To provide a yarn winding machine and a yarn winding method capable of quickly reducing the increased storage amount in a yarn storage device before a start of winding of a package in a winding device.SOLUTION: A spinning machine 1 is provided with: an air spinning device 4 for generating a yarn Y with airflow; a winding device 20 for winding the yarn Y generated by the air spinning device 4 to form a package P; a yarn storage device 6 arranged between the air spinning device 4 and the winding device 20 to temporarily store the yarn Y sent out from the air spinning device 4 and send the yarn Y to the winding device 20; a motor 28 for driving a drum 23 for rotating the package P in the winding device 20; and a control unit 90 which controls the motor 28 to execute, after a start of winding of the package P, a storage amount reduction control C for accelerating the rotation speed of the motor 28 until reaching a first specified speed V2 which is equal to or higher than a storage amount decrease speed V1 capable of reducing the storage amount of the yarn storage device 6.SELECTED DRAWING: Figure 4 【課題】巻取装置におけるパッケージの巻き取りの開始前に増大した糸貯留装置における貯留量を迅速に減少させることができる、糸巻取機及び糸巻取方法を提供する。【解決手段】紡績機１は、空気流によって糸Ｙを生成する空気紡績装置４と、空気紡績装置４によって生成された糸Ｙを巻き取ってパッケージＰを形成する巻取装置２０と、空気紡績装置４と巻取装置２０の間に配置され、空気紡績装置４から送出される糸Ｙを一時的に貯留して巻取装置２０に送出する糸貯留装置６と、巻取装置２０においてパッケージＰを回転させるドラム２３を駆動するモータ２８と、モータ２８を制御して、パッケージＰの巻き取りの開始後、糸貯留装置６の貯留量を減少させることが可能な貯留量減少速度Ｖ１以上の第一規定速度Ｖ２になるまでモータ２８の回転速度を加速させる貯留量減少制御Ｃを実行する制御部９０と、を備える。【選択図】図４
