PROBLEM TO BE SOLVED: To reduce failure of direction conversion in a yarn feeding bobbin direction conversion device and abnormal stop or the like of the yarn feeding bobbin direction conversion device.SOLUTION: A bobbin direction alignment device 6 convers a direction of a yarn feeding bobbin 3 in which a yarn is wound on a core tube having a large diameter part and a small diameter part having a diameter smaller than that of the large diameter part, and supplies the yarn feeding bobbin 3 to a downstream side of a supply path 69. The bobbin direction alignment device 6 comprises a pair of core tube guide parts 63, and a bobbin detection sensor, and a path changing operation part. The pair of core tube guide parts 63 are located in order to guide the large diameter part and the small diameter part of the yarn feeding bobbin 3. The bobbin detection sensor detects a state of the yarn feeding bobbin 3 located on the core tube guide part 63. The path changing operation part changes the supply path 69 of the yarn feeding bobbin 3 according to the detection result of the bobbin detection sensor.SELECTED DRAWING: Figure 8 【課題】給糸ボビン方向変換装置において、方向変換の失敗及び給糸ボビン方向変換装置の異常停止等の頻度を低減する。【解決手段】ボビン方向揃え装置６は、大径端部と、当該大径端部よりも直径の小さい小径端部と、を有する芯管に糸が巻かれた給糸ボビン３の方向を変換して、当該給糸ボビン３を供給パス６９の下流側に供給する。このボビン方向揃え装置６は、１対の芯管案内部６３と、ボビン検出センサと、パス変更動作部と、を備える。１対の芯管案内部６３は、給糸ボビン３の大径端部及び小径端部を案内するために配置される。ボビン検出センサは、芯管案内部６３に配置された給糸ボビン３の状態を検知する。パス変更動作部は、ボビン検出センサの検出結果に応じて、給糸ボビン３の供給パス６９を変更する動作を行う。【選択図】図８
