DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention belongs to the technical field of a stacker for stacking paper sheets, such as a stacker for stacking banknotes in a banknote depositing and stacking machine.
The present invention relates to a device for preventing accumulation failure.

[0002]

2. Description of the Related Art A bill depositing machine installed in a financial institution or the like is provided with a bill stacker for temporarily storing bills deposited by a user. There are several types of systems in which the banknote stacker stores banknotes, and a system in which banknotes are stacked and stored is one type. Such a stacked banknote stacker is generally
It includes a box for stacking banknotes, and a transport mechanism (for example, a transport roller) for feeding banknotes above the bottom of the box via an entrance provided in the box.

[0003] The method of stacking bills fed above the bottom of the box by the transport mechanism into the box is roughly divided into a method of naturally dropping bills to the bottom of the box,
There are two methods: a method in which the height of the bottom of the box is adjusted in accordance with the state of storing banknotes. From the viewpoint of preventing the accumulation failure of bills in the box, a method of adjusting the height of the bottom of the box is excellent. However, in many cases, a natural fall method is adopted in order to reduce costs.

[0004]

Even in the banknote stacker employing this natural falling method, various measures have been made to prevent accumulation failure. However, FIG.
As shown in FIG. 5, when a bill (cut note) S having a cut in the transport direction (the direction of the arrow in the figure) is fed out above the bottom of the box, the tip is bent downward as shown in FIG. It falls in the same posture and falls, so it often accumulates while standing at the bottom of the box. Also,
Banknotes (folded notes) folded in the direction perpendicular to the transport direction,
Similarly, bills that are curled in the transport direction (curled bills) are also likely to accumulate in a standing state, since the leading end of the bill is folded downward during feeding.

[0005] In the conventional banknote stacker adopting the natural falling method, there is no banknote stacker which can effectively prevent the accumulation failure of such cut, folded and curled bills (hereinafter collectively referred to as habitable bills). The present invention has been made in view of the above points, and is a stacker for stacking banknotes and other paper sheets, which is a stacker that adopts a natural falling method and is used for stacking such habit tickets. It is an object of the present invention to provide a product that can prevent a defect.

[0006]

According to the present invention, there is provided a paper stacker according to the present invention, in which a paper stacker of a stack type adopting the above-mentioned natural dropping method is provided at an entrance provided in a box, in front of the entrance. A member protruding above the paper sheet transport surface by the transport mechanism at the position of
When the leading end of the paper sheet abuts on the member and warps upward, the paper sheet is sent out above the bottom of the box in an upward posture, and the member is disposed at a central portion of the paper sheet.
It is characterized in that it has a concave shape at the center so as not to abut .

When the sheet is conveyed by the conveying mechanism and reaches the entrance of the box, a member protruding above the conveying surface of the sheet is provided there. By contacting the member, the leading end of the paper sheet is forced to be in an upwardly warped posture. Since the paper sheets are fed out above the bottom of the box in such an upward posture, even if it is a custom ticket, the leading end does not bend downward. Therefore, the fallen paper sheets do not accumulate while standing on the bottom of the box, so that the accumulation failure is prevented.

[0008]

Embodiments of the present invention will be described below in detail with reference to the accompanying drawings. FIG. 1 is a side sectional view showing an embodiment of a bill stacker employing the present invention. As shown in FIG. 1A, the bill is stacked on the bill stacker and transported to the bill 1 above the bottom 1b of the box 1 through an inlet 1a provided in the box 1. Rollers 2, 3 and 4 (each roller is provided in a pair at right angles to the transport direction), and the bills fed out above the bottom 1b of the box 1 By falling to 1b, banknotes are stacked on the box 1 and stored.

At the entrance 1a of the box 1, bills S by the transport rollers 2, 3 and 4 at a position just before the entrance 1a.
The jump sheet 5 protruding above the transfer surface of the box 1 is attached to the side surface of the box 1 by a jump sheet retainer 6. Therefore, the bill S is transported by the transport rollers 2 and 3
When the paper money S is transported to the entrance 1a and reaches the entrance 1a, the leading end of the bill S comes into contact with the jump sheet 5 so that the leading end of the bill S is forced to warp upward as shown in FIG.

FIG. 3 is a perspective view showing an example of the shape and structure of the jump sheet 5. As shown in FIG. Jump sheet 5
It is made by laminating two thin (eg, about 0.3 mm thick) synthetic resins, and has a concave shape at the center. The thin structure is used to make the leading end of the bill easily warp upward by bending the jump sheet 5 in the transport direction when the leading end of the bill comes into contact (see FIG. 2 also with the jump sheet). 5 shows such a bent state). Further, the reason why the concave portion is provided at the center is to prevent the central portion of the bill from abutting on the jump sheet 5 since the bill often has a cut or a fold at the central portion.

Returning to FIG. 1, on the circumferential surface of the transport roller 2,
Eight thin plate-shaped blades 7 are attached at regular intervals along the rotation direction. (In FIG. 1A, only six blades 7 are illustrated, and illustration of the two blades 7 located in the gap between the transport roller 2 and the transport roller 3 is omitted. When the blade 7 reaches the gap between the roller 2 and the transport roller 3 in accordance with the above, the blade 7 bends in the direction opposite to the rotation direction of the roller 2 as shown in FIG. These blades 7 hit the rear end of the bill fed above the bottom 1b of the box 1 to drop the bill, thereby causing the bill and the entrance 1a of the box 1 to fall.
Plays a role in preventing stacking failure due to collision with the next banknote that has reached.

At the side of the box 1, at the position in the feeding direction of the bill by the transport rollers 2, 3 and 4, a leading end presser 8 for preventing the bill from bending and reversing, and preventing the leading end of the bill from slipping. In order to achieve this, a sheet 9 having a high surface friction coefficient is attached.

Although not shown in FIG. 1, a sheet metal guide 10 and a guide roller 11 are provided between the pair of transport rollers 2 and 3 as shown in FIG. Are provided alternately. By passing between the sheet metal guide 10 and the guide roller 11, the bill S
Has a wavy shape in a direction perpendicular to the transport direction, as shown in FIG. The reason why the banknote is made to have such a wavy shape is to enhance the straightness of the banknote that has entered the inside of the box 1. Sometimes it is possible to sufficiently prevent the tip from bending downward.

Next, the operation of the bill stacker will be described with reference to FIGS. When the bill S (see FIG. 4 (b)) conveyed by the conveying rollers 2, 3 and 4 and wavy by the sheet metal guide 10 and the guide roller 11 reaches the entrance 1a, the tip of the bill S jumps. By abutting on the sheet 5, the leading end of the bill S is forced to warp upward (see FIG. 2). Then, as shown in FIG. 5, the bill S is sent out above the bottom 1 b of the box 1 along the ceiling 1 c of the box 1 in such an upward posture. That is, even if the bill S is a habitual ticket, the leading end does not bend downward at the time of feeding.

When the leading end of the bill S fed above the bottom 1b of the box 1 comes into contact with the leading end holder 8, the leading end of the bill S moves to the sheet 9 along the leading end holder 8, and as shown in FIG. The leading end of the bill S is lightly hooked on the surface of the sheet 9. In this state, when the blade 7 hits the rear end of the bill S, the bill S falls to the bottom 1c while keeping the paper surface in the horizontal direction. Thereby, as shown in FIG. 7, the bills S are stored in the box 1 with the paper surface oriented in the horizontal direction. Such an operation is performed on each banknote conveyed to the conveying rollers 2, 3, and 4, so that the banknotes are piled up in the box 1 with the paper surface directed horizontally.

As described above, according to the bill stacker,
Even a custom ticket such as an expired ticket does not accumulate while standing at the bottom of the box, thereby preventing the accumulation failure of such custom tickets. In this embodiment, the top end of the banknote is warped upward at the entrance of the box by a jump sheet in which two sheets of synthetic resin are formed into a thin plate and overlapped with each other. However, the present invention is not limited to this. A member having a structure (for example, a member having a slope having an uphill slope in the transport direction) may be configured so that the front end of the bill is bent upward at the entrance of the box. In short, at the entrance of the box, a member is provided that protrudes above the bill conveying surface at a position just before the entrance, and the tip of the bill that has been conveyed to the conveying mechanism and has reached the box entrance is the member. What is necessary is that it comes into contact with and bends upward.

In this embodiment, the present invention is applied to a stacker for stacking banknotes. However, the present invention is a stacker for stacking paper sheets other than banknotes, and a stacker adopting a natural falling method. The present invention may be applied to a system of the type.

[0018]

As described above, according to the paper sheet stacker according to the present invention, a paper sheet having a cut, a paper sheet folded in a direction perpendicular to the transport direction, or a paper sheet Even a so-called curly ticket, such as a curled paper sheet, can be fed out above the bottom of the box without the tip being folded downward. Therefore, since such a custom ticket does not accumulate while standing at the bottom of the box, there is an excellent effect that accumulation failure of such custom tickets can be prevented.
