Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a paper sheet stacking device that automatically stacks and stores paper sheets, and is particularly suitable for storing a large number of folded banknotes. This invention relates to a paper sheet stacking device.

[Background of the invention]

As a conventional paper sheet stacking device of this type, for example, Japanese Patent Application Laid-Open No. 55-145962 or Japanese Patent Application Laid-Open No. 58-12
There is also one disclosed in Japanese Patent No. 5563. these are,
When storing paper sheets, a lifting roller is provided or the storage section is configured to be slanted in order to prevent the occurrence of jams due to folds or wrinkles at the edges of the paper sheets. However, with this structure, especially if the trailing edge of the paper sheet has strong creases or wrinkles, the trailing edge of the paper sheet may droop or be lifted up, causing the paper sheet to become loose when stored. Comrades collide and a jam occurs. Further, if the front end of the paper sheet being conveyed to the storage section is strongly folded or wrinkled, it will collide with the rear end of the stored paper sheet, and a jam will occur in the same way. This phenomenon is particularly problematic when filter paper sheets of different sizes are mixed together.

[Object of the Invention] An object of the present invention is to prevent paper sheets entering the storage section from engaging with paper sheets already accumulated in the storage section when storing paper sheets of different sizes or with folds. By expanding the space,
To provide a paper sheet stacking device capable of preventing paper sheets from colliding with each other during storage and allowing stable storage.

[Summary of the invention]

A feature of the present invention is that a flexible structure is provided between the end of one of the conveying paths of a pair of conveying means that grips and conveys paper sheets and the rear end of the sheets that have been accumulated in the storage section. It is made of a flexible member and is brought into contact with the front end of paper sheets entering the storage section, the rear end of paper sheets already accumulated in the storage section, and both ends thereof, and corrects deformation due to folds, etc. of paper sheets. This is where paper sheet correction means are installed.

[Embodiments of the invention].

An embodiment of the present invention will be described below with reference to FIGS. 1 to 9. FIG. 1 is a perspective view, and FIG. 2 is a side view. In each run, 1 and 2 are a pair of conveyance units, 3 is a pulley at the end of the conveyance unit 2, 4 is a conveyance belt that conveys paper sheets 8, 5 and 6 are retraction pulleys in conveyance unit 1, and 7 is a pulley at the end of conveyance unit 2. This is a retraction belt that retracts Class 8. 9 is the incoming paper sheet 8
The collar 10 that regulates the tip of the paper sheet 8 is a front plate that regulates the curling of the tip of the paper sheet 8 . 11 is a shaft on which the pulley 5 is provided, 12 is a shaft on which the pulley 6 is provided, this shaft 11.12
As shown in FIGS. 2 and 3, one or more paper sheet feeding rollers 13, 14 are provided, and a friction member such as rubber is provided around the feeding rollers 13, 14. Grain is distributed. 15 is a holding plate that supports the stored paper sheets 8 from below. As shown in FIG.
Spring 17 hung on 6 and slide bearing 1-8
, the slide bearing 18 is pulled upward by a constant pushing force by a guide shaft 19 for sliding up and down. 20 is a shaft on which the pulley 3 is provided. Reference numeral 21 designates one or more paper sheet straightening means provided on this shaft 20, which includes a boss 22 fixed to the shaft 20 and a flexible member such as nylon attached in the circumferential direction of this boss 22. It consists of 23 parts. FIG. 5 shows an example of this sheet straightening means 21. In this embodiment, on both sides and between the three end pulleys 3 provided on the shaft 20,
Four bosses 22 are each attached. and,
A flexible member 23, such as a nylon wire, is implanted into these bosses 22, for example.

In the above configuration, the paper sheet 8 is held between the pair of belts 4 and 7 installed in the pair of conveyance sections 1.2, and is conveyed in the direction of the arrow from the direction of A, B, or C.
, and the paper sheet feed-in roller 13.1.4, the paper sheet is fed up to the stopper 9 and stored. The paper sheets 8 are sequentially retracted from above, and the presser plate 15 is always held by the spring 17.
Since the paper sheet 8 is pulled upward by the paper sheet 8, the upper surface of the paper sheet 8 is in contact with the feeding belt 4. For this reason, the stopper 9
The paper sheet 8 is restrained from the pulley 6 to the pulley 6, and is kept on the same plane. When the paper sheets 8 have no creases, the stacked paper sheets lie on almost the same plane and there is no vertical variation, so the paper sheets 8 are rolled up above the paper sheets 8 that have already been stored. This prevents paper sheets from colliding with each other and can be stored stably. As the number of stored paper sheets 8 increases.

The slide bearing 18 provided on the holding plate 15 is the guide shaft 1
9 slides down, so paper sheets can be stably stored one after the other.

In particular, the storage function when storing folded paper sheets such as circulating banknotes will be explained with reference to FIGS. 6 and 7. As shown in FIG. 6, for example, some banknotes have an upward crease at the rear end portion 8a of the banknote 8. When a circulating banknote with such a top crease is stored, it is embedded in a boss 22 attached to the shaft 20. For example, the warping of the rear end 8a of the banknote 8 is corrected in the horizontal direction by the rotational force of the portion of the flexible member 23a, such as a nylon wire, which contacts the rear end 8a of the banknote 8. becomes possible. Since the flexible member 23a is configured to be freely bendable, it comes into contact with the rear end 8a of the banknote 8 one after another in succession as the shaft 2o rotates. As a result, the effect of pushing down the trailing edge of the bill is produced, so that the crease can be corrected. Next, as shown in FIG. 7, the front end 8b of the banknote 8 that has been conveyed along the feeding belt 7 is attached to a flexible material such as a nylon wire, which is embedded in a boss 22 attached to the shaft 2o. The elasticity of the portion of the flexible member 23b that abuts the rear end 8b of the banknote 8 in the member 23 allows it to be corrected upward. Therefore, when stacking, for example, circulating banknotes with a downward fold, it is possible to stack them stably without any collision with the rear end 8a of the stacked banknotes 8. This means that the engagement space 24 is made up of the front end of paper sheets that enter the banknote storage section and the rear end of the paper sheets that have been accumulated in the storage section.
However, this is due to the effect of the flexible member 23 implanted in the boss 22 attached to the shaft 20 being enlarged due to the above-mentioned action.

Next, as shown in FIG. 8, if there is a lower fold at the front @8b corner of the sheet 8 that has been conveyed along the feeding belt 7, this portion Flexible member 23b
Due to the elastic force of the portion, the tip of the flexible member 23b is dispersed along the lower surface of the front end 8b of the paper sheet 8, thereby correcting the lower folded portion at the corner of the front end 8b to its original shape. Also have.

FIG. 9 is a perspective view showing the sheet straightening operation described above. In this embodiment, the transport paths 1 and 2 each have 53 pels. That is, there are three sets of pulley 3 on the shaft 20, pulley 6 on the shaft 12, and pulley 5 on the shaft 11, and the conveyor belt 4 and the retracting belt 7 are hung as shown in FIG. For example, when the paper sheet accumulating device is used in an automatic teller machine or the like, there is a risk that not only the banknotes 8 may be folded, but also the banknotes 8 may be inserted in a half-folded state. Therefore, in order to stabilize the banknote conveyance, in this embodiment, the belts 4 and 7 are arranged as two belts each with three belts so as to hold the fold of a standard four-fold banknote, which has the most folds. There is. 8 in Figure 9
b indicates the front end of the paper sheet 8 conveyed by the three retracting bells 1 to 7, and is a flexible member that comes into contact with one banknote among the flexible members 23 shown in FIG. Due to the elastic force of 23b, the respective front ends 8b are corrected and deformed as shown in FIG. 9. The effect of causing this corrective deformation is exactly the same as that described above, so a description thereof will be omitted.

In the embodiment described above, the paper sheet straightening means 21 has a shaft 2.
0, and consists of a boss 22 and a flexible member 23, and shows four pieces fixed at positions sandwiching the pulley 3. However, the position and number of sheets need to be selected to achieve the optimum sheet straightening, depending on the number of pulleys 3, the width and rigidity of the sheets to be handled, the position and degree of folding, etc. It goes without saying. That is,
When the width of sheets to be handled is wide, or when the intervals between the sheet straightening means are too wide, it is generally necessary to increase the number of sheet straightening means. When the paper sheets to be handled have high rigidity and are strongly folded, the effect of straightening the paper sheets can be fully exerted by generally increasing the rigidity of the flexible member installed in the paper sheet straightening means.

Next, an embodiment regarding the structure and shape of the sheet straightening means will be described with reference to FIGS. 10 to 18. Figure 10 shows boss 22
A small diameter elastic body such as a nylon wire is implanted as one or more flexible members 23 at one or more locations in the circumferential direction. FIG. 11 shows a similar flexible member 23 in which flocks are continuously implanted in the axial direction.
FIG. 12 shows a similar flexible member 23 in which the flocks are continuously flocked in the circumferential direction, and FIG. 13 shows a similar flexible member 23 in which the flocks are flocked in a staggered manner in the circumferential direction. As mentioned above, since the flexible member 23 is an elastic body, when it comes into contact with a sheet of paper, even if the entirety or the tip portion thereof is deformed in the counter-rotation direction due to its elastic force. In this case, the flexible member 23
The flocking shown in FIG. 14 reduces the apparent rigidity of the sheet straightening means 21, reduces wear of the flexible member 22 due to long-term continuous operation of the sheet straightening means 21, and prevents deformation of the flexible member 23 over time. This is an example. That is, the flexible member 23, which is flocked in the circumferential direction of the boss 22, is inclined from the normal direction to the boss 22. With this configuration, the apparent rigidity of the flexible member 23 can be reduced, and at the same time, it is possible to reduce wear and prevent deformation over time. 15 shows a flexible member 23 in which a thin flexible elastic body such as a belt is fixed instead of a thin elastic body such as a nylon wire, and FIG. 16 shows a flexible member 23 in which a thin flexible elastic body such as a belt is fixed. Small-diameter elastic bodies such as nylon wires are implanted in the radial direction at one or more locations in the circumferential direction. Further, in FIG. 17, unlike the above-described FIG. 11, a small-diameter elastic body as the flexible member 23 is inclined in the axial direction from the normal direction to the boss 22. The various paper sheet straightening means 21 shown above are each selected to have an optimal configuration, position, and number depending on the width, rigidity, position and degree of folds, and space constraints for mounting of the paper sheets to be handled. There is a need. For example, if the correcting means shown in FIG. 11 or 16 is selected, the same effect can be expected even if the number of correcting means is reduced. Furthermore, if it is necessary to straighten paper sheets continuously rather than intermittently, the straightening means shown in FIG. 12 may be selected.

If the straightening effect on paper sheets is insufficient due to insufficient rigidity of the flexible member 23, either increase the wire diameter or increase the number of small-diameter elastic bodies as the flexible member 23. It is sufficient to select the thin flexible elastic body shown in .゛In Fig. 17, the tip of the flexible member 23 protrudes at a different position in the axial direction from the boss 22, so it is effective when shifting the position where the sheet is straightened in the axial direction, and it is effective when the sheet is fixed to the shaft 20. An example of this is shown in FIG. In Fig. 18, 8' is a narrow paper sheet, 8'' is a wide paper sheet, and 21' is the paper sheet correcting means shown in Fig. 17. Continuous with the wide paper sheet 8''. If the boss 22' is placed on the shaft 20,
This embodiment is effective when the roller 3' can be installed only in the immediate vicinity, and it is necessary to sufficiently straighten the paper sheets by bringing them into sufficient contact close to the side end surfaces of the bracket sheets 8'. It is. However, as shown in FIG. 18, if it is necessary to make sufficient contact with the side end surface of the narrow paper sheet 8' at the same time, as shown by the broken line in FIG. The sheet straightening means shown in the figure is effective. The length of the flexible member 23 shown in FIG. 11 is such that it sufficiently contacts the front end 8a or 8b, or both ends of the four sheets N8 in FIGS. 6 and 7, so that the sheet straightening effect is sufficient. Make it as long as possible.

As described above, the various paper sheet straightening means shown in Figs. , the optimal configuration, location, and number are selected for each.

Of course, the configuration and position of the paper sheet correction means in the present invention, a! The selection of the number, etc. is not limited to this embodiment, and it goes without saying that any conceivable combinations and modified configurations can be adopted based on the characteristics of the paper sheets.

Further, in the above-described embodiment, the sheet straightening means 21 is firmly fixed to the shaft 20, but it goes without saying that it does not need to be fixed to this shaft 20 and may be fixed to a separately provided shaft. . An embodiment in this case will be explained with reference to FIGS. 19 and 20. 19th
In FIGS. 20 and 20, the sheet straightening means 21 composed of a boss 22 and a flexible member 23 is fixed to a shaft 32, and this shaft 32 rotates in the direction of the arrow. The sheet straightening effect of the flexible member 23 in FIG. 19 is exactly the same as the sheet straightening effect of the flexible member 23 in FIG. 6, and the sheet straightening effect of the flexible member 23 in FIG. The sheet straightening effect is exactly the same as the sheet straightening effect of the flexible member 23 in FIG.

In any of the embodiments, since the paper sheet 8 and the flexible member 23 for straightening the paper sheet are forcibly in contact with each other, the rotation of the paper sheet straightening means 21 Although noise is generated along with this, the power of the generated noise is small and does not pose a problem because it is a contact phenomenon between elastic bodies.

Furthermore, although the present embodiments have all been described with respect to the case in which paper sheets are accumulated in the horizontal direction, it goes without saying that the same effect can be produced even if the paper sheets are stacked in other directions, for example in an upright position. .

In the embodiment described above, the paper sheets that have entered the storage section by the pair of conveying means are forcibly brought into contact with the front end thereof, or the rear end and both ends of the paper sheets that have been packed in the storage section. The sheet straightening force of the sheet straightening means allows the trailing edge of the stacked sheets to be straightened, even when handling sheets with strongly folded or wrinkled edges. A sufficient engagement space can be maintained between the front end of the paper sheet and the front end of the paper sheet that subsequently enters the storage section. This has the effect of eliminating collisions between paper sheets and stacking the paper sheets smoothly and reliably. In addition, since a flexible member is used in the contact portion of the paper sheet straightening means with the paper sheets, the power of the generated noise is small, and a highly reliable paper sheet stacking device can be provided. .

In particular, the above effect is particularly great when the paper sheets to be handled are banknotes.

〔Effect of the invention〕

As explained above, according to the present invention, it is possible to prevent paper sheets from colliding with each other during storage and to perform guided storage even when paper sheets are of different sizes or have folds or wrinkles. can.
