In general, the palletizing system transfers pallets to a loading position by a conveying conveyor, and then automatically loads the goods on the pallets using a robot. In the field where the palletizing system is applied, a large amount of rectangular parallelepiped products are produced. It is mainly applied to the field where regular palletizing pattern should be provided in the high speed line. In other words, it is widely used to load lightweight materials such as toilet paper, milk and confectionery boxes, and according to the order of the orderer, various standard goods are loaded into various pallets according to the warehouse standard, etc. It was to be discharged to the outside through the wrapping line, the bending line and the discharge line.
