Abstract

Teeth for fitting to the top comb or the combing cylinder are grouped as part of a solid block placed transversely to the combing direction. The teeth are in one piece with a solid back, which is shaped to form the attachment device. Preferably more than three teeth groups are placed in line in the combing direction. An independent claim is included for the method of producing the teeth by spark erosion from a solid block (10). Initially slots (12) are machined by a multiple erosion head (20). The tooth shape (52) and attachment zone (54) are then produced by profiling heads (30, 40) working simultaneously from both ends.

Description

Die Erfindung betrifft eine Kämmeinrichtung nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a combing device according to the preamble of patent claim 1.

Die Kämmmaschine dient zum Veredeln von aus Textilfasern hergestellten Garnen. Sie ist bei der Garnherstellung üblicherweise zwischen der Karde und der Strecke angeordnet. Die Hauptaufgaben der Kämmmaschine bestehen in der Ausscheidung von Kurzfasern aus dem von der Karde erzeugten Kardenbändern, d.h. in der Verbesserung des Stapels des Rohfasermaterials, sowie in der Verbesserung der Parallelisierung der einzelnen Fasern des in Form des Kardenbandes von der Karde gelieferten Faservlieses. Als Nebeneffekt wird in der Kämmmaschine eine weitere Reinigung des Faservlieses durch Ausscheiden von Nissen und Schalenteilen erreicht. Zum Erhalt der vorstehend beschriebenen Verbesserungen des Faservlieses wird in der Kämmmaschine ein von einem Speisezylinder zugeführter und von einer Zange gehaltener Faserbart des Faservlieses von einem eine raumfeste Achse umlaufenden Rundkamm durchfahren, mit einem bereits gekämmten Kämmvlies verlötet und durch Eingreifen eines Fixkamms in den vom Rundkamm gekämmten Faserbart und gleichzeitiges Abziehen des Kämmvlieses vom Speisezylinder vom noch zu kämmenden Faservlies abgerissen. Die gewünschte Verbesserung der Parallelität der Einzelfasern des Faservlieses sowie die Stapelverbesserung durch Ausscheidung von Kurzfasern wird dabei durch das Zusammenwirken von Rundkamm und Fixkamm bewirkt.The combing machine serves to refine yarns made from textile fibers. It is usually arranged between the card and the track during yarn production. The main tasks of the comber consist in the excretion of short fibers from the card sliver produced by the card, ie in the improvement of the stack of raw fiber material, as well as in the improvement of the parallelization of the individual fibers supplied in the form of the card sliver of the carding nonwoven fabric. As a side effect, a further cleaning of the fiber fleece is achieved in the combing machine by excreting nits and shell parts. To obtain the above-described improvements of the nonwoven fabric is in the combing a supplied by a feed cylinder and held by a pliers tuft of the nonwoven fabric of passing through a solid axis rotating circular comb, soldered with an already combed combing fleece and demolished by intervention of a fixed comb in combed by the circular comb tuft and simultaneous removal of Kämmvlieses from the feed cylinder to be combed nonwoven fabric. The desired improvement of the parallelism of the individual fibers of the nonwoven fabric and the stack improvement by precipitation of short fibers is effected by the interaction of the circular comb and the top comb.

Der Fixkamm herkömmlicher Kämmmaschinen ist üblicherweise aus einem Trägerelement in Form eines Blechstreifens und daran angelöteten Kammzinken in Form von Flachnadeln gebildet. Insbesondere bei hohen Arbeitsgeschwindigkeiten der Kämmmaschine hat es sich gezeigt, daß mit dem Einsatz derartiger Fixkämme keine den Anforderungen an hochwertige Garne genügende Parallelisierung der einzelnen Fasern des Faservlieses erreichbar ist, während gleichzeitig eine starke Verunreinigung des Fixkammes zu beobachten ist, die eine häufige Reinigung notwendig macht. Zur Beseitigung dieses Mangels wird in der DE 195 31 605 eine Weiterbildung herkömmlicher Fixkämme vorgeschlagen, bei der die Kammzinken des Fixkammes ebenso wie die Kammzinken des Rundkamms in Form von Sägezahndrahtabschnitten mit jeweils mindestens einem Sägezahn, der im wesentlichen parallel zur Kämmrichtung verlaufende Zahnflanken und eine senkrecht dazu verlaufende Zahnbrust aufweist, gebildet sind. Dabei können die zur Herstellung des Fixkamms benutzten Sägezahndrahtabschnitte ebenso wie die zur Herstellung des Rundkamms eingesetzten Sägezahndrahtabschnitte jeweils aus einem Fuß und einem daran anschließenden, den mindestens einen Sägezahn aufweisenden Blatt bestehen, wobei die Abmessungen des Fußes in einer im wesentlichen senkrecht zur Kämmrichtung verlaufenden Richtung größer sind als die Abmessungen des Blattes in dieser Richtung, um so den Durchgang der Fasern durch die entsprechenden Kämmelemente während des Kämmvorgangs ermöglichend die Kammgassen bereitzustellen.The top comb conventional combing machines is usually formed of a support element in the form of a metal strip and soldered comb teeth in the form of flat needles. In particular, at high operating speeds of the combing machine, it has been found that with the use of such Fixkämme no requirements for high-quality yarns sufficient parallelization of the individual fibers of the nonwoven fabric can be reached while a strong contamination of the fixed comb is to be observed, which makes frequent cleaning necessary , To eliminate this deficiency will be in the DE 195 31 605 a development of conventional fixed combs proposed in which the comb teeth of the top comb as well as the comb teeth of the circular comb in the form of sawtooth wire sections, each with at least one saw tooth, which has substantially parallel to the combing tooth flanks and a perpendicular thereto extending tooth face, are formed. In this case, the sawtooth wire sections used for the production of the fixed comb, as well as the sawtooth wire sections used to make the circular comb may each consist of a foot and an adjoining sheet having at least one sawtooth, the dimensions of the foot being greater in a direction substantially perpendicular to the combing direction are as the dimensions of the sheet in this direction, so as to provide for the passage of the fibers through the respective combing elements during the combing process enabling the combs.

Zur Herstellung derartiger Kämmeinrichtungen wird ein drahtförmiges Ausgangsmaterial zunächst einem Kaltwalzvorgang unterzogen, um so ein den Fußbereich und den Blattbereich der Sägezahndrahtabschnitte bildendes Drahtprofil zu erzeugen. In einem nächsten Fertigungsschritt werden die Sägezähne durch einen Stanzvorgang aus dem Profildraht herausgelöst. Von dem so erhaltenen Sägezahndraht werden Sägezahndrahtabschnitte mit einer für die Herstellung eines Fixkamms bzw. eines Rundkamms benötigten Länge abgeschnitten. Die Sägezahndrahtabschnitte werden dann zu Bündeln zusammengefaßt und auf einem geeigneten Trägerelement befestigt. Nach der Herauslösung der Sägezähne aus dem Blattabschnitt des Profildrahts können die Sägezähne einem Härtungsvorgang, wie etwa einem Laser - oder Flammhärtungsvorgang unterzogen werden. Wie der vorstehenden Erläuterung herkömmlicher Kämmeinrichtungen für Fixkämmmaschinen zu entnehmen ist, verursacht deren Herstellung einen beachtlichen Aufwand. Ferner sind Kämmeinrichtungen nach dem Oberbegriff des Patentanspruchs 1 aus der GB-A-1 264 306 bekannt. Angesichts dieser technischen Probleme liegt der Erfindung die Aufgabe zugrunde eine besonders einfach herstellbare Kämmeinrichtung für Kämmmaschinen bereitzustellen, mit der bei einer hohen Maschinenlaufzeit und - Arbeitsgeschwindigkeit ein qualitativ hochwertiger Kammzug bzw. ein qualitativ hochwertiges Kämmmaschinen-Band herstellbar ist, sowie ein Verfahren zur Herstellung solcher Kämmeinrichtungen bereitzustellen.To produce such combing devices, a wire-shaped starting material is first subjected to a cold rolling process, so as to produce a wire profile forming the root area and the blade area of the sawtooth wire sections. In a next manufacturing step, the saw teeth are removed by a punching process from the profile wire. From the sawtooth wire thus obtained sawtooth wire sections are cut with a required for the production of a Fixkamms or a circular comb length. The sawtooth wire sections are then combined into bundles and mounted on a suitable support member. After the detachment of the saw teeth from the blade section of the profile wire, the saw teeth a Curing process such as a laser or flame hardening process. As the above explanation of conventional combing for Fixkämmmaschinen can be seen, their production causes considerable effort. Further combing devices are according to the preamble of claim 1 of the GB-A-1 264 306 known. In view of these technical problems, the object of the invention is to provide a combing device for combing machines that is particularly easy to produce, with which a high-quality combing belt or a high-quality comber belt can be produced at a high machine running time and operating speed, as well as a method for producing such combing devices provide.

Erfindungsgemäß wird diese Aufgabe durch die im kennzeichnenden Teil des Anspruchs 1 angegebene Weiterbildung der herkömmlichen Kämmeinrichtungen gelöst. Vorteilhafte Weiterbildungen der Erfindung sind in den abhängigen Ansprüchen angegeben.According to the invention this object is achieved by the specified in the characterizing part of claim 1 development of conventional combing. Advantageous developments of the invention are specified in the dependent claims.

Bei herkömmlichen Kämmeinrichtungen erfolgt die Festlegung der Kammzinken über besondere Befestigungselemente, an denen die Kammzinken befestigt werden müssen. Bei den Kämmelementen erfindungsgemäßer Kämmeinrichtungen kann der zum Befestigen des Kämmelementes an der Kämmmaschine ausgelegte Befestigungsbereich auch einstückig mit den Kammzinken ausgeführt sein.In conventional combing the determination of the comb teeth on special fasteners where the comb teeth must be attached. In the combing elements of combing devices according to the invention, the fastening region designed for fastening the combing element to the combing machine can also be embodied in one piece with the comb teeth.

Insbesondere beim Einsatz erfindungsgemäßer Kämmeinrichtungen in Form von Rundkämmen für eine Kämmmaschine, aber auch beim Einsatz erfindungsgemäßer Kämmeinrichtungen in Form von Fixkämmen für eine Kämmmaschine hat es sich zum Erhalt einer besonders guten Kämmwirkung als zweckmäßig erwiesen, wenn das Kämmelement mindestens zwei, vorzugsweise drei oder mehr in Kämmrichtung hintereinander angeordnete Kammzinken aufweist. Beim Einsatz erfindungsgemäßer Kämmeinrichtungen in Form von Fixkämmen sind die Spitzen der in der senkrecht zur Kämmrichtung verlaufenden Richtung nebeneinander angeordneten Kammzinken zweckmäßigerweise etwa auf einer senkrecht zur Kämmrichtung verlaufenden Geraden angeordnet. Die Spitzen der in Kämmrichtung hintereinander angeordneter Kammzinken sind beim Einsatz erfindungsgemäßer Kämmeinrichtungen in Form von Rundkämmen vorzugsweise etwa auf einem Kreisbogen angeordnet, dessen Mittelpunkt auf die von dem Rundkamm umlaufene raumfeste Achse fällt.In particular, when using combing devices according to the invention in the form of circular combs for a combing machine, but also when using combing devices according to the invention in the form of Fixkämmen for a comber, it has proven to be particularly useful for obtaining a particularly good combing when the combing at least two, preferably three or more in Combing one behind the other arranged comb teeth has. When using combing devices according to the invention in the form of fixed combs, the tips of the comb teeth arranged next to one another in the direction perpendicular to the combing direction are expediently arranged approximately on a straight line running perpendicular to the combing direction. The tips of the combing in succession arranged comb teeth are preferably arranged when using combing devices according to the invention in the form of circular ridges approximately on a circular arc, the center of which falls on the space-fixed axis circumscribed by the circular ridge.

Zur Herstellung erfindungsgemäßer Kämmeinrichtungen ist es nicht mehr erforderlich, ein Ausgangsmaterial zunächst einem Kaltwalzvorgang und danach einem anschließenden Stanzvorgang zu unterziehen. Daher können die Kämmelemente erfindungsgemäßer Kämmeinrichtungen zumindest teilweise aus hochlegiertem Stahl, insbesondere rostfreiem Chrom-Nickel-Stahl, hergestellt sein, dessen Kaltverformungseigenschaften zur Herstellung von Profildrähten nicht mehr ausreichen würden.For the production of combing devices according to the invention, it is no longer necessary to first subject a starting material to a cold rolling process and then to a subsequent punching operation. Therefore, the combing elements of combing devices according to the invention can be at least partially made of high-alloy steel, in particular stainless chromium-nickel steel, whose cold-forming properties would no longer be sufficient for producing profiled wires.

Wie der vorstehenden Erläuterung erfindungsgemäßer Kämmeinrichtungen zu entnehmen ist, zeichnet sich ein zu deren Herstellung geeignetes Kämmelement im wesentlichen dadurch aus, daß es mindestens zwei, vorzugsweise drei oder mehr (ggf. 20, 30 oder mehr) in der senkrecht zur Kämmrichtung verlaufenden Richtung nebeneinander angeordnete und einstückig ausgeführte Kammzinken aufweist.As can be seen from the above explanation of combing devices according to the invention, a combing element suitable for the production thereof is essentially characterized in that it has at least two, preferably three or more (possibly 20, 30 or more) arranged side by side in the direction perpendicular to the combing direction and integrally executed comb teeth.

Ein unter Einsatz entsprechender Kämmelemente erhaltener erfindungsgemäßer Fixkamm ist im wesentlichen dadurch gekennzeichnet, daß er zwei, drei oder mehr einstückig ausgeführte Kammzinken aufweist, deren Zahnspitzen auf einer etwa senkrecht zur Kämmrichtung verlaufenden Geraden angeordnet sind. Ein unter Einsatz erfindungsgemäßer Kämmelemente hergestellter Rundkamm umfaßt sowohl zwei, drei oder mehr in einer senkrecht zur Kämmrichtung verlaufenden Richtung nebeneinander angeordneter und einstückig ausgeführter Kammzinken, als auch zwei, drei oder mehr in der Kämmrichtung hintereinander angeordnete und einstückig ausgeführte Kammzinken. Dabei können sowohl zur Herstellung erfindungsgemäßer Fixkämme, als auch zur Herstellung erfindungsgemäßer Rundkämme zwei, drei oder mehr erfindungsgemäße Kämmelemente in einer senkrecht zur Kämmrichtung verlaufenden Richtung nebeneinander angeordnet werden, wobei insbesondere zur Herstellung erfindungsgemäßer Rundkämme auch zwei, drei oder mehr erfindungsgemäße Kämmelemente in der Kämmrichtung hintereinander angeordnet werden können.An invention according to the invention obtained using combing combs fixed comb is essentially characterized in that it two, three or more has integrally executed comb teeth whose tooth tips are arranged on a straight line extending approximately perpendicular to the Kämmrichtung. A circular comb produced using combing elements according to the invention comprises two, three or more comb teeth arranged side by side in a direction perpendicular to the combing direction and integrally executed, as well as two, three or more comb teeth arranged one behind the other in the combing direction and integrally formed. Two, three or more combing elements according to the invention can be arranged side by side in a direction perpendicular to the combing direction both for the production of inventive combs and for producing circular combs according to the invention, wherein two, three or more combing elements according to the invention in the combing direction behind each other in particular for the production of circular combs according to the invention can be arranged.

Ein Verfahren zum Herstellen eines erfindungsgemäßen Kämmelementes für eine erfindungsgemäße Kämmeinrichtung ist im wesentlichen dadurch gekennzeichnet, daß ausgehend von einem beispielsweise etwa quaderförmigen Rohmaterialblock, insbesondere aus hochlegiertem Stahl, wie etwa Chrom-Nickel-Stahl, in einem ersten Bearbeitungsschritt die einzelnen Kammzinken in der senkrecht zur Kämmrichtung verlaufenden Richtung voneinander trennende Schlitze in dem Rohmaterial gebildet und anschließend in einem zweiten Bearbeitungsschritt die Form der Kammzinken in einer senkrecht zur Kämmrichtung geführten Ansicht aus dem Rohmaterialblock herausgelöst wird, wobei ein die Kammzinken in der senkrecht zur Kämmrichtung verlaufenden Richtung miteinander verbindender Verbindungsbereich sowie ggf. der zur Befestigung des Kämmelementes an der Kämmmaschine dienende Befestigungsbereich des Rohmaterialblocks erhalten bleibt.A method for producing a combing element according to the invention for a combing device according to the invention is characterized essentially in that starting from an example approximately cuboid raw material block, in particular made of high-alloy steel, such as chromium-nickel steel, in a first processing step, the individual comb teeth in the perpendicular to Then, in a second processing step, the shape of the comb teeth is removed from the raw material block in a view perpendicular to the combing direction, wherein a connection region connecting the comb teeth in the direction perpendicular to the combing direction is used. the fastening area of the raw material block serving to fasten the combing element to the combing machine is maintained.

Im Sinne einer rationellen Fertigung erfindungsgemäßer Kämmelemente und Kämmeinrichtungen hat es sich als besonders zweckmäßig erwiesen, wenn in dem ersten Bearbeitungsschritt zwei, drei oder mehr Schlitze gleichzeitig gebildet werden. Eine rationelle Fertigung erfindungsgemäßer Kämmelemente bzw. Kämmrichtungen kann unter Sicherstellung der benötigten hohen Fertigungsgenauigkeit sichergestellt werden, wenn der erste und/oder zweite Bearbeitungsschritt mittels Funkenerosion, ggf. Funkentiefenerosion ausgeführt wird, wobei zur gleichzeitigen Bildung von zwei, drei oder mehr Schlitzen in dem Rohmaterialblock und/oder zur gleichzeitigen Herauslösung von zwei, drei oder mehr in der Kämmrichtung hintereinander angeordneten Sägezähnen Multierodierköpfe zum Einsatz kommen können.In the sense of a rational production of combing elements and combing devices according to the invention, it has proved particularly expedient if two, three or more slots are formed simultaneously in the first processing step. A rational production of combing elements or combing directions according to the invention can be ensured while ensuring the required high manufacturing accuracy, if the first and / or second processing step by spark erosion, if necessary sparkling depth erosion is carried out, wherein for the simultaneous formation of two, three or more slots in the raw material block and / or for the simultaneous detachment of two, three or more in the Kämmrichtung successively arranged saw teeth Multierodierköpfe can be used.

Eine weitere Beschleunigung erfindungsgemäßer Herstellungsverfahren ist möglich, wenn der Rohmaterialblock bei dem zweiten Bearbeitungsschritt aus zwei einander entgegengesetzten und jeweils senkrecht zur Kämmrichtung verlaufenden Richtungen bearbeitet wird.A further acceleration of production methods according to the invention is possible if the raw material block in the second processing step is machined from two directions which are opposite one another and in each case perpendicular to the direction of combing.

Nachstehend wird die Erfindung anhand der Zeichnung, auf die hinsichtlich aller erfindungswesentlichen und in der Beschreibung nicht näher herausgehobenen Einzelheiten ausdrücklich verwiesen wird, erläutert. Die einzige Figur der Zeichnung veranschaulicht schematisch ein Verfahren zur Herstellung erfindungsgemäßer Kämmelemente, die zur Fertigung erfindungsgemäßer Fixkämme geeignet sind. Gemäß der Zeichnung wird als Ausgangsmaterial für den Herstellungsvorgang ein Röhmaterialblock, beispielsweise aus rostfreiem, hochlegiertem Stahl, wie etwa Chrom-Nickel-Stahl verwendet. Die Breite b dieses Rohmaterialblocks kann bis zu 300 mm betragen, die Höhe h des Rohmaterials kann 5 bis 15 cm, insbesondere etwa 10 cm betragen. Die Tiefe t des Rohmaterialblocks kann 1 bis 10 mm insbesondere 3 bis 5 mm betragen. Bei dem in der Zeichnung schematisch dargestellten Herstellungsverfahren werden in einem ersten Bearbeitungsschritt mittels Funkenerosion unter Verwendung eines Multierosionskopfes 20 die Kammzinken in einer senkrecht zur Kämmrichtung verlaufenden Richtung P voneinander trennende Schlitze 12 aus dem Rohmaterialblock 10 herausgelöst. Dabei werden mit Hilfe des Multierosionskopfs 20 gleichzeitig drei Schlitze 12 hergestellt. Bei anderen Ausführungsformen der Erfindung können vier oder mehr Schlitze 12 bzw. 2 oder weniger Schlitze 12 gleichzeitig hergestellt werden. In einem zweiten Bearbeitungsschritt werden gleichzeitig mit Hilfe von Erosionsköpfen 30 und 40 Profile 50 in einer senkrecht zur Kämmrichtung geführten Ansicht aus zwei einander entgegengesetzten und jeweils senkrecht zur Kämmrichtung verlaufenden Richtungen aus dem Rohmaterialblock 10 herausgelöst. Diese Profile können einen die Kammzinken miteinander verbinden Befestigungsbereich 54 unterhalb der Schlitze 12 und sägezahnförmige Kammzinken 52 aufweisen.The invention will be explained with reference to the drawing, to which reference is expressly made with respect to all essential to the invention and in the description not highlighted details. The sole figure of the drawing illustrates schematically a method for producing inventive combing elements, which are suitable for the production of inventive fixed combs. As shown in the drawing, as the starting material for the manufacturing process, a block of raw material, for example, stainless high-alloy steel such as chromium-nickel steel is used. The width b of this raw material block can be up to 300 mm, the height h of the raw material can be 5 to 15 cm, in particular about 10 cm. The depth t of the raw material block may be 1 to 10 mm, in particular 3 to 5 mm. In the manufacturing method shown schematically in the drawing, in a first processing step by spark erosion using a multi-erosion head 20, the comb teeth in a direction perpendicular to the direction of combing direction P separating slits 12 separated from the raw material block 10. In this case, three slots 12 are simultaneously produced with the aid of the multi-erosion head 20. In other embodiments of the invention, four or more slots 12 or 2 or fewer slots 12 may be made simultaneously. In a second processing step, profiles 50 are simultaneously removed from the raw material block 10 in a direction perpendicular to the combing direction by means of erosion heads 30 and 40 from two opposite and respectively perpendicular directions to the combing direction. These profiles may have a connecting the comb teeth with each other fastening region 54 below the slots 12 and sawtooth-shaped comb teeth 52.

In beiden Bearbeitungsschritten können Funkenerosionsverfahren zum Einsatz kommen. Mit Hilfe derartiger Verfahren können anders als bei herkömmlichen Verfahren zur Herstellung von Kämmeinrichtungen für Kämmmaschinen Kammzinken 52 beliebiger Form, insbesondere beliebiger Brustform und beliebig profilierte Zinken bzw. Zahnflanken hergestellt werden. Dabei können die Flanken der zahnförmigen Zinken 52 beispielsweise abschnittweise in Richtung auf die Zahnspitzen symmetrisch bezüglich einer senkrecht zur Richtung P verlaufenden Ebene konvergieren. Die Erfindung ist nicht auf die anhand der Zeichnung erläuterte Ausführungsform beschränkt. Vielmehr ist auch an die Herstellung von Rundkammgarnituren mit Hilfe erfindungsgemäßer Verfahren gedacht. Dabei können zur Herstellung der Zahnprofile auch im zweiten Bearbeitungsschritt Multierosionsköpfe zum Einsatz kommen. Weiter ist an die Herstellung von Kammzinken mit beliebigen Zinkenformen gedacht.In both processing steps, spark erosion methods can be used. With the aid of such methods, unlike conventional methods for producing combing devices for combing machines, comb teeth 52 of any shape, in particular any breast shape, and optionally profiled teeth or tooth flanks can be produced. In this case, the flanks of the tooth-shaped prongs 52 may, for example, converge in sections in the direction of the tooth tips symmetrically with respect to a plane perpendicular to the direction P. The invention is not limited to the embodiment explained with reference to the drawing. Rather, it is also connected to the production of Rundkammgarnitur intended by means of inventive method. In this case, multi-erosion heads can also be used in the second processing step to produce the tooth profiles. Next is intended to the production of comb teeth with any tine shapes.
