Description

  The present invention relates to an improvement in a reflux-type banknote storage device having a deposit / withdrawal function for storing banknotes or paying out change, and a banknote handling device.

The reflux-type banknote storage device, which has a deposit function that accepts inserted banknotes and a withdrawal function that dispenses the deposited banknotes as change or withdrawal, handles banknotes such as various vending machines, deposit / withdrawal devices, and money changers. This reflux-type banknote storage device is configured to store banknotes prepared at the start of business or banknotes inserted during operation in denominations and pay out as change when necessary. Is known (Patent Document 1).
In Patent Document 1, a backup plate on which banknotes are stacked, two pressing members that move up and down on the backup plate and press the banknotes transferred onto the backup plate, and banknotes that have entered on each pressing member (payment) The banknote is stored in cooperation with the banknote storage guide member that transfers the banknote) to the backup plate side and the feeding roller that rotates in contact with the uppermost banknote of the already loaded banknote bundle on the backup plate. A banknote recirculation device is disclosed in which the money is deposited or withdrawn.
A separating roller pair composed of an upper friction roller and a lower stop roller is used as means for feeding deposited banknotes onto the backup plate. A sweeper in which thin plate-like blades made of an elastic material (rubber) project radially from the center is fixed to the rotating shaft of the lower stop roller. The blades of the sweeper are arranged at both ends in the axial direction that do not interfere with the friction roller and the stop roller, and are configured so as to suppress the floating of the rear end portion of the bill in the bill storage portion by the tip portion of the blade.

However, various problems occur due to the provision of the sweeper on the rotating shaft of the stop roller.
That is, FIG. 11 is a schematic diagram for explaining the configuration of a conventional banknote recirculation apparatus equipped with a sweeper.
The banknote recirculation device 200 includes a banknote storage unit 201, a separation roller pair (an upper friction roller 231, a lower stop roller 232) 230 disposed on a banknote loading / unloading unit 202 of the banknote storage unit 201, and a banknote on the backup plate 203. A feeding roller 235 that withdraws the uppermost banknote by contacting the upper surface and rotating in the withdrawal direction, and a transport roller capable of forward / reverse movement between the banknote storage unit 201 and the transport path A in both directions. A group 250, a separation roller pair 230, a feeding roller 235, a drive mechanism 260 such as a motor and a gear group for driving the conveyance roller group 250, a paper passing sensor 265, and a control unit (not shown) are provided.

The banknote storage unit 201 is loaded with banknotes P on the upper surface and can move up and down in order to push the received banknotes P1 deposited on the backup plate 203 and the backup plate 203 that can be moved up and down. And a bill storage guide member 220 that is positioned above the backup plate 203 and relatively moves forward and backward in the bill passage opening and guides the conveyance of bills when the push member 210 moves up and down. And an elastic member 225 for urging the backup plate in the upward direction.
A sweeper 253 in which thin blades 253a made of an elastic material (rubber) protrude radially from the center is fixed to the rotation shaft of the lower stop roller 232. The sweeper blades are arranged at both ends in the axial direction that do not interfere with the friction roller 231 and the stop roller 232, and are configured to suppress the floating of the trailing edge of the bill in the bill storage portion by the blade tip.

In the deposit standby position shown in FIG. 11, the push-in member 210 descends and comes into contact with the uppermost surface of the banknote bundle P on the backup plate 203 and pushes it down, thereby forming an accommodation space for the deposited banknote P1 on the push-in member. . In this state, the fed banknote P1 is accommodated in the accommodation space by rotating the feeding roller 235 and the friction roller 231 in the depositing direction indicated by the arrow. Subsequently, by raising only the pushing member 210, the deposited banknote P1 is relatively transferred through the banknote opening provided in the pushing member and transferred onto the banknote bundle P stacked on the backup plate.
In order to prevent the leading edge of the bill newly deposited on the pushing member from colliding with the trailing edge of the already loaded banknote, the sweeper 253 hits the trailing edge of the preceding banknote downwards and holds it in, so that the next banknote enters. Secure the road.

In addition, even if a bill or a banknote that has become weakened can be discharged via a linear path onto the pushing member, it is located at an intermediate position in the axial direction of the plurality of stop rollers 232 than the stop roller. A large-diameter waist roller (not shown) is arranged in parallel and is conveyed while curving downward in the central portion in the banknote width direction.
When shifting from the deposit standby position shown in FIG. 11 to a withdrawal position (not shown), the uppermost surface of the banknote bundle P on the backup plate is moved by moving the pushing member 210 further up than the deposit standby position. Contact with the feeding roller 235. In this state, the uppermost banknote is fed out from the banknote storage unit 201 by rotating the feeding roller 235 and the friction roller 231 in the feeding direction opposite to the arrow.

Next, FIGS. 12A to 12D show the problems of the conventional apparatus in which a sweeper is provided coaxially with the stop roller.
As shown in FIG. 12 (a), when the leading edge of the newly received deposited banknote P2 collides with the end of the storage box and cramps and contracts, the trailing edge of the deposited banknote deviates from the range that the sweeper blade 253a reaches. Therefore, the rear end of the deposited banknote cannot be hit and a risk of collision with the subsequent banknote occurs.
As shown in FIG. 12 (b), even if one of the blades strikes the rear end of the bill P1 immediately after it is deposited, the succeeding bill is shattered as shown when the succeeding bill P2 passes the separation roller pair. The trailing edge of the deposited banknote is lifted without disturbing the rotation of the blades and exerting the hitting effect, thereby generating a collision risk with the subsequent banknote.
As shown in FIG. 12 (c), the blade 253a keeps hitting the rear end of the deposited banknote P1 stacked on the pushing member 210, so that a frictional force is generated between the rear end of the stacked banknote and the contact point of the blade. Occurs, and the rear end of the uppermost deposited banknote is drawn into the gap S between the storage inner wall 240 and a storage failure occurs.
Further, as shown in FIG. 12D, the sweeper blades 253a arranged in parallel with the stop roller 232 are deformed by fluttering during the withdrawal and conveyance, thereby providing a smooth separation and withdrawal resistance of the withdrawal banknotes. The banknotes are separated by the difference in frictional force between the rollers, but it is not preferable that a frictional force is generated between the blade and the withdrawal banknote.

A paper feed roller group 50 (50A, 50B) for bi-directionally moving bills in the deposit direction and the withdrawal direction, a motor for driving the paper feed roller group 50 and other movable parts, a gear group, etc. are not shown. A drive mechanism and control means (CPU, ROM, RAM) 100 for controlling the drive mechanism are provided.

  More specifically, the reflux-type banknote storage device 1 has a banknote storage section 2 provided with a banknote carry-in / out section 2a, and a deposited banknote transported along the longitudinal direction from the banknote carry-in / out section into the banknote storage section in the vertical direction. While being loaded, the up-and-down backup plate 3 elastically urged upward and the deposited banknote from the banknote loading / unloading section are temporarily held and raised and lowered on the backup plate to suppress the upper surface of the stacked banknote on the backup plate. The stacked banknote P1 is moved to the banknote loading / unloading section 2a by rotating in the withdrawal direction in contact with the upper surface of the stacked banknote via the banknote holding unit 10 and the opening 11 provided in the banknote holding unit 10. A feeding roller 51 to be moved, a pair of upper and lower separation rollers 52 arranged in a bill carry-in / out section and rotating in the forward and reverse directions, and a method of depositing the separation roller pair 52 Operates in the process of raising and lowering a pair of upper and lower transport rollers 60 disposed upstream of the separation roller pair (the nip portion) at a distance shorter than the longitudinal length of the banknote and the banknote holding unit. And an elevating mechanism 30 to be moved.

The banknote storage part 2 is an area for storing banknotes, and a banknote on the transport path A is carried into the banknote storage part at the boundary between the banknote storage part and outside the banknote storage part, or banknotes in the banknote storage part are used as a transport path. The banknote carrying in / out part 2a to carry out is provided.
The banknote storage unit 2 is loaded with banknotes deposited on the upper surface and can be moved up and down integrally with the backup plate 3 that can move up and down, the elastic member 4 that urges the backup plate upward, and the backup plate. And a banknote holding unit 10 having an opening 11 for passing banknotes, and an elevating operation mechanism 30 for moving the banknote holding unit up and down.

The banknote holding unit 10 includes a pair of fixed holding members 13 that are opposed to each other in the horizontal direction through the opening 11, and a banknote holding posture (FIG. 2) that temporarily holds a deposited banknote above each fixed holding member 13. And a movable holding member 20 that is displaced between the banknote non-holding posture (FIG. 5) for dropping the held deposited banknote onto each fixed holding member .
Each fixed holding member 13 has an L-shape as shown in FIG. 2 and has a bottom piece 13a which is a narrow strip-shaped plate body for supporting a banknote on the upper surface, and a narrow width rising from the outer edge of the bottom piece. A side piece 13b which is a belt-like plate.
A rotary shaft 14 is provided at the upper end edge of the side piece 13b, and one end edge (base end edge) of the movable holding member 20 which is a narrow strip-like plate-like body is supported by the rotary shaft 14 so as to be rotatable 360 degrees. Yes. Each movable holding member 20 has a protruding length that can support the both ends in the width direction of the banknote that has been deposited and can be separated from the fixed holding member 13 when in the banknote holding posture. On the other hand, after the deposited banknote supported by moving to the banknote non-holding posture is dropped on the fixed holding member, it does not interfere with the deposited banknote on the fixed holding member in the process of rotating around the rotation axis. It is configured to be short. Further, when each movable holding member 20 is in the bill holding posture, the size of the opening 11 formed between the movable holding members is configured not to interfere with the feeding roller 51 that moves relatively up and down in the opening. .

While the banknote holding unit 10 is driven to move up and down as a whole by the elevating operation mechanism 30, the movable holding member 20 rotates forward and backward around the rotation axis in the process of moving up and down, so that the banknote holding posture and the banknote non-holding posture are changed. Change posture between.
The banknote holding unit 10 is a means for holding a deposited banknote that is deposited at the deposit standby position, and presses and holds the deposited banknote when it is relatively lowered on the backup plate. The bottom piece 13a of the fixed holding member 13 is formed of a narrow strip-shaped plate member having a flat bottom surface, and these are arranged to face each other in parallel at a predetermined interval (opening 11).

The raising / lowering operation mechanism 30 maintains the movable holding member 20 in the banknote holding posture when the banknote holding unit 10 is in the deposit standby position, so that the received banknote can be held on the movable holding member 20. Then, the movable holding member 20 is rotated downward by raising the bill holding unit by a predetermined distance to shift to the bill non-holding posture. By this operation, the deposited banknote held on the movable holding member is dropped onto the pair of fixed holding members 13 and transferred.
The lifting / lowering operation mechanism 30 is rotatably supported by a rack gear 31 that is fixedly arranged on both left and right sides of the banknote storage unit 10 and extends in the vertical direction, and a shaft support portion provided on the fixed storage member 13, and always meshes with the rack gear 31. A pinion gear 33 and a driven gear 35 that rotates integrally with the movable holding member 20 and is always meshed with each pinion gear 33 by fixing the axis to each rotary shaft 14 are provided.
By rotating the one pinion gear 33 forward and backward by a motor (not shown) at an appropriate timing, the bill holding unit 10 can be moved up and down as a whole and the movable holding member 20 can be rotated forward and backward.

The paper feed roller group 50 includes a feeding roller 51 that can be rotated forward and backward disposed in the bill storage unit 2 and a pair of upper and lower separation rollers (friction roller 53, stop) disposed in the bill carry-in / out unit 2a (or its vicinity). A pair of upper and lower rollers 54) 52 and a pair of upper and lower parts disposed on the upstream side of the pair of separation rollers and the separation roller pair (the nip portion) with a lead-in / out path A 1 shorter than the length in the longitudinal direction of the shortest banknote. A pair of transport rollers (upper transport roller 61 and lower transport roller 62).
Between the separation roller pair 52 and the conveyance roller pair 60, a paper passing sensor S for detecting the passage of the deposited banknote or the withdrawal banknote is disposed. Based on the detection signal from the paper passing sensor S, the control unit 100 drives the paper feed roller group 50, the backup plate 3, the banknote holding unit 10 and the like at a predetermined timing.

The first paper feed roller group 50A rotates in the dispensing direction in contact with the upper surface of the stacked bills P on the backup plate 3 through the opening 11 when the backup plate 3 is raised to the dispensing position in FIG. A feeding roller 51 capable of forward and reverse rotation for dispensing the uppermost banknote and a separation roller pair 52 are provided. The separation roller pair 52 includes an upper friction roller (upper conveyance roller) 53 that rotates forward and backward, and a lower stop roller (double feed prevention roller) 54. The stop roller 54 is stopped when the bill is fed out, or is rotated at a low speed in the return direction.
The friction roller (upper conveyance roller) 53 and the stop roller (double feed prevention roller) 54 are supported on their respective rotation shafts by, for example, bearings provided on a side plate or a top plate (not shown), and from the motor first motor M1. It is rotationally driven by the driving force.

The feeding roller 51 is pivotally supported by a vertically moving bracket 55 (FIG. 1) so as to be rotatable and vertically movable. When the backup plate 3 is raised to the dispensing position, It is comprised so that it can touch.
The feeding roller 51 is rotationally driven by transmitting a driving force from the first motor M1 via a pulley (not shown), a timing belt, or the like supported by the bracket 55 or the like.
In the above-described embodiment, the configuration including the rack gear, the pinion gear, and the driven gear is shown as the elevating operation mechanism 30, but this is merely an example. The raising / lowering operation mechanism can be assumed to have various configurations such as a motor, a pulley, and a belt, and a solenoid.

<Payment operation>
The control means 100 drives the lifting operation mechanism 30 to rotate one pinion gear 33 to hold the banknote holding unit 10 at the lowest lowered position (FIG. 3), and a position higher than the deposit standby position. Depositing and storing banknotes by moving up and down between the escrow dispensing position (Fig. 10) and the uppermost position (not shown) (Fig. 9) above the escrow dispensing position and stopping at each position. ) And withdrawal of the stored banknotes, respectively.
FIG. 3 is a view showing a state where the banknote holding unit is in the deposit standby position, FIG. 4 is a view showing a process of transferring the banknote onto the fixed holding member, and FIG. 5 is a banknote transfer onto the fixed holding member. FIG. 6 is a diagram illustrating a completed state, FIG. 6 is an explanatory diagram illustrating a state in which the bill holding unit is being lowered, and FIG. 7 is a diagram illustrating a state in which the bill holding unit is returned to the deposit standby position.

At the deposit standby position shown in FIG. 3, the bill holding unit 10 is lowered and the bottom piece 13 a of the fixed holding member 13 comes into contact with the uppermost surface of the bill bundle P on the backup plate 3 and pushes it down, thereby bringing the bill holding posture. An accommodation space for the deposited banknote P1 is formed on each movable holding member 20. In this state, by rotating the friction roller 53 and the stop roller 54 in the deposit direction, one deposited banknote P1 is accommodated on the movable holding member 20.
Next, in order to drop the deposited banknote on the movable holding member 20 onto the fixed holding member 13, the pinion gear 33 is rotationally driven by a predetermined angle in the upward direction as shown in FIG. Raise to position. In this ascending process, each driven gear 35 that meshes with each pinion gear 33 rotates in a retracting direction in which the deposited banknote P1 holding the movable holding member 20 is dropped, and the movable holding member is suspended as shown in FIG. At that time, the fall of the deposited banknote on the fixed holding member is completed.

Next, as shown in FIG. 6, the bill holding unit can be returned to the deposit standby position in FIG. 7 by starting rotation of the pinion gear 33 in the downward direction.
During this lowering, each driven gear 35 that meshes with each pinion gear 33 rotates in a direction to raise the movable holding member, and the movable holding member assumes a horizontal posture at the deposit standby position shown in FIG.
By repeating this depositing banknote holding operation for each deposited banknote, the deposited banknotes are sequentially stacked on the fixed retaining member 13 one by one while preventing collision and interference between the preceding banknote and the subsequent banknote. It becomes possible. By placing the deposited banknotes in a holding state on the fixed holding member, it is possible to speed up the work to be paid out for refund.

<Accommodating movement of deposited banknote>
8 and 9 show a storing operation of transferring the deposited banknotes held on the fixed holding member onto the backup plate.
When the pinion gear 33 is driven to raise the banknote holding unit 10 by a predetermined distance from the deposit standby position shown in FIG. 7, the backup plate 3 is raised by the urging force of the elastic member 4, and as shown in FIG. Thus, the feeding roller 51 is in pressure contact with the upper surface of the deposited banknote P1 on the fixed holding member.

FIG. 9 shows a state in which the banknote holding unit 10 is further raised from the state of FIG. 8, so that the feeding roller 51 has completed the transfer of the deposited banknote P <b> 1 onto the backup plate (the completed banknote storage state). That is, in the state of FIG. 8, only the central portion in the width direction of the deposited bill P1 is in contact with the stacked bill P on the backup plate 3, and both end portions in the width direction are located above the bottom pieces 13a of the left and right fixed holding members. It is not missing. On the other hand, as shown in FIG. 9, the banknote holding unit 10 is lifted so that both end portions in the width direction of the deposited banknote P1 are completely separated from the side pieces 13b of the both fixed retaining members, thereby completely backing the deposited banknote P1. It can be transferred onto the upper stacked banknote P.
The banknote holding unit 10 rises as shown in FIG. 9 in order to pass over both ends of the deposited banknote P1 in a state where the central portion in the width direction is pressed on the backup plate, and then descends again to lower both ends of the deposited banknote. The upper surface of the part is pressed onto the already loaded banknote P.
In this storing operation, the movable holding member 20 only rotates at a position where it does not interfere with the deposited banknote, and does not participate in the storing operation.

<Withdrawal action>
When the banknotes already stored are withdrawn (as a change), the elevating mechanism 30 is driven to the highest position (FIG. 9).
By rotating the feeding roller 51 in the feeding direction at this position, the stored banknotes on the backup plate 3 can be dispensed one by one toward the pair of separation rollers.
As the number of stacked banknotes on the backup plate 3 decreases, the backup plate is pushed up by the elastic member 4 to adjust the separation pressure. In this state, the uppermost banknote is fed out from the banknote storage unit 2 by rotating the feeding roller 51 and the friction roller 53 in the feeding direction. At this time, the stop roller 54 serving as a multifeed prevention means stops rotating or rotates in the return direction so that the lower banknote of the two multi-feed banknotes is moved to the banknote storage unit 2 side. return. The withdrawal banknotes separated by the separation roller pair are smoothly delivered to the conveyance roller pair 60.

Further, since there is no sweeper on the rotating shaft of the stop roller 54, smooth separation is possible.
Furthermore, since the large-diameter sweeper is not arranged in parallel on the stop roller 54, the frictional force is adversely affected between the elastic blade and the banknote when separating banknotes one by one from the banknote bundle on the backup plate at the time of withdrawal. Will not affect. Therefore, stable separation and conveyance are possible.

<Escrow return operation>
The escrow return operation is an operation of returning the actual item before storing (the actual item of the banknote deposited by the customer is returned as it is in response to a cancellation instruction or the like), and the actual banknote under transaction is already stored by the fixed holding member 13. Can be separated from banknotes.
FIG. 10 shows the escrow withdrawal position. In the escrow withdrawal position, when there is a bill P1 deposited on the bottom holding piece 13a of the fixed holding member at the deposit standby position shown in FIG. The unit 10 is raised and positioned slightly above the lowermost part of the feeding roller 51 (contact position with the upper surface of the stacked banknotes). At this time, the biasing force of the elastic member 4 is set so that the uppermost banknote of the deposited banknote P1 on the bottom piece 13a of the fixed holding member comes into contact with the feeding roller 51 with an appropriate pressure.
By rotating the feeding roller 51 in the feeding direction in this state, the banknotes on the bottom piece 13a can be dispensed one by one toward the separation roller pair.

<Characteristic action and effect>
In the present invention, while one of the separating rollers constituting the separating roller pair is not provided with a sweeper coaxially, the banknote retaining unit 10 is composed of a two-stage structure comprising a lower-stage fixed retaining member 13 and an upper-stage movable retaining member 20. The structure. At the time of depositing, the deposited banknote is temporarily held on the movable holding member 20 in the banknote holding posture and then dropped and held on the fixed holding member 13. For this reason, even if it does not provide a sweeper, the collision of the deposited banknotes is prevented. For example, even if the preceding deposit banknote collides with the wall and buckles, when the subsequent banknote is deposited, the preceding deposit banknote is transferred onto the fixed holding member 13, so that the collision can be avoided. That is, the problem shown in FIG.
Moreover, the problem that the effect of hitting the trailing edge of the bill by the sweeper is weakened during the conveyance of the subsequent deposited bill shown in FIG.
In addition, the rear portion of the deposited banknote (FIG. 12 (c)), which has occurred in the past due to the provision of the sweeper, and the problem that the blades of the sweeper become resistance to conveyance during withdrawal (FIG. 12 (d)). Also disappear.
The bill storage guide member 220 that has been used to store the deposited banknotes by pushing them on the backup plate can be eliminated, and the configuration can be simplified and the cost can be reduced.

<Summary of Configuration, Action, and Effect of the Present Invention>
The reflux-type banknote storage device 1 according to the first aspect of the present invention stacks the banknote carry-in / out section 2a and the deposited banknotes that have been carried in along the longitudinal direction from the banknote carry-in / out section, and is elastically biased upward. A backup plate 3 that can be moved up and down, a banknote holding unit 10 that temporarily holds a deposited banknote from a banknote loading / unloading unit and that moves up and down on the backup plate to suppress the upper surface of the stacked banknote on the backup plate, A feeding roller that is disposed above and moves up and down relatively in the opening 11 provided in the banknote holding unit, and moves to the banknote loading / unloading section by rotating in the unloading direction in contact with the upper surface of the stacked banknotes through the opening. The banknote holding unit 10 includes a pair of fixed holding members 13 that are opposed to each other through the opening 11 and the received banknotes. Includes a banknote holding position for temporarily holding above the retainer member, a movable holding member 20 which is displaced between a banknote non-holding position for dropping the deposited banknotes that have been held on the fixing hold member, the It is characterized by that.

In the characteristic configuration of the present invention, the banknote holding unit 10 has a two-stage structure including a fixed holding member 13 on the lower side and a movable holding member 20 on the upper side. At the time of depositing, the deposited banknote is temporarily held on the movable holding member 20 in the banknote holding posture and then dropped and held on the fixed holding member 13.
For this reason, a sweeper can be abolished and the various malfunctions which have arisen due to having provided a sweeper conventionally can be eliminated. That is, since the preceding deposited banknote is retained on the lower fixed retaining member 13 while the subsequent deposited banknote is retained on the upper movable retaining member 20, the interference between the preceding deposited banknote and the succeeding deposited banknote, There is no collision.

Further, since the first banknote P1 already stacked on the banknote holding unit 10 is not hit by the elastic blades of the sweeper during the conveyance and stacking operations of the subsequent banknotes, it is rearward in the deposit direction by the frictional force of the elastic blades. There is no occurrence of a stacking fault that is pulled back (to the right of the drawing) and falls into the gap S between the bill storage unit front wall 2b.
Moreover, the trouble which occurred at the time of withdrawal due to the presence of the sweeper is also eliminated.
In addition, the bill storage guide member which has been used for storing the deposited banknotes by pushing them on the backup plate can be abolished so that the configuration can be simplified and the cost can be reduced. That is, by greatly changing the height position of the banknote holding unit with respect to the feeding roller 51 whose height position does not vary greatly, the feeding roller 51 can play the role of pushing the banknote by the conventional banknote storage guide member. became.
Note that the banknote storage guide member may be used in combination with a feeding roller to realize the storage operation. That is, the apparatus structure provided with the banknote storage guide member also belongs to the technical scope of the present invention.
The banknote carry-in / out section 2a is an entrance of a deposited banknote provided in the banknote storage section 2 and is an area corresponding to an exit of a withdrawal banknote. The separation roller pair 52 can be rotated forward and backward, and is conveyed one by one while preventing double feeding of banknotes when depositing and dispensing.

The reflux-type banknote storage apparatus according to the second aspect of the present invention includes a lifting / lowering operation mechanism 30 that operates the movable holding member 20 in the process of moving the banknote holding unit 10 up and down. When in the position, the movable holding member is placed in the banknote holding posture, and when the deposited banknote on the movable holding member is dropped onto the fixed holding member 13, the movable holding member is moved to the bill non-holding posture while raising the banknote holding unit. It is made to shift.
Since the movable holding member is in the banknote holding posture when the banknote holding unit 10 is in the deposit standby position, the movable holding member enables stable depositing while guiding the lower surfaces of both ends of the banknotes to be deposited.
