Description

Description: TECHNICAL FIELD The present invention relates to a foreign matter processing device for a banknote deposit machine capable of detecting a foreign matter that has been inserted together with a bill and removing the foreign matter.

[Prior Art] When a foreign matter is mixed in a bill inserted into a bill insertion slot, the foreign matter may be jammed in a bill feeding mechanism or the like, obstructing the bill feeding, or causing a failure of the feeding mechanism. Therefore, various methods have been proposed to detect foreign matter and remove it.

For example, in JP-A-62-125489, a pair of rods are attached to the bottom of the bill insertion slot in a direction that traverses the inserted bills, and the inserted bills are supported by these rods, while the other is inserted together with the bills. An apparatus has been proposed in which the removed foreign matter is collected by dropping it below the space between the pair of rods.

[Problems to be Solved by the Invention] According to this device, it is possible to remove most of the foreign matter that has been inserted together with the bill, but since the foreign matter is naturally dropped, it is possible to remove it. When foreign matters such as clips and insect pins are attached to bills, it is impossible to remove them.

For this reason, when a plurality of banknotes are inserted while being integrally stopped by a clip or a bug pin, a roller or the like that feeds the banknotes into the banknote deposit machine through the banknote insertion slot pays out the plurality of banknotes. As a result, there is a problem that the banknotes are clogged in the roller portion, and it becomes impossible to pay out the banknotes thereafter. Further, if the foreign matter attached to the bill is made of metal, the feeding mechanism may be damaged, which may cause a serious problem that the article needs to be replaced.

It is an object of the present invention to provide a banknote depositing machine that can detect and remove foreign matter that has been inserted together with a banknote even if the foreign matter adheres to the banknote.

[Means for Solving the Problem] An object of the present invention is to provide a foreign matter for a banknote depositing machine that includes a banknote inserting unit capable of inserting a plurality of banknotes in a lump and a banknote delivering unit for delivering the banknotes of the banknote inserting unit to the inside. In the processing device, a bill feeding unit that feeds bills from the bill insertion unit to the bill feeding unit, a bill feeding control unit that drives and controls the bill feeding unit, and a bill feeding unit that is provided between the bill feeding unit and the bill feeding unit. A foreign matter detection roller that can be brought into contact with the surface of the bill sent by the bill feeding means and that can swing.
Based on the potentiometer that outputs a voltage signal corresponding to the swing of the foreign matter detection roller, and the output signal of the potentiometer, it is determined whether or not the foreign currency is mixed in the inserted bill, and the foreign matter is mixed. When it is determined that there is a control signal output means for outputting a reverse transfer signal to the bill feeding control means, and drivingly controlling the bill feeding control means so as to feed the fed bill back to the bill feeding portion, and the bill. This is achieved by including a bottom plate which is provided between the insertion section and the bill feeding means so as to advance and retreat to a position facing the bill insertion section, and which aligns the ends of the inserted bills.

Further, the foreign matter processing device of the bill depositing machine of the present invention further comprises:
An alarm means is provided, and the control signal output means outputs a reverse transfer signal to the bill feeding control means and also outputs an alarm signal to the alarm means when it is determined that the inserted bill contains foreign matter. The alarm means is configured to output an alarm when receiving the alarm signal.

[Operation] The present invention focuses on the fact that when a foreign matter is attached to or mixed in the inserted bill, the thickness of that portion becomes larger than that of the other portions, and therefore the foreign matter passes through the foreign matter detection roller. When the foreign matter detection roller swings, the output of the potentiometer that outputs a voltage corresponding to the swing of the foreign matter detection roller changes, and therefore the foreign matter is a metallic object such as a clip or pin. Needless to say, even if the bill is made of non-metallic material such as plastic, or if foreign matter is attached to the bill, the control signal output means can reliably detect it, and further If the bills are attached or mixed, the bills are always sent back to the bill insertion portion, so that the bills with foreign matter attached or mixed can be easily taken out from the bill depositing machine. Therefore, it is possible to prevent the bills from being jammed in the feeding mechanism of the bill depositing machine due to the foreign matter or from being damaged by the foreign matter.

Further, since the end portions of the bills inserted into the bill insertion portion are aligned with the bottom plate, the bills can be sent to the foreign matter detection roller in an aligned state, and thus the bills are not aligned. The detection failure due to the foreign matter detection roller, which may occur at any time, is prevented, and the foreign matter is satisfactorily and reliably detected.

Further, according to the present invention, when a foreign matter is mixed in the inserted bill, an alarm is output, so that the operator or the administrator of the bill depositing machine can immediately know that the foreign matter is mixed in and take out the foreign matter. It will be possible.

[Embodiment] An embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

FIG. 1 is a schematic side view showing a main part of a bill depositing machine according to an embodiment of the present invention.

In FIG. 1, the bill insertion portion 1 includes a fixed plate 2 and an X1-
It is composed of a movable plate 3 and a bottom plate 4 that are movable in the X2 direction, and the banknote 5 is inserted into the banknote insertion unit 1 through a banknote insertion slot (not shown). In Fig. 1, the left side corresponds to the front of the banknote deposit machine. For the fixed plate 2 and the movable plate 3,
Each has a window (not shown), and two sets of three first feed rollers 4A and 7B are provided to face each other so as to project from the window. . The three feed rollers 7A and 7B that constitute one set are arranged in the width direction of the banknote deposit machine, and
Is provided so as to be movable in the X1-X2 directions integrally with the movable holding plate 3. The movable plate 3 is retracted to the front at the time of inserting a bill, and its position is regulated so as to provide a space between the movable plate 3 and the fixed plate 2 which does not hinder the insertion of bills. When the bill insertion operation is completed and a start switch (not shown in FIG. 1) is turned on, a shutter (not shown) is closed, and in conjunction with this, the movable plate 3 is moved backward by a motor (not shown). As shown in FIG. 1, the banknote 5 is held between the feed roller 7A on the fixed plate 2 side and the feed roller B on the movable plate 3 side. After holding the bill 5, the feed rollers 7A and 7B are driven by a drive motor (not shown), the bottom plate 4 is moved in the X1 direction, and the bill 5 is fed downward in the transfer path 6. A indicates a pin that is inserted together with the inserted bill 5 and attached to the bill 5.

On the front side of the transfer path 6 below the bottom plate 4, three three feeding rollers arranged in the width direction of the banknote deposit machine are provided at positions facing the three second feed rollers 8 provided on the rear side of the transfer path 6. A foreign matter detection roller 9 is provided. A potentiometer 10 is provided below the foreign matter detection roller 9, and the rotary shaft 9A of the foreign matter detection roller 9 and the rotary shaft 10A of the potentiometer 10 are provided.
The foreign matter detection roller 9 is attached to the rotary shaft 10A of the potentiometer 10 via the link 11 so as to be swingable around the rotary shaft 10A of the potentiometer 10. At the lower end of the link 11, the spring 12
Is attached to one end, and the other end of the spring 12 is fixed to a fixing portion (not shown) of the bill depositing machine. The foreign matter detection roller 9 is biased toward the transfer path 6 by this spring 12 and is configured to come into pressure contact with the surface of the banknote 5 which is the first banknote to be transferred in the transfer path 6. Therefore,
When the foreign matter A such as a pin is attached to the inserted banknote 5, the foreign matter detection roller 9 swings forward because the thickness of the banknote 5 is larger than that of the portion where the foreign matter A is not attached. As a result, the potentiometer 10 rotates and the output voltage of the potentiometer 10 changes, so that it is possible to detect the mixing of the foreign matter A. Therefore, as shown in detail in FIG. 2A, the intervals between the ends of the three foreign matter detection rollers 8 are set to be sufficiently small so as to match the size of the foreign matter A to be detected. ing. The second feed roller 8 is also composed of three rollers, each of which is arranged in the width direction of the bill depositing machine so as to face the foreign matter detection roller 8, and is driven by the same motor (not shown) as the first feed rollers 7A and 7B. To be done. Foreign matter detection roller 9, potentiometer 10
The link 11 and the movable plate 3 and the first feed roller 7B are attached to a movable unit (not shown), and these are integrally configured so as to be movable in the X1-X2 directions. With respect to the thickness of the inserted banknote 5, the movable unit is moved so that the first feed roller 7A comes into contact with the front surface of the banknote 5, and thus the banknote 5
If the foreign matter A is not mixed in, the relative position of the foreign matter detection roller 9 with respect to the potentiometer 10 when the bill 5 is transported downward in the transport path 6 is immovable, and the potentiometer 10 rotates the rotary shaft 10A of the rotary shaft 10A. It doesn't rotate around. Therefore, even if the thickness of the inserted banknote 5 changes, the output voltage of the potentiometer 10 can be maintained constant as long as the foreign matter A is not mixed, and the foreign matter A can be detected accurately. .

Below the foreign matter detection roller 9 and the second feed roller 8,
Two sets of third feed rollers 13A and 13B, one set of three, are provided so as to face each other, and the foreign object detection roller 9 allows the movable holding plate to horizontally move the banknotes 5 whose foreign objects have been detected. 14, a fixed holding plate 15 and a bottom plate 16 for storing bills
It is configured to feed to 17. Third feed roller 13
A and 13B are also driven by the same motor that drives the first feed rollers 7A and 7B and the second feed roller 8.

On the back surface of the fixed holding plate 15, a pair of kick rollers 18 are provided.
They are provided in a direction perpendicular to the paper surface of the figure,
The fixed holding plate 15 faces the inside of the banknote storage portion 17 through a window (not shown) and is in contact with the front face of the banknote 5 held by the fixed holding plate 15 and the movable holding plate 14. Below the kick roller 18, a feeding roller for taking out the bill from the bill storing section 17 is provided.
19 and a separation roller 20 that is in contact with the separation roller 20 and rotates in a direction opposite to the feeding direction. The banknote 5 is kicked downward by the kick roller 18 and is paid out by the payout roller 19 from the banknote storage unit 17 toward the inside of the banknote deposit machine. At that time, due to the frictional force with the separating roller 20, Two sheets are prevented from being fed, and the sheets are fed one by one.

FIG. 3 is a block diagram of a foreign matter processing apparatus according to an embodiment of the present invention.

In FIG. 3, the output of potentiometer 10 is output to level determination means 30. Fig. 4 shows potentiometer
10 is a graph showing the output voltage V of 10 and, as described above, when the foreign matter A is not attached to or mixed with the banknote 5,
The output voltage V output from the potentiometer 10 to the level determination means 30 is substantially equal to the reference voltage Vo and is substantially constant. On the other hand, when the foreign matter A adheres to or is mixed in the inserted banknote 5, the portion of the banknote 5 where the foreign matter A adheres or mixes inevitably has a thickness larger than that of other portions. Therefore, when the foreign matter A passes between the foreign matter detection roller 9 and the second feed roller 8, the foreign matter detection roller 9 swings forward and the foreign matter detection roller 9 moves relative to the potentiometer 10. The position changes, and the potentiometer 10 rotates about its rotation axis 10A. Therefore, the output voltage V output from the potentiometer 10 to the level determination means 30 changes from the reference voltage Vo according to the increase in the thickness of the banknote 5 due to the presence of the foreign substance A, that is, the size of the foreign substance A. In FIG. 4, the output voltage of the potentiometer 10 is near the reference voltage Vo when the foreign matter A is not detected, and when the foreign matter A is detected, the voltage Va corresponding to the size of the foreign matter A The reason for the change in the vicinity is that the potentiometer 10 rotates about its rotation axis 10A to some extent regardless of the presence or absence of the foreign matter A due to the wrinkles and creases of the banknote 5 or the vibration during transfer. The level determination means 30 is a comparison determination voltage level Vr (Vo <Vo <for determining the output voltage level of the potentiometer 10.
Vr <Va), the output voltage V of the potentiometer 10 is compared with this comparison judgment voltage level Vr, and when the output voltage V of the potentiometer 10 is smaller than the comparison judgment voltage level Vr, the output voltage Vo on the other hand, potentiometer 10
When the output voltage V is higher than the comparison determination voltage level Vr, the output voltage Va is output to the control signal output means 31, respectively. The control signal output means 31 determines the presence of the foreign matter A depending on whether the output voltage input from the level determination means 30 is Vo or Va and outputs a predetermined control signal.

Reference numeral 32 denotes a start switch operation determination means, which determines whether or not the start switch 33 has been operated, and when it determines that the start switch 33 has been turned on, outputs a start switch on signal to the control signal output means 31. .

The control signal output means 31 is a start switch operation determination means.
When the start switch-on signal is received from 32, the bottom plate moving signal is output to the bottom plate moving means 34 for moving the bottom plate 4, and the first feed rollers 7A, 7B and the second feed roller 8 are also provided.
And a feed roller drive control means 36 for controlling the drive of the feed roller drive motor 35 for driving the third feed rollers 13A, 13B.
Then, a bill transfer signal is output.

When the bottom plate moving means 34 receives the bottom plate movement signal from the control signal output means 31, the bottom plate moving means 34 moves the bottom plate 4 in the X1 direction so that the bill insertion portion 1 and the transfer path 6 are communicated with each other. Further, the feed roller drive control means 36 drives the first feed rollers 7A and 7B, the second feed roller 8 and the third feed rollers 13A and 13B when receiving the bill transfer signal from the control signal output means 31, The banknote 5 is transferred downward in the transfer path 6.

When the output signal of the potentiometer 10 changes as the bill 5 is transferred, and the control signal output means 31 determines that the foreign matter A is attached to or mixed with the bill 5, the control signal output means 31 A bill reverse transfer signal is output to the feed roller drive control means 36, and the feed roller drive motor 35, and thus the first feed rollers 7A and 7B, the second feed roller 8 and the third feed rollers 13A and 13B are reversely rotated. Then, the banknotes 5 are transferred upward in the transfer path 6 and sent back into the banknote depositing section 1, and an alarm signal is output to the alarm means 37.
The alarm display section 37A of the alarm means 37 visually displays an alarm indicating that the foreign matter A is mixed, and the alarm sound section 37B outputs an alarm sound.

On the other hand, when the output voltage of the potentiometer 10 is constant at the reference voltage Vo and the contamination of the foreign matter A is not recognized, the control signal output means 31 outputs the bill reverse transfer signal to the feed roller drive control means 36. In addition, the banknote 5 does not output an alarm signal to the alarm means 37, and the bills 5 are fed to the first feed rollers 7A and 7B, the second feed roller 8 and the third feed roller 13.
It is sent into the bill storage unit 17 by A and 13B.

FIG. 5 is a flow chart showing an example of the foreign matter processing operation of the foreign matter processing apparatus according to the embodiment of the present invention, and FIGS. 6 (a), 6 (b) and 6 (c) are explanatory diagrams of the operation.

In FIG. 5, first, start switch operation determining means
By 32, it is determined whether or not the start switch 33 is turned on.

As a result, when it is determined that the start switch 33 is turned on, the start switch operation determination means 32 outputs a start switch on signal to the control signal output means 31. On the other hand, when it is determined that the start switch 33 is not turned on, no signal is output and no operation is performed.

FIG. 6 (a) shows a state in which the start switch 33 is turned on. When the bills 5 have been inserted into the bill insertion portion 1, the movable unit (not shown) is moved rearward, and accordingly. Movable plate 3 and first feed roller 7B
Is moved backward from the retracted position, that is, in the X2 direction, and the bill 5 is held by the first feed rollers 7A and 7B. Since the movable plate 3, the first feed roller 7B, the foreign matter detection roller 9 and the third feed roller 13B are attached to a movable unit (not shown), the foreign matter detection roller 9 and the third feed roller 13B also move backward at the same time. Then, the banknote 5 is positioned at a position corresponding to the thickness of the inserted banknote 5.

The control signal output means 31 is a start switch operation determination means.
When the start switch signal is received from 32, the bottom plate moving signal is output to the bottom plate moving means 34 and the bill transfer signal is output to the feed roller drive control means 36.

When the bottom plate moving means 34 receives the bottom plate moving signal from the control signal output means 31, the bottom plate moving means 34 moves the bottom plate 4 forward, that is, in the X1 direction, and connects the bill insertion portion 1 and the transfer path 6 to each other. Further, the feed roller drive control means 36 has a control signal output means 31.
When the banknote transfer signal is received, the feed roller drive motor 34 is driven, and the banknote 5 is transferred from the banknote insertion unit 1 by the first feed rollers 7A and 7B, the second feed roller 8 and the third feed rollers 13A and 13B. It is sent into the transfer path 6 and further transferred downward in the transfer path 6.

Then, the control signal output means 31 determines the presence or absence of the foreign matter A. That is, the banknote 5 has the foreign matter detection roller 9 and the second
When passing between the feed roller 8 and potentiometer
Whether or not the output voltage V of 10 is higher than the comparison reference voltage level Vr is determined by the level determination means 30, and the foreign matter detection roller 9 moves relative to the potentiometer 10,
When the potentiometer 10 rotates about its rotation axis 10A and the output voltage V of the potentiometer 10 becomes higher than the comparison reference voltage level Vr, the level determination means 30
The output voltage Va is output to the control signal output means 31, the control signal output means 31 determines that the foreign matter A is attached to or mixed with the banknote 5, and outputs a banknote reverse transfer signal to the feed roller drive control means 36. At the same time, an alarm signal is output to the alarm means 37. On the other hand, when the relative position between the foreign matter detection roller 9 and the potentiometer 10 does not change, and therefore the potentiometer 10 does not rotate about its rotation axis 10A, the output voltage V of the potentiometer 10 is the comparison reference voltage level Vr. Since it remains smaller, the level determination means 30
Outputs the output voltage V ₀ to the control signal output means 31, and the control signal output means 31 does not output any signal.

In FIG. 6 (b), the bottom plate 4 is moved in the X1 direction,
The banknotes 5 are transferred from the banknote slot 1 into the transfer path 6 by the first feed rollers 7A and 7B, the second feed roller 8 and the third feed rollers 13A and 13B, and the presence or absence of the foreign matter A is detected by the foreign matter detection roller 9. Is detected.

When the feed roller drive control means 36 receives the bill reverse transfer signal from the control signal output means 31, the feed roller drive motor 36
35 is driven in the reverse direction, the first feeding rollers 7A and 7B, the second feeding roller 8 and the third feeding rollers 13A and 13B are reversely rotated to feed the bills 5 upward in the transfer path 6, and the bill insertion portion. Send back within 1. Further, when the alarm means 37 receives an alarm signal from the control signal output means 31, the alarm display section
An alarm indicating that the foreign material A is mixed in 37A is visually displayed, and an alarm sound is output from the alarm sound section 37B. Thus, when the bill 5 with the foreign matter A attached or mixed therein is sent back into the bill insertion portion 1, the feed roller drive control means 36 stops the feed roller drive motor 35, and the bottom plate moving means 34 removes the bottom plate 4.
After being moved in the X2 direction, the banknote 5 is placed on the bottom plate 4.
This state is shown in FIG. 6 (c). When the banknote 5 is placed on the bottom plate 4, the movable plate 3 and the first feed roller
7B is moved to the retracted position to the front side, the shutter (not shown) is opened, and the banknote 5 with the foreign matter A attached or mixed therein is taken out from the banknote deposit machine by the operator or the administrator of the banknote deposit machine. Here, since the vertical distance between the foreign matter detection roller 9 and the bill insertion slot 1 is constant, the time from when the foreign matter detection roller 9 detects the foreign matter A to when the bill 5 is sent back to the bill insertion slot 1 is: Since the feeding speeds of the first feeding rollers 7A and 7B, the second feeding roller 8 and the third feeding rollers 13A and 13B are constant, the feeding roller drive control means 36 controls the feeding roller drive control means 36 after a lapse of a predetermined time after detecting the foreign matter A. If it is set in advance so that the feed roller drive motor 35 is stopped, the bottom plate 4 is moved by the bottom plate moving means 34, the movable plate 3 and the first feed roller 7B are retracted, and the shutter is opened, as described above. The banknote 5 to which the foreign matter A is attached or mixed can be easily taken out from the banknote deposit machine.

On the other hand, when the control signal output means 31 does not determine that the foreign matter A is attached to or mixed in the banknote 5, the banknote 5 has the first feeding rollers 7A and 7B, the second feeding roller 8 and the third feeding roller 13A. , 13B, is transferred downward in the transfer path 6,
It is sent to the bill storage unit 17. The banknote 5 is a banknote storage unit 17
When it is sent inside, the movable holding plate 14 moves forward,
Hold the bill 5 between the fixed holding plate 15 and the kick roller 18,
The bill 5 is fed by the feeding roller 19 and the separating roller 20.
Are fed from the bill storage unit 17 one by one into the bill depositing machine. Whether or not the bill 5 is fed into the bill storage unit 17 depends on the time from the start of feeding operation of the bill 5 by the first feed rollers 7A and 7B, that is, whether the bill 5 is fed into the bill storage unit 17. It is set in advance so that it is determined whether or not a predetermined time required has passed, and the movable holding plate 14 moves at that time.

According to the present embodiment, the foreign material A is detected based on the change in the relative position of the foreign material detection roller 9 with respect to the potentiometer 10 due to the passage of the foreign material A. Therefore, the foreign material A is made of a metal such as a clip or a pin. Of course, even if it is a non-metal object such as plastic, or if the foreign matter A is attached to the banknote 5, it can be detected reliably, and When the foreign matter A is attached or mixed, the bill 5 is always sent back to the bill insertion unit 1. Therefore, the bill 5 with the foreign matter A attached or mixed can be easily taken out from the bill depositing machine. Therefore, it is possible to prevent the banknote 5 from being jammed in the feeding mechanism of the banknote depositing machine due to the foreign substance A or the foreign substance A from damaging the feeding mechanism in advance and reliably.
