Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention winds a plurality of yarns having a high Young's modulus, such as glass fibers, aramid fibers, and metal fibers, simultaneously on a single spindle shaft. The present invention relates to improvement of a winding device in the field.

2. Description of the Related Art A technique for simultaneously winding a plurality of yarns on a single spindle is well known as disclosed in Japanese Patent Application Laid-Open No. 54-93143. This will be specifically described with reference to the drawings.

FIG. 5 is a side view showing a basic configuration of a conventional multi-thread winding device, and FIG. 6 is a front view of FIG. In FIGS. 5 and 6, the high Young's modulus, low elongation yarns Ya and Yb are subjected to a predetermined process (not shown) to become a final form of yarn and sent to the winding device. It travels to the traversing device 4 of the winding device via the tension detecting device 5 via the guide roller 11. The yarn traversed by the traverse device 4 is formed as packages 2a and 2b on the spindle 1 via the roller bale 3.

If it is higher than the predetermined winding tension value, the rotation number of the drive motor 6 of the spindle 1 is reduced via the tension controller 8 by the signal of the tension detection output unit 7 of the tension detecting device 5 to reduce the winding tension value. Is controlled to a predetermined value. At this time, since the two yarns Ya and Yb are engaged with one tension detecting device 5, if the yarn feeding tensions from the respective processes are different for some reason, the respective yarns are wound by a predetermined winding. You are not under tension.

If the yarns Ya and Yb have different tensions, the average value thereof represents the winding tension value and acts. Therefore, if the deviation between them becomes large, either or both package forms will not be formed well.

However, when a plurality of yarns having a high Young's modulus and a low elongation are wound simultaneously on a single spindle by using the above-described apparatus, the yarn forming process between the plurality of yarns and the yarn running during the yarn running are required. Variations in the generated thread tension Variations in the traverse width between the winder traverse devices Due to variations in the pressing force pressing the packages during package formation, etc., morphological differences occur between the multiple packages formed on the spindle, In many cases, a situation may occur in which a yarn layer is broken in another package and a normal package form cannot be obtained with respect to a reference yarn for actually detecting and controlling the tension. Alternatively, inconveniences such as breakage of the yarn layer and breakage of the yarn are liable to occur at the time of handling and transporting the package obtained at the time of shipping and transport, and during the subsequent process of using the product.

Therefore, at present, when winding such a high Young's modulus and low elongation yarn, it is necessary to use an independent winding device for each yarn enduring an increase in cost, or to reduce the equipment cost. Either using a multiple yarn winding device according to the prior art, knowing that the operation yield is low from the purpose, or a desirable state of "low equipment cost and high yield of the obtained package" It is free from

[Problems to be Solved by the Invention] The present invention is intended to solve the above-mentioned conventional technology, and a plurality of yarns can be simultaneously wound on one spindle, even if the yarn has a high Young's modulus and a low elongation. It is an object of the present invention to provide a yarn winding device capable of winding a package without any bearing during a normal process.

[Means for Solving the Problems] That is, the present invention relates to a winding device for winding a plurality of yarns on one spindle shaft, wherein each of the yarns has a yarn tension detecting unit, at least one of which is provided. A yarn used for controlling the number of revolutions of a spindle shaft, wherein the other yarn tension detecting units each control a traverse width of a traverse device for forming a package of a yarn passing through the detecting unit. It is a winding device.

 Hereinafter, the present invention will be described with reference to the drawings.

FIG. 1 is a front view showing an example of the yarn winding device of the present invention.

In FIG. 1, 1 is a spindle, 2a and 2b are packages, 3 is a roller bale, 4a and 4b are traverse devices, 5a and 5b.
Is a tension detection device, 6 is a drive motor, 7a and 7b are tension detection output units, 8 is a tension controller, 9 is a traverse width controller, 10 is a traverse width control drive device, and Ya and Yb are yarns.

The two yarns Ya and Yb pass through tension detectors 5a and 5b, respectively.
It is sent to the traverse devices 4a, 4b. At this time, the tension detecting devices 5a and 5b are independent of each other, and
The number of rotations of the drive motor 6 of the spindle 1 is controlled via the tension controller 8 by a signal from 7a.

On the other hand, based on a signal from the tension detection output unit 7b of the tension detection device 5b, a traverse width control driving device 10 (not specified by a motor, a cylinder, etc.) via a traverse width controller 9
To change the winding width of the package 2b by increasing or decreasing the traverse width of the traverse device 4b.

As the traverse device 4b, a system as disclosed in, for example, JP-A-48-64240 is preferably applied. This will be specifically described with reference to the drawings. 2 to 4 are views showing one example of a traverse device according to the present invention. 4 to 6, the traverse guide arm 41 has an L-shape, and a central fulcrum portion 42 is rotatably supported by an engagement portion 44 engaged with the traverse cam 43. A traverse guide that has an engaging portion 44 at one end of the traverse guide arm 41 engaged with a swing rail 45 that can swing with respect to the axis of the traverse cam 43, and guides the yarn to the other end. It has a part 46. By the operation of the traverse width control drive device 10, the angle of the swing rail 45 with respect to the axial direction of the traverse cam 43 changes, and therefore, the inclination of the traverse guide arm 41 also changes, so that the traverse width can be changed.

With respect to the two yarns Ya and Yb sent out, the rotational speed of the spindle 1 is controlled by using the Ya-side yarn tension control value as a standard value.

On the other hand, when the tension value of the Yb yarn is lower than the standard value, the output value from the tension detection output unit 7b of the tension detection device 5b,
The traverse width control driving device 10 is operated by the operation of the traverse width controller 9, and the traverse cam 43 shown in FIG.
The angle α between the axial direction and the swing rail 45 becomes smaller,
The traverse width becomes narrow. For this reason, the diameter of the package 2b increases quickly, and the winding tension value increases, approaching the standard tension value. When the tension value of the yarn Yb is higher than the standard value, the reverse operation is performed. At this time, if the value of the variation amount of the traverse width and the sensitivity are set to appropriate amounts by applying a well-known control theory based on the deviation amount of the tension value of the yarn Yb from the standard value, the winding amount of Yb The tension value can be controlled sufficiently well without frequently hunting up and down with respect to the standard value.

As a result, even if the tension between the two yarns is for some reason,
For example, even if the denier (thread thickness) is different or the difference is due to the difference in tension loss in the guide etc. in the middle, the winding tension between the two is completely within the allowable range after entering the winding device. And the formation state between the two packages is good in both cases, and the occurrence of shape collapse, defects in operation handling, and the like is extremely reduced.

The present invention is not limited to the case of two yarns as in the above-described embodiment, and can be similarly applied to the case of two or more yarns.

[Effect of the Invention] By implementing the present invention, it is possible to wind all of the yarns sent out by a plurality of packages in a good package.

 Therefore, the product yield is significantly improved as compared with the conventional case.

 Product costs are reduced.

Since the variation in the yarn forming process is absorbed in the winding process, the difficulty in the yarn forming process, which has been regarded as a problem in the past,
For example, there is a very great effect that the problem is solved when the denier deviation tolerance becomes larger than before, which is a number of conventional methods.
