In the region of the path piece (15) where the condensation takes place, a deflection screen (40) is provided at a distance (A) from the outer surface of the suction roll (25).
Description
Die Erfindung betrifft eine Spinnmaschine, insbesondere Ringspinnmaschine nach dem Oberbegriff des Patentanspruchs 1.The The invention relates to a spinning machine, in particular ring spinning machine according to the preamble of claim 1.
Bei
einer bekannten Ringspinnmaschine dieser Art (
Durch die aerodynamische Verdichtung der Fasern, die dem Hochverzug folgt, wird ein Kompaktfaserstrang von rund 1 mm Breite oder weniger erzielt, welcher gleichzeitig die Basis des sich an den Drehungssperrspalt anschließenden Spinndreiecks bildet. Damit reduziert sich konsequenterweise auch die Höhe des Spinndreiecks. Somit kann durch die Tatsache der aerodynamischen Bündelung der Fasern Einfluss auf die Eindrehung des Faserverbandes genommen werden.By the aerodynamic compaction of the fibers following the high distortion a compact fiber strand of about 1 mm width or less is achieved, Which at the same time the basis of the turn-lock gap subsequent Forming a spinning triangle. Consequently, this also reduces the Height of Spinning triangle. Thus, by the fact of the aerodynamic bundling the fibers influence the twisting of the fiber structure become.
Üblicherweise werden bei Ringspinnmaschinen Drei-Zylinder-Streckwerke verwendet, wobei das am Beginn des Hochverzugsfelds vorgesehene mittlere Zylinderpaar im allgemeinen mit Doppelriemchen ausgerüstet ist, die bis nahe an den Eintrittsspalt des Ausgangswalzenpaars reichen.Usually Three-cylinder drafting systems are used in ring spinning machines, wherein the provided at the beginning of the high draft field middle cylinder pair is generally equipped with Doppelriemchen, close to the Entrance gap of the output roller pair range.
Die
Verzüge
von mit einer Flyerlunte gespeisten Drei-Zylinder-Streckwerken liegen
je nach Garnfeinheit bei 25- bis 50-fach, wobei die höheren Verzüge feineren
Garnnummern entsprechen. Man hat auch schon zwischen den Enden der
Riemchen im Hauptverzugsfeld und dem Klemmspalt zwischen den Ausgangszylindern
des Streckwerks mechanische Kondensoren zur Bündelung des Faserverbandes
verwendet (
Der bei den bekannten Ringspinnverfahren und -maschinen erforderliche Blasluftstrom erhöht den für die Bündelung des Faserverbandes in der Saugzone erforderlichen apparativen Aufwand und erschwert die für den Erfolg der Kondensation wesentliche Abstimmung zwischen der Stärke und Richtung des Saugluftstromes einerseits und des Blasluftstromes andererseits.Of the required in the known ring spinning processes and machines Blast air flow increases the for the bundling the fiber structure in the suction zone required equipment and makes it difficult for the success of the condensation essential vote between the Strength and direction of the suction air flow on the one hand and the blast air flow on the other hand.
Das Ziel der vorliegenden Erfindung besteht darin, eine Spinnmaschine, insbesondere Ringspinnmaschine, zu schaffen, mit der eine gute Bündelung des Faserverbandes im Bereich der Saugzone ohne Nutzung von Blasluft erzielt werden kann, wobei eine aufwändige Einjustierung des Saugluftstroms für jede einzelne Spinnstelle vermieden werden soll.The The aim of the present invention is to provide a spinning machine, In particular ring spinning machine, to create, with a good bundling of the Fiber structure in the area of the suction zone without the use of blowing air can be achieved, with a complex Einjustierung the suction air flow for every single spinning station should be avoided.
Zur Lösung dieser Aufgabe ist eine Spinnmaschine mit den Merkmalen des unabhängigen Anspruchs 1 vorgesehen. Vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen angegeben.to solution This object is a spinning machine with the features of the independent claim 1 provided. Advantageous developments of the invention are in the dependent claims specified.
Der so erhaltene Faserverband wird nach dem Austritt aus dem letzten Klemmspalt des Streckwerkes vorzugsweise auf dem Umfang einer Saugwalze befördert. Der Drehungs-Sperrspalt wird zweckmäßigerweise von der Saugwalze und der Drehungssperr-Gegenwalze gebildet. Die Saugzone ist bevorzugt in Umfangsrichtung radial innerhalb des Außenumfangs der Saugwalze ausgebildet und weist zweckmäßig eine etwas größere Breite als der Faserverband auf. Die Luft strömt dabei bevorzugt von außen nach innen in die Saugwalze.Of the so obtained fiber strand becomes after leaving the last one Clamping gap of the drafting device preferably on the circumference of a suction roll promoted. The turn-lock gap is expediently formed by the suction roll and the rotation lock counter roll. The suction zone is preferably in the circumferential direction radially within the outer periphery formed the suction roller and expediently has a slightly larger width as the fiber strand on. The air flows preferably from outside to inside the suction roll.
Die Saugluft wird zweckmäßigerweise von außen insbesondere mit einer im wesentlichen axialen Komponente an den Umfang der Saugwalze im Bereich des Wegstückes herangeführt.The Suction air is expediently from the outside in particular with a substantially axial component to the Scope of the suction roller in the area of the path piece brought.
Der Erfindungsgedanke ist darin zu sehen, dass ohne Blasluft der Saugluftstrom so geführt wird, dass der aus dem Mehrfach-Streckwerk austretende Faserverband in axialer Richtung stark gebündelt wird, und zwar vorzugsweise so, dass seine Breite geringer als 1,5 und vorzugsweise weniger als 1 mm beträgt.The idea of the invention is to be seen in that without blowing air, the suction air flow is guided so that the emerging from the multiple drafting fiber structure is strongly bundled in the axial direction, preferably so that its width is less than 1.5 and preferably less than 1 mm is.
Die erfindungsgemäß vorgesehenen Luftleitmittel veranlassen den angesaugten Saugluftstrom, vor dem Erreichen des Faserverbandes in eine zumindest eine wesentliche Axialkomponente aufweisende Richtung abzubiegen, wobei vorzugsweise zwei gegeneinander gerichtete Teilluftströme von entgegengesetzten Seiten des Faserverbandes auf diesen einwirken, um ihn zu einem schmalen Kompaktfaserstrang zu bündeln. Unmittelbar nach der Einwirkung der einander entgegengerichteten Teilluftströme werden diese dann durch den gelochten Umfangsbereich der Saugwalze ins Innere derselben und von dort zur Absaugung geführt. Gegebenenfalls genügt auch ein im wesentlichen axial zugeführter Unterstrom, wenn an der anderen Seite der Saugzone gemäß Anspruch 6 und 7 eine Wand vorgesehen ist.The provided according to the invention Air-conducting cause the sucked suction air flow, before the Reaching the fiber structure in at least one essential Bend axial component having direction, preferably two directed against each other partial air flows from opposite sides of the fiber structure act on this to make it a narrow Compact fiber strand to bundle. Immediately after the action of the opposing partial air flows this then through the perforated peripheral region of the suction roll into Inside the same and from there to the extraction. If necessary, it is sufficient a substantially axially supplied Undercurrent, if on the other side of the suction zone according to claim 6 and 7, a wall is provided.
