Dynamic analysis and simulation research on speed and stability of banknote feeding mechanism in cash-counting machine

The blocking phenomenon of cash-counting machine is the main factor to affect the counting speed. The similar phenomenon also exists in the automatic teller machine,fax machine,printing machine and other media delivery systems. In order to solve this problem,taking the paper money feeding mechanism of HT-9000 A type currency-counting machine as the research object,the dynamic behavior of the paper money feeding mechanism is simulated and analyzed. By using multi-body system dynamics simulation software Recur Dyn,based on the geometric model of currency-counting machine's transmission mechanism,the contact force between paper money and money entwisting wheel is analyzed. The results show that the money feeding angle range of 11.5°~12.5° can make the notes move in the ideal trajectory,make the machine keep stable note feeding speed,and make the occurrence probability of the blocking phenomenon reduced.
