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. Conventionally, paper sheet sorting devices have been used that automatically inspect paper sheets such as securities and classify them into valid and invalid ones.
- There is a device as shown in Publication No. 61162. In this device, a sorting card is inserted into the supply section for each predetermined number of paper sheets (usually 100 sheets sealed in a band), and the paper sheets are taken out one by one and inspected to determine whether they are valid or not. The paper sheets are classified into paper sheets, invalid sheets, and undeterminable rejected sheets, and the number of valid sheets is counted. Furthermore, when the sorting card is taken out, it is determined whether the count value has reached a predetermined value, and if it does not match the predetermined value, the number of excess or deficiency is printed on the sorting card. In addition, if there are any rejected paper sheets, the sorting card is inserted into a counting device installed separately from the paper sheet sorting device to read the number of surplus or insufficient sheets, and the rejected paper sheets are inserted one by one. and count. Then, by determining whether or not the number of rejected sheets matches the number of missing sheets, it is confirmed whether or not the number of sheets set in the supply section is a predetermined number (100 sheets). However, with this device, it is first necessary to insert a predetermined number of classification cards.
Requires effort from the operator. In addition, since the rejected paper sheets are input and counted one by one into a counting device installed separately from the paper sorting device, the operator must face a counting device separate from the paper sorting device. Otherwise, the operating rate of the paper sheet sorting device will decrease. Furthermore, since the paper sheets are inputted one by one, it becomes a very troublesome work and has the problem of increasing the processing time. The present invention has been made in order to solve the above-mentioned problems, and it is an object to provide a paper sheet sorting device with high processing efficiency, which reduces the burden on the operator and reduces the downtime of the device. However, since the above-mentioned conventional sorting device performs so-called batch processing in which 1000 sheets are counted as a unit, it is possible to determine whether there is an excess or deficiency in the number of sheets or whether there are counterfeit notes in units of 1000 sheets. , 1000
It is not possible to determine whether or not an abnormality occurred in a group of 100 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. Furthermore, although all 1,000 sheets of paper are typically handled at the same processing location, each bundle 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 this is processed in units of 100 sheets using the same method as before,
Since the number of bills is checked and counterfeit bills are processed every 100 bills, the device itself spends a lot of time inactive, which significantly reduces the device's processing capacity and reduces 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-mentioned circumstances, and its purpose is to reduce the inoperable time of the device itself, thereby minimizing a decrease in processing capacity and an increase in the burden on the operator, and, for example, in units of 100 sheets. It is an object of the present invention to provide a paper sheet sorting device that can process paper sheets efficiently with less wasted time between each unit and eliminates the burden on the operator for inserting a sorting card. 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 (hereinafter simply referred to as paper sheets) such as securities are set in a three-dimensional state in units of, for example, 100 sheets. is supplied 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 stacking 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 to detect the abnormal approach of the paper sheets taken out by the take-out device 2, since it becomes impossible to accurately detect and count the sheets as described above. This detection means detects, for example, the spacing between sheets and compares the spacing with the normal spacing. The fourth function is to examine the contents of each paper sheet that is being conveyed to identify invalid notes (counterfeit notes, foreign notes, expired notes, and other suspicious paper sheets) and damaged notes (paper sheets unsuitable for reuse). ). This detection means may use any other well-known optical method or mechanical method as long as it is effective for achieving the intended purpose. Furthermore, 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 (reusable paper sheets). 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.

The printer 48 prints on the receipt the numerical value entered using the numeric keypad 74, the number of excess or deficiency in the predetermined number of tickets, and the number of invalid tickets if there are any. . 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 ,
This is a circuit that compares the sum of the number of valid and unfit bills and the number of invalid and stacked bills inputted from the key input device 47 with a set value H which is a specific number (for example, 100), for example, as shown in FIG. It is configured as shown in . That is, assuming that the number of paper sheets to be supplied now is the same as the set value H, the invalid bill stacking device 26, the valid bill stacking units 11 ₁ , 11 ₂ , and the unfit bill stacking unit 1
The sum of the number of sheets separately accumulated in 3 ₁ and 13 ₂ is H sheets. Therefore, the output of the detection circuit 51 connected to the detector 34 is output from the AND circuit 52.
to the total number counter 53 via the detector 35.
The output of the detection circuit 54 connected to the detector 36 is sent to the total number counter 56 via an AND circuit 55, and the output of the detection circuit 57 connected to the detector 36 is sent to the total number counter 59 via an AND circuit 58. Each is supplied. On the other hand, a detection circuit 6 connected to the detector 28
The output of 0 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
AND circuits 52, 55,
58 gates are controlled. Then, after a certain period of time has elapsed since the detector 28 detects that the predetermined number (H) of sheets have all been taken out, the contents of the counters 56 and 59 are transferred to the adder via AND circuits 65 and 66. 67 for addition, and the addition result is supplied to comparator 68. Further, the contents of the counter 53 are supplied to the comparator 68 via an AND circuit 69, and the contents of the counter 53 are supplied to the adder 68.
It is compared with the output of 7. As a result of this comparison, if the two do not match, the device is in an abnormal state.
Therefore, in this case, the mismatch display 70 displays a mismatch. Note that the AND circuits 65, 6
6 and 69 are controlled by a verification control circuit 71 that operates in accordance with the output of the timing signal generation circuit 61. On the other hand, if the two match as a result of the above verification, the arithmetic circuit 72 calculates the difference between the contents of the counter 53 and the set value H, and the result is sent to the comparator 73.
supply to. The comparator 73 is also supplied with the number of invalid tickets and stacked tickets input using the numeric keypad 74 via the input control circuit 75, and is compared with the output of the arithmetic circuit 72. As a result of this verification, if there is no excess or deficiency in the number of sheets, the take-out device 2 starts taking out the next predetermined number of sheets. On the other hand, if there is an excess or deficiency in the number of sheets as a result of the verification, this is displayed on a display (not shown) and the apparatus is locked so that it cannot be operated again. At this time, the numerical value (number of tickets) entered using the numeric keypad 74 is displayed on the display 76, so that the operator can visually check the entered numerical value and the number of invalid tickets and stacked tickets, and input the number. If you made a mistake, enter the correct number again. This re-input number of sheets is supplied to the comparator 73 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 prints out the previous numerical value entered using the numeric keypad 74, the excess/deficiency number, and the re-entered numerical value, respectively.
Eject the printed receipt. In addition, if there is no mistake in the number of sheets entered previously, or if there is a difference in the number of sheets entered even after re-entering, the supervisor can unlock the device which is in the locked state, and the number of sheets can be changed to the previous number. The take-out device 2 starts taking out the next predetermined number of sheets in the same way as when there is no excess or shortage. At this time, the printer 48 operates, prints out the numerical value inputted using the numeric keypad 74 and the number of surplus or insufficient sheets, and discharges the printed receipt. Furthermore, if there are invalid tickets at this time, the number of invalid tickets is also printed. On the other hand, the numerical value input using the numeric keypad 74 is also supplied to the addition storage device 77, where it is added to the numerical value input using the previous key and stored. Then, after the sorting process for the same bundle of paper sheets is completed for a certain period of time, for example, every hour, when the paper sheets accumulated in the invalid ticket accumulation device 26 are processed by pressing a reprocessing button (not shown), the above-mentioned addition storage device The contents of 77 are supplied to the comparator 73 and compared with the contents counted by the counter 53 to check again for key input errors. Next, a method for checking the number of sheets sorted and stacked in each stacking section will be explained. When the contents of the valid bill sorting counter 81, which is counted by obtaining a signal from the detector 35, match the set value D (100 in this example), a matching signal is output from the comparator 82, which causes the sorting control circuit 83 and the drive The sorting device 12 is driven by the circuit 84, and the sheets being conveyed 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 unit 11 ₁ and then stacked in the second genuine bill stacking unit 11 ₂ , then one of the counters 85 and 86 will be stacked. The contents of the counter 85 selected by the control circuit 83 via the gate circuit 87 and the set value D are transferred to the comparator 8.
8 to be compared. As a result of this comparison, if the two match, the first genuine bill accumulating unit 11 ₁ is immediately driven by the integrated control circuit 89 and the drive circuit 90 ₁ , and
A bundle of 100 paper leaves is carried out. Here, the operations of the comparator 88 and the control circuit 89 are as follows:
This is performed in response to a predetermined timing signal output from a timing signal generation circuit 91 which operates in accordance with the output of No. 2. 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 perform counting operations by being supplied with respective outputs of detection circuits 94 and 95 connected to the detectors 37 and 38, respectively. Further, the control circuit 83 is adapted to control an integrated selection circuit 96, and the selection circuit 96 selects the drive circuits 90 ₁ and 90 ₂ . Further, the selection circuit 96 is connected to the counter 8 via a gate circuit 97.
5, 86 and supplies the contents of the selected counter to the comparator 98. This comparator 98 compares the content of the counter 81 with the content of the counter 85 or 86, and operates a mismatch indicator 99 if the two do not match. Then, the counter 85 or 86 selected by the selection circuit 96
The contents of 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 collecting unit 13 are sorted by the sorting device 14 in the same manner as in the case of normal notes. Switching control for ₂ is performed. Similarly, the detectors 39, 4
Detection circuits 102 and 103 are connected to the 0, respectively, and by counting the respective outputs of the detection circuits 102 and 103 by 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 accumulating section 13
When the operation ₁ or ₁₃₂ 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 in the invalid bill accumulating device 26 in the normal case is Q=H-G However, G... is expressed as the contents of the counter 53, whereas the number Q in the invalid bill accumulating unit 26 in the case of an abnormal condition is expressed as the contents of the counter 53. The total number of paper sheets taken out from 11 ₁ , 12 ₂ , 13 ₁ , 13 ₂ and the number of paper sheets in the invalid ticket stacking device 26 is expressed as follows. Q=HG+RA+RU-PA-PU However, RA...Contents of storage device 108 RU...Contents of storage device 100 PA...Contents of counter 106 PU...Contents of counter 92 Each operation described above is, for example, This can be easily done using the circuit shown in FIG. In addition, the third
In the figure, 111 is an abnormal state storage circuit that stores abnormal states when they occur, 112 is an arithmetic control circuit, and 113 is an arithmetic circuit, which includes the set value H, counters 53, 106, 92, and a storage device 108. , 100 are respectively supplied, and the above calculation is performed to obtain the answer, that is, the calculation result (Q).
Output. Next, the sheet shift circuit used in this apparatus will be explained. This sheet shift circuit is a circuit that shifts the determination result output from the detection section 4 according to the conveyance of the corresponding sheet, and controls the sorting devices 5 and 10, respectively. For example, as shown in FIG. Constructed as shown. That is, 12
1, 122, 123, and 124 are timing signal generation circuits connected to the detectors 29, 30, 31, and 34, respectively;
123 and 124 generate timing signals T ₁ , T ₂ , T ₃ and T ₄ , respectively. The generated timing signals T ₁ to _{T 4} are transmitted to J-K flip-flop circuits (hereinafter simply referred to as FF circuits) 125 ₁ , 12 which constitute shift registers 125 and 126 .
5 ₂ , 125 ₃ , 126 ₁ , 126 ₂ , 126 ₃ , 12
6 ₄ respectively, and shift check circuits 127 ₁ , 127 ₂ , 127 ₃ and 128 ₁ , 1
28 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 . Further, 130 is an unfit note determination circuit of the detection unit 4, and its output is sent to the shift register 126.
In other words, it is supplied to 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 shift register ₁₂ is triggered by the signal _T1 .
The FF circuit 126 ₁ of the shift register 125 is cleared, and then the data output from the invalid ticket determination circuit 129 with the timing signal T ₂ is sent to the FF circuit 12 of the shift register 125.
5 Set to ₁ . Then the timing signal T ₃
Then, the check circuit ₁₂₇₁ checks whether the above data has been set reliably. 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 in the previous stage. Next, when the leading edge of the paper sheet reaches the detector 30, the timing signal generation circuit 12
Timing signals T ₁ to _{T 4} are output from FF circuit 125 2, and the contents of FF circuit 125 ₁ constituting the shift register 125 are shifted to FF circuit 125 2, and the contents of the FF circuit 125 ₂ of the previous stage are shifted.
The contents of 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, the above FF circuit 1
When the content of 25 ₃ is "0", the sorting device 5 is controlled so that the paper sheet is conveyed to the invalid ticket accumulating 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 receives the timing signal _T2 output from the timing signal generating circuit 121, and the FF circuit 1261 of the shift register 126 outputs "0" if the note is unfit. ", and if the note is not unfit, 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 ₁₂₆₄ , 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 ₄ is "0", the sorting device 10 is controlled so that the paper sheets are conveyed to the unfit bill stacking sections 13 ₁ and 13 ₂ . Here, the contents written to the shift registers 125 and 126 treat the "0" signal as a meaningful signal. This is done in consideration of safety when 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, the paper sheet will be sorted into a stacking section with a higher sorting priority. There must be. For example, if a paper sheet with a damaged note signal loses that 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 ₁₂₅₃ of No. 5 is “0”, that is,
For example, when a sheet passes through the detector 32 while the sorting device 5 is in the direction of conveying the sheet to the invalid ticket accumulating device 26, the shift mischeck circuit 1
33 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 ₁ and 11 ₂ . In addition, 134 ₁ in Figure 5
_-1348 are OR circuits, respectively. Next, the grip shift circuit used in this device will be explained. When the good bill accumulating units 11 ₁ , 11 ₂ and the unfit note accumulating units 13 ₁ , 13 ₂ 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 the stamp, stamps the corresponding bundle band with the stamping device 24, and then controls the bundle sorting device 25 to sort and accumulate the bundles in each bundle stacking section, for example, as shown in FIG. It is composed of That is, 14

The output of the OR circuit 143 is supplied to the K input terminal of the circuit. On the other hand, 146 is a first unfit note accumulating unit driving circuit that drives the first unfit note accumulating unit 13 ₁ , 147 is a second unfit note accumulating unit driving circuit that drives the second unfit note accumulating unit 13 ₂ , The outputs of these drive circuits 146 and 147 are connected to the FF circuit 1 through an OR circuit 148.

49, 150, 151, 152, and 153, respectively, to the timing signal generation circuits 154 and 15.
5, 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 stacking unit ₁₁₁ , 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 generation circuit 154, whereby a timing signal is output from the timing signal generation circuit 154, and at the timing of the signal, a " ₁ " signal is sent to the FF circuit 1441.
A “0” signal is set to ₅₁ . This "1",
The “0” signal is sent to the FF circuits 144 ₂ and 14 when the valid bills reach the detectors 42 to 45 in sequence.
5 ₂ , 144 ₃ and 145 ₃ , 144 ₄ and 145 ₄ , 14
4 ₅ and 145 ₅ , and finally by the outputs of FF circuits 144 ₅ and 145 ₅ , 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 ₁ or 13 ₂ , a "0" signal is set in the FF circuit 144 ₁ and a "1" signal is set in the FF circuit 145 ₁ .
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 ₁ and 145 ₁ .
Alternatively, when the "0" signal is set, the shift check circuits 161, 162, 163, 16
4,165 operate, each FF circuit 144 ₁
Clear 144 ₅ and 145 ₁ to 145 ₅ , 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, when the bundle shift signal disappears due to noise or the like, the bundle is treated as a damaged bundle. 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, for example, measures 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. Further, the timing signal outputted from the timing signal generation circuit 157 is transmitted to the sealing control circuit 1.
72, and the sealing device 21 is controlled by this control circuit 172. Note that 173 ₁ to 173 ₉ in FIG. 6 are OR circuits, respectively. Next, a 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. 6, 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 or 3.
3 is reached in the jam check circuit 184, and if that time is reached, the time setting circuit 186
If the time is longer than the predetermined time, it is determined that the sheet is jammed in the sorting device 5, and a signal is output from the jam check circuit 184, which is displayed on the jam indicator 187. 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 ₁ , 189 ₂ , 189 ₃ , respectively.
₁ , 189 ₂ , 189 ₃ have time setting circuits 190 ₁ ,
Outputs 190 ₂ and 190 ₃ are also supplied respectively. And the jam check circuit 189 ₁ ,
The outputs of 189 ₂ and 189 ₃ are respectively supplied to a jam indicator 192 via an OR circuit 191. In the sorting device 10, the jam check circuit ₁₈₉₁ 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 ₁₉₀₁ , The jam check circuit ₁₈₉₁ outputs a signal when it is determined that the sheet is jammed in the sorting device 10 or that two or more sheets are being conveyed in succession. Also, the jam check circuit 189 ₂ checks the time it takes for the sheet to pass through the detector 34 , and if the time is determined by the time setting circuit 190 ₂ .
If the time is shorter than the fixed time set in , it is determined that a skew of paper sheets has occurred or that something other than paper sheets has been conveyed, and the jam check circuit 1 is activated.
A signal is output from 89 ₂ . Further, the jam check circuit ₁₈₉₃ checks the time interval between the sheet passing through the detector 34 and the next sheet, and if the time interval is
If it is shorter than the fixed time set in ₀₃ ,
It is determined that the interval between the sheets is too short, and a signal is output from the jam check circuit ₁₈₉₃ . In this way, the jam check circuits 189 ₁ , 189
When a signal is output _{from 2,1893} , 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. In addition, the 1000 sheets of paper to be sorted in this explanation are bundled 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, remove the obi, and store the obi. (2) Remove one bundle of frenulum from the ten bundles, place the frenulum in the band collection box 46, and place the paper sheets on the supply section 1. (3) Remove the frenulum from all bundles (10 in this example) and store the frenulum in the band collection box 46 and the paper sheets in the supply section 1. (4) The supply unit 1 pushes out the first bundle of sheets to the take-out device 2 side. (5) The paper sheets are sequentially taken out one by one from the supply section 1 by the take-out device 2. (6) When the taken out 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. (7) When determining the detection results for paper sheets, one determination result signal is given to the paper sheets in accordance with the priority order. (8) 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. (9) The sorting device 5 guides invalid bills (paper sheets other than regular bills and unfit bills) to the invalid bill accumulating device 26. (10) The normal notes and unfit notes reach the sorting device 10, and are sorted into normal notes and unfit notes in accordance with the shift signal in the same manner as described above. (11) The paper sheets passing through the sorting device 10 are counted by the counter 53. (12) 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. (13) 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. (14) The paper sheets that have been 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. (15) When the stacking section to which the paper sheets are guided changes when the number of good or unfit bills is 100, the stacking section that has accumulated 100 sheets is driven, and the bundle of 100 sheets is placed on the bundle conveying device 16. It is carried out and conveyed to the direction changing device 17. (16) The handle 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. (17) 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. (18) The bundle that has reached the sealing device 21 is 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. (19) 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. (20) On the other hand, paper sheets that are determined by the detection unit 4 to be stacked tickets, counterfeit bills, different types of bills, and expired tickets and guided to the invalid ticket stacking device 26 by the sorting device 5 are collected by the operator. The sheets are taken out from the device 26 and the number is counted. Also, counterfeit tickets,
The operator confirms the different types of tickets and expired tickets again. (21) The operator uses the numeric keypad 74 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. (22) When the number of sheets is input using the numeric keypad 74, the comparator 73 compares it with the output of the arithmetic circuit 72 (the difference between the contents of the counter 53 and the set value H) to determine whether there is an excess or shortage. Verify.
As a result of this verification, there is no excess or deficiency of 100 counterfeit tickets.
Number of different types of tickets and expired tickets

If [0] is input, the next bundle of sheets is sent to the take-out device 2 by the supply section 1, and the sheets are taken out one by one by the take-out device 2 again. (23) As a result of the above verification, if there is an excess or deficiency in the 100 sheets, the input value is displayed on the display 76, so the operator visually checks it to confirm input errors. At this time, if you make an input error, press the numeric keypad 74 again.
Enter the correct number. By this re-input
If there is no surplus or shortage of 100 sheets, the printer 48
The number of input errors and the number of re-inputs are printed, and the device that was locked due to input errors is automatically unlocked and the next batch is processed. (24) If an excess or deficiency occurs and there is no input error, or if an excess or deficiency occurs even after re-entering, this device will be locked. This locked state can only be released using a key owned by the supervisor. When the device is locked, the supervisor receives the frenulum of the corresponding bundle where excess or deficiency occurred and the number of excess or deficiency of bundles printed by the printer 48 when the device is unlocked. (25) Use the numeric keypad 74 to enter the number of counterfeit tickets, foreign tickets, and expired tickets.

If a value other than [0] is entered, the device will be locked in the same way as when there is an excess or deficiency in the number of sheets. 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 condition released. When this lock is released, the number of counterfeit bills, foreign bills, and expired bills that have been input are printed by the printer 48. (26) 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. (27) In addition, 100-sheet sorting errors (when there is doubt about the number of stacked 100 sheets), verification mistakes (when an unreasonableness 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. (28) After (26) and (27) above, all the paper sheets are taken out from each stacking section and stored in the take-out ticket box 27. (29) After the process in (28) above is completed, the supply is restarted, and after the sorting of one batch is completed, invalid tickets are processed as if there were no jams, 100-sheet sorting error, collation error, or shift error. Accumulator 26
The total number of paper sheets and the number of counterfeit notes, foreign notes, and expired notes are entered using the numeric keypad 74. In this case, since the number of sheets supplied after the above process (28) is completed and the number of sheets entered using the numeric keypad 74 are totaled, the number of sheets is insufficient and the apparatus is locked. Then, by counting the number of paper sheets in the take-out ticket box 27 using a normal sheet counting machine and inputting the number using the numeric keypad 74, if there is no excess or shortage, the device is unlocked. At this time, the printer 48 prints the number of sheets in the takeout ticket box 27. (30) Out of the large obi and small obi of bundles and bundles for which verification has been completed, any excess or deficiency in the number of obi, counterfeit notes, different types of notes, or expired notes will be discarded. (31) After a certain period of time, for example, every hour, after the processing of sorting the bundles of the same bundle is completed, the invalid ticket accumulating device 26
By pressing the reprocessing button, the paper sheets and jams accumulated in the machine, the paper sheets taken out due to collation errors, shift errors, etc., are reprocessed. At this time, all paper sheets are classified as unfit notes. The number of paper sheets etc. accumulated in the invalid ticket accumulation device 26 is input using the numeric keypad 74 and is stored in the addition storage device 77, so the content is compared with the content of the counter 53 at this time. 7
By comparing and collating in step 3, check again for key input errors. As explained above, according to the above embodiment,
It is possible to reliably determine whether the number of tickets is too large or too short in units of 100, and whether there are valid, damaged, or invalid bills.
Therefore, it is possible to determine which bundle of 100 sheets in a bundle of 1000 sheets has the abnormality. This makes it easy to know which handler handled the handle that caused the 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 for example, processing can be 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 explained above, according to the above embodiment, the number of rejected tickets is entered for each predetermined number of sheets, and the number of rejected tickets is temporarily compared, processing of the next paper sheet is started, and the number of rejected tickets is counted again. Since there is no need to insert a classification card, the burden on the operator is reduced. Furthermore, since processing of the next paper sheet is started after a temporary comparison, the non-operating time of the apparatus can be reduced and processing efficiency can be improved. As explained above, according to the present invention, it is possible to provide a paper sheet sorting device with high processing efficiency, which reduces the burden on the operator and reduces the downtime of the device.
