DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a banknote stacking mechanism incorporated in a banknote handling machine.

[Conventional technology]

In a banknote processing device used in a financial institution, for example, a banknote depositing / dispensing device, a banknote that is inserted into a device in a deposit transaction and is discriminated as depositable by a discriminating unit is sorted according to a denomination and a damage to a stage of a banknote stacking mechanism. Accumulation is done.

FIGS. 3 and 4 are schematic side views showing a conventional banknote stacking mechanism incorporated in such a banknote handling apparatus, FIG. 3 is a slide banknote stacking mechanism, and FIG. 4 is a rotary banknote stacking mechanism. Is a banknote stacking mechanism.

The slide type banknote stacking mechanism of FIG. 3 has a plurality of guide protrusions 2 formed on the side of the stage 1 and is slidably fitted into the guide grooves 3 provided in a frame or the like (not shown). The mechanism is configured so that it can move up and down and the stage 1 is biased upward by a spring 4 having a predetermined tensile force.

In this configuration, the banknotes B fed by the transporting means A composed of an endless belt and rollers that are rotated by a drive source such as a motor (not shown) are stacked on the stage 1, and the stage 1 has an increased stacking amount of the banknotes B. Then, the spring 4 balances and descends.

On the other hand, the rotary banknote stacking mechanism shown in FIG.
One end of the stage 5 is rotatably supported by a frame or the like (not shown) via a shaft 6, and the other end of the stage 5 is biased upward by a spring 7 having a predetermined tensile force. As the bills B sent by A are accumulated on the stage 5, the stage 5 rotates downward about the shaft 6 while being balanced by the spring 7.

[Problems to be solved by the device]

However, the above-mentioned conventional banknote stacking mechanism has the following problems, respectively.

That is, in the case of the slide type banknote stacking mechanism described with reference to FIG. 3, a guide protrusion is formed on the side portion of the stage, and a guide groove for slidably fitting the protrusion is provided in a frame around the stacking mechanism. Therefore, there is a problem that the structure becomes complicated and the cost becomes high.

Further, in the case of the rotary banknote stacking unit described in FIG. 4, the angle of the stage changes depending on the stacking amount of the banknotes with respect to the banknotes fed at a constant angle by the transporting means, so that the banknotes are already on the stage. The tips of subsequent banknotes are likely to hit the banknotes that have been stacked, causing folding and misalignment, making it difficult to stably stack the banknotes on the stage, and separating the banknotes on the stage from a separating roller or There is a problem that when the paper is automatically fed out by the reverse roller, a jam or the like is generated due to the folded bill or the misaligned bill.

The present invention has been made in order to solve these problems, and an object thereof is to realize a banknote stacking unit which is capable of stable banknote stacking, has a simple structure, and is inexpensive.

[Means for solving the problem]

To achieve this object, the present invention provides a first stage member having an axis serving as a center of rotation at one end, and the other end of the first stage member positioned above the one end.
First urging means for urging the stage member with a predetermined force, a second stage member whose one end is rotatably supported by the first stage member via an axis, and the second stage member. The second stage member together with the first stage member by the second biasing means for biasing the second stage member with a predetermined force so that the other end of the second stage member is above the one end. It is configured to form a substantially V shape.

[Action]

According to the above-mentioned structure, the bills fed by the conveying means are accumulated so as to straddle the first stage member and the second stage member.

Then, as the stacking amount of banknotes increases, the angles of the first stage member and the second stage member widen in balance with the forces of the first urging unit and the second urging unit. And, the height of the uppermost banknote is kept constant.

Therefore, according to this, the banknotes can be stably stacked, and the banknote stacking mechanism having a simple structure and low cost can be realized.

〔Example〕

 Embodiments will be described below with reference to the drawings.

FIG. 1 is a perspective view showing an embodiment of a banknote stacking unit according to the present invention. In the drawing, 8 is a first stage member, which is rotatably supported by a frame (not shown) by a shaft 9 provided at one end thereof. The other end of the first stage member 8 is urged upward by a spring 10 as a first urging means having a predetermined tensile force so as to be above the one end.

Numeral 11 is a second stage member, one end of which is the first through the shaft 12.
Is rotatably attached to the side surface of the stage member 8 and one end thereof is urged downward by a spring 13 as a second urging means having a predetermined tensile force, that is, the second stage member 11 The other end of is also biased upward by a spring 13 so as to be above one end, so that the second stage member 11 forms an obtuse-angled substantially V-shape with a part of the first stage member 8. Held in.

2A and 2B are side views showing the operation of the above-described structure. FIG. 2A shows a state where the banknote accumulation amount on the stage is small, and FIG. 2B shows a state where the banknote accumulation amount on the stage is large. .

First, the bill B fed by the conveying means A composed of an endless belt and rollers that are rotated by a drive source such as a motor (not shown) has the leading end side of the first stage member 8
It is mounted on the second stage member 11 so that its rear end side is mounted on the second stage member 11.

That is, the banknotes B are accumulated so as to straddle the first stage member 8 and the second stage member 11.

In this case, when the number of accumulated banknotes B is extremely small,
The banknote B has the first stage member 8 and the second stage member 11
Although it is curved to some extent along the substantially V-shaped valley formed by, the curve disappears and becomes flat as the number of stacked banknotes B increases.

Further, when the weight of the banknotes B increases as the number of stacked banknotes B increases, the force of the springs 10 and 13 is balanced and the first
The stage member 8 and the second stage member 11 of the
It rotates about 9, 12 as a center, whereby the angle of the substantially V shape formed by the first stage member 8 and the second stage member 11 widens.

Therefore, even when the number of stacked banknotes B on the first stage member 8 and the second stage member 11 is small as shown in FIG. 2A, as shown in FIG. Even if the number of stacked banknotes B increases, the angle of the banknotes B and the height of the highest banknote B are always kept constant, and stable stacking is possible.

Although the coil-shaped springs 10 and 13 are used as the first and second urging means in the above-described embodiment, the present invention is not limited to this. The second stage member 11 may be biased so as to form a substantially V shape.

[Effect of device]

As described above, according to the present invention, the first stage member having the axis serving as the center of rotation at one end and the first stage member so that the other end of the first stage member is above the one end. The first urging means for urging with a predetermined force, the second stage member whose one end is rotatably supported by the first stage member via the shaft, and the other end of the second stage member are A second urging means for urging the second stage member with a predetermined force so as to be above the one end,
The second stage member is configured so as to form an obtuse-angled substantially V-shape together with the first stage member, and the bill fed by the conveying means straddles the first stage member and the second stage member. As the amount of banknotes is increased, the angles of the first stage member and the second stage member widen in balance with the forces of the first urging means and the second urging means. Thus, the angle of the banknote stack and the height of the banknote at the uppermost position are kept constant.

Therefore, according to this, stable stacking of banknotes is possible, and stable operation is possible even when the banknotes on the stage are automatically delivered by the separating roller or the reverse roller.

Further, since the present invention can be constituted by two stage members and a biasing means for biasing each stage member, the structure is simplified and an inexpensive bill stacking mechanism can be realized.
