The present invention relates to selecting and counting normal coins and defective coins in the coin put, and more particularly, in the process of sorting the coins put therein, by detecting the material and size of each coin to detect the bad coins and normal coins at high speed. The present invention relates to a coin sorting / counting device capable of accurately sorting and counting.

Generally, various types of coins are used in transportation, vending machines, coin exchangers, service machines and game machines in other countries of the world, that is, in Korea, 10, 50, 100 and Coins of different diameters are used, such as 500 won, and various types of coins having different diameters are used for dollars (USD) and euros (EUR).

In addition, in the present application, the scope of the coin includes a token used for transportation as well as a currency unit, and a game chip used for a game machine or the like. Coins of the modified form in the specified coin will be described as a bad coin.

In this way, the sorting means for selecting normal coins, bad coins, and similar coins in the various types of coins used in the various types of coins having different diameters are essentially used. .

As described above, a conventional coin sorting means used in various types of apparatus has been screened by a coin-type sorting device for sorting according to the weight of coins put in, that is, putting coins one by one. Regardless of size and material, only the weight of the coin is measured and sorted. In this sorting device, when the same weight as the weight of the coin is measured, the normal coin is separated, so that the defective coin or foreign matter is sorted out correctly. I had a problem that I could not do.

Accordingly, although a sorting means for measuring and selecting the material or size of the coin has been conventionally provided, the method of measuring only the electronic material is normal when the metal material is added, rather than the coin having the same material as the coin. Judging by the coin, it had a problem of separating it into a normal coin.In case of measuring only the latter size, regardless of the material, if the size measurement of the same size as the corresponding coin was made, it was separated into a normal coin. Coin or foreign matter was not selected correctly had the problem.

Referring to the conventional representative coin sorting apparatus 100 used as described above in more detail with reference to FIG.

As shown in the lower portion of the input hopper 110 is provided with a rotating plate 120 that is rotated by the motor (M) drive, the coin injected onto the rotating plate through the input hopper is the input hopper due to the centrifugal force by the motor drive It is located toward the outlet 115 formed on one side between the 110 and the rotating plate 120, the coin located on the outlet side is pulled out belt 130 connected to a plurality of pulleys rotated by one transfer motor (M1) At the same time as the transfer through the belt 132 and measuring the material or size only by the sensor (S) measuring only one of the material and the size was selected as normal coins and bad coins.

However, the conventional coin sorting device has a problem that the coin is not discharged smoothly as it is configured to be discharged by the centrifugal force by the rotation of the rotating plate in the process of the coin injected into the hopper discharge.

In addition, when the defective coin or foreign matter is introduced into the input hopper, there was also a cumbersome problem of removing the defective coin or foreign matter separately by the manual operation of the operator by stopping the entire sorting device.

Above all, the above-described conventional sorting device has not solved the problem of detecting and sorting only one of two materials or sizes, which are characteristics of coins in various forms.

In the prior art, in the case of the magnetic sensor in the sensor, the analogue signal was detected by changing the material and size of the magnetic field. However, in the case of the magnetic sensor that detects the analogue signal by the change of the magnetic field, temperature change or humidity is detected. The change of the intensity of the analog signal caused by the change did not allow the normal measurement and the problem of not correctly selecting normal coins and bad coins.

Accordingly, the present invention has been made to solve the conventional problems as described above, the object is to detect and separate the coin and normal coin at high speed accurately by detecting the material and size of each coin in the process of sorting the input coins And counting.

Another object of the present invention is to facilitate the discharge of defective coins or foreign matter in the coin supply unit.

Another object of the present invention is to allow the transfer of coins to be made more quickly.

Still another object of the present invention is to minimize the flow of coins in the process of conveying.

The present invention for achieving the above object, in the device for sorting and counting each coin in a large amount of coins and normal coins, each of the coins put in one side of the main body housing discharged by rotating one by one A coin supply unit formed to allow; Transfer means for transferring the coins formed in the discharge port of the coin supply unit by the elastic force; A transfer path connected to the discharge portion of the coin supply unit and formed on an upper surface of the main body housing so that the coin is transferred by a transfer unit; Sensing means for sensing and counting the material and size of the coin being provided on the transport path; A normal coin accommodating part and a defective coin accommodating hole provided on the transfer path by a sensing signal of the sensing means; It characterized in that it comprises a control means for controlling the coin supply unit, the sensing means and the normal coin storage unit interlocked with each other.

In the above, the normal coin storage unit and the defective coin storage hole is provided with a conventional holder (not shown) in which each normal coin or defective coin can be stored.

In addition, the control means is connected to the normal display means that can display the amount of the normal coins counted in the normal coin receiving unit, the method of sensing the material is analog signal type by measuring the change in the magnetic field As the method of sensing size is detected as a digital signal along with a conveying means for conveying coins by elastic force, the analog signal has a weak condition according to temperature or humidity change. The control means judges the digital signal first rather than the analog signal.

Coin introduced into the coin supply unit as described above is discharged one by one through the discharge port, the coin is injected by the rotation, the discharged coin is quickly on the transfer path by the conveying means for transferring the coin by the elastic force to the outlet side In the process of quickly moving coins on the transfer path, the material and size of each coin carried by the sensing means composed of a magnetic sensor and a photo sensor are detected as well as the detection of the change of a normal magnetic field. Coefficients up to the amount of coins that have been coined are made together.

Accordingly, the signal sensed by the sensing means of the material and size of each coin to be transferred is transmitted to the control means to compare and judge the normal coin data input to the control means. It is to be accommodated in the coin storage unit, when it is determined that the defective coin is to be accommodated in the defective coin storage hole.

In addition, the coins stored in the normal coin storage unit, the material and the size is detected by the detection signal input to the control means by the control means compared with the data of the amount of money determined by the material and size made together with the coefficient By losing, the amount of coins stored as normal coins will be known.

Therefore, the material, size, and coefficient, which are the characteristics of each coin, are sensed together by the sensing means in the process of being transported in the transport path, so that the normal coins and the bad coins can be detected and sorted and counted. It will have the conditions to increase as much as possible, as well as to easily know the amount of normal coins stored.

The coin supply unit 10 has an input hopper 15 provided with an input sensor 13 for transmitting a detection signal to the control means under the detection of whether the coin is inserted into the input port 12 side, the lower portion is provided in the control means The disk 17 is formed by a plurality of receiving grooves (17a) that is accommodated by each one of the coins to be inserted into the upper surface while being rotated by a drive source 16, such as a conventional motor driven by the detection signal of the input sensor by Is formed, it is preferable that the discharge port 11 is formed to be formed in the transport path between the input hopper and the disk.

Accordingly, when the control means receives a sensing signal in which the coin is input by the input sensor on the inlet side, the drive is driven to rotate the disc, and the coin is inserted into the receiving groove formed on the upper surface of the disc during the rotation of the disc. After being inserted, it is ejected while rotating the coin from the outlet by rotation.

Into the input hopper 15 to discharge the bad coin or foreign matter on one side, that is, the foreign matter or bad coin not discharged because it is not inserted into the receiving groove of the disk is operated by the control means (C) after a certain time It is preferable to open the opening and closing door 15b which is opened and closed by the operation member 15a such as a solenoid or a cylinder so as to discharge defective coins or foreign substances.

In the above, the opening and closing door is configured such that one side of the hopper is divided so that the divided ends can be hinged to each other and opened and closed, the divided opening and closing door is opened and closed by the operation of the operating member.

Accordingly, foreign matters or defective coins which are put into the coin supply unit and are not discharged through the discharge port are discharged to the outside through the opening part of the opening / closing door by the operation member operated by the control signal of the control means.
