L Prior Art 3 Background of the Invention 10 In order to guide the yarn, a yarn guide is installed in the equipment for manufacturing or processing the yarn, such as in a melt spinning device, so that the yarn can maintain a defined guiding route from one processing stage to the next. . This is achieved, in particular, with known thread guides, so-called pigtail-shaped thread guides. Such a guide consists of a helical guide portion forming a guide loop and a substantially flat fixed portion. Such a thread guide is known, for example, from DE 35 20 864 A1. Here, the guide portion and the fixing portion are formed of a circular steel wire member. This is often the desire when guiding multiple running threads. That is, as small a wire pitch as possible is achieved between the wires. However, this causes a problem when a known guide is used: the guide portion has a relatively small radius for guiding the wire in the guide ring to maintain a small guide width. This results in a high unit area load on the yarn guide with a correspondingly high friction, which can lead to local heating and ultimately damage to the yarn. Another disadvantage is that the guiding part itself is weak. 5 200400151 [Abstract] Summary of the invention The object of the present invention is therefore to design such a guidewire so as to form a guidewire ring with a contact surface as large as possible, while the external dimension 5 is also small. The other purpose of Moben U is to provide a kind of support with multiple thread guides. The guide ring on the thread guide has a heart under the large wire connection parts of Lixiong, _ « distance. The above purpose is achieved for the guidewire according to the present invention, that is, the guide 10 ϋΓ points have a kind of asymmetrical shape which is circular on one side of the guide wire loop. The contact side; large asymmetrical shape cross section, the guide part facing away from the guide wire ring-15 20 needs the shape or the shape with the peripheral axis. It just rings. At ==, the scale material is not affected by the material. Second more = Γ ", the circular shape of the guide part should preferably form a sufficiently large contact surface for guiding the thread. Special shape =! Semi-circular or, circular structure, the result proves that the shape of the ’guide part of the bottom of the _ sliver holder to achieve this, g [? A guide wire with multiple guides appears in Yu, that is, the asymmetric shape cross section of the guide wire of the guide wire; two: to 200400151 the distance between two adjacent wire guides is smaller than the circle Four times the radius. In this way, the wire b is guided through the guide holder at a narrow pitch. Therefore, especially when the yarn is guided in the spinning equipment, the friction of the yarn is reduced while maintaining a small distance of preferably less than 15mn. In this process, reducing the silk friction directly played a role in improving the quality of the silk. Advantageous further designs of the invention are given in the scope of other patent applications. BRIEF DESCRIPTION OF THE DRAWINGS An embodiment of a wire guide according to the present invention is shown in FIG. 1 and an embodiment of a wire guide holder according to the present invention is shown in FIG. 2. Embodiment C; j Detailed description of the preferred embodiment In Fig. 1, different views of a yarn guide according to the present invention are shown. Figure U shows a side view of the guide. Fig. H2 is a plan view, and Fig. 13 is a cross-sectional view. The following description applies to all diagrams unless otherwise specified. The guide according to the present invention is composed of a fixed portion 4 and a guide portion 3. The fixed portion 4 and the guide portion 3 are fixedly connected to each other. The fixing portion 4 is made straight, preferably a hollow cylinder. The guide portion 3 spirally forms a 20 guide wire loop 5. Among them, the free end of the guide portion 3 is oriented in the direction of the fixed portion 4.
如第1·3圖所示，導向部分3有/個非對稱的形狀截面 8。該形狀截面8主要是由在導向部分3—側的圓形7和相對 一側的扁平形10組成的。在這個實施例中，圖形7的半徑R 200400151 沒樣選定，使形狀截面8大致具有半圓形的形狀。其中，導 向部分3的具有圓形7的側面就是導絲環5内的接觸面。導向 部分3的具有扁平形10的側面則是向外的。 為了引導絲線，絲線首先穿進成螺旋形的導向部分3， 然後在導絲環5内在圓形7上導引。在第13圖中絲線用附圖 標記9表示。 在一個實施例中，圓形的半徑為3mm。由於導向部分3 的相對一側為扁平形10，故可使導絲器的寬度大約為 10 7mm’其中，導絲環5的直徑大約為imm。在此，導向部分 3可以用陶瓷材料製造。 在第1圖表示的實施例中，固定部分4與導向部分3不 同’具有-圓形的形狀截面。而導絲器這樣設計也是比較 有利的：導向部分3和固定部分4均具有非對稱的形狀截 面。為了有儘可能大的接觸面用於引導絲線，形狀截面為 半橢圓形特別合適。而這裡也有可能將導向部分一側上的 圓形設計成不均-的，例如圓形7由兩個不同的半徑組合在 -起，使導絲環5的絲線進人及絲線離開處具有不同的形 狀。 在第2圖中示意地表示出按照本發明的導絲器支架的 2〇多純圖。第圖表示導絲器支架的俯視圖，第2.2圖表示 導絲器支架的剖視圖。 下面的說明只要沒有特別指明是針對這些圖中的某— 個，就對所有的圖都適用。在這個實施例中，導絲器支宇2 帶有三個並排設置的導絲器UM·2、和⑴每個導絲器 200400151 1 · 1至1.3都與;^據第1圖的前面的導絲器實施例完全相同。 有關内容參照前面的說明。 導絲器1.1至1_3以間隔距離Α設置在導絲器支架2上。 其中，導向部分3的帶有扁平形10的側面互相對置。間隔距 5 離A與導絲器1.1至1.3導向部分3上的圓形7的半徑之間的關 係這樣選擇，即，使間隔距離A小於半徑R的四倍。通過遵 循關係。As shown in Fig. 1-3, the guide portion 3 has an asymmetric shape cross section 8. This shape section 8 is mainly composed of a circle 7 on the side of the guide portion 3 and a flat shape 10 on the opposite side. In this embodiment, the radius R 200400151 of the figure 7 is not selected so that the shape section 8 has a substantially semicircular shape. Among them, the side surface of the guide portion 3 having a circle 7 is the contact surface in the guide wire loop 5. The side of the guide part 3 having the flat shape 10 is outward. In order to guide the thread, the thread is first threaded into a helical guide portion 3 and then guided on a circle 7 inside the guide loop 5. The silk thread is designated by the reference numeral 9 in Fig. 13. In one embodiment, the radius of the circle is 3 mm. Since the opposite side of the guide portion 3 is a flat shape 10, the width of the wire guide can be approximately 10 7 mm ', where the diameter of the wire guide ring 5 is approximately imm. Here, the guide portion 3 may be made of a ceramic material. In the embodiment shown in Fig. 1, the fixing portion 4 is different from the guide portion 3 'in that it has a circular cross section. It is also advantageous to design the thread guide such that the guide portion 3 and the fixed portion 4 each have an asymmetrical shape cross section. In order to have the largest possible contact surface for guiding the thread, a semi-elliptical shape is particularly suitable. Here, it is also possible to design the circle on one side of the guide part to be uneven. For example, the circle 7 is formed by combining two different radii from each other, so that the yarn entering and leaving places of the guide wire ring 5 are different. shape. Fig. 2 is a diagrammatic representation of a 20-pure figure of a guidewire stent according to the present invention. Fig. 1 shows a plan view of the guidewire holder, and Fig. 2.2 shows a cross-sectional view of the guidewire holder. The following description applies to all diagrams as long as they are not specifically indicated for one of these diagrams. In this embodiment, the guide 2 is provided with three guides UM · 2, which are arranged side by side, and each guide 200400151 1 · 1 to 1.3; and according to the previous guide of Fig. 1 The yarn embodiment is exactly the same. For details, refer to the previous description. The thread guides 1.1 to 1_3 are provided on the thread guide holder 2 at an interval A. The side faces of the guide part 3 with the flat shape 10 are opposed to each other. The relationship between the separation distance 5 from A and the radius of the circle 7 on the guide portion 3 of the guide 1.1 to 1.3 is selected so that the separation distance A is less than four times the radius R. By following the relationship.
A<4R 而保證：由導絲器1.1至1.3上的圓形7所形成的引導絲 10 線的接觸面在最小化絲線間距的情況下具有足夠的強度和 抗摩擦能力。這種導絲器支架可以優選應用於十道或十二 道POY(預取向絲)/FDY(全拉伸絲)設備中，以實現小的絲線 間距。從而，就可以使用經濟的不長長地伸出的機組來加 工和處理絲線。此外，導絲器内的絲線摩擦也能減小，從 15 而在熔融紡絲中可得到較好的絲線質量。A < 4R guarantees that the contact surface of the guide wire 10 formed by the circular 7 on the guides 1.1 to 1.3 has sufficient strength and friction resistance while minimizing the wire pitch. Such a wire guide holder can be preferably used in ten or twelve POY (pre-oriented yarn) / FDY (fully drawn yarn) equipment to achieve a small wire pitch. As a result, it is possible to process and process the yarn using an economical, non-extended unit. In addition, the yarn friction in the yarn guide can also be reduced, and a better yarn quality can be obtained in melt spinning.
