[0052] In this embodiment, a plurality of the first pallet circulating conveyor line 2 - 1 and the second pallet circulating conveyor line 2 - 2 can be provided according to actual production output.

[0053] Working process: 1. The first AGV trolley 1 forks the materials (pallet + materials on the pallet) sent by the supplier into the supplier's material feeding conveyor 2-1-1, and the first appearance detection mechanism 2-6 detects and sends them to the first lifting and transplanting machine 2-1-3 at the exit of the supplier's material feeding conveyor 2-1-1. If the detection fails, the two first lifting and transplanting machines 2-1-3 work to exchange the unqualified materials to the supplier's pallet discharge conveyor 2-1-2 for delivery. If the detection passes, the depalletizing robot 2-3 grabs the materials on the pallet and puts them on the material conveying line 2-5.

[0054] 2. The stacker 3-4 in the vertical warehouse system 3 puts the empty pallets on the shelf 3-1 into the entrance of the vertical warehouse pallet outfeed conveyor 2-2-1, and removes the stacked pallets one by one through the pallet remover 2-10 and puts them into the vertical warehouse pallet outfeed conveyor 2-2-1, and then exchanges the empty pallets of the vertical warehouse to the second lift-transplanter 2-2-3 at the entrance of the vertical warehouse pallet infeed conveyor 2-2-2 through the second lift-transplanter 2-2-3 at the exit of the vertical warehouse pallet outfeed conveyor 2-2-1.

[0055] 3. The palletizing robot 2-4 grabs the materials on the material conveying line 2-5 and palletizes them on the vertical warehouse pallet on the second jacking and transplanting machine 2-2-3 at the entrance of the vertical warehouse pallet feeding conveyor 2-2-2.

[0056] 4. After palletizing is completed, the pallet feeding conveyor 2-2-2 of the vertical warehouse will send the palletized materials (materials + vertical warehouse pallets) to the appearance detection mechanism at the entrance of the pallet feeding conveyor for inspection. If qualified, they will be put into storage and placed on the shelf 3-1 by the stacker 3-4. If unqualified, they will be returned by the third lifting and transplanting machine and the third transmission roller for manual sorting. At the same time, the first lifting and transplanting machine 2-1-3 and the first transmission roller will exchange the supplier's empty pallets to the supplier's pallet discharge conveyor 2-1-2, and after being stacked by the stacking machine at the exit of the supplier's pallet discharge conveyor 2-1-2, they will be sent out by the first AGV trolley 1.

[0057] 5. When there is a floor that needs to be fed, the stacker 3-4 takes the material and places it on the raw material outlet conveyor line 3-2 of the corresponding floor for delivery. The second AGV trolley 4-1 takes the material and places it on the loading conveyor 4-2 for temporary storage. Then the mobile robot 4-3 takes the material and places it on the corresponding feeding conveyor line 4-4, and sends it to the unpacking machine 4-6 for unpacking. Finally, the material is quantitatively fed into the reactor 4-5 through the automatic control valve.

[0058] 6. After the feeding is completed, the empty pallets in the vertical warehouse on the feeding conveyor line 4-4 are sent to the second stacking machine 4-8 by the AGV car for stacking. After the stacking is completed, they are placed on the empty pallet warehouse conveyor line 3-3, sent to the vertical warehouse, and placed on the corresponding shelf 3-1 by the stacker 3-4.
