Weighing and filling method and apparatus

摘要

A method and apparatus for rapidly and accurately dispensing measured amounts of powdered material from a vibratory feeder with a shaker rod extending through an orifice at the discharge end of the feeder and which rod undergoes reciprocal movement in response to vibration of the feeder to regulate the advancement of the powdered material. Alternate forms of control algorithms are employed in association with a computer to determine the optimum rate of feed and drive level for a given powder and feeder arrangement to result in a specific final weight within an acceptable tolerance for each fill cycle.
