  • Patent number: 7128196
    Abstract: An apparatus for assembling an automotive body on an assembly line having a right-hand body subassembly line, a left-hand body subassembly line and an underbody subassembly line, for delivery to a pallet transport system for movement through a body framing subassembly line. The apparatus includes an overhead transport system for transporting automotive components along at least one of the subassembly lines and for conveying the automotive components along a pallet transport system on the body framing subassembly line. The overhead transport system includes a trolley movable along a single overhead rail, a carriage slidably movable relative to the trolley, and a plurality of antler nests. Each antler nest is individually engageable with the carriage. The apparatus also includes a lowerator for transferring components from the overhead transport system to a geometry fixture at a workstation along the subassembly line.

  • Patent number: 6732852
    Abstract: A rotatable frame mounted on a base with trunnions. The frame can support a workpiece on more than one surface and can have workpiece engaging devices such as clamps, locating pins or nesting fixtures on both sides. The engaging devices can be different on different sides of the frame. The frame can be rotated by an electric motor, a pneumatic motor or a hydraulic motor. The frame can be expandable to accommodate frames of different sizes. The workstation can have a plurality of trunnion mounted fixtures positioned next to each other and a robot moveable between the fixtures. The frames can be replaced with a lifting device moving along an overhead rail. The frame includes an aperture positioned along the rotational axis of the frame for communicating power from an external power source to workpiece engaging devices.

  • Patent number: 6564440
    Abstract: An apparatus for assembling multiple automotive body styles on a single assembly line. The apparatus includes a workstation with multiple geometry fixtures, at least one geometry fixture for each automotive body style to be processed at the work station. One geometry fixture is at a ready position of the work station to support an automotive component during a processing operation. The geometry fixtures can be exchanged at the ready position so that a production rate of the assembly line can be maintained. The apparatus also includes a lowerator for transferring an automotive component from an overhead transport system to the geometry fixture at the ready position.
