Definitions

  • the present invention relates to a method for spinning a thread on a spinning machine, a corresponding spinning machine with a plurality of juxtaposed spinning stations, each having a drafting with a pair of output rollers and a drafting following, a stretched fiber bundle compacting compression zone containing a circulating air-permeable conveyor belt , which is guided on a provided with a suction slot and arranged on a suction tube sliding surface and which transports the fiber structure over a compression zone delimiting nip to a separation point and an insert for placement on a suction pipe of a spinning station in such a spinning machine.
  • the object is achieved with a method, an insert for a spinning machine and a corresponding spinning machine according to the independent claims.
  • the invention relates, inter alia, to an insert according to the invention, which is intended to be arranged on a suction tube of a spinning station.
  • the corresponding spinning station has in each case a drafting system with a pair of output rollers and a drafting the following, a stretched fiber bundle compacting compression zone, which contains a circulating, air-permeable conveyor belt.
  • the conveyor belt is guided on a provided with a suction slot and arranged on the suction tube sliding surface and over the insert.
  • the conveyor belt transports the fiber structure over a clamping zone delimiting the compression zone up to a separation point.
  • the insert is provided according to the invention at the separation point.
  • the insert is designed such that it determines the separation point and there is a distance of the separation point of the nip, which is predetermined by the spinning material to be spun and or to be spun yarn number.
  • the insert according to the invention becomes a spin agent of the spinning machine.
  • a specific use is used, which determines the distance between the nip and the separation point for the fiber structure. It can be achieved with the use of different curvatures or shapes, which cause a more or less strong support of the fiber structure after the nip or causes a gradual detachment of the fiber structure of the conveyor belt or an abrupt detachment.
  • a corresponding application can be selected.
  • it is particularly possible that thread breaks are reduced. Characterized in that the spinning triangle is made more stable, thread tension peaks are attenuated.
  • Inserts according to the invention are also advantageous because, given a predetermined inclination of the drafting arrangement, which causes a predetermined spacing in a conventional arrangement, they now permit the spacing and thus the wrapping of the fiber structure to be adjusted individually and to achieve the best spinning results. It is only necessary that a suitable insert be used at the spinning station.
  • the distance between the nip and the separation point is between 0 and 30 mm. It has turned out to be particularly advantageous if this distance is between 1 and 5 mm. As already described, the larger distance is here provided for finer yarns, while the smaller distance is sufficient for coarser yarns, since these coarser yarns are more stable and thread tension peaks more easily survive and thus do not lead to yarn breakage.
  • An insert according to the invention is shaped like a ski.
  • the ski-like insert can be arranged on the suction pipe and generate a more or less large distance between the nip and the separation point according to the design of the hill. It is advisable that the lower side of the ski-like insert is substantially flush with the suction tube, while the higher end of the insert extends beyond the contour of the suction tube and deflects the conveyor belt and thereby generates the separation point for the fiber structure.
  • the insert in the area between the nip line and the detachment point has a curvature predetermined by the fiber material to be spun and / or the yarn number to be spun, then, for example, between one nip abruptly acting peel point and a gradually acting peel point or even a release surface.
  • the insert has a length transversely to the fiber transport direction, which corresponds at least to the width of the conveyor belt, a particularly advantageous support of the conveyor belt is achieved.
  • the insert thus forms part of the bearing surface of the conveyor belt. It may be sufficient that the insert is so wide that it supports only one conveyor belt and thus is assigned to only one spinning station. Each of the spinning stations thus has its own use.
  • the insert has a length transverse to the fiber transport direction, which corresponds to the spacing of several spinning stations, then the insert can be installed, for example, for an entire section with several spinning stations and thus serves to support a plurality of conveyor belts.
  • the insert consists of a wear-resistant material, in particular of ceramic or of a wear-resistant plastic
  • the insert can also serve as a reinforcing insert in addition to its function of generating a detachment point. It extends in particular from the nip line to the separation point. A wear of the insert, which is caused by the pressure of the pinch roller on the fiber structure, the conveyor belt and the insert or the suction tube is thereby largely excluded or requires an exchange of the insert only after a relatively long period of time.
  • the insert is not only an element for generating a separation point for the fiber structure, but also a deflection element of the conveyor belt. This causes the conveyor belt is deflected more or less abruptly and thus the separation point and the strength the looping of the conveyor belt influenced by the fiber structure.
  • the insert has a clamping device for replacement on the suction pipe, replacement of the insert is very easily possible.
  • another type of attachment of the insert may be provided on the suction pipe. So this example can also be screwed, glued or otherwise secured.
  • a structure which is provided on the surface of the insert, which is intended for contacting with the conveyor belt, can significantly facilitate the sliding of the conveyor belt on the insert.
  • a spinning machine has a plurality of juxtaposed spinning stations, each with a drafting system with a pair of output rollers and a drafting the following, a stretched fiber bundle compacting compression zone.
  • the compression zone includes a circulating, air-permeable conveyor belt, which is guided on a provided with a suction slot and arranged on a suction pipe sliding surface.
  • the conveyor belt guides the fiber structure over a clamping point delimiting the compression zone up to a separation point.
  • the shape of the sliding surface in the region of the detachment point is designed such that there is a distance of the detachment point from the nip, which is predetermined by the fiber material to be spun and / or the yarn number to be spun.
  • the shape of the sliding surface after the nip until the separation point is crucial for a certain support of the fiber structure to avoid thread breaks in the delicate spinning triangle, which could arise, for example, by thread tension peaks.
  • the spinning triangle is thereby supported on the sliding surface to the separation point, which ensures that with a suitable design and length even thin yarns can endure stress peaks, which do not lead to a yarn breakage.
  • the distance between the nip line and the separation point is about 0-30 mm, preferably between 1 and 5 mm. Depending on the yarn number and fiber material, this distance may vary. It tends to be that finer yarns require a greater distance than coarser yarns. A distance between 1 and 5 mm will be most suitable for most commonly spun fiber materials and yarn counts.
  • the location of the separation point and / or the shape of the surface for the transport of the fiber structure between the nip line and the separation point is selected by the fiber material to be spun or the yarn number to be spun.
  • the location of the detachment point or the shape of the transport surface can be made that the thread breaks are significantly lower.
  • the transport or sliding surface may be formed by an insert disposed on the suction tube, which defines the separation point and / or the shape of the sliding surface.
  • the insert is designed such that it is arranged on the suction pipe per spinning station or along several adjacent spinning stations.
  • the insert is designed to be correspondingly long, so that it affects only one or more spinning stations with respect to the separation point.
  • the insert is interchangeable arranged on the suction pipe. As a result, it is easily possible to use different inserts, depending on the requirements with respect to the fiber material to be spun and / or the yarn number to be spun.
  • suction tube and / or the insert in the region of the detachment point are formed in a curved shape, then an abrupt detachment of the fiber structure from the conveyor belt can be achieved.
  • the suction tube and / or the insert in the region between the nip and the detachment points have a predetermined curvature through the yarn number to be spun and / or the fiber material to be spun, the type of deflection of the conveyor belt and thus the separation point can be determined by this curvature or radius as well as the support surface for the fiber structure can be favorably influenced.
  • FIG. 1 is a part of a drafting 1 with a Doppelriemchen 2 and a pair of output rollers 3 shown.
  • a compression zone 4 is arranged following the drafting 1 .
  • the compression zone 4 has a pinch roller 5 and a suction pipe 6 and a conveyor belt 7 moving over the suction pipe 6.
  • the conveyor belt 7 is driven in the embodiment shown here with a roller of the output roller pair 3 or by the pinch roller 5.
  • a fiber structure 8 is moved.
  • the fiber structure 8 is stretched in the drafting system 1 and then passes into the compression zone 4, in which it is sucked by means of a suction slot, not shown, in the suction pipe 6 on the conveyor belt 7 and compacted.
  • the fiber structure 8 is clamped at a nip K between the pinch roller 5 and the suction tube 6 and is then along a distance L. still on the conveyor belt 7 and the suction tube 6, before it reaches a detachment point A free to the downstream spinning unit with ring and spindle.
  • the length of the spin triangle between the nip line and the fiber binding point in the yarn depends inter alia on the length of the distance L.
  • another length of the spider triangle is optimal. According to the invention it is therefore proposed that the distance, unlike in the prior art is not adjusted by a complex setting, for example, the position of the drafting system to the ring center and inevitably represents a compromise, but that this distance L is variable with little effort.
  • the separation point is the point at which the fiber structure lifts off from the conveyor belt.
  • FIG. 2 is a variant, which is not part of the present invention shown.
  • the suction pipe 6, which is arranged after the pair of output rollers 3 of the drafting system 1 and forms the bearing surface for the conveyor belt 7 and the fiber dressing 8 sucked on it, is replaced.
  • the suction pipe 6.1 which is shown by a solid line, forms due to a small radius R1 only a small distance L1 between the nip K and Ablinateddling A1.
  • This distance L1 is to be increased significantly to a distance L2.
  • the suction tube 6.2 here has a large radius R2, on which the fiber structure 8 is applied.
  • the detachment point A2 is significantly further away from the nip line K and leads the fiber structure 8 accordingly longer.
  • the complete suction tube 6 can be replaced. But it is of course also possible that over a central suction pipe, a corresponding sleeve is inserted, which guides the conveyor belt 7 and has a correspondingly shaped radius. By replacing only this sleeve and not the entire suction tube 6 is thus to easily achieve an adjustment of the distance L. ever greater the adherent length of the fiber composite 8 on the conveyor belt 7, the more the fiber structure is supported in the spinning triangle and can endure yarn tension peaks.
  • FIG. 3 Two further embodiments of the present invention are shown.
  • an insert 10 is arranged in the suction tube 6.3.
  • the insert 10 has a relatively short distance L3 between the nip K and the detachment point A3. If a greater distance A is required for a specific yarn count or a specific fiber material, then the insert 10 can be exchanged for an insert 10. Through the use of 10.1, the distance A4 is achieved, which is greater than the distance A3.
  • the suction tube 6.3 does not have to be replaced for this purpose. It is sufficient if the insert 10 is replaced with the insert 10.1.
  • the insert 10 or 10.1 can either be assigned only to the individual spinning station and have a corresponding width such that the conveyor belt 7 is guided over this one insert 10 or 10.1.
  • the insert 10 or 10.1 can also be designed such that it extends over several spinning positions. For this he can, for example, be inserted or clipped into a guide groove of the suction tube 6.3 and extend over the entire length or even a part of the length of the suction tube 6.3 and thus simultaneously change the distance A for several spinning stations.
  • suction tube 6.3 which receives an existing example of plastic part as insert 10 and 10.1, which has a contour with which one determines the loop length of the fiber strand 8 and the radius of the friction conditions in the spinning triangle are additionally affected can.
  • This additional part has the function of a spinning component and depending on spinning conditions, you can use a part with different contour and deflection radius. On this part or use the conveyor belt 7 is moved. In addition to spinning technological functions, this part can therefore take tribological tasks and optionally also serve as a wear part, if it, as shown, even in the terminal point K below the top roller 5 and the conveyor belt 7 also extends.
  • FIG. 4a With respect to the suction pipe 6.3, another insert 10.2 is provided.
  • the insert 10.2 is as in FIG. 4b shown, only one pinch roller 5 or spinning station assigned.
  • the lateral guide cheeks 11 ensure that the conveyor belt 7 does not leave its position in the axial direction of the suction tube 6.3 and thus can reliably transport the fiber structure 8 via the suction tube 6.3 and the insert 10.2.
  • the insert 10.2 is clamped in the suction tube 6.3 and thus easy to change.
  • FIG. 5 is a further, particularly advantageous embodiment of the present invention shown.
  • an insert 10.3 is inserted in a groove of the suction pipe 6.4.
  • the insert 10.3 is reliably held by the dovetail shape of the groove of the suction pipe 6.4.
  • the conveyor belt 7 in turn extends around the suction tube 6.4 and over the insert 10.3.
  • the insert 10.3 is configured as a ski, so that the conveyor belt 7 abruptly loses contact with the fiber structure 8.
  • the distance L between nip K and separation point A can thereby be kept very short. In particular, the location of the detachment point A can be defined very precisely.
  • the height of the jump is depending on the shape of the suction pipe 6.4 between 0.5 and 5 mm. It is important that the fiber structure 8 lifts sufficiently from the suction tube 6.4.
  • the illustrated inserts 10, 10.1, 10.2 and 10.3 and the following inserts 10.4 and 10.5 may preferably be made of a wear-resistant material, in particular of ceramic or wear-resistant plastic. As a result, the suction pipe 6 is protected from wear. Once the insert is worn, this can be easily and inexpensively replaced. The much more expensive component intake manifold can be used much longer in this way, since it is then subject to almost no wear.
  • FIG. 6a is a plan view of an insert 10.4, which is similar to the use of 10.3 of FIG. 5 is presented, layed out.
  • the insert 10.4 has a length which corresponds approximately to the width of the conveyor belt 7.
  • Klippse 12 are provided, which can be clamped in a groove of the suction pipe 6.4 and thus secure the insert 10.4 on the suction pipe 6.4.
  • an opening 13 is provided.
  • the opening 13 may be closed, for example, and be opened only to remove the insert 10.4. But it is also possible that the opening 13 is always open and thus accessible for a tool to remove the insert 10.4 from the groove of the suction pipe 6.4.
  • FIG. 6b is a side view of the insert 10.4 shown. From this representation, the ski-shaped cross-section of the insert 10.4 can be seen. The left side of the insert 10.4 shown here is largely flush with the contour of the suction tube 6.4, while the right side of the insert 10.4 protrudes beyond the contour of the suction tube 6.4 and thus causes the conveyor belt 7 like a tree. At the high edge of the insert 10.4, the separation point P will result for the fiber structure 8. Furthermore, in FIG. 6b to recognize the Klippse 12, which are designed to be elastic, to allow attachment in the groove of the suction pipe 6.4.
  • FIG. 7a is a further embodiment of an insert 10.5 shown.
  • the insert 10.5 has a slightly different ramp shape, which projects beyond the groove of the suction tube 6.4 addition. This can be seen in the side view of FIG. 7b. While the use 10.5 in its lower area essentially the use 10.4 of the FIG. 6B corresponds, the upper contour is guided flat and extends beyond the width of the groove or receptacle for the use 10.4 and 10.5 in the suction pipe 6.4 addition.
  • This overhang of the insert 10.5 ensures that the separation point P is further away from the nip K and thus a greater distance L is generated.
  • the height h of the overhang is preferably between 0.5 and 5 mm, depending on the construction of the suction tube.
  • FIG. 7a the surface of the insert 10.4, through which the fiber composite and the conveyor belt 7 is guided, structured.
  • this structure (14) the friction of the conveyor belt 7 can be reduced on the insert 10.5 and the sliding of the conveyor belt 7 can be facilitated on the insert 10.5.
  • structure (14) for example, as shown here, a number of spherical or other depressions or slight elevations may be provided.
  • the depression or elevation for example, have a depth or height of 0.1 to 0.5 mm.
  • the present invention is not limited to the illustrated embodiments. So it is not necessary that the use of the terminal point k extends to the separation point A. It is also quite possible that it is arranged only in the region of the detachment point A and there causes the separation of the fiber composite 8 from the conveyor belt 7. Further modifications are possible within the scope of the claims at any time.
