Description
Die Erfindung betrifft eine Vorrichtung an einer Spinnmaschine zum Verstrecken und Verdichten eines Stapelfaserverbandes, mit einem ein Oberriemchen mit Oberriemchenkäfig enthaltenden Streckwerk, mit einer Verdichtungszone, mit einem den Stapelfaserverband durch die Verdichtungszone transportierenden luftdurchlässigen Transportmittel, mit einem der Verdichtungszone zugeordneten, vom Transportmittel abgedeckten, an einem Unterdruckkanal angeordneten Saugschlitz sowie mit einer dem Streckwerk zugeordneten, den Stapelfaserverband quer zur seiner Transportrichtung changierenden Changiereinrichtung, an deren Changierantrieb auch der Unterdruckkanal angeschlossen ist.The The invention relates to a device on a spinning machine for drawing and compacting a staple fiber bandage, with a top apron with upper apron cage containing drafting system, with a compression zone, with a den Staple fiber strand transporting through the compression zone air-permeable Means of transport, associated with one of the compression zone, from the means of transport covered, arranged on a vacuum channel suction slot and with a the drafting associated, the staple fiber strand transverse to the transport direction iridescent traversing device, connected to the traversing drive and the vacuum channel is.
Das Ausgangswalzenpaar eines Streckwerks definiert eine Ausgangsklemmlinie, bis zu welcher der dem ersponnenen Faden erteilte Spinndrall zurückläuft. Dabei entsteht an der Ausgangsklemmlinie ein so genanntes Spinndreieck, dessen Basis breiter ist als der Durchmesser des ersponnenen Fadens und welches üblicherweise Randfasern enthält, die nicht ordnungsgemäß in den entstehenden Faden eingebunden werden und somit wenig oder nichts zur Festigkeit des Fadens beitragen. Zur Erhöhung der Qualität des Fadens ist man daher bestrebt, die Basis des Spinndreiecks möglichst klein zu halten. Aus diesem Grunde sind bei vielen Streckwerken Mittel zum Verdichten des Stapelfaserverbandes vor der Drehungserteilung vorgesehen.The Outgoing roller pair of a drafting system defines an output clamping line, up to which of the spun yarn issued spinning spin runs back. there arises at the output terminal line a so-called spin triangle, whose base is wider than the diameter of the spun thread and which usually Contains edge fibers, the not properly in the resulting thread are involved and thus little or nothing contribute to the strength of the thread. To increase the quality of the thread one is therefore anxious, the base of the spinning triangle as possible to keep small. For this reason are in many drafting means for compacting the staple fiber strand prior to rotation intended.
Die Mittel zum Verdichten enthalten häufig einen Saugschlitz, mit dessen Hilfe der Stapelfaserverband pneumatisch gebündelt werden soll. Da der Stapelfaserverband, wie bekannt, im Streckwerk üblicherweise quer zu seiner Transportrichtung changiert wird, damit die Riemchen und die Walzenbezüge nicht zu zeitig verschleißen, besteht die Gefahr, dass der changierende Stapelfaserverband nicht vom Saugschlitz erfasst wird.The Means for compacting often include a suction slot, with whose help the staple fiber composite are pneumatically bundled should. Since the staple fiber strand, as is known, in the drafting usually is transversely to its transport direction, so that the straps and the roll covers do not wear out too soon, there is a risk that the iridescent staple fiber bandage will not work Suction slot is detected.
Bei
einer bekannten Vorrichtung der eingangs genannten Art gemäß der
Eine
vergleichbare Vorrichtung ist durch die
Durch das deutsche Patent 882 066 ist eine Vorrichtung bekannt geworden, bei welcher das Verdichten eines Stapelfaserverbandes im Hauptverzugsfeld eines Streckwerks durchgeführt wird. Hierfür ist ein Unterriemchen in einem mittleren Teil luftdurchlässig ausgeführt und an einen Saugschlitz angeschlossen. Eine Changiereinrichtung ist für diese Vorrichtung nicht offenbart.By German Patent 882,066 a device has become known, in which the compression of a staple fiber strand in the main drafting field a drafting system carried out becomes. Therefor is a Unterriemchen air permeable in a middle part and executed connected to a suction slot. A traversing device is for this device not revealed.
Der Erfindung liegt die Aufgabe zu Grunde, eine Vorrichtung der eingangs genannten Art so wenig aufwendig wie möglich zu gestalten.Of the Invention is based on the object, a device of the above mentioned type to make as little effort as possible.
Die Aufgabe wird dadurch gelöst, dass das Oberriemchen des Streckwerks das Transportmittel ist und dass der Unterdruckkanal im Oberriemchenkäfig gleitend geführt ist.The Task is solved by that the upper apron of the drafting system is the means of transport and that the vacuum duct is slidably guided in the upper apron cage.
Abweichend vom eingangs genannten Stand der Technik, findet bei der erfindungsgemäßen Vorrichtung das Verdichten des Stapelfaserverbandes im Hauptverzugsfeld des Streckwerks statt, was zum einen zu einer verkürzten Bauweise führt und zum anderen weniger Bauteile benötigt. Das erfindungsgemäß luftdurchlässig ausgeführte Oberriemchen enthält neben seiner üblichen Aufgabe als Führungselement eines Stapelfaserverbandes jetzt eine Zusatzfunktion, die dem Verdichten des Stapelfaserverbandes dient. Auch der dem Oberriemchen zugehörige Oberriemchenkäfig erhält eine Zusatzfunktion, indem er nicht nur dem Führen des Oberriemchens, sondern auch als Halterung und Gleitführung des Saugkanals dient. Wenn, wie bei Doppelriemchenstreckwerken üblich, auch ein Unterriemchentisch mit Unterriemchen vorhanden ist, dann ist der Stapelfaserverband in der Verdichtungszone zwischen dem als Oberriemchen ausgebildeten luftdurchlässigen Transportmittel und dem Unterriemchen geführt. Das Oberriemchen selbst braucht nicht zu changieren, da ja der den Saugschlitz enthaltende Unterdruckkanal synchron zur Changierbewegung des Stapelfaserverbandes geführt ist.deviant from the aforementioned prior art, takes place in the device according to the invention the compaction of the staple fiber strand in the main drafting zone of the Draft instead, which leads to a shortened construction and on the one hand on the other hand, fewer components needed. The invention permeable executed Oberriemchen contains next his usual Task as a guiding element a staple fiber bandage now an additional function that the compacting of the staple fiber bandage. Also the Oberriemchen associated Oberriemchenkäfig receives one Additional function by not only guiding the top apron, but also as a holder and sliding guide the suction channel is used. If, as usual with Doppelriemchenstreckwerken, too a Unterriemchentisch with Unterriemchen is present, then is the staple fiber strand in the compression zone between the as Oberriemchen trained air-permeable means of transport and led the Unterriemchen. The Oberriemchen itself does not need to change, because of the Suction slot containing vacuum channel synchronous to the traversing movement led the staple fiber association is.
Vorteilhaft ist für die Oberriemchen zweier benachbarter Spinnstellen ein gemeinsamer Oberriemchenkäfig und ein gemeinsamer Unterdruckkanal vorgesehen, in Anpassung an die bisher bereits üblichen Druckwalzenzwillinge ohne die erfindungsgemäßen Einrichtungen. Der Unterdruckkanal ist zweckmäßig beidseits der Oberriemchenkäfigs an einer Changierstange des Changierantriebes befestigt.Advantageous is for the top aprons of two adjacent spinning stations a common apron cradle and a common vacuum channel provided, in adaptation to the usual ones already Pressure roller twins without the devices according to the invention. The vacuum channel is appropriate on both sides the top apron cage attached to a traversing rod of the traversing drive.
