Idler roller conveyor system

摘要

An idler roller conveyor uses paired rollers set at an acute angle to each other with the rollers being coplanar and skewed toward opposite sides of a perpendicular to a longitudinal axis of the conveyor. Roller pairs are preferably mounted in sub-frames that pivot about on an axis transverse to the conveyor's longitudinal axis. This arrangement produces opposing transverse forces that are subtractive to result in negligible resultant transverse forces that are unlikely to make an object veer off course.

1. A conveyor system having a longitudinal axis oriented in an intended direction of travel of a transported object, and idler rollers being mounted to cross the longitudinal axis, the system comprising:
the idler rollers including a pair of rollers having axes that are coplanar, non-parallel, acutely angled to each other, and are skewed toward opposite sides of a perpendicular of the longitudinal axis; the longitudinal axis being aligned with respect to the intended direction of travel to within +/−½ of the acute angle between the skewed rollers; and the skewing of the roller pair is arranged to reduce the resultant transverse forces on objects being fed along the conveyor system.
