The Stack magazine module separates workpieces from a magazine. Up to
8 workpieces can be stacked in any order in the magazine barrel. The workpieces
must be inserted with the open side facing upwards.
A double-acting cylinder pushes the lowest workpiece from the gravity-feed
magazine up to the mechanical stop. This position serves as a transfer point to the
next module (e.g. Changer module).
The available workpiece in the magazine barrel is detected by means of a through-
beam sensor. The position of the ejecting cylinder is sensed electrically via inductive
sensors. The advancing and retracting speed of the ejecting cylinder is infinitely
adjustable by means of one-way flow control valves.
