ABSTRACT:
A multilevel storage device for CD cases includes at least two conveyors, upper and lower, respectively, leading to a feeding station which receives groups of containers having relative hinged edges suitably oriented. A station loads groups of cases on the lower conveyor and a transfer unit which picks up the groups of cases from a downstream end of said lower conveyor to the upper conveyor when sensor means detect absence of groups of cases at an upstream end of the upper conveyor. Presence of groups of cases at a downstream end of the upper conveyor, before the feeding station is detected by other sensor means.
