張力調整装置に関するものである。Detailed Description of the Invention A. Field of Industrial Application This invention prevents deterioration in wire performance when thin wires, such as thin copper wires, optical fiber core wires, etc., which have low tensile strength and are easy to stretch, are twisted together. The present invention relates to a tension adjustment device for unwinding wire from a bobbin with a constant tension, and particularly to a tension adjustment device suitable for installing the device in a rotating body such as a planetary type twisting machine.

き張られており、これによって線に張力が与えられる。In conventional optical fiber cable twisting machines, since the optical fiber cable is weak, the tension of the cable fed out from the bobbin must be precisely controlled. As a tension adjusting device for this purpose, for example, a device shown in a plan view in FIG. 1 and in a front view in FIG. 2 is used. That is, the thin wire (1) wound around the bobbin (2) passes through the fixed dancer roller (3) and the movable dancer roller (4) and is fed out in the direction of the arrow in the drawing. The movable dancer roller (3) can freely slide along the guide rail (5) and is always pulled in the opposite direction to the fixed dancer roller by a tension spring (6), which creates tension on the line. Given.

It is transmitted to the drive motor (9) of the output bobbin (2),
The wire payout speed is controlled by fully controlling the rotational speed of the bobbin (2) driven by the chain (11), and the tension of the wire is controlled by keeping the position of the moving dancer roller constant.

線の張力の変動の原因となる欠点がある。However, in this device, the tension spring (6) that pulls the moving side dancer roller (3) that applies tension to the wire increases or decreases the tensile force in proportion to the amount of elongation, and the position of the moving side dancer roller changes. The green tension also changes and a constant tension cannot be maintained. In addition, since the movement of the moving dancer roller is transmitted to the displacement detector via the rack and pinion (or a chain, etc.), a transmission loss occurs due to friction, which is caused by the movement of the moving dancer roller. becomes resistance,
It has the disadvantage of causing variations in wire tension.

、張力に影響を与えない。The movable dancer roller (3) can freely slide along the guide rail (5). On the other hand, a constant tension spring (A) is wound around the shaft of the displacement detector (2). The tip of this constant tension spring (A) is connected to the moving side dancer.
It is connected to the shaft of the roller (3), and the movable dancer roller (3) is always pulled in the opposite direction to the stationary dancer roller (4), and is tied to a wire under tension. As shown in Fig. 7, the constant tension spring (A) is a plate spring preformed into a coil shape.The coiled part is fixed to the shaft ◇, and one tip is stretched completely straight. The tip is used as a return spring. As shown in the drawing, when the tip of this constant tension spring is stretched by an amount Δ, the leaf spring in the coil portion is uncoiled in a straight line by an amount Δθ. When making a straight line, the unit length of the leaf spring in the coil part is correct. If the energy stored in the spring f is E, then if the entire tip of the constant tension spring is straight, the coil part will be stretched straight by r (radius of curvature) x △θ, so △Eoor△θ■△L, and △ E
= FX△L (where F - proportionality constant, force), so F
(force) - constant. The coil-shaped partial and total displacement detector (1) is fixed to the shaft (21) of the straight part (a), and the tip of the straight part (a) is fixed to the shaft of the dancer roller (3) on the moving side. The dancer roller (3) is always pulled with constant tension in the opposite direction of the fixed dancer roller (4).The tension of the tension is constant regardless of the position of the moving dancer roller (3). In addition, the displacement of the moving dancer roller (3) is directly transmitted as rotation of the shaft of the displacement detector by the coil part of the constant tension spring (A).In other words, the displacement of the moving side dancer roller (3) is directly transmitted to the displacement detector by the constant tension spring (A) itself. Displacement is transmitted, and there are no resistance factors such as frictional resistance in between, so it does not affect tension.

ものである。E1 Effects of the Invention As explained in detail above, the tension adjusting device of the present invention uses a constant tension spring to pull the movable dancer roller in the opposite direction to the fixed dancer roller in order to fully adjust the tension of the wire. , and the constant tension spring is engineered to directly rotate the shaft of the displacement detector, and the dancer roller displacement signal from the displacement detector is sent out to control the entire motor for driving the rotation of the bobbin? Which tension is fully adjusted, this allows the tension of the green to always be kept constant regardless of the position of the moving dancer roller, and the displacement detector is moved directly to the constant tension spring. Therefore, there is no transmission loss, and since it does not use a weight or the like, this adjustment device is an effective device with many features such as the performance is not impaired by centrifugal force even if it is installed inside the rotating body like a full petite netary type stranding machine. It is something.
