Abstract
A conveyor apparatus particularly for intra-plant conveyance in the garment industry comprises conveyor tracks, carrier units travelling on the conveyor tracks and having each at least one stirrup member straddling a conveyor track from below and provided with rollers resting on the top surface of the track, and at least one drive unit for actively conveying the carrier units. The drive unit comprises a conveying bar actuatable to reciprocate along a track section and carrying a plurality of drive transmitting members for engagement with the carrier units. The drive transmitting members are mounted so that they are operative to convey in one working stroke direction, while being able to pass said carrier units without engagement therewith in the return stroke direction. The drive transmitting members are adjustable to reverse the conveying direction of the working stroke. Each drive transmitting member, in the form of a pawl, is pivotally attached to the conveying bar, and its pivotal movement in one direction is limited by engagement with a stop, while pivotal movement in the opposite direction is permitted against a resilient biasing force.
