Description

Offenend-Spinnvorrichtung Open-end spinning device
Die vorliegende Erfindung betrifft eine Offenend-Spinnvor¬ richtung mit einem auswechselbaren Spinnrotor, einer Speise¬ vorrichtung zum Zuführen eines Faserverbandes, einer Vor¬ richtung zur Auflösung der Fasern in Einzelfasern, einem ein Fadenabzugsrohr und einen Faserspeisekanal enthaltenden Deckel und einem, teilweise in den Rotor ragenden Deckel¬ fortsatz.The present invention relates to an open-end spinning device with an interchangeable spinning rotor, a feed device for feeding a fiber assembly, a device for dissolving the fibers in individual fibers, a cover containing a thread take-off tube and a fiber feed channel and a part partially in the rotor protruding lid continuation.
Damit ein Offenend-Garn von guter Qualität hergestellt werden kann, müssen gewisse Randbedingungen bei der gegen¬ seitigen Anordnung und der Dimensionierung des Rotors, des Speisekanals und des den Rotor schliessenden Deckels er¬ füllt werden.In order that an open-end yarn of good quality can be produced, certain boundary conditions have to be met in the mutual arrangement and dimensioning of the rotor, the feed channel and the cover closing the rotor.
-Mit einer Spinnvorrichtung, die optimal ausgelegt ist, lassen sich nur Fasern verarbeiten, deren mittlere Stapel¬ länge innerhalb eines verhältnismässig kleinen Bereiches liegt.With a spinning device that is optimally designed, only fibers can be processed whose average stack length is within a relatively small range.
Um auch Fasern z.B. mit grösserer Stapellänge zu einem Garn entsprechender Qualität verspinnen zu können,"" ist es er¬ forderlich, einen Rotor mit grösserem Durchmesser in die Spinnvorrichtung einzusetzen. Durch diese Massnahme werden jedoch die Faserspeisung und der Lufthaushalt wegen desIn order to be able to also spin fibers with a greater staple length to a yarn of appropriate quality, "" it is necessary to insert a rotor with a larger diameter into the spinning device. By this measure, however, the fiber feed and the air balance due to the
O PI sich ergebenden grösseren Abstandes zwischen dem Rotorrand und dem in den Rotor ragenden, den Faserspeisekanal und den Fadenabzugskanal aufnehmenden Teil des Rotordeckels der- massen geändert, dass sich kein brauchbares Garn mehr herstellen lässt.O PI The resulting greater distance between the rotor edge and the part of the rotor cover protruding into the rotor and receiving the fiber feed channel and the thread take-off channel is changed so much that a usable yarn can no longer be produced.
Dieser Mangel wird bisher dadurch behoben, dass mit dem Rotor auch der ganze die Faserzufuhr und das Fadenabzugs¬ rohr enthaltende Deckel ausgewechselt wird. Diese Massnahme ist jedoch aufwendig und verursacht hohe Kosten, vor allem bei Spinnvorrichtungen, bei denen der Deckel nicht nur den Faserspeisekanal und das Fadenabzugsrohr enthält, son¬ dern noch weitere Teile wie, z.B. die Faserspeise- und Faserauflösewalze.This deficiency has so far been remedied by replacing the entire cover containing the fiber feed and the thread draw-off tube with the rotor. However, this measure is complex and causes high costs, especially in the case of spinning devices in which the cover not only contains the fiber feed channel and the thread take-off tube, but also other parts such as, e.g. the fiber feed and fiber dissolving roller.
Die Erfindung hat nun die Aufgabe, eine einfache und kostensparende Vorrichtung zu schaffen, die die Verwendung von Rotoren mit voneinander verschieden grossen Durchmessern unter Beibehaltung der spinntechnologisch wichtigen Para- eter für die Garnherstellung zulässt.The object of the invention is now to create a simple and cost-saving device which allows the use of rotors with diameters of different sizes while maintaining the parameters important for spinning technology for yarn production.
Diese Aufgabe wird dadurch gelöst, dass am Deckel ein auswechselbarer Aufsatz zum Anpassen des Deckels an den Spinnrotor vorgesehen ist.This object is achieved in that an interchangeable attachment is provided on the cover for adapting the cover to the spinning rotor.
Anhand eines illustrierten Ausführungsbeispieles wird die Erfindung näher erläutert.The invention is explained in more detail with the aid of an illustrated embodiment.
Die Zeichnung zeigt einen Offenend-Spinnrotor mit einge- ■ setztem Aufsatz.The drawing shows an open-end spinning rotor with an inserted ■ attachment.
Durch einen Faserspeisekanal 1 werden vereinzelte Fasern mittels eines Transportluftstromes auf eine Gleitfläche 2 eines auf einer drehenden Welle 3 fliegend aufgesetzten Spinnrotors 4 (strichpunktiert dargestellt) gespeist. Die Fasern gleiten entlang der Gleitfläche 2 in die Faser¬ sammeirinne 5 im grössten Rotorinnendurchmesser Dl und werden zu einem Faden zusammengedreht und durch das kon- zentrisch zur Rotorwelle 3 liegende Fadenabzugsrohr 6 aus dem Rotor 4 abgezogen.Through a fiber feed channel 1, individual fibers are fed by means of a transport air stream onto a sliding surface 2 of a spinning rotor 4 (shown in phantom) on a rotating shaft 3. The fibers slide along the sliding surface 2 into the fiber collecting channel 5 in the largest rotor inner diameter D1 and are twisted together into a thread and drawn out of the rotor 4 through the thread draw-off tube 6 which is concentric to the rotor shaft 3.
Die beim Austausch des Rotors 4 durch einen Rotor 7 mit grösserem Innendurchmesser D2 sich stark vergrössernde freie Flugbahn der Fasern vom Ende 9 des Faserspeisekanals 1 zur Gleitfläche 8 im Rotor 7 und die damit verbundene starke Erweiterung des Luftaustrittsquerschnitts zwischen dem in dem Rotor ragenden Deckelfortsatz 10 und dem offenen Ende des Rotors, werden durch einen auf den Fortsatz 10 aufsteck- baren, als Erweiter ngsring 11 ausgebildeten Aufsatz, kor¬ rigiert.The free flight path of the fibers, which increases greatly when the rotor 4 is replaced by a rotor 7 with a larger inner diameter D2, from the end 9 of the fiber feed channel 1 to the sliding surface 8 in the rotor 7 and the associated widening of the air outlet cross section between the lid extension 10 and projecting in the rotor The open end of the rotor is corrected by an attachment which can be plugged onto the extension 10 and is designed as an extension ring 11.
Mit dem Ring 11, der satt und übergangsfrei auf dem Deckelfortsatz 10 sitzt und mittels einer Feststellschraube 13 befestigt ist, werden die optimalen Spinnbedingungen wieder hergestellt. Der Ring 11 weist als Verlängerung für den Faserspeisekanal 1 eine Bohrung 12 auf, deren Achse parallel oder im wesentlichen parallel zur Drehebene des Rotors verlaufen kann.With the ring 11, which sits snugly and without transition on the lid extension 10 and is fastened by means of a locking screw 13, the optimal spinning conditions are restored. As an extension of the fiber feed channel 1, the ring 11 has a bore 12, the axis of which can run parallel or substantially parallel to the plane of rotation of the rotor.
Der Durchmesser der Bohrung 12 ist grösser als derjenige des Faserspeisekanals 1 an dessen Ende 9. Die Bohrung 12 kann auch einen andersartigen, z.B. rechteckigen Querschnitt aufweisen. Der Faser/Luftstrom erfährt durch diese Aus- bildung und Anordnung der Bohrung 12 eine geringfügige 'Ablenkung in Richtung auf die Drehebene des Rotors 7, wodurch der Auftreffbereich der Fasern an der Gleitfläche 8 des Rotors 7 demjenigen auf der Gleitfläche 2 des Rotors 4 entspricht. Auch tritt durch die Querschnittsvergrösserung des Faserspeisekanals 1 in der Bohrung 12 eine erwünschte Verteilung der eingespeisten Fasern nahe der Gleitfläche 8The diameter of the bore 12 is larger than that of the fiber feed channel 1 at its end 9. The bore 12 can also have a different cross-section, for example a rectangular cross-section. The fiber / air stream undergoes formation by this initial and arrangement of the hole 12 corresponds to a slight 'deflection in the direction of the plane of rotation of the rotor 7, whereby the impingement of the fibers on the sliding surface 8 of the rotor 7 that on the sliding surface 2 of the rotor. 4 The enlargement of the cross section of the fiber feed channel 1 in the bore 12 also results in a desired distribution of the fed fibers near the sliding surface 8

Die Vorteile des erfindungsgemässen Aufsatzes liegen auf der Hand:The advantages of the attachment according to the invention are obvious:
100 - einfach und kostensparend in der Herstellung,100 - simple and cost-saving to manufacture,
- schnell und problemlos auswechselbar,- quick and easy to replace,
- einfache Lagerhaltung,- easy storage,
- Einhaltung optimaler gewünschter Spinnbedingungen 105 unabhängig vom Rotordurchmesser. - Compliance with optimal desired spinning conditions 105 regardless of the rotor diameter.
