Definitions

  • the invention relates to a circular comb for attachment to a shaft of a combing machine which is rotatable about an axis of rotation in a combing direction and which is intended for combing textile fibers and has fixed take-off rollers for the combed textile fibers.
  • Combs for use in combers are e.g. known in the form of circular or circular combs by prior public use, wherein comb elements are arranged on a circular comb base body, which are in engagement with the beard of the textile fibers to be combed.
  • a comb which is provided with combing elements along at least part of its circumference is referred to as a circular comb.
  • the active combing area can be, for example, 78 °, 90 °, 111 °, 137 ° or 180 ° of the circumference of a surface line of the circular ridge.
  • the combing elements can e.g. are needles, pinstripes, sawtooth wire sections, comb teeth or in particular sawtooth stampings.
  • combing bars which are sometimes also referred to as combing sets.
  • Such a combing bar can e.g. several axially, i.e. in the direction of the axis of rotation, saw tooth punched parts arranged one behind the other, saw tooth wire sections or toothed disks provided with teeth.
  • a combing machine comprising a circular comb, in which both the proportion of newly combed fibers supplied by the pliers unit and the proportion of previously combed fibers held by the take-off rollers are to be kept in their respective correct positions before and during the soldering process.
  • a fringe control element is provided, which, viewed in the combing direction, is arranged behind an actual comb segment of the circular comb.
  • the fringe control member has a free space behind the comb segment, which serves to maintain an air flow directed past the lower take-off roller and downward in the direction of a suction box, so that the part of the backward movement carried out by the take-off rollers in the course of their mit step movement is transported back towards the circular comb Combed fibers (in the previous combing cycle) are pressed onto the lower take-off roller.
  • the fringe control element has a tip line surface on which the proportion of newly combed fibers supplied by the pliers unit rests in order to prevent kinking.
  • EP 3 034 660 A1 describes a circular comb with an air guiding or guiding element arranged behind the combing segment of the circular comb when viewed in the combing direction.
  • This guide element is intended to control the air flow in such a way that the part of the (combed out) fibers that have been combed back by the take-off rollers lies against the lower take-off roller.
  • the object of the invention is therefore to provide a circular comb of the type mentioned at the outset with improved properties compared to the previously known embodiments.
  • the circular comb according to the invention has a circular comb base unit with an outside, a comb segment with a plurality of combing bars arranged on the outside of the circular comb base unit, which are equipped with outwardly projecting comb teeth, the front comb tooth flanks of which are inclined in the combing direction, as viewed in the combing direction, and on Alignment segment arranged on the outside of the circular comb base body unit, which is equipped with a plurality of outwardly projecting alignment elements, the front alignment element flanks of which, when viewed in the combing direction, are each inclined against the combing direction, and a part of which, when viewed in the combing direction, is arranged at least substantially one behind the other.
  • the alignment elements can be, for example, alignment teeth, alignment needles or similar elements.
  • the alignment teeth can in particular have different tooth geometries and can preferably be integral components of sawtooth punch strips, of sawtooth wire sections or of toothed disks.
  • the aligning elements like the combing teeth, consist in particular of a metal material and are preferably mechanically rigid.
  • these alignment elements each have front alignment element flanks which are each inclined against the combing direction, that is to say in particular have a negative element face or tooth face angle.
  • the comb teeth of the comb bars of the comb segment differ from the comb teeth of the comb bars of the comb segment.
  • the latter also project in particular essentially radially outwards.
  • they have front combing tooth flanks, which are each inclined in the combing direction, that is to say have a positive tooth face angle.
  • This positive tooth face angle can also be referred to as the tooth engagement angle.
  • the combing engagement of the combing teeth in the area of the combing segment results in the textile fibers held and still to be combed, in particular by the pliers unit.
  • the combing teeth of the combing bars cover a combing circumferential angle area and in their entirety form the actual combing area of the circular comb.
  • such a meshing intervention should not take place through the alignment elements. Rather, they are intended to align, guide, parallelize, stretch and / or, in particular, hold the combed fibers transported back from the take-off rollers on the lower take-off roller. No aggressive meshing intervention is required. It would even be counterproductive. Rather, only a comparatively gentle touching of the already combed fibers that have been transported back is provided. This gentle fiber contact takes place in particular due to the negative element face or tooth face angle of the alignment elements.
  • the alignment elements are in particular arranged tangentially and preferably also axially distributed on the outside of the circular comb base body unit, so that the gentle fiber contact can preferably take place anywhere in the area of the alignment segment.
  • the gentle fiber contact per pass that is to say during one revolution of the circular comb, can even preferably take place several times.
  • this results in a particularly efficient alignment, guidance, stretching and / or parallelization of the already combed fibers that have been transported back.
  • these fibers are held very well on the lower take-off roller.
  • High-quality yarns with much fewer yarn defects (thick and thin places) can be produced from this. The result is yarns with a low CV value, which indicates the yarn uniformity.
  • the circular comb according to the invention with the alignment segment enables very high comb play numbers of the comber anyway consistently high quality of the fiber composite of the combed ridges. Comb cycle speeds of up to 600 revolutions per minute or even higher working speeds are possible.
  • the alignment segment can be manufactured inexpensively due to its structure, which is similar in particular to that of the combing segment.
  • the circular comb basic body unit of the circular comb according to the invention can consist of a one-part circular comb basic body. However, it can also comprise a multi-part circular comb base body. In addition, as optional additional components, it can in particular also have fastening clips for fastening the circular comb to the shaft of the comber.
  • the circular comb basic body unit or at least the circular comb basic body per se can in particular essentially have the basic shape of a circumferential segment of a hollow circular cylinder, the cylinder axis of the hollow circular cylinder being a central longitudinal axis of the circular comb basic body unit or the circular comb basic body, in particular coinciding with the axis of rotation.
  • the outside of the circular comb base body unit also preferably has an at least substantially partially circular cylindrical shape. This applies in particular at least to the area in which the combing segment is arranged, but can also apply in the area in which the alignment segment is located.
  • the outside of the circular comb base body unit can, however, in particular also have a geometry that deviates from the exact part-circular cylindrical shape. Despite this possible geometry deviating from the exact part-circular cylindrical shape, the outside can generally be understood as a tangential outside or outer peripheral side.
  • the location or direction information used here relates in particular in each case to the axis of rotation of the shaft or a cylinder coordinate system defined by this axis of rotation.
  • axial stands for an orientation in the direction of the axis of rotation
  • radial for an orientation perpendicular to the axis of rotation
  • tangential for an orientation in the circumferential direction about the axis of rotation.
  • the combing direction of the circular comb according to the invention is in particular the direction of rotation in which the circular comb rotates about the axis of rotation. In particular, it is one of the two circumferential directions about the axis of rotation.
  • Textile fibers are to be understood here in particular as wool fibers, cotton fibers, synthetic fibers, man-made fibers or also fibers which consist of a mixture of at least two of the fiber types mentioned above.
  • a configuration is favorable in which the alignment elements have a negative element breast angle in the range between -5 ° and -65 °, in particular between -5 ° and -40 ° and preferably between -8 ° and -30 °. Then the influence of the alignment elements on the part of the already combed fibers transported back by the take-off rollers is very effective on the one hand, but not too strong on the other hand.
  • the alignment elements have a board in the range between 0.5 mm and 4 mm, in particular between 0.8 mm and 2.5 mm and preferably between 1.5 mm and 2 mm.
  • the (free) board is in particular the radial dimension with which the alignment element protrudes over a base area.
  • this can be a tooth height if the alignment element is designed as an alignment tooth. It also applies to the above-mentioned dimensions of the board that the influence of the alignment elements on the part of the already combed fibers transported back by the take-off rollers is very effective on the one hand, but is not too strong on the other hand.
  • the alignment segment viewed in the combing direction, is arranged behind the comb segment and in particular directly adjoins the comb segment. This results in a small construction volume of the ridge. If the alignment segment and the comb segment are arranged directly adjacent to one another, it is also advantageously avoided that contaminants, such as dust, fiber components or the like, accumulate between the two segments. Such contaminants can loosen and get into the combed fiber material. Furthermore, it is advantageous if the transition between the combing segment and the alignment segment takes place largely continuously, that is to say in particular without substantial interruption and / or without an essential step, since otherwise turbulences can form.
  • the alignment elements each have alignment tips, and at least some of the alignment tips have a smaller, in particular radial, distance from the axis of rotation than comb tips of the comb teeth.
  • the combing tips lie in particular on a common circumferential surface which forms a circular cylindrical combing envelope, the alignment tips in particular not reaching this combing envelope.
  • the position of the alignment tips is in particular below the combing curve or within that of the combing curve enclosed interior.
  • a radial distance between the alignment tips and the combing envelope is in particular in the range between 0.5 mm and 9 mm, preferably between 0.5 mm and 6 mm and preferably between 1 mm and 4 mm. The above distances apply to at least some of the alignment tips.
  • This distance preferably has the effect that there is always an air flow past the lower take-off roller and directed downward, as a result of which the part of the already combed fibers transported back by the take-off rollers is nestled as closely as possible to the lower take-off roller. Due to this distance, the air flow is advantageously also present when the alignment element is moving past the part of the already combed fibers that is transported back by the take-off rollers.
  • an especially radial distance between the axis of rotation and alignment tips of the alignment elements decreases in the opposite direction to the combing direction. Accordingly, a radial distance between the alignment tips and the combing envelope increases counter to the combing direction.
  • This radial distance between the alignment tips and the combing envelope moves in particular in the range between 0 mm and 14 mm, preferably between 0.5 mm and 14 mm and preferably between 2 mm and 8 mm.
  • Such an increasing radial distance also favors the air flow past the lower take-off roller and directed downward.
  • the force with which the alignment elements act on the part of the combed fibers transported back by the take-off rollers can be adjusted.
  • This force on the returned fibers can initially, i. H. be stronger at the beginning of each period of exposure of the alignment elements to these fibers, since the fibers are still well clamped between the take-off rollers at the beginning.
  • This fiber clamping becomes smaller with increasing distance traveled back, so that the alignment elements should later only act with a lower force on the returned fibers.
  • Such a reducing action of force is achieved in particular in that the radial distance between the alignment tips and the combing envelope increases counter to the combing direction.
  • This measure also favors the air flow directed past the lower take-off roller and downwards.
  • it also serves to adapt to the fiber material to be processed, in particular with regard to the fineness, length and / or amount of the textile fibers contained in the fiber material, in order thus to optimize the result of the soldering process.
  • a ratio of a passage area of the free passage to a cross-sectional area of a protruding part of the alignment element perpendicular to the combing direction lies in the range between 0.17 and 4, in particular between 0.25 and 1.5 and preferably between 0.33 and 1
  • the free passage has a passage area that varies in opposite directions, in particular continuously decreases. Then, on the one hand, there is still enough free passage for the air flow that is directed past and downward to the air flow.
  • the active contact area increases in opposition to the combing direction, by means of which the aligning elements can come into contact with the part of the already combed fibers that is transported back by the draw-off rollers, in order to bring about the desired alignment, guidance, stretching and / or parallelization.
  • this measure makes the alignment effect at the end of the alignment segment seen against the combing direction still slightly increased, in order to influence the last remnants of not yet aligned fibers in this sense.
  • FIG. 1 An embodiment of a combing machine 1 for combing textile fibers 2 is shown, only a part of the components thereof

  • the combing machine 1 is operated with a high number of combs of, for example, up to 600 revolutions of the circular comb 16 per minute. This results in strong forces acting on the textile fibers 2 that are still to be combed, but also on the already combed textile fibers 11.
