ABSTRACT:
An automatic capacitor winding machine including a photoelectric device for sensing the position of a capacitor tab which is rotated by a rotating arbor is disclosed. The sensing device is characterized by a light source providing a light-beam directed along a line which lies in a plane perpendicular to the axis of rotation of the arbor. The tab crosses the line along which the light-beam is directed only twice. The width of the light-beam is greater than the width of the tab at the line crossing nearest the light source. A photoelectric detector is positioned to receive light directed along the line and it is responsive to light impinging thereon. The detector has an angle of light acceptance such that the light-beam is prevented from impinging on the detector only when the tab is at the line crossing which is nearest to the light detector.
This abstract is not to be taken either as a complete exposition or as a limitation of the present invention. However, the full nature and extent of the invention is discernible only by reference to and from the entire disclosure.
