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.

A divider switch adapted for use in a roller conveyor system for selectively displacing the lateral position of an object being conveyed thereacross, said divider switch comprising: framework means including a pair of spaced apart and generally parallel longitudinal members and a plurality of transverse members disposed therebetween; angularly movable switching means including a set of centrally located and angularly movable rollers, the longitudinal axis of each of the rollers being in generally parallel relation to axes of other rollers in the set, said rollers being of equal axial length and of substantially shorter axial length than said transverse members and being disposed at a generally central location between said pair of longitudinal members, said rollers also having sufficient axial length to control movement of said object in a direction normal to the axes of said rollers; means for supporting said centrally located rollers, said supporting means freely movable between at least two positions thereby causing the longitudinal axes of said rollers to be oriented at different angular positions in relation to the transverse members of said framework means; actuating means for selectively moving said supporting means between said at least two positions to cause movement of said set of rollers between said different angular positions; two additional sets of rollers with the rollers in each set being of equal axial length, a first additional set of rollers being located alongside said set of centrally located rollers between said set of centrally located rollers and one of said pair of longitudinal members, and a second set of additional rollers being located along an opposite side of said set of centrally located rollers between said set of centrally located rollers and another of said pair of longitudinal members, said additional sets of rollers being fixedly oriented at opposite acute angles in relation to the transverse members of said framework means; and drive means operatively connected with said centrally located rollers and said additional sets of rollers for driving said rollers with the same rotative movement; said additional sets of rollers and said set of centrally located rollers defining a common substantially coplanar conveying surface; whereby said set of centrally located rollers may be selectively moved to a different angular position upon a leading object having laterally moved sufficiently upon one of said additional sets of rollers to cause a succeeding object to be conveyed in a different path across the divider switch before the leading object has been conveyed across said one of the additional sets of rollers and off of said divider switch.
