And a controller for comparing the received voltage transmitted from the sensor unit and sending out a true fake determination signal of the coin and a determination signal for each coin type according to the comparison result. In the conventional coin sorting device, a plurality of solenoids that divide the coin passages by signals transmitted according to the controller's determination result are operated separately, thereby dividing the fake coins by the real fake coins and the types of coins, and converting the fake coins into the predetermined coin passages. Then, the real coins are guided to predetermined coin passages formed for each coin type.

By the way, according to the above-described conventional coin sorting apparatus, real fake coins are selected, and the selected real coins are five kinds of coins having different diameters, respectively, and five kinds of coins having different diameters are further selected by coin type. The solenoids that must be operated according to the discrimination signal of the coin discriminating device need at least 5, including the solenoids that divide real coins and fake coins, and the solenoids that divide by coin type. As the device itself becomes large and expensive, the assembly process is complicated, and many solenoids are operated, which complicates the circuit configuration of the coin discrimination device, requires expert knowledge during maintenance checks, and enables simple operation. There was no such problem.

In view of these points, the present invention provides a coin sorting apparatus for selecting real coins and fake coins with a simple structure and further selecting five kinds of real coins having different selected diameters by type of coins, without using a plurality of solenoids. The purpose.

In order to solve the above-mentioned problems, the present invention has an electronic coin discrimination apparatus that determines a real fake of an input coin and a kind of coins regarded as a real coin, and selects a real coin and a fake coin, respectively, and considers it as a real coin. In a coin sorting device for sorting five coins of A, B, C, D, and E having different diameters, the coin is operated by operating the first lever in accordance with the coin genuine fake determination signal of the coin discriminating device. And the first solenoid plunger 40, which divides the real coins and the fake coins H of the different diameters A, B, C, D and E into H and separates the real and fake coins into separate coin passages.

Divided into groups of coins And a second solenoid plunger for separating and guiding a group of coins other than coins A and coins A into separate coin passages, and operating a third lever in accordance with the determination signal for each coin type of the coin sorting device. The coin group is divided into coin groups of coin B and coin C and coin groups of coin D and coin E, and the coin groups of coin B and coin C are divided into coin B and coin C according to the diameter difference. A third solenoid plunger is provided for separating and guiding the coin passage of the coin D and the coin E into the coin passage having a coin sorting device for dividing the coin group of the coin D and the coin E according to the difference in diameter.

According to the above-mentioned coin sorting device, the total number of solenoid plungers operated by the coin sorting device, dividing real coins and fake coins, and dividing 5 kinds of real coins with different diameters by coin type is 3 in total. The number of uses of the plunger can be greatly reduced.

Hereinafter, an embodiment of the coin sorting apparatus according to the present invention will be described in detail.

1 is a conceptual sectional view of the coin sorting apparatus 1 according to the present invention. In particular, the coin sorting apparatus 1 performs sorting of genuine fake coins and sorting coins of five kinds of genuine coins having different diameters.

This coin sorting device 1 is composed of a main plate 2 formed of a hard polymer material, and a coin inlet 3 is formed on the upper left side of the main plate 2.

The coin inlet 3 communicates with the first coin passage 4 that is inclined in the right direction of the drawing, and in the middle of the first coin passage 4, the sensor 5 of the coin sorting device described later is In response to the detection signal of the sensor 5, the coin sorting device is equipped with five kinds of genuine coins of different diameters A, B, C, D, and E, which are determined to be genuine fakes of the coin put therein and that are determined to be real coins. It is determined whether the coin group other than coin A and coin A or coin group other than coin A is coin group of coin B, C or coin group of coin D, E.

In addition, the sensor 5 is composed of an oscillating coil 6 and a receiving coil (to be described later) disposed to face each other at predetermined intervals. Immediately after the end portion 4a of the first coin passage 4, a first lever dividing the coin passage transmitted from the first coin passage 4 into a real fake coin and guiding it to a separate coin passage (7) is excreted. The end 4a of the first coin passage 4 is driven by the first lever 7 to guide H of fake coins in the coin, as shown in FIG. 2 shown in the FF section of FIG. It is divided into a coin passage (8) and a third coin passage (9) for guiding only real coins.

Moreover, the first lever 7 is always operated by the first solenoid plunger 40 which operates the lever 7 in accordance with the determination signal of the coin discriminating device as shown in FIG. The coin guided from 4) is stopped at the initial position for guiding the second coin passage (8). The second coin passage 8 is formed of a separate cover 10 which covers the rear surface of the main plate 2.

On the other hand, as shown in FIG. 1, in the middle of the third coin passage 3, the real coins transferred into the third coin passage 9, that is, 5 of A, B, C, D, and E having different diameters, respectively. A second lever 11 for dividing the real coins of the kind into coins A and a group of coins other than Coins A; and a group for dividing coins groups other than Coins A into coin groups of coins B and C, and coins D and E groups The lever 12 of 3 is provided.

As shown in FIG. 1, the third coin passage 9 is formed on a substantially vertical lower side of the second lever 11 and has a fourth coin passage 13 for guiding only coin A, A fifth coin passage 14 formed between the lever 11 of the second and the third lever 12 and guiding the coin groups of coins B and C among the coin groups other than coin A; It is formed and divided into a sixth coin passage 15 for guiding the coin groups of coins D and E.

In addition, as shown in FIG. 3 shown in the first main longitudinal sectional view, the second lever 11 is always provided by the second solenoid plunger 41 which operates the lever 11 in accordance with the determination signal of the coin discriminator. It is stopped at the initial position of guiding the real coin guided from the coin passage 9 of the third to the fifth coin passage 14:

As shown in FIG. 3, the third lever 12 is always the sixth coin passage 15 by the third solenoid plunger 42 which operates the lever 12 in accordance with the determination signal of the coin discriminator. ) And the coin guided from the third coin passage 9 is stopped at the initial position for guiding the coin to the fifth coin passage 14.

On the other hand, the first rail-type coin sorting device 16 for sorting coins B and C falling by the difference in diameter in the coin passage 14 of FIG. 5 as shown in FIG. ), The coin passage 14 of FIG. 5 is divided into the coin passage 17 of FIG. 7 and the coin passage 18 of FIG. The first rail coin selecting device 16 pushes the longitudinal holes 19 formed in the front of the fifth coin passage 14 and coins falling into the holes 19 into the holes 19. It consists of a guide plate 20 to be placed, the width W1 of the hole 19 is formed slightly larger than the diameter of the falling coin C and smaller than the diameter of the falling coin B, and the seventh coin passage 17 The width W2 of the coin passage 17 of S is slightly larger than the diameter of coin B.

Therefore, as shown in FIG. 4, when coins B and coins C (diameter of coin B> diameter of coin C) having different diameters are guided in the coin passage 14 of FIG. 5, the width W1 of the hole 19 falls. Since the coin C is slightly larger than the diameter of the coin C, the coin C is pushed into the hole 19 by the guide plate 20 of the first rail-type coin sorting device 16 and separated into the eighth coin passage 18. You are guided.

In addition, since the width W1 of the hole 19 is smaller than the diameter of the falling coin B, the coin B falls directly under the hole 19 without being pushed into the hole 19 by the pressing force of the guide plate 20, It is separated and guided to the coin passage (17).

On the other hand, as shown in FIG. 5 using the same reference numerals for the same parts as in FIG. 1, the sixth coin passage 15 uses the second rail-type coin sorting device 21 to make coins D and coins D out of the coin groups of E. It is divided into a ninth coin passage 22 for guiding and a tenth coin passage 23 for guiding coin E. The second rail coin-selecting device 21 is a window 15b which is inclined at a predetermined angle from the side surface 15a of the sixth coin passage 15 to the right side of the drawing as shown in FIG. 6 shown in the GG cross-sectional view of FIG. And a width from the bottom 15c of the sixth coin passage 15 to the upper edge 15d of the window 15b is slightly larger than the diameter of coin E and less than the diameter of coin D. Formed.

Therefore, when the coins D and E having different diameters are guided in the sixth coin passage 15, the diameter of the coins D is greater than the width to the upper edge 15d of the window 15b. As shown in FIG. 5, the sixth coin passage 15 is straight and separated into the ninth coin passage 22 as shown in FIG. Since the diameter of the coin E is smaller than the width to the upper edge 15d of the window 15b, it is further inclined toward the window 15b side as shown in FIG. 6, and then the sixth coin passage 15 The separation is guided into the tenth coin passage 23 through the hole 24 formed between the tenth coin passage 23.

Next, the five real coins of different diameters A, B, C, D, and E, which are identified as true coins and identified as real coins, are coin groups other than coin A and coin A, or among coin groups other than coin A The coin discriminating apparatus for discriminating whether the coin groups of coins B and C or the coin groups of coins D and E will be described in detail.

7 is a block diagram showing the coin discriminating apparatus 30 described above, and the same parts as those in FIG. 1 are denoted by the same reference numerals.

The coin discriminating device 30 is previously memorized for each coin in accordance with a sensor unit 5 consisting of an oscillator 31, an oscillation coil 6, a receiving coil 32, and a detection signal of the sensor unit 5. The controller 34 includes a controller 34 which compares the attenuation voltage and the allowable range with the received voltage transmitted from the sensor unit 5, and determines the type of real coin and the type of real coin according to the comparison result. When the coin N passed between the oscillating coil 6 and the receiving coil 32 is a fake coin, the controller 34 does not transmit a drive signal to any solenoid plunger, and also receives the oscillating coil 6 and the receiving coil. If the coin N passed between the coils 32 is a genuine coin and is determined to be coin A, a drive signal is sent to the first and second solenoid plungers 40 and 41. When the coin N passed between the oscillating coil 6 and the receiving coil 32 is a real coin and is identified as a coin group of coins B and C, the drive signal is transmitted only by the first solenoid plunger 40. If the coin N passed between the oscillating coil 6 and the receiving coil 32 is a real coin and is identified as a coin group of coins D and E, the first solenoid plunger 40 and the third solenoid plunger ( 42) Sends drive signal only.

Next, the operation of the coin selecting device 1 described above will be described, and the configuration will be described in more detail.

If the coin H, which is injected from the coin inlet 3, is the fake coin by the coin discriminating device 30 of FIG. Since the drive signal is not sent out, the first lever 7 stops at the initial position shown in FIG. 2, and the second and third levers 11, 12 also show the initial position shown in FIG. Each is stopped at. Therefore, as shown in FIG. 2, the fake coin H, which transmits the first coin passage 4, is guided to the second coin passage 8 by the first lever 7 and then not shown. Retreat to the coin retreat.

Next, when coin A is introduced from the coin inlet 3 with the same reference numeral 9 as shown in FIG. 1, the coin is the real coin and the coin type is coined by the coin discriminator 30 of FIG. Since it is determined as A, the drive signal of the first solenoid plunger 40 and the drive signal of the second solenoid plunger 41 are transmitted by the controller 34. Therefore, the first lever 7 rotates clockwise by an angle as shown in FIG. 10 shown in section II of FIG. 9 to open the third coin passage 9, and the second lever 11 is made of the 9th. As shown in the figure, the counterclockwise direction rotates by a predetermined angle and stops at the position where the fourth coin passage 13 is opened. According to the stop positions of the first and second levers 7 and 11, the coin A having passed through the first coin passage 4 and the third coin passage 9 as shown in FIG. Is guided to the fourth coin passage 13 by the second lever 11, and is then dropped from the back of the main controller 2 and stored in a safe (not shown) as shown in FIG.

Next, when the coin groups of coins B and C are introduced from the coin inlet 3 as shown in FIG. 11 with the same reference numerals as in FIG. 1, the coin is recognized by the coin discriminating apparatus 30 of FIG. In addition, since the type of coin is determined to be the coin group of coins B and C, only the drive signal of the first solenoid 40 is sent out by the controller 34. Therefore, the first lever 7 is shown in FIG. As described above, the third coin passage 9 is opened by rotating the predetermined angle clockwise. Furthermore, since the drive signals are not transmitted to the second and third solenoid plungers 41 and 42, the second and third levers 11 and 12 are stopped at the initial positions shown in FIG. .

For this reason, the coins B and C are guided only to the fifth coin passage 14 as shown in FIG. 11 by restricting the traveling direction by the first and second levers 11 and 12. Coins B and C guided to the fifth coin passage 14 are separated and guided to the seventh coin passage 17 by the rail-type coin sorting device 16 shown in FIG. Coin C is separated and guided into the eighth coin passage 18, and each drop is received in the coin dispensing device (not shown) disposed below the coin.

On the other hand, as shown in FIG. 12, when the coin group of coins D and E is introduced from the coin inlet 3, the coin discrimination apparatus 30 of FIG. 7 shows that the coin is a real coin and the coin type is coin D and E. Since it is determined that the group is a group, only the drive signal of the first solenoid plunger 40 and the drive signal of the third solenoid plunger 42 are transmitted by the controller 34, so that the first lever 7 is the tenth. As shown in FIG. 12, the third coin passage 9 is opened by rotating the predetermined angle clockwise, and the third lever 12 rotates the predetermined angle clockwise as shown in FIG. The passage 15 stops at the open position. For this reason, all the coins D and E which transmit the 3rd coin path 9 are guide | induced to the 6th coin path 15 as shown in FIG. The coins D and E guided to the sixth coin passage 15 are guided to the coin passage 22 by the rail-type coin sorter 21 shown in FIG. 5, and the coin E is coined. It is guided to the passage 23 and falls downward, and is accommodated for each type of coin in a coin dispensing device (not shown) disposed below it.

Furthermore, in the above embodiment, the real coins were five kinds of coins of only A, B, C, D, and E having different diameters, but the coins A were stored in a safe (not shown) via the fourth coin passage 13. A should be the maximum amount of coins that can be used.

In addition, the group of coins B and C and the groups of coins D and E are selected by a rail type coin sorting device that selects each using a difference in diameter. Therefore, when the five types of coins are divided into groups, the difference between the diameters of coins B and C It is desirable to select coins and divide them into groups so that the difference between the diameters of the coins and the coins D and E can be as large as possible.

In the above embodiment, the first and second rail type coin sorting devices 16 and 21 are used as the coin sorting device for dividing two kinds of coins by the difference in diameter, but the present invention is not limited to the above embodiments. Instead of the first and second rail type coin sorting devices 16 and 21, a coin sorting device such as a cradle or a carrier arm may be applied.

As described above, in the coin sorting apparatus of the present invention, a total of three solenoid plungers are used to sort out real coins and fake coins, and at the same time, five kinds of real coins having different diameters are selected for each coin type. The number of solenoid plungers used in comparison with this type is greatly reduced, which makes it possible to improve the compact coin sorting device because of its simple structure and low number of parts. In addition, since three solenoid plungers are good, the circuit configuration of the coin discriminating device for driving them is simplified, and maintenance work can be easily performed without expert knowledge.
