The work aims to research on how to quickly and accurately place the packages in the desired location at the end of the automatic packing line. Vacuum sucker lifting technology for stacking was used. Lifting system was established. Grabbing, handling, moving evenly, lifting & dropping and other dynamic operations of packaging box were completed. Air-permeability, vacuum and time model were established to determine the relationship of all parameters of running system. Vacuum pumping speed (i.e. maximum vacuum to be achieved) could determine the maximum air permeability of carton; on the contrary, when the air permeability of carton was known, the minimum vacuum required could be determined. With vacuum sucker lifting technology, non-breathable coated corrugated cartons can be widely applied in automatic stacking at the end of the packing line.
