Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a money counting machine that counts coins or banknotes while being transferred by a transfer mechanism, and stops the transfer mechanism to stop counting when the number of coins or bills counted reaches a set number. .

Conventionally, as this type of money counting machine, for example, Japanese Patent Application Laid-Open No. 51-1
Invention described in Publication No. 34697 (name: coin counting device)
There is.

According to this invention, when the number of coins to be transferred and discharged reaches a set number, the power transmission mechanism is stopped to stop the transfer of coins,
Counting is now stopped.

The stop mechanism that stops the transfer of coins consists of a solenoid, a stopper, etc. When the set number of coins is reached, the solenoid is energized, and the solenoid operates the stopper.
The coins being transferred are directly blocked to prevent them from being sent to the counter.

By the way, a solenoid generally requires at least 20 m5eOJJ from being energized to operating.

For this reason, when counting at high speed with the above-mentioned conventional device, there is a risk that several coins will be transferred to the counter during this 2077ISeC period when the stopper is activated, and therefore more coins than the set number will be counted.

Therefore, a state of miscount occurs and the counting must be repeated.

The only way to ensure reliable counting is to slow down the coin transfer speed, but if the transfer speed is slow, the counting speed will also be slow.
Counting dozens of coins at once is time consuming and inefficient.

This invention was made in consideration of the above circumstances, and its purpose is to transfer coins to the counter at high speed until the number of coins to be counted approaches the set number, and then at a low speed when the number of coins approaches the set number. To provide a money counting machine which can increase the counting speed to improve efficiency and also enable accurate counting, which is realized by a particularly simple control circuit.

Hereinafter, an embodiment in which the present invention is applied to a coin counting machine will be described with reference to the drawings.

First, the transfer mechanism and counting mechanism of the coin counting machine will be explained with reference to FIG.

First, to explain the transfer mechanism in this invention, 1 in the figure.
1 is a rotary disk having a disk shape and installed so that its surface is vertical, and this rotary disk 1 is a hopper (not shown).

), and the rotary disk 1 is surrounded by a suitable drive device (not shown).

) and rotated.

The coins 4 in the rotary disk 1 are biased toward the outer periphery of the rotary disk 1 by centrifugal force, received by a guide 3 provided on the outside of the outer periphery, and then guided into the passage 3a.

The passage 3a is partitioned in its thickness direction by the flat plate 6 and the running surface of the coin transfer belt 7, and the regulating plate 10 is moved from side to side via the sliding rod 11, and a rail portion fixed to this regulating plate 10 is formed. The distance between the rail portion 9 and the opposing rail portion 8 provided opposite thereto can be adjusted by changing the width of the denomination.

Above the flat plate 6 of the passage 3a, a pair of rollers 5a and sb are provided at both ends along the longitudinal direction of the flat plate 6, and one end of the coin transfer belt 7 wound around the rollers is passed from the rotary disk 1 to the passage. 3a, and is located on the entrance side of passage 3 from rotary disk 1.
The coins sent to the entrance side of a are held between the belt 7 and the flat plate 6, and are sequentially transferred while being pressed against a reference surface formed on the side surface of one rail section 8.
During transportation, the coins fall into a predetermined sorting groove (not shown) formed according to the size of the coin and are selected.

Reference numeral 11 in the figure is a photoelectric coin detector, and a lamp 13 and a phototransistor (not shown) are mounted on a support frame 12 fixed to the machine body, with a lamp 13 and a phototransistor (not shown) facing each other above and below with a passage 3a in between.

When the coin 4 is transferred to the coin detector 11, the coin 4
blocks the light from the lamp 13, so that the detection signal (count pulse) of the phototransistor disappears, and the passage of the coin 4 is detected.

Next, the circuit configuration of the control circuit applied to the present invention will be explained with reference to FIG.

The other end of the start switch SW1, which has one end connected to a power supply (+5V) and the other end grounded via a resistor R1, is connected to a set input end of an SR type flip-flop FFI.

The other end of the stop switch SW2, which has one end connected to the power source and the other end grounded via a resistor R2, is connected to the O
The output terminal of the R gate 30 and the flip-flop FFI (hereinafter abbreviated as FF1) are passed through the OR gate 20.

Other flip-flop FF2. The same applies to FF3.

) is connected to the reset input terminal R of the

The set output signal of FF1 is called a start signal STA, and this signal is sent to the above-mentioned drive device to start this first drive device and cause the coin transfer vernier to run.

The start signal STA is held until the stop switch SW2 is turned on or a stop device drive signal SSD, which will be described later, is output, and the counting operation continues.

The other end of the clear switch SW3, which has one end connected to the power source and the other end grounded via a resistor R3, is a monostable multipipe lake MM3 (hereinafter abbreviated as MM3).

The same applies to the other monomulti MMLMM2), and is connected to the four-digit counter 23 and the reset input terminal R of the SR type rough flip-flop FF2 via the OR gate 21.

The counter 23 internally has an oscillator for latch dynamic lighting and four decimal counters.

And counting pulse input terminal C, digit select terminal 1
0°, 101, 102, and 103, and further has BCD output ends of 2°, 21, 22, and 23.

The above digit select terminal 1 is set by the operation of the internal oscillator.
Pulse signals with equal duty ratios from 0° to 103 are constantly and periodically outputted at the timing shown in FIG.

For example, when a pulse signal of 1'' level is output from the digit select terminal 103, the BCD output terminal 2°~
The content of the output from 23 is configured to represent the content of 103 digits.

Digit select terminal 101 of counter 23 and BC
D output terminal 2° is connected to the input terminal of AND gate 22,
Further, the output terminal of this AND gate 22 is connected to the set input terminal S of FF2, the reset output of FF2 and the set output of FF1 are both input to the AND gate 26, and the output of this A'ND gate 26 is the deceleration signal SPD. It is called,
1 drive device to decelerate the coin transport belt 7.

Further, the reset output of FF2 is input to monostape multi-by-break MM1, and the output of this MMI is input to AND gate 27 together with the set output of FFI.

The output of the AND gate 27 is called a brake signal BR, which is generated at the same time as the deceleration signal SPD and is maintained for a short period of time.The output of the AND gate 27 is called a brake signal BR, which is generated at the same time as the deceleration signal SPD, and is maintained for a short period of time, applying a brake to the drive device to rapidly decelerate it, and then eventually stopping it, completing the counting operation. It looks like this.

BCD output terminal 2° of counter 23 ・21 ・22
・23 is the selected terminal “1000” of the number setting switch 32, each consisting of a rotary switch. ・[200
0J・r4000J・“Connected to 8000J.

Also, BCD output ends 2° and 22 are both AND gate 2.
The output terminal of this AND gate is connected to the selected terminal r5000j.

A common terminal of the number setting switch 32 is grounded via a resistor R4 and also connected to the first input terminal of the AND gate 29.

The second input terminal of the AND gate 29 is connected to the digit select terminal 103 of the counter 23, and the output terminal of the AND gate 29 is connected to the set input terminal S of the SR type rough flip-flop FF3.

A monostable multi-by-break MM is connected to the reset input terminal R of FF3.

2 and the output signal of clear switch SW3 are inputted via OR gate 30.

The set output of FF3 is AN along with the set output of FF2.
The signal is input to a D gate 31, and the output of this AND gate 31 is used as an input signal of MM2.

Further, the set output of FF3 serves as an input signal of MM3.

At the beginning of the counting operation, a pulse is output from the internal oscillator to the counter 23 (in this case, the pulse is output from the digit select terminal 1
In order to input and count 10 pulse signals (pulse signal output from 01), the digit select terminal 101 of the counter 23, the reset output terminal Q of FF2, and the reset output terminal Q of FF3 are both connected to the input terminal of the AND gate 25. The output terminal of the AND gate 25 is connected to the counting pulse input terminal C of the counter 23 via the OR gate 24.

Further, the actual counting pulse outputted from the coin detector 11 is inputted to the input terminal C via the OR gate 24 and counted.

Note that the above-mentioned MM1, MM2, and MM3 output signals for a period equal to the time constant determined by the values of the resistors and capacitors contained therein (see FIG. 3).

Next, the operation of the above embodiment will be explained with reference to FIG.

Now, assume that a coin counting operation is performed in units of 1000 coins.

Therefore, the set number of sheets is 1000, and the number setting switch 32 is set to the terminal r1000J.

A large number of coins 4 to be counted are placed in the hopper of the rotary disk 1.

Also, press clear switch SW3 once to clear FF2 and F.
F3 is reset and the counter 23 is also cleared.

Therefore, the reset outputs of FF2 and FF3 are both lT
141. Moreover, since the internal oscillator of the counter 23 operates and the digit select terminal 101 outputs a 1'' pulse signal periodically, the AND gate 25 outputs a 1'' pulse signal. This pulse signal is applied to the counting pulse input terminal C of the counter 23 via the OR gate 24.

Therefore, the counter 23 counts the pulse signals, and when the count value of the counter 23 reaches "10" (that is, the output of the target select terminal 101 and the output of the BCD output terminal 2° are both 1"). ), AND
Since the gate 22 is opened and FF2 is set, the count value of the counter 23 becomes "10" before starting the counting operation.

Next, when the start switch SW1 is pressed, FF1 is set by its output, and a start signal STA is generated.
The drive device is started by this signal STA, and the transfer belt 7
A transfer counting operation is started in which the coins 4 are transferred one by one to the coin detector 11.

Therefore, the counter 23 is set to the initially set count value "10".
” begins to change.

The drive also operates at a high speed and therefore takes place at high counting speeds.

The 990th coin 4 is detected by the coin detector 11,
When the count value of the counter 23 becomes "1000", the digit select terminal 103 of the counter 23 becomes "1" level and at the same time, the BCD output terminal 2° becomes tl 111, so the output of the AND gate 29 becomes "1". , FF3 is set by this output, and its set output becomes 1''.

This FF3 set output "1" is an AND game with MM3.
Since the counter 23 is input to the counter 31, a pulse of signal "1" is generated from the MM3, and the counter 23 is cleared to "0" by this pulse, and at the same time, the counter 23 is reset than the FF2.

At this time, the output of AND31 remains "0" and does not change.

The AND gate 26 is activated by the reset output “1” of FF2.
The outputs of and 27 both become "1", a deceleration signal SPD and a brake signal BR are generated, and the drive device is braked for a short period of time to rapidly decelerate.

Therefore, the remaining 10 coins are counted at a slow speed.

The counter 23 starts counting again from the 991st sheet, and 10
When the 00th sheet is counted, the counted value becomes "10".

At this time, as described above, select the digit select terminal 1.
The output of 01 becomes "1", and the BCD output end 2° becomes 1.
'', so the output of AND gate 22 becomes 1'',
FF2 is set by this output.

Therefore, the deceleration signal SPD disappears, and at the same time the output of AND gate 31 becomes "1", so the output of MM2 also becomes "1".
1'', this signal is sent to the reset input terminal of FF1 via OR gates 30 and 20, and this FF1 is reset.

Therefore, the start signal STA also disappears at the same time as the deceleration signal SPD, and the counting operation is completed.

However, a coin stopper is provided on the front side of the coin detector 11 in the above embodiment, and is driven at the same time as the start signal disappears.
It is also possible to further improve the system so that coins exceeding the set number are not counted excessively.

Moreover, the present invention can of course be applied to a banknote counting machine that feeds out and counts banknotes one by one, and a banknote counting machine that counts banknotes while they are bundled.

Currency such as coins or banknotes is counted while being transferred by a transfer mechanism, and when the counted number reaches a value smaller than a set number by a second set number, the transfer mechanism is decelerated and then the counted number matches the set number. Then, in the money counting machine which stops the transfer mechanism and finishes counting, a counter is set when the counted value of the counter matches the second set number of coins, and when the counted value matches the set number of coins, the counter is set. a first flip-flop to be reset;
a second flip-flop that is set when the counted value of the counter matches the set number of sheets, and that is reset on condition that the counted value of the counter is cleared at the time of this setting and that the first flip-flop is set; , the above-mentioned No. 1. When both the second flip-flops are in the reset state, the first circuit supplies an oscillation pulse to the counting pulse input terminal of the counter, and when counting coins, supplies the counting pulse of this coin to the counting pulse input terminal of the counter. ,
When a counting start operation is performed, a start signal is output to drive the transfer mechanism at high speed, and when the first flip-flop is reset in this state, braking is applied to the transfer mechanism for a certain period of time to switch to deceleration drive. Said 1st. Since the configuration includes a control circuit each having a second circuit that stops the transfer mechanism when the second flip-flops are set together, when the set number of sheets is n and the second set number is a, As before, n and (na
) is not necessary, and n and a
It is only necessary to provide an extremely simple circuit to determine the value of the coin, and therefore, a money counter capable of extremely high-speed and accurate counting can be realized with an extremely simple and inexpensive circuit configuration. This makes it possible to improve efficiency, economy, and reliability.
