Apparatus for separating the bottom sheet of a stack or sheets

摘要

An apparatus for separating the bottom sheet of a stack of sheets contained in a stationary magazine. A rotating disc supports substantially the entire bottom surface of a stack of sheets contained in a sheet stack magazine disposed above the disc, the corner of the magazine pointing oppositely to the direction of rotation of the disc. The latter has a recess (17,18) extending radially from its periphery and also another recess (20,21) extending in the direction of rotation from the first-mentioned recess and covering an angle of rotation of about 90. degree.. A suction element (19) is adapted to be moved through the recess to the corner of the stack of sheets and in synchronism with the rotating recesses grips the corner of the bottom sheet, tips it over, and transports it to a table under the disc. A clamp lever takes over the corner of the sheet, which has been tipped over from the stack of sheets, before it is released by the suction element and holds it on the table during the peeling-off operation.
