Description

Technical Field

[0001] This invention relates to the field of warehousing and logistics technology, specifically to a pallet conveying device for warehousing and logistics. Background Technology

[0002] Pallet conveyors are core equipment in automated warehousing and logistics systems. Through mechanical transmission, power drive, and intelligent control, they enable automated handling of pallets and their cargo. Motors and reducers provide driving force to ensure stable operation. Conveyor belts, rollers, and chain plates support the pallets and adapt to different cargo shapes. Sensors and PLCs enable path planning, obstacle avoidance, and task scheduling. Metal materials support the entire structure to ensure stability and durability. Roller and chain conveyors can operate 24 hours a day to increase throughput.

[0003] Existing pallet conveyor systems for warehousing and logistics often encounter issues when receiving goods from different manufacturers. These pallets come in varying sizes, and the spacing of the conveyor belts, rollers, or chain plates is designed based on standard pallet dimensions. If a pallet is too long, too wide, or has an abnormal shape, it can cause jamming, tilting, or even detachment, leading to equipment malfunctions or damage to goods. AGVs, stacker cranes, and other equipment rely on pallet dimensions for path planning and gripping operations. Size deviations can cause robotic arm gripping failures, forks failing to insert into pallet holes, or even collisions with the racks. The height and span of automated warehouse racks are typically designed based on standard pallets. Non-standard pallets result in wasted rack height or inability to place goods in designated locations, reducing storage density. Summary of the Invention

[0016] Beneficial effects

[0017] The present invention has the following beneficial effects:

[0018] This pallet conveying device for warehousing and logistics uses a lifting mechanism at the bottom of a chain conveyor to create a certain height difference between the palletized goods and the pallet base. A pusher plate supports the goods, while clamping plates at both ends hold them in place, moving the goods onto the pallet base. The inclined surface of the pallet base facilitates the movement of the goods. A control rail-mounted heavy-duty pusher removes the two pallet bases outwards, and the clamping plates return to their original position, thus moving the goods onto the pallet used in this warehousing and logistics operation. This facilitates the transfer of goods to the pallet used in this warehousing and logistics operation, and makes it convenient to store the goods on the warehousing and logistics racks.

[0029] Please see Figures 1-6 The present invention provides a technical solution: a pallet conveying device for warehousing and logistics, including two roller conveyor devices 1, a chain conveyor device 2 connected between the two roller conveyor devices 1, a rail-mounted heavy object pusher 5 installed between the two roller conveyor devices 1, a material clamping shell 7 installed on the outer surface of the rail-mounted heavy object pusher 5, a telescopic cavity 8 opened inside the material clamping shell 7, and two material clamping components installed inside the material clamping shell 7.

[0030] The material clamping assembly includes a drive assembly and two clamping assemblies. Each clamping assembly includes a lead screw slider 15 and a lead screw slider 26. Lead screw slider 15 is mounted on the outer surface of the drive assembly, and lead screw slider 26 is also mounted on the outer surface of the drive assembly. A rotating column 17 is movably mounted inside lead screw slider 15, and a rotating column 28 is movably mounted inside lead screw slider 26. A bracket 20 is movably mounted on the outer surface of rotating column 17, and a bracket 21 is movably mounted on the outer surface of rotating column 28. A rotating column 39 is movably mounted inside either bracket 10 or bracket 21. A clamping plate 24 is mounted on the outer surface of rotating column 39. Several limiting slide rails 22 are evenly distributed inside the telescopic cavity 8. The outer surface of the clamping plate 24... Several limiting sliders 23 are evenly distributed on the surface. The outer surface of the limiting sliders 23 is in active contact with the outer surface of the limiting slide rail 22. In cooperation with the elevator 4 at the bottom of the chain conveyor 2, the height of the palletized goods from other manufacturers is at a certain difference from the height of the pallet bottom plate 32. The push plate 31 pushes and supports the goods, and the clamping plates 24 at both ends clamp them, so that the goods are moved to the pallet bottom plate 32. The inclined surface 33 of the pallet bottom plate 32 facilitates the movement of goods. The control rail heavy object pusher 6 removes the two pallet bottom plates 32 outward and controls the clamping plates 24 to return, so that the goods are moved to the pallet used in this warehousing and logistics, thus facilitating the movement of goods to the pallet used in this warehousing and logistics, and facilitating the storage of goods on the warehousing and logistics rack.

[0031] The drive assembly includes a motor 9 and a main ball screw 10. The motor 9 is mounted on the top surface of the material clamping shell 7. The main ball screw 10 is mounted on the outer surface of the output end of the motor 9. A driven ball screw 14 is movably mounted inside the material clamping shell 7. A main sprocket 11 is mounted on the outer surface of the main ball screw 10, and a driven sprocket 12 is mounted on the outer surface of the driven ball screw 14. A chain 13 is movably mounted on the outer surfaces of the main sprocket 11 and the driven sprocket 12 together. Two lead screw sliders 15 are in active contact with the outer surfaces of the main ball screw 10 and the driven ball screw 14, respectively. Two lead screw sliders 16 are in active contact with the outer surfaces of the main ball screw 10 and the driven ball screw 14, respectively. The controller controls two motors 9 to work. The motors 9 drive the main ball screw 10 to rotate. The main ball screw 10 drives the driven ball screw 14 to rotate through the main sprocket 11 and the chain 13.

[0032] A motor 25 is mounted on the top surface of the material clamping shell 7. A worm gear 26 is mounted on the outer surface of the output end of the motor 25. Two rotating columns 28 are movably mounted inside the material clamping shell 7. Worm wheels 27 are mounted on the outer surfaces of both rotating columns 28. The outer surfaces of the worm gear 26 and the worm wheels 27 mesh with each other. Gear rings 29 are mounted on the outer surfaces of both rotating columns 28. A push plate 31 is movably mounted on one end surface of the material clamping shell 7. Gear racks 30 are mounted on both ends of the push plate 31. The outer surfaces of the gear racks 30 mesh with the outer surfaces of the gear rings 29. The chain conveyor 2 has an adjustment chamber 3 inside. A lift 4 is mounted at the bottom of the chain conveyor 2. Two rail weights are mounted on the outer surface of one of the roller conveyor devices 1. The second type of pallet mover 6 has two pallet base plates 32 movably mounted on their outer surfaces. The pallet base plates 32 have inclined surfaces 33. With the cooperation of the lifting machine 4 at the bottom of the chain conveyor 2, the height of the palletized goods from other manufacturers is made to be at a certain difference from the height of the pallet base plates 32. The push plate 31 pushes and supports the goods, and the clamping plates 24 at both ends clamp them, so that the goods are moved onto the pallet base plates 32. The inclined surfaces 33 of the pallet base plates 32 facilitate the movement of the goods. The control of the second type of pallet mover 6 causes the two pallet base plates 32 to be removed outwards, and the control of the clamping plates 24 to return is also made, so that the goods are moved onto the pallets used in this warehousing and logistics, thus facilitating the movement of goods onto the pallets used in this warehousing and logistics, and facilitating the storage of goods on the warehousing and logistics racks.

[0033] The workflow of this invention is as follows: When the warehousing and logistics department receives products from other manufacturers, the pallets and goods from those manufacturers are placed onto the roller conveyor device 1 using a forklift. The roller conveyor device 1 moves the pallets. However, some pallets are of a different model than those used in this warehousing and logistics department, making shelf placement inconvenient. The pallets used in this warehousing and logistics department are moved to a fixed position via the roller conveyor device 1 and the chain conveyor device 2. Two rail-mounted load-pushing machines 6 correspondingly move the pallet base plate 32 to cover the pallets used in this warehousing and logistics department. When the pallets and goods from other manufacturers move to the front of the pallet base plate 32 via the roller conveyor device 1 and the chain conveyor device 2, the rail-mounted load-pushing machine 5 moves the material clamp shell 7, thereby moving the material clamp shell 7 next to the pallets and goods from other manufacturers. The controller controls two motors 9 to work, and the motors 9 drive the main ball screw 10 to rotate. The main ball screw 10 drives the slave ball screw 1 through the main sprocket 11 and the chain 13. 4. During rotational motion, both the main ball screw 10 and the driven ball screw 14 drive the first and second ball screw sliders 15 and 16 to move. Each ball screw 10 and 14 has a left-hand thread in one section and a right-hand thread in the other, causing the first and second ball screw sliders 15 and 16 to move towards each other. This causes the first ball screw slider 15 to drive the first rotating column 17 and the first support 20 to move, while the second ball screw slider 16 drives the second rotating column 18 and the second support 21 to move. Both bracket 20 and bracket 21 are deflected at an angle on rotating column 3 19, so that clamping plate 24 drives limiting slider 23 to move stably on limiting slide rail 22, so that the two clamping plates 24 stably clamp the goods on both sides. The two clamping plates 24 move synchronously towards each other, forming symmetrical clamping force, avoiding pallet tilting or slipping due to uneven force on one side, and can adapt to uneven pallet surface or the center of gravity of goods shift. The clamping plates 24 can still maintain stable contact, ensuring a smooth pallet replacement process.

[0034] The controller controls motor 25 to operate, which drives worm 26 to rotate. The outer surfaces of worm gear 27 mesh with each other, thereby driving rotating column 28 to rotate, which in turn drives gear ring 29 to rotate. The outer surface of gear ring 29 meshes with the outer surface of gear rack 30, causing gear rack 30 to drive push plate 31 to move downwards. This continues to control the rail-mounted object pusher 5 to move material clamp shell 7, and is coordinated with the elevator 4 at the bottom of chain conveyor 2 to make it... The height of the goods on the pallet from the manufacturer is at a certain difference from the height of the pallet bottom plate 32. The push plate 31 pushes and supports the goods, and the clamping plates 24 at both ends clamp them, thereby moving the goods onto the pallet bottom plate 32. The inclined surface 33 of the pallet bottom plate 32 facilitates the movement of the goods. The control rail heavy object pusher 6 removes the two pallet bottom plates 32 outwards and controls the clamping plates 24 to return, thereby moving the goods onto the pallet used in this warehousing and logistics, thus facilitating the movement of goods onto the pallet used in this warehousing and logistics, and thus facilitating the storage of goods on the warehousing and logistics rack.
