Description

Technical Field

[0001] This invention relates to a conveying device, and more particularly to a conveying device for a pharmaceutical liner boxing machine. Background Technology

[0002] Automated cartoning of pharmaceutical plates is a crucial step in the downstream packaging process of the pharmaceutical and health product industries. Cartoning machines typically include stations for plate conveying, instruction leaflet folding and insertion, carton opening, plate and instruction leaflet placement, and carton lid closing. The stability, efficiency, and accuracy of plate delivery to the cartoning station directly impacts the machine's operating speed, reliability, and packaging quality. In existing technologies, pharmaceutical plate cartoning machines often use chain or belt conveyor lines. A common structure involves a series of fixed or adjustable baffles or partitions along a conveyor line, forming a continuous hopper to support and convey the plates. When the hopper reaches the cartoning station, the plate is pushed into or sucked into the waiting carton. The hopper opening is fixed, typically only slightly wider than the plate thickness. Therefore, when feeding the hopper, the plate cannot fall into it smoothly and efficiently, leading to jamming, scratching, or even damage during subsequent cartoning, especially when handling plates of varying sizes or slightly deformed plates. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a conveying device for a pharmaceutical cartoning machine that significantly improves the stability and reliability of feeding and cartoning.

[0004] The technical solution adopted by the present invention to solve its technical problem is: a conveying device for a pharmaceutical plate cartoning machine, including a frame, a feeding mechanism and a conveying mechanism on the frame, the conveying mechanism being located below the feeding mechanism, the conveying mechanism including a conveying seat, a conveying groove on the conveying seat, a chain conveyor belt composed of multiple chain links in the conveying groove, a conveying base plate on the upper side of the chain conveyor belt, the bottom of the conveying base plate being connected to two adjacent chain links, a hopper side plate on the conveying base plate, and a hopper for placing pharmaceutical plates being formed between two adjacent hopper side plates, the conveying groove including a horizontal section and an upwardly curved opening section, the top of the opening section being located directly below the feeding mechanism, when the hopper is conveyed to the opening section, the hopper side plates on both sides are tilted to both sides under the action of the conveying groove to increase the size of the hopper opening.

[0005] Using the above structure, the chain conveyor belt spliced ​​with chain links, together with the conveyor base plate, forms a stable circulating conveying system. This ensures that the hopper remains closed in the horizontal section to accurately position the medicine plates, while it can quickly expand in the open section to receive materials. No additional cylinders or motors are required, simplifying the control system, enabling high-speed continuous operation, improving the smoothness of medicine plate feeding, and avoiding the jamming and scratching problems caused by traditional fixed openings.

[0006] Preferably, the hopper has at least one additional set of conveyor base plates between the two conveyor base plates on which the hopper side plates are located, and a pad is provided on the upper side of the conveyor base plates. This structure enhances the structural stability of the hopper and allows for adjustment of the medicine plate height via the pad, ensuring the medicine plate remains flat during transport.

[0007] Preferably, there are two conveyor seats, which are arranged parallel to each other on the frame. There are also two conveying troughs, each located on the inner and outer side walls of one of the conveyor seats. Each conveying trough in both conveyor seats is equipped with a chain conveyor belt. This structure, employing parallel double conveyor seats and a double chain conveyor belt design, significantly improves the conveying capacity and stability by synchronously driving the hopper side plates from both sides. The symmetrical structure distributes stress, reduces unilateral wear, and extends equipment life. Simultaneously, it provides precise linkage control for the outward expansion of the side plates in the hopper opening section.

[0008] Preferably, the side plates of the hopper on both sides are connected to the conveyor base plates on the two conveyor seats.

[0009] Preferably, the chain conveyor belt includes chain links assembled from inner chain plates, pins, and sleeves. Two adjacent chain links are connected by outer chain plates and pins, and one of the pins on the chain link passes through the outer chain plate and is connected to the conveyor base plate.

[0010] Preferably, the bottom of the conveyor base plate is provided with a connecting plate, which is fastened to the pins of two adjacent outer chain plates.

[0011] Preferably, the connecting plate includes a first connecting plate and a second connecting plate. The first and second connecting plates are respectively provided with a horizontal opening slot and a vertical opening slot, which are fastened to a pin. The first connecting plate covers the second connecting plate of another adjacent conveyor base plate and is connected by the same pin. This structure allows for quick disassembly and maintenance of the conveyor base plate while ensuring synchronization between the conveyor base plate and the chain, preventing misalignment that could cause the medicine plate to shift.

[0012] Preferably, the tops of the side panels on both sides of the hopper are curved outwards and equipped with guide plates. This structure guides the medicine tablets precisely into the hopper during feeding, reducing the risk of edge collisions. This design further reduces the probability of tablet deformation or jamming, making it particularly suitable for high-speed continuous operation scenarios.

[0013] Preferably, the frame is provided with at least two sets of feeding mechanisms, and the conveyor seat is provided with an opening section below each of the two sets of feeding mechanisms. With the above structure, two or more sets of feeding mechanisms cooperate with the corresponding opening sections to realize parallel feeding at multiple stations, significantly improving conveying efficiency. The optimized distribution of the opening sections allows the hopper to dynamically expand at multiple positions, adapting to the needs of high-cycle production and shortening the overall boxing cycle.

[0014] This invention solves the problems of poor compatibility and material jamming in traditional fixed silos through innovations such as dynamic flaring, modular structure, and dual-track synchronous drive. It achieves high-speed, stable, and low-loss conveying while ensuring the integrity of the medicine plates. Attached Figure Description

[0023] The technical solution of the present invention will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings. Example

[0024] like Figures 1 to 7The diagram shows a conveying device for a pharmaceutical plate cartoning machine, comprising a frame 1, a feeding mechanism 2 and a conveying mechanism mounted on the frame 1, the conveying mechanism being positioned below the feeding mechanism 2, and a conveying base 3. The conveying base 3 has a conveying groove 31, and a chain conveyor belt 4 composed of multiple chain links is disposed within the conveying groove 31. A conveying base plate 5 is mounted on the upper side of the chain conveyor belt 4, and the bottom of the conveying base plate 5 is connected to two adjacent chain links. A hopper side plate 6 is mounted on the conveying base plate 5, and a hopper 7 for placing pharmaceutical plates is formed between two adjacent hopper side plates 6. The conveying groove 31 includes a horizontal section 32 and an upwardly curved opening section 33, the opening section 33 comprising two inclined sections, one upwardly inclined and one downwardly inclined. Located at the top between the two inclined sections, the top of the opening section 33 is directly below the feeding mechanism 2. When the hopper 7 is conveyed to the opening section 33, specifically, the hopper 7 is directly below the feeding mechanism 2, and the conveying base plate 5 containing the hopper side plates 6 on both sides is located within the inclined sections on both sides of the top of the opening section 33. Under the limiting action of the inclined sections on both sides of the opening section 33, the conveying base plate 5 is in an inclined state, and the hopper side plates 6 on it are inclined to both sides to increase the size of the opening of the hopper 7. When the hopper 7 enters or leaves the opening section 33, the hopper side plate 6 located in the opening section 33 is inclined, while the other hopper side plate 6 is still in a vertical state. Because there is a gap between the medicine plate and the hopper 7 and the inclination arc of the hopper side plate 6 is small, the inclined hopper side plate 6... It will not squeeze or scratch the medicine plate, causing it to deform or break. When the conveyor base plate 5 corresponding to the side plates 6 on both sides of the hopper 7 moves out of the opening section 33 and enters the subsequent horizontal section, the corresponding side plates 6 return from the inclined state to the vertical state. The chain conveyor belt 4 spliced ​​with chain links, together with the conveyor base plate 5, forms a stable circulating conveying system, ensuring that the hopper 7 remains closed in the horizontal section 32 to accurately position the medicine plate, and quickly expands in the opening section 33 to receive the material. No additional cylinder or motor drive is required, simplifying the control system, realizing high-speed continuous operation, improving the smoothness of medicine plate feeding, and avoiding the jamming and scratching problems caused by traditional fixed openings. The hopper 7 has at least one set of conveyor base plates 5 between the two conveyor base plates 5 where the side plates 6 are set. The hopper 7 has a pad plate 8 on the upper side of the conveyor base plate 5 to enhance the structural stability of the hopper 7. The height of the medicine plate can also be adjusted by the pad plate 8 to ensure that the medicine plate remains flat during the conveying process.

[0025] There are two conveyor seats 3, which are arranged in parallel on the frame 1. There are also two conveyor troughs 31, which are respectively located on the inner and outer side walls of the conveyor seats 3. Each of the two conveyor troughs 31 of the two conveyor seats 3 is equipped with a chain conveyor belt 4. The design of parallel double conveyor seats 3 and double chain conveyor belts 4 is adopted. By synchronously driving the side plates 6 of the hopper on both sides, the conveying load-bearing capacity and stability are greatly improved. The symmetrical structure distributes the force, reduces wear on one side, and extends the service life of the equipment. At the same time, it provides precise linkage control for the outward expansion of the side plates of the opening section 33. The side plates 6 of the hopper 7 on both sides are connected to the conveyor base plates 5 on the two conveyor seats 3. Specifically, the conveyor base plates 5 are set on the chain conveyor belts 4 in the conveyor troughs 31 on both sides of the same conveyor seat 3. The conveyor base plates 5 on the two conveyor seats 3 are synchronously set. The side plates 6 of the hopper 7 on both sides are connected to the conveyor base plates 5 on the two conveyor seats 3 and extend to the upper side of the conveyor base plate 5 on the other conveyor seat 3 that is synchronous with it.

[0026] The chain conveyor belt 4 includes chain links assembled from inner chain plates 41, pins 42, and sleeves 43. Adjacent chain links are connected by outer chain plates 44 and pins 42. One pin 42 on each chain link passes through the outer chain plate 44 and connects to the conveyor base plate 5. The bottom of the conveyor base plate 5 is provided with a connecting plate, which is fastened to two adjacent pins 42 that pass through the outer chain plates 44. The connecting plate includes a first connecting plate 51 and a second connecting plate 52. The first connecting plate 51 and the second connecting plate 52 are respectively provided with a horizontal opening groove 53 and a vertical opening groove 54. The horizontal opening groove 53... The vertical opening slot 54 is fastened to the pin 42. The first connecting plate 51 covers the second connecting plate 52 of the adjacent conveying base plate 5 and is connected by the same pin 42. This enables quick disassembly and maintenance of the conveying base plate 5 and ensures the synchronization of the conveying base plate 5 and the chain, avoiding misalignment that could cause the medicine plate to shift. During installation, the horizontal opening slot 53 is first fastened to the pin 42, and the connecting plate is rotated around the pin 42 to fasten the vertical opening slot 54 to another pin 42. To facilitate the fastening of the vertical opening slot 54 to the pin 42, the opening end of the vertical opening slot 54 adopts a wedge-shaped opening structure.

[0027] The tops of the side plates 6 on both sides of the hopper 7 are bent outwards and have guide plates 61, which guide the medicine plate to fall accurately into the hopper 7 during material feeding, reducing the risk of edge collision. This design further reduces the probability of medicine plate deformation or jamming, and is especially suitable for high-speed continuous operation scenarios.

[0028] At least two sets of feeding mechanisms 2 are provided on the frame 1. The conveyor seat 3 is provided with an opening section 33 below each of the two sets of feeding mechanisms 2. The two or more sets of feeding mechanisms 2 cooperate with the corresponding opening sections 33 to realize parallel feeding at multiple workstations, which significantly improves the conveying efficiency. The optimized distribution of the opening sections 33 enables the material bins 7 to be dynamically expanded at multiple positions. The feeding mechanisms 2 feed the material bins 7 in an alternating manner to adapt to the needs of high-speed production and shorten the overall boxing cycle.
