Abstract
Device for separating and feeding sheets in seriatim from a stack to a processing station. The device includes a pin which periodically contacts and forms a pivot point on the stack. A rotary wave generator is disposed to rotate about the pivot point. The rotary wave generator periodically contacts a topmost sheet in the stack and shingles (that is separates) the sheet from the stack. The shingled sheet is fed into a paper sheet aligner and into the processing station.
Claims9
A sheet shingling device for shingling sheets in seriatim from a stack onto a processing station of a utilization apparatus, comprising:
- means operable to support a stack of sheets;
- a rotary shingler member including free-rolling means disposed to contact the stack periodically, and to rotate in a plane substantially parallel to the plane of the top sheet in the stack;
- force application means, comprising a pin and a coil spring connected to said pin, carried by said shingler member and disposed at the center point of a circular orbit generated by said free-rolling means, said pin being spring biased to contact the stack prior to contact by said free rolling means, to thereby impart a restraining force to said sheets prior to a shingling force being imparted to said sheets, so that sheets are shingled at a constant angle from said stack;
- sheet feed means disposed relative to the stack, said sheet feed means being operable to receive the shingled sheets, and to reorientate the sheets to conform to a predetermined paper path;
- and
- sheet aligner means disposed within the paper path, said sheet aligner means being operable to align a sheet traversing said path.
