ABSTRACT:
A control apparatus for a filling machine of the type employing a hopper and rotary feed auger determines the exact number of auger revolutions required to deliver a preselected weight of material to be dispensed by weighing the volume of material delivered by a given number of auger revolutions and computing the ratio of the number of auger revolutions to the weight of the volume delivered. The ratio is then divided into the desired weight to determine the actual number of auger revolutions required to deliver the desired weight. The control apparatus also measures the amount of rotation of the rotary auger after the auger is braked at the end of each fill cycle and increments or decrements a preselected set point number of auger revolutions, depending upon whether the actual number of auger revolutions is greater than or less than the set point, to compensate for auger rotation after braking.
