[0002] Currently, in the plastic and rubber product industries, semi-finished products are mostly stored in 1m 3 material frames. After the semi-finished products are taken off the production line, they need to be transferred or stored in the warehouse. To save the number of handling times and storage space, usually 2-4 layers of material frames need to be stacked. Currently, the stacking of material frames is all operated by manually driving a forklift. Since a dust-proof plastic film needs to be laid on the material frames, the line of sight for manual stacking is not good, the alignment is difficult, and the stacking efficiency is low. Usually, it takes 50 seconds to 60 seconds for a skilled forklift operator to stack one layer of material frames, and there is also a potential safety hazard of the material frames falling during transfer due to staggered stacking.
