force of the pressing member, and the engaging portion is released.

In addition, for example, as shown in FIG. 48, a drug shelf 345 in which a plurality of vertical walls 340 and a mounting table 343 are installed is considered. The vertical wall 340 has an opening 346, and in the opening 346, a protrusion 347 (a storage portion side upper engaging portion) protrudes upward.

Further, the mounting table 343 is provided with a storage portion-side lower engaging portion 348. The storage portion side lower engaging portion 348 is a protrusion.

In the present embodiment, the drug container 2 to be adopted has a recess 350 at the rear end of the drug container 2D of the fourth embodiment. The container side engaging portion 352 is provided on the lower surface 12D of the peripheral wall of the container body 5D. The position of the container-side engaging portion 352 is the lower surface of the peripheral wall 12D and is a position slightly closer to the lid member 120D than the center, and when the medicine container 2D is installed on the shaking table 20, the shaking table 20 ) Is never touched. The container-side engaging portion 352 has a ring shape, and a rectangular hole 351 penetrating in the longitudinal direction of the drug container 2D is provided.

In the present embodiment, the container side engaging portion 352 of the drug container 2D is inserted through the opening 346 to push down the drug container 2D, and the hole 351 of the container side engaging portion 352 ) By inserting the protrusion of the drug shelf 345 (the storage portion side upper engaging portion 347), the drug container 2D is suspended on the drug shelf 345.

In addition, at this time, the protrusion 348 (the storage portion side lower engaging portion) provided on the mounting table 343 is engaged with the concave portion 350 of the drug container 2.

Among the drug containers 2 described above, in the drug container 2 of the type with a lid, in principle, the lid member 120 is removed and the drug is injected, but the drug container 2E of the fifth form is a movable lid. Since the removal of the part 134E is easy, the medicine can be injected without removing the cover main body 125E. In that case, as shown in Fig. 45, if the funnel-shaped member 355 is attached to the portion of the movable lid portion 134E and the operation is performed, the drug is difficult to drop.
