[0023]
  Here, the structure of the shutters 24, 39A, 39B, 43 and 12 will be described with reference to FIGS. The shutters 24, 39A, 39B, and 43 provided in each chute have the same structure, and are pivotally supported on one side by a frame 51 to open and close the passage as shown in FIG. The shutter plate 52, a spring 53 that urges the shutter plate 52 to be closed at all times, and a solenoid 58 that rotates the shutter plate 52 via a fixture 54, a shaft 56, and a connector 57. Yes.
[0024]
  When the solenoid 58 is energized, the plunger 59 that is rotatably connected to the connector 57 is attracted, and the shutter plate 52 is opened against the urging force of the spring 53. When the solenoid 58 is deenergized, the shutter plate 52 is closed by the spring 53, and the plunger 59 projects from the solenoid 58. With the shutter plate 52 closed, the medicines discharged from the tablet cases 3, 4, 6,... Above the shutters 24, 39A, 39B, 43 and falling in the respective chutes are placed thereon. It is received, opened, and dropped onto the hopper 11.
[0025]
  Next, the shutter 12 has a rectangular cylindrical main body 62, a shutter plate 63 pivotally supported by the main body 62 on one side to open and close the main body 62, and the shutter plate 63 is always closed. And a solenoid (not shown) for rotating the shutter plate 63 and a lower end of the main body 62, and inserted from above into the wrapping paper 15 folded in a substantially V shape. It is comprised from the insertion pieces 64, 66, 67 etc. which are expanded.
[0026]
  Then, by energizing the solenoid, the shutter plate 63 is rotated clockwise in FIG. 8 against the urging force of the spring and opened. When the solenoid is de-energized, the shutter plate 63 is pulled up by a spring to close the passage in the main body 62. The medicine that has fallen into the hopper 11 with the passage closed is received thereon, opened, and dropped into the wrapping paper 15.
[0027]
  Here, the positions of the shutters 24, 39A, 39B and 43 provided in the chutes 22, 37A, 37B and 42 will be described. Each of the shutters 24, 39A, 39B, and 43 has a medicine discharged from the uppermost tablet case 3 of each case storage unit 8, 33A, 33B, and 41 falling in each chute to cause each shutter 24, 39A, The time required to reach 39B and 43 is equivalent to the time required for the medicine to fall from the shutters 24, 39A, 39B and 43 into the hopper 11 and reach the shutter 12 (e.g., 0.8 in the apparatus of the embodiment). Second). That is, in the embodiment, the position is set at a position corresponding to the upper side of the lowermost stage (additional medicine feeder 46 for the moving unit 2B) in each case storage unit 8, 33A, 33B and 41.
[0028]
  Next, in the functional block diagram of FIG. 9, the control device 61 is constituted by a general-purpose microcomputer 69. The input of the microcomputer 69 includes prescription data and the medicine from an input device (such as a personal computer) not shown. Agent detection signals from the detectors 30 are input. The output of the microcomputer 69 includes the discharge mechanisms 31 of the tablet cases 3, 4, 6, the shutters 24, 39 A, 39 B, 43, 12, the printer 10, the sealer 13, and the wrapping paper 15. A feeder 68 is connected.
[0029]
  Next, the usage and operation of the medicine supply device 1 of the present invention will be described with reference to FIGS. Note that the shutters 12, 24, 39A, 39B, and 43 are closed when the power is turned on. In addition, when the main body side case storage portion 8 and the movement side case storage portions 33A and 33B and the extension unit 9 of each of the movement units 2A and 2B are attached, the extension side case storage portion 41 stores predetermined medicines. The tablet case 3, 4 or 6 is attached.
[0030]
  In this case, a medicine with a large amount of use or a medicine with a large individual size is stored in a large-capacity tablet case 6 and a medicine with a smaller amount or a smaller medicine is stored in a medium-capacity tablet case 4 and is most used. A medicine with a small amount or a medicine with a small size is stored in a small-capacity tablet case 3. As described above, the tablet cases 3, 4 or 6 are arranged side by side on the shelf device 26. In this case, a tablet case having the same capacity is attached on the same shelf device 26.
[0031]
  Next, the medicine discharging operation from the tablet cases 3, 4, 6 by the microcomputer 69 will be described with reference to FIGS. When an operator inputs prescription data from the input device (personal computer) based on a doctor's prescription, the microcomputer 69 pastes the contents of the prescription data on the data table of FIG.
[0032]
  Here, numbers in FIG. 10 (circle 1 (meaning a circled number in the figure; the same applies hereinafter), circle 2...) Are addresses assigned to the tablet cases 3, 4, and 6. It consists of three data: number, number of drugs to be discharged (number of drugs), and counter. This counter represents the position of the shelf device 26 to which the tablet case is attached, and the numbers increase sequentially as 2, 3. And the content of prescription data is affixed as the number of agents corresponding to each case number. Accordingly, the number of medicines in the tablet case containing medicines that do not need to be discharged is naturally zero.
[0033]
  When the microcomputer 69 starts the medicine discharge operation, the case drive flag is set (“1”) in step S1 of the flowchart of FIG. 11, and the head address (circle 1) is set in step S2, and step S3 is executed. Then, it is determined whether or not the counter of the address is 1. If it is 1, the process proceeds to step S4, where it is determined whether the case number is not 0. If not, the process proceeds to step S5, where it is determined whether the number of agents is not 0. Here, if it is not 0, it will progress to step S6 and will start drive of the discharge mechanism 31 of the tablet case 3 (4, 6) of the said address.
[0034]
  Next, in step S7, the counter of the address is set to -1, and in step S8, the next address (in this case, circle 2) is set, and the process proceeds to step S9. In step S9, it is determined whether all addresses have been completed. If not, the process proceeds to step S3. If the counter is not 1 in step S3, the process proceeds to step S13 to determine whether the counter is not 0. If it is not 0, the process proceeds to step S7, and if it is 0, the process proceeds to step S8.
[0035]
  If all addresses are completed in step S9, the process proceeds to step S10, waits for 100 ms, and proceeds to step S11 to determine whether the counters of all addresses are 0 or not. If it is not 0, the process returns to step S2, and if it is 0, the process proceeds to step S12 to determine whether or not the case drive flag is reset (“0”). If it is not 0, step S12 is repeated until it becomes 0.
[0036]
  With the above control, all addresses are scanned from the uppermost shelf device 26, the driving of the discharge mechanism 31 of the tablet case 3 (4, 6) whose number of agents is not 0 is started, and this is moved to the lowermost shelf device 26. Until the number of medicines is not 0, that is, the ejection mechanisms 31 of all tablet cases 3 (4, 6) for which the medicine is requested to be dispensed according to the prescription data are started.
[0037]
  Next, the flowchart of FIG. 12 shows the operation of counting the discharged medicine, and is interrupted by the flowchart of FIG. 11 while the case drive flag is set. That is, the microcomputer 69 determines whether or not the case drive flag is reset in step S14. If it is set, the microcomputer 69 proceeds to step S15 and sets the head address.
[0038]
  In step S16, it is determined whether or not there is a drug detection signal from the drug detector 30 corresponding to the tablet case 3 (4, 6) at the address. If a signal is input, the number of drugs is decreased by -1 in step S17. . Next, in step S18, it is determined whether or not the number of agents is 0. If it is not 0, the process proceeds to step S20. move on.
[0039]
  In step S20, the next address is set, and in step S21, it is determined whether or not all addresses have been completed. If not, the process returns to step S16. If completed, the process proceeds to step S22 and the number of agents for all addresses is determined. Whether or not is 0 is determined. If it becomes 0, the process proceeds to step S23 to reset the case drive flag.
[0040]
  In this way, the microcomputer 69 counts the discharged medicine one by one until the number of drugs reaches zero for all tablet cases 3 (4, 6), and all of the drives that start driving the discharge mechanism 31 in the flowchart of FIG. The discharge mechanism 31 is stopped when the number of drugs based on the prescription data is discharged for the tablet case. Thus, a predetermined number of medicines are discharged.
[0041]
  Next, referring to the timing chart of FIG. 13, the medicine discharge operation under the control of the microcomputer 69 and the operation timing of each shutter 24 (39A, 39B, 43), shutter 12, printer 10, sealer 13 and feeder 68. Will be explained. 13 shows the discharging operation of the tablet case 3 (4, 6) positioned above each shutter 24 (39A, 39B, 43).
[0042]
  At the start of operation (time 0), the microcomputer 69 first executes the above discharge operation (first discharge operation circle 1) for the tablet case 3 (4, 6) located above the shutter 24 (39A, 39B, 43). (Run for 0.2 seconds). The discharged medicine is received on each shutter 24 (39A, 39B, 43) as described above. In this case, the upper tablet case (for example, the uppermost tablet case) 3 starts the discharge operation earlier (up to 0.3 seconds earlier in the embodiment) than the lower tablet case.
[0043]
  Here, since the drop time from the uppermost tablet case is set to 0.8 seconds as described above, after the discharge operation of the uppermost tablet case is completed, the tablet case below the upper case is discharged after 0.8 seconds. All of the drugs, including the drugs, are received on the shutter.
[0044]
  Next, 0.8 seconds after the end of the discharging operation of the uppermost tablet case 3, the shutter 24 (39A, 39B, 43) is opened, the medicine is dropped on the hopper 11, and the printer 10 and the feeder 68 are synchronized with each other. Operate for 0.4 seconds. The dropped medicine is all received on the shutter 12 after 0.8 seconds from the start of opening of the shutter 24 (39A, 39B, 43) as described above.
[0045]
  On the other hand, the microcomputer 69 starts the second discharging operation (circle 2) from the uppermost tablet case 3 when the shutter 24 (39A, 39B, 43) is opened. Similarly, for the lower tablet case, the second discharge operation (circle 2) starts 0.1 seconds before the shutter 24 (39A, 39B, 43) closes. That is, the second discharging operation is executed while the medicine discharged by the first discharging operation is falling on the shutter 12. The medicine discharged in the second discharging operation falls on the closed shutter 24 (39A, 39B, 43) and is received.
[0046]
  Since the uppermost tablet case 3 takes time to reach the shutter 24 (39A, 39B, 43), the shutter 24 (39A, 39A, 39B, 43) are closed. In addition, the tablet case 6 positioned below each shutter 24 (39A, 39B, 43) executes a discharging operation in synchronization with the second discharging operation and is directly dropped onto the shutter 12.
[0047]
  On the other hand, the microcomputer 69 operates the sealer 13 for 0.4 seconds after the feeder 68 operates (0.8 seconds after the shutter 24 (39A, 39B, 43) starts opening operation) to seal the wrapping paper 15. After the operation of the sealer 13 is finished, the shutter 12 is opened, and the medicine discharged for the first time (including the medicine discharged from the tablet case below the shutter 24) is dropped into the wrapping paper 15. This is repeated thereafter.
[0048]
  Thereby, in the case of the Example, the operation | movement space | interval of the shutter 12 was set to 1.0 second, and the packaging capability was set to 60 packets / minute.
[0049]
  Here, when each shutter 24, 39A, 39B, 43 is attached to the lowermost part of each chute 22, 37A, 37B, 42, the time required for the medicine to fall on the shutter from the uppermost tablet case is an example. Takes 1 second. Therefore, even if the time required for the medicine to drop from the shutters 24, 37A, 37B, 42 to the shutter 12 is reduced to 0.6 seconds, the waiting time until the shutters 24, 37A, 37B, 42 are closed increases. Therefore, as shown in FIG. 14, the operation interval of the shutter 12 is 1.5 seconds as a result, and the packaging capacity is limited to 40 packets / minute in the embodiment.
[0050]
  However, according to the present invention, the time taken for the medicine discharged from the uppermost tablet case 3 (4, 6) to reach the shutters 24, 37A, 37B, 42, and the medicine are the shutters 24, 37A, 37B, Since the time until reaching the shutter 12 from 42 is set to be equal, when discharging the medicine from the tablet case above the shutters 24, 37A, 37B, 42, first, the shutters 24, 37A, 37B, The medicine received on the 42 and placed next to the shutter 24, 37A, 37B, 42 before the medicine is discharged from the tablet case, and the medicine received on the shutter 24, 37A, 37B, 42 Is received by the shutter 12, and the medicine discharged from the tablet case is closed again. 24, 37A, 37B, and 42 are repeatedly executed, so that the tablet case and the shutters 24, 37A, 37B, and 42 and the shutters 24, 37A, 37B, and 42 to the shutter 12 are repeatedly performed. In this way, the medicine can be dropped and moved in parallel.
[0051]
  In particular, the upper tablet case, which takes time to fall on the shutters 24, 37A, 37B, 42, discharges the drug earlier than the lower tablet case, so the time required for transporting the drug is reduced. As a result, it can be remarkably shortened. As a result, the medicine supply operation is remarkably speeded up, and it is possible to achieve a significant improvement in business efficiency.
[0052]
【The invention's effect】
  As detailed above, according to the present invention,First shutterThe upper tablet case, which takes time to fall into, discharges the drug earlier than the lower tablet case,First shutterSince the medicine is discharged at the same time as the opening of the medicine, the time required for transporting the medicine can be remarkably shortened as a whole. Thereby, the medicine supply operation is remarkably speeded up, and it is possible to realize a significant improvement in business efficiency.
[0053]
  In particular, the time until the medicine discharged from the uppermost tablet case reaches the first shutter is equal to the time until the medicine reaches the second shutter from the first shutter.Set,When discharging the medicine from the tablet case above the first shutter, the medicine is first received and placed on the first shutter, and then from the tablet case or another tablet case above the first shutter. The first shutter is opened at the start of discharging the medicine, the medicine received by the first shutter is received by the second shutter, and the medicine discharged from the tablet case is closed again. Repeat the action of receiving atBecause I tried to runIt becomes possible to cause the medicine to fall and move in parallel between the tablet case and the first shutter and between the first shutter and the second shutter.
[0054]
  As a result, the medicine supply operation can be further speeded up. The medicine in the tablet case below the first shutter is discharged at the next medicine discharge from the tablet case above the first shutter, and is configured to be directly received by the second shutter. The medicine in the tablet case below the shutter can be quickly supplied without any trouble.
