Title:
YARN CUTTING CONTROLLING DEVICE, YARN MONITORING DEVICE, AND YARN WINDING DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/131511
Kind Code:
A1
Abstract:
A cut control unit (49) provided in a yarn monitoring device (15) controls, on the basis of a yarn defect detection signal S4, operation of a cutter (46) that cuts a yarn traversing a package while being wound on same. The cut control unit (49) comprises a yarn speed detection unit (48), a traverse position estimation unit (60), and a cut position adjustment unit (70). The yarn speed detection unit (48) detects the yarn speed V at which the yarn travels. The traverse position estimation unit (60) estimates the yarn traverse position on the basis of the yarn speed V detected by the yarn speed detection unit (48). The cut position adjustment unit (70) adjusts the cut position at which the cutter (46) cuts the yarn in accordance with the estimated yarn traverse position.
