[0002] When goods are stored in an automated warehouse, they are often placed on pallets. Since the pallets used in the warehouse are self-use turnover pallets, when the goods are shipped, they need to be transferred to the shipping pallets for shipment, so the pallets on which the goods are placed need to be replaced;
[0003] Currently available pallet changing equipment mostly uses flipping or clamping methods to change pallets for palletized goods. Flipping pallet changing equipment requires the goods to be inverted or flipped more than 90 degrees to achieve pallet changing operations. This equipment is not suitable for goods that do not allow flipping or inversion, or for pallet types that are light on the top and heavy on the bottom. Clamping pallet changing equipment will apply squeezing force to the side of the goods, and lift the goods through the friction force generated by the squeezing, and then perform the pallet changing operation. However, this method is prone to damage to fragile and deformable goods. Summary of the invention

[0020] See also Figure 1-Figure 7The utility model provides the following technical solutions: it includes a fixed frame 7, a pushing assembly 1 is provided on one side of the fixed frame 7, the pushing assembly 1 includes a pushing cylinder 11, a base 12, a scissors fork mechanism 13 and a pushing plate 14, the base 12 is slidably connected to the fixed frame 7, the pushing cylinder 11 is fixedly connected between the base 12 and the scissors fork mechanism 13, one end of the scissors fork mechanism 13 is fixedly connected to the pushing plate 14, a cylinder stop assembly 2 is provided on one side of the pushing assembly 1, a wire body lifting mechanism 3 is installed on one side of the fixed frame 7, a side support plate 4 is provided on one side of the pushing assembly 1, a side baffle 5 is provided above the side support plate 4, the side baffle 5 is fixedly connected to the fixed frame 7, a conveyor line 6 is installed on the inner side of the fixed frame 7, and a first pallet 8 and a second pallet 9 are slidably connected to the top of the conveyor line 6.
[0021] In this embodiment: the fixed frame 7 is used to support and connect various components, so that the replacement of the cargo pallet is completed through the cooperation of various components. The pushing assembly 1 provided on one side of the fixed frame 7 is used to push the cargo. The pushing cylinder 11 included in the pushing assembly 1 is used to extend the scissor fork mechanism 13, so as to achieve the purpose of pushing the pushing plate 14 through the scissor fork mechanism 13. The base 12 is used to provide support for the pushing cylinder 11, the scissor fork mechanism 13 and the pushing plate 14. The base 12 slides on one side of the fixed frame 7, so that when the cargo follows the second pallet 9 to move on the surface of the conveyor line 6, the cargo will correspond to the position of the pushing assembly 1. The pushing assembly 1 can reach a position corresponding to the horizontal direction of the cargo by vertical sliding, and then the pushing cylinder 11 will push the scissor fork mechanism 13 to expand, so that the scissor fork mechanism 13 drives the pushing plate 14 to move, and the pushing plate 14 will push the cargo after contacting the cargo, and before pushing the cargo, the conveyor line 6 is divided into two parts, wherein the first pallet 8 will be moved to the part below the side support plate 4, and then the line body lifting mechanism 3 will drive the first pallet 8 to move to the part below the side support plate 4. The conveyor line 6 at the position of the plate 8 moves vertically, so that the first tray 8 moves to the bottom of the side support plate 4. The horizontal height of the side support plate 4 is the same as that of the second tray 9, so that when the pushing component 1 pushes the goods to move, the goods will reach the top of the side support plate 4. Since the top of the side support plate 4 is relatively smooth, the goods will not generate a large amount of friction at the top of the side support plate 4 when being pushed, thereby avoiding damage to the goods. When the goods are pushed by the pushing component 1, the goods will be blocked by the side baffle 5, thereby ensuring that the position of the goods when reaching the top of the side support plate 4 will not deviate. When the goods reach the top of the side support plate 4, the side support plate 4 will be pulled out from the bottom of the goods. When the side support plate 4 is pulled out, the side baffle 5 will block the goods, so that the goods can fall stably on the top of the first tray 8. At this time, the conveyor line 6 will drive the first tray 8 and the goods as well as the second tray 9 to be removed in the direction indicated in the figure description five. Before the goods move, the pushing component 1 will move on one side of the fixed frame 7, thereby making way for the movement of the goods and ensuring that the goods can be moved out.

When the side support plate 4 needs to move horizontally, the stop device 21 will first move vertically. At this time, the side support plate 4 will slide on the inside of the stop device 21, so that the sliding of the side support plate 4 will be guided by the stop device 21 to ensure that the side support plate 4 will not deviate during movement. The fixed bracket 22 is used to provide support for the stop device 21 and other components.
[0023] The hydraulic cylinder 23 is located below the stopping device 21, and a linear guide rail 24 is installed on one side of the hydraulic cylinder 23. The output end of the hydraulic cylinder 23 is fixedly connected to the slider 25, and the slider 25 slides on the outside of the linear guide rail 24. The stopping device 21 is fixedly connected to the top of the slider 25; the hydraulic cylinder 23 is used to drive the slider 25 to move, and the slider 25 will slide on the outside of the linear guide rail 24 when moving, and the linear guide rail 24 will guide the movement of the slider 25. The stopping device 21 is installed on the top of the slider 25, so that the stopping device 21 can move to the outside position of the bottom end of the side support plate 4, thereby ensuring the guiding effect on the movement of the side support plate 4.
