Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention separates handled paper sheets (banknotes, etc.) one by one and sends them to a discrimination / counting unit for discrimination and counting, and then a predetermined result based on the discrimination result. The present invention relates to an anomaly processing method for coping with an anomaly that occurs in the process of separating, carrying, and accumulating handled paper sheets, in a paper sheet handling apparatus having a discrimination / counting function of sorting and accumulating in a plurality of accumulating sections via a conveying path. .

[Conventional technology]

In an automated teller machine, which is a typical example of a paper handling apparatus having a discrimination / counting function, banknotes conveyed from a separation unit to a stacking unit through a discrimination / counter unit at the time of a transaction are jammed in the stacking unit. May occur or get caught and remain in the middle of the conveyance path. Conventionally, when such an abnormality occurs, a clerk inspects the inside and removes the jammed banknote, but if the banknote remains in the transport path,
The conveyance path was forcibly driven, the residual banknote detected by the passage detection sensor in the conveyance path was removed, and the device was restored.

[Problems to be solved by the invention]

In this type of conventional device, since the device itself does not consider to automatically recover the device by eliminating jammed bills in the stacking unit and residual bills in the transport path when the abnormality occurs, it is necessary to perform restoration processing by an attendant. We were not able to handle unmanned operations such as automated teller machines. In addition, even if the conveyance path is forcibly driven, the remaining banknotes cannot be conveyed, and if the operation of the device is restarted with the banknotes remaining between the passage detection sensors, the remaining banknotes will be conveyed during the next transaction. It was not possible to prevent the cash transaction accident from being mixed in the bill.

The present invention has been made to solve the above-mentioned problems of the prior art, and when an abnormality occurs, the apparatus itself reliably removes jammed paper leaves in the stacking unit and residual paper leaves in the transport path, and An object of the present invention is to provide an abnormality processing method for a paper sheet handling apparatus, which can automatically restore the apparatus after confirming that separation and conveyance are normally performed, and which is suitable for unmanned operation with few accidents. .

[Means for solving problems]

In order to achieve the above-mentioned object, the present invention, as shown in the outline in FIG. 1, separates the handled paper sheets 10 one by one by a separating unit 41 and sends them to a discrimination / counting unit 42 for discrimination and counting, and then for discrimination. As a result, a plurality of stacking units 44, 45, 46 are passed through a predetermined transport path 43.
In a paper sheet handling apparatus having a discrimination / counting function for sorting and accumulating paper sheets, means 9 for detecting the occurrence of an abnormality in the process of separating, conveying, and accumulating the paper sheets 10 and the paper sheets 10 and the identifiable check The sheet 51 is supplied to the separating unit 41,
Checking sheet 51 detected by the transporting means 3 for taking out the stacks in the stacking sections 44, 45, 46, the discrimination counting section 42 and the passage detection sensors 48a to 48e in the transport path 43.
Means 103 for comparing the number and length of the check sheets with the prescribed number and length to determine whether the separation and conveyance of the check sheet 51 are normally performed, and the abnormality detecting means 9 detects the occurrence of an abnormality. In this case, after the stacks 44, 45, 46 are taken out by the carrying means 3, a specified number of check sheets 51 are supplied to the separating part 41 by the carrying means 3 and the discrimination counting section is supplied. The check operation is performed once or a plurality of times by the determination means 103 to determine whether or not the check sheet 51 has been separated and conveyed normally by being accumulated in the accumulating sections 44, 45 and 46 via the 42 and the conveying section 43. The operation is repeated, and when it is determined that the operation is normal, the operation of the device is automatically restarted.

[Action]

When an abnormality occurs, for example, when the occurrence of a jam in the stacking unit 44, 45, 46 is detected by the abnormality detecting unit 9, the paper sheet in the stacking unit in which the jam has occurred is taken out by the transporting unit 3. Next, the separating unit 41, the discrimination counting unit 42, and the conveying path 43 are activated, and the paper sheets remaining in these units are accumulated in the accumulating units 44, 45, 46 and taken out by the conveying means 3. After emptying each part in this way, the specified number of check sheets 51 are supplied to the separating part 41 by the transporting means 3 to check the differential counting function. The length of the check sheet 51 is changed so that the check sheet 51 can be distinguished from the handling paper sheet 10. The check sheets 51 separated one by one are passed through the discrimination / counting unit 42 and the conveying path 43 to the stacking units 44, Collect at 45 and 46. At that time, if the number and length of the check sheets detected by the differential counting unit 42 and the passage detection sensors 48a to 48e match the specified number and length, respectively, the determination unit 103 determines that the differential counting function is normal. To do. If the determination result is normal, the accumulated check sheets 51 are returned to a predetermined storage position in the device by the transporting means 3 and the operation of the device is automatically restarted (105).

When the paper sheet remains in the transport path 43, the residual paper sheet is pushed out by the check sheet sent to the transport path 43. Residual paper stacks together with check sheet 51
Passage detection sensors 48c to 48e that are integrated in 44, 45, 46
In the case of being detected by (1), the collected check sheets and paper sheets are separated and collected by passing through the separating unit 41 and the discrimination counting unit 42 again. When this separation is performed normally, the operation of the device is automatically restarted.

Passed,
Further, the surplus bills in the separating unit 41 are delivered to the bill storing unit 2 by the hand 31.

Next, the abnormality processing of the differential counting mechanism unit 4 will be described.

FIG. 6 shows a jam detecting mechanism 9 which is one of abnormality detecting means.
A configuration example of is shown. 91 is the bottom plate of the stacking unit, the fulcrum shaft in the center
It is supported on a pedestal 93 via 92 so as to be swingable in the front-rear direction, and is normally kept in a horizontally balanced state as shown by a broken line by springs 94 and 95 interposed between the pedestal 93 and the pedestal 93. There is. 96 is a support spring provided under the pedestal 93, which works to press the bottom plate 91 toward the belt 43a of the conveyance path 43,
As the banknotes 10 sent out between the belts 43a and 43b are accumulated on the bottom plate 91, the bottom plate 91 compresses the support spring 96 together with the pedestal 93 and moves down. Reference numeral 97 is a photo interrupter attached to the pedestal 93, and 98 is a light shielding plate provided at one end of the bottom plate 91. The shading plate 98 has its groove portion 98a always located in the optical path of the point interrupter 97 and does not shield light, but it does not block bills in the stacking unit.
When the 10b is buckled and a jam occurs, the bottom plate 91 is pushed by the jam paper sheet 10b and becomes inclined as shown by the solid line, and the shading plate 98 shields the photo interrupter 97 to prevent jamming. Detected. The jam detection mechanism 9 is installed in each of the stacking units 44, 45, 46 and sends a signal to the control unit 7 when a jam occurs.

When bills remain in the transport path 43, the discrimination counting unit 42
Since the number of banknotes detected in 1. does not match the number of banknotes detected by the passage detection sensors 48c to 48e, the control unit 7 can detect an abnormality.

When the occurrence of an abnormality such as a jam or a remaining bill is detected, the control unit 7 stops the transaction operation in progress and performs the abnormality processing described below according to a preset control program. The flow of abnormality processing is shown in FIG.

When an abnormality occurs, for example, when a jam occurs in any of the stacking units 44, 45, 46, first, in step 101, the jam banknotes are removed and the remaining banknotes in the discrimination counting mechanism unit 4 are removed by a command from the control unit 7. Done. That is, when the occurrence of a jam is detected, the operation of the discrimination / counting mechanism unit 4 is stopped, the banknote is taken out from the stacking unit in which the jam has occurred by the hand 31 of the rear portion 3 of the transporting machine, and the banknote take-in / takeout unit 1 is carried out when depositing. , At the time of payment, after passing to the reject bill collection box 6, the discrimination counting mechanism unit 4 is restarted, and the bills remaining in the separating unit 41, the discrimination counting unit 42 and the transport path 43 are collected in a predetermined stacking unit, for example, 46. And the hand 31 on the rear part 3 of the carrier.
In the same manner, the bills are delivered to the bill taking-in / taking-out section 1 or the reject bill collecting box 6.

If it is detected that the banknotes remain on the transport path 43, the banknotes have already been transported, so the banknotes stacked in the stacking units 44, 45, and 46 are taken out by the hand 31, and the banknotes are taken in when depositing. At the time of payment, the bill is delivered to the take-out section 1 or the bill storage section 2 or the reject bill collection box 6.

After taking out the jam banknotes and the remaining banknotes, step
At 102, the specified number of check sheets 51 stored in advance in the control section 7 is delivered from the check sheet storage section 5 by the hand 31 to the separating section 41, and the function check of the discrimination counting mechanism section 4 by the check sheet 51 is started. . As shown in FIG. 7, the check sheet 51 has different length dimensions 1 in the carrying direction, or paper with an identification code recorded on the magnetic stripe 51a on the surface, in order to be able to identify it as a handling bill. It is made of thin material such as plastic. The check sheet 51 supplied to the separating unit 41 as shown in FIG.
While the number of sheets and the length l shown in FIG. 7 are detected at 48a to 48e, they are sorted and stacked in the stacking units 44, 45, 46.

Step 103 corresponds to the function check determination means in FIG. In this step, the number and length of the check sheets detected by the discrimination / counting unit 42 and the passage detection sensors 48a to 48e are compared with the prescribed number and length stored in the control unit 7, and if they match, it is normal. To determine.

If the determination result is normal, the process proceeds to step 104, and the accumulation unit 4
The check sheets 51 accumulated on 4, 45 and 46 are delivered to the check sheet storage section 5 by the hand 31. This completes the check operation, and in step 105, the deposit or payment transaction operation is restarted.

As an example when it is determined to be abnormal in step 103,
As shown in FIG. 3, the bill 10a may remain in the transport path 43. In this case, the remaining banknote 10a
It is pushed out by the check sheet 51 sent inside,
Since the check sheet 51 is conveyed and accumulated together with the check sheet 51, the length l of the check sheet 51 overlapping the remaining banknote 10a is determined by the control unit
Detected longer than the specified length stored in the
It is judged to be abnormal in 103. Further, due to the separation failure of the separation unit 41, two or more check sheets 51 may be taken in in an overlapping manner. In this case, the discrimination counting unit 42 and the passage detection sensors 48a to 48e count the number of check sheets 51 less than the specified number stored in the control unit 7, so that it is determined to be abnormal in step 103.

When it is determined that there is an abnormality in this way, the process proceeds to step 106, and the stacks (check sheets + remaining banknotes) of the stacking units 44, 45, 46 are delivered to the separating unit 41 by the hand 31, and are separated and conveyed again. The remaining banknotes are stacked in the stacking unit 44, and the check sheet 51 is stacked in the stacking unit 45 or 46.

When it is determined in step 107 that the check sheet 51 has been separated and conveyed normally, in step 108, as shown in FIG. 8B, the remaining bills are collected from the stacking unit 44 into the reject bill collection box 6 or bills. The check sheet 51 is transferred from the stacking unit 45 or 46 to the check sheet storage unit 5 by the hand 31 to the loading / unloading unit 1. This completes the check operation and restarts the trading operation (step 105).

If it is determined to be abnormal again in step 107, the separation unit 4
Since there is often a failure in the device itself, such as 1 or the transport path 43, the device is discontinued and a clerk performs recovery processing (step 109).

Even if it is once determined to be normal in step 103, the reliability is further improved by re-separating and transporting the collected check sheets as necessary and repeating the function check a plurality of times.

〔The invention's effect〕

According to the present invention, by separating, conveying, and stacking a specified number of check sheets when an abnormality occurs in the differential counting mechanism unit,
The paper sheet that remains between the passage detection sensors in the transport path can be reliably eliminated by the device itself, preventing the occurrence of cash transaction accidents during the next paper sheet transport, and the device itself can identify it. The function of the counting mechanism is checked, and the equipment is automatically restored except when there is a failure in the equipment itself such as the separation part or the transport path, so the restoration process by the staff is minimized and the automated teller machine is unmanned. Operation can be possible.
