Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a multi-fiber spinning winding device.
・Recently, with the main purpose of improving productivity and saving energy, 'multiple yarns (often 8 or more) spun from one spinning position are taken up by the same Gopts roller, and in some cases After that, the fiber passes through an intermediate godet roller, is guided to a final godet roller, and is wound into multiple packages by a winding machine.

However, in multi-filament spinning, when a large number of threads (for example, four or more threads) are taken up with one winding machine, the following problems arise.

(There are restrictions on the spindle roller length or friction roller length of the ilK' machine due to the shape.6.It cannot be made infinitely long, and the number of threads becomes large.11) The length of the package to be stirred (traverse length) is 'Furthermore, if the yarn hook is made into a large package in order to reduce the number of operations, the diameter of the thread cage will become extremely large, making it difficult to transport the package.
Handling in post-processes such as inspections is the key to processing.゛(2) To cover the above-mentioned defects in package form.

A winding machine with the longest possible spindle roller or friction roller has a wide span between the two traverse supports at both ends, so a yarn path regulating guide is placed between the final roller and the winding machine. This is because the contact length and contact angle of the yarn are considerably different.

This causes a difference in the winding tension, which tends to cause a difference in yarn quality between each winding package.

Further, when a plurality of winding machines are used, although the problem of the shape of the rolled package in +11 above is improved, many problems such as the one-dimensional problem remain.

(b) Thread thread must be distributed to multiple winding machines, which inevitably complicates threading work, takes time, and generates a large amount of waste thread. When the yarn is distributed from the Godet roller to multiple winding machines, the contact angle of the yarn with the yarn path regulation guide during this time inevitably becomes an acute angle.

In severe cases, the threads may be damaged or problems may arise in which the single Φ thread is wound around each roller.

The inventors of the present invention have conducted extensive studies to improve these drawbacks, and as a result have arrived at the present invention, the gist of which is as follows.

In a multi-fiber spinning winding device in which an even number of four or more spun yarns are guided to the same final godet roller and equally divided into two winding machines for winding.

A multi-filament spinning winding device characterized in that the yarn winding rotation directions of the two winding machines are reversed and the yarn introduction surfaces of the two winding machines are opposed to each other.

According to the apparatus of the present invention, the difference in yarn quality between the pupil-up pancages is greatly improved, trouble-free and stable winding is achieved, and furthermore, threading into the winding machine becomes extremely easy.

Next, one embodiment of the present invention will be specifically explained with reference to the drawings.

FIG. 1 is a perspective view showing an example of the device of the present invention, FIG. 2 is a schematic front view of the device shown in FIG. 1, and FIG. 3 is a schematic front view showing a conventional device.

In the figure, 1 is yarn (multifilament yarn), 2 is the final godet roller, 3 is the lower fulcrum guide of the godet roller, 4
．． 4' is a traverse fulcrum guide, which is arranged on the center line of the traverse stroke. 5.5' is the main body of the winding machine, and one example shows a friction drive type winding machine with 8 windings. 6 is a traverse part of the winding machine, 7 is a friction roller, 8 is a bobbin support roller, 9
indicates a bobbin, and 10 indicates a package. Note that the arrow shown in Figure 9 indicates the yarn winding rotation direction.

The spun yarn 1 is guided to a final godet roller 2.

Godetstro? The package 1O is passed through the lower fulcrum guide 3 and the traverse fulcrum guides 4, 4' by the winding machines 5, 5'.
It is rolled up as. .

As shown in Fig. 3, in the conventional device, the yarn rotation direction of the two winding machines is the same, so when the two winding machines are arranged on the same plane, the traverse fulcrum guide 4. The distance between the winding machines ta5. ,)Is required.

On the other hand, according to the apparatus of the present invention shown in FIGS. 1 and 2, the two winding machines 5 and 5' have opposite yarn winding rotation directions and are arranged on the same plane. 2 machines to be rolled 15.5
' is in a positional relationship with the yarn introduction surface facing the
The separation between the traverse fulcrum guides 4 and 4' requires a space and a pace (symbol a in WJ) between the winding machines 5 and 5' in consideration of thread hanging work.

, Also, in the device of the invention, the lower fulcrum guide of the godet roller 3 to 1f! The angle (symbol θ in the figure) of the yarn vibration 5- to the two winding machines 5.5' becomes extremely small.

As a result, the contact length and contact angle of the yarn with the guide 3 and guides 4, 4' are reduced, compared to conventional ones.
The frictional resistance during this time is significantly reduced.

This results in achieving extremely uniform winding tension.

In addition, in the conventional device, the yarn introduction portions to the winding machines 5 and 5' are separated, which makes threading work complicated; Since the thread introduction parts can be brought very close to each other, the work of thread swinging is much easier than with conventional devices, and the work time of thread threading can be shortened.

It becomes possible to significantly reduce the amount of waste yarn generated before threading.

Furthermore, in conventional devices, the winding position requires a wide span, so at least two suction guns are required, and each suction gun is moved in the direction of each winding machine while threading is carried out. In some cases, multiple workers were required. However, according to the device of the present invention, the yarn introduction sections of two winding machines can be placed very close to each other, so one suction gun can be used to
Threading can be done quickly by hand, and automatic threading is extremely easy to do, as long as the threading is carried out to the shifter guide (not shown), which has a mechanism. can be moved to.

As described in detail above, according to the present invention, it is possible to achieve extremely uniform winding tension in multi-strand spinning, minimize the difference in yarn quality between stirring packages, and cause trouble. Stable winding is achieved without any problems, and the work of threading the thread into the winding machine is extremely easy and quick.

Although FIGS. 1 and 2 show a manual one-stop type winding machine, it goes without saying that the winding machine of the present invention may be of an automatic one-off type.

Note that the device of the present invention is advantageous when an even number of yarns of 4 or more are equally divided into two winding machines and wound.
For example, it can be applied to the case where an odd number of threads are wound by two winding machines in different numbers.

In addition, the device of the present invention is extremely effective in reducing the yarn quality difference between the formed pancages, especially when applied as a winding device for multi-filament spinning where the winding speed is high and it is difficult to adjust the winding tension difference. This shows the results.

0mm 4 package winding l112 units were used.

A polyester filament of 100 denier/24 filaments was wound at a winding speed of 4500 m/min.
Eight-strand spinning was carried out using the apparatus of the present invention shown in the figure and the conventional apparatus shown in FIG. A summary of the results is shown in Table 1.

Note that the distance between the supporting points in the device of the present invention is 10 cm.

The distance between the traverse supports of the conventional device was 60c+n, and the yarn path regulating guide and traverse guide from the final godet roller to the winding machine were of the same shape 1 surface roughness, material, etc.
