The lifting drive motor 40 of the inner yarn branch rail lifting section 131 drives the lifting main shaft 41 to rotate, the winding belt 43 on the winding wheel 42 is put down, the inner yarn branch rail lifting section 131 descends, the conveying vehicle group 25 and the inner yarn package 48 thereon descend along with the lifting drive motor, and the travel sensor 44 detects that the inner yarn branch rail lifting section 131 descends to the proper position and stops. The operator removes the inner yarn package 48 of the cradle type suspension 45 and places it into the spindle pot 18. Or the operator moves the inner yarn hanging device 21 over the spindle pot 18, presses the four-sided connecting rod 212 on the inner yarn hanging device 21, retracts the first hanging rod 214 and the second hanging rod 215, and releases the inner yarn package 48 to drop into the spindle pot 18, which is suitable for heavier weight yarns, such as industrial yarn packages.

After the yarn loading operation of the inner yarn package 48 is completed, the inner yarn feeder rail lifting section 131 is operated to lift and align with the inner yarn feeder rail 13. The empty transport vehicle group 25 is started and the operator completes the inner yarn splicing.

The operator drives the climbing carriage 17 to place the small-diameter inner yarn package on the yarn placing plate 14 on the tube seat on the fixed bracket, and to connect the small-diameter inner and outer yarn packages and the outer yarn on the movable bracket 11 end to end. Then corresponding spindle positions are started, and twisting operation is started.
