Title:
ローラーシステムのメインローラーの直径を検出する直径検出方法
Document Type and Number:
Japanese Patent JP6717903
Kind Code:
B2
Abstract:
A method for obtaining a diameter is provided. The method is to be applied to a multi-roller module system and includes: designating a target linear velocity associated with a wire moving in the multi-roller module system, and a value of a presumed diameter parameter associated with a diameter of a main roller; calculating an initial rotational speed of the main roller; measuring a current rotational speed of the fixed-diameter rotating component; calculating an actual linear velocity of the wire; and determining that the value of the presumed diameter parameter equals an actual diameter of the main roller when it is determined that the ratio of the target linear velocity to the actual linear velocity is equal to one.
