Abstract
Multiple workpieces at various stages of manufacture are simultaneously transported, aligned, and processed along the assembly line. Separate workpiece transports are provided for a corresponding number of workstations that perform manufacturing operations on the workpieces. The workpiece transports are capable of movement in the X,Y and Z coordinate directions and can provide rotation in the X-Y plane. The workpiece transports are capable of movement in the X,Y and Z coordinate directions and can provide rotation in the X-Y plane. A workpiece removal component removes a finished workpiece to a storage or stacking area. The device may be used to manufacture either all left, all right, or both left and right version of the workpiece.
Claims8
An apparatus for simultaneously transporting and positioning multiple workpieces on a work surface at different manufacturing workstations, comprising:
- a first workpiece transport means capable of engaging a workpiece against said work surface, said transport means capable of three dimensional coordinate movement and 360.degree. rotation of the workpiece in the X-Y plane upon said work surface;
- and
- a second workpiece transport means capable of engaging an additional workpiece against said work surface, said second transport means capable of three-dimensional coordinate movement and 360.degree. rotation of the workpiece in the X-Y plane upon said work surface, said transport means traveling simultaneously with said first workpiece transport means in a common coordinate direction.
A process for simultaneously transporting and positioning multiple workpieces on a work surface at different manufacturing work stations, comprising the steps of:
- simultaneously engaging against said work surface, by use of a plurality of transport mechanisms capable of three-dimensional coordinate movement and 360.degree. rotation in the X-Y plane of said work surface, a prealigned, blank workpiece and one or more workpieces at different states of finish;
- simultaneously transporting said engaged workpieces with said transport mechanisms in a linear direction to succeeding workstations along said work surface while at the same time rotating one or more of said engaged workpieces in the X-Y plane of said worksurface;
- simultaneously positioning said engaged workpieces at said succeeding workstations;
- simultaneously engaging said workpieces by said workstations;
- and
- simultaneously disengaging said workpieces from said transport mechanisms while said workpieces remain engaged by said workstations.
