Description

Technical Field

[0001] This invention relates to the field of pharmaceutical packaging, and more specifically to an automatic blister pack conveying device. Background Technology

[0002] In the pharmaceutical packaging industry, blister packing is a crucial step in drug production. With the increasing scale and automation of drug production, higher demands are placed on the efficiency and stability of blister pack delivery. Among these, sizes ≤27... The small size and lightweight 66mm blister packs are prone to various problems in the conveying process of traditional automatic cartoning processes due to their small size and light weight. This makes it difficult to achieve smooth automatic cartoning, restricts the improvement of production efficiency, and makes it difficult to meet the production needs of large-scale, high-speed cartoning.

[0003] Chinese utility model patent CN223891352U discloses an automatic blister pack feeding mechanism, comprising a feeding bin formed by four movable panels and a base, with a hollowed-out groove in the side wall; an upstream conveying device for conveying blister packs to the feeding bin; an automatic feeding device for feeding blister packs from the feeding bin into a guide groove of the downstream conveying device; and a first photoelectric sensor installed outside the feeding bin to detect the position and quantity of blister packs in the feeding bin through the hollowed-out groove. The automatic feeding mechanism has a transparent wall panel on the hollowed-out groove of the feeding bin to guide the blister packs from the upstream conveying device into the feeding bin and neatly stack them on the automatic feeding device.

[0004] The above has the following drawbacks: The feeding hopper is vertically downward. For small, lightweight blister packs, when they fall into the feeding hopper from the upstream conveyor, their trajectory is parabolic due to inertia. At this time, the blister packs will hit the inner wall of the feeding hopper. Because the blister packs are small and lightweight, they are very easy to flip inside the feeding hopper. In addition, the height difference between the upstream and downstream conveyor devices is large, and the feeding hopper is relatively high, which will further aggravate the flipping of the blister packs in the air. As a result, the blister packs cannot be neatly stacked at the bottom of the feeding hopper, requiring repeated manual sorting, which seriously affects the efficiency of subsequent boxing. Summary of the Invention

[0005] The purpose of this invention is to overcome the above-mentioned technical deficiencies and propose an automatic blister pack separating and conveying device to solve the technical problem that small-sized, lightweight blister packs are prone to overturning in the hopper during the falling process in the prior art.

[0006] To achieve the above-mentioned technical objectives, the present invention provides an automatic blister pack separating and conveying device, including a frame; A primary plate conveying mechanism is provided on the frame and includes a primary conveyor belt, a primary hopper, and a primary plate separating assembly. The outlet of the primary conveyor belt is connected to the inlet of the primary hopper, and the primary plate separating assembly is connected inside the primary hopper to convey the stacked medicine plates inside the primary hopper out of the primary hopper one by one. A secondary conveying mechanism, located on the frame, includes a secondary conveyor belt, a secondary hopper, and a secondary blister packing assembly. The inlet of the secondary conveyor belt communicates with the outlet of the primary hopper, and the outlet of the secondary conveyor belt communicates with the inlet of the secondary hopper. The secondary hopper is shaped like an inclined arc. The secondary blister packing assembly is connected inside the secondary hopper and is used to group and deliver stacked blister packs from the secondary hopper out of the secondary hopper. A tray stacking mechanism is provided on the frame, and the outlet of the secondary hopper is connected to the inlet of the tray stacking mechanism. The tray stacking mechanism is used to convey groups of medicine trays.

[0007] In some embodiments, the primary conveying mechanism further includes a guide plate assembly, which includes a first guide plate and a second guide plate. The first guide plate and the second guide plate are both connected to the frame. The first guide plate and the second guide plate are located on both sides of the primary conveyor belt, and the distance between the first guide plate and the second guide plate is adapted to the width of the blister pack.

[0008] In some embodiments, the inlet of the second guide plate is bent away from the first guide plate.

[0009] In some embodiments, the primary conveying mechanism further includes a primary pressure plate assembly, which includes rollers, a pressure plate belt, and a first motor. Two rollers are rotatably connected to the frame, the first motor is mounted on the frame, and the output shaft of the first motor is connected to one of the rollers. The pressure plate belt is wound around the two rollers and is located above the primary conveyor belt. The pressure plate belt is located between the first guide plate and the second guide plate, and the distance between the pressure plate belt and the primary conveyor belt is adapted to the thickness of the blister pack.

[0010] In some embodiments, the conveying direction of the primary conveyor belt is the same as that of the pressure plate belt.

[0011] In some embodiments, the primary plate-separating assembly includes a first rotating plate and a second motor. Both second motors are mounted on the frame. The two first rotating plates are respectively connected to the output shafts of the two second motors. Each of the two first rotating plates is provided with a first clearance opening. When the two first clearance openings are facing each other, the medicine plates in the primary hopper fall onto the secondary conveyor belt. When the two first clearance openings are facing away from each other, the medicine plates in the primary hopper fall onto the two first rotating plates.

[0012] In some embodiments, the secondary conveying mechanism further includes a secondary pressure plate assembly, the secondary pressure plate assembly including a pressure plate cover, the pressure plate cover being connected to the frame, the pressure plate cover being located above the secondary conveyor belt, and the distance between the pressure plate cover and the secondary conveyor belt being adapted to the thickness of the blister pack.

[0013] In some embodiments, the inlet of the pressure plate cover is bent upwards.

[0014] In some embodiments, the secondary plate-separating assembly includes a second rotating plate, a third motor, a feed channel, a pusher plate, and a cylinder. Two third motors are mounted on the frame, and two second rotating plates are respectively connected to the output shafts of the two third motors. Each of the two second rotating plates has a second clearance opening. The feed channel is connected to the frame, and the outlet of the secondary hopper communicates with the inlet of the feed channel. The outlet of the feed channel communicates with the inlet of the plate-separating mechanism. The cylinder is mounted on the frame, and the pusher plate is connected to the piston rod of the cylinder. The pusher plate is located within the feed channel. When the two second clearance openings are opposite each other, the medicine plates in the secondary hopper fall into the feed channel, and the pusher plate pushes the grouped medicine plates to the plate-separating mechanism. When the two second clearance openings are opposite each other, the medicine plates in the secondary hopper fall onto the two second rotating plates.

[0015] In some embodiments, the blister packing mechanism includes a three-stage conveyor belt and partitions, with a plurality of partitions spaced apart along the length of the three-stage conveyor belt, and the spacing between adjacent partitions being adapted to the width of the blister pack.

[0016] Compared with the prior art, the beneficial effects of the present invention include: By using a two-stage conveying mechanism consisting of a primary conveying mechanism and a secondary conveying mechanism, the overall falling height of the medicine plate is divided into two small falls, which significantly reduces the height difference of a single fall and the flight distance in the air, thereby reducing the risk of medicine plate flipping and loss of attitude from the root. The inclined, arc-shaped secondary hopper provides a smooth guide for the blister packs, changing the parabolic trajectory of the traditional vertical fall and preventing the blister packs from hitting the hopper wall. It is especially suitable for small-sized, lightweight blister packs, ensuring stable falling posture. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0020] This invention provides an automatic blister pack separating and conveying device, the structure of which is as follows: Figure 1 - Figure 10 As shown, it includes rack 1; The primary conveying mechanism 2 is located on the frame 1 and includes a primary conveyor belt 21, a primary hopper 22 and a primary separating assembly 23. The outlet of the primary conveyor belt 21 is connected to the inlet of the primary hopper 22. The primary separating assembly 23 is connected to the primary hopper 22 and is used to send the stacked medicine plates in the primary hopper 22 out of the primary hopper 22 one by one. A secondary conveying mechanism 3, located on the frame 1, includes a secondary conveyor belt 31, a secondary hopper 32, and a secondary blister packing assembly 33. The inlet of the secondary conveyor belt 31 communicates with the outlet of the primary hopper 22, and the outlet of the secondary conveyor belt 31 communicates with the inlet of the secondary hopper 32. The secondary hopper 32 is in the shape of an inclined arc. The secondary blister packing assembly 33 is connected inside the secondary hopper 32 and is used to convey the stacked blister packs inside the secondary hopper 32 in groups out of the secondary hopper 32. A tray arrangement mechanism 4 is provided on the frame 1. The outlet of the secondary silo 32 is connected to the inlet of the tray arrangement mechanism 4. The tray arrangement mechanism 4 is used to convey groups of medicine trays.

[0021] In use, the blister packs first enter the primary hopper 22 via the primary conveyor belt 21. The primary blister pack separation assembly 23 separates and sends out the stacked blister packs one by one, completing the first blister pack drop. Then, the blister packs enter the secondary conveyor belt 31 and are transported to the inclined arc-shaped secondary hopper 32 for the second drop. Through the two-stage segmented conveying of the primary blister pack conveying mechanism 2 and the secondary blister pack conveying mechanism 3, the original large drop height is split into two small drops, which greatly reduces the height of a single drop. At the same time, the inclined arc-shaped secondary hopper 32 guides and buffers the blister packs to prevent them from overturning due to inertial impact on the hopper wall, so that the blister packs are stacked stably and orderly. Then, the secondary blister pack separation assembly 33 sends them in groups to the stacking mechanism 4 to ensure neat and stable conveying.

[0022] In this invention, the overall falling height of the medicine plate is divided into two small falls by two-stage conveying mechanisms 2 and 3, which significantly reduces the height difference of a single fall and the flight distance in the air, thereby reducing the risk of medicine plate flipping and loss of attitude from the root.

[0023] The inclined, arc-shaped secondary hopper provides smooth guidance for 32 pairs of blister packs, changing the parabolic trajectory of the traditional vertical fall and preventing the blister packs from hitting the hopper wall. It is especially suitable for small-sized, lightweight blister packs, ensuring stable falling posture.

[0024] To ensure that the blister packs on the primary conveyor belt 21 enter the primary hopper 22 one by one, please refer to... Figure 2 In a preferred embodiment, the primary conveying mechanism 2 further includes a guide plate assembly 24, which includes a first guide plate 241 and a second guide plate 242. The first guide plate 241 and the second guide plate 242 are both connected to the frame 1. The first guide plate 241 and the second guide plate 242 are respectively located on both sides of the primary conveyor belt 21, and the distance between the first guide plate 241 and the second guide plate 242 is adapted to the width of the medicine plate.

[0025] In use, the guide plate assembly 24 consists of a first guide plate 241 and a second guide plate 242, both of which are fixedly connected to the frame 1 and distributed on both sides of the primary conveyor belt 21. The spacing between the first guide plate 241 and the second guide plate 242 is precisely adapted to the width of the small-sized lightweight blister pack, forming a guide channel that matches the width of the blister pack. When the blister pack is conveyed towards the primary hopper 22 by the primary conveyor belt 21, the first guide plate 241 and the second guide plate 242 on both sides play a lateral limiting and guiding role for the blister pack, which can effectively limit the blister pack from shifting left or right or tilting during the conveying process, and ensure that the blister pack is always conveyed smoothly along the center line of the primary conveyor belt 21.

[0026] To ensure the blister packs on the primary conveyor belt 21 smoothly enter between the first guide plate 241 and the second guide plate 242, please refer to... Figure 2 In a preferred embodiment, the inlet of the second guide plate 242 is bent away from the first guide plate 241.

[0027] When in use, the inlet of the second guide plate 242 bends away from the first guide plate 241, so that the inlet end of the primary conveyor belt 21 forms a funnel-shaped guide structure that is wider on the outside and narrower on the inside. This structure guides, centers, and corrects deviations when the medicine blister enters the guide channel. Even if the medicine blister is slightly deviated or tilted during the upstream transport process, it can automatically correct its posture and smoothly enter the guide channel under the guidance of the funnel-shaped bending structure.

[0028] To further limit the movement of the medicine blister pack, please refer to... Figure 3 In a preferred embodiment, the primary conveying mechanism 2 further includes a primary pressure plate assembly 25, which includes rollers 251, a pressure plate belt 252, and a first motor 253. Two rollers 251 are rotatably connected to the frame 1, and the first motor 253 is mounted on the frame 1. The output shaft of the first motor 253 is connected to one of the rollers 251. The pressure plate belt 252 is wound around the two rollers 251 and is located above the primary conveyor belt 21. The pressure plate belt 252 is located between the first guide plate 241 and the second guide plate 242, and the distance between the pressure plate belt 252 and the primary conveyor belt 21 is adapted to the thickness of the blister pack.

[0029] In use, the primary pressure plate assembly 25 consists of rollers 251, a pressure plate belt 252, and a first motor 253. The two rollers 251 are rotatably connected to the frame 1 and are located above the primary conveyor belt 21, within the guide channel formed by the first guide plate 241 and the second guide plate 242. The first motor 253 is fixedly installed on the frame 1, and its output shaft is connected to one of the rollers 251 for transmission, providing power for the movement of the pressure plate belt 252. The pressure plate belt 252 is wound around the two rollers 251 to form a pressing and conveying structure that corresponds vertically to and is arranged parallel to the primary conveyor belt 21. The distance between the pressure plate belt 252 and the primary conveyor belt 21 is precisely adapted to the thickness of the small-sized lightweight medicine plate.

[0030] During operation, the first motor 253 starts, driving the connected roller 251 to rotate, which in turn drives the pressure belt 252 to rotate synchronously with the roller 251. After the blister pack is corrected in posture by the flared structure at the inlet of the second guide plate 242, it enters the guide channel between the first guide plate 241 and the second guide plate 242, and is located between the primary conveyor belt 21 and the pressure belt 252. At this time, the pressure belt 252 applies a downward flexible clamping force to the blister pack during rotation, which, together with the upward supporting force of the primary conveyor belt 21, stably clamps the blister pack between the two. This not only limits the up-and-down jumping and flipping of the blister pack due to its lightweight characteristics during transportation, but also avoids damage to the blister pack caused by rigid clamping.

[0031] With the combined effect of the lateral limiting of the guide channel and the upper and lower clamping of the pressure plate belt 252, the medicine plate can always maintain a flat posture and be smoothly and accurately transported to the primary silo 22 along the center line of the primary conveyor belt 21.

[0032] To achieve synchronous clamping and conveying of the blister pack in the same direction, please refer to... Figure 3 In a preferred embodiment, the conveying direction of the primary conveyor belt 21 is the same as the conveying direction of the pressure plate belt 252.

[0033] When in use, the conveying direction of the primary conveyor belt 21 is the same as that of the pressure plate belt 252. The two form synchronous clamping and conveying in the same direction, generating a consistent forward conveying force on the blister packs, avoiding shearing, jamming, and scraping of the blister packs due to opposite directions of movement; it can ensure that the blister packs are smoothly conveyed forward under the clamping state.

[0034] To ensure that the blister packs in the primary silo 22 fall one by one onto the secondary conveyor belt 31, please refer to... Figure 4 and Figure 5In a preferred embodiment, the primary plate-separating assembly 23 includes a first rotating plate 231 and a second motor 232. Both second motors 232 are mounted on the frame 1. The two first rotating plates 231 are respectively connected to the output shafts of the two second motors 232. Each of the two first rotating plates 231 is provided with a first clearance opening 233. When the two first clearance openings 233 are facing each other, the medicine plates in the primary hopper 22 fall onto the secondary conveyor belt 31. When the two first clearance openings 233 are facing away from each other, the medicine plates in the primary hopper 22 fall onto the two first rotating plates 231.

[0035] In operation, two second motors 232 are mounted on the frame 1, each with its output shaft driving a first rotating plate 231 to rotate. The two first rotating plates 231 are symmetrically arranged below the primary hopper 22 to support and release blister packs. When the first clearance openings 233 on the two first rotating plates 231 face each other, a channel is formed between the two plates, allowing the blister packs in the primary hopper 22 to pass smoothly through the clearance openings and fall onto the secondary conveyor belt 31. When the first clearance openings 233 on the two first rotating plates 231 face away from each other, the solid parts of the rotating plates face each other, forming a supporting plane that supports the blister packs falling from the primary hopper 22, thus achieving temporary storage and stopping of the blister packs. By driving the first rotating plates 231 to rotate via the second motors 232, the relative and opposite states of the first clearance openings 233 are controlled, enabling the blister packs to fall one by one in a controllable and orderly manner.

[0036] To achieve the limiting of the medicine plate on the secondary conveyor belt 31, please refer to... Figure 6 In a preferred embodiment, the secondary conveying mechanism 3 further includes a secondary pressure plate assembly 34, which includes a pressure plate cover 341. The pressure plate cover 341 is connected to the frame 1 and is located above the secondary conveyor belt 31. The distance between the pressure plate cover 341 and the secondary conveyor belt 31 is adapted to the thickness of the blister pack.

[0037] In use, the pressure plate cover 341 is fixedly connected to the frame 1 and located above the secondary conveyor belt 31. The distance between the pressure plate cover 341 and the secondary conveyor belt 31 is adapted to the thickness of the blister pack, forming a conveying channel with upper and lower limits. After the blister pack falls from the primary blister pack assembly 23 onto the secondary conveyor belt 31, it is conveyed forward under the drive of the secondary conveyor belt 31. The pressure plate cover 341 limits and constrains the blister pack from above, preventing it from jumping, curling, or flipping due to its light weight and high speed during conveying, thus keeping the blister pack flat and stable while being conveyed forward.

[0038] To achieve the limiting of the medicine blister pack, please refer to... Figure 6 In a preferred embodiment, the inlet of the pressure plate cover 341 is bent upward.

[0039] When in use, the inlet of the pressure plate cover 341 is bent upward, so that the feed end of the secondary conveyor belt 31 forms a funnel-shaped guide structure that is wider at the top and narrower at the bottom. This can guide, straighten, and transition the medicine blister packs entering below the pressure plate cover 341. Even if the medicine blister packs have slight tilting, warping, or height deviation when falling from the primary plate-separating assembly 23, they can automatically correct their posture and smoothly enter the conveying channel under the guidance of the bent inlet.

[0040] To ensure that the blister packs in the secondary silo 32 are grouped and fed into the stacking mechanism 4, please refer to... Figure 7 , Figure 8 as well as Figure 9 In a preferred embodiment, the secondary plate assembly 33 includes a second rotating plate 331, a third motor 332, a material channel 333, a pusher plate 334, and a cylinder 335. Both third motors 332 are mounted on the frame 1. The two second rotating plates 331 are respectively connected to the output shafts of the two third motors 332. Each of the two second rotating plates 331 is provided with a second clearance opening 336. The material channel 333 is connected to the frame 1, and the outlet of the secondary hopper 32 communicates with the inlet of the material channel 333. The outlet of the material channel 333 is connected to the inlet of the plate-laying mechanism 4. The cylinder 335 is installed on the frame 1. The push plate 334 is connected to the piston rod of the cylinder 335. The push plate 334 is located in the material channel 333. When the two second clearance openings 336 are opposite to each other, the medicine plates in the secondary silo 32 fall into the material channel 333. The push plate 334 pushes the group of medicine plates to the plate-laying mechanism 4. When the two second clearance openings 336 are opposite to each other, the medicine plates in the secondary silo 32 fall onto the two second rotating plates 331.

[0041] In operation, two third motors 332 are fixedly mounted on the frame 1, and their output shafts drive the corresponding second rotating plates 331 to rotate. The two second rotating plates 331 are symmetrically arranged below the secondary silo 32 to support and release the blister packs. When the second clearance openings 336 on the two second rotating plates 331 face away from each other, the solid parts of the rotating plates are opposite each other, forming a supporting plane, which supports the blister packs falling from the secondary silo 32 onto the second rotating plates 331, so that the blister packs are neatly stacked in groups within the secondary silo 32. When the second clearance openings 336 on the two second rotating plates 331 face each other, a channel for the blister packs to pass through is formed between the two rotating plates, and the stacked blister packs fall as a whole into the lower feed channel 333. The material channel 333 is fixedly connected to the frame 1. Its inlet is connected to the outlet of the secondary material bin 32 and its outlet is connected to the inlet of the tray 4. The cylinder 335 is installed on the frame 1. Its piston rod drives the push plate 334 to reciprocate in the material channel 333, which smoothly pushes the grouped medicine plates that fall into the material channel 333 to the tray 4 so that they can enter the subsequent boxing process.

[0042] To ensure that blister packs are grouped and ready for packaging, please refer to the instructions below. Figure 10 In a preferred embodiment, the slab arrangement mechanism 4 includes a three-stage conveyor belt 41 and partitions 42. A plurality of partitions 42 are spaced apart on the three-stage conveyor belt 41 along the length direction of the three-stage conveyor belt 41, and the spacing between adjacent partitions 42 is adapted to the width of the slab.

[0043] In use, the blister packing mechanism 4 consists of a three-stage conveyor belt 41 and multiple partitions 42. The partitions 42 are spaced apart along the length of the three-stage conveyor belt 41 and fixed on it. The spacing between adjacent partitions 42 is adapted to the width of the blister packs, forming multiple independent packing stations. After the blister packs pushed by the two-stage blister packing assembly 33 enter the three-stage conveyor belt 41, they are confined within the station between two adjacent partitions 42. The partitions 42 provide lateral positioning and limiting for the blister packs, preventing them from shifting, scattering, or flipping during transport. When the three-stage conveyor belt 41 operates, it drives the partitions 42 and the blister packs forward synchronously, ensuring that each blister pack is transported to the subsequent boxing station in a neat and stable manner, guaranteeing the consistency and reliability of the blister pack transport and improving boxing efficiency and accuracy.

[0044] To better understand this invention, the following is combined with... Figure 1 - Figure 10 The working principle of an automatic blister pack separating and conveying device according to the present invention is described in detail as follows: The blister packs first enter the primary hopper 22 via the primary conveyor belt 21. The primary blister pack separating assembly 23 separates and sends out the stacked blister packs one by one, completing the first blister pack separation and drop. Then, the blister packs enter the secondary conveyor belt 31 and are conveyed to the inclined arc-shaped secondary hopper 32, realizing the second drop. Through the two-stage segmented conveying of the primary conveying mechanism 2 and the secondary conveying mechanism 3, the original large drop height is split into two small drops, which greatly reduces the single drop height. At the same time, the inclined arc-shaped secondary hopper 32 guides and buffers the blister packs to prevent them from overturning due to inertial impact on the hopper wall, so that the blister packs are stacked stably and orderly. Then, the secondary blister pack separating assembly 33 sends them to the stacking mechanism 4 in groups, ensuring neat and stable conveying.

[0045] The specific embodiments of the present invention described above do not constitute a limitation on the scope of protection of the present invention. Any other corresponding changes and modifications made in accordance with the technical concept of the present invention should be included within the scope of protection of the claims of the present invention.
