ABSTRACT:
An object discharge mechanism for discharging a bottommost object from a stack of objects includes a bottom platform on which the bottommost object of the stack of objects rests. The platform has a longitudinal slot running along the object discharge direction. The upper portion of a belt, stretched between two vertically mounted pulleys, runs through the longitudinal slot parallel to the upper surface of the bottom platform. Discharge projections are mounted periodically on an outer surface of the belt. The discharge projections push objects across the bottom platform in the object discharge direction when the belt is rotated. The object discharge mechanism also includes a lifting member for lifting all objects above the bottommost object in the stack of objects. The lifting member reduces the frictional force created by the weight of the stack of objects on the bottommost object during discharge of the bottommost object.
