Is a doffing device that can run freely along the automatic winder by the rail 5. The doffing device 6 performs a series of the following operations. When the specific winding unit 2 finishes winding the package P, the rewinding is interrupted and the lamp 11 is turned on. The doffing device 6 detects the lighting of the lamp 11 and stops in front of the weight. Then, the yarn Y is picked up. Next,
The cutter cuts the yarn Y and holds the lower yarn.
Next, the cradle arm 10 is opened and the package P is discharged onto the discharge conveyor 4. Next, the paper tube 13 is gripped from the box 3 and carried to the cradle arm 10. Next, the yarn Y is sandwiched between the paper tube and the cradle arm 10, and the sandwiched yarn Y is moved to the bunch winding position to perform the bunch winding. Then, the button 12 is pressed to start the winding unit 2.

Equipment provided in the doffing device 6 that performs the above-described series of operations will be described with reference to FIG. Reference numeral 15 is a pickup for picking up a thread, 16 is a cutter for cutting and gripping the thread, 17 is an opener for opening and closing the cradle arm, 18 is a chucker for gripping the paper tube and carrying it to the cradle arm, and 19 is a predetermined position of the thread. A thread shifting lever, 20 is a roller for rotating a package or a paper core when picking up a thread and winding a bunch,
