Control device for raw material cutting equipment, control method for raw material cutting equipment, and program

摘要

PROBLEM TO BE SOLVED: To automatically close a cutout regulation gate that is constantly opened at a set aperture during operation, at timing of decreasing as much as possible raw materials on a sieve of a material storage designated when terminating the automatic cutout of raw materials, in a case where raw materials in the material storage are cut out by a feeder via a cutout regulation gate provided at an opening of the material storage, and feeding them via the sieve to a weighing hopper.SOLUTION: A control device of raw material cutout equipment calculates a necessary cutout weight of raw materials, a weight of cutout raw materials until full closing, and a weight of raw materials left on the sieve, and calculates a value obtained by subtracting the weight of cutout raw materials until full closing, and the weight of raw materials left on the sieve from the necessary cutout weight of raw materials, as a cutout-regulation-gate closing command timing weight. After that, when the weight measured by a weight scale 280 reaches the cutout-regulation-gate closing command timing weight, a closing operation of the cutout regulation gate 220 is started.SELECTED DRAWING: Figure 4
