Definitions

  • the invention relates to a spinning device for producing a spun thread from a fiber structure, comprising a nozzle block with a fiber conveying channel, with a fiber feed surface for guiding the fibers and with a nozzle part with a or several nozzles that blow the fiber assembly with a rotating air stream and a rotating or stationary hollow spindle with a Entry opening to a yarn channel for receiving from the fiber feed surface supplied fibers and for guiding the spun thread.
  • the fibers are either drawn from a drafting system or from a suction drum against the fiber feed channel and in this in the Entrance mouth of a rotating or stationary hollow spindle guided, the front ends of such fibers in the fiber structure and in the entrance mouth, or in the yarn channel, while the rear free ends spread and captured by the rotating air flow and around which is already in the Entrance mouth, or located in the yarn channel, i.e. integrated front ends are twisted around to create a real twist yarn, similar to a ring spun yarn, it being noted that the term "front" and "rear" ends of the fibers related to the direction of conveyance of the Fiber was chosen.
  • the disadvantage of this process is the complex process steps and the complex device, which the elements in the axial direction of Must separate the spinning process and bring auxiliary elements in between ultimately to bring the end of the yarn to the place where it is to be attached with the supplied fibers.
  • This usually leads to such devices are arranged vertically, that is, the drafting system in front of the spinning device Sliver takes over from a standing jug underneath and usually delivers the knitted fiber structure in the vertical direction of the spinning unit.
  • This Arrangement is the most appropriate because of the operation of the spinning unit, since that This gives operators a good overview of the spinning process and one receives good access for the operation of the spinning elements.
  • the winding unit in the sequel is designed so that it can be used by can be operated on the same side of the machine. If, as previously mentioned, the Elements of the entire unit must be moved apart in the spinning direction, to guide tools in between so that piecing can be carried out so this pulling apart leads to an uncomfortable, long, that is, high and unfavorable for the operator.
  • the object is achieved in that at least the fiber feed channel can be divided in this way and to open it is that the fiber guide surface is open and accessible.
  • the nozzle part can also be divided and opened in such a way that it is open and is accessible. Furthermore, it is also advantageous, also the spindle to make it divisible accordingly so that the yarn channel is open and accessible.
  • the advantage of the invention is that all three elements mentioned, without the axial disassembly of the entire spinning unit, in a direction perpendicular to the spinning direction can be opened, so that also the accessibility to the critical point between the entry mouth of the spindle and the exit point of the Yarn guide channel is optimally enabled.
  • Fig. 1 shows a drafting system 1 with input rollers 21, middle rollers 20 with straps 20.1, which fibers transport against a pair of delivery rollers 2, which in turn the Deliver fibers further into a fiber feed channel 16.
  • the delivery rollers 2 exist on the one hand from an upper delivery roller 18 and a lower delivery roller 19.
  • the fiber-processing spinning unit (S) then includes the delivery rollers 2 a fiber conveying part 3, consisting of an upper fiber conveying part 4 and one lower fiber conveyor part 5. This is followed by a nozzle part 6 with blowing nozzles 17, which are arranged in a manner known per se such that, on the one hand, on the basis of a Air injector effect is sucked through the fiber feed channel 16 and on the other hand in in a known manner, this air as a vortex flow free, preferably rear Ends of the supplied fibers and around which is already in the mouth part 26 a yarn guide channel 12, i.e. wrapped front ends twisted around and twisted into a yarn.
  • a mandrel 23 extends close to or even in the mouth part 26, thereby a relatively narrow passage space for the fibers to be brought into the mouth 26 arises, which can lead to malfunctions if dirt, for example, fractions of cotton seeds to be clamped in between so that there is an immediate interruption in spinning and yarn.
  • the spindle 25 must be in the axial direction Retracted toward the space between the mouth 26 and the To clean mandrel 23, and it must, as mentioned at the beginning, also a suction element on the Mouth 26 are set to take back the yarn end to this to bring to or through the fiber guide channel 16.
  • At least the fiber conveying part 3 is designed to be divisible by the upper fiber conveyor part 4 together with an associated channel part 22 in the direction of arrow C. can be lifted or pivoted away, so that the fiber feed channel 16 is free and the area in front of the mouth 26 is accessible.
  • the lower one remains Fiber conveyor part 5 together with the mandrel part 24 stationary.
  • the nozzle part 6 with everything that is dash-dotted and include lines united in arrow B, that is also including the line Lifting or swiveling nozzles 17 in order to thereby provide even more space for the To create cleaning.
  • the lower nozzle part 8 and the nozzle shown therein remain 17 stationary.
  • a still further variant consists in the yarn guide part 9 together with an upper part 13 of the spindle 12 and an upper yarn guide part 10 in the direction of arrow A. lift or swivel after the nozzle part G in direction B was lifted or pivoted, so that the yarn guide channel 12 to Cleaning is free. This leaves a lower yarn guide part 11 together with a lower part 14 of the spindle 25 stationary.
  • the advantage of opening the above three elements not only brings the advantage of Cleaning, but also the advantage of simply bringing back a yarn end, which are inserted on the one hand in the lower part 14 and in the open fiber conveying channel 16 to even end this end manually between the entrance of the fiber feed channel 16 and bring the delivery rollers 2.
  • Another possibility is to move the upper delivery roller 18 in the direction of arrow C.1 also to be lifted or swiveled around the aforementioned yarn end even further over the lower feed roller to thereby advance this yarn end as shown to combine the pair of delivery rollers 2 with newly fed fibers.
  • FIG. 1 shows how mentions a variant of the device of Fig.1 by instead a delivery roller pair 2, the upper delivery roller 18 with a suction roller 27 with a Suction air connection 29 cooperates to fibers in the nip between them pull both rollers out of the strappy pair and in area 30 on the Suction roller by means of the rotation of the suction roller and the suction effect against the To deliver fiber feed channel 16 and by means of the blowing air 31, then to the in Suction segment 28 located suction area 30 to blow into the fiber feed channel 16 and thereby the aforementioned, generated by the injector action of the nozzles 17 To support transport air.
  • FIG. 5 shows the same units, which are included with the letters A and B, while section C of FIG. 1 in FIG. 5 has a variant in that instead of the lower delivery roller, a suction roller 27 is provided, which with the upper Delivery roller 18 cooperates and forms a nip. After this nip the fibers on the suction roll 27 in the suction area 30 on the surface of the Suction roller held and at the end of this suction area 30 by a blowing air stream 31 blown against the fiber feed channel 16, in which the aforementioned air flow Fibers 34 takes over and promotes through the fiber feed channel 16.
  • a pressure roller 35 by means of pressure springs 36 resiliently mounted so that the fibers on the surface of the Suction roller can be pressed with the force of the springs, thereby a more stable To achieve fiber delivery in the fiber feed channel 16 than without this pressure roller 35th
  • the pressure roller 35 is spring-mounted in a roller bearing part 37, as mentioned, wherein the roller bearing part 37 is fixedly connected to a channel part 22.
  • Elements can be used to lift or swivel group E elements be to expose the fiber feed channel 16, for example, one of the Spindle 12 coming yarn end to be transferred to the suction roll 27.
  • blowing nozzles 17 are provided.
  • blowing nozzles 17 By means of these blowing nozzles 17, of which two more can be provided, one is in the generates the aforementioned vortex already described, by means of which free rear fiber ends are wound around front fiber ends to thereby to produce a yarn that does not pass through the yarn guide channel 12 from here drawn-off rollers shown is withdrawn.
  • the fibers which are from the left, with a view of the picture seen, brought to a fiber guide surface 41, by means of a Injector action of the nozzles 17 generated suction air flow on the fiber guide surface 41 brought against an inlet mouth 26 of the spindle 25 to, as mentioned, the To produce yarn.
  • a lower part 14 of the spindle 25 is in turn with a lower yarn guide part 11 connected, which remains stationary.
  • the upper part 13 and the lower part 14 are separated at the separating surface 15 the spindle 25. Furthermore, the lower nozzle part 8 is also stationary Support part 42 firmly connected, so that the fiber guide surface 41 is also stationary is.
  • Fig. 6.1 shows that the spindle 25 in the area of the inlet mouth 26 with a wear-resistant ring 22 is provided.
  • This ring 22 is because the spindle 25 like described with FIGS. 8 and 9 is opened, with the stationary part 14 or movable part 13 connected, so that still for said cleaning, or piecing, there is enough freedom.
  • this ring according to FIG. 9 also in one upper connected to the upper part 13 and in a lower to the lower part 14 share connected part.
  • the separation channels 39 can also each in a ring half are provided with the same advantage as described for FIG. 9.
  • Fig. 7 shows a cross section corresponding to the section lines III-III (Fig. 6), in which shows a separating surface 48, of which the upper nozzle part in the direction F or F.1 is lifted off.
  • channels 40 are embedded in order to clamp edge fibers on the Avoid the interface.
  • Fig. 8 shows a section through the spindle 25 according to the section lines IV-IV with the separating surface 15, which coincides with the center line of the spindle.
  • FIG. 7.1 shows a variant of FIG. 7 in that the fiber conveying channel is not by means of a flat separating surface 38 (FIG. 7), but by means of a channel-shaped, lower nozzle part 8.1 and a matching, segment-shaped, upper Nozzle part 7.1.
  • This type of separation of the two parts has the advantage that the separation channels 40, as shown in Fig. 7, can be dispensed with, since the separation of the segment-shaped, upper nozzle part 7.1 is located much higher than that Separation surface 38 in FIG. 7. This means that there is even less risk of fibrils captured in the separation area can be captured than with the separation channels 40 of FIG. 7th
  • Fig. 8.1 The same principle is applied in Fig. 8.1, in that the interface is not a plane is like the separating surface 15 of FIG. 8, but is also provided in the form of a channel, in which the upper part 13.1 is provided in the form of a segment and corresponding to channel-shaped lower part 14.1 fits in the sense of a sealing surface.
  • segment-shaped upper part 13.1 is lifted up in the same way becomes like the upper part 13 of FIG. 8.
