Definitions

  • the present invention relates to a roving machine for producing a roving to form a fiber structure, and to the use of a swirl imparting agent which works according to an air spinning process, a process for producing a roving, and a draw frame / roving machine combination according to the preamble of independent patent claims 1. 2, 10, 14, and 18.
  • the roving machines according to the present invention include, in particular, the so-called flyers.
  • the flyers are used for the production of roving or for the production of a so-called roving sliver.
  • the roving serves as a template for the spinning process, i.e. H. for spinning the fibers into a fiber yarn, for example on a ring spinning machine.
  • the sliver coming from the Vortechnik (carding machine) is usually first duplicated with the help of drafting systems and placed in cans.
  • the resulting conveyor belt is then submitted to the roving machines for further processing.
  • the draw frame is usually first drawn in its own drafting system and then twisted slightly by means of a suitable twist before the original sliver is wound onto a feed spool as roving.
  • the resulting roving (also known as fiber sliver, flyer sliver or generally sliver) usually serves as a template for ring spinning machines.
  • the roving machine usually has its own drafting system, usually a double apron drafting system.
  • the fiber structure After being warped by the drafting machine of the pre-spinning machine, the fiber structure is given a slight twist (so-called protective twist) so that the resulting fuse has a certain strength and can be wound on a spool and does not disintegrate.
  • the rotation given must only be so high that the cohesion of the fiber structure is tight enough for winding and unwinding, as well as the transport of the bobbins, so that, in particular, no misalignments (thin spots in the roving) occur.
  • the rotation must be easily resolvable or the roving must be draftable so that the subsequent spinning process, e.g. B. can be accomplished in a ring spinning machine.
  • the so-called flyer which produces the corresponding flyer fuse, is generally used as the pre-spinning machine.
  • This pre-spinning machine is equipped with a drafting system and a spindle for winding the flyer sliver onto a solenoid by means of a wing to support the sliver against the centrifugal force caused by the spindle speeds.
  • the flyer is an expensive machine in the entire spinning process, especially because of the complicated winding mechanism.
  • the usual performance of a flyer is 20 - 25 meters of roving per minute.
  • this low production cannot be increased with regard to the winding system with flyer wings, since a higher speed is limited by the centrifugal force that the wings and roving spool have to endure.
  • EP 375 242 A2 One possibility of replacing the flyer is disclosed in EP 375 242 A2.
  • a machine for producing a roving from a fiber assembly which has a twist distribution means with a rotating rotor.
  • the rotor has a continuous longitudinal bore on its axis of rotation, through which the fiber assembly to be twisted is guided.
  • the rotor has a plurality of rotationally symmetrically arranged bores going in the radial direction. These radial bores connect the longitudinal bore through which the fiber structure is guided with the outer surface of the rotor. This outer surface of the rotor is exposed to a vacuum or a strong negative pressure.
  • the device according to the cited document is relatively complex to manufacture and operate because of the mechanical elements (rotating rotor) and the vacuum technology.
  • the swirl in the first pneumatic swirl chamber is opposite to the subsequent swirl in the second pneumatic swirl chamber (e.g. the first swirl causes a left turn, while the subsequent swirl in the second swirl chamber causes a right turn). In this way, a yarn is produced according to the so-called false wire spinning process).
  • a false wire nozzle is used to produce a staple fiber yarn (also a false wire spinning process).
  • the object of the present invention is to provide a roving machine and a method for producing a roving in which the above-mentioned disadvantages of conventional roving machines can be avoided and in which a roving is produced which has the properties of conventional leaf sliver or roving, this relates in particular to the warpability of the roving produced.
  • FIG. 1 shows schematically a spinning station 1 of a roving machine (entire roving machine not shown) according to the invention.
  • This possible embodiment of the invention has a drafting device 2 (also shown schematically), which is supplied with a fiber structure 3 (for example a doubled conveyor belt).
  • the (stretched) fiber structure 3 then arrives from the drafting device into the swirl distribution means 4.
  • the fiber structure 3 becomes a preliminary yarn 9 twisted, ie at least partially (ie at least part of the fibers of the fiber assembly) the fiber assembly is given a real twist.
  • FIG. 1 shows a draw-off roller pair 8 with a clamping line 34 and a winding device 7 (also shown schematically) for the roving 9.
  • the device according to the invention does not necessarily have to have a drafting device 2, as shown in FIG. 1, as well few a draw-off roller pair 8.
  • a drafting device 2 as shown in FIG. 1, as well few a draw-off roller pair 8.
  • an actual conventional draw frame can be provided within the same machine (hereinafter referred to as "combination") (not shown).
  • Such a draw frame / spinning machine combination has the advantage of shortening the process ,
  • the swirl imparting means 4 works according to the so-called vortex process, a special air spinning process.
  • the vortex air spinning process is known per se as a yarn spinning process.
  • devices for yarn formation per se are unsuitable for the production of a warpable roving.
  • tests with suitably modified air spinning devices have shown that certain air spinning processes are also suitable for the production of rovings. To do this, however, the dimensions and the flow conditions of conventional yarn air spinning devices have to be adapted.
  • the twist distribution means according to the invention only have to give the fiber structure a protective twist so that the sliver or roving formed thereby remains draftable.
  • Conventional conventional air spinning devices rotate the fiber structure in such a way that a yarn or thread is formed which is twisted to such an extent that the rotation is irreversible and, in particular, is no longer deformable.
  • warpable rovings or slips can also be produced with air spinning devices. The corresponding conditions can best be determined experimentally.
  • air spinning devices for rovings preferably have one or more of the following properties: -
  • the diameter of the swirl or swirl chamber is preferably at least 5 mm (see swirl chamber 5 in the figures described below)
  • the delivery speed of the fiber structure is preferably at least 200 m / min - the pressure is preferably Air flow before it flows through the nozzle bores or nozzles into the swirl chamber, at most 5 bar (see air flow 32, 16, 16.1, 16.2, or 20, and nozzle bores or nozzles 11 in the figures described below) - preferably these air spinning devices give this Roving or the slub a deep twist, preferably the twist or the twist coefficient ⁇ m is less than 100.
  • the mode of operation of the device for forming a roving according to the invention is similar to the mode of operation of conventional air spinning processes for yarn formation. For this reason, the air spinning process is not dealt with in great detail here.
  • a protective twist is given to the fiber structure or roving in the devices and methods according to the invention. This protective twist is such that the roving remains draftable for the further processing and the turning process could even be reversed. Accordingly, it is or would be reversible in contrast to the rotation, which a fiber structure with conventional d. H. known air spinning devices would be issued.
  • the fiber structure is at least partially given a real twist, i.e. H.
  • the fibers of the fiber structure are given a real twist (rotation) by means of an air flow.
  • this real twist or this rotation is only a protective rotation.
  • the roving or sliver produced according to the invention therefore has the same properties as a sliver produced with a conventional flyer.
  • twist-imparting means 4 works according to the so-called vortex air spinning method.
  • the device 4 has a fiber guide element 10, with which the fiber structure 3 is delivered into the swirl chamber 5 of the swirl distribution means 4.
  • a fluid device (not shown in more detail) generates an air flow 32 or a swirl flow by means of one or more nozzle bores 11.
  • the resulting swirl flow within the swirl chamber 5 causes individual free fiber ends 12 on the surface of the fiber assembly 3 around the inlet opening 13 of the roving formation element 6 and - captured by the rotating vortex flow in the vortex chamber - rotate around the core 14 of the fiber composite.
  • the fiber assembly 3 in the swirl chamber 5 is at least partially (i.e. at least a part of the fibers) given a real twist by means of an air flow 32.
  • This air flow thus causes at least a part of the fiber structure, i.e. H. individual fibers, a real twist or a real rotation around a core of largely parallel permanent fibers is issued.
  • the roving 9 thus created at the inlet mouth 13 is drawn off, for example, via a pair of draw-off rollers 8 and wound onto a winding device 7.
  • the roving element 6 has a bore (see FIG. 1).
  • the winding device 7 in FIG. 1 is only shown schematically.
  • the winding device can be a cross winder, a precision cross winder, a wild cross winder, a step precision winder or a parallel winder.
  • FIG. 2 shows the swirl distribution means 4 from FIG. 1 in another view. It can be seen particularly clearly in this figure how the fiber structure 3 is guided through the fiber guide element 10 into the swirl chamber 5, where a vortex air flow generated by the nozzle bores 11 detects the free fiber ends 12 of the fiber structure 3 and places it around the inlet opening 13 of the roving formation element 6 , The free fiber ends 12 lying around the inlet mouth 13 form one "Sun" rotating around the core 14 of the fiber structure.
  • the free fiber ends 12 thus twist around the core 14 of the fiber structure, as a result of which the fiber structure 3 in the swirl chamber 5 at least partially receives a real twist (rotation) due to the air flow 13 roving 9 produced is drawn off by the roving formation element 6 (for example a spindle as shown here) (see arrow).
  • the roving formation element 6 for example a spindle as shown here
  • FIG. 3 shows another twist distribution means 15 according to the invention, which, however, has no roving element.
  • the swirl distribution means 15 (shown schematically) also has a swirl chamber 5, in which an air flow 16 (swirl flow) is generated by means of one or more nozzle bores 11. By means of this air flow 16, the fiber structure is at least partially given a real twist in the swirl chamber 5.
  • the real twist distribution (real rotation in the fiber structure) is shown in FIG. 3a: within the swirl chamber 5, the air structure 16 gives rotation to the fiber structure 3, i. H. at least some of the fibers of the fiber structure 3 are twisted so that the fuse 9 is formed.
  • FIG. 3b shows a variant of the swirl distribution means according to FIG. 3a.
  • the twist distribution means 17 has two swirl chambers 5, each of which has no roving element.
  • the real twist is also given here by means of one or in this case two air flows 16.1 and 16.2.
  • At least some of the fibers of the fiber structure 3 receive a real twist (rotation).
  • the roving 9 or the sliver is drawn off and wound up by a device (not shown).
  • the swirl distribution means 17 preferably has a plurality of nozzle bores 11.
  • the nozzle bores 11 serve to generate the air flows 16.1 and 16.2.
  • the nozzle bores are aligned in such a way that the emerging air jets together and together produce the air flow 16.1 or 16.2.
  • the entry angles of the nozzle bores 11 within the respective swirl chamber 5 are preferably the same.
  • the air flows 16.1 and 16.2 are also the same directs, ie that the two air flows 16.1 and 16.2 - despite separate vortex chambers - have the same direction of rotation (right or left rotating air flow).
  • the individual nozzles or nozzle bores are preferably arranged rotationally symmetrically to one another.
  • the swirl distribution means according to the invention preferably also have one or more swirl stowage elements.
  • Swirl jam elements can have different occurrences.
  • a swirl congestion element can be designed, for example, as an edge, as a pin, as a twisted surface, as a cone or in the form of several steering means.
  • FIG. 4 shows a swirl imparting means 18 with a swirl accumulation element in the form of a pin 19.
  • Pin 19 in FIG. 4 serves as a twist accumulation element and also as a wrong yarn core. Twist jam elements serve to prevent a rotation in the fiber structure from propagating further back. In particular, this prevents a possible wrong twist and thus at most no real twist is given to the fiber structure.
  • the use of swirl congestion elements for the devices and methods according to the invention is not absolutely necessary, but is recommended. In particular, this improves the real twist distribution by means of the air flow.
  • a pin 19 prevents the rotation generated by the air flow from propagating further back towards the entrance of the fiber guide element in the fiber structure 3.
  • the air flow 20 around the mouth of the roving formation element (not shown) produces a twist or a twist within the fiber structure 3. Due to the presence of the pin 19 as a twist jam Element is prevented that the rotation of the fibers is transferred to the fiber structure 3, which lies on the fiber guide element 10 or 21 (see parallel untwisted fibers on the fiber guide elements 10 or 21 in the figures).
  • a twisted fiber guiding surface 21 can also serve as a swirl jam element.
  • FIG. 4b shows a twisted fiber guide surface 21, which additionally has a pin 19. This makes the swirl function particularly effective.
  • a twisted fiber guide surface 21 with a pin is also shown in FIG. 4c.
  • the elements of FIG. 4c largely correspond to the elements of FIG. 4b with the difference that pin 19 of FIG. 4c is blunt.
  • FIG. 5 shows a fiber guide element 10 with a so-called twist-stop cone 24.
  • the twist-stop cone 24 performs the function of the twist-stopping element.
  • the mode of action is the same as for pin 19: cones or pins also serve as so-called false yarn cores.
  • the fibers or the fiber structure are wrapped in a spiral around the wrong yarn core, which prevents the rotation from propagating against the direction of withdrawal of the roving or fiber structure.
  • a twisted fiber guide element 22 without a pin can also serve as a swirling element. This is shown, for example, in FIG. 6 (compare with FIG. 4c).
  • a twisted fiber guiding surface is in itself sufficient as a swirl stowage element.
  • the additional use of a pin is not absolutely necessary.
  • Different views of a tortured fiber guide element without pin 22 are given in FIGS. 6a and 6b. Only one edge 33, which does not necessarily have to be preceded by a twisted fiber guiding surface, can also serve as a swirling element.
  • FIG. 7 shows further swirl congestion elements which could be used in the device according to the invention.
  • the figure shows a fiber guide element 23 with several steering means. In addition to their function of steering the fiber composite 3, these steering means 26 also have the effect of a swirl stop.
  • the figure clearly shows how the steering means 26 with a swirl function function: the fiber structure 3 is pulled in the untwisted state in the direction of the roving formation element 6.
  • the free fiber ends 12 are twisted by the air flow 20 of the swirl chamber by real twist. The twisting of the free fiber ends 12 creates a torsional moment which tries to propagate in the fiber structure 3 against the direction of withdrawal (arrow) of the roving.
  • FIGS. 8a and 8b show steering means with a swirl-stopping function of different shapes.
