Abstract (en)
A yarn winding device configured to wind yarn onto a cone-shaped winding bobbin to form a cone-shaped package, the yarn winding device includes:a cradle configured to rotatably support the winding bobbin;a drive motor attached to the cradle and configured to rotate the winding bobbin;a traverse device configured to traverse the yarn;a package-peripheral-speed acquisition section configured to acquire, as a first peripheral speed, a peripheral speed of the winding bobbin;a touch roller configured to be rotated by rotation of the winding bobbin;a roller-peripheral-speed calculation section configured to calculate, as a second peripheral speed, a peripheral speed of the touch roller; anda contact-state determination section configured to compare the first peripheral speed acquired by the package-peripheral-speed acquisition section and the second peripheral speed calculated by the roller-peripheral-speed calculation section, thereby determining a contact state of the bobbin that is in contact with the touch roller.
