Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a device for sorting the authenticity of all kinds of different coins rolling in the same coin path, which prevents the continuous insertion of coins and allows sorting of sorted coins and sorting of all kinds of coins. The present invention relates to a coin control device for a coin sorting device for reliable operation.

Conventional coin sorting devices include mechanical devices, but
This device had many moving parts and was limited in terms of accuracy and lifespan.

For this reason, electronic devices, which are superior to mechanical devices in terms of accuracy and longevity, are being put into practical use. As a sorting means for such a device, a sorting coil as a detector is placed close to the coin passage, this sorting coil and a standard coil constitute a bridge circuit, and the equilibrium point of the bridge circuit is detected when a coin passes. The means includes an oscillating coil and a receiving coil as a sorting coil, a sorting means for detecting a change in the voltage induced in the receiving coil, and an oscillator using the sorting coil as a resonant element, and detects a change in the oscillation frequency when a coin passes. A screening means for detecting is known. In order to reduce the price, this type of device is configured to use one sorting coil to sort all kinds of coins, so there is only one path for input coins to pass through the sorting coil section. It is. The coins coming out of the passage must be sorted in various directions depending on the sorting state of the sorting means. In other words, there is a need for a gate to sort genuine coins and counterfeit coins, and a gate to sort genuine coins by denomination. Become. The former gate is arranged so that it can appear and appear in the passage, and protrudes into the passage to prevent coins from falling and guides counterfeit coins to the return passage, exits from the passage and lets the coins fall, and guides genuine coins to the genuine coin passage. The latter gate is similarly arranged so that it can appear and appear in the passageway, sorting the coins inserted according to their denominations, and guiding the coins to the change cylinders for each denomination. However, if the gate is simply controlled according to the sorting state, a serious problem will arise if coins are continuously inserted at extremely short intervals. If the gate that separates genuine coins and counterfeit coins is always protruding into the coin passage, and if genuine coins are configured to exit from the coin passage for a certain period of time in response to a sorting signal, then, for example, if a gate is used for mischief, etc. Therefore, when the coins that are successively inserted are genuine coins and counterfeit coins, and a counterfeit coin is inserted following a genuine coin, when the gate that distributes the genuine coins inserted first has left the passage, the next A coin inserted into the gate will pass through the gate.

Therefore, the counterfeit coins are guided into the genuine currency passageway following the genuine coins, and if the diameter of the fake coins is larger than that of the genuine coins, the counterfeit coins clog the genuine currency passageway, making further operation impossible. If the counterfeit coin has the same diameter as the genuine coin or a smaller diameter, there is a drawback that the counterfeit coin will be stored in the change cylinder. Even if the coins that are continuously inserted are genuine coins, if coins of different denominations are inserted, a gate that sorts out the coins that were inserted first will be used. Next, the inserted coins are sorted out, and as described above, there is a drawback that jams occur or coins of different denominations are stored in the change cylinder. In addition, when controlling the gate that sorts the coins guided into the genuine coin passage by denomination, the authenticity of the coins inserted is checked. It is also known that the denomination is controlled by an output signal from a sorting means for sorting denominations, and this is designed to control the appearance and retraction of the gate for a predetermined period of time from the time when the output from the sorting means is generated.

For example, the gate is controlled to protrude into or exit from the genuine coin passage for a certain period of time based on the denomination-specific signal detected by the sorting means. However, the rolling of coins is not always at a constant speed, and the rolling time varies depending on various other factors, such as a dirty coin having a slower rolling time. Therefore, when controlling the gate by time, the control time is Depending on the determination method, it is difficult to reliably sort specie coins by denomination. If it is difficult to sort by denomination in this way, it will not be possible to automatically replenish coins that can be used as change out of the coins inserted into the change tube, resulting in a shortage of change coins and fewer sales opportunities at vending machines. There are drawbacks. Therefore, the present invention eliminates such drawbacks of the conventional device, and ensures that genuine coins among the input coins are sent to the genuine coin passage, counterfeit coins are routed to the return passage, and coins guided to the genuine coin passage are reliably routed to passages according to their denominations. The objective is to provide a device that can allocate

Next, one embodiment of the present invention will be described in detail based on the drawings.

1 and 2 show one embodiment of the invention. In Fig. 1, 1 is the main body of the coin sorting machine, 2 is a coin slot, 3 is a linear protrusion forming a coin passage communicating with the coin slot 2, and 4 is an inspection of the properties of coins rolling through the coin passage. 5 is a first gate for sorting genuine coins and counterfeit coins that can appear in the coin passage; 6 is a second gate for sorting denominations that can appear in the coin passage; 7, 8; 9 is 10 each
Yen, 50 yen, and 100 yen coin storage tubes; 71 and 81 are sorting windows for 10 yen and 50 yen coins; SWl, SW2, and SW3 are the first, second, and third detectors that detect coins, respectively; dotted arrows A and B indicate the directions in which the coins sorted by the first gate 5 are led, A indicates the genuine coin passage direction, and B indicates the return passage direction.

The first, second and third detectors are comprised of, for example, a light emitting diode and a phototransistor. The coins inserted from the coin slot 2 roll on the linear protrusion 3, pass the first detector SWl, the second detector SW2 of the sorting coil, and then, depending on the sorting state, e.g. If the inserted coin is a genuine coin, the first gate 5 exits the passage, and if it is a counterfeit coin, the first gate 5 protrudes into the passage, leading to the genuine coin passage direction as shown by the dotted line. A or return path direction B. And the coin guided in direction A is the third
When the detector SW3 is reached, the second gate 6 is activated depending on the denomination.
Sorted by.

According to the present invention, continuous insertion of coins is detected by the first and second detectors SWl and SW2, and the first coin inserted is the first coin inserted.
The first gate 5 is made to protrude into the passage when the next inserted coin reaches the first detector SWl before passing through the second detector SWl and reaching the second detector SW2. .
As a result, coins that are continuously inserted and roll at a predetermined interval or less are prevented from falling into the genuine coin passage by the first gate 5 and are returned. Further, when the coin reaches the second detector SW2, the appearance and retraction state of the first gate 5 is controlled. Also, the first and second
The detectors SWl and SW2 sandwich the sorting coil 4 and are arranged before and after the coin passage, so that the first
, the second detectors SW1, SW2 can also be used to determine the coin sorting period by the sorting coil 4. That is,
In the sorting means for sorting coins using a bridge circuit with the sorting coil 4 as one side and including standard impedance, the bridge is configured so that the bridge is balanced when the genuine coin passes the position of the sorting coil 4. In the case of a counterfeit coin made of the same material as the real coin and having a larger diameter than the genuine coin, the bridge is balanced when the counterfeit coin enters the area of the sorting coil 4 and when it passes the position of the sorting coil 4. Therefore, it is advantageous when the bridge balance appears only once within the sorting period to be sorted as specie. The second gate 6, which distributes specie coins according to denomination, is controlled when a coin reaches the position of the third detector SW3.
In the case of 0 yen and 50 yen, the second gate 6 protrudes above the passage, and in the case of 100F1:], the second gate 6 exits from the passage.

The 10 yen and 50 yen sorted by the second gate 6 roll in the direction of arrow C, the 50 yen passes through the sorting window 81 and falls and is stored in the storage cylinder 8, and the 10 yen passes through the sorting window 81. 71 and falls and is stored in the storage window 7. Furthermore, since the 100 yen distributed by the second gate 6 is not prevented from falling, it falls as it is and is stored in the storage cylinder 9. Next, use Figures 2 and 3 to prevent continuous injection. Stop,
Gate control will be explained.

FIG. 2 shows a gate control circuit that controls the appearance and retraction of the first and second gates 5 and 6. In the figure, SWll, SW2l,
SW3l is the first, second, and third detector SWl, respectively.
SW2, SW3 detection signal input terminals, 10, 50, 1
00 is the input terminal for the selection signals of 10 yen, 50 yen, and 100 yen, respectively, FFl is the J-K flip-flop circuit, and FF
2 to FF6 are R-S flip-flops (hereinafter simply referred to as FF1).
~FF6), ADl~AD7 are AND circuits (hereinafter simply referred to as .ADl~AD7), 0R1~0R2 are OR circuits (hereinafter simply referred to as 0R1, 0R2), C is a capacitor, Gl, G2 are first and second A gate signal output terminal for transmitting a gate signal for controlling gates 5 and 6 is shown. When the first detector SWl detects an inserted coin, FFl is set via the terminal SWll, and the second
The inserted coin is detected by the detector SW2 and FFL
If a detection signal representing the next inserted coin is given from the terminal SWll before the next input coin is set, FF2 is set so as to memorize that the input coins are consecutive.

That is, if the next inserted coin reaches the first detector SWl before the first one of the continuously inserted coins passes through the first detector SWl and reaches the second detector SW2, FF2 is set. When the coin detection signal from the first detector SW2 is applied to the clear detector C of the FF through the detector SW2l, the FF1 is reset, which causes an extremely short period due to the capacitor C connected to the O terminal of the FF1. After a time delay, FF2 and FF3 are reset. The short delay of the reset input to FF2 ensures that FF2 is set and then subsequently set when the sense signal is applied to terminal SW2l subsequently to terminal SWll at almost the same time.

The FF3 receives a sorting signal indicating genuine coins from a sorting means (not shown) having the aforementioned sorting coil 4 at terminals 10, 50, 1.
It is set by being given from 00.

This FF3 is connected to the first and second detectors SWl,
When set during the sorting period determined by SW2, it is stored that genuine coins have been inserted. In other words, FF3 is set by the detection signal from the first detector SW1, then FF1 is reset by the detection signal from the second detector SW2, and until the reset input is applied to FF3. During the period (sorting period), terminals 10, 50, 1
It is set by applying a selection signal from one of 00 to 00. FF4 is set when FF2 is set and FF3 is set, and a detection signal is applied from terminal SW2l.

This is the case when the inserted coins are separated by a predetermined interval or more and the coins are genuine coins. When FF4 is set, a gate signal is output from terminal G1. On the other hand, the FF4 Nori set is
This is performed when a detection signal is applied from the terminal SW2l when FF2 is set or when FF3 is reset.

That is, the FF4 paste setting is performed when the inserted coins are rolling continuously at a predetermined interval or less, or when a counterfeit coin is inserted. The gate signal outputted from the terminal G1 of the gate control circuit to the first gate 5 causes the first gate 5 to exit from the path when the FF4 is set.
When the gate 4 is set, the first gate 5 is made to protrude into the passage.

FF5 is set when a selection signal is applied from terminal 100, and 0R is applied from either terminal 10 or 50.
A set input is provided by a select signal provided via 2.

Furthermore, FF6 is set when FF5 is set and a detection signal is input from terminal SW3l, and is set when FF5 is reset and a detection signal is applied from terminal SW3l and the AND condition of AD7 is satisfied. It will be done. That is, FF5 is set by being given a sorting signal from terminal 100, and when FF5 is in the set state and the third detector SW3 detects a coin and FF6 is set, a signal is sent from the gate control circuit via terminal G2. A gate signal is transmitted to the second gate 6, causing it to exit the passageway.

On the other hand, when a selection signal appears from either terminal 10 or 50, a reset input is applied to the reset terminal R of the FF5, so that the FF5 is reset. After FF5 has been reset as described above, FF6 is reset when a 10 yen or 50 yen coin is detected by the third detector SW3.

At this time, if the second gate 6 is exiting the passage, the second gate 6 is projected onto the passage.
Therefore, if the inserted coin is 100 yen, the coin will be stored in the storage cylinder 9 without being prevented from falling by the second gate 6, and if the inserted coin is 10 yen or 50 yen, those coins will be stored in the storage cylinder 9. Falling is prevented by the second gate 6 and arrow C
They roll in different directions and are sorted by windows 71 and 81 according to their diameters. Next, the operation will be explained with reference to the waveform diagram shown in FIG.

In FIG. 3, vertically partitioned lines a to f indicate different states. A case will be explained in which the inserted coins are rolling apart from each other by a predetermined interval or more, and the inserted coins are genuine coins and are worth 100 yen.

A waveform diagram at this time is shown in FIG. 3a. In this case, the coin is first detected by the first detector SWl, and a logic signal "1" (hereinafter simply referred to as "1") is applied to FFl via the terminal SWll, and FFl is set. . As a result, a logic signal "o" (hereinafter simply referred to as "0") appears at the η terminal of FFl, so the output of AD2 becomes "
0'', and the reset input signals for FF2 and FF3 are canceled. When the coin reaches the position of the sorting coil 4, it is shown as C in Fig. 3.
When a coin input terminal signal shown by appears at terminal 100 and is applied to FF3 via 0R1, FF3 is set. Next, when the inserted coin is detected by the second detector SW2, FFL is reset via the terminal SW2l. At this time, since "1" is applied from the terminal SW2l to AD3, AD3 sets FF4 because an AND condition is established between the "1" output from the η terminal of FF2 and the "1" output from the Q terminal of FF3. At the same time as FF4 is set, the gate ends C.
1 is outputted from the gate control circuit through the gate control circuit 1, and the first gate 5 shown in FIG. As mentioned above, when FFL is set by the detection signal from the terminal SW2l, "1" is output from the O terminal, and the AND condition of AD2 is satisfied a little later than the coin detection signal from the second detector SW2. ShiFF
A set input is given to FF2 and FF3, and FF3 is set.

Note that FF2 continues to be in the set state.FF3
By setting the value, [1] is input to one input of AD4.
However, since no detection signal is provided via the terminal SW2l at this time, the output of AD4 is "0".

On the other hand, when the selection signal appears at the terminal 100, FF5 is set and "1" is applied from its Q terminal to one input terminal of AD6.

When the inserted coin passes through the first gate 5 exiting the passageway as described above and reaches the position of the third detector SW3, a detection signal is transmitted from the third detector SW3.
This detection signal is applied to the other input terminal of AD6 via terminal SW3l, and since the AND condition of AD6 is satisfied, a set input is applied to FF6.

By setting FF6, gate terminal G2
A gate signal "1" is transmitted from the gate control circuit to the second gate 6 via the gate control circuit, and the second gate 6 exits from the coin passage.

Therefore, the input coins are not prevented from falling by the second gate 6 and fall and are stored in the storage cylinder 9. Next, a case will be explained in which the inserted coins are separated by a predetermined interval or more, but the coins are deposit coins.

A waveform diagram at this time is shown in FIG. 3b. As shown in FIG. 3b, the inserted coin is first detected by the first detector SWl, thereby setting FFl. Next, the inserted coin reaches the position of the sorting coil 4, but since it is a deposit coin, the terminal 10
, 50 and 100 via 0RI to FF3, and FF3 continues in the reset state.

After this, when the second detector SW2 detects a rolling coin, FF1 is reset, and AD4, which takes this detection signal as one input, is in the reset state of FF3, so the AND condition is satisfied and FF4 is reset. Gives a set signal. As a result, FF4 is reset, and the gate control circuit outputs the gate signal 60 through the gate terminal C1. In response to this gate signal, the first gate 5, which had left the passage in the previous sorting operation, projects into the passage, prevents the inserted coins from falling into the genuine coin passage, and distributes them to the return passage. On the other hand, the second gate 6 is F
Since F5 and FF6 continue to be in the set state, they continue to be in the state where they left the passage. Next, coins are continuously inserted and these coins are rolling at intervals less than a predetermined interval, and the first coin inserted is a genuine coin (10 yen) and the next coin inserted is a genuine coin (10 yen). Explains Yanghe, which is a counterfeit currency.

The waveform diagram at this time is shown in FIG. 3c. Similarly to the above, when the first inserted coin is detected by the first detector SWl, FFl is set by the detection signal and FF2 is set.
, FF3 reset input is canceled. When the inserted coin reaches the position of the sorting coil 4, a set input is given to FF3 from the terminal 10 via 0R1, and the input from the terminal 10 to 0R is applied.
A reset input is applied to FF5 via FF2. After that, before the inserted coin reaches the position of the second detector SW2, the next inserted coin reaches the position of the first detector SWl, so the input terminal RL of ADl is connected to one input terminal of ADl via the terminal SWll. is given. At this time, since 11J of the Q terminal of FFl is applied to the other input terminal of ADl, the AND condition is established, FF2 is set, and it is stored in FF2 that the coin is rolling at a predetermined interval or less. When the first inserted coin reaches the position of the second detector SW2 and is detected, r1 is applied to one input terminal of AD5 via the terminal SW2l, and this AD5 has FF2 set. As a result, the AND condition is satisfied and a reset signal is given to FF4. At this time, since the FF 4 has already been reset in the previous sorting operation, it continues in the reset state, and the first gate 5 protrudes into the passage. Of course FF
When 4 is in the set state, FF2 is set and AD5
When the AND condition is satisfied, the FF 4 is reset to cause the first gate 5, which had been exiting the passage, to protrude into the passage. When a detection signal is input from the terminal SW2, the FF
This causes FF2 and FF3 to be reset and enter a standby state. On the other hand, FF5 is in the set state because the selection signal is applied from the terminal 10 as described above, but since no detection signal is output from SW3l, the AD
7 is not satisfied, and FF6 is still in the set state.

As described above, since the first gate 5 protrudes into the passage, the coins continuously inserted are sorted into the return passage. Next, the coins that have been continuously inserted are rolling at less than a predetermined interval,
The case where all of these coins are counterfeit coins will be explained.

A waveform diagram at this time is shown in FIG. 3d. When the first inserted coin is detected by the first detector SWl, FFl is set, and the reset input signals of FF2 and FF3 are thereby released. This coin is then sent to the second detector S.
Since the coins inserted before reaching the position W2 are detected by the first detection rock βW1, FF2 is set via ADl and the continuous insertion is memorized.

Although the first coin inserted passes the position of the sorting coil 4, it is a counterfeit coin, so no sorting signal is input from the terminals 10, 50, and 100. Then, when the first injected curing is detected by the second detector SW2. A reset signal is applied to FF4 via AD5. At this time FF
4 has been set from the previous time, so it continues in that state, and the first gate 5 protrudes into the passage. On the other hand, when a detection signal is applied to FFl via the terminal SW2l as described above, FFl is reset, and then a reset signal is applied to FF2 and FF3 to enter a standby state. Next, a case will be explained in which the inserted coin is a genuine coin (50 yen) and only this coin is inserted. A waveform diagram at this time is shown in FIG. 3e. When the inserted coin is detected by the first detector SWl, FFl is set and the reset input signals of FF2 and FF3 are released. When the inserted coin passes through the first detector SWl and reaches the sorting coil 4, a sorting signal is input to the terminal 50, FF3 is set via 0R1, and a resetting signal is given to FF5 via 0R2.

At this time, since FF has been reset from before, it continues in its reset state. After this, when the inserted coin is detected by the second detector SW2, AD3, which takes this detection signal as one input, has FF2 set and FF3 is set, so the AND condition is satisfied, so FF
Give a set input to 4. As a result, FF4 is set, and the gate control circuit transmits "1" through gate terminal G1, causing first gate 5 to exit from the passage. As mentioned above, when a detection signal is input from terminal SW2l, FFl
The resetting input signal is then applied to FF2 and FF3 to enter a standby state. Second detector S
The inserted coin that has passed the position W2 is guided in the genuine coin passage direction A without being prevented from falling by the first gate 5, and is passed through the third detector SW3. detected.

When the inserted coin is detected by the third detector SW3,
Since FF5 of AD7 is also reset, the AND condition is satisfied and a reset input signal is given to FF6. When FF6 is set, RO appears at its Q terminal and passes through the second gate 6! Make it stand out. As a result, the input coins are prevented from falling by the second gate 6 and are sorted in the direction of arrow C, passing through the sorting window 81 and stored in the storage cylinder 8. Next, three coins are inserted in succession, and the first and second coins are inserted.
A case will be described in which the coin and the second and third coins are respectively rolling at a predetermined interval or less.

A waveform diagram in this case is shown in FIG. 3f. FFl and FF2 are set by the first and second coins that are successively inserted, and then when the first coin reaches the position of the second detector SW3, a reset input is given to FF4 via AD5. . This causes the first gate 5 to protrude into the passageway and return the inserted coins. Then, before the second input coin reaches the position of the second detector SW2, FFL is set again by the third input coin, but the second coin does not reach the position of the second detector SW2. It is reset by As a result, the FF 4 is not changed in any way, so the first gate 5 continues to protrude from the passageway and returns the inserted coins. According to the present invention as described above, it is possible to reliably return continuously inserted coins when they are rolling at a predetermined interval or less. It will not be guided in the direction of the passage and will not become clogged or stored in the storage cylinder.

In addition, the control of the gate for sorting the inserted coins by denomination between genuine coins and counterfeit coins, or genuine coins, is performed while checking the rolling position of the inserted coins, so that the coins can be sorted reliably. The state in which the gate appears in and out of the passageway is not changed every time the input coins are sorted, and it appears and appears as necessary, which has the advantage of suppressing fatigue of the electromagnet used to make the gate appear in and out of the passageway, for example. .
