Description

The present invention relates to a recirculation type paper sheet storage device and a paper sheet processing device equipped with the same.

Equipped with banknote handling devices such as vending machines, game media lending machines at game halls, ticket vending machines, deposit/withdrawal devices, and currency exchange machines that have the function of accepting inserted banknotes and providing various goods and services. 2. Description of the Related Art As a banknote processing device, a recycling type that is capable of taking in, storing, and dispensing banknotes of multiple denominations is known.

The recycle-type banknote processing device is equipped with a banknote storage unit for storing banknotes prepared in advance for dispensing and banknotes inserted during operation by denomination or in a mixed state of denominations.

Patent Document 1 discloses a recycling type paper sheet storage that allows bills stored in a storage section to be fed out from a feeding section. This paper sheet storage includes a flapper that lifts and lowers banknotes in the storage space, a payout roller (dispensing unit) located at the top of the storage space, and a group of deposit belts ( A pusher moves the banknotes by moving them up and down through a flapper.
In Patent Document 1, the dispensing section and the depositing section are vertically spaced apart from each other, which has the disadvantage of increasing the size in the vertical direction and increasing the number of parts.
In order to deal with such problems, a banknote storage is proposed in Patent Document 1, which includes a deposit/withdrawal section in which a deposit/deposit section is arranged centrally at the bottom of the storage space where the deposit section is located. ing.
In this type of banknote storage, the banknotes are fed out one by one from the bottom of the banknote bundle on the banknote stacking table when the banknotes are fed out, as will be described later in the description of the embodiment. During this feeding, it is necessary to apply sufficient paper feeding pressure to the pick roller while keeping the pick roller in contact with the bottom surface of the banknote bundle, so a pressure means is used to apply a load to the pick roller from the top surface of the banknote bundle. I will add it.

On the other hand, when the pick roller separates and feeds the banknotes one by one from the bottom of the bundle of banknotes and the payout roller feeds them out from the storage space, the banknotes that were not fed out when the series of feeding operations of the specified number of bills are completed. The tips of the first, second, and third sheets from the bottom of the bundle often protrude and remain on the feed-out roller that constitutes the deposit/withdrawal section, and then the bundle stops. These remaining banknotes cause errors in the next deposit and withdrawal operations. Specifically, if this condition is left unattended, when the banknote bundle is raised to the standby position by the pusher in preparation for the next deposit operation, the tips of the remaining banknotes may be bent or otherwise deformed, or the banknote bundle may be lifted. The tip of the remaining banknote may continue to remain in the deposit/withdrawal section even after the transaction. If the next deposit operation continues, the remaining banknotes will collide with the next introduced banknote, causing a jam, or the edges of both banknotes may be bent or torn due to the collision.

Furthermore, if the dispensing operation is performed with the tip of the remaining banknote remaining in the deposit/withdrawal section, double feeding may occur due to poor separation.

As a countermeasure against this, the banknotes with protruding tips are returned to their normal stacking positions by controlling the deposit/withdrawal unit and the pick roller to rotate in the deposit direction immediately after withdrawal. However, in the past, it was necessary to ensure sufficient paper feeding pressure from the banknote bundle to the pick roller during feeding, so the top surface of the banknote bundle was consistently applied by a pressure means (pressing plate) during the return operation of the banknotes. I was under pressure. For this reason, even if the deposit/withdrawal unit and the pick roller are rotated in order to return the banknotes with protruding tips to the normal loading position, the adhesion between the bottom surface of the banknote bundle and the pick roller and the closeness between the banknotes will be reduced. Because the force is too strong, the protruding banknotes cannot be pushed back between the banknote bundle and the pick roller, and it is difficult to return the protruding banknotes to the normal loading position where they do not interfere with deposits and withdrawals.
As a countermeasure, various attempts have been made to improve the operation of each part using software, but there are limits to software measures, and the above-mentioned problems could not be solved.

JP2012-242999 Publication

A banknote storage unit N that stores banknotes transported from the bank and transfers banknotes to and from the deposit/withdrawal processing unit M, a transport mechanism that transports banknotes through various routes, and controls that control various control objects. It is roughly constructed from means (CPU, MPU, ROM, RAM, etc.) 1000.

The deposit/withdrawal processing unit M accepts a single bill or a bundle of bills including bills of different denominations at once, and has a deposit/withdrawal port 5 which serves as a return port for returning deposited bills, and a deposit/withdrawal port 5 which serves as a return port for returning deposited bills. The banknotes (bundle) deposited and set in the deposit/withdrawal port 5 are separated into individual banknotes through the return port 7, which serves as a money dispensing port and a deposit reject return port, and are transferred to the device via the deposited banknote conveyance path 9a. It is provided with a bulk deposit section 11 introduced into the main body, and an identification section 15 that is disposed on the conveyance path along the deposited banknote conveyance path 9a and determines the denomination, authenticity, etc. of the deposited banknotes using a combination of optical and magnetic sensors. Further detailed explanation of the deposit/withdrawal processing unit M will be omitted since it has little relevance to the present invention.

The banknote storage unit N is a first and a second recirculation type that stores banknotes conveyed on each banknote conveyance path 9a, 9b after confirming acceptance of deposited banknotes so that they can be freely deposited and withdrawn for each denomination. A banknote storage device (return type banknote storage unit) 30, 40 is provided. In this example, it is assumed that the first recycling bill storage device 30 stores a maximum of 500 bills, and the second recycling bill storage device 40 stores 200 bills. The illustrated banknote storage unit N has two stacked recirculation banknote storage devices in order to accommodate two denominations, but this is just an example. It is also possible to have a configuration. In addition, a collection warehouse (not shown) is used to collect all denominations from each recycle-type banknote storage device at the end of the workday, and to collect high-value bills that are not used as change and surplus banknotes that cannot be stored in each recycle-type banknote storage device. It is also possible to incorporate a banknote storage section.
The transport mechanism includes a transport mechanism motor M1, a solenoid, a pulley, a belt, a gate, etc. for generating and transmitting a driving force for transporting banknotes along each banknote transport path 9a, 9b and other banknote transport paths. .

It is a perspective view of the deposit/withdrawal means viewed from the bottom side, and FIG. 11 is a perspective view showing the configuration of an example of a lifter elevating mechanism and a presser member elevating mechanism.

Since the configurations of the first and second recirculating banknote storage devices 30 and 40 of this example are substantially the same except for the number of stored bills, the following description will mainly describe the second recirculating banknote storage device 40.
In addition, in the following description, a recirculation type banknote storage device may be simply referred to as a banknote storage unit.

The banknote storage unit 40 includes a banknote storage space (storage space) 70 that stores banknote bundles BP in which banknotes P are stacked in the vertical direction (not limited to the vertical direction, but includes diagonally up and down directions), and a banknote storage space (storage space) 70 on the lower side of the storage space 70. A deposit/withdrawal port (paper sheet input/output section) 80 provided on one side (front side) for depositing and withdrawing banknotes from the side (lateral direction) of the storage space; It is arranged nearby to introduce bills one by one into the storage space 70 from the outside (the stored bill conveyance path 9b), or to feed the bills taken out from the bottom of the banknote bundle BP in the storage space one by one to the outside. A deposit/withdrawal means 90 and a loading platform fixedly arranged within the storage space 70 and on which banknotes introduced by the deposit/withdrawal means 90 (in this example, the central portion in the width direction of the banknotes) are loaded on an upper surface (loading surface) 152. 150, a stopper 75 (see FIG. 4(a), etc.) disposed at the rear (inner side) of the loading table to position the rear end of the introduced banknote at the normal loading position, and both sides of the loading table 150 in the width direction. While moving up and down within the storage space 70 including the lower side spaces 72 (FIGS. 6 and 7) located at each of a lifter 200 that supports and raises and lowers a banknote bundle; a lifter elevating mechanism 250 that raises and lowers the lifter 200 along a fixed path while maintaining a substantially horizontal posture and stops it at a predetermined position; and a loading platform 150. A presser member 300 that moves up and down in the storage space located above and touches and presses the upper surface of the banknote bundle on the stacking platform when descending, and a presser member elevating mechanism 350 that supports the presser member 300 so that it can move up and down in a fixed path. The press adjustment mechanism 400 includes an elastic member 410 and uses the elastic member to bias the pressing member 300 in the downward direction (in the banknote bundle pressing direction) and release the bias.

The deposit/withdrawal means 90 includes a feed roller 95, a stop roller (friction roller) 100, a pick roller 120, an impeller 140, etc., and is driven by a motor M2 for driving the deposit/withdrawal means. The feed roller 95 and the stop roller 100 constitute a separation section, and a storage sensor 105 is disposed downstream of the nip portion n of both rollers in the deposit direction, and detects when deposited banknotes have moved onto the loading table 150. Also, it is detected that a part of the banknote remains near the nip portion at the time of withdrawal.
The feed roller 95 forms a nip part n with the stop roller 100 located directly above it, and rotates in the introduction direction (clockwise direction in FIG. 4) to collect the banknotes conveyed from the stored banknote conveyance path 9b. It is introduced onto the loading platform 150 with the two sides in between.

Furthermore, when the banknotes are fed out, the lowest banknote fed out by the pick roller 120, which rotates in the feeding direction while in contact with the lower surface of the banknote bundle BP on the stacking table, is moved in the feeding direction (counterclockwise in FIG. 5(c) The banknotes are sandwiched between the nip portion n between the feed roller 95 and the stop roller 100, which rotate in the rotational direction), and are sent to the stored banknote transport path 9b. At this time, the feed roller 95 and the stop roller 100 cooperate to prevent double feeding of banknotes. That is, when two or more banknotes are fed out in a stacked manner from the bottom and enter the nip part n between both rollers, the upper banknotes excluding the bottom banknote are moved to the nip part n by the action of the stop roller 100. Passage is blocked.

As shown in each of the perspective views of FIGS. 8 to 10, the feed roller 95 and the stop roller 100 are located at the center in the width direction of the path along which banknotes are conveyed, and the feed roller is located at the center from the opening 150a provided in the loading table. The part is protruding. The two pick rollers 120 are disposed within two openings 150b provided in the loading table 150, and are able to come into contact with the lower surface of the banknote bundle on the loading table.
The feed roller 95 has its axis fixed to a rotating shaft 97, and is driven to rotate in forward and reverse directions by transmitting the driving force from the deposit/withdrawal motor M2 via a transmission gear.
The stop roller 100 is driven to rotate in the banknote introduction direction (counterclockwise in FIG. 4), but does not rotate in the payout direction. Such behavior can be realized by, for example, arranging a one-way clutch (not shown) between the stop roller and its rotating shaft 102. Further, since the stop roller needs to be moved up and down depending on the thickness of the banknotes passing therethrough, its rotating shaft 102 is configured to be able to move up and down and is pressed downward by a spring (not shown).

A belt wrapping portion (sprocket) 122 is integrated with one end in the axial direction of the two pick rollers 120, and a timing belt 125 is wound around the belt wrapping portion. The timing belt 125 is stretched between a belt wrapping portion (sprocket) 97a provided on the rotating shaft 97 of the feed roller and the belt wrapping portion 122, so that the pick roller 120 can be rotated in forward and reverse directions in synchronization with the feed roller. drive
The rotation shaft 102 of the stop roller is arranged coaxially with the rotation shaft 142 of the impeller arranged symmetrically on both sides in the axial direction, but the rotation shaft 102 and the rotation shaft 142 are not integrated. Drive force transmission between both rotating shafts is interrupted. This is because the stop roller needs to be configured to move up and down independently from the impeller as described above.

The impeller 140 is rotationally driven in forward and reverse directions by the deposit/withdrawal motor M2 by meshing a gear 144 fixed to its rotating shaft 142 with a gear 99 provided on the rotating shaft 97 of the feed roller. The impeller has a configuration in which a plurality of blades protrude radially from a center portion where the rotating shaft 142 is located. The blades are made of an elastic material such as resin or rubber, and can correct and shape the conveying posture and shape of the banknotes by coming into contact with the banknotes when the impeller rotates.
When depositing money, the impeller 140 rotates together with the feed roller in the depositing direction (counterclockwise in FIG. 4(a)), flips up the rear end of the deposited banknotes, and assists in introducing them onto the loading table. Further, when dispensing money, the impeller rotates together with the feed roller in the dispensing direction (clockwise direction in FIG. 5(c)), thereby supporting the dispensing of bills to be dispensed.

When returning banknotes, the impeller rotates in the return direction (counterclockwise) together with the feed roller and pick roller, so that the tip protrudes near the nip between the feed roller and the stop roller. The rear end portion can be removed upward from the bottom and efficiently returned to the normal loading position (underside of the stacked banknote bundle) on the loading platform where it will not interfere with new deposits and withdrawals.
In the illustrated configuration example, the loading table 150 extends from inside the banknote storage space 70 to the outside of the deposit/withdrawal means 90, but in this specification, the loading table is mainly located within the banknote storage space and is used to load banknotes. This refers to the area with the loading surface 152.
Note that ``returning the newly deposited banknotes to the regular loading position on the loading platform'' does not in a strict sense mean returning the banknotes to a position where they align with the lower surface of the already loaded banknote bundle without misalignment. This also includes the case where the nip part n is removed to the extent that it does not interfere with new deposits and withdrawals, that is, to the extent shown in FIG. 12(b).

In the present invention, by improving the mechanical structure, pressure is not applied from the elastic member to the banknote bundle in the direction of compressing the banknotes during the return operation, so that the pressing force between the banknotes constituting the banknote bundle, The pressing force between the banknote bundle and the pick roller decreases, making it easier for the banknote bundle to loosen, thereby increasing the return support effect of the impeller.
In addition, the code|symbol 20 in FIG. 8 thru|or FIG. 10 is a conveyance roller arrange|positioned along the stored banknote conveyance path 9b, and the code|symbol 21 is gears as a drive transmission member which drives a conveyance roller.

The lifter elevating mechanism 250 retracts the lifter 200 sufficiently above the top surface of the loading platform (loading surface 152) in order to smoothly load one bill introduced by the depositing and dispensing means 90 onto the loading platform 150. 2(a), FIG. 4(a), and FIG. 6(a)), and the lowermost banknotes of the banknote bundle BP on the loading table 150 are moved to the outside by the deposit/withdrawal means 90. The lowered position (Fig. 3 (c), Fig. 5 (c), Fig. 7 (c)) where the lifter 200 is moved to a height position below the loading surface 152 of the loading platform and stopped in order to pay out the loading/unloading A lifter is used to return the remaining banknotes (on the lowest side of the banknote bundle) that protruded in the payout direction after the payout by the money means 90 (after being fed) to the loading surface 152 of the loading platform by the deposit/withdrawal means 90. 200 is moved to an intermediate position between the lowered position and the raised position and stopped at the intermediate height position (Fig. 2 (b), Fig. 4 (b), Fig. 6 (b)), and the lifter is It has a configuration that allows it to be raised and lowered.

As shown in the perspective view of FIG. 11, the lifter 200 includes two lifter pieces 202 that integrally move up and down along the lower side space 72 on both sides of the loading platform 150 in the width direction. Each lifter piece 202 according to this embodiment is an elongated strip-shaped thin plate, and is dimensioned so that it can move up and down (pass) on the outside of the loading pedestal in the width direction, and can support the lower surfaces of both ends of the banknote bundle in the width direction. Each lifter piece is raised and lowered integrally by the lifter raising and lowering mechanism 250 while maintaining a parallel posture.
The lifter elevating mechanism 250 includes a pair of guide members 255 that are integrated with each lifter piece 202 via a connecting piece 252 and extend parallel to each other in the vertical direction, and a lateral guide member 255 that is provided at the wide bottom of each guide member. A pin (cam follower) 257 is loosely fitted into an elongated hole (cam hole) 255a that extends linearly into the elongated hole so that it can move laterally forward and backward in the elongated hole, and is assembled with a washer 257a so that it cannot fall out. A plate-shaped rotating cam 259 supported by the rotating shaft 261 and having a rotating shaft 261 fixed to the other end thereof, a gear 262 whose shaft center is fixed to the appropriate position of the rotating shaft 261, and a lifter drive that rotates the gear 262 in forward and reverse directions. It is generally equipped with a motor M3 (Fig. 1). Each rotating cam 259 is fixed to both ends of a rotating shaft 261. Note that the concept of lifter elevating mechanism in the claims also includes a lifter.

The rotating cam 259 moves the pin 257 fixed to the end thereof back and forth along the longitudinal direction within the elongated hole 255a in the process of swinging in the left and right directions in an angular range of about 180 degrees about the rotating shaft 261. The guide member 255 and the lifter 200 can be moved linearly in the vertical direction. Since the guide member 255 reciprocates between the raised position (highest position), intermediate height position, and lowered position (lowest position) while the pin 257 reciprocates within the elongated hole 255a, a lifter integrated with the guide member is also used. It moves up and down in the same way.

When the lifter 200 shown in FIGS. 2(a), 4(a), and 6(a) is in the raised position (top dead center), it is waiting for new banknotes to be deposited, and 257 is located at an intermediate position of the elongated hole 255a (a position close to the upper end of the elongated locking hole 410c). When the lifter is in the raised position, the rotating cam 259 holds the pin 257 in the highest position. At this time, in order to prevent the banknote bundle BP on the loading table from interfering with the incoming banknotes and becoming an obstacle to depositing, the lifter lifts the banknote bundle on the loading table and separates it from the top surface of the loading table. Moreover, it is sufficiently retracted upward to form a space G for depositing money. At this time, since the guide member 255, the locking hole (locking part) 410b at the upper end of the elastic member, and the elongated locking hole (locking part) 410c at the lower end are at the highest position, the elastic The member 410 is contracted and is in a non-pressurized state in which it does not press the presser member 300 downward.

In the elastic member 410 as a coil spring, a locking hole 410b provided at one end (the upper end in this example) of the spring body 410a is round, and a locking hole (long) made of a wire provided at the other end is round. The hole-shaped locking hole, elongated hole-shaped locking portion, and elongated hole-shaped hook portion) 410c are elongated holes. The locking hole (fixed side locking hole) 410b is fixed by a pin 362 to one link piece 357a of the pantograph mechanism that constitutes the presser member lifting mechanism 350, while the elongated locking portion 410c is A protruding guide pin 256 is loosely fitted into a proper position of the guide member 255. While the pin 362 cannot freely move within the locking hole 410b, the guide pin 256 is supported within the elongated hole-shaped locking portion 410c so that it can move forward and backward in the vertical direction and cannot fall out. Therefore, when the guide member 255 is at the highest position as shown in the figure, the guide pin 256 has not reached the lower end (locking end) of the elongated hole-shaped locking portion 410c (it is at an intermediate height position). Therefore, the presser member 300 does not press the upper surface of the banknote bundle on the lifter due to the urging force of the elastic member 410.

The elastic member 410 has a part (upper part) fixed to a part (pin 362) of the presser member elevating mechanism 350, and the other part (lower part) to a predetermined vertical range with respect to a part of the lifter elevating mechanism 250. This is a tension spring that is movably supported (loosely fitted) within the spring. In other words, the locking portion 410b does not move relative to the pin 362, while the elongated locking portion 410c moves relative to the guide pin 256. As a result, the guide pin 256 reaches the terminal end 410c' of the elongated locking part and pulls it downward (in the elastic member expansion direction), thereby expanding the elastic member main body 410a. The guide pin stops at the middle of the elongated locking portion, thereby maintaining the elastic member main body in a contracted state.

Note that instead of providing the elongated hook portion 410c, a pin may be fixed to the lower end of the elastic member main body 410a, and the pin may be loosely fitted into an elongated hole provided in the guide member 255 and extending in the vertical direction. The elastic member main body 410a can be expanded when the member is at its lowest position, and the elastic member can be contracted (returned to its original shape) at its highest position and at an intermediate stop position. That is, it is not essential to provide the elongated hole-shaped locking portion 410c in the elastic member, and even with this configuration, the pressure adjustment mechanism 400 has elasticity when the lifter is at the raised position and at the intermediate height position. Pressure applied by the member can be released.

Next, FIGS. 3(c), 5(c), and 7(c) show the banknote feeding state, in which the lifter 200 is at the lowest position (bottom dead center) and the pin 257 is in the elongated hole 255a. It is in an intermediate position. In this state, the rotating cam 259 holds the pin 257 at the lowest position. The guide member 255 and the locking hole 410b at the upper end of the elastic member are lowered than in the case of FIG. 4(a). In addition, since the lower end (terminal end) 410c' is pushed down greatly by the guide pin 256, the elongated locking hole 410c is at the lowest position, so the elastic member main body 410a is greatly expanded, and the holding member 300 is in a pressurized state that urges it downward. Since the pantograph is pulled in the direction of expansion by the tensile force from the elastic member main body 410a through the locking hole 410b at the upper end of the elastic member main body, the presser member 300 presses the banknote bundle BP on the loading table, and the pick roller This ensures sufficient paper feeding pressure.

Next, FIGS. 2(b), 4(b), and 6(b) show how to return the banknotes whose tips protrude toward the nip from the normal loading position to the normal loading position on the loading table. Shown during operation. At this time, the lifter is at an intermediate height position, and the pin 257 is at one end in the longitudinal direction of the elongated hole 255a. In this state, the rotating cam 259 holds the pin 257 at an intermediate height position. The guide member 255 and the locking hole 410b at the upper end of the elastic member are slightly higher than in the case of FIG. 5(c) and the like. At this time, the guide pin 256 is at an intermediate position that is higher in the elongated locking hole 410c than the position shown in FIG. No expansion force is generated, and the elastic member is contracted. That is, the presser member 300 is in a non-pressurized state where it is not pressurized by the elastic member. In this state, the guide pin 256 fixed to the guide member 255 is at the intermediate position ( 4(a)), and the lower end portion is not pressed down. That is, since the guide pin 256 does not push down the terminal end 410c' of the elongated hole-shaped locking part, the elastic member main body maintains its original contracted state.

In this state, the lower surface of the banknote bundle BP is in contact with the top of the pick roller 120, but since no load other than the weight of the pressing member and the pantograph is applied to the banknote bundle, the pressure contact between the pick roller and the lower surface of the banknote bundle is The pressure and the pressure (adhesion force) between the banknotes are sufficiently reduced, and when the feed roller and stop roller are rotated in the return direction, the remaining banknotes whose tips protrude greatly toward the nip part n can be easily removed. It can be returned to its normal position without adversely affecting the next deposit/withdrawal operation.

As shown in FIGS. 2 and 3, the presser member 300 includes two wide presser pieces 302 arranged oppositely above each lifter piece 202, a connecting piece 305 connecting these pieces at the base end, and the like. have Each holding piece 302 also faces the loading surface 152 of the loading platform. The vertical and widthwise positional relationships between each presser piece 302, each lifter 202, and the loading surface 152 will be clear from FIGS. 6(a), (b), and FIG. 7(c).

The holding member elevating mechanism 350 rests on the top surface of the banknote bundle under its own weight, and does not operate by itself, but operates in conjunction with the vertical movement of the top surface of the banknote bundle. The lifter elevating mechanism 250 acts on the pressing member elevating mechanism 350 via the elastic member 410 to pressurize and release the pressurized banknote bundle.
The holding member lifting mechanism 350 includes a pantograph 355 in this example.

As is clear from FIGS. 4(a) and 11, the pantograph 355 has link mechanisms 355A and 355B of the same configuration, each set of which is provided along both edges in the upper width direction of the presser member 300. Consists of. Each link mechanism 355A, 355B has two elongated plate-shaped link pieces 357a, 357b rotatably connected at their longitudinal center positions by a pin 358, and each upper end of each link piece is connected to a base by a pin 359a, 359b. It is connected to member 370. The base member 370 is fixed at a predetermined position within the storage space 70. One pin 359a rotatably connects the upper end of each link piece 357a to the base member 370, and the other pin 359b provided at the upper end of each link piece 357b on the other side rotatably connects the upper end of each link piece 357a to the base member 370. It is slidably and loosely fitted into an elongated hole 370a extending in the horizontal direction (lateral direction).
Further, the lower ends of each link piece 357a, 357b are rotatably connected to the presser member 300 by pins 360a, 360b, respectively. The lower end of the other link piece 357b is rotatably connected to the holding member by a pin 360a, and the pin 360b provided at the lower end of the one link piece 357a is loosely fitted into an elongated hole 300a provided in the holding member. It can move forward and backward within the long hole.
Therefore, each link piece 357a, 357b can expand and contract in the vertical direction by mutually rotating around the pin 358.

A locking hole 410b of an elastic member is fixed to the tip of a pin 362 fixed at a proper position on the upper part of one link piece 357a. The elongated hole-shaped locking portion 410c of the elastic member loosely fits a guide pin 256 provided at a proper position in the middle portion of the guide member 255 in the height direction.
Therefore, when waiting for deposit in FIG. 4A, the pantograph 355 is in the most contracted state because the presser member 300 is pushed up to the highest position by the lifter 200.

At the intermediate height position of the lifter in FIG. 4(b) (during the return operation of the remaining banknotes), the presser member 300 is lowered by the same distance as the lifter and the guide member 255 are lowered to the intermediate height position. Although the pantograph is extended, the guide pin 256 is at an intermediate position spaced apart from the lower end of the elongated locking portion 410c. Therefore, the elastic member maintains its original contracted shape. Therefore, the pressing member is not pressurized by the elastic member.

At the lowest position of the lifter in FIG. 5(c) (when paying out banknotes), the presser member 300 is further lowered because the lifter and the guide member have reached the lowest position. At this point, the guide pin 256 is already in contact with the lowest part (terminus part 410c') of the elongated hole-shaped locking part 410c of the elastic member 410 and is pushing it further down. Therefore, by expanding the elastic member and expanding the pantograph, the pressing member presses the top surface of the banknote bundle.
Note that the concept of the presser member elevating mechanism in the claims also includes the presser member. In other words, the locking hole 410b may be configured to be fixed to the holding member instead of being a part of the pantograph.

As described above, in the pressure adjustment mechanism 400, when the lifter 200 is in the lowered position, the elastic member 410 urges (pressurizes) the presser member 300 to press it against the upper surface of the banknote bundle on the loading platform, and the lifter is raised. position and the intermediate height position, the pressure applied by the elastic member is released.
In this embodiment, the elastic member 410 has a part (upper part) fixed to a holding member or a holding member lifting mechanism 350 (an object to be attached), and the other part (lower part) to a lifter as an object to be attached. This is a tension coil spring supported by a part of the elevating mechanism 250 (guide member 255) so as to be relatively movable within a predetermined vertical range.

The above embodiment is merely an example, and any elastic member that can perform the same function may be used.

Further, for example, the same behavior can be achieved even if the elastic member is attached upside down. That is, while the locking hole 410b of the elastic member is fixed to the guide member 255, the pin 362 of the pantograph may be movably fitted loosely into the elongated hole-shaped locking portion 410c.
In either embodiment, as long as one end of the elastic member is within the range in which it can move relative to the object to which it is attached (the length in the longitudinal direction of the elongated hole-shaped locking part), the force that causes the elastic member to expand is applied. does not occur. When one end of the elastic member reaches the terminal end 410c' of the relatively movable range and continues to move in the same direction while pressing it, the elastic member starts to expand.

<Operation of recycling banknote storage device>
-Deposit operation-
Waiting for deposit and deposit operation will be explained with reference to FIG. 2(a), FIG. 4(a), and FIG. 6(a).
In the standby state, the lifter 200 is stopped at the highest position (top dead center). At this time, in order to form a space G on the stacking surface 152 that will serve as a deposit path for newly deposited banknotes P, the previously stored banknote bundle BP is pushed up to the illustrated position by the lifter 200. In order to raise the lifter 200 to this height position, as described above, the lifter driving motor M3 operates the lifter elevating mechanism 250 to move the pin 257 to the intermediate position of the elongated hole 255a. At this time, since the guide pin 256 is located at the upper part of the elongated hole-shaped locking portion 410c of the elastic member 410, no spring pressure is applied to the presser member 300.

During the depositing operation, the control means 1000 operates the motor M2 for driving the depositing and dispensing means to rotate the depositing and dispensing means 90 in the depositing direction.
When one deposited bill P that has descended along the stored bill conveyance path 9b reaches the deposit/withdrawal means 90, it enters the nip n between the feed roller 95 and the stop roller 100, which rotate in the deposit direction shown by the arrow. It is fed into the empty space G and loaded onto the loading surface 152. At this time, the pick roller 120 interlocking with the feed roller also rotates in the depositing direction to support depositing. When a banknote enters the nip part n, the impellers 140 arranged on both sides of the stop roller in the axial direction rotate in the counterclockwise direction (banknote taking direction) in FIG. 4(a) to support the banknote entry. do. That is, the blades of the impeller flip upward the rear end of the banknote (rear end in the depositing direction) passing through the nip part n, so if the rear end of the banknote attempts to remain near the nip part during depositing, it will flip it up. This makes it easy to detach the paper and feed it toward the stacking position (loading surface 152) on the stacking table.
The banknotes that have entered onto the stacking surface 152 come into contact with the stopper 75 and are stopped.

When it is detected that the rear end of the banknote to be deposited has moved onto the stacking surface 152 by passing the storage sensor 105, the control means 1000 operates the lifter elevating mechanism 250 to move the lifter 200 onto the stacking surface 152. lower than the In the process of the lifter loaded with the banknote bundle BP descending, the lifter moves downward from the stacking surface 152, passing through the new banknote P while deforming both ends in the width direction of the new banknote P on the loading table downward. do. Then, the banknote bundle BP falls onto the new banknote P, and the new banknote becomes part of the banknote bundle. Thereafter, the lifter is raised to the highest position shown in FIG. 4(a) etc., thereby transitioning to a standby state.
This waiting and depositing operation is performed for each bill.

-Withdrawal operation-
The withdrawal operation will be explained with reference to FIG. 3(c), FIG. 5(c), and FIG. 7(c).
When feeding bills one by one from inside the bill storage section 40 to the stored bill conveyance path 9b, the bill bundle held on the lifter 200 in the standby position is transferred onto a loading table (loading surface). Then, the pick roller 120 sequentially feeds out the banknotes starting from the lowest one. During feeding, it is necessary to apply pressure to the banknote bundle by the elastic member 410 in order to ensure paper feeding pressure to the pick roller.
In the standby state, the lifter 200 is stopped at the highest position (top dead center), but for the withdrawal operation, the lifter elevating mechanism 250 operates to move the guide member 255 to the lowest position (bottom dead center) as shown. lower to. In the process of the lifter passing downwardly on the loading surface 152, the banknote bundle that had been held on the lifter up to that point is transferred onto the loading surface. The lifter retreats to a position where it does not interfere with the withdrawal. Further, since the guide pin 256 pushes down the lower end of the elongated hole-shaped locking portion 410c of the elastic member 410, a load from the elastic member is applied to the banknote bundle BP via the pressing member 300.

In this state, when the motor M2 for driving the deposit/withdrawal means is driven to rotate the pick roller 120 in the feeding direction (counterclockwise direction in FIG. It is fed out toward the nip portion n with the stop roller 100. At this time, strong paper feeding pressure from the elastic member stabilizes the feeding operation.
The lowest banknote that has entered the nip portion n passes through the nip and is delivered to the stored banknote transport path 9b. At this time, the upper banknotes that are being fed in duplicate are returned toward the loading platform (loading surface) by the stop roller.
When the banknote is fed out from the nip part n, the impeller supports the banknote feeding by rotating in the clockwise direction in FIG. 5(c).

In particular, bills whose tips in the dispensing direction are bent upward will hit the stop roller and become difficult to pass through the nip n, but since the tips of the bills are pressed down in advance by the blades of the impeller rotating clockwise, the bills can be dispensed. It becomes easier to do.
When the storage sensor 105 detects that a specified number of banknotes have been dispensed, the control means 1000 stops the motor M2 for driving the deposit/withdrawal means and drives the lifter drive motor M3 in preparation for the next deposit operation. This will raise the lifter to the standby position. While the lifter is rising, it holds the banknote bundle on the loading platform and stops at the standby position.

- Remaining banknote return operation -
2(b), 4(b), and 6(b), enlarged explanatory views of the main parts (around the separation part) shown in FIGS. 12(a) and 12(b), and the flowchart of FIG. 13. The operation of returning banknotes will be explained.
When the dispensing operation is completed, the tips of about 1 to 3 bills from the bottom of the bill bundle (tips in the feeding direction) protrude into the nip n between the feed roller 95 and the stop roller 100, or protrude in front of the nip. may remain. When the lifter was raised to the standby position in this state, there was a problem in that the tip of the protruding bill would be bent or broken. In addition, when the banknote bundle BP containing banknotes whose tips remain in the nip portion (residual banknotes) is raised to the standby position and enters the deposit operation, the deformed ends of the deposited banknotes and the residual banknotes are separated. interference and collision, which can easily cause deposit failures. Furthermore, when dispensing money, bills with deformed tips are fed out, which causes paper jams and the like.
Note that the conventional banknote storage device according to the present embodiment is different from the banknote storage device according to the present embodiment not only in the pressurization method using the elastic member and the pressurization timing but also in other configurations. In the banknote storage device equipped with the above-mentioned structural elements, a problem will be described in which the pressure is not released when the banknote is returned.

In order to return the remaining banknotes to the normal stacking position on the loading table 150, that is, to the bottom of the banknote bundle on the loading table with good consistency, the feed roller 95 and the pick roller 120 must be rotated in the depositing direction (returning direction). need to be done. However, in conventional banknote storage devices, the lifter has only two stopping positions: the highest position for waiting and the lowest position for feeding. Moreover, the load from the elastic member that expands the pantograph is constantly applied to the banknote bundle via the pressing member. For this reason, the load from the elastic member 410 is consistently applied to the banknote bundle during the period when the banknote bundle is placed on the stacking surface 152 for feeding. In other words, the pressure between the lower surface of the banknote bundle and the pick roller 120 and the pressure between the remaining banknotes to be returned and the banknote bundle positioned above are too strong. For this reason, even if the feed roller and pick roller are rotated in the return direction, it is not possible to perform the sorting work between the banknotes that is necessary to smoothly slide the remaining banknotes in the plane direction and return them to the bottom of the banknote bundle. Ta.

In order to complete this return operation, it is necessary to perform separation to reduce the pressure contact between the banknotes that make up the banknote bundle, but as long as the load from the elastic member continues to be applied to the banknote bundle, separation will not be performed. The return motion was difficult.

FIG. 12A shows a state in which the banknote protrudes after the feeding operation, and one banknote P remains beyond the nip n of the separating section. In this state, if strong pressure from the elastic member is applied from the presser member 300 to the banknote bundle BP, even if the feed roller, pick roller, and impeller are rotated in the return direction, the protruding banknotes P will be picked against the bottom surface of the banknote bundle. It will be difficult to get things back together with Laura.
In contrast, in the present invention, by providing a new mode in which the lifter is stopped at an intermediate height position and significantly reducing the load applied to the banknote bundle, the feed roller as shown in FIG. As a result of rotating the pick roller and the impeller in the return direction, it becomes possible to smoothly remove the banknote P from the nip portion n.

In the present invention, as the stop position of the lifter 200, in addition to the raised position during standby and the lowered position during feeding, a stop position corresponding to an intermediate height position between both positions is added, and the lifter 200 is placed at this intermediate height position. The mechanical structure has been improved so that the load from the elastic member is not applied to the banknote bundle from the pressing member 300 when the banknote is in the banknote position. Therefore, during the return operation, only a light load consisting of the weight of the pressing member and the pantograph is applied to the banknote bundle.
By configuring the elastic member, which is partially supported by the pantograph 355 and the other part to be free with respect to the guide member 255 (lifter) when the lifter is at the intermediate height position, residual banknotes (protruding banknotes) can be removed. It enhances the return effect.
Note that the height position of the lifter at the intermediate height position is equal to or lower than the upper surface (loading surface) of the loading platform 150, as shown in FIG. 4(b). This is because if the lifter is located above that position, it will interfere with the banknotes and become an obstacle to the return operation.

Next, the procedure for returning the remaining banknotes will be explained with reference to the flowchart of FIG. 13.
Since residual banknotes are generated during the dispensing operation, the presence or absence of residual banknotes is determined based on the output of the storage sensor 105 at the timing when a series of banknote dispensing operations are completed. When the storage sensor 105 detects the presence of banknotes after the end of the feeding operation (step S1, YES, step S3, YES), the control means drives the lifter elevating mechanism 250 to bring the banknote to the lowest position for the feeding operation. The lifted lifter 200 is raised to an intermediate height position and stopped (step S5). Next, the deposit/withdrawal means 90 (feed roller, pick roller, impeller) is rotated in the return direction for a predetermined period of time or a predetermined number of times (step S7). When the lifter is stopped at the intermediate height position, the pressure applied from the elastic member 410 to the presser member 300 is released, so the pressing force between the remaining banknotes and the bundle of banknotes directly above them is significantly reduced, and the banknotes are It's easier to sort out the gaps. Therefore, the remaining banknotes can be returned to the lower part of the banknote bundle simply by rotating the deposit/withdrawal means in the return direction.

Note that, as described above, the elastic member 410 may be turned upside down. That is, while the locking hole 410b of the elastic member is fixed to the guide member 255, the elongated hole-shaped locking portion 410c is engaged with the pin 362 of the pantograph 355, so that the pin 362 is inserted into the elongated hole-shaped locking portion 410c. It may be configured so that it can move freely.
Although a coil spring is shown as the elastic member, any other elastic member such as a torsion spring may be used as long as it has the same effect.

In the return operation, since the impeller 140 that rotates in conjunction with the feed roller also rotates in the return direction, the blades of the impeller flip up the leading end of the remaining banknote and assist in separating it from the nip portion n. Therefore, the return operation by the feed roller and pick roller can be further ensured.
Note that even if the elastic member is not provided with the elongated locking portion 410c and both ends of the elastic member main body 410a are immovably fixed to the pantograph and the guide member, the elastic member may be in the lowered position for dispensing money. By raising the lifter to an intermediate height position and raising the presser member, the load on the banknote bundle can be slightly reduced. However, during the return operation, most of the load from the elastic member continues to be applied to the banknote bundle. In other words, when the guide pin 256 is fixed to the lower end of the elastic member main body 410a in FIG. 4(b), even if the lifter stops at an intermediate height position, the elastic member main body is completely cannot return to its original form.

[Summary of the structure, action, and effects of the present invention]
The recirculation banknote storage devices 30 and 40 according to the first aspect of the present invention have a paper sheet storage space 70 for storing paper sheets BP, and a paper sheet storage space 70 for introducing paper sheets into the paper sheet storage space and a paper sheet storage space 70 for storing paper sheets BP. A paper sheet loading/unloading means 90 that feeds paper sheets, a loading table 150 arranged in the sheet storage space and loading the sheets introduced by the sheet sheet loading/unloading means, and a sheet stack supporting the lower surface of the loading table. a lifter 200 that raises and lowers the lifter, a lifter elevating mechanism 250 that raises and lowers the lifter, a presser member 300 that lifts and lowers above the loading table and is placed on the upper surface of the sheet on the loading table, and a presser member 300 that lifts and lowers the presser member. The presser member lifting mechanism 350 is provided with a presser member lifting mechanism 350 that can support the presser member, and a pressure adjustment mechanism 400 that includes an elastic member 410 and uses the elastic member to bias the presser member in the downward direction or release the bias. The lifter elevating mechanism 250 has an elevated position in which the lifter is moved above the loading surface of the loading platform when the sheets introduced by the sheet loading/unloading means 90 are loaded onto the loading table, and a lifting position in which the lifter is moved above the loading surface of the loading table when sheets introduced by the sheet loading/unloading means 90 are loaded. A lowering position in which the lifter is moved to a height position below the loading surface of the loading platform when feeding paper sheets on the platform to the outside, and a lowering position in which the lifter is moved to a height position below the loading surface of the loading platform, and a lowering position where the lifter is moved to a height position below the loading surface of the loading platform, and after the paper leaves are fed out by the sheet loading/unloading means, the sheets are transferred to the loading platform by the sheet loading/unloading device. In order to return the lifter, the lifter is moved up and down between an intermediate height position and an intermediate position between a lowered position and a raised position. The pressure adjustment mechanism 400 uses an elastic member to press the presser member to press it against the upper surface of the stack of sheets on the stacking table when the lifter is at the lowered position, and when the lifter is at the raised position and the intermediate height position, respectively. It is characterized by releasing the pressure applied by the elastic member.

When the lifter 200 is in the lowered position (feeding out), the distance between the lifter and the presser member is the longest, so the elastic member main body 410a expands to pressurize the presser member and bring it into pressure contact with the upper surface of the sheet bundle. When the lifter 200 is in the raised position (when paper sheets are introduced) and in the intermediate height position, the distance between the lifter and the presser member is the shortest, so the elastic member that was stretched when lowered contracts and returns to its original shape. By returning to , the pressure applied by the presser member to the upper surface of the stack of paper sheets is released.
In this specification, the vertical direction is a concept that includes not only the vertical direction but also the diagonal vertical direction.
The direction of the loading table means the direction of the sheet storage space.
In the embodiment, an example is shown in which the paper sheet input/output means introduces paper sheets into the paper sheet storage space from the side, but the introduction from the side is only one example. Further, although an example has been shown in which the loading platform is fixedly disposed within the sheet storage space, this is also just an example, and the loading platform may be configured to be movable up and down or in other directions as long as the function of the loading platform is not impaired.

In the recirculation banknote storage device according to the second aspect of the present invention, the elastic member 410 has a part (upper part) fixed to the presser member elevating mechanism 350 and another part (lower part) to a part of the lifter elevating mechanism 250. On the other hand, the tension spring is supported so as to be relatively movable within a predetermined range in the vertical direction.
For example, if the elastic member is a coil spring, instead of rigidly fixing both ends to the presser member elevating mechanism (the object to be installed) or the lifter elevating mechanism (the object to be installed), only one end can be fixed to the object to be installed. It is configured to be relatively movable within a predetermined vertical range with respect to a part of it.

In the recirculation banknote storage device according to the third aspect of the present invention, the elastic member 410 has a part (upper part) fixed to a part of the lifter elevating mechanism 250 and the other part (lower part) of the holding member elevating mechanism 350. It is characterized in that it is a tension spring that is partially supported so as to be relatively movable within a predetermined vertical range.
This differs from the recirculation banknote storage device according to the second aspect of the present invention in that the elastic member is upside down.

In the recycling-type banknote storage device according to the fourth aspect of the present invention, the paper sheet input/output means 90 includes an impeller 140 that can come into contact with paper sheets to be introduced or fed out by a blade, and the impeller is configured to move the paper sheets onto the loading table 150. It is characterized in that it rotates in the paper sheet introduction direction when paper sheets are introduced, and rotates in the paper sheet delivery direction when paper sheets are fed out from the stacking table.
The blades of the impeller flip upward the rear end (rear end in the introduction direction) of the sheet passing through the nip portion n when the sheet is taken in. This allows the trailing edge of the sheet to be separated from the nip portion and easily fed into the stacking table. Further, when feeding paper sheets, the feed roller rotates in the feeding direction together with the feed roller that constitutes the paper sheet input/output means, thereby supporting the feeding of banknotes to be dispensed.
A paper sheet processing device according to the present invention is characterized by comprising any one of the above-mentioned recirculation type paper sheet storage devices.
According to this, it is possible to provide a paper sheet processing device having the functions and effects exhibited by the above-mentioned recirculation type paper sheet storage device.
