Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a banknote counting machine having a denomination discrimination device.

Conventionally, the banknote counting machine used in the past (i.e., the banknote counting machine used in this paper) sequentially suctions each banknote in a loaded banknote bundle one by one using a spool head rotatably supported on a rotary tube. The banknote counting machine 1, which is configured to count while flipping the banknotes, does not have a built-in denomination distinguishing device for determining the denomination of the banknotes. The four banknotes were configured to simply count the number of banknotes, rjj, regardless of whether or not different types of banknotes were included.For this reason, when counting and checking the number of banknotes in a banknote stack using a banknote counting machine, Furthermore, when calculating the amount of a bundle of banknotes, there is the disadvantage that the whiteness in the bundle of banknotes, that is, the gold Wi, must be nicked by 1,000 nicks by reading the banknotes by hand.

This invention was made based on the above-mentioned circumstances, and it is possible to determine what kind of denomination the soft part of the bundle of banknotes to be counted is made of, that is, the denomination of each banknote that is turned over. By developing a denomination discriminating device that can do this, it is possible to quickly and reliably count the number of banknotes without manual reading as described above, even if, for example, one banknote of a different type is mixed in a banknote bundle. It is possible to provide a new banknote counting machine that can easily detect and check different denominations from banknotes. It is possible to provide banknote counting +!I with high added value.

With reference to the attached page 1 below, the money discriminating device #L of the present invention
An embodiment of a banknote counting machine that applies a banknote counting system having a banknote counting system to distinguish between different banknotes (this will be described in detail based on this example).

1 and 2 are a top view and a perspective view showing the schematic structure of the banknote counting operation section, in which a plurality of jt5 are concentrically arranged on the top surface f.
A banknote bundle holder 3 whose tlk support part is rotatably supported on one side of a rotary cylinder 2 which rotatably supports (5 in this example) sakushi fusuma heads 1, and an inner surface of this holder 3. An arm member 5 is provided with a banknote bundle holding rod 4 horizontally disposed on its free end close to the center of the side channel. In addition, an arcuate banknote stopper 6 is vertically disposed at the front of the holder 3 adjacent to the free end thereof. On the other hand, a non-contact switch 7 is installed close to the side wall surface of the rotary cylinder 2, and the same number of switches as the sash 1, that is, 5 in this example, are installed on the side peripheral wall surface of the rotary cylinder 2. A piece of magnetic material 8, such as a piece of iron, is attached.

Next, to explain the operation of the banknote counting machine configured as described above, first, in a steady state in which no banknote counting operation is performed, the banknote bundle holder 3 is placed at the position farthest from the rotary cylinder 2 @1.
They are each stably held at the positions indicated by solid imaginary lines in the figure.

When performing the counting operation, first, the banknote bundle 9 to be counted is placed slightly on the holder 3 in a predetermined state, and when the holder 3 is rotated clockwise by a predetermined angle, the banknote bundle 9 is held by the presser. It is held between the rods 4 and set at the position closest to the rotary cylinder 2 as shown by solid lines in Figures 1 and 2.

Next, in this deaf state, the rotary cylinder 2 is rotated in a predetermined direction (counterclockwise in this example) at a predetermined speed. At the same time, in synchronization with the rotation of the rotary cylinder 2, each sling head 1j) moves the 11411 surface part φ of the banknote bundle 9 located above the presser rod 4 at its closest position. central i
The suction port 10 with the suction port 10 is placed opposite to the paper banknote stack 9 and sucks the innermost bill from the banknote stack 9, and then releases the suction force to record the turned-over banknote. The banknote bundle holder 3 and the presser rod 4 are rotated at a predetermined speed in the direction opposite to the rotary cylinder 2, that is, clockwise in this example.
Each banknote in the banknote bundle 9, which is held in a predetermined state between
After being peeled off by the connecting head 1, it is conveyed to the rear. Therefore, it is common knowledge for those skilled in the art that the number of banknotes in the banknote bundle 9 can be easily counted by providing a device so that this one counting pulse is generated every time the non-contact switch 7 is closed. As is well known, the banknotes currently in use in Japan are of four types: -10,000 yen, 5,000 yen, 1,000 yen, and 500 yen. As shown in Figures 3 and 4, the height of the banknotes of the same type decreases in this order.Also, as mentioned above, the banknote bundle 9 to be counted is placed on the banknote bundle holder 3 of the banknote counting machine. When carrying out banknotes, only banknotes of the same title are usually loaded with their carpeting surfaces and bottoms lined up.

According to the present invention, in the banknote counting machine having the above-mentioned configuration, as the rotary tube 2 rotates, the banknote bundle holder 3 is loaded in a predetermined state, and the relationship ε between the holder 3 and the presser rod 4 is maintained. While the banknotes in the bundle of banknotes 9 are being conveyed so that they are turned over one by one by the action of each suction head l on the rotary tube 2, for example, the first
As shown in the figure and the second factor, the projection light 14 from the projector 13 illuminates the upper end of each banknote through the projection lens 12 by the synchronization signal with the instantaneous rotary cylinder 2 sucked into the suction head 1.
The transmitted light 15 obtained by irradiation from one lens is transmitted through a condensing lens 16
A plurality of (four in this example) 21 photoelectric conversion elements are provided inside the light receiver 21 through the heat exchanger.

21B, 210.21Dl Therefore, as shown in Figure 1g3, a guard device is installed to receive the light.

The oblique parts 17A, 17B, 17C, and 17D in FIG. 3 is an illustration of each transmitted light monitoring area.

FIG. 5 shows a stack of banknotes 9 which are clamped and loaded in the rotary flea banknote bundle holder 3 with the rotation WI2 as described above, one by one by each suction head 1. The upper end of each banknote that is being turned over is irradiated with the projection light 14 from the projector 13, and the transmitted light 15 is detected by the denomination (this light is received by the photoelectric conversion elements 21A to 21Di in the light receiver 21). This is configured to determine whether or not different types of banknotes are mixed into the banknote bundle 9 by using the output signal from each of the photoelectric conversion elements 21A to 211J. Hammer discriminating device 1 according to Octopus's invention ζ
FIG. 3 is a schematic circuit diagram of a different ticket discriminating device including the T.

That is, the upper optical zone conversion elements 21A, 21B, and 2IC.

A peak point holding circuit 23A consisting of an R-8 flip-flop circuit is applied to each of the outputs of the output terminals 21D and 21D, which are appropriately widened by one width through corresponding amplifiers 22A, 22B, 22C, and 22D. , 23B.

23C and 23Dl are applied and stored. The stored signals of the stiff peak point holding circuits 23A to 23D are stored in comparison circuits 24A and 24, respectively, each consisting of a threshold circuit, for example.
The voltages applied to B, 24C, and 24D are compared with predetermined V and 0 constant levels for each mold. Scary comparison circuit 24
Output signals representing the comparison results from person 24D are applied to the ticket type discrimination circuit 25.

On the other hand, as the rotary cylinder 2 rotates, each time a banknote in the banknote bundle 9 loaded on the banknote bundle holder 3 is turned over by the action of the suction head 1, the above-mentioned counting pulse is generated. The counting pulse (fifth pulse) as shown in FIG.
In the circuit shown in the figure, this pulse is used as a synchronizing pulse signal) as an input signal, as shown in Fig. 6(d), (6).
For example, four cascaded Ds generate four-way timing pulse signals as shown in (f) and (g).
A timing signal generation circuit 27 consisting of a type flip-flop circuit is provided. Therefore, this timing signal generation circuit 2
7 to 61J(d)) At the time when the first timing pulse t as shown in FIG.

That is, as is clear with reference to FIGS. 3 and 4, the banknote bundle 9 loaded in the gold banknote east holder 3iC is turned over by the swiping head 1 and irradiated with the projection light 14 from the projector 13. If the banknote is a 10,000 yen note, the photoelectric conversion element 21A provided in the light receiver 21 corresponding to the 10,000 yen note receives the largest amount of light input, and the intensifier 22k is through the peak point holding circuit 23
A is definitely set to the operating state U (set state).At this time, some light receiving input is also received by the photoelectric conversion elements 21B to 21D corresponding to the remaining 5,000 yen notes, 1,000 yen notes, and 500 yen notes. However, in the case of the usual 10,000 yen note, the peak point holding circuit 23
B to 23D are cases of a 10,000 yen note that has been partially worn out without being set to the operating state (this is the only case that is designed so that it can be set to the operating state).

As a result, if the 10,000 yen note is illuminated by the projection light 14 from the projector 13, the ticket type discrimination circuit 25 detects the 10,000 yen note, 5,000 yen note, 1,000 yen note, and 500 yen note number. From the corresponding output terminals A, B, C and D, when the timing pulse t is generated from the timing signal generation circuit 27, '1', X,
The apparatus is arranged to derive a series of logical output signals representative of the bill type discriminating circuit: X, X' (where X represents either O or 1).

On the other hand, when 5,000 yen is illuminated by the projected light 14 from the projected light 1 $ 13, as is clear from FIG. There is virtually no light receiving input, and the most multiple light receiving input is received by the photoelectric conversion element 21B corresponding to the 5,000 yen note.For this reason, only the peak point holding circuit 23B is reliably in operation via the amplifier 22B. The set r1 peak point holding circuit 23A is held in an inoperative state (reset state).At this time, the photoelectric conversion elements 21C corresponding to the remaining 1,000 yen notes and 500 yen notes
, 21Di can also obtain some light receiving input, but in the case of a steady 5,000 yen note (as in the case of a 10,000 yen note), the peak point holding circuits 23C and 23D are not set to the operating state. It can be set to the operating state only in the case of a 5,000 yen note that has been significantly worn down by about 1 part.

As a result, if the 5,000 yen note is irradiated with the projected light 14 (V) from the projector 13, the timing 1g generation circuit 2
From 7 onwards, the timing pulses t and t are generated, respectively, at the binary logic levels o, i, x, and x' as shown in the table above.
A series of wi output signals representing the species discrimination results are derived.

Furthermore, when a 1,000 yen note is illuminated by the projection light 14 from the projector 13, as is clear from the ma-yu, -
Photoelectric transformer compatible with 10,000 yen and 5,000 yen notes! element 21A,
There is virtually no light receiving input to the photoelectric transformer 21B, and a large amount of light receiving input is obtained to the corresponding photoelectric transformer 21C.

Therefore, the peak point holding circuit 23C is connected via the amplifier 22C.
Only certain operation conditions are set: 23 peak point holding circuits are set.

23B is set and maintained in an inactive state. At this time, the photoelectric conversion element 21D corresponds to the remaining 56-yen note.

(The light receiving input is slightly different here, but in the case of a regular 1,000 yen note, the peak check cycle M23D is not set to the operating state and is partially The operating condition g+ can be set only in the case of a 1,000 yen note that has a large amount of wear.
If it is illuminated by
When the timing pulse t is generated from the timing signal generation circuit 27 from each output terminal A-1) of the output terminal A-1), the binary logic levels 'o and o as shown in the upper part, respectively, are output.

A logical output signal sequence of the ticket type discrimination result of 1, X'' is derived.

Photoelectric conversion element 21A compatible with 5,000 yen notes and 1,000 yen notes
21C1 moss has virtually no light receiving input. Therefore, only the peak point holding circuit 230 is in the operating state (this setting is made via the amplifier 22D).The remaining peak point holding circuits 23A to 23C
The 91 setting is maintained in the inactive state. As a result, if the 500 yen note is irradiated by the projection light 14 from the projector 13 (the above output terminals A of the note type discrimination circuit 25,
From D, at the timing (when the timing pulse t1 is generated from the 1! number generation circuit 27), the 2 pulses as shown in the table above are generated.
A series of logical output signals representing the result of the ticket type discrimination of value cooking level 'o, o, o, i' is derived.

On the other hand, the banknotes irradiated by the projection light 14 from the container 13 are projected onto the sax 1 head 1 regardless of the type of banknote.
If two or more tickets are turned over at the same time due to a malfunction, if the ticket is damaged, or if there is an abnormality such as a noticeably soiled ticket, the light-receiving spear of each party/electronic conversion element 21λ~211) may be damaged, or if the light-receiving spear of each party/electrical conversion element 21λ~211) is a regular ticket as described above. The peak point holding circuits 23A to 23D are not set to the operating state but are kept in the inactive state g (this setting is not held). As a result, in such a case (in this case, each output terminal λ to D of the bill type discriminating circuit 25 outputs the output terminals λ to D as shown in the above table at the time when the timing pulse 1° is generated from the timing signal generating circuit 27). 2 (1M+ logic level o, o, o, o', a series of logical output signals representing abnormal bill type discrimination results are derived. f (In this case (

A series of fermentation output signals as shown in the table above are derived from each output terminal 1000 to D of the discrimination circuit v825 according to the card number. Furthermore, in this embodiment, in order to distinguish between different kinds of bills, the series of logic output signals mentioned above is used in the different woodchill bill discrimination circuit 30;
At the same time, a second timing as shown in FIG. When the pulse t is generated, the memory II'll path 31
After the timing pulse generating circuit 27 generates the third timing pulse t as shown in FIG. 6(a).
i The period of occurrence of the trough of the counting pulse ′r<h as shown above
Suction head l (equal to 1 m4 of turning movement for one banknote) (has a slow polishing time equal to this) is transmitted from the timing signal generation circuit 27 via the 1″6 delay circuit 32 as shown in FIG. 6(h). A timing signal t delayed by one period such as
, is applied, a new ticket type discrimination signal string as described above is directly applied in sequence from each output terminal 100 to D of the ticket type discrimination circuit 25 and other output terminals of the ticket type discrimination circuit 25. A'~D
' is applied through the memory circuit 31 and is successively compared with the banknote type determination signal sequence n cycles before, and only when a match is not obtained, a mismatch output is applied to the terminal 34 via the signal 1133. By lighting a lamp or driving another appropriate notification device lt, it is possible to notify that a different type of banknote has been mixed in the banknote bundle 9 being counted.

As mentioned above, when the banknote bundle holder 3 is fully loaded and the rotary cylinder 2 is rotated, the banknote bundle holder 3 is loaded and the rotary cylinder 2 is rotated.
From this point on, each bill is sequentially turned over one by one and counted, and the timing signal generation circuit 2 performs a flea check every time when all the different banknote discrimination operations necessary for each banknote in the banknote bundle 9 are completed.
The 41st timing pulse t4 as shown in FIG. 6(g), which is generated from the timing pulse t4 shown in FIG.

FIG. 6(b) shows the official denomination loaded in the banknote bundle holder 31 in the photoelectric conversion elements 21A to 21D (the output denomination to be derived from the corresponding photoelectric conversion element). In the case of a normal denomination and a regular banknote, it is sufficient to set the peak point holding circuit corresponding to the counting pulse shown in FIG. However, in the event of a 94-bit error or an abnormal state as described above (as shown by the broken line), the level is so low that it is impossible to set the corresponding peak point holding circuit to one operating state.

The ticket type discrimination circuit 25 for performing the above-mentioned operation is as follows:
For example, each of the terminals A, D, and λ' to D' has an input terminal to which the above-mentioned timing pulse signal R is applied and an input terminal to which each corresponding comparator output of the comparator circuits 24A to 24D is applied; Each corresponding terminal (four two-person AND circuits each having an output terminal connected to
Each output terminal of the circuit (61 four terminals each having an input terminal connected to this and one output connected to the traffic signal 281)
This can be realized by using a human-powered NO processing circuit. Also, the different ticket discriminating circuit 30 has an input connected to the output terminal of the delay circuit @32, and one corresponding output terminal among the terminals A and D, respectively. four three-person AND circuits having terminals, and one four-person NOR having an input terminal connected to each output terminal of the hard AND circuit and having an output terminal connected to the above signal. It will be readily understood by those skilled in the art that it can be implemented using circuits.

As is clear from the detailed description above, the banknote counting machine having the denomination discrimination device according to the present invention counts the number of banknotes in the banknote bundle 9 loaded onto the banknote holder 3. Since the denomination of each banknote in the paper bundle 9 can be determined, for example, when discriminating between different types of banknotes, the standard banknote can be memorized and the denomination can be easily compared with this standard banknote. Since it is possible to detect and check the contents of the banknote bundle, it is no longer necessary to check the contents of the banknote bundle by hand, as was the case in the past.
For example, if it is difficult to detect that a banknote of a different denomination has been mixed in, all that is required is to perform a manual check, which has the advantage of significantly improving the banknote counting ability due to the banknote counting operation.

Figure 7 shows the different ticket identification device 3 configured as shown in Figure @5.
The alarm is generated as described above by using the abnormality signal t7 generated from the terminals 29 and 34 of 5, and the ml
! This is a schematic block diagram of an additional device t section configured to temporarily stop banknote counting operation.

That is, the paper counting machine generally has an endless belt 44 wrapped between the rotary tube 2 and a V-shaped pulley 43 attached to the rotation @ 42 of the counting motor 41. It is driven to rotate at a predetermined speed in a predetermined direction as shown by the arrow in the figure, and at the same time, each of the above-mentioned slicing heads 1, which are provided on the rotary cylinder 2, are rotated at a predetermined speed in the opposite direction to the rotary cylinder 2 as shown by the arrow in the figure. Under the control of the pressure switch 45, each banknote in the banknote bundle 9 loaded on the banknote bundle holder 3 is sequentially turned over by suction force starting from the innermost banknote and then conveyed further backward.

The input gate of the counting pulse generating circuit 26 connected to the banknote counting path CAi is driven intermittently in synchronization with the above-described operation of turning over each banknote by each succinct head 1. The circuit 46 is controlled to be a closed circuit in accordance with the operation of the pressure switch 45 and the non-contact switch 7.
The output 1 of A is connected to the banknote number display circuit 47.

In this FIG. 7, the terminal 2 of the dissimilar ticket discriminating device f35
9. If an abnormal signal or a different type of ticket signal as described above is generated by connecting to an appropriate alarm circuit 49 such as a lamp or buzzer through the 34i0R circuit 48 and also connecting to the input gate circuit 46j. When a flea generates an alarm, it locks the input gate circuit 46 in an open circuit state, causing the counting pulse generation circuit 26 to perform the counting pulse generation operation, and therefore the counting circuit CA to perform the counting operation and display circuit 4.
An example is shown in which the display contents in step 7 are temporarily stopped. In this case, the bill turning and collecting operation by each swipe head 11 may be continued to the end regardless of whether or not the above-mentioned abnormal signal and irregular bill signal are generated.

With this configuration, it is possible to clearly identify the presence of different m-bills in the banknote bundle that has been counted. ◆Different types of tickets can be detected more easily than this.

(Thus, you can more reliably and quickly press different types of bills in a banknote bundle,
There are advantages that can be obtained.

Recommendation: (This is an example of a banknote configuration with Φ.) If this configuration is used, the dissimilar bill discriminating circuit 30 (therefore, a dissimilar bill is mixed into the banknote bundle in the itt number) In addition, it is possible to find out whether or not it is in the 5000 yen group (in this case, if a foreign force pays 1 dollar, the type of the foreign ticket is 10,000 yen, 5,000 yen group, 1,000 yen group, 500 yen group) There is an advantage that it is possible to detect which of them is t7.

When a matching output is detected from the comparison circuit 73, the opening/closing control circuit (not shown) of the banknote bundle holder 3 is turned on via the signal line 74, and when a mismatching output is detected, the signal line A suitable WI information circuit 76 such as a lamp is driven through the WI signal line 75 to generate the i# information, and at this time, the opening/closing control circuit of the banknote bundle holder 3 is not driven to keep the holder 3 closed. The configuration is such that the state pt is maintained. In this case, the oven l of the holder 3 can be controlled by a normal reset signal.

FIG. 11 shows a state in which the gold coins are loaded in a predetermined state on the holder 3, and are turned over one by one starting from the one on the inner side by the action of the succinct head 1. If the lower part of each banknote in the banknote bundle 9, whose upper end is illuminated by the projection light 14 from the projector 13, is further illuminated by another projector, the lower ends of the banknotes will be illuminated. An example of a circuit configured to improve the damage axis rt of the above-mentioned abnormal effort signal and abnormal signal using reflected light will be shown.

In other words, as shown in FIG. There is no problem if the bottoms of the banknotes in the bundle 9 are properly aligned, but if they are not aligned to a certain extent, the reliability of the banknotes will be lowered.

Therefore, in FIG. 11 of FIG.

With this structure, if the banknote bundle 9 loaded on the banknote bundle holder 3 does not contain any items with uneven bottom surfaces, that is, the placement surfaces (in this case, the photoelectric conversion element 21K It is clear that since reflected light is always received in this case, the operation for discriminating different types of bills can be performed at a completely different time than in the case of FIG.

On the other hand, if the banknote bundle 9 contains banknotes with uneven bottom surfaces, the fifth factor completely ignores such a phenomenon, so that the reliability of the dissimilar banknote discrimination operation is poor and stiff. In Figure @11, when the banknote bundle 9 contains banknotes with uneven placement bottom surfaces, the amount of light received by the photoelectric conversion element 21 decreases considerably at this banknote part, and the total AND circuit 81 to 81D fails. state, and as a result, the photoelectric conversion elements 21A~
An abnormality signal is unconditionally generated at the terminal 29 via the signal a28, regardless of the light receiving state of the sensor 21D.

As a result, the circuit shown in FIG. 11 has the advantage of being able to perform a different type of bill discrimination operation with higher reliability than the circuit shown in FIG. 5.

Note that this invention is not limited to only those with the above-mentioned configuration, but substantially all those having the same technical idea)
Needless to say, it is applied with great care.

In the banknote counting machine 1, the suction head (a plurality of photoelectric droplets each having a different monitoring area) each receives light obtained by irradiating light from a light source to the upper four parts of the banknote that is being turned over. Riko, a photoelectric conversion element for confirming the lower edge of the bill that receives light obtained by irradiating light from a light source to the lower shoulder of the banknote that is being turned over through the suction, and each of these photoelectric conversion elements. (Based on this, there is a bill type discriminating circuit that discriminates the hammer from the height of the blind bill, and a timing pulse is output to the bill type discriminating circuit in synchronization with the rotation of the rotary cylinder to activate the circuit. 1. A banknote counting machine having a denomination discriminating device, characterized in that a timing signal generating circuit for operating the banknote discriminating device is provided.
