A yarn winding device (100) includes a package driving unit (72) that rotates a bobbin (B); a rotational-speed detecting unit (73) that detects a rotational speed of the bobbin (B); a traverse guide (61) that traverses a yarn to be wound around the bobbin (B); a traverse-guide driving unit (62) that drives the traverse guide (61); a traverse control unit (81) that controls driving of the traverse guide (61); and a target-position-command determining unit that determines a pre-correction target-position command (Pt) for the traverse-guide driving unit (62) from the rotational speed of the bobbin (B). The traverse control unit (81) calculates a post-correction target-position command (Ps) from a target-position correction amount (Cp), which is a feed-forward component depending on a detection delay time of the rotational-speed detecting unit (73) and a response delay time of the traverse-guide driving unit (62), and the pre-correction target-position command (Pt), and controls the driving of the traverse-guide driving unit (62) according to the post-correction target-position command (Ps). |
