Description

[Detailed description of the invention]

The present invention relates to a paper sheet sorting device that automatically inspects paper sheets such as slips, stock certificates, checks, and securities and classifies them into valid sheets and invalid sheets. Recently, various paper sheet sorting devices have been developed and put into practical use, which automatically inspect paper sheets such as securities and classify them into valid sheets and invalid sheets. This type of sorting device can separate the number of paper sheets by 1.
It automatically counts the number of sheets and checks whether there is an excess or deficiency in the number of sheets, and at the same time detects invalid sheets, such as counterfeit notes, foreign notes, expired notes, etc. They are separated into genuine notes (those suitable for reuse) and genuine notes (those suitable for reuse), and are sealed and stamped in bundles of 100 each. However, the conventional sorting device described above performs so-called batch processing in which 1000 sheets are counted as a unit, so it is possible to determine whether there is an excess or deficiency in the number of sheets in units of 1000 sheets, and whether there are counterfeit notes. but,
It is not possible to determine whether or not an abnormality occurred in a group of 100 out of 1000 sheets. In other words, usually 100 sheets of paper such as securities are sealed with a small obi, and then 10 bundles of the 100 sheets sealed with a small obi are collected and 1000 sheets are each sealed with a large obi. are bundled. Additionally, although it is customary for all 1000 sheets of paper to be handled at the same processing location, each batch of 100 sheets is often handled by a different person. Therefore, it is conceivable that there may be a request to know which handler handled the item that had an abnormality. In other words, what used to be done in units of 1000 sheets now needs to be done in units of 100 sheets. If we process this in units of 100 bills using the same method as before, we will have to check the number of bills and process counterfeit bills every 100 bills, which increases the amount of time the device itself is not operating and reduces the processing capacity of the device. This will significantly reduce the labor-saving effect. In addition, conventional sorting devices that process in units of 100 sheets require inserting a sorting card every 100 sheets, which significantly increases the burden on the operator and is not practical. The present invention has been made in view of the above circumstances, and its purpose is to reduce the non-operation time of the device itself, to minimize the decrease in processing capacity and increase in the burden on the operator, and to reduce the amount of time the device itself is inactive, and to There is less wasted time between each unit when processing paper sheets.
Another object of the present invention is to provide a paper sheet sorting device that can efficiently process paper sheets by eliminating the burden on the operator for inserting sorting cards. The present invention will be described below with reference to an illustrated embodiment. In Fig. 1, reference numeral 1 denotes a supply section, in which paper sheets to be sorted such as securities (hereinafter simply referred to as paper sheets) are set in a standing position every 100 sheets, and when this device starts sorting, the paper sheets are The leaves are fed to the extraction device 2. The take-out device 2 sequentially takes out the sheets set in the supply section 1 one by one at predetermined intervals and supplies them to the conveying device 3, and is constituted by, for example, a vacuum suction rotor. The conveyance device 3 holds the paper sheets taken out by the takeout device 2 between a pair of conveyance belts and guides them to the sorting detection section 4 and the sorting device 5 .
The division detection section 4 is provided in the middle of the conveyance device 3, and has the following functions. That is, the first function is to accurately count the number of paper sheets being conveyed and check whether a pre-specified number of paper sheets are present. The second function is that when two or more sheets are taken out together by the take-out device 2, that is, when they are stacked, it is impossible to accurately detect and count the sheets, so the stack Detect. This detection means may use any of, for example, an optical method based on a change in the amount of light that passes through the paper sheet, or a detection method that mechanically measures the thickness of the paper sheet. The third function is
If the paper sheets taken out by the take-out device 2 are abnormally close to each other, it is impossible to accurately detect and count the sheets as described above, so that the abnormal approach is detected. This detection means detects, for example, the interval between sheets and compares the interval with a normal interval. The fourth function is to check the contents of the paper sheet being conveyed.
By examining each sheet, invalid notes (counterfeit notes, foreign notes, expired notes, and other suspicious paper sheets) and damaged notes (paper sheets unsuitable for reuse) are separated. This detection means may be any known optical method, mechanical method, or any other method as long as it is effective for achieving the intended purpose. Further, by incorporating an optical character reading device, it is possible to read predetermined information (such as a number) recorded on paper sheets and separate paper sheets with older publication years. In any case, it is constructed using one or more sets of detection devices depending on the purpose. In this case, each detection device usually detects invalid notes (unfit notes and paper sheets other than normal notes, such as counterfeit notes, different types of notes, and stacked notes), unfit notes, and normal notes (paper sheets that can be reused). This determination result is obtained for one sheet of paper. From these determination results, one determination result is finally given to one sheet of paper according to the priority order shown below.

[Table] The sorting device 5 is provided at the terminal end of the conveyance device 3, and detects whether the paper sheets conveyed by the conveyance device 3 and passed through the detection unit 4 are shifted by a sheet shift circuit described later. It is divided into the first conveyance path 6 or the second conveyance path 7 according to the determination result signal of the section 4. That is, when the detection unit 4 outputs a determination result of an invalid note, the corresponding paper sheet is guided to the second conveyance path 7, and when a determination result of a damaged note or a valid note is output, the corresponding paper sheet is guided to the first conveyance path 7.

The direction changing device 17 rotates the conveyed bundles by about 90 degrees and sends them to the bundle conveyance path 18. The bundle transport path 18 sends the bundles from the direction changing device 17 to the aligning device 19 . The collection device 19 arranges the stacked state of the paper sheets in the bundled state. Further, the bundle transport path 18 sends the bundles collected by the collection device 19 to the next bundle transport path 20. The bundle conveyance path 20 sends the arranged bundles to the sealing device 21. Sealing device 21
The bundles being transported are tied with bands to prevent them from collapsing. Further, the bundle transport path 20 sends the bundles banded by the banding device 21 to the next bundle transport path 22. The bundle transport path 22 sends the bundles to a sealing check device 23 and a stamping device 24. The sealing check device 23 checks whether the grip is securely sealed. Further, the stamping device 24 displays necessary information such as the date, operator code, and device number on the surface of the band wrapped around the handle, as well as a classification mark indicating whether the bill is a good bill or a damaged bill. and,
A bundle sorting device 25 is provided at the terminal end of the bundle conveyance path 22. The stack sorting device 25 selects a stack stacking section (not shown) to stack the bills depending on whether the bills are good or unfit. The direction changing device 17, the procurement device 19, the sealing device 21, the stamping device 24, and the bundle sorting device 25 are each controlled by signals from a bundle shift circuit, which will be described later. On the other hand, the terminal end of the second transport path 7 is located near the supply section 1, and an invalid ticket stacking device 26 is provided at the terminal end. This accumulating device 26
The system sequentially stacks the invalid tickets and stacked tickets conveyed on the second conveyance path 7 in a collection box, and when a predetermined number of tickets have been sorted, a separate box is used to stack the invalid tickets and stacked tickets for the next category. The stacking box is moved, and the sheets are separated into predetermined numbers and brought to the operator's hand. The above-mentioned accumulation device 26

A display 80 (described later) that displays the numerical value entered with the numeric keypad 75, a display 77 (described later) that displays the predetermined number of invalid tickets and stacked tickets that the operator is processing, and a display 77 (described later) of the printer 48. It consists of a receipt outlet, a paper sheet outlet of the invalid ticket accumulating device 26, etc. Then, the printer 4
8, when there is an excess or deficiency in a predetermined number of sheets, the number of excess or deficiency and the predetermined number of sheets in which the excess or deficiency falls are printed on the receipt. Next, the counting circuit used in this device will be explained. This counting circuit calculates the correct bill accumulating portions 11 ₁ , 11 ₂ and the unfit bill accumulating portions 13 1 , 13 ₁ ,
13 Count the number of paper sheets accumulated in ₂ ,
It is a circuit that temporarily records the number of tickets and compares the sum of the number of tickets and the number of invalid tickets and stacked tickets inputted from the key input device 47 with a set value H which is a specific number (for example, 100 tickets), For example, it is configured as shown in FIG. That is, assuming that the number of paper sheets to be supplied now is the same value as the set value H, the invalid bill stacking device 26 and the valid bill stacking unit 11 ₁ , 1
The sum of the number of paper sheets that are separately stacked in the ₁₂ unfit note stacking sections 13 ₁ and 13 ₂ is H sheets. The output of the detection circuit 51 connected to the detector 34 is supplied to the total number counters 53 ₁ and 53 ₂ via AND circuits 52 ₁ and 52 ₂ , respectively, and is also connected to the detector 35. Detection circuit 5
The outputs of 4 are supplied to total number counters 56 ₁ and 56 ₂ via AND circuits 55 ₁ and 55 ₂ , respectively.
Furthermore, a detection circuit 57 connected to the detector 36
The outputs are supplied to total number counters 59 ₁ and 59 ₂ via AND circuits 58 ₁ and 58 ₂ , respectively.
On the other hand, a detection circuit 60 connected to the detector 28
The output of is supplied to the timing signal generation circuit 61. Predetermined timing signals are supplied from this timing signal generation circuit 61 to count control circuits 62, 63, and 64, respectively, and these control circuits 6
2, 63, 64, the counters 53 ₁ , 5
AND circuits 52 ₁ , 52 ₂ , 6 1 , 59 ₁ and counters 53 _{2 , 56 2 , 59 2 operate alternately} .
55 ₁ , 55 ₂ , 58 ₁ , and 58 ₂ are controlled respectively. Then, after a certain period of time has elapsed since the detector 28 detects that all the predetermined number H of sheets have been taken out and disappeared, the contents of the counters 56 ₁ , 56 ₂ and the counters 59 ₁ , 59 ₂ are transferred to the gate circuit 65 . are supplied to an adder 66 for addition, and the addition result is supplied to a comparator 67. Also, this comparator 67
The contents of the counters 53 ₁ and 53 ₂ are supplied via the gate circuit 68 and compared with the output of the adder 66 . As a result of this comparison, if the two do not match, the device is in an abnormal state, and therefore, in this case, the mismatch indicator 69 displays a mismatch. On the other hand, if the results of the above matching match, the arithmetic circuit 70 uses the counters 53 ₁ , 53 ₂
The difference between the contents of and the set value H is determined, and the result is stored in the storage device 71. Note that the gate circuits 65 and 68 are controlled by a verification control circuit 72 that operates in accordance with the output of the timing signal generation circuit 61. Further, the timing signal from the timing signal generation circuit 61 is supplied to the counter 74 via the count control circuit 73, so that the counter 74 counts the predetermined number of sheets that have been sorted, and performs the count. The contents are stored in the storage device 71 together with the result of the arithmetic circuit 70. In the arithmetic circuit 70, the counter 5
Calculating the difference between the contents of 3 ₁ and 53 ₂ and the set value H and storing the result in the storage device 71 is performed when the detector 28 detects that the predetermined number of sheets have been taken out. After that, it is performed every time a predetermined period of time elapses. In this case, two sets of counters, namely 53 ₁ , 56 ₁ , 59 ₁ and 53 ₂ , 56 ₂ , 59 ₂
Since the paper is used, verification is performed automatically without stopping the conveyance of paper sheets. Here, the details of the storage device 71 will be explained in the third section.
This will be explained with a diagram. That is, the storage device 71 stores, for example, addresses 1 to n and addresses n+1 to n.
It has memory addresses up to +7. and,
From addresses 1 to n, the contents of the counter 74 (bundle number) indicating which predetermined number of sheets have been sorted, as well as the correct bill stacking sections 11 ₁ , 11 ₂ and the unfit bill stacking section 13 ₁ , 13 ₂ The contents of the counters 53 ₁ , 53 ₂ and the set value H
The difference, that is, the result of the arithmetic circuit 70, is stored in correspondence with each other. When the first (first) predetermined number of sheets is divided, the numerical value [1] representing the first predetermined number of sheets is stored at address 1 and the result Q ₁ of the arithmetic circuit 70 at that time, and the second When the division of the predetermined number of sheets is completed, the numerical value [2] representing the second division of the predetermined number of sheets and the result X2 of the calculation circuit 70 at that time are stored at address 2. When the storage up to address n is completed in this way, the process returns to address 1 and stores the numerical value [n+1] representing the n+1th predetermined number of sheets at address 1 and the result Q _{o+1 of the arithmetic circuit 70} at that time. Clears and stores the previous memory contents. Until this n+1st memory is needed,
The first memory content (calculation result) is compared with the sum of the numbers of invalid tickets and stacked tickets input using the numeric keypad 75 and the comparator 76, and the first memory is no longer necessary. Thereafter, data from addresses n+2 onwards are sequentially stored starting from address 2 in the same manner as described above. Note that the storage capacity up to address n is large enough to cover the time difference between sorting good and unfit notes and checking with the numeric keypad 75, so there is no need to stop the sorting operation of this device. There is. On the other hand, at address n+1, the predetermined number of sheets that are being checked using the numeric keypad 75 is stored (the bundle number);
The contents are displayed on a display 77. That is, in this case, for example, when the number of invalid tickets and stacked tickets for the first (first) predetermined number is input using the numeric keypad 75, the number [1] is stored in the address n+1, and from then on, the next predetermined number of tickets is input. n each time the number of invalid tickets and stacked tickets is entered.
[1] is added to the contents of address +1. Also, at addresses n+2, n+3, and n+4,
The sum of the number of invalid tickets and stacked tickets input using the numeric keypad 75, the number of tickets re-entered due to an input error, and the total number of invalid tickets and stacked tickets up to the previous batch are stored, respectively. Similarly, n+5, n+6, n+
Address 7 stores the number of input invalid tickets, the number of invalid tickets re-inputted, and the total number of invalid tickets up to the previous time. Thus, the number of invalid tickets and stacked tickets entered using the numeric keypad 75 is supplied to the comparator 76 via the input control circuit 78 and also supplied to the storage device 71, thereby performing the above-mentioned storage. . When the number of sheets is input in this way, the storage device 71
is the same number as the contents of address n+1 from address 1 to n
The comparator 76 selects one of the addresses and reads out the calculation result stored corresponding to the selected number.
supply to. The comparator 76 performs count verification by comparing the calculation result supplied from the storage device 71 with the number of invalid tickets and duplicate tickets that have already been input. As a result of this verification, if there is no excess or deficiency in the number of tickets, the number of invalid tickets and stacked tickets for the next predetermined number of tickets is input using the ten keys 75. When this number of sheets is input, the storage device 71 adds the contents of addresses n+3 and n+6 to the contents of addresses n+4 and n+7, respectively, and adds the results of each addition again to the contents of addresses n+4 and n+7.
Each is memorized at address +7. At this time, the storage device 71 adds [1] to the contents of address n+1 and stores it, and also sets the sum of the input invalid tickets and stacked tickets and the number of invalid tickets to n+2,
Each is stored at address n+5 and the above operation is repeated. On the other hand, as a result of the comparison in the comparator 76,
If there is an excess or deficiency in the number of sheets, this is displayed on a display (not shown), and the key input lock circuit 79 operates to electrically lock the key input device 47. At this time, the numerical value (number of tickets) entered using the numeric keypad 75 is displayed on the display 80, so that the operator can visually check the entered numerical value and the number of invalid tickets and stacked tickets.
If you made a mistake, enter the correct number again. This re-input number of sheets is supplied to the comparator 76, and is again compared and verified with the calculation result. As a result of this comparison, if the two match, the printer 48
operates, and the contents of address n+1 of the storage device 71 (the number of the handle), the numerical value entered with the numeric keypad 75, that is, n
The contents of address +2 and the re-entered numerical value, that is, the contents of address n+3, are printed and the printed receipt is discharged. In addition, if there is no mistake in the number of sheets entered previously, and if there is a discrepancy and excess or deficiency even after re-input, when the supervisor unlocks the key input device 47 that is in the locked state, the printer 48 operates, n+1 and n+2 of the storage device 71
Then, the contents of address n+6 and the contents of comparator 76 are printed respectively. Also, if there is an invalid ticket on the numeric keypad 75, the numerical value

If a value other than [0] is entered, the key input device 47 will also be locked, and when the supervisor releases this lock state, n+1 and n+6 will be locked.
Printing the contents of each address is the same as when there is an excess or deficiency in the count. Further, after all the sorting operations are completed and the count verification by inputting from the numeric keypad 75 is also completed, by pressing the end button (not shown), the printer 48 is operated and the data stored at addresses n+1, n+4, and n+7 of the storage device 71 are pressed. The contents, that is, the number of predetermined number of sheets (number of bundles) that have been sorted, the total number of invalid tickets and stacked tickets, and the total number of invalid tickets are printed respectively. This printing allows the operator to reconfirm the number of invalid tickets and stacked tickets. Next, a method for checking the number of sheets sorted and stacked in each stacking section will be explained. The detector 35
When the contents of the valid bill sorting counter 81, which is counted by obtaining a signal from Then, the sorting device 12 is driven, and the transported paper sheets are sorted and stacked in the other genuine bill stacking section. For example, if the sorting device 12 is switched so that 100 bills are first stacked in the first genuine bill stacking section 11 ₁ and then stacked in the second genuine bill stacking section 11 ₂ , then one of the counters 85 and 86 is stacked. A comparator 88 compares the contents of the counter 85 selected by the control circuit 83 via the gate circuit 87 with the set value D. As a result of this comparison, if the two match, the integrated control circuit 89 and drive circuit ₉₀₁ immediately
The genuine bill stacking section 11 ₁ is driven, and a bundle of 100 sheets is carried out. Here, the operations of the comparator 88 and the control circuit 89 are performed in response to a predetermined timing signal output from a timing signal generation circuit 91 which operates in accordance with the output of the comparator 82. Further, at the same time as the 100 bundles are carried out, the regular bill stack counter 92 is incremented by [+100] at the time when the operation of the first regular bill stacking section ₁₁₁ is completed. On the other hand, if the result of the comparison in the comparator 88 is that the two do not match, the erroneous classification indicator 93 is activated and the apparatus enters an abnormal state. Here, the counters 85 and 86 are
a detection circuit 9 connected to the detectors 37 and 38;
By supplying each output of 4 and 95, each count operation is performed. Further, the control circuit 83
is designed to control an integrated selection circuit 96, and this selection circuit 96 controls the drive circuits 90 ₁ ,
90 ₂ is selected. Further, the selection circuit 96 is
The counters 85 and 86 are selected via the gate circuit 97, and the contents of the selected counters are sent to the comparator 98.
supply to. This comparator 98 is connected to the counter 8
Compare the contents of 1 with the contents of the counter 85 or 86, and if the two do not match, the discrepancy indicator 9 is displayed.
Activate 9. Then, the contents of the counter 85 or 86 selected by the selection circuit 96 are stored in the storage device 100. On the other hand, by similarly counting the output of the detector 36 with the unfit note sorting counter 101, the first unfit note accumulating unit 13 ₁ and the second unfit note accumulating unit 13 are sorted by the sorting device 14 in the same way as in the case of normal notes. Switching control for ₂ is performed. Similarly, the detector 39,
Detection circuits 102 and 103 are respectively connected to the detection circuits 102 and 103, and by counting the respective outputs of the detection circuits 102 and 103 using counters 104 and 105, respectively, the first Drive control and the like for the second unfit note stacking units 13 ₁ and 13 ₂ are performed. In this case, the unfit note accumulation section 1
When the operation of 3 ₁ or 13 ₂ is completed, the unfit note counter 106 is incremented by [+100]. Further, the first or second unfit note accumulation section 13 ₁ or 13 ₂ is selected by the accumulation selection circuit 107, and the contents of the counter 104 or 105 are selected and stored in the storage device 108. Therefore, in the event of an abnormal condition such as a jam, a shift error, or a count discrepancy, all valid and unfit notes can be removed from the invalid note stacker without being re-supplied. The predetermined number of supplied paper sheets, for example 100, is confirmed by adding up the number of paper sheets contained in the paper sheet 26 and checking the total number of sheets. The number Q of invalid tickets in the invalid ticket accumulating device 26 in a normal case is Q=H-G ₁ (G ₂ ) However, G ₁ (G ₂ )... is expressed as the contents of the counters 53 ₁ and 53 ₂ , whereas Good banknotes and unfit banknotes accumulating parts 11 ₁ , 11 ₂ , 13 ₁ , when an abnormal condition occurs
The total number of paper sheets taken out from ₁₃₂ and the number of paper sheets in the invalid ticket accumulating device 26 is expressed as follows. [1] When an abnormal condition occurs when only the same bundle is being supplied Q=H-G+RA+RU-PA-PU However, G...G ₁ +G ₂ R4... Contents of storage device 108 RU...

Number of sheets in the th bundle G _o+1 ...Number of sheets in the n+1th bundle supplied after clearing the abnormal condition By performing the above calculation, count verification can be performed. For example, as shown in Figure 4 The number of sheets sorted into the correct bill stacking sections 11 ₁ , 11 ₂ and the unfit bill stacking sections 13 ₁ , 13 ₂ is determined by the circuit shown in FIG. It is stored at predetermined addresses from address 1 to address n along with the received signal. In FIG. 4, 111 is a memory circuit that stores abnormal conditions when they occur, 112 is an arithmetic control circuit, and 113 is an arithmetic circuit, in which the set value H and the counter 53 are stored.
₁ , 53 ₂ , 106, 92 and storage device 108,
Each content of 100 is supplied, the above calculation is performed, and the answer, that is, the calculation result (Q, Q _o ,
Q _o+1 ) is output. Next, the sheet shift circuit used in this apparatus will be explained. This paper sheet shift circuit shifts the determination results output from the detection section 4 according to the conveyance of the corresponding paper sheets, and shifts the judgment results output from the detection section 4 to
and 10, and is configured, for example, as shown in FIG. That is,
121, 122, 123, and 124 are timing signal generation circuits connected to the detectors 29, 30, 31, and 34, respectively;
2, 123, 124 are T ₁ , T ₂ , T ₃ , T ₄ respectively

and a JK type flip-flop circuit (hereinafter simply referred to as FF circuit) 125 ₁ , which constitutes 126 ,
125 ₂ , 125 ₃ , 126 ₁ , 126 ₂ , 126 ₃ ,
126 ₄ and shift check circuits 127 ₁ , 127 ₂ , 127 ₃ and 128 respectively.
₁ , 128 ₂ , 128 ₃ , and 128 ₄ are also supplied as timing signals, respectively. On the other hand, 129 is an invalid ticket determination circuit of the detection section 4, and its output is supplied to the input of the shift register 125, that is, the J and K input terminals of the first stage FF circuit ₁₂₅₁ . Also,
Reference numeral 130 designates an unfit note determination circuit of the detection unit 4, and its output is supplied to the input of the shift register 126, that is, the J and K input terminals of the first stage FF circuit ₁₂₆₁ . Therefore, the invalid ticket determination circuit 129 detects that the FF circuit 1
25 Set ₁ to “1” state. That is, when the leading edge of the paper sheet reaches the detector 29, the timing signal generation circuit 121 outputs the timing signal _T1 , and the signal is transmitted to the shift register ₁ by T1.
The FF circuit 126 ₁ of No. 26 is cleared, and then the data output from the invalid ticket determination circuit 129 is set in the FF circuit 125 ₁ of the shift register 125 in response to the timing signal T ₂ . Then the timing signal
At _T3 , the check circuit ₁₂₇₁ checks whether the above data has been definitely set.
As a result of this check, if the shifted data is different, the shift register 125 is cleared. Note that the timing signal _T4 is a signal for clearing the FF circuit that has been shifted, that is, the FF circuit at the previous stage. Next, when the leading edge of the paper sheet reaches the detector 30, the timing signal generating circuit 1
Timing signals T ₁ to T ₄ are output from 22,
FF circuit 125 ₁ forming shift register 125
The contents of are shifted to the FF circuit ₁₂₅₂ , and the contents of the previous stage are
The contents of FF circuit ₁₂₅₁ are cleared by timing signal _T4 . Further, the FF circuit ₁₂₅₃ is set when the leading edge of a sheet reaches the detector 31, and controls the drive circuit 131 of the sorting device 5 according to the content. That is, when the content of the FF circuit 125 ₃ is "0", the sorting device 5 is controlled so that the paper sheet is conveyed to the invalid ticket stacking device 26 . On the other hand, the unfit bill determination circuit 130 outputs a "1" signal when the paper sheet being conveyed is not an unfit bill. Therefore, when the leading edge of the paper sheet reaches the detector 29, the FF circuit ₁₂₆₁ of the shift register 126 uses the timing signal _T2 output from the timing signal generation circuit 121 to detect "if the bill is unfit." If the note is not an unfit note, it is set to ``1'', and thereafter the contents are sequentially shifted in the shift register 126 in the same way. After that, the detector 34
When the leading edge of the sheet reaches , and data is set in the FF circuit <sub>1264</sub> , the drive circuit 132 of the sorting device 10 is controlled according to the content. That is,
When the content of the FF circuit 126 <sub>4</sub> is "0", the sorting device 10 is controlled so that the paper sheets are conveyed to the unfit bill stacking sections 13 <sub>1</sub> and 13 <sub>2</sub> . Here, the contents written to the shift registers 125 and 126 treat a "0" signal as a meaningful signal. This is done in consideration of safety in transporting paper sheets. In other words, if a "1" signal is being shifted in the shift register and the signal disappears due to the influence of external noise, for example, the paper sheets will be sorted into the stacking section with a higher sorting priority. There must be. For example, if a paper sheet with a damaged note signal loses its signal, the paper sheet will be sorted and stacked in the invalid note stacking device 26. Also, for example, the shift register 12
When the FF circuit <sub>1253</sub> of No. 5 is "0", that is, when the sorting device 5 is in the direction of conveying the paper sheet to the invalid ticket accumulation device 26, for example, when the paper sheet passes the detector 32, the shift mischeck is performed. circuit 13
3 is activated and performs a check. The shift error check circuit 133 is also connected to the detector 35, so that a check is similarly performed when unfit bills are conveyed to the correct bill stacking sections 11 <sub>1</sub> and 11 <sub>2</sub> . In addition, 134 <sub>1</sub> ~ in FIG.
134 <sub>8</sub> are OR circuits. Next, the grip shift circuit used in this device will be explained. When the good bill accumulating units 11 <sub>1</sub> , 11 <sub>2</sub> and the unfit note accumulating units 13 <sub>1</sub> , 13 <sub>2</sub> are driven, this bundle shift circuit holds a signal indicating that the bundle is a good bill or an unfit bill, and sequentially transmits the signal. This is a circuit that shifts and stamps the corresponding bundle bands using the stamping device 24, and then controls the bundle sorting device 25 to sort and accumulate the bundles in the respective bundle stacking sections, for example, as shown in FIG. It is composed of That is, 14
1 is a first genuine bill accumulating unit driving circuit that drives the first genuine bill accumulating unit 11 <sub>1</sub> ; 142 is a second genuine bill accumulating unit driving circuit that drives the second genuine bill accumulating unit 11 <sub>2</sub> ;
The outputs of each of the drive circuits 141 and 142 are sent to a shift register 144 and a shift register 144 via an OR circuit 143.
45 respectively. The shift register 144 includes JK type flip-flop circuits (hereinafter simply referred to as FF circuits) 144 <sub>1</sub> , 144 <sub>2</sub> , 1
44 <sub>3</sub> , 144 <sub>4</sub> , 144 <sub>5</sub> , and the input of this shift register 144, that is, the first stage FF
The output of the OR circuit 143 is supplied to the J input terminal of the circuit <sub>1441</sub> . In addition, the shift register 1
45 is the FF circuit 145 <sub>1</sub> , 145 <sub>2</sub> , 145 <sub>3</sub> , 1

The output of the OR circuit 143 is supplied to the K input terminal of the circuit. On the other hand, 146 is the first unfit bill accumulating section 13 <sub>1</sub>
147 is a second unfit note accumulating unit driving circuit that drives the second unfit note accumulating unit 13 <sub>2</sub> , and each of the drive circuits 146 and 14

are respectively supplied to the J input terminals of the . Further, the detectors 41, 42, 43, 44, 45 are connected to timing signal generation circuits 154, 1 through detection circuits 149, 150, 151, 152, 153, respectively.
55, 156, 157, and 158 are connected to each other, and timing signals generated in each of these circuits 154 to 158 are supplied to the shift registers 144 and 145, respectively. Now, for example, the drive circuit 141 drives the genuine bill accumulating section <sub>111</sub> , and a bundle of 100 genuine bills is carried out to the bundle conveying device 16. When the bundle is conveyed and reaches the detector 41, it is detected. A signal is supplied from the circuit 149 to the timing signal generator circuit 154, whereby a timing signal is output from the timing signal generator circuit 154, and at the timing of the signal, a " <sub>1</sub> " signal is sent to the FF circuit 1441.
A "0" signal is set to <sub>451</sub> . This "1",
The “0” signal is sent to the FF circuits 144 <sub>2</sub> and 14 when the valid bills reach the detectors 42 to 45 in sequence.
5 <sub>2</sub> , 144 <sub>3</sub> and 145 <sup>3</sup> , 144 <sub>4</sub> and 145 <sub>4</sub> , 14
4 <sub>5</sub> and 145 <sub>5</sub> , and finally by the outputs of FF circuits 144 <sub>5</sub> and 145 <sub>5</sub> , a valid bill signal is sent to the stamping control circuit 159 of the stamping device 24 and the folding control circuit of the folding sorting device 25. 160, respectively. As a result, the stamping device 24 stamps the genuine bill, and then the bundle sorting device 25 sorts and stacks the genuine bill in the stacking section.
On the other hand, when the bundle of unfit bills is taken out from the unfit bill stacking section 13 <sub>1</sub> or 13 <sub>2</sub> , a "0" signal is set in the FF circuit 144 <sub>1</sub> and a "1" signal is set in the FF circuit 145 <sub>1</sub> .
The subsequent shift operation is performed in the same manner as in the case of the regular bill stack. Also, if the bundle is transported, "1" is applied to both the FF circuits 144 <sub>1</sub> and 145 <sub>1</sub> .
Alternatively, when the "0" signal is set, the shift check circuits 161, 162, 163, 16
4,165 operate, each FF circuit 144 <sub>1</sub>
Clear 144 <sub>5</sub> and 145 <sub>1</sub> to 145 <sub>5</sub> , respectively. Therefore, since the bundle at this time does not have a signal, the unfit note indication is finally stamped and the bundle is sorted and accumulated in the unfit bill stacking section. In this way, if the bundle shift signal disappears due to noise or the like, that bundle is treated as a damaged banknote. Furthermore, the time during which the bundles are conveyed between the detectors 41 to 45 is approximately constant, so if a problem such as physical failure of conveyance occurs, the time required for conveying the bundles between the detectors 41 to 45 is approximately constant. It is detected by jam check circuits 166, 167, 168, and 169 provided. This checking method includes, for example, measuring the transportation time of the bundle between each of the detectors 41 to 45,
If the time is shorter or longer than a predetermined fixed time, it is detected as a jammed state. Note that it is possible to input bundles from the collection device 19 solely for the purpose of bundling, but in that case, for the reason mentioned above, the bundles do not have a signal, so they are treated as unfit bills, and the unfit note indication is stamped. The unfit notes are sorted and accumulated in the unfit note stacking section. Further, the timing signal output from the timing signal generation circuit 154 is supplied to a direction change control circuit 170, and the direction change device 17 is controlled by this control circuit 170. Further, the timing signal output from the timing signal generation circuit 156 is supplied to the procurement control circuit 171,
The procurement device 19 is controlled by this control circuit 171. Furthermore, the timing signal output from the timing signal generation circuit 157 is supplied to a sealing control circuit 172, and the sealing device 21 is controlled by this control circuit 172. Note that 173 <sub>1</sub> to 173 <sub>9</sub> in FIG. 6 are OR circuits, respectively. Next, the jam detection circuit used in this device will be explained. This jam detection circuit detects one of the sheets of paper.
If any problem occurs during sheet transport,
In order to prevent damage to the device, this circuit immediately detects such a state, and is configured as shown in FIG. 7, for example. That is, the detectors 31, 32, 33 include detection circuits 181, 182,
183 are connected to each other. The output of the detection circuit 181 is supplied to a jam check circuit 184, and each output of the detection circuits 182 and 183 is supplied to the jam check circuit 184 via an OR circuit 185. The jam check circuit 184 is also supplied with the output of a time setting circuit 186. Therefore, in the part of the sorting device 5, after the sheet passes through the detector 31, the sheet is sent to the detector 32.
Alternatively, the jam check circuit 184 checks the time when the paper sheet reaches 33, and if that time is longer than the fixed time set in the time setting circuit 186, it is determined that the sheet has jammed in the sorting device 5. A signal is output from the jam check circuit 184, and the jam indicator 187 displays it. Further, a detection circuit 188 is connected to the detector 34, and the output of this detection circuit 188 is supplied to jam check circuits 189 <sub>1</sub> , 189 <sub>2</sub> , 189 <sub>3</sub> , respectively.
<sub>1</sub> , 189 <sub>2</sub> , 189 <sub>3</sub> have time setting circuits 190 <sub>1</sub> ,
Outputs 190 <sub>2</sub> and 190 <sub>3</sub> are also supplied respectively. And the jam check circuit 189 <sub>1</sub> ,
The outputs of 189 <sub>2</sub> and 189 <sub>3</sub> are respectively supplied to a jam indicator 192 via an OR circuit 191. In the sorting device 10, the jam check circuit <sub>1891</sub> checks the time taken for the paper sheet to pass through the detector 34, and if the time is longer than the fixed time set in the time setting circuit <sub>1901</sub> , The jam check circuit 189 <sub>1</sub> determines that the sheet has jammed in the sorting device 10 or that two or more sheets have been conveyed in succession.
A signal is output from. In addition, the paper leaf is detected by the detector 34.
The jam check circuit <sub>1892</sub> checks the time it takes to pass the
If the time is shorter than the fixed time set in <sub>step 2</sub> , it is determined that a skew of paper sheets has occurred or that something other than paper sheets has been conveyed, and a signal is output from the jam check circuit <sub>1892</sub> . Further, the jam check circuit 189 <sub>3</sub> checks the time interval between the sheet passing through the detector 34 and the next sheet, and if the time interval is shorter than the fixed time set by the time setting circuit 190 <sub>3</sub> . , it is determined that the interval between the sheets is too short, and a signal is output from the jam check circuit <sub>1893</sub> . In this way, when a signal is output from the jam check circuits 189 <sub>1</sub> , 189 <sub>2</sub> , 189 <sub>3</sub> , the jam indicator 192 is activated to display it. Further, the other detectors 35 to 40 are also connected to the same circuits as the detector 34, and the same three types of checks as described above are performed, and if a jam or the like occurs, it is checked. is now displayed. Next, the overall operation of the apparatus configured as described above will be sequentially explained with reference to the flowchart shown in FIG. Note that each flow in this flowchart is divided as shown in the lower left of the figure. Furthermore, the 1,000 sheets of paper to be sorted in this explanation are tied together with a frenulum every 100 sheets, and this is called a "bundle." Every 10 bundles are tied together with a large obi, and this is called a ``bundle.'' (1) Take out the bundle and number the obi. (2) Remove the obi and store the obi. (3) One of the ten bundles is taken out, the frenulum is numbered, and then the frenulum is removed, the frenulum is placed in the band accumulating box 46, and the paper sheets are placed on the supply section 1. (4) After numbering the frenulums of all the bundles (in this example, 10 bundles, that is, one bundle worth of bundles), remove the frenulums, and place the frenulums in order into the belt collection box 46. , and the paper sheets are stored in order in the supply section 1. (5) The supply unit 1 pushes out the first bundle of sheets to the take-out device 2 side. (6) The paper sheets are sequentially taken out one by one from the supply section 1 by the take-out device 2. (7) When the removed paper passes through the detection unit 4, the state of the paper is detected, and it is determined whether the paper is a stacked ticket, a counterfeit ticket, a different type of ticket, an expired ticket, a valid ticket, a damaged ticket, etc. be exposed. (8) When determining the detection results for paper sheets, one determination result signal is given to the paper sheets in accordance with the priority order. (9) This determination result signal is shifted by a sheet shift circuit, and in front of the sorting devices 5 and 10, the sorting direction of the sorting device is determined according to the signal, and the sheet is guided in that direction. (10) The sorting device 5 guides invalid bills (paper sheets other than regular bills and unfit bills) to the invalid bill accumulating device 26. (11) The normal notes and unfit notes reach the sorting device 10, where they are sorted into normal notes and unfit notes in accordance with the shift signal in the same manner as described above. (12) Paper sheets passing through the sorting device 10 are counted by counters 53 ₁ and 53 ₂ . (13) The paper sheets sorted into regular bills by the sorting device 10 are counted by a counter 81 in front of the sorting device 12, and every 100 sheets are counted in the sorting direction of the sorting device 12, that is, the regular bill accumulating section 11 ₁ , 11 ₂ is switched. (14) At the entrance of the genuine bill accumulation sections 11 ₁ and 11 ₂ ,
The number of paper sheets guided there is the counter 85,8
Counted by 6. (15) The paper sheets sorted into unfit notes by the sorting device 10 are postmarked by the postmark device 15 and sent to the sorting device 10.
4, and the sorting direction of the sorting device 14, that is, the unfit bill accumulating sections 13 ₁ and 13 ₂ are switched every 100 sheets. (16) When the supply of one batch is completed and it is confirmed that there is no shift error or counting error, the contents of the counters 53 ₁ and 53 ₂ are stored in the storage device 71 via the arithmetic circuit 70 along with the batch number. . (17) When the stacking section to which the paper sheets are guided is switched when the number of good or unfit bills is 100, the stacking section where the 100 sheets have been stacked is driven, and the bundle of 100 sheets is transferred to the bundle conveying device 16. It is carried out and conveyed to the direction changing device 17. (18) The grip that has reached the direction change device 17 is now approximately
The direction is changed by 90 degrees and conveyed to the collection device 19. (19) The bundles that have arrived at the collection device 19 are arranged into a rectangular shape, including bundles that are poorly stacked, and are conveyed to the sealing device 21. (20) The bundles that have reached the sealing device 21 are sealed here, and the next stamping device 24 stamps and displays the necessary information, and the surface of the wrapping paper is changed according to the shift signal from the bundle shift circuit. The classification of good or unfit notes is displayed. (21) The bundles stamped and displayed by the stamping device 24 are sorted into good bill bundles or damaged bill bundles by the bundle sorting device 25, and guided to the corresponding bundle stacking section. (22) On the other hand, paper sheets that have been determined by the detection unit 4 to be stacked tickets, counterfeit bills, different types of bills, and expired tickets and which have been led to the invalid ticket stacking device 26 by the sorting device 5 are collected by the operator. The sheets are taken out from the stacking device 26 and the number of sheets is counted. Also, counterfeit tickets,
The operator confirms the different types of tickets and expired tickets again. (23) The operator uses the numeric keypad 75 to input the total number of bills accumulated in the invalid bill accumulation device 26 and the number of counterfeit bills, foreign bills, and expired bills. (24) When the number of bills is input using the numeric keypad 75, the difference between the number of good and unfit bills counted by the counters 53 ₁ and 53 ₂ and the set value H is retrieved from the storage device 71, and the difference is inputted with the above input. The comparator 76 compares the number of printed sheets to check whether there is an excess or shortage. (25) As a result of the above verification, there is no excess or deficiency in the 100 sheets, and the number of counterfeit, foreign, and expired notes has been determined.

If you enter [0], invalid ticket integrated circuit 26
The next batch of stacked tickets, counterfeit bills, dissimilar bills, and expired tickets are taken out from there and the above operation is repeated. (26) As a result of the above verification, if there is an excess or deficiency of 100 sheets, the input value is displayed on the display 80, so the operator visually confirms the input error. At this time, if an input error is made, input the correct number using the numeric keypad 75 again. If this re-input does not result in an excess or shortage of 100 sheets, the printer 48 prints the bundle number, the number of input errors, and the number of re-inputs, and the key input device 47, which was locked due to the input error, is printed.
The lock is automatically released and the next batch is processed. (27) If excess or deficiency occurs and there is no input error, or if excess or deficiency occurs even after re-input, the key input device 47 is locked. This locked state can only be released using a key owned by the supervisor. When the key input device 47 is locked, the supervisor takes out the frenulum of the corresponding bundle in which excess or deficiency has occurred from the band accumulation box 46 according to the number displayed on the display 77 at this time, and then cancels the lock. At this time, the bundle number and the total number of bundles printed by the printer 48 are received. (28) Enter the number of counterfeit tickets, foreign tickets, and expired tickets using the numeric keypad 75.

If a value other than [0] is entered, the key input device 47 is
is locked. In this case, the operator hands over the counterfeit note, foreign note, expired note, and the frenulum from which they appeared to the supervisor to have the locked state released. When this lock is released, the printer 48 prints the number of counterfeit bills, foreign bills, and expired bills that have been input, and the number of their bundles. (29) The number of bills entered using the numeric keypad 75 is stored in the storage device 71, and before the number of bills for the next batch is input, the total number of bills accumulated in the invalid ticket stacking device 26 up to the previous batch and the counterfeit bills, These are added to the total number of different types of tickets and expired tickets and stored. (30) If a jam occurs in the sorting device or the stacking section, or if a shift error occurs in the sorting device 5, the jam detection circuit detects this and stops the conveyance of paper sheets. In this case, the location where the occurrence occurs is displayed, the paper sheets at that location are corrected or taken out, and then all the paper sheets on the conveyance path are accumulated. At this time, the extraction device 2 is in a stopped state. (31) In addition, 100-sheet sorting mistakes (when there is doubt about the number of stacked 100 sheets), verification mistakes (when irrationality occurs in counting verification), or shift mistakes (when unfit bills are classified as good bills) The removal of paper sheets is stopped, and the paper sheets on the conveyance path are accumulated in the stacking section. (32) After (30) and (31) above, all the paper sheets are taken out from each stacking section and stored in the take-out ticket box 27. (33) After the process in (32) above is completed, the supply is started again, and after the classification of one batch is completed, the number of sheets after the process in (32) above is completed is counted by the counter 53 ₁ , 5
3 ₂ and performs the above-mentioned calculation, and the result is stored in the storage device 71 along with the abnormality code. (34) In order to count and verify the paper sheets in the invalid ticket accumulating device 26 for the bundle in (33) above, jam,
100 As in the case where there is no sorting error, collation error, or shift error, by taking out the paper sheets from the invalid ticket accumulation device 26 and inputting the total number of sheets and the number of counterfeit tickets, different types of tickets, and expired tickets using the numeric keypad 75. , the key input device 47 is locked due to excess or deficiency. By counting the number of paper sheets in the take-out ticket box 27 using an ordinary counter and inputting the number using the numeric keypad 75, the key input device 47 is unlocked if there is no excess or deficiency. At this time, the printer 48 prints the number of sheets in the takeout ticket box 27. (35) If an excess or deficiency occurs in (34) above, the same process as in (27) above is performed. (36) Out of the bundles, large obi, and small obi that have been verified, those that contain too many or too many counterfeit, mismatched, or expired notes will be discarded. (37) After the sorting operation and verification using the key input device 47 are completed, the printer 48 prints the sum of the total number of invalid ticket accumulators 26 and the number of counterfeit bills, different types of bills, and expired tickets. , the operator can reconfirm the number of those sheets on hand. As explained above, according to the above embodiment, 100
It is possible to reliably determine whether there is an excess or deficiency in the number of sheets, as well as whether there are good, unfit, or invalid notes on a sheet-by-sheet basis.Therefore, it is possible to determine in which bundle of 100 sheets in a bundle of 1000 sheets an abnormality occurred. can be determined. This results in
It is possible to easily know which handler has handled the handle that has an abnormality. In addition, there is no need to insert a classification card every 100 tickets as in the past, and the number of tickets can be confirmed without resupplying stacked tickets, so even if processing is done in units of 100 tickets, However, there is little reduction in processing capacity, and the burden on the operator can be reduced. In the above embodiment, a case has been described in which paper sheets such as securities are sorted, but the present invention is not limited to this, and the present invention can be implemented in the same way when sorting other paper sheets such as slips. In addition, the present invention is not limited to the above-mentioned embodiments, and it goes without saying that various modifications can be made without departing from the gist of the present invention. As described in detail above, according to the present invention, a predetermined number of paper sheets to be sorted are set in the supply unit, the set paper sheets are taken out one by one by the take-out device, and the taken-out paper sheets are A sorting detection section detects the sorting of the leaves into valid sheets, invalid sheets, stacked sheets, etc., and the sorting device sorts the sheets that have passed through the sorting detection section into the valid sheets. The paper sheets are sequentially guided to the first conveyance path and counted and recorded every predetermined number of sheets, and the invalid sheets and stacked sheets are guided to the second conveyance path and counted every predetermined number of sheets. The predetermined number of sheets is checked by checking the accumulated invalid paper sheets and stacked sheets, counting the number of sheets, and comparing the number with the recorded contents. It minimizes the downtime of the device itself to minimize deterioration in processing capacity and increase in the burden on the operator. It also reduces wasted time between each unit when processing paper sheets in units of 100 sheets, and also reduces the time required to insert sorting cards. It is possible to provide a paper sheet sorting device that can efficiently process paper sheets by eliminating the burden on the operator.
