Description

TECHNICAL FIELD The present invention relates to a bill storage device in a bill device used in an automatic vending machine, a money changer, or the like.

[Conventional technology]

Banknote machines used in vending machines, money changers, etc.
Usually, it is composed of a bill validator for discriminating the authenticity and denomination of inserted bills, and a bill storage device for storing bills received as true coins as a result of the discrimination. Various types of banknote storage devices have been conventionally known. A bill storage device itself that can refund the stored bills is known, and a bill storage device itself that can stack two types of bills separately is also known.

For example, JP-A-59-20091 and JP-A-59-52
No. 395 shows a configuration in which a stacking type banknote storage device that cannot return banknotes and a winding type banknote storage device that can return banknotes are sequentially connected along a banknote passage. Further, Japanese Patent Application Laid-Open No. 59-75387 discloses a structure in which banknote stacking units are provided above and below a banknote passage and are sorted into upper and lower banknote stacking units according to the type of banknotes. There is. In this case, the bills stored in the upper and lower bill stacking units can be returned.

[Problems to be Solved by the Invention]

However, the conventional banknote storage device having such a special function has a drawback that the configuration becomes large. For example, a banknote storage device capable of refunding the banknotes once stored requires a fairly large-scale banknote discharging mechanism, and a winding type banknote storage device limits the number of banknotes to be stored, and There was a problem that it had a winding habit.

Further, in the banknote storage device in which two types of banknotes can be separately stacked in the upper and lower banknote stacking units, the stored banknotes cannot be returned.

The present invention has been made in view of the above-mentioned points, and it is possible to separately store two types of banknotes while having an extremely compact structure, and to store each banknote in a very simple configuration. It is an object of the present invention to provide a bill storage device that can be refunded as needed by an ejection mechanism.

Further, the present invention provides a banknote storage device which has an extremely compact structure and can store the banknotes in two types separately and can appropriately perform refund control on the stored banknotes. The purpose is to do.

[Means for achieving the task]

The banknote storage device according to the present invention includes a banknote transport path, a transport means for transporting the banknotes sent to the banknote transport path to a predetermined position for storage, and is formed on both sides of the banknote transport path. It is possible to reciprocate between the first and second banknote storage chambers each having a banknote return port, and the first and second banknote storage chambers through the banknote transport path. When storing a bill at a predetermined position of the transport path in the first bill storage chamber, the bill is moved to the first bill storage chamber from the second bill storage chamber toward the first bill storage chamber while moving the bill on the first side. The banknotes are stored by pressing with, while the banknotes are stored in the second banknote storage chamber while moving from the first banknote storage chamber toward the second banknote storage chamber. Press the bill with a second surface opposite the first surface A banknote pressing member for storing the banknotes, and a banknote conveying member provided in the banknote pressing member and exposed on the first and second surfaces of the pressing member. And a bill discharging mechanism for discharging the bill in contact with the conveying member to the bill return port.

Furthermore, the present invention further comprises control means for performing control for discharging banknotes from at least one of the first and second banknote storage chambers.

[Action]

Since two banknote storage chambers are provided on both sides of the banknote transport path so that different types of banknotes can be stored in each banknote storage chamber, the two banknote storage chambers are formed as an integral storage structure. It is very compact.

In addition, a bill pressing member that performs a pressing operation for storing bills in the bill storage chamber passes through the central bill transport path and reciprocates between the bill storage chambers to store bills in both bill storage chambers. Since it is a configuration shared by the operations, it is not necessary to provide a bill storage mechanism for each bill storage chamber.
The configuration can be simplified.

Further, both the first and second banknote storage chambers each have a banknote return port, and the banknote transport member of the banknote discharging mechanism is exposed on the first and second surfaces of the banknote pressing member, respectively. Since the carry-out operation is performed on the surface, it is possible to stack two different types of banknotes in different denominations and, when a refund is required, to refund the banknotes of both denominations respectively. Further, since the bill discharging mechanism is provided inside the bill pressing member, the structure of the bill discharging mechanism is simplified and the entire apparatus can be made considerably compact.

Reference numerals 91 and 92 denote pressing plates that press inward the cash vouchers stored in the cash voucher storage chambers 41 and 42 by the spring 9. 10 is a bill receiving plate provided on both sides of the bottom of the bill storage chambers 41 and 42.
Reference numeral 11 indicates a bill impeller and an impeller for delivering bills.

The banknote pressing member 7 is a first banknote that is frequently used and is stored in one banknote storage chamber 41 during standby, for example, 1,000 banknotes.
It is in a standby state for receiving yen bills (hereinafter referred to as bill R), that is, in a state of being stopped at a predetermined position A in the other bill storage chamber 42. After the banknote R has completely entered the banknote transport path 3, the banknote pressing member 7 moves toward the storage chamber 41, presses the banknote R to the rear of the rib 51, and then returns to the standby position A and stops. On the other hand, a second banknote that is relatively infrequently used, such as a 10,000-yen banknote or a 5,000-yen banknote (hereinafter banknote L
When it is notified by the bill validator X that the bills will be accepted, the bill pressing member 7 moves from the standby position A to the storage chamber 41, and stops at the standby position B for stacking the bills L, and the bill L Wait for delivery. After the banknote L has completely entered the banknote transport path 3 in this state, the banknote pressing member 7 moves to the storage chamber 4
The banknote L is moved to the position 2 and pressed to the rear of the rib 52 of the second banknote storage chamber 42, and stopped at the standby position A.

If you plan to return the bill R of the first bill accommodating chamber 41, the rear surface of the bill press member 7 is moved to the bill press member 7 to refund position C to be directly below the return opening 40 ₁ (in Figure 3 the solid line 7 see), the upper feed and to the return port 40 ₁ by the counterclockwise rotation of the roller -82 of the banknote R a piece of bill discharge mechanism 8 which is in contact with the back side of the bill pressing member 7 in this state.

If you plan to return the banknotes L of the second banknote storage chamber 42, moves the bill pressing member 7 to the refund position D where the surface of the bill press member 7 is just below the return opening 40 ₂ (FIG. 3 two-dot chain line Of 7
See), the upper feed and to the return port 40 ₂ by the clockwise rotation of the roller 82 of the bill discharge mechanism 8 An banknotes L which is in contact with the surface of the bill press member 7 in this state.

Note that the banknote pressing member 7 is positioned at the receiving standby positions A and B or the refund positions C and D by using outputs of a plurality of position detection switches that detect that the reciprocating mechanism 6 has reached each position. It may be controlled, or may be controlled by using one switch for detecting the reference position of the reciprocating mechanism 6 and outputs of a plurality of timers started by turning the switches ON and OFF. .

The operation of the apparatus shown in FIGS. 1 to 4 may be controlled by a microcomputer as described below according to the flowcharts shown in FIGS. 5 to 12.

The state where the banknote pressing member 7 is at the position A for stacking the banknotes R that are frequently used is referred to as the standby state of the banknote storage device.

When a bill is inserted into the bill discriminating apparatus X, the bill is optically and magnetically inspected to determine whether the bill is authentic or false (step 100). When it is determined that the bill is a fake bill, the feeding mechanism of the bill discriminating apparatus X is reversed and the bill is returned to the insertion slot.

When the bill validator X determines that the bill is a genuine bill, the stack operation is not immediately performed. The inserted bills are temporarily held in the bill validator X in a returnable state until a signal (hereinafter referred to as a sale start signal) indicating that the vending machine or the money changer has sold or exchanged money is given. There is. In this temporary holding state, when there is a sales start signal, a bill taking signal is given, and the stack operation starts only by the bill taking signal.

(In the case of banknote R) When the inserted banknote is of R type, the process proceeds from step 101 to step 102 and waits until the banknote take-in signal is given. When a bill return signal is given during this period, the bill return process is performed and the standby state is returned (steps 103 and 10).
4).

When the bill take-in signal is given, the bill R is fed into the bill inlet 2 by the feeding mechanism of the bill validator X. When the step SW ₁ provided in front of the bill inlet 2 detects the fed bill (YES in step 105), the timer T ₀ is started and the motor MO ₁ and the solenoid SOL are operated (step 106.107). . As a result, the bill is sent downward along the transport path 3. When the trailing edge of the bill leaves the switch SW ₁ , the timer T ₁ is started (steps 108 and 109). On the other hand, when the trailing edge of the bill does not slip out of the switch SW ₁ during the timer T ₀ , it is regarded as a failure and the process goes to “SET STOP” (step 110). The set time of the timer T _{0 is} a time normally required for one stacking cycle of bills, and is a timer for monitoring whether or not the stacking operation is completed within this time. On the other hand, the set time of the timer T _{1 is} a time corresponding to the time when the bill reaches the predetermined position corresponding to the pressing member 7 in the transport path 3.

In step 111, it is checked whether or not the set time of the timer T ₁ has passed. During the operating time of the timer T ₁ , step 1
Switch SW ₅ provided at the lower end of the banknote transport path 3 at 12
Check whether or not a bill has been detected by. Depending on whether the set time of the timer T ₁ has passed or a bill is detected by the switch SW ₅ , the process proceeds to step 113, and the solenoid SOL of the motor MO ₁ is turned off. As a result, the bill stops at a predetermined position on the transport path 3 corresponding to the pressing member 7, and the belt 33 and the roller 34
It is released from the state of being sandwiched between and. It should be noted that turning off the motor MO ₁ and the solenoid SOL may be controlled only by the condition of either the timer T ₁ or the switch SW ₅ .

Next, it is confirmed that the solenoid SOL is turned off (step 114), and the motor MO ₂ is turned on (step 115). As a result, the bill pressing member 7 moves from the standby position A shown in FIG. 1 to the right in the figure to push the bill in the transport path 3 and pushes the bill at the rear (right side in the figure) bill storage chamber. Stack at 41. After that, as the motor MO ₂ continues to rotate, the bill pressing member 7 returns to the left in FIG. 1, returns to the standby position A, and stops. The stack operation for one cycle is controlled according to the outputs of the switches SW ₂ and SW ₃ . That is, after the rotation of the motor MO ₂ is started, the switch SW ₂ is turned off and the switch S ₂ is sequentially turned on.
W ₃ turns on, switch SW ₃ turns off, switch S
Or W ₂ is ON (in other words, the pressing member 7 the switch SW
₂₎ the position A corresponding to ₂ is reached, the position B corresponding to the switch SW ₃ is reached, then the position B is left, and finally the position A is reached) is confirmed in steps 116 to 119, and all are satisfied. Then, the motor MO ₂ is stopped and the timer T
₀ is reset to complete the stack operation (step 1
20, 121). If the stack operation is not completed within the time period of the timer T ₀ , it is regarded as a failure and the process goes to “SET STOP” (step 122).

(In the case of banknote L) When the inserted banknote is L type, from step 101 to the sixth
Proceeding to step 123 in the figure, the motor MO of the reciprocating mechanism 6 is moved.
Rotate ₂ . As a result, the bill pressing member 7 moves from the standby position A shown in FIG. 1 to the right in the drawing. Switch SW ₂ is OFF, the switch SW ₃ To verify that the turned ON, stops the motor MO ₂ (step 124 to
126). In this way, the bill pressing member 7 is set to the standby position B shown by the chain double-dashed line in FIG. Next, the same processing as the processing from steps 102 to 113 in FIG. 5 is performed. That is, when a bill take-in signal is given, the bill is sent into the conveyance path 3, and when the bill is conveyed to a predetermined position corresponding to the pressing member 7 in the conveyance path 3, the conveyance of the bill is stopped and The bill is released from the state of being sandwiched between the belt 33 and the roller 34. Further similarly to step 114 of FIG. 5 is performed, the motor MO ₂
The reciprocating mechanism 6 is driven by driving. This allows
The banknote pressing member 7 moves from the standby position B shown in FIG. 2 to the left in the figure to press the banknote in the transport path 3 and stacks the banknote in the banknote storage chamber 42 on the front side (left side in the figure). . Switch SW ₂ is OFF, the switch SW ₂ To verify that the turned ON, stops the motor MO ₂ (Step 1
27-129). In the next steps 130 to 133, the solenoid SOL is turned on for the operating time of the timer T3.
Finally, the timer T ₀ is reset to complete the stack operation (step 134). In the same manner as described above, if the stack operation is not completed within the time of the above-mentioned timer T ₀ , it is regarded as a failure and the process goes to “SET STOP” (step 135).

(Refund operation of bill R) When a refund signal for instructing to refund the bill R or L stored in the bill storage chamber 41 or 42 is given to the control device such as the vending machine or the money changer, the operation shown in FIG. Execute the process.

First, in step 136, it is checked whether the refund signal commands the refund of one of the banknotes R or L. If the banknote is the banknote R, the process proceeds to step 137 to drive the motor MO ₂ .
After the processing of subsequent steps 138 to 142, the motor MO ₂
To stop. As a result, the bill pressing member 7 moves from the position A in FIG. 2 to the right in the drawing to the position B while pressing the bill bundle R in the bill storage chamber 41, and then the motor MO.
By continuing the rotation of ₂ , the bill pressing member 7 returns to the left in the drawing and stops at the position C in FIG. This operation is controlled according to the outputs of the switches SW ₂ , SW ₃ and the timer T ₄ . That is, after starting the rotation of the motor MO ₂ ,
In order, the switch SW ₂ is turned off, the switch SW ₃ is turned on, and the switch SW ₃ is turned off (that is, the pressing member 7 leaves the position A corresponding to the switch SW ₂ and moves to the position B corresponding to the switch SW _3). Is reached, and then the position B is left) is confirmed in steps 138 to 140, and the motor MO ₂ is stopped when the time of the timer T ₄ started when the switch SW ₃ is turned off has elapsed. Timer T
The time of ₄ is set to a time corresponding to the time required for the bill pressing member 7 to move from the position B to the position C.

With the bill pressing member 7 positioned at the position C, the motor MO ₃ of the bill discharging mechanism 8 is rotated in the normal direction (the rotation of the motor MO ₃ that causes the roller 82 to rotate in the counterclockwise direction in the figure is defined as the normal rotation, The rotation of the motor MO ₃ that gives the rotation in the opposite direction is reversed), the roller 82 rotates counterclockwise,
Banknote storage chamber 41 in contact with the contact surface 83 of the roller 82
The leftmost banknote of the banknote bundle R is sent out upward (step 144). The fed bill passes through the impeller 11 through the return port 40 _1, enters the bill discrimination apparatus X.

2 ply detection switch SW ₄ is made of a quantity of transmitted light detection switch for detecting whether or not a bill is sent out by the two-ply and is provided at the same position as the switch SW ₁ (special in this embodiment It is assumed that the switch SW ₁ is shared without providing the switch SW ₄ ). The tip of the bill sent upwards is a double-sheet detection switch SW
_When the position ₄ is reached, step 145 becomes YES,
Proceeding to step 146, the motor MO ₃ is intermittently operated.
The intermittent operation of the motor MO ₃ is performed in order to shake off the extra bill that is not in contact with the contact surface 83 of the roller 82 when the bills are fed in a stack of two bills (including two or more bills). During this intermittent operation, the output of the switch SW ₄ is analyzed to determine whether one or two or more banknotes are being sent out. This judgment is made by a known light quantity level discriminator or the like for judging the transmitted light quantity level detected by the switch SW ₄ .

If it is determined that there is no overlapping of two sheets, ON in step 147
To Steps 148 and 149. Here, the rear end of the bill passes through the switch SW ₄ so that the switch S
The motor MO ₃ is rotated until W ₄ is turned off, and when the switch SW ₄ is turned off, the motor MO ₃ is stopped. Although not shown, the refund signal and the switch SW ₄ O
The bill feeding mechanism of the bill discriminating apparatus X starts a reverse operation according to N, and the bill returned from the bill storing device is further transferred and returned to the bill insertion slot.

In this way, one banknote is returned. Step 1 in FIG. 7
At 50, it is further checked whether or not the refund signal is continuously given. If NO, the motor MO ₂ is rotated to move the bill pressing member 7 from the position C in FIG. 3 to the left in the drawing (step 151). ). When the bill pressing member 7 reaches the standby position A, the step SW ₂ is turned on (step 152) and the motor MO ₂ is stopped (step 153).

In case of consecutive refunds, the process proceeds from YES in step 150 to steps 154 and 155 in FIG.
₂ is rotated to move the bill pressing member 7 from the position C in FIG. 3 to the left in the drawing, and it is confirmed that the pressing member 7 has reached the standby position A by turning on the switch SW ₂ . Then, the process returns to step 138 in FIG. 7 and the bill refund processing similar to the above is repeated. As described above, the reason why the bill pressing member 7 reciprocates every time one bill is discharged at the time of continuous refund is the third one.
This is because if the banknotes are continuously ejected while the banknotes are being pressed at the position C in the figure, double ejection is likely to occur, and this is prevented.

(Refund operation of banknote L) When a refund signal for instructing the refund of the banknote L stored in the banknote storage chamber 42 is given from a control device such as a vending machine or a money changer, a step from step 136 in FIG. In step 156 of FIG. 10, the motor MO ₂ is driven. The motor MO ₂ is stopped through the processes of the following steps 157 to 160. As a result, the bill pressing member 7 moves from the position A to the right in the drawing and stops at the position D in FIG. That is, after the rotation of the motor MO ₂ is started, the switch SW
₂ is turned off, and the motor MO ₂ is stopped when the time of the timer T5 which starts when this switch SW ₂ is turned off has elapsed. The time of timer T5 is the bill pressing member 7
Is set to a time corresponding to the time required to move from position A to position D.

With the banknote pressing member 7 positioned at the position D, the motor MO ₃ of the banknote discharging mechanism 8 is reversely rotated, the roller 82 rotates clockwise, and the banknote storage chamber 42 in contact with the contact surface 83 of the roller 82. The rightmost banknote of the banknote bundle L is sent out upward (step 161). The fed bill passes through the impeller 11 through the return slot 40 _2, enters the bill discrimination apparatus X. Subsequent steps 162 to 167 are the same as steps 145 to 150 in FIG.
The banknotes are ejected so that they are not ejected in piles of more than one.

The process of steps 168 to 171 when the continuous refund is not performed is the same process as steps 137 to 140 of FIG. 7, and the bill pressing member 7 is once moved to the position B and then returned to the standby position A. Then, the motor MO ₂ is stopped (step 172).

If the refund is to be made continuously, the process proceeds from YES in step 167 to the process shown in FIG. The process of FIG. 12 is the same as the process of steps 168 to 171 of FIG. 10, in which the bill pressing member 7 is once moved to the position B and then returned to the standby position A. Next, returning to step 157 in FIG. 10,
The bill refund processing similar to the above is repeated.

(When Two-Folding is Detected) When two-folding is detected during the discharging operation of the bill R, the process proceeds from YES in step 147 in FIG. 7 to the process in FIG. Here, the motor MO ₃ is reversed to store the bills in the storage chamber 4
Return to 1. When the trailing edge of the bill leaves the switch SW ₄ ,
Start timer T2, when the time of the timer T2 has elapsed, to stop the motor MO _3. The set time of the timer T2 is a time corresponding to the return of the bill to the storage chamber 41. Next, the motor MO ₂ is rotated to move the bill pressing member 7 from the position C in FIG. 3 to the left in the drawing, and the switch SW ₂
It is confirmed that the pressing member 7 has reached the standby position A by turning on, and that the pressing member 7 has moved from the standby position A to the right in the figure by turning off the switch SW ₂ . Then, the process returns to step 139 in FIG. 7 to re-execute the bill refund processing similar to that described above.

When the stack of two bills is detected during the discharging operation of the bill L, the process proceeds from YES in step 164 of FIG. 10 to the process of FIG. Here, the motor MO ₃ is normally rotated to return the bill to the storage chamber 42. The timer T ₂ is started when the trailing edge of the bill leaves the switch SW ₄ , and the motor MO ₃ is stopped when the time of the timer T ₂ has elapsed. Next, the motor MO ₂
Is rotated to move the bill pressing member 7 from the position D in FIG. 3 to the right in the drawing, and it is confirmed that the pressing member 7 has reached the position B by turning on the switch SW ₃ , and further the switch SW ₃
It is confirmed that the pressing member 7 has moved from the position B to the left in the figure by turning OFF the switch, and that the pressing member 7 has reached the position A by turning the switch SW ₂ ON. And
Returning to step 157 in FIG. 10, the bill refund processing similar to the above is re-executed.

In the example shown in the figure, the above routine is repeated any number of times until the two-ply overlap is no longer detected. However, if the two-ply overlap is not resolved even after the number of repetitions is set and the number of repetitions is set, a failure occurs. May be considered.

〔The invention's effect〕

As described above, according to the present invention, the housing of the banknote storage device is divided into front and rear to form a banknote storage chamber, and the inserted banknotes are divided into two types and stored in the respective storage chambers, and once stored. Since the bills can be returned, it is possible to provide a small and compact bill storage device that is highly functional and yet has an excellent effect. In addition, since it is possible to return the stored banknotes to each storage room, for example, two kinds of banknotes of a denomination are used, and a banknote of a common denomination is stored in each storage room. If the return control of the banknotes is performed, there is an excellent effect that two kinds of banknote denominations that can be used as change can be used even though the banknotes have a compact structure.
