Embodiment Construction

[0021] First, the contents of the embodiments of the present invention are listed and described.

[0022] (1) According to one aspect of the present invention, there is provided a method of manufacturing a twisted wire, which twists a plurality of wires extending along the twisted bow by rotation of the twisted bow to form a twisted wire, and rotates around the twisted bow installed on the twisted bow A winder within a range winds a stranded wire, the method comprising: a measuring step of measuring the tension of the stranded wire wound by the winder; a receiving step of receiving the measured value of the tension by radio outside the range of rotation of the twisted bow; based on The calculation step of calculating the set value of the axial torque of the winder by the measured value of the received tension; the receiving step of receiving the set value of the axial torque within the rotation range of the winch by radio; The set value of the axial torque is output to the out...

Abstract

Provided are a method and a stranding machine for manufacturing twisted wires to manufacture high-quality twisted wires. The stranding machine comprises wire collecting dies 3, which collect a plurality of wires 50a-50d; a twisting bow 5, which twists the collected lines to form twisted wires 50; a wire winder 10, which is placed within the rotation range of the twisting bow 5 and Winding of the twisted wire; a tension gauge (exemplified by the load unit 42) which measures the tension of the twisted wire wound by the winder; a master controller 30 which is placed outside the range of rotation of the twisted bow to receiving a measured value of tension, and calculating a set value of an axial torque of the winder based on the received measured value of tension; The setting value of the axial torque, and output the received setting value of the axial torque to the bobbin winder. The main controller calculates a set value of the axial torque of the spool based on the received measured value of the tension such that the tension of the strand wound by the spool is maintained at a constant value.

Description

[0001] Cross References to Related Applications [0002] This application is based on and claims the benefit of priority from Japanese Patent Application No. 2018-023219 filed on February 13, 2018, the entire contents of which are incorporated herein by reference. technical field [0003] The present invention relates to a method and twisting machine for manufacturing twisted wire from a plurality of wires. Background technique [0004] Traditionally, twisting machines have been proposed that twist a plurality of wires to make twisted wires. For example, Patent Document 1 discloses a stranding machine having a flyer and a cradle. The twisted bow is supported rotatably relative to a predetermined horizontal frame. The cradle is located within the swivel range of the winch bow and has a winder on which the strand can be wound. By controlling the rotational speed of the spool and / or the coupling force of the brake of the spool, the tension (also referred to as "winding tensi...
