Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a coin sorting device, and more particularly to a coin sorting device that discriminates the authenticity of coins with high accuracy.

[Background of the invention]

Conventional coin counters and sorting machines inspect coins by combining their outer diameter, thickness, weight, influence of magnetic field, amount of repulsion upon collision, etc.
The coins are authenticated and sorted.

However, with this sorting means, it is impossible to distinguish foreign coins of the same size and material, or counterfeit or altered coins of the same material. For this reason, in reality, crimes involving vending machines using altered or foreign coins are rapidly increasing.
[Objective of the Invention] The present invention has been made based on the above-mentioned problem, and an object of the present invention is to provide a coin sorting device that can perform highly accurate coin discrimination. .

[Summary of the invention]

The present invention provides an apparatus for sorting coins, which includes a first sorting section that determines authenticity by comparing the vibration frequency of the coin with a pre-stored natural frequency of the coin, and a first sorting section that separates coins from each other. and a second sorting section that sorts the determined true coins by denomination.

[Embodiments of the invention]

Embodiments of the present invention will be described below with reference to the drawings.

The drawing shows an example of the device of the present invention, and in the drawing, I
Fi indicates the coin to be identified. 2 is a first sorting section that determines the authenticity of coins; 3 is a second sorting section that sorts the genuine coins determined by the first sorting section 2 according to denomination; 4 is the first sorting section 2 5a to 5d are guide paths for coins of each denomination sorted by the second sorting section 3.

Describing the detailed configuration of the first sorting section 2 described above, 6 is an input path for coins 1, 7 is a colliding partner member disposed below the input path 6, and 8 is a coin 1 colliding with the colliding partner member 7. a space chamber for freely moving the coins; 9 a gate for switching the coins 1 between the second sorting section 3 and the discharge passage 4;
Reference numeral 10 denotes gate switching means, and reference numeral 11 denotes vibration detection means for detecting the vibration of the coin 1 freely vibrating within the space chamber 8, which can be composed of, for example, a microphone. Reference numeral 12 denotes a discrimination section that compares the vibration frequency of the coin 1 to be discriminated from the vibration detection means 11 with the pre-stored vibration frequencies of each denomination of coin to discriminate its authenticity. When this discrimination section 12 discriminates that the coin 1 to be discriminated is a fake coin, it outputs a gate operation signal to the all gate switching means lO.

The second discrimination section 3 is shown as an example in which coins are sorted by denomination based on the size of the coin.

Next, the operation of an example of the apparatus of the present invention described above will be explained.

Coins 1 to be discriminated are put into the input passage 6 of the first sorting section 2. Guided by this input passage 6, the collision partner member 7
collide with Thereafter, the coin 1 freely vibrates within the space chamber 8 and falls. At this time, the frequency of the coin 1 is determined by the vibration detection means 1
1 is detected and input to the discrimination section 12. Identification part 1
2 compares the detected vibration frequency with the pre-stored unique vibration frequency of each denomination to determine its authenticity. As a result of the determination,
If the coin is a fake coin, the discrimination section 12 outputs a gate operation signal to the gate switching means 10 in order to guide the coin l to the discharge passage 4. As a result, the gate 9 is switched and the fake coins are guided to the discharge passage 4. This discharge connoisseur! f! i
The fake coins guided by the first sorting section 4 include foreign coins and altered coins that have the same dimensions and material as the domestic coins discriminated by the first sorting section 2. In other words, counterfeit coins are eliminated at this stage. On the other hand, the coins determined to be genuine coins by the first sorting section 2 are sorted by each denomination by the second sorting section 3, and are stored in the respective safes through the respective guide passages 5a to 5d.

In the above-described embodiment, the second sorting section 3 is of the size-based sorting type, but it is also possible to use a sorting type of sorting type based on weight or the influence of magnetic yang.

〔Effect of the invention〕

As described above, the present invention eliminates counterfeit coins such as foreign coins and altered coins in the first step, and sorts only genuine coins by denomination in the second step, allowing for highly reliable identification. In addition, it is possible to simplify the mechanism for removing counterfeit coins.

[Brief explanation of the drawing]

The drawing is a diagram showing the configuration of an example of the device of the present invention.
