Sheet feeder device for the single handling and feeding of stacked sheets

摘要

A sheet feeder device for the single handling and feeding of stacked sheets, comprising a supporting structure (12) which includes at least one set of suction grabbing elements (15, 16) capable of acting on the upper face of a sheet (13) to be grabbed and transferred, placed at the top of a stack of sheets (14), where at least one group of suction elements (16) oscillates between a grabbing position on the stack and a forward releasing position, while being placed below a supporting structure (12) on an oscillating arm (20) hinged at its top end (in 22) on the shoulders (18) of the structure (12), and where the oscillation is determined by a first recessed cam assembly (23, 24) which draws its motion from a external motorized source acting through a positive mechanical transmission (35-37). A second set of suction elements (15) may be provided and rigidly connected to the same supporting structure (12). <IMAGE>
