Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a paper sheet sorting device that automatically inspects paper sheets such as slips or tickets and classifies them into valid sheets and invalid sheets.

Recently, banknote sorting devices have been developed that automatically inspect banknotes and classify them into valid banknotes and invalid banknotes.

This sorting device sets a large number of banknotes in a supply section,
By taking out and transporting the set banknotes one by one, the number of banknotes is automatically counted, checking whether there is an excess or deficiency in the number of banknotes, and at the same time checking whether the banknotes are invalid or counterfeit.
Detects different types of notes, expired notes, multiple wraps, torn notes, etc., and makes them more valid, or damaged notes (valid but unsuitable for reissuance).
and genuine notes (tickets that are valid and suitable for reissue),
Each bag is made up of 100 sheets and sealed and stamped.

Many of the invalid tickets that occur during such sorting are those with shapes that are inappropriate for sorting, such as duplicate tickets, torn tickets, and tickets of different types.

Therefore, it is necessary to remove such invalid bills from the conveyance path as soon as possible.If they continue to be conveyed together with normal or damaged bills, they may be misclassified or jammed on the conveyance path.
As a result, not only is the processing capacity reduced, but accurate classification processing becomes impossible.

The present invention has been made in view of the above circumstances, and its purpose is to prevent the occurrence of misclassifications or jams, and to provide efficient and accurate processing almost continuously without reducing processing capacity. An object of the present invention is to provide a paper sheet sorting device capable of sorting processing.

An embodiment of the present invention will now be described with reference to the drawings.

That is, the first function is to accurately count the number of tickets being conveyed and to check whether there are a predetermined number of tickets.

The second function is to detect when two or more tickets are taken out together by the takeout device 2, that is, when they are stacked, because it is impossible to accurately detect and count the tickets. do.

This detection method may be an optical method based on a change in the amount of light transmitted through the ticket, or a method of mechanically measuring and detecting the thickness of the ticket.

The third function is to detect the abnormal approach of the bills taken out by the take-out device 2, since it is impossible to accurately detect and count the bills in the same way as described above.

This detection method is carried out, for example, by detecting the interval between tickets and comparing the interval with a normal interval.

The fourth function is to examine the contents of each incoming ticket one by one and separate invalid bills (counterfeit bills, foreign bills, expired bills, and other suspicious bills) and damaged bills.

This detection method may be any known optical method, mechanical method, or any other method as long as it is effective for achieving the intended purpose.

Furthermore, by incorporating an optical character reading device or the like, it is also possible to read the numbers and separate old tickets from issued years.

In any case, one or more combinations of detection devices are used depending on the purpose.

In this case, each detection device usually returns one sheet as either an invalid ticket, a different type of ticket, a double ticket, a torn ticket, a damaged ticket, or a ticket other than a regular ticket), an unfit ticket, or a regular ticket. You can get it for tickets of.

From these determination results, one determination result is finally given to one ticket according to the priority order shown below.

Reference numeral 6 denotes a sorting device which transfers the tickets that have been conveyed by the conveyance device 3 and passed through the detection section 5 to the first conveyance path 7 or the second conveyance path 8 in accordance with the determination result signal issued by the detection section 5.

That is, when the detection unit 5 outputs a determination result of an invalid note, the corresponding note is guided to the second conveyance path 8, and when a determination result of an unfit note or a normal note is issued, the corresponding note is guided to the second conveyance path 8. It is guided to the first conveyance path 1.

Further, as will be described later, when a sorted card is detected, that card is also guided to the second transport path 8.

The first conveyance path I is branched into a conveyance path 9 for conveying regular bills and a conveyance path 10 for conveying unfit bills, and a sorting device 11 is provided at the branch point.

The conveyance path 9 is branched into a conveyance path 9a that conveys the valid notes to the first valid note stacking section 12a and a conveyance path 9b that conveys the valid bills to the second valid bill accumulating section 12b. A sorting device 13 is provided at the point.

Further, the conveyance path 10 is branched into a conveyance path 10a that conveys the unfit bills to the first unfit note accumulation section 14a and a conveyance path 10b that conveys the unfit bills to the second unfit note accumulation section ↑4b, A sorting device 15 is provided at the branch point.

Each of the stacking units 12a, 12b, 14a, and 14b is for sequentially and orderly stacking the tickets that have been conveyed, and each has a bottom plate 50 that can move up and down. Acts as a device.

Reference numeral 25 denotes a stamping device which displays necessary information such as ``■'', operator code, device number, etc. on the surface of the band wrapped around the handle, and also displays a classification mark to indicate whether the bill is a good bill or a damaged bill.

Reference numeral 26 denotes a stack sorting device which selects a stack stacking section (not shown) in which the stacks of bills are to be stacked depending on the difference between a stack of good bills and a stack of unfit bills.

On the other hand, 27 is a recording device, and in a normal case (when no abnormality occurs), the number of good and unfit bills that flowed before the sorting card is subtracted from the numerical value ``100J'', and the number is subtracted from the second conveyance path 8.
The data is magnetically recorded on the sorting card conveyed by the machine.

This value is the number of tickets that should be stacked in the invalid ticket stacking section 29, which will be described later, assuming that there is no excess or deficiency in the corresponding batch of 100 tickets.

If an abnormality occurs, data indicating the abnormality and the number of the abnormal card are magnetically recorded.

A sorting card detector 31 is provided between the detection unit 5 and the sorting device 6, and detects the timing when the sorting cards, which are sorted into 100 sheets each, pass a predetermined detection position.

This timing becomes the reference timing for count comparison every 100 sheets, which will be described later.

Therefore, it is not allowed to misidentify a regular ticket and a classified card.

For this purpose, for example, the size of the sorted card is made larger than that of a normal ticket so that it can be detected reliably.

This detector 31 uses, for example, an optical device consisting of a light source and a light receiving element, and detects a sorted card by detecting a difference in size.

Further, 32 to 41 are ticket detectors, and 42 to 46 are bundle detectors, each of which is provided at a predetermined position. For example, an optical device consisting of a light source and a light receiving element is used. .

47 is a sorting card issuing device, and 48 is a counting verification device, the details of which will be explained below.

First, the sorting card issuing device 47 handles the banknotes to be sorted (
In addition to recording the necessary data on the bundled paper (called ito obi) that binds the 100 sheets, a card is created by encoding the same data as the recorded data and magnetically recording it on a magnetic tape. This device is configured as follows.

That is, as shown in FIG. 2, there is a frenulum input port 51, a conveying device 52 for conveying the inserted frenulum, a frenulum detector 53 for detecting where the frenulum has passed, and a frenulum detector 53 for detecting the place where the frenulum has passed. A printer 54 for digitally recording the data, tape reels 55a and 55b for supplying tape that holds the frenulum on which data is recorded, and a winder for winding up the tape holding the frenulum and storing the frenulum. A reel 56, a magnetic tape reel 51 that supplies magnetic tape, a sorting card reel 58 that supplies a strip-shaped sorting card holding the magnetic tape, and a magnetic tape is attached to the supplied strip-shaped sorting card to a predetermined length. A cutter device 59 that cuts the cut sorted cards into strips, a magnetic recording device 60 that encodes and magnetically records the same data as the data recorded on the frenulum on the magnetic tape of the cut sorted cards, a sorted card detector 61, a sorted card conveyance path 62, and It consists of a sorted card ejection port 63.

Note that the detectors 53 and 61 are optical ones consisting of a light source and a light receiving element, for example.

The operation of the sorting card issuing device 47 constructed in this way will be explained with reference to the control circuit shown in FIG.

First, the operator removes the frenulum binding the banknotes to be sorted from the bundle, and inserts the frenulum into the slot 51.

Normally, the transport device 52 is in operation and the frenulum is transported.

When the frenulum is detected by the detector 53, the signal is applied to the transport device control circuit T2 via the OR circuit 71, and the control circuit 72 stops the operation of the transport device 52.

When a frenulum is detected, a signal from the control circuit 72 causes the data control circuit 73 and the print control circuit 74 to
operates, data is read from a data memory (not shown), and output from the print control circuit 74 and the AND circuit 75.
The logical product is taken.

As a result, the printer 54 records predetermined data on the frenulum.

The contents of this recorded data are determined by supplying the output of the AND circuit γ5 (data read from the memory) and the data supplied from the printer 54 to the check circuit 77 via the AND circuit 16, where the two are compared and checked. By doing this, it is checked whether or not it has been recorded correctly.

As a result of this check, if there is no abnormality, the signal is NOT
The data is supplied to the control circuit 72 via the circuit 18 and the OR circuit 79, and the conveying device 52 operates again to convey the data-recorded frenulum and send it to the take-up reel 56.

Further, as a result of the above check, if there is no abnormality, the card conveyance path control circuit 80 operates, the card conveyance path 62 is driven, and magnetic tape is pasted on the strip-shaped classified card and cut into a predetermined size.

Note that at this time, the data read by the control circuit 73 is supplied to the data conversion circuit 82 via the AND circuit 81, encoded here, and supplied to the AND circuit 83.

When the sorting card is detected by the detector 61, the signal, the output of the control circuit 80 and the data conversion circuit 8
The logical AND with the output of 2 is established in the AND circuit 83.

As a result, the magnetic recording device control circuit 84 operates, and the recording device 60 magnetically records data on the magnetic tape of the classification card.

Thereafter, in order to check whether the data recorded on the sorting card is correct, the above data is read by the magnetic reader 85, and the read data is sent to the data conversion circuit 8.
The sorted card is supplied to the check circuit 87 through the AND circuit 86 along with the output (written data) of step 2, and while the read data and the written data are compared and checked, the sorted card is ejected out of the device from the ejection port 63. .

As a result of the above check, if there is no abnormality, the signal is NOT
The signal is supplied to the control circuit 72 via the circuit 88 and the OR circuit 79, and the transport device 52 is driven again.

This is to receive the next frenulum. Further, as a result of the above check, if there is no abnormality, the reel control circuit 89 operates and the reel drive device 90 operates.

As a result, the tape reels 55a, ssb and the take-up reel 56 are driven, and the frenulum on which the data is recorded is stored on the take-up reel 56.

On the other hand, if an abnormality is detected as a result of the check in the check circuits 77 and 87, the conveying device 52 is operated in the opposite direction to return the frenulum to the frenulum input port 51 in order to record correct data again.

At the same time, a display device (not shown) displays that the frenulum needs to be reinserted.

A typical example of the frenulum in this classification card issuing device 41 is shown in FIG. 4, and a in the figure is recorded data.

An example of a sorted card issued by this sorted card issuing device 47 is shown in FIG.

That is, a magnetic tape 92 is attached to one end of the sorting card 91 in the longitudinal direction, and each piece of data is encoded and recorded on this tape 92.

For example, b in the figure is data corresponding to the data recorded on the obi, C is data indicating the presence or absence of an abnormality, d is data indicating the number of the abnormal card, and e is the data corresponding to the data recorded on the obi. This is data indicating the number of tickets that should be included.

The width W of the card 91 is, for example, about 20 mm wider than the width of the bank note, and the length L is set to be the same as the length of the bank note.

In addition, the count verification device 48 divides the number of tickets that have been sorted into 1
This is a device that counts and collates the number of tickets in units of 00 and verifies whether there is an excess or shortage of tickets, etc., and is configured as follows.

That is, as shown in FIG. 6, there is an input slot 101 for inserting sorted cards and tickets, a conveying device 102 for conveying the inserted sorted cards and tickets, a reading device 103 for reading data recorded on the sorted cards, and a device for reading the data recorded on the sorted cards. A counting device 104 that detects and counts the tickets that come, a sorting device 105 that sorts sorted cards and tickets, a card stat force 106 that accumulates sorted cards, a postmark device 107 that puts a postmark on the tickets, and a counter similar to the counting device 104 described above. A device 108, a stacking unit 109 for stacking tickets, a sorting paper roll 110 for holding sorting paper for sorting tickets into 100 pieces, a cutter device 111 for cutting the sorting paper into required lengths, and a cutting device 111 for cutting the sorting paper into required lengths; It is composed of a conveyance path 112 for conveyance.

The operation of the count verification device 48 configured in this way will be explained.

First, when a start switch (not shown) is turned on, the transport device 102 starts operating.

Next, the sorted card is first inserted through the slot 101.

This card records the number of tickets to be supplied, and the data is transferred to the reading device 10 during transportation.
3, the data is stored in a counter (not shown).

Thereafter, the card is transported to the card stacking station 106.

After this, tickets are inserted into the slot 101 one by one.

When a ticket is inserted, it is counted by counting devices 104 and 108, respectively, and the ticket is accumulated in a stacking section 109.

Note that when 100 tickets are stacked in the stacking section 109, the sorting paper roll 110 is operated, and the paper is cut into a predetermined length and placed on top of the 100th ticket.

This allows the classification of 100 tickets to be determined from the outside.

However, when a stop switch (not shown) is pressed when all the tickets to be processed have been inserted, the operation of the device is stopped.

At this time, by comparing the count contents of the counting devices 104 and 108 with the contents of the counter storing the data read from the cards, it is possible to perform verification in units of 100 cards.

As a result of this comparison, if the values on the counting devices 104 and 108 are equal to the value on the counter, this is displayed and the conveying device 102 operates again to accept the different sorted card.

Further, if the above values are not equal, this is displayed and the device is locked so that it cannot operate.

Next, the counting circuit used in this sorting device will be explained.

Of the supplied tickets, this counting circuit calculates the correct bill accumulating section 12a,
12b and the unfit note accumulating parts 14a and 14b, respectively, and compare the sum of the number of bound notes B and the number of unfit notes with a predetermined value, the invalid note accumulating part 29
This is a device for calculating the number of tickets that should be held at a time, and is configured as shown in FIG.

That is, assuming that the number of tickets currently supplied is the same as the set value H, the invalid ticket stacking unit 29 and the valid ticket stacking unit 12
The sum of the numbers of bills that are sorted and accumulated in the a, 12b, and unfit note accumulation sections 14at14b is H.

The output of the detection circuit 121 connected to the ticket detector 35 is AN
D circuit 122a. Total number counter 12 via 122b
3a and 123b, and the output of the detection circuit 124 connected to the ticket detector 36 is connected to AND circuits 125a and 125.
A detection circuit is connected to the total number counters 126a and 126b through the terminals b, and is connected to the ticket detector 37. The output of 127 is connected to total number counters 129a, 129b via AND circuits 128a, 128b.

On the other hand, the detection circuit 13 connected to the sorting card detector 31
The output of 0 is connected to the timing signal generation circuit 131.

Timing signals are supplied from this timing signal generation circuit 131 to count control circuits 132, 133, and 134, respectively, and these control circuits 132, 133, and 134 control counters 123a, 126a, 129a, and 123.
b, 126b, and 129b operate alternately.
ND circuit 122at122bt125a, 125b, 1
28ay128b is controlled.

After a certain period of time has elapsed since the sorting cards passed through the sorting device 6, counters 126a, 126b and 129b, 129b
are supplied to an adder 136 via a gate circuit 135 and added, and the result is supplied to a comparator 137ζ.

This comparator 137 also includes counters 123a, 12
The contents of 3b are supplied via gate circuit 138 and are compared with the output of adder 136 and counters 123a and 123b.

As a result of this comparison, if there is a mismatch, the device is in an abnormal state, and the mismatch indicator 139 displays a mismatch.

The gate circuits 135 and 138 are controlled by a collation control circuit 140 connected to the timing signal generation circuit 131.

If the results of the above matching match, the arithmetic circuit 141 calculates the counters 123a and 123 from the set value H.
subtract the contents of b, supply the result to the recording device 27,
Record the above calculation results on the classification card.

The output value of the arithmetic circuit 141 should be the number of invalid tickets, and if you actually count the number of invalid tickets and compare that value with the calculation result of the arithmetic circuit 141 recorded by the recording device 27, The number of supplied tickets can be known, and the extent to which the number differs from the set value H can also be determined.

The above verification is performed every time a sorted card passes through the card detector 31.

In this case, two sets of counters, namely 123a, 126a
, 129a, 123b, 126b, and 129b, verification is automatically performed without stopping the ticket transport.

Next, a method for checking the number of tickets sorted and stacked in each stacking section will be explained.

When the value of the valid bill sorting counter 142, which receives a signal from the bill detector 36 and counts it, reaches a set value, for example, 100 bills,
A signal is output from the comparator 143 and the sorting device control circuit 1
44 and the sorting device drive circuit 145, the sorting device 13
is driven, and the supplied tickets are sorted and stacked in the other stacking section.

Now, suppose that the sorting device 13 is switched so that 100 bills are first stacked in the first stacking section 12a and then stacked in the second stacking section 12b. D (100 in this example) and counters 147, 14
Counter 1 selected by control circuit 144 among 8
The contents of 48 are compared.

As a result of this comparison, if they match, the stacking section control circuit 149 immediately drives the bottom plate 50 of the first genuine bill stacking section 12a via the drive circuit 150a, and the 100 bundles are carried out.

The operation of the comparator 146 and the control circuit 149 is performed in accordance with a timing signal output from a timing signal generation circuit 151 which operates in accordance with the output of the comparator 143. ,
At the time when the operation of the first valid bill accumulating section 12a is completed, the valid bill counter 152 is incremented by "+100".

If there is a mismatch in the comparator 146, the incorrect classification indicator 1
53 is activated and the device goes into an abnormal state.

Note that the counters 147 and 148 are ticket detectors 38 and 39.
The outputs of the detection circuits 154 and 155 connected to the circuits 154 and 155 are respectively counted.

Further, the output of the control circuit 144 is supplied to an integrated unit selection circuit 156, and this selection circuit 156 selects the integrated unit driving circuits 150a and 150b.

Also, the selection circuit 156 selects counts 147 and 148.
The content of the counter 142 is selected and extracted, and compared with the content of the counter 142 by a comparator 157. If there is a mismatch, a mismatch indicator 15 is displayed.
8 is activated.

Then, the contents of the counter 147 or 148 selected by the selection circuit 156 are stored in the storage device 159.

On the other hand, similarly, the detectors 40 and 41 have detection circuits 160 and 1.
61 are connected to each other, and the outputs of the detection circuits 60 and 161 are counted by counters 162 and 163,
In the same manner as in the case of the genuine notes, the first one is sorted by the sorting device 15.
Switching control is performed for the second unfit note accumulating unit 14a and the second unfit note accumulating unit 14b.

In this case, the unfit bill counter 164 is incremented by "+100" when the operation of the accumulating section 14a (14b) is completed.

Further, the contents of the counter 162 or 163 are selected by the integrated section selection circuit 165 and stored in the storage device 166.

Therefore, in the event of an abnormal condition such as a jam, a shift error, or a count discrepancy, all normal bills and unfit bills in the unfit bill stacking section can be removed without having to be re-supplied.
By adding up the number of tickets in the invalid ticket accumulation unit 29 and checking the total number, the specific number of supplied tickets,
For example, check 100 sheets.

The number Q of invalid tickets in the invalid ticket accumulating section 29 in a normal case is Q=H−G
l(G2) However, H...Set value Gr(G2)...Total number counter 123a (123b
), whereas the total number of valid and unfit bills taken out from the stacking sections 12a, 12b, 14a, 14b and the number of tickets in the invalid bill stacking section 29 when an abnormal condition occurs The sum is expressed as:

(1) If an abnormal condition occurs when only the same grip is being supplied Q=H-G+RA+RU-PA-PU However, G...G1+G2 RA...Contents of storage device 166 RU...Storage Contents of device 159 PA...Contents of counter 164 PU...Contents of counter 152 (2) When an abnormal state occurs when the nth and (n+1)th lumps are being supplied Qn=H-Gn+RA 10RU-PA-PU+G(n+1

In the figure, 171 is a memory circuit for storing abnormal conditions when they occur, 172 is an arithmetic control circuit, and 173 is an arithmetic circuit, in which the set value H and the respective counters 123a,
123b, 164, 162, 152, and storage device 1
The contents of 66 and 159 are respectively supplied, and the above calculation is performed to output the answer (Q, Qn, Qn+1).

Next, the ticket shift circuit used in this sorting device will be explained.

This ticket shift circuit is a circuit that shifts the determination result output from the detection unit 5 according to the conveyance of the corresponding ticket and controls the sorting devices 6 and 11, and is configured as shown in FIG. There is.

That is, 181, 182, 183, and 184 are timing signal generation circuits connected to ticket detectors 32, 33, 34, and 35, respectively;
, 184 generate timing signals T1 to T4, respectively.

Each of these timing signals T1 to T4 is transmitted to the shift register 1.
J-K type flip-flop circuits (hereinafter simply referred to as FF circuits) 185a and 185 that constitute 85 and 186;
b, 185c and 186a, 186b, 186c, 1
86d, and shift check circuit 1.
87a, 187b, 187c and 188a, 188b
, 188c, and 188a as timing signals.

Further, 189 is an invalid ticket determination circuit of the detection unit 5, and its output is the input of the shift register 185, that is, the FF circuit 185a.
is supplied to the J and K input terminals of.

Further, 190 is an unfit note judgment circuit of the detection unit 5, and its output is the input of the shift register 186, that is, the FF circuit 186a.
is supplied to the J and K input terminals of.

Thus, the invalid ticket determination circuit 189 sets the FF circuit 185a to the "1" state if the ticket being conveyed is not invalid.

That is, when the leading edge of the ticket reaches the ticket detector 332, the timing signal generation circuit 181 outputs the timing signal T1, which clears the FF circuit 186a of the shift register 186, and then clears the FF circuit 186a of the shift register 186 with the timing signal T2. Data output from the shift register 189 is set in the FF circuit 185a of the shift register 185.

Next, the check circuit 181a checks whether the above data has been set reliably using the timing signal T3.

If the shifted data is different as a result of this check, the shift register 185 is cleared.

Furthermore, the timing signal T4 is a signal that clears the FF circuit that has been shifted, that is, the FF circuit in the previous stage.

Next, when the leading edge of the ticket reaches the ticket detector 33, a timing signal T} is generated from the timing signal generation circuit 182 in the same manner as described above.
-T4 is output, the contents of the FF circuit 185a constituting the shift register 185 are shifted to the FF circuit 185b, and the contents of the previous stage FF circuit 185a are cleared by the signal T4.

In addition, 191 is an FF for remembering the presence or absence of a classification card.
When a card is detected by the card detector 31, a signal is output from the detection circuit 192, and the FF circuit 191 is set by the signal.

When this FF circuit 191 is set, the FF circuit 185
Even if the content of b is ``1'' or ``0'', the subsequent FF
An "O" signal is set in the circuit 185c.

Further, this FF circuit 185C is set when the leading edge of the ticket reaches the ticket detector 34, and controls the drive circuit 193 that drives the sorting device 6 according to the contents.

That is, when the content of the FF circuit 185c is "0",
The sorting device 6 is controlled so that the tickets are conveyed to the invalid ticket stacking section 29.

On the other hand, the unfit note determination circuit 190 outputs a "1" signal when the transferred note is not an unfit note.

Therefore, the FF circuit 186a of the shift register 186
is the timing signal T2 output from the timing signal generation circuit 181 when the tip of the ticket reaches the ticket detector 32.
When the note is unfit, it is set to ``(09'', and when it is not an unfit note, it is set to ``1'', and thereafter the shift register 1 is set in the same way.
The contents are sequentially shifted within 86.

After that, the tip of the ticket reaches the ticket detector 35 and the FF circuit 1
When data is set in 86d, the drive circuit 194 that drives the sorting device 11 is controlled according to the contents.

That is, when the content of the FF circuit 186d is "0",
The sorting device 11 is controlled so that the bills are conveyed to the unfit bill stacking section 14a (14b).

Here, the contents written to the shift registers 185 and 186 treat the "0" signal as a meaningful signal.

This is done with safety in mind when transporting tickets.

In other words, if the signal disappears due to the influence of external noise while the "1" signal is being shifted in the shift register, the ticket must be sorted into a collection section with a higher sorting priority. No.

For example, if a bill with an unfit bill signal loses its signal, it will be sorted and stacked in the invalid bill stacking section 29.

In addition, the FF circuit 185C of the shift register 185 is
'', that is, the sorting device 6 transfers the ticket to the invalid ticket accumulation section 29.
For example, when a ticket passes the ticket detector 34a while the ticket is being conveyed in the direction of conveyance, the shift error check circuit 19
5 operates and performs a check.

A bill detector 36 is also connected to this check circuit 195, so that a check is similarly performed when unfit bills are conveyed to the valid bill stacking sections 12a and 12b.

Note that 196a to 196h in FIG. 9 are OR circuits, respectively.

Next, the bundle shift circuit used in this sorting device will be explained.

When each stacking unit is driven, this bundle shift circuit holds a signal indicating that the bundle is a good bill or a damaged bill, and sequentially shifts the signal to send the stamping device 25 to the corresponding bundle according to the signal. This is a circuit that stamps a stamp on the band and controls the bag sorting device 26 to sort and accumulate the bags in the stacking section of each bag, and is configured as shown in FIG. 10.

That is, 201 is the bottom plate 50 of the first genuine bill accumulating section 12a.
202 is the first genuine bill accumulating unit and driving circuit that drives the second
The outputs of the respective drive circuits 201 and 202 are supplied to shift registers 204 and 205 via an OR circuit 203.

The shift register 204 includes J-K type flip-flop circuits (hereinafter simply referred to as FF circuits) 204a, 204.
b204c, 204d, and 204e, and the input of this shift register 204, that is, the first stage FF circuit 204a
The output of the OR circuit 203 is supplied to the J terminal of the circuit.

Further, the shift register 205 has an FF circuit 205a.
, 205b, 205e, 205d, 205e,
The output of the OR circuit 203 is supplied to the input of this shift register 205, that is, the input terminal of the first stage FF circuit 205a.

206 is a first unfit note accumulating unit driving circuit that drives the bottom plate 50 of the first unfit note accumulating unit 14a, and 207 is a second unfit note accumulating unit driving the bottom plate 50 of the second unfit note accumulating unit 14b. In the drive circuit, the output of each of the drive circuits 206 and 207 is supplied via an OR circuit 208 to the K input terminal of the first stage FF circuit 204a and the J input terminal of the FF circuit 205a that constitute the shift registers 204 and 205. .

In addition, each grip detector 42, 43, 44, 45, 46 has
Detection circuits 209, 210, 211, 212, 2, respectively
13 to the timing signal generation circuits 214, 215,
216, 217, and 218 are connected, and the timing signals generated by each of the signal generation circuits 214 to 218 are supplied to shift registers 204 and 205.

Now, however, the drive circuit 201 drives the bottom plate 50 of the first genuine bill stacking section 12a, and the bundle of 100 genuine bills is carried out to the loquat conveying device 17, and the bundle is conveyed to the bundle detector 4.
2, a signal is supplied from the detection circuit 209 to the timing signal generation circuit 214, and this signal generation circuit 214
A timing signal is output from I to the FF circuit 204a.
The "I" signal is set to the FF circuit 205a, and the "O" signal is set to the FF circuit 205a.

This signal is transmitted to FF circuits 204b, 205b, and 204c, respectively, when a valid stack of bills reaches the stack detectors 43 to 46 in sequence.
and 205c, 204d and 205d, 204e and 205e
and finally the FF circuits 204e and 205
A valid bill signal is supplied to the stamping device control circuit 219 and the folding device control circuit 220 by the output of e.

As a result, the authentic bill display is not stamped by the stamping device 25,
The sorting device 26 collects the correct bills in the stacking section.

On the other hand, when the bundle of unfit bills is taken out from the unfit bill stacking section 14a or 14b, an "O" signal is set in the FF circuit 204a, a "1" signal is set in the FF concave path 205a, and the subsequent shift operation is performed as in the above case. The same is done.

Also, if the bundle is transported, the FF circuit 204
When the "J" or "0" signal is set to both a and 205a, the grip shift check circuits 221 and 22
2, 223, and 224 operate, and each FF circuit 20
Clear 4a-204e and 205a-205e.

Therefore, since the bundle at this time does not have a signal, the unfit note indication is finally stamped and the bundle is 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 note.

In addition, the time during which the bundles are conveyed between each of the bundle detectors 42 to 46 is approximately constant, and if a problem such as dissipation or not being physically transported occurs, the time for conveying the bundles between each of the bundle detectors 42 to 46 is approximately constant.
Grip jam check circuits 226, 227 provided between
228 and 229.

This checking method measures, for example, the transportation time of the bundles between each of the bundle detectors 42 to 46, and detects a jammed status if the time is shorter than a predetermined fixed time or longer than a fixed time. do.

Note that it is possible to input bundles from the collection device 20 solely for the purpose of bundling, but in this case, for the reason mentioned above, the bundles do not have a signal, so they are treated as unfit bills, and the unfit bills display is stamped. The unfit notes are collected in the unfit note stacking section.

Further, the timing signal outputted from the timing signal generation circuit 214 is supplied to a direction changing device control circuit 230, which controls the direction changing device 18.
is controlled.

Furthermore, the timing signal output from the timing signal generation circuit 216 is supplied to the procurement device control circuit 231, and the procurement device 20 is controlled by the control circuit 231.

Further, the timing signal output from the timing signal generation circuit 217 is supplied to the sealing device control circuit 232,
The sealing device 21 is controlled by this control circuit 232.

In addition, 233a to 2331 in FIG. 10 are OR respectively.
It is a circuit.

Next, a jam detection circuit used in this sorting device will be explained.

This jam detection circuit is a circuit that immediately detects such a condition in order to prevent damage to the device if any failure occurs during the transportation of one ticket.
It is constructed as shown in FIG.

That is, 241, 242, 243 are ticket detectors 34, 3
4a and 34b, the output of this detection circuit 241 is supplied to a jam check circuit 244, and the output of each of the throttling circuits 242 and 243 is supplied to a check circuit 244 via an OR circuit 245. I can be killed.

This check circuit 244 also includes a time setting circuit 24.
6 outputs are provided.

At the sorting device 6, the ticket is detected by the ticket detector 34.
The check circuit 244 checks the time from when the ticket passes through the ticket detector 34a or 34b to the ticket detector 34a or 34b, and if the time is longer than a preset fixed time, it is determined that the ticket is jammed at the sorting device 6. Upon determination, a signal is output from the check circuit 244, and the jam indicator 241 displays it.

Further, 248 is a detection circuit connected to the ticket detector 35, and the output of this detection circuit 248 is the jam check circuit 2.
49a, 249b, 249c, respectively, and these check circuits 249a, 249b, 249c,
The outputs of time setting circuits 250a, 250b, and 250c are respectively supplied.

The respective outputs of the check circuits 249a, 249b, and 249e are supplied to a jam indicator 252 via an OR circuit 251, respectively.

However, at the sorting device 11, the ticket is detected by the ticket detector 3.
5 is checked by the check circuit 249a, and if the time is longer than a predetermined time, it is determined whether the ticket has jammed in the sorting device 11 or not.
Alternatively, it is determined that two or more tickets have been conveyed in succession, and a signal is output from the check circuit 249a, which is displayed on the jam indicator 252.

In addition, the check circuit 249b checks the time it takes for the ticket to pass through the winding detector 35, and if the time is shorter than a predetermined time, it is determined whether the ticket is skewed or not.
Alternatively, it is determined that something other than a ticket has been conveyed, and a signal is output from the check circuit 249b, and the jam indicator 2
52 displays it.

Furthermore, the check circuit 249C checks the time interval between a ticket passing through the ticket detector 35 and the next ticket, and if the time interval is shorter than a predetermined time, the interval between tickets is shortened. When it is determined that there is too much jam, a signal is output from the check circuit 249c, and the jam indicator 252 displays it.

Furthermore, the same circuits as in the case of the ticket detector 35 are connected to the other ticket detectors 36 to 41, respectively, so that the same three types of checks as described above are carried out, and if a jam etc. occurs, it is displayed. It has become.

Next, the overall operation of the sorting device according to the present invention will be sequentially explained with reference to the flowchart shown in FIG.

Note that each flow in this flowchart is divided as shown on the left side of the figure.

In addition, 1000 banknotes to be sorted in this explanation is 1
Each piece of paper is tied together with a frenulum, which is called a ``bundle.''

Every 10 pieces of these bundles are tied together with a large obi, which means "
called a bundle.

(1) Take out the bundle and remove the large obi.

(2) Remove one of the ten frenulums and insert the frenulum into the slot 51 of the sorted card issuing device 47.

(3) The classification card issuing device 47 digitally records and displays a predetermined number on the surface of the frenulum and stores this frenulum on the take-up reel 56.

On the other hand, the same number as the number recorded and displayed on the frenulum is encoded and magnetically recorded on the created classification card.

Thereafter, the sorted card is ejected from the card ejection port 63, and the issuance of the sorted card is completed.

(4) The card issued by the classification card issuing device 47,
The frenulum in (2) above is inserted into the rear end of the removed handle and stored in the magazine.

(5) When all bundles (10 in this example) have been stored in the magazine while inserting sorting cards, the preparation of that magazine is complete, and the bundle for the next magazine is prepared, and ).

(6) Set the magazine in the supply section 1.

(7) The supply unit 1 pushes out the tickets in the magazine to the takeout device 2 side.

(8) The tickets are sequentially taken out one by one from the supply section 1 by the takeout device 2.

(9) When the taken-out note passes through the detection unit 5, the condition of the note is detected, and it is determined whether the note is a stolen note, a counterfeit note, a different type of note, an expired note, a valid note, a damaged note, etc.

(lO) When determining the detection result for a ticket, one determination result signal is given to the ticket according to the priority order.

(11) This determination result signal is shifted by a ticket shift circuit, and in front of each sorting device 6, 11, the opening/closing direction of the sorting device is determined according to the signal, and the ticket is guided in that direction.

(l2) The sorting device 6 guides invalid notes (notes other than normal notes and unfit notes) to the invalid note accumulation section 29.

(l3) The normal and unfit bills reach the sorting device 11, where they are sorted into normal and unfit bills by the shift signal in the same manner as described above.

(l4) Tickets passing through this sorting device 11 are transferred to the counter 12.
3a (123b) (l5) The tickets sorted into regular bills by the sorting device 11 are counted by the counter 142 in front of the sorting device 13, and every 100 bills are counted in the sorting direction of the sorting device 13, that is, the first , the second genuine bill accumulating sections 12a and 12b are switched.

(l6) In the population of the genuine bill accumulation section 12a (12b),
The number of tickets entering there is counter 147 (14B)
is counted by.

(17) The bills sorted into unfit bills by the sorting device 11 are postmarked by the postmark device 16 and counted by a counter in front of the sorting device 15. , second genuine bill accumulating section 14a, 14b
Switch.

(l8) When the stacking section into which the bills flow is switched when 100 normal or unfit bills are stacked, the bottom plate 50 of the stacking section where 100 bills are stacked operates, and the 100 bills are placed on the bundle conveyance device 17. The bundle is carried out and conveyed to the direction changing device 18.

(l9) The grip that has reached the top of the direction changing device 18 is now 9
The direction is changed by 0° and then conveyed to the collection device 20.

(20) The bundles that have reached the top of the collection device 20 are arranged into a rectangular shape, including bundles that are poorly stacked, and are conveyed to the sealing device 21.

(21) The bundle that has reached the sealing device 21 is sealed here, and the necessary information is stamped and displayed by the next stamping device 25, and a genuine note is placed on the surface of the sealed paper by the shift and signal from the bundle shift circuit. Or, unfit notes are marked separately.

(22) The bundle displayed on the stamping device 25 is
6, the bills are divided into good and unfit bills and guided to the stacking section.

(23) On the other hand, since the tickets in the supply unit 1 are sorted into batches (100 pieces) by sorting cards, when this sorting card is taken out, the card detector 31 detects its presence.

(24) As a result, the sorting device 6 guides the sorted card to the invalid ticket accumulation section 29.

(25) Even if a sorted card and the tickets in the bundles before and after it overlap, the card detector 31 reliably detects the sorted card.

(25) The recording device 27 provided in front of the invalid note accumulating unit 29 records that the note before the classification card is stored in the second unfit note accumulating unit 14b.
The classification card is set so that it is located at the point where the classification card passes when the counting has been checked and the number to be recorded has been calculated.

That is, when the sorted cards pass through this recording device 27, the number of cards that should be in the invalid ticket accumulation section 29 is recorded, assuming that 100 cards are to be sorted.

Furthermore, when an abnormal condition occurs, the number of the related abnormal card is recorded.

(27) The thus recorded data is confirmed by the reading device 28 and the card is then accumulated in the invalid ticket accumulation section 29.

(28) If a jam occurs in the sorting device or the stacking unit, or if a shift error occurs in the sorting device 6, the jam detection circuit detects this and stops the conveyance of tickets.

In this case, since the location where the problem occurred is displayed, the ticket at that location is corrected or taken out, and then all the tickets on the conveyance path are accumulated.

At this time, the take-out device 2 is brought into a stopped state.

(29) 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 tickets is stopped, and the tickets on the conveyance path are stacked in the stacking section.

(30) After (28) and (29) above, all the tickets are taken out from each stacking section and placed in the take-home ticket box 30.

G31) When an abnormal condition occurs as described above, it will be displayed, so manually write the displayed data (number) on the abnormal card and insert one card from the insertion device 4, and the abnormal card will become an invalid ticket. After being accumulated in the accumulation section 29, the abnormal card is taken home from there and placed on the top of the take-home ticket box 30.

This is to record the number of sheets that could not be recorded on the classification card in this abnormal card.

(32) After completing the process in (31) above, start supplying again.

(33) If a recording error occurs in (27) above, the conveyance of the tickets is stopped, and then all the tickets on the conveyance path are stacked in a predetermined stacking section.

Thereafter, the classified card that has been recorded incorrectly is pulled out from the invalid ticket accumulating unit 29, and one card is inserted from the insertion device 4 and recorded again.

After this process is completed, the supply is restarted. (34) When the invalid ticket accumulation section 29 or take-home ticket box 30 is full of tickets, the take-out device 2 is stopped and the dividing point of the bundle, that is, the sorting card is issued, the invalid ticket accumulating section 29
Or remove the take-home ticket box 30.

When the take-out device 2 is stopped in the middle of a bundle, the remaining rolls and classification cards of the bundle are extracted from the supply section 1 and conveyed from the one-sheet input device 4.

Note that after removing the stacking section 29 or box 30, an empty stacking section 29 or box 30 prepared in advance is set.

(35) Take out the top sorted card from the removed invalid ticket stacking section and feed it manually through the input port 101 of the counting and verification device 48.

Next, the tickets above the next classification card are inserted into the slot 101 one by one while inspecting the contents (false ice tickets, old tickets, expired tickets, etc.).

After supplying all the tickets until the next classification card arrives, the supply is stopped.

(36) The supplied sorted cards are read by the reader 103 for the number, data indicating the presence or absence of an abnormality, the number of cards, the number of the abnormal card, etc., and the sorted cards are stacked in the card stacker 106.

In addition, the read number, presence or absence of an abnormality, and the number of the abnormal card are displayed.

(37) Usually, the supplied tickets are counted by the counting devices 104, 10.
It is counted by 8 and accumulated in the accumulation section 109.

(38) There is a postmark device 107 at the entrance of the stacking section 109, by which a postmark is stamped on the pass ticket.

(39) A sorting paper is inserted for every 100 tickets to be stacked in the stacking section 109.

In this manner, by supplying the separated bills into 100-sheet units from the sealing device 21 of the main body of the apparatus, the bills are sealed, stamped, and displayed, and classified as a bundle of unfit bills.

(40) When the supply is stopped in the above (35), the number of tickets supplied after the sorted card is counted by the counting device 104, 108.
This can be known from the content of the number of cards, and this is calculated with the number of cards read from the sorted cards to perform a count comparison of 100 cards.

As a result of this verification, if there are no excess or shortage of 100 cards, the transport device 102 is driven to receive the next sorted card.

If there is an excess or shortage of 100 cards, the total number of cards included in the bundle is displayed and the device is locked, making it impossible to check the next classification card.

(41) If the above-mentioned surplus or deficiency occurs, search for it from the frenulum stored in (8) above according to the number of the classification card.

This makes it possible to know the condition of the grip where frenulum or excess or deficiency has occurred.

(42) Similarly, if a suspicious ticket is found in the content inspection of the layered ticket (35), the supply will be stopped.

This results in a situation where the number of sheets is insufficient.

(43) The device lock in (41) and (42) above can only be cleared with a key owned by the supervisor.

(44) If it is displayed that there is an abnormality when the classification card is fed, then the abnormality card of the related number is continuously fed.

Thereby, even if the number of cards is not recorded on the classified card, it can be read from the abnormal card.

(45) First, the tickets in the invalid ticket stacking section are inspected and supplied one by one, and when the supply is finished, the supply is stopped, resulting in a shortage of tickets, and the shortage of tickets is displayed.

The tickets found on the abnormal card are counted using a normal counter, and if the value matches the displayed number, the verification is OK; if they do not match, it means that there is an excess or deficiency in the number of tickets.

As explained above, according to the above embodiment, the detection unit 5 determines whether the note is a genuine note (first paper sheet), an unfit note (second paper sheet), or an invalid note that is not recognized as such. By doing so, the sorting device 6 first sorts invalid bills, and then the sorting device 11 sorts them into good bills and unfit bills, so that the invalid bills are removed from the main conveyance path first. There is no possibility that the bills will continue to be conveyed together with good or unfit bills, and missorting or jamming can be reliably prevented.

In other words, as mentioned above, invalid tickets are often in shapes that are inappropriate for sorting, such as duplicated tickets, damaged tickets, and tickets of different types, so these should be sorted first and removed from the main conveyance path. This can prevent the occurrence of errors, misclassifications, jams, etc.

Moreover, with the above-described configuration, a series of processes from supplying tickets to sealing each predetermined number of tickets to stamping and displaying necessary information on the sealing band can be performed continuously and automatically. Processing can be speeded up, the labor-saving effect can be significantly improved, and the burden on the operator can be reduced.

Although the above embodiment describes the case where banknotes are sorted, the present invention is not limited to this, and can be similarly applied to sorting of other paper sheets such as securities or slips. can.

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, the detection unit determines whether the paper sheet is the first paper sheet, the second paper sheet, or a paper sheet that is not recognized as such. By separating the paper sheets that are not recognized as the second paper sheets, and then separating them into the first paper sheets and the second paper sheets, the first
Alternatively, the configuration is such that paper sheets that are not recognized as second paper sheets are removed from the main conveyance path first, which prevents misclassification or jams from occurring, which may lead to a reduction in processing capacity. Continuous, efficient and accurate sorting processing is possible without any problems.

Furthermore, with the configuration of the present invention, a series of processes from supplying paper sheets to sealing each predetermined number of sheets to stamping and displaying necessary information on the sealing strip can be performed continuously and automatically. , various effects can be expected.
