Abstract

The combing cylinder (1) for a combing machine has a combing segment (3) which is attached to the cylinder body (2) and has an aerofoil shape. Between the inner surface (8) of the combing segment (3) and the shell surface (9) of the cylinder body there is disposed an air duct (11). The interaction of the aerofoil shape of the combing segment (3) and the air duct (11) produces a suction effect which ensures that the teeth (6) of the combing segment (3) get an early grip on any fibre tuft (13) to be combed out. …<IMAGE>…

Description

Die Erfindung betrifft einen Kämmzylinder für eine Kämmaschine gemäss dem Oberbegriff von Anspruch 1.The invention relates to a combing cylinder for a combing machine according to the preamble of claim 1.

Kämmaschinen werden zum Auskämmen von Fasern einge­setzt. Beim Auskämmen werden die Einzelfasern des von einer Zange festgehaltenen Faserbartes parallel ausge­richtet und Verunreinigungen und Faserknötchen ent­fernt. Der wirksame Teil der Kämmaschine ist ein auf einem Zylinderkörper sitzendes Kämmsegment, dessen Aussenfläche in mehrere Reihen angeordnete Zähne oder Nadeln aufweist. Diese Zähne oder Nadeln des Kämmseg­mentes erfassen und kämmen den von einer Zange angelie­ferten Faserbart. Sie können ihre Wirksamkeit nur dann voll entfalten, wenn sie vom Einsetzen der Kämmperiode an, d.h. vom Zeitpunkt an, bei dem der Anfang des Kämm­segmentes auf dem sich drehenden Zylinder bei der Oeff­nung der Zange angelangt ist, den Faserbart erfassen. Diese Bedingung ist im allgemeinen, insbesondere bei hohen Drehzahlen des Kämmzylinders, nicht erfüllt, denn die vordersten Nadeln oder Zähne erfassen den Faserbart erst in einem Zeitpunkt, in dem sie sich bereits wieder von der Zange entfernt haben.Combing machines are used to comb out fibers. When combing out the individual fibers of the fiber beard held by a pair of pliers are aligned in parallel and impurities and fiber nodules are removed. The effective part of the combing machine is a combing segment seated on a cylinder body, the outer surface of which has teeth or needles arranged in several rows. These teeth or needles of the comb segment capture and comb the fiber beard supplied by a pair of pliers. They can only be fully effective if they commence from the onset of the combing period, i.e. from the point at which the beginning of the comb segment on the rotating cylinder has reached the opening of the pliers, grasp the fiber beard. This condition is generally not met, especially at high speeds of the combing cylinder, because the foremost needles or teeth only grasp the fiber beard at a point in time when they have already moved away from the pliers.

Um das Erfassen des Faserbartes bereits in einem frühe­ren Zeitpunkt zu ermöglichen, schlägt die US-PS 3 922 757 vor, den Abstand zwischen dem Unterteil der Zange und dem Anfang des Kämmsegmentes zu verkleinern, indem - durch besondere Formgebung - der Anfang des Kämmsegmentes zur Drehachse des Zylinders einen grösseren Abstand aufweist als das Ende des Kämmseg­mentes. Dadurch wird der Anfang des Kämmsegmentes der Oeffnung der Zange stark angenähert. Trotzdem wird der Faserbart, insbesondere bei schnell laufenden Maschi­nen, nicht bereits am Anfang der Kämmperiode erfasst, so dass das Kämmsegment nicht über die ganze Kämm­periode wirksam ist.In order to make it possible to grasp the fiber beard at an earlier point in time, US Pat. No. 3,922,757 suggests reducing the distance between the lower part of the pliers and the beginning of the comb segment by - through a special shape - the beginning of the comb segment relative to the axis of rotation of the cylinder one has a greater distance than the end of the comb segment. This closely approximates the beginning of the comb segment to the opening of the pliers. Nevertheless, the fiber beard, especially in the case of high-speed machines, is not detected at the beginning of the combing period, so that the combing segment is not effective over the entire combing period.

Aufgabe der vorliegenden Erfindung war es daher, einen Kämmzylinder vorzusehen, dessen Kämmsegment während der ganzen Kämmperiode voll wirksam ist, d.h. der den Faserbart bereits bei der Oeffnung der Zange erfasst.The object of the present invention was therefore to provide a combing cylinder, the combing segment of which is fully effective during the entire combing period, i.e. which already detects the fiber beard when the pliers are opened.

Diese Aufgabe wird durch die Merkmale des kennzeich­nenden Teils von Anspruch 1 gelöst.This object is solved by the features of the characterizing part of claim 1.

Diese Lösung beruht auf der Erkenntnis, dass die unge­nügende Erfassung des Faserbartes durch das Kämmsegment nicht, wie die US-PS annimmt, durch die zu grosse Ent­fernung zwischen Zange und Kämmsegment verursacht wird, sondern durch die beim Drehen des Kämmzylinders vor­rückende Front des Kämmsegmentes verdrängte Luft, die den Faserbart anhebt und somit aus dem Weg des Kämmseg­mentes führt.This solution is based on the knowledge that the inadequate detection of the fiber beard by the comb segment is not caused by the excessive distance between the pliers and comb segment, as assumed by the US-PS, but by the front of the comb segment which is displaced when the comb cylinder rotates , which raises the fiber beard and thus leads out of the way of the comb segment.

Durch die erfindungsgemässe Ausgestaltung des Kämm­zylinders wird die negative Wirkung der bewegten Luft nicht nur eliminiert, sondern durch das Zusammenwirken des Tragflügelprofils des Kämmsegmentes mit dem Luft­kanal zwischen Kämmsegment-Innenfläche und Zylinder­mantelfläche wird eine Saugwirkung zum Heranführen des Faserbartes an den Anfang des Kämmsegmentes erzeugt. Das Heranführen bewirkt einerseits ein frühes Erfassen und andererseits ein besseres Durchdringen des Faser­bartes durch die Zähne des Kämmsegmentes und mithin ein wirksameres Kämmen. Mit anderen Worten, der Luftstrom wirkt hier wie eine zweite, am freien Ende des Faser­bartes angreifende, Zange, die den Faserbart auf die Zähne des Kämmsegmentes zuführt.The inventive design of the combing cylinder not only eliminates the negative effect of the moving air, but also creates a suction effect for bringing the fiber beard to the beginning of the combing segment through the interaction of the wing profile of the combing segment with the air duct between the combing segment inner surface and the cylindrical surface. On the one hand, the approach leads to an early detection and, on the other hand, better penetration of the beard through the teeth of the combing segment and consequently more effective combing. In other words, the air flow acts here like a second pair of pliers, which acts on the free end of the fiber beard and which feeds the fiber beard onto the teeth of the comb segment.

Die Anordnung des - vorzugsweise auf das Ende des Kämm­segmentes zu - sich verbreiternden Luftkanals zwischen dem Kämmsegment mit Tragflügelprofil und Zylinderkörper ergibt an der Aussenseite des Kämmsegmentes eine Unter­druckzone und an der Innenseite, d.h. zwischen Kämm­segment und Zylinderkörper, eine Ueberdruckzone. Die Profilnase wird zur Minimalisierung des Einflusses eines falschen Anströmwinkels vorzugsweise relativ dick ausgebildet, was insbesondere bei instabilen, kompli­zierten Strömungsverhältnissen vorteilhaft ist. Obwohl der Strömungswiderstand hier eine verhältnismässig geringfügige Rolle spielt, ist eine dicke Profilnase mit einem erhöhten Strömungswiderstand in erster Linie für niedrige Drehzahlen des Kämmzylinders geeignet.The arrangement of the air channel, which preferably widens towards the end of the comb segment, between the comb segment with the wing profile and the cylinder body results in a vacuum zone on the outside of the comb segment and on the inside, i.e. between comb segment and cylinder body, an overpressure zone. The profile nose is preferably designed to be relatively thick in order to minimize the influence of an incorrect inflow angle, which is particularly advantageous in the case of unstable, complicated flow conditions. Although the flow resistance plays a relatively minor role here, a thick profile nose with an increased flow resistance is primarily suitable for low speeds of the combing cylinder.

Um das Erfassen des Faserbartes bereits im frühest möglichen Zeitpunkt zu sichern, ist die Zahn- oder Nadelfront des Kämmsegmentes gegenüber der Profilnase zurückgesetzt angeordnet, so dass die Saugwirkung bereits vor dem Einsetzen der Kämmperiode entfaltet wird und der durch die Saugwirkung herangeführte Faserbart vom Anfang des Kämmsegmentes erfasst wird.In order to ensure that the beard is grasped at the earliest possible time, the tooth or needle front of the comb segment is set back from the profile nose, so that the suction effect is developed before the commencement of the combing period and the fiber beard brought about by the suction effect from the beginning of the comb segment is recorded.

Die Erfindung wird anhand der Figur weiter veranschau­licht. Sie zeigt rein schematisch die Seitenansicht einer Kämmeinrichtung.The invention is further illustrated with the aid of the figure. It shows the side view of a combing device purely schematically.

Die Kämmeinrichtung weist einen Kämmzylinder 1 mit einem Zylinderkörper 2, der ein Kämmsegment 3 trägt, auf. Das Kämmsegment ist an seinem Anfang 4 und an seinem Ende 5 mit vier (nicht dargestellten) Befesti­gungsflanschen am Zylinderkörper 2 befestigt. Es weist eine stärker gekrümmte, mit Zähnen 6 besetzte Aussen­fläche 7 und eine weniger gekrümmte, dem Mantel 9 des Zylinderkörpers 2 zugewandte Innenfläche 8 auf. Die Innenfläche 8 und der Mantel 9 begrenzen einen sich auf das Ende 5 des Kämmsegmentes 3 zu erweiternden Luft­kanal. Diese beiden Flächen 8,9 sind glatt ausgebildet, um den Reibungswiderstand möglichst niedrig zu halten.The combing device has a combing cylinder 1 with a cylinder body 2 which carries a combing segment 3. The combing segment is fastened to the cylinder body 2 at its beginning 4 and at its end 5 with four fastening flanges (not shown). It has a more curved outer surface 7 with teeth 6 and a less curved inner surface 8 facing the jacket 9 of the cylinder body 2. The inner surface 8 and the jacket 9 delimit an air channel to be widened to the end 5 of the comb segment 3. These two surfaces 8, 9 are smooth in order to keep the frictional resistance as low as possible.

Bei Zylinderkörpern, die z.B. aus Wuchtgründen Ausneh­mungen aufweisen, kann die kontinuierliche, d.h. ge­schlossene glatte Mantelfläche durch Auflegen einer dünnen Folie auf die diskontinuierliche Mantelfläche erzielt werden. Die Grösse der Zähne 6 des Kämmseg­mentes 3 nimmt von dessen Anfang 4 auf dessen Ende 5 zu ab.For cylinder bodies, e.g. for reasons of balancing, the continuous, i.e. closed smooth outer surface can be achieved by placing a thin film on the discontinuous outer surface. The size of the teeth 6 of the combing segment 3 decreases from the beginning 4 to the end 5 thereof.

Oberhalb des Kämmzylinders 2 ist eine Zange 12 mit einer oberen und einer unteren Backe 14,15 angeordnet, die einen angelieferten Faserbart 13 festhalten. Ueber der unteren Backe 15 befindet sich eine Speisewalze 16.A pair of pliers 12 with an upper and a lower jaw 14, 15 are arranged above the combing cylinder 2 and hold a delivered fiber beard 13. A feed roller 16 is located above the lower jaw 15.

Im Anschluss an den Kämmzylinder 2 ist ein Fixkamm 17 angeordnet, auf den ein Abreisswalzenpaar 18 folgt.Following the combing cylinder 2, a fixed comb 17 is arranged, followed by a tear-off roller pair 18.

Im Betrieb wird eine bestimmte Menge eines Faserma­terials 19 von der Speisewalze 16 der Zange 12 zuge­liefert, die durch periodisches Oeffnen der Backen 14,15 den Faserbart 13 freigibt und danach einen neuen Faserbart festhält. Dieser Faserbart wird durch die Saugwirkung des erfindungsgemässen Kämmzylinders 2 an das sich nähernde, im Uhrzeigersinn drehende, Kämmseg­ment 3 herangeführt, wo er von den Zähnen 6 erfasst und durchgekämmt wird. Danach senkt sich der Fixkamm 17 und das Abreisswalzenpaar 18 erfasst den Faserbart 13, zieht ihn aus der geöffneten Zange 12 und reisst ihn ab. Dabei wird das ungekämmte Ende des Faserbartes am Fixkamm 17 ausgekämmt.In operation, a certain amount of fiber material 19 is supplied by the feed roller 16 to the tongs 12, which is caused by the periodic opening of the jaws 14, 15 releases the fiber beard 13 and then holds a new fiber beard. This fiber beard is guided by the suction effect of the combing cylinder 2 according to the invention to the approaching, clockwise rotating comb segment 3, where it is gripped by the teeth 6 and combed through. Then the fixed comb 17 lowers and the tear-off roller pair 18 grasps the fiber beard 13, pulls it out of the opened pliers 12 and tears it off. The uncombed end of the fiber beard on the fixed comb 17 is combed out.

Selbstverständlich sind weitere Ausführungsformen der Erfindung möglich. Beispielsweise kann das Kämmsegment über seine Länge gleich grosse Zähne in der Art eines Kardenbelages tragen. In diesem Fall ist die äussere, obere Profillinie des Kämmsegmentes ein Kreisbogen und die Ausgestaltung des Tragflügelprofils erfolgt allein durch die innere (untere) Profillinie. Letztere ist in jedem Fall weniger gekrümmt als die äussere Profillinie und kann sogar eine Gerade sein.Of course, further embodiments of the invention are possible. For example, the comb segment can have teeth of the same size over its length in the manner of a card covering. In this case, the outer, upper profile line of the comb segment is an arc and the wing profile is designed solely by the inner (lower) profile line. The latter is in any case less curved than the outer profile line and can even be a straight line.

Zur Verstärkung der aerodynamischen Wirkung kann am Ende des Kämmsegmentes ein Spoiler angeordnet werden.A spoiler can be arranged at the end of the comb segment to enhance the aerodynamic effect.

Durch den erfindungsgemässen Kämmzylinder wird die Wirksamkeit des Kämmverfahrens auch bei hohen Geschwin­digkeiten verbessert bzw. das Arbeiten bei erhöhter Geschwindigkeit unter Beibehaltung der bei niedrigen Geschwindigkeiten erzielten Kämmwirkung ermöglicht.The combing cylinder according to the invention improves the effectiveness of the combing process even at high speeds or enables working at increased speed while maintaining the combing effect achieved at low speeds.
