Description

TECHNICAL FIELD

The present disclosure relates to a machine for packaging a medical article, and in particular, to a high-speed blister cartoning integrated machine.

BACKGROUND

In pharmaceutical packaging and packaging technological process, and particularly in linkage packaging from blister packaging to cartoning for liquid preparations (prefilled syringes, penicillin bottles, and ampoule bottles), how to realize high-speed integrated linkage operation between the preceding blister packaging machine (for blister forming and packaging) and the following cartoning machine (for blister cartoning) in a relatively compact pharmaceutical packaging workshop has become a technical problem to the current core process in the pharmaceutical packaging industry. According to original solutions, plastic blister supports packaged by a blister packaging machine are conveyed to a hopper of a cartoning machine through a conveyor belt or to a feeding station of the cartoning machine through a conveyor chain. For the former method combined with the conveyor belt and the hopper, the plastic blister supports are conveyed forward by a frictional force of the conveyor belt. In this process, the plastic blister supports have a slipping phenomenon on the conveyor belt. Particularly in the high-speed conveying process, due to the frictional force and inertial slipping, the plastic blister supports cannot accurately enter the feeding region of the hopper in the cartoning machine. Hence, large-scale synchronous linkage integrated packaging cannot be effectively realized. For the latter method using the conveyor chain, the conveyor chain usually uses a synchronous belt as a conveying base material. Stops are equidistantly provided on a surface of the synchronous belt to form the annular conveyor chain. In case of a specification change in the preceding blister packaging, after a production batch and a packaging specification are changed, spacings between the plastic blister supports packaged by the blister packaging machine are not always the same, and the number of trimmed blister plastic supports also changes with an actual size of medicines, such that the whole conveyor chain is to be replaced. Moreover, the conventional conveyor chain using the synchronous belt that is difficult to be replaced needs to be calibrated for its origin in each replacement. This is inconvenient for the large-scale synchronous integrated linkage production in the pharmaceutical packaging and hardly adaptable to the integrated linkage packaging technological process in the whole pharmaceutical industry. CN113023003A discloses a full-automatic pre-filled injector packaging production line which comprises a bubble cap packaging machine and a boxing machine; the bubble cap packaging machine is provided with a feeding station and a bubble cap output station; the boxing machine is provided with a boxing conveying chain used for conveying materials to be boxed, and positioning clamps are evenly distributed on the boxing conveying chain; the full-automatic pre-filled injector packaging production line further comprises a pre-filled injector feeding device which is connected with the feeding station and used for placing pre-filled injectors into empty bubble caps, and a relay device arranged between the bubble cap packaging machine and the boxing machine; and the relay device is used for picking up finished bubble cap plates on the bubble cap output station, adjusting the distance between the finished bubble cap plates and then transferring the finished bubble cap plates to the boxing conveying chain. US2021/268714A1 discloses a molding device including a pitch changing device.

DETAILED DESCRIPTION OF THE EMBODIMENTS

As shown in FIGS. 1-3, a high-speed blister cartoning integrated machine includes blister packaging machine 1 and cartoning machine 5. The blister packaging machine 1 includes blister trimming device 10 and discharging grid conveyor device 11. Packaged blisters C trimmed by the blister trimming device 10 are placed into the discharging grid conveyor device 11 and then conveyed out by the discharging grid conveyor device 11.
The cartoning machine 5 includes feeding grid conveyor device 51. Packaged blisters are placed onto the feeding grid conveyor device 51, and conveyed by the feeding grid conveyor device 51 to a cartoning station of the cartoning machine 5 for cartoning (carton packaging).
The discharging grid conveyor device 11 has a different grid spacing from the feeding grid conveyor device 51. For the sake of matching between the two devices, synchronous spacing-changing conveyor device 3 is provided in front of the discharging grid conveyor device 11. The synchronous spacing-changing conveyor device 3 is provided side by side with the feeding grid conveyor device 51. Blister discharging transfer manipulator 2 for transferring blisters on the discharging grid conveyor device 11 to the synchronous spacing-changing conveyor device 3 is provided above the discharging grid conveyor device 11. The blister discharging transfer manipulator 2 includes discharging vacuum nozzle 20. Blister feeding transfer manipulator 4 for transferring blisters on the synchronous spacing-changing conveyor device 3 to the feeding grid conveyor device 51 is provided above the feeding grid conveyor device 51. The blister feeding transfer manipulator 4 includes feeding vacuum nozzle 40.
The high-speed blister cartoning integrated machine has the following working principle: Blisters are conveyed out from the discharging grid conveyor device 11 of the blister packaging machine 1. The blister discharging transfer manipulator 2 sucks the blisters C on the discharging grid conveyor device 11 through the discharging vacuum nozzle 20, and transfers them to the synchronous spacing-changing conveyor device 3. While moving forward, the synchronous spacing-changing conveyor device 3 changes a spacing between the blisters (as shown in FIG. 7), until the spacing is the same as the spacing of the feeding grid conveyor device 51. The blister feeding transfer manipulator 4 sucks the blisters on the synchronous spacing-changing conveyor device 3 through the feeding vacuum nozzle 40 and transfers them to the feeding grid conveyor device 51. The feeding grid conveyor device 51 transfers the blisters to the cartoning station of the cartoning machine 5 for cartoning. With the synchronous spacing-changing conveyor device 3, the present disclosure can greatly improve the linkage production efficiency between the blister packaging machine 1 and the cartoning machine 5 and solves the problem of hard matching between blister packaging and cartoning in a specification change.
Both the blister packaging machine and the cartoning machine are the prior art (refer to the patent application No. 201520906465.3 ). The blister discharging transfer manipulator is also the prior art (refer to the patent application No. 201910076327.X , in which the structure is the same, but the material to be transferred is different). The blister feeding transfer manipulator is also the prior art (refer to the patent application No. 202120863286.1 ). The high-speed blister cartoning integrated machine is novel for the synchronous spacing-changing conveyor device and the linkage layout using the synchronous spacing-changing conveyor device.
The following descriptions describe the structure and working principle of the synchronous spacing-changing conveyor device 3.
As shown in FIG. 4, the synchronous spacing-changing conveyor device 3 includes base 30. As shown in FIG. 6, first slideway 301 and second slideway 302 are provided side by side on the base 30. A plurality of first sliding seats 311 are slidably provided on the first slideway 301. First tray 321 (the first tray 321 is provided with a placement groove into which a blister can be placed) is provided on each of the first sliding seats 311. A plurality of second sliding seats 312 are slidably provided on the second slideway 302. Second tray 322 (the second tray 321 is provided with a placement groove into which a blister can be placed) is provided on each of the second sliding seats 312. The first sliding seat 311 is connected to a hinge shaft. Two cross-connecting rods 31 are hinged crosswise on the hinge shaft. The second sliding seat 312 is also connected to a hinge shaft. Two cross-connecting rods 31 are hinged crosswise on the hinge shaft. Cross-connecting rods 31 on two adjacent first sliding seat 311 and second sliding seat 312 are hinged crosswise in one-to-one correspondence (to form a scissor-type structure). One of the first sliding seats 311 is connected to first transmission belt 351. The first transmission belt 351 is in transmission connection with first power source 361. One of the second sliding seats 312 is connected to second transmission belt 352. As shown in FIG. 4, the second transmission belt 352 is in transmission connection with second power source 362.
The synchronous spacing-changing conveyor device 3 has the following working principle: As shown in FIG. 7 and FIG. 8, after blisters are placed onto the first tray 321 and the second tray 322, the first power source 361 drives the first transmission belt 351 to rotate. Since one of the first sliding seats 311 is connected to the first transmission belt 351, the first sliding seats 311 move on the first slideway 301. Likewise, the second power source 362 drives the second transmission belt 352 to rotate. Since one of the second sliding seats 312 is connected to the second transmission belt 351, the second sliding seats 312 move on the second slideway 302. The first sliding seats 311 are connected to the second sliding seats 312 through the cross-connecting rods 31, so all of the first sliding seats 311 and all of the second sliding seats 312 move. Meanwhile, by adjusting the outputs of the power sources, a certain difference is kept between a transfer speed of the first transmission belt 351 and a transfer speed of the second transmission belt 351, and thus spacings between two adjacent ones of the first sliding seats 311 and the second sliding seats 312 change equidistantly, as shown in FIG. 8. The blisters have the same spacing as the following feeding grid conveyor device 5. After the blisters on the trays are taken away, the transmission belts move reversely, and the sliding seats are restored quickly for the next receiving. The above process is repeated. With the synchronous spacing-changing conveyor device 3, the preceding discharging grid conveyor device 11 can be matched with the following feeding grid conveyor device 5, no matter how the specification of the discharging grid conveyor device changes.
For the blisters of different specifications, different trays are required. For the convenience of replacement of the trays to place the blisters of different specifications, as shown in FIG. 6, first supporting seat 331 is provided on the first sliding seat 311. The first tray 321 is provided on the first supporting seat 331. First locating pin 371 is provided on the first supporting seat 331. A first locating hole for allowing the first locating pin 371 to insert into is formed in the first tray 321. When the first tray 321 is replaced necessarily, the first locating pin 371 is pulled out, and the first tray 321 is taken down, which is very convenient. Likewise, second supporting seat is provided on the second sliding seat 312. The second tray is provided on the second supporting seat. A second locating pin is provided on the second supporting seat. A second locating hole for allowing the second locating pin to insert into is formed in the second tray. When the second tray is replaced necessarily, the second locating pin is pulled out, and the second tray is taken down, which is very convenient.
To avoid rotation of the trays, first locating fixture 341 is provided on the first supporting seat 331. A first locating groove for allowing the first locating fixture 341 to enter is formed at a bottom of the first tray 321. The first supporting seat 331 is clamped onto the first locating fixture 341 through the first locating groove, thereby preventing the rotation of the first tray 321. Likewise, the second supporting seat is connected to a second locating fixture. A second locating groove for allowing the second locating fixture to enter is formed at a bottom of the second tray 322. The second tray 322 is clamped onto the second locating fixture through the second locating groove, thereby preventing the rotation of the second tray 322.
The discharging grid conveyor device 11 of the blister packaging machine may use a common grid conveyor device. However, the present disclosure provides a novel grid conveyor device. As shown in FIG. 10 and FIG. 11, the discharging grid conveyor device 11 includes conveyor rack A10, grid plate A15, first pushing plates A11, a first pushing plate transmission mechanism, and pushing power source A19. The grid plate A15 is provided with feeding channel A150. The first pushing plates A11 each are provided with pushing portion A110 capable of being located in the feeding channel A150. The first pushing plate transmission mechanism includes first conveyor belt A13. The first pushing plates A11 are connected to the first conveyor belt A13. The first conveyor belt A13 is in transmission connection with the pushing power source A19. During operation, trimmed blisters C fall into the feeding channel A150 of the grid plate A15. The pushing power source A19 drives the first conveyor belt A13 to move. Since the first pushing plates A11 are connected to the first conveyor belt A13, the first conveyor belt A13 drives the first pushing plates A11 to move, and the pushing portions A110 of the first pushing plates A11 push the blisters C to move forward.
For the blisters of different specifications, the grid spacing of the discharging grid conveyor device 11 can also be adjusted as required, so as to realize a most efficient output. The discharging grid conveyor device 11 in the present disclosure further includes second pushing plates A12 and a second pushing plate transmission mechanism. The second pushing plates A12 and the first pushing plates A11 are arranged at intervals. The second pushing plates A12 each are provided with a pushing portion located in the feeding channel A150. The second pushing plate transmission mechanism includes second conveyor belt A14. The second conveyor belt A14 is provided side by side with the first conveyor belt A13. The second pushing plates A12 are connected to the second conveyor belt A14. The second conveyor belt A14 is in transmission connection with the pushing power source A19. The second pushing plate A12 has the same pushing principle as the first pushing plate A11, which is not repeated herein. When the grid spacing is adjusted necessarily, either or both of the first conveyor belt A13 and the second conveyor belt A14 are adjusted to change a spacing between the first pushing plate A11 and the second pushing plate A12, thereby conveying the blisters of the different specifications.
To support the pushing plates, an end of each of the second pushing plates A12 and the first pushing plates A11 is connected to roller A16. Roller walkway A17 for allowing the roller A16 to walk is provided on the conveyor rack A10. While the pushing plates move, the rollers A16 walk on the roller walkway A17 of the conveyor rack A10, thereby supporting the pushing plates and making the pushing plates walk more stably.
As shown in FIG. 9, the discharging vacuum nozzle 20 of the blister discharging transfer manipulator 2 is provided on a rotating power source, such that the blisters from the discharging grid conveyor device 11 to the synchronous spacing-changing conveyor device 3 are rotated by 90°, and the transverse blisters are placed longitudinally to meet requirements on cartoning positions. With the rotating power source, the discharging vacuum nozzle 20 is rotated by 90° in movement. The manipulator is rotated when there are many blisters in a longitudinal direction. In case of a small number of blisters in the longitudinal direction, the manipulator is unnecessarily rotated. In addition, the blister feeding transfer manipulator 4 can track blister suction and placement, such that the synchronous spacing-changing conveyor device 3 and the feeding grid conveyor device 51 realize continuous conveyance to improve the packaging efficiency.
As shown in FIG. 12, the blister trimming device 10 continuously trims blisters on a blister card and places the blisters onto the discharging grid conveyor device 11. The blisters are conveyed forward by the discharging grid conveyor device 11.
The existing blister trimming device includes a convex trimming die, a concave trimming die, and a trimming power source. With the trimming power source, the convex trimming die and the concave trimming die are clamped to continuously trim the blisters from the blister card. The blisters fall onto the grid conveyor device and are continuously conveyed forward by the grid conveyor device. However, due to a certain drop between the blister trimming point and the grid conveyor device, the directly falling blisters may be bounced up, and cannot accurately enter grids of the grid conveyor device to affect subsequent normal operation.
In view of the above problem, the present disclosure provides a novel blister trimming device 10. As shown in FIG. 13 and FIG. 14, the novel blister trimming device 10 includes mounting rack B1, concave trimming die B2, convex trimming die B3, and trimming power source B4. The convex trimming die B3 is provided on the mounting rack B1. The concave trimming die B2 is located below the convex trimming die B3. In order to drive the concave trimming die B2 to move up and down, the concave trimming die B2 is connected to die supporting plate B5. The die supporting plate B5 is connected to a lower end of lifting guide post B6. The lifting guide post B6 is slidably provided on the mounting rack B1. An upper end of the lifting guide post B6 is connected to lifting seat B7. The lifting seat B7 is in transmission connection with the trimming power source B4. With the trimming power source B4, the lifting seat B7 drives the die supporting plate B5 through the lifting guide post B6 to move up and down. The concave trimming die B2 connected to the die supporting plate B5 also moves up and down. The concave trimming die B2 is clamped with the convex trimming die B3 for trimming when moving up. The concave trimming die B2 is split with the convex trimming die B3 when moving down.
As shown in FIG. 15 and FIG. 16, vertical slideway B8 is provided on the mounting rack B1. Sliding plate B9 is slidably provided on the vertical slideway B8. The sliding plate B9 is in transmission connection with blanking power source B10 for driving the sliding plate B9 to move on the vertical slideway B8. With the blanking power source B10, the sliding plate B9 moves up and down. The sliding plate B9 is connected to vacuum absorption die B11 (the vacuum absorption die B11 is the prior art). Vacuum suction rod B12 is provided on the vacuum absorption die B11 (a gas path is provided in the vacuum absorption die B11. The vacuum suction rod B12 is connected to the gas path). The convex trimming die B3 is provided with convex die hole B30 for allowing the vacuum suction rod B12 to pass through (only in this way can a blister be sucked from a front side). The concave trimming die B2 is provided with concave die hole B20 for allowing the convex trimming die B3 to enter and allowing the vacuum suction rod B12 to pass through. The die supporting plate B5 is provided with supporting plate hole B50 for allowing the vacuum suction rod B12 to pass through. As shown in FIG. 18, in response to trimming of the concave trimming die B2 and the convex trimming die B3, the vacuum suction rod B12 sucks the blister. Upon completion of the trimming of the concave trimming die B2 and the convex trimming die B3, the blanking power source B10 drives the sliding plate B9 to move down. In this way, the vacuum suction rod B12 takes along the blister to pass through the concave die hole B20 of the concave trimming die B2 and the supporting plate hole B50 of the die supporting plate B5, and places the blister onto the discharging grid conveyor device 11 thereunder. Since the vacuum suction rod B12 sucks the blister and places it down, the blister can stably enter a grid of the discharging grid conveyor device 11.
For the sake of the accurate die clamping, the convex trimming die B3 is connected to die clamping guide post B34. The concave trimming die B2 is connected to guide sleeve B25. The die clamping guide post B34 is located in the guide sleeve B25. Under the guidance of the die clamping guide post B34, the concave trimming die B2 and the convex trimming die B3 can be clamped accurately. The concave trimming die B2 is further connected to the die supporting plate B5 (the die supporting plate B5 drives the concave trimming die B2 to move up and down). For the concave trimming die B2 to be connected to the die supporting plate B5, and the concave trimming die B2 moves horizontally relative to the die supporting plate B5 (to ensure that the concave trimming die B2 moves up and down along the die clamping guide post B34, a common connection between the concave trimming die B2 and the die supporting plate B5 hardly realizes the accuracy for a mounting position of the concave trimming die B2 and thus the concave trimming die B2 must have a horizontal moving space), lower locking member B21 is provided at one side of the concave trimming die B2, as shown in FIG. 19 and FIG. 20. The lower locking member B21 is provided with a locking groove. A side edge of the concave trimming die B2 and a side edge of the die supporting plate B5 are located in the locking groove of the lower locking member B21 (the lower locking member B21 may be connected to the die supporting plate B5 or the concave trimming die B2 through a bolt. Certainly, the bolt may also be used unnecessarily). By locking the concave trimming die B2 and the die supporting plate B5 with the lower locking member B21, the moving die supporting plate B5 can drive the concave trimming die B2 to move up and down. Meanwhile, the concave trimming die B2 can move slightly in a horizontal direction in the locking groove of the lower locking member B21, which ensures that the concave trimming die B2 is not limited completely in the horizontal direction. Therefore, the concave trimming die B2 has a self-adjusting space when moving along the die clamping guide post B34 up and down.
As shown in FIG. 19, the concave trimming die B2 is connected to the die supporting plate B5. For the sake of quick location of the concave trimming die B2 on the die supporting plate B5, locating member B51 is provided on the die supporting plate B5. A locating groove for allowing the locating member B51 to enter is formed at one side of the concave trimming die B2. When the concave trimming die B2 is placed onto the die supporting plate B5, the locating member B51 may enter the locating groove of the concave trimming die B2. In this way, the concave trimming die B2 is basically determined, and then the lower locking member B21 is locked.
For the convenience of die replacement, the convex trimming die B3 is detachably provided on the mounting rack B1. When the dies are taken out necessarily, the convex trimming die B3 is detached, and the lower locking member B21 is taken down. Therefore, the concave trimming die B2 and the convex trimming die B3 can be taken out together.
In order to take out the dies conveniently, as shown in FIG. 19 and FIG. 20, die taking tool B22 is provided at one side of the convex trimming die B3. The die taking tool B22 includes a die taking plate and a handle. The handle is connected to the die taking plate. The die taking plate may be threadedly connected to the concave trimming die B2 and the convex trimming die B3 through a die taking bolt. When the dies are taken out necessarily, while the unlocking is ensured, the die taking plate is connected to the concave trimming die B2 and the convex trimming die B3 through the bolt, and the handle is pulled. Therefore, the concave trimming die B2 and the convex trimming die B3 can be drawn out together, which is very convenient.
As described above, the convex trimming die B3 is detachably provided on the mounting rack B1. In order to provide the convex trimming die B3 conveniently, horizontal clamping groove B31 is formed in the mounting rack B1. A side edge of the convex trimming die B3 may enter the horizontal clamping groove B31 of the mounting rack B1. The convex trimming die B3 is locked with the mounting rack B1 through a bolt.
