[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for handling paper sheets such as banknotes, and more particularly to a stacking mechanism for storing sequentially supplied paper sheets, and feeding out the sheets one by one as needed. The present invention relates to a sheet handling apparatus provided with a feeding mechanism.

[0002]

2. Description of the Related Art A conventional paper sheet handling apparatus, for example, a bank terminal apparatus for handling banknotes is disclosed in Japanese Patent Laid-Open Publication No. Hei 3-2167.
As described in JP-A-88, a plurality of safes of each denomination, a main transport path for selectively transporting bills required from each safe, and banknotes switched from the main transport path by a gate are deposited and stored. A stacking mechanism, a feeding mechanism for feeding and discharging the stacked banknotes one by one as necessary, a bill discriminating mechanism, and the like are provided.The stacking mechanism and the feeding mechanism for the paper sheets are provided at a paper compartment entrance. By rotating and driving the arranged roller with the impeller and the driving roller opposed to the roller with the impeller, the paper sheets were taken into a predetermined position in the space above the storage unit, and a large number of sheets were stored and stored. The banknotes are configured to be brought into contact with a take-out roller provided at an upper portion thereof by pressing, and to be taken out by the rotation of a pay-out roller.

The construction and operation of a paper sheet stacking mechanism and a paper feeding mechanism according to a conventional example will be described with reference to FIGS. 10 and 11 are side views of the stacking mechanism and the feeding mechanism. As shown in FIGS. 10 and 11, the stacking mechanism includes a main transport path 1 for transporting the paper sheets 4 supplied in the direction of arrow A, a gate 2 for branching the paper sheets 4 from the main transport path 1, Conveyance path 1 for guiding branched paper sheets 4
50, a roller 11 with an impeller having a plurality of flexible blades 10, and a storage unit 100 for storing and stacking the paper sheets 4 on a holding plate 200 driven up and down by a drive source (not shown). , The feeding mechanism is for the stacked paper sheets 3.
A take-out roller 24 for taking out from above by rotation,
The feeding roller 20 and the gate roller 23 for feeding the paper sheet 3 taken out by the take-out roller 24 to the main transport path, and a motor (not shown) rotatable in two directions, which is a rotation driving source of each roller, are provided. ing. A pressure contact roller 110 is arranged coaxially with the impeller-equipped roller 11 and is in pressure contact with the upper drive roller 18. By rotating the driving roller 18 in the clockwise direction, the paper sheet 4 is sandwiched between the pressing rollers 110 and carried into the storage unit 100, and is beaten down into the storage unit 100 by the elastic force of the plurality of blades 10 arranged radially. The storage is assured.

[0004] Next, the operation of the deposition mechanism and the feeding mechanism configured as described above will be described. First, the paper sheet 4 branched from the main conveyance path 1 by the gate 2 is guided to the conveyance path 150, and the roller 11 with the impeller is rotated counterclockwise by the rotation of a motor (not shown).
While being held between the driving roller 18 and the pressure contact roller 110, is carried into the storage section 100. For this reason, the paper sheet 4 is guided by a guide plate 5 whose one end is supported by the shaft of the drive roller 18.
And is accumulated on the holding plate 200. At the same time, the take-out roller 24 and the feed-out roller 20 rotate counterclockwise in synchronization with each other, but since the holding plate 200 of the storage unit 100 is lowered,
Is prevented from coming into contact with. When the storing operation of the paper sheets is completed and the discharging operation of the paper sheets is instructed, the stacking mechanism and the feeding mechanism operate as follows.

First, as shown in FIG. 11, the guide plate 5 is lifted clockwise by a mechanism (not shown), and the holding plate 200 is moved upward to a position where the upper portion of the stacked paper sheets 3 contacts the take-out roller 24. In this state, a motor (not shown) is driven to rotate each of the take-out roller 24 and the pay-out roller 20 clockwise in synchronization with each other.
Is conveyed in the direction of the feed roller 20, and the feed roller 20 together with the stopped gate roller 23 feeds the sheet 3.
Are separated one by one and transported to the main transport path 1. Since the gate 2 is held at the position indicated by the solid line, the sheets 3 separated one by one are transported to the next main transport path 1 via the main transport path 1.

In the conventional paper sheet stacking and feeding mechanism, the driving roller 18 is taken out of the roller 2
FIG. 12 is an explanatory view showing a case where the dimensions are reduced by reducing the dimensions of L ₁ and L ₂ by inclining in the direction of 4 (L ₁ > L ₃ , L ₂ >).
L ₄ ). In this case, the following problem occurs. That is, the posture of the paper sheet 4 to be carried in is unstable and the paper sheet 4 is easily carried in a downward direction (the angle θ formed with the guide plate 5 is so large that the paper sheet 4 cannot follow the guide plate 5). However, there is a problem that the danger increases, that is, the performance decreases during the storing operation. This state is shown in FIG.

[0007]

In a conventional paper sheet handling apparatus, for example, a bank terminal apparatus, the amount of storage tends to increase due to a demand for a holiday operation, and therefore, mechanical parts other than the safe section are reduced in size. However, in the conventional structure, the posture of the paper sheets to be carried in is unstable and the paper sheets are easily carried downward, and the danger of interference with the stored paper sheets increases, and the storage operation is increased. There is a problem that it is difficult to reduce the size because the performance is deteriorated at the time.

An object of the present invention is to provide a paper sheet handling apparatus having a high-performance stacking mechanism and a feeding mechanism which have a simple structure and are miniaturized.

[0009]

In order to achieve the above object, a sheet handling apparatus according to the present invention guides fed sheets to a conveying path branched from a main conveying path by a gate. A stacking mechanism for storing the guided sheets in the storage section along the guide plate by rotating the drive roller and the pressure roller that presses the drive roller and the roller with the impeller provided coaxially with the pressure roller, and stored in the storage section And a delivery mechanism that sequentially separates and ejects the plurality of sheets obtained by the rotation of the take-out roller and the delivery roller, the plurality of blades of the impeller-equipped roller are formed of elastic blades, and driven. A guide roller is provided near the tangent line protruding from the roller and passing through the pressure contact, and the inner wall surface of the transport path on the upstream side of the pressure contact is formed by a curved surface connecting the outer periphery of the guide roller and the pressure contact. .

The stacking mechanism is provided with a sensor for detecting the timing each time each sheet passes through the pressure contact, and rotatably supports the pressure contact roller with the impeller shaft of the impeller-equipped roller. The configuration may be such that the sheet is intermittently driven according to the detection signal of the sensor and each sheet is stored along the guide plate.

[0011]

[0012]

According to the present invention, the sheets branched from the main transport path by the gate are guided to the stacking mechanism via the transport path. Next, the paper sheet is bent by the inner wall surface of the conveyance path on the upstream side of the pressure contact, is then sandwiched by the pressure contact roller that presses against the drive roller, and is continuously stored in the storage along the guide plate. You. At this time, the posture of the paper sheet is restrained by being subjected to bending deformation, and a stable storing operation is performed.

In addition, a sensor for detecting a timing at which the paper sheet passes through the pressure contact is provided, and a pressure contact roller for pressing against the driving roller is rotatably supported by an impeller shaft of a roller with an impeller having elastic blades. The impeller shaft is intermittently driven according to the detection signal of the sensor, and intermittently repeating acceleration, deceleration rotation / stop for each sheet, thereby further improving the performance of the storing operation. In this case, the posture of the paper sheet is more strongly constrained by the synergistic effect of the bending deformation and the elastic force of the elastic blade, so that the storing operation is stably performed.

[0014]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described with reference to FIGS.

That is, the virtual circle 15 in which the inner wall surface 150 a of the transport path 150 on the upstream side of the pressure contact point P between the drive roller 18 and the pressure contact roller 110 passes through the outer periphery of the drive roller 18 and the pressure contact point P and contacts the outer periphery of the guide roller 151.
0b.

FIG. 2 is a perspective view showing the main part, and FIG.
As shown in FIG. 2, for example, two drive rollers 18 are provided in the width direction orthogonal to the conveyance direction of the
Each pressing roller 110 is in pressure contact with 8, and conveys the paper sheet 4 while nipping it. A roller 11 with an impeller is supported adjacent to one pressing roller 110, and a roller 11 with an impeller is coaxially supported at both ends at predetermined intervals. Since each guide roller 151 is provided close to the outer surface of each drive roller 18, both ends in the width direction of the paper sheet 4 are deformed into a convex shape that covers the upper surface of the impeller-attached roller 11. The inside is guided by the outer periphery of each guide roller 151 (the inner wall surface 150a of the transport path) and becomes concave, and the central portion again becomes convex, and the paper sheet 4 is bent into wavy irregularities in the width direction and carried in. You. The numbers of the driving rollers, the pressing rollers, and the rollers with the impeller can be determined as necessary.

FIG. 3 is an enlarged view of the vicinity of the pressure contact P. The inner wall surface 150a of the transport path 150 on the upstream side of the pressure contact P that intersects the tangent 120 at the pressure contact P
1 is an outer peripheral portion where hatching is given. The guide roller 151 is located almost directly above the pressure contact roller 110 and protrudes from the outer periphery of the drive roller 18 to a position where the guide roller 151 intersects with the tangent line 120, and may be a simple fixed guide.

The operation during storage of the first embodiment will be described with reference to FIG. The fed paper sheet 4 is branched off from the main transport path 1 by the gate 2 and guided to the transport path 150. Thereafter, the paper sheet 4 is moved to the inner wall surface 150 of the transport path 150.
The bending deformation is given by a, and while being constrained in that posture, it is sandwiched between the driving roller 18 and the pressing roller 110 and carried into the storage section 100. At this time, by constraining the posture of the paper sheet 4 so as to be along the guide plate 5, the storing operation can be performed continuously and stably. In the case where the paper sheet 4 is conveyed to the next mechanism without being stored in this mechanism, the gate 2 is switched to the position indicated by the two-dot chain line.

A second embodiment will be described with reference to FIG. FIG. 5 shows the sensor 130 and the shielding pin 14 according to the first embodiment.
This is a configuration in which 0 is added. The sensor 130 is arranged to detect the timing at which the sheet 4 passes through the pressure contact P, and the shielding pin 140 is arranged to shield the blade 10 of the roller 11 with the impeller. FIG. 6 is an enlarged view of the vicinity of the pressure contact P. As shown in FIG.

Is deformed so as not to hinder the loading of As shown in FIG. 5, the roller 11 with the impeller is stopped until the rear end of the paper sheet 4 passes through the pressure contact P. Therefore, the paper sheet 4 is subjected to bending deformation by the inner wall surface 150a of the transport path 150, and is further loaded into the storage unit 100 against the elastic force of the stationary blade 10b. Also, the storage operation is performed with the posture strongly restrained along the guide plate 5. As a result, since the paper sheet 4 is completely carried in along the guide plate 5, the performance of the storing operation can be further improved.

FIG. 7 is an enlarged view showing a main part of the paper sheet 4 during the storing operation. When the sensor 130 detects the timing at which the rear end of the sheet 4 has passed the pressure contact P, the roller 11 with the impeller is intermittently driven for each sheet 4 and a predetermined angle (usually 通常). (Rotation), stops at the phase of HP shown in FIG. 6, and is again in a state of waiting for a storing operation of the following paper sheet 4. At this time, the trailing end of the preceding paper sheet 4 is a rotating blade 10.
And is reliably stored and deposited in the storage section 100. Thereafter, this cycle is repeated to repeat paper sheets 4
Is carried out. FIG. 8 shows a flowchart of the storing operation in this case.

A third embodiment will be described with reference to FIG. FIG. 9 shows a configuration in which the inner wall surface 150a of the transport path 150 near the pressure contact P intersecting the tangent line 120 at the pressure contact P is not formed. . The storing operation of the flowchart shown in FIG. 8 is performed, and the roller 11 with the impeller is intermittently accelerated.
When the deceleration drive is assumed, the stationary blade 1
Since the posture of the paper sheet 4 can be restricted along the guide plate 5 by the elastic force of 0, a stable storing operation can be performed even with the configuration shown in FIG. Therefore the third
The embodiment is effective for simplifying the mechanism.
