INSTRUCTIONS OF THE INVENTION: TECHNICAL FIELD The present invention relates to a yarn pull-out nozzle for an open-end rotor spinning device having a funnel-shaped yarn turning region and a hollow cylindrical nozzle throat connected to the region. And ribbed ridges, the rib ridges are arranged in the yarn turning region, and the Hans is in the form of a spiral of a plurality of spirals which are steeper and extend toward the nozzle throat in the axial direction of the yarn pulling nozzle Go to the area of the nozzle throat. • [Prior Art] Openings such as yarn pull-off nozzles for rotor spinning machines have a great influence on the quality of the spun yarn and the stability of the spinning operation (ie the number of yarn breaks). Here, the facts show that the above two requirements, that is, the yarn quality and the yarn operation are stable, and the use of the same yarn to pull the nozzle is often not satisfied at the same time. To achieve good yarn quality, the facts show that the yarn is pulled away from the yarn in the direction of the yarn to smooth the leaves or has a so-called "spiral stuctur" (Spiralstuktur) for this purpose. However, the spinning stability of this "spiral structure" is generally too low. Therefore, in order to improve the spinning stability, some yarn pull-out nozzles have been developed, and the yarn turning area is provided with a notch or the like, so that the yarn is produced. In the middle of the production. "Fake inspection of the month", this kind of false inspection is necessary for spinning stability. But these gaps often have a negative impact on yarn quality. German Patent No. DE 37 07 526 A1 discloses a yarn of the above kind that is inferior to the mouth. Its yarn has a ribbed bulge in the turning region, and is in the form of a spiral of spirals m which extends into the nozzle throat (Dusen schlund, English: 6 1329145 n〇zz]e throat) in the area of the bu and ~ in the yarn pulled away from the nozzle of the shaft part #中中-the more steeper, the action circle + upper / 丄 steeper ... the surrounding direction is still obvious vector itself The yarn pull-off nozzles, which are constructed in four ways, are beneficial to the fried shell, but the spinning stability is insufficient. This is not the case with the yarn pull-off nozzle of M 39 34 166 C2, in which the noisy turning zone and the nozzle throat are arranged on separate components which are separated from each other by the joint seam. The nozzle throat has a convex-convex configuration, and the yarn is turned to the £ domain S to avoid a knife-shaped notch. This method of inserting and pulling the nozzle is satisfactory in terms of spinning stability, and it is a good time to make a 'yno' and a 'yno quality, and it does not meet all the requirements, because it is too harmful to the yarn. . SUMMARY OF THE INVENTION An object of the present invention is to provide a yarn pull-out nozzle which can balance the requirements of yarn quality and spinning stability as much as possible. The purpose of the k kinds of purposes is to set the yarn turning area and the nozzle throat on the nozzle member, and the nozzle member can be separated from each other on the "separating seam" (W). The rib type ridge is on the separating seam. The vehicle substantially parallel to the yarn pulled away from the nozzle (7) extends from the bottom and has a projection in the nozzle throat that cooperates with the rib ridge. The projection is also arranged parallel to the axis of the yarn, but along the peripheral direction and the rib The style is staggered. The multi-strand helical configuration in the turning area of the funnel-shaped yarn produces a force that acts on the yarn and its strength is affected by the rib-like bulge, and the quality of the yarn is improved by the reverse point. On the other hand, placing the ribbed ridges in parallel toward the nozzle throat temporarily creates a false twist in the critical yarn region, which improves the spinning stability. Since there are protrusions in the nozzle throat that cooperate with the rib-shaped ridges 7 1329145 'they are similarly arranged parallel to the axis of the yarn pulled away from the nozzle, but along the circumference: the direction is set to be offset from the rib-shaped ridges, thereby enhancing the visit Stabilized) There is a separate seam between the nozzle members that contain the yarn turning area and the nozzle throat. Therefore, the manufacture of the yarn pull-out nozzle becomes simpler. The nozzle member having the spiral structure including the yarn turning region, and the nozzle throat-containing member having the projection in the nozzle throat can be manufactured by a simple method, and combined into an integral yarn pull-off during operation. nozzle. The ribbed ridges and projections are arranged offset from each other along the circumference of the circumference, and the outer direction of the a ω 丨° is advantageous to avoid any error in the area of the separation seam. Since it is practically impossible to connect the protruding portion to the ribbed ridge in a "seamless gap", it is preferable to be able to be staggered in the circumferential direction. Thus, the action of the yarn pulling the nozzle does not occur. Affected. It is advantageous (although not necessarily) to have the number of rib-like ridges and projections in the region separating the seams. In addition, if the projection is wider than the ribbed ridge, it is not harmful. The projections in the nozzle throat can be set such that they are seen in the cross section of the nozzle throat - leaving a cross-shaped through passage therebetween. In order to have a long service life, it is advantageous if the two nozzle members, that is to say the nozzle member containing the ribbed ridged yarn turning region and the nozzle member containing the nozzle throat and the projection, are made of ceramic :3 Other advantages and features of the present invention are found in the following description of an embodiment (high magnification scale). [Embodiment] The open end rotor spinning device, which is only partially illustrated in Fig. 1, contains an 81 1329145 spinning rotor (1). The spinning rotor (1) consists of a rotor disk (7) and a dry shaft (3) in the rotor disk. The dry shaft (3) is supported and/or driven in a circular manner. In operation, the rotor disk (3) rotates in a low pressure chamber (4) formed by a rotor housing (5) that is connected to the body by a circle (not shown) Vacuum source (suction direction A). The rotor disk (7) has a fiber guiding surface (7) which tapers to a fiber collecting groove (6). In the fiber guiding groove (6), the rotor disk (2) The diameter of the hollow inner casting space of the largest spinning rotor (1) can be pulled out through the rotor housing (5)_ front opening (8) to the operating side of the open end spinning device. In operation, the sub-housing (5) The opening (8) is closed with the open front side (9) of the rotor disk (2) by a removable cover member (1G). The cover member (1G) is operated against the rotor housing (5). There is an annular seal (11) in between. The cover member (10) comprises a fiber supply passage (12) which is located outside the drawing and which starts on a cotton roller in a manner not shown, and which opens π ( 13) toward the direction of the fiber guiding surface (7). With the action of the vacuum source described above, the fibers separated by the open cotton roller during operation are passed through the fiber supply passage. To the fiber guiding surface, from which it slides into the fiber collecting groove (6), where a fiber loop is formed, and in the form of a yarn (14) (indicated by a broken line) in a conventional manner The direction of the shaft (3) (Schaft) is pulled out. This transporting empty milk [which is sucked through the fiber supply passage (12)] can pass through an overflow slit (15) on the open side (9) of the spinning rotor. The spun yarn (14) is first from the fiber collecting groove in a normal plane of the spinning rotor (1) [at least in the normal plane, the normal plane is perpendicular to the dry axis (3)] Feeding, then pulling through a pair of yarns (16) in the pull-off direction B with a pair of 9 1329145 pulling away from the roller (not shown) and pulling it away and sending it to a "running spool" (also not shown) The yarn pull-out passage (16) is located at least in a trapping region that is coaxial with the dry shaft (3) of the spinning rotor (!), so that the yarn leaving the fiber collecting groove (I" first turns to about 90. The yarn (14) is simultaneously cranked in the normal direction of the above-mentioned normal surface. There is a multi-part yarn pulling nozzle (17) (it is also hereinafter) Description) for deflecting the yarn (14) from the normal face into the yarn drawing passage (丨6). The yarn is pulled away from the nozzle (16) by a substantially funnel-shaped yarn turning area ( I" starts at a plane (19) in the normal plane and transitions into a hollow cylindrical nozzle throat that follows. The yarn turning area 〇8) and the nozzle throat (20) are set in special In the ceramic nozzle members (21) and (22), the ceramic member (21) (22) is dried into a nozzle holder (adding 8〇11 such as 81111 吕) (23). The nozzle holder uses a "holding magnet" (24) and (25) are held on the cover (1〇). It is to be noted here that the crank-like running speed of the yarn (14) is much faster than the speed of the yarn (work 4) in the pulling direction B. Since the yarn (14) runs in a crank shape on the surface (19), the yarn (14) is rotated in a balloon shape from the nozzle throat (20), wherein the yarn is pressed by the centrifugal force to the nozzle throat (2〇). On the wall (26). We can take advantage of this shape, in which the wall (26) is designed in a special way. As described above, the yarn is pulled away from the nozzle (17) to satisfy a plurality of partial conflicting requirements, that is, on the one hand, it is ensured that the spun yarn has good quality, and on the other hand, it is less likely to cause yarn breakage. The quality requirements are mainly achieved by the special design of the yarn turning area (18), and the requirements for spinning stability are mainly achieved by the design of the wall (26) of the nozzle throat (20). This will be explained in detail below in conjunction with Figure 2. 10 1329145 Yarn turning area (18) towel with ribbed lowering (27) (28) (29) (30), in the shape of a four-threaded (four-threaded) spiral, the spiral is well rounded . The rib starts at the region of the nozzle edge (3) and extends straight into the region of the deep nozzle throat where it becomes steeper toward the nozzle throat until it reaches the throat of the nozzle substantially parallel to the yarn. The axis of the nozzle (17) is up. The rib-shaped ridges (27) to (30) are designed to have the same width throughout the entire length. The spiral configuration in the yarn turning area (18) is used to provide good yarn quality. In particular, for reasons of manufacture, the multi-part yarn pull-out nozzle (17) is designed in such a way that the yarn turning area (18) and the nozzle throat (2) are provided in the nozzle member (21) (22), the nozzle The members (21) (22) may be separated from each other on a separating seam (32), and the suitable position of the separating seam (32) is preferably the relevant position of the bulge of the yarn turning area, and the nozzle throat (2 〇) The pure cylindrical region starts at this position, and the rib-shaped ridges (27) to (3) fit, and the projections (33) are also arranged parallel to the axis of the yarn pulling the nozzle (17), but the projections (33) The rib-shaped ridges (27) to (30) are arranged to be shifted in the peripheral direction. Since they are mutually misaligned, the error in the transition between the rib-shaped ridges (27) to (30) and the projections (33) need not be considered. In particular, as shown in Fig. 2, a protruding cross section (34) is left between the projections (33) as viewed along the cross section of the nozzle throat (20). Furthermore, it can be seen from Fig. 2 that the projection (33) is advantageously more visible than the ribbed ridges (27) to (30) due to the separation between the two nozzle members (21) (22). The slit (32) is therefore not required to make the number of ribbed ridges (27) to (30) equal to the number of the projections (33). Furthermore, it is not necessary to have the ribbed ridges (27) to (30) absolutely flat 1329145 extending beyond the axis of the nozzle (17). Finally, it is even possible to leave the end of the rib-like ridges (27) to (10) at the beginning of the projection (33).
