DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-4 A pallet automatic stacking device comprises a bottom bracket 1, driving devices 2 are arranged on both sides of the bottom bracket 1, bottom plates 3 are connected to the driving ends of the two driving devices 2, guide rods 4 are connected to both ends of each bottom plate 3, the top ends of every two adjacent guide rods 4 are connected to the same top plate 5, two rotating seats 6 are arranged on each top plate 5, a rotating support plate 7 is rotatably installed in each rotating seat 6, a limiting block 8 is arranged on the rotating seat 6, and the limiting block 8 is located below the rotating support plate 7, and four stop vertical plates 9 are arranged on the bottom bracket 1, and each stop vertical plate 9 is respectively located below each corresponding rotating support plate 7.

[0022] The device is used in conjunction with a conveyor line, and the pallet is transported to the stacking station through the conveyor line. At the initial position, the driving shaft of the driving device 2 is in a retracted state, the top plate 5 is in a low position, and the rotating pallet 7 is in an upward tilted state under the action of the stopper vertical plate 9. The first pallet is transported to the pallet stacking station through the conveyor line; the driving shaft of the driving device 2 extends, driving the bottom plate 3, the guide rod 4 and the top plate 5 to rise, and the rotating seat 6 follows the rise, and the rotating pallet 7 is located below the first pallet. The top plate 5 continues to rise so that the rotating pallet 7 contacts the bottom end of the pallet, and the rotating pallet 7 is limited in its downward rotation through the limiting support of the limiting block 8, and The first pallet is lifted up and separated from the conveyor line, and the subsequent pallets are conveyed to the pallet stacking station through the conveyor line. The driving shaft of the driving device 2 is retracted, driving the bottom plate 3, guide rod 4 and top plate 5 to descend, and the rotating seat 6 drives the rotating pallet 7 to descend. At this time, the rotating pallet 7 contacts the side of the pallet located below, so that the rotating pallet 7 rotates upward and is in an upward tilted state again under the support of the stop plate 9, so that the rotating pallet 7 is located on the outside of the pallet when it is tilted. At this time, the rotating pallet 7 follows the top plate 5 to return to the low position again, and the stacking operation of the two pallets is completed. The above actions are repeated to complete the stacking function of several pallets.

[0023] Specifically, in this embodiment, two parallel guide groove brackets 10 are provided on the bottom bracket 1, and guide grooves 11 are opened on both ends of each guide groove bracket 10. Each guide rod 4 is slidably adapted in the guide groove 11 at the corresponding position, and the guide groove 11 provides vertical lifting space for the guide rod 4, as well as stability during the lifting process.

[0024] Specifically, in this embodiment, an angle iron 12 is provided at the connection between the upper end of the bottom plate 3 and the side of the guide rod 4 , and the angle iron 12 improves the stability and firmness of the connection between the bottom plate 3 and the guide rod 4 .

[0025] Specifically, in this embodiment, two columns 13 are connected between the bottom plate 3 and the top plate 5. Each column 13 is located directly below each corresponding rotating seat 6. The columns 13 provide support for the rotating seat 6 and the rotating support plate 7. The top plate 5 is located at the connection portion of the rotating seat 6 to bear the weight of multiple pallets.

[0026] Specifically, in this embodiment, a shaft 14 is hinged inside the rotating seat 6, and the rotating support plate 7 is connected to the upper end of the shaft 14, so that the rotating support plate 7 can rotate while improving the integrity between the rotating seat 6 and the rotating support plate 7.

[0027] Specifically, in this embodiment, one end of the rotating seat 6 extends outward, and the limit block 8 is arranged on the extended portion, which is far away from the shaft body 14, ensuring that the shaft body 14 and the rotating support plate 7 can rotate smoothly while allowing the limit block 8 to smoothly provide bottom support for the rotating support plate 7.

[0028] Specifically, in the present embodiment, a tension spring 15 is connected between the side of the rotating seat 6 and the side of the rotating support plate 7. When the rotating support plate 7 is in an upwardly tilted state, the tension spring 15 is in a stretched state. As a result, when the rotating support plate 7 rises with the rotating seat 6, it is automatically restored to a horizontal state under the action of the elastic force of the tension spring 15, thereby facilitating the rotating support plate 7 to lift the tray.

[0029] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
