[0002] With the continuous development of society, logistics has become a demand of people's lives. In order to meet customer needs, logistics is a process of planning, implementing and controlling the efficient and low-cost flow and storage of goods, service consumption and related information from the place of production to the place of consumption. A large number of workers are needed to handle the sorting, custody, loading and unloading of goods. The stacking device is the main storage and retrieval equipment in the automated warehousing system. It can walk horizontally and vertically in the aisles between the three-dimensional shelves according to instructions, and use forks to take out or store goods on the cargo grid, which can reduce the workload of personnel.

When the carrier rises, the carrier drives the fixed frame to move, and the fixed frame drives the driving gear to move through the rotating shaft. Because the driving gear is meshed with the longitudinal tooth plate, the driving gear rotates, and the driving gear drives the rotating shaft and the driven gear to rotate, so that the driven gear drives the load-bearing protective plate to move through the tooth groove, and the load-bearing protective plate is inserted into the bottom of the pallet;

[0021] The present invention has the following beneficial effects:

[0022] 1. A pallet stacker and a method of using the same. When a pallet needs to be transported, a servo motor drives a rotating rod to rotate, and the rotating rod drives a sprocket to rotate, so that the sprocket drives the chain to move, and the chain drives the carrier frame to move longitudinally by pulling the load-bearing lifting block, and the carrier frame moves longitudinally through the longitudinal guide rail to achieve smooth lifting and lowering, and can lift and lower goods and pallets. When the carrier frame rises, the carrier frame drives the fixed frame to move, and the fixed frame drives the driving gear to move through the rotating shaft. Because the driving gear is meshed with the longitudinal tooth plate, the driving gear rotates, and the driving gear drives the rotating shaft and the driven gear to rotate, so that the driven gear drives the load-bearing protective plate to move through the tooth groove, and the load-bearing protective plate is inserted into the bottom of the pallet, thereby achieving transmission stability and preventing the pallet from falling during transmission.

[0023] 2.

[0024] 3. A pallet stacker and a method for using the same. When the positioning clamping plate moves laterally, the positioning clamping plate drives the fixed box to move. Since the fixed slide bar is fixed, the lifting rod can pull the push slide column to slide on the triangular guide plate. The push slide column is guided by the triangular guide plate to enable the push slide column to squeeze the push plate, so that the push plate moves with the hinged positioning rod as the axis. The push plate pulls the convex slide block to slide in the concave slide block through the hinge, so that the concave slide block drives the rubber clamping plate to fix and clamp the material on the pallet, thereby ensuring the safety and stability of the operation process.

[0025] 4. A pallet stacker and a method of using the same, after the forklift clamps the box, the cylinder is started, the cylinder pushes the toothed plate to move, the toothed plate drives the gear to rotate with the hinge rod as the axis, so that the gear drives the load-bearing plate to rotate through the hinge rod, and the load-bearing plate is inserted into the bottom of the pallet, which makes it more convenient to load and unload materials, and effectively ensures the accurate storage and retrieval of goods.

[0026] 5. A pallet stacker and a method of using the same. When the tooth plate moves, the tooth plate pushes the extrusion plate to move. The extrusion plate squeezes the gas inside the extrusion box. The squeezed gas enters the lifting and fixing block, so that the lifting and fixing block moves outward in the extrusion box. The lifting and fixing block squeezes and fixes the outside of the pallet, thereby improving the safety of the pallet and goods during movement, reducing the occurrence of dangerous accidents such as skewing and falling of goods during storage and retrieval, and thus ensuring the safety of the stacker in picking up and releasing goods.

When the positioning clamping plate 406 moves laterally, the positioning clamping plate 406 drives the fixed box 502 to move. Because the fixed slide bar 501 is fixed, the lifting rod 509 can pull the push slide column 510 to slide on the triangular guide plate 511. The push slide column 510 can be guided by the triangular guide plate 511 to make the push slide column 510 squeeze the push plate 504, so that the push plate 504 moves with the hinged positioning rod 503 as the axis. The push plate 504 pulls the convex slider 506 to slide in the concave slide plate 507 through the hinge 505, so that the concave slide plate 507 drives the rubber clamping plate 508 to fix and clamp the materials on the pallet 11, ensuring the safety and stability of the operation process;

When the carrier (207) rises, the carrier (207) drives the fixed The fixed frame (304) moves, and the fixed frame (304) drives the driving gear (302) to move through the rotating shaft (303). Since the driving gear (302) is meshed with the longitudinal tooth plate (301), the driving gear (302) rotates, and the driving gear (302) drives the rotating shaft (303) and the driven gear (305) to rotate, so that the driven gear (305) drives the load-bearing protection plate (306) to move through the tooth groove (307), and the load-bearing protection plate (306) is inserted into the bottom of the tray (11); S2: When the pallet (11) needs to be moved, the drive motor (401) is started, the drive motor (401) drives the bidirectional threaded rod (402) to rotate, the bidirectional threaded rod (402) drives the positioning block (403) to move, and the positioning block (403) moves laterally through the transverse guide rail (405), so that the positioning block (403) drives the positioning clamping plate (406) and the fork cargo clamping box (407) to position and clamp the pallet (11); S3: When the positioning clamping plate (406) moves laterally, the positioning clamping plate (406) drives the fixed box (502) to move. Since the fixed slide bar (501) is fixed, the lifting rod (509) can pull the push slide column (510) to slide on the triangular guide plate (511). The push slide column (510) can be guided by the triangular guide plate (511) to squeeze the push plate (504), so that the push plate (504) moves with the hinged positioning rod (503) as the axis. The push plate (504) pulls the convex slider (506) to slide in the concave slide plate (507) through the hinge (505), so that the concave slide plate (507) drives the rubber clamping plate (508) to fix and clamp the material on the pallet (11); S4: After the forklift clamping box (407) clamps, the cylinder (601) is started, and the cylinder (601) pushes the tooth plate (602) to move, and the tooth plate (602) drives the gear (605) to rotate around the hinge rod (604), so that the gear (605) drives the load-bearing plate (606) to rotate through the hinge rod (604), and the load-bearing plate (606) is inserted into the bottom of the pallet (11). When the tooth plate (602) moves, the tooth plate (602) pushes the squeezing plate (702) to move, and the squeezing plate (702) squeezes the gas inside the squeezing box (701), and the squeezed gas enters the lifting and fixing block (704), so that the lifting and fixing block (704) moves outward in the squeezing box (701), and the lifting and fixing block (704) squeezes and fixes the outside of the pallet (11).
