Description

[Detailed Description of the Invention] (a) Field of Industrial Application The present invention relates to a banknote exchange machine that stores exchange coins in a hopper of a coin feeder and dispenses coins from the hopper at the time of exchange.

(B) Prior art As shown in Japanese Patent Publication No. 53-31759, such a money exchange machine exchanges coins of the same type, which are supplied in a random manner into a hopper, into one coin while arranging them into a predetermined number. It is equipped with a coin feeder that automatically takes out as many coins as you want.

(c) Problems to be Solved by the Invention However, if the clutch mechanism of the payout motor of such a coin feeder malfunctions, the motor will overrun, causing the exchange machine to dispense more coins than the specified number.

Therefore, the present invention provides a banknote exchange machine that can cancel the exchange when extra coins are dispensed.

Furthermore, the present invention relates to a banknote exchange machine that is capable of dispensing all coins in the hopper regardless of the exchange operation when coins are collected.

(d) Means for Solving the Problems The configuration of the present invention will be explained with reference to drawings showing an embodiment.A coin dispensing detector outputs a detection signal by detecting a coin dispensed from the coin feeder 2 through the coin gutter 7. When the switch 5 and the bill validator 1 determine the appropriateness of the inserted bill, they set a predetermined number of coins to be exchanged according to the bill and output a dispensing signal to the coin feeder 2, and the coin dispensing detection switch 5 accompanying the dispensing. The counter 6 is provided with a counter 6 which performs a subtraction operation in response to a detection signal generated from the counter 6 and stops outputting a payout signal when the result reaches substantially "0". Flip-flop circuit 17 as a currency exchange stop control device
is configured to be set when the coin payout detection switch 5 outputs a detection signal while the counter 6 has stopped outputting the payout signal, and the output at this time is introduced to the banknote validator 1 as a change stop signal. ing. The bill validator 1 stops accepting banknotes from the currency exchange machine upon input of this currency exchange stop signal. The inventory switch 14 and the banknote validator 1 are switched in conjunction with the operation of switching the coin gutter 7 to the coin collecting direction, and output a dispensing signal to the coin feeder 2.
and an inventory standby switch 11 that outputs a currency exchange stop signal.

(E) Effect When the coin feeder 2 dispenses more coins than the specified value, a detection signal is generated with the counter 6 substantially in the state of "0", and the flip-flop circuit 17 prohibits the acceptance of banknotes as a machine abnormality. . Then, when the inventory switch 14 is switched, a payout signal is input to the coin feeder 2 to initiate a collection operation, and when the inventory standby switch 11 is switched, the acceptance of banknotes is prohibited as in the case when currency exchange is stopped.

(f) Examples An embodiment of the present invention will be described below in detail based on the drawings.

Reference numeral 1 denotes a bill validator for determining the authenticity of bills, which outputs an "L" level signal in a standby state, and shuts off a bill receiving opening by driving a solenoid, for example, so as not to accept bills in response to an exchange stop signal. Of course, the motor of the identification device may be reversed to return the identification device. Reference numeral 2 denotes a coin feeder for dispensing exchange coins, for example, 100 yen coins one by one, and a dispensing motor 3 dispenses the coins in a hopper 4. A coin dispensing detection switch 5 operates every time a coin is dispensed from the feeder 2, and outputs an "H" level detection signal every time it is detected. 6 is a counter, and when a signal indicating the suitability of accepted banknotes is inputted from the recognition device to the A, B, and E terminals, the counter sets a set value to the number of coins to be exchanged ("10" for a thousand yen bill), and Dispensing motor 3 of coin feeder 2
At the same time, a payout signal of "H" level is issued from the D terminal to make exchange coins be paid out, and when the detection signal from the coin payout detection switch 5, which is activated every time the coin is paid out, is input to the C terminal, it is sequentially subtracted from the set value. The configuration is such that the drive of the motor 3 is stopped when the value reaches "0". Reference numeral 7 denotes a coin gutter which serves as a passage for the coins dispensed from the feeder 2, and its upper end is rotatably supported by a pin 8, and its lower end is usually suspended by a spring 9. , communicates with a dispensing chute 10 that leads coins to an outlet (not shown). When the coin gutter 7 and the payout chute 10 are in communication, the inventory standby switch 11 outputs an "L" level signal. Reference numeral 12 denotes a collection chute that leads to a safe, for example, and when it is necessary to take out all the coins in the hopper 4 at the end of a day's exchange or for inspection or repair, the chute is pulled against the spring 9.
When the operating rod 13 is pressed, the coin gutter 7 rotates about the pin 8 and communicates with the collection chute 12. When the coin gutter 7 rotates clockwise with this collection operation, the inventory standby switch 11 outputs an "H" level operation signal and the inventory switch 14 is activated.
The “H” level inventory signal is the supply device 2
The coins in the hopper 4 are delivered to the payout motor 3, and the coins in the hopper 4 are collected into the safe. 15 is an inverter which inverts the output of the counter 6 and inputs it to the AND gate circuit 16; The gate circuit 16 also receives an "H" level detection signal from the coin payout detection switch 5. The exchange stop control device which outputs a change stop signal when this detection signal is inputted while the counter 6 has stopped outputting the payout signal is constituted by, for example, an RS type flip-flop circuit 17, and the AND gate circuit 16 When the S terminal inputs the “H” level operation signal,
It issues an "H" level set signal and holds its memory until it is reset. Reference numeral 18 denotes an OR gate circuit, and when the coin trough 7 is rotated when collecting coins in the hopper 4, the inventory standby switch 11 is activated, and an "H" level signal is input to the gate circuit 18. The OR gate circuit 18 is also configured to receive the output of an instantaneous reset type reset switch 19 that is operated after checking the coin feeder 2 or turning on the power. When the operating signal of the OR gate circuit 18 is input to the R terminal of the flip-flop 17, the memory retention of the circuit 17 is released and reset.
Reference numeral 20 denotes an OR gate circuit which issues an exchange stop signal to the discriminator 1 when an "H" level set signal from the Q terminal of the flip-flop circuit 17 and an operation signal from the inventory standby switch 11 are input.

The operation of the above configuration will be explained below.

The following explanation will be given assuming that a 1,000 yen bill is to be exchanged into 10 100 yen coins. First, when the bill inserted from the bill insertion slot (not shown) is determined to be "true" by the bill validator 1, "true" signals of "H" level are sent to the A, B, and E terminals of the addition/subtraction counter 6. input. Then, the counter 6 sets the set value to ``10'' as the number of coins to be exchanged, and this setting causes a dispensing signal of the "H" level to be issued from the D terminal, and the dispensing motor 3 of the coin feeder 2 is driven to dispense coins. Start. Further, this payout signal is inverted by the inverter 15 and an "L" level signal is input to the AND gate circuit 16. Then, the coin dispensed detection switch 5 is actuated by the coin dispensed by the drive of the motor 3, and the detection signal of the "H" level generated each time it is operated is inputted to the C terminal of the counter 6, and the coin dispensing detection switch 5 is inputted to the C terminal of the counter 6, and the coin dispensing detection switch 5 is inputted to the C terminal of the counter 6. Subtract "1" from On the other hand, the detection signal at the "H" level is input to the AND gate circuit 16, but since the other input from the inverter 15 is at the "L" level, the output of the flip-flop circuit 17 is at the "L" level. can be,
This does not mean that currency exchange will be cancelled. Eventually the subtraction result becomes “0”
Then, the output of the D terminal of the counter 6 becomes "L" level, the dispensing motor 3 stops, and dispensing stops. Accordingly, the 10 coins to be exchanged are guided from the coin gutter 7 to the outlet via the payout chute 10, and the coins are again in the exchange standby state. After this dispensing, the output of the D terminal of the counter 6 is inverted and an "H" level signal is input to the AND gate circuit 16, but the output of the coin dispensing detection switch 5 becomes "L" level, and the AND gate circuit 16 receives an "H" level signal. The output of remains "L".

Next, if a problem occurs in the clutch mechanism of the payout motor 3 of the coin feeder 2, the motor 3 will overrun and pay out more coins than the specified number.The operation will be described below.

As mentioned above, when a dispensing signal is issued from the D terminal of the counter 6 to the motor 3 of the coin feeder 2 and a coin is dispensed, even if the subtraction result of the counter 6 becomes "0", the dispensing signal of the motor 3 is If more than the specified number of coins are dispensed due to overrun, the input of the AND gate circuit 16 is activated by the coin dispensing detection switch 5.
When the 11th sheet is detected, both become "H" level, and the S terminal of the flip-flop circuit 17 goes "H".
Since the level operation signal is input and set, Q
A currency exchange stop signal is sent from the terminal via the OR gate circuit 20 to the discriminator 1, and the discriminator 1 drives a solenoid (not shown) to refuse acceptance of the banknotes and cancel the exchange. When the manager operates the reset switch 19 after replacing the payout motor 3 of the bill validator 1, the OR gate circuit 1
8, an "H" level signal is input to the R terminal, and the flip-flop circuit 17 is reset.
Therefore, the sending of the exchange stop signal to the banknote validator 1 is stopped, the solenoid is de-energized, the banknotes can be accepted, and the banknotes are in a standby state.

Next, since it is necessary to take out all the coins in the hopper 4 of the feeder 2 at the end of the day's exchange or for inspection/repair, the operation at that time will be described.

First, open the front door of the banknote exchange machine and press the operating lever 13.
is pressed against the spring 9 to rotate the coin gutter 7 about the pin 8 in the coin collecting direction, thereby communicating the gutter 7 with the collecting chute 12. At this time, the inventory standby switch 11 is activated, so the OR gate circuit 20 is activated and an exchange stop signal is sent to the banknote validator 1, and the inventory switch 14 is also activated, and an "H" level inventory signal is sent to the dispensing motor 3. All the coins in the hopper 4 are guided to the collection safe via the collection chute 12 regardless of the exchange operation. At this time, each time the coin dispensing detection switch 5 detects, an "H" level detection signal is input to the AND gate circuit 16, and the operation signal of the gate circuit 16 is input to the S terminal of the flip-flop circuit 17. 11
The operating signal of the gate circuit 18 is input to the OR gate circuit 18, and the operating signal of the gate circuit 18 is input to the flip-flop circuit 1.
7, the flip-flop circuit 17 does not operate because both inputs become "H".

After the coins in the hopper 4 have been collected in this way, when the operating rod 13 is returned to its original position, the coin trough 7 rotates and is returned to its normal standby position by the spring 9.
When the inventory switch 14 returns, the inventory standby switch 11 also returns. Therefore, the dispensing motor 3 stops and the OR gate circuit 2
The exchange stop signal from 0 also stops, cancels the exchange stop, and enters a standby state. In addition, coin gutter 7
If the currency does not return to its normal position, the suspension of exchange will not be lifted.

(G) Effects of the invention According to the invention, in a bill exchange machine, the coin feeder dispenses exchange coins from the hopper when the bill validator determines the authenticity of the bill and determines that the bill is appropriate. If the clutch mechanism of the dispensing motor of the feeder is overrun during currency exchange and the motor overruns and dispenses more than the specified number of coins, the exchange can be stopped and damage can be kept to a minimum. By switching the coin gutter to the coin collecting direction, all the coins in the hopper can be collected regardless of the exchange operation, thereby providing a banknote exchange machine with good operability.
