AUTOMATIC ARITHMETIC OPERATION METHOD OF INITIAL WINDING DIAMETER IN WINDING DEVICE

摘要

PROBLEM TO BE SOLVED: To solve the problem of reaching uncontrollability by erroneous measurement and erroneous input, when artificially performing measurement and input, due to requiring to measure and input an initial winding diameter of a winder to a device when starting operation of a winding device, though a sending-out speed and a taking-over speed of the material are controlled to be the same and a dancer position of a material is controlled so as to come to the center, in the winding device.;SOLUTION: The material is placed in the dancer lowest position, and the sending-out speed is set to 0, and when performing winding control from an imaginary initial winding diameter from such a state, the material gradually moves to the center from the lowest position in a dancer position, and the winder stops. A line speed and a winder rotating speed during this time increase by starting from 0, and soon becomes 0 after reaching a certain maximum value. The initial winding diameter is arithmetically operated based on the respective maximum values at this time. Since the device automatically performs measurement and input by an operator, the problems of the erroneous measurement and the erroneous input to be solved can be solved.;COPYRIGHT: (C)2010,JPO&INPIT
