However, in the above-described integrated paper discharge device, when extruding the integrated signature by the pusher 7, or scratch the Rizan Ru signature by the passage of the pusher 7, in contact with the pusher 7 signatures and those Due to the frictional resistance between the remaining signatures without contact, there is a problem that the signature may be damaged by colliding with the pressing plate 11 on the moving side where the signature is dragged and pushed out as much as possible. It was.

  The problem to be solved by the present invention is that only a predetermined number of sheets such as stacked signatures can be reliably pushed out without giving frictional resistance to adjacent sheets, and the problem is solved. It is in.

The present invention includes a pusher plate that abuts against a rising side surface of each predetermined sheet to be carried up and pushes forward sequentially and is opposed to the pusher plate and pushed forward by the pusher plate. retains its standing in contact with the upright sides of the paper person, a holding plate which moves backward for each sheet to be pushed by the pusher plate, are arranged in the same direction as the moving direction of the holding plate, the holding and the pusher plate In a stacking paper discharge device comprising an extrusion rod for extruding paper accumulated between the plates in a direction perpendicular to the direction of movement of the holding plate, the holding plate is separated by a gap corresponding to the movement of the extrusion rod. thereby disposed above the push rod, to one end of said push rod, extending in the extrusion direction, to fix the partitioning rod for dividing the integrated sheet, both before Symbol dividing rod The pivoted pulley, respectively, passing over the belt to the opposite ends of the pulley, the belt, is brought into contact with standing side face of the sheet that remains is partitioned and Key characterized by being.

According to the present invention, since the holding plate is disposed above the extrusion rod with a gap corresponding to the movement of the extrusion rod , the holding plate is moved immediately after the accumulated paper discharged by the extrusion rod passes the holding plate. The sheet can be moved and brought into contact with the head of the sheets being stacked, so that even if sheets are continuously stacked, there is no risk of the sheets falling. In addition, pulleys are pivotally attached to both ends of the sorting rod that divides and stacks the accumulated paper between the paper bundle to be pushed out by the extrusion rod and the paper to be left unextruded, and the belt is passed around the pulleys at both ends. Because the belt is brought into contact with the rising side surface of the remaining paper that is separated, the belt is in close contact with the paper left by the movement of the sorting rod, and the paper that moves in the direction opposite to the moving direction with respect to the sorting rod is left. Thus, the frictional resistance due to the movement of the sorting rod is not applied, so that it is possible to prevent the remaining paper from being damaged or dragging out the paper as much as possible. Thus, there is an effect that a predetermined number of sheets can be stably ejected and discharged.

  A paper that pushes out the paper accumulated at the end of the push rod for the purpose of surely extruding and discharging only a predetermined number of papers such as the collected signatures without giving frictional resistance to the adjacent paper. This was realized by attaching a sorting rod for separating the bundle from the remaining paper and providing a belt movable on the outer periphery of the sorting rod with respect to the sorting rod.
