Description

Garnitur für eine Kämmwalze Garnitur für eine Kämmwalze für Textilmaschinen, insbesondere Kämm- Maschinen, umfassend eine Mehrzahl von in Drehrichtung der Kämmwalze gesehen hintereinander angeordneten Kämmsegmenten, wobei jedes Kämmsegment gebildet ist durch aufgereihte Sägezahnstanzteile mit einem Fußteil und sich vom Fußteil wegerstreckenden Zähnen, wobei sich die Konfiguration der Zähne der Garnitur in Drehrichtung gesehen ändert. Set for a combed roller Set for a combed roller for textile machines, in particular combing machines, comprising a plurality of comb segments arranged one behind the other in the direction of rotation of the combing roller, each comb segment being formed by rows of sawtooth punched parts with a foot part and teeth extending away from the foot part, whereby the Configuration of the teeth of the set changes in the direction of rotation.
Eine derartige gattungsgemäße Garnitur ist bekannt aus EP 0 179 158. Dort ist vorgesehen, innerhalb eines einzigen Sägezahnstanzteils die Spitzenkon- figuration so zu gestalten, daß die Spitzenhöhe, der Eingriffswinkel und der Spitzenabstand in Drehrichtung gesehen zunehmen. Durch die dementsprechend vorgesehene progressive Änderung wird ein schonendes Eindringen in das Faserband sowie dessen Auflockerung und Anhebung erreicht.Such a generic set is known from EP 0 179 158. There it is provided to design the tip configuration within a single sawtooth stamped part in such a way that the tip height, the pressure angle and the tip spacing increase when viewed in the direction of rotation. The progressive change accordingly provides for a gentle penetration into the sliver and its loosening and lifting.
Aus der DE 299 13 366 ist eine Garnitur bekannt, bei der das in Drehrichtung gesehen zuerst in das Faserband eingreifende Segment eine geringere Kämmwirkung hervorbringt als mindestens eines der das Faserband danach durchlaufenden Folgesegmente, wobei hierzu die Folgesegmente in Um- fangsrichtung eine größere Länge aufweisen als das vorderste Segment. Diese dementsprechende Dimensionierung der Erstreckung in Umfangs- richtung und eine progressiv sich ändernde Zahnhöhe oder Zahndichte allein genügen aber nicht, um optimale Kämmergebnisse zu erzielen.From DE 299 13 366 a set is known in which the segment which first intervenes in the sliver seen in the direction of rotation produces less combing effect than at least one of the following segments which then pass through the sliver, the subsequent segments having a greater length in the circumferential direction than this the foremost segment. However, this corresponding dimensioning of the extent in the circumferential direction and a progressively changing tooth height or tooth density alone are not sufficient to achieve optimal combing results.
Hiervon ausgehend liegt der Erfindung die Aufgabe zugrunde, eine gat- tungsgemäß als bekannt vorausgesetzte Garnitur noch weiter zu verbessern und das Kämmergebnis zu optimieren. Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Garnitur in ihrer Gesamtheit so ausgestaltet ist, daß die Parameter Zahnabstand und/oder Eingriffswinkel der jeweiligen Zahnflanke und/oder freier Durchgang zwischen den Zähnen und/oder Zahnhöhe sich an unterschiedlichen Winkelpositionen gesehen in Umfangsrichtung der Garnitur ändern.Proceeding from this, the object of the invention is to further improve a clothing which is known to be of the generic type and to optimize the combing result. This object is achieved in that the set is designed in its entirety so that the parameters tooth spacing and / or pressure angle of the respective tooth flank and / or free passage between the teeth and / or tooth height change seen at different angular positions in the circumferential direction of the set ,
Durch die erfindungsgemäße Ausgestaltung der Garnitur wird erreicht, daß die Auskämmung von Kurzfasern sanft gestaltet wird. Darüber hinaus wurde festgestellt, daß generell das Kämmergebnis gegenüber vergleichbaren Garnituren deutlich verbessert werden konnte. Die erfindungsgemäß vorgesehen relativ feine und differenzierte Strukturierung der Konfiguration erweist sich demnach als überraschend wirkungsvoll.The configuration of the clothing according to the invention ensures that the combing out of short fibers is designed gently. In addition, it was found that the combing result could generally be significantly improved compared to comparable sets. The relatively fine and differentiated structuring of the configuration provided according to the invention therefore proves to be surprisingly effective.
Nachfolgend wird die Erfindung anhand eines bevorzugten Ausführungs- beispiels in Verbindung mit der Zeichnung näher erläutert. Dabei zeigen:The invention is explained in more detail below on the basis of a preferred exemplary embodiment in conjunction with the drawing. Show:

Eine in der Zeichnung dargestellte Garnitur 1 für einen nicht dargestellten Kreiskamm umfaßt im Ausführungsbeispiel jeweils vier in Drehrichtung (Pfeil P) hintereinander angeordnete Riegel 2, 3, 4, 5 welche jeweils aus aufgereihten Sägezahnstanzteilen 6, 7, 8, 9 bestehen. Das Aufreihen und Halten der Sägezahnstanzteile 6, 7, 8, 9 wird durch schwalbenschwanzför- mige Nuten 10 und seitlich hiervon angeordnete Bohrungen 11 in bekannter Weise bewerkstelligt.A set 1 shown in the drawing for a circular comb, not shown, comprises in the exemplary embodiment four bars 2, 3, 4, 5 arranged one behind the other in the direction of rotation (arrow P), each of which consists of lined sawtooth punched parts 6, 7, 8, 9. The lining up and holding of the sawtooth punched parts 6, 7, 8, 9 is done by dovetail Mige grooves 10 and laterally arranged holes 11 accomplished in a known manner.
Jedes Sägezahnstanzteil 6, 7, 8, 9 umfaßt einen Fußbereich 12, in welchem die Ausnehmungen 10, 11 ausgebildet sind, und eine Mehrzahl sich von dem Fußbereich 12 in etwa radialer Richtung nach außen weg erstreckende Zähne 13.Each sawtooth stamped part 6, 7, 8, 9 comprises a base area 12, in which the recesses 10, 11 are formed, and a plurality of teeth 13 which extend outward from the base area 12 in an approximately radial direction.
Diese Zähne 13 sind in Drehrichtung (Pfeil P) geneigt und weisen eine vor- dere, zunächst in das Faserband eingreifende Flanke 14 und eine rückwärtige Flanke 15 auf.These teeth 13 are inclined in the direction of rotation (arrow P) and have a front flank 14 which initially engages in the fiber sliver and a rear flank 15.
Die Konfiguration dieser Zähne 13 relativ zu den jeweils davor und dahinter liegenden Zähnen ebenso wie relativ zu den in Richtung der Drehachse gesehen daneben liegenden Zähnen 13 läßt sich durch verschiedene Parameter beschreiben, welche in Verbindung mit Fig. 1 näher erläutert werden:The configuration of these teeth 13 relative to the teeth in front of and behind them as well as relative to the teeth 13 lying next to them in the direction of the axis of rotation can be described by various parameters, which are explained in more detail in connection with FIG. 1:
Ein erster derartiger Parameter ist der Eingriffswinkel E der Zahnbrust bzw. der vorderen Zahnflanke 14, d.h. der Winkel, den diese vordere Zahn- flanke 14 mit der radialen Richtung R einschließt. Dieser Parameter E ist in Fig. la veranschaulicht.A first such parameter is the pressure angle E of the tooth face or the front tooth flank 14, i.e. the angle that this front tooth flank 14 forms with the radial direction R. This parameter E is illustrated in Fig. La.
Ein weiterer Parameter, der in Fig. lb dargestellt ist, ist der freie Durchgang D zwischen zwei Zähnen 13 bzw. Sägezahnstanzteile 6, 7, 8, 9, die innerhalb ein und desselben Riegels 2, 3, 4, 5 nebeneinander liegen.Another parameter, which is shown in FIG. 1b, is the free passage D between two teeth 13 or sawtooth punched parts 6, 7, 8, 9, which lie next to one another within one and the same bolt 2, 3, 4, 5.
Der Abstand T zweier benachbarter Zähne in Kämmrichtung (Pfeil P) ist ein weiterer, in Fig. lc dargestellter Parameter. Letztlich ist in Fig. ld als letzter Parameter noch die Zahnhöhe H veranschaulicht. Die Zahnhöhe H wird gemessen zwischen der fiktiven Oberkante 16 des Fußbereiches 12 und der äußeren Hüllkurve 17 der Zahnspitzen 18.The distance T between two adjacent teeth in the combing direction (arrow P) is another parameter shown in FIG. 1c. Finally, the tooth height H is illustrated in FIG. 1d as the last parameter. The tooth height H is measured between the fictitious upper edge 16 of the foot region 12 and the outer envelope curve 17 of the tooth tips 18.
In Fig. 2 ist eine erste Ausführungsform einer erfindungsgemäßen Garnitur 1 dargestellt, wobei es sich jeweils bei einem der in Kämmrichtung (Pfeil P) nacheinander eingezeichneten Radien Rl bis R16 an jeweils unterschiedlichen Winkelpositionen ein Parameter, nämlich der Eingriffswinkel E, der freie Durchgang D, der Zahnabstand T und die Zahnhöhe H sich derart ändern, daß in Kämmrichtung gesehen die Zahnhöhe H zunimmt, der freie Durchgang D zunimmt, der Zahnabstand T zunimmt und der Eingriffswinkel E abnimmt. FIG. 2 shows a first embodiment of a clothing 1 according to the invention, one parameter, namely the pressure angle E, the free passage D, in each of one of the radii R1 to R16 drawn one after the other in the combing direction (arrow P) at different angular positions. the tooth spacing T and the tooth height H change such that the tooth height H increases in the combing direction, the free passage D increases, the tooth spacing T increases and the pressure angle E decreases.
