Under a state in which the male connector section 103 is not connected to the female connector section 107, the valve body closely makes contact with the connecting port 107a to block the connecting port 107a.

If the male connector section 103 is detached from the female connector section 107, the valve 107b is closed, and the compressed air from the compressed air pipes L65, L67, and L69 is shut such that the compressed air does not leak outside. Even if the cradle device 100 of a spinning unit 2 is detached from the frame 6, since the compressed air does not leak out from the compressed air pipes L65, L67, and L69, the operation of other spinning units 2 is not required to be stopped.

  • a plurality of cradle devices 100 of the spinning machine 1 can be individually detached from the frame 6 as a module. Even if at least one of the plurality of cradle devices 100 is detached, since flow of the compressed air from the compressed air pipes L65, L67, and L69 to the outside is shut by the valve 107b of the female connector section 107, a supplying state of the compressed air to other cradle devices 100 is hardly influenced. Thus, even when performing the maintenance operation on at least one of the cradle devices 100, the yarn winding operation can be continued in the other cradle devices 100.
  • the opening-and-closing shaft 71c adapted to open and close the cradle arm 71 of the cradle device 100 is provided below the supporting shaft 70 of the cradle arm 71.
  • the bobbin holder 105 and the opening-and-closing shaft 71c are located away from one another. Thus, even if the width of the package 45 is changed, change in an angle formed by the holding arm 71a and the holding arm 71b for sandwiching the package 45 is small.
  • the package 45 can be sandwiched and held under a state in which the holding arm 71a and the holding arm 71b are almost parallel. As a result, a shift in rotational axis of the bobbin holders 105 is small, and the held package 45 can be smoothly rotated.
  • the swing shaft of the cradle arm may extend across the plurality of spinning units 2, and may be commonly used for the plurality of spinning units 2.
  • arranging the opening-and-closing shaft of the holding arm at a position lower than the swing shaft of the cradle arm is difficult.
