Abstract

A cutting control unit (49) included in the yarn monitoring device (15) controls the operation of a cutter (46) that cuts the yarn wound in a package while traversing based on the yarn defect detection signal S4. The cutting control unit (49) includes a yarn speed detecting unit (48), a traverse position estimating unit (60), and a cutting position adjusting unit (70). The yarn speed detector (48) detects the yarn speed V at which the yarn runs. The traversing position estimating unit (60) estimates the traversing position of the yarn based on the yarn speed V detected by the yarn speed detecting unit (48). The cutting position adjustment unit (70) adjusts the cutting position where the cutter (46) cuts the yarn based on the estimated traverse position of the yarn.

Description

technical field [0001] The present invention mainly relates to a yarn cutting control device capable of adjusting a cutting position of a yarn cut by a cutting device. Background technique [0002] Conventionally, in a yarn winding device that winds a yarn into a package while traversing the yarn, there is known a structure in which when the yarn is cut due to detection of a yarn defect, etc., the yarn is removed. A structure in which the yarn is cut at a time other than the time when the thread is in the vicinity of the turning back position of the traverse. Patent Document 1 discloses an automatic winder as such a yarn winding device. [0003] The automatic winder of this Patent Document 1 is an automatic winder that rewinds the yarn to the package while traversing, and cuts the yarn by detecting a defect in the yarn. A unit and a control unit for controlling the cutting timing of the yarn according to the yarn defect detection based on the detection signal of the detect...
