The set value of the target frequency for the second frequency converter 51 is transmitted via the signal line 52 in accordance with an input operation on the input unit 32 of the control box 3. As described above, the setting of the winding speed for the double twisting machine 1 and the twining machine 2 can be performed on the common input unit 32 using the common display unit 31.

7 can be driven at independent rotation speeds.
Each of the rotation speed control devices 53 is connected to a switch 57 provided for each of the weights. When the operator operates the switch 57 of the specific weight, the motors 16 and 17 of the weights are simultaneously stopped or stopped. It can be driven.
The AC power supplied from the commercial power supply 46 is converted into DC by an AC / DC converter 54 in the control box 3 and then a power line (DC bus) 55 laid in the machine longitudinal direction.
The rotation speed is supplied to the motor 17 via the rotation speed control device 53. Each rotation speed control device 53 can individually drive each motor 17 at a predetermined rotation speed based on a preset target frequency (target speed).

As described above, by performing the feedback control for each motor 17, it is possible to accurately maintain each motor at a desired number of revolutions, and even when the set value of the number of twists differs for each weight, It is possible to obtain a twisted yarn having an accurate twist number. The number of twists of the yarn Y to be twisted is determined by the relationship between the rotation speed of the spindle and the winding speed,
Since fluctuations in the spindle speed directly affect fluctuations in the number of twists, it is very important to maintain the spindle speed accurately at the set value in order to obtain high-quality twisted yarn.

The power lines 44, 49, 55 and the signal line 56 are arranged in ducts (not shown) arranged at appropriate locations along the machine longitudinal direction. Further, boards (not shown) constituting each rotation speed control device 53 are also arranged in the same duct.

Further, in the present embodiment, a winding device including a double twisting machine 1 provided continuously with a twisting unit for four spindles and a plying machine 2 provided continuously with two spindles will be described. However, it goes without saying that the number of weights of the double twisting machine 1 and the twining machine 2 is not particularly limited. By setting the number of weights of the double twisting machine 1 and the number of weights of the twining machine 2 in consideration of the production speed, the production capacity with the other is balanced, and it becomes possible to operate all the weights efficiently. . Further, for example, the weight of the double twisting machine 1 and the weight of the twining machine 2 may be alternately arranged, and the arrangement of the weights of the double twisting machine 1 and the double yarn machine 2 is not limited to the above example. Absent.

Also, an example has been described in which the twining machine 2 as a pre-process and the double twisting machine 1 used as a subsequent process are arranged side by side.
