[0026] In this embodiment, firstly, the worker stacks empty pallets on the front-end feeding assembly 3 of the hopper. The front-end feeding assembly 3 and the first bottom limiting mechanism work together to place each empty pallet onto the blowing plate conveyor assembly 2 in sequence. The blowing plate conveyor assembly 2 then sequentially transports the pallets to the positions of the hopper center picking assembly 4 and the second hopper feeding assembly 5. When a pallet passes the hopper center picking assembly 4, it is lifted up, and the blowing plate conveyor assembly 2 stops operating. The robotic arm then sequentially places the workpiece material into the pallet for loading. After the pallet is full, the hopper center picking assembly 4 lowers the pallet onto the blowing plate conveyor assembly 5. On the feeding assembly 2, the material is then conveyed to the second hopper unloading assembly 5. At this time, the second bottom limiting mechanism retracts, and the second hopper unloading assembly 5 is controlled to lift the full pallet upward. When it rises to a suitable position, the second bottom limiting mechanism is controlled to extend and fix the bottom pallet. The above process is repeated to achieve stable conveying of stacked empty pallets to the blowing tray conveyor assembly 2 for loading and processing.
