The loading lifting seat 302 is installed at the bottom of the loading lifting platform and can be lifted upward into the loading bin 301.

[0042] Specifically, when the material tray is loaded, the loading lifting seat 302 rises upward and contacts the material tray to support the material tray, and then the opening switch assembly opens, allowing the material tray to fall from the bottom of the loading bin 301, and then the loading lifting seat 302 descends, driving the lowest material tray to fall onto the loading lifting platform, and at the same time, when a material tray falls from the loading bin 301, the opening switch assembly will automatically close, allowing the remaining material trays to continue to remain in the loading bin 301.

[0043] Preferably, in this embodiment, the opening switch assembly includes two groups of switch devices arranged symmetrically, and the switch device includes a switch cylinder 303 and a switch plate 304. The switch cylinder 303 is horizontally installed on one side of the bottom of the loading bin 301, and the switch plate 304 is connected to the piston rod of the switch cylinder 303 and can extend into the bottom of the bin rack;

[0044] Specifically, when the material tray needs to fall, the switch cylinder 303 is actuated to make the switch plate 304 extend from the first opening at the bottom of the loading bin 301, and the material tray can fall from the first opening, completing the material tray unloading, and the switch cylinder 303 is actuated again to make the switch plate 304 extend into the first opening, closing the first opening, thereby ensuring that the material tray in the loading bin 301 continues to stay in the loading bin 301.

The unloading lifting seat 402 is installed at the bottom of the unloading lifting platform and can be lifted upward into the unloading bin 401.

[0048] Specifically, when the material tray is being unloaded and stacked, the material tray pushed onto the unloading lifting platform will be lifted by the unloading lifting seat 402, so that the material tray moves upward and contacts with the material tray in the unloading bin 401 and is driven to move upward together. Then the material tray on the unloading lifting platform pushes open the automatic anti-fall component 403, so that it is located above the automatic anti-fall component 403. Finally, the unloading lifting seat 402 descends, and the material tray is held against the automatic anti-fall component 403 and is located in the unloading bin 401, completing the unloading and stacking.

The limiting rod is installed on the lower outer side of the anti-falling block, so that the anti-falling block can only flip upwards but not downwards.

[0050] Specifically, when the material tray is lifted up by the lower material lifting seat 402, the material tray can automatically push open the anti-fall block, causing the anti-fall block to rotate upward. After the material tray is completely raised above the anti-fall block, the anti-fall block is automatically flipped downward and returned to its original position under the influence of gravity, supporting the material tray. Under the action of the limit rod, it can ensure that the anti-fall block will not rotate downward, thereby having a supporting effect.

[0053] Specifically, when the material tray at the material receiving conveyor belt 501 is unloading, the lifting platform 502 first lifts the material tray, and then the two guide cylinders 504 are actuated to drive the two waiting material guide shafts 503 to move to the bottom of the material tray, and the two waiting material guide shafts 503 are aligned with the two unloading guide shafts 404, and then the unloading and pushing mechanism pushes the material tray to move for unloading.
