[0029] The following is a further detailed description of the present invention in conjunction with specific embodiments:

[0030] like Figure 1 As shown, a pallet 6 stacking device includes a supporting frame 1, a driving mechanism 2, a lifting bracket 3, a first bracket 4, and a second bracket 5. A slide rail 15 is provided on the supporting frame 1, and the lifting bracket 3 is connected to the slide rail 15. Driven by the driving mechanism 2, it completes rising and falling on the slide rail 15. A roller assembly 16 is also provided on the lifting bracket 3, which moves the pallet 6 to a suitable position through the roller assembly 16. When the lifting bracket 3 moves up, it contacts the pallet 7 on the first bracket 4 and the second bracket 5, so that the pallet 7 rotates away from the pallet 6. When the pallet 6 moves to a certain position, the pallet 7 is no longer in contact with the pallet 6 and rotates back to the initial position under the action of gravity. Then the lifting bracket 3 starts to descend under the drive mechanism 2, and places the pallet 6 on the pallet 7. When the roller assembly 16 transports the next pallet 6, the above steps are repeated, thereby completing the stacking of the pallets 6, keeping each pallet 6 in close contact with the previous pallet 6 when moving upward, increasing the number of stacking and improving the transportation efficiency.

[0031] In this embodiment, Figure 2As shown, the pallet 7 includes a supporting surface 71 and an abutting surface 72. The first bracket 4 and the second bracket 5 are both provided with a limit rod 8 and are close to the pallet 7. The pallet 7 rotates under the action of gravity, so that the abutting surface 72 contacts the limit rod 8, limiting the continued rotation of the pallet 7. At this time, the supporting surfaces 71 of the two pallets 7 are on the same horizontal plane and parallel to the pallet 6. When the pallet 6 is lifted and placed on the supporting surface 71, the pallet 6 is in a horizontal state. When the supporting surfaces 71 of the two pallets 7 are on the same horizontal plane, it can ensure that the weight distribution of the goods on the pallet 6 is more even, thereby avoiding tilting or damage of the pallet 6 due to uneven weight. At the same time, it is also easier to stack the pallets 6, and the stacking height is more stable, which helps to maximize the space utilization of warehouses or transport vehicles.

[0032] Specifically, when the abutment surface 72 contacts the limit rod 8, the length of the pallet 6 along the transport direction is less than the distance between the two abutment surfaces 72, and greater than the distance between the two support plates 7 close to one end of the pallet 6, so that the pallet 6 can be rotated when lifted by the lifting bracket 3, and the pallet 6 will not be unable to be lifted or placed on the support surface 71 due to being too long or too short, thereby resulting in the inability to complete the stacking of the pallet 6.

[0033] like Figure 3-Figure 4 As shown, in order to facilitate the positioning and stacking of the pallet 6, support members 10 are installed above the four corners of the pallet 6, and positioning members 11 are set between the support members 10 at a pair of corners and the pallet 6. The top of the support member 10 contacts the bottom of the previous pallet 6 to lift the pallet 6, so that the pallet 6 can form a stable support structure when stacked, effectively preventing the pallet 6 from tilting or collapsing due to unstable center of gravity or external force. At the same time, the support member 10 directly contacts the bottom surface of the previous pallet 6, reducing the direct contact area between the pallets 6, thereby reducing the wear caused by friction and extending the service life of the pallet 6. When the top of the support member 10 contacts the bottom of the pallet 6 and lifts it, the pallet 7 is forced to rotate, and the pallet 7 does not contact the pallet 6 during the rotation process, so that the pallet 6 maintains stability during the stacking process and prevents the pallet 7 from contacting the pallet 6. The force on the pallet 6 is offset due to different force directions, thereby causing the pallet 6 to tip over and be damaged.

[0034] Among them, the positioning member 11 includes a positioning plate 111 and a positioning column 112. A positioning hole 12 is provided on the bottom surface of the pallet 6. The top end of the positioning column 112 passes through the support member 10 and is located above the support member 10. When two pallets 6 are stacked together, the positioning column 112 will be inserted into the positioning hole 12. The cooperation between the positioning column 112 and the positioning hole 12 can ensure that the pallet 6 will not be offset in the horizontal or vertical direction during the stacking process, thereby maintaining the overall stability. During transportation or storage, the close cooperation between the positioning column 112 and the positioning hole 12 can reduce the vibration of the pallet 6 caused by various external forces. At the same time, the cooperation between the positioning column 112 and the positioning hole 12 can ensure the stacking accuracy of the pallet 6, avoid damage to the pallet 6 due to misalignment, and enable the pallets 6 to be stacked tightly together, reducing gaps and waste during the stacking process, thereby optimizing the space utilization of warehouses or transport vehicles.

[0035] Furthermore, the pallet 6 is provided with guide rails 9 on both sides perpendicular to the transport direction and in contact with the corresponding side surfaces of the pallet 6. The guide rails 9 can ensure that the pallet 6 moves along a predetermined direction during transportation, preventing the pallet 6 from being offset or tilted during transportation, thereby improving the stability of transportation. At the same time, it enables the pallet 6 to be accurately transported to the designated position, facilitating the subsequent stacking of pallets 6. A buffer pad is also provided on the side of the second bracket 5 close to the pallet 6. When the pallet 6 moves into place, the impact of the pallet 6 is reduced to prevent the pallet 6 from being damaged by impact.

[0036] like Figure 5-Figure 6 As shown, in order to improve the stability of the stacking of pallets 6 and prevent stacking deviation, a detection switch 13 is provided on the support frame 1, and corresponds to the position of the metal block on the bottom of the pallet 6. When the detection switch detects the metal block, the pallet 6 moves into place and the roller assembly 16 stops running for stacking. At the same time, a plurality of proximity switches 14 are provided on the support frame 1 for detecting the moving position of the lifting bracket 3 and the stacking quantity of the pallets 6. The position of the lifting bracket 3 can be accurately controlled to achieve high efficiency and high quantity stacking.

[0037] The implementation principle of this embodiment is as follows:

[0038] When stacking pallets 6, the roller assembly 16 transports the pallet 6 to be stacked along the guide rail 9. When the metal block on the bottom of the pallet 6 corresponds to the position of the detection switch 13, the detection switch 13 detects that the pallet 6 has moved to the appropriate position. Subsequently, the driving mechanism 2 drives the lifting bracket 3 to slide on the slide rail 15 to lift the pallet 6 upward. When it contacts the pallet 6, the pallet 6 rotates and the pallet 6 continues to move until the pallet 6 is no longer in contact with the pallet 7. The pallet 7 returns to its initial position under the action of gravity. The driving mechanism 2 then drives the lifting bracket 3 to move downward, places the pallet 6 on the pallet 7, and moves the roller assembly 16 to its initial position. The roller assembly 16 transports another pallet 6 and repeats the above process until the stacking of the pallets 6 is completed. Finally, the multiple pallets 6 after stacking are transported as a whole to a height exceeding the pallet 7 to prepare for the next step of transportation.
