Description

Die Erfindung bezieht sich auf eine Spinnmaschine zum Herstellen von Coregarn, mit einem mindestens eine Faserlunte verziehenden Streckwerk, an welches eine die Faserlunte verdichtende, umlaufende, mit mindestens einer Perforationsspur versehene, unter Saugzug stehende Verdichtungseinrichtung anschließt und mit einer Einrichtung zum Zufuhren von Filament zu der Faserlunte vor der Verdichtungseinrichtung.The invention relates to a spinning machine for producing coregarn, with an at least one roving pulling drafting system, to which a the roving compacting, circumferential, provided with at least one perforation, under Saugzug standing compression device connects and with a device for Feeds of filament to the roving in front of the compactor.

Zum Stand der Technik zählt es, das sogenannte Verdichtungsspinnen mit dem Herstellen von Coregarn zu kombinieren. Hierbei wird einer in einem Streckwerk verfeinerten Faserlunte, bevor sie durch Erteilen von Drehung verfestigt wird, ein Filament zugeführt, das in die Fasern des Faserverbandes als Mantelfasern eingebettet wird. Die Faserlunte wird nach dem Zuführen des Filaments und vor dem Erteilen der Drehung in einer Verdichtungsvorrichtung einem Verdichten unterworfen (DE 19 815 054 C1).It belongs to the state of the art, the so-called compaction spinning with the manufacture to combine from Coregarn. This one is refined in a drafting A roving, before it is solidified by giving rotation, a filament fed, which is embedded in the fibers of the fiber structure as sheath fibers. The Filled roving is done after feeding the filament and before giving the rotation in a compacting device subjected to compression (DE 19 815 054 C1).

Es hat sich in der Praxis herausgestellt, dass der wenn auch geringe, für das Verdichten jedoch erforderliche Anspannungsverzug zwischen dem Ausgangswalzenpaar und dem Klemmwalzenpaar der Verdichtungseinrichtung sich nachteilig auf die Qualität des erzeugten Coregarns auswirkt.It has turned out in practice that, albeit small, for compacting However, required tension distortion between the pair of output rollers and the Pinch roller pair of the compression device adversely affect the quality of produced coregarns.

Es ist daher vorteilhafter, das Coregarn-Filament direkt der Verdichtungszone zuzuführen. Hierbei hat sich jedoch in der Praxis ergeben, dass das Einführen des Coregarn-Filaments von der Seite her in den engen Spalt zwischen z.B. einem Verdichtungsriemchen der Verdichtungseinrichtung und der Ausgangsoberwalze sehr schwierig ist. Aus spinntechnischen Gründen ist nämlich der Abstand zwischen dem Verdichtungselement und dem Ausgangswalzenpaar so eng wie möglich zu gestalten. It is therefore more advantageous to supply the coregarn filament directly to the compression zone. Here, however, it has been found in practice that the introduction of the core yarn filament from the side into the narrow gap between e.g. a compacting belt the compacting device and the output top roller is very difficult. Out For spin-technical reasons, namely the distance between the compression element and make the pair of outfeed rollers as tight as possible.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Möglichkeit für ein leichteres Einführen des Coregarn-Filaments auf der Einlaufseite einer Verdichtungseinrichtung zu schaffen.The invention is therefore based on the object, a possibility for a lighter Introducing the coregarn filament on the inlet side of a compacting device to accomplish.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass der Verdichtungszone für den Faserverband eine Ansaugzone für das Filament in Laufrichtung des Verdichtungselements vorgeordnet ist. Hierdurch ergibt sich als Vorteil ein leichteres Einführen des Filaments. Das Filament kann beispielsweise mittels einer nach vorn verlängerten Verdichtungszone angesaugt werden, wobei der Ansaugbereich die Verdichtungszone für den Faserverband und die ihr vorgeordnete Ansaugzone für das Filament umfasst.This object is achieved in that the compression zone for the fiber structure a suction zone for the filament in the direction of the compression element is upstream. This results in an advantage easier insertion of the Filament. The filament can, for example, by means of a forward extended compression zone be sucked, wherein the suction area the compression zone for comprises the fiber structure and its upstream suction zone for the filament.

In weiterer Ausgestaltung der Erfindung besteht die Möglichkeit einer strömungsmäßigen Trennung von Verdichtungszone und Ansaugzone, wodurch die Möglichkeit eines getrennten Abstellens der Saugwirkung in der Ansaugzone für das Filament geschaffen wird.In a further embodiment of the invention, there is the possibility of a flow Separation of compression zone and suction zone, thereby reducing the possibility of a shut off the suction in the intake zone for the filament created separately becomes.

Erfindungsgemäß kann hierbei die Verdichtungseinrichtung im Zuführbereich für das Filament mindestens eine weitere, unter der Perforationsspur angeordnete Saugöffnung aufweisen.According to the invention, the compression device in the feed region for the Filament at least one further, arranged under the perforation suction opening exhibit.

Bei einer Verdichtungseinrichtung, bei welcher ein Saugschuh und ein diesen umschlingendes Saugriemchen vorgesehen ist, kann der Saugschuh auf seiner der Verdichtungszone abgekehrten Seite die unter der Perforationsspur des Saugriemchens liegende Saugöffnung aufweisen.In a compression device, in which a suction shoe and this umschlingendes Suction cup is provided, the suction shoe on its the compression zone side turned away from under the perforation track of the Saermiemiemchens have lying suction opening.

Bei einer Verdichtungseinrichtung, welche als Siebtrommel ausgebildet ist, kann die Siebtrommel vor der Verdichtungszone die Saugöffnung besitzen.In a compression device which is designed as a sieve drum, the Sieve drum before the compression zone have the suction opening.

Zum Beheben eines Fadenbruchs kann das Ende eines zuzuführenden Coregarn-Filaments im Bereich dieser Ansaugöffnung auf das perforierte Riemchen bzw auf die Siebtrommel aufgelegt werden. Es wird dort angesaugt und durch das umlaufende Riemchen oder die Siebtrommel in die Saugzone mitgenommen oder zumindest dem vom Ausgangswalzenpaar zur Verdichtungseinrichtung laufenden Faserverband zugeführt und von diesem in die Verdichtungszone mitgenommen.To fix a thread breakage, the end of a supplied Coregarn filament in the area of this suction opening on the perforated belt or on the Sieve drum are placed. It is sucked in there and by the circulating Riemchen or the screen drum entrained in the suction zone or at least the fed from the pair of output rollers to the compacting device current fiber association and taken from this in the compression zone.

Neben dem Erleichtern des Zuführens eines Coregarn-Filaments ergeben sich durch die Erfindung weitere Vorteile, nämlich

  • das Coregarn-Filament braucht in manchen Fällen nicht genau auf die Perforation geführt zu werden, auch bei seitlichem Zuführen kann es hierbei mittig auf die Perforationsspur gesaugt werden,
  • das auf die Perforation gesaugte Coregarn-Filament wird mittig dem ebenfalls auf die Perforationsspur gesaugten Faserverband zugeführt.
In addition to facilitating the feeding of a core yarn filament, the invention provides further advantages, namely
  • in some cases, the coregarn filament does not need to be guided exactly to the perforation, even if it is fed laterally, it can be sucked centrally onto the perforation track.
  • The coregarn filament sucked onto the perforation is fed in the middle to the fiber dressing, which is also sucked onto the perforation track.

Wenn die zusätzliche Öffnung auf der Oberseite des Saugschuhs an die Umlenkstelle des Riemchens bzw der Siebtrommel bis zur Klemmlinie zwischen der Siebtrommel und der Unterwalze am Ende der Verdichtungszone geführt wird, kann gegebenenfalls auf eine sonst erforderliche Zentriervorrichtung für das Coregarn-Filament verzichtet werden. Das Coregarn-Filament wird dann immer in der Perforation zugeführt und trifft immer auf den in der Verdichtungszone zur Perforation gesaugten Faserverband.If the additional opening on the top of the suction shoe to the deflection point of the belt or the screen drum up to the nip line between the screen drum and the lower roller is guided at the end of the compression zone, optionally dispensed with an otherwise required centering device for the core yarn filament become. The coregarn filament is then always fed into the perforation and hits always on the in the compression zone sucked to the perforation fiber structure.

Sobald jedoch das Filament unter Spannung steht, was in manchen Fällen bei einem sogenannten "harten" Filament der Fall ist, kann auf die Zentriervorrichtung für das Coregarn-Filament nicht verzichtet werden, da der Unterdruck nicht ausreicht, um das Filament entgegen der Spannung zu führen.However, as soon as the filament is under tension, which in some cases at a so-called "hard" filament is the case, can on the centering device for the Coregarn filament can not be dispensed with, since the negative pressure is insufficient to the To lead filament against the tension.

Der Faserverband kann changiert werden. Hierbei wird eine Changierung des Faserverbandes durch das Ansaugen der Fasern auf die Perforation ermöglicht; die Position des Filaments wird nicht beeinflusst. Der Vorteil liegt darin, dass im Verzugsbereich eine Changierung ermöglicht wird, während die Zuordnung Filament und Faserverband am Verdichtungsriemchen realisiert wird und stets gleich ist, beispielsweise Filament und Faserverband mittig über der Perforation. Beim konventionellen Streckwerk muss die Position des Filaments dagegen bei der Changierung des Faserverbandes der Position des Faserverbandes angepasst werden.The fiber structure can be changed. This is a traversing of the fiber structure by sucking the fibers onto the perforation; the position of the Filaments will not be affected. The advantage is that in the drafting area a Traversing is enabled while assigning filament and fiber stranding at the Verdichtungsriemchen is realized and always the same, for example, filament and Fiber bandage in the middle above the perforation. With the conventional drafting system, the Position of the filament, however, when traversing the fiber structure of the position be adapted to the fiber structure.

Erfindungsgemäß besteht auch die Möglichkeit, die Konstruktion bei Verdichtungsaggregaten mit Siebbändern einzusetzen, welche keine Riemchen mit Perforationsspur verwenden, sondern auf ganzer Breite luftdurchlässig sind. Die Ansaugwirkung auf das Coregarn-Filament wird auch mit einer breiten Zusatzöffnung erreicht. Wenn in diesem Fall eine Zentrierwirkung angestrebt wird, muss die Zusatzöffnung entsprechend schmal, beispielsweise als Schlitz, ausgebildet sein.According to the invention, there is also the possibility of construction in compression units to use with screen belts, which no straps with perforation track use, but are permeable to air over its entire width. The suction on the Coregarn filament is also achieved with a wide additional opening. If in this If a centering effect is sought, the additional opening must be correspondingly narrow, for example, as a slot, be formed.

Die Erfindung lässt sich vorteilhafterweise auch beim Herstellen von sogenanntem SIROSPUN-Garn einsetzen. In diesem Fall ist das Verdichtungsnemchen, welches für die beiden getrennt zu verdichtenden Teil-Faserbänder zwei Perforationsspuren aufweist, erfindungsgemäß mit einer dritten Perforationsspur zwischen den beiden anderen Spuren ausgestattet, dem auf der Oberseite des Saugschuhs die zusätzliche Ansaugöffnung zugeordnet ist. Für Verdichtungseinrichtungen mit Siebtrommel gilt die entsprechende konstruktive Ausführung. Bei Verdichtungsvorrichtungen mit Siebband ist darüber hinaus ein weiterer Ansaugschlitz zwischen und vor denen für die beiden Teil-Faserbänder erforderlich.The invention can be advantageously also in the production of so-called Use SIROSPUN yarn. In this case, the compression bud, which is for the two partial fiber slivers to be compacted have two perforation traces, according to the invention with a third perforation track between the other two Traces equipped, on the top of the suction shoe, the additional intake assigned. For compaction equipment with screening drum, the corresponding applies constructive design. For compactors with a screen belt is in addition, another suction slot between and in front of those for the two partial fiber ribbons required.

Durch die zusätzliche Saugöffnung wird ständig Luft angesaugt, auch wenn sie nur jeweils kurzzeitig zum Einführen des Coregarn-Filaments benötigt wird. Um diesen unnötigen Aufwand zu vermeiden, kann erfindungsgemäß in die Absaugleitung der zusätzlichen Saugöffnung ein Absperrventil eingesetzt werden, welches über einen Bremsbetätigungshebel jeder Spindel der Spinnmaschine derart steuerbar ist, dass es nur beim Stillsetzen einer Spindel zum Beheben eines Fadenbruchs geöffnet wird. Through the additional suction opening air is constantly sucked, even if they only is required for a short time to introduce the core yarn filament. To this To avoid unnecessary effort, according to the invention in the suction of the additional suction opening a shut-off valve can be used, which has a Brake lever of each spindle of the spinning machine is controlled so that it only when stopping a spindle to resolve a yarn breakage is opened.
