Abstract

The coin sorting machine control includes first & second detectors in the coin passage upstream of a coin segregating member and moving the segregating member to its coin return position when a second coin is detected by the first detector (SW1) before the first coin has been detected by the second detector(SW2). The number is controlled by a logic receiving the outputs from the coin detectors and comprising a J-K type flip-flop, R-S type flip-flop, and OR ccts. In the case when inserted coins are spaced less than the predetd. distance from each other, the coins are positively returned.

Description

Control method of coin sorting device

Figure 1 is a front view of the main portion showing an embodiment of the present invention.

2 is a principle circuit diagram.

3 is a waveform diagram.

The present invention is a device for sorting the authenticity of different types of metals that drive the same hardening passages, wherein the hardening screening device is used to prevent continuous input of hardening and to reliably distinguish between sorting and money types. It relates to a curing control method of.

Conventional coin screening apparatuses include mechanical apparatuses, but there are many moving parts in these apparatuses, which have limitations in terms of accuracy and lifetime.

For this reason, electronic devices that are superior to mechanical ones in terms of precision and lifespan are being put to practical use.

As the sorting means of such a device, sorting coils serving as detectors are arranged in the curing passage in close proximity, and the sorting coil and the standard coil form a bridge circuit, and sorting means for detecting the equilibrium point of the bridge circuit when the curing passes. Separating means for detecting the change of oscillation frequency at the time of hardening by providing oscillating coil and receiving coil as a coil, and having a sorting means for detecting a change in voltage induced in the receiving coil and an oscillator having the sorting coil as a resonating element. This is known.

In this type of device, in order to reduce the price, one sorting coil is configured to sort out many kinds of money, so there is only one passage for input curing through the sorting coil.

In addition, the hardening from the passage must be divided in various directions according to the sorting state of the sorting means, that is, a gate for distinguishing between normalization and counterfeit and a gate for sorting by money type in the case of normalization.

The former gate is arranged in the passage, protrudes into the passage, prevents the fall of the coin, guides the counterfeit to the return port, decays in the passage, and drops the coin, leading the normalization to the storage direction. Similarly, it is arranged in the aisle, and the input hardening is classified according to the type of money, and the hardening is guided to the change container for each type of money.

However, in the case of controlling the gate only according to the sorting state, an important problem arises when the curing is continuously applied at extremely short closing intervals.

If the gate separating the normalization and counterfeiting of the input hardening is always protruded into the hardening passage, and in the case of normalization, it is configured to sink in the hardening passage only for a certain time according to the selection signal. When normalization and counterfeiting are respectively followed by counterfeiting following normalization, when the gate separating the initially normalized is depressed in the passage, the next hardening passes through the gate position.

Therefore, after the normalization, the counterfeit is guided in the receiving direction. If the counterfeit is larger than the normalized counterfeit, the counterfeit is blocked in the normalization passage, and further operation is impossible, and the counterfeit is smaller than or equal to the normalized diameter. In the case of diameter, there is a crystal in which forgery is stored in a change container. In the case where the continuous curing is normalized, when different types of money are added, the next added hardening is divided by the gate that distinguishes the first added money, so that clogging occurs or hardening of different types of money as described above. Has the drawback of being housed in a change container.

It is therefore an object of the present invention to provide a control method of curing that can reliably distinguish between curing by eliminating the defects of such a conventional apparatus and eliminating irrational points caused by continuous feeding.

Next, an embodiment of the present invention will be described in detail with reference to the drawings.

1 and 2 show one embodiment of the present invention.

In Fig. 1, reference numeral 1 denotes a coin selector main body, 2 denotes an inlet, 3 denotes a linear protrusion constituting a hardening furnace, 4 denotes a sorting coil, and 5 and 6. (7), (8), and (9) are hardening containers for 10, 50, and 100 won, respectively, and (71) and (81) are for 10 and 50 won hardening. Window, (SW ₁ ), (SW ₂ ), (SW ₃ ) are detectors to detect hardening, respectively, the dotted arrows A and B indicate the direction in which the hardening separated by the gate 5 is guided, respectively, and A is stored. Direction, B indicates the return direction.

The detectors SW ₁ , SW ₂ , and SW ₃ are, for example, light emitting diodes and phototransistors.

The hardening injected from the inlet 2 is driven on the linear projection 3 to pass through the positions of the first detector SW ₁ , the sorting coil 4, and the second detector SW ₂ , and thereafter. According to the sorting state, for example, when the input hardening is normalized, the gate 5 is recessed in the passage, and in the case of forgery, the gate 5 protrudes in the passage, and thus the storage direction A or the return direction as indicated by the dotted line. Guided by B

The hardening guided in the A direction is divided by the gate 6 according to the type of money when the detector SW ₃ is reached.

According to the present invention, the continuous input of curing is detected by the detectors SW ₁ and SW ₂ , and the next dose is first inputted before the curing is first passed through the detector SW ₁ to reach the detector SW ₂ . If cure is reached, the sensor (SW ₁₎ is placed to project the gate 5 in the passage.

In this case, the coin hardened continuously and transmitted at a predetermined interval is prevented from returning to the storage direction by the gate 5.

In addition, when the hardening reaches the detector SW ₂ , the appearance state of the gate 5 is controlled.

The detectors SW ₁ and SW ₂ are arranged before and after the hardening passage with the sorting coil 4 interposed therebetween, so that the detectors SW ₁ and SW ₂ are placed on the sorting coil 4. It can also be used to determine the selection period of curing by. That is, in the sorting means for sorting the hardening with the bridge circuit including the sorting coil 4 on one side and the standard impedance, the bridge is equilibrated when the normalization passes through the position of the sorting coil 4, but it is normalized. In the case of forgery having the same material as and having a diameter larger than normalization, the bridge is in equilibrium when the forgery advances to the region of the sorting coil 4 and passes through the position of the sorting coil 4.

Therefore, it is advantageous to select as normalization when the bridge equilibrium appears only once within the selection period. The gate 6 which distinguishes the normalization according to a large type is controlled when the hardening reaches the position of the detector SW _3. For example, when the input hardening is 10 won or 50 won, the gate 6 is formed on the path. In the case of 100 won, the gate 6 is recessed in the passage.

The 10 won and 50 won divided by the gate 6 are driven in the direction of arrow C, the 50 won exits the sorting window 81 and falls to be stored in the storage box 8, and the 10 won is sorting window 71. ), It drops out and is stored in the storage container 7.

Moreover, since 100 won divided | segmented by the gate 6 is not prevented by it, it falls as it is and is accommodated in the storage container 9.

Next, continuous closing prevention and gate control will be described with reference to FIGS. 2 and 3.

In FIG. 2, (SW ₁₁ ), (SW ₂₁ ), and (SW ₃₁ ) are input terminals of detection signals of detectors SW ₁ , SW ₂ , and SW _3, respectively. ), (100) are input terminals for selection signals of 10, 50, and 100 won respectively, (FF ₁ ) is a JK flip-flop circuit, and (FF ₂ )-(FF ₆ ) are RS flip-flop circuits (hereinafter simply FF). ₁ -FF ₆ ), (AD ₁ )-(AD ₇ ) are end circuits (hereinafter simply AD ₁ -AD ₇ ), and (OR ₁ )-(OR ₂ ) are ora (hereafter simply OR _1, OR ₂ referred to), (C) a condenser, (G ₁₎ (G ₂₎ denotes a gate signal output terminal for transmitting the gate signals for controlling the gate (5) and (6).

When the input hardening is detected by the detector SW ₁ , FF ₁ is set via the terminal SW ₁₁ , and the input hardening is detected by the detector SW ₂ before the terminal FF ₁ is returned. In SW ₁₁ ), when the detection signal indicating the next input hardening is given, FF ₂ is set so that the input hardening is continued.

That is, prior to the first input of the successive curing inserted coins past a sensor (SW ₁₎ reaches the sensor (SW ₂₎ is cured, and then put in reaching the sensor (SW ₁₎ is set the FF _2.

단자에 접속된 콘덴서(C)에 의한 극히 짧은 시간 지연뒤에 FF₂및 FF₃이 복귀된다.Given by way of the terminal (SW ₂₁₎ is cured detection signal from the detector (SW ₂₎ to the return port (R) of the FF ₁ and FF ₁ is returned, the FF ₁ Thereby

After an extremely short time delay by the capacitor C connected to the terminal, FF ₂ and FF ₃ are returned.

Although the return input of FF ₂ is a short time, it delays, so that when the detection signal is given to the multiple switch SW ₂₁ almost simultaneously after the terminal SW ₁₁ , FF ₂ must be set and then returned.

FF ₃ is set as a sorting signal means normalization in the sorting means (not shown) having the sorting coil 4 described above from the terminals 10, 50, 100.

This FF ₃ is selected during the selection period between the detection of the detection signal at the terminal SW ₁₁ to FF ₁ and the return input signal of FF ₃ to be released and then the return of the FF ₁ via the terminal SW ₂₁ . When set, remember that normalized hardening was added.

FF ₄ is set when FF ₂ is returned and FF ₃ is set, and a detection signal is given at the terminal SW ₂₁ .

This is the case where the input hardening is separated by a predetermined interval or more and this hardening is normalization.

When FF ₄ is set, a gate signal is output from the terminal G ₁ .

On the other hand, the return of FF ₄ is performed when the detection signal is given from the terminal SW ₂₁ when FF ₂ is set or when FF ₃ is returned. That is, the recovery of FF ₄ is performed when the input hardening is continuously transmitted at a predetermined interval or less, or when counterfeiting is input.

The gate signal output from the terminal G ₁ to the gate 5 recesses the gate 5 in the passage when FF ₄ is set, and protrudes the gate 5 when FF ₄ is returned.

FF ₅ is set as the selection signal is given at the terminal 100, and a return input is given by the selection signal given via OR ₂ at either of the terminals 10 and 50.

Further FF ₆ is a FF ₅ is set, the terminal (SW ₃₁₎ is set when the detection signal input from, and return is the FF ₅ returned and terminals (SW ₃₁₎ the detection signal jueojyeoseo-and condition of AD ₇ in It is done when this is established.

That is, FF ₅ is set while the selection signal is given from the terminal 100, and FF ₆ is set when the detector SW ₃ detects hardening with FF ₅ set, and at the (Q) terminal of this FF ₆ The gate signal is sent to the gate 6 through the terminal G ₂ to sink the gate 6 in the passage.

The terminal 10, which appears, on one side of the selection signal 50 is FF ₅ is returned to the return input given to the return port (R) of the FF _5.

FF ₆ is returned when 10-membered and 50-membered curing is detected by the detector SW ₃ after FF ₅ is restored as described above.

If the gate 6 is recessed in the passage at this time, the gate 6 protrudes on the passage.

Therefore, when the input hardening is 100 won, the hardening is stored in the storage container 9 without dropping by the gate 6.

In the case where the input hardening is 10 won or 50 won, their hardening is prevented from falling by the gate 6 and transmitted in the direction of the arrow C to distinguish the windows 71 and 81 according to the diameter.

Next, the operation will be described with reference to the waveform diagram shown in FIG. In Fig. 3, (a) to (f) partitioned vertically indicate different states.

The case where the input hardening is transmitted at a distance of more than a predetermined interval and the input hardening is normalized and 100 won will be described.

The waveform diagram at this time is shown in FIG. 3A. This case, the first detector via a standing terminal (SW _11), so that coin is detected by the (SW ₁₎ (hereinafter referred to as simply "1") logic signal "1" is given to the FF ₁ set the FF _1.

단자에는 논리신호 "0"(이하 단지 "0"이라 한다)이 나타남으로 AD₂의 출력은 "0"이 되어 FF₂와 FF₃의 복귀입력 신호가 해제된다.This is the FF ₁

The logic signal "0" (hereinafter referred to simply as "0") is displayed at the terminal, so the output of AD ₂ becomes "0" and the return input signals of FF ₂ and FF ₃ are released.

When the curing is to reach the position of the screening coil 4 is given in FIG. 3 in the coin sorting by a signal represented by C shows the terminal 100 through an OR _{3 1} FF FF ₃ is set.

Subsequently, when the input hardening is detected by the detector SW ₂ , FF ₁ is returned via the terminal SW ₂₁ .

단자의 "1" 출력과 FF₃의

단자의 "1"출력에 의해 앤드조건이 성립해서 FF₄를 세트한다.At this time, terminals (SW ₂₁₎ by the given "1" in the AD AD _{3 3} is, the FF ₂

"1" output of terminal and FF ₃

The end condition is satisfied by the "1" output of the terminal, and FF ₄ is set.

When FF ₄ is set, " 1 " is output from the gate terminal G ₁ at the same time, and the gate 5 shown in FIG. 1 is recessed in the passage to guide the curing in the storage direction.

단자에서 "1"이 출력되고, 검지기(SW₂)에 의한 경화의 검지신호 보다도 조금 늦어서 AD₂의 앤드조건을 만족시키고 FF₂와 FF₃에 복귀입력이 주어져 FF₂및 FF₃이 복귀한다.If FF ₁ is returned by the detection signal from the terminal SW ₂₁ as described above, the

"1" is output from the terminal, the probe than a little late satisfy the end condition of the AD ₂ and given the return input to the FF ₂ and FF ₃ detection signals of curing by (SW ₂₎ and returns the FF ₂ and FF _3.

As FF ₃ returns, "1" is given to one input of AD ₄ , but the output of AD ₄ is "0" because no detection signal is given via ruler (SW ₂₁ ).

On the other hand, when the selection signal appears at the terminal 100, FF ₅ is set and "1" is applied to one input of AD _{6 at} the terminal (Q).

And if the input coin passes through the gate 5 as described above reaches the position of the detector (SW ₃₎ to call out the detection signal from the detector (SW _3).

This detection signal is given to the other input terminal of AD ₆ via the terminal SW ₃₁ , and thus the set input is given to FF ₆ since the end condition of AD ₆ is established.

As FF ₆ is set, the gate signal "1" is sent to the gate 6 via the gate terminal G ₂ , and the gate 6 is recessed in the hardening passage. Therefore, the above-mentioned hardening is dropped without being blocked by the gate 6 and stored in the storage container 9.

Next, although the space | interval of input hardening falls more than predetermined | prescribed space | interval, the case where the hardening is forgery is demonstrated. The waveform diagram at this time is shown in FIG.

As shown in FIG. 3B, the input hardening is first detected by the detector SW ₁ , whereby FF ₁ is set.

Then since the input coin reaches the position of the screening coil 4 but conditioner above the terminals 10, 50 and 100 via the OR ₁ at FF ₃ is not given a set of input signal FF ₃ is returned The state continues.

When the curing of the electric sensor (SW ₂₎ is detected back at the same time as the FF ₁ return, AD ₄ to the detection signal to the one input is the FF ₃ because the return state the end condition is satisfied return signal to the FF ₄ Gives.

As a result, FF ₄ is returned because the (Q) terminal of the dat "0", and outputs the gate signal "0" via the gate terminal (G _1).

The gate 5 recessed in the passage by the last sorting operation by this gate signal protrudes into the passage, prevents the drop in the storage direction of the input hardening, and distinguishes it in the return direction.

On the other hand, the gate 6 continues to be recessed in the passage as no selection signal is given at the terminals 10 and 50 and FF ₅ and FF ₆ continue to be set. Next, the case where the curing is continuously added and these curings are transmitted at intervals of a predetermined interval or less, and the firstly added curing is normalized (assuming 10 won), and the subsequent curing is forged.

The waveform diagram at this time is shown in FIG. 3C.

In the same manner as above, when the coin put in the first place is detected by the detector SW ₁ , FF ₁ is set by the detection signal, and the return inputs of FF _{2 and} FF ₃ are released.

When the input hardening reaches the position of the selection coil 4, the set input is given to FF ₃ via OR ₁ at the terminal 10, and the return input is given to FF ₅ via OR ₂ at the terminal 10. .

After that, the hardening that is injected next reaches the position of the detector SW ₁ before the input curing reaches the position of the detector SW ₂ , so that it is connected to one input terminal of the AD ₁ via the terminal SW ₁₁ . "1" is given.

At this time, since " 1 " of the (Q) terminal of FF ₁ is given to the other input terminal of AD _1, the end condition is satisfied, FF ₂ is set, and it is stored in FF ₂ that hardening is transmitted at a predetermined interval or less.

When the coin put in the first time reaches the position of the detector SW ₂ and is detected, “1” is given to one input terminal of the AD ₅ via the terminal SW ₂₁ , and this AD ₅ has FF ₂ set therein. The sur- end condition is satisfied and a return signal is sent to FF ₄ .

At this time, since FF ₄ has already returned from the previous sorting operation, the return state continues, and the gate 9 protrudes into the passage.

Of course, when FF ₄ is set and FF ₂ is set, and when the AND condition of AD ₅ is established, FF ₄ is returned to protrude the gate 5 recessed in the passage into the passage.

When a detection signal is input from the terminal SW ₂₁ , FF ₁ is returned, whereby FF ₂ and FF ₃ are returned to a standby state.

On the other hand, while FF ₅ is in the return state with the selection signal given from the terminal 10 as described above, FF ₆ is still in the set state.

As described above, since the gate 5 protrudes in the passage, the continuously added curing is divided in the return direction B. FIG.

Next, the case where the continuously added curing is transmitted at a predetermined interval or less, and any of these curing are forged will be described. The waveform diagram at this time is shown in FIG.

When the coin put in the first place is detected by the detector SW ₁ , FF ₁ is set, whereby the return signals of FF _{2 and} FF ₃ are released.

Then, the curing entered next before this curing reaches the position of the detector SW ₂ is detected by the detector SW ₁ , so that FF ₂ is set via the AD ₁ , and continuous feeding is stored.

Since the coin put in the first place is counterfeit even when passing through the position of the sorting coil 4, the sorting signal is not input at the terminals 10, 50, and 100. Subsequently, when hardening initially applied is detected by the detector SW ₂ , a return signal is given to FF ₄ via AD ₅ .

At this time, since FF ₄ has returned from the previous time, the state continues and the gate 5 protrudes into the passage.

Via a terminal (SW ₂₁₎ as described above, a detection signal is given to the FF FF _{1 1} is returned, and then enters a standby state to a recovery signal jueojyeoseo FF _2, FF _3.

Next, the case where the input curing is normalized (set to 50 won) and only this curing is added will be described.

The waveform diagram at this time is shown in FIG. When the input hardening is detected by the detector SW ₁ , FF ₁ is set and the return input signals of FF ₂ and FF ₃ are released.

When the input hardening passes through the detector SW ₁ and reaches the sorting coil 4, a sorting signal is input to the terminal 50, FF ₃ is set via OR ₁ , and returns to FF ₅ via OR ₂ . Signal is given.

At this time, since FF ₅ has been set previously, the return state is continued. After that, when the input hardening is detected by the detector SW ₂ , AD _{3 which} uses this detection signal as one input inputs a set to FF ₄ because the end condition is established while FF ₂ is in a return state and FF ₃ is set. Gives.

This causes the FF ₄ is set, sending a "1" via the gate terminal (G _1), and a recessed gate 5 in the passage by.

As described above, when the detection signal is input from the terminal SW ₂₁ , FF ₁ is returned, and then a return input signal is supplied to the FF _{2 and} FF ₃ to be in a standby state. The input hardening that has passed through the position of the detector SW ₂ is guided in the storage direction A without being blocked by the gate 5 and is detected by the detector SW ₃ .

When the input hardening is detected by the detector (SW ₃ ), the AD ₇ returns the input signal to FF ₆ because the end condition is satisfied because FF ₅ is returned. When FF ₆ is returned, " 0 " appears at its (Q) terminal to protrude the gate 6 into the passage.

As a result, the input hardening is prevented from falling by the gate 6 and is divided in the direction of the arrow C, passed through the sorting window 81, and stored in the storage 8.

Next, the case where three hardening | curings are thrown in continuously and the 1st and 2nd hardening and the 2nd and 3rd hardening are respectively transmitted below predetermined distance is demonstrated.

The waveform diagram in this case is shown in FIG. 3 (f). If the FF ₁ and FF ₂ set by curing and hardening of the second of the first continuously injected and subsequently curing of the first reaches the position of the detector (SW ₂₎ via the AD ₅ are given the return input to the FF _4.

As a result, the gate 5 protrudes into the passage to return the input hardening. Then, before the second input hardening reaches the position of the detector SW ₂ , FF ₁ is set again by the third input hardening, but the second hardening is returned when the second hardening reaches the position of the detector SW ₂ . .

As a result, the return state of the FF ₄ is not changed at all, so that the gate 5 continuously returns the input hardening state.

According to the present invention as described above, when the continuously added curing is being transmitted at a predetermined interval or less, these can be reliably returned. Therefore, after normalization, forgery is guided to the storage direction, causing clogging or being stored in the storage container. I do not throw it away.

In the case of normalization, forgery, or normalization, the control of the gate for distinguishing the input hardening by money type is performed while confirming the transmission position of the input hardening, so that the hardening can be reliably distinguished, and Since the change of the appearance appearance is carried out as needed without being switched for every sorting operation of the input hardening, it has the advantage of suppressing the fatigue of the electromagnet for leaving the gate in the passage, for example.
