Abstract
Disclosed is a sheet separation method for separating a sheet one by one from a bundle of the sheets and feeding the separated sheet to a next processing step, including: suctioning an edge part of the sheet and pulling the suctioned edge part from the bundle as if to turn over the suctioned edge part; separating the sheet from the bundle, the edge part of the sheet being suctioned and pulled; and conveying the sheet separated from the bundle in a predetermined direction. A sheet separation mechanism and a sheet feeder are also disclosed.

A sheet separation method for separating a sheet one by one from a bundle of the sheets and feeding the separated sheet to a next processing step, comprising:
- suctioning an edge part of the sheet and pulling the suctioned edge part from the bundle as if to turn over the suctioned edge part;
- separating the sheet from the bundle, the edge part of the sheet being suctioned and pulled;
- and
- conveying the sheet separated from the bundle in a predetermined direction.
A sheet separation mechanism for separating a sheet one by one from a bundle of the sheets and feeding the separated sheet to a next processing step, comprising:
- a suction/pulling unit including a suction head for suctioning an edge part of the sheet and pulling the suctioned edge part of the sheet apart from the bundle by a twist movement of the suction head;
- a separation unit for separating the sheet from the bundle, the edge part of the sheet being suctioned and pulled by the suction head;
- and
- a conveying unit for conveying the sheet separated from the bundle in a predetermined direction.
A sheet separation mechanism for separating a sheet one by one from a bundle of the sheets and feeding the separated sheet to a next processing step, comprising:
- suction/pulling means including a suction head for suctioning an edge part of the sheet and pulling the suctioned edge part of the sheet apart from the bundle by a twist movement of the suction head;
- separation means for separating the sheet from the bundle, the edge part of the sheet being suctioned and pulled by the suction head;
- and
- conveying means for conveying the sheet separated from the bundle in a predetermined direction.
A sheet feeder comprising a sheet conveying mechanism which conveys a bundle of sheets and a sheet separation mechanism which separates the sheet one by one from the bundle that is conveyed to an end part of the sheet conveying mechanism and feeds the separated sheet to a next processing step, wherein the sheet separation mechanism comprises:
- a suction/pulling unit including a suction head for suctioning an edge part of the sheet and pulling the suctioned edge part of the sheet apart from the bundle by a twist movement of the suction head;
- a separation unit for separating the sheet from the bundle, the edge part of the sheet being suctioned and pulled by the suction head;
- and
- a conveying unit for conveying the sheet separated from the bundle in a predetermined direction.
