Description

  The present invention relates to an improvement of a banknote handling apparatus equipped in a banknote handling apparatus such as various vending machines, depositing / withdrawing apparatuses, and money changers having a function of depositing banknotes. The present invention relates to a technique that can improve the efficiency of replenishment of change banknotes at the start of work without complicating the apparatus configuration in a reflux-type banknote processing apparatus including a plurality of storage units.

Banknote processing devices equipped with a deposit function that accepts inserted banknotes and a withdrawal function that dispenses banknotes as change or withdrawal are equipped in various vending machines, deposit and withdrawal devices, money changers, etc. The apparatus is equipped with a banknote storage unit for storing banknotes prepared at the start of business or banknotes inserted during operation in denominations.
In addition to banknotes stored for change in advance at the start of work, the banknote storage unit temporarily stores banknotes inserted by the user during operation of the device, while externally used to change these banknotes as change. There are a reflux-type banknote storage unit provided with a function of discharging to a banknote and a banknote storage unit for recovery (collection cassette) that recovers all banknotes in the banknote processing apparatus at the end of work.

When the reflux-type banknote storage unit is in an empty state at the start of work or the like, it is necessary to replenish banknotes for change. In Japan, it is common practice to replenish 1,000 yen bills, which are frequently used as change for high-value banknotes such as 5,000 yen and 10,000 yen bills, into the reflux-type banknote storage section for thousand yen bills at the start of business. In this replenishment operation, a replenishment cassette containing replenishment banknotes is set in the main body of the apparatus, and a feeding mechanism provided in the replenishment cassette is driven to replenish a thousand yen bill into a reflux-type banknote storage unit for a thousand yen bill. It is common.
The collection cassette is provided in the apparatus separately from the reflux-type banknote storage unit provided for each denomination, and collects all denominations from each reflux-type banknote storage unit.
As described above, in the reflux-type banknote processing apparatus, the recovery cassette and the replenishment cassette are used together, but conventionally, the type in which the recovery cassette and the replenishment cassette are always mounted in the apparatus main body has been mainstream. However, this type has a drawback in that the apparatus configuration is enlarged by this space because a replenishment cassette that is not used during operation is always provided.
In order to cope with this problem, a type in which the functions of a collection cassette and a replenishment cassette are combined in one cassette has been developed and implemented (Patent Document 1). However, this type has a configuration in which the collection function and the replenishment function (feed-out function) are integrated in one cassette, which causes problems such as a complicated structure and an increase in cost.

By switching and driving the respective rollers, belts, and gates 11 under the control of the control means 80, the above transport functions can be realized at a predetermined timing.

The first reflux-type banknote storage unit 10 is dedicated to, for example, a 5,000-yen banknote, and is a reflux function for sending 5,000-yen banknotes once received via the transport path 5 to the transport path 5 one by one when collecting banknotes. have.
The second reflux-type banknote storage unit 12 is for banknotes that are frequently used as change, for example, thousand-yen banknotes, and sends the thousand-yen banknotes once received via the transport path 5 to the transport path 5 one by one. It has a function. When the change is paid out, the thousand yen bills sent one by one to the conveyance path 5 are sequentially wound around the drum and overlapped to be conveyed to the deposit / withdrawal unit 3 as a bill bundle. Further, when collecting banknotes, the banknotes sent out one by one from the reflux-type banknote storage units 10 and 12 to the transport path 5 are sequentially wound around the drum and overlapped to be transported and stored in the recovery cassette 30 as a banknote bundle.
The first and second reflux-type banknote storage units 10 and 12 can store about 100 banknotes.
The replenishment cassette 20 and the recovery cassette 30 have substantially the same external shape so that they can be individually mounted in the cassette mounting portion 15.
The replenishment cassette 20 replenishes a replenishment banknote storage unit 21 that stores a large number (for example, 800 or more) of replenishment banknotes, and a banknote P1 that is stored in the replenishment banknote storage unit 21 when it is mounted on the cassette mounting unit 15. It has a feeding mechanism 23 that feeds out of the cassette (replenishment banknote determination unit 40), and a reject box 24 (accommodating amount of about 20 sheets) that stores the replenishment banknotes that have been rejected and returned by the replenishment banknote determination unit 40.

As shown in FIG. 2, the replenishment banknote storage unit 21 includes a backup plate 22a that is constantly biased upward, and a replenishment banknote P1 is stacked on the backup plate 22a. The feeding mechanism 23 contacts the uppermost portion of the banknote bundle on the backup plate 22a and separates the banknotes taken out one by one from the takeout roller 23a, and separates the banknotes taken out by the takeout roller toward the replenishing banknote determination unit 40. A separation roller pair 23b for feeding, a feeding roller 23c capable of forward / reverse rotation, a switching gate 23d, and the like are included. The rollers 23a and 23b are driven by motors M1 and M2 mounted in the replenishment cassette 20, and the feeding roller 23c is driven by the driving force of the bill processing apparatus main body. The switching gate 23d is driven by a solenoid (not shown). On the apparatus main body side, a switching gate 11a that rotates to feed the replenishment banknotes fed from the feeding mechanism 23 to the replenishment banknote determination unit 40 or to feed the banknotes in the replenishment banknote determination unit 40 to the transport path 5 is arranged. The switching gate 11a is driven by a solenoid (not shown). The sensor S1 is an end sensor (replenishment banknote detection means) that detects the presence or absence of the replenishment banknote P1 on the backup plate 22a, the sensor S2 is a reject box full detection sensor, and the sensor S3 is a feeding detection sensor. .
When it is detected that the replenishment cassette 20 containing the replenishment banknotes is mounted on the cassette mounting unit 15, the feeding mechanism 23 in this state causes the feeding mechanism 23 to refill the replenishment banknotes one by one. By feeding out and driving the switching gate 11a, it is fed to the replenishing banknote determination unit 40. When it is determined that the banknote is a normal banknote by detection by the sensor 44, the switching gate 11a is switched and conveyed back to the transport path 5 by switching back. The switching gate 11a and the feeding roller 23c are driven so as to be fed into the reflux-type banknote storage units 10 and 12 and fed into the reject box 24 when the banknotes are not regular banknotes.

The recovery cassette 30 whose internal configuration is shown in FIG. 1A includes a recovery mechanism 31 that stores banknotes that have been transported via the transport path 5 when mounted on the cassette mounting section 15, and a recovered banknote storage section. 32. The collection mechanism 31 includes a roller group 31a that feeds the banknotes sent from the transport path 5 to the collection banknote storage unit 32, and a motor (not shown) that drives the roller group 31a. The collected banknote storage unit 32 is movable up and down through a backup plate 32a that can be moved up and down and always biased upward, a fork 32b as a fixing member in contact with the upper surface of the banknote bundle on the backup plate, and a notch provided in the fork. And a pressurizing member 32c that can be raised and lowered to push down the banknote on the upper surface. The banknotes sent by the roller group 31a constituting the collection mechanism 31 are temporarily stopped on the fork 32b. In this state, the pressurizing member 32c descends and presses the upper surface of the banknote, so that the banknote is deformed while the banknote is deformed. It is transferred onto the backup plate via the opening.
The cassette mounting portion 15 is a space provided at the bottom of the apparatus housing, and a connector portion 16 connected to terminals 20A and 30A provided on the back wall of the replenishment cassette 20 and the collection cassette 30 on the inner wall thereof. I have. By completely attaching either the replenishment cassette 20 or the recovery cassette 30 to the connector section 16, the terminal 20A or 30A and the connector section 16 are in an electrically connected state, and the drive section in each cassette is connected to the drive section. On the other hand, power is supplied and signals are exchanged with the control means. Further, the control means can determine which of the replenishment cassette 20 and the recovery cassette 30 is connected based on the difference in electrical signal obtained by connecting the connector portion 16 and each terminal. Alternatively, another cassette for discrimination (a limit switch or a photo sensor) may be provided so that the cassette can be discriminated.

Further, as will be described later, a lock mechanism and a cassette push-out mechanism for mechanically locking each cassette mounted are provided in the vicinity of the cassette mounting portion 15, and when the lock state by the lock mechanism is released, The cassette push-out mechanism operates in conjunction with each other, and each cassette is pushed out of the cassette mounting portion. In this example, the control means performs the replenishment operation when the banknote in the replenishment cassette ends or when the reflux-type banknote storage units 10 and 12 are full (or when the required number of sheets is reached). Stop and push out the refill cassette automatically.
The replenishment banknote determination unit 40, in a state where the replenishment cassette 20 is mounted in the cassette mounting unit 15, the switchback unit 41 that reversely transports the banknotes that are fed one by one from the replenishment cassette, and then switches back. A sensor 44 for determining double feeding of banknotes sent to the unit 41 and denomination is provided. The switchback unit 41 includes a switchback drive mechanism 42 such as a roller and a belt driven by a motor (not shown), and a switching gate 11a so as to convey the replenished banknotes in both forward and reverse directions under the control of the control means. It is configured. When the switching gate 11a is directed in the direction of guiding to the switchback portion 41, the bill is introduced into the switchback portion by driving the feeding mechanism 23 and feeding out the bill.

The direction of guiding the switching gate 11a to the transport path 5 when the sensor 44 (photo sensor or the like) detects the banknote received in the switchback unit 41 and the control means determines that the banknote is a regular banknote based on the detection result. The switchback unit 41 sends the bills toward the transport path 5. Thereafter, the transport mechanism 6 feeds either of the reflux-type banknote storage units 10 and 12 according to the denomination (thick line transport path in FIG. 1A).
When it is determined that the banknote received by the switchback unit 41 is a banknote to be rejected, the switchback drive mechanism 42 is driven to replenish the switch gate 11a in the same direction as when the replenishment banknote is fed. Return to cassette 20. At this time, the reject banknote is accommodated in the reject box 24 by reversing the forward / reverse rotation roller 23c while turning the direction of the switching gate 23d toward the reject box 24 (thick line conveyance path in FIG. 1B).
Note that the switchback-type replenishment banknote determination unit 40 is not essential and can be omitted according to the needs of the user. When the replenishment banknote determination unit 40 is not provided, the banknotes fed out from the replenishment cassette are sent out to the transport path 5. In this case, a sensor for determining the double feeding and denomination of banknotes is provided in the transport path, and when it is necessary to reject, it is transferred to a reject box, and when it is normal, it is sorted into each reflux-type banknote storage unit 10, 12. Transport.

Next, the configuration of the replenishment cassette locking mechanism and the operation procedure will be described with reference to FIGS. 3 (a), 3 (b) and 3 (c) and FIGS. 4 (a), 4 (b) and 4 (c).
As shown in FIG. 3B, the replenishment cassette locking mechanism 50 according to this example includes a cassette-side component provided on the front side in the thickness direction avoiding the replenishment banknote storage portion 21 and the feeding mechanism 23 of the replenishment cassette, It is comprised from the apparatus main body side components provided in the banknote processing apparatus 1 side.
That is, the cassette side parts are provided in the intermediate portion by the lock release solenoid 51 provided in the replenishment cassette, the first link piece 52 supported at one end by the plunger 51a of the lock release solenoid 51, and the replenishment cassette. The second link piece 54, which is pivotally supported by the shaft support portion 54a and is pivotally supported by the tip end portion of the first link piece 52, and the solenoid plunger 51a, always protrudes. A spring (not shown) that biases in the direction and an opening 56 formed at a position where the other end 54c of the second link piece 54 faces. As shown in FIG. 4A, when the solenoid 51 is OFF, the plunger 51a protrudes by the spring, so the second link piece 54 maintains a horizontal posture. When the solenoid is turned on and the plunger 51a is retracted as shown in (b), the other end 54c of the second link piece 54 protrudes outward from the opening 56.

Next, the apparatus main body side component is always in the locking member 60 pivotally supported by the apparatus main body so that the base end portion 60a is pivotable in the vertical direction, and the direction in which the distal end portion 60b of the locking member 60 descends (locking direction). A spring (not shown) for biasing and an elastic member (cassette pushing mechanism) (not shown) for constantly biasing the replenishment cassette in the direction (left side of the drawing) to be detached from the cassette mounting portion 15 are provided. A lock piece 61 protrudes from an intermediate position of the lock member 60, and a roller 62 is rotatably supported on the lock piece 61. When the replenishment cassette 20 is not mounted in the cassette mounting portion 15, the lock member 60 is in a lowered state.
Since the other end 54c of the second link piece 54 is lowered when the solenoid 51 is in the OFF state as shown in FIG. 4A, there is room for the lock piece 61 to enter the opening 56. When the replenishment cassette 20 outside the apparatus is mounted in the cassette mounting portion 15 with the solenoid 51 turned off, the lock piece 61 in the lowered state enters the opening 56 in the process of mounting against the elastic member. 4 (a) is locked.
When the lock member 60 is lowered, the claw portion 61a provided on the lock piece 61 is locked (locked) to the inner peripheral edge of the opening 56, so that the replenishment cassette 20 cannot be pulled out in the removal direction (left side of the drawing). .

Next, when the solenoid 51 is energized and turned on, the plunger 51 a retracts and lowers the first link piece 52, so that the other end 54 c of the second link piece 54 rises toward the opening 56. At this time, since the other end 54c pushes up the roller 62 supported by the lock piece 61, it is separated from the inner peripheral edge of the claw portion 61a and the opening 56 as shown in FIG. 4B, and the lock is released. When the lock is released, the force for pushing out the replenishment cassette by the elastic member becomes effective, and the replenishment cassette is pushed out of the cassette mounting portion 15.
Next, reference numeral 70 in FIG. 4 denotes a rotary lock provided on the apparatus main body side for unlocking. The rotary lock extends from a cylinder lock 71 and an operating piece 72 of the cylinder lock. And a connecting piece 73 to be joined. When the unlocking solenoid 51 on the replenishing cassette side performs the unlocking operation, the unlocking can be facilitated by operating the locking member 60 in the locking direction by the rotary lock 70.
That is, since the cylinder lock 71 is in the OFF state in the locked state of FIG. 4A, a spring (not shown) lowers the distal end portion 60b of the lock member 60. Next, when the cylinder lock 71 is rotated as shown in (b), the connecting piece 73 pulls up the lock member 60, so that the lock piece 61 is detached from the opening 56. As a result, the replenishment cassette 20 is pushed out by the elastic member as shown in FIG.

In the present invention, when the replenishment cassette is mounted in the cassette mounting portion and the replenishment banknote is fed out from the replenishment cassette, the control unit 80 has the sensor S1 (replenishment banknote detection unit) that the banknote in the replenishment cassette is at the end. Is detected, or when the banknotes stored in the reflux-type banknote storage units 10 and 12 are full (or when the specified number is reached), the replenishment operation is stopped and the lock mechanism 60 is operated to lock the lock member 60. Release and automatically push out the refill cassette.
Even when the recovery cassette 30 is mounted on the cassette mounting portion 15, the lock member 60 is actuated to engage with an opening provided on the recovery cassette 30 side (corresponding to the opening 56 of the replenishment cassette) to lock the recovery cassette. However, in order to release the lock and take out the collection cassette, the rotary lock 70 on the apparatus main body side may be operated.
The operation of releasing the lock mechanism by adopting a rotary solenoid instead of the rotary lock can be performed by operating an operation key arranged on the operation board.
In addition, when the collection operation is disclosed in a state where the collection cassette 30 is mounted on the cassette mounting unit 15, the control unit 80 collects the banknotes stored in the reflux-type banknote storage units 10 and 12 via the transport path. Control is performed so that the cassette 30 is conveyed.

Next, a procedure for automatically replenishing change bills (thousand-yen bills) using a replenishment cassette at the start of work will be described with reference to FIG.
First, when a cassette is mounted in the cassette mounting unit 15 after power is turned on (S2, Yes), it is determined which cassette is set (S3). This determination is performed by the control means based on a signal obtained based on the connection between the terminals 20A and 30A provided in each cassette and the connector 16 on the apparatus main body side. As a result of the determination, when the cassette is a collection cassette (S3 No), the operation mode is shifted to a normal operation mode, and when the cassette is a replenishment cassette (S3 Yes), the operation proceeds to a replenishment cassette feeding operation. In the replenishment cassette feeding operation, the feeding mechanism 23 is driven and the switchback drive mechanism 42 is further driven with the switching gate 23d facing the outside of the cassette and the switching gate 11a facing the replenishing bill determination unit 40 ( S4 to S7). The replenishment banknote determination unit 40 checks the presence or absence of the multifeed and the denomination of the banknote by the sensor 44. If there is a multifeed and the denomination is different, each banknote is fed back to the reject box 24. At this time, the switching gate 23d is switched to the replenishment cassette 20 side, and the switchback drive mechanism 42 is reversed (S8 to 12).

When there is no double feed and the denomination is regular (both S9 and 11 are YES), the switching gate 11a is switched to the transport path 5 side, and the switchback drive mechanism 42 and the transport mechanism 6 are driven to replenish banknotes. It sorts and conveys to each reflux type banknote accommodating part 10 and 12 (S13).
After that, when the replenishment operation is repeated and the replenishment cassette 20 becomes empty, or when the reflux-type banknote storage unit 12 for a thousand yen banknote reaches a specified number (full or required number of reserves). Releases the auxiliary mechanism 20 from the cassette mounting portion 15 by releasing the lock mechanism and operating the cassette push-out mechanism.
The feature of the banknote handling machine 1 according to the present invention is that when the banknotes are replenished, the collection cassette 30 already mounted on the cassette mounting section 15 is once removed and the replenishment cassette 20 can be mounted.
After the banknote replenishment using the replenishment cassette is completed, the replenishment cassette is removed and the collection cassette 30 is set in the cassette mounting unit 15 to perform normal operation. In this way, the replenishment cassette is set and used in the cassette mounting portion only at the time of replenishment, and after replenishment, it is possible to use one replenishment cassette in common for a plurality of banknote processing apparatuses 1 by removing and setting the collection cassette. It becomes. For this reason, it is not necessary to increase the size of the banknote handling apparatus, and the cost can be reduced.

This will be described in detail. For example, when the number of sheets stored in the collection cassette 30 and the replenishment cassette 20 is 800 sheets, and the number of sheets stored in each of the reflux-type banknote storage units 10 and 12 is 100 sheets, About 50 sheets are sufficient as a reserve to be stored in the second reflux-type banknote storage unit 12 for storing the thousand yen bill at the start of work. Therefore, 800 thousand yen bills that can be stored in the replenishment cassette 20 correspond to 16 replenishment operations. Therefore, when managing a plurality of banknote processing apparatuses 1, it is not necessary to prepare one replenishment cassette for each banknote processing apparatus, and banknote replenishment work for a plurality of banknote processing apparatuses with one replenishment cassette. Can be implemented sequentially. That is, it is only necessary to purchase and possess a replenishment cassette for each of a plurality of banknote processing apparatuses, and the purchase cost can be reduced. A replenishment cassette having a feeding mechanism with a complicated structure is more expensive than a recovery cassette having a structure for simply storing banknotes, so that the merit of reducing the number of replenishment cassettes purchased is great.
In addition, depending on how the banknote processing device is operated, a case that does not require a change banknote replenishment operation at the start of work (when a thousand-yen bill is accumulated in the reflux-type banknote storage part to some extent without replenishing banknotes as reserve money) In this case, it is not necessary to purchase a replenishment cassette. That is, it is possible to determine whether or not it is necessary to purchase a replenishment cassette according to the type of operation while considering the cost.

In addition, before replenishing banknotes from the replenishment cassette to the reflux-type banknote storage unit, the presence / absence of double feeding from the replenishment cassette, the denomination of the denomination, Is housed in a reject box in the refill cassette. For this reason, it can prevent that the banknote which is not suitable as a change is accommodated in a reflux type | formula banknote accommodating part.
When the collection cassette 30 is removed from the cassette mounting portion and the replenishment cassette 20 is mounted, the replenishment cassette is automatically locked so as not to be removed from the cassette mounting portion 15, and the replenishment operation is automatically started. When the banknote in the replenishment cassette is empty or the recirculation banknote storage part for change is full (or when the required number is reached), the replenishment operation is stopped, the lock is automatically released, and the replenishment cassette is It is pushed out from the cassette mounting part.
During the replenishment operation, it is displayed on the display unit of the banknote handling apparatus that replenishment is in progress.
At the end of work, the banknotes stored in the reflux-type banknote storage units 10 and 12 are sequentially transferred into the recovery cassette 30 to complete the recovery.
