Description

[Detailed description of the invention] <Industrial field of application> The present invention relates to a device for applying oil to synthetic fibers, and more specifically to a device for applying oil to synthetic fibers spun from a spinneret after cooling them in a spinning tube. It is something.

<Prior Art> Conventionally, in order to apply a lubricant to a synthetic fiber thread (hereinafter referred to as yarn), a device is known in which a running yarn is brought into contact with, for example, an oil supply roller whose surface is coated with a coat of lubricant. Furthermore, Japanese Utility Model Application Publication No. 139711/1989 describes an apparatus for traversing a running yarn while the running yarn is brought into contact with an oil supply roller having a film of oil adhered to its surface.

<Problems to be solved by the invention> When applying oil to running yarn using a lubricating roller, the fineness of the yarn, the number of single yarns, the disturbance of the air flow accompanying the yarn, and the aggressive left and right direction of the lubricating roller The position and area of the yarn in contact with the oil supply roller surface changes due to movement to the surface of the oil supply roller, resulting in uneven yarn quality.

In order to compensate for this drawback, a method has been adopted in which a yarn width regulating guide is provided above the oil supply roller to forcibly change the yarn width so that the yarn comes into contact with the oil supply roller surface by an appropriate width. If a roller is used, not only the quality of the yarn deteriorates due to contact between the guide and the yarn, but also the yarn is forced to be positioned in the center of the oil supply roller, and when pulled, single yarn breakage may occur.

In addition, in the case of the device described in the above-mentioned Japanese Utility Model Publication No. 54-139711, although the yarn contact area can be narrowed, it cannot be expanded. This method has the disadvantage that the quality of the yarns cannot be made uniform in the longitudinal direction due to disturbances such as overlapping and crossing of the single yarns forming the yarns.

The purpose of the present invention is to improve the drawbacks of the conventional apparatus, and to make the oil supply roller and trough movable, and to adapt to variable conditions such as yarn brand, fineness, spinning speed, oil properties, and oil application fee. The yarn can be fixed in the best position by adjusting the center of the yarn and the lubricant applying device, and the variation in the contact area with the lubricating roller based on the variable conditions can be corrected, and the lubricant can be uniformly applied to the yarn. It is.

<Means and effects for solving the problems> The configuration of the present invention is such that, in an oil application device provided below a spinning tube that cools melt-spun synthetic fibers, the oil supply roller and trough of the oil application device are A variable position mechanism movable in at least one of the vertical and horizontal directions and a mechanism for fixing the refueling roller and trough whose positions have been changed by the variable position mechanism are provided, and the refueling roller and trough are fixed. The synthetic fiber lubricant application device is characterized in that a focusing guide for focusing the synthetic fibers supplied with oil downward is provided, and the contact pressure between the synthetic fibers and the oil supply roller can be adjusted.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a side view of an example of a lubricant application device according to the present invention, and FIG. 2 is a side view of the device shown in FIG. 1.

In the figure, 1 is a spinning tube that cools the yarn, 2 is a yarn width regulation guide, 3 is an oil supply roller, 4 is a yarn, and 5
is a tightening bolt, 6 is a focusing guide, 7 is a trough, 8 is a holding bolt, 9 is a drive motor, 1
0 is a spacer.

After the melt-spun yarn 4 is cooled by the spinning tube 1, it comes into contact with the surface of the rotating oil supply roller 3 and is applied with an oil agent. It does not necessarily pass through the center of the oil supply roller 3, and this varies depending on the denier of the yarn 4, the single yarn denier, the number of single yarns, the cooling conditions in the spinning tube 1, etc., and it is recommended to increase the width of the oil supply roller 3. Lubricate the yarn with roller 3
can be passed through approximately the center of However, in this case, as the refueling roller 3 becomes larger, the trough 7
The size of the tank also increased, and the oil in the trough 7 gelled.
Not only does this impede smooth operation, but the quality of the obtained yarn 4 becomes abnormal and it cannot be used as a product.

Although it is desirable to make the width of the oil supply roller 3 narrower in order to eliminate these drawbacks, by making the width narrower, the yarn 4 becomes easier to come off from the oil supply roller 3.

In order to solve this problem, a spacer 1 is provided so that the thread 4 can run in the center of the oil supply roller 3.
By changing the insertion amount of 0, the left and right direction of the oil supply roller 3,
That is, it is corrected in the same direction as the contact surface of the oil supply roller 3. Also, move the trough 7 in the left and right direction,
This can also be done by using a spacer (not shown) when fixing.

The contact area between the oil supply roller 3 and the thread 4 is corrected by loosening the tightening bolts 5 and 8 and moving the position of the oil supply roller 3 and the position of the trough 7 in the vertical direction, and then tightening and fixing the tightening bolts 5 and 8. do. That is, the oil supply roller 3 and the trough 7 are moved by a variable position mechanism and then fixed by a fixing mechanism. The contact pressure between the yarn 4 and the oil supply roller 3 is adjusted by lengthening or shortening the distance between the oil supply roller 3 and the focusing guide 6 provided below the oil supply roller 3. The contact pressure between the yarn 4 and the oil supply roller 3 varies depending on the denier of the yarn 4, the single yarn denier, the number of single yarns, the cooling conditions, etc. It is not a steady state of high or low pressure, but depending on the characteristics of the yarn 4 or cooling conditions, the longer it is, the higher the pressure is, or the shorter it is, the higher the pressure is. Initially, the positions of the oil supply roller 3 and trough 7 are corrected and fixed at optimal positions. In this case, the yarn width regulating guide 2 does not have the function of forcibly changing the width of the yarn 4, and when the width of the yarn 4 changes greatly, it lightly contacts the yarn 4 and controls the yarn of the three oil supply rollers. It has the function of keeping the width of 4 constant.

Once the oil supply roller 3 and the trough 7 are straightened and fixed with the tightening bolts 5 and 8, they do not move vertically or horizontally during operation.

As mentioned above, the synthetic fiber lubricant application device according to the present invention reduces the contact pressure between the yarn 4 and the oil supply roller 3 by changing and fixing the thickness of the spacer 10 and the tightening positions of the tightening bolts 5 and 8. Adjust.

<Effects of the invention> According to the invention, the oil supply roller and trough are movable and can be fixed after being moved, so that they can be adjusted depending on the spinning brand, fineness, single yarn tenier, cooling conditions, spinning speed, etc. Due to the deviation of the center position and the variation of the contact area between the yarn and the oil supply roller that occurs, the oil supply roller and trough can be moved and adjusted to the optimal position and fixed. As a result, the yarn can be fixed on the oil supply roller This has the effect of significantly reducing crossover and overlapping of each single yarn, uniformly applying the oil agent in a stable state, and stabilizing the quality of the resulting yarn.
