2. Description of the Related Art As a conventional paper discharge device of this type, FIG.
It is conceivable that the paper alignment device shown in FIG. The paper aligning apparatus 100 shown in FIG. 12 has a guide plate 102 in which the lowermost surfaces of a plurality of placed paper sheets 101 are in close contact with each other and is inclined almost vertically, and an edge surface on the lower side of the guide plate 102. It has a pair of stopper walls 103, 103 that are more upright and orthogonal to each other, and a plurality of air ejection ports 104 are provided in the paper stacking portion of the pair of stopper walls 103, 103. Then, after the air is blown onto the plurality of sheets 101 from the respective air outlets 104, the guide plate 102 and the pair of stopper walls 10 are formed.
The paper is aligned by vibrating the vibrators 3, 103 by a vibrator (not shown).

Further, as another conventional paper discharge device, a paper discharge tray is provided at the downstream side in the discharge direction of discharged paper, and a paper aligning plate or a paper for hitting the paper placed on the upper surface of the paper discharge tray is provided. Some have alignment bars. This is to align paper by hitting the paper ejected to the paper ejection tray with a paper alignment plate or a paper alignment rod.

[0004]

However, the conventional paper aligning apparatus 100 which is intended to be applied to the paper ejecting apparatus.
Then, a driving means for vibrating the air supply source and the vibrator and its driving source are necessary, and in the other conventional paper discharge device, a driving means and a driving means for causing the paper aligning plate and the paper aligning bar to perform a hitting operation. Because its drive source is needed
There is a problem that the entire device is complicated and the cost is high. Further, the conventional paper aligning apparatus 100 using the vibrator has a problem that noise is generated.

Therefore, the present invention has been made to solve the above-mentioned problems, and allows a plurality of superposed sheets to be placed in a good sheet alignment state, and has a simple structure and low cost. An object of the present invention is to provide a paper discharge device.

[0006]

According to a first aspect of the present invention, there is provided a paper table on which a lower surface side of discharged paper is slid,
The sheet mounting table has a front-back inclination angle that gradually inclines downward with respect to the sheet discharging direction toward the discharge downstream, and as the sheet mounting table moves in one direction with respect to the direction orthogonal to the sheet discharging direction. While having a left-right inclination angle that gradually inclines downward, at the bottom of the paper tray in the paper ejection direction, gradually downward in the paper ejection direction toward the lower side of the left-right inclination with respect to the direction orthogonal to the paper ejection direction. A paper front end stopper wall having a sloping front twist angle is provided so as to project, and at the bottom of the paper stacking table in a direction orthogonal to the paper discharge direction, the paper is gradually gradually inclined downward in the front-rear direction with respect to the paper discharge direction. It is characterized in that a paper-side end stopper wall that is inclined upward in the direction orthogonal to the discharge direction and has a side-face twist angle that is the same as the front-face twist angle is provided in a protruding manner.

In this paper discharge device, when the paper front end stopper wall and the paper side end stopper wall intersect with each other at right angles, and the corner portion located at the lowermost part of the paper loading table is the stopper corner portion, the paper loading table The sheet ejected to the sheet slides toward the stopper corner portion due to the sliding force of the combined inclination of the front and rear inclination angle and the left and right inclination angle of the sheet mounting table, and the corner portion of the sliding sheet coincides with the stopper corner portion. In this case, good paper alignment is achieved, but normally, either one of the front end surface and the side end surface of the sliding paper first comes into contact with the paper front end stopper wall or the paper side end stopper wall. If the front end face of the paper hits the front end stopper wall of the paper first because the front end stopper wall of the paper and the side end stopper wall of the paper are inclined due to the twist angle, the paper farthest from the stopper corner of the front end face of the paper The corner hits first,
The reaction force exerts a rotational moment in the direction of abutting the front end surface of the paper against the paper front end stopper wall, and this rotational movement aligns the paper in the front-rear direction, and during the rotational movement process, the paper is moved to the corner portion. Since the paper is in contact with the paper front end stopper wall only at one point and the sliding resistance is small, the paper slides left and right by the sliding force due to the left and right inclination of the paper loading table to contact the paper side end stopper wall.

Further, when the side end surface of the sheet hits the sheet side end stopper wall first, the corner portion of the sheet on the side closer to the stopper corner portion of the side end surface of the sheet hits first, and the reaction force causes the sheet to move. A rotational moment acts in the direction of abutting the side end surface of the sheet against the sheet side end stopper wall, and this rotational movement aligns the sheets in the left-right direction. Since it is in contact with the side end stopper wall and its sliding resistance is small, the paper slides forwards and backwards by the sliding force due to the forward and backward inclination of the paper tray to abut against the paper front end stopper wall. It will be located in the corner.

According to a second aspect of the present invention, in the sheet discharge device according to the first aspect, a stapler is provided at a stopper corner portion where the sheet front end stopper wall and the sheet side end stopper wall intersect at a right angle. Characterize.

In this paper discharge device, in addition to the operation of the first aspect of the invention, the stapler can be used to staple the paper discharged to the paper table.

Is.

As shown in FIG. 1, a collating device (collator)
1 has a plurality of paper feed trays 2a to 2j arranged in the vertical direction, and a large number of sheets 3 stacked on the respective paper feed trays 2a to 2j.

Section (paper discharge device) 6.

As shown in FIGS. 2 to 5, the paper discharge section 6 has a guide plate (paper loading table) 10 on which the lower surface side of the discharged collated product 4 slides. The guide plate 10 is inclined at a front-back inclination angle A that gradually inclines downward with respect to the discharge direction T toward the discharge downstream.
Is inclined at a left-right inclination angle B that gradually inclines downward in one direction with respect to the direction S orthogonal to the paper discharge direction T.

At the lowermost portion of the guide plate 10 in the paper discharge direction T, a front twist angle is gradually inclined downward in the paper discharge direction T as it goes to the lower side of the right and left direction with respect to the direction S orthogonal to the paper discharge direction T. Paper front end stopper wall 11 having C
Is projected. Further, at the lowermost portion of the guide plate 10 in the direction S orthogonal to the paper discharge direction T, the paper discharge direction T gradually increases toward the lower side of the front-back inclination with respect to the paper discharge direction T.
Paper side end stopper wall 1 that is inclined upward in the direction S orthogonal to and has a side-face twist angle C ′ that is the same angle as the front-end twist angle C.
2 is projected (∠C = ∠C '). Further, on the side end of the guide plate 10 on the side opposite to the paper side end stopper wall 12,
A part of the paper side end stopper wall 14 is provided.

Further, when a corner portion where the sheet front end stopper wall 11 and the sheet side end stopper wall 12 intersect in the orthogonal direction S is referred to as a stopper corner portion E, the stopper corner portion E is provided with a stapler 13. The stapler 13 is provided so that when the collation product 4 is set in the stopper corner portion E, the stapler 13 detects this and automatically staples (staple-shaped U-shaped staple).

In the sheet discharge section 6 of the collating apparatus 1 having the above-mentioned structure, for example, the uppermost sheet feed tray 2a to the lowermost sheet feed tray 2 are provided.
A large number of sheets 3 classified according to types (contents) up to j are stacked, and a case where one unit of the collation 4 is formed by stacking the sheet feed trays 2a to 2j in the upper and lower order will be described. . First, when the start mode is selected, each sheet 3 from the uppermost sheet feeding tray 2a to the lowermost sheet feeding tray 2j is sequentially conveyed from the upper sheet with a predetermined timing delay, and each conveyed sheet 3 is printed. The collation unit 4 collates them to form a collated product 4. The collated product 4 is ejected to the paper ejection unit 6 via the ejection unit 5, and the collated product 4 ejected to the paper ejection unit 6 is placed in a paper alignment state.

Next, the mechanism of paper alignment in the paper discharge section 6 of the collating device 1 will be described with reference to FIGS.

First, a case where the guide plate 10 is inclined forward and backward only in the paper discharge direction T will be described. In this case,
As shown in FIG. 6A, since the discharged collated product 4 does not have a sliding force in the direction S orthogonal to the paper discharge direction T,
As shown in FIG. 6B, only the front end surface 4a of the collation product 4 is brought into contact along the paper front end stopper wall 11, and the collation product 4 is not aligned in the left-right direction.

Next, the case where the guide plate 10 is tilted right and left only in the direction S orthogonal to the paper discharge direction will be described. In this case, as shown in FIG. 7A, the discharged collated product 4 does not have a sliding force in the sheet discharging direction T, so that as shown in FIG. Only the side end surface 4b of 4 is abutted along the paper side end stopper wall 12, and
Paper alignment in the front-back direction is not performed.

Next, the case where the guide plate 10 is inclined in both the paper discharge direction T and its orthogonal direction S will be described. In this case, the paper discharged on the guide plate 10 is
As shown in FIG. 8A, the guide plate 10 slides substantially toward the stopper corner portion due to the sliding force due to the combined inclination of the front and rear inclination angles and the left and right inclination angles. If it coincides with the stopper corner portion E, as shown in FIG. 8B, good paper alignment will be achieved, but normally, due to the roughness of the sliding paper surface and the unevenness of flatness, Either one of the front end surface 4a and the side end surface 4b of the collation product 4 will abut against the paper front end stopper wall 11 or the paper side end stopper wall 12 first.

When the collation product 4 abuts on the paper front end stopper wall 11, almost the entire front end surface 4a of the collation product 4 abuts on the paper front end stopper wall 11 and slides largely from the paper front end stopper wall 11. Since the collation product 4 receives resistance, the collation product 4 may not be tilted by the sliding force due to the lateral tilt of the guide plate 10. Therefore, as shown in FIG. 8C, the collated products 4 are aligned only in the front-back direction of the paper.

Further, the collation product 4 is the paper side end stopper wall 12
When it collides with the collated product 4, almost the entire side end surface 4b of the collated product 4 collides with the sheet side end stopper wall 12 and receives a large sliding resistance from the sheet side end stopper wall 12. A situation occurs in which the guide plate 10 is not tilted due to the sliding force due to the front-back tilt of the guide plate 10. Therefore, as shown in FIG. 8D, the collated product 4 is aligned only in the lateral direction of the paper.

Based on the above, as in the embodiment of the present invention, the guide plate 10 has the paper discharge direction T and the direction S orthogonal thereto.
A case will be described in which both the sheet front end stopper wall 11 and the sheet side end stopper wall 12 are inclined at the same angle. In this case, the guide plate 1
As shown in FIG. 9A, the sheet discharged to 0 slides toward the stopper corner portion E by the sliding force due to the combined inclination of the front-back inclination angle and the left-right inclination angle of the guide plate 10, and this slide is performed. When the corner portion f of the collated product 4 that corresponds to the stopper corner portion E is shown in FIG.
As shown in (b), good paper alignment is achieved, but due to the roughness of the sliding paper surface and the unevenness of flatness, the front end surface 4a and the side end surface 4b of the collation product 4 are usually caused.
Either one of the two will come into contact with the paper front end stopper wall 11 or the paper side end stopper wall 12 first.

When the front end surface 4a of the collation product 4 strikes the paper front end stopper wall 11 first, as shown in FIG. The paper corner portion g on the side farther than the portion E strikes first, and its reaction force causes the rotational moment M1 in the direction of abutting the front end face 4a of the collated product 4 against the paper front end stopper wall 11.
The rotary motion causes the collated product 4 to be aligned in the front-rear direction. Further, in the above-described rotational movement process, the collation product 4 is in contact with the paper front end stopper wall 11 only at one point of the paper corner portion g, and since the sliding resistance is small, the collation product 4 is inclined to the left and right of the guide plate 10. Is slid in a direction S orthogonal to the sheet discharge direction T by the sliding force of the sheet, and abuts against the sheet side end stopper wall 12, whereby the collation 4
The paper is aligned in the left-right direction. As a result, FIG.
As shown in (b), the corner portion f of the collated product 4 is located at the stopper corner portion E.

In the case where the side end surface 4b of the collation product 4 hits the paper side end stopper wall 12 first, FIG.
As shown in FIG. 5, the paper corner portion f on the side closer to the stopper corner portion E of the side end surface 4b of the collation product 4 hits first, and the reaction force causes the side end surface 4b of the collation product 4 to move toward the paper side end stopper. Rotational moment M2 in the direction of hitting the wall 12
The rotary motion causes the collated product 4 to be aligned in the left-right direction. Further, in the above-described rotational movement process, the collation product 4 is in contact with the paper side end stopper wall 12 only at one point of the paper corner portion f, and since the sliding resistance is small, the collation product 4 is in front of and behind the guide plate 10. The slidable force due to the inclination causes the paper to slide in the paper discharge direction T and strikes the paper front end stopper wall 11 to align the collated products 4 in the front-rear direction. As a result, as shown in FIG. 11B, the corner portion f of the collated product 4 is located at the stopper corner portion E.

In the above-mentioned operation process, the abutting force of the side end surface 4b of the collation product 4 when the entire side end face 4b collides with the sheet side end stopper wall 12 is very large, and the reaction force causes the collation product 4 to rotate. When rotating in the opposite direction to M2, as shown in FIG.
The paper corner portion g of the side a farther than the stopper corner portion E abuts against the front end stopper wall 11.
When the sheet corner portion g hits the front end stopper wall 11, the above-mentioned behavior is exhibited. That is, when the sheet corner portion g of the collation product 4 abuts on the front end stopper wall 11, a rotational moment M1 in the direction of abutting the front end surface 4a of the collation product 4 on the paper front end stopper wall 11 acts by the reaction force thereof. By this rotational movement, the collated product 4 is aligned in the front-rear direction.

Then, in the above-described rotational movement process, the collation product 4 has the paper front end stopper wall 11 only at one point of the paper corner portion g.
Since the sliding resistance is small, the collation product 4 slides in the direction S orthogonal to the paper discharge direction by the sliding force due to the lateral inclination of the guide plate 10 and strikes the paper side end stopper wall 12, Thus, the collated product 4 is aligned in the left-right direction. Even when such a behavior is taken, as shown in FIG. 11B, the corner portion f of the collated product 4 is located at the stopper corner portion E.

As described above, a plurality of superposed sheets 3 (sheet bundle) can be placed in a good sheet alignment state, and moreover, the inclination of the guide plate 10 and the stopper walls 11 and 12 are simply.
Can be realized by setting a predetermined inclination, and since no driving means is used unlike the conventional example, it is possible to provide a low-cost paper discharge unit 6 with a simple configuration. In addition, there is no noise generated by the vibrator.

In the above embodiment, the sheet side end stopper wall 1
Since the stapler 13 is provided at the stopper corner portion E where 2 and the paper front end stopper wall 11 intersect in the orthogonal direction, the collation product 4 discharged to the guide plate 10 can be stapled by the stapler 13 so that a good paper alignment state can be obtained. It is possible to obtain the collated product 4 which is staple-stitched with.

According to the above embodiment, the front-back inclination angle A
And left and right tilt angle B, front twist angle C and side twist angle C '
Are both fixed and cannot be varied, but they may be configured to be variably adjusted. If variably adjusted, each angle can be adjusted according to the surface roughness and flatness of the paper 3 used. By making it variable, effective paper alignment operation is possible.

Further, according to the above-described embodiment, the case where the paper discharge device of the present invention is applied to the paper discharge unit 6 of the collating device 1 is shown. However, a plurality of superposed papers are discharged and this paper is discharged. The present invention can be applied to a paper discharge device that aligns stacked sheets. further,
It is also applicable to a paper discharge device that discharges only one sheet of paper and sets the discharged paper at a predetermined position.

You can
