DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flyer device used when unwinding a yarn from a package or when untwisting and twisting a package.

This conventional flyer is configured to rotate by the tension of a yarn unwound from a package, and is of a so-called depolarization drive system (free rotation system).

[0003]

In the conventional flyer of the depolarizing drive system, when the unwinding position (unwinding point) of the yarn in the package is shifted to the upper side, the unwinding tension is low and the yarn is unwound. When the unwinding position is shifted to the lower side, the unwinding is performed while rubbing the surface of the package, so that the unwinding tension increases, and further, at a stage where the winding diameter of the package is large, the unwinding tension is low. However, as the winding diameter of the package becomes smaller, the unwinding tension increases, and fluctuation of the tension during the unwinding period of the yarn has been pointed out as a major problem.

As described above, if the tension fluctuates when the yarn is unwound, the balloon expands when the tension is low. For example, in a quadruple twisting machine, the inner balloon and the outer balloon come into contact with each other, and the yarn breaks. Had become a major cause.

Further, when the yarn is unwound from the package, the unwound yarn is unwound while being rubbed against the outer layer of the package. It was with.

Accordingly, the present invention is to solve the above-mentioned problems which have been pointed out in the prior art. By directly connecting a rotary drive source to the flyer, the flyer is actively activated in synchronization with the yarn unwinding speed. The flyer device is designed to suppress the fluctuation of the tension, suppress the fluctuation of the balloon, and suppress the cause of the yarn breakage regardless of the yarn unwinding positions on the upper and lower sides of the package and the winding diameter of the package. To provide.

[0037]

According to the flyer apparatus of the present invention having the above structure, it is possible to drive the flyer at an optimum rotation speed for unwinding the yarn, and even if the yarn is suddenly rotated, the yarn can be driven. Since the flyer rotates following the above, the yarn can be unwound without giving excessive tension to the yarn, and the yarn breakage can be prevented as much as possible.

Further, according to the flyer apparatus of the present invention, the power source of the motor M3 in the third rotary drive system component for positively driving the flyer is rotated by the power generation means by the rotary drive of the twisting machine itself. It can be said that the configuration in which power is supplied works very effectively also in that the operation cost can be reduced.

Furthermore, according to the flyer device of the present invention, when unwinding the yarn wound at the lower part of the package, the yarn is unwound so as to peel off the yarn by the flyer device, so that the yarn is wound around the package surface. Compared with the conventional unwinding method in which the unwound yarn is unwound, it is possible to prevent the fluffing of the yarn, and it is extremely effective in that the balloon is stabilized without fluctuating. Further, in the quadruple twisting machine in which the inner balloon IB and the outer balloon OB are formed, contact between the inner balloon IB and the outer balloon OB due to a change in tension during unwinding can be prevented, and yarn breakage can be prevented. It can be said that it also works extremely effectively in the points that can be performed.
