Description

DETAILED DESCRIPTION OF THE INVENTION (a) Technical Field The present invention relates to a paper sheet feeding control device for feeding paper sheets one by one from a paper sheet feeding unit at a constant interval and discriminating them to sort them into normal ones and abnormal ones. In particular, the present invention relates to a device for stopping jamming due to abnormal feeding by stopping the conveyance monitoring of the paper fed abnormally from the paper feeding unit.

(B) Background of the Invention Generally, in this type of banknote payout control device, as shown in FIG. 1 (A), a second banknote C2 is a banknote C2 after a first banknote C1 with a predetermined space D therebetween. The bills are fed from the bill feeding unit K one by one at regular intervals such that the bills are fed from the feeding unit K. Then, in the transportation process, it is common to monitor the bills while counting them one by one. However, as shown in FIG.
If the bills C1 'and C2' are fed at a narrower interval d (<D), the bills C1 'and C2' that have been fed due to an abnormal approach may overlap during conveyance. If such an overlap occurs in the middle,
Since both C1 'and C2' are monitored separately from the feeding start, they are counted as if one banknote was being conveyed, and a counting error occurred and they were treated as jams. It was Further, as shown in FIG. 6C, when two banknotes C1 ″ and C2 ″ are taken out in an overlapping manner, they may be separated in the middle of the transport path. In this case also, the bill C1 ″ that was brought out in an overlapping manner
Since C2 ″ is judged as one sheet and monitored, it was counted as two sheets during transportation, and it was treated as a jam treatment due to a count error. As described above, abnormal approach feeding or overlapping feeding was performed. If this occurs, the number of jams will be increased and the operating rate of the device will decrease.To prevent this, the sorting flapper is sorted according to the sorting result in the sorting unit and the count error target is set. Even if the abnormal payout bills are collected, it is difficult to completely prevent the occurrence of the above jam because the response of the sorting flapper to the discrimination unit is slow.

(C) Object of the invention In view of the above circumstances, the object of the present invention is to provide the above-mentioned FIG. 1 (B),
When the abnormal approach feeding or the overlapping feeding shown in (C) occurs, it is possible to prevent the occurrence of jam due to the abnormal feeding and to reduce the jam ratio by not performing the conveyance monitoring for the paper sheets that are the target of the count error. An object of the present invention is to provide a paper sheet feeding-out control device capable of performing the above.

(D) Structure of the Invention This invention is summarized. When a paper sheet is detected as an abnormal approaching paper sheet which is drawn out by approaching a certain distance or less, the latter paper sheet is drawn out and the paper sheet is drawn out. Stop, or when an overlap feed is detected in which two or more paper sheets are overlapped and fed out, the overlapped paper sheet is fed out, then the next one sheet is fed out, and then the paper sheet feeding is stopped. And the feeding stop means for stopping the feeding of the paper sheets by the feeding stop means, after the paper sheets that are abnormally close to the back of the paper sheets or the frontmost paper sheet of the overlapping paper sheets. Transport monitoring stop means for stopping the transport monitoring for the paper sheet of (1), and whether or not the paper sheet whose transport monitoring is stopped by the transport monitoring stopping means disappears from the transport path, and when it is determined that there is no paper sheet Feeding to start feeding And starting means.

(E) Embodiment FIG. 2 is a schematic configuration diagram of a bill feeding control device according to an embodiment of the present invention.

The banknote payout control device of the present embodiment includes a banknote payout unit 1,
The discriminating unit 2, the normal bill store unit 3, and the abnormal bill store unit 4 are included. Banknotes are accumulated and stored in the banknote payout unit 1. The feeding roller CL1 feeds the bills from the bill feeding unit 1 to the conveying path R1 one by one at a predetermined interval. Transport path
The discriminating unit 2 provided in R1 discriminates the authenticity of the bills fed from the bill feeding unit 1. The normal bill store unit 3 stores the bills determined to be normal. The abnormal bill store unit 4 collects the bill determined to be abnormal. The banknotes that have passed the discriminating unit 2 are sorted by the sorting flapper FP to the transport path R2 or R3. The normal bills are stored in the normal bill store unit 3 through the conveyance path R2, and the abnormal bills are collected in the abnormal bill store unit 4 through the conveyance path R3. The sensor S0 provided in the bill payout unit 1 detects the stored bills. Feeding roller CL1
The sensor S1 provided in the vicinity of detects the feeding of one bill by the passage of the bill. The sensor S2 provided at the distribution point to the transport path R2 or R3 detects that the bill has reached the distribution point due to passage of the bill. Sensors S3 and S4 provided at the entrances of the normal bill store unit 3 and the abnormal bill store unit 4 detect that a bill has been conveyed to the normal bill store unit 3 side or the abnormal bill store unit 4 side. The sorting flapper FP moves to the side that opens the conveyance path R2 when the solenoid SL1 (not shown) is turned on, and the conveyance path R3 when the solenoid SL2 (not shown) is turned on.
Move to the open side. The banknotes are transported on the transport paths R1 to R3 by a known transport device including a transport belt. The amount of movement of the bill moving along the transport path is detected by counting the number of pulses generated by a tachogenerator (not shown) connected to the drive unit of the transport system.

FIG. 3 shows a schematic configuration of the control system. The control unit 5 is composed of a microprocessor, and the ROM in the control unit 5
A bill payout processing program is stored in.
The sensor interrupt circuit 6 gives the controller 5 a sensor interrupt signal corresponding to the outputs of the sensors S0 to S4. The tachogenerator interrupt circuit 7 outputs an interrupt execution command such as a count process for discrimination by the discrimination unit 2 and conveyance monitoring at the rising timing of a pulse generated by the tachogenerator (hereinafter, this pulse is referred to as a TG pulse). The flapper control circuit 8 turns on / off the solenoids SL1 and SL2 to control the distribution operation of the distribution flapper FP. The discrimination result memory 9 stores the discrimination result by the discrimination unit 2.

Reference numerals 10 to 19 represent areas of counters and pointers assigned to the memory. The S1 counter 10 counts the number of times the sensor S1 is turned on, that is, the number of bills fed from the bill feeding unit 1. The S2 counter 11 counts the number of times the sensor S2 is turned on, that is, the number of bills that have reached the sorting point. The S3 counter 12 counts the number of normal banknotes that have passed through the sensor S3. The S4 counter 13 counts the number of abnormal bills (including abnormal payout bills) that have passed through the sensor S4.

The take-out pointer 14 stores the payout order from the paper money payout start for the first paper money of the abnormally paid-out paper money. As shown in FIG. 1 (B), at the time of abnormal approach feeding, the feeding order of the bill C1 'is stored in this pointer. Further, as shown in FIG. 1 (C), in the case of stacking two sheets, the stacking order of the banknote C1 ″ is stored. When two or more stacks are stacked in this manner, the stacked two stacks are treated as one stack and the stacking order is determined. The abnormal bill take-out ponter 15 stores the recovery order of the abnormal bills to the abnormal bill store section 4 when the abnormally fed bills are sorted to the conveyance path R3 side. The collection order for the first bill of the minute is stored.The end counter 16 is a counter that counts down by "1" each time a TG pulse is generated when the operation of the feeding roller CL1 is stopped. The counter is set in advance as a start value with a value corresponding to the elapsed time from when the feeding roller CL1 is turned off until there are no bills in the conveyance path. .

The inter-notebook counter 17 is for counting the TG pulse and checking the interval or the bill length between the bills fed from the bill feeding unit 1. When the count value of this counter is smaller than the preset inter-card abnormal value, it is determined that the abnormal approach is being extended. Further, when the count value reaches a preset bill length abnormal value, it is determined that two or more cards have been taken out in an overlapping manner.

18 is between sensor S1 and S2, between sensor S2 and S3 and between sensor S2
It is a TG counter for monitoring the bill conveyance in each conveyance path between S4. That is, a jam check is performed by this TG counter. This counter counts up each time a TG pulse is generated. It is judged that a jam has occurred when the count value of each TG counter reaches a jam value set in advance for each transport path without the banknotes having passed through each transport path in the above section. The jam value between the sensors S1 and S2 is set to a value slightly larger than the moving amount (time) until the bill passes the sensor S1 and reaches the sensor S2. Sensor S2
The jam value between the sensor and the sensor S3 is set to a value slightly larger than the moving amount (time) until the bill passes through the sensor S2 and reaches the sensor S3. Similarly, the jam value between the sensors S2 and S4 is set to a value slightly larger than the movement amount (time) from reaching the sensors S2 to S3.

Reference numeral 19 is an abnormal bill counter for counting the number of abnormal bills to be distributed to the abnormal bill store section 4 (including bills at the time of feeding abnormality).

Next, a specific operation of the bill payout process will be described with reference to FIG.
This will be described with reference to the flowchart of (D).

At step n1 (hereinafter, step ni is simply referred to as ni), the counters and the data area of the memory are cleared. Then, the feeding roller CL1 is turned on to start bill feeding (n2). When a bill is fed from the bill feeding unit 1, the sensor S1 is turned on, and the S1 counter 10
Increases by "1" (n3, n4). Furthermore, from n4 through n5, n6
The process proceeds to n7, where the bill interval counter 17 is cleared and then counting is started (n8), and at the same time, conveyance monitoring between the sensors S1 and S2 is started (n9). The jam check between the sensors S1 and S2 is executed by the TG counter for monitoring S1 and S2 (n4
7). The counting process of the bill interval counter 17 is executed by an interrupt process every time a TG pulse is generated (n40 to n42).

Next, the processing at the time of normal feeding will be described. The sensor S1 is turned on every time the bills are sequentially fed, but when the bills are normally fed at a certain interval, the count value of the inter-payment counter 17 indicates that the bills will be billed before the next bill is fed. Since it exceeds the abnormal value for the time period and does not reach the abnormal value for the bill length (n
6, n43), and the take-out pointer 14 remains "0" (n
Five). The bill that has passed the sensor S1 is conveyed to the discrimination section 2 and discriminated (n37). This discrimination is executed by interruption processing, and the discrimination result is stored in the discrimination result memory 9 (n38). When the bill passes through the discrimination section 2 and is conveyed to the sorting point, the sensor S2 is turned on (n15). S2 for n16
Increase the counter 11 by "1". Then, it is determined in n17 whether the take-out pointer 14 is "0", and further, the discrimination result of the bill that has come to the distribution point is read to determine whether it is a normal bill (n18, n19). Sensor S2-S for normal bills
Start transport monitoring between 3 (n20). This sensor S2
The jam check between S3 and S3 is executed by the S2 to S3 monitoring TG counter (n48). Then, the solenoid SL1 is turned on to move the sorting flapper FP to the side where the transport path R2 is opened to sort the normal bills to the normal bill store unit 3 side (n21). When the normal bills are conveyed to the normal bill store unit 3 and the sensor S3 is turned on, the S3 counter 12 is incremented by "1" to finish the conveyance monitoring between the sensors S2 and S3 (n30 to n32). On the other hand, in the case of an abnormal bill, the sensor S2-
Start transport monitoring between S4 (n19 → n22, n28). The jam check between the sensors S2-S4 is executed by the S2-S4 monitoring TG counter (n49). Then, in this case, the solenoid SL2 is turned on to move the sorting flapper FP to the side where the conveyance path R3 is opened to sort the abnormal bill to the abnormal bill store unit 4 side (n29). When the abnormal bill is conveyed to the abnormal bill store unit 4 and the sensor S4 is turned on, the S4 counter 13 is incremented by "1" to finish the conveyance monitoring between the sensors S2 and S4 (n33, n34, n3).
6). As described above, regardless of the discrimination result, the fed-out bills are monitored one by one while being conveyed from being fed out to being stored.

Next, the processing when the abnormal approaching extension shown in FIG. 1 (B) occurs will be described. In this case, when the succeeding banknote C2 ′ is fed out, the bill interval count value counted from the time when the preceding banknote C1 ′ is dispensed is smaller than the bill interval abnormal value (n6), so that the take-out pointer 14 (S1 The value of the counter-1) is set (n11). That is, the payout order of the previous bill C1 'is set. Then, the feeding roller CL1 is turned off to stop the bill feeding, the inter-payment counter 17 is cleared, and the end counter 16 is started (n12 to n14).

At the time of such an abnormal extension, the S2 counter 11 is incremented by "1" at n16, and then the count value of the S2 counter 11 and the set value of the take-out pointer 14 are compared and judged (n16, n17, n23,
n24). Since the count value of the S2 counter 11 is smaller than the set value of the take-out pointer 14 until the banknote C1 'reaches the sorting point, the process proceeds from n23 to n18 and the above-mentioned sorting process is executed. When the bill C1 'reaches the sorting point, the S2 counter
The count value of 11 coincides with the set value of the take-out pointer 14 (n24), the abnormal bill counter 19 is incremented by "1", and the count value (collection order) for the bill C1 'is set in the abnormal bill take-out pointer 15 ( n25, n26). Then, in this case, the conveyance monitoring between the sensors S1 and S2 is ended (n27). As a result, the sensors S1-S for the subsequent banknote C2 '
There is no monitoring between the two. Since the monitoring of the bill C2 'is stopped in this way, as shown in FIG. 1 (B), the rear bill C2' overlaps the front bill C1 'between the sensors S1 and S2 and the sensor S2 It is possible to prevent the occurrence of a jam even if the number of times of ON does not match the number of delivered sheets. In other words, if this is not done, when the banknotes C1 'and C2' overlap and the sensor S2 is turned on, it will not be possible to confirm that the banknote C2 'has reached the sorting point, and it will be determined that a jam has occurred. become.

After monitoring between the sensors S1 and S2 is completed, the sensor S2
-Transfer monitoring between S4 and start solenoid
SL2 is turned on and banknote C1 'is sorted to the abnormal bill store unit 4 side (n28, n29). When the bill C2 'reaches the sorting point without overlapping the bill C1' (n24), it is sorted to the abnormal bill store unit 4 side (n29). When the bill C1 'is conveyed to the abnormal bill store unit 4, the conveyance monitoring between the sensors S2-S4 is ended (n33 to n36). This is also for the same reason as the end of monitoring in n27, and the sensor S2-S4 for the banknote C2 '
By stopping the monitoring during the period, it is possible to prevent the occurrence of a jam when the bills C1 'and C2' overlap between the sensors S2-S4. The later banknote C2 'is the previous banknote C1'
Since the count value of the S4 counter 13 exceeds the set value of the abnormal bill take-out pointer 15 when it is conveyed to the abnormal bill store unit 4 without overlapping with, the process proceeds to n34 → n35 → n39 → n37.

Next, a process when the two-sheet feeding out shown in FIG. 1 (C) occurs will be described. In this case, the bill-to-bills count value reaches the bill length abnormal value by the time the bills C2 ″, which are superposed on the preceding bill C1 ″, have passed through the sensor S1 (n41 to n4).
Four). Therefore, the take-out pointer 14 is set with the count value of the S1 counter 10, that is, the payout order of the preceding banknote C1 ″ among the overlapping banknotes, and the inter-payment counter 17 is cleared (n4
5, n46). When such a double stack occurs, another banknote is unrolled after the overlapping banknote is unrolled (n3
~ N5). This is because the possibility that the next banknote will also be abnormally fed out when the feeding abnormality is normally caused by stacking two sheets is also collected in the abnormal bill store unit 4. After the trailing edge of the banknote C2 ″ after the overlapping banknote has finished passing through the sensor S1, another banknote is unrolled, and then the unrolling roller CL
Turn off 1 to stop bill feeding (n12). When the banknotes C1 ″ and C2 ″ reach the sorting point while overlapping, S2
Since the count value of the counter 11 matches the set value of the take-out pointer 14 (n17, n23, n24), the double-fed banknote is distributed to the abnormal bill store section 4 side (n25 to n29). in this case
At n27, the conveyance monitoring between the sensors S1 and S2 for the one bill finally fed out is stopped. This is because it is not necessary to monitor the above-mentioned section, since the bill paid out last is simply collected. When the last bill reaches the distribution point, the process proceeds from n24 to n29, and the bill is distributed to the abnormal bill store unit 4 side and collected. For the last bill, the sensor
Transport monitoring between S2-S4 is also stopped. This is also for the same reason as above.

As shown in FIG. 1 (C) during the above-mentioned overlap feeding, the banknotes C1 ″ and C2 ″ that are overlapped may be separated during the transportation, and in this case, the banknote C2 ″ and the last banknote The previous banknote C1 ″ to stop the transport monitoring for
Comes to the sorting point, the conveyance monitoring between the sensors S1 and S2 is ended (n24 to n27), and the bill C1 ″ is stored in the abnormal bill store unit 4
When collected, the conveyance monitoring between the sensors S2-S4 is ended (n33 to n36), and the conveyance monitoring between the sensors S2-S3 and the sensors S2-S4 is not started for the subsequent bills. As a result, the count values do not match in the above section, so that it is possible to prevent the middle banknote C2 ″ and the last banknote from determining that a jam has occurred.

When the feeding roller CL1 is once turned off when the above-mentioned abnormal feeding occurs (n12), or when the sensor S0 is turned off and there is no stored bill and the feeding roller CL1 is turned off (n12).
10, n12), end counter after clearing the bill counter 17
Start 16 (n13,14). The counting process of the end counter 16 is executed at n50 to n52. When the end counter 16 counts down from the start value and becomes “0”, it is determined that there are no banknotes in the transport path (n5
2). Next, it is judged whether or not the take-out pointer 14 is "0" (n53), and when it is "0", it is determined that the conveyance of all banknotes has been completed without abnormal feeding and the processing at the time of completion of conveyance is performed. Go and end (n55). When the take-out pointer 14 is not set to "0" (n53),
Whether or not the feeding is interrupted due to an abnormal feeding is judged by turning on / off the sensor S0 (n54). When the sensor S0 is off, it is determined that the transportation of all banknotes is completed, and the process ends (n54, n55). When the sensor S0 is on, it means that there are still banknotes left in the banknote payout section 1, and the banknotes remaining in the transport path are checked and the counters and pointers are cleared to restart the banknote payout ( n54 to n57 → n
2).

As described above, the conveyance is monitored only for the first banknotes (banknotes C1 ′, C1 ″ in FIGS. 1 (B) and (C) of the abnormally extended portion, and the rear banknotes are not monitored. In addition, the abnormal payout is collected in the abnormal bill store unit 4 and then the payout is restarted. Therefore, it is possible to prevent the abnormal payout from being treated as a jam processing target, and thereby, the jam processing by the abnormal payout is performed. The jam rate is greatly reduced by eliminating the problem, and by restarting the feeding operation immediately after collecting the abnormal feeding amount, there is no waste of stopping the device for the jam processing due to the abnormal feeding amount, and the operating rate can be improved. it can.

Of the above steps, n5, n6, n11, n12, n43, n44 is the feeding stop means of the present invention, n24, n27, n36, n39 is the transfer monitoring stop means of the present invention, and n50 to n54 and n2 are the book. They correspond to the feeding start means of the invention.

(F) Effects of the Invention As described above, according to the present invention, when the paper sheets are fed out abnormally close to each other, or when two or more sheets are fed out, the paper sheets are respectively placed behind the earliest paper sheet. Of paper sheets (especially in the latter case, including the paper sheet that is fed next to the overlapping portion) is stopped to prevent the occurrence of jam due to abnormal feeding before it is judged to have occurred due to abnormal feeding. The jam rate can be significantly reduced, and the feeding rate of paper sheets can be restarted when there are no more paper sheets in the conveyance path after the above-mentioned conveyance monitoring is stopped. Can be improved.
