Abstract
A method and a device for automatically arranging individual paper sheets in a set of papers with the edges of said paper sheets in alignment with each other in combination with stapling said set of papers. A set of papers having unaligned edges is positioned on a lower edge of a vibrating table and the papers are joggled so that one edge of the paper sheets in the set of papers become aligned. The set of papers is thereafter urged against a lateral edge of the table while being vibrated, whereby all edges of the paper sheets become evenly aligned. In this final phase a stapler staples the set of papers together.
Claims4
A device for automatically arranging individual paper sheets in a set of papers with the edges of said paper sheets in alignment with each other in combination with stapling said set of papers, said device comprising:
- (a) a paper-receiving table, said table having a lower engagement edge and a lateral engagement edge;
- (b) means for vibrating said table;
- (c) a belt member;
- (d) a motor, said motor being adapted to drive said belt member for conveying it over said table parallel to said lower engagement edge and at right angles to a lateral engagement edge;
- (e) a pusher member affixed to said belt member, said pusher member comprising a portion of a first dog member adapted to urge the set of papers against the lateral engagement edge of said table when said belt member is driven by said motor;
- (f) a stapler, located to receive and staple said set of papers after their edges have been aligned in the final phase of operation of said pusher member;
- (g) switch means disposed in said lateral engagement edge for sensing the engagement of said set of papers with said engagement edge and causing said motor to reverse direction;
- and
- (h) an engagement member, said engagement member comprising a portion of a second dog member adapted to convey the stapled set of papers away from the table for discharging the same when said motor is reversed.
A method of automatically arranging and stapling paper sheets into a set of papers with the edges of said paper sheets in alignment with each other comprising the steps of:
- (a) conveying a set of papers in a first direction onto a vibrating table into contact with a first engaging edge such that the edges of said set of papers become aligned along said first edge;
- (b) conveying said set of papers in a second direction perpendicular to said first direction so that said set of papers are conveyed toward a second engaging edge by a pusher member whereby all edges of said set of paper become evenly aligned;
- (c) sensing the engagement of said set of papers with said second engaging edge;
- (d) stapling said set of papers;
- and
- (e) discharging said set of papers from said table by pushing said stapled set of papers in a direction opposite said second direction.
