  • Patent number: 6430837
    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.

  • Patent number: 6415910
    Abstract: A forward feed device for conveyor tables includes a drive element (38) that can be moved to and fro, which moves out of the table area (36) during the forward movement and back underneath it during the return movement. The drive element comprises a pivotable latch (38) that can be moved upwards out of the table area in the forward feed direction, of which the end that leads and can be raised during the forward feed movement is supported, via a link (48) with two pivoting ends, by a friction block (54) that trails behind during the forward feed movement and the return movement, and that is slowed down by friction against a stationary surface.

  • Patent number: 6389981
    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.

  • Patent number: 6371281
    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.
