Abstract

The present invention relates to an all-steel card clothing for rollers and/or cylinders of carding machines. Carding machines comprise rollers which are configured to actively take over raw fiber materials from rollers arranged upstream in work direction. Therefore, such card clothings have a relatively large front angle. The problem is that the stability of the card clothings suffers. According to the invention, the teeth have a head angle of >85° in order to solve this problem. The length of the head surface extending at said angle from the tooth tip to the tooth back corresponds to at least ¼ of the length of the tooth pitch. This achieves a considerably more stable card clothing while maintaining the high carding quality.

Description

Die Erfindung bezieht sich auf Ganzstahlgarnituren für Walzen und/oder Trommeln von Reinigern, Karden oder Krempeln, welche Walzen oder Trommeln eine höhere Umfangsgeschwindigkeit als in Faserfließrichtung jeweils vorgelagerte Walzen aufweisen, wobei die Ganzstahlgarnitur Zähne mit einem positiven Brustwinkel von ≥ 0° aufweist, siehe z.B. EP 1 099 783.The invention relates to all-steel sets for rolls and / or drums of cleaners, carding or carding, which rollers or drums have a higher peripheral speed than upstream in the fiber flow direction, the all-steel set having teeth with a positive breast angle of ≥ 0 °, see, e.g. EP 1 099 783.

Bei den hier betroffenen Walzen handelt es sich beispielsweise um Vorreißerwalzen, Wenderwalzen oder Übertragerwalzen an Karden oder Krempeln, sowie die Trommel einer Karde bzw. Krempel. Diese Walzen bzw. Trommeln übernehmen Faserrohstoff aktiv mit der Vorderkante des Brustwinkels der Zähne der entsprechenden Ganzstahlgarnitur.The rolls involved here are, for example, lickerin rolls, turning rolls or transfer rolls on carding machines or carding machines, as well as the drum of a carding machine or carding machine. These rolls or drums actively take fiber raw material with the front edge of the breast angle of the teeth of the corresponding all-steel set.

Das Problem bei diesen Garnituren ist, dass positive Brustwinkel benötigt werden, um eine gute Faserübernahme zu gewährleisten. Dadurch wird allerdings tendenziell die Zahnspitze schlanker, was diese Garnituren bei der Montage und auch beim Nachschärfen empfindlicher macht. Zudem können leichter Verunreinigungen oder Verschmutzungen im Faserrohstoff aufgespießt werden.The problem with these trimmings is that positive breast angles are needed to ensure good fiber take-up. As a result, however, the tip of the tooth tends to be slimmer, which makes these trimmings more sensitive during assembly and also during re-sharpening. In addition, it is easier to impale impurities or soiling in the fiber raw material.

Demzufolge liegt der Erfindung die Aufgabe zugrunde, eine Ganzstahlgarnitur der eingangs genannten Art zur Verfügung zu stellen, die unter Beibehaltung guter Übernahmeeigenschaften die im Stand der Technik zu beobachtenden Nachteile beseitigt.Accordingly, the invention has for its object to provide an all-steel set of the type mentioned above, which eliminates the disadvantages to be observed in the prior art while maintaining good takeover properties.

Diese Aufgabe wird bei einer Ganzstahlgarnitur der eingangs genannten Art dadurch gelöst, dass die Zähne einen Kopfwinkel aufweisen, der > 85°, vorzugsweise > 87° ist, wobei die Länge der sich unter diesem Winkel von der Zahnspitze bis zum Zahnrücken erstreckenden Kopffläche mindestens 15% der Länge der Zahnteilung entspricht.This object is achieved with an all-steel set of the type mentioned above in that the teeth have a head angle which is> 85 °, preferably> 87 °, the length of at this angle extending from the tooth tip to the back of the tooth head at least 15% the length of the tooth pitch corresponds.

Die sich aus dieser Zahnform ergebenden Vorteile sind, dass einerseits ein Zusetzen der Garnituren verhindert wird und dass die Garnitur zwar nach wie vor die für das Kardieren notwendige Agressivität oder Aktivität aufweist, gegenüber Verunreinigung aber stumpf wirkt. Ferner sind die Zähne der Ganzstahlgarnitur stabiler, weniger empfindlich bei der Montage und beim Nachschärfen. Darüber hinaus wird bei verunreinigten Faserrohstoffen wie beispielsweise Baumwolle das Aufspießen von Fremdteilen verhindert. Dadurch muß die Garnitur weniger häufig gereinigt werden. Insgesamt hat sich gezeigt, dass neben den zu erwartenden Vorteilen aber auch die Kardierqualität besser wird.The resulting from this tooth shape advantages are that on the one hand clogging of the sets is prevented and that the garnish while still has the necessary for the carding aggressiveness or activity, but dull acts against contamination. Furthermore, the teeth of the all-steel garnish are more stable, less sensitive during assembly and re-sharpening. In addition, contaminated fiber raw materials such as cotton, the imposition of foreign parts is prevented. As a result, the clothing must be cleaned less frequently. Overall, it has been shown that in addition to the expected benefits but also the carding quality is better.

Gemäß einer bevorzugten Ausführungsform beträgt der Kopfwinkel des Zahns 90°. Hierdurch ergibt sich, dass auch nach Überschleifen der Garnitur gleiche Verhältnisse an allen Zähnen vorliegen, was wiederum zu einer Verbesserung der Kardierqualität führt.According to a preferred embodiment, the head angle of the tooth is 90 °. This results in the same conditions being present on all teeth even after the set has been ground, which in turn leads to an improvement in the carding quality.

Besonders bevorzugt wird zudem, wenn die Länge der Kopffläche mindestens 25% der Zahnteilung entspricht.In addition, it is particularly preferred if the length of the top surface corresponds to at least 25% of the tooth pitch.

Bevorzugt wird ferner, wenn die Länge der Kopffläche mindestens dem Dreifachen, vorzugsweise dem Fünffachen ihrer Breite entspricht. Schließlich hat sich als günstig herausgestellt, wenn die Länge der Kopffläche größer oder gleich der halben Zahnhöhe, gemessen vom Zahngrund bis zur Zahnspitze ist. Hierdurch entsteht eine relativ niedrige Garnitur, die überraschenderweise zu guten Kardierverhältnissen führt. Besonders bevorzugt wird, wenn die Länge der Kopffläche der Zahnhöhe entspricht.It is further preferred if the length of the top surface corresponds to at least three times, preferably five times its width. Finally, it has proven to be advantageous if the length of the head surface is greater than or equal to half the tooth height, measured from the tooth base to the tooth tip. This results in a relatively low set, which surprisingly leads to good Kardierverhältnissen. It is particularly preferred if the length of the top surface corresponds to the tooth height.

Vorteilhaft ist schließlich auch, wenn der sich an die Kopffläche anschließende Zahnrücken mit der nachfolgenden Zahnbrust einen Winkel zwischen 20 und 30°, vorzugsweise 25° einschließt. Dieser Öffnungswinkel zwischen Zahnrücken und Zahnbrust ist tendenziell kleiner als bei den Garnituren des Standes der Technik; er reicht jedoch aus, um für eine problemlose Übernahme der Fasern von der in Arbeitsrichtung vorgelagerten Walze zu sorgen.Finally, it is also advantageous if the tooth back adjacent to the head surface encloses an angle between 20 and 30 °, preferably 25 °, with the following tooth face. This opening angle between tooth back and tooth face tends to be smaller than in the kits of the prior art; however, it is sufficient to ensure trouble-free transfer of the fibers from the upstream roller in the working direction.

Ganz besonders eignet sich die zuvor beschriebene Ganzstahlgarnitur für Trommeln von Baumwollkarden, sog. Hochleistungskarden, mit einer Trommelumfangsgeschwindigkeit von mehr als 1500m/min sowie einer Trommelganzstahlgamitur mit einer Gesamthöhe von weniger als 3mm und einer Fußbreite von weniger als 0,7mm. Für eine solche, mit einer erfindungsgemäßen Ganzstahlgarnitur bestückten Baumwollkarde wird daher gesondert Schutz beansprucht.Very particularly suitable is the previously described all-steel set for drums of cotton cards, so-called. Hochleistungsungskarden, with a drum peripheral speed of more than 1500m / min and a Trommelganzstahlgamitur with a total height of less than 3mm and a foot width of less than 0.7mm. For such, equipped with an inventive all-steel clothing cotton card is therefore claimed separately protection.

Die Umfangsdrehrichtung der Walzen ist in der Fig. 1 jeweils durch Pfeile dargestellt.1 shows a schematic representation of a carding machine with a drum 1, feed rollers 2, a licker-in 3 and turning rollers 4. The circumferential direction of rotation of the rollers is shown in FIG. 1 by arrows.

Die im folgenden beschriebene Garnitur betrifft jeweils solche Walzen bzw. Trommeln, die Fasern von den in Arbeitsrichtung vorgelagerten Walzen aktiv übernehmen. Beispielhaft sind das bei der in Fig. 1 gezeigten Darstellung der Vorreißer 3, die Wenderwalzen 4 und insbesondere die Trommel 1.The clothing described below relates in each case to such rollers or drums which actively take over fibers from the rollers arranged upstream in the working direction. By way of example, in the representation of the licker-in 3 shown in FIG. 1, the turning rollers 4 and in particular the drum 1 are shown.

Fig. 2 zeigt nun abschnittsweise einen Sägezahndraht einer Ganzstahlgarnitur, wie sie für die in Fig. 1 gezeigte Trommel vorgesehen ist. Es handelt sich hierbei um einen Sägezahndraht mit einer Gesamthöhe von 2mm und einer Zahnteilung, gemessen von Zahnspitze 5 bis zur nächsten 5' von 1,7mm. Der zur Vertikalen gemessene Brustwinkel α der Zahnbrust 6 beträgt bei dem hier gezeigten Ausführungsbeispiel 40°. Anders als bei bisher bekannten Ganzstahlgarnituren schließt sich an die Zahnspitze nicht unmittelbar der Zahnrücken 7 an; vielmehr ist zunächst eine Kopffläche 8 vorgesehen. Der Winkel der Kopffläche β, wiederum gemessen zur Vertikalen, beträgt bei dem in Fig. 2 gezeigten Ausführungsbeispiel 87°. Die Länge L der Kopffläche 8 beträgt 0,5mm, ihre Breite B (vgl. Fig. 3) beträgt 0,07 mm. Die Zahnhöhe H, gemessen vom Zahnfuß bis zur Zahnspitze 5 beträgt geringfügig weniger als 0,5mm.Fig. 2 shows a section of a sawtooth wire of an all-steel clothing, as provided for the drum shown in Fig. 1. It is a sawtooth wire with a total height of 2mm and a pitch, measured from tooth tip 5 to the next 5 'of 1.7mm. The measured to the vertical breast angle α of the tooth face 6 is 40 ° in the embodiment shown here. Unlike previously known all-steel sets, the tooth tip does not directly adjoin the tooth back 7; Rather, a top surface 8 is initially provided. The angle of the head surface β, again measured to the vertical, is 87 ° in the embodiment shown in FIG. The length L of the top surface 8 is 0.5 mm, its width B (see Fig. 3) is 0.07 mm. The tooth height H, measured from the tooth root to the tooth tip 5, is slightly less than 0.5 mm.

Der durch die Zahnbrust 6 und den Zahnrücken 7 eingeschlossene Winkel γ beträgt bei dem hier gezeigten Ausführungsbeispiel 24°.The included by the tooth face 6 and the back of the teeth 7 angle γ is 24 ° in the embodiment shown here.

In den Fig. 4 und 5 wird eine weitere Variante eines Sägezahndrahtes für eine erfindungsgemäße Ganzstahlgarnitur gezeigt. Für gleiche und ähnliche Bauteile werden dieselben Bezugszeichen wie für das vorherige Ausführungsbeispiel verwendet.FIGS. 4 and 5 show a further variant of a sawtooth wire for an all-steel clothing according to the invention. For identical and similar components, the same reference numerals are used as for the previous embodiment.

Im Gegensatz zu dem vorherigen Ausführungsbeispiel beträgt der Abstand von Zahnspitze 5 bis zur benachbarten Zahnspitze 5' lediglich 1,5mm. Der Brustwinkel α beträgt lediglich 30°. Der zwischen Zahnbrust 6 und Zahnrücken 7 eingeschlossene Winkel γ beträgt bei diesem Ausführungsbeispiel 25°.In contrast to the previous embodiment, the distance from the tooth tip 5 to the adjacent tooth tip 5 'is only 1.5 mm. The breast angle α is only 30 °. The included between tooth face 6 and 7 tooth back angle γ is 25 ° in this embodiment.

Im folgenden wird die Wirkungs- und Funktionsweise der zuvor beschriebenen Ausführungsbeispiele näher erläutert.In the following the operation and operation of the embodiments described above will be explained in more detail.

Grundsätzlich unterscheiden sich die beiden Ausführungsbeispiele nicht. Der in Fig. 2 dargestellte Sägezahndraht weist jedoch einen größeren Brustwinkel auf, der grundsätzlich für eine aktivere Faserübemahme günstig ist. Bestimmend für beide Varianten ist jedoch, dass bei einer verhältnismäßig geringen Zahnhöhe eine lange Kopffläche vorgesehen ist, die nahezu nicht geneigt ist und die daher der Zahnspitze und der gesamten Garnitur eine erhöhte Stabilität verleiht. Neben diesen Vorteilen ist jedoch besonders herauszuheben, dass sich die Zahngeometrie auch nach Überschleifen der Garnitur praktisch nicht ändert, so dass zum einen an allen Zähnen praktisch gleiche Verhältnisse vorliegen, und zum anderen die Kardierqualität sich auch nach dem Schleifen der Garnituren nicht ändert.Basically, the two embodiments do not differ. However, the sawtooth wire shown in Fig. 2 has a larger breast angle, which is basically favorable for a more active Faserübemahme. However, it is decisive for both variants that, given a relatively low tooth height, a long head surface is provided which is almost not inclined and which therefore gives the tooth tip and the entire clothing increased stability. In addition to these advantages, however, is particularly noteworthy that the tooth geometry practically does not change even after blending the set, so that on the one hand on all teeth practically the same conditions exist, and on the other hand, the carding does not change even after grinding the trimmings.

Das Aufziehen der Garnituren erfolgt in herkömmlicher Weise.The mounting of the sets is done in a conventional manner.
