Abstract

PURPOSE:To easily and surely detect a foreign material when it is attached on a bill by detecting the impedance change of a detecting coil means and judging the existence of the foreign material based on the output. CONSTITUTION:When a metallic foreign material or the foreign material having magnetism comes into a generated magnetic field by a detecting coil 12, an eddy current by an electromagnetic induction action is generated inside the foreign material, and the eddy current generates the magnetic field in a direction to cancel the magnetic field by the detecting coil 12. Thus, as the foreign material approaches the detecting coil, the impedance of the detecting coil 12 increases gradually and reduces the oscillation amplitude of an oscillating circuit 14, and when the oscillation amplitude is lowered under a fixed level, a monostable flip flop circuit 16 is activated and a foreign material detecting signal is outputted from an output circuit 17 to a control signal output means 19. Then, a driving inhibiting signal and an alarm signal are outputted. Thus, a foreign material A can be detected easily and surely, and the paper jamming and the breakage of a feeding mechanism can be surely prevented.

[Examples] Hereinafter, examples of the first invention and the second invention will be described in detail based on the accompanying drawings.

FIG. 1 is a schematic side view showing the main parts of a banknote deposit machine according to an embodiment of the present invention, and FIG. 2 is a block diagram of a foreign matter processing device of the banknote deposit machine.

In FIG. 1, the banknote input section 1 is composed of a fixed clamping plate 2, a movable clamping plate 3, and a bottom plate 4, and banknotes 5 are input into the banknote input section 1 from a banknote input slot (not shown). In FIG. 1, the left side shows the four coins in front of the banknote deposit machine. The movable clamping plate 3 is biased toward the front of the banknote deposit machine, that is, toward the fixed clamping plate 2, by a spring (not shown), but when the banknote is in use, the fixed clamping plate 2 is biased by a regulating member (not shown). Its position is regulated so that there is a space between which banknotes can be inserted. When the banknote insertion operation is completed and the start switch 22 shown in FIG. Pushed forward by the spring, the bill 5 is clamped between the fixed clamping plate 2 and the movable clamping plate 3.

A pair of kick-out rollers 6 are provided on the back side of the fixed clamping plate 2.
They are spaced apart in the direction perpendicular to the paper surface of the figure, and each
It faces into the banknote input section 1 through a window (not shown) of the fixed clamping plate 2 and is in contact with the surface of the frontmost banknote 5 clamped between the fixed clamping plate 2 and the movable clamping plate 3. Below the kick-out roller 6, there are provided a feed-out roller 7 for taking out banknotes from the banknote input section 1, and a separation roller 8 that comes into contact with the feed-out roller 7 and rotates in a direction opposite to the feed-out direction. The bill 5 is kicked downward by the kick-out roller 6, and is fed out from the bill input section l by the feed-out roller 7, but at this time, the frictional force between the bill and the separation roller 8 prevents two-sheet feeding. ,
It is configured to be fed out one by one. The kicking roller 6, the feeding roller 7, and the separation roller 8 are configured to be driven by a feeding motor 9. A is a foreign object consisting of a clitoris and a knob.

Furthermore, a printed circuit board I is provided on the front surface of the fixed clamping plate 2.
O is attached. The printed circuit board IO has a second
As shown in the figure, windows 11a and 11b are provided on both sides of the stationary clamping plate 2 at positions corresponding to the windows provided in the fixed clamping plate 2, and a spiral printed wiring is provided on the detection coil 12. is formed, and the detection coil 12 is connected to an impedance change detection means 13.

The impedance change detection circuit 13 includes an oscillation circuit 14 that continues to oscillate at a certain frequency and amplitude in cooperation with the detection coil 12, an amplifier circuit 15 that amplifies and extracts the oscillation signal of the oscillation circuit 14, and Monostable flip-flop circuit 1 that determines whether the oscillation amplitude of the oscillation platform number extracted by the amplifier circuit 15 is below a preset level.
6, an output circuit 17 that outputs the result determined by the monostable flip-flop circuit 16 as an output signal, and supplies a power supply voltage to the oscillation circuit 14, the amplifier circuit 15, the monostable flip-flop circuit 16, and the output circuit 17. It is composed of a power supply circuit 18. The impedance change detection circuit 13 cooperates with the detection coil 12 to
Within the operating range of the detection coil 12, that is, the detection coil 1
2 detects whether or not a foreign object is present in the generated magnetic field, and outputs an output signal to the control signal output means 19. That is, when a metallic or magnetic foreign object enters the magnetic field generated by the detection coil 12, an eddy current is generated inside the foreign object due to electromagnetic induction, and this eddy current cancels the magnetic field generated by the detection coil 12. Generates a magnetic field. Therefore, as the foreign object approaches the detection coil, the impedance of the detection coil 12 gradually increases, and the oscillation circuit 1
4, and when this oscillation amplitude falls below a certain level, the monostable flip-flop circuit 16 operates,
The foreign object detection signal from the output circuit 17 is sent to the control signal output means 19.
is output to.

The control signal output means 19 is constituted by a microcomputer, and when a foreign object detection signal is manually input from the impedance change detection means 13, it determines that there is a foreign object and controls the feeding motor control means 2 to control the driving of the feeding motor.
0, a drive prohibition signal is output, and an alarm signal is output to the alarm means 21. The feeding motor control means 20 prohibits the driving of the feeding motor 9 when a driving prohibition signal is input from the control signal outputting means 19, and the alarm means 21 receives an alarm signal from the control signal outputting means 19. When, the alarm display section 21a shows,
It is configured to display that a foreign object was contained and to emit a sound from the alarm audio output section 21b to the operator indicating that a foreign object was contained. 22 is a start switch, and when the insertion of banknotes 5 is finished,
Only when the start switch operation determination means 23 detects that the start switch operation determination means 23 detects that the start switch is turned on by the operator, the feeding of the banknotes 5 into the banknote deposit machine and the detection of foreign objects are started.

FIG. 3 is a flowchart showing the operation of the foreign matter processing apparatus according to the embodiment of the first invention shown in FIGS. 1 and 2.

In FIG. 3, when the insertion of banknotes 5 is completed, the start switch operation determination means 23 determines whether the start switch 2
2 is turned on or not. As a result, no operation is performed when the start switch 22 is not turned on. On the other hand, when it is determined that the start switch 22 is turned on, the detection coil 12 and the impedance change detection means 13 detect whether or not the foreign object A is present.

As a result, when the foreign object A is detected, the impedance change detection means 13 outputs a foreign object detection signal to the control signal output means 19. The control signal output means 19 outputs a drive prohibition signal to the feeding motor control means 20 and an alarm signal to the alarm means 21 based on this foreign object detection signal. The feeding motor control means 2o is
In response to the drive prohibition signal, the drive of the payout motor 9 is prohibited and not started, and the alarm means 21 visually displays on the alarm display section 21a that a foreign object has been mixed in the banknote 5 in accordance with the alarm signal. Then, a sound to that effect is outputted from the alarm sound output section 21b.

On the other hand, when the foreign object A is not detected, the feeding motor 9
However, the kicking roller 6, the feeding roller 7, and the separation roller 8 are driven, and the banknote 5 inserted into the banknote input section 1 is only fed out into the banknote deposit machine. Then, when the feeding of all the inserted banknotes 5 is completed without detecting the foreign object A, the foreign object detection operation ends.

On the other hand, when the detection coil 12 and the impedance change detection means 13 detect the object A after the start of feeding out the banknote 5, the impedance change is detected in exactly the same way as before the start of feeding 1/ψ operation. The detection means 13 outputs a foreign object detection signal to the control signal output means 19, and in response, the control signal output means 19 outputs a drive prohibition signal to the feeding motor control means 20, and the alarm means 21 An alarm signal is output to the feed motor 9, and at the same time as the feeding motor 9 is driven or stopped, an alarm display and an alarm sound are output.

In addition, when a foreign object is detected and the feeding operation of the banknote 5 is not started or stopped, and an alarm display and alarm sound are output,
Foreign matter A mixed into the banknotes 5 is removed by the banknote deposit machine.

For example, if a foreign object is detected before the start of the operation to feed out the inserted banknotes 5, the shutter of the banknote slot is automatically opened, allowing the operator to remove the foreign object A himself. Furthermore, if a foreign object is detected after the feeding operation of the inserted banknotes 5 has started, an alarm is displayed to the administrator of the banknote deposit machine at the same time, so that the administrator can It is also possible to remove foreign substances.

As described above, in this embodiment, even if a foreign object is attached to the banknote 5, this can be easily and reliably detected, and when a foreign object is detected, the feeding of the banknote is immediately prohibited. Therefore, it is possible to reliably remove foreign objects, and it is possible to reliably prevent the banknotes 5 from getting stuck in the feeding mechanism of the banknote deposit machine or damaging the feeding mechanism due to foreign objects. .

FIG. 4 shows another example of wiring of the detection coil 12 printed and wired to the printed circuit board 10. In FIG. 4, there are four detection coils 12 in the center of the printed circuit board 10, and two detection coils 12 on the outside of windows 11a and Ilb provided on the printed circuit board 10 so that they can come into contact with the kicking roller 6 or the bill 5. A total of eight detection coils 12 are provided.

Generally, t of foreign matter A with respect to the wiring area of the detection coil 12
As the target size becomes smaller, the change in the impedance of the detection coil I2 due to the foreign object A becomes smaller, so it is recommended to provide a plurality of detection coils 12 as shown in FIG. It is desirable to do so. In addition, in order to improve the detection accuracy of foreign matter A, it is preferable to provide the detection coil 12 so as to cover the entire surface of the banknote 5 so that the entire surface of the banknote 5 is included in the operating area of the detection coil 12. As shown in Figure 4, 'fV number detection coil 1
When installing 2, the flexibility of the arrangement is high.
It is preferable from this point of view as well. As shown in FIG. 4, the detection coil 12? If ul is provided, it is necessary to provide a plurality of impedance change detection circuits I3#) connected to it, and the output signals of the 19 impedance change detection circuits 13 are connected to the control signal output means 19 by OR connection. If a foreign object is manually detected by any one of the detection coils 12 and the impedance change detection circuit 13, the bill is prohibited from being fed out.

FIG. 5 is a schematic side view showing the main parts of the banknote deposit machine according to the embodiment of the second invention, and FIG. 6 is a block diagram of the foreign matter processing device of the banknote deposit machine.

In FIG. 5, the banknote input section I is formed by a pair of movable clamping plates 30a, 30b and a bottom plate 4, and is in a position retracted backward relative to the fixed plate 32, into which banknotes 5 are inserted.
When receiving the input banknotes 5 and feeding them into the banknote deposit machine, the transfer motor 31 shown in FIG.
, it is transferred forward toward the fixed plate 32, and the fixed plate 32
It is constructed so that it can be positioned at a feeding position near the. The reason for locating the bill insertion part l at a position away from the feeding position when inserting banknotes in this way is that when the banknote 5 is to be handled at the feeding position, the banknote 5 can be inserted by the banknote 5 by the banknote 5 clerk. Bill insertion section 1
This is to prevent the adjustment state of the kicking roller 6, feeding roller 7, and separation roller 8, which are pushed out more, from changing, and making it impossible to perform the desired feeding operation of the banknote 5.

The fixed number 32, kick-out roller 6, feed-out roller 7, and separation roller 8 are provided in the same positional relationship as the fixed clamping plate 2, kick-out roller 6, feed-out roller 7, and separation roller 8 in FIG. It is being However, the print board i10 is attached to the one movable clamping temporary 30a, and is used to determine whether foreign matter A is mixed in the input banknotes 5 that are clamped by the pair of movable clamping plates 30a and 30b. ′
You can also set the bottom (
On the other hand, a hole (not shown) is provided between the 1st banknote insertion position and the banknote payout position, so that the banknote 5 can be placed at -λ・j
While being held between the movable clamping plates 30a and 30b of the banknotes 5 and being transferred from the banknote official position to the banknote dispensing position, foreign matter mixed in the banknotes 5 simply falls down through this hole and is removed from the collection L (not shown). The fM is configured such that 14 stages are collected.

Referring to FIG. 6, in this embodiment, unlike the case of FIG. 2, the impedance change detection means 13
When a foreign object detection signal is manually input to the control signal output means I9, before the transfer motor 31 transfers the banknote input section 1, the control signal output means I9 outputs the transfer control means 33 which controls the drive of the transfer motor 3I. At the same time, the control signal output means 19 outputs a transfer prohibition signal to the alarm means 21 and outputs an alarm signal to the alarm means 21 .
and an alarm signal to the alarm means 21, respectively, and transfer control means 3.
3, the foreign matter processing device is configured to output a reverse transport signal.

FIG. 7 is a flowchart showing the operation of the foreign matter processing apparatus according to the embodiment of the second invention shown in FIGS. 5 and 6.

In FIG. 7, when the banknote 5 is completed, the start switch is operated 1. The lJ determining means 23 determines whether the start switch 22 is turned on or not by 1'lJ. As a result, no operation is performed when the start switch 22 is not turned on. On the other hand, when it is determined that the start switch 22 is turned on, the detection coil 12 and impedance change detection means 13 of the printed board [10 attached to the front movable clamping plate 30a detect whether or not there is a foreign object A. Ru.

As a result, when the foreign object A is detected, the impedance change detection means 13 outputs a foreign object detection signal to the control signal output means 19. The control signal output stage 19 outputs a transfer prohibition signal to the transfer control means 33 based on this foreign object detection signal, and then outputs an alarm signal to the alarm means 21 at t). Along with this, the transfer control means 33 prohibits the transfer motor 31 from transferring the banknote input section l, that is, the pair of movable clamping plates 30a and 30b, and the alarm means 21 also prevents the transfer motor 31 from transferring the banknote input section l, that is, the pair of movable clamping plates 30a and 30b. The alarm display section 21a displays a message indicating that the alarm occurred, and the alarm audio output section 21b outputs a sound to that effect.

On the other hand, when the foreign object A is not detected, the control signal output means 19 outputs the transfer speed to the transfer control means 33, and the transfer control means 33 drives the transfer motor 31 to transfer the paper money to the banknote input section 1, that is, The pair of movable clamping plates 30a and 30b are transferred to the extended position.

When the banknote input section 1 is moved to the feeding position and a transfer detection means (not shown) detects that the print board attached to the front movable clamping plate 30a is brought into contact with the fixed plate 32, the feeding motor 9 is driven. and kick-out roller 6,
The feeding roller 7 and the separation roller 8 start feeding out the banknotes 5 in the banknote input section 1 into the banknote slot.

Then, when all the inserted banknotes 5 are fed out without detecting the foreign object A, the foreign object detection operation ends.

On the other hand, when the foreign object A is detected by the detection coil 12 and the impedance change detection means 13 after the feeding of the banknote 5 is started, the impedance change detection means I3 sends a foreign object detection signal to the control signal output means 19. In response, the control signal output means 19 outputs a drive prohibition signal to the feeding motor control means 20 and an alarm signal to the alarm means 21, and at the same time, to the transfer control means 33, A reverse transfer signal is output, and at the same time as the feeding motor 9 is driven or stopped, an alarm is displayed and an alarm sound is output.Furthermore, the transfer control means 33 causes the transfer motor 3 to rotate in the reverse direction, and the bill insertion section l is It is returned to the bill insertion position. I wanted to,
The detected foreign object A is also returned to the bill insertion position together with the bill 5 that has not been completely fed out.
When foreign object A is detected, foreign object A is always
′≦, it is located at the banknote insertion position.

Note that when the foreign object A is detected and the transfer of the banknote input section 1 is not started and the alarm display and alarm sound are output, or when the foreign object A is detected and the banknote feeding section 1 is not started, or after the start of the feeding operation of the banknote 5, the foreign object is detected and the banknote 5's? a) Operation or stop of dispensing, alarm display and output of alarm sound, and bill insertion section 1
When the 1σ return to the banknote insertion position is made, the foreign matter A mixed in the banknote 5 is removed from the banknote deposit machine by a desired method. For example, if a foreign object A is detected before the bill insertion section 1 is transferred, the shutter of the banknote insertion slot may be automatically opened, allowing the operator to remove the foreign object A himself or herself. If a foreign object A is detected after the start of feeding t/ψ of the input banknote 5, an alarm is displayed to the administrator of the banknote deposit machine at the same time. It can also be removed. Furthermore, in this embodiment, when a foreign object is detected, the foreign object is always returned to the bill insertion position. The shutter of the bill insertion slot may be opened in conjunction with the return of the machine to the bill insertion position, so that the operator himself or herself can remove foreign objects.

As described above, in this embodiment as well, if the foreign object A is attached to the banknote 5, it can be easily and reliably detected, and when a foreign object is detected, the banknote is immediately stopped from being fed out. The banknotes that are prohibited and have not yet been dispensed will be returned to the banknote insertion position, allowing the banknotes to be removed. Banknotes 5 were stuck in Xin Xian's delivery fee,
