Definitions
- the present invention relates to a spinning station of an air spinning machine, which serves to produce a yarn from a fibrous fiber structure consisting of fiber, wherein the spinning station a vortex chamber with an inlet opening for the operating during the air spinning machine in a transport direction in the vortex chamber incoming fiber structure and at least partially in comprising the vortex chamber extending Garnticianselement, wherein the spinning station has directed into the vortex chamber air nozzles which open in the region of a vortex chamber surrounding the wall in the vortex chamber and the air in a predetermined direction of rotation in the vortex chamber can be introduced to the fiber structure in the region of an inlet mouth of Yarning element to impart a rotation in said direction of rotation, wherein the Garn Strukturselement has a discharge channel through which the yarn from the vortex chamber is removable, wherein in the region of the inlet opening of the vortex chamber a Guidance arrangement for guiding the fiber composite is arranged, and wherein the guide arrangement comprises at least two guide sections spaced apart from each other, whose mutual
- Air-jet spinning machines with correspondingly equipped spinning stations are known in the prior art (see, for example, EP 0 990 719 B1, DE 40 36 119 C2) and serve to produce a yarn from an elongated fiber structure.
- the outer fibers of the fiber composite are wound around the inner core fibers by means of a vortex air flow generated by the air nozzles within the vortex chamber in the area of the aforementioned inlet mouth of the yarn formation element and finally form the binder fibers which determine the desired strength of the yarn.
- This creates a yarn with a true rotation, which finally dissipated via the discharge channel from the vortex chamber and z. B. can be wound on a spool.
- the term yarn is generally understood to mean a fiber structure in which at least a part of the fibers around an inner core is formed. sores are.
- a yarn is included in the traditional sense, which can be processed into a fabric, for example with the aid of a weaving machine.
- the invention relates to air spinning machines, with the help of so-called roving (other name: Lunte) can be produced.
- roving other name: Lunte
- This type of yarn is characterized by the fact that, despite a certain strength, which is sufficient to transport the yarn to a subsequent textile machine, it is still delayable.
- the roving can thus with the help of a defaulting device, z.
- a roving processing textile machine such as a ring spinning machine, are warped before it is finally spun.
- the rotation generated in the region of the yarn formation element does not extend beyond the inlet opening in the direction of transport of the yarn or of the fiber structure. In other words, it should therefore be ensured that the fibers of the fiber dressing retain their original orientation prior to contact with the vortex air flow and only receive the corresponding rotation within the vortex chamber. If the rotation were to propagate counter to the transport direction, the associated reverse rotation of the fiber composite would inevitably lead to a reduction of the desired binder fibers or to a reduced distortion of the fiber composite in the region of a distortion device arranged upstream of the vortex chamber.
- the object of the present invention is therefore to propose a spinning station of an air-jet spinning machine which effectively counteracts a re-planting of the rotation of the fiber composite in the area of the vortex chamber against the transport direction thereof, without causing an excessive reduction in the number of binding fibers.
- the object is achieved by a spinning station with the features of patent claim 1.
- the spinning station is characterized in that, in addition to the guide sections acting on the fiber structure from the outside, the guide arrangement comprises at least one middle guide element which extends at least partially between the guide sections in a section running perpendicular to the longitudinal axis of the trigger channel /
- the middle guide element is thus located in an area that has to be passed by the fiber bundle entering through the inlet opening of the vortex chamber. This leads to a direct contact between the fiber structure and the middle guide element, which finally a lateral, d. H. directed perpendicular to a longitudinal axis of the discharge channel, deflecting the fibers of the fiber composite causes.
- the middle guide member ensures that a portion of the fibers of the fiber composite are forced outwards and thus particularly effectively detected by the air vortex flow generated by the air nozzles and the middle, untwisted Fiber band core can be looped.
- the guide assembly thus consists of a central guide element, which is located in the transport path of the fiber composite, and a plurality of guide sections, which in turn should also be placed in the region of the inlet opening of the vortex chamber and contact the passing fiber structure mainly from the outside.
- the central guide element extends at least in sections on the longitudinal axis of the discharge channel or a central axis of the inlet opening of the vortex chamber. Since the fiber structure is usually guided in such a way that its imaginary central axis extends on the longitudinal axis of the discharge channel or a central axis of the inlet opening, it is ensured in this way that the central guide element is at least partially within the passing fiber structure. bands is located. This, in turn, ensures that at least a portion of the fibers of the fiber composite are forced outward and can be detected by the air flow within the vortex chamber. In contrast, it should be ensured that the guide portions extend outside of said axes in order to allow a guidance of the fiber composite from the outside and thus to prevent the re-planting of the rotation.
- the inlet opening or the wall surrounding the inlet opening can extend at least partially concentrically with the inlet mouth of the outlet channel.
- the fiber composite undergoes no deflection in this case as a whole. Rather, at least the end of the central guide element facing the withdrawal channel lies on a line which corresponds to the imaginary longitudinal axis of the incoming fiber composite.
- the fiber structure is basically rectilinearly guided into the region of the withdrawal channel (even if the described deflection of the fibers takes place in the region of the middle guide element, in which case the fibers are due to the presence of the middle guide element and starting from this preferably uniformly distributed around the circumference of the fiber composite are pushed outwards).
- the guide sections are formed by guide pins or guide plates which, starting from a wall surrounding the inlet opening of the vortex chamber, extend in the direction of the inlet mouth of the yarn formation element. While it has been proven in the case of thorns to provide them with a pointed end, the plates may be rounded off to one or more sides in order to avoid damage to the passing fibers.
- the plates also preferably extend radially inwardly and may, like the guide pins, connected to a wall of the spinning station or be formed integrally therewith. In any case, it has been proven to place the guide sections at equal distances from each other.
- an end of the middle guide element sent to an outlet opening of the withdrawal channel is placed between the inlet mouth of the yarn formation element and the inlet opening of the vortex chamber.
- the said end is located in this case in the area in which the fiber structure passes into the area of the vortex air flow. This ensures that the fibers of the fiber composite are pressed outwards by the guide element running in its interior and are thus increasingly wound around the remaining fibers as wraparound fibers.
- the guide sections can either extend as far as into the mentioned area of the spinning station. However, it is also conceivable that these are placed completely in the inlet opening of the vortex chamber and thus do not reach directly into the flow area of the vortex air flow.
- the middle guide element extends further in the direction of an outlet opening of the draw-off channel than the guide sections. This ensures that the air flow, which surrounds the fiber structure in the region of the end of the central guide element pointing in the direction of the outlet opening, does not hit the outer guide sections of the guide arrangement according to the invention.
- the distance between the middle guide element and the adjacent guide sections may be between one and a few millimeters.
- the guide sections and / or the middle guide element extends into the trigger channel.
- Such an arrangement ensures that the desired effect of the respective component is maintained until the fibers are within the exhaust duct and the swirling air flow is no longer or only slightly exposed.
- the protruding into the flue duct elements should have in this area a cross-sectional area which is less than half (preferably one third) of the cross-sectional area of the inlet mouth of the flue to avoid clogging of the flue.
- the minimum distance between two guide sections is greater than the minimum distance between each guide section and one of an outlet opening of the discharge channel facing the end of the central guide element.
- the end sections of the guide sections facing the outlet opening of the withdrawal channel are placed relatively close to the corresponding end section of the central guide element.
- the fiber structure is inflated at this point by the central guide element from the inside (the individual fibers are in the radial direction - relative to the longitudinal axis of the discharge channel - pushed outward), so that at least the outer fiber ends of the fiber composite come into contact with the guide sections. A reverse rotation of the fiber composite is thereby particularly effectively avoided.
- the guide sections each have an end facing away from an outlet opening of the withdrawal channel and an end facing away from the outlet opening, wherein an end of the middle guide element facing the outlet opening of the withdrawal channel is in a section running parallel to the longitudinal axis of the withdrawal channel is placed between the respective ends of the guide sections.
- the fiber composite must pass through an area in which it is in contact simultaneously with the guide portions acting on it from the outside and the middle guide member extending substantially inside. A re-planting of the yarn twist can be particularly effectively prevented in this way with sufficient number of Umwindemaschinen.
- both the middle guide element and the guide sections each have an end facing the outlet opening of the draw-off channel, said ends of the guide sections being placed concentrically around said end of the middle guide element in a section perpendicular to the longitudinal axis of the draw-off channel.
- the central guide element should be placed centrally in said section, it is advantageous to place the guide sections on a circular path around the centrally arranged central guide element.
- the middle guide element (or its center axis in the region of the end section facing the outlet opening of the draw-off channel) effectively forms the center of a circle to which the speaking end portions of the guide portions are arranged.
- the minimum distance between two guide sections is smaller than the diameter of the discharge channel in the region of the inlet mouth of the yarn formation element.
- a rotation of the fiber composite in the region of the guide arrangement is hereby particularly effectively avoided, in particular if the distance between the guide sections is smaller than the diameter of the yarn produced.
- At least one guide section with the longitudinal axis of the discharge channel forms an angle ⁇ , the amount of a value between 10 ° and 50 °, preferably a value between 20 ° and 40 °, particularly preferably a value between 25 ° and 35 °, occupies.
- the guide sections or the mandrels forming the guide sections should therefore form an acute angle with the longitudinal axis of the withdrawal channel in the transport direction of the fiber composite, in order to allow the guide sections to slide along the fiber structure without mutual entanglement.
- the guide sections should be made flexible in order to be able to preclude cutting of the fiber structure in the longitudinal direction.
- the guide sections and / or the middle guide element are part of an insert which is mounted stationary or movable with respect to the vortex chamber.
- Guide sections and middle guide element are in this case interchangeable with the insert, so that the spinning position quickly adapted to different types of fiber composite and / or dimensions can be.
- the insert is preferably sleeve-shaped.
- the guide sections and / or the middle guide element can also be part of the insert or connected to it. Further advantages of the invention are described in the following exemplary embodiments.
- FIG. 1 shows a detail of a partially cut spinning station of an air spinning machine, a sectional view of a section of a known spinning station of an air spinning machine, a detail of a sectional illustration of an air spinning machine according to the invention (top) and a sectional view along the sectional area AA '(bottom), the area of the inlet opening of the vortex chamber a spinning station according to the invention, and
- FIGS. 5 to 9 show alternative embodiments of the area shown in FIG.
- FIG. 1 shows a schematic view of a detail of an air-jet spinning machine.
- the air-spinning machine can comprise a drafting device 25, which is supplied with a fiber structure 2, for example in the form of a relined conveyor belt.
- the air spinning machine shown comprises a plurality of mutually adjacent spinning stations 22, each with an internal swirl chamber 3, in which the fiber structure 2 or at least a portion of the fibers of the fiber composite 2 is provided with a rotation (the exact operation of the spinning station 22 is hereinafter described in more detail).
- the air-spinning machine, a pair of delivery rollers 26 and a the Take-off roller pair 26 downstream winding device 27 (also shown schematically) with a coil 28 for winding up the spinning unit 22 leaving and the desired rotation having yarn 1 include.
- the device according to the invention need not necessarily have a drafting device 25, as shown in FIG. Also, the take-off roller pair 26 is not mandatory.
- the spinning machine shown operates on an air spinning process.
- the fiber structure 2 is guided via a fiber guide element 24 provided with an inlet opening into the swirl chamber 3 of the spinning station 22 (see also FIG. 2).
- a rotation d. H.
- at least a portion of the free fiber ends 23 of the fiber composite 2 is detected by an air flow, which is generated by correspondingly arranged in a surrounding the vortex chamber 3 wall 21 air nozzles 6.
- a portion of the fibers is thereby pulled out of the fiber structure 2 at least a little bit and wound around the tip of a protruding into the vortex chamber 3 Garn Strukturselements 5.
- the yarn 1 produced can basically be any fiber composite which is characterized in that an outer part of the fibers (so-called Umwindefasem) is wrapped around an inner, preferably untwisted part of the fibers to give the yarn 1 the desired strength.
- an air-spinning machine with the aid of which so-called roving can be produced.
- Roving is a yarn 1 with a relatively small proportion of wraparound fibers, or a yarn 1, in which the wraparound fibers are wound relatively loosely around the inner core, so that the yarn 1 remains deformable. This is crucial if the produced yarn 1 on a subsequent textile machine (For example, a ring spinning machine) is to be distorted again with the help of a drafting system 25 or must, in order to be further processed accordingly.
- the air nozzles 6 it should also be mentioned as a precautionary measure at this point that they should as a rule be aligned so that the exiting air jets are rectified in order to jointly produce a rectified air flow with a direction of rotation.
- the individual air nozzles 6 are arranged in this case rotationally symmetrical to one another.
- the spinning stations 22 known in the prior art preferably also have a swirl-blocking element 29, for example inserted into the fiber-guiding element 24.
- This can, as shown in Figure 2, be formed as a pin partially entwined by the fibers and prevents rotation in the fiber structure 2 propagates counter to the transport direction of the fiber composite 2 and thus in the direction of the inlet opening 4 of the fiber guide element 24.
- the spinning unit 22 according to the invention now has a novel guide assembly 9, which causes a reverse planting of the rotation opposite to the transport direction of the fiber composite 2, without excessively reducing the number of desired Umwindemaschinen.
- the guide arrangement 9 now has at least two guide sections 10 spaced apart from each other (four in FIG. 3) whose mutual spacing decreases (at least in sections) in the transport direction of the fiber composite 2.
- the spinning unit 22 has several, from the outside on the Fiber structure 2 acting elements which converge in the transport direction of the fiber composite 2.
- the fiber structure 2 therefore inevitably comes into contact with the guide sections 10 and is, so to speak, gripped from the outside, so that a rotation thereof in the region of the guide sections 10 is prevented.
- the guide assembly 9 further comprises at least one central guide member 11 which is in a perpendicular extending to the longitudinal axis 12 of the discharge channel 8 section (see Figure 3, bottom view) at least partially extending between the guide portions 10. While now the outer guide portions 10 cause a guiding of the fiber composite 2 "from the outside", the middle guide member 11 is during the yarn production, so to speak, "inside” the fiber composite 2 and thus causes it to be pushed apart.
- the middle guide member 11 takes place by the middle guide member 11, a deflection of the fibers to the outside, or geometrically expressed, perpendicular to a longitudinal axis 12 of the discharge channel 8.
- the free fiber ends 23 are increasingly pressed outward, so that it is ensured that the fibers despite the outer guide portions 0 reach the area of the air flow generated by the air nozzles 6 and can be wound around the fiber core.
- FIGS. 4 to 9 show different examples of the alignment, configuration and mutual arrangement of the guide sections 10 and the middle guide element 11.
- the central guide element 11 does not necessarily have to be present as a guide dome 15 provided with a tip, as can be seen for example in FIG. Rather, other designs are conceivable.
- the central guide element 11 could have a drop-shaped or spherical end, as shown in FIG. This would result in a particularly strong lateral deflection of the fibers and thus an increased number of binder fibers.
- the shape and orientation of the guide portions 10 is not limited to an embodiment in principle. So it would be conceivable, for example, instead of z.
- rod-shaped guide portions 10 to use the indicated in Figure 8 guide plates 14, which also prevent reverse rotation of the fiber composite 2 against the transport direction.
- these should preferably enclose an angle ⁇ with the longitudinal axis 12 of the discharge channel 8 (which is only indicated in FIG. 5 for reasons of clarity in which the wall runs parallel to the longitudinal axis 12 around the inlet opening 4) ), the amount of a value between 10 ° and 50 °, preferably a value between 20 ° and 40 °, particularly preferably a value between 25 ° and 35 ° occupies.
- end 18 of the middle guide element 11 facing the outlet opening 17 of the discharge channel 8 is in a section running parallel to the longitudinal axis 12 of the discharge channel 8 (corresponding to the illustrations according to FIGS. 4 to 9) between the outlet opening 17 of FIG Discharge channels 8 facing ends 19 of the guide portions 10 and the outlet opening 17 of the discharge channel 8 facing away from the ends 20 thereof. In this way, it is ensured that the fiber structure 2 is in contact with the outer guide sections 10 and the middle guide element 1 at least in one section of the guide arrangement 9 at the same time.
- the central guide element 11 (or its outlet opening 17 of the discharge channel 8 facing end 18) should run on the longitudinal axis 12 of the discharge channel 8, which may be arranged again co-linear with the central axis 13 of the inlet opening 4 ,
- the fiber structure 2 thus meets centrally on the middle guide element 11 and is deflected accordingly laterally, since it must pass through the middle guide element 11.
- the guide portions 10 and the middle guide member 11 z. B. from the inlet opening 4 surrounding wall 16 may be directed in the direction of Garn Strukturselements 5.
- an insert 30 for example, a sleeve-shaped design indicated in FIG. 9 could be used, which comprises the guide sections 10 and / or the middle guide element 11 or to which said components are fastened.
