Abstract

PURPOSE:To reduce the occurrence of a paper jam as well as to improve the rate of operation in a transaction processing device, by discriminating a conveying form of bank notes immediately after being delivered from a delivering device, while discharging abnormal notes at onece in time of trouble happening in the conveying form. CONSTITUTION:A delivery sensor 5 detects the bank note delivered at first, and if a counting value of length counter is larger than setting value, it is stored in memory as being a chain note. Next, when the second note is delivered out of a delivery roller 3, the sensor 5 detects it, and counts clock pulses in number equivalent to a priod till the second note is detected from the first one detected, and if the counting value is smaller than the setting value, it is stored in memory to be an abnormal note as judging it a drag note. And, the first note being discriminted in its length is conveyed along a conveying route 4, then a skew sensor 6 detects the note, and when a skew note is the case, one side of two sensors first detects it, storing it as an abnormal note at a time when a counting value of a skew counter is more than the setting value, thus a distributing flapper 8 distributes a portion of abnormal notes to the side of a return port 10.

Description

[Detailed Description of the Invention] Technical Field of the Invention The present invention relates to an abnormal banknote processing device, and in particular, it is installed in automatic teller machines (ArM), automatic cash dispensers (CD), etc. It is attached to an abnormal banknote processing device that removes banknotes with abnormalities such as chain holes.

Description of the Prior Art ATMs, CDs, etc. installed in financial institutions such as banks have a built-in banknote transport device for transporting banknotes one by one. They are transported sequentially at regular intervals. However, the transported banknotes include a mixture of new banknotes that have never been used excessively and banknotes that have wrinkles due to frequent use. For this reason, when these banknotes are fed out one by one, the intervals between them are not constant, resulting in so-called unrolled banknotes in which the intervals between banknotes are extremely short, or parts of the banknotes are separated. In some cases, the banknotes may overlap, resulting in so-called chain banknotes, or in other cases, the banknotes may become so-called skew banknotes, in which the banknotes are tilted by an angle formed with respect to the conveyance direction. Such banknotes are generally called abnormal banknotes. Normally, the banknote conveyance path of ATMs, CDs, etc. is relatively long, so when the above-mentioned abnormal banknotes are conveyed, there is a high incidence of jams along the conveyance path, and the transaction processing equipment often has to be stopped. It had the disadvantage of causing

OBJECTS OF THE INVENTION Therefore, the main object of the present invention is to provide an abnormal banknote processing apparatus that immediately removes and waits for an abnormal banknote when it is detected on a banknote conveyance path. It is.

Structure and Effects of the Invention To summarize the present invention, when the mode of conveyance of banknotes immediately after being dispensed from the dispensing means is identified, and it is identified that an abnormality has occurred in the mode of conveyance, the banknote in which the abnormality has occurred is It is configured to be discharged immediately.

Therefore, according to the present invention, abnormal banknotes such as skewed bills, dangling bills, and chain holes can be removed from the middle of the conveyance path, so the jam occurrence rate can be extremely reduced even when the banknotes have a long conveyance path. , the operating efficiency of transaction processing devices, etc. can be improved.

The present invention will be explained in more detail below along with embodiments shown in the drawings.

DESCRIPTION OF THE EMBODIMENTS FIG. 1 is a diagram showing a bill conveyance mechanism according to an embodiment of the present invention. In FIG. 1, banknotes are inserted into a banknote inlet 2 of a banknote conveyance station 1. As shown in FIG.

FIG. 3 is a diagram showing a normal banknote conveyance mode, and FIGS. 4 to F6 are diagrams showing abnormal banknote conveyance configurations. In particular, FIG. Figure 6 shows the case of a chain hole; 7th
8 and 8 are flowcharts for explaining the specific operation of an embodiment of the present invention, in particular, FIG. 7 shows the main routine, and FIG. 8 shows the interrupt processing routine.

Next, referring to FIGS. 1 to 8, a detailed operation of an embodiment of the present invention will be described. When the CPU 21 receives the feeding command, it proceeds to the main routine shown in FIG. In the illustration, the step is abbreviated as SP>S
At Pl, it is determined that there is a feeding command, and at step SP2, a control signal for turning on the clutch provided in relation to the feeding roller 3 is given to the clutch control circuit 25. When the clutch is turned on, the feeding roller 3 rotates, and the banknotes that have been inserted into the banknote slot 2 are sequentially fed out one by one onto the conveyance path 4. A sensor (not shown) for detecting the remaining banknotes in the banknote slot 2
is provided, and based on the detection output of this sensor,
The CPU 21 determines whether there are any banknotes left in step SP3. If there are banknotes left, feed roller 3
The banknotes are fed out one by one in sequence. When there are no more bills left in the bill slot 2, the clutch is turned off in step SP4.

During the series of operations described above, the payout sensor 5 first detects the first paid bill.

Based on the detection output of the feeding sensor 5, the sensor interrupt circuit VR22 provides an interrupt signal to the CPU21.

Then, the CPU 21 jumps to the interrupt processing routine shown in FIG. In the interrupt processing routine, step SP5
At this point, it is determined whether an interrupt signal from the feeding sensor 5 has been input. When it is determined that the banknote has been input, it is determined in step SP6 whether or not it is the first bill. If it is the first bill, the interval counter 29 and the length counter 30 start counting in step SPI 1 without performing the determination as to whether it is a normal bill in step 5pio.

After receiving the interrupt signal from the feeding sensor 5, the CPU 21 determines in step SPI 2 that the feeding sensor 5 is off, that is, that no interrupt signal indicating that it is detecting banknotes has been input, and then proceeds to step SPI 7. In step 5P20, it is determined that the skew sensor 6 is not on, and in step 5P26, it is determined that the distribution sensor 7 is not on. And step 5P
At step 30, it is determined whether or not a clock pulse is input from the tacho generator 23. If the clock pulse is manually generated, the interval counter 29 is counted up in step SP31, and the length counter is counted up in step 5P32. However, in step 5P33, since the skew counter 31 has not started counting, the process returns to the main routine without incrementing the skew counter 31. Therefore, after the first bill is dispensed and the dispense sensor 5 detects the bill, the interval counter 29 and the length counter 30 are counted up based on the clock pulse from the tacho generator 23. When the first bill is dispensed and passes the dispense sensor 5, the dispense sensor 5 no longer detects the bill, and the sensor interrupt circuit 22 outputs an interrupt signal indicating that the bill has not been detected. The CPU 21 determines in step SP12 that the feeding sensor 5 no longer detects a banknote. And step S
At P13, the count value of the length counter 30 is read. In step SP14, the CPtJ21 compares the count value of the length counter 30 with a preset value to determine the length of the banknote. That is, it is determined whether the count value of the length counter 30 is larger than the value corresponding to the width of the banknote shown in FIG. If the counted value of the length counter 30 is larger than the set value (if
It is determined that the banknotes are so-called consecutive FIRIA banknotes in which parts of the banknotes overlap, and the banknotes are stored as abnormal banknotes in step SP15. However, if the count value of the length counter 30 is equal to the set value, it is determined that the dispensed banknote is one banknote, and it is stored as a normal banknote in step SP16.

On the other hand, the feeding roller 3 feeds out the second banknote. When the second bill is dispensed, the dispense sensor 5 detects the bill and an interrupt signal is given to the CPIJ 21. C.P.
U21 determines in step SP5 that the feeding sensor 5 has detected a banknote. Then, in step SP6, the CPU 21 determines that it is not the first bill, and reads the count value of the interval counter 29 in step SP7. At this time, the interval counter 29 counts the number of clock pulses corresponding to the period from detecting the first bill to detecting the second bill. Then, in step SP8, the CPtJ21 compares the count value of the interval counter 29 with the set value. That is, if the count +111f of the interval counter 29 is small, it is determined that the interval between the bills shown in FIG. 3 is narrow and the bills are drawn out as shown in FIG. 4. and,
If there is an out-of-date banknote C, the second banknote is stored as an abnormal banknote in step SP9. However, in step SP8, if the count value of the interval counter 29 is equal to or larger than the set value, the J
3 and remember that it is a normal banknote.

By the way, the first banknote whose length has been determined as described above is conveyed along the conveyance path 4, and the skew sensor 6 detects the banknote. As shown in FIG. 6, the skew sensor 6 is composed of two sensors 61 and 62 arranged in a direction perpendicular to the conveyance path 4 and with an interval narrower than the length of the banknote. When the banknote is being conveyed in parallel to the direction perpendicular to the conveyance path 4, the two sensors 61 and 62 detect the banknote at the same time. However, when a banknote is conveyed at an angle with respect to the direction perpendicular to the conveyance path 4, resulting in a so-called skewed banknote, one of the sensors 61 and 62 detects the banknote first, and The other sensor will detect the bill later.

For example, as shown in FIG. 6, when the sensor 61 detects a banknote first, the sensor 61 detects a banknote in step SP17.
It is determined that an interrupt signal from
If the sensor 62 does not detect a banknote at pi s, the skew counter 31 starts counting in step 5P19.

Then, step SP5. SPI 2. SPI 7゜5
P20, 5P26J5J: and 5P30 (7) 51El process '1 line, and when a clock pulse is input from the tacho generator 23 in step 5P30, the stencil S
P33 Smell counter 31 is incremented by 1. After that, when Sen + 162 detects a banknote, it is determined in Step 5P20 that an interrupt signal from Senna 62 has been input manually, and Step S P 2 'I smell - (The sensor 61 detects the banknote - ( determines that there is a banknote, and reads the counted value of the skew counter 331 in step 5P22. In step 5P23, the CPLJ 21 reads the sugar value of the skew counter 31 and the preset value. When the counted value of the skew counter 31 is smaller than the set value, that is, it is determined that the skew is large, in step S1-'24, the banknote is abnormal. It remembers that it is a banknote.However, if the RI value of the skew counter 31 is almost equal to the set value,
In step 5P25, it is determined that the banknote is a normal banknote.

As described above (by passing the position of the skew sensor 6)
,: The banknotes are further conveyed, and when the distribution sensor 7 detects the banknotes, an interrupt signal is sent to the CPU 21.

In response, the CPtJ21 determines in step 5P26 that the interrupt signal from the distribution sensor has been input, and in step 5P27 determines whether or not the banknote is an abnormal banknote. If the banknote is abnormal, a control signal for turning on the solenoid is given to the solenoid control circuit 24 in step 5P29. When the solenoid turns on,
A sorting flapper 8 sorts the abnormal banknotes to the return slot 10 side. However, if the banknote is normal, the solenoid is turned off in step 5P28, and the normal banknote is temporarily stored in the door section 9.

As described above, according to this embodiment, the banknote conveyance path 4
A feeding sensor 5, a skew sensor 6, and a sorting sensor 7 are provided in the bank, an interval counter 29 for counting the interval between banknotes fed out one by one, a length counter 30 for counting the width of banknotes, and a conveyance path 4. A skew counter 31 that counts the inclination of the banknote relative to the banknote is provided, and it is determined whether the banknote is being conveyed normally or abnormally based on the count value of each counter 29 to 31 and a preset value, If there is an abnormality, the sorting flapper 8 immediately returns the banknote to the return slot 10, so that the banknote is not conveyed in an abnormal form along a long banknote conveyance path, and the occurrence of jams can be minimized. .
