Abstract
A conveyor scale assembly for use in combination with a conveyor belt for weighing an article on the moving conveyor belt. The conveyor scale assembly is comprised of a slider bed which contacts the underside of the moving conveyor belt which generates a friction force between the conveyor belt and the slider bed. Attached to the slider bed is a sensor which continuously measures the friction force and transmits data representing the measured friction force. A CPU receives and processes the representative data and provides a weight for the article on the conveyor belt.
Claims10
A device for weighing an article on a moving conveyor belt comprising:
- sensor means which contacts the underside of the moving conveyor belt and measures the friction force between the sensor means and the conveyor belt;
- and
- logic means coupled to said sensor means for determining the weight of the article based upon said measured friction force.
A method for weighing an article on a moving conveyor belt comprising:
- contacting the underside of the moving conveyor to generate a friction force;
- measuring the friction force;
- and
- determining the weight of the article based upon said measured friction force.
