Stapler processing apparatus for paper collating machine

A stapler processing apparatus comprising:

• a paper jogging tray into which a plurality of papers are to be loaded;
• paper jogging means for jogging the papers by forcing respective end faces of the papers to a reference wall of the paper jogging tray;
• a stapler for stapling the papers jogged by the paper jogging means;
• a pair of upper and lower rollers for nipping the papers stapled by the stapler therebetween;
• paper discharging means for discharging the stapled papers from the paper jogging tray by acting a transfer force due to the rotations of the upper and lower rollers on the papers;
• and
• control means for controlling the operations of the paper jogging means, the stapler, the upper and lower rollers and the paper discharging means in such a manner that:
• at stapling the papers by the stapler, the control means makes the upper roller in close contact with the lower roller thereby pressing the stapled papers to the paper jogging tray;
• after completing the stapling operation of the stapler, the control means makes the paper jogging means to stop a paper jogging operation thereof and the upper roller to separate from the lower roller thereby once releasing the papers from the upper and lower rollers;
• and subsequently,
• the control means makes the upper roller in close contact with the lower roller and also makes the paper discharging means start discharging the stapled papers.

A stapler processing method comprising the steps of:

• loading a plurality of papers to a paper jogging tray;
• forcing respective end faces of the papers to a reference wall of the paper jogging tray thereby jogging the papers;
• making an upper roller in close contact with a lower roller thereby pressing the jogged papers to the paper jogging tray;
• stapling the pressed papers by means of a stapler;
• after stapling the papers, stopping jogging the papers and further separating the lower roller from the lower roller thereby once releasing the papers from the upper and lower rollers;
• and subsequently,
• again making the upper roller in close contact with the lower roller and further discharging the stapled papers from the paper jogging tray.
