Title:
COMBINED WEIGHING EQUIPMENT
Document Type and Number:
Japanese Patent JPH05149778
Kind Code:
A
Abstract:
PURPOSE:To suppress the quantity variation of articles on a distributing feeder caused by the fluctuation of the carrying-in quantity of the article carrying-in device of combined weighing equipment in which articles from the article carrying-in device are fed to a plurality of weighing sections by means of the distributing feeder. CONSTITUTION:When the quantity of articles on a distributing feeder 2 becomes less than a prescribed value and a photoreceptor 16 holds on a light receiving state for a prescribed period of time, articles are fed from an article carrying-in conveyor 1 until the photoreceptor 16 holds on a light shielded state for a prescribed period of time. A carrying-in time integration circuit 22 integrates the driving time of the conveyor l during a period in which the article carrying-in operations are performed a prescribed number of times and stopping time integration circuit 23 integrates the stopping time of the conveyor 1. When the article carrying operations are performed the prescribed number of times, the ratio of the carrying-in time to stopping time is calculated and the running speed of the conveyor 1 is changed so as to bring the ratio closer to 1:1.
