Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paper sheet storage device, and more particularly to a paper sheet storage device suitable for accumulating and storing various types of paper sheets having different sizes.

[0002]

2. Description of the Related Art Conventionally, an apparatus for accumulating paper sheets such as banknotes has a sheet feeding end held by a conveyance belt, such as an apparatus disclosed in Japanese Patent Publication No. 63-23103. The impeller provided between the plurality of rollers is pushed into the storage portion to be accumulated. The blades of the impeller press against an inclined guide provided above the holding plate that holds the conveyed paper sheets, and further push out in the guide inclination direction and press the rear end of the paper sheets in the stacking direction to deposit.

[0003]

In the above-mentioned prior art, the impeller is provided between a plurality of rollers at the conveying end, and the paper sheets pinched and conveyed by the conveying belt are pushed out by the blades of the impeller. By pushing the trailing edge of the paper sheets in the stacking direction, the paper sheets are forcibly moved in the transport direction and the stacking direction to achieve orderly stacking.

However, as shown in FIGS. 2 and 3, when a wide variety of paper sheets having different sizes are handled, the installation position of the impeller becomes a problem. As shown in FIG. 2, when the impellers 30 to 34 are attached according to small-sized paper sheets,
For large-sized paper sheets 20, since the distance from the outermost impellers 30 and 34 to the side edges 20a and 20b of the paper sheets is large, the impellers 30 to 34 are pushed in the stacking direction. The pushing force of the blades of the impellers 30 to 34 is not transmitted to the side edges 20a and 20b of the paper sheets, so that they are not pushed in the stacking direction. Therefore, when the paper sheets are continuously fed, a jam occurs due to contact with the leading edge of the succeeding paper sheet. Further, as shown in FIG. 3, when the impellers 30 to 34 are attached according to a large-sized paper sheet, a paper sheet 21 that has been conveyed with a slightly smaller size or with a slight deviation from the impeller is conveyed. In some cases, only a small amount of impellers 30, 34 hit the side edges 21a, 21b of the class, and the portions where the impellers 31, 32, 33 are sufficiently pushed in in the stacking direction, but only a small amount of impellers 30, 34 hit. The side edges 21a, 21b of the missing paper sheets may not be pushed in the stacking direction. At this time, as shown in FIG. 4 and FIG.
At 1, the paper sheet 21 is greatly deformed and enters the inside of the impeller 30. FIG. 4 shows such a state, and FIG. 5 shows FIG.
The figure which looked at the impeller 30 vicinity from the front is shown. When the paper sheet 21 is largely deformed in this way, the side edge 21a of the paper sheet 21 is deformed.
Since it goes out of the orbit of the blade tip of the impeller 30, it cannot be pushed in the stacking direction by the impeller 30, and when the paper sheets are continuously fed, they come in contact with the following paper sheet tips, It causes a jam.

An object of the present invention is to provide a paper sheet storage device that prevents jamming of paper sheets and stores them efficiently.

[0006]

The above object is to bring the leading end of the paper fed in from the carrying means in the carrying direction into contact with a locking member, and to put the trailing end of the paper near the leading end of the carrying means. , The blades having a rotation center at a position lower than the conveyed paper sheets are combined with blades having different lengths and arranged radially.

[0007]

According to the present invention, by combining blades of different lengths with the impeller and arranging them in a radial pattern, even a paper sheet that has been greatly deformed by the passage of a long blade will be less deformed by the short blade that passes next. When the long blade passes again, the rear end of the paper sheet, which has been reduced in deformation, can be easily pushed in the stacking direction, jams can be prevented, and storage can be performed efficiently.

[0008]

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows a paper sheet storage device according to an embodiment of the present invention. The paper sheet storage device has a storage portion 1 for storing paper sheets 22. The storage unit 1 includes a locking member 2 having a guide surface for locking the paper sheets 22 sent from the preceding stage and orthogonal to the transport direction, and a side wall 4 forming a storage unit together with the locking member 2.
The rear wall 3 and the holding plate 7 for holding the accumulated paper sheets 22. The locking member 2 is moved in advance according to the size of the paper sheet sent by the conveying means, and forms an appropriate storage portion for the paper sheet. At the entrance end of the storage unit 1, the impellers 5a, 5b
Is provided. Further, a conveyor belt 6 for holding and feeding the paper sheets passes through the upper part of the storage unit 1, and the conveyor belt 6 is driven by a roller 8. The two types of impellers 5a and 5b push the paper sheets conveyed by the conveyor belt 6 into the storage unit 1 and deposit them. In the embodiment, three impellers 5a are provided at the center and two impellers 5b are provided at both ends.
Is provided. The impeller 5a has blades 50 of the same length.
Are arranged radially, and the impeller 5b has blades 50a and 50b of two different lengths alternately arranged radially. An example of the impeller 5b is shown in FIGS. In the impeller of FIG. 12A, long blades 50a and short blades 50b are alternately arranged. In the impeller of FIG. 12B, two short blades 50b are arranged next to the long blade 50a. The impeller of FIG. 12 (c) has long blades 50a, short blades 50b, and shorter blades 50c arranged in this order. The impeller of FIG. 12 (d) has a long blade 50a.
Next to the short blade 50b, next to it a shorter blade 50c,
A short blade 50b is arranged next to it. 12 (a)-
The alternate long and short dash line in (d) shows the trajectory of the blade tip when the impeller rotates. The example of FIG. 1 uses the impeller of FIG. 12 (a).

First, a case where a small-sized paper sheet 23 is fed by the conveying means as shown in FIG. 6 will be described. The leading end 11b of the fed leaves 23 is locked by the locking member 2, and the trailing end 12b of the paper leaves is pushed by the impeller 5a in the stacking direction. Here, the impeller 5a is two impellers 5b.
Even when the paper sheets 24 of the same size as the inner spacing dimension L of the blades are continuously fed, the paper sheets 24 can be pushed in the stacking direction so as not to interfere with the succeeding paper sheets. There is.

Next, as shown in FIG. 7, when a large-sized sheet 25 is fed by a conveying means (not shown), the leading edge 11d of the sheet is locked by the locking member 2 and the trailing edge 12d of the sheet is fed. Are pushed in the deposition direction by the impellers 5a and 5b to deposit.

Then, as shown in FIG. 8, the side edge 1 of the paper sheet is
When only a small amount of the blade 3a hits the blade of the impeller 5b, the side edge of the sheet may be greatly deformed and enter the inside of the blade 50a of the impeller 5b depending on the conveyance state of the sheet. When the paper sheet is greatly deformed in this way, the side edge 13a of the paper sheet goes out of the track of the blade tip of the impeller as shown in FIG. 9, so that it cannot be pushed in the stacking direction by the impeller. . However, as shown in FIG. 10, when the next short blade 50b arrives due to the rotation of the impeller 5b, the deformation of the side edge 13a of the paper sheet becomes small. When the deformation of the paper sheet is reduced in this way, as shown in FIG.
Since 3a enters inside the orbit of the blade tip of the impeller, the rotation of the impeller 5b causes the next long blade 50a to push the deformed paper sheet 1a in the stacking direction. Even when the paper sheets are continuously fed, they pile up orderly without interfering with the subsequent paper sheets.

In the above-mentioned embodiment, the impellers 5b at both ends are provided.
Although the lengths of the blades are different, the lengths of the blades of the three central impellers 5a may be different as in the impeller 5b.

[0013]

As described above, according to the present invention, by arranging blades having different lengths radially, it is possible to prevent a jam even when the paper sheets are continuously fed,
It can be stored efficiently.
