To provide a yarn winding device can continuously wind yarn up to a winding end from a winding start.

A winding unit 10 includes an accumulator 61 can store the yarn 20 before being wound on a package 30 and can draw out this stored yarn 20 to the yarn supplying bobbin 21 side, and a unit control section 50. The unit control section 50 draws out a portion having a yarn defect from the accumulator 61 to the yarn supplying bobbin 21 side when a clearer 15 detects the yarn defect, and catches and guides this drawn-out yarn 20 to a splicer device 14 by an upper yarn guide pipe 26, and controls so as to perform ending work by guiding lower yarn caught by a lower yarn guide pipe 25 to the splicer device 14.
