SWITCHING METHOD AND SWITCHING DEVICE OF CARRYING LINE IN CARRYING CONVEYOR OF BOBBIN

PROBLEM TO BE SOLVED: To switch carrying lines to/from each other by simple operation when a carrying line of respective bobbins in an aggregate conveyor is switched to the other optional carrying line. SOLUTION: Disk-shaped guide members 3 and 3' where a straight passage 4 to insert/guide a bobbin K into/to its center in the disk-shaped members 3 and 3' is formed in a proper position on plural-row carrying lines to connect a fine spinning frame and a finishing winder to each other and an inlet gate 5 is arranged in one end part of the straight passage 4 and an outlet gate 6 is arranged in the other end part so as to be openable-closable, are rotatably arranged so that an inlet and an outlet of its straight passage 4 can be selectively connected to either of the respective carrying lines, and the outlet gate 6 of the straight passage 4 is closed, and the inlet gate 5 is opened by being connected to a desired carrying line, and when the prescribed number of bobbins enter the straight passage 4, the inlet gate 5 is closed, and the guide members 3 and 3' are rotated, and the outlet gate 6 is opened by being connected to a carrying line to be switched, and the carrying lines of the bobbins are switched to/from each other.
