されている。[Means for Solving the Problems] According to the present invention, the above-mentioned problem is a sheet discharge device in a machine for processing sheets, which is used as an intermediate stack when replacing the stack. An intermediate stack forming device capable of running from the front edge side of the stack in the direction opposite to the sheet conveying direction to the range where the sheet is to be discharged for receiving, and the main stack of sheets and It is arranged at the trailing edge of the intermediate stacking sheet so as to be capable of abutting while reciprocally vibrating in the sheet conveying direction, and is rotatable with respect to the intermediate stacking sheet forming apparatus in order to smoothly run into the intermediate stacking sheet forming apparatus. A sheet-stopper, the sheet-stopper being arranged transversely to the sheet-conveying direction above the plane including the upper surface of the intermediate stack and in the sheet-conveying direction. Horizontally with respect to the sheet conveyance direction, with a predetermined interval on the strip that vibrates back and forth. Has a central section extending transversely to the sheet conveying direction, at its front edge, which is pivotably suspended in a direction and in which the intermediate stack forming device cooperates with the sheet stopper. The width of the section in the lateral direction with respect to the sheet conveying direction is smaller than the interval of the sheet stoppers, and the width from the central section of the intermediate stacking sheet forming device with respect to the sheet conveying direction. The leading edge of at least a part of the section extending to both sides in the direction converges in the opposite direction to the sheet conveying direction and is tapered, and the value of the intersection angle formed by the extension line is the intermediate stacking. It is set so that the sheet stopper is pushed and swung by the front edges when the sheet forming apparatus is completely driven and is placed on the upper surface of the intermediate stacking sheet forming apparatus. Has been resolved.

It is printed by a printing machine, not shown, and then conveyed by the sheet gripping device 4 onto the main stack 7. Then, when the gripping end of the sheet gripping device 4 is opened at a predetermined position on the main stack 7, the sheet 6 is discharged onto the main stack 7. In this case, the rear edge of the sheet 6 is
It is held by a braking device 8 (for example, a suction roller). The braking device 8 operates at a speed slower than the conveying speed of the sheet 6 and is horizontally movable between the two frame walls 9 and 11 of the sheet discharge device 1 (not shown). ) Is supported by. The horizontal beam can be moved in the horizontal direction so that it can be adapted to sheets of different sizes.

The strip 13 is rigidly connected to the carriage 12 so that it can move in this way. The carriage 12 rotatably supports two rollers 41, 42 on each side facing the frame walls 9, 11, and these rollers 41, 42 are guided by a guide 43 fixed to the frame walls 9, 11. Guided horizontally inside. In this case, each first roller 41 is in contact with a cam 46 which is eccentric to the braking device 8. A compression spring 44 is supported on one side by the frame walls 9 and 11, respectively, and on the other side by the carriage 12. As a result, the carriage 12 is oscillated by the cam 46 in a horizontal reciprocating manner against the return force of the compression spring 44.

上面と接しながら振動する。When the main stack 7 on the lower side and the intermediate stack 25 on the upper side are separated, these sheet stacks until the front edge of the intermediate stack forming device 21 abuts the sheet stoppers 18, 19. Stopper 18,
19 positions the rear edges of the main stack 7 and the intermediate stack 25. However, when the front edge of the intermediate stack forming device 21 contacts the sheet stoppers 18, 19, the upper intermediate stack 25 and the lower main stack 7 are separated. afterwards,
The lower main stack 7 no longer has to be positioned. Therefore, when the intermediate stack forming device 21 runs, it advantageously contacts the sheet stoppers 18, 19 and the sheet stoppers 18, 19 are transverse to the sheet conveying direction or in the middle. In the lateral direction with respect to the running direction of the stacking sheet forming device 21, the pins 16 and 17 are pivoted upward respectively to ride on the upper surface of the intermediate stacking sheet forming device 21. After that, the sheet stoppers 18 and 19 vibrate while coming into contact with the upper surface of the intermediate stack forming device 21.

差している。The pivoting movement of the sheet stoppers 18, 19 is brought about by the front part of the intermediate stacking device 21. For this purpose, the intermediate stack forming device 21 is arranged in two opposite directions (intermediate stack forming device 22 running direction) with respect to the sheet conveying direction with a space b (b <a) between them. It has slanted leading edges 23, 24 that converge and taper to each other, and the extension lines 26, 27 of the leading edges 23, 24 intersect at an apex 28 at an acute angle α (eg 90 °). There is.

主積み紙プレート31上に載置される。The force to move the sheet stoppers 18, 19 downwards is generated only by the gravity of the sheet stoppers 18, 19. However, this force may be reinforced by a tension spring or a compression spring. In the basic position, i.e. in the position in which the main stacking plate 31 is lowered so that it does not contact the sheet stoppers 18, 19, the sheet stoppers 18, 19 will always be at their pivot point (pin 1
Vertical lines 29,30 passing through 6,17) and small angles β (about 1
5 °) is suspended on pins 16 and 17. Therefore, when the main stacking plate 31 is, for example, emptied and rises and comes into contact with the sheet stoppers 18 and 19 having such a configuration, the sheet stoppers 18 and 19 are pushed up to start a swinging motion upward. To do. After that, the sheet stoppers 18, 19 are placed on the main stacking plate 31 only by their own weight.
