Abstract

A combing machine comprises a rotating combing roller with a comb segment, a feed device for a sliver to be combed, a gripper arrangement disposed in the vicinity of the comb segment which opens and closes in a manner coordinated with the passing movement of the comb segment and which holds the sliver while the latter is being combed by the comb segment, and a draw-off device which moves the combed sliver away. For reducing the mass to be moved and for the improvement of the combing quality a transfer gripper arrangement (14) is provided which is movable back and forth between the gripper arrangement (1) and the draw-off device (2) in a manner coordinated with the rotating motion of the comb segment (8) and which, after passage of the comb segment (8) and combing of the protruding tuft (22) and the opening of the gripper arrangement (1), grips the combed sliver (22) and holds it in such a way that during the next pass of the comb segment (8) the rear portion of the sliver (22a), looking in the direction of movement, is combed by the comb segment (8), and which then hands off the sliver 922) to the draw-off device (2).

Description

Die Erfindung richtet sich auf eine Kämmaschine umfas­send eine rotierende Kämmwalze mit einem Kämmsegment, eine Zuführeinrichtung für ein Band zu kämmender Fa­sern, eine im Bereich des Kämmsegments angeordnete, sich koordiniert mit der Vorbeibewegung des Kämmseg­ments öffnende und schließende, das Faserband während des Kämmens durch das Kämmsegment festhaltende Zangen­anordnung sowie eine das gekämmte Faserband abtrans­portierende Abzugseinrichtung.The invention is directed to a combing machine comprising a rotating combing roller with a combing segment, a feed device for a band of fibers to be combed, a fiber arranged in the region of the combing segment, opening and closing coordinated with the moving of the combing segment, the fiber band during the combing through the combing segment holding pliers arrangement as well as a pull-off device that transports the combed sliver.

Derartige Kämmaschinen dienen dazu, Baumwollfasern oder Wollfasern von darin enthaltenen natürlichen Ver­unreinigungen zu befreien und die Fasern des Faserban­des zu parallelisieren. Zu diesem Zweck wird ein vor­bereitetes Faserband zwischen den Backen der Zangenan­ordnung derart verklemmt, daß eine bestimmte Teillänge der Fasern an der Vorderseite der Backen als sogenann­ter Faserbart übersteht. Mittels des mit einer Nadel- oder Zahngarnitur besetzten Kämmsegmentes der Kämmwal­ze wird dieser Faserbart gekämmt und damit gereinigt. Die Abzugseinrichtung besteht in der Regel aus zwei gegensinnig rotierenden Walzen, welche den gekämmten Faserbart erfassen und weitertransportieren.Such combing machines are used to free cotton fibers or wool fibers from the natural impurities contained therein and to parallelize the fibers of the sliver. For this purpose, a prepared sliver is clamped between the jaws of the pliers arrangement in such a way that a certain partial length the fibers on the front of the jaws survive as a so-called fiber beard. By means of the combing segment of the combing roller, which is equipped with a needle or tooth set, this fiber beard is combed and thus cleaned. The take-off device generally consists of two rollers rotating in opposite directions, which grasp the combed fiber beard and transport it further.

Um die teilweise gereinigten Fasern mit den Walzen der Abzugseinrichtung aus den Backen der Zangeneinheit ab­ziehen zu können, muß sich entweder die relativ schwe­re Abzugseinrichtung linear oder in einem Kreisbogen­abschnitt zu dem zwischen den Backen der Zangenanord­nung gehaltenen Faserbart bewegen, oder umgekehrt muß die Zangenanordnung auf die stationären Abzugswalzen zubewegt werden. Dies führt bei den üblicherweise er­forderlichen 200 bis 350 Kammspielen pro Minute ange­sichts der großen bewegten Massen zu einer hohen dyna­mischen Unruhe der gesamten Kämmaschine und begrenzt deren Arbeitsgeschwindigkeit.In order to be able to pull the partially cleaned fibers out of the jaws of the pliers unit with the rollers of the pull-off device, either the relatively heavy pull-off device must move linearly or in a circular arc section to the fiber beard held between the jaws of the plier arrangement, or vice versa, the pliers arrangement must move onto the stationary ones Pull rollers are moved. Given the 200 to 350 comb cycles per minute that are usually required, this leads to a high dynamic unrest of the entire combing machine in view of the large moving masses and limits its working speed.

Darüber hinaus besteht bei herkömmlichen Kämmaschinen das Problem, daß wenn die gekämmten Fasern durch die sich gegenläufig drehenden Abzugswalzen abgezogen wer­den, bis zu 50 % der Faserlänge nicht durch den Kreis­kamm gereinigt wurde, weil sie während des Kämmprozes­ses, also beim Passieren des Kämmsegments, zwischen den Backen der Zangenanordnung verklemmt ware oder sich in Transportrichtung gesehen hinter den Backen befand. Um auch diesen Teil der Fasern so gut wie möglich zu reinigen, werden herkömmlicherweise diese Fasern durch einen vor den Abzugswalzen angeordneten Fixkamm gezogen. Ein solcher aus einer oder allenfalls zwei Nadelreihen bestehender Fixkamm kann aber natur­gemäß nicht die Reinigungswirkung eines mit tausenden von Spitzen besetzten Kammsegments aufweisen.In addition, there is the problem with conventional combing machines that when the combed fibers are drawn off by the counter-rotating drawing rollers, up to 50% of the fiber length has not been cleaned by the circular comb, because during the combing process, that is to say when passing through the combing segment, between the The jaws of the pliers arrangement were jammed or were located behind the jaws as seen in the transport direction. In order to clean this part of the fibers as well as possible, they are conventionally used Fibers pulled through a fixed comb arranged in front of the take-off rollers. Such a fixed comb consisting of one or at most two rows of needles naturally cannot have the cleaning effect of a comb segment filled with thousands of tips.

Hiervon ausgehend liegt der Erfindung die Aufgabe zu­grunde, einerseits durch eine Verminderung der während des Kämmvorgangs bewegten Massen die dynamischen Bela­stungen zu reduzieren und andererseits dafür zu sor­gen, daß der Teil des Faserbandes, der bisher durch den Fixkamm nur unzureichend gekämmt wurde, ebenfalls einer intensiven Reinigung durch den Kreiskamm unter­zogen wird.Proceeding from this, the object of the invention is, on the one hand, to reduce the dynamic loads by reducing the masses moved during the combing process and, on the other hand, to ensure that the part of the sliver which was previously inadequately combed by the fixed comb also undergoes intensive cleaning through the circular crest.

Diese Aufgabe wird erfindungsgemäß gelöst durch eine zwischen der Zangenanordnung und der Abzugseinrichtung Koordiniert mit der Drehbewegung des Kämmsegments hin- und herbewegbare Transferzangenanordnung, welche nach dem Passieren des Kämmsegments und dem Kämmen des vor­stehenden Faserbandes und dem Öffnen derzangenanord­nung das gekämmte Faserband erfaßt und derart hält, daß beim nächsten Passieren des Kämmsegments nun der in Transportrichtung gesehen rückwärtige Teil des Fa­serbandes durch das Kämmsegment gekämmt wird, und das Faserband dann an die Abzugseinrichtung weitergibt.This object is achieved according to the invention by a transfer pliers arrangement which can be moved back and forth between the pliers arrangement and the take-off device and which, after passing through the comb segment and combing the protruding sliver and opening the pliers arrangement, detects and holds the combed sliver and holds it in such a way that the next time the combing segment passes, the rear part of the sliver, as seen in the transport direction, is combed by the combing segment, and the sliver is then passed on to the take-off device.

Eine derartige Transferzangenanordnung kann wesentlich leichter ausgebildet werden, als die herkömmlicherwei­se bewegte Zangenanordnung. So kann deren Gewicht etwa nur ein Zehntel einer solchen herkömmlichen Zangenan­ ordnung betragen. Die Transferzange übernimmt also eine Übertragungsfunktion für den gekämmten Teil des Faserbandes von der herkömmlichen Zangenanordnung zu den herkömmlichen Abzugswalzen, was dazu führt, daß diese beiden Anordnungen selbst ortsfest ausgebildet werden können und die dynamischen Probleme bei der Be­schleunigung und dem Abbremsen dieser relativ hohen Massen vermieden werden. Vor allem aber wird durch die erfindungsgemäße Ausgestaltung erreicht, daß die Kämm­qualität ganz erheblich verbessert wird, weil der bis­her nicht gekämmte Teil des Faserbandes nun auch durch den rotierenden Kreiskamm gekämmt wird, dessen Kämm­wirkung natürlich erheblich besser ist als diejenige der herkömmlicherweise verwendeten, ortsfesten Fixkäm­me. Dabei ist für die Realisierung dieser zusätzlichen Kämmwirkung kein zusätzliches Kammsegment oder eine sonstige Kämmeinrichtung erforderlich, sondern ein und dasselbe Kämmsegment wird lediglich über einen größe­ren Teil seiner Umlaufbahn genutzt, indem es bei jedem Umlauf zunächst den in Transportrichtung gesehenen vorderen Teil des Faserbandes und unmittelbar an­schließend den rückwärtigen Teil des Faserbandes kämmt, dessen Vorderseite beim vorhergehenden Passie­ren des Kämmsegmentes gekämmt wurde.Such a transfer tong arrangement can be made much lighter than the conventionally moved tong arrangement. So their weight can only about a tenth of such conventional pliers order. The transfer pliers thus take over a transfer function for the combed part of the sliver from the conventional pliers arrangement to the conventional take-off rollers, which means that these two arrangements can be designed to be stationary and the dynamic problems in accelerating and braking these relatively high masses are avoided . Above all, however, it is achieved by the configuration according to the invention that the combing quality is improved considerably because the previously uncombed part of the sliver is now also combed by the rotating circular comb, the combing action of which is of course considerably better than that of the conventionally used, fixed fixed combs. No additional comb segment or other combing device is required for the realization of this additional combing effect, but one and the same combing segment is only used over a larger part of its orbit, by firstly moving the front part of the sliver seen in the transport direction and immediately afterwards in each circulation combs the rear part of the sliver, the front of which was combed during the previous passage through the comb segment.

Die Transferzangenanordnung kann linear beweglich ge­lagert sein. Vorzugsweise ist sie zwischen der Zangen­anordnung und der Abzugseinrichtung schwenkbar gela­gert. Dabei kann die Öffnungs- und Schließbewegung der Backen der Transferzangenanordnung von deren Schwenk­bewegung abgeleitet sein. Die Schwenkbewegung kann ihrerseits wieder von der Drehbewegung des Kämmseg­ments abgeleitet werden.The transfer tongs arrangement can be mounted to be linearly movable. It is preferably pivotally mounted between the pliers arrangement and the trigger device. The opening and closing movement of the jaws of the transfer pliers arrangement can be derived from their pivoting movement. The swiveling movement can in turn can be derived from the rotary movement of the comb segment.

Hierdurch sind für die Bewegung der Transferzangenan­ordnung und deren Öffnungsbewegung keine gesonderten Antriebsmechanismen erforderlich und es ist auf mecha­nische Weise eine Bewegungskoordination mit der Dreh­bewegung des Kämmsegments gewährleistet.As a result, no separate drive mechanisms are required for the movement of the transfer tong arrangement and its opening movement, and mechanical coordination of the movement with the rotary movement of the comb segment is ensured.

Bei einer abgewandelten Ausführungsform ist vorgese­hen, daß in einer ersten Backe der Transferzangenan­ordnung wenigstens eine vorstehende Nadelreihe ange­ordnet ist, welche in eine Ausnehmung der jeweils an­deren Backe beim Schließen der Zangenanordnung ein­greift. Hierdurch wird eine Parallelisierungswirkung und eine nochmalige Kämmwirkung nach Art eines Fixkam­mes beim Herausziehen des Faserbandes durch die Ab­zugswalzen erreicht.In a modified embodiment it is provided that at least one protruding row of needles is arranged in a first jaw of the transfer pliers arrangement and engages in a recess of the other jaw when the pliers arrangement is closed. In this way, a paralleling effect and a renewed combing effect in the manner of a fixed comb is achieved when the sliver is pulled out by the take-off rollers.

Dabei ist günstigerweise vorgesehen, daß die Backen der Transferzangenanordnung im Querschnitt nasenförmi­ge Vorsprünge aufweisen, an welchen die eigentliche Haltekante ausgebildet ist.It is advantageously provided that the jaws of the transfer pliers arrangement have nose-shaped projections in cross section, on which the actual holding edge is formed.

Bei einer alternative Ausführungsform ist vorgesehen, daß die Transferzangenanordnung zwei aneinander anlie­gende, gegensinnig angetriebene Transportwalzen um­faßt, wobei die Öffnungsbewegung der Transferzangenan­ordnung durch den Transportzustand der Walzen und die Schließbewegung durch den Schließzustand der Walzen realisiert wird.In an alternative embodiment it is provided that the transfer tongs arrangement comprises two transport rollers which are driven in opposite directions, the opening movement of the transfer tongs arrangement being realized by the transport state of the rollers and the closing movement by the closed state of the rollers.

Günstigerweise sind die Walzen durch Federanordnungen gegeneinander federnd angedrückt, um im Augenblick des Kämmens des rückwärtigen Teils des Faserbandes eine hinreichende Haltewirkung zu erzielen.Conveniently, the rollers are resiliently pressed against one another by spring arrangements in order to achieve a sufficient holding effect at the moment of combing the rear part of the sliver.

Kämmaschinen der in Betracht stehenden Art sind z. B. aus der DE-OS 28 45 245 und den dortgenannten Veröf­fentlichungen bekannt. Die erfindungsgemäße, nachfol­gend beschriebene Kämmaschine unterscheidet sich hier­von jedoch wesentlich dadurch, daß sowohl die Zangen­ anordnung 1 als auch die Abzugseinrichtung 2 stationär angeordnet sind.Combing machines of the type in question are e.g. B. from DE-OS 28 45 245 and the publications mentioned there. The combing machine according to the invention, described below, differs essentially from this in that both the pliers arrangement 1 and the trigger device 2 are arranged stationary.

Eine erfindungsgemäße Kämmaschine umfaßt also eine Zangenanordnung 1 mit einer feststehenden Unterzange 3 und einer um einen Schwenklagerpunkt 4 schwenkbar an­geordneten Oberzangen 5.A combing machine according to the invention thus comprises a pair of pliers 1 with fixed lower pliers 3 and upper pliers 5 pivotably arranged about a pivot bearing point 4.

Unterhalb der Zangenanordnung 1 ist ein Kreiskamm 6 umfassend eine Kämmwalze 7 und ein an dieser angeord­netes Kämmsegment 8 vorgesehen, wobei der Kreiskamm 6 um eine Drehachse 9 drehangetrieben ist. Das Kämmseg­ment 8 ist mit einer Garnitur, im Ausführungsbeispiel einer Sägezahngarnitur 10 versehen.Provided below the pliers arrangement 1 is a circular comb 6 comprising a combing roller 7 and a comb segment 8 arranged thereon, the circular comb 6 being driven in rotation about an axis of rotation 9. The combing segment 8 is provided with a set, in the exemplary embodiment a sawtooth set 10.

Der Zangenanordnung 1 wird ein Faserband 11 aus zu Kämmenden Fasern in an sich bekannter Weise durch eine im einzelnen nicht dargestellte Zuführeinrichtung zu­geführt. Die Abführeinrichtung 2 umfaßt zwei Abzugs­walzen 12, welche in Richtung der Pfeile 13 in entge­gengesetzte Richtung drehangetrieben sind.The tongs arrangement 1 is fed a sliver 11 of fibers to be combed in a manner known per se by a feed device, not shown in detail. The discharge device 2 comprises two take-off rollers 12 which are driven in rotation in the direction of the arrows 13 in the opposite direction.

Zwischen der Zangenanordnung 1 und der Abzugseinrich­tung 2 ist eine Transferzangenanordnung 14 vorgesehen, welche um eine Schwenklagerachse 15 an einer Welle 16 schwenkbar gelagert ist.A transfer tong arrangement 14 is provided between the tong arrangement 1 and the trigger device 2, which is pivotably mounted on a shaft 16 about a pivot bearing axis 15.

Die Transferzangenanordnung umfaßt einen oberen Backen 17 und einen unteren Backen 18, wobei in dem oberen Backen 17 eine Nadelreihe 19 befestigt ist, deren Na­delspitzen 20 in eine Ausnehmung 21 an dem Backen 18 eingreifen. Die in der Zeichnung dargestellte Kämm­maschine arbeitet in an sich bekannter Weise so, daß die Zangenanordnung 1 schließt und das Faserband 11 festhält und dabei einen zu kämmenden Faserbart 22 vorstehen läßt, wenn das Kämmsegment 8 mit der Gar­nitur 10 passiert, so daß der Faserbart 22 gekämmt wird. Anschließend öffnet die Zangenanordnung 1 und das gekämmte Faserband bzw. der vorstehende Faserbart 22 können weitertransportiert werden.The transfer pliers arrangement comprises an upper jaw 17 and a lower jaw 18, a row of needles 19 being fastened in the upper jaw 17, the needle tips 20 of which in a recess 21 on the jaw 18 intervention. The comber shown in the drawing works in a manner known per se so that the pliers assembly 1 closes and holds the sliver 11 and thereby protrudes a fiber beard 22 to be combed when the combing segment 8 passes with the clothing 10 so that the fiber beard 22 is combed becomes. Then the pliers arrangement 1 opens and the combed sliver or the above fiber beard 22 can be transported further.

Die Besonderheit bei der erfindungsgemäßen Ausgestal­tung liegt in der danach vorgesehenen Transferzangen­anordnung 14.The special feature of the configuration according to the invention lies in the transfer tongs arrangement 14 provided thereafter.

Die Arbeitsweise dieser Transferzangenanordnung 14 wird aus dem Vergleich der Figuren 1 bis 4 deutlich. In Fig. 1 ist eine Bewegungsphase dargestellt, in wel­cher das in Richtung des Pfeils 23 sich drehende Kämm­segment 8 den Faserbart 22 passiert und gekämmt hat. Die Zangenanordnung 14 hat hierauf mit den Backen 17 und 18 den Faserbart 22 erfaßt und führt um die Schwenkachse 15 eine Schwenkbewegung in Richtung des Pfeils 24 aus. In dieser Position steht der bereits gekämmte Faserbart 22, wie in Figur 2 dargestellt, nach oben, während der nicht gekämmte Teil des Faser­bartes 22a, der zuvor von der Zangenanordnung 1 gehal­ten wurde, nun nach unten in den Bewegungsweg der Gar­nitur 10 des Kämmsegments 8 ragt. Wenn dementsprechend das Kämmsegment 8 nun passiert, wird zunächst der nachgeschobene, von der Zangenanordnung 1 zwischen Oberzange 5 und Oberzange 3 festgehaltene neue Faser­ bart 22b gekämmt und unmittelbar anschließend der un­gekämmte Teil 22a des vorher gekämmten Faserbandab­schnitts.The mode of operation of this transfer tong arrangement 14 is clear from the comparison of FIGS. 1 to 4. 1 shows a movement phase in which the comb segment 8 rotating in the direction of arrow 23 has passed and combed the fiber beard 22. The pliers arrangement 14 has then gripped the fiber beard 22 with the jaws 17 and 18 and performs a pivoting movement about the pivot axis 15 in the direction of the arrow 24. In this position, the already combed fiber beard 22, as shown in FIG. 2, stands upwards, while the non-combed part of the fiber beard 22a, which was previously held by the pliers arrangement 1, now projects downward into the path of movement of the clothing 10 of the comb segment 8 . Accordingly, when the combing segment 8 now passes, the new fiber, which is held in place by the pliers arrangement 1 between the upper pliers 5 and the upper pliers 3, first becomes beard 22b combed and immediately thereafter the uncombed part 22a of the previously combed sliver section.

Wie aus Figur 3 deutlich wird, bewegt sich dann die Transferzangenanordnung 14 in Richtung des Pfeils 25 noch ein Stück weiter um die Schwenkachse 15, so daß der Faserbart 22 von den Abzugswalzen 12 erfaßt werden und abgezogen werden kann. Um ein Abziehen des Faser­bartes 22 zu ermöglichen, öffnet die Transferzangenan­ordnung 14, d. h. die in Figur 3 untere Backe 10 ent­fernt sich von der oberen Backe 17.As is clear from FIG. 3, the transfer pliers arrangement 14 then moves a little further in the direction of the arrow 25 about the pivot axis 15, so that the fiber beard 22 can be gripped by the take-off rollers 12 and can be removed. In order to allow pulling the fiber beard 22, the transfer pliers arrangement 14, i. H. the lower jaw 10 in FIG. 3 moves away from the upper jaw 17.

Anschließend schwingt die Zangenanordnung 14, wie in Figur 4 dargestellt, in Richtung des Pfeils 26 um die Schwenkachse 15 im geöffneten Zustand zurück und er­faßt den Faserbart 22b, welcher noch zwischen Unter­zange 3 und Oberzange 5 der Zangenanordnung 1 gehalten wird, welche anschließend öffnet, so daß sich das Kämmspiel mit der in Figur 1 dargestellten Position wiederholt.Then, as shown in FIG. 4, the pliers arrangement 14 swings back in the direction of arrow 26 about the pivot axis 15 in the open state and grasps the fiber beard 22b, which is still held between lower pliers 3 and upper pliers 5 of the pliers arrangement 1, which then opens that the combing play is repeated with the position shown in Figure 1.

In Figur 5 und 6 sind die Backen 17, 18 der Transfer­zangenanordnung 14 näher dargestellt. Bei dieser Aus­führungsform sind in der oberen Backe 17a zwei Nadel­reihen 19 vorgesehen, welche im Schließzustand in kor­respondierende Ausnehmungen 20 eingreifen. Die Backen 17, 18 weisen nasenartige Vorsprünge 27, 28 auf, zwi­schen welchen eine Haltekante für das Faserband ausge­bildet ist. Eine in einer Ausnehmung 29 angeordnete Schraubenfeder 30 drückt die Backen 17, 18 auseinander und sorgt so für die Öffnungsbewegung. Die Schließbe­wegung wird über einen nicht dargestellten Nockenan­trieb von der Schwenkbewegung abgeleitet.5 and 6, the jaws 17, 18 of the transfer tong arrangement 14 are shown in more detail. In this embodiment, two rows of needles 19 are provided in the upper jaw 17a, which engage in corresponding recesses 20 in the closed state. The jaws 17, 18 have nose-like projections 27, 28, between which a retaining edge for the sliver is formed. A helical spring 30 arranged in a recess 29 presses the jaws 17, 18 apart and thus ensures the opening movement. The closing movement is derived from the pivoting movement via a cam drive, not shown.

In Figur 7 und 8 ist eine abgewandelte Ausführungsform der Backen der Transferanordnung 14 dargestellt. Die Backen sind bei dieser Ausführungsform durch Rollen 31 gebildet, welche in Richtung der Pfeile 32 in entge­gengesetzte Richtung drehantreibbar sind. In Figur 8 ist dargestellt, wie die Rollen 31 in Lagerteilen 33 über Lagerabschnitt 34 gelagert sind. Die Antriebsbe­wegung der Walzen 31 ist so gesteuert, daß sie still stehen, wenn zwischen ihnen ein Faserband festgehalten werden soll entsprechend dem Schließzustand der Backen 17, 18, wohingegen sie in Richtung der Pfeile 32 dreh­angetrieben sind, wenn die Zangenanordnung 14 einen "geöffneten" Zustand einnehmen soll, wobei dann der zwischen den Rollen 31 befindliche Teil des Faserban­des weitertransportiert wird.FIGS. 7 and 8 show a modified embodiment of the jaws of the transfer arrangement 14. In this embodiment, the jaws are formed by rollers 31 which can be driven in the opposite direction in the direction of the arrows 32. FIG. 8 shows how the rollers 31 are mounted in bearing parts 33 via bearing section 34. The drive movement of the rollers 31 is controlled so that they stand still when a sliver is to be held between them according to the closed state of the jaws 17, 18, whereas they are driven in the direction of arrows 32 when the pliers assembly 14 is in an "open" state Should take, then the part of the sliver located between the rollers 31 is transported further.
