Abstract

PURPOSE:To obtain a compact paper sheet handling device by feeding the paper sheets with revolutions of a roller having an impeller when the paper sheets are supplied and then transmitting the motive power so as not to revolve the roller having an impeller when the paper sheets are drawn out. CONSTITUTION:When a paper sheet 4 is supplied to a guide roller 18 and a roller 11 having an impeller through a main transfer path, the roller 11 is revolved toward an arrow (a) and the sheet 4 is held between both rollers 11 and 18. Thus the sheet 4 is transferred to a store part 1. When the sheet 4 is drawn out, the revolutions of a motor are absorbed by the blind racing of a one-way clutch and therefore the revolutions of the controller 11 are prevented. In such a constitution, the roller 11 is prevented from touching the sheet 4 when the sheet 4 is drawn out. Then it is possible to obtain a compact paper sheet handling device including a paper sheet stacking/draw-out mechanism in a simple constitution.

Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a paper sheet handling device that handles paper sheets such as banknotes. The present invention relates to a sheet handling device having a stacking/feeding mechanism that feeds paper sheets.

[Prior Art] Generally, a paper sheet handling device that handles paper sheets, such as a bank terminal device that handles banknotes, has a plurality of safes for different denominations and a main conveyance path that selectively transports required banknotes from the safes. It is comprised of a paper sheet stacking/feeding mechanism that temporarily stacks the banknotes switched from the main conveyance path by a gate and then feeds out and discharges them one by one, and a banknote discrimination mechanism.

The paper sheet stacking/feeding mechanism rotates a roller with an impeller disposed at the entrance of the paper storage section and an idler roller opposing the roller, thereby depositing the paper sheets at a predetermined position in the space above the storage section. It is configured to take in a large number of banknotes and store them therein, and to press the stacked banknotes against a take-out roller provided above and feed them out by rotation of a feed-out roller.

This type of sheet stacking/feeding mechanism generally uses a main conveyance path that rotates in one direction as the rotational drive source for the impeller-equipped roller.
The drive source for the take-out roller and the feed roller is obtained from a separate power source.

In addition, as the above-mentioned paper sheet handling device, for example,
The technique described in Japanese Patent No. 60561 is mentioned.

[Problem to be solved by the invention] In recent years, the amount of money stored in bank terminal devices has tended to increase due to the demand for operation on holidays, and as a result, there has been a growing need to downsize mechanical parts other than the safe section. The device based on this technology cannot meet the need for miniaturization of the device because the sheet stacking/feeding mechanism cannot be made small. In other words, in the conventional paper sheet stacking/feeding mechanism, if the space between the impeller-equipped roller and the stored paper sheets is made smaller, the blades of the impeller-equipped roller, which share a common drive source with the main transport path, rotate while storing the paper sheets. Continuous contact with paper sheets causes ■ shortening of the lifespan of the blades, ■ damage to stored banknotes, and ■ malfunctions such as diagonal feeding of paper sheets and uneven spacing due to this damage, making it difficult to miniaturize. .

An object of the present invention is to eliminate the problems caused by the prior art, and to provide a sheet handling device having a simple configuration and a downsized sheet stacking/feeding mechanism.

[Means for Solving the Problems] In order to achieve the above object, the present invention stores a plurality of supplied paper sheets by rotating a roller with an impeller, and extracts the paper sheets by rotating a take-out roller and a feeding roller. A sheet handling device equipped with a sheet stacking/feeding mechanism that sequentially separates and discharges sheets includes a motor that rotates in two directions, and a motor that rotates in one direction when the sheets are carried in and picks up the sheets by contacting them with blades. a roller with an impeller that rotates when taking out the paper sheets, a take-out roller that rotates in contact with the upper part of the accumulated sheets when taking out the sheets; a feed-out roller that rotates and discharges the sheets when the take-out roller takes out the sheets; When the motor rotates in one direction, power is transmitted so that the take-out roller and the feed roller are rotated in the same direction and the impeller roller is rotated in the opposite direction to bring in paper sheets, and when the motor rotates in the other direction, the power is transmitted. The first feature is that the paper sheet stacking/feeding mechanism is provided with a power transmission mechanism that transmits power so that only the take-out roller and the feeding roller are rotated in the same direction and the paper sheets are discharged. .

Furthermore, the second feature of the present invention is that the power transmission mechanism transmits power so as to rotate the impeller-equipped roller only when a paper sheet is supplied.

[Function] The first feature of the present invention is that the paper sheets are carried in by rotating the impeller roller during the sheet feeding operation, and the power is applied so as not to rotate the impeller roller during the feeding operation. By providing a paper sheet stacking/feeding mechanism that transmits paper sheets, the impeller-equipped roller is prevented from hitting the paper sheets when paper sheets are fed out, and the paper sheet handling including the paper sheet stacking/feeding mechanism is simple and compact. We can provide the equipment.

Furthermore, the second feature of the paper sheet handling device is that the paper sheet stacking/feeding mechanism is equipped with a power transmission mechanism that rotates the impeller roller only when feeding paper sheets, thereby extending the life of the impeller roller. can do.

[Embodiment] Hereinafter, an embodiment of the paper sheet handling device according to the present invention will be described in detail with reference to FIGS. 1 to 3. FIG. 1 is a diagram showing the overall configuration of a paper sheet stacking/feeding mechanism applied to the paper sheet handling device according to this embodiment, and FIGS. 2 and 3 are side views of this paper sheet stacking/feeding mechanism. It is.

First, as shown in FIG. 1, the paper sheet stacking/feeding mechanism according to this embodiment includes an impeller-equipped roller 11 that carries in paper sheets 4 supplied from the direction of arrow A by rotation of a plurality of flexible blades 10.
, a storage section 1 that accumulates and stores the plurality of supplied paper sheets 3 on a holding plate 2 that is driven up and down; a take-out roller 24 that rotates and takes out the stacked paper sheets 3 from above; It is provided with a feed roller 20 and a gate roller 23 that feed the sheet 3 taken out by the roller 24 to the next main conveyance path, and a motor 31 which is a rotational drive source for each of the rollers and is rotatable in two directions.

Although not shown in FIG. 1, the impeller-equipped roller 11 is provided with a guide roller 18 at the top as shown in FIG.
By counterclockwise rotation of the shaft 12, the paper sheet 4 is supported by the guide roller 18 and conveyed to the storage section 1, and is stored by knocking it down into the storage section 1 by the elastic force of the plurality of radially arranged blades 10. We ensure that

Further, the motor 31 transfers the rotational force of the pinion gear 32 to the gear 2.
The rotational force of the gear 28 is transmitted to the gear 28 that engages with the gear 8, thereby rotating the shaft 21 of the feeding roller 20, and the rotational force of the gear 28 is transmitted to the gear 26 via the gear 27, thereby rotating the shaft 21 of the gear 26.
5 to rotate the take-out roller 24. Further, the rotational force of the motor 31 is transmitted to the shaft 12 of the impeller-equipped roller 11 through the drive booby 22 provided at the other end of the shaft 21 of the feed-out roller 20 and the belt 15 so as to rotate the shaft 12 of the impeller-equipped roller 11 .

This transmission is indicated by the arrow a at both ends of the shaft 12 of the impeller-equipped roller 11.
Since the one-way clutches 13 and 16 that rotate only in one direction are arranged, the rotation is only in one direction. The one-way clutches 13 and 16 are attached to a housing or the like by a bracket 17.

Further, the feed roller 2 is a gate roller 2 whose rotation is prevented.
By rotating in the direction of the arrow d while in contact with the paper sheet 3, the paper sheets 3 are separated and discharged one by one. As shown in FIGS. 2 and 3, the guide roller 18 has a guide plate 5 rotatably attached to the shaft 12, and although not shown, the guide plate 5 has a comb-like shape with each tooth portion. The rollers 11, 24, and 20 are arranged so as to be inserted into the space between them.

Therefore, in this sheet stacking/feeding mechanism, when the pinion gear 32 of the motor 31 is rotated in the direction of arrow X, the feeding roller 20 is rotated in the direction of arrow C via the gear 28 and shaft 21,
The take-out roller 24 is rotated in the direction of the arrow f through the drive lever 22 or the one-way clutch 13, and the impeller roller 11 is rotated in the direction of the arrow a. motor 3
When the gear 32 of No. 1 is rotated in the direction of the arrow y, the gears 25 to 28 rotate the feeding roller 20 in the direction of the arrow d and the take-out roller 24 in the direction of the arrow g. The power transmission of 15 is carried out by one-way clutches 13 and 16, and the impeller-equipped roller 11 is configured to be prevented from rotating.

Next, the operation of the sheet stacking/feeding mechanism constructed in this way will be explained with reference to FIGS. 2 and 3.

First, the paper sheet 4 is transferred from the main conveyance path (not shown) to the guide roller 18.
When the roller 11 is supplied with the impeller, the motor 31 rotates the gear 32 in the direction of the arrow X.
By rotating the paper sheet 1 in the direction of the arrow a, the paper sheet 4 is conveyed to the storage section 1 while being held between the rollers 11 and 18. Therefore, the paper sheets 4 are accumulated on the holding plate 2 by the guide plate 5 of the guide roller 18 descending downward and by the rotation of the blade 10 in the direction of arrow a. At the same time, the take-out roller 24 and the feed roller 20 are rotating in the directions of arrows f and C, respectively, as shown in FIG. contact is prevented. The above is the sheet stacking operation in this embodiment.

Now, when the paper sheet stacking operation is completed and a paper sheet feeding operation is instructed, the paper sheet stacking/feeding mechanism in this embodiment performs the following steps.
It works as follows.

First, as shown in FIG. 3, this mechanism lifts the guide plate 5 of the guide roller 18 clockwise by a mechanism (not shown) and moves the holding plate 2 upward until the upper part of the stacked paper sheets 3 contacts the take-out roller. Move to.

In this state, the mechanism drives the motor 31 in the direction of arrow y, rotates the take-out roller 24 in the direction of arrow g, and rotates the feed roller 20 in the direction of arrow C, so that the take-out roller 24 picks up the upper stacked sheets 3. The paper sheet 3 is conveyed in the direction of the feed roller 20, and the feed roller 2o, together with the stopped gate roller 23, separates the sheet 3 and discharges it in the direction of arrow B, and discharges it to the next main conveyance path.

In this embodiment, the sheet stacking/feeding mechanism controls the rotation of the motor 3l by the one-way clutch 13 in this feeding operation.
and the impeller roller 11 is not rotated due to absorption by the idle feeding of 16, the blade 10 hits the paper sheet 4, reducing the life of the blade 1o and damaging the paper sheet 3;
It is possible to prevent malfunctions such as uneven spacing due to diagonal feeding of paper sheets due to banknote damage.

The paper sheet stacking/feeding mechanism according to this embodiment uses one-way clutches 13 and 16 to prevent rotation of the impeller roller 11 during the feeding operation of the paper sheet 3, thereby preventing damage to the paper sheet. To prevent this, the paper sheet handling device can be downsized.

Note that the impeller-equipped roller of the paper sheet stacking/feeding mechanism according to this embodiment is provided with a paper sensor on the main conveyance path near the roller, and rotates only when a paper sheet is carried in by the paper sheet sensor. You can configure it as you like.

Since this paper sheet stacking/feeding mechanism does not rotate the impeller-equipped roller when no paper sheets are being supplied, the elastic fatigue of the blades due to rotation can be reduced and the service life can be further extended.

[Effects of the Invention] As described above, the paper sheet handling device according to the present invention carries in paper sheets by rotating the impeller-equipped roller during the paper-feeding operation, and rotates the impeller-equipped roller during the feeding operation. Since a sheet stacking/feeding mechanism that transmits power without rotating is provided, a compact sheet stacking/feeding mechanism can be constructed with a simple configuration, and thus the paper sheet handling device can be downsized.

In the paper sheet handling device according to the present invention, the paper sheet stacking/feeding mechanism is provided with a power transmission mechanism that rotates the impeller roller only when feeding paper sheets, so that the life of the impeller roller can be extended. .
