〔Example〕

FIG. 1 is a side sectional view showing an embodiment of a coin processing apparatus according to the present invention, centering on a coin discriminating section.

In FIG. 1, the coin processing apparatus comprises a coin receiving section 10 protruding forward and a main body section 30. Below the main body section 30, as shown in FIGS. In addition, a plurality of coin tubes as coin storage units are provided.

When the coin processing apparatus of this embodiment is mounted on, for example, a vending machine, the coin is inserted so that the coin slot 11 of the coin receiving unit 10 faces directly outside the vending machine.

The coin slot 11 has a light-emitting part with a light-emitting element housed inside
12 is installed. The light emitting unit 12 is provided to enable a user such as a vending machine equipped with the coin processing device to easily identify the coin slot 11, especially at night. It is effective for use, etc.
The operability of a vending machine or the like equipped with the coin processing device is improved.

By the way, in the coin processing apparatus of this embodiment, a coin discriminating path by belt conveyance is adopted in order to reduce the vertical dimension of the coin discriminating section. If a coin discriminating path by belt conveyance is adopted, if foreign matter other than coins is drawn into the belt conveying path, it will cause mechanical jamming, and in this case, the vending machine equipped with this coin processing device until the foreign matter is removed Will not be available. Given that vending machines are mostly unmanned,
This mechanical jam often delays discovery, in which case it misses out on sales opportunities.

Therefore, in this embodiment, an entrance sensor SEIN that performs primary detection of the inserted coin is provided at the coin insertion slot 11. This entrance sensor SEIN removes foreign substances inserted from the coin insertion slot 11 and detects that a coin has been inserted into the coin insertion slot 11, and a proximity switch using a coil that reacts only to available coins. Consists of

The shutter 13 blocks foreign objects inserted from the coin slot 11 and regulates coins inserted from the coin slot 11. The shutter 13 is driven by a shutter solenoid SOLSH that operates based on the output of the entrance sensor SEIN. You. The operation state of the shutter 13 is detected by a shutter sensor SESH.

The belt transport path 14 is a pair of upper and lower transport belts 14a and 14
b, composed of rollers 15a, 15b, 15c, 15d and 16a, 16b, 16c, 16d for driving these belts, and rollers 15a, 15b, 15c
The shaft of the roller 17a, 17b, 17c, and the rollers 16a, 16b, 1
The shaft 6c is resiliently supported by springs 18a, 18b, 18c, respectively, so that coins of various thicknesses can be conveyed. The roller 16d is driven by a belt conveying motor MO via a reduction gear system 19 as shown in the rear view of FIG. 1 shown in FIG. 3, and the other rollers 16a, 16b, 16c correspondingly move the conveying belt 14b. And the rollers 15a, 15b, 15c, 15d are driven via conveyor belts 14b, 14a.

A gate sensor SEGE and a sorting sensor SECO are provided on the belt transport path 14 along the belt transport path 14.

The gate sensor SEGE is disposed at a position away from the coin insertion slot 11 by a distance corresponding to the maximum diameter of the coins used, that is, at a position where the coin inserter cannot operate the coin.
In this embodiment, coin sorting processing is started by turning on the gate sensor SEGE. Here, for example, it is also conceivable to start the coin sorting process by turning on the entrance sensor SEIN without providing the gate sensor SEGE.In this case, for example, coins are put in and taken out of the entrance sensor SEIN disposition unit due to mischief. By this, when the entrance sensor SEIN is turned on and off, the coin sorting process is started each time, and the amount of software for coin sorting process increases,
Also, the processing becomes complicated. Therefore, in the present embodiment, the coin sorting process is started by turning on the gate sensor SEGE disposed at a position where the coin cannot be operated by the coin inserter. This gate sensor SEGE
Is composed of a light-emitting element and a light-receiving element disposed on both sides of the belt transport path 14, and optically detects coins transported on the belt transport path 14.

The sorting sensor SECO determines the authenticity and denomination of coins conveyed on the belt conveyance path 14. This sorting sensor SECO is composed of an oscillating coil excited by an excitation signal of a predetermined frequency and a receiving coil for receiving the output of the oscillating coil, which is disposed across the belt transport path 14, and is guided along the belt transport path 14 to be guided. The authenticity and denomination of the coin are discriminated from the attenuation waveform generated in the reception coil when the coin whose one edge is guided by 20 passes between the oscillation coil and the reception coil. That is, in this embodiment, four coins of 500 yen, 100 yen, 50 yen, and 10 yen are assumed as coins to be used, and the peak value of the attenuation waveform generated in the receiving coil is 500 yen.
Compare with the window values set in advance for circles, 100 yen, 50 yen and 10 yen, and when the peak value of the attenuation waveform falls within the window value corresponding to 500 yen, it corresponds to 500 yen and 100 yen 100 yen when entering the window value, 50 yen when entering the window value corresponding to 50 yen, 1
If it is within the window value corresponding to 0 yen, it is determined to be 10 yen and 500
If it does not fall into any of the window values of yen, 100 yen, 50 yen, and 10 yen, it is determined as a fake. The pull-out prevention lever 21 provided on the belt transport path 14 is for preventing illegal operation of pulling out a coin once passing a coin sensor by connecting a thread or the like to the coin, for example.

Coins passing through the belt transport path 14 and falling from the belt transport path 14 are sorted by the true / false coin sorting lever LVSF,
The genuine coin is led to the genuine coin passage PS, and the fake coin is led to the fake coin passage PF. The true / false coin sorting lever LVSF is driven by a true / false coin solenoid SOLSF which operates based on the discrimination output of the sorting sensor SECO. That is, when the coin discriminated by the sorting sensor SECO is a counterfeit coin, the counterfeit coin solenoid SOLSF is not energized (off), and the counterfeit sorting lever LVSF is at the position shown by the dotted line in FIG. Coins falling from the belt transport path 14 are guided to the fake coin path PF. If the coin determined by the sorting sensor SECO is a genuine coin of 500 yen, 100 yen, 50 yen, or 10 yen, the genuine and false coin solenoid SOLSF is excited (ON), thereby The coin distribution lever LVSF is switched to the position shown by the solid line in FIG. 1, whereby coins falling from the belt transport path 14 are guided to the true coin path PS.

In addition, the control unit 100 controls the belt transport motor MO, shutter solenoid SOLSH, genuine counterfeit solenoid SOLSF, 500 yen solenoid SOL500, 100 yen solenoid SOL100, 10 yen solenoid SOL10, and 50 yen solenoid SOL based on the outputs of these sensors.
Control 50.

The control unit 100 includes an internal auxiliary device inventory switch DE, an external auxiliary device inventory switch ZWD, a 500 yen inventory switch IV 500, and a 100 yen inventory switch IV.
The sorting accuracy of coins is switched using the output of the 100 and 10 yen inventory switch IV10 and the 50 yen inventory switch IV50.

Hereinafter, the operation of the control unit 100 will be described with reference to the flowcharts shown in FIGS. 7 to 12.

FIG. 7 shows the main flow of this apparatus. In FIG. 7, when the power is turned on to the apparatus, first, a predetermined initialization process is executed (step 101), and thereafter, the coin receiving accuracy is switched as required (step 10).
2). Details of this coin acceptance accuracy switching are shown in FIGS. 8 to 11 described later.

Next, the abnormality of each part of the device is checked (step 10).
3). If no abnormality is detected by this abnormality check,
A coin accepting process for enabling coin acceptance is executed (step 104).

Here, when a coin is inserted, a coin sorting process is executed (step 105). The details of the coin sorting process are shown in FIG. 12 described later.

Subsequently, it is determined whether or not there is a coin payout command (step 106). Here, when there is a coin payout command, a coin acceptance impossible process for inhibiting acceptance of coins is executed (step 107).

If it is determined in step 106 that there is no coin dispensing instruction, it is next checked whether or not the inventory switch is turned on (step 111). Here, if the inventory switch is turned on, a coin acceptance rejection process for inhibiting acceptance of coins is executed (step 112).

The reason why the coin rejection processing is executed in steps 107 and 112 is that if coins are inserted during a coin payout operation or an inventory operation, control becomes impossible.

After the coin rejection process is executed, the coin sorting process is executed again (step 108). Here, the reason for performing the coin sorting process is to sort coins that have been inserted before coins are accepted and have not been sorted.

When the final coin sorting is completed by this coin sorting process (step 109), a coin payout process is executed (step 110).

Coin acceptance precision switching The details of the coin acceptance precision switching operation are shown in FIG. 8 to FIG. The switching of the coin receiving accuracy is performed by using an inventory switch provided for a coin collecting operation of each tube. The inventory switch includes an internal auxiliary device inventory switch DE for instructing the operation of collecting coins stored in the internal auxiliary device (corresponding to the auxiliary tubes CTD and CTE shown in FIG. 5), and an external auxiliary device (not shown). External auxiliary machine inventory switch for commanding coin collection operation
ZWD, 500 yen inventory switch IV500 that commands the operation of collecting coins stored in 500 yen tube CT500, 100 that orders the operation of collecting coins stored in 100 yen tube CT100
A circle inventory switch IV100, a 10-yen inventory switch IV10 for instructing a collection operation of coins stored in a 10-yen tube CT10, and a 50-yen inventory switch IV50 for instructing a collection operation of coins stored in a 50-yen tube CT50 are provided. I have.

By the way, since the inventory switch is provided for collecting change as described above, it is necessary to distinguish an operation for collecting original change from an operation for changing the coin receiving accuracy, and Since the mode must not be shifted to the coin receiving accuracy switching mode during the normal work operation, it is configured not to shift to the coin receiving accuracy switching mode unless the following procedure is performed. In other words, the internal auxiliary equipment inventory switch DE and the external auxiliary equipment inventory switch ZW
D is turned on, and thereafter, only when the power is turned on, the mode is shifted to the coin receiving accuracy switching mode.

In FIG. 8, first, it is checked whether both the internal auxiliary device inventory switch DE and the external auxiliary device inventory switch ZWD are turned on (step 201), and both the internal auxiliary device inventory switch DE and the external auxiliary device inventory switch ZWD are turned on. If so, a monitor lamp blinking process for controlling blinking of a monitor lamp (not shown) is executed (step 202).

The operator knows from the blinking of the monitor lamp that the coin receiving accuracy switching mode has been set.

By the way, in this embodiment, when the 500 yen inventory switch IV500 is turned on, the normal switching mode is set to the normal accuracy. When the 100 yen inventory switch IV100 is turned on, the accuracy is increased to the 1st accuracy switching mode.
Increase accuracy by turning on the circle inventory switch IV50 2
It is configured to shift to the accuracy-up 2 switching mode to the accuracy. Here, the normal accuracy is a normal coin acceptance accuracy, and the accuracy up 1 accuracy is a stricter coin acceptance accuracy compared to the normal accuracy. The coin is substantially prohibited from being accepted. By setting the accuracy to 2 accuracy, the denomination of accepted coins can be restricted from 4 denominations to 1 denomination.

If the 500 yen inventory switch IV500 is turned on in the coin acceptance accuracy switching mode (step 203), the buzzer sounds once (step 204), and the mode shifts to normal switching (step 205), and the 100 yen inventory switch IV10
When 0 is turned on (step 207), the buzzer is sounded twice (step 208), and the operation is shifted to the accuracy up 1 switching (step 209). When the 50 yen inventory switch IV50 is turned on (step 210), the buzzer is sounded. Is sounded three times (step 211), and the process proceeds to the switching of the accuracy up 2 (step 21).
2). The details of the normal switching are shown in FIG. 9, the details of the switching of the accuracy up 1 are shown in FIG. 10, and the details of the switching of the accuracy up 2 are shown in FIG. In addition, when each switching operation is completed, or after entering the coin acceptance accuracy switching mode, a certain time has elapsed without turning on any of the 500 yen inventory switch IV500, the 100 yen inventory switch IV100, and the 50 yen inventory switch IV50. In this case (step 213), the monitor lamp blinking process ends (step 206), and the coin acceptance accuracy switching flow ends.

Normal Switching In the normal switching mode shown in FIG. 9, when the 500 yen inventory switch IV500 is turned on, the sorting accuracy for the 500 yen coin is switched to the normal accuracy, and when the 100 yen inventory switch IV100 is turned on, 100 yen. The sorting accuracy for coins is switched to normal accuracy, the sorting accuracy for 50 yen coins is switched to normal accuracy when the 50 yen inventory switch IV50 is turned on, and the 10 yen coin is switched for normal accuracy when the 10 yen inventory switch IV10 is turned on. The sorting accuracy is switched to the normal accuracy. In addition, when a return switch (not shown) that is turned on to instruct the return of coins is turned on, or when a coin is inserted into the coin insertion slot and the entrance sensor SEIN is turned on, the normal switching mode is forcibly set. It is released.

That is, in FIG. 9, first, it is determined whether or not the return switch is turned on (step 221). If the return switch is not turned on, then it is determined whether or not the entrance sensor SEIN is turned on. (Step 222). Here, if the entrance sensor SEIN is not turned on, then the 500 yen inventory switch IV500 is turned on (step 22).
3) Whether the 100 yen inventory switch IV100 is turned on (step 224), the 50 yen inventory switch IV5
0 is turned on (step 225), and the 10 yen inventory switch IV10 is turned on (step 22)
6), are checked sequentially. Here, 500 yen inventory switch IV500, 100 yen inventory switch IV100, 50 yen inventory switch IV50, 10 yen inventory switch IV10
Is turned on, the buzzer sounds once (step 229), the acceptance accuracy of coins of the denomination corresponding to the inventory switch that has been turned on is switched to normal accuracy, and the contents are stored in a control memory (not shown). It is stored (step 230). As a result, thereafter, the acceptance accuracy of each coin is switched based on the acceptance accuracy stored in the control memory.

If the return switch or the entrance sensor SEIN is turned on (steps 221 and 222), or even if a predetermined set time has elapsed since the mode was switched to the normal switching mode, 50 minutes have elapsed.
If none of the 0 yen inventory switch IV500, the 100 yen inventory switch IV100, the 50 yen inventory switch IV50, and the 10 yen inventory switch IV10 are turned on (step 227), the buzzer sounds once (step 2).
28) End this normal switching mode.

The sorting accuracy for 50-yen coins is switched to 1-accuracy and the 10-yen inventory switch IV10 is turned on. Then, the sorting accuracy for the 10-yen coin is switched to the accuracy up 1 accuracy. In addition, when a return switch (not shown) that is turned on to instruct the return of coins is turned on, or when a coin is inserted into the coin insertion slot and the entrance sensor SEIN is turned on, this accuracy-up 1 switching mode is performed. Forcibly released.

That is, in FIG. 10, first, it is checked whether or not the return switch is turned on (step 231). If the return switch is not turned on, then it is checked whether or not the entrance sensor SEIN is turned on. (Step 232). Here, if the entrance sensor SEIN is not on, the 500 yen inventory switch IV500 is turned on next (step 23).
3) Whether the 100 yen inventory switch IV100 is turned on (step 234), the 50 yen inventory switch IV5

3) Whether the 100 yen inventory switch IV100 is turned on (step 244), the 50 yen inventory switch IV5
0 is turned on (step 245), and the 10 yen inventory switch IV10 is turned on (step 24)
6), are checked sequentially. Here, 500 yen inventory switch IV500, 100 yen inventory switch IV100, 50 yen inventory switch IV50, 10 yen inventory switch IV10
Is turned on, the buzzer sounds once (step 249), the acceptance accuracy of coins of the denomination corresponding to the turned on inventory switch is switched to the accuracy up 2 accuracy, and the contents are not shown. It is stored in the memory (step 250). As a result, thereafter, the acceptance accuracy of each coin is switched based on the acceptance accuracy stored in the control memory.

If the return switch or the entrance sensor SEIN is turned on (steps 241 and 242), or even if a predetermined set time has elapsed since the switching to the normal switching mode, 50
If none of the 0 yen inventory switch IV500, the 100 yen inventory switch IV100, the 50 yen inventory switch IV50, and the 10 yen inventory switch IV10 are turned on (step 247), the buzzer sounds three times (step 2).
48) This accuracy up 2 switching mode is ended.

Coin sorting process The coin sorting process is shown in FIG. The coin sorting process is configured to start the coin sorting process by turning on the gate sensor SEGE disposed in the belt transport path 14 as described above.

In FIG. 12, first, it is checked whether or not there is a gate sensor ON memory indicating that the gate sensor SEGE has been turned on (step 251). If there is no gate sensor ON memory, it is checked next whether the gate sensor SEGE is on (step 252). If the gate sensor SEGE is not on, it is determined that the entrance sensor SEIN is on next. (Step 253). If there is no entry sensor ON memory here, then enter the entry sensor SE
It is checked whether IN is on (step 254). Here, when the entrance sensor SEIN is not turned on, it is in a standby state in which no coin is inserted from the coin insertion slot 11, so that the coin sorting processing flow ends. This coin sorting process is repeated until a coin payout command is issued, as shown in FIG.

When the entrance sensor SEIN into which a coin has been inserted from the coin insertion slot 11 is turned on, this is determined in step 254 in the next coin sorting process, the shutter solenoid SOLSH is turned on (step 255), and after a certain time (step 256) When the shutter sensor SESH is turned on (step 257), the entry sensor ON memory is stored (step 260), and the transport motor MO driving the belt transport path 14 is rotated forward (step 26).
1), an entrance sensor ON timer (not shown) is started (step 262). This entrance sensor on timer is used to detect a coin jam or an entrance sensor
This is for detecting an illegal coin operation in the SEIN arrangement unit. This entrance sensor ON timer can be realized as a software timer of the control unit 100.

If the shutter sensor SESH is not turned on after a predetermined time from turning on the shutter solenoid SOLSH, the shutter solenoid SOLSH is turned off (step 258), and a predetermined shutter abnormality process is executed (step 259).

When the entry sensor ON memory is determined to exist, in the next coin sorting process, it is determined in step 253 that the entry sensor ON memory is present. In this case, it is next checked whether or not the entrance sensor SEIN has been turned off (step 263). If it has been turned off, whether the motor pulse for detecting the amount of conveyance of the belt conveyance path 14 by the conveyance motor MO has started counting is next started. Is checked (step 267). Here, since the counting of the motor pulse has not been started, the counting of the motor pulse is started (step 268).

If the entrance sensor SEIN is not turned off in step 263, it is checked whether the entrance sensor on timer started in step 262 has expired (step 26).
4) If the time is up, the transport motor MO is stopped (step 265), and an entrance sensor off waiting process for waiting that the entrance sensor SEIN is turned off is executed (step 26).
6).

If it is determined in step 267 that the count of the motor pulses has already started, it is checked whether the count value of the motor pulse is larger than a predetermined value (step 269). The MO is stopped (step 270), and then a predetermined coin jam recovery process is executed (step 271).

The coin transported along the belt transport path 14 is a gate sensor SEGE
When the gate sensor SEGE is turned on (step 252), it is determined that there is a gate sensor ON memory indicating that the gate sensor SEGE is turned on (step 27).
2). Then, counting of motor pulses for detecting the transport amount of the belt transport path 14 by the transport motor MO is started (step 273).

In the next coin sorting process, when it is determined that the gate sensor is on (step 251), it is checked whether or not the sorting sensor SECO indicates that a coin has been detected. Next, it is checked whether or not a coin is detected by the sorting sensor SECO (whether or not the sorting sensor SECO is turned on) (step 275). If the sorting sensor SECO is turned on, it is set that the sorting sensor ON memory is present ( Step 276). But the sorting sensor SEC
If O is not on, it is checked whether the count value of the motor pulse is larger than a predetermined value (step 26).
9) If it is larger, stop the transport motor MO (Step 27)
0) Then, a predetermined coin jam recovery process is executed (step 271). If the count value of the motor pulse is smaller than a predetermined value, the coin sorting process is terminated, and the process waits until the sorting sensor SECO is turned on.

When the sorting sensor SECO is turned on and the setting of the sorting sensor ON memory is set, in the next coin processing, step 274 is performed.
, It is determined that the sorting sensor is on, and "coin sorting" is executed (step 277). "Coin sorting" is based on the discrimination output of the sorting sensor SECO, and discriminates between genuine and bad coins, and 500 yen solenoid SOL500, 100 yen solenoid SOL10
0, 10 yen solenoid SOL10 and 50 yen solenoid SOL50 are set and stored in the permission (excitation) permission state. In the processing of genuine coins and bad coins to be described later, 50
Controls the 0 yen solenoid SOL500, 100 yen solenoid SOL100, 10 yen solenoid SOL10, 50 yen solenoid SOL50, and true and false coin solenoid SOLSF.

When the sorted coins are set as genuine coins, that is, "genuine coin = 1" by "coin sorting" (step 278), genuine coin processing is subsequently performed (step 279). In specie processing,
The true / false coin solenoid SOLSE is turned on, and the true / false coin distribution lever LVSF guides the true coin to the true coin passage PS to execute the true coin distribution process.

Further, when the coins sorted by the "coin sorting" are set as bad coins, that is, "genuine coin = 0" (step 278), bad coin processing is subsequently performed (step 280). In the processing of bad coins, the true and false coin solenoid SOLSE is kept off, and bad coins are led to the false coin passage PF by the regular and false coin sorting lever LVSF.
