Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cancellation processing method in a banknote processing device built into a vending machine or the like.

Some vending machines, such as those for railway tickets, are equipped with a coin handling device that identifies and counts inserted coins, as well as a bill handling device that inspects, counts, and stores inserted banknotes. be.

This banknote processing device includes a banknote insertion slot, a bill checker (banknote verification mechanism) that determines the authenticity of inserted banknotes, a mechanism that temporarily holds banknotes determined to be genuine by this bill checker, and a banknote A banknote storage box for storing banknotes, a banknote return slot, and necessary transport paths are provided.

The bills inserted into the bill insertion slot are first judged to be genuine or false by a bill checker, and only the bills determined to be genuine are sent to the temporary holding mechanism through the conveyance path and are temporarily held.

Even when two or more banknotes are inserted, the plurality of banknotes are temporarily held in a stacked state.

By the way, automatic vending machines are usually provided with a push button/switch for cancellation, and when this push button/switch is pressed, the already inserted banknotes are returned to the banknote return slot.

However, in the conventional cancellation processing method, the first banknote is temporarily held in a temporary holding mechanism, and the second and subsequent banknotes are stacked on top of each other and temporarily held. After completing the process, the banknotes are sent out to the banknote return slot through a return path, which inconveniences the processing time required to return the banknotes and therefore the waiting time of the customer.

This invention was made in view of the above-mentioned circumstances, and it is possible to shorten the processing time for returning banknotes when a cancellation input is made in the banknote processing device, and to simplify the control of the return processing. This provides a cancellation processing method that can be used.

Embodiments of the present invention will be described in detail below with reference to the drawings.

FIG. 1 shows a banknote processing device.

This banknote handling device is built into a banknote handling device such as an automatic ticket vending machine for railway tickets, an automatic currency exchange machine, and an automatic cash deposit machine.

The banknote handling device is provided with cancellation pushbutton switches (FIGS. 2 and 3, 14) for canceling an invoice or transaction operation at required locations.

In FIG. 1, the banknote processing apparatus includes a banknote insertion slot 11, a banknote return slot 12, a bill checker 13 that determines the authenticity of a banknote (for example, a thousand yen banknote) inserted into the banknote insertion slot 11,
A banknote temporary holding mechanism 2 that takes in and counts the banknotes determined to be true by this bill checker 13, and holds the taken banknotes until a cancellation signal is input or the next customer inserts a banknote.
0, a banknote storage mechanism 30 that has a banknote storage box 31 and arranges the banknotes after temporary storage and stores them in the banknote storage box 31, from the bill checker 13 to the temporary storage mechanism 20, and from the time storage mechanism 20 to the banknote storage mechanism 30, and the temporary hold mechanism 20
It is provided with a banknote transport mechanism that sends banknotes from the banknotes to the banknote return port 12, and a drive device for each mechanism including this banknote transport mechanism.

The bill checker 13 includes a banknote conveyance mechanism and a banknote determination device that determines the authenticity of banknotes.

This conveyance mechanism is capable of switching the conveyance direction, and normally conveys the banknote inserted from the insertion slot 11 in the direction of the carry-in path 41, and if the inserted banknote is a fake, a reversal signal, which will be described later, is sent. In this case, the banknotes are conveyed in the direction of the insertion slot 11.

The banknote determination device completes the authenticity determination of the banknote and outputs a determination completion signal when the banknote is a genuine banknote.

The bills inserted into the bill insertion slot 11 are first judged to be genuine or false by a bill checker 13, and the bills determined to be genuine are passed through an inlet path 41 consisting of a large number of pulleys and a conveyor belt hooked around them. It is sent to the temporary holding mechanism 20.

If the bill checker 13 determines that the bill is false, the bill checker 13
The conveyance mechanism inside the checker 13 is reversed and the banknotes are inserted into the insertion slot 11.
will be returned to.

Further, as will be described later, even if a cancellation signal is input before a determination completion signal is output, the conveyance mechanism is reversed and the banknote is returned to the insertion slot 11.

A banknote passage detector 25 made of a photoelectric detector is arranged in the middle of the carry-in path 41.

Based on the bill detection signal from the detector 25, the number of bills is counted.

The banknote temporary holding mechanism 20 includes a temporary holding drum 21 and a presser belt 22 wrapped around the drum 21, and holds the banknotes sent through the conveyor belt 41 on the drum 21.
It is held between the outer peripheral surface and the pressing belt 22.

A held banknote detector 26 made of a photoelectric detector is arranged near the banknote discharge side of the holding mechanism 20.

This detector 26 detects banknotes wound around the drum 21.

The drum 21 is driven by a drive motor 51, which will be described later, and its clutch and brake (both shown) are controlled based on detection signals from detectors 25 and 26.

That is, the drum 21 is rotated when the detector 25 detects the leading edge of the banknote being conveyed through the carry-in path 41, and the drum 21 is rotated when the detector 26 detects the leading edge of the banknote wrapped around the drum 21. will be stopped.

As a result, the banknotes conveyed sequentially by -1 are retained on the drum 21 in an overlapping state.

The banknote storage mechanism 30 includes a banknote storage box 31, a conveyance path 42 for conveying banknotes from the temporary holding mechanism 20, which is made up of a pulley and a belt hung on the pulley, a lever 32 for detecting the completion of conveyance provided on the conveyance path 42, It includes a stopper 33 provided near the end of the conveyance path 42 and a pusher 34 for pushing banknotes.

A vertically elongated bill storage opening 35 is opened at a portion of the bill storage box 31 facing the conveyance path 42 .

The detection lever 32 is pivotably mounted at approximately the center point, and one end thereof looks into the conveyance path 42, and a photoelectric detector 27 is provided near the other end to detect the swinging of this other end. .

The bushing 34 is driven by a solenoid (as shown).

Further, a switching flapper 44 is swingably provided between the banknote discharge side of the temporary holding mechanism 20 and the carry-in side of the conveyance path 42.

This switching flapper 44 is switched by a solenoid 52 via a link mechanism (as shown), and is normally in a position that prohibits the transfer of banknotes to the conveyance path 42 as shown by a solid line, and when the solenoid 52 is energized, a chain line 44A The banknotes are moved to a position where the banknotes are guided to the conveyance path 42 as shown in .

The pulley of the conveyance path 42 is connected to a drive motor 51 via a clutch.
The clutch is driven by Bill Checker 13
It is controlled based on detection signals from a bill insertion detector 29 and a detector 27 provided near the entrance of the bank.

When it is detected that the first bill of the next customer has been inserted based on the detection signal from the bill insertion detector 29,
The pulley of the conveyance path 42 and the temporary holding drum 21 are rotationally driven, and the switching flapper 44 is switched to the position indicated by 44A.

As a result, the banknotes held on the drum 21 leave the drum 21 and move to the conveyance path 42.
It is transported by.

While the banknote is being conveyed through the conveyance path 42, the banknote comes into contact with the one end of the detection lever 32, so the other end rises slightly and blocks the light projected by the detector 27, causing the detection output from the detector 27 to be transmitted. Occur.

When the banknote passes the position of the detection lever 32, the detection lever 32 returns to its original position and the output of the detector 27 falls.

The switching flapper 4 is switched by the fall of the output of the detector 27.
4 returns to its original position, the movement of the conveyance path 42 is stopped, and the bushing 34 begins to move toward the storage box 31.

The banknotes stop when they hit the stopper 33, but in the case of a plurality of banknotes, they are aligned during the conveyance process and when the banknotes are stopped.

The stopped and aligned banknotes are pushed by the pusher 34 and put into the storage box 31 from the storage port 35.The first banknote of the next customer inserted into the insertion port 11 is
The drum 2 passes through the building checker 13 and the loading path 41.
Needless to say, it will be sent to No. 1 and temporarily held there.

By the time this first bill reaches the position of the switching flapper 44, the bill storage operation has been completed, and the flapper 44 has returned to its original position.

The banknote transport mechanism includes a banknote return path 43 in addition to a carry-in path 41 and a transport path 42 .

This banknote return path 43 is also composed of a large number of pulleys and a belt hung around these pulleys.

A switching flapper 45 is swingably provided between the carry-out side of the temporary storage mechanism 20 and the carry-in side of the return path 43.

This switching flapper 45 is also switched by the solenoid 53 via a link mechanism, and is normally in a position where transfer of banknotes to the return path 43 is prohibited, as shown by the solid line, and when the solenoid 53 is energized, it is in a position as shown by the chain line 45A. It reaches a position where the banknotes are guided to the return path 43.

Further, in the vicinity of the return port 12 of the return path 43, a returned bill detector 2B, which is a photoelectric detector, is arranged to detect returned bills.

As will be described later, when the cancellation signal is input after the determination completion signal is output from the bill checker 13, and when the cancellation signal is input after the number of inserted banknotes becomes two or more. As the drum 21 rotates, the switching flapper 45 is switched to the position 45A, so the banknotes temporarily held on the drum 21 are transferred to the drum 2.
1 and move to the return route 43.

Further, the banknotes on the carry-in path 41 are temporarily held in the drum 21 and then moved to the return path 43, and are conveyed through the return path 43 and discharged from the return port 12.

When the tip of the banknote to be returned is detected by the detector 28, the rotation of the drum 21 is stopped based on this detection signal, and the switching flapper 45 returns to its original position.

The drive device of the banknote conveyance mechanism includes a power transmission mechanism of the drive motor 51, clutches for the pulleys of the temporary holding drum 21 and the conveyance path 42, switching solenoids 52 and 53 of the switching flappers 44 and 45, and a solenoid of the pusher 34. I'm here.

The rotational force of the drive motor 51 is transmitted to the pulleys of the carry-in path 41, the conveyance path 42, and the return path 43.

This drive motor 51 starts when the first bill is inserted, and when the bill handling device reaches a predetermined stage of sales or transaction processing after inserting the bill, for example, in the case of an automatic ticket vending machine. When the account selection pushbutton switch for selecting the desired fare provided on the customer service panel is pressed, or when the detector 28 of the return path 43 detects the end of the bill, the return of the bill from the return slot 12 is completed. When to stop.

FIG. 2 mainly shows the cancellation processing control portion of the control device of the banknote processing apparatus in the case where only one banknote is handled.

A microprocessor (hereinafter referred to as CPU) 60 controls the entire operation of the banknote processing apparatus.

The CPU 60 receives signals from each of the detectors 25 to 29, the cancellation push button/switch 14, etc.
Based on these input signals, the U60 outputs signals for controlling the drive device, that is, the drive motor 51, the switching solenoids 52 and 53, the clutch and brake of the drum 21, etc., and performs the above-mentioned temporary holding and storage of banknotes. It will be done.

The cancellation control circuit consists of three flip-flops 61, 6.
Contains 2,63.

The flip-flop 61 temporarily stores the determination completion signal, and the determination completion signal from the building checker 13 is input to its set input terminal.

The flip-flops 62 and 63 each output a return command signal, and the set output of the flip-flop 62 is sent as a return signal to the drive device of the temporary holding mechanism 20, and the set output of the flip-flop 63 is a building signal. - Sent to the bill checker 13 as a reversal signal for the transport mechanism within the checker 13.

These flip-flops 61 to 63 are all CP
It is reset by a reset signal from U60.

This reset signal is activated when the banknote return operation is completed.
That is, when the detector 28 outputs the end detection signal of the banknote returned through the return path 43, when the banknote insertion detector 29 in the bill checker 13 detects the end of the banknote to be returned, and when the banknote handling device When a sale or transaction process reaches a predetermined stage, for example when an account selection pushbutton switch is pressed in the case of an automatic ticket vending machine, the CPU
It is output from 60.

The set output of the flip-flop 61 is an AND circuit 64
The reset outputs are respectively input to an AND circuit 65.

Also, the cancellation signal from the CPU 60 is output to the AND circuit 64.6.
Enter 5.

This cancellation signal is output from the CPU 60 when the pushbutton switch 14 is pressed.

The outputs of AND circuits 64 and 65 are sent to set input terminals of flip-flops 62 and 63, respectively.

Now, the flip-flops 61-63 have already been reset by the previous bill return process or by the bill handling device's sale or transaction process.

When the judgment completion signal is output from the building checker 13, the flip-flop 61 is set, so the AND circuit 6
Gate 4 opens.

When the cancellation push button switch 14 is pressed in this state, a cancellation signal is output from the CPU 60, and this cancellation signal is sent to the flip-flop 62 via the AND circuit 64, so the flip-flop 62 is set. A return signal is sent to the temporary hold mechanism 20.

As a result, as described above, the drum 21 rotates and the switching flapper 45 is switched to the position 45A, so that the banknotes temporarily reserved in the drum 21 are sent to the return path 43 and returned from the return port 12.

Further, the banknotes in the carry-in path 41 are once wrapped around the drum 21 and then transferred to the return path 43 and returned from the return port 12.

Before the judgment completion signal is output, the flip
Since the flop 61 remains reset, the gate of the AND circuit 65 is open.

At this time, if a cancellation signal is output, this cancellation signal is AND
Since the flip-flop 63 is set via the circuit 65, a reversal signal is sent from the flip-flop 63 to the bill checker 13.

As a result, the conveyance mechanism of the bill checker 13 is reversed.

The fact that the determination completion signal has not yet been output means that the banknote is in the bill checker 13 and the authenticity of the banknote is being determined.

If a cancellation request is made during the authenticity determination, the banknotes in the bill checker 13 are returned to the insertion slot 11.

Needless to say, at this time, the authenticity determination process by the bill checker 13 is canceled.

FIG. 3 shows a case where one or more banknotes are inserted in one sale or transaction process.

In this circuit, at least one banknote is transferred to the drum 21.
A flip-flop 66 is provided to detect that the signal is temporarily held.

This flip-flop 66 is set by a detection signal from the stored banknote detector 26 provided near the banknote ejection side of the storage mechanism 20, and is set when the return operation is completed and when the sale or transaction processing of the banknote handling device is completed. It is reset when a step is reached, such as when an account selection pushbutton switch is pressed in the case of an automatic ticket vending machine.

Set output of flip-flop 66 and CPU 60
A cancellation signal from is sent to the AND circuit 67.

The outputs of both AND circuits 64 and 67 are sent to the set input terminal of flip-flop 62 via OR circuit 68.

The flip-flop 61 is reset each time a banknote is inserted based on the output of the banknote insertion detector 29 in addition to when the banknote return operation is completed.

The other configurations are the same as those shown in FIG.

If the first bill is in the bill checker 13 and the cancellation signal is output before the determination completion signal is output, the flip-flop 63 is set and the reverse signal is set to the bill checker 13.
Since the bills are sent to the checker 13, the bills in the bill checker 13 are returned from the insertion slot 11.

When the authenticity determination of the first banknote is completed, the flip-flop 61 is set, so if a cancellation signal is output after this, the flip-flop 62 is set and a return signal is sent to the temporary holding mechanism 20. Therefore, the banknotes are returned from the return slot 12.

When the first bill is sent out from the bill checker 13 and sent to the temporary holding mechanism 20 through the carry-in path 41, a detection signal is generated from the detector 26, and the flip-flop 66 is set by this signal. be done.

After that, when the second banknote is inserted into the bill checker 13, the flip-flop 6 is activated by the output of the detector 29.
1 is reset.

During the authenticity determination of this second bill, a cancellation signal is sent to the CPU 6.
If the output is from 0, the flip-flop 62 is set because the flip-flop 66 has already been set, and the flip-flop 63 is also set because the flip-flop 61 has been reset, so the return signal is and the reversal signal is connected to each flip-flop 62.6
Output from 3.

As a result, the first banknote held in the temporary holding mechanism 20 is returned through the return slot 12, and the second banknote in the bill checker 13 is returned through the insertion slot 11.

After the authenticity determination of the second banknote is completed, the flip-flop 61 is set, so only the return signal is output, and both the first and second banknotes are returned from the return slot 12.

The same applies to the third and subsequent banknotes.

FIG. 4 shows a case where the CPU 60 executes processing equivalent to the processing by the return processing circuit shown in FIG.

First, it is determined whether the cancel pushbutton switch 14 has been pressed (step 1), and if it has been pressed, step 2
Proceed to , and if it is not pressed, end the process.

In step 2, it is checked whether the bill checker 13 has completed the authenticity determination of the banknotes.

This determination is made, for example, by providing a determination completion flag area in the storage device of the CPU 60 and based on the state of this flag.

This flag is set by a determination completion signal from the bill checker 13, and is reset when the bill return process is completed and each time a bill is inserted into the bill checker 13.

If the bill checker 13 has completed the authenticity determination of the banknotes, the process proceeds to step 3, in which the genuine banknotes sent out from the bill checker 13 are temporarily held in the drum 21 (step 3), and then the held banknotes are temporarily held in the drum 21 (step 3). Return the banknotes you have on Route 43
The item is then returned through the return port 12 (step 4).

The processing in step 3.4 is the same whether there is one banknote or two or more banknotes in the banknote processing device.

If the authenticity determination of the banknotes has not been completed, the process moves to step 5 and the banknotes in the bill checker 13 are returned from the insertion slot 11.

Next, it is checked whether the bill in the bill checker 13 is the first bill (step 6), and if it is not the first bill, that is, if it is the second or subsequent bill, the temporary holding mechanism 20 Since the banknote is on hold, the process moves to step 4 to return the banknote.

In the case of the first bill, the process ends.

The determination in step 6 is made based on the signal from the retained banknote detector 26.

As explained in detail above, according to the present invention, if a cancellation request is received while the bill checker of the bill processing device is determining the authenticity of a bill, the bill checker of the bill processing device immediately stops the authenticity determination process. Since the banknotes in the bill checker are returned to the banknote insertion slot, the time required for return is reduced by the sum of the time to determine the authenticity of the banknotes and the time to temporarily hold them in the temporary holding mechanism. be able to.

In addition, regarding banknotes held in the temporary holding mechanism,
Since the time required to transport the bills to the return slot is sufficient, the time required to distinguish the authenticity of the bills in the bill checker and then stack them with the bills in the temporary retention mechanism to temporarily retain the bills can be shortened.

Therefore, the time required for the cancellation process can be significantly shortened, the waiting time of the customer can also be shortened, and the efficiency of sales or transaction processing of the banknote handling device can be improved.

In addition, there is no need to convey the banknotes in the bill checker to the temporary holding mechanism and temporarily hold them therein, and since the reverse function of the conveyance mechanism in the bill checker is utilized, the cancellation processing control is also simplified.
