Definitions

  • the invention relates to a fixed comb of a combing machine with a Fixkammarme which has a holding portion which is connected to a support plate on which a pin strip, or a Fixkammgarnitur is attached.
  • the comb of a combing machine is subjected to alternating dynamic loads during the combing process, which in part make themselves noticeable in an elastic deformation of the fixing comb, in particular in its longitudinal direction. This in turn affects the attachment points of the Fixkammes in the combing machine. This means that due to the occurring elastic deflection of the fixed comb, transversely to its longitudinal direction, relative movements occur between the fixedly mounted holding elements (eg holding clips) and the holding section of the fixing comb. As a result, the holding section is subject to wear in this area.
  • the number of combing heads eight fixed combs are used on a combing machine.
  • the distance between the Fixkammgarnitur, or the pin strip is kept as low as possible to the subsequent Abreisswalzen. If, as a result of the dynamic load transversely to the longitudinal direction of the top comb, a deflection occurs, this must be taken into account in the positioning of the top comb during installation. This means that the minimum distance of the fixed comb to the tear-off rollers is to be selected larger by the amount of deflection in order to avoid a collision of the fixed comb during its combing position with the tear-off rollers.
  • the EP 0 580 549 A1 discloses a fixed comb having the features of the preamble of claim 1.
  • the invention has the object to avoid the disadvantages mentioned and to propose a compact design of a fixed comb with increased bending strength, whereby the relative movements between the holding portion of the Fixkammes and its fasteners are minimized. At the same time, care must be taken to ensure that the mass of the top comb is changed only slightly and that the narrow geometrical mounting mass of the top comb between the nipper unit and the puller rollers is taken into account.
  • longitudinal direction refers to the length of the fixed comb, which extends in the installation position in the combing machine transversely to the direction of flow of the fiber material.
  • the mass of the fixed comb is increased slightly.
  • the stiffening element can be mounted in the area in which it is not a hindrance despite the tight installation conditions.
  • the stiffening element is therefore - seen in the installation position of the fixed comb - mounted on the side of the support plate, which faces the subsequent Abreisswalzen. This corresponds - seen in the flow direction of the fiber material - the front side of the support plate.
  • the stiffening element - viewed in the longitudinal direction of the Fixkammippos - extending from the center of the Fixkammmiks in the direction of its two ends and has a distance from the ends of the Fixkammmiks. This makes it possible that in the respective remaining free area between the ends of the stiffening element and the respective end of the Fixkammembls holding elements for fixing the Fixkammes, as previously known, can be used.
  • the stiffening element is connected to the holding section and the carrier plate.
  • the stiffening element is formed together with the holding portion and the support plate as a hollow profile.
  • the stiffening element is formed together with the holding portion and the support plate as a hollow profile.
  • an increase in the bending strength of the Fixkammmiks is achieved transversely to its longitudinal extent, which also has an advantageous effect on the constant maintenance of the position of the tips of the Fixkammgarnitur during the tearing or combing process.
  • the hollow profile-seen in cross-section has a cross-sectional area which decreases in the direction of the tips of the needle strip.
  • the fixed comb carrier formed from the holding section, the carrier plate and the stiffening element is manufactured in one piece.
  • the extruded profile may consist of a non-metallic material for weight reduction, z. B. of an aluminum alloy.
  • Fig. 1 shows a cross section of an inventively designed Fixkammongs 2 a Fixkammes 1 with a combing machine, not shown.
  • the Fixkammong 2 is formed from a holding portion 4, to which a support plate 5 is attached.
  • the holding section 4 has the cross-sectional shape of an open profile with an arcuate outer surface.
  • the holding section 4 and the carrier plate 5 may be made of one piece (eg of plastic or of an extruded aluminum alloy).
  • a stiffening element 11 is attached, which, as from FIG. 2 can be seen almost over the entire length of the Fixkammmiks 2 extends. It would also be conceivable to provide a plurality of mutually spaced stiffening elements, which are mounted over the length of the Fixkammismes 2. However, the greatest effect in terms of increasing the flexural strength is obtained when, as in FIG. 2 shown the stiffening element 11 is formed continuously. How out FIG.
  • the stiffening element 11 is connected to the holding section 2 at one end and to the carrier plate 5 at the other end. Together with the holding portion 4 and the support plate 5, the stiffening element 11 forms a hollow profile with a triangular cross-section.
  • a Fixkammgarnitur 7 is attached via a plurality of screws 14 and a clamping plate 15. According to the number of screws 14 threaded holes 16 are mounted in the support plate 15. About the screws 14 and the clamping plate 15, the clothing 7 is clamped on the support plate 5.
  • the clothing 7 of the fixed comb 1 can be made of strung pinstripes, of juxtaposed stamped or embossed sheets or in any other form. However, this is irrelevant to the presentation of the invention.
  • FIG. 2a schematically shows how the deflection b of the support plate 5 of the Fixkammismes 2 by the resulting force F takes place in the flow direction D.
  • the fiber tuft combed out by means of a circular comb is subsequently pulled in the flow direction D over the tear-off rollers through the clothing 7 of the fixing comb 1 during the tearing process.
  • deflection b of the carrier plate 5 occurs, in particular in the middle region of the fixed comb 2. This is an elastic deflection which oscillates back after the force F has been eliminated. Ie. at a Kammspielteil of z. B. 500 KS / min, this process is 500 times per minute.
  • FIG. 3 View Y
  • the retaining clip 21 is formed at its free end so that it a latching position when reaching over the arcuate outer contour of the holding section 4 occupies.
  • the function of this retaining clip is also from the embodiments of DE-102 52 098 A1 refer to.
  • the dashed line 21 'in FIG. 3 shows the retaining clip 21 in its unlocked position, wherein the Fixkammisme 2 can be taken out of a slot 19 of a vertical receptacle 18 of the Fixkammhalters 17 upwards.
  • two such Fixkammhalter 17 are attached to a nipper unit, not shown.
  • the holding section 4 in the region of its fastenings 21 will be closed by the described relative movements.
  • the deflection b is considerably reduced and thus reduced the risk of wear in the area of stops. By reducing the deflection to a minimum, it is also ensured that the geometrical combing conditions remain substantially constant over the entire length of the fixing comb 1.
  • the stiffening element 12 may be formed from a non-metallic material (eg plastic) so that the mass of the fixed comb to be moved is increased only insignificantly by the attachment of an additional stiffening element.
  • a non-metallic material eg plastic
