AN APPARATUS FOR STACKING FLAT ARTICLES ON-EDGE

摘要

An apparatus for stacking flat articles on-edge has a helical drive assembly with spaced-apart helical screws. The helical screws receive and hold the articles on-edge therebetween, and eject the articles towards a stack holding unit. The stack holding unit is configured to hold a stack of articles on-edge separately from the helical screws. The apparatus includes a conveyor that supports the lower edges of the articles during their transport to the stack holding unit. The stack holding unit has an article entry opening with a height that is smaller than a height of the articles to be stacked during operation, and the height of the article entry opening is preferably adjustable.
