Coin separating, counting and identifying device and method

Abstract

The invention discloses a coin separating, counting and identifying device and method. The device comprises a funnel (1), a rotating disc (2), a base (3), a motor (4), a baffle plate (5), electromagnetic valves (6), photoelectric sensor detection holes (7), electromagnetic valves, Hall sensors, a permanent magnet and a single-chip microcomputer. The funnel (1) is provided with an opening which is used for putting coins. The funnel (1) is connected with the base (3) and arranged on the upper surface of the base (3). The rotating disc (2) is arranged on the base (3) and positioned between the funnel (1) and the base (3). The rotating disc (2) is provided with the photoelectric detection holes used for the sensors. The motor (4) is arranged on the lower surface of the base (3) and connected with the rotating disc (2) and used for driving the rotating disc (2) to rotate. The emission electrodes of the photoelectric sensors (7) are fixed on the upper surface of the rotating disc (2), and the receiving electrodes are fixed on the lower surface of the rotating disc (2) and arranged at the position exactly facing the emission electrodes. Automatic counting and separating of the coins and authenticity identifying of the coins can be realized by the coin separating, counting and identifying device and method.

Description

technical field [0001] The invention relates to the separation, counting and discrimination of the fifth set of coins, which applies sensor technology and belongs to the field of electromechanical control. Background technique [0002] At present, coins still have great use value in our country and are widely used in places such as transportation and banks. At present, there are three different denomination coins of one dime, five jiao and one yuan in circulation in the market, mainly the fifth coin issued in 2005. Set of coins. In bus companies, banks, supermarkets and other places where a large number of coins are concentrated, the separation of coins of different denominations and counterfeit coins is a big problem. The traditional manual separation method is time-consuming and laborious, which is not in line with the development trend of modern society; there are also a type of coins on the market Separators, but most of them only have a single function, such as simple ...

Problems solved by technology

In bus companies, banks, supermarkets and other places where a large number of coins are concentrated, the separation of coins of different denominations and counterfeit coins is a big problem. The traditional manual separation method is time-consuming and laborious, which is not in line with the development trend of modern society; there are also a type of coins on the market Separators, but most of them only have a single function, such as simple coin separation, this type of machine is purely mechanical, and is driven by a motor, which drives the vibrating table to vibrate at high frequency continuously, and the vibration makes the coins move slowly to the edge of the vibrating table , There are coin-sized holes on the edge of the vibrating table, so different coins will fall into the hole channels of different sizes, and the coins are separated. Obviously, there are many problems and shortcomings in this type of separator.

[0003] Investigations and studies have found that most of the existing coin separators have one or more of the following disadvantages: (1) they can only separate various coins, and it is difficult to count and distinguish counterfeit coins (coins imitated with different materials, game coins); (2) Most of them adopt the principle of vibration separation, purely mechanical separation, serious noise pollution, expensive and not energy-saving and environmentally friendly; (3) The separation accuracy is low and the efficiency is low

(4) Large size, heavy weight, short service life, complicated disassembly and assembly, and difficult maintenance
