Abstract
Sheet separating mechanisms are used in ATMs (automated teller machines) to separate bank notes. These mechanisms are composed of separate-gate-rollers. Sheets are separated when the overlap distance of the separate-gate-rollers is appropriate. We have found out by experiment that although the appropriate overlap distance range differs according to the configuration of the separate-gate-roller, the range of friction force between a bank note and the separate-gate-roller is equally 3 to 10N. Thus, we have examined a method to estimate the friction force by numerical analysis, using the ABAQUS nonlinear structural analysis program. Consequently, calculated friction forces were found to correspond to experimental friction forces quantitatively and qualitatively.
