In the paper sheet stacking apparatus according to the present invention, at the time of paper sheet stacking, the side plate, which is the movable body, functions as a paper sheet sorting guide, and the center of the transferred paper sheets is shifted ( Since the position in the width direction is corrected with respect to the skewed (skew state) or the skew-conveyed sheet (skew state), the alignment of the sheets in the storage box is improved.

Further, the sheet stacking apparatus according to the present invention, when feeding out the stacked sheets, opens outward as the push plate rises to ease the pinching of the sheets and smoothly feed out the sheets. The operation is performed to make

〔Example〕

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a side view showing an overall configuration of a sheet stacking apparatus (hereinafter, also simply referred to as “apparatus”) showing one embodiment of the present invention. The apparatus shown in the present embodiment includes a storage box 3 for stacking, holding, and storing paper sheets 2 in a layered manner on a push plate 1 that moves vertically by a power source (not shown). And a side plate 4 that regulates the position in the conveying width direction, and is rotated about a shaft 12 by a driving source (not shown),
A transport path switching gate 11 and a gate 1 for passing the transported paper sheet 35 to the storage box 3 side or the next stage.
The paper sheet taken in 1 is stored in the storage box 3 by the arrow 16 in the figure.
A pair of rollers 13 and 14 for feeding paper from the direction, a guide plate 15 for guiding the fed paper sheet onto the pressing plate 1, and a feeding roller 21 for feeding the paper sheet 2 forward, The feed roller 22 includes a feed roller 22 for separating the paper sheets fed forward one by one, and a feeding means including a gate roller 23.

In the apparatus shown in this embodiment, the paper sheet 35 sent from the previous step is nipped and conveyed by the conveying belt 31 and the guide rollers 32 to 34, passes through the gate 11, the roller pair 13 and 14, and the guide 15 Is accumulated on the push plate 1 by the guide of (1).

Hereinafter, the structural features of the device shown in this embodiment will be described in more detail.

FIG. 3 is a top view of a main part of the apparatus shown in this embodiment,
FIG. 4 shows a side view of the apparatus shown in this embodiment as viewed from the paper sheet entrance side. As is clear from both figures, a pair of side plates 4 for regulating the position in the conveying width direction, which is a feature of the apparatus shown in this embodiment, is configured to be rotatable about a fulcrum 51 at the lower part thereof, and The overall shape is such that the upper part is inclined inward and a part thereof (the part on the paper sheet entrance side) is opened outward. The pair of side plates 4 (4a and 4b) are urged inward as described later by a spring 52 fixed to the side wall, and also by a stopper 53 also locked to the side wall. , The inclination of which is kept within a predetermined angle.

Hereinafter, the operation of the apparatus according to the present embodiment configured as described above will be described with reference to FIG. 2 in addition to FIGS. 1, 3, and 4.

First, at the time of the sheet stacking operation, as shown in FIG. 2A, the side plates 4a and 4b are inclined inward at a predetermined angle α and fixed by pressure by the spring 52 described above. . Here, the interval A between the side plates 4a and 4b in the portion where the paper sheet 35 enters is smaller than the dimension (A ₀ ) between the fixed side walls of the storage box 3.

Among the conveyed paper sheets 35, the paper sheet 35a shown in FIG. 2 (a) is used for a paper sheet 35a whose transport center position is shifted, such as a paper sheet 35a, or a paper sheet 35a which is conveyed obliquely. As a result, the position in the width direction is forcibly corrected by abutting the side plate 4a as described above, so that there is an effect that the paper falls along a locus like the paper sheets 35c and 35d. The dropped paper leaf 35d is attached to the side plate 4
As shown in FIG. 2 (b), the position in the width direction is forcibly corrected, so that it is aligned within a predetermined size in the conveyance width direction, and contacts the fixed side walls 3a and 3b of the storage box 3. As a result, the fixed side wall 3a of the storage box 3 and
The resistance force received by the sheet 3b from the sheet-side end face is reduced, and a stable sheet stacking state can be realized. This also facilitates the operation of feeding the sheet to the next stage.

Next, an operation of feeding the paper sheets 2 sparsely stacked in the storage box 3 by the above-described operation to the next process will be described.
In the paper sheet feeding operation, as shown in FIG. 2 (c), the stacked paper sheets 2 move up together with the pressing plate 1, come into contact with the feeding roller 21 and are sent forward, and are fed forward. The sheets are separated one by one by the gate roller 23 and fed out. At this time, the push plate 1 is raised in order to bring the paper sheet 2 into contact with the feeding roller 21. By this operation, the paper sheet 2 comes into contact with the side plates 4a and 4b, and the side plate 4a
And 4b are retracted against the above-mentioned spring 52, as shown at 4a 'and 4b' in FIG. 2 (c). As a result, the contact resistance between the paper sheet 2 and the side plates 4a 'and 4b' is reduced. Further, since the paper sheets 2 are in a stable accumulation state at the time of accumulation, a stable feeding operation can be realized.

According to the above-described embodiment, the side plates 4a and
As shown in FIG. 3, 4b is fixed on both sides in the width direction of the stacked paper sheets 35 with a distance A, and the paper sheet inlet side forms an inclined opening, It is shaped so that the paper 35 can be easily taken in. As a result, the fed paper sheets 35 are normally accumulated without contacting the side plates 4a and 4b. However, when the sheet 35 is conveyed (shifted state) off the center of conveyance, or conveyed skewed (skewed state), the sheet 35 is moved to the side plate 4a or
4b, while the position is regulated in the transport width direction, the position in the width direction is corrected so as to improve the alignment, as in 35b or 35c, and further, it is fed to reach a predetermined position,
It is accumulated like d.

In addition, the said Example is an example of this invention,
It goes without saying that the present invention is not limited to this. For example, how to select the bending angle of the side plates 4a and 4b or the opening angle of the paper sheet entry side, and whether to form the whole by joining flat surfaces or include a curved surface, etc., actually design the device. This is a matter that can be arbitrarily set each time the operation is performed. The same applies to the material.

〔The invention's effect〕

As described above, according to the present invention, according to the present invention, a storage box having a side wall for stacking and storing paper sheets on a push plate and a stack for guiding and stacking the paper sheets on the push plate At least the upper part of the side wall parallel to the paper industry transport direction of the storage box is a movable body having an open side in the paper sheet entering direction, and is the movable body at the time of paper sheet accumulation. Since the side wall is configured to be biased inwardly at a predetermined angle, a remarkable effect of realizing a low-cost paper sheet stacking device with a simple mechanism can be achieved.
