Abstract

Disclosed is a toothed edging for textile machines such as combing machines, drafting and opening cylinders for open-end devices and similar, comprising a plurality of bars formed by sawtooth stampings which are disposed next to each other in a parallel manner, are slid in a form-fitting manner onto a holding part by means of a recess that is located in the base area thereof, and are fixed in the longitudinal direction of the holding part by means of cheeks of the supporting segment or the cylinder when placed in the operating position. At least some sections of the recesses (7) of the inventive sawtooth stampings (1) and the cross sections of the holding part (6) are embodied in a T-shaped manner and have two peripheries (8, 10) which run approximately parallel to each other at least in some sections thereof.

Description

Zahnbesatz für Walzen und Tragsegmente von TextilmaschinenTooth trimming for rollers and supporting segments of textile machines

Die Erfindung richtet sich auf einen Zahnbesatz für Textilmaschinen, wie Kämm-Maschinen, Verzugs- und Aullösewalzen für Offenend- Vorrichtungen und dergleichen, bestehend aus einer Mehrzahl von Riegeln aus parallel nebeneinander angeordneten Sägezahnstanzteilen, welche mittels einer Ausnehmung in ihrem Fußbereich auf ein Halteteil formschlüssig aufgeschoben sind und in ihrer Gebrauchslage in Längsrichtung des Halteteils durch Wangen des Tragsegments oder der Walze festgehalten sind.The invention is directed to a tooth set for textile machines, such as combing machines, warping and unlocking rollers for open-end devices and the like, consisting of a plurality of bars made of sawtooth punched parts arranged in parallel next to one another, which are positively pushed onto a holding part by means of a recess in their foot region are and are held in their position of use in the longitudinal direction of the holding part by cheeks of the support segment or the roller.

Ein derartiger Zahnbesatz ist aus der DE 30 07 245 C2 bekannt, wobei das Halteteil im Querschnitt entweder schwalbenschwanzförmig oder annähernd rechteckig mit kreisabschnittförmigen Seitenteilen ausgebildet ist.Such tooth trimming is known from DE 30 07 245 C2, the holding part being designed in cross section either in the form of a dovetail or approximately rectangular with side parts in the form of circular sections.

Diese Art der Befestigung hat sich in der Praxis außerordentlich gut bewährt, wobei allerdings die seitlichen Teilflächen bzw. Kreissegmente zu Toleranzen bei der Positionierung der zu kämmenden Spitzen führen. Ähnliches gilt für eine Befestigung, wie sie aus der EP 0 839 934 AI bekannt ist.This type of attachment has proven itself extremely well in practice, although the lateral partial surfaces or circular segments lead to tolerances in the positioning of the tips to be combed. The same applies to a fastening, as is known from EP 0 839 934 AI.

Da Versuche gezeigt haben, dass eine exakt einheitliche Position der Spitzen der Kämmsegmente für die Erzielung eines optimalen Kämm- Ergebnisses von herausragender Bedeutung ist, liegt der Erfindung die Aufgabe zu Grunde, die Geometrie der Befestigung so zu verbessern, dass die Toleranzen erheblich reduziert werden. Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass die Ausnehmungen der Sägezahnstanzteile und der Querschnitt des Halteteils wenigstens abschnittsweise T-förmig mit zwei wenigstens abschnittsweise etwa parallel zueinander verlaufenden Begrenzungsflächen ausgebildet sind.Since tests have shown that an exactly uniform position of the tips of the combing segments is of outstanding importance for achieving an optimal combing result, the object of the invention is to improve the geometry of the fastening in such a way that the tolerances are considerably reduced. This object is achieved according to the invention in that the recesses of the sawtooth stamped parts and the cross section of the holding part are at least sectionally T-shaped with two delimiting surfaces running at least in sections approximately parallel to one another.

Die erfindungsgemäß vorgesehene T-fÖrmige Konfiguration, d. h. eine Konfiguration mit zwei zueinander parallelen Abschnitten, sorgt dafür, dass die Toleranzen in radialer Richtung, d.h. in derjenigen Richtung, die für die Höhenlage der Spitzen bzw. den radialen Abstand von der Drehachse verantwortlich ist, minimiert werden. Versuche haben gezeigt, dass eine Reduzierung der Toleranzen gegenüber Ausgestaltungen nach dem Stand der Technik auf die Hälfte möglich ist, wodurch das Kämm-Ergebnis verbessert wird.The T-shaped configuration provided according to the invention, i. H. a configuration with two mutually parallel sections ensures that the tolerances in the radial direction, i.e. in the direction that is responsible for the height of the tips or the radial distance from the axis of rotation, are minimized. Tests have shown that it is possible to reduce the tolerances compared to configurations according to the prior art by half, which improves the combing result.

Die erfindungsgemäße Ausgestaltung ermöglicht eine kostengünstige einteilige Realisierung der Sägezahnsegmente und eine exakte, ausschließlich formschlüssige Positionierung, ohne dass eine zusätzliche Federbeaufschlagung erforderlich wäre.The configuration according to the invention enables a cost-effective, one-piece realization of the sawtooth segments and an exact, exclusively form-fitting positioning, without additional spring loading being necessary.

Nachfolgend wird die Erfindung anhand eines bevorzugten Ausführungsbeispiels in Verbindung mit der Zeichnung näher erläutert. Diese zeigt eine schematische Darstellung eines erfindungsgemäßen Zahnbesatzes.The invention is explained in more detail below on the basis of a preferred exemplary embodiment in conjunction with the drawing. This shows a schematic representation of a tooth set according to the invention.

In der Zeichnung ist ein vollständiges Sägezahnstanzteil 1 dargestellt, welches einen Fußbereich 2 und eine Mehrzahl von Zähnen 3 aufweist. Rechts in der Zeichnung sind weitere Zähne 3 von dahinterliegenden Säge- zahnstanzteilen 1 angedeutet, welche über Ausnehmungen 4 und in der Zeichnung nicht dargestellte Verbindungsstäbe einen Riegel 5 ausbilden. Die Befestigung dieser Sägezahnstanzteile 1 bzw. einer Mehrzahl von Riegeln 5 an der Kämmwalze einer Kämm-Maschine ist in DE 30 07 245 AI im Einzelnen beschrieben, insbesondere auch die Funktion eines Halte- teils 6.In the drawing, a complete sawtooth stamped part 1 is shown, which has a base area 2 and a plurality of teeth 3. On the right in the drawing, further teeth 3 are indicated by sawtooth stamping parts 1 lying behind them, which form a bolt 5 via recesses 4 and connecting rods (not shown in the drawing). The attachment of these sawtooth punched parts 1 or a plurality of bars 5 to the combing roller of a combing machine is described in detail in DE 30 07 245 AI, in particular also the function of a holding part 6.

Jedes Sägezahnstanzteil 1 weist eine Ausnehmung 7 auf, um die Sägezahnstanzteile 1 bzw. die durch eine Mehrzahl solcher Sägezahnstanzteile 1 gebildeten Riegel 5 auf den Befestigungsabschnitt 8 des Halteteils 6 auf- zuschieben.Each sawtooth punched part 1 has a recess 7 in order to push the sawtooth punched parts 1 or the bars 5 formed by a plurality of such sawtooth punched parts 1 onto the fastening section 8 of the holding part 6.

Der Befestigungsabschnitt 8 des Halteteils 6 weist eine im Querschnitt T-förmige Konfiguration auf, d. h. zwei bezogen auf die Kämmwalze annähernd tangential und parallel zueinander verlaufende Flächen 9, 10 und zwei bezogen auf die Kärnmwalze annähernd radial und parallel zueinander verlaufende Begrenzungsflächen 11.The fastening section 8 of the holding part 6 has a configuration with a T-shaped cross section, i. H. two surfaces 9, 10 which are approximately tangential and parallel to one another with respect to the combing roller and two boundary surfaces 11 which run approximately radially and parallel to one another with respect to the comb roller.

Im Vergleich zu einer herkömmlicher Weise verwendeten schwalben- schwanzförmigen Konfiguration werden hierdurch wesentlich geringere Toleranzen in radialer Richtung (Radius R) erzielt, so dass die Zähne 3 der Sägezahnstanzteile 1 exakt und gleichmäßiger positioniert sind, wodurch ein verbessertes Kämmergebnis erzielt wird. Compared to a dovetail configuration used in a conventional manner, this results in much smaller tolerances in the radial direction (radius R), so that the teeth 3 of the sawtooth stamped parts 1 are positioned exactly and more uniformly, thereby achieving an improved combing result.
