[0002] Pallet conveying is a method of logistics transportation and cargo handling that involves the use of pallets of standardized sizes to load, move and store goods. In the conveying system, the pallet body can be transported by conveyor rollers, and the goods can be placed on the pallet. It is often used on production lines.
[0003] When conveying pallets on the production line, if deviation occurs, it will lead to inaccurate processing positioning. Therefore, it is necessary to ensure strict center position conveying. Common correction structures are usually based on guidance, which makes it difficult to ensure absolute center position conveying. Therefore, it is necessary to design a correction device that can ensure that the pallet is stable in the center of the conveyor roller. Utility Model Content

[0018] The driving assembly includes a driving slot 32 and a servo motor 35. The driving slot 32 is opened in the baffle 3 and is aligned with the baffle 3. The servo motor 35 is fixed on the side wall of the baffle 3 and is aligned with the driving slot 32. A bidirectional screw rod 34 is rotatably connected in the driving slot 32. The end of the bidirectional screw rod 34 is fixed on the output end of the servo motor 35. A pair of sliding blocks 33 are slidably connected in the driving slot 32. The bidirectional screw rod 34 passes through the sliding block 33 and is threadedly connected to the sliding block 33. The sliding block 33 is fixed to the end of the correction plate 31.
[0019] Working principle: First, connect the entire device to an external power source, and use the rotation of the conveying roller 11 to drive the pallet body 2 to move in the conveying frame 1. During this process, the limiting plate 21 at the bottom of the pallet body 2 moves in the limiting groove 12 on the conveying roller 11 to perform a rough limiting operation to achieve relatively stable movement of the pallet body 2. Secondly, when the pallet body 2 moves to align with the laser rangefinder 4, the laser rangefinders 4 on both sides measure the distance between the pallet body 2 and the laser rangefinder 4. If the distance with the side wall of the pallet body 2 is consistent, it means that the pallet body 2 is at the center of the conveying roller 11 and no correction is required. The baffle 3 can be driven to rise by blocking the baffle 3, so that the front end of the pallet body 2 can be aligned with the baffle 3, thereby realizing the return of the pallet body 2, and then the synchronous movement of the correction plate 31 can be used to clamp the two sides of the front end of the pallet body 2. Due to the synchronous movement of the correction plate 31, the pallet body 2 can be moved to the center position of the conveying roller 11. During the whole process, the extension and retraction of the output end of the cylinder 36 can be used to realize the lifting and lowering drive of the baffle 3, and the drive of the servo motor 35 can be used to drive the bidirectional screw rod 34 to rotate, thereby driving the sliding block 33 to slide in the opposite direction synchronously, and finally driving the correction plate 31 to slide in the opposite direction synchronously.
