摘要： 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.

摘要： An apparatus for automatically adjusting a preselected volume of material dispensed by a volumetric filling machine into containers to be filled by weight. The apparatus has a scale for sequentially weighing a plurality of containers each containing the preselected volume of material dispensed by the filling machine and sequentially generating an equal plurality of weight signals representative of the weight of the dispensed material in the containers. A microprocessor receives and stores the sequential weight signals and stores them in a memory, and calculates an average weight value. The microprocessor then compares the average weight value to a preselected weight value and generates a correction signal representative of the comparison. A controller responsive to the correction signal adjusts the preselected volume by an amount sufficient to cause the average weight value to be equal to the preselected weight value.
