【Example】
Hereinafter, the present invention will be described with reference to the illustrated embodiment. In FIG. 1, reference numeral 1 denotes a conveyance wheel that holds and conveys a syringe 2. The transport wheel 1 is disposed adjacent to the rotary syringe processing device 3.
As shown in FIG. 3, the syringe 2 is formed in a substantially cylindrical shape, and has a small-diameter distal end portion 2 a at one end in the axial direction, and on the outer peripheral side of the opening that becomes the other end in the axial direction. A collar portion 2b is provided.
The syringe processing device 3 is intermittently rotated in the clockwise direction, and is configured to suspend and convey each syringe 2 in the vertical direction so that the distal end port portion 2a becomes the lower end and the collar portion 2b becomes the upper end. . In the process of suspending and transporting the syringe 2, the syringe processing device 3 first closes the seal member 4 by attaching the seal member 4 to the distal end portion 2 a of the syringe 2 (FIG. 3), and then a predetermined amount of the chemical solution 5 in the syringe 2. After that, the seal member 6 is fitted into the syringe 2 from the upper end opening of the syringe 2 to close the upper end opening. In addition, such a process by the syringe processing apparatus 3 is performed for every four syringes 2 that follow each other. The syringe 2 that has finished processing by the syringe processing device 3 in this way is discharged from the syringe processing device 3 by the transport wheel 1 that rotates intermittently in synchronization with the syringe processing device 3, and thereafter, by the transport wheel 1. After being conveyed, it is delivered to the conveying means 7 on the downstream side.
[0007]
By the way, the above-described processing is performed by the syringe processing device 3, but the syringe 2 after the processing by the syringe processing device 3 is finished, for example, is accurately fitted with the seal member 6 to be fitted to the upper opening. May not be. Such a syringe 2 must be discharged from the normal transport process as a defective syringe 2 because the chemical solution 5 in the syringe 2 may leak in the subsequent transport process.
Therefore, in this embodiment, a conventionally known inspection device 8 is provided at the end position in the conveyance process by the syringe processing device 3. The inspection device 8 inspects the four syringes 2 that follow each other after the processing by the syringe processing device 3 and determines which of these syringes 2 is defective. The determination result by the inspection device 8 is transmitted to the control device 11. Based on the determination result transmitted from the inspection device 8, the control device 11 controls the operation of a delivery device 12, which will be described later, and selects a defective syringe 2 from the syringes 2 that are transported by the transport wheel 1. It is extracted and discharged to the discharge chute 13.
[0008]
The transport wheel 1 is composed of a rotating body that is intermittently rotated in the direction of the arrow in synchronization with the syringe processing device 3, and the outer peripheral portion of the transport wheel 1 is provided with pockets 1 a composed of concave portions at equal circumferential positions. Yes.
An arcuate guide member 14 is disposed near the outer peripheral portion of the transport wheel 1 from the position of the outer peripheral portion of the syringe processing device 3 to the position of the transport means 7 along the outer peripheral portion. The conveying means 7 is provided continuously to the downstream end of the guide member 14.
The four syringes 2 that have finished processing in the syringe processing device 3 with the intermittent rotation of the syringe processing device 3 and the transport wheel 1 are engaged with the pockets 1a of the transport wheel 1 at the first delivery position A, thereby the syringes. It is discharged from the processing device 3. The syringe 2 engaged with the pocket 1a of the transport wheel 1 is supported on the collar 2b by the upper surface of the edge of the pocket 1a, and the outer peripheral portion that is adjacent to the collar 2b is engaged with the pocket 1a. ing.
The syringe 2 held in the pocket 1 a of the transport wheel 1 in this way comes into contact with the guide surface of the guide member 14 at the outer periphery. Thereby, the syringe 2 is reliably conveyed downstream without dropping out of the pocket 1a.
When the transport wheel 1 receives four syringes 2 sequentially from the syringe processing device 3 at the first delivery position A, the transport wheel 1 rotates intermittently with the four syringes 2 as one unit, and then downstream. It is designed to be transported to. When the four syringes 2 transported by the transport wheel 1 do not include the defective syringe 2, the four syringes 2 are delivered to the transport means 7 described above.
[0009]
On the other hand, when the defective syringe 2 is included in the four syringes 2 conveyed by the conveyance wheel 1, the defective syringe 2 is stored in the pocket of the conveyance wheel 1 by the delivery device 12 at the extraction position B. After being extracted from 1a, it is discharged to the discharge chute 13 at the discharge position C.
Before explaining the configuration of the delivery device 12, the configuration of the discharge chute 13 will be described. As shown in FIGS. 1, 2, and 4 to 6, the discharge chute 13 is provided in parallel so as to have the same height. It comprises a pair of plate-like members 15A and 15B. At the discharge position C where the defective syringe 2 is delivered by the delivery device 12, the upper ends of the plate-like members 15A and 15B are horizontal, and in the sliding section D adjacent to the discharge position C, the downstream side ( The upper ends of the plate-like members 15A and 15B are inclined so that the height on the right side) gradually decreases.
[0010]
Also, as shown in FIGS. 4 to 6, a lifter 9 is provided between the plate-like members 15A and 15B at the discharge position C so as to be movable up and down. At four positions in the longitudinal direction at the upper end of the lifter 9, there are formed engaging portions 9a that engage with the distal end portion 2a of the syringe 2 and a stepped portion adjacent thereto.
The lifter 9 is interlocked with a cylinder mechanism 19 attached to the frame vertically downward. When the cylinder mechanism 19 is in an inoperative state, the lifter 9 is positioned at the rising end indicated by an imaginary line in FIG. On the other hand, when the cylinder mechanism 19 is actuated, the lifter 9 is located at the lowered end position indicated by the solid line in FIGS.
When the lifter 9 is in the raised end position, the delivery device 12 inserts the defective syringe 2 between the plate-like members 15A and 15B at the discharge position C from above. Thus, the defective syringe 2 is supported in the vertical direction by engaging the lower end portion thereof with the engaging portion 9a of the lifter 9, and the collar portion 2b is the upper end of both plate-like members 15A and 15B. Is supported upward. Thereafter, the defective syringe 2 is released from the holding state by the delivery device 12 and is held by the plate-like members 15A and 15B and the engaging portion 9a of the lifter 9. Further, after this, the cylinder mechanism 19 is operated and the lifter 9 is lowered to the lower end position, so that the engaging portion 9a of the lifter 9 is separated from the distal end portion 2a of the defective syringe 2, and on the other hand, The flange portion 2b of the non-defective syringe 2 is supported by the upper ends of both plate-like members 15A and 15B. In this way, the defective syringe 2 is supported by the two plate-like members 15A and 15B at the discharge position C.
[0011]
Further, the support member 15A on the side of the transport wheel 1 is formed with a linear notch 15a in the longitudinal direction in the discharge position C, and in the longitudinal direction at a position adjacent to the support member 15A. Extrusion member 16 is provided along. The pushing member 16 is provided with a contact portion 16a that is positioned between the plate-like members 15A and 15B via the notch 15a of the support member 15A (FIG. 6). ).
The pushing member 16 is interlocked with a cylinder mechanism (not shown), and when the cylinder mechanism is in an inoperative state, the pushing member 16 is located at a retracted position slightly shifted from the discharge position C to the upstream end. On the other hand, when the cylinder mechanism is operated, the push-out member 16 is moved forward in the notch 15a to the advance end position that is the downstream end of the discharge position C. As the pushing member 16 is advanced in this manner, the defective syringe 2 supported at the discharge position C is pushed out from the discharge position C to the sliding section D. The defective syringe 2 fed into the sliding section D slides toward the downstream side in the sliding section D by its own weight, and a collection box (not shown) provided at the adjacent position from the downstream end of the sliding section D It is configured to be dropped and stored.

A cup-shaped contact member 22 is attached to the upper end of each air cylinder 21, and these four contact members 22 are located immediately below each syringe 2 that is temporarily stopped at the extraction position B.
The operation of each air cylinder 21 is controlled by the control device 11, and the control device 11 includes the four syringes 2 temporarily stopped at the extraction position B based on the signal from the inspection device 8 described above. Among them, it recognizes which syringe 2 is defective. Then, when the four syringes 2 are temporarily stopped at the extraction position B, only the air cylinder 21 on the lower side of the defective syringe 2 is operated, and the abutting member 22 attached thereto is indicated by an imaginary end. (See FIG. 6). When the contact member 22 is raised in this way, the upper end of the contact member 22 contacts the stepped portion of the syringe 2 from below and pushes up the syringe 2 from the pocket 1a by a predetermined dimension.
As a result, the defective syringe 2 is in a state in which the collar portion 2b and the outer peripheral portion on the lower side adjacent thereto are pushed up by a predetermined dimension above the pocket 1a. As described above, the defective syringe 2 is configured to be pushed up by a predetermined dimension by the contact members 22 of the push-up mechanism 17 when temporarily stopped at the extraction position B. The defective syringe 2 pushed up by the push-up mechanism 17 is then extracted from the pocket 1a by the delivery means 18 described later. In other words, in this embodiment, the non-defective syringe 2 is not pushed up by the contact members 22 of the push-up mechanism 17.

Then, the remaining two grippers 23 are provided on the upper surfaces of these two tip portions. The height of the two grippers 23 provided on the fourth support member 38 and the height of the two grippers 23 provided on the third support member 35 are adjusted to be the same height (see FIG. 2). Further, the distance between the two grippers 23 provided on the upper surface of the fourth support member 38 is such that when the syringe 2 on the transport wheel 1 side temporarily stops at the extraction position B, both outer sides in the left-right direction in FIG. The two syringes 2 are made to coincide with the distance apart.
Further, an air cylinder 41 is disposed in parallel with the guide rail 37 on the upper surface of the third support member 35 between the guide rails 37, and the tip of the air cylinder 41 is connected to the fourth support member 38. It is connected to the upper surface of the central part. The operation of the air cylinder 41 is also controlled by the control device 11. As the air cylinder 41 is actuated to advance and retract, the fourth support member 38 is advanced and retracted along the both guide rails 37 by a predetermined stroke. As shown in FIG. 1, when the fourth support member 38 is moved to the forward end along both guide rails 37, the two grippers 23 provided on the fourth support member 38 are provided on the third support member 35. The two grippers 23 protrude toward the transport wheel 1 by a predetermined dimension. In this state, when the third support member 35 is advanced toward the transport hole 1 along the guide rail 34, the four grippers 23 are positioned above the four syringes 2 temporarily stopped at the extraction position B. It is configured to be located. On the other hand, when the fourth support member 38 is retracted along the both guide rails 37 to the retracted end, the four grippers 23 are configured to be positioned on the same straight line parallel to the longitudinal direction of the discharge chute 13.

The operation of the air cylinder 42 is also controlled by the control device 11. When the engaging portion 23A is engaged with the lower side of the syringe 2 adjacent to the flange portion 2b from the lateral direction, the control device 11 operates the air cylinder 42 to lower the presser portion 23B from the rising end position by a predetermined amount. The pressing portion 23B covers the collar portion 2b of the syringe 2 from above. As a result, the collar 2b of the syringe 2 is supported by the engaging portion 23A and engaged with the presser portion 23B, so that the syringe 2 does not fall off the engaging portion 23A.
[0017]
(Description of operation)
The operation of the delivery device 12 configured as described above will be described with reference to FIGS. First, in the state where each support member 27, 32, 35, 38 of the delivery means 18 is located at the retracted end and the lifter 9 is located at the descending end, the transfer wheel 1 holding the syringe 2 in the pocket 1a is provided. After intermittent rotation, it temporarily stops at the extraction position B (FIG. 8). These four temporarily stopped syringes 2 are positioned above the contact member 22 of the push-up mechanism 17. At this time, the contact member 22 is positioned at the lower end (FIG. 8).
Then, since the control device 11 recognizes which of the syringes 2 stopped at the extraction position B by the detection signal from the inspection device 8 is the defective syringe 2, the defective syringe. Only the air cylinder 21 located below 2 is operated. As a result, the contact member 22 attached to the air cylinder 21 is raised, so that the contact member 22 contacts the lower end of the defective syringe 2 and pushes it up by a predetermined amount. Therefore, the defective syringe 2 is in a state in which the collar portion 2b and the outer peripheral portion below the adjacent portion are raised above the pocket 1a (FIG. 9).
[0018]
Thereafter, since the air cylinder 41 is operated, the fourth support member 38 is advanced to the advance end position along the guide rail 37 with respect to the third support member 35 (FIGS. 9 and 1). As a result, the grippers 23 that have been positioned on the same straight line so far can be positioned above the four syringes 2 on the transport wheel 1 side.
Next, since the air cylinder 36 is actuated, the support members 35 and 38 and the four grippers 23 in the above-described state are simultaneously advanced toward the conveying wheel 1 by a predetermined amount (FIG. 10). Thereby, the four grippers 23 are positioned above the four syringes 2 on the transport wheel 1 side. At this time, as described above, since the defective syringe 2 has the flange portion 2b and the adjacent lower side portion floating from the pocket 1a of the transport wheel 1, the lower portion of the flange portion 2b of the defective syringe 2 is raised.

Thereafter, since the cylinder mechanism 28 is operated and raised to the rising end position, the support members 27, 32, 35, 38 and the four grippers 23 are also raised. Further, in this process, since the air cylinder 42 above the engaging portion 23A engaged with the defective syringe 2 is operated, the presser portion 23B is lowered. As a result, the flange portion 2b of the defective syringe 2 is supported by the engaging portion 23A and covered by the lowered pressing portion 23B. Therefore, the defective syringe 2 is reliably held by the gripper 23. In this way, only the defective syringe 2 is extracted from the pocket 1a of the transport wheel 1 held by the gripper 23 (FIG. 11).
[0019]
Next, in a state where the cylinder mechanism 28 remains in the raised end position, the air cylinder 41 is retracted to the retracted end, and the air cylinder 36 is retracted. As a result, the four grippers 23 are positioned on the same straight line, and they are positioned above the delivery position C of the discharge chute 13 (FIG. 12).

Further, in conjunction with the cylinder mechanism 28, the support members 27, 32, 35, 38, the grippers 23, and the defective syringe 2 held therein are lowered (FIG. 13). As a result, the defective syringe 2 held by the gripper 23 is inserted between the plate-like members 15A and 15B of the discharge chute 13 and the lower end thereof is engaged with the engaging portion 9a of the lifter 9. Supported (FIG. 13).
Thereafter, since the operation of the air cylinder 42 of the gripper 23 is stopped, the pressing member 23B is lifted and completely separated from the collar portion 2b of the syringe 2 (FIG. 13).
Next, since the air cylinder 33 provided on the first support member 27 is retracted, the four grippers 23 are retracted synchronously, whereby the engaging portion 23A of the gripper 23 is the outer peripheral portion of the defective syringe 2. (Fig. 14). As a result, the defective syringe 2 is delivered from the delivery means 18 to the delivery position C of the delivery chute 13 (FIG. 14).
Thereafter, since the lifter 9 is lowered to the lower end by the cylinder mechanism 19, the lower end portion of the defective syringe 2 is separated from the engaging portion 9a of the lifter 9, while the collar portion 2b is the both plates of the discharge chute 13. 15A and 15B (FIG. 15).
In this state, the cylinder mechanisms 36 and 41 are operated, and each gripper 23 is advanced again to the position adjacent to the extraction position B without interfering with the defective syringe 2 supported by the discharge chute 13.
By repeating the above-described operation, the delivery means 18 is configured to withdraw the defective syringe 2 from the pocket 1a of the transport wheel 1 at the extraction position B and deliver it to the discharge position C of the discharge chute 13.
The defective syringe 2 supported at the discharge position C of the discharge chute 13 is pushed out from the discharge position C to the sliding section D by the pushing member 16 described above.

That is, it is possible to omit the operation of discharging the defective syringe 2 by the worker on site.
Further, as described above, the four grippers 23 provided in the delivery device 12 are located on the concentric circles above the four pockets 1a on the conveyance wheel 1 side on the extraction position B, and on the other hand, the discharge on the discharge chute 13 side. In the position C, it is located on the same straight line. Therefore, the syringe 2 can be delivered from the conveyance wheel 1 that is a rotary conveyance device to the discharge chute 13 that is a linear conveyance device without any problem.
In the above-described embodiment, only the defective syringe 2 is pushed out by the push-up mechanism 17 out of the four syringes 2 stopped at the extraction position B, and has the following configuration. Also good. That is, the four grippers 23 included in the delivery device 12 are configured to be able to advance and retreat independently, and all the four syringes 2 stopped at the extraction position B are pushed up by the push-up mechanism 17, and the four syringes The defective syringe 2 out of the two may be pulled out by the gripper 23 that is advanced and retracted individually.
