Abstract
Abstract A sorting switch comprises a plurality of channel-shaped pallet support members mounted on drive chains for movement around a course including an upper article sorting portion and a lower return portion. The upper article sorting portion of the course includes parallel article conveying paths, and the pallet support members extend across both article conveying paths. A pallet is slidably supported on each pallet support member and has a switch engaging member depending therefrom. The pallets are arranged in sets, with alternate sets of pallets being normally aligned with opposite article conveying paths. Switching mechanisms are provided for selectively allowing each set of pallets to remain aligned with the article conveying path normal thereto or for diverting the pallets comprising the sets into alignment with the opposite article conveying path. Each switching mechanism includes a stationary input channel for receiving the switch engaging members of the pallets normally aligned with a particular path, a switching channel supported for pivotal movement to receive the switch engaging members from the input channel and to selectively direct the switch engaging members and the pallets connected thereto either to the normal article conveying path or to the opposite article conveying path, and camming structure for receiving the switch engaging members from the switching channel and for either directing the channel members and the pallets connected thereto along the normal article conveying path or for diverting the switch engaging members and the pallets connected thereto into alignment with the opposite article conveying path. Camming structure is also provided on the return portion of the course for returning all of the pallets to their normal orientation with respect to the course.
