Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a warping method in a partial warper that warps warp yarn from a creel and a yarn length measuring device used therefor.
[0002]
[Prior art]
Conventionally, as shown in FIG. 7, the warping method of this type of warp is such that the creel a fixed to the floor surface and the warp drum b can be moved in the axial direction on the floor surface in front of the creel a. Warping composed of a partial warping machine c provided, and a twilling iron d provided between the creel a and the partial warping machine c and movably provided in the axial direction of the warping drum b. The system is used.
[0003]
Specifically, the warp W from the creel a is bound to the warping drum b via the treading ridge d, and the warp drum b is rotated to wind the warp W.
[0004]
Specifically, the warp W wound around the warping drum b is a cone of the warping drum b, and a width determining rod e disposed just before the warping drum b is used so that the yarn layer WA is a parallelogram. It is wound around the warping drum b while being obliquely fed in parallel with the angle of the part f.
[0005]
However, since the yarn width of the multiple warp W fed from the creel a is wide at the weaving kite d, while the yarn width of the multiple warp W wound around the warping drum b is narrow, the weaving kite d The warp W1 and the warp W2 running on both sides of the warp W2 are almost in the same bent state at the initial warping, so the tension of both is the same. By moving, the bending state between the warp W1 and the warp W2 changes, causing a difference in tension. Various factors such as the work environment of the warp W, the temperature and humidity, the static electricity generated in the warp W, etc. As a result, as shown in FIG. 8, a phenomenon occurs in which the thickness on the left side (cone portion f side) of the yarn layer WA is reduced. Therefore, the thickness of the yarn layer WA is measured by visual inspection by an operator. Based on this, adjust the feed amount Because you are adjusted so made the yarn layer WA and parallelogram by eliminating the above-mentioned phenomenon, or requires skill, workability is required is adjusted for each KakuSeikei had a bad disadvantage.
[0006]
[Problems to be solved by the invention]
The present invention relates to a warping method in a partial warping machine which automatically warps warps uniformly and uniformly so as to form an accurate parallelogram yarn layer regardless of the skill level of the operator, and The present invention relates to a yarn length measuring device used for it.
[0007]
[Means for Solving the Problems]
In view of the problems such as poor workability based on the above-mentioned conventional technology, the present invention measures the yarn length with several warp yarns running on both sides of the warp band before passing through the twill coat, and the difference between the two yarn lengths To eliminate the above-mentioned drawbacks by providing a warping method in a partial warping machine and a yarn length measuring device used for it It is a thing.
[0008]
In addition, as a yarn length measuring device in the partial warper used in the above warping method, rotation control of the warping drum and movement control of the width deciding mechanism according to each section warping, Use a partial warper to warp the warp of the yarn, provide a twilling ridge between the creel and the partial warping machine, and contact with several warps on both sides of the warp band before passing through the twilling ridge A yarn length measuring instrument equipped with a rotating pulley is provided.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
As the warping system 1 for partially warping the warp W, a creel 2 for supplying a large number of warps W is fixedly provided, and in front of the creel 2 in the feed direction of the warp W, a cylindrical portion 3 and A partial warping machine 6 for controlling the rotation of the warping drum 5 composed of the skirt-shaped cone portion 4 at a desired rotational speed is provided. The partial warping machine 6 is provided so as to be movable in the axial direction of the warping drum 5. It has been.
[0010]
Reference numeral 7 denotes a width determiner. The width determiner 7 is provided in the vicinity of the circumferential surface of the warping drum 5 and is controlled to move in the axial direction of the warping drum 5 at a desired speed. It is mounted on a moving body 8 that is controlled to move at a desired speed parallel to an oblique direction corresponding to the inclination angle of the cone portion 4.
[0011]
Reference numeral 9 denotes a treading iron. The treading iron 9 is disposed between the creel 2 and the partial warping machine 6 and is provided so as to be movable in the axial direction of the warping drum 5.
[0012]
Reference numeral 10 denotes a yarn length measuring device. The yarn length measuring device 10 comes into contact with several warp yarns W on a yarn length sensor 11 composed of a tachometer and an encoder that outputs a signal proportional to the number of revolutions, and friction with the warp yarns W is obtained. A small, lightweight pulley 12 that rotates with force is attached.
[0013]
In the figure, reference numerals 13 and 13a denote auxiliary pulleys for always contacting the warp W with the pulley 12.
[0014]
The yarn length measuring device 10 is provided on both sides of the warp yarn 9 on the upstream side of the warp yarn W feeding to form the yarn length measuring device 14.
[0015]
Thus, by providing the yarn length measuring device 10 on the upstream side of the warp W feeding, the other adjacent warp W and the pulley 12 are not brought into contact with each other.
[0016]
The pulley 12 is rotated by a frictional force with the warp W, and when the warp W feed is stopped, the pulley 12 is also stopped quickly.
[0017]
Next, for the warping method in the partial warping machine according to the present invention,
A large number of warps W from the creels 2 are bound to the warping drum 5 via a treading rod 9 and a width determining rod 7, and are attached to pulleys 12 of a yarn length measuring device 10 provided on both sides of the twilling rod 9. Winding so that several (about 2 to 5) warps W located on both sides of a warp band composed of a large number (about 300 to 1000) of warps W before passing through the twill coat 9 are brought into contact with each other. Let
[0018]
The warping drum 5 is rotated at a desired number of rotations for each section warping, and the moving body 8 is obliquely laterally parallel to the cone portion 4 of the warping drum 5 with a feed amount corresponding to the type of the warp W in advance. By winding the warp W around the warping drum 5 while being moved, the cross-sectional shape of the yarn layer WA composed of the warp W is formed into a parallelogram.
[0019]
As described above, as a warping method, the warp W is wound around the warping drum 5 for each section. However, as shown in FIG. 3, in the present invention, the number of windings on the warping drum 5 is a predetermined value. At the time points T1, T2, and T3, the warp band measured by the yarn length measuring device 10 on the left side (cone portion 4 side) and the yarn length measuring device 10 on the right side (cylinder portion 3 side) of the yarn length measuring device 14 is measured. When the warp W is wound by adjusting the feed amount of the moving body 8 in accordance with the difference in yarn length between the warp yarns W1 and W2 on both sides, and after further winding a predetermined number of times, the width determining rod 7 is slanted by the moving body 8. Due to the lateral movement, there is a further difference in the tensions of the warp yarns W1, W2 on both sides of the warp band, and there is also a difference in the yarn length. After that, the yarn length measurement is repeated for each desired number of rotations, and the moving body 8 Ri amount was adjusted for each measurement ultimately wind the cross-sectional shape of the yarn layer WA As becomes a parallelogram.
[0020]
The above warping is an explanation of the initial section warping, but after the second section warping when the warp drum 5 is subjected to a plurality of section warping, the yarn length obtained by the initial section warping is the same. The difference and the feed amount of the moving body 8 are stored in a control device 15 such as a sequencer or a computer, and the second section warping and the like are similarly performed based on such data.
[0021]
【The invention's effect】
In short, the present invention is a warping method in a partial warping machine that warps a large number of warps from a creel by controlling the rotation of a warping drum and controlling the movement of the width warp according to each section warping. The yarn length is measured with the warp yarns W1 and W2 on both sides of the warp band before passing through the treading ridge 9 disposed between the creel 2 and the partial warper 6, and the width is determined according to the difference between the two yarn lengths. Since the amount of movement of the reed 7 is controlled, the difference in the yarn length that occurs when the width 7 is moved during aging is maximized, and the warp W1 and W2 at locations where the feed (bending) state does not change. Therefore, since the yarn length is measured, it is possible to reliably cope with slight changes on the side of the cone portion 4 of the yarn layer WA, and because the yarn layer WA is not measured by contact except for both sides of the warp band. The warp can be warped without changing the center side, and even if the type of warp W is different It can support, thus easily without requiring skill as in prior art, can be warped to and automatically correct plies WA.
[0022]
In addition, since the yarn length measuring device 10 equipped with the pulley 12 that rotates in contact with several warp yarns W1 and W2 on both sides of the warp band before passing through the twill coat 9 is provided, several warp yarns W and Since the pulley 12 rotates with the frictional force of the yarn, the yarn length measuring device 10 can be made smaller and lighter, and can follow even when the winding speed is increased, and the rotational loss due to slip is reduced, so that the accurate yarn length is reduced. As a result, the adjustment of the yarn layer WA becomes accurate, and the pulley 12 is small and light, so the inertial force is small and the pulley 12 does not run idle even when winding is stopped, and the total yarn length during aging is also accurate. Its practical effects such as being measurable are enormous.
