Abstract

PROBLEM TO BE SOLVED: To stably separate a great variety of sheets one by one over a long period to deliver the sheets in a sheet delivery device by adjusting an overlap amount of a feed roller and a separator according to a property of the sheet. SOLUTION: In this sheet delivery device, when an overlapped feeding detection sensor 31 detects that the plural sheets are simultaneously delivered onto a feeding path, a control circuit 33 controls and elongates a separator actuator 6 through a separator drive circuit 34 to deform a rubber part 52 of the separator 5 such that the overlap amount becomes large. When a sheet passage sensor 32 detects that the sheet is not delivered onto the feeding path, the control circuit 33 controls and contracts the separator actuator 6 through the separator drive circuit 34 to deform the rubber part 52 of the separator 5 such that the overlap amount becomes small.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sheet feeding apparatus, and more particularly to a sheet feeding apparatus configured to separate and feed sheets stacked and stored on a stage or a stacker one by one.

2. Description of the Related Art Automatic teller machines such as cash dispensers (CDs) and automatic teller machines (ATMs) used in financial institutions, printing devices such as form printing devices and printers, facsimile devices and scanner devices. In office equipment, it is necessary to separate and feed out stacked sheets such as banknotes one by one. Therefore, in such an apparatus, a paper sheet feeding device including a mechanism for separating stacked paper sheets one by one and a mechanism for transporting the separated paper sheets is used.

[0003]

2. Description of the Related Art FIGS. 12 and 13 are a plan view and a front view, respectively, showing a main part of a conventional sheet feeding device. The paper sheet feeding device uses a pick roller 12 and a feed roller 13 to feed a first paper sheet 21 of a bundle 2 of paper sheets on a stage 11 to a paper sheet guide 14.
, And the separator 15 prevents the second and subsequent sheets from being pulled out along with the forward movement. FIG.
The middle, arrows A, B and C indicate the biasing direction of the stage 11, the rotation direction of the pick roller 12 and the feed roller 13, and the transport direction of the paper sheet, respectively.

As shown in FIG. 13, the separator 15 has a contact surface between the separator 15 and the sheet as viewed from a direction perpendicular to the sheet feeding direction (the direction indicated by the arrow C). It is arranged so that it may be located inside feed roller 13 rather than the contact surface of feed roller 13 and paper sheets. That is, in the illustrated example, the position of the surface of the separator 15 that contacts the sheet is higher than the surface of the feed roller 13 that contacts the sheet. Such a positional relationship between the two contact surfaces is called an overlap. The amount of overlap between the two contact surfaces when viewed from a direction perpendicular to the sheet feeding direction (direction indicated by arrow C) is referred to as an overlap amount (indicated by t in FIG. 13).

[0005] The performance of the separator 15 for separating the first sheet and the second and subsequent sheets is affected by the coefficient of friction between the separator 15 and the sheet and the amount of overlap. . The amount of overlap depends on the shape of the separator 15. Therefore, the separator 15 is designed in a shape that realizes an overlap amount that can normally separate almost all the sheets to be handled.

[0006]

However, in the above-mentioned conventional sheet feeding apparatus, since there is no mechanism for adjusting the amount of overlap, properties such as the friction coefficient and the strength of the sheet are larger than the average. If it does, the amount of overlap will not be appropriate. If the overlap amount is too small, a plurality of paper sheets are likely to be fed out at the same time. On the other hand, if the amount of overlap is too large, it will be difficult to feed out the paper sheets. In particular, in the case of an automatic teller machine, since the coefficient of friction and the strength of a banknote differ greatly between a government sealed ticket and a circulation ticket, multiple feeds are simultaneously fed out or non-feeds are not sent at all. Cheap. In addition, the overlap amount is gradually reduced due to wear of the separator 15 due to use, so that double feed is more likely to occur. For these reasons, it is difficult for the conventional apparatus to stably separate various kinds of paper sheets one by one over a long period of time.

Therefore, the automatic teller machine is provided with a fail-safe mechanism that does not actually discharge the bill outside the automatic teller machine even if a double feed occurs.
Therefore, there is no particular problem even if double feeding actually occurs. However, when a double feed occurs, it is canceled once and the operation of feeding out the banknote is restarted from the beginning, so that it takes time to pay out the banknote. The same applies to the case where non-feed occurs. This is not preferable because it causes a decrease in the customer service of the bank and a decrease in the management efficiency of the bank.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and it has been proposed to extend a wide variety of paper sheets by adjusting the amount of overlap between a feed roller and a separator according to the properties of the paper sheets. It is an object of the present invention to provide a paper sheet feeding device capable of stably separating one sheet at a time and feeding it accurately.

[0009]

In order to achieve the above object, a sheet feeding apparatus according to the present invention comprises a feed roller, a separator, an actuator for deforming the separator, a double feed detecting sensor, a sheet passing sensor. , Control means and drive means. When the double feed detection sensor detects that a plurality of paper sheets have been fed out to the transport path at the same time, the actuator is extended via the driving means under the control of the control means. Further, when the sheet passing sensor detects that the sheet has not been fed out to the transport path, the actuator is contracted via the driving unit under the control of the control unit.

FIGS. 1 and 2 show how the shape of the separator changes due to the operation of the actuator.
When the actuator 6 fixed to the core portion 51 of the separator 5 is extended, the rubber portion 52 of the separator 5 changes from the shape shown in FIG. 1 to the shape shown in FIG. When the actuator 6 contracts, the rubber portion 52 of the separator 5 changes from the shape shown in FIG. 2 to the shape shown in FIG. A similar mechanism may be used to deform the sheet guide according to the paper quality of the sheet.

According to the present invention, when a double feed occurs, the actuator extends and the amount of overlap increases, and thereafter, it becomes difficult for the paper sheets to pass through the overlap portion, so that recurrence of the double feed is prevented. be able to. Also,
When non-feeding occurs, the actuator contracts and the amount of overlap decreases, and thereafter, the paper sheets easily pass through the overlapped portion, so that recurrence of non-feeding can be prevented. Further, if the paper sheet guide is deformed according to the paper quality of the paper sheet, paper sheets of various types of paper quality can be smoothly guided to the overlap portion.

[0012]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a paper sheet feeding device according to the present invention will be described below in detail with reference to the drawings.

(Configuration of Automatic Cash Transaction Apparatus to which Paper Feeding Apparatus is Applied) First, an automatic cash transaction apparatus to which the paper feeding apparatus according to the present invention is applied will be described.

In the example shown in FIG. 5, the feeding mechanism is configured to feed the stacked bills 33 from below, but there is also a configuration in which the bills are fed from above. In the following description of the paper sheet feeding apparatus, a configuration in which a banknote is fed from above will be described, but the same applies to a configuration in which a banknote is fed from below.

FIG. 3 is a block diagram showing a configuration of a separator and a deformation mechanism of a sheet guide of the sheet feeding apparatus according to the present invention. FIG. 4 is a schematic diagram showing a configuration of a portion related to a separator in the deformation mechanism of the paper sheet feeding device, and FIG. 5 is a schematic diagram showing a configuration of a portion related to a paper sheet guide.

The paper sheet feeding device includes a separator 5, a separator actuator 6, a paper sheet guide 7,
A guide actuator 8, a double feed detection sensor 31, a sheet passing sensor 32, a control circuit 33, a separator drive circuit 34, and a guide drive circuit 35 are provided. The paper sheet feeding device includes a feed roller, a pick roller, and a stage (not shown).

The separator actuator 6 is composed of, for example, a piezoelectric element, and a separator drive circuit 34 is provided.
Expands and contracts according to the drive signal supplied from the controller. The base end of the piezoelectric element is attached to a cored part 51 of the separator 5, and the tip is connected to a rubber part 52 of the separator 5. The guide actuator 8 is made of, for example, a piezoelectric element, and expands and contracts according to a drive signal supplied from the guide drive circuit 35. The base end of the guide piezoelectric element is attached to a support 71 of the paper sheet guide 7, and the front end thereof is connected to the paper sheet guide 7.

The double feed detection sensor 31 and the paper sheet passage sensor 32 are provided on a paper sheet transport path. The double feed detection sensor 31 outputs a detection signal to the control circuit 33 when detecting that double feed has occurred. The paper sheet passage sensor 32 is
When the passage of the paper sheet is detected, a passage signal (detection signal) is output to the control circuit 33. The control circuit 33 is a control unit for controlling the actuator 6 for the separator and the actuator 8 for the guide.

When the control circuit 33 receives the detection signal from the double feed detection sensor 31, it determines that double feed has occurred. Then, the control circuit 33 controls the separator driving circuit 34 to
A control signal for extending the actuator for separator 6 is output. Further, the control circuit 33 outputs a control signal for extending the guide actuator 8 to the guide drive circuit 35 in accordance with the extension of the separator actuator 6 when the double feed occurs.

On the other hand, if the passing signal (detection signal) is not supplied from the paper sheet passing sensor 32 within a predetermined time from the start of driving of the pick roller and feed roller (not shown), the control circuit 33 determines that non-feeding has occurred. I do. Then, the control circuit 33 outputs a control signal for contracting the separator actuator 6 to the separator drive circuit 34. Further, the control circuit 33, when non-feed occurs,
A control signal for contracting the guide actuator 8 in accordance with the contraction of the separator actuator 6 is output to the guide drive circuit 35.

The separator drive circuit 34 is a drive means for driving the separator actuator 6.
The separator drive circuit 34 generates a drive signal based on the control signal received from the control circuit 33, and supplies the drive signal to the separator actuator 6. The guide drive circuit 35 is a drive unit for driving the guide actuator 8. The guide drive circuit 35 includes the control circuit 3
A drive signal is generated based on the control signal received from 3 and supplied to the guide actuator 8.

Next, the operation of the paper sheet feeding device having the above-described configuration will be described. When the double feed occurs, the double feed detection sensor 31 detects the double feed and outputs a detection signal to the control circuit 33. When receiving the detection signal, the control circuit 33 generates a control signal for extending the actuator 6 for the separator and a control signal for extending the actuator 8 for the guide in accordance with the extension, and respectively generates the control signal for the driving circuit for the separator. 34 and a guide drive circuit 35. As a result, the separator driving circuit 34 and the guide driving circuit 35 become the separator actuator 6 and the guiding actuator 8 respectively.
Is extended.

When the separator actuator 6 is extended, the rubber portion 52 of the separator 5 is pushed out and deformed from a shape shown by a broken line to a shape shown by a solid line in FIG. The deformation increases the amount of overlap. Also,
When the guide actuator 8 is extended, the sheet guide 7 is deformed from the shape shown by the broken line in FIG. 5 to the shape shown by the solid line so that the angle formed between the extruded separator 5 and the outer peripheral surface of the rubber portion 52 becomes smaller. I do. Due to the deformation, the paper sheet is smoothly guided to the overlap portion.

When a non-feed occurs, the sheet passing sensor 3
2 does not output a passing signal. The control circuit 33 generates a control signal for contracting the separator actuator 6 when a predetermined time has elapsed from the start of driving of a pick roller and a feed roller (not shown) without receiving a passage signal from the paper sheet passage sensor 32. Further, the control circuit 33 generates a control signal for contracting the guide actuator 8 in accordance with contraction of the separator actuator 6. Then, the control circuit 33 outputs those control signals to the corresponding separator drive circuit 34 and guide drive circuit 35, respectively.

Thus, the separator driving circuit 34
The guide drive circuit 35 contracts the separator actuator 6 and the guide actuator 8, respectively. When the separator actuator 6 contracts,
The rubber portion 52 of the separator 5 is pulled back and deformed from the shape shown by the solid line to the shape shown by the broken line in FIG. The deformation reduces the amount of overlap.

According to the above-described embodiment, when the double feed occurs, the separator actuator 6 is extended and the overlap amount is increased, and thereafter, it is difficult for the paper sheets to pass through the overlap portion. Double feed can be prevented from recurring. Further, when non-feed occurs, the actuator 6 for the separator contracts and the overlap amount decreases, and thereafter, the paper sheet easily passes through the overlap portion, so that recurrence of the non-feed can be prevented. Therefore, various kinds of paper sheets can be stably separated one by one and fed accurately.

Further, even if the rubber portion 52 of the separator 5 is worn, the overlap amount can be increased by the extension of the separator actuator 6, so that the paper can be stably fed out for a long period of time. Further, since the guide actuator 8 expands and contracts in accordance with expansion and contraction of the separator actuator 6, and the paper sheet guide 7 is deformed, paper sheets of various types of paper can be smoothly guided to the overlap portion.

In the above, the present invention is not limited to the above-described embodiment, but can be variously modified. For example, as shown in FIG. 6, a plurality of, for example, two, actuators for separators may be provided, and the amount of expansion and contraction of each of the separator actuators 6 may be individually controlled. By doing so, the rubber portion 52 of the separator 5 can be deformed finely, so that the overlap amount can be set more optimally.

As shown in FIG. 7, a separator actuator 61 made of a shape memory alloy is provided between a cored portion 51 and a rubber portion 52 of the separator 5 in place of the separator actuator 6 made of a piezoelectric element. May be interposed. In this case, the drive signal supplied from the separator drive circuit 34 to the separator actuator 61 is a current signal, and the shape memory alloy generates heat and deforms according to the amount of current of the current signal. Due to the deformation of the shape memory alloy, the rubber portion 52 of the separator 5 is deformed from the shape shown by the broken line in the figure to the shape shown by the solid line. When the current supply to the separator actuator 61 is stopped, the shape memory alloy stops generating heat, and the rubber portion 52 of the separator 5
It returns to its original state due to its resilience.

The same applies to the guide actuator 8. As shown in FIG. 8, the guide actuator 8
May be provided, for example, two in the illustrated example, and the amount of expansion and contraction of each guide actuator 8 may be individually controlled. With this configuration, the paper sheet guide 7 can be deformed finely, so that the paper sheet can be more smoothly guided to the overlap portion.

In place of the guide actuator 8 made of a piezoelectric element, as shown in FIG.
The paper sheet guide 7 may be configured as a shape memory alloy, and the paper sheet guide 7 also serves as the guide actuator 81. In this case, the drive signal supplied from the guide drive circuit 35 to the guide actuator 81 is a current signal, and the shape memory alloy, that is, the sheet guide 7 generates heat in accordance with the amount of current of the current signal, and The shape changes from the shape shown by the broken line to the shape shown by the solid line. When the current supply to the guide actuator 81 stops, the shape memory alloy stops generating heat,
The sheet guide 7 returns to its original shape by the elastic return force of the bias spring 82 provided for restoration.

In the above-described embodiment, the sheet guide 7 is deformed in accordance with the deformation of the separator 5. However, even if only one of the separator 5 and the sheet guide 7 is deformed, Has an effect unique to.
That is, even if only the separator 5 is deformed, the effect of adjusting the overlap amount can be obtained. Further, even if only the paper sheet guide 7 is deformed according to the paper quality, an effect is obtained that the paper sheets can be smoothly guided to the overlap portion.
