Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention is a block that produces a blended yarn with different fiber materials arranged in the center and outer layers. The present invention relates to an apparatus for producing a lent yarn.

0002

[Conventional technology]

In the spinning process, a blended yarn (two yarns) with different fiber materials in the center and outer layer is used. This blended yarn has fabric quality features The purpose is to utilize the significance of each fiber material based on the following. For example, cotton fibers on the outside. Fabrics woven from yarns with polyester fibers inside are one of the advantages of cotton. It has the feel of 100% cotton, which is a natural fiber, and absorbs moisture with less pilling. In addition to having properties such as good elasticity, polyester also has the advantage of shrinkage after washing. It has features such as low fabric strength, high fabric strength, and good wash and wear properties.

0003 The blend yarn manufacturing equipment includes back rollers, aprons, and front rollers. A device mainly composed of rollers is known (Japanese Unexamined Patent Publication No. 63-75124), and this manufacturing equipment The purpose of this process is to arrange the supplied sliver into a fiber bundle of a predetermined thickness.

0004

[Problem that the idea aims to solve]

By the way, the above-mentioned blend yarn manufacturing device has a back roller on the fiber bundle input side. An inverted T-shaped trumpet guide is installed to separate different types of slivers into upper and lower parts. The slivers were guided individually depending on the thickness of the yarn to be spun. Since the thickness of the sheath is different, the width of the sliver of the outer layer material (sliver for the sheath) will change. Sometimes, the core material sliver (core sliver) is placed in the center of the sheath sliver. It is difficult to lead them to the club.

[0005] For this purpose, the sheath sliver is guided to the back roller, and from this back roller The core is attached to the center of the expanded sheath sliver by a long and thin cylindrical core guide. However, the core guide is an elongated circle. Since it is formed into a cylindrical shape, it is difficult to pass the core sliver through the core guide.

[0006] Therefore, this invention was made taking these circumstances into consideration, and its purpose is a blended yarn that allows the core sliver to be easily threaded through the core guide. Our goal is to provide manufacturing equipment for

[0007]

[Means to solve the problem]

In order to achieve the above purpose, the blend yarn manufacturing device of the present invention is equipped with a draft A core sliver is placed in the center of the sheath sliver that has passed through the back roller of the device. If a core guide is provided inside and this core guide is formed into a gutter shape with an open upper part, In both cases, the outlet portion thereof is formed into a cylindrical shape.

[0008]

[Effect]

Since the upper part of the core guide is open, the core sliver can be passed through the cylindrical outlet. This makes it easier to pass the core sliver through the core guide. In addition, the outlet of the core guide is formed into a cylindrical shape, which prevents the sliver from coming off. It will be.

【Example】

Embodiments of the present invention will be described below with reference to the accompanying drawings.

0010 In FIG. 1, 1 indicates a draft device of a spinning machine, and this draft device 1 is a 4 consisting of a rear roller 2, a third roller 3, an apron 4 and a front roller 5. Although it is a wire type, it may be a three-wire type or other type, and a predetermined ratio derived from this, for example, 70% of the sliver for the outer layer material (sliver for sheath) Sb and 30% of the sliver for the core material The rotational speed of the sliver consisting of bar (sliver for core) Sa is set to increase in stages. Remove the back roller 2, third roller 3, apron 4 and front roller 5 in this order. During the next pass, it is arranged into a fiber bundle of a predetermined thickness.

[0011] Behind (upstream) of the back roller 2 is a roller for guiding the sheath sliver Sb. A cylindrical trumpet guide 6 is provided as a sheath guide. The guide 6 moves even if the position of the sliver Sb coming out from it is thin. The diameter of the outlet is reduced to prevent

0012 Furthermore, there is a space between the back roller 2 and the third roller 3 as shown in FIGS. 1 and 2. A core guide 7 for guiding the core sliver Sa is provided. core The guide 7 has an outlet 7b that is connected to the spread sheath sliver S from the back roller 2. The sliver Sb runs from the center of the trumpet guide 6, that is, from the center of the exit of the trumpet guide 6. on a line extending in the row direction, substantially perpendicular to the running direction of the sliver Sb, and a third roller It is placed close to 3. This core guide 7 has an open upper part 7a. The outlet portion 7c of the sheath sliver Sb is shaped like a trough. It has a triangular cylindrical shape that becomes convex toward the downstream side in the row direction, and as it goes toward the outlet 7b. The core sliver Sa is reduced in shape so that it can be squeezed into a thin shape. Squeezing into the valley on the downstream side in the running direction of the triangular sliver Sb at the outlet 7b of the guide 7 The sheath sliver Sb is guided to the center of the sheath sliver Sb. Furthermore, the core The outlet portion of the guide may be formed in any cylindrical shape, preferably cylindrical. It is preferable to form a wedge shape that is convex toward the downstream side in the running direction of the base sliver Sb. .

[0013] Now, the sheath sliver Sb is passed through the trumpet guide 6 to the back roller. 2 and extending in a substantially equal width on both sides of a line extending in the running direction of the sliver Sb, A core sliver Sa is guided from a core guide 7 to this central portion.

[0014] The core guide 7 has a gutter shape with an open upper part 7a, and only the outlet part 7c is cylindrical. Because of this, in order to pass the core sliver Sa through the core guide 7, it must be opened. It is only necessary to pass the sliver Sa through the cylindrical outlet part 7c from the upper part 7a, and Since the portion 7c is narrowed toward the outlet 7b, the core sliver Sa can be passed through easily. Further, the outlet portion 7c of the core guide 7 is formed in a cylindrical shape. Therefore, the sliver Sa is prevented from coming off. In addition, the core guide 7, the outlet 7b is formed in a triangular shape convex toward the downstream side in the running direction. Therefore, the sliver Sa pulled in the running direction is squeezed into the triangular valley and exits. Since it comes out from 7b, even if the thickness of the sliver Sa changes, the sliver Sa is always It becomes the minimum state and is derived from the same position. Therefore, the core sliver Sa is It will be reliably guided to the center of the sheath sliver Sb. Furthermore, that Since the outlet 7b of the core sliver is disposed close to the third roller 3, the core sliver Sa is sandwiched between the third rollers 3 in a thin state with almost no expansion.

[0015] Then, the slivers Sa and Sb are sequentially passed through the apron 4 and the front roller 5. The fibers are twisted into fiber bundles of a predetermined thickness, then twisted and packaged ( (not shown) etc.

[0016]

[Effect of the idea]

In summary, according to the present invention, the core guide for guiding the core sliver is Since it is formed in the shape of an open gutter and the outlet part is formed in a cylindrical shape, it is easy to use for the core. It has the excellent effect of allowing the driver to pass through the core guide easily.
