Stacking device to stack flat objects in standing position has helical fitting with several helixes of different diameters fixed to receiver

摘要

The stacking device has a bottom plate (6) with a support wall (5), supports (7) traveling in the stacking direction, and a helical fitting on a turning driven receiver (2). The helical fitting has several helixes (1) of different helical diameters fixed to the receiver. Tines (4) of a rake form an extension to the bottom plate. The helixes can turn between the tines.
