SHEET PICKING MECHANISM

摘要

SHEET PICKING MECHANISM An apparatus is shown for removing a sheet from the top of a stack of sheets and transporting it laterally in the direction of a processing station. The apparatus comprises a pick means for frictionally engaging the exposed surface of the top sheet in a stack and transporting it laterally substantially in the plane of the top of the stack. An angled dam means is located adjacent the pick means for slidingly engaging the sheet edge and the sheet surface opposite the surface engaged by the pick means to lift sheets transported by said frictional engagement means out of the plane of the top of the stack. A first thickness sensor means senses the number of sheets that are transported past the dam. Brake means responsive to the first thickness sensor selectively apply a friction surface to the sheet surface opposite the surface engaged by the frictional engagement means when more than one sheet is transported past the dam.
