Description
Die Erfindung betrifft eine Spinnmaschine nach dem Oberbegriff des unabhängigen Anspruchs.The invention relates to a spinning machine according to the preamble of the independent Claim.
Bevorzugt wird eine Verdichtungseinrichtung im Anschluss an ein Streckwerk bei spielsweise in einer Ringspinnmaschine angeordnet, wobei der Siebkörper auf der Ausgangswalze des Streckwerks sitzt. Im Betrieb von Spinnmaschinen nach dem Oberbegriff können sich Probleme durch Schmutzablagerungen zwischen dem Sieb körper und dem Saugeinsatz einstellen, beispielsweise durch Verstopfungen in der Perforation oder durch unzulässigen Verschleiss, wenn durch Schmutzablagerungen die Lage des Saugeinsatzes gegenüber dem Siebkörper verändert wird.A compression device following a drafting system is preferred arranged for example in a ring spinning machine, the screen body on the Output roller of the drafting system sits. In the operation of spinning machines after The generic term can be problems due to dirt deposits between the sieve adjust the body and the suction insert, for example due to blockages in the Perforation or through inadmissible wear and tear if due to dirt deposits the position of the suction insert relative to the screen body is changed.
Dementsprechend ist es Aufgabe der vorliegenden Erfindung, eine Spinnmaschine mit einer Verdichtungseinrichtung so weiterzuentwickeln, dass Schmutzablagerungen von vornherein unterbunden sind.Accordingly, it is an object of the present invention to use a spinning machine to develop a compacting device so that dirt deposits from are prevented in advance.
Diese Aufgabe wird durch eine Spinnmaschine mit den Merkmalen des unabhängigen Anspruchs gelöst. Die abhängigen Ansprüche betreffen vorteilhafte Weiterbildungen.This task is performed by a spinning machine with the characteristics of the independent Claim solved. The dependent claims relate to advantageous developments.
Im folgenden wird die Erfindung anhand der schematischen Figur im einzelnen erläu tert.The invention is explained in detail below with reference to the schematic figure tert.
Ein Siebkörper 20, der auf einer Siebfläche 22 eine Perforation 24 aufweist, ist knapp über einem Saugeinsatz 10 gehalten, in dem sich ein Saugschlitz 12 im Bereich der Perforation 24 befindet. Der Saugschlitz 12 ist durch einen Schlitzrand 13 begrenzt, um welchen herum sich ein Randbereich 14 erstreckt. Bevorzugt ist der Randbereich 14 gegenüber der umliegenden Oberfläche des Saugeinsatzes 10 etwas erhöht, so dass der Randbereich 14 näher an dem Siebkörper 20 angeordnet ist, als die übrigen Berei che des Saugeinsatzes 10. A screen body 20 , which has a perforation 24 on a screen surface 22 , is held just above a suction insert 10 , in which a suction slot 12 is located in the area of the perforation 24 . The suction slot 12 is delimited by a slot edge 13 , around which an edge area 14 extends. Preferably, the edge area 14 is slightly raised relative to the surrounding surface of the suction insert 10 , so that the edge area 14 is arranged closer to the screen body 20 than the other areas of the suction insert 10 .
Bevorzugt ist der Siebkörper 20 eine rotationssymmetrische, in einem schmalen Be reich perforierte Trommel, welche drehfest mit einer Welle 21 verbunden ist. Der Saug einsatz 10 wird im inneren des Siebkörpers 20 durch einen Halter 16 gehalten, wel cher Teil einer Absaugeinrichtung sein kann, die an eine Unterdruckquelle angeschlos sen ist. Der Saugeinsatz 10 ist wenigstens zum Teil kreiszylindrisch ausgebildet, so dass er mit seiner dem Siebkörper 20 zugewandten Oberfläche nahe an der Innenseite des Siebkörpers 20 liegt. Da der Randbereich 14 gegenüber den übrigen Bereichen des Saugeinsatzes erhöht ist, ist der Abstand zwischen dem Siebkörper 20 und dem Saugeinsatz 10 im Randbereich 14 besonders gering. Es ist vorteilhaft, den Saugein satz aus Kunststoff auszuführen, und die Erhöhung im Randbereich 14 so zu wählen, dass der Saugeinsatz 10 nach der Montage im Siebkörper 20 im Randbereich 14 einzu laufen ist. Damit wird erreicht, dass der Spalt zwischen dem Randbereich 14 des Saug einsatzes 10 und dem Siebkörper 20 äusserst gering ist, so dass sich der Saugeinsatz 10 und der Siebkörper 20, welcher über den Saugeinsatz 10 wegbewegt wird, mehr oder weniger ständig berühren können. Bei einer rotationssymmetrischen Anordnung ist es zweckmässig, den Saugeinsatz 10 mittels Wälzlagern im Siebkörper 20 zu la gern, so dass die relative Lage des Saugeinsatzes zum Siebkörper ständig erhalten bleibt. Die Erhöhung im Randbereich 14 bewirkt, dass Partikel eines Fasermaterials 30, welches über die Siebfläche 22 geführt wird, und durch die Durchbrüche oder Löcher der Perforation in das innere des Siebkörpers 20 gelangen, nur in den Saugschlitz 12 des Saugeinsatzes 10, nicht aber zwischen den Siebkörper 20 und den Saugeinsatz 10 gelangen können, wo sich sonst Ansammlungen von Fasermaterial bilden könnten oder die Perforation wenigstens teilweise zugelegt werden könnte.Preferably, the sieve body 20 is a rotationally symmetrical drum richly perforated in a narrow loading, which drum is connected in a rotationally fixed manner to a shaft 21 . The suction insert 10 is held in the interior of the sieve body 20 by a holder 16 , which can be part of a suction device that is ruled out to a vacuum source. The suction insert 10 is circular-cylindrical at least in part, so that it with its side facing the screen body 20 facing surface close to the inner side of the screen body 20 is located. Since the edge area 14 is raised compared to the other areas of the suction insert, the distance between the screen body 20 and the suction insert 10 in the edge area 14 is particularly small. It is advantageous to run the suction insert made of plastic and to select the elevation in the edge region 14 so that the suction insert 10 is to be run in the edge region 14 after installation in the sieve body 20 . This ensures that the gap between the edge region 14 of the suction insert 10 and the sieve body 20 is extremely small, so that the suction insert 10 and the sieve body 20 , which is moved away via the suction insert 10 , can touch more or less constantly. In the case of a rotationally symmetrical arrangement, it is expedient to load the suction insert 10 by means of roller bearings in the sieve body 20 , so that the relative position of the suction insert to the sieve body is constantly maintained. The increase in the edge region 14 has the effect that particles of a fiber material 30 which is guided over the screen surface 22 and pass through the perforations or perforations into the interior of the screen body 20 only into the suction slot 12 of the suction insert 10 , but not between the Sieve body 20 and the suction insert 10 can reach, where otherwise accumulations of fiber material could form or the perforation could at least partially increase.
Es ist zweckmässig, die Perforation 24 nicht wesentlich breiter als den Saugschlitz 12 auszuführen. Gemäss der Figur liegt der Schlitzrand 13 im linken unteren Bereich des Saugschlitzes 12 gerade über den äussersten Durchbrüchen der Perforation 14, eben so im oberen rechten Bereich. Somit liegt der Schlitzrand 13 mindestens teilweise hin ter den äussersten Durchbrüchen im Siebkörper 20. Die Perforation 24, insbesondere aus kreisrunden nebeneinanderliegenden Löchern bestehend, ist in Laufrichtung L des Fasermaterials bandförmig am Siebkörper 20 angeordnet. Sie überragt den Saugschlitz in einer Richtung quer zur Laufrichtung L des Fasermaterials 30 nicht oder nur unwe sentlich. Der Halter 16 ist bevorzugt rohrförmig ausgebildet. Zwischen dem Saugeinsatz 10, soweit er mit dem Siebkörper 20 zusammenarbeitet, und dem Halter 16 befindet sich ein Bereich 11 mit einer Querschnittsschwächung, so dass sich der Saugeinsatz 10 vom Halter lösen kann, falls sich trotz der erwähnten Massnahmen gegen Schmutz ablagerungen dennoch so viel Schmutz ansammeln kann, dass zwischen der bewegten Siebfläche 22 und dem Saugeinsatz 10 eine unzulässig hohe Reibung herrscht. It is expedient not to make the perforation 24 significantly wider than the suction slot 12 . According to the figure, the slot edge 13 lies in the lower left area of the suction slot 12 just above the outermost openings of the perforation 14 , just as in the upper right area. Thus, the slot edge 13 lies at least partially towards the outermost openings in the screen body 20 . The perforation 24 , in particular consisting of circular adjacent holes, is arranged in a band shape on the screen body 20 in the running direction L of the fiber material. It does not protrude beyond the suction slot in a direction transverse to the running direction L of the fiber material 30 or only insignificantly. The holder 16 is preferably tubular. Between the suction insert 10 , insofar as it cooperates with the sieve body 20 , and the holder 16 there is an area 11 with a cross-sectional weakening, so that the suction insert 10 can detach itself from the holder if so much dirt is deposited despite the measures against dirt mentioned can accumulate that there is an impermissibly high friction between the moving screen surface 22 and the suction insert 10 .
