JPH03186568A - Taking-up of bound spun yarn - Google Patents

Abstract

PURPOSE:To carry out taking-up for convenience of the main usage of a bound spun yarn by introducing two single yarns which are spun in a pair of spinning parts of a two-ply binding spinning machine to a taking-up device without binding both the yarns and taking up the yarns as a pair of cheese to a taking-up bobbin held by a single cradle. CONSTITUTION:Two binding yarns Y1 and Y2 which are spun out from spinning units 1a and 1b are taken out as they are to a delivery roller 4 and sent into a taking-up device 7. The yarn Y1 is traversed by a traverse guide 8a, and the yarn Y2 is traversed by a traverse guide 8b, and each traverse range of both the traverse guides 8a and 8b is set so as not to be superposed, and both the yarns Y1 and Y2 are taken up to the different positions on a single bobbin 9, and the packages P1 and P2 are formed, and a pair of cheeses P are formed. The cheese P is used as it is for the supplied thread in the upper and lower stages of a double twister, while if the bound yarn is used as the weft of the no-defraying fiber, the winding starting part of the yarn of one package is joined with the winding edge of the yarn of the other package.

Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to a method for winding bundled spun yarn.

[Conventional technology]

In a two-ply binding spinning machine, two systems spun from each of two spinning units installed close to each other are usually combined immediately after spinning and wound up as a single package. On the other hand, tied spun [1 yarn is often used after being heated using a double twister after the gold thread, or used as a single yarn as a weft in a loom. Problem 1 to be Solved by the Invention K The purpose of the present invention is to provide a winding method for obtaining a bundled spun yarn package that is conveniently wound for any of the above-mentioned uses of the bundled spun yarn. The goal is to provide a method for [Means for Solving Problem 1] Two single yarns spun by a pair of spinning sections in a two-ply binding spinning machine are guided to a winding device without doubling, and the winding device is held by a single cradle. Roll it up on a bobbin as a pair of cheeses. In a two-ply binding and spinning device that implements this winding method, the doubling guide provided immediately after the pair of spinning units is eliminated, the traverse guide in the winding device is made into two, and the spun yarn is Make sure they run parallel to each other until they reach the traverse guide. That is, a slack tube, a slab catcher, etc., which are normally provided between the spinning unit and the winding device, run two yarns without being combined, so two yarn rows are formed. r Effect] The winding method of the present invention winds the bundled spun yarn produced by the two-ply spinning device into a pair of cheeses on one winding shaft without doubling. Since two packages are formed on a bobbin that can be divided into two,
The width of each individual package is approximately 1/2 that of the case when the package is rolled up into a single package, but it is possible to set two packages above and below on a double twister, which is a so-called sun package, and heat the yarn while it is being twisted. This provides a pair of binding thread packages that can be directly set in the double twister when the double twister is used. Furthermore, even when unpaired binding yarn is required, such as the weft yarn of a shuttleless loom, the package can be used as a single yarn by pulling out the yarn from each package wound up in pairs. K Embodiment Next, the method of the present invention will be explained along with an example of an apparatus for carrying out the method of the present invention. The drawing shows a 2-ply bound spinning machine that implements the winding method of the present invention.
FIG. 2 is a perspective view showing the main parts of the device. Following a drafting device (not shown) for simultaneously drafting two slivers,
The sliver S1. drafted by the draft device. S
A spinning section 2 having a pair of spinning units 1a and 1b for spinning 2 is provided. Inside the spinning section 2, there is a cutter for trimming the yarns at the start of splicing. These are not particularly different from those of a normal two-ply spinning device. At the bottom of the spinning section 2, there is no doubling guide like in a normal 2-ply spinning device, and yarn breakage sensors 3a and 3b are installed in order from the top.
, delivery roller 4, slack tubes 5a, 5b, and slab catches t6a, 6b are all prepared for two lines, and the two yarns Y, Y2 spun from the spinning units 1a, 1b are independently spun without being combined. is designed to be processed or detected. Although only one winding device 7 is provided for the two yarns Y and Y2, two traverse guides 8a operate synchronously. Has 8b. Next, a winding method of the present invention using the above-mentioned spinning III device will be explained. Two binding yarns Y spun from spinning units 1a and 1b
, Y2 are picked up as they are by the delivery roller 4 and sent to the winding device 7. Then, move the thread Y1 to the traverse guide 8a.
The yarn Y2 is traversed by the traverse guide 8b. Traverse guide 8
If the traverse ranges of the traverse guide 8b and the traverse guide 8b are set so as not to overlap with each other, the threads Y and Y2 are wound up at different positions on the single bobbin 9, and the thread Y
A package P consisting of the yarn Y2 and a package P2 consisting of the yarn Y2 are formed. During this time, yarn breakage is detected by the yarn breakage sensors 3a and 3b, and slabs are detected by the slab catches 176a and 6b, respectively. If an abnormality is detected in either yarn Y or Y2, the cutter in the spinning section 2 is activated to remove yarn Y.
, Y2 are cut and spliced. Splicing two yarns at the same time is easier than splicing two-ply spun yarns because the ends of the package-side yarns are not also combined and there is no need to separate the yarn ends. Thereby, a pair of cheeses P consisting of packages P and P2 having the same winding yarn length can be formed on the bobbin 9. When using the resulting binding thread of a pair of cheeses P as thread for a shuttleless loom without doubling, the winding start part of the thread of one package and the thread of the other package on the common bobbin 9 should be used. It is a good idea to tie the end of the roll. If you unpack the former package in this way, the latter package will also be unrolled, allowing you to use the two packages as if they were one package. Effects of the K Invention: Two single yarns spun by a pair of spinning sections in a two-ply binding spinning machine are guided to a winding device without doubling, and a pair of yarns are placed on a winding bobbin held by a single cradle. According to the method of the present invention for rolling up yarn as cheese, the resulting binding package can be used as it is for yarn feeding in two upper and lower stages of a double twister. In addition, when using the binding system as A yarn for a shuttleless loom, tie the starting part of the thread of one package to the ending part of the thread of the other package, and then unwind from the former's pan cage. Subsequently, the latter package is also unpacked, and the two packages can be used as if they were one package. By winding two pancages onto a single bobbin, the winding width of one package becomes narrower, but a package with a narrow winding width has better unwinding properties at high speed, so it is a suitable package for applications where unwinding performance is important. Become. Furthermore, if a two-part type winding bobbin is used, if the winding bobbin is divided after being wound up as a pair of packages, it can be handled in exactly the same way as if one package was wound up on one bobbin. I can do it. For the above reasons, the winding method of the present invention has the advantage of being able to provide a package that is easier to use than the conventional one in most applications of binding yarn.
