The supply unit 200 is operated by the driving unit 300, and the supply unit 200 transfers banknotes and releases them to the outside through the banknote outlet 11.

The control unit, the banknote detection sensor for detecting the presence of the banknotes located on the conveyance path of the banknotes; An encoder sensor 400 for converting an on / off value into an electrical signal according to a slit rotation of the encoder pulley gear 320; And a control circuit that receives the signals from the banknote detecting sensor and the encoder sensor 400 and controls the driver 300.

The banknote detecting sensor is installed on a path through which banknotes are transferred to detect the presence or absence of banknotes, and sends a signal to the control circuit to confirm whether the banknotes are discharged correctly.

The banknote detecting sensor includes a light emitting unit (not shown) and a light receiving unit (not shown). The light emitting unit continuously transmits light to the light receiving unit, converts the light into an electrical signal, and sends the light to the control circuit to release the bill. To be detected.

That is, before the banknote passes between the light-receiving part and the light-emitting part of the bill sensor, in the state where the light of the light-emitting part reaches the light-receiving part, the light-receiving part usually reads a value of about 7-8, and the bill is read by the bill sensor. While entering and passing between the light receiving unit and the light emitting unit, a value of about 30 is read. In addition, after passing through the bill and the bill detection sensor completely, the value of about 7 to 8 is read again, and the value is converted into an electrical signal and sent to the control circuit.

The encoder sensor 400 is connected to one side of the driving motor 310 so that the slit of the encoder pulley gear 320 is turned on and off by rotation.

The encoder sensor 400 has a light emitting unit and a light receiving unit, like the banknote sensor, and a slit portion of the encoder pulley gear 320 is positioned between the light emitting unit and the light receiving unit. Therefore, the encoder pulley 320 is rotated by a drive motor 310, and the encoder sensor 400 is repeatedly turned on and off, and the on-off signal is converted into an electrical signal and sent to a control circuit to the encoder pulley gear. Count the number of slits (320).

The control circuit receives a signal from the banknote sensor and receives an on / off signal of the encoder sensor 400 when the value detected by the light receiving unit of the banknote sensor is changed due to the entry of the banknote of the encoder pulley gear 320. When the number of slits starts counting, when the value detected by the light receiving unit of the banknote sensor changes back to the original value, the counting of the slit is stopped by receiving a signal from the banknote sensor.

Normally, the control circuit counts about 200 slits until one bill passes through the bill sensor and is completely out, which is the length of one bill. The length of one bill is stored in the control circuit at an arbitrary value so that if the number of slits is too small or larger than 200, the bill is not regarded as the length of a normal bill. At this time, an error message is sent to stop the operation of the eastern part 300.

In addition, when two bills overlap and enter the bill detection sensor, the value of the light receiving unit reads a value of about 100, which is different from the value stored in the control circuit, so that it is not recognized as a normal bill and an error message is sent out. ) Is stopped.

The present invention may further include a display unit for displaying the emission bills. When the banknote detecting sensor confirms the entry of the banknote, the signal is sent to the control circuit, and the display unit 410 is counted in units of 1 on the display unit 410 to indicate the number of bills to be released.

In addition, the display unit 410 is exposed to the outside through the opening 12 of the main body frame 10 so that the user can check the number of bills released.

Referring to Figure 8 describes the control method of the banknote supply device according to the present invention. Figure 8 is a flow chart of the operation of the bill supply apparatus according to the present invention.

As shown in Fig. 8, the present invention checks whether the operation is ready for banknote supply, and when an input signal is input, the driving unit is driven by a control circuit to release banknotes, and checks whether banknotes are correctly released and waits. Return to state.

In the operation preparation checking step, when the power is supplied, the banknote detecting sensor checks whether the banknote is jammed on the banknote transfer path, and if it is confirmed that no banknote is jammed, it sends a signal to the control circuit to stand by in the ready state for operation. Is done.

In the driving step, when the start button is pressed or an external input signal is input in the standby state, the driving unit 300 is operated by the control circuit, and the supply unit 200 is driven by the driving unit 300 from the storage unit 100. Transports and releases it to the outside, the banknote sensor detects whether the banknotes detected along the banknote transfer path, the banknote sensor sends a detection signal to the control circuit, the control circuit signal from the banknotes sensor When receiving the input signal to the encoder sensor 400 to sense the on-off signal by the slit of the encoder pulley gear 320, the control circuit receives the signal detected by the encoder sensor 400, the encoder pulley gear Start counting the number of slits 320.

In the bill release confirmation step, if a bill passes completely through the bill detection sensor, the bill detection sensor reconfirms whether the bill is detected, and if the bill detection sensor checks whether the bill is released, the sensing signal is sent to the control circuit and the encoder pulley gear. When the number of slit counting stops at 320 and the banknote detecting sensor confirms that the banknote is completed, the sensing signal is sent to a control circuit, and the operation of the driving motor 310 is stopped by the control circuit. It is made to return to the standby state.

When power is supplied to the bill supplying apparatus of the present invention, the bill detection sensor first checks whether a bill is caught on a path in which the bill is transported in order to check whether there is an operation error.

At this time, if it is confirmed that there is a banknote hanging on the banknote transfer path, by sending a signal to the control circuit to instruct the display unit 410 to display an error, the operation is disabled, the user error of the display unit 410 After confirming the mark, the bill is removed.

However, if there are no bills hanging on the bill transfer path, there is a waiting state to start operation at any time.

When the user presses an operation start button to receive its own input signal or is connected to an external device and receives an external input signal, the driving unit 300 is driven by the control circuit.

When the driving unit 300 is driven, the supply unit 200 is operated by the driving unit 300, and the supply unit 200 extracts bills from the accommodating unit 100 and transfers the bank notes along the transport path.

The banknote is passed along the transfer path and passes through the banknote detection sensor located at a predetermined portion of the transfer path, and the banknote detection sensor sends a sensed signal to the control circuit when the banknote passes through the lower portion thereof.

Here, when the value read from the light receiving unit of the banknote sensor changes to a predetermined value or more, the banknote sensor converts the value into an electrical signal and sends it to the control circuit, and the control circuit instructs the display unit 410 to "1" units. Count the value of. In addition, if the bill does not pass through the bill sensor, it sends a signal to the control circuit to stop the driving unit 300 operation.

The number counted on the display unit 410 becomes the number of discharged bills so that the user can check it, and the operation of the driving unit 300 stops unnecessary driving of the driving unit 300 when there is no loaded banknote and needs to be replenished. To get rid of it.

In addition, the bill detection sensor sends a signal confirming the entry of the bill to the control circuit so that the control circuit detects the signal on and off by the slit rotation of the encoder pulley gear 320 to the encoder sensor 400, the encoder The signal sensed by the sensor 400 is sent back to the control circuit to count the number of slits of the encoder pulley gear 320.

Next, after the banknote passes through the banknote sensor completely, the banknote sensor detects the original value read before the banknote enters, and sends a signal to the control circuit to count the number of slits of the encoder loosening gear 320. To stop the drive unit 300 to stop the operation. In addition, if the bill is still detected at the time of completion of discharge, which is a problem such as another bill is hanging on the transport path, so that the user can determine the problem by sending a signal to the control circuit to display an error message on the display unit 410 To help.

The present invention can be used anywhere that can release a certain number of bills. For example, when a bank connects with a computer terminal and gives an input signal as many as the customer wants, the bill supply device receives this signal and emits a certain number of copies as the user wants.

In addition, the bill supply device of the present invention can be applied to a device for supplying a paper feeder, such as a gift certificate or a lottery ticket having a similar function as a bill and a wide range of applications.

The present invention described above is not limited to the above-described embodiment and the accompanying drawings, and various substitutions, modifications, and changes are possible within the scope without departing from the technical spirit of the present invention. It will be evident to those who have knowledge of.

As described above, the present invention includes a drive unit and a control unit which are driven independently without power supply from an external device to emit a desired number of bills, and can directly check the number of discharges by the display unit. Banknotes can be released only by the input signal of an external device, so it can be applied to any device that can command banknotes.
