[0003] Existing loading sites, such as chemical, feed, cement, etc., are mostly manually loaded. Due to the harsh on-site environment and heavy dust, there are serious health hazards to the on-site loaders. At the same time, the production cost and labor cost of the enterprise are relatively large. Since the stacking and stacking work is mostly done by manpower and forklifts, not only is the labor intensity high, but the loading efficiency is also low. Summary of the invention

[0004] The purpose of the present invention is to solve the deficiencies of the prior art and provide a multi-station packaging device which saves manpower, has a high degree of automation and high loading efficiency.

[0005] The technical solution adopted by the present invention to solve the above technical problems is:

In the above technical scheme, the adjacent material bags on the first transport structure are sequentially transferred to the second transport structure and the third transport structure by the sub-packaging structure, and then the material bags are grabbed from the second transport structure and the third transport structure by the grabbing structure and placed on the truck. Two grabbing structures are arranged in parallel between the second transport structure and the third transport structure, and each grabbing structure is provided with two mechanical claws. The four mechanical claws cooperate with each other according to the preset grabbing and placing speeds to transfer the material bags on the second transport structure and the third transport structure to the truck, which greatly improves the transfer efficiency of the material bags. The rotating structure forms a Y-shaped sub-packaging structure with the first transition structure and the second transition structure. The rotating structure sequentially diverts the adjacent material bags to the first transition structure and the second transition structure. When sub-packaging, the material bags are transferred from the transport structure to the sub-packaging structure, and the rotating structure of the sub-packaging structure is sequentially turned to the first transition structure and the second transition structure, so that the adjacent material bags are sequentially transferred to the first transition structure and the second transition structure, and then transferred from the first transition structure and the second transition structure to the second transport structure and the third transport structure, and finally the grabbing structure grabs the material bags from the second transport structure and the third transport structure and places the material bags on the truck.
