Apparatus for sensing objects on a moving conveyor

Image Number 6 for United States Patent #4979670.

A sensor for sensing and counting objects on a moving conveyor. Objects are moved on the conveyor past a sensor having first and second legs pivotally mounted about a fixed axis above the conveyor. The second leg is offset from the first leg in the direction of conveyor movement. As an object encounters the first leg, it causes the first leg to rotate toward the second leg. A proximity detector includes a target mounted on the first leg and a sensing element mounted on the second leg. The proximity detector detects movement of the first leg relative to the second leg and generates a pulse, thereby counting the object, when the first leg assumes a predetermined position relative to the second leg.
