Description

Die vorliegende Erfindung betrifft ein Verfahren zum Aufziehen von Sägezahndrähten auf einer mit einer Garnitur auszurüstenden Walze für Textilmaschinen.The present invention relates to a method for pulling sawtooth wires on a roller to be equipped with a clothing for textile machines.

Mit einer Sägezahngarnitur ausgerüstete Walzen werden in den verschiedensten Textilmaschinen verwendet, z.B. in Krempelmaschinen, in Auflösevorrichtungen, Schlagvorrichtungen, Reissvorrichtungen, Reinigungsvorrichtungen, usw. Das durch diese Sägezahnwalzen bearbeitete Fasergut sollte möglichst regelmässig verteilt werden. Dieses bedingt eine zufällige Spitzenverteilung der Garnituren. Diese wird jedoch durch die bekannten Verfahren zum Aufbringen der Sägezahndrähte auf die Walzen darum nicht erreicht, weil die Spitzenverteilung mindestens teilweise eine regelmässige ist, so dass sich zwischen den Spitzen Gassen bilden, innerhalb derer das Fasergut kaum oder zumindest unvollständig den Spitzen ausgesetzt wird. Es wurde diesem Umstande schon entgegengewirkt, indem mehrere Sägezahndrähte nebeneinanderliegend auf eine jeweilige Walze aufgezogen wurden, wie z.B. in der DE-A-2140701 und US-A-2816325. Diese Verfahren führten jedoch auch nicht zum gesuchten Erfolg.Rollers equipped with a saw tooth set are used in a wide variety of textile machines, e.g. in carding machines, in opening devices, impact devices, tearing devices, cleaning devices, etc. The fiber material processed by these sawtooth rollers should be distributed as regularly as possible. This results in a random tip distribution of the sets. However, this is not achieved by the known methods for applying the sawtooth wires to the rollers because the tip distribution is at least partially regular, so that lanes form between the tips, within which the fiber material is hardly or at least incompletely exposed to the tips. This fact has already been counteracted by pulling several sawtooth wires side by side onto a respective roller, e.g. in DE-A-2140701 and US-A-2816325. However, these methods did not lead to the desired success.

Hier will die Erfindung Abhilfe schaffen. Die Erfindung, wie sie in den Ansprüchen gekennzeichnet ist, löst die Aufgabe, ein Verfahren zum Auf ziehen von Sägezahndrähten auf einer Walze zu schaffen, bei dem auf der Walze von beiden Enden beabstandet ein temporäres Führungsglied angeordnet wird, welches zum Führen mindestens des ersten Ganges der in einer axialen Richtung der Walze verlaufenden Umwicklung dient, wobei jeder nachfolgende Gang durch den jeweils vorangehenden Gang geführt wird, und danach das Führungsglied entfernt wird und die in der entgegengesetzten Richtung verlaufende Umwicklung erfolgt, deren erster Gang durch den ersten Gang der ursprünglichen Umwicklung geführt wird.The invention seeks to remedy this. The invention, as characterized in the claims, achieves the object to provide a method for pulling on sawtooth wires on a roller, in which a temporary guide member is arranged on the roller at both ends, which is used to guide at least the first gear serves the winding running in an axial direction of the roller, each subsequent course being passed through the respective preceding gear, and then the guide member being removed and the winding running in the opposite direction taking place, the first course of which is guided by the first gear of the original winding becomes.

Die durch die Erfindung erreichten Vorteile sind im wesentlichen darin zu sehen, dass eine zufällige Verteilung der Spitzen der Garnitur erreicht wird, so dass das bearbeitete Fasergut vollständig den Spitzen für eine gleichmässige und bei allen Bereichen erfolgende Bearbeitung ausgesetzt wird.The advantages achieved by the invention can essentially be seen in the fact that a random distribution of the tips of the clothing is achieved, so that the processed fiber material is completely exposed to the tips for uniform processing in all areas.

Im folgenden wird die Erfindung anhand von Ausführungswegen darstellenden Zeichnungen näher erläutert.In the following, the invention is explained in more detail with reference to drawings which illustrate the ways of implementation.

Abbildung 1 zeigt schematisch eine mit einer Garnitur auszurüstenden Walze und eine darin eingestochene Rille,
   Abbildung 2 zeigt schematisch den Beginn des Aufbringens einer ersten Sägezahndrahtabschnittes,
   Abbildung 3 zeigt schematisch das Aufbringen des zweiten Sägezahndrahtabschnittes,
   Abbildungen 4 und 5 zeigen verschiedene Ausführungsformen von Sägezahndrähten.Figure 1 shows schematically a roller to be equipped with a set and a groove pierced therein,
Figure 2 shows schematically the beginning of the application of a first sawtooth wire section,
Figure 3 shows schematically the application of the second sawtooth wire section,
Figures 4 and 5 show different embodiments of sawtooth wires.

Die Figur 1 zeigt eine glattwandige Walze 1, die mit einer Garnitur auszurüsten ist. Die axiale Länge der Walze 1 hängt vom jeweiligen späteren Einsatz ab. Der Walzenkörper kann massiv oder ein Hohlzylinder, also Rohrstück sein. Beidseitig sind Wellenstummel 8, 9 für die jeweiligen Lager angedeutet. In den Mantel der Walze wird jetzt bei einer von beiden Enden der Walze denselben Abstand aufweisenden Bereich eine Rille 7 eingestochen. Diese Rille 7 verläuft sinusfömrig und ist in sich geschlossen. In dem gezeichneten Ausführungsbeispiel ist nur eine Rille 7 angedeutet. Offensichtlich können auch mehrere Rillen in einem jeweiligen Abstand angeordnet sein oder dann kann eine einzige Rille 7 vorhanden sein, die jedoch nicht jeweils denselben Abstand von beiden Enden der Walze 1 aufweist.Figure 1 shows a smooth-walled roller 1, which is to be equipped with a set. The axial length of the roller 1 depends on the respective later use. The roller body can be solid or a hollow cylinder, ie a piece of pipe. Shaft ends 8, 9 for the respective bearings are indicated on both sides. A groove 7 is now inserted into the jacket of the roller at an area which has the same distance from both ends of the roller. This groove 7 is sinusoidal and is self-contained. In the illustrated embodiment, only one groove 7 is indicated. Obviously, a plurality of grooves can also be arranged at a respective distance, or a single groove 7 can then be present, which, however, does not have the same distance from both ends of the roller 1.

In diese Rille 7, siehe Figur 2, wird nun vorerst ein Flachdraht 2 eingesetzt und stellenweise, z.B. durch Punktschweissung oder durch ein Löten in der Rille 7 arretiert.A flat wire 2 is now inserted into this groove 7, see FIG. 2, and in places, e.g. locked by spot welding or by soldering in the groove 7.

Danach wird ein erster Sägezahndrahtabschnitt 3 gegen eine Seite des Flachdrahtes 2 gelegt, mit demselben mindestens stellenweise verbunden und darauf um die Walze 1 gewickelt. Dieses Wickeln erfolgt nun auf dem rechtsliegenden Abschnitt der Walze 1, wobei die Wickelrichtung mit dem Pfeil 4 bezeichnet ist. Der erste Gang der Umwicklung ist durch den Flachdraht 2 geführt und die nachfolgenden, sich nach rechts in Richtung des Pfeiles 4 fortsetzenden Gänge durch den jeweiligen vorherigen Gang, wobei in bekannter Weise bis zum Randdraht (nicht gezeichnet) gewickelt wird. Damit ist die rechtsliegende Hälfte der Walze 1 vollständig umwickelt. Durch den sinusförmigen Verlauf des Flachdrahtes 2 ist nun sichergestellt, dass eine zufällige Verteilung der Drahtspitzen vorhanden ist, welche eine optimale Spitzenverteilung zur Folge hat.After that, a first sawtooth wire section 3 placed against one side of the flat wire 2, connected to it at least in places and wound around the roller 1 thereon. This winding is now carried out on the right-hand section of the roller 1, the winding direction being indicated by the arrow 4. The first course of the winding is led through the flat wire 2 and the subsequent courses continuing to the right in the direction of arrow 4 through the respective previous course, winding in a known manner up to the edge wire (not shown). So that the right half of the roller 1 is completely wrapped. The sinusoidal shape of the flat wire 2 now ensures that there is a random distribution of the wire tips, which results in an optimal tip distribution.

Nach erfolgter Bewicklung wird nun der Flachdraht 2 neben dem ersten Sägezahndraht 3 entfernt, da er sonst eine Leerstelle entlang des Umfanges der Walze 1 bilden könnte. Dazu wird er beispielsweise, wie in der Figur 3 gezeigt ist, bis auf den Umfang der Walze 1 abgeschliffen. Das Entfernen kann offensichtlich auch auf andere Weise erfolgen.After winding, the flat wire 2 is now removed next to the first saw tooth wire 3, since otherwise it could form an empty space along the circumference of the roller 1. For this purpose, for example, as shown in FIG. 3, it is ground down to the circumference of the roller 1. The removal can obviously also be done in other ways.

Nun wird mit dem Wickeln des zweiten Sägezahndrahtabschnittes 5 begonnen. Sein erster Umgang ist durch den ersten Umgang des ersten Sägezahndrahtabschnittes 3 geführt, so dass auch hier wieder der sinusförmige Verlauf vorhanden ist. Das Wickeln des zweiten Sägezahndrahtabschnittes 5 erfolgt in Richtung des Pfeiles 6 (siehe Figur 3), wobei wieder jeder Gang durch den jeweils vorangehenden geführt ist und das Wickeln bis zum linksliegenden Randdraht erfolgt. Damit ist nun die gesamte Walze 1 mit der Garnitur ausgerüstet.Now the winding of the second sawtooth wire section 5 is started. His first handling is guided by the first handling of the first sawtooth wire section 3, so that the sinusoidal shape is again present here. The winding of the second sawtooth wire section 5 takes place in the direction of the arrow 6 (see FIG. 3), again each passage being led through the preceding one and the winding is carried out up to the left edge wire. The entire roller 1 is now equipped with the clothing.

Es können verschiedene Ausbildungen von Sägezahndrähten, bzw. deren Füsse verwendet werden, beispielsweise können diese wie in der Figur 3 gezeigt ist, verkettete oder wie in der Figur 4 gezeigt ist, verriegelte Sägezahndrahtabschnitte verwendet werden.Different designs of sawtooth wires, or their feet, can be used, for example, these sawtooth wire sections can be used as shown in FIG. 3, linked or, as shown in FIG. 4, locked.

Gemäss der oben beschriebenen beispielsweisen Ausführung liegt jeweils lediglich ein einziger erster Sägezahndrahtabschnitt 3 und ein jeweils einziger Sägezahndrahtabschnitt 5 vor. Es ist jedoch bei anderen Ausführungen auch vorgesehen, mehrerer erste Sägezahndrahtabschnitte 3 und mehrere zweite Sägezahndrahtabschnitte 5 parallel nebeneinander auf den jeweiligen Walzenabschnitt auf zuwickeln. Entsprechend würde dann nur ein jeweiliger Abschnitt eines jeweiligen ersten Sägezahndrahtabschnittes mit einem Abschnitt des Flachdrahtes 2 verbunden werden, wobei aufeinanderfolgende Gänge der einzelnen Sägezahndrahtabschnitte an dem ihm nächstliegenden der mehreren parallelen ersten Sägezahndrahtabschnitte anliegen würde. Entsprechend würden dann auch die mehreren zweiten Sägezahndrahtabschnitte mit nur einem Abschnitt eines ersten Sägezahndrahtes 3 verbunden und von denselben geführt werden, die vorgängig das nun entfernte Führungsglied 2 berührten. Die weitere gegenseitige Führung der weiteren Gänge der mehreren zweiten Sägezahndrahtabschnitte 5 würde dann entsprechend dem oben beschriebenen Vorgang beim Umwickeln mit dem ersten Sägezahndrahtabschnitt 3 erfolgen. Damit wäre also die Walze 1 beim Bereich des Pfeiles 4 mit mehreren ersten Sägezahndrahtabschnitten 3 und die mit dem Pfeil 6 angedeutete Seite mit mehreren zweiten Sägezahndrahtabschnitten 5 umwickelt, wobei die jeweiligen Gänge parallel zueinander verlaufen.According to the examples described above There is only a single first sawtooth wire section 3 and a single sawtooth wire section 5. In other embodiments, however, it is also provided that a plurality of first sawtooth wire sections 3 and a plurality of second sawtooth wire sections 5 are wound parallel to one another onto the respective roller section. Accordingly, only a respective section of a respective first sawtooth wire section would then be connected to a section of the flat wire 2, with successive courses of the individual sawtooth wire sections resting against the one of the plurality of parallel first sawtooth wire sections closest to it. Correspondingly, the plurality of second sawtooth wire sections would then also be connected to and guided by only a section of a first sawtooth wire 3, which previously previously touched the guide member 2 which has now been removed. The further mutual guidance of the further gears of the plurality of second sawtooth wire sections 5 would then take place in accordance with the process described above when wrapping with the first sawtooth wire section 3. Thus, the roller 1 would be wrapped in the region of the arrow 4 with a plurality of first sawtooth wire sections 3 and the side indicated by the arrow 6 with a plurality of second sawtooth wire sections 5, the respective gears running parallel to one another.
