Abstract
A slat sorter comprises a main line conveyor with a transport surface on which pusher elements are mounted. The main conveyor is driven by a bearing chain that cooperates with a sprocket that is in turn driven by an electric motor. The pusher elements are selectively diverted by a divert switch from forward travel in a straight-through mode to diagonal travel across the transport surface in a divert mode to engage and direct articles to a takeaway conveyor. The divert switch comprises a switch arm that is positively actuated to both a home position for straight-through mode and a divert position for divert mode by a brushless torque actuator that generates rotary driving operation, but without linear-to-rotary motion conversion. A crossover switch is provided to guide the pusher elements in the proper diagonal path. A gate is driven to pivot between limit positions by a brushless torque actuator to facilitate unobstructed pusher element travel along the desired diagonal path.
