Definitions

  • the invention relates to an opening roller unit Open-end spinning unit according to the preamble of claim 1.
  • Opening roller units of open-end spinning units that are used for Dissolving fed slivers have been used since Proven in practice for many years.
  • an opening roller the sawtooth through one wound on the roller body of the opening roller Sawtooth wire is formed.
  • the sawtooth wire can open the cylindrical surface of the opening roller be wound or be inserted in a helical groove.
  • the End areas of the sawtooth wire usually do not have any Teeth. They are used to set the sawtooth wire on the Roll body, for example by the ends in a Indentation of the helical groove.
  • DE 31 23 480 C2 shows an opening roller unit which essentially consists of a base body and a ring, wherein the ring is rotatably connected to the base body.
  • On the outer peripheral surface of the ring is a helical sawtooth wire introduced into the circumferential groove.
  • the ring can be needles inserted in bores.
  • the ring of the The opening roller is coiled on the side Saw tooth set arranged ring bundles. Thereby, that the ring is detachable from the base body, it is possible the area between the bearing housing and the opening roller relatively easy without complex disassembly Clean the opening roller unit.
  • DE 44 11 735 A1 also discloses an opening roller Open-end spinning unit, which has a main body and a ring-shaped clothing carrier with integrated ring bundles includes.
  • the training is intended to be easy to assemble and Disassembly, for example during maintenance, as well as a allow uncomplicated cleaning of the opening roller unit.
  • the set attached to the set carrier consists of Sawtooth wire wound on the outer circumference or from in Rows of helical needles arranged in bores are indented.
  • the clothing is in the edge region the sawtooth wire is not pulled up to the coils or where it is drawn close to the coils he no more teeth, as is the figure 2 of DE 29 04 841 A1 can be seen and what is consequently in Edge area of the saw tooth set affects. Total results between the clothing area where teeth are present are, and the edge disc a space in which no teeth is present. The width of this free space can be larger than that in the clothing area over the working width Distance between the rows of teeth. The distance between the Row of teeth is called tooth alley. Such freedom is for example in the respective figure 1 of DE 29 04 841 A1 or DE 31 23 480 C2 clearly recognizable.
  • teeth are in the peripheral surface of the sleeve at least one substantially in the circumferential direction helical circumferential groove and several essentially in Incisions made in the axial direction are incorporated.
  • a surface treatment process such as Subjected to hardening.
  • the opening roller can be fed in areas where there is no Material feed and therefore no seal against the Outside air takes place through the tooth lanes due to air in the
  • the prevailing rotor housing of the open-end spinning unit Negative pressure with respect to the peripheral speed of the Opening roller sucked in increased flow rate become. In principle, this can affect the entire working range any places occur where insufficient Fiber material is fed. Such an inadequate Feeding the fiber material is largely on the Border area limited.
  • the suction effect is present of the free spaces in the edge area described above strong. Due to the increased air flow, the edge is still not or only insufficiently dissolved fiber material the open spaces sucked in and carried along. fiber material can thus get into the spinning rotor undissolved and there Cause disruption of the yarn manufacturing process. For example, the yarn leaving the spinning rotor have unwanted imperfections in the form of thick spots.
  • Opening roller unit which is simple and quick Assembly and disassembly allowed.
  • the number of to produce and components of the opening roller unit to be assembled minimized.
  • the grooves run across the Cross-cuts at such a distance of the end face that a ring collar remains. So that will uncontrolled suction of undissolved fiber material prevented and the risk of malfunctions or yarn errors in the Yarn manufacturing process reduced.
  • Adequate protection The teeth are given when the diameter of the ring collar is at least so large that the tips of the teeth do not form the collar overtop. Since with the completion of the teeth also Ring collar is present, the teeth are so from the start and constantly protected from damage.
  • the manufacture of the opening roller ring is thereby simplified that the teeth in the edge area of the sawtooth set are not fully formed.
  • the invention No further shaping of the teeth for Edge of the sawtooth set does not get unwanted Impairment of the process of dissolving the fiber material out. Open spaces, - through which insufficiently resolved Fiber material can be sucked in and carried, and the associated disadvantages are avoided.
  • the opening roller ring according to the invention reduces the Manufacturing and assembly costs and improves the Yarn manufacturing process and contributes to an increase in Profitability of open-end spinning units.
  • the open-end spinning unit 1 shown in Figure 1 includes a rotor housing 2 in which a spinning rotor 3 at high speed circulates.
  • the spinning rotor 3 is with its rotor shaft 4 supported in the gusset of a support disc bearing 5.
  • the spinning rotor 3 is driven by a machine-long tangential belt 6, which by a Pressure roller 7 is turned on the rotor shaft 4.
  • the Tangential belt 6 is not shown reversible and frequency controlled electric motor applied.
  • the rotor housing 2 is during the Spinning operation by a pivotably mounted cover element 8 locked.
  • the cover element 8 has a for this purpose Channel plate 12 with a seal 9.
  • the rotor housing 2 is also via a corresponding suction line 10 to a Vacuum source 11 connected to the in the rotor housing 2nd necessary spinning vacuum generated.
  • a Channel plate adapter arranged, the thread take-off nozzle 13th and the mouth region 25 of the fiber guide channel 14.
  • the thread draw-off nozzle 13 is included Thread take-off tube 15.
  • an opening roller housing 17 is set on the cover element 8, which is pivotally supported to a limited extent about a pivot axis 16, an opening roller housing 17 is set.
  • the cover element 8 has rear bearing brackets 19, 20 for storing one Opening roller 21 or one Sliver feed cylinder 22.
  • the opening roller 21 is in the Area of their whorl 23 by a revolving machine-long tangential belt 18 driven during the Not shown drive of the sliver feed cylinder 22nd preferably via a worm gear arrangement. Further details of such open-end spinning units are for example DE 198 41 401 A1 or its parallel U.S. Patent No. 6,105,355 removable.
  • the opening roller 21 carries a set of teeth and rotates with it high speed.
  • a sliver 24 is fed through it the teeth gripped and taken away and in this way in Individual fibers is dissolved.
  • the individual fibers taken along detach from the teeth of the opening roller 21 and become due to the negative pressure prevailing in the rotor housing 2 the mouth region 25 of the fiber guide channel 14 in the Rotor cup 26 transported.
  • the rotor cup 26 forms the yarn that is produced by the Thread take-off nozzle 13 and the thread take-off tube 15 are drawn off becomes.
  • the opening roller ring 27 shown in Figure 2 has together with the ring bundles 32, 33, which are part of the Opening roller ring 27 are.
  • Such opening roller rings can be catchy or multi-course.
  • the opening roller ring 27 double-start that is, it run two grooves side by side.
  • a difference of the opening roller ring 27 according to the invention compared to known opening roller rings, the teeth of which are machined out of a sleeve, is that the grooves 30 are not continuous to the head end of the set with full groove depth T N , but at a distance from the head end that is the width the bundle of rings corresponds to 32.33.
  • This forms a transition region 29 on the annular collar 33 in which, as can be seen in FIGS. 2 and 3, the depth of the groove 30 increases in the direction of the arrow 31 until the full groove depth T N is reached.
  • the depth of the groove 30 on the annular collar 33 slowly decreases in a transition region and the grooves 30 end at a distance from the head end which corresponds to the width of the annular collars 32, 33.
  • Figure 3 shows the opening roller ring 27 of Figure 2 in one Manufacturing phase.
  • a grinding wheel 28 for insertion the circumferential grooves are indicated by dashed lines.
  • the grooves 30 and also across the webs 34 or the grooves 30 extending grooves run at such a distance from the head end that at the Edges of the opening roller ring 27 as the material of the sleeve Ring collar 32, 33 remains.
  • the outside diameter of the Collars 32, 33 is so large that the tips of the teeth Ring collar 32, 33 do not protrude, but with the surface on The outer diameter of the coils 32, 33 lie at one level.
  • From the webs 34 remaining between the grooves 30 are the Teeth 36 shaped.
  • the incisions 35 form together with the helically circumferential grooves 30, the teeth 36 with the Chest surfaces 37 and the back surfaces 38.
  • the incisions 35 are by means of a Introduced grinding wheel.
  • the lines 39 that run the course or indicate the direction of the incisions 35, form in the embodiment of Figure 2 with the axis 40 of Opening roller ring 27 has an acute apex angle ⁇ . This allows a more extensive formation of the tooth shape nearby the collar 32, 33 when using disc-shaped tools for the production of the opening roller ring 27.
  • the tips of the teeth 36 have one through chest surfaces 37 and back surfaces 38 formed apex angle a of at most 30 degrees.
  • the shape of the teeth 36 thus formed allows a particularly effective and even dissolution process of the supplied sliver 24.
  • the opening roller unit in the frame is possible.
