Detailed Embodiments

[0015] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0016] The following will describe this in conjunction with the preferred embodiments of the device of the present invention.

[0017] Please refer to Figure 1-7 As shown, the automatic stacking and separating device for logistics pallets includes a conveying rail 1, the conveying rail 1 is horizontally placed, and a support frame 2 is erected in the middle of the conveying rail 1. A lifting and adjusting mechanism 3 is installed inside the support frame 2. A clamping mechanism 4 is provided on one side of the lifting and adjusting mechanism 3. At the bottom of the conveying rail 1 and beside the clamping mechanism 4, a separating mechanism 5 is provided. Logistics pallets 6 are placed at equal intervals on the conveying rail 1.

[0018] In another embodiment provided by the present invention, as Figure 5 shown, the lifting and adjusting mechanism 3 includes a first motor 301, a connecting shaft 302, a synchronous pulley 303, a synchronous belt 304, a connecting member 305, and an auxiliary component 306. The first motor 301 is fixedly installed inside the top of the support frame 2. The connecting shafts 302 are correspondingly arranged at the upper and lower parts inside the support frame 2. The output end of the first motor 301 is transmitted to the upper connecting shaft 302 through a commutator. Synchronous pulleys 303 are sleeved at the ends of the upper and lower connecting shafts 302. Synchronous belts 304 are wound between the upper and lower synchronous pulleys 303 on both sides. A connecting member 305 is provided on the belt body of the synchronous belt 304. Two groups of auxiliary components 306 are provided and are correspondingly arranged inside the support frame 2.

[0019] Furthermore, the auxiliary component 306 includes a first ear seat 3061, a guide shaft 3062, and a first connecting block 3063. The first ear seats 3061 are arranged correspondingly up and down, and a guide shaft 3062 is installed between the upper and lower first ear seats 3061. Two groups of first connecting blocks 3063 are provided outside the guide shaft 3062. Through the power provided by the connecting member 305, the clamping mechanism 4 is lifted and lowered on the guide shaft 3062 of the auxiliary component 306.

[0020] Specifically, start the first motor 301. The motor output shaft starts to rotate, and the rotational power is transmitted to the upper connecting shaft 302 through the commutator, causing it to start rotating. The rotation of the upper connecting shaft 302 drives the synchronous pulley 303 at its end to rotate. Then, the rotational power is transmitted to the lower synchronous pulley 303 through the synchronous belt 304. The upper and lower synchronous pulleys 303 rotate synchronously, driving the synchronous belt 304 to move in the closed-loop drive system. The connecting member 305 on the synchronous belt 304 moves together with the synchronous belt 304. Since the connecting member 305 is fixedly connected to the side of the mounting plate 401, the mounting plate 401 and the clamping mechanism 4 also move up and down. Under the action of the auxiliary component 306, the movement of the mounting plate 401 and the clamping mechanism 4 is more stable, avoiding shaking or deviation. When the first motor 301 rotates to the specified position, the motor operation is stopped through the control system. At this time, the mounting plate 401 and the clamping mechanism 4 also stop at the required height position. If it is necessary to adjust the height of the mounting plate 401 and the clamping mechanism 4 to another position, just start the first motor 301 in reverse. The motor output shaft rotates in the reverse direction, and the rotational power is transmitted to the upper connecting shaft 302 through the commutator, and then drives the synchronous pulley 303 and the synchronous belt 304 to move in the reverse direction. The connecting member 305 moves in the reverse direction together with the synchronous belt 304, driving the mounting plate 401 and the clamping mechanism 4 to move up and down to a new height position.

[0021] In another embodiment provided by the present invention, as Figure 6 shown, the clamping mechanism 4 includes a mounting plate 401. The side plate of the mounting plate 401 is fixedly connected to the first connecting block 3063. The end face of the mounting plate 401 away from the first connecting block 3063 is provided with second ear seats 402. There are two groups of second ear seats 402 arranged up and down, and the two groups of second ear seats 402 are linearly distributed along the end face of the mounting plate 401. A sliding shaft 403 is installed in the two groups of second ear seats 402. Opposite to the outside of the sliding shaft 403 are second connecting blocks 404. The outside of the two second connecting blocks 404 is connected with a connecting plate 405. The outside of the connecting plate 405 is provided with a clamping plate 406. The back side plate of the mounting plate 401 is fixedly installed with a second motor 407. The output end of the second motor 407 is connected with a rotating shaft through a commutator, and the rotating shaft penetrates to the other end face of the mounting plate 401 and is connected with a rotating plate 408. Both ends of the rotating plate 408 are connected with fish-eye rods 409. The other ends of the two fish-eye rods 409 are fixedly connected with the connecting plate 405.

[0022] Further, the rotating plate 408 is rhomboid-shaped. The rotating plate 408 is rhomboid-shaped and is connected to the connecting plate 405 through fish-eye rods 409 at both ends, forming a swinging mechanism.

[0023] Further, the connecting member 305 is fixedly connected to the side of the mounting plate 401.

[0024] Specifically, start the second motor 407. The output shaft of the motor starts to rotate. Through the commutator, the rotational power is transmitted to the rotating plate 408, causing it to start rotating around the central axis. The rotation of the rotating plate 408 drives the fisheye rod 409 to perform a swinging motion. The other end of the fisheye rod 409 then pushes the connecting plate 405 to move towards each other along the sliding shaft 403. Since the connecting plate 405 is fixedly connected to the clamping plate 406, the clamping plate 406 also moves towards each other with the connecting plate 405 and gradually approaches the logistics tray 6. When the clamping plate 406 contacts the logistics tray 6 and applies sufficient clamping force, the logistics tray 6 is firmly clamped. When it is necessary to release the logistics tray 6, reverse-start the second motor 407. The output shaft of the motor rotates in the reverse direction. Through the commutator, the rotational power is transmitted to the rotating plate 408 again, causing it to start rotating in the reverse direction around the central axis. The rotation of the rotating plate 408 drives the fisheye rod 409 to perform a reverse swinging motion. The other end of the fisheye rod 409 then pushes the connecting plate 405 to move away from each other along the sliding shaft 403. Since the connecting plate 405 is fixedly connected to the clamping plate 406, the clamping plate 406 also moves away from each other with the connecting plate 405 and gradually moves away from the logistics tray 6. When the clamping plate 406 completely releases the logistics tray 6, the logistics tray 6 is in a free state and can be conveyed away by the conveying rail 1.

[0025] In another embodiment provided by the present invention, as Figure 7 shown, the separating mechanism 5 includes a fixing plate 501, a lifting cylinder 502, a fixing sleeve 503, a connecting rod 504, a lifting plate 505, a bearing plate 506, and a through hole 507. The fixing plate 501 is arranged between the crossbeams of the conveying rail 1. The bottom of the fixing plate 501 is fixedly installed with a lifting cylinder 502. A plurality of fixing sleeves 503 are penetrated through the fixing plate 501. The connecting rod 504 is slidably arranged on the plurality of fixing sleeves 503. The output end of the lifting cylinder 502 and one end of the connecting rod 504 are both connected to a lifting plate 505. The other end of the connecting rod 504 is connected to a bearing plate 506, and a through hole 507 for the lifting cylinder 502 to pass through is formed on the bearing plate 506.

[0026] Specifically, when it is necessary to stack the logistics pallets 6, the lifting cylinder 502 is activated. The piston rod of the cylinder extends, and the lifting plate 505 rises with the piston rod. The connecting rod 504 and the bearing plate 506 rise accordingly. The bearing plate 506 lifts the first conveyed logistics pallet 6 and clamps the pallet through the cooperation of the clamping mechanism 4. Then, the lifting and adjusting mechanism 3 is activated to drive the clamping mechanism 4 and the logistics pallet 6 to rise to the stacking position. When the next logistics pallet 6 is conveyed, the clamping mechanism 4 releases the logistics pallet 6 to complete the stacking. When it is necessary to separate the logistics pallets 6, first, the lifting cylinder 502 is activated. Then, the upper logistics pallet 6 is clamped through the cooperation of the clamping mechanism 4. Then, the logistics pallet 6 clamped on the clamping mechanism 4 is moved upward through the cooperation of the lifting and adjusting mechanism 3. When it rises and is far away from the bottommost logistics pallet 6, the piston rod of the lifting cylinder 502 contracts to drive the logistics pallet 6 to descend onto the conveying rail 1 and be conveyed away by the conveying rail 1. By repeating the above operations, the separation between each pallet is achieved.

[0027] During use, the logistics pallets 6 to be processed are placed at equal intervals on the conveying rail 1. Then, through the external driving mechanism, the conveying rail 1 conveys the logistics pallets 6 to the side of the clamping mechanism 4. Then, the lifting cylinder 502 in the separation mechanism 5 is activated. The piston rod of the cylinder extends, and the lifting plate 505 rises with the piston rod, driving the connecting rod 504 and the bearing plate 506 to rise. The bearing plate 506 lifts the first conveyed logistics pallet 6 to an appropriate height. The second motor 407 in the clamping mechanism 4 is activated, and the fish-eye rod 409 is driven to swing through the commutator and the rotating plate 408. The fish-eye rod 409 pushes the connecting plate 405 and the clamping plate 406 to move towards each other along the sliding shaft 403 to clamp the lifted logistics pallet 6. The first motor 301 in the lifting and adjusting mechanism 3 is activated to drive the connecting member 305 to move. The connecting member 305 drives the mounting plate 401 and the clamping mechanism 4 to rise to the stacking position. When the next logistics pallet 6 is conveyed, the clamping mechanism 4 reversely activates the second motor 407 to release the clamped logistics pallet 6 to complete the stacking. Repeat the operations of activating the lifting cylinder 502 and clamping the logistics pallet 6 in the stacking step, but this time it is to clamp the upper logistics pallet 6 in the stack. Activate the lifting and adjusting mechanism 3 to raise the clamping mechanism 4 and the upper logistics pallet 6 to a certain height to ensure separation from the lower pallet. The piston rod of the lifting cylinder 502 contracts to drive the logistics pallet 6 to descend onto the conveying rail 1 and be conveyed away by the conveying rail 1. By repeating the above operations, each pallet is separated until all pallets are separated. This not only significantly improves production efficiency, reduces the time required for stacking and separation, but also reduces the dependence on a large amount of labor, thereby reducing labor costs. This transformation enables enterprises to better cope with the expansion of production scale and the acceleration of production rhythm, and improves the overall production efficiency.

Those skilled in the art should understand that the present invention is not limited by the above embodiments.
