Then, the drive device 37 is activated, the movable arm 39 is rotated counterclockwise, and the receiver 40 is moved to the full tube 53 position of the cradle 9. When the receiver 40 moves to the doffing position of the cradle 9, a cylinder (not shown) is actuated to move the cradle operating arm 36 in the longitudinal direction of the tube, and the cradle 9 is pushed out and released from the grip by the tube chuck 10. be done. Then,
The fully wound tube 53 falls onto the receiver 40 and is held there. When the fully wound tube 53 is received by this operation, the movable arm 39 is rotated counterclockwise and returned to the standby position. ) A full tube 53 is dropped on top and reloaded. When the movable arm 39 returns to the standby position, the same operation as the above-mentioned thin thread tube feeding operation is performed to feed the thin thread wound tube 51 to the tube chuck 10 of the cradle 9. After the feeding operation of the thin thread winding tube 51 is completed, the yarn splicing device (not shown) is moved to the yarn splicing operation position, and the yarn spun from the spinning device 5 and the yarn pulled out from the thin thread winding tube 51 are separated. The yarn is spliced and the yarn is wound.
