Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a coin sorting device used for a vending machine, a money changer, a service device and the like.

[0002]

[Prior art]

 Generally, a coin sorter is installed in devices such as a vending machine, a money changer, and a service device, which sorts input coins into genuine coins and counterfeit coins, and sorts genuine coins into denominations.

Further, in the coin sorting device described above in recent years, as a coin discriminating means for discriminating the authenticity of the input coin and the denomination of the genuine coin, an oscillation and reception coil arranged facing each other at a predetermined interval is provided. Electronic coin discriminating means using a coil sensor consisting of is used.

[0004] The authenticity of the inserted coin and the denomination of the authentic coin are determined based on the oscillation of the coil sensor described above and the change in the frequency or the like detected when passing between the receiving coils. Has been done.

[0005]

[Problems to be solved by the device]

 By the way, in the coin sorting device using the electronic coin discriminating means including the coil sensor described above, the discriminative factors such as the material, size and weight of the coin are compared with those of the genuine coin to discriminate the authenticity of the coin. Rather than discriminating the authenticity of the inserted coin based on the change in the frequency detected when passing between the oscillation and the receiving coils, even if the coin is completely different in material, size and weight, , If the change in the frequency detected while passing between the oscillation coil and the receiving coil happens to be at the same level as the true coin, the coil sensor may mistakenly recognize it as a true coin. However, the tendency of misidentification is remarkable in the case of a coin having a weight smaller than the minimum weight of the coins handled by the coin selecting device.

In view of the above-mentioned circumstances, the present invention has a coil sensor that determines, when a coin having a weight smaller than the minimum weight of coins to be handled is inserted, whether the coin is true or false. It is an object of the present invention to provide a coin sorting device that prevents the passage of coins.

[0007]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, in the present invention, a coil sensor is arranged to discriminate between coins passing through the first coin passage communicating directly with the coin slot and discriminating between genuine and false coins and denominations of genuine coins. In a coin sorting device configured to guide to a second coin passage, in the first coin passage, the first coin passage is always elastically closed, and a weight of a minimum weight of coins to be handled or more When the coin is inserted, the first coin passage is expanded by its weight to allow the passage of coins, and when a coin with a weight smaller than the minimum weight of the coins to be handled is inserted. An elastic tongue is provided to keep the first coin passage closed and prevent the passage of the coin.

[0008]

[Action]

 According to such a coin sorting device, a coin having a weight smaller than the minimum weight of the coins to be handled among the coins inserted from the coin insertion slot is moved in the first coin passage by the resilient force of the tongue piece. Therefore, a coin with a small weight is not injected into the second coin passage and does not pass through the coil sensor.

【Example】

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

FIG. 2 is a partially cutaway front view of the coin sorting device according to the present invention.

The coin sorting device 1 includes a main plate 2 formed of a hard polymer material, a gate plate 3 that can be opened and closed to cover an upper front portion of the main plate 2, and a lower front portion of the main plate 2. It is composed of a front cover 4 and the like for covering.

Of these, a coin slot D is formed between the upper portion of the main plate 2 and the gate plate 3, and the coin slot D is formed substantially vertically below the coin slot D. A first coin passage 5 is formed which directly communicates with the coin and which allows the coin inserted from the coin insertion port D to be vertically downward.

Further, at the lower end of the first coin passage 5 and between the upper side of the front surface of the main plate 2 and the gate plate 3, coins falling from the first coin passage 5 are shown in the right direction of the drawing. An inclined second coin passage 6 for rolling is formed. The second coin passage 6 is composed of a gate rail 7 made of metal or the like. In the middle of the second coin passage 6, the inserted coins are genuine and false, and coins regarded as genuine coins. A coil sensor 8 including an oscillating and receiving coil (not shown) for discriminating the denomination is provided. It is needless to say that the oscillation and reception coils are arranged at intervals of about one coin in order to pass the inserted coin.

On the other hand, below the end of the second coin passage 6, that is, between the lower front portion of the main plate 2 and the front cover 4, the coins jammed between the main plate 2 and the gate plate 3 are discharged. A slug chute, a coin sorting device that sorts the inserted coins according to the detection value of the coil sensor 8 for each denomination, and a coin sorting device including a solenoid (not shown), and a plurality of coin passages that guide the sorted coins for each denomination. Etc. are formed.

On the other hand, on one side wall 5a side of the first coin passage 5, as shown in FIG. 1 and a sectional view taken along the line AA of FIG. 2 and FIG. 1, there is an elasticity that constantly elastically closes the first coin passage 5. A tongue 10 of the body is arranged.

The tongue piece 10 is made of synthetic resin such as Mylar, and the upper end 10a thereof is attached to the slope 11a of the stopper bracket 11 which is fitted to the peripheral edge of the coin slot D and is detachably mounted. It is attached via an agent or the like. Further, the free end 10b which is the lower end thereof is pressed against the other side wall 5b of the second coin passage 5 with a predetermined elastic force as shown in FIG. It should be noted that the elastic force of the tongue piece 10 depends on the weight of the coin when the coin having a weight equal to or more than the minimum weight of the coins handled by the coin sorting device 1 is inserted through the coin insertion port D. When the coin passage 5 is expanded and a coin with a weight smaller than the minimum weight of the coins to be handled is inserted, the first coin passage 5 is kept closed and the passage of the coin is blocked. Is set.

Reference numeral 9 in FIG. 1 is a slag chute that is formed in the front cover 4 and discharges coins that are jammed between the main plate 2 and the gate plate 3.

Next, the operation of the above-described tongue piece 10 will be described and the configuration will be described in more detail.

As shown in FIG. 3 in which the same parts as those in FIG. 1 are indicated by the same reference numerals, a coin B having a weight equal to or more than the minimum weight of coins handled by the coin sorting device 1 is thrown from the coin slot D as shown by a dashed line. When inserted, the coin B bends the free end 10b of the tongue piece 10 in the clockwise direction against its resilience due to its weight, so that the first coin passage 5 is released and the coin B is It passes through the coin passage 1. Then, when this coin B passes through the first coin passage 5, next, as shown by the arrow in FIG. 4, in which the same parts as those in FIG. Along the right side of the drawing, the coil passes through the coil sensor 8, and the authenticity of the coin B and its denomination are determined during the passage.

On the other hand, as shown in FIG. 5 in which the same parts as those in FIG. 1 are indicated by the same reference numerals, a coin C having a weight smaller than the minimum weight of coins handled by the coin sorting device 1 is indicated by a chain line from the coin slot D. , The coin C tries to bend the free end 10b of the tongue piece 10 in the clockwise direction against its elastic force by its own weight. In this case, the elastic force of the tongue piece 10 is increased. Is set to be stronger, the coin C is clamped between the other side surface 5b of the first coin passage 5 and the free end 10b of the tongue piece 10, and its progress is stopped.

In this case, if a gate lever (not shown) is operated and the gate plate 3 is released to the right as shown by the arrow in FIG. 5, the other side surface 5b of the first coin passage 5 and the tongue piece 10 are released. The coin C sandwiched between the free end 10b and the free end 10b is returned to a coin return port (not shown) via the slug chute 9 formed below the first coin passage 5. Therefore, according to the coin sorting device 1 described above, when the coin C having a smaller weight than the minimum weight of the coins to be handled is thrown into the coin slot D, it is returned to the coin return slot via the slag chute 9. Therefore, since the coin C does not pass through the coil sensor 8 through the second coin passage 6 shown in FIG. 2, mistakes made by the coil sensor 8 in determining whether the coin is correct or false and the denomination are reduced as much as possible. It will be.

It should be noted that recently, in order to prevent the liquid material from flowing to the second coin passage 6 side against the mischief that pours the liquid material such as detergent from the coin slot D, the same as in FIG. As shown in FIG. 6 in which parts are designated by the same reference numerals, a plurality of liquid guide grooves 20 for guiding the liquid (arrow) injected from the coin insertion port D further downward along the first coin passage 5 are provided. , The main plate 2 and the gate plate 3 forming the both side walls of the first coin passage 5 are respectively formed, and the liquid flowing along the guide groove 20 is formed in the main portion under the first coin passage 5. There is one in which after collecting by a liquid material collecting section (not shown) formed on the plate 2, the collected liquid material is quickly discharged to the outside of the coin sorting device 1 through a tube or the like.

In the coin sorting apparatus 1 having such a liquid discharging means, when the above-mentioned tongue piece 10 is simply disposed in the first coin passage 5, the surface of the tongue piece 10 causes the coin insertion slot to be opened. The liquid poured from D may not flow along the guide groove 20, so in this case, as shown in FIG. 7 in which the same parts as those in FIGS. A plurality of elongated holes 10c may be formed along the guide groove 20 of the liquid, and the liquid flowing on the surface of the tongue 10 may be guided into the guide groove 20 through the elongated hole 10c.

In the above embodiment, the tongue piece 10 is attached to the peripheral edge of the coin slot D via the stopper bracket 11 which can be fitted freely. Therefore, if the tongue piece 10 is prepared as an option, it is conventional. It is possible to easily attach the tongue piece 10 without changing the design of the coin sorting device.

Further, in the above-mentioned embodiment, the tongue piece 11 is attached to the stopper bracket 11, but the invention is not limited to the above-mentioned embodiment, and the upper end of the tongue piece 10 is bonded via an adhesive or the like. 10a may be directly attached to one side surface of the first coin passage 5 and disposed.

[Effect of device]

 As described above, in the coin sorting device of the present invention, the elastic tongue piece is arranged in the first coin passage immediately after the coin insertion slot, and the tongue piece allows the weight of the coin to be handled to be at least the minimum weight. When a coin is inserted, the first coin passage is expanded by its weight to allow passage of coins, and when a coin with a weight smaller than the minimum weight of the coins is inserted. Since the blockage of the first coin passage is maintained to prevent passage of that coin, when a coin with a weight smaller than the minimum weight of the coins to be handled is inserted, the coin becomes the first coin. Therefore, the coin does not pass through the second coin passage in which the coil sensor is installed, and therefore the coil sensor may misidentify the coin as genuine. Can be reduced to
