The suction port 17a at the lower end is swung by the expansion and contraction operation.

Below the suction pipe 17, a cutter 23 such as scissors is provided. The cutter 23 advances and retracts due to the expansion and contraction of the actuator 24, and cuts the yarn running between the suction pipe 17 and the package 1 which are in the lowered position when the cutter 23 advances. The automatic surface treating machine 300 having the above-mentioned configuration carries out the surface treatment of exfoliating the package surface layer and fixing the yarn end by the steps shown in FIGS. 5 (A) to 5 (F).

First, as shown in FIG. 5 (A), the rotating ring 13
Is set so that the guide 14 is located on the right side, and the fully wound package 1 is mounted on the bobbin support shaft 12. Then, the bobbin supporting shaft 12 is rotated to rotate the package 1
While rotating in the direction opposite to the winding direction of the yarn as indicated by the arrow, compressed air is blown from the jet nozzle 16 onto the surface layer of the package 1 to erect the yarn end Ye. The jetting by the jetting nozzle 16 is not always necessary, but if this jetting operation is performed, the suction of the yarn end Ye by the suction pipe 17 performed in the next step can be simplified.

Next, as shown in FIG. 5B, the suction tube 17 is lowered to near the surface layer of the package 1, and the yarn end Ye is sucked from the suction port 17a, whereby the bunch winding portion B is peeled off. At this time, the sensor detects the time when the yarn end Ye starts to be sucked, and the package 1 (bobbin support shaft 12) after that is detected.
By counting the number of rotations, the exfoliation length of the yarn including the bunch winding portion can be measured. Further, as a result, the winding amount of the package 1 can be easily managed.

When the exfoliation of the bunch winding portion B is completed, the rotation of the package 1 is once stopped, and the suction tube 17 is raised to the original position while continuing the suction. Next, as shown in FIG. 5 (C), the rotating ring 13 is rotated in the direction of the arrow so that the package 1
The yarn Y stretched between the suction pipe 17 and the suction pipe 17
And the package 1 is rotated again in the direction opposite to the yarn winding direction. Due to this relative rotation, the guide 14 moves as shown in FIGS. 5 (D) and (E), and stops when the guide 14 comes to a position below the suction pipe 17 again as shown in FIG. 5 (F). At the same time, the package 1 is stopped. As the guide 14 makes one turn around the package 1 in this manner, the guide 14 scoops up the yarn Y wound on the surface layer of the package 1 by one turn.

Next, the suction pipe 17 which continues suction is lowered, and the head is shaken to guide the suction port 17a to the guide 14
To bring it closer to. Further, when the guide 14 is slid in the axial direction to retract from the upper side of the package 1 and the suction tube 17 is lowered, the suction tube 17 receives the yarn Y ₁ on the yarn end Ye side which has already been sucked, Guide 1
The yarn Y ₂ picked up by 4 is also sucked (see FIG. 7).

As described above, when the suction pipe 17 sucks the yarn Y ₁ on the yarn end Ye side and the yarn Y ₂ picked up in a loop shape, in addition to the linear suction up to that time, the suction port 17a
When a spiral jet flow is generated inside the yarn, the yarns Y ₁ and Y ₂ are twisted and / or entangled with each other to form one converged state.
When the single convergent yarn is cut by advancing the cutter 23, the convergent yarn remaining on the package 1 side is formed as the yarn end fixing portion Yk.

The package 1 for the product whose surface treatment has been completed as described above is moved to the peg 42 of the carriage 200 arranged at the end of the bobbin supporting shaft 12 by operating the pusher 55 as shown in FIG. Listed. The dolly 200 that has received the package 1 moves to a product storage location (not shown), unloads the package 1 there, and performs one of the surface treatment operations.
The cycle ends. Carriage 2 after the above 1 cycle
00 waits until the next winding of the package by the winding machine 100, and then repeats the above cycle each time the winding is completed.
