Abstract
An accumulator conveyor having a load support frame defined by side rails each having a series of idler wheels, the load support frame defining a load support plane adapted to support a series of loads along its length. A shuttle frame is reciprocable relative to, and preferably supported by, the load support frame. The shuttle frame carries a series of pusher bars spaced one from the other to define a series of load stations along the conveyor's length. A novel drive mechanism reciprocates the shuttle frame, and therefor the pusher bar assemblies, relative to the stationary load support frame, for indexing any load on the load support frame from an upstream station to an adjacent downstream station. The conveyor also includes a novel station lock out system which causes the pusher bar of a station to be latched down beneath the support plane of the load in that station when loads are parked in all stations downstream therefrom. And further, the station lock out system includes novel structure which permits any one or more pusher bars to be latched down substantially beneath the load support plane if the load parked in any one station has a bottom surface that is deformed beneath that load support plane.
