Description

Motor controller for paper money discernment device

The present invention relates to a banknote takeout motor control device for a banknote identifier, in particular, the control unit is driven on the banknote input side and the banknote output side, respectively, the control unit drives the banknote takeout motor according to the detection signals of the first and second sensors for detecting the progress of the banknotes If the bill is not detected by the first sensor, but the bill is detected by the second sensor, the bill taking motor is reversed to force the bill to be ejected, so that children or other bad people have a transparent tape at the end of the bill. The present invention relates to a banknote ejection motor control device for a banknote identifier that prevents the banknote taking motor from being damaged when a user presses an object selection button and tries to forcibly take out a banknote.

Currently, vending machines for selling cigarettes or beverages are automatically installed in various places, and these vending machines are equipped with a bill identifier for identifying bills put by the user.

The conventional banknote identifier is a sensor for detecting whether the banknotes are inserted, a withdrawal motor for driving the rollers to drive the banknotes to a certain position, and when the banknotes are detected by the sensor, the banknotes are rotated and the banknotes put into the vending machine are sold. It is configured to include a control unit for controlling the transfer to the inside.

When the user pushes the bill into the bill slot of the vending machine, the sensor detects the bill and outputs a predetermined electric signal to the controller, and the controller selects the withdrawal motor when the bill is detected by the sensor. By rotating the rollers to rotate, the inserted banknotes are transferred into the vending machine and transferred to the set standby position.In this case, when the user presses a product selection button provided in the vending machine, the banknotes are completely transferred to the banknote collection machine and the corresponding items and change This will be discharged.

However, the conventional bill identifier is simply configured to rotate the withdrawal motor forward when the bill is detected by the sensor and when the user presses the object selection button while the bill is stopped at the standby position, the bill is transferred toward the inside of the vending machine. Therefore, a child or a person with a bad mind puts the bill at the end of the bill with the transparent tape attached to the end of the bill so that the bill stops at the standby position, and then presses the object selection button and pulls the transparent tape at the same time. When the bill is pulled out, the drawer motor is forced to rotate in reverse, causing the drawer motor to break.

In other words, if a user with a bad purpose inserts a bill into the bill slot with the transparent tape attached to the end of the bill, the bill is transferred to the standby position by the operation of the drawing motor and stopped. If you press the select button, the bills stopped at the standby position will be moved to the bill collection box inside the vending machine, and the selected item and change will be discharged and provided to the user.The user presses the select button and grabs the transparent tape. When pulled, the goods and change are discharged and the banknotes are flowed back by the transparent tape to be discharged again through the banknote opening.

In this process, the withdrawal motor to be rotated forward is forcibly rotated by the banknote flowing back, causing a problem in that it is damaged due to an overload and the banknote identifier itself must be replaced.

Therefore, the present invention for solving the above problems is formed on the banknote input side and the banknote output side, respectively, the control unit drives the banknote taking motor according to the detection signal of the first and second sensors for detecting the progress of the banknote, the first sensor Even though the bill was not detected in the second sensor, when the bill is detected by the second sensor, the bill retracting motor is rotated so that the bill is forcibly ejected, so that children or other bad people have a transparent tape attached to the end of the bill. It is an object of the present invention to provide a banknote withdrawal motor control device for a banknote identifier that prevents the banknote taking motor from being damaged when the article selection button is pressed and the bank is forcibly taken out.

Hereinafter, a preferred embodiment of the present invention with reference to the accompanying drawings, Figures 1 to 3 as follows.

Reference numeral 1 denotes a housing of the banknote identifier mounted inside the vending machine, and a lower guide plate 3 is formed above the housing 1 to guide the entry of the banknote.

The upper side of the lower guide plate 3 is formed such that the cover 4 is rotated to be coupled to the upper side of the housing 1, and the lower side of the cover 4 is opposed to the lower guide plate 3 with a predetermined interval. The upper guide plate 2 is formed.

Under the lower guide plate 3, a motor 7 for withdrawing a bill is formed, and the roller 8 is rotatably coupled to the input side (right side in the drawing) and the output side (left side in the drawing) of the lower guide plate 3. At this time, the roller 8 on the output side is rotatably supported on the rotation shaft of the motor 7, and the belt 9 for conveying the bills is wound on the outer circumferential surface of the roller 8 formed on the input side and the output side.

The belt 9 is installed slightly higher than the surface of the lower guide plate 3, as shown in Figure 2 so as to be able to effectively transport the banknotes entering from the bill slot, the upper guide plate 2, respectively The driven roller 21 which rotates against the roller 8 of this is formed.

First and second through holes 5 and 6 are formed in the upper guide plate 2 and the lower guide plate 3, respectively, so that the first through holes 5 face the input sides of the guide plates 2 and 3, respectively. They are formed in pairs, and the second through holes 6 are formed in pairs so as to face the output sides of the guide plates 2 and 3, respectively.

First and second sensors 10 and 13 are installed in the first through holes 5 and the second through holes 6, respectively, and the first sensor 10 has a banknote insertion slot. The second sensor 13 detects whether or not the bill is entered and transferred to the standby position.

The first sensor 10 and the second sensor 13 are composed of light emitting parts 11 and 14 and light receiving parts 12 and 15, respectively, and when the bill passes through the through holes 5 and 6, the light emitting part. The light irradiated from (11) and (14) is not supplied to the light receiving units 12 and 15 so that each of the light receiving units 12 and 15 outputs a low signal to the control unit 16, and the banknote passes through. (5) When not passing through the light, the light emitted from the light emitting units 11 and 14 is supplied to the light receiving units 12 and 15 so that the light receiving units 12 and 15 are brought to the control unit 16 in a high state. It will output a signal.

On the output side of the upper guide plate 2, a stopper 20 is rotatably installed in the direction in which the banknote proceeds, and the stopper 20 protrudes downward from the upper guide plate 2 as shown in FIG. While the banknote is rotated clockwise by the banknote when the banknote proceeds by the driving of the motor 7, the banknote is present in the standby position, and the banknote moves to the banknote collector as the user presses a product selection button. When it returns to its original position by its elasticity, it outputs a predetermined drive signal to the controller 16.

That is, the article and the change are discharged by the drive signal of the stopper 20.

Reference numeral 16 denotes a control unit for forward and reverse rotation of the motor 7 according to the banknote detection signals of the first and second sensors 10 and 13.

The controller 16 rotates the motor 7 forward from then on when the banknote is detected by the first sensor 10 and the high signal P1 is input, as shown in FIG. The bill is detected by the second sensor 13 while passing through the through hole 6, and the high signal P2 is output from the second sensor 13 as shown in FIG. By outputting a motor drive signal such as P4 in (C), the motor 7 is rotated forward so that the bills are transferred to the standby position.

That is, in the standby position, as the output signal of the second sensor 13 falls to the low state while the tip of the banknote passes through the second through hole 6, the controller 16 turns off the motor 7 so that the banknote is in FIG. Refers to a state existing at the position of B, wherein the motor 7 starts the forward rotation from the first sensor 10 under the control of the control unit 16, and the banknote starts the second hole 6. It will stop at the point where it passes completely.

As described above, when the user inputs the object selection button when the banknote is in the standby position, the controller 16 which detects the input of the object selection button rotates the motor 16 again to move the banknote toward the banknote collection box. At this time, the stopper 20 returns to its original state as the banknote is transferred to the banknote check box, and outputs a driving signal. The control unit 16 receiving the driving signal discharges the object and the change selected by the user. .

Here, the biggest feature of the present invention is to quickly drive the motor (7) in the reverse direction when the bill is detected in the second sensor 13 despite the bill is not detected in the first sensor (10).

In other words, if a person with a bad purpose inserts a bill with a transparent tape attached to the end of the bill and enters the standby position, while pressing the object selection button and simultaneously pulling a transparent tape, the bill is pulled out. The second through hole 6 is again covered while moving to the right side in FIG. 2, whereby a high signal such as P3 in FIG. 3B is output from the second sensor 13.

In this case, although the banknote is not detected from the first sensor 10, the controller 16 quickly detects the banknote from the second sensor 13 to prevent damage to the motor 7. It outputs a reverse rotation signal such as P5.

The motor 7 which receives the reverse rotation signal from the control unit 16 such as P5 rotates in reverse to rotate the roller 8 so that the banknotes are discharged to the bill slot, so that the transparent tape is attached to the end of the banknotes. When forcibly withdraw the banknote by the motor 7 is forcibly reversed by the banknote that is pulled in the reverse direction to prevent overload and damage in advance.

As described above, the present invention is formed on the banknote input side and the banknote output side, respectively, the control unit drives the banknote takeout motor according to the detection signal of the first and second sensors for detecting the progress of the banknote, If bills are detected by the second sensor even though they are not detected, the bill takeout motor is rotated so that the bills are forcibly ejected, so that children or other bad people have a transparent tape attached to the end of the bills. This is a very useful technique that prevents the banknote takeout motor from being broken when forcibly pressing the banknote and forcibly pulling out the banknote.
