Abstract: A rolling conveyor has a frame on which a plurality of feed rollers that define a conveyor surface are rotatably supported, at least some of the feed rollers each have a first drive wheel, which is in rotary drive communication with a second drive wheel, the second drive wheels are located on a rotatable drive shaft with which they are each in rotary drive communication via a respective slip clutch, at least one and preferably all the second drive wheels and the associated slip clutch are combined each into a separate drive assembly that can be installed as a unit, the drive assembly is supported rotatably on the frame, and the drive shaft is received in the drive assembly in a manner fixed against relative rotation and preferably longitudinally displaceably.

Abstract: A dual track conveying system for transporting workpiece carriers, has a main conveyor and, an auxiliary conveyor arranged parallel to the main conveyor. At least one transverse conveyor is arranged between the main conveyor and the auxiliary conveyor. The transverse conveyor is pivotally attached to the main conveyor. The moveable end of the transverse conveyor pivots up-and-to transfer the workpiece carriers from the transverse conveyor to the auxiliary conveyor. The transverse conveyor has a short belt and a long belt. The short belt is shorter than the long belt by the width of the auxiliary conveyor. A passive conveying track section following the path of the short belt is located in between the belts of the auxiliary conveyor to support one end of the work piece carrier when the moveable end of the transverse conveyor is in the raised position.

Abstract: Apparatus for displacing workpiece carriers from one conveying path to a further conveying path. The apparatus has a lifting device for the workpiece carrier arranged in a transfer zone with which the workpiece carrier can be transferred from the feeding conveyor path to the further conveyor path. The further conveyor path has at least one transport, where pulling run can be lifted and later lowered from the first place to a second place by the lifting device so that the pulling run of the transport belt can serve as a support for the workpiece carrier. Arranged at the end of a transport section of the further conveyor path in the transport zone, is at least one lifting-deflecting device deflecting a transport belt, which lifting-deflecting device can lift and lower the respective transport belt from the first plane to the second plane substantially by the same amount as the lifting device of the same transport belt.

Abstract: An apparatus for shifting work carriers from a main conveying path (40) to a branching conveying path (45) arranged transversely thereto wherein the. The main conveying path (40) consists of a feeding conveying path (41) and a discharging conveying path (42). The conveying paths (40, 41, 42, 45) are formed from double-belt conveyors, one transport belt (45') of the branching conveying path (45) being arranged between the feeding conveying path (41) and the discharging conveying path (42). The feeding conveying path (41) and the discharging conveying path (42) are arranged with their ends in each case above the plane of the transport belt (45') of the branching conveying path (45).
