Definitions

  • the present invention relates to a method for producing a textile fiber composite, in which a fiber mass is separated into individual fibers by means of an opening roller integrated in a housing and the fibers leave the housing through a fiber outlet opening by being detached from the opening roller at the latest at a knock-off edge of the fiber outlet opening and enter a fiber feed channel, wherein the fiber feed channel is aligned to a fiber collection surface and has an opening and the fibers are then fed to the surrounding, perforated, vacuumed fiber collection surface, deposited there, compacted and transported away.
  • the invention further relates to a device for producing a textile fiber composite, with an opening roller that separates a fiber mass into individual fibers and with a peripheral, perforated, suckable fiber collection surface that is arranged above a suction channel and where the opening roller is arranged in a housing and that housing has a fiber feed opening and a fiber outlet opening, a knock-off edge and a fiber feed channel are arranged on the fiber outlet opening of the opening roller housing, with the fiber feed channel being aligned towards the fiber collection surface and having an opening and a fiber guide surface of the fiber feed channel adjoining the knock-off edge and the suctioned fiber guide surface following the fiber guide surface
  • Fiber collecting surface is arranged and opposite the fiber guiding surface a top surface of the fiber feed channel is arranged and facing away from the opening roller ends of the fiber guiding surface and de r top surface form the mouth of the fiber feed channel.
  • the dissolving of a fiber mass into individual fibers by means of a dissolving roller is widely used in staple fiber processing. through the When the fiber mass is dissolved, it is freed from shell particles and other dirt and the fibers are parallelized. The parallel fibers are then fed to a tape or yarn formation. The fibers are removed from the opening roller by means of negative pressure in a shielded fiber guide channel or by means of slowly rotating removal rollers. Both methods lead to a certain degree of disorientation of the fibers both in the air flow and due to compression during mechanical removal.
  • the fibers are deposited on the fiber collection surface in a compacted manner by suction on a perforation track guided via a suction opening, and the fiber bundle that is compacted on the fiber collection surface and discharged from the deposition area as a fiber sliver without rotation is fed directly to a rotation device that imparts a real rotation, which solidifies it into a yarn.
  • the disadvantage here is that the fibers collide with the evacuated fiber collection surface and the previously parallel fibers are disoriented again.
  • a method for producing a textile fiber composite in which a fiber mass is separated into individual fibers by means of an opening roller integrated in a housing and the fibers leave the housing through a fiber outlet opening by being detached from the opening roller at a knock-off edge of the fiber outlet opening and into a fiber feed channel enter.
  • the fiber feed channel is oriented toward a fiber collection surface and has an orifice. The fibers are then fed to the circumferential, perforated, vacuumed fiber collection surface, deposited there, compacted and transported away.
  • the mouth of the fiber feed channel is free of negative pressure. Accordingly, no negative pressure is applied to the mouth of the fiber feed channel.
  • the suction of the fiber collecting surface thus does not have such an effect on the fiber feed channel that it makes a significant contribution to the detachment of the fibers from the opening roller.
  • the fibers are detached from the opening roller without vacuum and then reach a fiber guide surface of the fiber feed channel and the suctioned fiber collection surface, where they are stretched and oriented.
  • the fibers form a fiber composite on the fiber collection surface. The stretching of the fibers is maintained or further enhanced on the fiber collection surface.
  • This fiber orientation can be used on the evacuated fiber collection surface to generate a very even compression of the fiber composite. A very uniform and strong yarn is produced from this compacted fiber composite by the subsequent spinning device.
  • an air spinning device for example, an air spinning device, a ring spinning device, a friction spinning device or a pot spinning device can be used as the spinning device.
  • the method according to the invention can thus be used in spinning devices which usually have a drafting system use for feeding the fibers to the actual spinning device.
  • the opening roller is now used with a fiber feed channel on which no negative pressure is applied in order to detach the fibers from the opening roller.
  • the fibers are detached from the opening roller by the centrifugal force acting on the fibers.
  • the fibers are released solely by the centrifugal force generated by the acceleration of the fibers by the opening roller. Since the additional suction forces are absent, the fibers are oriented particularly well in parallel.
  • the fibers are twisted together during and/or after being deposited on the fiber collection surface.
  • This rotation is created by the fiber movement, the movement of the fiber collecting surface and the air flow of the suction of the fiber collecting surface.
  • the fiber collection surface is preferably a screen apron or a screen roller that is moved over a suction channel.
  • the suction channel includes suction openings that can have different shapes.
  • the suction openings can be aligned transversely and, for example, in the form of slots to the transport direction of the fibers. In this case, the fibers lie against the edge of the slit and are compressed.
  • suction openings can then be present in the course of the suction channel in order to maintain the orientation of the fibers and to complete the compression.
  • additional suction openings can be designed, for example, round or transverse to the direction of transport.
  • the stationary suction openings in conjunction with the moving perforated fiber collection surface and the movement of the fibers coming from the fiber feed channel cause the fibers to be twisted and compressed as a fiber composite and delivered to a take-off device, for example a pair of take-off rollers, which transport the fibers away from the fiber collection surface.
  • the fibers are spun into a thread after being transported away from the fiber collection surface.
  • the fibers are twisted with one another in a rotational movement directed along the longitudinal axis of the fiber assembly.
  • the opening roller is arranged in a housing and the housing has a fiber feed port and a fiber exit port.
  • a knock-off edge and a fiber feed channel are arranged at the fiber outlet opening of the opening roller housing, the fiber feed channel being aligned with the fiber collecting surface and having an opening.
  • a fiber guiding surface of the fiber feed channel adjoins the knock-off edge and the fiber collecting surface which is sucked off is arranged following the fiber guiding surface.
  • a cover surface of the fiber feed channel is arranged opposite the fiber guide surface and the ends of the fiber guide surface and the cover surface facing away from the opening roller form the mouth of the fiber feed channel.
  • the end of the cover surface facing away from the opening roller is at a distance from the fiber collection surface, so that the mouth of the fiber feed channel is free of negative pressure.
  • the orifice is therefore not directed directly at the fiber collection surface that is sucked off, so that the suction on the fiber collection surface has no or at least no significant influence on the detachment of the fibers from the opening roller.
  • the end of the top surface of the fiber feed channel is accordingly aligned in such a way that air can flow out of the housing of the opening roller to the environment. As a result, the fibers are largely stretched and fed parallel to one another to the fiber-guiding surface.
  • the fiber guiding surface and the fiber collecting surface form an angle of between +/-30°.
  • the transition from the fiber guiding surface to the fiber collecting surface does not take place in a straight line, but rather at an acute angle. This can improve the straight and parallel handover from the fiber guiding surface to the fiber collecting surface.
  • the fiber guide surface has a kink angle of between +/- 30°.
  • the kink angle forms two sections on the fiber guiding surface, with a first section towards the knock-off edge and a second portion is inclined towards the fiber collection surface. This kink angle can improve the transfer of the fibers from the knock-off edge to the fiber-guiding surface. It supports a rollover of the fibers when they are stopped at the knock-off edge and reach the fiber guide surface.
  • the mouth of the fiber feed channel is delimited by at least one side surface between the fiber guide surface and the top surface.
  • the side surfaces ensure that the fibers detached from the opening roller reach the fiber guiding surface and the fiber collection surface. It has turned out to be advantageous if the two side surfaces run largely parallel to one another.
  • a narrowing of the fiber feed channel to increase the flow speed in the fiber feed channel is thus preferably brought about exclusively by the inclination of the fiber guide surface and the top surface to one another. If there is only one side surface, the transported air can escape laterally, as a result of which the transport and placement of the fibers can be further improved.
  • the fiber outlet opening has a larger cross section than the mouth of the fiber feed channel.
  • the fibers detached from the opening roller are gradually guided onto the fiber-guiding surface with increasing flow speed, even if they are not detached directly at the knock-off edge. The stretching of the fibers and the parallelism of the fibers to one another is maintained or even improved.
  • the distance between the end of the top surface facing away from the opening roller and the fiber collecting surface is more than 3 mm, preferably more than 5 mm.
  • the mouth thus has a height of more than 3 mm. Due to this height of the mouth and the feature that the mouth is not aimed directly at the suctioned fiber collection surface is ensured that the suction of the fiber collection surface does not affect the detachment of the fibers from the opening roller. This prevents the fibers from being compressed.
  • the suctioned fiber collection surface is a sieve apron or a sieve roller.
  • a screen apron can be used to create a fiber collection surface of almost any length. The fibers thus have sufficient opportunity to be calmed down and, if necessary, compressed.
  • the screen roller has the advantage that it takes up less space.
  • the fiber collecting surface which is sucked off has a fiber compacting device, in particular a row of suction slots arranged in a stationary manner.
  • the fibers are compressed at the edge of the suction slot by at least one suction slot positioned at an angle to the transport direction of the fibers.
  • the superimposition of the transport speed of the fiber collection surface, the movement of the fibers emerging from the feed channel and the suction effect of the suction channel imparts a rotation to the fibers and the fiber composite thus produced.
  • the fiber composite deposited on the fiber collecting surface thus forms a kind of roving, with a twist and a smaller cross section.
  • the suction opening, preferably several suction openings, of the suction channel extends obliquely and/or transversely to the direction of rotation of the sieve apron.
  • the suction opening or openings can have a circular, oval, elliptical or rectangular shape.
  • different shapes of the suction openings for example first an inclined suction slit, followed by a sequence of one transverse and two circular suction slits, a very good compression and twisting of the fiber composite can be generated.
  • the suction channel is connected to a suction source.
  • the suction source ensures that the suction channel is sufficiently aspirated to keep the fibers on the fiber collection surface and also to allow the fibers to move transversely to their longitudinal axis in order to allow the fiber assembly to be compressed.
  • the suction must not be so strong that it affects the detachment of the fibers from the opening roller.
  • a dirt separation opening is arranged in the housing of the opening roller between the fiber feed opening and the fiber outlet opening. This achieves a cleaning of the supplied fiber mass from, for example, shell particles and dirt.
  • a spinning device in particular a ring spinning device, an air spinning device, a friction spinning device or a pot spinning device, is arranged downstream of the fiber collection surface.
  • the device according to the invention can be used in all spinning devices which produce a yarn starting from a coherent fiber composite.
  • the fiber detachment does not take place through active suction of the opening roller, but through the attached knock-off edge, including the cover through the fiber feed channel.
  • the fibers are detached by the centrifugal force of the fast-rotating opening roller acting on the fibers, by a back pressure of air caused by the knock-off edge and by which the fibers are detached from the opening roller, as well as by the direct mechanical contact at the knock-off edge, by which the fibers turn over and reach the fiber collection surface.
  • the fiber feed channel is not actively suctioned, as a result of which the fibers are deposited parallel and in a stretched form on the lower surface, namely the fiber collection surface.
  • the fibers are deposited in a particularly advantageous manner for further processing by a yarn-forming device.
  • the fibers are transported through the fiber feed channel by the air flow generated by the opening roller and then reach the zone of the suctioned sieve apron of the fiber collection surface.
  • this vacuumed sieve apron has no influence on the fiber detachment from the opening roller. It serves to tie in the fibers so that the resulting roving is suitable for the subsequent spinning process.
  • the entire production chain can be shortened and there is the possibility of using inferior material for processing. Furthermore, any common spinning process can be used after fiber separation, which guarantees a high level of flexibility and allows cost savings.
  • FIG 1 shows a side view of a device according to the invention with an air spinning device 1.
  • the fibers 2 in a fiber mass 3 for example a so-called draw frame sliver or card sliver, are fed to a faster rotating opening roller 5 by means of a rotating feed roller 4.
  • the opening roller 5 is arranged in an opening roller housing 6 .
  • the fiber mass 3 is introduced into the region of the opening roller 5 by the rotation of the feed roller 4 and the opening roller 5 and the fibers 2 of the fiber mass 3 are separated by teeth which are arranged on the circumference of the opening roller 5 . Dirt particles 7 which are in the fiber mass 3 are separated at a dirt separation opening 8 .
  • the fibers 2 themselves stick to the circumference of the rotating opening roller 5 and are accelerated.
  • the feed roller 4 is arranged at a fiber feed opening 9 of the opening roller housing 6 .
  • the fibers 2 After the fibers 2 have reached a certain speed, they become detached from the rotating opening roller 5 in the area of a fiber outlet opening 10 of the opening roller housing 6 due to the acting centrifugal force.
  • the fibers 2 enter a fiber feed channel 11 and emerge from the fiber feed channel 11 in an opening 12 of the fiber feed channel 11 .
  • the fibers 2 then meet a perforated and air-permeable screen apron 13, which is moved from the mouth 12 to a take-off roller 14.
  • the sieve apron 13 is driven, is deflected by means of deflection rollers 15 and thus leads to a continuous transport of the fibers 2 on the sieve apron 13.
  • the fibers 2 accumulated on the sieve apron 13 to form a fiber composite 29 are removed by means of the take-off roller 14, which is pressed against one of the deflection rollers 15 presses, as a roving 28 deducted from the Sieveriemchen 13 and the air spinning device 1 supplied. There, the fibers 2 are spun into a thread 16 and drawn off from the air spinning device 1 by means of a pair of delivery rollers 17 . The thread 16 is finally wound onto a cross-wound bobbin 18 .
  • Fibers 2 which could not be completely detached from the opening roller 5 in the fiber outlet opening 10 are prevented from further circulation with the opening roller 5 at a knock-off edge 20 .
  • the fibers 2 remain hanging on the knock-off edge 20 and are then laid onto the fiber guide surface 19 and tightened, possibly with a rollover of about 180° in the manner of a somersault. Finally they are released from the opening roller 5 with their residual energy and moved to the sieve belt 13 .
  • a fiber collection surface 23 is provided on the sieve apron 13, on which the fibers 2 come to lie and are transported from the mouth 12 of the fiber feed channel 11 in the direction of the draw-off roller 14.
  • the fibers 2 are ordered, i. H. stored parallel and stretched and, if necessary, also compressed.
  • a suction channel 21 is arranged, which is connected to a suction source, not shown.
  • the sieve apron 13 is designed to be air-permeable, so that the suction channel 21 provided with suction openings generates negative pressure on the surface of the sieve apron 13 according to the indicated arrows and the fibers 2 thus adhere to the surface of the sieve apron 13 .
  • the mouth 12 is designed in such a way that it is not suctioned.
  • the orifice 12 is therefore not in the immediate vicinity and effect of the suction through the suction channel 21.
  • the fibers 2 located in the fiber feed channel 11 are thus detached from the opening roller 5 without the effect of negative pressure.
  • the orifice 12 is therefore sized and positioned so that no vacuum is created on the fiber collection surface 12 is present until it can act into the fiber feed channel 11 . This ensures that the fibers 2 can be detached from the opening roller 5 in a stretched and largely parallel manner and reach the fiber collection surface 20 .
  • the feed channel 11 is designed to converge.
  • a cover surface 22 opposite the fiber guide surface 19 is a cover surface 22 which is inclined in relation to the fiber guide surface 19 and thus reduces the cross section of the fiber feed channel 11 .
  • the opening 12 accordingly has a smaller opening cross section than the fiber outlet opening 10.
  • the fibers 2 are additionally tightened and parallelized by the increased flow rate.
  • FIG figure 2 shows a plan view of the device according to FIG figure 1 .
  • the opening roller housing 6 is shown in section.
  • the opening roller 5 is arranged in the opening roller housing 6 .
  • the opening roller 5 has a sawtooth wire 25 running spirally on the circumference of the opening roller 5 .
  • the sawtooth wire 25 ensures that the fibers 2 are caught and accelerated in the area of the fiber feed opening 9 .
  • the fibers 2 enter the fiber feed channel 11. Fibers 2 that have not yet separated in the fiber feed channel 11 are braked at the knock-off edge 20 and roll over in the area of the fiber guide surface 19. From there they are fed to the moving sieve apron 13 and deposited there.
  • the fiber feed channel 11 has laterally arranged side surfaces 26 which are parallel to one another in the present exemplary embodiment. In other exemplary embodiments, however, they can also converge conically and additionally reduce the cross section of the fiber feed channel 11 . Depending on the embodiment of the invention, one or both side surfaces 26 can also be dispensed with, as a result of which the fiber feed channel 11 is open at the side.
  • Suction slots 27a, 27b and 27c of the suction channel 21 are arranged below the fiber collecting surface 23 of the sieve apron 13 .
  • the suction slit 27a is slit-shaped and designed obliquely to the transport direction of the sieve apron 21, so that the fibers 2 collected at the suction slit 27a are compressed and moved towards the end of the suction slit 27a.
  • the fibers 2, which lie on the sieve apron 13 in the area of the suction slot 27a are laid ever closer together.
  • a row of further suction slots 27b and 27c follows at the end of the suction slot 27a in the transport direction of the sieve apron 13 .
  • the suction slots 27b are rectangular with rounded end faces. You have an elongated extension transverse to the direction of transport. In this way, fibers 2 or fiber ends that are located at the edge of the fiber assembly are caught and further compressed in the following.
  • Two round suction slots 27c are arranged between the elongated suction slots 27b. The fibers 2 are held close together with these round suction slots 27c, so that they form a roving 28 in the area of the draw-off roller 14.
  • the roving 28 has a slight twist and can finally enter the air spinning device 1 and is spun into a thread 16 there.

  • FIG 3 a side view of the device according to the invention in the area of the fiber feed channel 11 is shown in section. It can be seen from this that the top surface 22 is designed to be inclined in relation to the fiber guide surface 19 . As a result, the cross section of the fiber feed channel 11 is reduced from the fiber outlet opening 10 to the mouth 12 .
