Abstract: A positioning conveyor for horizontally aligning panels, metal sheets and the like, with a conveying table, which is provided with driving arrangement, and at least one stop (10, 14) at an edge of the conveying table, has a thickness measuring device (22, 24, 54), which is provided at the stop for measuring the panel thickness of the contacting panels, metal sheets, or like.

Abstract: A conveyor device for position-precisely moving objects on a conveyor surface of the conveyor belt includes a plurality of forward feed elements (42) for taking hold of the objects by their rear bottom edge in relation to the forward direction. Tension members (32) which are endless or connected to an endless strand via the forward feed elements are provided for the purpose of moving the forward feed elements, and the tension members for moving the forward feed elements into a specified starting position can be driven by means of a common shaft (30) to be coupled separately with the tension members. When the forward feed elements are in the specified starting position, the tension members can be uncoupled from the common shaft (30) and each coupled with a separate linear drive (48,50) with the stroke of the desired length of displacement of the objects.

Abstract: A trolley for track systems with essentially right-angled intersections is equipped with raisable and lowerable rollers which can be lowered to engage with, and raised to disengage with, one of the pairs of tracks. A common actuator (76,78) simultaneously lowers, in relation to the trolley, the rollers associated with one pair of tracks and raises the rollers associated with the intersecting pair of tracks.
