[0026] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention will be described in further detail below with reference to the accompanying drawings.

[0027] Example 1

[0028] See also Figure 1-6 Example 1 provides a multi-station stacking and conveying device, comprising a collecting conveyor belt 4, N tablet counting and stacking machines, and N transfer conveyor structures. The tablet counting and stacking machine comprises a feed structure 1 arranged in a left-right direction, a discharge conveyor belt 2 arranged in a front-to-back direction, and a press structure 10 capable of vertical movement. Its structure is described in application number CN202211703557.2. Specifically, the front portion of the discharge conveyor belt 2 is located adjacent to the right side of the feed structure 1, and M first receiving bins 3 are arranged side by side on it. The feed structure 1 can simultaneously output laminated materials to K first receiving bins 3. Specifically, the discharge conveying structure 1 comprises multiple conveying channels arranged side by side in a front-to-back direction (for outputting single disinfectant tablets backward), a stacking bin located adjacent to the right side of the conveying channels and lower than the conveying channels, a first push rod for pushing materials from the stacking bin to the first receiving bin 3, and a lifting baffle at the right end of the stacking bin that can move up and down. The first push rod is positioned horizontally and can move in both directions. It is located below the rear end of the conveying channel. The stacking bin is positioned horizontally and is open on both sides to accommodate the material. When a certain number of disinfectant tablets are stacked in the bin, the lifting plate rises, causing the first push rod to move to the right. Multiple first push rods and multiple lifting plates are driven synchronously.

[0029] Among them, N piece counting and stacking machines are arranged side by side on the left side of the collecting conveyor belt 4. Each piece counting and stacking machine is equipped with a corresponding transfer conveying structure, which is located at the rear end of the discharge conveyor belt 2. The collecting conveyor belt 4 is arranged in the front-to-back direction, and multiple second material receiving bins 5 are arranged side by side on it. It is higher than the discharge conveyor belt 2. The guardrail on its left side is provided with a gap at the transfer conveying structure to facilitate the passage of materials. The rear end is a packaging device. The rear ends of the guardrails on both sides of the discharge conveyor belt 2 are provided with gaps to facilitate the passage of the second push rod 8 and the materials. The materials output by the N piece counting and stacking machines cannot occupy the same second material receiving bin 5 (controlled by the photoelectric sensor on the second material receiving bin 5 or a fixed beat control, etc.).

[0030] The transfer and conveying structure includes a horizontally arranged lifting silo 6, a servo-lift mechanism for driving the vertical movement of the lifting silo 6, two vertically arranged sub-silos 7 within the lifting silo 6, a second push rod 8 on the left side of the rear end of the discharge conveyor 2 for pushing material from the first receiving silo 3 to the sub-silo 7, and a third push rod 9 above the rear end of the discharge conveyor 2 for pushing material from the lifting silo 6 to the second receiving silo 5. The lifting silo 6 is located between the rear end of the discharge conveyor 2 and the merging conveyor 4. It is a rectangular structure with open left and right sides, adjacent to the discharge conveyor 2 and the merging conveyor 4, respectively. It aligns with and aligns with the rear first receiving silo 3. A second receiving silo 5 aligns with and aligns with the lifting silo 6 when in its elevated position. Both the second push rod 8 and the third push rod 9 are capable of horizontal movement. The sub-silos 7 engage with the material. The second push rod 8 can only extend into one sub-silo 7, while the third push rod 9 can simultaneously pass through all sub-silos 7. Specifically, the second push rod 8 comprises the first transverse cylinder and a first push plate at the right end of its telescopic rod, while the third push rod 9 comprises the second transverse cylinder and a second push plate at the right end of its telescopic rod. Both the first and second transverse cylinders are arranged horizontally, and both the first and second push plates are arranged vertically. When the first transverse cylinder is retracted, the first push plate is located to the left of the discharge conveyor 2. When the first transverse cylinder is extended, the first push plate passes through the first material receiving bin 3 to the left end of the lifting bin 6. When the second transverse cylinder is retracted, the second push plate is located to the left of the lifting bin 6. When the second transverse cylinder is extended, the second push plate passes through the lifting bin 6 to the left end of the second material receiving bin 5. The lower end of the first push plate is located just above the discharge conveyor 2, and its upper end is located just below the top of the sub-bin 7 at the corresponding level (where the sub-bin 7 is flush with the discharge conveyor 2). The lower end of the second push plate is located just above the collecting conveyor 4, and its upper end is located above the top material. Specifically, the lifting silo 6 includes two side panels 61 arranged side by side in front and back, a connecting and fixing plate 62 at the bottom of the two side panels 61, and three short partitions 63 arranged side by side up and down on the inner side of the side panels 61. The two side panels 61 are respectively located in the adjacent front and adjacent rear of the material. The front side panel 61 is fixed on the slide seat, and the short partitions 63 of the two side panels 61 are arranged in a one-to-one correspondence and are flush. Specifically, the short partition 63 at the top is located at the top of the side panel 61, and the short partition 63 at the bottom is located at the bottom of the side panel 61. The connecting and fixing plate 62 is arranged in the front-to-back direction. The three short partitions 63 are arranged at equal intervals, and they are all arranged horizontally in the left-right direction. The space between two adjacent short partitions 63 constitutes the sub-silo 7, and the two adjacent short partitions 63 constitute the top and bottom of the sub-silo 7, respectively. There is a gap (the width of which is greater than the width of the second push plate) between the two short partitions 63 of the same height for the second push plate to pass through, so that the second push plate can pass through all the sub-bins 7 at the same time.

[0031] The pressing structure 10 is located directly above the discharge conveyor belt 2 and between the stacking machine and the transfer conveyor structure. It is used to compact the material to facilitate its entry into the sub-bin 7. The pressing structure 10 includes a first bracket, a vertical cylinder mounted vertically on the first bracket, and a pressing plate at the lower end of the telescopic rod of the vertical cylinder. The first bracket is mounted on the frame of the discharge conveyor belt 2. The pressing plate is arranged in a left-right direction and is located directly above a first receiving bin 3. Specifically, it is a rectangular plate. When the vertical cylinder is extended, the pressing plate presses against the upper side of the material; when the vertical cylinder is retracted, the pressing plate is located above the discharge conveyor belt 2.

[0032] The servo lifting mechanism allows each sub-bin 7 (the bottom) to be flush with the discharge conveyor belt 2. When the lifting bin 6 is at a high position, the sub-bin 7 (the bottom) at the bottom is flush with the summary conveyor belt 4.

The lifting bin 6 is raised to a high position, and the third push rod 9 pushes the stack of tablets into the consolidating conveyor belt 4. If the second receiving bin 5 needs to output 100 tablets, the process is as follows: the top sub-bin 7 is aligned with the discharge conveyor belt 2, and the second push rod 8 pushes the tablets into the top sub-bin 7. The lifting bin 6 rises, and then the bottom sub-bin 7 is aligned with the discharge conveyor belt 2. The second push rod 8 pushes the tablets into the bottom sub-bin 7, resulting in two stacks of tablets in the lifting bin 6. The lifting bin 6 is raised to a high position, and the third push rod 9 pushes the two stacks of tablets into the consolidating conveyor belt 4, with the upper stack of tablets falling onto the lower stack of tablets, forming a single stack.

[0034] The servo lift mechanism in this embodiment of the utility model includes a second bracket, a vertically mounted slide rail behind the second bracket, a slide slidably mounted on the slide rail, and a screw lift assembly or synchronous belt lift assembly between the slide and the second bracket.

The second transverse cylinder is fixed to the left side of the second bracket, and the first transverse cylinder is fixed to the frame of the discharge conveyor belt 2.

[0035] Preferably, the first push plate and the second push plate in the embodiment of the present invention are rectangular plates, with their lower ends bent rightward to form a horizontal push-up slope. The first push plate and the second push plate should ensure that they can push materials (e.g., multiple disinfectant tablets) toward the corresponding structure. The push-up slope is less than 5 mm long, with its upper side extending diagonally downward from left to right, and its right end (the tip) less than 2 mm thick.

[0036] Among them, the discharge conveyor belt 2 and the summary conveyor belt 4 in the embodiments of the present utility model are both step-by-step conveying structures. M, N, and K are all integers greater than or equal to 2, M is greater than 2K, K is 2 - 10, and N is 2 - 4. The first receiving bin 3 at the rear end of the discharge conveyor belt 2 can be aligned with a certain second receiving bin 5 in the left-right direction. Both the first receiving bin 3 and the second receiving bin 5 are U-shaped structures adapted to the material. The U-shaped structure is arranged in the left-right direction, and the left end of its vertical arm is bent away from the material from right to left to form a feeding inclined plane (the two feeding inclined planes form an eight-shaped for the convenience of the material to enter).
