Abstract

A basic vibrating orienter table T causes a part dropped to slide under vibration to a low point and to assume an orientation of substantially minimum potential energy, i.e., with its heaviest or most dense portions at lowest elevation E. Orientation of a part is sensed by projecting light across the orienter from cylindrical source lenses L towards sensor fiber-optical sensors S. Each sensor S is disposed directly across the surface of the orienter from its light source. The cylindrical lenses receive light from optical-fiber rods 1 which are sequentially illumination one at a time by rotary light source 2, Which shines through aperture 3. A rotary photocell 4 looks through aperture 5 at the optical-fiber rods 6 connected to sensor S.

Use of Shadow Frame with Vibrating Plate Orienters

A basic vibrating orienter table T causes a part dropped to slide under vibration to a low point and to assume an orientation of substantially minimum potential energy, i.e., with its heaviest or most dense portions at lowest elevation
E. Orientation of a part is sensed by projecting light across the orienter from cylindrical source lenses L towards sensor fiber-optical sensors S. Each sensor S is disposed directly across the surface of the orienter from its light source. The cylindrical lenses receive light from optical-fiber rods 1 which are sequentially illumination one at a time by rotary light source 2, Which shines through aperture
3. A rotary photocell 4 looks through aperture 5 at the optical-fiber rods 6 connected to sensor S. The photocell unit 7 and source 2 are rotatably carried in shaft 8 turned by pulley 9 and belt-10. Thus the entire table T is scanned in one revolution.
