At the same time as the full tube support shaft 31 moves up as shown in FIG. 2, the empty paper tube support frame 47 supporting the two empty paper tubes B slides to a position facing the bobbin holder BH,
The pusher 48 inserts two empty paper tubes B. The empty paper tube support frame 47 is cut out from the paper tube box 41 by a cutting device 42.
After that, two more paper tubes B are supplied, and the paper tube B is again slid to a position facing the bobbin holder BH. This paper tube inserting operation is performed while the full tube P is transferred onto the creel transport vehicle 23. Therefore, the cycle time of the doffing device 22 is determined by the time until the full pipe P is received and transferred to the creel transport vehicle 23, and can be considerably shortened as compared with the case where the full pipe P is transported. Also doffing device 22
The empty paper tube B itself is stored, and cutting and insertion are performed by a simple lateral movement. Therefore, a paper tube supply device is separately provided in the take-up winder 1.
Since it is not necessary to provide it along with, it is possible to shorten the cycle time for inserting the empty paper tube.

Incidentally, the reason why the four full tubes or empty paper tubes of the bobbin holder BH are received or inserted in two portions in two steps is to narrow the machine width of the doffing device 22. If the doffing device 22 has enough space to widen the machine width, a doffing device that can receive or insert four full pipes or empty paper pipes at one time can be used.
