【発明の詳細な説明】 （産業上の利用分野） 本発明は，複数の素線を撚合せて所定の導体抵抗を有す
る撚線を製造する方法の改良に関するものである。Description: TECHNICAL FIELD The present invention relates to an improvement in a method for producing a stranded wire having a predetermined conductor resistance by twisting a plurality of strands.

ある。(Prior Art) A twisting machine manufactures a twisted wire by sequentially twisting a plurality of wires wound from bobbin cages in which wire bobbins are stacked and arranged in series in a plurality of stages on a central wire. There is. Although the conductor resistance and outer diameter are important qualities of the stranded wire, it is almost impossible at present to economically measure the conductor resistance online.

の有効稼動率が低下する欠点があった。In the prior art, the conductor resistance is measured at a sample at the beginning of the operation or by stopping the line appropriately during the operation. However, the former method cannot guarantee the resistance of the entire length of the twisted wire, and the latter method requires a long measurement time to cool the conductor heated during the manufacturing process, resulting in a long measurement time and an effective operating rate of the machine. There was a drawback that it decreased.

態で運転することが行なわれているが，これは導体抵抗
のばらつきを起す欠点があった。For this reason, recently, manufacturing conditions are controlled to obtain a predetermined conductor resistance. That is, since the tension of the wire is related to the conductor resistance of the twisted wire, the input voltage of the torque motor that applies the tension to the wire is manually reduced stepwise according to the remaining dose of the wire bobbin to reduce the torque. It is made smaller so that the tension of the wire is almost constant. However, in this method, the operation is troublesome and the workability is low, and the input voltage of the torque motor, that is, the tension of the wire is adjusted stepwise, so that a uniform conductor resistance can be obtained over the entire length of the twisted wire. Can not. In addition, as the weight of the remaining wire decreases, the wire speed of the stranded wire is increased and the wire is always operated at maximum load, but this has the drawback of causing variations in conductor resistance.

とを特徴としている。(Structure of the Invention) The twisted wire method of the present invention detects the tension of the strand before twisting and the wire speed of the twisted wire, predicts the conductor resistance value of the twisted wire from the tension and the wire speed, and determines the predetermined value. It is characterized by twisting while controlling at least one of the tension and the linear velocity so that the conductor resistance value can be obtained.

機械の稼動率が向上する。By doing this, it is possible to obtain a stranded wire having a uniform conductor resistance at all times even when the wire speed changes greatly at the time of tapping and at the time of temporary stop, and it is always possible to obtain a stranded wire depending on the residual dose of the wire. Since the machine can be operated at the highest linear speed, the operating rate of the machine is improved.

とができる。In the method of the present invention, the tension T of the strand before being twisted, for example, the strand 14A is provided on the strand bobbin 10A, the input voltage U of the torque motor 20 for setting the tension T is detected, and the strand 16 is The linear velocity V is detected by the linear velocity meter 22, and the conductor resistance R of the twisted wire 16 is determined from the measured values of the input voltage U and the linear velocity V for setting the tension.
Is predicted by the microprocessor 24. Data such as the initial wire bobbin winding diameter Do and the wire diameter d are input to the microprocessor 24 in addition to the measured values U and V of the tension and the wire speed, and the remaining wire at the bobbin winding diameter D at any time is input. The length l can be calculated by the microprocessor 24 as follows.

よい。R = aT + bV + c (3) In the formula (3), a, b, and c are constants, for example, a = 1.97 × 10
-4 (Ω / kg), b = 3.91 × 10 -5 (Ω / (m / min)), c = 0.082
It can be 57 (Ω). Thus, the conductor resistance value R can be predicted by giving U and V. Therefore, for example, V, which is the detected value from the linear velocity meter 22, is measured to obtain T to obtain a predetermined conductor resistance value R by the formula (3), and the corresponding input voltage U of the torque motor 20 is generated. A predetermined conductor resistance value R can be obtained by outputting a control output from the microprocessor 24 as described above. As a result, in the past, the conductor resistance value fluctuated between 98% and 100% with respect to the 100% target, but when controlled by the method of the present invention, it could be kept within the range of 99% to 100%. It was confirmed. In the above embodiment, the tension T of the wire is controlled to obtain the predetermined conductor resistance value R.
The linear velocity V may be controlled so as to obtain a predetermined conductor resistance value R, or both the tension T of the wire and the linear velocity V may be controlled.

Since at least one of the wire tension and the wire speed is controlled so as to obtain a predetermined conductor resistance value, a uniform conductor resistance is always maintained even if the wire speed may change greatly at the time of the start and the temporary stop. The stranded wire can be obtained, and the machine can always be operated at the highest wire speed according to the residual dose of the wire.
