Dynamic Analysis on the Paper Sheet Separated by the Overlap Separation Mechanism
Department of Mechanics, Tianjin University
The working principle of overlap separation mechanism is introduced. The dynamic equations of paper passing through the overlap separation mechanism are established by using the modified Coulomb friction model. The change of paper deformation force with time is considered in the process of paper passing through the overlap separating mechanism. The numerical simulation is carried out by using the software of matlab. The influence factors of overlap separating mechanism on paper separating are analyzed. The results show that: With the increase of overlap amount, torque and friction coefficient of separating wheel, the single note passing through the separation mechanism spends more time, while double notes feeds, the restraining effect of the sticking note is strengthened, which is convenient for separating bills; for separating effect, the influence of separating wheel torque is small.
