YARN WINDING DEVICE AND ALARM THRESHOLD VALUE DETERMINATION METHOD FOR DETECTION OF ROTATIONAL FAULTS IN A PACKAGE

Title:

YARN WINDING DEVICE AND ALARM THRESHOLD VALUE DETERMINATION METHOD FOR DETECTION OF ROTATIONAL FAULTS IN A PACKAGE

Document Type and Number:

WIPO Patent Application WO/2010/134294

Kind Code:

A1

Abstract:

Disclosed is a yarn winding device which can automatically detect, with high precision, rotational faults in a package. An automatic winder is provided with a winding unit (16) and a machine control device (11). The winding unit (16) performs the task of winding the yarn. The machine control device (11) controls the winding unit (16). The machine control device (11) includes a logical package calculation section (27) and a computation unit (17). The logical package calculation section (27) calculates the number of times the logical package is rotated. The computation unit (17) determines an alarm threshold value for deciding whether or not a package rotational fault exists, based on the number of rotations of the logical package. The alarm threshold value is input to the winding unit (16). An alarm decision unit (76) of the winding unit (16) makes an alarm decision by comparing the actual number of rotations of the package with the alarm threshold value.
