Description
Technical Field
[0001] The utility model relates to the technical field of folding pallet machines, and particularly relates to a pallet centering device for a folding pallet machine. Background Art
[0002] A folding pallet machine, also called a pallet folding machine, is a highly automated pallet splitting and stacking machine, which perfectly realizes the effective unity of a pallet splitting machine and a pallet stacking machine, and can efficiently realize the automatic stacking of empty pallets and the automatic splitting process of stacked pallets. The folding pallet machine is widely used in automated stereoscopic warehouses and modern production lines. Its working process is simple and fast, greatly reducing the floor area occupied by empty pallets, reducing the labor intensity of workers, and improving the production efficiency of factory warehousing.
[0003] At present, although the folding pallet machines in the prior art can meet the use requirements of pallet stacking and splitting, during the stacking and splitting processes, as the folding pallet machine works, multiple pallets stacked to a certain height on it are prone to position deviation, inclination, and even falling off, resulting in deformation or even damage of the pallets, which has a certain impact on the pallet stacking and splitting processes. At the same time, to reduce the occurrence of the above phenomena, most folding pallet machines are usually provided with a frame and a baffle structure adapted to the size of the pallet on the main body to center the pallet to ensure the stability of the pallet during folding. To ensure the stable movement of the pallet during folding, such a baffle structure usually leaves a certain gap with the pallet edge, resulting in the phenomenon that the pallet is prone to dislocation during folding. In addition, the structure of the baffle on most folding pallet machines is usually relatively simple and has a single function, which is likely to cause a certain degree of wear on the pallet surface and increase unnecessary working noise.

Component 3 includes a first roller group 31 and a second roller group 32 which are distributed in a horizontal and vertical staggered manner and are staggered and evenly arranged with respect to the fork teeth 11. The first roller group 31 and the second roller group 32 are respectively rotatably arranged on a mounting frame 4 which is slidably arranged inside the first side plate 1 and a mounting seat 5 which is correspondingly arranged at both ends of the first side plate 1, and are placed at a plurality of notches 12 which are opened at corresponding positions on the plate surface of the first side plate 1. The mounting frame 4 and the mounting seat 5 are respectively connected to a plurality of groups of first cylinders 6 and second cylinders 7 which are arranged at corresponding positions on the first side plate 1 and drive them to slide.
[0020] Specifically in this embodiment, Figure 1 Taking a pallet unstacking machine body 100 with a conventional structure as an example, the lifting component 101 is set with a common scissor-type lifting structure. The pallet can be placed on the lifting component 101 and move upward along the upper frame structure 102 under the action of the lifting component 101. In the process of the lifting component 101 driving the pallet to rise, the side of the pallet can move the forks 11 at the corresponding positions of the first side plate 1 and the second side plate 2 on both sides of the frame to rotate at an appropriate angle, and when the pallet moves above the fork teeth 11, the fork teeth 11 rotate and return to the initial position, and the lifting component 101 drives the pallet to descend while the pallet is placed above the fork teeth 11 for clamping, thereby realizing the stacking and unstacking process of the pallet, and when the pallet moves up and down during the stacking and unstacking process, such as Figure 3 As shown, the mounting frame 4 provided inside the first side plate 1 can slide along the adapting slide groove 13 provided on the side wall of the first side plate 1 for a corresponding distance under the push of the first cylinder 6, and drive the first roller group 31 rotatably provided thereon to move so that it is placed at the corresponding notch 12 provided on the plate surface of the first side plate 1. At the same time, as shown in FIG. Figure 2As shown, the mounting seat 5 slides a corresponding distance along the adapting slide rails 14 provided at both ends of the first side plate 1 under the push of the second cylinder 7, and drives the second roller group 32 rotatably provided thereon to move to a corresponding distance along the adapting notch 12 provided on the surface of the first side plate 1 toward the inner direction of the first side plate 1 so that the second roller group 32 is flush with the surface of the first side plate 1, so that when the pallet moves up and down, the first roller group 31 placed at the notch 12 on the surface of the first side plate 1 can contact the side of the pallet, and the first roller group 31 at the corresponding position is adapted and rotated as the pallet moves, and when this kind of stacking plate When the stacked pallets in the frame structure 102 on the machine body 100 need to be centered, the second cylinder 7 can push the mounting seat 5 and the second roller group 32 rotatably arranged thereon to move to a corresponding distance in the direction of the second side plate 2 along the adapting slide rails 14 arranged at both ends of the first side plate 1.

With the arrangement of the guide assembly 3 on the first side plate 1, the position uniformity and stability of the pallet during the destacking process can be further improved, and the phenomenon of position offset, tilting or even falling off of the pallet can be effectively reduced. The structural arrangement of the first roller group 31 and the second roller group 32 in the guide assembly 3 can effectively reduce the degree of wear on the surface of the pallet and the main body of the baffle 1021 and the working noise thereof, and can cooperate with the first cylinder 6 and the second cylinder 6 according to the specific movement direction of the pallet during the destacking process. 7, the corresponding movement of the first roller group 31 and the second roller group 32 can effectively utilize the gap between the first side plate 1 and the side edge of the pallet, and center the misalignment of the stacked pallets. At the same time, the rotation of the first roller group 31 and the second roller group 32 can also play a certain guiding role on the pallet, further improving the stability and stacking efficiency of the pallet during the stacking process, and the setting of the guide assembly 3 can also further improve the functional diversity of the frame structure 102 on the main body 100 of the pallet stacking machine, and at the same time further improve the overall strength and working stability of the pallet centering device.
