Definitions

  • the invention relates to an interchangeable reinforcement for a suction channel Fiber bundling device of a spinning machine, with at least one for guiding one air-permeable transport element for a fiber structure suitable sliding surface, with at least one in the sliding surface, enclosed on all sides like a window Suction slot and with contact surfaces for attaching to corresponding counter surfaces Basic body of the suction channel.
  • a stretched fiber structure is immediately adjacent to the draft zone of a A spinning twist is given to the drafting system, then arises at the clamping line of the Output roller pair a so-called spinning triangle.
  • the spinning triangle contains edge fibers that are not properly tied into the twisted thread and therefore little or nothing Contribute to the strength of the spun thread.
  • One has therefore recently started to to assign a so-called compression zone to the draft zone of a drafting system is in turn bounded on the outlet side by a clamping point. Only then will the thread become the Spinning rotation granted.
  • the fibers are bundled or compressed in the compression zone, whereby the fiber structure is so narrow when leaving the last nip that the dreaded spinner triangle no longer arises.
  • the spun thread then becomes more even, firmer and less hairy.
  • the compression zones mentioned usually have a suction channel, with the help of which the compression zones each generate a suction air flow that compresses the Fiber association causes or supports.
  • Such suction channels are often with a interchangeable reinforcement.
  • a reinforcement for a suction channel of the type mentioned at the outset is provided by DE 199 22 861 A1 State of the art.
  • the known reinforcement extends only over the area of one of the Compression zone associated suction slot, which it surrounds on all sides like a window.
  • the Known reinforcement is placed on a base body in the area of the suction slot is in turn provided with at least one suction slit.
  • the suction slot of the suction channel thus extends both through the reinforcement and through the base body. Since the Base body usually consist of metal, into which the suction slots are milled, the basic bodies have to be deburred at each suction slot in a time-consuming manner. Moreover the individual reinforcements in corresponding recesses of the base body in Area of each suction slit to be inserted exactly.
  • the invention is based on the object, the reinforcement is less complex and less tolerant to design and to dispense with time-consuming deburring processes.
  • the object is achieved in that the reinforcement as a the base body to the suction channel complementary component is formed.
  • the basic body which is designed as an open basic profile, is therefore only closed by the reinforcement a closed suction channel, except of course the individual suction slots and an in Base body attached vacuum connection.
  • the existing body and reinforcement Suction channel preferably extends over several, for example eight, spinning stations or one Machine section. Because the reinforcement is no longer an insert in the surface of the base body must be inserted, but only with itself in the longitudinal direction of the suction channel corresponding contact surfaces on mating surfaces of the base body are unnecessary unnecessary tolerances that would make the product more expensive. Since the suction slots are only in the If the reinforcement is located, the base body can have one on its side facing the reinforcement have continuous longitudinal opening, so that any deburring on the usually a metal body can be omitted.
  • the reinforcement is advantageously designed as an injection-molded plastic part and thus as a so-called Suction slot bar designed.
  • the sliding surface of the reinforcement is so long that it is assigned to a drafting system Includes deflection guide.
  • Drafting units usually have a pair of output rollers, in whose output wedge gap projects into the suction channel with a deflection guide that is right has a small radius. Due to the small radius, the deflection guide is also wear-prone, so that it is an advantageous component of the reinforcement.
  • the transport element not only slides over the sliding surface of the reinforcement, but also over it some outer contours of the base body, but only on those outer contours where Experience has shown that practically no wear occurs. So that the operation of the revolving transport element is possible, is in a further embodiment of the invention provided that the sliding surface of the reinforcement at its circumferential ends into the Outer contour of the base body merges. So there is neither in the reinforcement nor in the Protrusions disrupting the circulation of the transport element.
  • the reinforcement 1 shown in FIGS. 1 to 3 for a suction channel 2 belongs to one Fiber bundling device 3 and is part of a spinning machine, preferably one Ring spinning machine.
  • This spinning machine has only one part in FIG. 1 for each spinning station Draw frame 4 shown, of which only one pair of output rollers 5 and one previous pair of straps 6.7 is shown.
  • the output roller pair 5 contains a continuous, in the machine longitudinal direction, Driven lower cylinder formed lower roller 8, one printing roller 9 per spinning station assigned.
  • the lower roller 8 and the pressure roller 9 together form one Exit clamping line 10, which ends the draft zone of the drafting device 4.
  • a fiber sliver or roving 11 is fed to the drafting device 4 in the transport direction A and warped in drafting device 4 in a known manner to the desired fineness.
  • the Output roller pair 5 of the drafting system 4 follows a compression zone 12 in which the stretched but still spinning twist-free fiber structure 13 can be bundled or compacted should.
  • the existing fiber bundling device 3 contains a transport element Air-permeable conveyor belt 14 which passes the fiber structure 13 through the compression zone 12 transported.
  • the conveyor belt 14 is advantageously made of a thin, fine-mesh fabric belt Plastic threads trained.
  • the invention also as Includes suction elements designed transport elements, such as those in DE 198 19 019 A1 are described.
  • the outlet end of the compression zone 12 is defined by a clamping point 15 which also serves as a swirl barrier, so that the fiber structure 13 in the compression zone 12 remains rotation-free.
  • the thread 16, which is in Delivery direction B is fed to a swirl element, not shown, for example an annular spindle and gets its spin.
  • the fiber bundling device 3 also contains the already mentioned suction channel 2, which consists of a profiled base body 17 and the aforementioned reinforcement 1 is formed.
  • the suction channel 2 preferably extends over a plurality of, for example, eight spinning positions and is over a vacuum connection 18 connected to a vacuum source, not shown, so that the suction channel 2 is under vacuum overall.
  • the outside of the suction channel 2 facing the conveyor belt 14 carries the one sliding over it Conveyor belt 14.
  • a clamping roller 20 is used to effect the required swirl stop at the clamping point 15 provided that drives the conveyor belt 14 and the fiber structure 13 to the conveyor belt 14 and at the same time the conveyor belt 14 with a certain pressure against the suction channel 2 suppressed.
  • the pinch roller 20 in turn receives its drive via a toothed belt 21 from the Printing roller 9 of the drafting device 4.
  • the reinforcement 1 is provided which is described in more detail below. It is designed to be lock-resistant, for example as an injection molded plastic part, but nevertheless a wear part that can be replaced from time to time.
  • the length of the reinforcement 1 corresponds to the length of the base body 17.
  • the latter is an above open profile, with a continuous upper opening 22.
  • the open profile of the base body 17 is supplemented by the reinforcement 1 to the all-round closed suction channel 2, except in the reinforcement 1 attached suction slots 19 and those in the base body 17 Vacuum connection 18.
  • the outside of the suction channel 2 that guides the conveyor belt 14 consists of a sliding surface 23 formed by the reinforcement 1, which contains the suction slots 19, and a smooth transition at the circumferential ends 24 and 25 of the reinforcement 1 Outer contour 26 of the base body 17.
  • the respective conveyor belt 14 leaves the Outer contour 26 of the base body 17 and is guided there by a clamping device 27.
  • the reinforcement 1 has contact surfaces 28, 29 with which it can be connected to corresponding counter surfaces of the Base body 17 is attached.
  • the reinforcement 1 is in its entire length Base body 17 clipped in and therefore easily replaceable.
  • the sliding surface 23 of the reinforcement 1 closes a deflection guide 30 provided with a narrow radius 1, which projects into the wedge gap of the pair of output rollers 5.
