Abstract

A conveyorized transport system which can be used to transport workpieces to a series of subsidiary loops, comprises a main rail, workpiece carrying trolleys movable on the main rail, a subsidiary loop adjacent to the main rail which leads to a work station, a special switch to transfer a trolley between the main rail and the subsidiary loop, and a computer to track and control the movement of the workpieces. The main rail and the subsidiary loop each have a gap laterally spaced from one another, and each switch includes a transfer rail section which can be moved laterally between the gap in the main rail and the gap in the subsidiary loop to transfer a trolley between the main rail and the subsidiary loop. One specific embodiment of the transport system also includes a chain-driven pusher extending downward from an overhead track which drives said trolley while it is being transferred between the main rail and the subsidiary loop.
