The Distributing station separates workpieces from the Stack magazine module. The
magazine barrel of the stack magazine holds up to 8 workpieces. The filling level of
the stack magazine is monitored by means of a through-beam sensor. A double-
acting cylinder pushes out the workpieces individually.
The Changer module grips the separated out workpiece using a suction cup. A
vacuum switch checks whether a workpiece has been picked up. The arm of the
transfer unit, which is driven by a rotary drive, conveys the workpiece to the transfer
point of the downstream station.
