Is mainly made of glass. However, when taking out the drug solution by cutting the ampule neck with an ampule cutter, severe medical treatment, such as cutting a finger or cutting glass chips into the drug solution inside the ampoule and injecting it into blood vessels etc. Defects sometimes occurred. Therefore, in recent years, synthetic resin ampules have begun to be manufactured in place of glass ampules.

[0003] This synthetic resin ampoule does not have the above-mentioned problems that have occurred in glass ampules. In addition, in the production of small synthetic resin molded products, generally, a plurality of molded products are simultaneously molded in consideration of production costs and the like. In this case, a plurality of ampoules made of synthetic resin are formed in a connected state, and then a predetermined amount of a predetermined chemical solution is sealed in each of the ampules, and an ampule is formed in a connected state. After that, a label printed with the chemical component, utility, other necessary items, date of manufacture, and the name of the manufacturer, etc. is attached to each ampoule by an automatic machine, etc., and finally separated one by one from the connecting part and packaged individually And a series of work such as packing.

[0004] Conventionally, there has been no separating device for separating the pieces one by one, so that the worker manually separates the connecting parts to separate them. For this reason, the efficiency is low, and since this separation operation is performed at a time after a short time after the resin molding, the ampule itself is in a warm state.

[0005] However, synthetic resin generally becomes sticky when the temperature is high immediately after molding, so that extra force is required to separate the resin early after molding, and in some cases, a jig such as a cutter knife is used. Is required. In such a case, there is a problem that the ampule is cut or the worst hole is formed with a cutter knife, and the operator is contaminated with the chemical solution.

[0006]

DISCLOSURE OF THE INVENTION The present inventors have made it possible to separate an ampoule from an articulated ampoule group into individual ampules, which has been conventionally performed manually, by an automatic machine.

It is configured to be controlled dynamically. The air cylinders 9 a and 9 b and the actuator 12 are operated by receiving the supply of compressed air from the compressor 22. As a result, the operations of the holding means 6 and the separating means 10 are performed.

Next, a series of operations of the separation apparatus of the present invention will be described. However, the description of the sequence control unit will be minimized so as not to complicate the operation description.

FIG. 1 shows a state in which the connected ampule group 100 has been conveyed to a predetermined position by the conveyor B. The moving means 9 is operated from the state shown in FIG. The pair of left and right air cylinders 9a and 9b of the moving means 9 are operated by receiving compressed air from the compressor 22 to move the pair of vertical substrates 2a and 2b via the push plate 93 in a direction approaching each other. This movement slides on the rail 3.

Then, as shown in FIG.
The plurality of gripping members 61 to 65 of the gripping means 6 mounted on a and 2b move from the non-grip position to the grip position. That is, the gripping members 61 to 65 approach the ampoule group 100 and grip (hold) the ampoule group 100 from the left and right.

Next, the separating means 10 is operated with the gripping state shown in FIG. Compressed air is supplied from the compressor 22 to the pair of actuators 12 of the separating means 10 to move the translation rod 13. This movement of the linear motion rod 13 moves the other end (fifth) gripping member 65 in a direction away from the fourth gripping member 64 via the operating rod 14 as shown in FIG. The moving distance is about 3 to 5 mm away from the fourth gripping member 64.
This moving distance corresponds to the axial dimension of the small diameter portion 15b of the stepped pin 15.

By the movement of the gripping member 65, the ampule A gripped by the gripping member 65 is separated from the connecting portion 101 with the adjacent ampule. It is separated into so-called single ampules. At this time, as shown in FIG. 6B, the movement of the gripping member 65 causes the fifth stepped pin 15 to move.
Abuts against the joint plate 17 of the gripping member 65. Since the linear motion rod 13 continues to move,
The fifth stepped pin 15 connects the fourth holding member 64 to the fifth
It is moved in the direction of the second holding member 65.

As a result, immediately after the ampule held by the fifth holding member 65 is separated, the ampule held by the fourth holding member 64 is separated from the other ampules. In this way, the stepped pin 15 sequentially moves the gripping member of the preceding stage with a time delay, and as a result, the second ampule is sequentially separated from the fifth ampule. FIG. 8 shows the state immediately after the separation.

FIG. 8 shows a state immediately after the ampoule group 100 connected in five pieces is separated into a single ampule.
The compressed air of the actuator 12 is discharged. Then, the linear motion rod 13 is retracted, and the second to fifth gripping members 6 are moved.
2 to 65 approach the first gripping member 61. The position of the gripping member is the same as in FIG.

Thereafter, the compressed air of the air cylinders 9a and 9b is similarly discharged, the operation of the air cylinders 9a and 9b is stopped, and the holding members 61 to 65 are retracted to the non-holding position so as to be separated from the ampule. . The position of the gripping member is the same as in FIG. As a result, the gripping member releases the individually separated ampules A onto the conveyor B.

Thereafter, the conveyer B is moved and the separated ampule A is carried out to the next step, that is, the packaging or boxing step. At the same time, the next group of ampules is carried in and stopped at a predetermined position.

The above is a series of separation operations, all of which are controlled by the sequence control unit 20. That is, the conveyor B is operated to convey the ampoule group 100 to a predetermined position → the conveyor is stopped → the moving means 9 is operated → the gripper 6 approaches and the ampule is gripped → the separating means 10 is operated in the gripped state →
Each of the gripping members 65 to 62 sequentially moves in a direction away from the gripping member 61 at one end → separate the ampule individually → approach each gripping member to the gripping member at one end → move the gripping means to the non-grip position → move the ampoule. A series of separation operations of releasing them on a conveyor was performed, and the time for one cycle was several seconds (2
Seconds to 6 seconds), and the time can be appropriately set according to the size and type of the molded article to be separated.

While the embodiment including the operation of the present invention has been described above, the present invention can be implemented in other modes. For example, instead of making the distal end portion of the gripping member, that is, the end face shape that grips the ampule into a semicircular shape that completely wraps the ampule, as shown in FIGS. End surface 67 of one gripping member 66
May be formed in a curved surface larger than that of the outer shape of the ampule or in a substantially straight line. Further, in addition to the one shown in FIG. 12, the grip end surface of the grip member may be shaped to match the outer shape of the molded product to be gripped.

Although the gripping member is made of a synthetic resin material so as not to damage the ampule, aluminum or stainless steel material may be used, and felt or cloth may be adhered to the end surface to be gripped. A flexible member may be used depending on the type and size of the product.

FIG. 13 shows another embodiment of the present invention in which the above-described separating device K is attached to a robot arm. That is, the separating device K is incorporated in the arm 80 that can be handled by the robot.

By operating the arm 80 of the robot, the separating device K is moved to a position where the gripping member 82 can grip the ampule group 100 on the carry-in conveyor 81. Then, temporarily stop the operation of the robot arm 80 at that position,
Thereafter, the separation device K sequentially executes the above-described series of separation operations.

When the separating operation is completed, the arm 80 is moved and the ampule A is placed on the carry-out conveyor 83 which is separated from the carry-in conveyor 81 while holding the ampule with the grasping member 82. In this state, a series of steps of stopping the operation of the arm 80, operating the separating device K, moving the holding member 82 to the non-holding position, and releasing the ampule onto the unloading conveyor 83 are performed.

The separation device K is incorporated in this robot, and the operation of the separation device is linked to the operation of the robot, so that the separation device K can be installed without being restricted by the installation place. Further, if the operation of the robot and the operation of the separation device K are controlled by a single control device, more reliable sequence control can be performed.

Although the present invention has been described in various ways, the present invention can be embodied in variously modified, modified, and modified forms based on the knowledge of those skilled in the art without departing from the spirit thereof. For example, after the gripping means 6 grips the ampoule group 100, the gripping means 6 is slightly lifted to separate the ampule groups from the conveyor B so that they are separated from each other. The ampoule may be lowered to a position and placed on a conveyor.

Also for the actuator 12, mechanical energy obtained by converting fluid energy made of insulating oil may be used instead of the compressed air flow. Alternatively, mechanical energy obtained by converting electric energy via a solenoid, a motor, or the like can be used.

Furthermore, in the present invention, a container for enclosing a medical liquid such as an injection solution as a synthetic resin molded product to be separated is described in one embodiment, but the present invention is not limited to this. For example,
Liquid fertilizer cartridges with gardening liquid fertilizer sealed in a synthetic resin container, hollow cuppy dolls blow-molded with synthetic resin, synthetic resin toys manufactured by extrusion or injection molding, etc., and daily necessities Applied.

As a result, a general-purpose resin such as a polyester-based resin, a polyamide-based resin, a polyacrylic acid-based resin, and a polyvinyl alcohol-based resin can be used as the material of the synthetic resin molded product in addition to the above.

Further, it is desirable that the resin ampule in which the medicinal liquid is sealed has a transparency higher than a level at which the liquid medicine inside can be confirmed. The ampoule may be formed into a single layer or a multilayer. In the case of a multilayer, it is desirable that the innermost layer is a resin layer that does not affect the drug and does not generate eluted substances.
