Abstract
PURPOSE: To improve arithmetic accuracy for a reeled roll diameter, by measuring, calculating actual thickness of reeled materials and performing arithmetic operation of the reeled roll diameter.
CONSTITUTION: There are provided a reeled-back roll one-turn detector 22 in the side of a reeled back roll 21 of a reel device and a length measurement pulse generator 29 in the side of a reeled roll 30, and a reeled roll diameter arithmetic unit is constituted by a circumference measuring counter 35, material thickness calculator 38, length measuring counter 40, length comparator 42, reeled roll sectional area calculator 43, area comparator 45 and reeled roll diameter counter 47. Pulses from the roll one-turn detector 22 and the pulse generator 29 are counted by the circumference measuring counter 35 and the length measuring counter 40 and output as a roll circumference value C and output l0, then material thickness (t) is counted through arithmetic operation by the material thickness calculator 38. Then sectional area So of the reeled roll is counted through arithmetic operation by the reeled roll sectional area calculator 43, and a reeled roll minimum addition unit (d) is added to the reeled roll diameter counter 47 to perform arithmetic operation of a reeled roll diameter.
