The coin is not the missing link in the financial system of a country , almost everywhere in the day-to-day trading applications . It is uniform , easy to identify , easy to wear , prolonged circulation . However, with the development of the times and the progress of science , the coins are also increasingly revealed some problems . The first coins than banknotes weight is too heavy, the larger number is difficult to store and transport ; followed by the processing of a large number of coins is very arduous , time-consuming using manual inventory , its banks to increase inventory costs , direct damage to the general public interests; speculators and a large number of lawbreakers use counterfeit money or play money instead of real money, causing huge losses to the bus companies . The foreign coins processor earlier studies , but the equipment is large and expensive . Although the domestic development of a small coin sorter , Kam pseudo helpless face of counterfeit coins flooding . Therefore, the development and research of the coin Kam pseudo desktop sorter has great significance. The paper first analysis of research on a variety of domestic and foreign coin processing equipment , and the eventual establishment of the overall mechanical system solutions and electronic control system solutions by comparing a variety of sorting principles . Through eddy current sensor , authenticity identification, with the rotational movement of the motor to provide power , the use of photoelectric switches to count and the use of electromagnets for the separation of coins . The use of methods fusion sorting the structure of the advantages of the merger of two similar , to design a new type of sorting institutions . Followed by detailed design of mechanical systems , Kam false principle and electric control system design . CAD theory and the SOLIDWORKS tools for modeling and simulation of the top five agencies , the use of the the DFA theory of the size and angle correct and optimize . Propose a new spiral track layout scheme to reduce the structure size , depositing a new cylinder fixed and remove programs designed to save space , creating a combination of man-machine coin Package . Finally, through an eddy current sensor to test Kam pseudo functions reasonableness and correctness , and summed up the innovation and the problems in order to facilitate for further research .
