The present invention relates to a paper discharge storage apparatus capable of managing a predetermined number of sheets every predetermined number of sheets. The paper processing apparatus in the present invention means any type of apparatus that performs a predetermined process on a slab-like object to be processed such as printing paper and discharges it. Specifically, any printing apparatus including a stencil printing apparatus, In addition to an image forming apparatus such as an electronic copying apparatus, a post-processing apparatus that post-processes printed paper so that a printed image does not collapse is included.
[0002]
[Prior art]
Conventionally, a technique described in Japanese Utility Model Laid-Open No. 64-45654 is known as a technique for managing a predetermined number of sheets that have been subjected to image formation processing and discharged from an image forming unit. In this method, a sorting tape is cut into an appropriate length and inserted between printed printing sheets stacked every predetermined number of printed sheets. Further, as in the invention described in Japanese Patent Application Laid-Open No. 61-267659, a bundle of printing papers to be distinguished by rotating the paper ejection table by a predetermined angle for every predetermined number of printed sheets with respect to the discharging direction of the printed printing paper. Some of them overlap each other on the paper discharge table in different directions.
[0003]
[Problems to be solved by the invention]
However, the conventional apparatus has a complicated configuration and a high manufacturing cost. Further, since the sorted printed materials are stacked on a single paper discharge tray, handling of the sorted printed materials is complicated especially when many types of printed materials with a small number of sorted sheets are printed.
[0004]
For printing papers such as postcards and coated paper that do not easily penetrate the printing ink, pressure is applied to the printed surface of the printed material due to the gripping force when the printed material is removed from the paper discharge tray, and this causes the printing ink that has not dried out. There is a problem that a phenomenon called so-called “back-off” occurs, for example, the back side of the printing paper overlapped thereon.

The paper discharge receiving tray 1 includes a stacking base 2, an abutting plate 3, and a pair of side walls 4 (one on the front side is not shown in FIG. 1). The printed printing paper is discharged from the printing machine in a substantially horizontal direction as indicated by an arrow A in each figure. The direction of arrow A in which the printing paper is discharged is called the printing paper discharge direction. The abutting plate 3 has a surface orthogonal to the printing paper discharge direction. The abutting plate 3 can move along the vertical guide rail 5 parallel to the printing paper discharge direction, and the position can be adjusted. The printed printing paper discharged from the printing machine collides with the abutting plate 3, falls onto the loading table 2, and is stacked on the loading table 2. The pair of side walls 4 and 4 have vertical guide surfaces that are substantially parallel to the paper discharge direction, and are held parallel to each other. The pair of side walls 4, 4 can move along the horizontal guide rails 6, 6 parallel to the direction substantially orthogonal to the printing paper discharge direction, and the interval can be arbitrarily set by adjusting the position. A pair of side edges parallel to the discharge direction of the printing paper discharged from the printing press is regulated by the pair of side walls 4 and 4.
[0010]
If the paper discharge tray 1 of the printing press accepts and places a normal size printing paper, the paper discharge storage device of this example described below is suitable for printing smaller postcards such as postcards. It is used as a paper discharge storage device, and is used by being detachably mounted on the paper discharge receiving tray 1 as shown in FIG. As shown in FIG. 4, the paper discharge storage device of the present example includes a base body 7 that can be attached to and detached from the paper discharge receiving tray 1 and a paper discharge tray 15 that can be attached to and detached from the base body 7.
[0011]
FIG. 2 is a perspective view showing a state in which the base body 7 constituting a part of the paper discharge storage device of this example is attached to the paper discharge receiving tray 1. FIG. 4 is a cross-sectional view of the paper discharge storage device attached to the paper discharge receiving tray 1 taken along a plane parallel to the print paper discharge direction. FIG. 5 is a plan view of the paper discharge storage device attached to the paper discharge receiving tray 1. As shown in FIGS. 2 to 4, the base body 7 is a substantially horizontal plate-like member that is substantially T-shaped in plan view. The base body 7 includes a first locking portion 8 and a second locking portion 9 that detachably support the base body 7 on the paper receiving tray 1. The first locking portion 8 and the second locking portion 9 are plate-like members that are attached to the lower surface of the base body 7 and protrude downward. The first locking portion 8 is formed on the side of the base body 7 close to the printing machine, and engages with the edge of the paper discharge receiving tray 1 on the printing machine side. The first locking portion 8 fixes the position of the base body 7 with respect to the printing paper discharge direction. The second locking portion 9 has a pair of pieces parallel to the printing paper discharge direction, and can slide in the groove H between the vertical guide rail 5 and the loading platform 2 as shown in FIGS. Inserted into. The second locking portion 9 fixes the position of the base body 7 in the direction orthogonal to the printing paper discharge direction. As shown in FIGS. 4 and 5, the base body 7 has leg portions 27. The leg portion 27 is a member for supporting the base body 7 on the stacking base 2 of the paper discharge receiving tray 1 and is formed integrally with the second locking portion 9 and fixed to the back surface of the base body 7.
[0012]
A third locking portion 10 and a fourth locking portion 11 are formed on the base body 7. The third latching portion 10 and the fourth latching portion 11 are piece-like portions that are notched on a part of the base 7 and tilted toward the printing press main body. The 3rd latching | locking part 10 and the 4th latching | locking part 11 are located in a line along the printing paper discharge | emission direction. The third locking portion 10 and the fourth locking portion 11 are locked to a part of the paper discharge tray 15 when a paper discharge tray 15 described later is mounted on the base 7.
[0013]
The base body 7 is provided with a pair of paper side edge position restricting portions 12 and 12. The paper side edge position restricting unit 12 includes a substantially vertical guide surface that is parallel to the print paper discharge direction and orthogonal to the base body 7. The guide surfaces of the pair of paper side edge position restricting portions 12 and 12 are parallel to each other. The base body 7 is formed with a pair of long holes 14 and 14 whose longitudinal direction is a direction orthogonal to the printing paper discharge direction. The base portions of the pair of paper side edge position restricting portions 12 and 12 are movably attached to the base body 7 by screws 13 and 13 inserted through the long holes 14 and 14. Accordingly, the pair of paper side edge position restricting portions 12 and 12 can change the position in the horizontal direction perpendicular to the print paper discharge direction, and the interval is set to the size of the print paper to be printed as shown in FIG. In addition, it is possible to arbitrarily adjust between the maximum width position (indicated by the symbol L) and the minimum width position (indicated by the symbol S). As described above, if the paper discharge storage device of this example is used as an attachment exclusively for a postcard, when printing a reciprocating postcard, the paper side edge position restricting portions 12 and 12 are set to the maximum width position, and the normal postcard is set. When printing is printed, the dimensions are determined so that the paper side edge position restricting portions 12, 12 may be set to the minimum width position. The pair of paper side edge position restricting portions 12 and 12 restricts a pair of side edges of the printing paper discharged from the printing press parallel to the printing paper discharge direction.
[0014]
FIG. 3 is a perspective view of the paper discharge tray 15 that is detachably attached to the base 7. The paper discharge tray 15 is discharged with a paper abutting portion 17 on which the printing paper discharged from the printing machine collides, and a rear wall portion 18 for receiving the rear end of the printing paper that has collided with the paper abutting portion 17 and bounced back. And a paper stacking unit 16 on which printed printing paper is placed. At the upper end portion of the sheet abutting portion 17, a grip portion 19 is formed that is gripped by an operator to move the paper discharge tray 15. As shown in FIG. 4, a plurality of paper discharge trays 15 are stacked and used. When a plurality of paper discharge trays 15 are stacked in this way, the paper discharge trays 13 are kept at a predetermined distance so that the fingertips are put on the grips 19 of the uppermost paper discharge tray 15. Tongues 20 are formed at the four corners of the paper stacking portion 16 of the tray 15. A first opening 21 and a second opening 22 are formed in the paper stacking portion 16 of the paper discharge tray 15. The first opening 21 and the second opening 22 are locked to the third locking portion 10 and the fourth locking portion 11 of the base 7 to support the paper discharge tray 15 on the base 7. The paper abutting portion 17 of the paper discharge tray 15 is formed with an air vent opening 23 when the printing paper falls toward the paper stacking portion 16. In the rear wall portion 18 and the paper stacking portion 16 of the paper discharge tray 15, openings 24 and 25 for inserting fingertips when taking out the paper from the paper stacking portion 16 are formed, respectively.
[0015]
As shown in FIGS. 3 and 4, a plate 26 made of metal, synthetic resin, rubber, or the like is attached to the outer surface of the paper abutting portion 17 to reduce the sound generated when the printing paper collides.
[0016]
Next, a method of using the paper discharge storage device of this example will be described. A substrate 7 is attached to the paper discharge tray 1 of the printing press. A paper discharge tray 15 is attached to the base body 7. First, one side of the first opening 21 of the paper discharge tray 15 is hooked on the third locking portion 10 of the base body 7 with the gripping portion 19 side of the paper discharge tray 15 raised. Thereafter, the grip portion 19 side of the discharge tray 15 is lowered to engage the second opening 22 with the fourth locking portion 11. When taking out the paper discharge tray 15 from the substrate 7, the procedure is the reverse of the above.
[0017]
A required number of paper discharge trays 15 are stacked on the paper discharge tray 15 mounted on the substrate 7 as shown in FIG. Printing is performed in this state. The printed printing paper discharged from the printing machine collides with the paper abutting portion 17 of the paper discharge tray 15 and falls onto the paper stacking portion 16. When the recoil colliding with the paper abutting portion 17 is strong and the printing paper rebounds to the printing press, the rear wall portion 18 receives the printing paper. When the printing paper falls onto the paper stacking unit 16, air is released from the opening 23, so that the printing paper can be quickly stacked on the printing paper stacked on the paper stacking unit 16 through the paper stacking unit 16. .
[0018]
When printing of a predetermined number of sheets to be sorted is completed, the operation of the printing press is stopped. The uppermost discharge tray 15 is removed from the substrate 7 of the discharge storage device. At this time, since it is possible to hold the paper discharge tray 15 by placing a finger on the grip portion 19, there is no need to touch the printing paper placed on the paper discharge tray 15. Accordingly, there is no problem such as causing print-off by pressing the printing ink of a printing paper that has just been printed but not dried against the back side of the upper printing paper, or disturbing the printed image. The paper discharge tray 15 taken out from the substrate is placed in an appropriate place as it is, and the printing paper is dried. After drying, a finger is put through the openings 24 and 25 and the printing paper is taken out from the paper discharge tray 15.
[0019]
After taking out the paper discharge tray 15 from the substrate 7, the printing of the next lot is started, and a predetermined number of print sheets to be sorted next are received in the next paper discharge tray 15. Thereafter, similarly, taking out and drying of the paper discharge tray 15 and printing of the next lot are continued.
[0020]
A second embodiment of the present invention will be described with reference to FIG. In this example, the discharge tray 1a of the printing press includes a butting plate 3a and a side wall 4a. The paper discharge tray 15a of this example as a paper discharge storage device of the present invention integrally forms a paper stacking portion 16a, a paper abutting portion 17a, and a rear wall portion 18a, and is attached to and detached from the paper discharge receiving tray 1a. It is possible. In the case of this example, the positions of both side edges of the printing paper are regulated by the side walls 4a and 4a of the paper discharge receiving tray 1a. The interval between the side walls 4a and 4a of the sheet receiving tray 1a may be arbitrarily set.
[0021]
A third embodiment of the present invention will be described with reference to FIG. In this example, the paper discharge receiving tray 1b of the printing machine has at least a printing paper stacking base 2b. The paper discharge tray 15b of this example as a paper discharge storage device of the present invention integrally forms a paper stacking portion 16b, a paper abutting portion 17b, paper side edge position restricting portions 12b and 12b, and a rear wall portion 18b. The sheet receiving tray 1b is detachable. In the case of this example, the positions of both side edges of the printing paper are regulated by the paper side edge position regulating portions 12b and 12b of the paper discharge tray 15b. The sheet side edge position restricting portions 12b and 12b may be capable of arbitrarily adjusting the interval or may be fixed at a predetermined interval.
[0022]
【The invention's effect】
According to the paper discharge storage device of the present invention, the following effects can be obtained.
(1) Printed products can be taken out for moving or drying while being stacked on separate paper discharge trays for each sorting unit, and can be easily processed and managed for each sorting unit.
(2) Since the printed matter can be taken out from the paper receiving tray of the printing machine without touching the printed matter, even a small printed matter such as a postcard can be easily taken out while being neatly stacked on the paper discharging tray.
{Circle around (3)} Since there is no need to grip the printed material when the printed material is taken out from the paper discharge tray, there is no problem in printing such as set-off on the printed material.
