As shown in FIG. 12, the movement allowing member 56 protrudes from the central portion of the flange portion 52B, and the release button 32 can be pressed by the pressing portion 56A.

[0058] The pressing portion 56A and the outer edge holding portion 55 are arranged at a holding position HI where the outer edge holding portion 55 of the holding arm 54 is arranged below the flange 10A of the bobbin 10 in the axial direction of the rotating shaft 23. The relative position of the pressing portion 56A is positioned so that the pressing portion 56A is disposed at the pressing position H2 where the release button 32 is pressed downward.

Next, a method for attaching / detaching the bobbin 10 using the bobbin removing device 50 having the above-described configuration will be described.

[0060] The procedure for mounting the bobbin 10 is performed in the same manner as in the first embodiment. When removing the bobbin 10, the bobbin removing device 50 is lowered in the X direction, the outer edge holding part 55 of the holding arm 54 is arranged at the holding position HI, and the pressing part 56A is arranged at the pushing position H2. Stop descent at the position (see Fig. 12). At this position, the tip of the pressing portion 56A pushes the release button 32 in the X direction. As a result, the holding piece 35 is disposed at the inner position P2, and the bobbin 10 can move in the Y direction.

[0061] With the position of the pressing portion 56A maintained, as shown in FIG. 13, the outer edge holding portion 55 is moved inward in the direction of arrow D, and the flange 10A of the bobbin 10 is clamped. At this time, since the holding portion 55B has an inclination S, the bobbin 10 slides along the inclination S in the arrow Y direction. Next, the main body 52 is moved in the arrow Y direction. Then, as shown in FIG. 14, the release button 32 is a force that moves in the direction of the arrow Y. The bobbin 10 is moved in the direction of the arrow Y, and the inner wall of the bobbin 10 is in contact with the holding piece 35. The holding piece 35 remains in the inner position P2. Therefore, the main body 52 can be further moved in the arrow Y direction, and the bobbin 10 can be extracted from the bobbin fixing device 20.

[0062] According to the present embodiment, the holding portion 55B is pressed while the release button 32 is pressed by the pressing portion 56A. The bobbin 10 is moved to a position where the holding piece 35 can be disposed at the inner position P2 by the inclination S configured as described above, so that the bobbin 10 can be easily removed from the bobbin fixing device 20 without the operator having to operate the release button 32. Can be extracted.
