[0002] A pallet is a horizontal platform device used for packaging, stacking, handling and transporting goods and products as unit loads. As a type of packaging equipment similar to containers, pallets are now widely used in production, transportation, warehousing and circulation, and are considered one of the two key innovations in the logistics industry in the 20th century. Pallets are important loading, unloading, storage and transportation equipment in the logistics operation process, and they play a huge role in modern logistics when used in conjunction with forklifts.

DETAILED DESCRIPTION

[0032] The following is combined with Figure 1-4 The utility model is described in further detail.

[0033] Please refer to the attached figure in the instruction manual Figure 1-4 The utility model provides an embodiment of an automatic loading and unloading device for a material tray, comprising an equipment chassis 1, a second pneumatic rod 12 being connected above the equipment chassis 1, a tray bottom plate 11 being connected above the second pneumatic rod 12, the tray bottom plate 11 being automatically raised and lowered by cooperation with the second pneumatic rod 12, a first connecting spring 13 being connected above the tray bottom plate 11, a tray top plate 10 being connected above the first connecting spring 13, the tray top plate 10 being able to be fine-tuned in height by the first connecting spring 13 to improve adaptability, second connecting springs 14 being connected on both sides of the tray top plate 10, brackets 15 being connected on both sides of the second connecting spring 14, the brackets 15 being able to move left and right by cooperation with the second connecting spring 14;

[0034] The two sides of the equipment chassis 1 are also connected to support plates 6, the inner side of the support plate 6 is connected to the first pneumatic rod 5, and the inner side of the first pneumatic rod 5 is connected to the physical block 2. The physical block 2 cooperates with the first pneumatic rod 5 to drive the physical block 2 to move. The inside of the physical block 2 is connected to the working block 3, and the inside of the working block 3 is connected to the pointed cone head 4, which penetrates into the gap of the pallet through the pointed cone head 4 to separate different pallets. A fixed block 8 is also provided inside the physical block 2, and the center of the fixed block 8 is connected to an adjusting screw rod 16. The adjusting screw rod 16 is used to drive the floating plate 9 to move, and the position of the floating plate 9 is changed to limit different pallets. The other side of the adjusting screw rod 16 is connected to the floating plate 9. Automatic rods 17 are connected on both sides of the floating plate 9. The automatic rods 17 are used to limit the floating plate 9 to prevent it from moving.

[0035] Working principle: When in use, first, place the pallet that needs to be loaded and unloaded and cleaned above the pallet top plate 10, then rotate the adjusting screw 16 to make it threaded with the fixed block 8, changing the position of the floating plate 9 until it is close to both sides of the pallet. At this time, the floating plate 9 squeezes the bracket 15, making it move toward the inside of the pallet top plate 10 to ensure support for the pallet. Then, turn on the switch of the second pneumatic rod 12, so that the pallet bottom plate 11 begins to rise, driving the pallet top plate 10 and the pallet to rise to the pointed cone head. 4, the second pneumatic rod 12 stops working, and the first pneumatic rod 5 drives the physical block 2 to move toward the center. The rear working block 3 and the pointed cone head 4 penetrate into the gap between the trays. Because the pointed cone head 4 is conical, it will open the different trays, so that the top tray is separated from the tray below. If the gap is not completely aligned, the tray will be fine-tuned until the pointed cone head 4 penetrates the gap due to the first connecting spring 13 under the tray top plate 10. Finally, the top tray can be removed using a mechanical arm or other structures such as claws.

[0036] It should be noted that support plates 6 are symmetrically distributed on both sides of the equipment chassis 1. The support plates 6 form a pneumatic moving structure with the physical block 2 through the first pneumatic rod 5. The physical block 2 forms an automatic structure with the equipment chassis 1 through the movable shaft 7 below. The first pneumatic rod 5 is used to drive the physical block 2 to move, thereby automatically performing the pallet separation work.

[0037] It should be noted that the physical block 2 and the working block 3 are connected by hot melt connection. There are pointed cone heads 4 symmetrically distributed in the center of the working block 3. The pointed cone heads 4 are conical in structure. The pointed cone heads 4 are used to penetrate between the material trays to perform separation work.

[0038] It should be noted that the fixed blocks 8 are symmetrically distributed on both sides of the center of the equipment chassis 1. The connection between the fixed blocks 8 and the adjusting screw 16 is a threaded connection, and the connection between the adjusting screw 16 and the floating plate 9 is a rotating connection. By cooperating with the fixed blocks 8 and the adjusting screw 16, the position of the floating plate 9 is changed to limit and fix different material trays.

[0039] It should be noted that an anti-wear block is provided on the inner side of the floating plate 9, and automatic rods 17 are symmetrically distributed on both sides of the floating plate 9. The connection method between the automatic rod 17 and the fixed block 8 is automatic connection. The floating plate 9 is coordinated with the automatic rod 17 to stabilize the floating plate 9 and ensure its stability.

[0040] It should be noted that second connecting springs 14 are symmetrically distributed on both sides of the pallet top plate 10. The second connecting springs 14 and the bracket 15 are installed in an integrated manner. The connection between the bracket 15 and the pallet top plate 10 is automatic connection. The bracket 15 cooperates with the second connecting spring 14 to enable the pallet top plate 10 to change size.

[0041] It should be noted that the pallet bottom plate 11 and the second pneumatic rod 12 form an integrated lifting structure. The length and width of the pallet bottom plate 11 are smaller than the length and width of the pallet top plate 10. A pneumatic cylinder is provided under the second pneumatic rod 12. The pallet bottom plate 11 cooperates with the second pneumatic rod 12 to drive the pallet bottom plate 11 to automatically rise and fall, thereby continuously performing pallet loading and unloading operations.

[0042] It should be noted that the two sides of the first connecting spring 13 are fixedly connected to the tray bottom plate 11 and the tray top plate 10 respectively. The tray top plate 10 forms a spring reset structure with the tray bottom plate 11 through the first connecting spring 13. The inner side of the first connecting spring 13 is provided with a shock-absorbing damping. Through the cooperation of the first connecting spring 13 and the tray top plate 10, the tray top plate 10 can be fine-tuned and raised, thereby ensuring that the pointed cone head 4 can penetrate into the gap of the tray.
