[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coin processing device incorporated in a vending machine, a money changer, a parking lot device, etc. (hereinafter referred to as a transaction device), and particularly to a coin handling device capable of increasing the number of coins to be accommodated and providing a stable coin The present invention relates to a coin processing device capable of discharging coins. The present invention also relates to a coin jam removing method for a coin processing device, which automatically removes and recovers a coin jam that occurs when a coin is collected in the coin processing device.

[0002]

2. Description of the Related Art A coin processing device stores a predetermined prepared coin in a circulating change section at the start of business and collects and manages the coin in a collecting box at an appropriate time. In such a coin processing device, a type having a sorting gate and a chute as a collection processing mechanism, and, for example, Japanese Patent Application Laid-Open No.
There is a miniaturized form using a shutter as disclosed in Japanese Patent Laid-Open No. 001-43425. The type using a shutter is smaller than the type having a sorting gate and a chute, omitting the sorting gate and the collecting unit of the discharging mechanism of the circulating change section.

In the former type of collecting process, the collecting mechanism of the circulating change section operates the distributing gate to discharge the collected money to a collecting box provided below the transaction device using the collecting section such as a chute. On the other hand, in the latter type of recovery processing, the recovered coins are discharged to the conveyor belt and are conveyed to the side opposite to the side where the change coins are discharged for recovery.

[0004]

However, in recent years, as the operation of a transaction apparatus in which a coin processing apparatus is used, the number of coins stored in the circulation change unit is increased in order to extend the operation time, and a large amount of coins are collected. Has become. Therefore, a large amount of coins from the discharging mechanism are continuously discharged onto the conveyor belt during recovery, and the conveyor belt temporarily stops due to the state of coins, or the rotation speed of the motor that drives the conveyor belt is significantly reduced. There was a problem that it may happen (hereinafter referred to as "lock").

Further, in the case where the conveyor belt is locked and the release from the circulating change section is continued, the locked state is promoted, and in some cases, it deviates from the range in which the person in charge of operating the transaction apparatus can perform maintenance work. Therefore, the maintenance staff of the manufacturer may be in charge of the recovery work. The present invention has solved the above-mentioned problems, and an object of the present invention is to provide a small-sized coin processing device capable of smoothly collecting coins even when the number of stored coins is large. Also,

That is, when the detection sensor 224 that detects the coin transport state of the transport belt 204 and the lock state of the transport belt 204 is detected by the detection sensor 224, the coin discharge from the coin stock 18 is suppressed and the transport belt is stopped. Lock release means 38 for removing the locked state at 204, and when the lock release operation by the lock release means 38 causes the detection sensor 224 to detect that the locked state at the conveyor belt 204 is released. Is characterized by restarting the coin discharge from the coin stock 18.

In the apparatus constructed as described above, when the detection sensor 224 detects a locked state that is likely to occur when a large amount of coins stored in the coin stock 18 is detected, the coin release 18 is performed by the unlocking means 38. Since the discharge of coins from the coin is suppressed, further accumulation of coins in the locked state can be prevented. Also, the unlocking means 3
Since the unlocking operation is performed by 8, the lock releasing means 38 releases most of the locked state. Therefore,
The failure rate that maintenance personnel have to deal with is reduced.

[0008] Preferably, the unlocking operation by the unlocking means 38 may be configured to rotate the conveyor belt 204 forward or backward by a predetermined distance. In the device configured as described above, since the coin release from the coin stock 18 is suppressed by the lock releasing means 38, the target coin for the unlocking operation is the conveyor belt 2 when the locked state is detected.
It is possible to prevent deterioration of the drive motor that rotates the conveyor belt 204 forward or backward by a predetermined distance while being limited to the coins accumulated in 04. Further, since the lock releasing operation is performed by rotating the conveyor belt 204 in the normal direction or the reverse direction, by determining the optimum feeding mode of the conveyor belt 204, it contributes to downsizing of the coin processing device.

Further, the coin processing device is provided with the conveyor belt 2.

08, and the detection sensor 224 detects the state where the conveyance of the conveyance belt 204 is stopped to detect the locked state, a large amount of coins to be collected are discharged from the coin stock 18. Therefore, even if the conveyance belt is clogged due to the accumulation of coins in the vicinity of the dispensing shutter 206 or the collection shutter 208, it is possible to automatically recover the jam.

In order to achieve the above-mentioned object, the coin jam removing method of the coin processing device of the present invention is to discharge the coins stored in the coin stock to the conveyor belt 204, and to rotate the conveyor belt 204 in the forward direction to discharge the coins. 22 and the coins are paid out, and at the same time, the conveyor belt 204 is reversed to collect the coins.
It is applied to a coin processing device that transports the coins to the coins 4 and collects the coins. That is, the step of detecting the locked state of the conveyor belt 204; the step of suppressing the discharge of coins from the coin stock 18 and the operation of removing the locked state of the conveyor belt 204 when the locked state is detected. And; the step of restarting the coin discharge from the coin stock 18 when the locked state of the conveyor belt 204 is released by the lock release operation.

The operation of the apparatus configured as described above will be described separately for the depositing operation, the dispensing operation, and the collecting operation. FIG. 4 is a flow chart for explaining the deposit operation. First, coins are inserted from the insertion slot 10 and stored in the feeding section 12 (S10).
0). The coins stored in the feeding section 12 are separated one by one and conveyed to the identifying section 14 (S102). The coins conveyed to the identification unit 14 are identified, counted, and conveyed to the distribution unit 16 (S104). The denomination and the counting data by the identifying unit 14 are transmitted to the control unit 30.

The coins transported to the sorting unit 16 are sorted by denomination (S106). The distribution of denominations is counted and allocated to slots of the circulating change unit 18 corresponding to each denomination by a distribution plate (not shown) provided with holes of the denomination of the distribution unit 16. For example, in the case of sequentially sorting coins having a small outer diameter, a distribution plate matching the outer diameter of each coin is provided in the order of 50-yen coin, 100-yen coin, 10-yen coin, and 500-yen coin.

When the identifying unit 14 identifies the reject coin to be returned (S108), an output from the control unit 30 activates a gate (not shown) provided at the frontmost stage of the sorting unit 16, It is distributed to the return chute 142, and passes through the reject coin return port 218 to release port 22.
Is returned to the saucer 23 (S110). The coins to be returned include, for example, foreign coins, old coins that are not currently accepted, mere metal medals, and coins that have a universal ability, but are difficult to distinguish from counterfeit coins because the degree of damage is significant.

When a transaction operation is performed by the user (S11
2) The control unit 30 compares the deposit amount with the transaction amount (S114). If there is a change, the process proceeds to the withdrawal operation (S116). Further, although not shown, when the return operation is performed by the user before the transaction operation, the circulation change unit 18
Is activated and the deposit amount is returned. In addition, circulation change section 1
Details of the discharging operation of No. 8 are described in the relevant portions of the following dispensing operation.

FIG. 5 is a flow chart for explaining the dispensing operation.
First, the control unit 30 compares the deposit amount with the transaction amount, and outputs a change output command to the circulating change unit 18 in order to discharge coins corresponding to the difference as change (S200). Based on the change output command, the circulating change unit 18 operates the discharging mechanism for each slot of the corresponding type of coins, and discharges the coins to the withdrawal and transport unit 20 while counting the coins (S202). For example, when paying out 110 yen as change, the discharge mechanism of the 10-yen coin slot and the 100-yen coin slot or the 50-yen coin slot operates, but the discharge mechanism of the 500-yen coin slot does not operate.

At this time, the transfer belt 2 of the dispensing transfer unit 20
04 is stopped, and the dispensing shutter 206 and the collection shutter 208 are also closed. Then, it is determined whether or not there is an abnormality in the change release by the circulating change unit 18 (S
204). If no abnormality has occurred, circulation change unit 1
Change by 8 to the withdrawal transfer unit 20 (or return)
When all the coins have been discharged, the dispensing shutter 206 is released (S206). Then, the conveyor belt 204 is normally rotated to convey the coin to the discharge port 22 (S208), and the dispensing operation is completed. At this time, the collection shutter 208 is closed and the release to the collection box 25 is prevented.

If the change release by the circulating change section 18 is abnormal, the collection shutter 208 of the dispensing and transfer section 20 will be described.
Is released (S210). Next, the conveyor belt 204 is reversed and the coins are stored in the collection box (S212). And
The collection shutter 208 is closed (S214) and S202.
Then, the operation from S202 is retried.

6 and 7 are flow charts for explaining the recovery operation. FIG. 8 is a time chart for explaining the collecting operation,
(A) is the collection shutter 208, (B) is the transport motor 21
2, (C) shows the discharge motor of the circulation change section 18, and (D) shows the detection sensor 224. Here, there are the following two types of recovery. The first type is performed by a staff member of the transaction device 2, and is an operation of collecting all coins in the circulating change section 18. The second type is an operation of collecting only some coins of the corresponding circulating change section 18 when the storage section is full due to the circulation processing. The following explanation is the first
The types of will be described. For the second type, first
You should read carefully the types of coins that should be collected.

First, an operator operates the operation unit 27 of the transaction device 2.
When a collection instruction is given by an operation such as (S300),
The signal to be collected is output to the control unit 30 of the coin processing device 1 (S302). In the control unit 30 of the coin processing device 1,
The output to be collected is input (S402). Then, the control unit 30 outputs a processing start signal to the circulating change unit 18 and the dispensing transfer unit 20 by the change unit control unit 32 and the transfer unit control unit 34 (S404).

Based on the output from the control unit 30, the dispensing transfer unit 20 closes the dispensing shutter 206 (S406) and releases the collection shutter 208 (S408; P shown in FIG. 8).
1), the conveyor belt 204 is reversed by the conveyor motor 212 (S410; P2 shown in FIG. 8). In addition, the control unit 30
The detection by the transport state detecting means 36 is started (S41).
2; P3 shown in FIG. 8). The circulation changer 18 operates all the discharging mechanisms based on the output from the controller 30 (P4 shown in FIG. 8), and discharges the coins in the slot to the conveyor belt 204 of the dispensing conveyor 20 (S414).

The coins discharged from the circulating change section 18 are conveyed to the collecting port 24 by the conveying belt 204 and the collecting box 25.
Is stored in. When the delivery state detecting unit 36 of the control unit 30 does not detect the locked state (S416) and the release from the circulation change unit 18 is completed, the operation of the release mechanism is stopped, and the operation from the circulation change unit 18 is stopped. (S418). At this time, the conveyor belt 204 is stopped after being conveyed for a certain period of time (S420), the collection shutter 208 is closed (S422), and a collection completion signal for notifying that the collection is completed is output to the transaction device 2 to output the coin processing device 1. The collection operation of is finished (S424). The transaction device 2 displays the fact on the operation unit 27, for example, by the input collection end signal, and finishes all the collection processing (S304).

When the locked state is detected by the conveyance state detection means 36 of the control section 30 (P6 shown in FIG. 8), a detection signal is output to the change section control means 32 and the unlocking means 38 (S430). The change unit control means 32, to which the information indicating that the locked state has been detected is input, temporarily stops the operation of the release mechanism of the circulating change unit 18 (S432; P shown in FIG. 8).
7). The unlocking means 38, to which the fact that the locked state is detected, is input, executes the operation of the withdrawal / transporting section 20 via the transporting section control means 34 by the unlocking program (S4).
34). The operation of the unlock program operates P8 to P13 and t2 to t4 shown in FIG. 8, which will be described in detail later.

Next, after the unlocking operation of the dispensing / conveyance unit 20 (S436), the normal conveyance (reverse rotation) at the time of collection is carried out (S).
438; P13 shown in FIG. 8), and the transport state detecting means 36 performs lock detection (S440; P1 shown in FIG. 8).
4). When the release of the locked state is confirmed by the conveyance state detection means 36 (P15 shown in FIG. 8), that effect is output to the change section control means 32 (P1 shown in FIG. 8).
7) and returns to S414 to repeat the operation.

On the other hand, when it is not confirmed by the conveyance state detecting means 36 that the locked state is released (P18 shown in FIG. 8), the unlocking operation (from P19 shown in FIG. 8) is performed a predetermined number of times (S442). If the operation is not canceled even after the predetermined number of operations, it is determined as an abnormality and the coin processing device 1 is completely stopped (S444). In this case, the operation of the transaction device 2 may be stopped if necessary, but if there are other banknote processing devices or card processing devices, the handling by the coin processing device 1 may be stopped.

Next, with reference to FIG. 8, the details of the detection of the lock state and the operation of the lock release program in the recovery operation will be described. When the detection sensor 224 is an optical type such as a photo interrupter, the conveyance state detection means 36 monitors the time from the end of the light blocking of the detection sensor 224 to the end of the next light blocking. In this light-shielding interval monitoring, when there is no light-shielding within a predetermined time (t1), it is regarded as a locked state, and the transport state detection means 36 outputs detection of the locked state to the change section control means 32 and the unlocking means 38 ( P6). It is preferable that the predetermined time (t1) is set to be a little larger than the light-shielding interval detected by the detection sensor 224 in the normal coin transportation which is not in the locked state due to the transportation operation of the transportation belt 204.

As for unlocking, unlocking means 38 is used.
Of the transport motor 212 for a predetermined time (t2) (P8 to P10) and a predetermined time (t
3) Forward rotation (P10 to P12) and stop (P12 to P13) for a predetermined time (t4) are driven. The stop time is, for example, a time normally required for a coin to fall from the state where it stands on the conveyor belt 204 to fall on the conveyor belt 204 and settle. The forward rotation time is, for example, the time for driving the transport motor 212 to the extent that the transport belt 204 moves about the outer diameter of the coin. Then, when the conveyance motor 212 is stopped for a longer time, the conveyance motor 212 starts to rotate in the reverse direction (P13), and the conveyance state detection means 36 starts detecting the locked state (P14).

When the locked state is released, the detection sensor 224 is shielded from light within a predetermined time (t5; however, t5 <t6), and the normal operation is resumed (P15). On the other hand, if the locked state is not released, within a predetermined time (t6; however, t6 = t
Since the detection sensor 224 does not block light in 1), the time is up (P18). Therefore, the transport motor 21
2 from the stop of driving (P19), the operation of the sequence program of the unlocking means 38 (P8 to P
15) is performed a predetermined number of times (see the chain double-dashed line on P19).

[0039]

As described above, according to the coin processing device of the present invention, the coins stored in the coin stock are discharged onto the conveyor belt, and the conveyor belt is normally rotated and conveyed to the discharge port. In a coin processing device that pays out the coins, reverses the conveyor belt and conveys the coins to the collection port, and collects the coins, a detection sensor that detects a conveyance state of coins by the conveyance belt, and the conveyance by the detection sensor. When the locked state of the belt is detected, the coin release from the coin stock is restrained, and the lock released by the conveyor belt is released. By operation,
