Description
Technical Field
The invention relates to a work station of an air jet spinning machine, comprising a spinning nozzle for producing a yarn from a fiber bundle fed to the spinning nozzle, wherein the spinning nozzle comprises an internal swirl chamber and an inlet for the fiber bundle. The spinneret further comprises a yarn forming element extending at least partially into the swirling chamber, wherein the spinneret further has an air nozzle for feeding air into the swirling chamber to impart a twist to the fiber bundle in the region of the yarn forming element. The spinneret has an outlet for withdrawing yarn from the vortex chamber. The spinneret also has at least two spinneret sections which delimit the swirling chamber on the outside, wherein a first of the at least two spinneret sections has the inlet for the fiber strand and a second of the at least two spinneret sections has the outlet for the yarn, and wherein the second spinneret section is mounted such that it can be moved relative to the first spinneret section and at least partially linearly from a closed position into an open position, wherein the yarn-forming elements are accessible and cleanable by an operator in the open position.
The invention also describes a method for opening a spinneret of an air jet spinning machine for producing a yarn from a fiber bundle by means of an air stream, wherein the spinneret has at least one first spinneret section which comprises an inlet for the fiber bundle and one second spinneret section which comprises an outlet for the yarn, wherein the first spinneret section and the second spinneret section delimit on the outside a built-in swirl chamber, wherein the spinneret comprises a yarn-forming element which projects into the swirl chamber, wherein the second spinneret section is moved relative to the first spinneret section during opening and in this case is moved at least partially linearly from a closed position into an open position, and wherein in the open position of the second spinneret section the yarn-forming element is accessible and cleanable for an operator.
Background
The same type of spinneret is used for producing yarns from elongated fiber bundles by means of air vortices which are generated in a vortex chamber by corresponding air nozzles. In this case, in the region of the entry opening of the yarn-forming element, which is usually spindle-shaped, the outer fibers of the fiber bundle are wound around the fibers (core fibers) which are located inside, so that as a result a yarn is formed which can finally be drawn off from the swirl chamber through the draw-off channel of the yarn-forming element and wound onto a drum by the winding device.
In order to be able to clean the interior of the spinneret, in particular the yarn-forming elements, manually after the spinning has stopped or by means of an automatic handling device, it has already been proposed to design the housing of the spinneret surrounding the swirl chamber as a composite. In this case, the housing segments are mounted so as to be movable relative to one another, so that the housing can be opened by movement of one or more housing segments. After opening, the internal cavity of the spinneret is accessible and deposits (brightening agents, honey colors, etc.) can be removed from the internal cavity.
Various opening mechanisms have been disclosed (see for example EP 2573220 a2 or DE 102015100825 a 1).
Disclosure of Invention
It is therefore an object of the present invention to improve spinnerets of the same type and to provide an improved method of opening spinnerets.
The solution of the invention to achieve the object is a work station and a method having the features of the independent claims.
According to the invention, the work station is characterized in that the first spinneret section is mounted so as to be movable away from the second spinneret section starting from a basic position. The accessibility of the yarn-forming elements is thereby further enhanced, in particular when the second spinneret section is already in its open position. That is, the first spinneret section can move before or after it moves into its open position, or during the time the first spinneret section enters this open position. The movement of the two spinneret sections can be coupled to each other or independent of each other.
In any case, both spinneret sections can be moved from the starting position into the second position, so that the interior of the spinneret, in particular the yarn-forming elements, is exposed as far as possible, and the accessibility from the outside is maximized.
The first and/or second spinneret sections are preferably movably supported (e.g., by one or more rails or one or more deflection shafts) on a carrier of the spinneret. Preferably, the two spinneret sections are movable relative to the carrier independently of each other or coupled to each other. Preferably, the yarn-forming elements are part of the second spinneret section.
In each case, several spinneret sections are provided, which are mounted so as to be movable relative to one another. If the second spinneret section is moved into its open position and the first spinneret section is moved out of its basic position into another position, the yarn forming elements or the swirling chamber can be cleaned manually or by means of a cleaning device from the outside.
Furthermore, the spinneret is preferably mounted such that the spinneret can be moved back and forth between at least two positions, in particular by deflection. That is, in this case, the spinneret can move as a whole. The support of the spinneret and of the two spinneret sections can be designed such that the first spinneret section can be moved from its basic position into another position or, in the case of a movement of the spinneret as a whole, can be moved automatically by means of corresponding guides.
In addition or alternatively, the second spinneret section can be moved from its closed position into its open position or, in the case of a movement of the spinneret as a whole, can be moved automatically by means of a corresponding guide device. That is, both spinneret sections can be moved in the same direction at one time as part of a spinneret moving as a unit. In addition, independent movement of each spinneret section can be achieved.
Preferably, the spinneret has or is operatively connected to at least one guide device, which, during or after the movement, preferably deflection, of the spinneret as a whole, brings about a movement of the second spinneret section. The movement of the spinneret as a whole is preferably carried out by means of a pneumatic or electric actuating element. It is also preferred that the second spinneret section is automatically moved relative to the carrier and/or relative to the first spinneret section, with the spinneret moving as a unit. This solution can be realized by one or several corresponding guides and/or slides.
Particularly preferably, the first and/or the second spinneret section are supported in such a way that the first spinneret section can only be deflected relative to the second spinneret section. The movement may be given by one or several forms, for example a deflection axis of the pin.
Preferably, the first spinneret section is supported on the carrier by means of one or several deflection shafts, on which carrier the second spinneret section is also supported and which can preferably be moved by means of one or several guide devices.
Preferably, the second spinneret section is only movable relative to the first spinneret section. Preferably, the spinneret and the two spinneret sections are supported such that the entire spinneret can be deflected about a deflection axis, such that the second spinneret section as part of the spinneret is deflected during the deflection of the spinneret and can also be moved relative to the first spinneret section. Finally, the first spinneret section is preferably deflected as part of the spinneret during deflection of the spinneret and can also be deflected relative to the second spinneret section. The deflection axis about which the spinneret as a whole deflects and the deflection axis about which the first spinneret section deflects preferably exist as separate deflection axes. The two deflection axes preferably do not extend colinearly and, in particular, extend parallel.
Also preferably, the first and second spinneret sections are supported on the same carrier. The carrier is preferably deflectable about the aforementioned deflection axis and is fastened by means of one or more deflection pins or deflection pin receptacles to a preferably stationary and/or rigidly supported holding section of the spinneret or to a holding section of the working station or spinning machine. In the case of a movement of the first and second spinneret sections from the spinning position into the maintenance position, the inlet and the outlet are moved in different directions, in particular relative to the carrier. In the spinning position, the second spinneret section is in its closed position and the first spinneret section is in its basic position.
The second spinneret section preferably has a sleeve-like section which at least partially surrounds the yarn-forming elements. Furthermore, with the first spinneret section in its basic position and the second spinneret section in its closed position, the sleeve-shaped section should be in contact with the first spinneret section and in this case close the swirl chamber at least partially on the outside.
The sleeve-shaped section can in particular be substantially shell-shaped or bell-shaped. In the case of the first spinneret section being in its basic position and the second spinneret section being in its closed position, said sections are preferably at a distance from the yarn-forming elements at least in the region of contact with the first spinneret section. A free space is delimited by the distance, which is the swirl chamber or participates in the formation of the swirl chamber.
The sleeve-shaped section preferably surrounds the thread-forming element at least in some regions in an annular manner and delimits the swirl chamber together with the thread-forming element. The sleeve-shaped section preferably has at least in sections the shape of a cylindrical wall. In the case of a spinneret in the above-mentioned spinning position, the swirl chamber is preferably delimited by one of the sleeve-shaped section, the second spinneret section, which extends between this sleeve-shaped section and the yarn-forming element, and the first spinneret section.
The sleeve-shaped section preferably has at least one cutout or one perforation, through which air can flow out of the swirl chamber when the first spinneret section is in its basic position and the second spinneret section is in its closed position. The slit is preferably delimited by the sleeve-shaped section and the first spinneret section with the spinneret in its spinning position. In this position, the slit or alternatively the perforation provided is adjacent to an air outlet (for example an air outlet), which may be formed by a pipe section, which in turn may be connected to a negative pressure source of the air jet spinning machine.
It is also preferred that the first spinneret section is in form-fitting contact with the second spinneret section and/or that the first spinneret section and/or the second spinneret section is in form-fitting contact with a carrier of the spinneret, so that the first and/or the second spinneret section is/are prevented from twisting about the central axis of the spinning channel with the outlet. That is, the first and second spinneret sections can only be loaded into the work position in predetermined positions. The second spinneret section is to be connected to the carrier in a form-fitting manner, in particular at least in its closed position, preferably also in its open position. The form fit is designed such that the cutouts or perforations of the second spinneret section are always located in the same position when the second spinneret section is in its closed position. In this position, the cut-outs or perforations should always be aligned with the air outlets such that air can flow out of the swirl chamber through the air outlets.
In particular, the first spinneret section is preferably supported or fastened to the second spinneret section or to a carrier of the spinneret or to a holding section of the work station in such a way that the first spinneret section can be completely separated from the second spinneret section or from the carrier after the at least one fastening member has been released. That is, the first spinneret section can preferably be completely removed from the work station. This makes the swirl chamber particularly accessible. Furthermore, it is desirable to be able to manually remove the first spinneret section or loosen at least one fastening member without the use of tools. For example, fastening means in the form of one or several snap-fit connections or clip connections or nuts may be employed, which can be loosened manually (e.g. wing nuts).
In a particularly preferred embodiment, the first spinneret section is fixed to the carrier or the second spinneret section by means of one or more magnets. In this case, the magnet may be part of the first spinneret section and/or the second spinneret section and/or the carrier. By means of this fastening of the first spinneret section, the first spinneret section can simply be completely removed from the second spinneret section, so that the cleaning of the inner space of the spinneret, in particular of the swirl chamber or the yarn-forming elements of the spinneret, is particularly simple.
In addition, the first spinneret section preferably has one or several recesses and/or projections which, in the case of a connection of the first spinneret section to the second spinneret section, interact with one or several projections and/or recesses of the second spinneret section or of the carrier. This ensures that the first spinneret section can only be connected to the second spinneret section in a specific position, so that a precise positioning of the first spinneret section relative to the second spinneret section is achieved. The first (or second) spinneret section can have, for example, one or several pins which, in the case of two spinneret sections connected, engage in corresponding bores of the second (or first) spinneret section.
Furthermore, a seal is preferably provided between the first spinneret section and the second spinneret section. If the spinneret is in the spinning position described above, the two spinneret sections are pressed against one another, with the seal located between the spinneret sections and preventing undesired exit of air in the event that air is fed into the swirl chamber through the air nozzles.
Preferably, the first spinneret section is operatively connected to an actuator (e.g., a pneumatic cylinder) or an accumulator (e.g., an extension spring or a compression spring) which presses or pulls the first spinneret section towards the second spinneret section or the seal during the spinning mode in the working position. This seals the swirl chamber from the outside, wherein the spinneret can have an air outlet through which the air fed through the air nozzle can flow out of the spinneret again. Furthermore, the escape of air can also be achieved via the outlet and/or the inlet of the spinneret.
Preferably, the first spinneret section can be manually moved, e.g., deflected, from its basic position to another position in opposition to the force of the actuator. If no or only a small manual force is applied to the first spinneret section, this first spinneret section is brought back into its basic position by the force applied by the actuator and in this case is pressed or pulled towards the second spinneret section. Furthermore, a corresponding actuator may be provided, which is adapted to deflect the spinneret as a whole between the two positions.
The method according to the invention for opening a spinneret of an air jet spinning machine, comprising at least two spinneret sections, is characterized in that the second spinneret section is mounted in such a way that it can be moved from a closed position into an open position relative to the first spinneret section. In this case, the movement is performed at least partially linearly. In addition, in the open position, the yarn-forming element is accessible and cleanable by an operator. Furthermore, the first spinneret section is moved away from the second spinneret section during opening from the basic position, so that the accessibility of the yarn-forming elements is further increased.
That is, the spinneret can be opened by movement of at least the first and second spinneret sections to remove impurities from the interior of the spinneret. Preferably, the second spinneret section is only linearly moved relative to the first spinneret section. That is, the spinneret can be opened by different ways of movement of the two spinneret sections.
Further, the spinneret may have one or more of the features previously or hereinafter mentioned.
It is also preferred that the spinneret is also moved, preferably deflected, during the opening of the spinneret. That is, the spinneret is moved as a unit during opening, while the two spinneret sections are also moved as described above. That is, as a result, it is preferred to deflect the second spinneret section as part of the spinneret and then or during the deflection move linearly. Such that the first spinneret section is also deflected as part of the spinneret about a first deflection axis and is subsequently or independently moved during deflection.
Furthermore, it is preferred that the first spinneret section is deflected from its basic position relative to the second spinneret section during the opening process. Preferably, the first spinneret section is only deflectable relative to the second spinneret section. Preferably, said first spinneret section is deflected about a deflection axis which is different from the deflection axis about which the spinneret as a whole is deflected. The two deflection axes preferably extend parallel.
It is also preferred that during the opening of the spinneret, the second spinneret section is first moved and, after the start or completion of this movement, the first spinneret section is moved, wherein the opening degree of the spinneret is increased in each movement. The movement of the first spinneret section is preferably performed after the movement of the second spinneret section is completed. The second spinneret section is preferably moved during deflection of the spinneret as a whole.
In particular, it is also preferred if the first spinneret section is completely removed from the second spinneret section, if necessary, in order to clean the interior of the spinneret. That is, the first spinneret section is not deflected relative to the second spinneret section in this case. Specifically, the first spinneret section is completely separated from the second spinneret section, wherein the connection between the first spinneret section and the second spinneret section can be achieved, for example, by means of magnets. The corresponding connection by means of magnetic force is easily released, in that the first spinneret section is moved away from the second spinneret section.

Detailed Description
Fig. 1 shows a cut-out 13 of a spinning field of an air jet spinning machine according to the invention (wherein the air jet spinning machine may of course also have several working positions preferably arranged next to one another). The work station may optionally comprise a drawing frame with several roller pairs 18 (only one of which is shown), which is supplied with fiber bundles 3 in the form of, for example, a combined drawing sliver (Streckenband). The working station shown also comprises a spinneret 1, which is shown in detail in fig. 1 in a sectional view, with an internally arranged swirl chamber 4 in which the fiber bundle 3 or at least a part of the fibers of the fiber bundle 3 is twisted after passing through an inlet 5 of the spinneret 1.
Furthermore, the work station may comprise a pair of withdrawal rolls arranged downstream of the spinneret 1, and a winding device arranged downstream of the pair of withdrawal rolls for winding the yarn 2 leaving the work station onto a spool. The work station of the present invention does not need to have a drafting device. Nor is a pair of withdrawal rolls necessary.
In general, the operating position shown operates according to the air jet spinning method. To form the yarn 2, the fiber bundle 3 is introduced into the swirling chamber 4 of the spinneret 1 through an inlet 5. The yarn obtains a certain twist there, i.e. at least a part of the free fiber ends of the fiber bundle 3 is captured by the air vortex generated by the air nozzles 7 correspondingly provided in the housing wall enclosing the vortex chamber 4 (wherein the air nozzles 7 may be connected by an air passage 19 which in turn is connected with the air supply system 14 which is fed with compressed air by a compressed air supply system).
In this case, a portion of the fibers is drawn off from the fiber bundle 3 at least to some extent and is wound onto the front region of the yarn-forming elements 6 which project into the swirl chamber 4. Since the fiber bundle 3 is drawn out of the swirl chamber 4 via the inlet opening 26 of the yarn-forming element 6 through the draw-off channel 16 provided in the yarn-forming element 6 and finally through the outlet 8 from the spinneret 1, the free fiber end is finally also wound as a so-called wound fiber around a centrally extending core fiber, resulting in a yarn 2 with the desired twist. The compressed air fed through the air nozzles 7 finally leaves the spinneret 1 through the draw-off channel 16 and possibly an air outlet 25, which can optionally be connected to a source of underpressure.
In general, it should be noted here that the yarn 2 produced may be any fiber bundle 3 having the following characteristics: the outer part of the fibre (the so-called wound fibre) is wound around the inner, preferably untwisted or optionally also twisted, part of the fibre, giving the yarn 2 the desired strength. That is, the invention also covers an air jet spinning machine, by means of which so-called rovings can be produced. By roving is meant a yarn 2 having a relatively small proportion of the wound fibres, or a yarn 2 in which the wound fibres are wound relatively loosely around the core, so that the yarn 2 remains free of deformations. This solution is of importance in the following situations: it is also necessary or necessary to deform the produced yarn 2 by means of a drafting device on a subsequent textile machine (e.g. a ring spinning machine) in order to correspondingly further process the yarn.
The core of the invention can be seen by combining fig. 2 to 5, which are schematic views of a spinneret 1 of an air jet spinning machine (a drawing device not shown is located below the spinneret 1 shown in the drawings).
In principle, the spinneret 1 comprises at least one first spinneret section 9 and one second spinneret section 10, which together enclose the inner swirl chamber 4. The two spinneret sections 9, 10 are preferably supported on a common carrier 11, which in turn is supported on a holding section 22, for example a frame element, in the operating position.
As can be seen from a comparison of fig. 2 and 3, the spinneret 1 can be deflected by its carrier 11 as a whole about the first deflection axis 20 and relative to the holding section 22.
In addition to the deflection, a movement of the first spinneret section 9 and the second spinneret section 10 can also be realized. Preferably, the second spinneret section 10 is capable of moving linearly along a linear guide (which may be part of the carrier 11) during or after deflection of the spinneret 1.
In this connection, the movement can be carried out automatically when the spinneret 1 is deflected. For example, pneumatic cylinders can be provided, which cause deflection of the spinneret 1. If the second spinneret section 10 is connected to the holding section 22 by means of a guide rod or another guide, the movement of the second spinneret section 10 also takes place during the deflection of the spinneret 1.
In any case, the second spinneret section 10 can be moved, preferably linearly, into an open position as shown in fig. 4. In this position, the interior of the swirling chamber 4 or the yarn-forming element 6 is already accessible from the outside, so that said region can be cleaned of impurities (in the form of, for example, fiber residues or brightening agents).
In order to further improve the accessibility of the interior of the spinneret 1, the first spinneret section 9 can also be moved relative to the second spinneret section 10 according to the invention. Preferably, the first spinneret section 9 is supported on the carrier 11 by a second deflection axis 21 and can be deflected about this deflection axis.
The first spinneret section 9 can in particular be operatively connected to an actuator 17, which applies a force to the first spinneret section 9, which force, without further external forces, moves the first spinneret section into the basic position shown in fig. 4 or holds it there. In fig. 2 to 5, the actuator 17 is represented as a coil spring.
If a force is applied to the first spinneret section 9 (e.g., manually) in opposition to the force generated by the actuator 17, this first spinneret section is rotated into the position shown in fig. 5. The spinneret 1 is now particularly widely open, so that the cleaning of the interior of the spinneret 1 is further simplified.
The first and second spinneret sections 9, 10 can likewise be held together primarily or exclusively by means of one or several magnets, not shown. If a force greater than the holding force of the magnet is applied to the first spinneret section 9, for example by the hand of an operator, the first spinneret section 9 can be completely removed from the second spinneret section 10.
Fig. 6 shows an advantageous embodiment of the second spinneret section 10, wherein not all features, such as possible support or guide elements, are shown.
In principle, the second spinneret section 10 preferably has a sleeve-like section 12 which is open toward the entry opening 26 of the yarn-forming element 6, which is connected to the draw-off channel 16. Thus, when the second spinneret section 10 is abutted against the first spinneret section 9 as shown in fig. 2, the sleeve-like section 12 laterally delimits a cavity, shown in black, which is part of the swirl chamber 4.
The sleeve-like section 12 can have a cutout 13 through which air can escape or be drawn off from the spinneret 1 in the position shown in fig. 2. This air finally flows out of the swirl chamber 4 through the air outlet 25 as shown in fig. 1, wherein this is preferred since during spinning air continuously flows into the swirl chamber 4 through the air nozzle 7.
Finally, as shown in fig. 6, the second spinneret section 10 can have an anti-twist protection in the form of, for example, the illustrated projections 23, which engage in recesses of the carrier 11 when the second spinneret section 10 is correctly mounted relative to the central axis 15 of the draw channel 16. The twist-proof protection thereby ensures: the cut-out 13 is always in the area of the air outlet 25 when the bushing 1 is mounted or assembled.
Finally, as shown in fig. 6, the second spinneret section 10 can have a seal 24, which sealingly abuts against the first spinneret section 9 when the two spinneret sections 9, 10 are in the position shown in fig. 2. Of course, the seal 24 can also be arranged in the region of the first spinneret section 9.
The invention is not limited to the embodiments shown and described. Variations within the scope of the claims, and any combination of features shown and described, even in different parts of the description or claims, or in different embodiments, are possible without departing from the principle of the independent claims.
