Apparatus for moving individual sheets from a stack of sheets

A measuring device (60) measures the value (t) of a chosen parameter (thickness) of what has been lifted by a lifting assembly (40) from a stack of sheets (1) of material and allows the lifted material to be moved from the stack when the value is in a predetermined relationship to a reference value...

Beschreibung
Zusammenfassung:	A measuring device (60) measures the value (t) of a chosen parameter (thickness) of what has been lifted by a lifting assembly (40) from a stack of sheets (1) of material and allows the lifted material to be moved from the stack when the value is in a predetermined relationship to a reference value (T). One (45a) of a plurality of selectively releasable members (45) on the lifting assembly (40) is moveable in two horizontal directions to locate a sheet attached to the one releaseable member (45a) against locating pins (5, 6) on the work table (3) of the punch press (4). The entire system may be operated automatically by a controller (90).
