Abstract

PURPOSE:To realize separation of accompanying fluid and vortex from a traveling linear body by providing in the traveling direction of a linear body at intervals, the plural number of separation plates equipped with a linear body traveling passage formed by taper-like through holes enlarged round the center of the linear body. CONSTITUTION:When a linear body 4, accompanied by gas, is put in its traveling motion through a through hole 5 of a separation plate 1, the gas is expanded along the taper-like through hole 5. At an entrance of the through hole of the next separation plate, the gas expanded beyond the diameter of the entrance of the hole is drawn out from a gap formed between the plates, in the direction orthogonal to the traveling direction. In case of a linear body including liquid, the liquid is drawn out along with the gas. Since excessive gas can be separated from the liner body 4 in both cases, the subsequent process for said body 4 can be conducted easily.

【発明の詳細な説明】 本発明は走行線状体の随伴流を走行線状体から分離する
装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for separating the accompanying flow of a traveling linear body from the traveling linear body.

線状体を流体中で走行させると随伴流や渦が発生するが
、該線状体の走行速度の高速化を行なうと該随伴流及び
渦は速度の増加と共に急増する。When a linear body is run in a fluid, accompanying flows and vortices are generated, but when the running speed of the linear body is increased, the accompanying flows and vortices rapidly increase as the speed increases.

定紡糸ができなくなる。Furthermore, in a yarn spinning factory, for example, a fluid is forcibly applied from the outside, and when the linear body is drawn or transported by the fluid, the amount of fluid that is brought along with it increases as the traveling speed increases. It is necessary to increase it accordingly. It is preferable that such an accompanying flow of the traveling linear body exists in subsequent steps, and it is necessary to ultimately separate it from the linear body. For example, in the wet spinning manufacturing process, when a yarn containing liquid is sucked by an air sucker, a large amount of liquid forms a mist at the yarn outlet of the air sucker, which complicates post-processing of the mist. Furthermore, increasing the running speed in order to increase the production rate of yarn causes the generation of vortices and an increase in accompanying flow, which increases yarn tension and causes a decrease in yarn properties. Further, the thread body containing the liquid is disturbed by the inertial force of the liquid at the direction changing guide portion, and fluff and yarn breakage occur. In the melt-spinning manufacturing process, the fluid collides with the oiling section and the winding section, causing spots of oil adhesion and thread drop at the end of the cage, as well as increasing the running speed as in the wet-spinning manufacturing process. The vortex increases and the running yarn becomes unstable, making stable spinning impossible.

本発明は上記の如く、走行線状体から随伴流体及び渦流
を分離する装置を提供することを目的としている。As described above, it is an object of the present invention to provide a device for separating an accompanying fluid and a vortex from a traveling linear body.

発明の実施の態様を詳述する。That is, the device of the present invention that achieves the above object is provided with a linear body running path consisting of a substantially square-shaped through hole that is enlarged around the linear body in the running direction of the linear body. The present invention is characterized in that a plurality of separation plates are provided at intervals, and the space formed between each separation plate constitutes a fluid discharge path to separate the accompanying fluid and vortex from the traveling linear body. Embodiments of the present invention will be described in detail below with reference to the drawings.

角方向へ、該板間で構成される間隔より抜き出される。FIG. 1 shows an example of the implementation of the present invention, in which a separation plate 1 having through holes 5 of 1,50 mm in diameter over the entire length of the plate is attached to a support 2 with a pin 3 at intervals. . When the linear body 4 carrying gas is passed through the through-hole 5 of the separation plate l through the device configured in this way and allowed to run, the gas expands along the chimney-shaped through-hole that expands in the direction of travel, and moves to the next separation plate. At the inlet of the through hole 1, the gas expanded by a diameter larger than the inlet diameter of the hole is extracted from the gap formed between the plates in a direction perpendicular to the running direction.

ろる分離板ＩＡを用いて実施しても同様の効果がある。In addition, in the case of a linear body containing liquid, the liquid will escape together with the gas. Therefore, in both cases, excess fluid can be separated from the linear body 4, making it easier to process the linear body in subsequent steps. In this device, the same effect can be obtained even if a separation plate IA having a part of the through hole 5A is tapered as shown in FIG. 2 is used.

。Furthermore, similar effects can be obtained when the separation plate 1 and the separation plate IA are used in combination. Further, as shown in FIG. 3, the same effect can be obtained when the plate is provided with a slit 6 through which a linear body can pass parallel to the running path. Furthermore, the effect will be improved if a cap is provided in the fluid discharge path of the present device and drawn by a vacuum system.

な物が得られる。To give an example of a specific effect of using this device, for example, in a wet spinning manufacturing process, if this device is installed immediately after the spinning bath, excess accompanying spinning solution can be separated, making it easier to process in the subsequent process, and The spinning solution recovery efficiency increases. In melt spinning, since this device is installed after the solidification point,
Excess entrained air and eddies can be separated, oiling etc. can be easily treated, tension can be lowered, and fibers with good physical properties can be obtained.
