Description

[Detailed Description of the Invention] The present invention... Takie relates to a paper sheet sorting device that automatically inspects paper sheets such as slips or bank notes and sorts them into reusable sheets and non-reusable sheets.

Recently, a banknote sorting device has been considered as this type of sorting device.

This banknote sorting device. Place the banknotes to be sorted into the supply section. The set banknotes are taken out one by one, and the taken out banknotes are inspected as necessary while being transported, and then reusable banknotes (valid and suitable for reuse) are determined according to the specified conditions. In banknotes (hereinafter referred to as genuine notes)
．． Non-reusable banknotes (banknotes that are valid but not suitable for reuse; hereinafter referred to as unfit notes). and invalid banknotes (banknotes other than genuine and undamaged banknotes, such as counterfeit banknotes, mismatched banknotes, and stacked banknotes, hereinafter referred to as invalid banknotes). Among these classified banknotes, both good and unfit notes are counted and checked for excess or deficiency in number. Based on the count, separate and accumulate every 100 sheets,
The 100 sheets of normal and unfit bills thus sorted and stacked are each sealed into a bundle, and a predetermined seal is affixed to the bundle.

As is well known, the undamaged note bundles sealed as described above are incinerated in a furnace, etc., but before being incinerated, a punch is used to punch out designated areas of the unfit note bundles, such as numbers. By punching a hole in the area where a mark or signature is written, the unfit note is invalidated so that it cannot be reused, and it is easy to handle it after expiration. (requires strict storage).

Conventionally, unfit bill bundles are accumulated once and then manually fed to the punching machine, so the unfit bill bundles taken out from the sorting device must be handled more strictly. There is a need. Furthermore, there were other problems such as the process of expiration of unfit notes being extremely troublesome and inefficient.

The present invention has been made in view of the above circumstances, and its seventh purpose is to automatically process the expiration of unreusable paper sheets by this device itself, and to disable the subsequent use of unreusable paper sheets. It is an object of the present invention to provide a paper sheet sorting device that can be easily handled.

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

In Figure 1, 1 is the supply section. A magazine is set here in which a sorting card (to be described later) is inserted into every 100 banknotes to be sorted (hereinafter simply referred to as "notes") as they age. When the device starts its sorting operation, it supplies the ticket to the take-out device 2.

The extraction device 2 is. The tickets (and sorted cards) set in the supply section 1 are taken out one by one at predetermined intervals.

Reference numeral 5 denotes a detection section, which is provided in the middle of the transport device 3 and has the following functions.

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

The second function is when two or more tickets are taken out together by the taking out device 2. In other words, if they are overlapped. Since accurate ticket detection and force loading is impossible, stacking of tickets is detected.

This detection method is, for example, an optical method that uses changes in the amount of light that passes through the ticket. Or a method of mechanically measuring and detecting the thickness of the ticket. Either one may be used.

The third function is when the tickets taken out by the taking out device 2 are abnormally close to each other. Similarly to the above, since it is impossible to accurately detect and count the tickets, their abnormal approach is detected.

This detection method is performed by detecting the spacing between tickets and comparing the spacing with a normal spacing meter.

The fourth function is. The contents of each ticket are recorded one by one. Separate invalid notes (counterfeit notes, foreign notes, expired notes, and other suspicious notes) and damaged notes.

This detection method is effective if it achieves the desired purpose. Any known optical method, mechanical method, or any other method may be used.

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

In any case. Use one set or a combination of detection devices depending on the purpose.

In this case, each detection device usually detects invalid notes (counterfeit notes, mismatched notes, stacked notes, etc., unfit notes, and notes other than genuine notes).
．． A judgment result of either a damaged note or a good note is obtained for a single note.From these judgment results, one final judgment is made for a single note according to the priority order shown below. It is given by L.

Reference numeral 6 denotes a sorting device, which sorts the tickets that have been conveyed by the conveyance device 3 and passed through the detection section 5 into a first conveyance path 7 or a second conveyance path 8 according to the determination result signal output from the detection section 5. Classified into

In other words, the detection unit 5l detects the invalid ticket. The corresponding ticket is guided to the second conveyance path 8,
The old banknotes and the corresponding banknotes are guided to the first conveyance path 7 for which the determination results of unfit and normal banknotes are issued.

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 7 is branched into a conveyance path 9 for conveying normal bills and a conveyance path 10 for conveying unfit bills. A sorting device 11 is provided at the branch point.

The conveyance path 9 is branched into a conveyance path 9b that conveys genuine bills to the first stamped ticket accumulation section 12a and a conveyance path 9b that conveys genuine bills to the second stamped bill accumulation section 12b. A sorting device 13 is provided at the point.

Also. The conveyance path 10 is divided into a conveyance path 10a that conveys unfit bills to a first unfit note accumulation section 14a and a conveyance path 10b that conveys unfit bills to a second unfit note accumulation section 14b. A sorting device 15 is provided at the branch point.

Each of the stacking units 12a, 12b, 14a, and 14b is used to stack the transported tickets in an orderly manner, and has a bottom plate that can be moved up and down.

Reference numeral 16 denotes a postmarking device as an invalidation device, which stamps a postmark on a predetermined part (for example, a numbered or marked part) of the unfitted notes conveyed through the conveyance path 10. This will invalidate the unfit note so that it cannot be used again.
? For example, a freely rotatable ink-impregnated rubber stamp roller 16
, and an idle rubber roller 162.

That is, the rollers 161 and 16 are arranged opposite to each other across the conveyance path 10, and a mark is formed on the outer peripheral surface of the roller 16 to indicate that the ticket is an invalid ticket (for example, "invalid"). .

When the unfit note is supported and conveyed on the conveyance path 10, the unfit note moves between the rollers 161 and 162. The rollers 161 and 16 rotate only during the movement and passage of the paper, and the stamp is stamped on the surface of the unfit note.

17 is a gripping and conveying device. Each accumulation part 12a, 12b14a,

Reference numeral 25 denotes a stamping device that displays necessary information such as the date, operator code, and device number on the surface of the band wrapped around the handle, as well as markings to indicate whether the bill is an old ticket or a damaged bill.

Reference numeral 26 denotes a stack sorting device which selects a stack stacking unit (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. In normal cases (when no abnormality occurs). The value obtained by subtracting the number of good and unfit notes that flowed before the sorting card from the numerical value [100] is transferred to 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 shortage 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 reading device 28 checks whether the contents recorded by the recording device 27 have been recorded correctly.

29 is the invalid ticket collection section. It is removable, and invalid tickets and sorted cards transported by the second transport path 8 are sequentially and neatly accumulated.

Reference numeral 30 denotes a take-home ticket box, which is detachable and stores the tickets taken home from each of the stacking sections 12a, 12b, 14a, and 14b when an abnormality occurs.

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 will be the reference timing for the counting comparison of every 100 sheets, which will be described later.

therefore. It is not allowed to misidentify regular tickets and classified cards.

To this end, the size of the sorting card is increased compared to ordinary tickets as they age, so that they can be detected reliably.

This detector 31. For example, an optical device consisting of a light source and a light-receiving element is used to detect a sorted card by detecting a difference in size.

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

Reference numeral 47 is a classification card issuing device, and 48 is a count verification device, the details of which will be explained below.

First, the sorting card issuing device 47 issues a banknote to be sorted (
The person who records the necessary data on the binding paper (hereinafter referred to as the obi) that binds the 100 sheets, encodes the same data as the recorded data and magnetically records it on the magnetic tape. This is the device to be created, and it is configured as follows.

That is, as shown in Figure 2. A frenulum input port 51, a conveyance device 52 that conveys the inserted frenulum, a frenulum detector 53 that detects that the frenulum has passed, and a printer that digitally records predetermined data on the frenulum being conveyed. 54, table reels 55a and 55b for supplying tapes that sandwich the frenulum on which data is recorded; ticket reel 56 for picking up the tapes that sandwich the frenulum and storing the frenulum; magnetic tape for supplying magnetic tape; Reel 57. Sorting card reel 58 that supplies strip-shaped sorting cards that hold magnetic tapes. A cutter device 59 that attaches magnetic tape to the supplied strip-shaped sorting card and cuts it into a predetermined length. Consists of 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 card, a sorted card detector 61, a sorted card transport path 62, and a sorted card ejection port 63. has been done.

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 sorted card issuing device 47 configured as described above will be explained with reference to the control circuit shown in FIG.

First, the operator removes the obi that binds the banknotes to be sorted from the note handle and inserts the obi into the slot 51.

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

When the frenulum is detected by the detector 53, the signal is applied to the transport device control circuit 72 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 is sent to the data control circuit 73 and the print control circuit 74.
is working. Data is read from a data memory (not shown) and output from the print control circuit 74 and an AND circuit 75.
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 75 (data read from the memory) and the old data supplied from the printer 54 to the check circuit 77 via the AND circuit 76, where they are compared and checked. By doing this, it is checked whether or not the data has been recorded correctly.

As a result of this check, if there is no abnormality, the signal is NOT.
is supplied to the control circuit 72 via the circuit 78 and the OR circuit 79. The conveying device 52 operates again and the frenulum on which the data has been recorded is conveyed. The ticket is sent to the ticket reel 56.

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

At this time, the data read out by the leg circuit 73 is supplied to the data conversion circuit 82 via the AND circuit 81, where it is encoded 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 are combined.
The AND circuit 83 establishes the logical product of the outputs of 2 and 7.

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.

After that. In order to check whether the data recorded on the classification 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 from the device through 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 accept 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 table reels 55a, 55b and the ticket reel 56 are driven, and the obi on which the data is recorded is stored on the ticket 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 conveyance 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) indicates that the frenulum needs to be reinserted.

In addition. A typical example of the frenulum in the classification card issuing device 47 is shown in FIG. 4, and a in the figure is recorded data.

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

In other words. A magnetic tape 92 is attached to one end of the longitudinal quotient of the sorting card 91. Each piece of data is encoded and recorded in this child loop 92.

for example. b in the figure is data corresponding to the data recorded on the frenulum. C is data indicating the presence or absence of an abnormality, d is data indicating the number of the abnormal card, and e is data indicating the number of tickets that should be in the return ticket box 30 or the invalid ticket accumulation section 29.

The width W of the card 91 is set to be, for example, about 20 mm thicker than the width of the bank note <L, and the length 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 one.
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 Figure 6. 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 counter for detecting and counting the tickets being conveyed. Device 104. Sorting device 105 for sorting cards and tickets. Card stacker 106 for collecting classified cards. A postmark device 107 that puts a postmark on a ticket, a counting device 108 similar to the counting device 104 described above, a stacking section 109 that stacks tickets, a sorting paper roll 110 that holds sorting paper for sorting tickets into 100 pieces, and this sorting paper. It is comprised of a cutter device 111 that cuts paper to the required length, and a conveyance path 112 that conveys the cut paper.

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

First, turn on the start switch (not shown). The transport device 102 operates.

next. First, a sorted card is inserted through the slot 101.

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

Thereafter, the card is transported to card stacker 106.

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

The tongue into which the tickets are inserted is counted by counting devices 104 and 108, respectively, and the tickets are 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.

Due to this. The classification of 100 tickets can be determined from the outside.

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

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 next sorted card.

Furthermore, if the above values become equal, this is displayed and the device is locked so that it cannot be operated again.

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

Of the supplied tickets, this counting circuit calculates whether the city ticket accumulation section 12a,
12b and the unfit note accumulating section 14a14b, respectively, and compare the sum of the number of good notes and unfit notes with a preset value using a certain number. This is a device that calculates the number of tickets that should be in the invalid ticket accumulation section 29, and is configured as shown in FIG.

In other words, it is assumed that the number of tickets currently supplied is the same as the set value H.
The sum of the numbers of bills that are sorted and stacked in the unfit bill stacking sections 14a and 14b is H.

The output of the detection circuit 121 connected to the ticket detector 35 is A
Total number counter 1 via ND circuits 122a and 122b
23a, 123b and the output of the detection circuit 124, which is connected to the ticket detector 36, is output from the AND circuit 125a, 125a, 123b.
The output of the detection circuit 127, which is connected to the total number counters 126a, 126b via the counter 5b and the ticket detector 37, is connected to the 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.
A so that b, 126b, and 129b operate alternately.
ND circuits 122a, 122b, 125a, 125b, 1
28a and 128b are controlled.

After the sorting card passes through the sorting device 6 and a certain period of time has elapsed, the counters 126a (126b) and 129a (129
The contents of b) are supplied to an adder 136 via a gate circuit 135 and added, and the result is supplied to a comparator 137.

Also. This comparator 137 includes a counter 123a (12
3b) is supplied via gate circuit 138. The output of the adder 136 is compared with the counter 123a (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 as follows. It is controlled by a verification control circuit 140 connected to the timing signal generation circuit 131.

Also, if the results of the above matching do not match. In the arithmetic circuit 141, the counter 123a (123
The contents of b) are subtracted, the result is supplied to the recording device 27, and the above calculation result is recorded on the classification card.

The output value of the above calculation circuit 141 should be the number of invalid tickets. If you actually calculate the number of invalid tickets and compare that value with the calculation result of the calculation circuit 141 recorded in the recording device 27, you can know the number of tickets supplied, and if the number is the set value. It can be seen how much difference there is with respect to H.

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 and 126a
, 129a, 123b, 126b, and 129b are already in use, so verification is automatically performed without stopping ticket conveyance.

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 counts signals obtained by the bill detector 36, reaches a set value, for example, 100, a signal is output from the comparator 143. Sorting device control circuit 14
4 and the sorting device, the drive circuit 145 causes the sorting device 13
is driven, and the supplied tickets are sorted and stacked in the other stacking section.

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

As a result of this comparison, if there is a match, the first genuine bill stacking section 12a is immediately driven by the stacking section control circuit 149 via the drive circuit 150a, and the bundle of 100 sheets is carried out.

Note that the comparator 146 and the control circuit 149 operate in response to a timing signal output from a timing signal generation circuit 151 that operates in response to the output of the comparator 143.

Also. At the same time as the 100 bundles are carried out, when the operation of the first regular bill stacking section 12a is completed, the regular bill stack counter 1 is started.
52 is increased by +100J.

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.
Each output of the detection circuits 154 and 155 connected to each other is counted.

Also. 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 and drive circuits 150a and 150b.

Also, the selection circuit 156 selects counts 147 and 148.
The content of is selected and retrieved, and compared with the content of the counter 142 by a comparator 157, and if they do not match, the discrepancy indicator 1 is displayed.
58 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 ticket detector 40.41 has a detection circuit 160.
, 161 are connected to each other, and these detection circuits 160, 1
Each output of 61 is counted L by the counters 162 and 163, and the sorting device 15 performs switching control for the first unfit note accumulating unit 14a and the second unfit note accumulating unit 14b in the same manner as in the case of the normal note.

In this case, the unfit bill counter 164 is incremented by r+100J at the time 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 unit selection circuit 165 and stored in the storage device 166.

However, for example, jam. If an abnormal condition such as a shift error or mismatch occurs, all normal bills and unfit bills from the unfit bill stacking section are removed. without resupply,
By adding up the number of tickets in the invalid ticket accumulation section 29 and checking the total number. Specific number of tickets supplied.
For example, check 100 sheets.

The number Q in the invalid ticket accumulation section 29 in a normal case is Q-H-G.
1 (G2) However, L, H... Setting value Gl (G2)... Total number counter 123a (123b
), whereas the total number of tickets taken out from the correct and unfit note stacking units 12a, 12b, 14a, and 14b when an abnormal condition occurs, the number of tickets in the old invalid bill stacking unit 29. The sum of is expressed as follows.

(1) When an abnormal condition occurs when only the same bundle is being supplied Q=H-G+RA+RU-PA-PU However, L, G...G1+G2 RA...Contents of storage device 166 RU...Storage Contents PA of the device 159...

Once used, this can be easily accomplished using the circuit shown in FIG.

In the figure, 171 is a memory circuit for storing abnormal conditions when they occur, 172 is an arithmetic control circuit, and 1γ3 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, QnQn+x).

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

This ticket shift path shifts the determination result output from the detection unit 5 to the sorting device 6 according to the conveyance of the corresponding ticket.
and 11, and is configured as shown in FIG.

That is, 181, 182, 183, 184 are timing signal generation circuits connected to the ticket detectors 32, 33, 34, 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.
85 and 186.

J-K type flip-flop circuit (hereinafter abbreviated as FF circuit) 185a. 185b, 185c and 186a
, 186b, 186e, and 186d, respectively.
and shift check circuits 187a, 187b, 18γC
Also supplied to 188a, 188b, 188c, and 188d as timing signals, respectively.

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 185.
It is supplied to the J and K input terminals of a.

Further, 190 is an unfit note determination circuit of the detection unit 5. 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.

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

In other words, when the tip of the ticket reaches the ticket detector 32, the tip of the ticket reaches the ticket detector 32. A timing signal T1 is output from the timing signal generation circuit 181. The FF circuit 186a of the shift register 186 is cleared by this signal, and then the data output from the invalid ticket determination circuit 189 by the timing signal T2 is set in the FF circuit 185a of the shift register 185.

Next, the check circuit 187a checks whether the above data has been set reliably using the timing signal T3.

If the result of this check is that the shifted data is different. 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 T1 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
A "0" 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 "O".
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 signal "1" when the transferred note is not an unfit note.

But it is. FF circuit 186a of 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.
Accordingly, the age of unfit notes is ``0''. “1” if it is not an unfit note
is set to Thereafter, the contents of the shift register 186 are sequentially shifted in the same manner.

After that. When the tip of the ticket reaches the ticket detector 35, the FF circuit I
When data is set in B6a, the drive circuit 194 that drives the sorting device 11 is controlled according to the content.

That is, in the old days when the content of the FF circuit 186d was "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 an accumulation section with a higher sorting priority. .

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 tickets to the invalid ticket accumulation unit 29.
For example, when a ticket passes through the ticket detector 34a while the ticket is being conveyed in the direction of conveyance. Shift mistake 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 accumulating section is driven, this bundle shift circuit holds a signal indicating whether the bundle is good or unfit, and sequentially shifts the signal and stamps the band of the bundle according to the signal by the stamping device 25. This is a circuit for stamping, controlling the bundle sorting device 26, and sorting and stacking each bundle in the stacking section, and is configured as shown in FIG. 10.

In other words. Reference numeral 201 denotes a first genuine bill accumulating unit driving circuit that drives the first genuine bill accumulating unit 12a, and 202 represents a second genuine bill accumulating unit driving circuit that drives the second genuine bill accumulating unit 12b. The outputs of circuits 201 and 202 are supplied to shift registers 204 and 205 via OR circuit 202.

The shift register 204 includes J-K type flip-flop circuits (hereinafter simply referred to as FF circuits) 204a, 20
4b, 204c, 204d, and 204e, and the input of this shift register 204, that is, the first stage FF circuit 20
The output of the OR circuit 203 is supplied to the J input terminal of 4a.

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

Reference numeral 206 indicates a first unfit note accumulating unit and drive circuit that drives the first unfit note accumulating unit 14a, and 207 indicates a second unfit note accumulating unit driving circuit that drives the second unfit note accumulating unit 14b. The outputs of the drive circuits 206 and 207 are sent via an OR circuit 208 to the first stage FF circuit 2 that constitutes the shift registers 204 and 205.
The signal is supplied to the K input terminal of the FF circuit 205a and the J input terminal of the FF circuit 205a.

In addition, each loquat 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 timing signals generated by each of the signal generation circuits 214 to 218 are supplied to shift registers 204 and 205.

Now, the drive circuit 201 drives the first genuine bill accumulating section 12a. Transfer device 17 for holding 100 genuine bills
When the bundle is conveyed to the detector 42, it is transferred from the detection circuit 209 to the timing signal generation circuit 214.
A signal is supplied to the signal generating circuit 214, and a timing signal is output from the signal generating circuit 214. The "j" signal is sent to the FF circuit 204a. A "0" signal is set in the FF circuit 205a.

This signal is. The old FF circuits 204b, 205b, and 204c, in which valid bill stacks sequentially reach the stack detectors 43 to 45, respectively.
and 205c, 205d old 205d, 204e and 205e
are sequentially shifted to 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 stamping device 25 stamps the genuine bill.
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, a "0" signal is set in the FF circuit 204a, a "j" signal is set in the FF circuit 205a, and the subsequent shift operation is performed as in the above case. The same is done.

Also, if the bundle is conveyed, the K, FF circuit 204
When “1” or “0” signals are 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 this stack does not have a signal, it is finally stamped with an unfit note indication and accumulated in the stack of unfit bills.

In this way, if the grip shift signal disappears due to noise etc. The sum will be treated as a loss-of-profit banknote.

In addition, the time it takes for a bundle to be transported between each of the grip detectors 42 to 46 is approximately constant, and if a problem such as dissipation or physical failure to transport occurs, the time required for transporting the grip between each of the grip detectors 42 to 46 is approximately constant. Loquat jam check circuits 226, 227, 2 provided in
28,229.

This checking method involves, for example, measuring the transportation time of the grip between each of the grip detectors 42 to 46. If it is shorter than the predetermined fixed time set for each. If the time is longer than a certain time, it is detected as a grip jam condition.

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

Also. The timing signal output from the timing signal generation circuit 214 is supplied to the direction change device control circuit 230. By this control circuit 230, the direction changing device 18
is controlled.

moreover. 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 this 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, the jam detection circuit used in this sorting device will be explained.

This jam detection circuit is designed to prevent damage to the device in the event that a failure occurs during the transportation of a single ticket.
This is a circuit for immediately detecting such a state, and is configured as shown in FIG.

That is, 241, 242, 243 are ticket detectors 34, 3
The output of the detection circuit 241 is supplied to the jam check circuit 244, and the output of each of the detection circuits 242, 243 is supplied to the check circuit 244 via the OR circuit 245. .

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 passing through to reaching the ticket detector 34a or 34b. If the time is longer than the predetermined time, it is determined that the ticket is jammed in the sorting device 6, a signal is output from the check circuit 244, and the jam indicator 247 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.
The check circuits 249a, 249b, and 249c are respectively supplied with the outputs of the time setting circuits 250a, 250b, and 250c.

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

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 set fixed time, it is determined that the ticket has jammed in the sorting device 11 or two or more tickets are consecutive. The check circuit 249a outputs a signal when it is determined that the ticket has been conveyed, and the check circuit 249b checks the time it takes for the ticket to pass through the ticket detector 35. The check circuit 249 determines that the ticket has become skewed or that something other than the ticket has been conveyed.
Signals are output from b, and the jam indicator 252 displays them.

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 set fixed time, the interval between tickets is too short. It is determined that the check circuit 249c outputs a signal, 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, so that the same three types of checks as described above are performed, and if a jam 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 in the lower left of the figure.

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

Every 10 of these bundles are tied together with a dog belt. this is"
called a bundle.

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

(2) Remove one loquat of 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,
Insert L into the rearmost part of the grip from which the frenum was removed in (2) above.
while storing it 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 completed and the bundles for the next magazine are prepared. Perform the same operations as from (1) above.

(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 removed ticket passes through the detection section 5, the condition of the ticket is detected. Duplicate tickets, counterfeit tickets, and different types of tickets. A determination is made as to whether the note is invalid, valid, damaged, etc.

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

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

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

(13) Good and unfit bills reach the sorting device 11. Similarly to the above, the shift signals are used to classify the bills into good and unfit bills.

(14) The tickets passing through this sorting device 11 are transferred to the force counter 12.
3a (123b).

(15) 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 are counted by the counter 142.
The sorting direction of the sorting device 13, that is, the first and second genuine bill accumulating portions 12a and 12b are switched every 00 sheets.

(16) At the entrance of the genuine bill accumulation section 12a (12b),
The number of tickets entering there is the counter 147 (148)
is counted by.

(17) The bills sorted into unfit bills by the sorting device 11 are postmarked by the postmark device 16 and are invalidated. Thereafter, they are counted by a counter in front of the sorting device 15, and the sorting direction of the sorting device 15, that is, the first and second genuine bill accumulating portions 14a and 14b are switched every 100 sheets.

(18) When the stacking unit for good or unfit bills is 100, and the stacking unit into which the bills flow is switched, the stacking unit that has accumulated 100 bills operates, and a bundle of 100 bills is carried out onto the bundle conveying device 17. , and transported to the direction changing device 18.

(19) The loquat that has reached the top of the direction change device 18 is now 9
The direction is changed by 0° and the material is 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, such as 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 shift signal from the bundle shift circuit is applied to the surface of the sealing paper to indicate whether it is a genuine bill or not. Unfit notes are clearly marked.

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

(23) On the other hand, the tickets in the supply section 1 are sorted into bundles (100 tickets) by sorting cards. When this sorted card is removed, its presence is detected by the card detector 31.

(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.

(26) 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.
It is set so that the sorting card will be located at the passage point when the counting is completed, 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 accumulating 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 then the cards are accumulated in the invalid ticket accumulation section 29.

(28) If a jam occurs in the sorting device or the stacking section, or if a shift error occurs in the sorting device 6. The jam detection circuit detects this and stops the ticket from being conveyed.

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) Also, 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) Stop taking out tickets and stack the tickets on the transport path in the stacking section. (30) After (28) and (29) above, take out all the tickets from each stacking section and put them in the take-home ticket box 30.

(31) When an abnormal condition occurs as described above, it will be displayed, so manually enter the displayed data (number) into the abnormality card, insert one sheet from the input device 4, and confirm the abnormality. After the cards are accumulated in the invalid ticket accumulation section 29, the abnormal cards are 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 on this abnormal card.

(32) After the process in (31) above is completed, supply is started again.

(33) If a recording error occurs in (27) above, stop transporting the ticket L. After L, all the tickets on the conveyance path are accumulated in a predetermined accumulation section.

After that, pull out the classified card that has been recorded incorrectly from the invalid ticket collection unit 29. Insert one card into device 4
Insert it from the beginning and record it again.

After this process is completed, 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 old invalid ticket accumulation 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 tickets and sorting cards of the bundle are extracted from the supply section 1 and conveyed from the one-sheet input device 4.

In addition. 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 accumulation 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 one by one into the slot 101 while inspecting the contents (counterfeit tickets, different types of 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, and the passmark is stamped with this device.

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

In this way, by feeding tickets separated into 100 pieces from the sealing device 21 of the main body of the device. It is sealed and stamped, and is separated by an unfit note and an L.

(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 100 sheets, and this is compared with the number of sheets read from the sorted card using calculation L.

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

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

(41) If the above-mentioned surplus or deficiency occurs, search for it from the frenulum stored in (3) above according to the number of the classification card.

Due to this. It is possible to know the condition of the frenulum, that is, the condition of the handle where excess or deficiency has occurred.

(42) Similarly, if a suspicious note is found in the above-mentioned (35) content inspection, 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 a classification card is supplied, the abnormality card of the related number is successively supplied.

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

(45) First, examine the tickets one by one in the invalid ticket collection section.
If you stop the supply when the supply is finished, the number of sheets will be insufficient, and the shortage will be 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, unfit bills being conveyed are postmarked in the middle of the unfit bill conveying path before the unfit bill accumulating section, thereby making them invalid so that they cannot be reused. By providing a postmark device, it becomes possible for the sorting device itself to automatically invalidate unfit notes.

Therefore, it is possible to eliminate the cumbersome and inefficient processing work of once accumulating unfit bill lozenges and then manually feeding them to a punching machine, which was the case in the past. Labor-saving effects can be expected.

moreover. With the configuration described above, the entire process from supplying tickets to sealing them in bundles of a predetermined number of tickets can be automated.

In addition, in the above embodiment. Although the case where banknotes are sorted has been described, the present invention is not limited to this, and can be applied to securities, slips, etc., for example. The same method can be applied to sorting other paper sheets.

others. It goes without saying that the present invention is not limited to the embodiments described above, and that various modifications can be made without departing from the gist of the present invention.

As detailed above, according to the present invention, the device can automatically process the expiry of non-reusable paper sheets and facilitate the subsequent handling of non-reusable paper sheets, etc.
It is possible to provide a paper sheet sorting device that can be expected to have various effects.
