Description

Technical Field

[0001] The present invention relates to the field of pharmaceutical packaging machinery, and particularly to a pushing device of a blister plate cartoning machine. Background Art

[0002] A blister plate cartoning machine is a device for loading a blister plate (such as a capsule medicine plate) and a paper instruction manual into a medicine box. For example, the applicant applied for a utility model patent named "A medicine plate pushing rod mechanism of a blister cartoning machine" in 2015 (Publication No. CN 205098540).

[0026] Such as Figures 1-5As shown in the figure, this pusher device of the blister packing machine includes a chain 1, sprockets (not shown), an annular push plate guide rail 4, an annular paper push guide rail, and a number of pusher units 2. Each pusher unit 2 includes a pusher seat 20, a push plate assembly 21, and a paper push assembly 22. The push plate assembly 21 and the paper push assembly 22 are both installed on the pusher seat 20, and the pusher seat 20 is connected to the chain 1. The chain 1 is wound around the sprockets. Through the transmission of the main power source, the sprockets drive the chain 1 to rotate, and the chain 1 drives the pusher units 2 to perform circular motion.

[0027] In order to facilitate the adjustment of the height of the push plate assembly 21, the present invention is provided with a guide groove frame 5 on the periphery of the annular push plate guide rail 4, as shown in Figure 1 and Figure 2 As shown, the guide groove frame 5 is provided with an annular paper push guide groove 52 and an annular lifting guide groove 53. As Figure 8 shown, the guide groove frame 5 is assembled by an upper guide groove frame 50 and a lower guide groove frame 51, and the upper guide groove frame 50 is installed on the lower guide groove frame 51 in a lift-adjustable manner. The upper guide groove frame 50 has an upper section 521 of the annular paper push guide groove and an upper section 531 of the annular lifting guide groove, while the lower guide groove frame 51 has a lower section 522 of the annular paper push guide groove and a lower section 532 of the annular lifting guide groove. The upper section 521 of the annular paper push guide groove and the lower section 522 of the annular paper push guide groove can be extended and connected, and the upper section 531 of the annular lifting guide groove and the lower section 532 of the annular lifting guide groove can be extended and connected: that is, when the upper guide groove frame 50 is lifted and adjusted, the distance between the upper section 521 of the annular paper push guide groove and the lower section 522 of the annular paper push guide groove changes, but the two still form a closed loop, and the same is true for the upper section 531 of the annular lifting guide groove and the lower section 532 of the annular lifting guide groove.

[0028] After adopting the above guide groove frame 5 structure, in order to enable the paper push assembly 22 to adapt to this guide groove frame 5, the structure of the pusher unit 2 also needs to be improved accordingly. The specific improvements are as follows: As Figure 6 shown, a lifting guide rail 24 is installed on the pusher seat 20. As Figure 7 shown, a positioning slider 25 is slidably provided on the lifting guide rail 24. A lifting roller 26 and a positioning guide groove 27 are installed on the positioning slider 25. The lifting roller 26 is arranged in the annular lifting guide groove 53; the paper push assembly 22 includes a paper push board 220 and a paper push rod 221. One end of the paper push rod 221 is connected to the paper push board 220, and the other end of the paper push rod 221 is connected with a paper push roller 222. The paper push rod 221 is arranged in the positioning guide groove 27, and the positioning guide groove 27 plays a guiding role for the paper push rod 221, and the paper push roller 222 is arranged in the annular paper push guide groove 52.

[0029] The height adjustment principle of the push paper board 220 is as follows: when the height of the medicine board increases, the height of the push paper board 220 also increases accordingly. When adjusting, the upper guide slot frame 50 is raised, and the annular paper push guide slot upper section 521 and the annular lifting guide slot upper section 531 are raised at the same time. Since the lifting roller 26 is in the annular lifting guide slot 53, the positioning slider 25 moves and rises on the lifting guide rail 24, and the positioning guide slot 27 is also raised at the same time. Since the paper push roller 222 is arranged in the annular paper push guide slot 52, the paper push guide rod 221 and the push paper board 220 are also raised at the same time, so that the paper push guide rod 221 is still in the positioning guide slot 27, and the push paper board 220 can adapt to the height of the medicine board after being raised. In this way, it is very simple to adjust the height of the push paper board 220, as long as the height of the upper guide slot frame 50 is adjusted, thereby reducing the difficulty of adjusting the equipment after changing the specifications of the medicine board and improving production efficiency.

[0030] The extendable connection between the upper section 521 of the annular paper pushing guide groove and the lower section 522 of the annular paper pushing guide groove can adopt a variety of structures, such as a stretchable extension guide groove, which is used to connect the upper and lower sections. The present invention provides a more convenient connection method: Figure 8 As shown, the end of the annular paper pushing guide groove upper section 521 has a vertical guide groove extension 54, and the end of the annular paper pushing guide groove lower section 522 has a vertical connection adjustment groove 55, and the guide groove extension 54 is arranged in the connection adjustment groove 55 in a manner that it can be raised and lowered. When the height of the upper guide groove frame 50 is adjusted, the guide groove extension 54 on the upper guide groove frame 50 moves vertically up and down in the connection adjustment groove 55 on the lower guide groove frame 51, while the annular paper pushing guide groove 52 is still a closed guide groove.

[0031] Similarly, the extendable connection between the upper section 531 of the annular lifting guide groove and the lower section 532 of the annular lifting guide groove can adopt a variety of structures. Since the annular lifting guide groove 53 is slotted along the horizontal direction, an extension block that can move up and down can be used on the side to connect the upper and lower sections through the extension block; the present invention provides a more convenient connection method: Figure 8 and Figure 9 As shown, the end of the annular lifting guide groove upper section 531 has a vertical upper guide groove side wall 533, and the end of the annular lifting guide groove lower section 532 has a vertical lower guide groove side wall 534, and the lower guide groove side wall 534 is aligned with the upper guide groove side wall 533. When the height of the upper guide groove frame 50 is adjusted, although the upper guide groove side wall 533 on the upper guide groove frame 50 and the lower guide groove side wall 534 on the lower guide groove frame 51 are changed in vertical distance, the two are still attached together, and the lifting roller can still be on the upper guide groove side wall 533 or the lower guide groove side wall 534, that is, the annular lifting guide groove 53 is still a closed guide groove.

[0032] In order to adjust the position of the upper guide groove frame 50 more smoothly, the present invention installs a lifting slider seat 511 on the lower guide groove frame 51. A linear guide rail 501 is installed on the upper guide groove frame 50, and the lifting slider seat 511 is slidably arranged on the linear guide rail 501. An adjusting screw 58 is also installed on the lower guide groove frame 51, and the adjusting screw 58 is threadedly connected to the upper guide groove frame 50. When it is necessary to adjust the position of the upper guide groove frame 50, as long as the adjusting screw 58 is rotated (either manually or by a motor), the upper guide groove frame 50 can move up and down through the linear guide rail 501, thereby achieving smooth adjustment.

[0033] Of course, the push plate assembly 21 includes a push plate head 210, push plate rollers 212 and a push plate slider 211. As Figure 6 shown, both the push plate rollers 212 and the push plate head 210 are connected to the push plate slider 211. The push plate rollers 212 are located within the annular push plate guide rail 4. A positioning guide rail 28 is provided on the pusher seat 20, and the push plate slider 211 is slidably arranged on the positioning guide rail 28. As the pusher seat 20 makes a circular motion, the push plate rollers 212 move on the annular push plate guide rail 4. Under the guidance of the annular push plate guide rail 4, the push plate slider 211 moves on the positioning guide rail 28, so that the push plate head 210 can perform the action of pushing the medicine plate.

[0034] As Figure 5 shown in Figure 10 Generally, the push plate rollers move along the path of the annular push plate guide rail 4. When the push plate rollers 212 move along this path, the push plate head 210 can normally push out the medicine plate. However, sometimes there is a problem with the placement of the medicine plate, resulting in no medicine plate in a certain grid within the medicine plate conveying grille. At this time, the push plate head 210 does not need to push out. Of course, the push plate head 210 can also push out. However, since the process of the push plate head 210 pushing out is the process of the push plate rollers 212 moving on the ramp, which will affect the roller life. To solve this problem, a push plate protection guide groove 40 is provided on one side of the annular push plate guide rail 4. Both ends of the push plate protection guide groove 40 are connected to the annular push plate guide rail 4. A push plate track-changing assembly is provided at the connection between the upper end of the push plate protection guide groove 40 and the annular push plate guide rail 4. The push plate track-changing assembly includes a push plate track-changing turnout 41 and a push plate track-changing power source for driving the rotation of the push plate track-changing turnout 41. When the system detects that there is no medicine plate in a certain grid, the push plate track-changing power source controls the rotation of the push plate track-changing turnout 41. In this way, a corresponding push plate roller 210 no longer enters the annular push plate guide rail 4, but enters the push plate protection guide groove 40. Since there is no ramp in the push plate protection guide groove 40, it will not affect the push plate roller 210, thereby increasing the life of parts such as the rollers.

[0035] Similarly, in order to extend the life of the paper-pushing rollers, a paper-pushing protection guide groove 59 is provided on one side of the annular paper-pushing guide groove 52, as Figure 12As shown in the figure, both ends of the paper pushing protection guide groove 59 are connected to the annular paper pushing guide groove 52. A paper pushing track changing assembly is provided at the upper end connection of the paper pushing protection guide groove 59 and the annular paper pushing guide groove 52. As Figure 11 shown, the paper pushing track changing assembly includes a paper pushing track changing turnout 590 and a paper pushing track changing power source for driving the rotation of the paper pushing track changing turnout 590. Its principle is the same as that of the track change of the above-mentioned push plate roller and will not be elaborated here.
