Definitions

  • the invention relates to a sliver compressor in drafting systems of spinning machines, the drafting system being one of a pair of straps and a roller pair arranged after this Stretching field and a support and load arm and where the fuse compressor oscillates on one of the carrying and loading arms supported bearing rod is stored and its compression funnel in the gusset at the inlet of the downstream pair of rollers lies.
  • Such a sliver compressor is, for example, from DE 1.825.759 U known.
  • the two, in their interaction, the compression funnel forming elements of the same are each over a web each connected to a bearing bush on the bearing rod is pivotable. So that the compression funnel suits the respective follow the path of the generally changing fuse can, is the bearing rod itself or are bearing sleeves on which the bearing bushes can pivot, but not axially are, to a certain extent, also axially displaceable on the bearing rod.
  • the connecting the compression funnels and their bearing bushes Webs extend between the top strap and the peripheral surface the top roller of the strappy pair upwards. Between this Upper apron and this top roller must therefore be a distance for the passage of the webs may be provided. However, this has the Disadvantage that the distance between the outlet of the pair of straps and the clamping line of the downstream roller pair accordingly must be enlarged. This will lead the Fibers in what is usually the main warping field The drafting field of the drafting system is reduced and thus the quality of the yarn produced is impaired.
  • the object of the invention was accordingly the compression funnel of a fuse compressor in the draw field of a To keep the drafting system so that the distance does not increase between the outlet of the strappy pair and the clamping line of the downstream roller pair is required.
  • the compression funnels of the preferred type of the sliver compressors mentioned at the outset consist of two parts which are held in an oscillating manner and which, in cooperation, form the sliver funnel. In some cases, the compression funnels are also made in one piece. In the former case, each section of a compaction funnel has a holding arm, which then engages around the top apron and / or the top roller of the downstream roller pair on the side on which the section of the compaction funnel is arranged with respect to the fuse to be compressed.
  • the top strap and / or the top roller of the downstream pair of rollers lateral support arm required.
  • the holding arm is the rule for the use of top roller twins and twin straps advantageously the free side of these twin organs. Then there is right-hand gripping and left-hand gripping arms.
  • a further embodiment of the invention is in one piece Compression funnels with one or two funnel openings, at which the top of the funnel opening is closed and only has a threading slit for the fiber sliver at the bottom, provided that the compression funnel on its top in a thin partition merges into the space in between extends between the top apron and the top output roller.
  • This partition prevents the fiber sliver from reaching the top edge of the funnel exceeds and bypassing the compaction funnel runs to the pair of output rollers. This danger can be seen at two-parted funnel not given.
  • the drafting system has three pairs of rollers 1, 2 and 3 along the length of the drafting unit, driven lower rollers 4 and Twin top rollers 5.
  • the lower roller 4 of the pair of output rollers 3 is immediate, the lower rolls of the other pairs of rolls 1 and 2 are stored in punch 8 via bearing carriages 6 and 7, respectively.
  • On the punches 8 are also carrying a support rod 9 and load arms 10 hinged, which the here Management and stress organs of the Top rollers 5 of the roller pairs 1 to 3 contain.
  • compression funnels 14 are in the inlet side Gusset between the rollers 4 and 5 of the pair of output rollers 3 on the rollers.
  • the compression funnels 14 are each means at least one holding arm 15 and a bearing bush 16 a handrail parallel to the rollers of the drafting system 17 oscillating.
  • the apron units serve to bring the fibers in the draft zone as close as possible to the clamping line of the downstream pair of rollers 3.
  • this holding arm is shown laterally next to the Let the upper roller 5 and / or, as not shown in detail, run laterally next to the top strap 12.
  • the holding arms 15 are of an angular design for this purpose.
  • sliver guides 2 consist of their compression funnels 14 two funnel elements, each swinging independently 18 and 19 interacting with the compression hopper form.
  • Each of these funnel elements 18, 19 is over a holding arm 15 and 15 'and a bearing bush 16, 16' on the Bearing rod 17 stored.
  • Clamping discs 20 limit the axial Movability of the sleeves 16, 16 'on the bearing rod 17.
  • everyone Holding arm 15, 15 ' consists of a first, parallel to the rollers, in the gusset of the pair of output rollers 3 lying web 21 and a web with the associated bearing bush 16, 16 'connecting second web 22, the side according to the invention is next to the top roller 5 or the top strap 12.
  • these webs 22 can just as well be straight or also be curved in the opposite direction, which makes them next to the top strap 12 come to rest.
  • the compression funnels are 14 formed in one piece and open at the bottom. In this case One arm is sufficient to hold a compression funnel 15, which is otherwise designed according to Figure 2 can be.
  • Fig. 5 shows an embodiment of the one according to the invention Compression funnel in a drafting system for manufacturing of core yarn.
  • Core yarn means a yarn in which a supplied, finished core thread - usually a synthetic one Continuous thread - is wound with fibers.
  • the core thread is the fiber sliver stretched in the drafting system in front of the pair of exit rollers fed.
  • the one-piece fuse compressors 13 each two holding arms 15, 15 'on the on the Holding rod 17 slidably guided bushings 16, 16 'formed are. Between the bearing bushes 16, 16 'is a grooved roller 25 rotatably mounted on the support rod 17.
  • the compression funnels 14 of the two sliver funnels 13 through the fiber sliver in the latter issued oscillation over part of the width of the corrugated Area of the lower roller 4 entrained.
  • the grooved roller 25 is also taken along, so that the incoming Core thread is always guided on the fiber sliver.
  • the holding arm 15 is one of the two sliver compressors 13 also against the inside of the twin top roller the loading arm 10 can be arranged when the Space allow this. It is then the arm of the a compression funnel 14 on the outside, that of the other Compaction funnel on the inside of a twin top roller 5.
  • This embodiment has the advantage that the sub-compressor 13 can be executed the same.
  • Fig. 4 shows an embodiment of the held according to the invention Compression funnel in a drafting device for spinning.
  • Spinning threads is understood to be a spinning process in which two fiber lunches in parallel next to each other through a job of a drafting system run and at the exit of the drafting system under the effect of the rotation given by the spindle be combined into one yarn.
  • the yarn produced in this way is like a thread and is therefore also known as a false thread.
  • the fuse compressor 13 in the embodiment of the Fig. 4 two compression funnels 14 and 14 ', in each one of the two fibers is guided and compressed becomes. Because the determined by the intake funnel of the drafting system mutual distance between the two fiber lunches equal remains, the two compression funnels 14, 14 'with the mutual distance predetermined by the inlet funnel be arranged a common compression body.
  • FIG. 4 is a further embodiment of the sliver compressor according to the invention. He points in between the top apron 12 and the top output roller 5 lying area a thin, possibly only film-like Partition 24 on the top of the compaction funnel 14 is formed. You can also use the holding arm 15 and the bearing bush 16 and thereby increases - if it is stiff itself - the stiffness of the fuse compressor 13th
  • this partition 24 By means of this partition 24 it is prevented that fibers over the Upper edge of the two compression hoppers 14 and 14 'containing one-piece compression body and thus on the compression funnel pass.
  • This thin partition 24 has only the task of bypassing the compression funnels 14, 14 ' prevent the compression hopper from being held too this embodiment solely by the side of the top strap 12 and laterally the upper roller 5 lying arm 15 reached.
  • partition 24 is also readily available the embodiments having an integral compression funnel 14 the invention according to Figures 3 and 5 can be used is.
