Description

Paper sheet processing apparatus and paper sheet processing method

The technology disclosed herein relates to a paper sheet processing apparatus and a paper sheet processing method.

Patent Document 1 describes a banknote depositing / dispensing machine including a plurality of winding-type storage units. The winding-type storage unit stores banknotes by winding them on a drum together with the tape drawn from the tape reel.

Patent Document 2 describes a banknote depositing and dispensing machine having a plurality of stack type storage units. This stack-type storage unit stacks and stores banknotes on the stage.

Both the storage units described in Patent Document 1 and Patent Document 2 are configured so that stored banknotes can be fed out.

Japanese Patent No. 5650317 JP 2014-109797 A

By the way, the inventor of the present application has found that various troubles occur when the storing and feeding of the banknotes are repeated with respect to the storage unit regardless of whether the storage unit is a winding type storage unit or a stack type storage unit. It was. In particular, this problem appears remarkably when the storage amount of the storage unit is in a predetermined range. The state in which the storage amount of the storage unit is in a predetermined range is, for example, a state in which the storage unit is nearly full.

Here, repeating the storing and feeding of the banknotes in a state where the storage unit is almost full can occur for the following reason. In the banknote depositing / dispensing machine, when there are a plurality of storage units storing the same type of banknotes, the priority usage order is set for the plurality of storage units. That is, when storing banknotes, the banknotes are stored in the storage unit with the highest priority order, and if the storage unit reaches the full capacity, in other words, the banknotes are stored in the storage unit with the highest priority order. When it is not possible to store the banknote, the banknote is stored in the storage unit with the next highest priority order. In this configuration, the storage unit with the highest priority for use tends to be full because the banknotes are stored preferentially. Here, let us consider a state in which the storage unit with the highest priority order of use is in a full state, and no bankable bills are stored in the other storage units. If banknotes can be stored in the storage unit with the highest priority order by paying out banknotes from the full storage unit, the next banknote to be stored is stored in the storage unit with the highest priority order. Will do. The storage is full again. In this state, banknotes cannot be stored, but if banknotes can be stored by paying out banknotes, the banknotes to be stored next are stored in the storage unit with the highest priority order. In this way, when the priority use order is set, the storage unit with the high priority use order repeats the storing and feeding of banknotes to and from the storage unit in a state close to full.

The winding-type storage unit winds the banknote around the drum together with the tape pulled out from the tape reel. Therefore, when the winding-type storage unit is almost full, the outer diameter of the drum around which the tape and the banknote are wound is large. It has become. The “outer diameter of the drum” referred to here means an outer diameter including a portion constituted by a tape and bills wound around the drum body. In the following description, the “drum” may include a drum body and a tape and banknotes wound around the drum body.

If the drum is rotated in the winding direction in order to store banknotes while the outer diameter of the drum is large, the tape close to the drum body (that is, inside in the radial direction) Followed and wound in the winding direction. On the other hand, the tape separated from the drum body (that is, radially outside) is less likely to follow the rotation of the drum body due to the influence of inertia. This causes slippage between the inner tape and the outer tape.

Also, when the drum is rotated in the winding direction, since tension is applied to the tape, the tape at the outermost diameter portion of the drum is stably tightened with a certain amount of force. As a result, when the drum with the larger outer diameter is rotated in the winding direction, the inner tape in the radial direction is tightened more strongly, whereas the radial direction between the inner tape and the outermost tape is As the inner tape is wound in the winding direction, tightening of the intermediate tape becomes weaker.

When the banknote is fed out, the drum rotates in the feeding direction opposite to the winding direction, but after the banknote feeding is completed, the drum is rotated in the winding direction to adjust the drum position. Will come to let you. Even when the bills are fed out, when the drum rotates in the winding direction, the tape on the radially inner side is strongly tightened.

For this reason, when storing and paying out banknotes in a state where the retractable storage part is almost full, the tape inside the radial direction gradually tightens, and accordingly, the tape at the intermediate part in the radial direction The tightening gradually weakens. As a result, there may be a problem that the banknote wound around the drum is displaced at a location where the tape is weakened.

この This problem is particularly noticeable when banknotes with a non-constant thickness are stored. The banknote whose thickness is not constant is, for example, a banknote combining a paper material and a polymer material (so-called composite material banknote). In composite bills, there is also a bill having irregularities in which a portion of a polymer material is convex on one side of the bill and concave on the other side. A bill having a non-constant thickness is difficult to bend along the surface of the drum when wound around the drum, and a gap may be formed between the bill and the tape. If there is a gap between the banknote wound around the drum and the tape inside the radial direction, when the drum is rotated in the winding direction, there is no gap between the tape and the banknote inside the radial direction. Is wound, and the tape tightening becomes even stronger. The tape at the intermediate portion in the radial direction is further weakened as the tape inside the radial direction is tightened. As a result, when storing a composite material banknote, the malfunction that the banknote currently wound around the drum will shift | deviate easily arises. Not only composite banknotes, but also banknotes with braille on part of the paper and banknotes with anti-counterfeiting threads and holograms are not constant in thickness. The banknote wound around becomes easy to shift.

On the other hand, in the stack-type storage unit, when the storage amount is almost full, a large amount of banknotes are stacked on the stage, so that the stacked banknotes are not stable. Therefore, when trying to stack new banknotes, the quality of storage deteriorates. When banknotes are fed out in the stack-type storage unit, the uppermost banknote is fed out while compressing the stacked banknotes in the overlapping direction. When the stack-type storage unit is close to full, when the stacked banknotes are compressed downward, the state of the uppermost banknote is not stable, and as a result, the payout quality of the banknote is reduced (for example, skewed). ).

Note that the stack-type storage unit is not limited to a configuration in which banknotes are stacked and stored in the vertical direction, and similarly in a configuration in which banknotes are stored side by side in a horizontal direction, the storage and feeding of banknotes are repeated in a nearly full state. As a result, the storage quality and the feeding quality are lowered.

Furthermore, when banknotes with non-constant thickness are stored in a stack-type storage unit, the stacked banknotes are also inclined, so that the stacked banknotes are further unstable. Therefore, the storage quality and delivery quality of bills are further deteriorated.

Thus, it is not limited to the winding type and the stacking type, and it is desired to avoid repeating the storing and feeding out of the banknotes when the storage unit is almost full.

In addition, the trouble mentioned above is not restricted to storage and delivery of banknotes. The same problem can occur in all paper sheets that contain securities such as gift certificates and checks that are stored in the storage unit.

The technology disclosed herein has been made in view of the above points, and the object of the technology is to reduce problems when the storage unit stores and feeds out paper sheets in the paper sheet processing apparatus. is there. In particular, it is to prevent problems by controlling the storage and feeding of paper sheets.

The technology disclosed herein relates to a paper sheet processing apparatus, and the paper sheet processing apparatus stores at least one paper sheet and feeds out the stored paper sheet. And a control unit configured to control storage and feeding of the paper sheets with respect to the storage unit.

When the storage amount of the storage unit is within a preset range, the control unit stores the paper sheets in the storage unit and feeds the paper sheets from the storage unit. Either one is prohibited and the other is allowed.

According to this configuration, the storage and feeding of the paper sheet are controlled by prohibiting either the storage of the paper sheet in the storage unit or the feeding of the paper sheet from the storage unit.

When the storage amount of the storage unit reaches a predetermined first storage amount, the control unit reduces the storage amount of the storage unit to a preset second storage amount that is smaller than the first storage amount. , Prohibiting the storage of the paper sheet into the storage unit and allowing the paper sheet to be fed out from the storage unit, and feeding out the paper sheet from the storage unit, When the storage amount reaches the second storage amount, storage of paper sheets in the storage unit may be permitted.

According to this configuration, when the storage amount of the storage unit reaches the first storage amount, storage of paper sheets in the storage unit is prohibited. The prohibition of storage continues until the storage amount of the storage unit reaches the second storage amount. That is, until the storage amount of the storage unit reaches the second storage amount, the storage unit only feeds the paper sheets, and does not store the paper sheets.

Here, the first storage amount may be, for example, the maximum capacity of the storage unit (a capacity set as a so-called full capacity) or a capacity near the maximum capacity (a capacity set as a so-called near full capacity). By setting the first storage amount to be large, the number of paper sheets that can be stored in the storage unit is increased.

The second storage amount can be appropriately set with an amount smaller than the first storage amount. In order to prevent repeated storage and feeding of paper sheets in a state where the storage portion is nearly full, it is preferable to set the second storage amount to be relatively small. The second storage amount may be zero (so-called empty) or an amount near zero (capacity set as so-called near empty). If the second storage amount is set to zero or an amount close to zero, the storage unit only performs feeding until the stored paper sheets are almost lost or not, and does not store banknotes. Therefore, it is reliably prevented that the storage and feeding of the paper sheets are repeated in a state in which the storage unit is near full.

Thus, with the above-described configuration, it is possible to avoid problems caused by repeatedly storing and feeding paper sheets in a state where the storage amount of the storage unit is close to the full amount.

When the storage amount of the storage unit reaches a predetermined third storage amount, the control unit increases the storage amount of the storage unit to a preset fourth storage amount that is larger than the third storage amount. The storage unit prohibits the feeding of the paper sheet from the storage unit and permits the storage of the paper sheet in the storage unit, and stores the paper sheet in the storage unit. When the storage amount reaches the fourth storage amount, the feeding of the paper sheets from the storage unit may be permitted.

Here, the third storage amount may be, for example, zero or near zero. The third storage amount may be the same as the second storage amount. In addition, the fourth storage amount can be appropriately set as an amount larger than the third storage amount. The fourth storage amount may be the same as the first storage amount.

According to this configuration, when the storage amount reaches the third storage amount, the storage unit only stores the paper sheets and does not feed out the paper sheets until the storage amount reaches the fourth storage amount. For this reason, it is prevented that the storage and feeding of the paper sheets are repeated in a state in which the storage portion is near full.

The storage unit includes a plurality of storage units, and when the storage unit is permitted to store the paper sheets in any of the plurality of storage units, the storage unit includes a storage unit with a small storage amount. It is good also as storing.

In this way, since the paper sheets are stored as uniformly as possible in the plurality of storage units, it is possible to prevent the storage unit from becoming full or nearly full.

The storage unit includes at least a first storage unit and a second storage unit, and the control unit stores either one of the first storage unit and the second storage unit. When the storage amount of the part reaches the first storage amount, the storage part is set as a storage part dedicated to feeding out only the paper sheet, and the other storage part is stored as the paper sheet. It is good also as setting to the storage part only for storage which performs only.

When the storage amount of any of the storage units reaches the first storage amount, the storage unit is dedicated for feeding, so that the storage unit is close to the first storage amount (in other words, the storage unit is almost full) In the state), it is possible to prevent repeated storing and feeding of the paper sheets. Even if the storage unit is set to be used exclusively for feeding, it is possible to store paper sheets by setting the other storage unit as a storage unit dedicated to storage. Therefore, the paper sheet processing apparatus having this configuration can always store and feed out paper sheets by using a plurality of storage units. Further, in this configuration, unlike the conventional configuration in which the priority usage order is set, a plurality of storage units can be used evenly.

When the storage unit dedicated for feeding reaches the second storage amount, the control unit sets the storage unit as a storage dedicated storage unit and sets the other storage unit as a storage dedicated storage unit. Also good.

When the storage unit dedicated for feeding reaches the second storage amount, the storage amount of the storage unit is sufficiently reduced, so that paper sheets can be stored. Therefore, the storage unit is switched from the storage unit dedicated to feeding to the storage unit dedicated to storage. On the other hand, paper sheets can be fed out by setting the other storage unit as a dedicated storage unit for feeding. The paper sheet processing apparatus having this configuration can always perform both storage and feeding of paper sheets.

The storage unit may be configured to be a winding type in which the paper sheet is wound around a drum together with a tape.

As described above, the take-up type storage unit may cause a deviation of the paper sheet wound around the drum if the paper sheet is repeatedly stored and fed out in a state close to the full capacity. As described above, it is possible to prevent the paper sheet from being displaced in the storage unit by avoiding repeated storage and feeding of the paper sheet when the storage unit is almost full.

The storage unit may be configured in a stack type in which the paper sheets are arranged in contact with each other.

As described above, the stack-type storage unit may deteriorate the storage quality and / or the supply quality if the storage and delivery of paper sheets are repeated in a state near the full capacity. By avoiding repeated storing and feeding of paper sheets in a state where the section is nearly full, it is possible to prevent the storage quality and / or the feeding quality from deteriorating.

The paper sheet processing method disclosed herein includes a step of storing paper sheets in a storage unit, a step of feeding out the paper sheets from the storage unit, and a storage amount of the storage unit within a preset range. There is a step of prohibiting either one of the storage of the paper sheet in the storage unit and the feeding out of the paper sheet from the storage unit.

One of the storage of the paper sheets in the storage unit and the feeding of the paper sheets from the storage unit is prohibited, so that the storage and the supply of the paper sheets may be repeated while the storage unit is almost full. Is prevented.

The paper sheet processing method disclosed herein also stores paper sheets, and when the storage amount of the storage unit configured to feed out the stored paper sheets reaches a predetermined first storage amount, The paper is prohibited from being stored in the storage unit until the second storage amount set in advance, which is smaller than the first storage amount, and the paper sheet is allowed to be fed out from the storage unit. And allowing the storage of the paper sheet into the storage unit when the storage amount of the storage unit reaches the second storage amount by paying out the paper sheets from the storage unit, and Is provided.

This prevents repetitive storing and feeding of paper sheets in a state where the storage unit is almost full.

In the paper sheet processing method, when the storage amount of the storage unit reaches a predetermined third storage amount, the storage unit is configured to reach a preset fourth storage amount that is larger than the third storage amount. A step of prohibiting the feeding of the paper sheets from the storage unit and permitting the storage of the paper sheets in the storage unit, and storing the paper sheets in the storage unit, thereby storing a storage amount of the storage unit When the amount reaches the fourth storage amount, a step of permitting the feeding of the paper sheets from the storage unit may be provided.

The step of storing the paper sheet in the storage unit winds the paper sheet around a drum together with a tape, and the step of feeding the paper sheet from the storage unit sends out the paper sheet together with the tape from the drum. It is good also as. That is, the storage unit may be a retractable storage unit.

As described above, according to the paper sheet processing apparatus and the paper sheet processing method, the occurrence of problems can be prevented by controlling the storage and feeding of the paper sheets.

Hereinafter, the paper sheet processing apparatus disclosed herein will be described in detail with reference to the drawings. In addition, the following description is an illustration. FIG. 1 shows an appearance of a banknote depositing / dispensing machine 1 as a paper sheet processing apparatus. The banknote depositing / dispensing machine 1 is installed at a teller counter of a bank, for example.

The banknote depositing / withdrawing machine 1 executes at least a depositing process for storing the bill inserted into the depositing port 211 in the storage unit 3 and a dispensing process for dispensing the banknote stored in the storing unit 3 to the dispensing port 231. To do. As will be described later, the storage unit 3 is configured to be able to pay out stored banknotes. This banknote depositing and dispensing machine 1 is a so-called circulation type banknote depositing and dispensing machine 1. That is, the banknotes dispensed during the withdrawal process include the banknotes stored in the storage unit 3 during the deposit process.

As shown in FIGS. 1 and 2, the banknote depositing and dispensing machine 1 is roughly divided into an upper processing unit 11 and a lower safe unit 13. In the casing 111 constituting the processing unit 11, a depositing unit 21 having a depositing port 211, a dispensing unit 23 having a dispensing port 231, an identifying unit 25 for identifying banknotes, a depositing unit 21, a dispensing unit A processing unit side conveyance unit 41 including a loop conveyance path 411 that connects the gold unit 23 and the identification unit 25 to each other is disposed. On the other hand, the housing 131 constituting the safe unit 13 includes a storage unit 3 including a plurality of (eight in the illustrated example) winding-type storage modules 31, and a processing unit side transport unit 41. A safe-side transport unit 43 including a transport path 431 that connects the loop transport path 411 and each storage module 31 to each other is disposed. Here, unlike the case 111 constituting the processing unit 11, the case 131 constituting the safe unit 13 protects the storage unit 3 and the like stored therein with a security level higher than a predetermined level. This is a protective housing 131 configured.

The deposit port 211 of the depositing unit 21 is configured to accept a plurality of bills at a time. Although detailed illustration is omitted, the depositing unit 21 includes a feeding mechanism that feeds a plurality of banknotes inserted into the depositing port 211 one by one to the loop conveyance path 411. Further, the withdrawal port 231 of the withdrawal unit 23 is configured to be able to hold a plurality of bills at a time.

The processing unit side conveyance unit 41 conveys banknotes along the loop conveyance path 411 in the clockwise direction and the counterclockwise direction in FIG. Although not shown, the loop conveyance path 411 is configured by a combination of a large number of rollers, a plurality of belts, and a plurality of guides. The banknotes are transported short along the loop transport path 411 with a predetermined interval.

The identification unit 25 is disposed in the loop conveyance path 411. The identification unit 25 is configured to identify at least one of the authenticity, denomination, and correctness of each banknote conveyed along the loop conveyance path 411.

The transport path 431 of the safe section side transport section 32 is connected to the loop transport path 411 via the branch mechanism 419. The branching mechanism 419 operates so as to selectively convey bills conveyed from a predetermined direction in two different directions at the collection positions of conveyance paths extending in three different directions. The branching mechanism 419 selectively sends the banknotes transported clockwise or counterclockwise on the loop transport path 411 to the transport path 431 of the safe unit side transport unit 43 to be stored in the storage unit 3. Or the bills fed out from the storage unit 3 and transported along the transport path 431 of the safe unit side transport unit 43 are transported in the clockwise direction on the loop transport path 411, or counterclockwise Switch whether to transport in the rotation direction.

As described above, the storage unit 3 includes the first to eighth winding type (in other words, tape type) storage modules 31 _-1 to 31 _-8 in the illustrated example. In the following description, the reference numeral “31” is used to collectively refer to each storage module, and the reference numeral “31 ₋ ” is used to distinguish the first, second, third,... Storage modules. ₁ , 31 ₋₂ , 31 ₋₃ ... Note that the number of the storage modules 31 is not particularly limited, and may be one or more and an appropriate number may be set. In this example, the eight storage modules 31 are arranged so that four rows are arranged in the depth direction of the apparatus (left and right direction in FIG. 2) to form one row, and the rows form two rows in the vertical direction. It has been.

Since the basic configuration of the take-up type storage module 31 is well known, detailed illustration is omitted, but in the example shown here, as shown in FIG. A tape reel 311 around which a tape 310 that guides banknotes is wound, and a drum 312 that winds the banknotes together with the tape 310 are provided.

As shown in FIGS. 6 and 11, etc., two tapes are arranged in parallel at intervals in the longitudinal direction of the banknote. The tape 310 pulled out from the tape reel 311 is guided by the tape regulation guide 313 and then reaches the drum 312.

The drum 312 is connected to a rotational drive source (not shown). When the rotational drive source is driven, the drum 312 rotates in the banknote winding direction (that is, the clockwise direction in FIG. 3) and the banknote delivery direction (that is, the counterclockwise direction in FIG. 3). A torque limiter 314 is attached to the tape reel 311. When the drum 312 rotates in the winding direction so as to wind up the banknote, the tape reel 311 is driven by the drum 312 in a state where a predetermined tension F is applied to the tape 310 by the torque limiter 314, and the tape It rotates in the delivery direction of 310. On the other hand, when the drum 312 rotates in the bill feeding direction, the driving force of the rotational drive source of the drum 312 is transmitted to the tape reel 311 by a power transmission mechanism (not shown), and the tape reel 311 winds up the tape 310. Rotate driving in direction.

The banknote enters the storage module 31 and exits from the storage module 31 through the entrance / exit 315 connecting the inside and outside of the storage module 31. The take-up type storage module 31 stores banknotes by winding two tapes 310 drawn from the tape reel 311 around the drum 312 together with banknotes that have entered the storage module 31. The banknotes are wound around the drum 312 with a predetermined distance from each other in such a direction that the longitudinal direction thereof follows the rotation center axis of the drum 312 (see also FIG. 6).

Note that the configuration of the retractable storage module is not limited to the above configuration. There may be one tape wound around the drum, or two or more tapes. Moreover, you may comprise so that a tape may be wound around a drum in the state which pinched | interposed the banknote between two overlapping tapes.

Similarly to the loop conveyance path 411 of the processing unit side conveyance unit 41, the conveyance path 431 of the safe unit side conveyance unit 43 is configured by a combination of a roller, a belt, and a guide. The conveyance path 431 also conveys banknotes one by one. The conveyance path 431 extends vertically downward from the branching mechanism 419 on the loop conveyance path 411, and then bends toward the back side in the depth direction (the left side in FIG. 2), and is stored in two rows. It extends between the modules 31 toward the back side of the banknote depositing / dispensing machine 1. Each storage module 31 is connected to the conveyance path 431 via the distribution mechanism 432. Each distribution mechanism 432 switches the conveyance direction of the banknote conveyed along the conveyance path 431 between the direction along the conveyance path 431 and the direction toward the storage module 31. Each distribution mechanism 432 is driven and controlled by a control unit 513 described later. Thus, the banknotes are sorted and stored in the plurality of storage modules 31 according to the denomination and / or correctness identified by the identification unit 25.

FIG. 4 shows a configuration relating to operation control of the banknote depositing and dispensing machine 1. The banknote depositing / dispensing machine 1 includes a control unit 513 based on a known microcomputer, for example. The control unit 513 includes the above-described depositing unit 21, the dispensing unit 23, the storage unit 3 including the first to eighth storage modules 31, the processing unit side transport unit 41, and the safe unit side transport unit 43. It is connected so that it can send and receive. Although not shown in the drawings, each of these

parts

21, 23, 3, 41, and 43 includes various sensors having a function of detecting, for example, bills being transported on the transport path. Input to the control unit 513. The control unit 513 outputs a control signal based on the input detection signal or the like, and each

unit

21, 23, 3, 41, 43 operates according to the control signal.

The control unit 513 is also connected to the identification unit 25, and the identification unit 25 provides the identification result to the control unit 513. Although detailed illustration is omitted, the operation unit 55 as a human interface part for an operator who uses the banknote depositing / dispensing machine 1, the banknote depositing / dispensing machine 1, for example, via a LAN or a serial bus, a host terminal not illustrated and other A communication unit 57 for transmitting and receiving signals to and from a device, and a storage unit 59 configured by general-purpose storage devices such as a hard disk drive and a flash memory for storing various types of information are respectively bills. It is connected to the deposit / withdrawal machine 1.

The storage unit 59 stores at least the stock amount that is the number or amount of banknotes stored in the banknote depositing and dispensing machine 1. In addition, the storage unit 59 stores a stock amount for each storage module 31.

The control unit 513 responds to commands from the host terminal received through the communication unit 57 and / or various commands received through the operation unit 55, and the

units

21, 23, 25, 3, 41, 43, 55, 57. , 59 are controlled. Thereby, the banknote depositing / dispensing machine 1 performs various processes including a depositing process and a dispensing process described below.

<Deposit processing>
The depositing process is a process of depositing (storing) banknotes into the banknote depositing / dispensing machine 1, and banknotes inserted into the depositing port 211 are basically performed according to the identification result by the identification unit 25 and preset storage allocation. Are stored in any of the storage modules 31. More specifically, the banknote depositing / dispensing machine 1 operates as follows during the depositing process.

That is, in the state where the banknote to be deposited is inserted into the deposit port 211, for example, a command for starting the deposit process is input to the banknote deposit and withdrawal machine 1 by operating the host terminal and / or the operation unit 55. The feeding mechanism of the depositing unit 21 feeds out banknotes in the depositing port 211 one by one, and the processing unit side transport unit 41 transports each banknote to the identification unit 25. The identification unit 25 identifies the banknote and performs counting. The processing unit side conveyance unit 41 also passes the banknote normally identified by the identification unit 25 (this banknote is referred to as a normal banknote as the name of the reject banknote pair) from the loop conveyance path 411 through the branch mechanism 419. Transport to the transport path 431 of the safe unit side transport unit 43. The safe unit side transport unit 43 stores each normal banknote in the predetermined storage module 31 by controlling the sorting mechanism 432 according to the identification result by the identification unit 25 and the storage allocation set in advance. Each normal banknote is stored in one of the storage modules 31 depending on the type of money or the amount of damage.

On the other hand, the processing unit side transport unit 41 pays out to the dispensing port 231 rejected banknotes that the banknote depositing and dispensing machine 1 cannot accept as it is, such as banknotes that cannot be genuinely identified by the identifying unit 25. In addition, during the deposit process, banknotes that cannot be stored due to the storage module 31 becoming full (that is, overflow banknotes) are also paid out to the withdrawal port 231. After the deposit process is completed, the stock amount stored in the storage unit 59 is updated.

<Withdrawal processing>
The withdrawal process is a process for paying out banknotes stored in the banknote depositing and dispensing machine 1. Specifically, the withdrawal process is started by performing a predetermined withdrawal operation for designating at least the denomination and the number of sheets in the host terminal and / or the operation unit 55. The storage unit 3 pays out the specified number of banknotes from the storage module 31 by the specified number. The safe unit side transport unit 43 transports the fed banknotes to the loop transport path 411 of the processing unit side transport unit 41 via the transport path 431. The processing unit side conveyance unit 41 conveys each banknote to the identification unit 25, and after the identification unit 25 performs identification, each banknote is paid out to the withdrawal port 231. After the withdrawal process is completed, the stock amount stored in the storage unit 59 is updated.

(Description of banknotes to be handled by banknote depositing and dispensing machine)
Next, the banknote of the handling object of the banknote depositing / withdrawing machine 1 is demonstrated. In recent years, so-called composite material banknotes in which a paper material and a polymer material are combined have been issued. In the example of the banknote of some banknotes, for example, a 20 euro banknote shown in FIG. 5, the composite material banknote has the unevenness | corrugation formed of the polymer raw material in the position of one side rather than the center in the longitudinal direction of a banknote. The irregularities are concave on one side (front surface in FIG. 5) of the banknote and convex on the other side (back side in FIG. 5). This composite banknote has an asymmetric shape in the longitudinal direction due to the unevenness.

The front and back and the direction of banknotes inserted into the deposit slot 211 are not uniform. For this reason, the direction of the bills conveyed along the loop conveyance path 411 and the conveyance path 431 is divided into four directions of A direction to D direction as shown in FIG. That is, the A direction is a direction in which the banknotes are front and the direction follows the transport direction (the direction from the bottom to the top as shown by the arrows in FIG. 5). The B direction is a direction in which banknotes are front and the direction is opposite to the transport direction. The C direction is a direction in which the banknote is behind and the direction is opposite to the transport direction. The D direction is a direction in which the banknote is the back and the direction follows the transport direction.

The banknote depositing / dispensing machine 1 is configured to transport the banknotes shortly as described above. As shown in FIG. 6, the storage module 31 winds the banknote BN around the drum 312 so that the longitudinal direction of the banknote BN is along the central axis of the drum 312. Therefore, when the banknote is in the A direction and the B direction among the four directions described above, the projections of the irregularities face inward in the radial direction of the drum 312 and become the contraction side in the bending of the banknote. It becomes difficult to bend along the surface. In this case, even when the tape 310 is tightened, a gap may be generated between the tape 310 and the banknote BN, particularly in the uneven portion.

On the other hand, when the banknote is in the C direction and the D direction, the projections and depressions of the unevenness face outward in the radial direction of the drum 312 and become the extension side in bending the banknote, so the banknote is relatively easy to bend along the surface of the drum 312. .

Also, the banknotes with irregularities are not constant in thickness. Therefore, when banknotes having irregularities overlap in the radial direction of the drum 312, the banknotes may be inclined.

When the above-described difficulty in bending due to the direction of the banknote and the uneven thickness due to the unevenness are combined, for example, as shown exaggeratedly in FIG. 6, the tape 310 and the banknote BN wound around the drum 312 are Instead of a columnar shape, a conical shape having a large diameter on one side in the central axis direction of the drum 312 and a relatively small diameter on the other side may occur.

In addition, the banknote of the handling object of the banknote depositing / withdrawing machine 1 is not limited to a composite material banknote, but is a conventional paper material banknote, that is, the thickness is constant and follows the surface of the drum 312 regardless of the banknote direction. Banknotes that are easy to bend.

In addition, for example, a banknote in which a braille part is provided in a part of the banknote or a banknote in which a thread or a hologram for preventing forgery is provided in a part of the banknote is also handled as a banknote to be handled by the banknote depositing and dispensing machine 1. It is possible. A bill provided with braille, threads, or holograms does not necessarily have a constant thickness, and the ease of bending along the surface of the drum 312 may vary depending on the direction of the bill. Therefore, as shown in FIG. 6, the tape 310 and the banknote BN wound around the drum 312 may be conical.

(Problems that can occur in the retractable storage unit)
As described above, in the retractable storage module 31, the banknote is wound around the drum 312 together with the tape 310. When the amount of bills stored in the storage module 31 increases, the outer diameter of the drum 312 increases due to the tape 310 and bills wound around the drum 312. When the drum 312 is rotated in the winding direction in order to store bills in a state where the outer diameter of the drum 312 is large, as shown conceptually in FIG. The drum 312 is wound in the winding direction following the rotation of the drum 312. Thereby, the tape 310 at a position close to the drum 312 is strongly tightened. On the other hand, the tape 310 at a position away from the drum 312 hardly follows the rotation of the drum 312 due to inertia. For this reason, slip occurs between the inner tape 310 and the outer tape 310.

When the drum 312 rotates in the winding direction, a predetermined tension F is applied to the outermost diameter tape 310 of the drum 312 by the torque limiter 314 of the tape reel 311 as described above. Therefore, the tightening state of the tape 310 at the outermost diameter portion of the drum 312 is stable.

Therefore, when the drum 312 rotates in the winding direction in a state where the storage module 31 has a large storage amount, a difference occurs in the tightening force of the tape 310 depending on the inner and outer positions of the drum 312 in the radial direction. In particular, the tape 310 in the radial direction between the inner tape 310 and the outermost diameter tape 310 is weakened as the inner tape is wound in the winding direction. When the tightening of the tape 310 becomes weak, a gap is formed between the tape 310 and the banknote, and the banknote wound around the drum 312 is easily displaced in the direction of the rotation axis of the drum 312.

Further, when the banknotes are fed out from the take-up type storage module 31, the drum 312 is rotated in the direction opposite to the winding direction. However, the drum 312 is adjusted in order to adjust the position of the drum 312 after the banknotes are fed out. A little rotation is performed in the winding direction. For this reason, also when paying out banknotes, the tightening of the tape 310 inside the drum 312 can be strong, and the tightening of the tape 310 can be weak at the intermediate portion, as in the case of storing the banknotes.

Here, the banknote depositing / dispensing machine having the conventional configuration stores the same type of banknotes in a plurality of storage modules (for example, when a correct bill of the same denomination can be stored in either of the two storage modules). Set a priority order for a plurality of storage modules.

This conventional configuration will be described in detail with reference to FIG. FIG. 8 shows two

storage modules

31L and 31R on the right side and the left side. The right and left

storage modules

31L and 31R shown in FIG. 8 do not mean storage modules adjacent to each other in the banknote depositing and dispensing machine, but two storage modules that store the same type of banknotes. It is assumed that the left storage module 31L has a relatively high priority use order, and the right storage module 31R has a relatively low priority use order.

In the initial state P81 of the bill depositing / dispensing machine, the two

storage modules

31L and 31R are both empty. When the banknotes are stored in the initial state P81, the banknotes are stored in the left storage module 31L having a high priority use order. Further, the banknotes are fed out from the left storage module 31L storing banknotes (see the arrow in FIG. 8).

When the storage capacity of the left storage module 31L increases and it becomes impossible to store banknotes in the left storage module 31L (more precisely, the left storage module 31L has a preset full capacity or When the near full capacity close to the full capacity is reached), the banknotes are stored in the right storage module 31R having a low priority use order, as indicated by P82 in FIG. The full capacity set in advance is the maximum value of the storage amount stored in the storage module 31L, and may be specified by the number of banknotes or may be specified by the maximum diameter of the drum around which the banknotes are wound. Yes, and may be defined by the weight of banknotes stored. When the maximum value of the stored amount is set by the number of banknotes, the maximum diameter of the drum changes due to the influence of the thickness difference between the new and old banknotes stored. The full capacity is sometimes referred to as a full capacity below.

When bills are fed out, bills are fed out from the left storage module 31L having a high priority use order. As a result of the banknote being drawn out from the left storage module 31L, the left storage module 31L is again in a state in which banknotes can be stored. When the left storage module 31L is in a state in which banknotes can be stored, the banknotes are stored in the left storage module 31L having a high priority use order, and the banknotes are fed out from the left storage module 31L. (See P83).

FIG. 10 is a diagram illustrating a change in the storage amount of the storage module. In the conventional configuration in which the priority use order is set for a plurality of storage modules, as shown by the broken line in FIG. 10, the storage module having a high priority use order repeats the storage and delivery of banknotes in a state close to full. Become.

As described above, when banknotes are stored or banknotes are fed out in a state where the storage module 31 has a large storage capacity, tightening of the tape 310 is weakened in the intermediate portion in the radial direction of the drum 312. Therefore, in the conventional configuration, the tape 310 is tightened more and more at the radial intermediate portion of the drum 312.

In particular, when the banknotes stored in the storage module 31 include composite material banknotes, if there is a gap between the tape 310 and the banknotes due to the difficulty of bending the composite material banknotes described above, On the inner side in the radial direction, this is equivalent to the fact that the fastening allowance of the tape 310 remains. Therefore, when the drum 312 is rotated in the winding direction, the winding amount of the inner tape 310 is further increased, while the tape 310 is more tightened in the intermediate portion in the radial direction of the drum 312. There is a problem that it becomes weaker and the gap between the tape 310 and the banknote becomes larger, and the banknote wound around the drum 312 is likely to be displaced.

The banknote depositing / dispensing machine 1 is configured to eliminate this problem by adopting various configurations 1 to 4 described below. Note that the banknote depositing / dispensing machine 1 may adopt all of the configurations 1 to 4 described below, or one or more of them may be selected as appropriate.

(Configuration 1: Configuration to prevent repeated storage and withdrawal of bills in a state where the storage module is nearly full)
As described above, repeated storage and feeding of the banknotes in a state in which the take-up type storage module 31 is nearly full causes the banknotes to shift. Therefore, the banknote depositing / dispensing machine 1 is configured to prevent the banking module 31 from repeatedly storing and feeding the banknotes in a state where the storage module 31 is nearly full.

Specifically, in this bill depositing / dispensing machine 1, the priority use order of the storage modules 31 is not set. When the storage amount of the storage module 31 is within a preset range, the control unit 513 of the banknote depositing / dispensing machine 1 can store either banknotes in the storage module 31 or pay out banknotes from the storage module 31. One is prohibited and the other is allowed. More specifically, when the control unit 513 reaches the preset first storage amount, the control unit 513 prohibits storage of banknotes in the storage module 31 and reaches the banknotes until the preset second storage amount is reached. Only allow.

Here, the first storage amount is set based on the maximum capacity (that is, full capacity) of the storage module 31 or an amount near the maximum capacity (that is, near full capacity). The first storage amount may be a full capacity or a near full capacity.

The second storage amount is appropriately set with an amount smaller than the first storage amount. To prevent the storage module 31 from repeatedly storing and paying out banknotes in a state where the storage module 31 is nearly full, the second storage amount is preferably far away from the first storage amount. The second storage amount may be zero (that is, empty) or an amount near zero (that is, near empty).

Next, an example of change in the storage amount of the plurality of

storage modules

31L and 31R in this configuration will be described with reference to FIG.

P91 in the initial state is the same as P81 in FIG. When storing banknotes in the initial state P91, it is possible to store banknotes in any of the left and

right storage modules

31L and 31R. In the illustrated example, banknotes are stored in the left storage module 31L. When the banknote is fed out, the banknote is fed out from the left storage module 31L storing the banknote (see the arrow in FIG. 9).

When the storage amount of the left storage module 31L increases and the left storage module 31L reaches the first storage amount, the control unit 513 stores banknotes in the left storage module 31L as described above. Ban. The control unit 513 permits the feeding of banknotes from the left storage module 31L. At this time, the control unit 513 permits storage of banknotes in the right storage module 31R (see P92 in FIG. 9).

Even if the storage amount of the left storage module 31L is less than the first storage amount by feeding out the banknote from the left storage module 31L, the control unit 513 controls the banknote until the storage amount reaches the second predetermined amount. Ban storage. Accordingly, the storage module 31L on the left side becomes a storage module dedicated for feeding until the storage amount reaches the second predetermined amount. During this time, the banknotes are stored in the right storage module 31R. The control unit 513 prohibits the feeding of banknotes from the right storage module 31R, and makes the right storage module 31R a dedicated storage module.

When the storage amount of the left storage module 31L reaches the second storage amount by paying out bills from the left storage module 31L, the control unit 513 makes the left storage module 31L a storage module dedicated to storage, The storage module 31L is permitted to store banknotes. On the other hand, the control unit 513 makes the right storage module 31R a dedicated storage module, and prohibits the banknotes from being stored in the right storage module 31R. That is, when the storage amount of the left storage module 31L reaches the second storage amount, the storage module dedicated to storage and the storage module dedicated to feeding are switched (see P93 in FIG. 9).

As illustrated by a solid line in FIG. 10, the left storage module 31 </ b> L becomes a storage module dedicated to withdrawal when the storage amount reaches the first storage amount, and stores bills until the second storage amount is reached. It is forbidden. The left storage module 31L is prevented from repeatedly storing and paying out bills in a state close to full.

Further, as illustrated by a one-dot chain line in FIG. 10, the right storage module 31R becomes a storage-only storage module if the left storage module 31L becomes a storage-only storage module, and the left storage module 31L only stores. If it becomes this storage module, it will become a storage module only for feeding. Therefore, the storage module 31R on the right side is also prevented from repeatedly storing and paying out banknotes in a state close to full.

As a result, the banknotes wound around the drum 312 are prevented from shifting in the storage module 31 due to weak tightening of the tape 310.

Further, in this configuration, since one of the plurality of storage modules 31 is set as a storage module 31 dedicated to storage and the other is set as a storage module 31 dedicated to payout, it becomes possible to always store and pay out bills. . Further, unlike the conventional configuration in which the priority usage order is set, a plurality of storage modules 31 can be used evenly.

In the above description, when the storage amount of the left storage module 31L set exclusively for feeding reaches the second storage amount, the left storage module 31L is used as a storage module, and the right storage module 31R is used as a delivery. The storage module is set. Unlike this, when the storage amount of the right storage module 31R set exclusively for storage reaches the first storage amount before the storage amount of the left storage module 31L reaches the second storage amount, the timing Thus, the right storage module 31R may be set as a storage module dedicated to feeding, and the left storage module 31L may be set as a storage module dedicated to storage.

The left storage module 31L prohibits one of banknote storage and payout between the first storage amount and the second storage amount, whereas the right storage module 31R has a third storage amount and a fourth storage amount. You may make it prohibit one of the accommodation of a banknote, and delivery | payout between storage amounts.

Further, in the above configuration, when the storage amount is between the first storage amount and the second storage amount, one storage module 31 is dedicated for storage and the other storage module 31 is dedicated for feeding. Unlike this, each of the plurality of storage modules 31 is configured to permit both storage and feeding of bills, and when the storage amount of any one storage module 31 reaches the first storage amount, The storage module 31 prohibits storage of banknotes up to the second storage amount and permits banknote payout, while the other storage module permits both banknote storage and payout. Good.

That is, as described above, the problem of banknote misalignment occurs when the storage module 31 repeats storing and feeding out of the banknotes in a state where the storage module 31 is almost full. Even if the feeding is repeated, the banknotes are unlikely to shift. Accordingly, in the state where the storage module 31 is relatively small without setting one storage module 31 to be dedicated for storage and the other storage module 31 to be dedicated for feeding, the plurality of storage modules 31 can store banknotes. The feeding may be permitted.

In this case, when storing banknotes, banknotes are stored in the storage module 31 having a small storage amount among the plurality of storage modules 31, and when storing banknotes, the storage amount is large among the plurality of storage modules 31. You may make it pay out a banknote from the storage module 31. FIG. By doing so, it becomes possible to store banknotes as uniformly as possible in the plurality of storage modules 31.

And in each of the plurality of storage modules 31, in the configuration that permits storage and delivery of banknotes, when the storage amount of any storage module 31 reaches the first storage amount, the storage module 31 If the storage of banknotes is prohibited and the feeding of banknotes is permitted until the storage amount is reached, it is possible to prevent the storage module 31 from repeatedly storing and feeding banknotes in a state where the storage module 31 is nearly full.

(Configuration 2: Configuration for adjusting the starting current of the drum)
As described above, in the take-up type storage module 31, the drum 312 is connected to the rotation drive source. The drum 312 is rotated in the winding direction by the driving force of the rotation driving source, whereby the bill is wound on the drum 312 together with the tape 310. In a state where the diameter of the drum 312 is large (that is, in a state where the storage module 31 has a large storage amount), when the drum 312 starts to rotate vigorously at the start of winding of the banknote and the tape 310, the diameter close to the drum 312. The tightening of the tape 310 inside the direction becomes strong. On the other hand, if the rotation of the drum 312 is moderately started at the start of winding, the tightening of the tape 310 on the radially inner side can be suppressed. As a result, it is possible to prevent the tightening of the tape 310 at the intermediate portion in the radial direction of the drum 312 from being weakened, and it is possible to prevent the banknote from shifting.

Therefore, the control unit 513 changes the starting current at the start of rotation of the drum 312 according to the storage amount of the storage module 31. Specifically, when the storage amount of the storage module 31 is smaller than a predetermined amount (that is, when the diameter of the drum 312 is relatively small), the starting current is set to the first current value. Since the first current value is a relatively high current value and the drum 312 starts to rotate vigorously, the diameter of the drum 312 is small, and the tape 310 wound around the drum 312 follows the rotation of the drum 312, so that the radial direction The tightening of the inner tape 310 is avoided. Accordingly, it is possible to prevent the tape 310 from being tightened weakly in the radial intermediate portion of the drum 312.

The control unit 513 sets the starting current to the second current value when the storage amount of the storage module 31 is equal to or larger than the predetermined amount (that is, when the diameter of the drum 312 is relatively large). The second current value is a current value lower than the first current value. As a result, the drum 312 starts to rotate slowly. As a result, even when the diameter of the drum 312 is relatively large, it is possible to prevent the tape 310 on the inner side in the radial direction of the drum 312 from being tightened strongly, and the tape 310 to be tightened at the radial intermediate portion. Is prevented.

Note that when the storage amount of the storage module 31 is equal to or greater than a predetermined amount, the control unit 513 may decrease the starting current from the second current value as the storage amount increases. For example, the starting current may be decreased by 0.1 A every time the storage amount (storage number) increases by 10 sheets. By doing so, it becomes possible to optimize the starting current in accordance with the diameter of the drum 312, and more reliably prevent tightening of the tape 310 inside the drum 312 in the radial direction. It becomes possible.

(Configuration 3: Configuration for switching the operation mode of the storage module)
When the drum 312 is rotated in the winding direction, the tightening of the tape 310 on the inner side in the radial direction of the drum 312 becomes stronger because the tightening of the tape 310 wound around the drum 312 is originally weak. One.

As described above, even if the banknote is difficult to bend along the surface of the drum 312, if the tension of the tape 310 is sufficiently high when the banknote is wound around the drum 312, the composite banknote is placed on the surface of the drum 312. The bill can be wound around the drum 312 with sufficient bending. As a result, there is no gap between the tape 310 and the banknote, and the tightening of the tape 310 wound around the drum 312 is sufficiently high. Therefore, when the drum 312 is rotated in the winding direction, The tightening of the tape 310 is prevented from becoming relatively strong.

As described above, when the bill is wound around the drum 312, the tape reel 311 rotates following the rotation of the drum 312. Therefore, the tension F of the tape 310 is attached to the tape reel 311 as shown in FIG. F = T / R is determined from the limit torque T of the torque limiter 314 and the diameter R of the tape reel 311. When the diameter of the tape reel 311 is large (that is, when the tape 310 starts to be wound around the drum 312), the tension F of the tape 310 becomes relatively small. become weak.

In order to increase the tension F of the tape 310, it is conceivable to increase the limit torque T of the torque limiter 314. However, the torque limiter 314 having a large limit torque T is generally expensive. In the banknote depositing / dispensing machine 1 having a plurality of storage modules 31, if the expensive torque limiter 314 is used for all the storage modules 31, the cost will be significantly increased.

Since the deviation of banknotes is particularly noticeable in the storage module 31 for storing composite material banknotes, it may be possible to adopt an expensive torque limiter 314 only for some storage modules 31 for storing composite material banknotes. However, if such a correspondence is adopted, two types of storage modules 31 are included in one banknote depositing and dispensing machine 1. This is not preferable in terms of manufacturing management and maintenance management. Moreover, since the storage module 31 which can store a composite material banknote will be limited to the specific storage module 31, it is not preferable also at the point of the usability of the banknote depositing / withdrawing machine 1.

In addition, even if the limit torque T of the torque limiter 314 is increased, it is assumed that a larger limit torque T will be required if a new bill having a structure that is difficult to bend appears in the future.

The configuration disclosed here increases the tension of the tape 310 without increasing the limit torque T of the torque limiter 314. As described above, the tension F of the tape 310 is determined by F = T / R. If the diameter R of the tape reel 311 decreases, the tension F of the tape 310 increases. Therefore, if only the tape 310 is wound around the drum 312 in advance, and the diameter of the tape reel 311 is made smaller than the initial state shown by the one-dot chain line in FIG. 3, the tension F of the tape 310 is increased. It becomes possible to start winding the banknote around the drum 312.

On the other hand, if only the tape 310 is wound around the drum 312 in advance, the maximum capacity of the storage module 31 is reduced accordingly.

Therefore, the banknote depositing / dispensing machine 1 sets two modes as the operation mode of the storage module 31, and switches between the two operation modes for each storage module 31.

One of the two operation modes is the first mode for increasing the tension of the tape 310 as described above. In the first mode, only the tape 310 is wound around the drum 312 in advance. In the first mode, the maximum capacity of the storage module 31 decreases.

One second mode is a mode in which only the tape 310 is not wound around the drum 312. In the second mode, the tension of the tape 310 is not increased while the maximum capacity is relatively increased.

As shown in FIG. 11, light-shielding

seals

3111 and 3112 for switching between the first mode and the second mode are attached to a tape 310 made of a translucent material. The light-shielding

seals

3111 and 3112 attached to the tape 310 are for detecting the position of the tape 310 pulled out from the tape reel 311, and are arranged on the drawing path of the tape 310 between the tape reel 311 and the drum 312. It is detected by a translucent tape detection sensor (not shown). The light shielding seal includes a first light shielding seal 3111 for detecting the tape position in the first mode and a second light shielding seal 3112 for detecting the tape position in the second mode. The first light-shielding seal 3111 is attached at a position closer to the tape reel 311 than the second light-shielding seal 3112.

When operating the storage module 31 in the second mode, the controller 513 pulls out the tape 310 until it detects two second light shielding seals 3112 arranged in the longitudinal direction of the tape. Thereby, the amount of the tape 310 pulled out from the tape reel 311 is relatively reduced, and the diameter R of the tape reel 311 is increased accordingly.

On the other hand, when the storage module 31 is operated in the first mode, the control unit 513 detects the second light shielding seal 3112 and further pulls out the tape 310 until the first light shielding seal 3111 is detected. As a result, the amount of the tape 310 pulled out from the tape reel 311 increases relatively, and the diameter R of the tape reel 311 decreases accordingly.

The banknote depositing / dispensing machine 1 sets whether each of the first to eighth storage modules 31 is operated in the first mode or the second mode when the operator operates the operation unit 55. Is configured to be possible. For example, the storage module 31 that stores composite material bills may be operated in the first mode, and the storage module 31 that does not store composite material bills may be operated in the second mode. By doing so, in the storage module 31 for storing the composite material banknote, in which the banknote is likely to be shifted, the tension F of the tape 310 when the banknote is wound around the drum 312 increases, so that the banknote can be reliably and stably transferred to the drum 312. It becomes possible to wrap around. As a result, when the drum 312 is rotated in the winding direction, the tightening of the tape 310 on the inner side in the radial direction is strengthened, and the tightening of the tape 310 in the intermediate portion is relatively weakened so that the banknote is displaced. It becomes possible to prevent. On the other hand, in the storage module 31 that does not store composite banknotes, the banknotes are not likely to be displaced from each other, so that it is not necessary to increase the tension of the tape 310. Therefore, by operating the storage module 31 in the second mode, it is possible to avoid the maximum capacity of the storage module 31 from being reduced while stably storing banknotes.

Note that, as described above, the banknote depositing and dispensing machine 1 is configured such that the operator sets whether to operate each of the first to eighth storage modules 31 in the first mode or the second mode. Alternatively, if the banknotes to be stored in the first to eighth storage modules 31 are determined, the storage module 31 for storing composite material banknotes is automatically operated in the first mode and stored without storing the composite material banknotes. The module 31 may be operated in the second mode.

Also, increasing the tension of the tape 310 is advantageous in preventing the tape 310 from being cut. That is, the tape 310 pulled out from the tape reel 311 passes through the tape regulation guide 313 to the drum 312 as shown in FIG. 3, but if the tension of the tape 310 is high, flapping in the middle of the tape 310 is suppressed. The When the tape 310 flutters, the tape 310 may interfere with the tape regulation guide 313, and the tape 310 may be cut. By increasing the tension of the tape 310 and suppressing the fluttering of the tape 310, It is possible to prevent the tape 310 from being cut. Further, increasing the tension F of the tape 310 can prevent the tape 310 from being tightened excessively when the drum 312 is rotated in the winding direction, and is effective in preventing damage to the tape 310 due to this. .

(Configuration 4: Control configuration for regulating storage of composite material bills in storage module)
As described above, the deviation of the bills in the storage module 31 is caused by the drum 312 rotating in the winding direction in a state where the outer diameter of the drum 312 is large, and many composite material bills are wound around the drum 312. If so, the tape 310 may be weakly tightened in the intermediate portion in the radial direction. Therefore, it is conceivable to prevent the outer diameter of the drum 312 from being increased by decreasing the maximum capacity of the storage module 31 when the number of composite material bills stored in the storage module 31 is increased.

However, this configuration is not a preferable measure because the capacity of the banknote depositing / dispensing machine 1 is deteriorated because the storage amount of the storage module 31 is reduced. Since banknotes that cannot be stored in the storage module 31 are discharged to the withdrawal port 231 as reject banknotes, the reject banknotes increase when the maximum capacity of the storage module 31 decreases. This makes the usability of the banknote depositing / dispensing machine 1 worse.

Here, as shown in FIG. 5, the difficulty of bending with respect to the surface of the drum 312 varies depending on the front and back sides and the direction of the composite material banknotes stored in the storage module 31. This is also a cause that the tightening of the tape 310 is weakened and the banknote is shifted. However, the inventors of the present application have studied, and the occurrence of the banknote shift is simply the number of composite material banknotes stored or the composite It turned out that not only the front and back and the direction of the material bill but also various other factors were combined.

The configuration 4 disclosed here does not store only the composite material banknotes that are highly likely to cause the deviation of the banknotes in the storage module 31 while considering combinations of various factors, and other banknotes are stored in the storage module. By storing in 31, the storage amount of the storage module 31 is prevented from decreasing. Hereinafter, various factors that cause the deviation of banknotes will be described in order, and then control for restricting the storage of composite material banknotes in the storage module 31 performed in the banknote depositing and dispensing machine 1 will be described.

<Radial position of composite banknotes in the drum on which banknotes are wound>
As shown in FIG. 6, when the composite material banknote is wound around the drum 312, the tape 310 and the banknote wound around the drum 312 may have a truncated cone shape. Here, even if the number of the composite material banknotes wound around the drum 312 is the same and the tape 310 and the banknotes wound around the drum 312 are in the shape of a truncated cone, The present inventor has realized that there are cases where it is difficult to occur.

That is, the left figure of FIG. 12 illustrates the case where many composite material banknotes are wound around the inside of the drum 312 in the radial direction, and normal banknotes that are not composite material banknotes are wound around the outside in the radial direction. is doing. In this state, since the banknotes wound around the drum 312 are inclined as a whole, if the tightening of the tape 310 is weakened, the banknotes are easily displaced. On the other hand, in the right diagram of FIG. 12, many normal banknotes that are not composite material banknotes are wound on the inner side in the radial direction of the drum 312, and many composite material banknotes are wound on the outer side in the radial direction of the drum 312. Shows the case. In this state, the outer peripheral surface of the drum 312 is inclined, and the tape 310 and the banknote wound around the drum 312 have a truncated cone shape, but the banknote is not inclined in the radial intermediate portion. Therefore, even if the tape 310 is weakened at the intermediate portion of the drum 312, the banknote is not easily displaced. In this way, not only the number of composite material banknotes wound around the drum 312 is large and small, but also the radial position of the composite material banknotes wound around the drum 312 affects the occurrence of banknote misalignment.

Accordingly, when the composite material bill is positioned on the inner side in the radial direction rather than limiting the maximum capacity of the storage module 31 based only on the number of composite material bills stored in the storage module 31, the composite material bill If the storage module 31 is not stored, it is possible to increase the maximum capacity of the storage module 31 while suppressing the occurrence of bill deviation.

<Relative position of unevenness of composite bill and tape>
As shown in FIG. 5, the difficulty of bending with respect to the surface of the drum 312 varies depending on the front and back sides and the direction of the composite bill. When the composite bill is in the A direction and the B direction, it is difficult to bend along the surface of the drum 312, and therefore, generally, a gap is easily generated between the composite bill and the tape 310 when wound around the drum 312. However, depending on the relative position of the unevenness of the composite material bill and the tape 310, the composite material bill can be sufficiently bent along the surface of the drum 312, and there is a gap between the composite material bill and the tape 310. The inventor of the present application has noticed that it is less likely to occur. That is, when the unevenness of the composite material banknote and the tape 310 are short, the unevenness is difficult to bend, but the banknote can be pressed by the tension of the tape 310, and the gap between the composite material banknote and the tape 310 can be reduced. Is less likely to occur.

FIG. 13 illustrates the relative position between the unevenness of the composite bill and the tape 310. In the banknote depositing / dispensing machine 1, in order to allow a difference in size depending on currency and denomination, the position of the banknote is shifted (that is, centered, left justified, and right justified) in a direction orthogonal to the transport direction. It is configured as follows.

Even if the composite material banknotes are conveyed in the same direction A, if the center of the composite banknotes are left-justified or left-aligned, the unevenness of the composite material banknotes and the tape 310 are close, so the unevenness is bent by the tape 310. And the tape 310 are less likely to cause a gap. Therefore, even if the composite material banknote is stored in the storage module 31, the banknote is unlikely to shift. On the other hand, when the composite material bill conveyed in the A direction is right-justified, since the distance between the unevenness of the composite material bill and the tape 310 is long, the composite material bill is difficult to bend. A gap is easily generated between the two. Therefore, when the composite material banknote is stored in the storage module 31, it may be a factor of banknote misalignment. Similarly, even when the composite material bill conveyed in the B direction is left-justified, the distance between the unevenness of the composite material bill and the tape 310 is long, so that the composite material bill is difficult to bend and the composite material bill Between the tape 310 and the tape 310. In this case as well, when stored in the storage module 31, it may be a factor of banknote misalignment.

Here, when the composite material banknote is simply in the A direction or in the B direction, if the banknote is prohibited from being stored in the storage module 31, a large number of banknotes are not stored in the storage module 31. . The number of reject banknotes increases, and the usability of the banknote depositing / dispensing machine 1 becomes worse. As described above, storage of banknotes in the storage module 31 is prohibited only when the composite material banknote is in the A direction and right-justified, and only when the composite material banknote is in the B direction and left-justified. For example, it is possible to prevent the tape 310 and the banknote wound around the drum 312 from being in the shape of a truncated cone as shown in FIG. 6 while preventing an increase in reject banknotes. As a result, it is possible to effectively prevent the banknotes from shifting and to avoid the deterioration of the usability of the banknote depositing and dispensing machine 1.

<Storage control based on a combination of various factors>
The control unit 513 of the banknote depositing / dispensing machine 1 determines whether or not the composite material banknote can be stored in the storage module 31 based on the combination of the various factors described above. By doing so, it is possible to prevent the banknotes wound around the drum 312 from shifting while storing as many composite material banknotes as possible in the storage module 31. Specifically, the control unit 513 determines whether or not the composite material banknote can be stored based on the combination shown in FIG. When the number of storage modules 31 is less than or equal to a predetermined number (for example, 100) and the A-direction composite material banknote is right-justified, and the number of storage modules 31 is less than or equal to the predetermined number and the B-direction When the composite material bill is left-justified, the composite material bill is not stored in the storage module 31. The composite material bill is paid out to the withdrawal port 213 as a reject bill.

When the storage amount of the storage module 31 is small, the composite bill is positioned inside the drum 312 in the radial direction when it is wound around the drum 312 (see the left figure in FIG. 12). Further, when the composite material banknote in the A direction is right-justified or when the composite material banknote in the B direction is left-justified, the unevenness of the composite material banknote is difficult to bend, and a gap is easily generated between the tape 310 and the banknote ( (See FIG. 13). Therefore, the storage of the composite material bill is prohibited only when these plural factors are combined.

By doing so, the tape 310 and the banknote wound around the drum 312 are prevented from becoming a truncated cone in the storage module 31 while reducing the banknotes to be paid out to the withdrawal port 213 as reject banknotes, and banknotes It is possible to prevent the deviation from occurring.

Note that the composite material banknotes paid out as reject banknotes due to the above factors are stored in the storage module 31 by adjusting the direction, direction, and position of the composite banknotes when they are re-inserted into the deposit port 211. Is possible.

(Banknote depositing and dispensing machine with stack-type storage unit)
The technique disclosed here is not limited to being applied to the banknote depositing / dispensing machine 1 having a winding type storage unit. The present invention can also be applied to a banknote depositing / dispensing machine having a stack type storage unit.

FIG. 15 illustrates a banknote depositing / dispensing machine 10 having a stack type storage unit. This banknote depositing / dispensing machine 10 has a plurality of (first to fourth in the illustrated example) stack type storage cassettes 33 _-1 to 33 _-4 . The stack-type storage cassette 33 has a stage 331 that can move in the vertical direction. On the stage 331, banknotes are stacked in the vertical direction. These stack type storage cassettes 33 are configured to be able to pay out banknotes stored therein. Since the configuration of the stack-type storage cassette 33 is known, a detailed description of the configuration is omitted.

Also in this stack type storage cassette 33, it is not preferable to repeatedly store and pay out bills in a state close to full. That is, at the time of paying out, the stacked banknotes are pressed in the stacking direction, and the topmost one is drawn out, but in a state close to the full amount, the banknotes are piled up high, so the pressing becomes unstable. Because. Further, the banknotes cannot be fed out stably. In particular, when composite material banknotes are stacked, since the thickness of banknotes is not constant, the banknotes stacked on the stage 331 may be tilted, increasing the instability described above. Further, when the stack-type storage cassette 33 is almost full, the storage of banknotes can be unstable.

Therefore, the configuration 1 is also adopted in the banknote depositing and dispensing machine 10 including the stack type storage cassette 33. That is, the control unit 513 allows the storage amount of the storage cassette (for example, the first storage cassette 33 ₋₁ ) to not repeat the storing and feeding of the bills when the storage amount of the storage cassette 33 is almost full. if reaching the first storage amount set in advance, until it reaches the second amount of storage that is set in advance, to prohibit the storing bills to the first storage cassette 33 _-1. To feed the banknotes from the first storage module 33 _-1 permits. The first storage cassette 33 _-1 is set to pay-out dedicated storage cassette.

At this time, the control unit 513, the second storage cassette 33 _-2 accommodating the same bills in the first storage cassette 33 _-1 is set in the storage dedicated storage cassette. That is, the second storage cassette 33 _-2, while the banknote storage is permitted, feeding the paper money is prohibited.

By the bill is fed out from the first storage cassette 33 _-1, when the storage amount reaches the second amount of storage, the control unit 513, a first storage cassette 33 _-1, from the supply dedicated storage cassette, Switch to a dedicated storage cassette. The control unit 513 also the second storage cassette 33 _-2 from the storage dedicated storage cassette, switches the feeding dedicated storage cassette. First storage cassette 33 _-1 is allowed banknotes accommodated, feeding the paper money is prohibited. Second storage cassette 33 _-2 allowed feeding banknotes, banknote storage is inhibited. In this way, even in the banknote depositing / dispensing machine 10 including the stack type storage cassette 33, it is possible to prevent the banknotes from being repeatedly stored and delivered while the storage cassette 33 is almost full.

As described above, before the first storage cassette 33 _-1 set in the exclusive feeding reaches the second amount of storage, the second storage cassette 33 set in the storage specific _-2, first storage amount to when it reaches, in its timing, to the first storage cassette 33 _-1 housing dedicated storage cassette may switch the second storage cassette 33 _-1 to feeding dedicated storage cassette.

Further, each of the plurality of storage cassettes 33 is configured to permit both storage and withdrawal of banknotes, and when any one of the storage cassettes 33 reaches the first storage amount, While storage of banknotes is prohibited until the second storage amount is reached and banknote feeding is permitted, the other storage cassette 33 may permit both storage and delivery of banknotes.

The banknote depositing / dispensing machine 10 provided with the stack type storage cassette 33 may also adopt the configuration 4 described above. In the stack-type storage cassette 33, when many composite material banknotes are included below the stacked banknotes, the stacked banknotes tend to be inclined and unstable. Further, in the stacked banknotes, when the unevenness of the composite material is stacked at the same position, the inclination of the stacked banknotes is further increased. Therefore, also in the banknote depositing / dispensing machine 10 provided with the stack-type storage cassette 33, the control unit 513 performs the composite material banknote according to the number of stored storage cassettes 33, the front and back and direction of the composite material banknote, and the position thereof. May not be stored in the storage cassette 33.

In addition, although the storage cassette 33 which stacks and stores a banknote in the up-down direction is shown here, it is good also as a storage cassette which stores a banknote in a horizontal direction.

The technology disclosed here is not necessarily applied to the banknote deposit and withdrawal machine described above. The present invention can be widely applied to a banknote processing apparatus that stores a banknote and includes a winding-type storage unit and / or a stack-type storage unit, and stores and feeds out banknotes.

In addition, the object to be stored and delivered to the storage unit is not limited to banknotes, but is general paper sheets including securities such as gift certificates, checks and gift certificates, and the technology disclosed here is a paper sheet processing apparatus. It is applicable to. *
