Abstract
Description
Die Erfindung betrifft eine Vorrichtung an einer Spinnmaschine zum Verdichten eines Faserverbandes, mit einem aus einer angetriebenen Unterwalze und einer Oberwalze bestehenden Ausgangswalzenpaar eines Streckwerks, mit einer dem Ausgangswalzenpaar folgenden Verdichtungszone, mit einem den Faserverband durch die Verdichtungszone transportierenden, im Keilspalt des Ausgangswalzenpaares umgelenkten luftdurchlässigen Transportband, mit einem das Transportband mittels einer Gleitfläche führenden, nach Art einer Oberwalze angeordneten Saugkanal, mit wenigstens einem in der Gleitfläche angeordneten, vom Transportband abgedeckten und gegen die Unterwalze gerichteten Saugschlitz sowie mit einer an einer Lieferklemmlinie im Bereich des Endes der Verdichtungszone den Faserverband klemmenden und das Transportband antreibenden Lieferklemmlinie.The invention relates to a device on a spinning machine for compacting a fiber structure, with one consisting of a driven lower roller and an upper roller Output roller pair of a drafting system, with one of the output roller pair following compression zone, with a through the Compaction zone transporting, in the wedge gap of the pair of output rollers deflected breathable Conveyor belt, with a conveyor belt guiding the conveyor belt by means of a sliding surface, arranged in the manner of an upper roller suction channel, with at least one in the sliding surface arranged, covered by the conveyor belt and against the lower roller directed suction slot as well as with one on a delivery clamping line Clamping the fiber structure in the area of the end of the compression zone and the delivery clamping line driving the conveyor belt.
Wenn einem verstreckten Faserverband in unmittelbarem Anschluss an das Ausgangswalzenpaar eines Streckwerks ein Spinndrall erteilt wird, dann entsteht an der Ausgangsklemmlinie des Ausgangswalzenpaares ein so genanntes Spinndreieck. Dies rührt daher, dass der verstreckte Faserverband mit einer bestimmten Breite das Streckwerk verlässt und zu einem Faden relativ kleinen Durchmessers zusammengedreht wird. Das Spinndreieck enthält Randfasern, die nicht ordnungsgemäß in den verdrehten Faden eingebunden werden und somit wenig oder nichts zur Festigkeit des ersponnenen Fadens beitragen. Man ist daher in den letzten Jahren dazu übergegangen, der Verzugszone des Streckwerks eine so genannte Verdichtungszone nachzuordnen, die ihrerseits von einer Lieferklemmlinie auslaufseitig begrenzt wird. Erst danach wird dem Faden die Spinndrehung erteilt. In der Verdichtungszone werden die Fasern gebündelt oder verdichtet, wodurch der Faserverband beim Verlassen der Lieferklemmlinie so schmal ist, dass das gefürchtete Spinndreieck praktisch keine nachteiligen Auswirkungen mehr hat. Der ersponnene Faden wird dann gleichmäßiger, fester und weniger haarig.If a stretched fiber dressing in direct connection to the pair of output rollers of a drafting system a spin twist is given, then arises at the exit clamping line a so-called spinning triangle of the pair of output rollers. This is because that the stretched fiber structure with a certain width that Drafting system leaves and is twisted into a thread of relatively small diameter. The spinning triangle contains edge fibers, which are not properly in the twisted thread and thus little or nothing contribute to the strength of the spun thread. One is therefore in in recent years, a draft zone in the draft zone of the drafting system subordinate, which in turn bounded by a delivery terminal line on the outlet side becomes. Only then is the thread spun. In the Compression zone, the fibers are bundled or compressed, whereby the The fiber structure is so narrow when leaving the delivery clamping line that the dreaded Spinning triangle has practically no more adverse effects. The spun thread then becomes more even, firmer and less hairy.
Eine Vorrichtung der eingangs genannten
Art ist durch die
Der Erfindung liegt die Aufgabe zu Grunde, unter Beibehaltung der Vorteile der bekannten Vorrichtung dafür zu sorgen, dass sich der verdichtete Faserverband vor Erreichen der Lieferklemmlinie nicht mehr auflösen kann.The invention is based on the object Basically, while maintaining the advantages of the known device for that too ensure that the compacted fiber structure is before reaching the Do not dissolve the delivery clamp line can.
Die Aufgabe wird dadurch gelöst, dass die Gleitfläche an die Lieferunterwalze federnd angedrückt ist und mit dieser die Lieferklemmlinie bildet.The task is solved in that the sliding surface is resiliently pressed on the delivery lower roller and with this the Delivery pinch line forms.
Bei der Vorrichtung nach der Erfindung werden zunächst die Vorteile beibehalten, dass der Saugschlitz derjenigen Seite des Saugkanals abgewandt ist, die dem Wanderbläser zugänglich ist und wo sich insbesondere Faserflug absetzt. Hinzu kommen jedoch die Vorteile, dass der Saugschlitz jetzt bis in den Bereich der Lieferklemmlinie reicht und dass dadurch ein nachträgliches Auflösen des bereits verdichteten Faserverbandes nicht mehr geschieht. Außerdem gibt es im Bereich der Verdichtungszone eine Walze weniger als bei der bekannten Vorrichtung.In the device according to the invention be first maintain the advantages that the suction slit of that side facing away from the suction channel, which is accessible to the traveling blower and where in particular Fiber fly settles. Added to this, however, are the advantages of the suction slot now extends to the area of the delivery clamping line and that an afterthought Dissolve of the already compacted fiber structure no longer happens. Besides there there is one roller less in the area of the compression zone than in the known device.
In Ausgestaltung der Erfindung ist vorgesehen, dass ab dem Ausgangswalzenpaar des Streckwerks unter Umschlingung der Unterwalze die Laufrichtung des Faserverbandes um wenigstens 30° umgelenkt wird. Dadurch laufen die Fasern über die Unterwalze kontrolliert zum Saugschlitz, so dass die im Streckwerk erreichte Parallelität der Fasern nicht vor Erreichen der Verdichtungszone verloren geht. Dabei ist es günstig, wenn die Gleitfläche zwischen der Unterwalze des Ausgangswalzenpaares und der Lieferunterwalze in Laufrichtung des Faserverbandes gekrümmt ist. Dadurch kann sich das Transportband satt an die Gleitfläche und den Saugschlitz anlegen, so dass das Eindringen von Falschluft, verbunden mit einer Verschlechterung des Wirkungsgrades, vermieden wird.In an embodiment of the invention provided that from the pair of output rollers of the drafting system under Wrapping the lower roller the direction of the fiber structure deflected by at least 30 ° becomes. This causes the fibers to overflow the lower roller controls to the suction slot, so that in the drafting system parallelism achieved the fibers are not lost before reaching the compression zone. there is it convenient if the sliding surface between the lower roller of the pair of output rollers and the delivery lower roller is curved in the direction of the fiber structure. This can place the conveyor belt snugly against the sliding surface and the suction slot, so that the intrusion of false air, associated with deterioration efficiency, is avoided.
Vorteilhaft ist die Lieferunterwalze nach Art einer Druckwalze mit einem elastischen Bezug versehen. Dies führt nicht nur zu einer günstigen Drallstoppwirkung ohne allzu kräftigen Andruck der Gleitfläche an die Lieferunterwalze, sondern gleichzeitig zu einer guten Friktionsmitnahme für den Antrieb des Transportbandes.The delivery lower roller is advantageous provided with an elastic cover like a pressure roller. this leads to not just a cheap one Swirl stop effect without too strong Pressure of the sliding surface to the delivery lower roller, but at the same time to ensure good friction for the Drive of the conveyor belt.
Der Antrieb der Lieferunterwalze kann ohne Weiteres von der Unterwalze des Ausgangswalzenpaares des Streckwerks abgeleitet werden. Zweckmäßiger ist es jedoch, wenn die Lieferunterwalze als Zwischenwalze ausgebildet und von einem gesonderten angetriebenen Unterzylinder antreibbar ist. Dadurch lässt sich auch innerhalb der Verdichtungszone ein geringer Verzug des Faserverbandes kontrolliert einstellen.The drive of the delivery lower roller can easily from the lower roller of the pair of output rollers Drafting system can be derived. However, it is more convenient if the Delivery lower roller designed as an intermediate roller and by a separate driven lower cylinder is drivable. This allows A slight warping of the fiber structure also within the compression zone set in a controlled manner.
Damit zu Wartungszwecken der Saugkanal leicht von der Lieferunterwalze wegbewegt werden kann, ist es vorteilhaft, wenn der Saugkanal in einem die Oberwalze des Ausgangswalzenpaares des Streckwerks halternden Belastungsträger angeordnet ist. Analog den bekannten Druckwalzenzwillingen kann sich der Saugkanal dabei über zwei benachbarte Spinnstellen erstrecken. Man erhält dann den zusätzlichen Vorteil, dass wegen der Kürze des Saugkanals endlose Transportbänder verwendet werden können, falls diese bei Verschleiß ausgewechselt werden müssen.So the suction channel for maintenance purposes can easily be moved away from the delivery lower roller, it is advantageous if the suction channel is arranged in a load carrier holding the upper roller of the pair of output rollers of the drafting system. Analogous to the known pressure roller twins, the suction channel can extend over two adjacent spinning positions. This gives the additional advantage that, due to the shortness of the suction channel, endless conveyor belts can be used if they have to be replaced when worn.
In besonders vorteilhafter Ausgestaltung der Erfindung ist vorgesehen, dass das Transportband an der Oberwalze des Ausgangswalzenpaares streifend anliegt. Da das Transportband und die Oberwalze an der Berührungsstelle gegenläufig sind, wird etwa am Transportband anhaftender Faserflug bei Betrieb ständig abgestreift. Dabei ist es günstig, wenn am Saugkanal ein das Transportband an die Oberwalze andrückendes Federelement vorgesehen ist, welches zugleich als Spannelement für das Transportband ausgebildet sein kann.In a particularly advantageous embodiment the invention provides that the conveyor belt on the top roller of the pair of output rollers grazes. Because the conveyor belt and the top roller at the point of contact opposite are, for example, fiber fly adhering to the conveyor belt during operation constantly stripped. It is beneficial if on the suction channel press the conveyor belt against the top roller Spring element is provided, which also serves as a tensioning element for the conveyor belt can be trained.
