Abstract
Predicting the behavior of sheets with a high degree of reliability is important when designing sheet-handling machinery. Automated teller machines, in particular, require the deformation of each bill in the feeding mechanism to be analyzed to predict the reliability of the mechanism. We, therefore, developed a simulation method that can predict the behavior of sheets in an overlap-type sheet separating mechanism under various conditions by means of a finite element method. To predict the reliability of its mechanism, we also analyzed deformation forces by means of Clapeyron's theorem. We derived a formula that showed the relationship between the deformation forces and coefficients of friction of the rollers in its mechanism, which is useful when designing the sheet separating mechanism.
