Abstract
The apparatus for conveying plate-like parts, especially circuit boards, of varying thickness, comprises an upper roller and an associated lower roller between which the plate-like objects are fed, and a gear-tooth system, connecting the lower roller with the upper roller, by which the lower roller drives the upper roller. So that the apparatus operates optimally even with substantially thicker than usual objects, the gear-tooth system is structured to maintain a constant axial spacing between the lower roller and the upper roller. The upper roller with its gear teeth is mounted with an upper roller bearing in a circular arc-shaped coulisse, and the arc center point of the circular arc-shaped coulisse is positioned at a bearing center point for the lower roller, so that the radius of the circular arc-shaped coulisse corresponds to the axial spacing of the gear system. A method for conveying plate-like parts of varying thickness is also described.
