ABSTRACT:
A conveyor moves empty containers for single-piece goods one-by-one below an openable bottom on which successive accumulations of the goods are supported. A device for holding an empty container is raised by a control system from a lower position adjacent the conveyor to an upper position below said bottom, the control system being operable to impart to said device with a container thereon a dampened and continuous downward movement from its upper to its lower position in response to falling of a said accumulation against the container when said bottom is opened. The control system includes a valve having a first position for supplying compressed air to one side of a plunger-cylinder assembly to raise said device, a second position for supplying compressed air to the other side of said assembly to hold said device in its upper position, and a third position for venting said one side of said assembly to effect said continuous downward movement.
