説明

Both feed and separation process of a separation roller type feed system in printers are simulated by FEM software MARC. The feed system is composed of a feed roller rotating at a constant velocity and a separation roller with reverse torque. In the simulation, a modified Coulomb friction modeos used, where the friction force is a function of slipping velocity as well as vertical load and coefficient of friction. The results show that the feed and separation processes are successfully simulated. The paper feed velocity decreases and separation of two papers increase as the reverse torque becomes larger. The friction forces acting between two papers and rollers are almost the same in magnitude and equal the value obtained by dividing the reverse torque by the separation roller radius. The simple equations predicting the paper velocities are presented.
