Abstract
A divider switch for a roller conveyor selectively switches or displaces the lateral position of objects being conveyed to either separate or merge the objects. The switching apparatus is interposed in a live conveyor system. The divider switch includes a framework of longitudinal and transverse members; a plurality of transverse rollers at either end of the switch; a set of angularly movable rollers centrally located in the switch, the angularly movable rollers being of shorter length than the transverse rollers and switchable between at least two angular positions which define opposite acute angles relative to the transverse rollers; and two additional sets of rollers disposed on opposite sides of the angularly movable rollers, the additional sets of rollers being fixedly mounted to define opposite acute angles relative to the transverse rollers. A pivoting parallelogram frame and an actuating device, which may automatically respond to the objects, shift the angularly movable rollers between angular positions.
