Stacking system for plates, sheets and foils using vacuum - has underpressure permanently connected to conveyor and separated automatically from plate when plate moves over predetermined position.

摘要

The underpressure can be connected by the leading plate edge in the transport direction as this plate edge passes a suction slit between the conveyor and plate. As the trailing plate edge passes by this suction slit the underpressure is lifted so that the plate falls through gravity from the conveyor onto the stack. The conveyor belt (10) has longitudinal grooves through which the vacuum source (13,15) is connected to the plate (B'). The belt can be an endless conveyor belt guided over two pulleys (11,12). USE/ADVANTAGE - Accurate stacking of plates and sheets with aligned edges.
