The goods are placed on the material tray and are sent to the feeding frame 1 of the feeding area. Have the two-dimensional code on the goods, the design has two-dimensional code scanning rifle on stack AGV2, can discern the goods that are located on work or material rest 1. Shuttle AGVs 3 are provided on rack 4. Shuttle AGV3 waits at the loading port of rack 4, i.e., the far left end of fig. 1. Warehousing stacking AGV2, first driving to the upper rack 1, completing material taking action through the bidirectional fork 5, and then driving to the system specified warehousing position. Palletized loads are placed on shuttle AGVs 3 by stacking the bidirectional forks 5 of AGVs 2. The shuttle AGV3 transfers the pallet load to the delivery end of the lane of the rack 4, i.e., the rightmost end in fig. 1, and places the pallet load on the rack 4 via the elevator. Shuttle AGV3 returns to the far left end of rack 4. When the tape pallet is stored again, the shuttle AGV3 repeats the above operation until the rack 4 lane is full of goods.

After the goods in the goods shelf 4 where the shuttle AGV3 is located are fully arranged, the goods shelf of the shuttle AGV3 is changed through the bidirectional fork 5 of the warehousing stacking AGV2, the shuttle AGV3 is transferred to the empty goods shelf, and preparation is made for next warehousing of the material carrying tray.

Similarly, when the belt material tray is delivered from the warehouse, the shuttle AGV3 at the other end is matched with the delivery stacking AGV2 to complete the process. First, after the shuttle AGV3 transfers the tape trays to the delivery end of the rack 4, i.e., the rightmost end in fig. 1, the delivery stack AGV2 transfers the tape trays to the loading rack 1 at the other end. Similarly, when the belt material trays on the goods way are completely unloaded, the shuttle AGV3 is transferred to other roadways with belt material trays by the warehouse-out stacking AGV 2.

The laser navigation 7 and the laser obstacle avoidance radar 9 can be arranged without laying a track, automatic identification of the stacking AGV2 is achieved, and the controller controls the stacking AGV2 to automatically stop after encountering an obstacle. Controllers are arranged in the traveling unit 10 and the shuttle AGVs 3, and the stacking AGV2 and the shuttle AGV3 are connected with an upper computer material control system through wireless, so that the position of each goods box on the shelf 4 can be clearly found.

The jacking oil cylinder 16 drives the inner frame 27 to move upwards, and then the chain wheel 21 rises, because one end of the chain 17 is fixed on the outer frame 14, and the other end of the chain 17 drives the sliding frame 13 to rise, the rising action of the sliding frame 13 is realized, and the descending process is opposite. The corresponding guide bearings and guide rails are matched to realize the functions of limiting the inner frame 27 and the sliding frame 13 in the lifting process and reducing the resistance. The bidirectional fork 5 realizes bidirectional fork loading of goods.
