The feeding mechanism for piled sheets, such as in an ATM, handles paper that has uneven thickness due to printing conditions, watermarks and other factors. When these sheets are piled in the same direction, the tops of these sheets often lean. Because leaning sheets cannot contact the rollers of the feeding mechanism properly, they often skew. Excessively skewed sheets cannot be correctly recognized, and sheet jamming occurs. We studied the pressure characteristics of the feeding rollers to reduce skewing. Using FEM analysis, we designed rollers that have different configurations, and then developed a feeding mechanism that has these rollers. The experimental results showed that the rollers we proposed here can reduce sheet skewing.
