Description

[Detailed description of the invention] (Industrial application field) This invention uses a warp sizing machine that arranges a large number of warp threads for textiles in a sheet shape, glues them, and dries them. This invention relates to a size box for impregnating warp glue.

(Prior Art) As a size box for a warp sizing machine, one shown in FIG. 2 is known. That is, the immersion roller 2, the first bottom roller 3a, and the second bottom roller 4a are arranged in order from the rear of the size box 1 toward the front, and the immersion roller 2, the first bottom roller 3a, and the second bottom roller 4a are arranged on the upper surface of the first bottom roller 3a and the second bottom roller 4a, respectively. A first squeegee roller 3b and a second squeegee roller 4b are provided, and a large number of warp yarns T lined up in a sheet drawn from a warping beam (not shown) at the rear (right side of the figure) are placed in a size box 1. It is guided into the size box 1 from the entrance guide roller 5 above the rear end, immersed in the size liquid S by the immersion roller 2, and then transferred to the first bottom roller 3.
The material is sequentially passed through the nip between the roller a and the first squeegee roller 3b, and the nip between the second bottom roller 4a and the second squeegee roller 4b, and then sent to the front drying section.

(Problem to be solved by the invention) Conventionally, since the warp yarn T ran along a substantially horizontal straight line between the first bottom roller 3a and the second bottom roller 4a, the second bottom roller 4a A part of the size liquid Sa that adheres to the surface and is lifted up as it rotates accumulates on the warp threads T behind the nip part P of the second bottom roller 4a and the second squeegeeing roller 4b, and The fly fluff separated from the warp yarn T is mixed into the size liquid Sb, and this gradually grows and becomes larger, and this grown fluff adheres to the surface of the second squeezing roller 4b, and then re-attaches to the warp yarn T. It is dried and wound around a beam for a loom while being firmly fixed to the warp threads T, resulting in a problem that thread breakage occurs during the weaving process. Also, the above size liquid accumulated on the warp threads T
Since the Sb tends to flow from the center in the width direction to both left and right sides, the warp yarns T at the ears are pushed outward, causing a problem in that the warp yarns T are misaligned. In addition, these problems can be overcome in recent years when high-concentration sizing liquid is used and squeezed under high pressure, sizing machines operate at high speeds, and fabrics with a high warp density are woven. It became more and more noticeable.

This invention is based on the warp yarn T behind the nip portion P of the second bottom roller 4a and the second squeezing roller 4b.
This prevents the size liquid Sb from accumulating on the top, thereby suppressing the growth of fluff and reducing thread breakage in the loom, as well as preventing the occurrence of alignment defects at the selvedges.

(Means for Solving the Problems) As shown in FIG. 1, an intermediate guide roller 6 in the width direction is provided slightly above a straight line connecting the upper surfaces of the first bottom roller 3a and the second bottom roller 4a. The warp threads T lined up are bent into a chevron shape.

(Function) First bottom roller 3a and second bottom roller 4a
When the warp yarns T between the two are passed through the upper surface of the intermediate guide roller 6, the warp yarns T are bent into a mountain shape by the intermediate guide roller 6, and a contact angle θ between the warp yarns T and the second squeezing roller 4b is created. . Therefore, the wedge-shaped space conventionally formed on the warp threads T behind the nip portion P between the second bottom roller 4a and the second squeezing roller 4b disappears, and the entire amount of squeezed out size liquid is transferred to the second bottom roller. The size liquid Sb returns to the size box 1 along the surface of the roller 4a, and the size liquid Sb does not accumulate on the warp threads T.
No fly fluff grows on the top, and no fly fluff adheres to the second squeegeeing roller 4b. Since the warp threads T contact the second squeezing roller 4b and the intermediate guide roller 6 at the above contact angle θ, the restraining force on the warp threads T increases,
Moreover, since the size liquid Sb does not accumulate on the warp threads T,
There is no force pushing the warp threads T of the ears outward.
Note that the intermediate guide roller 6 described above may be one that is actively rotated. Further, the mounting height can be freely adjusted and adjusted by the type of warp threads T and the concentration of size liquid S.

(Example) As shown in FIG. 1, a size box 1 includes a passively rotating immersion roller 2, an actively rotating first bottom roller 3a, and a second bottom roller 4a.
are sequentially provided on the upper surfaces of the first bottom roller 3a and the second bottom roller 4a, respectively.
The squeegee roller 3b and the second squeegee roller 4b are connected to an air cylinder (not shown).
In a device that presses the first bottom roller 3a and the second bottom roller 4a, the center distance between the first bottom roller 3a and the second bottom roller 4a is
13.5 cm, and an intermediate guide roller 6 with a diameter of 6 cm is rotatably installed above the intermediate guide roller 6 at a height of 2.6 cm above the horizontal line connecting the top surfaces of the bottom rollers 3a and 4a. Good results were obtained by bending the warp threads T into a chevron shape between them and the bottom roller 4a.

(Effect of the invention) In this invention, an intermediate guide roller is provided between the first and second bottom rollers, and this guide roller bends the warp threads in a chevron shape. and the warp yarn behind the nip portion of the second squeegee roller contacts the lower surface of the second squeegee roller at a certain angle,
Size liquid does not accumulate on the warp yarns at the rear of the nip, unlike in the conventional case. Therefore, the fly fluff mixed in the size liquid on the warp yarns does not grow large and adhere to the warp yarns T as in the past, and the occurrence of yarn breakage in the loom is reduced. Furthermore, since the size liquid does not accumulate on the warp yarns as described above, the warp yarns at the selvedges do not break due to the flow of the size liquid accumulated on the warp yarns and cause poor alignment, unlike in the conventional case. Moreover, since the warp threads pass over the upper surface of the intermediate guide roller, the warp threads are not hidden and are easy to handle.
