Abstract (en)
[origin: EP2433889A1] A yarn winding device capable of automatically detecting an abnormal package rotation with a high accuracy is provided. An automatic winder includes a winding unit (16) and a machine control device (11). The winding unit (16) performs a yarn winding operation. The machine control device (11) controls the winding unit (16). The machine control device (11) includes a theoretical package calculation section (27) and a computation section (17). The theoretical package calculation section (27) calculates the theoretical number of package rotations. The computation section (17) determines an alarm threshold value for determining an abnormal package rotation, based on the theoretical number of package rotations. The alarm threshold value is inputted to the winding unit (16). An alarm determination section (76) included in the winding unit (16) compares the actual number of package rotations with the alarm threshold value, and performs an alarm determination.
