Abstract
Description
Die Erfindung betrifft eine Spinnmaschine nach dem Oberbegriff des unabhängigen Anspruchs. Sie unterscheidet sich von herkömmlichen Ringspinnmaschinen durch ein Streckwerk, welches mit einer Verdichtungseinrichtung im wesentlichen in Form einer Saugtrommel kombiniert ist. Eine Saugtrommel für eine Spinnmaschine mit Verdichtungseinrichtung ist beispielsweise in der Deutschen Patentanmeldung 19 917 181.5 beschrieben, wobei es in der erwähnten Anmeldung um eine Saugtrommel mit einer profilierten Oberfläche geht.The invention relates to a spinning machine according to the preamble of the independent Claim. It differs from conventional ring spinning machines by Drafting system, which with a compression device essentially in the form of a Suction drum is combined. A suction drum for a spinning machine with Compression device is for example in the German patent application 19 917 181.5 described, wherein in the mentioned application is a Suction drum with a profiled surface goes.
Ringspinnmaschinen mit Verdichtungseinrichtungen werden für ein breites Einsatzgebiet weiterentwickelt. Dementsprechend müssen die Komponenten je nach Einsatzgebiet optimiert werden, damit der Verstreckungs- und Verdichtungsprozess möglichst gleichmässig abläuft. Erfindungsgemäss ist zwischen einem Streckwerk einer Spinnmaschine und einer Verdichtungseinrichtung eine Auslauf-Oberwalze gegen ein Verdichtungselement gedrückt. Während das Vorgarn im Streckwerk zwischen einem ersten Walzenpaar, einem zweiten Walzenpaar und dem dritten Walzenpaar, nämlich der Auslauf-Obermralze und dem Verdichtungselement, verzogen wird, werden die verzogenen Fasern im Bereich längs des Verdichtungselements zwischen den gegen das Verdichtungselement gedrückten Elementen Auslauf-Obermralze und Klemmwalze verdichtet. Die Auslauf-Oberwalze ist mit einer Shore-Härte von weniger als 60° sehr weich, wodurch eine gute Führung der Fasern zwischen der Auslauf-Oberwalze und dem Verdichtungselement, die bevorzugt als perforierte Saugtrommel ausgeführt, besteht.Ring spinning machines with compaction devices are used for a wide range Application area further developed. Accordingly, the components must be different Field of application can be optimized so that the stretching and compression process runs as evenly as possible. According to the invention, there is one between a drafting system Spinning machine and a compacting device against a top roller Compression element pressed. While the roving in the drafting system between one first pair of rollers, a second pair of rollers and the third pair of rollers, namely the upper malt outlet and the compression element, is warped warped fibers in the area along the compression element between the counter the compacting element pressed elements outlet top roller and pinch roller condensed. The outlet top roller is very hard with a Shore hardness of less than 60 ° soft, which ensures good guidance of the fibers between the outlet top roller and the compression element, which is preferably designed as a perforated suction drum, consists.
Eine solche Struktur hat auf das Verziehen und anschliessende Verdichten der Fasern sehr positive Auswirkungen. Mit einer profilierten Oberfläche am Verdichtungselement, insbesondere einer Kannelur, kann die Kontrolle der verzogenen und zu verdichtenden Fasern noch verbessert werden.Such a structure is based on the warping and subsequent compression of the fibers very positive effects. With a profiled surface on the compression element, especially a cannelur, can control the warped and compacted Fibers still need improvement.
Die Erfindung wird im folgenden anhand der Zeichnung im einzelnen beschrieben.The invention is described below with reference to the drawing.
Das Streckwerk umfasst bevorzugt einen ersten Zylinder 23 mit einer ersten Gegenwalze 13, zwischen welchen ein Vorgarn 22 in die Vorverzugszone des Streckwerks einläuft. Anschliessend passiert das Vorgarn 22 die Hauptverzugszone, in welcher das Vorgarn 22 zwischen einem Oberriemchen 15 und einem Unterriemchen 33 auf einer zweiten Gegenwalze 14 bzw. einem zweiten Zylinder 34 geführt wird. Der Verstreckungsvorgang ist beendet, wenn das Vorgarn zwischen einer Auslauf Oberwalze 16 und einem Verdichtungselement 35 durchläuft. Dieses Verdichtungselement ist bevorzugt als Saugtrommel mit einer Perforation ausgebildet. Die Verdichtungszone für das verzogene Vorgarn 22 liegt zwischen den Klemmspalten einerseits der Auslauf-Oberwalze 16 mit dem Verdichtungselement 35 und einer Klemmwalze 36 mit dem Verdichtungselement 35. Anschliessend wird das Garn, welches nach dem Verlassen des Klemmspaltes zwischen der Klemmwalze 36 und dem Verdichtungselement 35 eine Drehung erfährt, auf einen Garnträger aufgewickelt.The drafting system preferably comprises a first cylinder 23 with a first counter roller 13 , between which a roving 22 runs into the draft zone of the drafting system. The roving 22 then passes the main draft zone, in which the roving 22 is guided between an upper apron 15 and a lower apron 33 on a second counter roller 14 or a second cylinder 34 . The drawing process is ended when the roving passes between an outlet top roller 16 and a compression element 35 . This compression element is preferably designed as a suction drum with a perforation. The compression zone for the warped roving 22 lies between the clamping nips on the one hand of the outlet top roller 16 with the compression element 35 and a clamping roller 36 with the compression element 35 . The yarn, which undergoes a rotation after leaving the nip between the nip roller 36 and the compression element 35 , is then wound onto a yarn carrier.
Erfindungsgemäss ist eine der gegen das Verdichtungselement gedrückten Walzen, insbesondere die Auslauf-Oberwalze 16, mit einer Schicht belegt, welche wenigstens im Inneren eine Härte von deutlich weniger als 60° Shore besitzt. Die Oberfläche der Auslauf-Oberwalze 16 hat einen abriebfesten Bezug. Die Auslauf-Oberwalze 16 kann auch einen Zwei-Komponenten-Bezug aufweisen, welcher im Inneren sehr weich, d. h. weniger als 60° Shore ist und Aussen eine abriebfeste Laufschicht besitzt. Um die Fasern im Klemmspalt zwischen der Auslauf-Oberwalze 16 und dem Verdichtungselement 35 sicher zu führen, muss das Verdichtungselement eine definierte Rauhigkeit aufweisen, beispielsweise wie in der eingangs erwähnten DE 19 917 181.5 beschrieben.According to the invention, one of the rollers pressed against the compacting element, in particular the upper discharge roller 16 , is coated with a layer which, at least in the interior, has a hardness of significantly less than 60 ° Shore. The surface of the upper discharge roller 16 has an abrasion-resistant cover. The outlet top roller 16 can also have a two-component cover, which is very soft on the inside, ie less than 60 ° shore, and has an abrasion-resistant running layer on the outside. In order to reliably guide the fibers in the nip between the outlet top roller 16 and the compression element 35 , the compression element must have a defined roughness, for example as described in DE 19 917 181.5 mentioned at the beginning.
