BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a control device for a feeding roller and a gate roller as a feeding unit for feeding out the picked-up bills to a feeding means when the bills in a storage cassette are separated and taken out one by one. It is about.

[0002]

2. Description of the Related Art Conventionally, in an automated teller machine such as an automated teller machine, a storage cassette for storing banknotes and a separating roller for sequentially separating and taking out the banknotes in the storage cassette one by one during a payment transaction. And a feeding unit configured to feed the separated and picked-up bills to a feeding belt, the feeding unit including a feeding roller and a gate roller. When the number of banknotes in the storage cassette is low, the sensor detects that the remaining amount is low, and when the specified number of banknotes has been paid from the storage cassette for the transaction, it is determined that the banknote needs to be replenished. , The device has been discontinued.

[0003]

In the prior art described above, the thickness of the remaining banknotes in the storage cassette is detected by the sensor, so that the actual number of remaining banknotes varies greatly depending on the state of the banknotes. Yes, in order to guarantee the maximum number of bills to be paid for one transaction, dozens of banknotes are left in the storage cassette even when the replenishment is required. For this reason, if a state in which several tens of banknotes remain and a replenishment required state is reached, the banknotes become dead banknotes by that amount, so that the operation efficiency is inevitably deteriorated. In order to solve this problem, it is easy to think that the banknotes in the storage cassette will be used up until it is empty, but in that case, the banknotes must be taken out until the storage cassette is empty. Therefore, even if the bill is completely taken out from the storage cassette, it is necessary to cause misfeed such that the separating roller and the feeding unit are driven to rotate. However, in the above-mentioned conventional technology, the conveyance roller of the feeding unit rotates while the bill roller passes through the feeding unit, while the gate roller is stopped, and when the bill passes, both the conveyance roller and the gate roller. Since it is configured to rotate, when misfeed occurs, the conveying roller and the gate roller in the feeding section are in sliding contact with each other, and only the conveying roller rotates, which causes both rollers to wear. There is. Also, in case of misfeed, in order to confirm that the storage cassette is completely emptied, as a result of performing the bill payout retry multiple times, only the transport roller is repeatedly rotated in sliding contact with the stopped gate roller. Therefore, the wear of both rollers is further promoted, and the life is shortened remarkably.

In view of the above problems of the prior art, it is an object of the present invention to provide a bill feeding control device for an automatic cash machine, which is capable of extending the lives of the conveying roller and the gate roller of the feeding portion. .

[0005]

In order to achieve the above object, in the present invention, at the time of separating and taking out discharged banknotes from the storage cassette by the separating roller, both the conveying roller and the gate roller of the feeding section are rotated. Then, when the discharged bill passes through the feeding unit, it has a feeding unit control means for rotating one of the transport roller and the gate roller of the feeding unit and stopping the other.

[0006]

According to the present invention, as described above, when feeding out a bill, the feeding roller and the gate roller of the feeding portion are rotated by the feeding portion control means, and the bill separated and taken out from the storage cassette by the separating roller is fed. When passing between the roller and the gate roller, either one of the rollers is rotated and the rotation of the other roller is stopped, and the banknote is passed between the transport roller and the gate roller by the rotational force of the one roller. Even if both the transport roller and the gate roller are in sliding contact with each other, wear can be prevented as much as possible.

.. to 2c are provided with pressing plates 11a to 11c for pressing the stored bills 12a to 12c, respectively, and the separating roller 2a.
When ~ 2c is rotated, the corresponding bills 12a to 12c are separated one by one and taken out from the storage cassette. Further, on the outlet side of the storage cassettes 1a to 1c, the conveying rollers 3a to 3c as the feeding unit and the gate rollers 4a to 4a.
4c is attached, and when the corresponding bills 12a to 12c are separated and taken out by the separating rollers 2a to 2c, the respective bills are sent to the conveying belt by the conveying rollers 3a to 3c and the gate rollers 4a to 4c. I am trying. These transport rollers 3a to 3c and gate roller 4a
To 4c are arranged so as to be in sliding contact with each other, and are configured so that their peripheral velocities coincide with each other so that the relative rotational velocity becomes zero. In FIG. 3, the transport rollers 3a to 3a are
Although c is illustrated as being driven by motors 5a-5c, gate rollers 4a-4c and separation motor 2a are shown.
2c are independently driven by motors (not shown). The conveyor belt is the upper conveyor belt 7
When the banknote 12c in the lowermost storage cassette 1c is sent to the lower part of the conveyor belt 7B by the conveyor roller 3c and the gate roller 4c, the conveyor belt 7B is driven to the upper part by driving the conveyor belt 7B. Is fed to the conveyor belt 7A, and further the conveyor belt 7A
After being sent to the pair of discharge belts 9a and 9b, the discharge belts 9a and 9b discharge the light to the receiving port 10. On the other hand, the banknote 1 in the middle storage cassette 1b
When 2b is sent to the midway position of the carry belt 7B by the carry roller 3b and the gate roller 4b, it is carried to the carry belt 7A and the discharge belts 9a and 9b from the midway position in the same manner as described above, so that the receiving port 10 Is released to. On the other hand, the banknotes 12a in the upper storage cassette 1a
Is fed to the lower part of the transport belt 7A by the transport roller 3a and the gate roller 4a, and is discharged through the transport belt 7A and the discharge belts 9a and 9b. The conveyor belts 7A and 7B are driven by the conveyor motor 6,
The discharge belts 9a and 9b are driven by discharge motors 8a and 8b. Further, the banknotes 12a-12 stored in the respective storage cassettes 1a-1c.
There are provided remaining amount sensors 13a to 13c for detecting that the amount of c is low. As shown in FIG. 4, when the banknotes 12 in the storage cassette are separated and taken out by the separating roller 2, the cash automatic machine of the embodiment is provided with a position detection sensor 14 that detects the taken-out banknotes 12. Has been done. The position detection sensor 14 is shown in FIG.
As shown in FIG. 3, the banknote 12 is located below the separation roller 2 and the storage cassette and located in the carry-in section between the transport roller 3 and the gate roller 4, and the bill 12 is separated from the storage cassette by the separation roller 2 and taken out. When it is located in the carry-in section, it is detected. Then, when the position detection sensor 14 detects the banknote 12, for example, the rotation of the gate roller 4 among the transport rollers 3 and the gate rollers 4 that have been rotating until then is stopped and the rotation of the transport roller 3 is continued. I have to. Therefore, when the position detection sensor 14 detects the bill 12, the control unit (not shown) that stops the rotation of the gate roller 4 constitutes a bill feeding control device. Incidentally, in FIG. 4, the conveying roller 3, the gate roller 4, the separating roller 2,
Each of the holding plate 11 and the banknote 12 includes the transport rollers 3a to 3a of FIG.
3c, gate rollers 4a to 4c, separation rollers 2a to 5
Reference numeral 15 denotes a conveyance path arranged between the conveyance roller 3, the gate roller 4 and the conveyance belts 7A and 7B in accordance with c, the pressing plates 11a to 11c, and the bills 12a and 12c.

Hereinafter, a bill feeding control operation by the control unit will be described with reference to FIG. In the case of payment transaction, the control unit starts the bill feeding control operation (010), and rotates the separating roller 2 and the conveying roller 3 and the gate roller 4 as the feeding unit (020), and then the separating roller 2 rotates. The banknotes 12 are separated from the desired storage cassette and fed out, and are sent to the loading section side between the transport roller 3 and the gate roller 4. Meanwhile, the position detection sensor 14 determines whether the banknotes 12 separated by the separation roller 2 have been fed (030). As a result of the judgment, the conveyance roller
When the position detection sensor 14 detects the banknote 12 sent to the carry-in section between the gate roller 4 and the gate roller 4, the control section stops the rotation of the gate roller 4 and keeps the transport roller 3 rotating (040), The banknote 12 is sent to the transport path 15 by passing the banknote 12 between the transport roller 3 and the gate roller 4 only by the rotation of the transport roller 3.
On the other hand, if the position detection sensor 14 does not detect the banknote 12 as a result of the determination, the control unit repeatedly executes the processing of steps 030 and 090 until the position detection sensor 14 detects the banknote, if the position detection sensor 14 is within the specified time, If the banknote is not detected after the stipulated time has passed, it is judged as "banknote misfeed" (100), and then the driving of the separation roller 2, the conveyance roller 3 and the gate roller 4 is released (130). , It ends abnormally. In this case, the conveyance roller 3 and the gate roller 4 are rotating until the position detection sensor 14 does not detect a bill and abnormally ends, but both rollers 3 and 4 remain in contact with each other. Since it rotates in the state and the relative rotation speed is 0, it is possible to prevent abrasion. After the processing of step 040, the position detection sensor 14 determines whether the banknote 12 has passed the position detection sensor 14 (050). As a result of the judgment, the position detection sensor 1
When 4 detects that there is no bill, the control unit rotates the gate roller 4 again and waits for the next bill to be fed (060), and then determines whether or not the designated number of bills have been fed. If the designated number of bills has not been fed out, the processing from step 030 is repeatedly executed, and when the designated number of bills is fed out, the drive of the separation roller 2, the transport roller 3, and the gate roller 4 is stopped (080 ), Consider it a normal end. In the process of step 050, when the position detection sensor 14 detects a bill, the control unit determines whether it is within a specified time (11
0), steps 050 and 1 until the specified time has elapsed
When the process of 10 is repeatedly executed and the specified time has elapsed,
It is judged as a "paper money jam" (120), and the processing of step 130 is executed in the same manner as described above, whereby the processing ends as an abnormality.

As described above, in the embodiment, when the bills are fed out, the separation roller 2 is rotated, and at the same time, the conveying roller 3 and the gate roller 4 in the feeding portion are all rotated, and the separation roller 2 is used to remove the bills from the storage cassette. When the banknotes 12 that have been separated and taken out pass between the transport rollers 3 and the gate rollers 4, the rotation of the gate rollers 4 is stopped, and the banknotes are moved between the transport rollers 3 and the gate rollers 4 by the rotational force of the transport rollers 3. Since it is passed, even if both the transport roller 3 and the gate roller 4 are in sliding contact with each other, abrasion can be prevented as much as possible.

The above operation has been described when there are a large amount of bills remaining in the storage cassettes, that is, when the small amount sensors 13a to 13c in the respective storage cassettes 1a to 1c do not detect. A case in which the small amount sensors 13a to 13c detect will be described with reference to FIG. FIG. 2 shows a case of payment transaction of a denomination corresponding to the banknote 12c in the storage cassette 1c, for example, the control unit first sets the banknote payout retry count to 0 (200), and then separates the banknotes. The bill feeding operation is started by rotating the roller 2c, the feeding roller 3c of the feeding portion, and the gate roller 4c (210). At this time, the banknote 12c in the storage cassette 1c is separated and taken out by the separation roller 2c and passes between the transport roller 3c and the gate roller 4c.
It is determined whether or not misfeed is detected (220). Then, when misfeed does not occur and the banknotes 12c are sequentially fed out by passing the banknotes between the transport roller 3c and the gate roller 4c, the banknote 12c ends normally. The bill 12c is the separating roller 2
banknotes 12 from the desired storage cassette 1c by rotation of c
When c is separated and taken out and sent to the carry-in side between the transport roller 3 and the gate roller 4, the rotation of the gate roller 2 is stopped as in the above-described embodiment. on the other hand,
When misfeed occurs in step 220, the control unit checks whether the remaining amount of the banknotes 12c in the storage cassette 1c is small via the small amount sensor 13c (230). At this time, when the remaining amount sensor 13c detects that the remaining amount of bills is low, the storage cassette 1c is recognized as empty, and it is determined as a "replenishment bill required error" (240). The banknote 12c is not delivered from the storage cassette 1c, and the process proceeds to step 280 described later. Also, in step 230,
If the remaining amount of the banknotes 12c in the storage cassette 1c is not small, it is inspected whether or not the number of times the banknotes have been fed out has been tried a predetermined number of N times (250). It is counted (260), and the processing from step 210 is repeatedly executed, but when the number of times reaches N,
Judge as "misfeed error", and step 280
Process. That is, in step 280, the bill 1
It is checked whether or not there is a banknote of the same denomination as that of 2c in any of the other storage cassettes 1a and 1b, and as a result, if it is not in any of the storage cassettes 1a and 1b, the control unit suspends the handling. If there is a banknote of the same denomination in any of the storage cassettes 1a and 1b, the control target is switched to the storage cassette in which the banknotes are stored (290), and the designated storage cassette is designated for payment transaction. After setting the number of remaining banknotes among the number of banknotes (300), the processing from step 210 is repeatedly executed for the banknotes in the switched storage cassette. Therefore, in the automated teller machine of this embodiment, it is premised that the banknote 12c in the storage cassette 1c and the banknote in either one of the other storage cassettes 1a and 1b have the same denomination. It will be.

In this embodiment, as described above, the banknotes 12c are sufficient for the storage cassette 1c, and the banknotes necessary for the payment transaction while the low remaining amount sensor 13c does not detect that the remaining amount of the banknotes 12c is small. When misfeed of 12c occurs, the separation roller 2c and the conveying rollers 3c and 4c of the feeding section
When the feeding operation of the banknote 12c is tried a predetermined number of times by driving, and when the remaining amount of the banknote 12c is detected to be small by the detection of the remaining amount sensor 13c, and the misfeed of the banknote 12c occurs. , The storage cassette 1c is recognized as empty when the remaining amount of banknotes in the storage cassette 1c becomes small, and the transport roller 3 of the feeding unit 3
c and the gate roller 4c are not driven, the rollers 3c and 4c are not driven unnecessarily,
It is possible to prevent the two from wearing each other. In addition, when misfeed occurs, unless the remaining amount of banknotes in the storage cassette 1c becomes small, the banknote payout can be retried a specified number of times, and the banknote payout can be performed even if the specified number of times is retried. No, and the banknote 12 in the storage cassette 1c
When the remaining amount of c is low, another storage cassette 1
When the banknotes of the same denomination are stored in either a or 1b, the remaining number of banknotes necessary for the transaction is fed out from the other storage cassette, so that the banknotes in the other storage cassette are valid. Can be used for.

In the illustrated embodiment, an example in which the rotation of the gate roller 4 of the conveying roller 3 and the gate roller 4 of the feeding portion is stopped when a bill passes is shown, but in the present invention, the conveying roller 3 is used. However, the same effect can be obtained, and the point is that the desired function can be achieved by stopping the rotation of either one.

[0013]

As described above, according to claim 1 of the present invention, when the bill is separated by the feeding roller, the conveying roller and the gate roller of the feeding unit are rotated, and when the bill passes, the feeding unit is operated. Since the rotation of either one of the transport roller and the gate roller is stopped and the other rotation causes the banknote to pass between the transport roller and the gate roller, when the banknote does not pass, the transport roller 3, the gate roller 4 It is possible to minimize the sliding contact of both of the rollers and suppress the abrasion of both rollers, and as a result, it is possible to extend the service life of both rollers and provide a highly reliable and durable device. effective. According to claim 2, in addition to the effect of claim 1, when a misfeed of banknotes necessary for payment transaction occurs, the storage cassette becomes empty when the remaining amount of banknotes in the storage cassette becomes small. Therefore, there is an effect that both rollers are not driven unnecessarily, and the life can be further extended.
