A system for transporting work pieces, preferably in the garment industry, includes a main conveyor 101 and a number of branch conveyors 1 each forming a loop from the main conveyor through a working station and back to the main conveyor. The main conveyor is provided with a pinion driver continuous corrugated belt running around a track and carrying dogs to force carriers 2 for the work pieces to move around the track. The branch conveyors are each provided with a downwardly sloping section 132 to let the carriers move from the main conveyor to the work station by means of gravity. From the working station the carriers 2 are moved back up to the main conveyor by means of a discontinuous drive comprising a piston-and-cylinder device reciprocating a chain carrying detents which engage and propel the carriers on the drive stroke of the device but pivot so as not to entrain the carriers on the return stroke of the device. The carriers may be equipped with address elements which cooperate mechanically with sensing and track-setting apparatus to automatically route the carriers. <IMAGE> |
