DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a yarn waxing apparatus for attaching wax to a running yarn.

[0002]

2. Description of the Related Art Conventionally, a waxing device for attaching a wax to a yarn has been provided on a yarn path of a yarn wound into a package by an automatic winder for the purpose of reducing frictional resistance of the yarn and suppressing fluff. I have. FIG. 4 shows an automatic winder provided with the waxing device. The automatic winder 1 has a traverse drum 3 in which traverse grooves 2 are engraved, drives and rotates a package 4 to rotate a package 4 and a yarn 5 unwound from a yarn supplying bobbin (not shown), a tensor drum 6 and a waxing device. It is wound around the package 4 while traversing via the yarn guide 7a and the yarn guide 8.

As shown in FIG. 5, the waxing device 7a includes a wax 9 arranged so as to sandwich the yarn 5 (yarn path).
a and a disk 10a. The disk 10a is fixed to the rotating shaft 11a, and rotates integrally with the rotating shaft 11a. The wax 9a is formed in a cylindrical shape,
It is inserted through the rotating shaft 11a, is rotatably supported, and is pressed against the disk 10a by the air cylinder 12a. The rotating shaft 11a is rotated by a motor (not shown) while the yarn 5 is wound around the package 4.

According to the waxing device 7a, the yarn 5 sandwiched between the wax 9a and the disk 10a is
The wax 9a pressed against the disk 10a by the air cylinder 12a rotates with the rotation of the disk 10a, so that the wax is attached to the surface while passing between the wax 9a and the disk 10a, and waxing is performed.

[0005]

However, as described above,
When the wax 9a is set to the moving side and the disc 10a is set to the fixed side, and the wax 9a is pressed against the disc 10a by the air cylinder 12a and waxed, the pressing load of the air cylinder 12a decreases as the wax 9a decreases and its weight changes. Is lighter, so the wax 9a thread 5
Fluctuates (increases).

That is, the pressing force of the air cylinder 12a is based on the condition that the wax 9a is brand new and has not been reduced at all and is in the heaviest state (when the pressing load is the largest).
Since the wax 9a is set to be sufficiently attached to the yarn 5, if the weight of the wax 9a is reduced and the weight is reduced, the pressing force becomes excessive and wasteful consumption of the wax 9a occurs. The pressing force of the air cylinder 12a is constant.

SUMMARY OF THE INVENTION An object of the present invention, which has been devised in consideration of the above circumstances, is to provide a yarn waxing apparatus capable of keeping the amount of wax adhered to a yarn irrespective of the decrease in the amount of wax and suppressing wasteful consumption of wax. To provide.

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention relates to a yarn waxing apparatus in which a wax and a disc are arranged so as to sandwich a yarn path, and a fixing means for holding the wax in a predetermined position. And pressing means for pressing the disc against the wax.

In the present invention, since the disc is pressed by the pressing means against the wax whose position is held by the fixing means, the weight of the moving disc changes even if the wax on the fixed side is consumed. Therefore, the pressing load of the pressing means does not fluctuate. Therefore, the amount of wax adhering to the yarn can be kept constant irrespective of the decrease in the amount of wax, and wasteful consumption of wax can be suppressed.

[0010] The fixing means may comprise a lever for urging the wax toward the yarn path, and a stopper abutting against the front end surface of the wax.

According to this configuration, as the wax is reduced, the wax is pressed toward the yarn path by the lever, and the tip surface thereof is positioned in contact with the stopper, so that the position of the contact portion of the wax with the yarn path is changed. It is constant regardless of the decrease. Therefore, the amount of wax attached to the yarn and the amount of consumption are stabilized.

Further, the pressing means may comprise a fluid cylinder.

According to this configuration, by adjusting the pressure of the fluid cylinder, the pressing force for pressing the disk against the wax by the pressing means can be adjusted, so that the amount of the wax attached to the yarn and the consumption amount can be easily changed.
