Abstract

Embodiments of a system and method for unloading articles from a container of items for use in an automatic stack feeder are disclosed. The automatic stack feeder may comprise a belt, a moveable lower paddle, and a moveable upper paddle, wherein the lower paddle is configured to partially extend through a belt of the automatic stack feeder. The movement of the belt, the lower paddle, and the upper paddle are coordinated such that there is no need to interrupt the operation of the automatic stack feeder to unload the container.
