As shown in the figure, each unit 2 of the double twister 1 is provided with a spindle 10 for vertically supporting the yarn feeding package 4 below, and a cradle arm 12 for horizontally supporting a paper tube 11 above. The yarn Y drawn from the yarn feeding package 4 is passed through the center hole thereof, double-twisted and guided upward, and wound around the paper tube 11 which is rotationally driven by the rotating drum 13 to form the winding package 8. ing.

A display lamp 15 is provided above the yarn supplying package 4 and is turned on when the drop wire 14 falls due to yarn breakage or the like.

At the rear of the rotary drum 13, a conveyor 16 for carrying out the doffed winding package 8 is provided, and at the front of the spindle 10, there is provided a conveyor 18 for inserting the yarn feeding package 4 in a tray 17 and carrying it. It is provided along each.

In this embodiment, as the yarn supplying package 4, two-stage type yarn supplying packages 4a and 4b in which uncombined packages are vertically stacked are used, and the yarns from the upper and lower packages 4a and 4b in the unit 2 are combined. It is designed to be double twisted while being threaded.

A robot 3 is rotatably provided on the front portion of the unit 2 constructed as described above along the arrangement direction. The robot 3 is composed of a robot main body provided with wheels 20 which run on rails 19 which are horizontally arranged above and below the unit 2, and detects a lit indicator lamp 15 by a sensor 21 to stop it in front of the unit 2. The presence or absence of residual yarn in the yarn supplying package 4 of the weight is confirmed by the residual yarn sensor 23 provided at the tip of the rotatable operation arm 22.

When the robot 3 determines that there is residual yarn, the operating arm 22 operates the peg 24 for the yarn supplying package 4.
The yarn is pulled out by a yarn feeding mechanism (not shown), and the yarn end is sucked and held by the suction pipe (not shown) of the arm after threading, and the yarn end is tilted and the yarn guide piece The advancing / retreating operation hooks the yarn on the snell wire 25 and the yarn guide roller 26 and guides it onto the yarn joining device 27.

On the other hand, the drive roller 28 comes into contact with the winding package 8 which has been pulled up from the rotary drum 13 and stopped, and the suction arm 29 approaches, so that the winding package 8 is rotated in the yarn unwinding direction and the surface of the yarn layer is rotated. By sucking, the yarn end is pulled out and guided onto the yarn joining device 27. The yarns thus guided are automatically spliced by the splicing device 27. When the yarn splicing is completed, the winding package 8 is rotated in the winding direction by the drive roller 28, and the drive roller 28
