[0030] Refer to Figures 3 - 5As shown, the full pallet bin 2 and the empty pallet bin 3 both include a bin door 21, a bin bottom plate 22, several pallet limit plates 23 and a lifting assembly 24. The bin door 21 is fixedly arranged at one end of the bin bottom plate 22. The bin bottom plate 22 is slidably connected to the bracket 1. The lower end of the pallet limit plate 23 is fixedly arranged on the bin bottom plate 22, and the pallet limit plate 23 is perpendicular to the bin bottom plate 22. The several pallet limit plates 23 enclose a rectangular frame, and a stack of pallets is arranged within the range enclosed by the several pallet limit plates 23. The lifting assembly 24 is arranged on the bracket 1. There is a stack of pallets on the lifting assembly 24, and the lifting assembly 24 is used to lift the pallets upward. A slide rail mounting plate 11 is arranged on the bottom surface of the bracket 1. A drawer-type slide rail 12 is arranged between the slide rail mounting plate 11 and the bin bottom plate 22. The drawer-type slide rail 12 is used for the bin bottom plate 22 to slide on the bracket 1. By arranging the drawer-type slide rail 12, it is convenient to push the bin enclosed by the several pallet limit plates 23 in or out. In the full pallet bin 2, when feeding, the lifting assembly 24 drives the pallets to rise layer by layer according to the height, so that the pallets to be used are always kept at a certain height at the top. When the empty pallet bin 3 receives the empty pallets, as pallets are continuously placed on the bin bottom plate 22, the lifting assembly 24 drives the bin bottom plate 22 to descend layer by layer.

The two positioning mechanisms 5 are respectively located on both sides of two opposite sides of the pallet in the full pallet bin 2. The positioning mechanism 5 includes a positioning driving cylinder 51 and a positioning push plate 52. The positioning driving cylinder 51 is fixedly arranged on the bracket 1. The positioning push plate 52 is connected to the piston rod of the positioning driving cylinder 51.

There are positioning mechanisms 5 on two opposite sides of the pallet with a rectangular cross-section. When the piston rod of the positioning driving cylinder 51 extends, it can push the positioning push plate 52 to press against the side of the pallet, so as to keep the full pallet being fed in the full pallet bin 2 stable.

[0033] Refer to Figure 5As shown, the handling mechanism 6 includes a handling drive cylinder 61, an adapter plate 62, a nozzle mounting plate 63, and a plurality of handling nozzles 64. The handling drive cylinder 61 is fixedly arranged on the bracket 1. The nozzle mounting plate 63 is connected to the handling drive cylinder 61 through the adapter plate 62. The plurality of handling nozzles 64 are arranged on the nozzle mounting plate 63, and the plurality of handling nozzles 64 are used for adsorbing the trays. The nozzle mounting plate 63 is a U-shaped plate, and handling nozzles 64 are arranged on both opposite sides of the nozzle mounting plate 63.

[0034] Referring to Figure 6 As shown, the manipulator mechanism 4 includes a manipulator 41, a mounting plate 42, and a plurality of adsorption components 43. The mounting plate 42 is connected to the manipulator 41. The plurality of adsorption components 43 are arranged in a row on the mounting plate 42.

The slider 433 is fixedly connected to the moving plate 434, and the slider 433 is slidably connected to the linear guide rail 432. The output end of the adsorption drive cylinder 431 is connected to the moving plate 434. The second nozzle 435 is arranged on the moving plate 434. The adsorption drive cylinder 431 drives the moving plate 434 to move to enable the second nozzle 435 to adsorb the materials on the trays in the full-material tray bin 2.

[0036] For the Tray disk loading and unloading device of the present utility model, mainly through the structure of the Tray disk itself, the Tray disks are self-positioned when two are stacked. In addition, in order to improve the stability of a stack of full-material Tray disks, for the topmost Tray disk of multiple stacked full-material Tray disks, an empty Tray disk is added to restrict the shaking of the products in the topmost full-material Tray disk. When taking the products, the manipulator 41 moves the second nozzle 435 above the products and sucks them suspended in the air to avoid the loading and unloading device pressing the Tray disk, thereby affecting other products in the Tray disk. The same applies to unloading. The Tray disk is loaded by a hoist, and the loading and unloading device directly takes the materials from above the full-material Tray disk bin, avoiding the handling of the full-material Tray disk. After a tray of materials is taken out, the handling device transports the empty Tray disk to the empty material tray bin 3. After the hoist lifts the full-material Tray disk, the loading and unloading device continues to take the materials suspended in the air. The influence on material taking and unloading caused by product shaking can be avoided.

[0037] Principle description of the Tray disk loading and unloading device of the present utility model:

[0038] During loading:

[0039] 1. Manually place a stack of full Tray trays into the full tray bin 2, and then the elevator lifts the Tray trays to the picking position.

[0040] 2. The handling mechanism 6 takes away the topmost empty Tray tray, and the lifting assembly 24 and the positioning mechanism 5 cooperate to position the topmost Tray tray. The manipulator mechanism 4 sequentially picks up materials suspended above the products.

[0041] 3. After all the products in the tray are picked up, the handling mechanism 6 transports the empty Tray tray to the empty tray bin 3. The lifting assembly 24 in the empty tray bin 3 descends. After the empty tray bin 3 is full, it is manually removed.

[0042] During discharging:

[0043] 1. Manually place a stack of empty Tray trays into the empty tray bin 3, and then the lifting assembly 24 of the empty tray bin 3 lifts the Tray trays to the handling position.

[0044] 2. The handling mechanism 6 transports the empty Tray tray to the discharging position, and the manipulator mechanism 4 sequentially discharges materials suspended above the products.

[0045] 3. After the tray is full, the lifting assembly 24 descends, and step 2 is executed until the last Tray tray is placed at the discharging position and no more discharging is performed, and then it is manually removed.

[0046] Obviously, the above embodiments are merely examples for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present utility model.
