Hereinafter, a method of replacing the branch tubes 3 and 5 using the branch tube replacement apparatus 10 will be described with reference to Figs. 3 to 5 again. Referring to FIG. 3, the fabric 1 continuously produced and discharged from the fabric production device (not shown) is accumulated and wound up to an optimum capacity in the branch pipe 3 rotating at a high speed in the counterclockwise direction located at the fabric storage position. At this time, the far-end guide unit 30 is located at the first position. The contact roller 20 biased in the direction toward the paper tube 3 is retreated as the thickness of the fabric 3 accumulated in the paper tube 3 becomes thick. When the paper is retreated beyond a predetermined distance, 3 and the rotary plate 12 of the branch pipe supporting unit 11 is rotated counterclockwise by 180 °.

Referring to Fig. 4, the branch tube 3, in which the rotating end 12 is pivoted to the original end accumulation position and the fabric 1 is wound up and accumulated, is moved to the branch pipe mounting position, and the new branch pipe 5 at the branch pipe mounting position Move to the tail storage position. Also, the first far-end supporting roller 17 on the upper side is moved down and the second far-end supporting roller 18 on the lower side is moved upward. The raw fabric 1 is pulled as the branch pipe 3 moving to the branch pipe mounting position continues to rotate and is guided by the first original end supporting roller 17 so that the distance between the contact roller 20 and the new branch pipe 5 And the first far-end supporting roller 17 to the branch pipe 3 at the branch pipe mounting position.

Referring to Fig. 5, the counterclockwise rotation of the frame 31 moves the far-end guide unit 30 to the second position. The fabric 1 is pressed by the first fabric guide rollers 55 and guided by the first to third fabric guide rollers 55, 57 and 59 so that the fabric 1 is guided by the contact rollers 20 Via the first to third far-end guide rollers 55, 57 and 59 and the first far-end supporting rollers 17 between the new branch pipe 5 and the new branch pipe 5, to the branch pipe 3 at the branch pipe mounting position. The first and second nip rollers 35 and 45 bring the fabric 1 into close contact with the outer peripheral surface of the new branch pipe 5 when the cloth guide unit 30 is in the second position. The new branch tube 5 also begins to rotate at a high speed in the counterclockwise direction and the cutting blade 61 (see Fig. 1) cuts and separates the fabric 2 and at the same time the air blowing nozzle 71 Pressure air is injected into the second branch pipe 2a to guide the distal end 2a of the raw fabric along the outer peripheral surface of the new branch pipe 5. [

As the new branch tube 5 continues to rotate, the fabric 2 newly introduced onto the distal end 2a of the fabric is accumulated, and as a result, the stable winding of the fabric 2 continues. At this time, the far-end guide unit 30 returns to the first position again. On the other hand, the previously advanced fabric 1 is wound and accumulated in the paper tube 3 at the paper tube mounting position after being separated. After stopping the rotation of the branch tube 3, the first branch tube supporting shaft 13 is separated from the first branch tube supporting shaft 13, and a new branch tube whose fabric is not wound is mounted again on the first branch tube supporting shaft 13. When the fabric 2 is wound and accumulated in the branch pipe 5 fitted to the second branch pipe supporting shaft 15 by an appropriate amount, the above-described branch pipe replacement process is repeated. Thus, the core tube replacement and the winding and accumulation of the fabric are continuously performed without delay or stoppage of the operation.
