Yarn quality measuring instrument and yarn winding machine |
摘要 |
An object of the present invention is to provide a yarn quality measuring instrument and a yarn winding machine which can accurately evaluate the length of a yarn defect and detect periodic unevenness. A winder unit 10 constituting an automatic winder includes a clearer (yarn quality measuring instrument) 15. The clearer 15 detects thickness unevenness in a spun yarn 20 traveling with a speed thereof varied, to detect the thickness unevenness in the yarn. The clearer 15 includes a first yarn unevenness sensor 43 detecting the thickness of the traveling yarn, and a CPU 47. The CPU 47 receives a yarn speed signal obtained from an external rotation sensor 42 to sample signals from the first yarn unevenness sensor 43 at a sampling frequency according to the yarn speed signal (Fig.2). |
