Abstract

By securing two ball bushings orthogonally to each other and providing the joined pair at each of four corners on suitably arranged orthogonal shafts, a plate can be fastened to the bushing pairs and easily moved to the desired coordinate position. By making one dimension of the plate large with respect to the other, the bushings and shafts can accommodate limited skewing. This permits the suspension of position sensitive equipment on the plate for operation on variably positioned elements below the plate.

Floating Positioner

By securing two ball bushings orthogonally to each other and providing the joined pair at each of four corners on suitably arranged orthogonal shafts, a plate can be fastened to the bushing pairs and easily moved to the desired coordinate position. By making one dimension of the plate large with respect to the other, the bushings and shafts can accommodate limited skewing. This permits the suspension of position sensitive equipment on the plate for operation on variably positioned elements below the plate.

Referring to the figure, commercial ball bushings 1 are joined to form an orthogonally oriented pair at each of four corners of plate 2. The bushings are mounted with respective orthogonally arranged shafts 3. Below the plate is mounted positioning or testing devices 4 which can operate on items moving along a conveyor (not shown). The variation in position of the items on the conveyor at each stop can be accommodated by the floating plate without relocating the conveyed items.
