Boxing system using conveyor apparatus

摘要

A conveyor apparatus includes first and second groups of fins which are spaced along the conveying direction to provide spaces sufficient to hold packs therein. The fins in each group are divided into first and second sets. The first and second fin groups are mounted to first and second conveyor chain pairs, respectively, and moved through pack loading and unloading stations. Stepping motors drive the first and second chain pairs independently. A controller causes a fin set after being loaded or unloaded to be forwarded to the unloading or loading station at a speed higher than the speed at which the fin sets move through the loading station.
