Description

Beschreibung:Description:
ZentrifugenspinnvorrichtungCentrifugal spinning device
Im Zusammenhang mit der Herstellung von Stapelfasergarnen sind verschiedene Spinnverfahren bekannt.Various spinning processes are known in connection with the production of staple fiber yarns.
Neben dem Ringspinnen und dem Rotorspinnen ist beispielsweise das Zentrifugenspinnen ein seit langem bekanntes Spinnverfahren .In addition to ring spinning and rotor spinning, centrifugal spinning, for example, is a long-known spinning process.
Beim Zentrifugenspinnen unterscheidet man dabei grundsätzlich zwischen zwei verschiedenen Spinnarten, dem sogenannten Einstufen-Spinnen und dem sogenannten Zweistufen-Spinnen.In centrifugal spinning, a basic distinction is made between two different types of spinning, the so-called one-step spinning and the so-called two-step spinning.
Bei beiden Spinnarten wird zunächst ein Vorlagematerial, entweder ein in einer Spinnkanne bevorratetes Faserband oder eine als Vorgarnspule bereitliegende Faserlunte in einem Streckwerk, der gewünschten Garnfeinheit entsprechend, verzogen und über ein axial verschiebbar gelagertes Fadenfuhrerrohr in ein mit hoher Drehzahl umlaufendes Zentrifugenspinnelement befördert .In both types of spinning, a feed material, either a fiber sliver stored in a spinning can or a sliver of fiber as a roving bobbin, is warped in a drafting system in accordance with the desired yarn fineness and conveyed via an axially displaceably mounted thread guide tube into a centrifugal spinning element rotating at high speed.
Das aus der Mündung des Fadenführerrohres austretende Vorlagematerial legt sich dabei, unter Bildung eines Garnschenkels, an die Zentrifugeninnenwandung an und wird von dieser mitgenommen.The feed material emerging from the mouth of the thread guide tube lies against the inner wall of the centrifuge, forming a thread leg, and is carried along by it.
Das heißt, das Fasermaterial erhält durch die Rotation des mit dem Zentrifugenspinnelement Umlaufenden . Garnschenkels eine Drehung.This means that the fiber material is obtained by the rotation of the one rotating with the centrifuge spinning element. Twine a turn.
Der durch die Drehungserteilung entstehende Faden wird durch das Fadenfuhrerrohr, das changierbar und axial verschiebbar gelagert ist, an der Zentrifugeninnenwandung abgelegt und bildet dort einen Garnkörper, einen sogenannten Spinnkuchen.The thread created by the rotation is made changeable and axially displaceable by the thread guide tube is stored on the inner wall of the centrifuge and forms a package, a so-called spinning cake.
Beim Einstufen-Spinnen sind die Zentrifugendrehzahl und die Liefergeschwindigkeit des Vorlagematerials dabei so aufeinander abgestimmt, daß der als Spinnkuchen abgelegte Faden bereits seine endgültige Drehung aufweist und in einem nachfolgenden Arbeitsgang auf eine, beispielsweise auf dem Fadenfuhrerrohr bereitgehaltene oder von unten in das Zentrifugenspinnelement eingeführte Umspulhülse umgewickelt werden kann.In single-stage spinning, the centrifuge speed and the delivery speed of the stock material are matched to one another in such a way that the thread deposited as a spinning cake already has its final rotation and is wound in a subsequent operation onto a winding tube, for example held on the thread guide tube or inserted into the centrifuge spinning element from below can be.
Die bei diesen Umspulvorgängen entstehenden Spinnkopse werden später mittels einer im Produktionsablauf nachgeschalteten Spulmaschine zu großvolumigen Kreuzspulen umgespult.The spinning bobbins created during these rewinding processes are later rewound into large-volume cross-wound bobbins by means of a winder connected downstream in the production process.
Im Zusammenhang mit dem Zentrifugenspinnen sind aber nicht nur zwei unterschiedliche Spinnverfahren bekannt, sondern auch eine Vielzahl zum Teil recht unterschiedlich aufgebauter Spinnvorrichtungen .In connection with centrifugal spinning, however, not only are two different spinning processes known, but also a large number of spinning devices, some of which have very different structures.
In der DE 42 08 039 AI ist beispielsweise eineIn DE 42 08 039 AI, for example
Zentrifugenspinnvorrichtung beschrieben, die ein rohrförmiges, in Magnetlagern abgestütztes Zentrifugenspinnelement aufweist, das über einen mittig angeordneten elektromagnetischen Zentrifugenantrieb verfügt.Centrifuge spinning device described, which has a tubular, supported in magnetic bearings centrifuge spinning element, which has a centrally arranged electromagnetic centrifuge drive.
Derartig gestaltete Zentrifugenspinnvorrichtungen sind sowohl von oben als auch von unten her gut zugängig, so daß eine Umspulhülse entweder, wie in der DE 42 08 039 AI dargestellt, von unten in die Zentrifugenspinnelement eingeführt werden kann oder, wie beispielsweise in der DE 195 23 835 AI beschrieben, auf dem Fadenfuhrerrohr verschiebbar angeordnet ist und dann von oben in das Zentrifugenspinnelement eingeführt wird.Centrifuge spinning devices designed in this way are easily accessible both from above and from below, so that a winding tube can either be inserted into the centrifuge spinning element from below, as shown in DE 42 08 039 AI, or, for example, in DE 195 23 835 AI described, slidably arranged on the thread guide tube and is then inserted into the centrifuge spinning element from above.
Obwohl solche rohrförmigen Spinnzentrifugen gut zugängig sind, weisen sie den erheblichen Nachteil auf, daß sie aufgrund ihrer Bauart einen verhältnismäßig hohen Energieverbrauch haben.Although such tubular spinning centrifuges are easily accessible, they have the considerable disadvantage that their design means that they have a relatively high energy consumption.
Das heißt, die Lage des Antriebes, dessen Rotor das rohrförmige Zentrifugenspinnelement im Bereich des größtenThat is, the position of the drive, the rotor of which is the tubular centrifuge spinning element in the area of the largest
Durchmessers umfaßt, führt zu einem relativ ungünstigenDiameter includes, leads to a relatively unfavorable
Energieeinsatz .Use of energy.
Ein deutlich günstigerer Energieeinsatz ergibt sich, wenn eine sogenannte TopfZentrifuge zum Einsatz kommt, das heißt, wenn eine Zentrifugenspinnelement verwendet wird, das einen halsartigen Ansatz aufweist, an dem der elektromagnetische Antrieb der Spinnzentrifuge installiert ist.A significantly cheaper use of energy is obtained when a so-called pot centrifuge is used, i.e. when a centrifuge spinning element is used that has a neck-like attachment on which the electromagnetic drive of the spinning centrifuge is installed.
Eine derartig aufgebaute Spinnzentrifuge ist beispielsweise durch die WO-98/11 284 bekannt.Such a spinning centrifuge is known for example from WO-98/11 284.
Bei dieser bekannten Zentrifugenspinnvorrichtung wird die Umspulhülse durch eine dem Zentrifugenhals gegenüberliegende Zentrifugenöffnung in das Zentrifugenspinnelement eingeführt und der fertige Spinnkops durch dieselbe Zentrifugenöffnung entnommen.In this known centrifuge spinning device, the rewinding sleeve is inserted into the centrifuge spinning element through a centrifuge opening opposite the centrifuge neck and the finished spinning cop is removed through the same centrifuge opening.
Um ein ordnungsgemäßes Umspulen des auf der Innenwandung des Zentrifugenspinnelementes abgelegten Garnkörpers auf die in eine Umspulstellung eingefahrene Umspulhülse zu gewährleisten, erfolgt bei diesen bekannten Zentrifugenspinnvorrichtungen die Ablage des Spinnkuchens von unten nach oben.In order to ensure proper rewinding of the yarn package deposited on the inner wall of the centrifuge spinning element onto the rewinding sleeve moved into a rewinding position, the spinning cake is deposited from bottom to top in these known centrifuge spinning devices.
Das heißt, am Ende des Spinnprozesses wird der Umspulvorgang durch die Umspulhülse dann eingeleitet, wenn das Fadenfuhrerrohr seine obere Endposition in der Nähe des Spinnzentrifugenbodens erreicht hat.That is, at the end of the spinning process, the rewinding process is initiated by the rewinding tube when that Thread guide tube has reached its upper end position near the bottom of the spinning centrifuge.
Der Garnkörper wird in diesem Fall von oben nach unten, das heißt, an der Hülsenspitze beginnend, auf die Umspulhülse umgewickelt .In this case, the package is wound from top to bottom, that is, starting at the tube tip, onto the winding tube.
Bei derartigen Zentrifugenspinnvorrichtungen ergeben sich allerdings große Schwierigkeiten, wenn es während des Umspulvorganges zu einem sogenannten Wickelbruch kommt. In einem solchen Fall verhindert oft der im unteren Bereich noch an der Innenwandung des Zentrifugenspinnelementes anhaftende Garnkörperrest, daß die bereits teilweise bewickelte Umspulhülse aus dem Zentrifugenspinnelement entnommen werden kann.In such centrifuge spinning devices, however, there are great difficulties if a so-called winding break occurs during the rewinding process. In such a case, the remnant of twine still adhering to the inner wall of the centrifugal spinning element in the lower region often prevents the partially wound winding tube from being removed from the centrifugal spinning element.
Das bedeutet, in einem solchen Fall muß die betreffende Spinnzentrifuge gestoppt und zunächst gereinigt werden.This means that in such a case the spinning centrifuge in question must be stopped and cleaned first.
Als nachteilig haben sich bei diesen bekannten Zentrifugenspinnvorrichtung außerdem die hergestellten Spinnkopse erwiesen, da sich die Bewicklungsrichtung derartiger Spinnkopse von Spinnkopsen unterscheidet, die auf Ringspinnmaschinen hergestellt wurden.The spinning heads produced have also proven to be disadvantageous in these known centrifuge spinning devices, since the winding direction of such spinning heads differs from spinning heads which were produced on ring spinning machines.
Da die Vorbereitungseinrichtung der im Produktionsprozeß nachgeschalteten Kreuzspulautomaten in der Regel auf Ringspinnkopse eingestellt sind, bereitet die Vorbereitung derartiger Zentrifugenspinnkopse oft größere Schwierigkeiten.Since the preparation device of the cross winding machines connected downstream in the production process are generally set to ring spinning bobbins, the preparation of such centrifuge spinning bobbins often presents greater difficulties.
Ausgehend vom vorgenannten Stand der Technik liegt der Erfindung die Aufgabe zugrunde, eineStarting from the aforementioned prior art, the invention has for its object a
Zentrifugenspinnvorrichtung zu schaffen, die die vorgenannten Nachteile nicht aufweist und die insbesondere die Fertigung von Spinnkopsen ermöglicht, die sich von Ringspinnkopsen kaum unterscheiden .To create centrifugal spinning device that does not have the aforementioned disadvantages and in particular the manufacture enabled by spinning bobbins that hardly differ from ring spinning bobbins.
Diese Aufgabe wird erfindungsgemäß mit einer Spinnvorrichtung gelöst, wie sie im Anspruch 1 beschrieben ist.This object is achieved with a spinning device as described in claim 1.
Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche .Advantageous embodiments of the invention are the subject of the dependent claims.
Mit der erfindungsgemäßen Spinnvorrichtung ist es auf einfache Weise gelungen, die Nachteile der bekannten Spinnvorrichtungen zu vermeiden.With the spinning device according to the invention, it has been possible in a simple manner to avoid the disadvantages of the known spinning devices.
Das heißt, die nach dem Umspulvorgang vorliegenden Spinnkopse sind beispielsweise wie Spinnkopse aufgebaut, die auf einer Ringspinnmaschine gefertigt wurden und können daher problemlos mit der herkömmlichen Spultechnologie bearbeitet werden. Des weiteren bleibt bei der erfindungsgemäß gestalteten Zentrifugenspinnvorrichtung die zuletzt abgelegte Garnlage des Spinnkuchens jederzeit erreichbar, so daß im Bedarfsfall, beispielsweise nach einem Fadenbruch während des Spinnprozesses oder einem Wickelbruch während des Umspulvorganges, jederzeit eine externe Einleitung des Umspulvorganges möglich ist.This means that the spinning bobbins that are present after the rewinding process are constructed, for example, like spinning bobbins that were produced on a ring spinning machine and can therefore be processed without problems using conventional winding technology. Furthermore, in the centrifuge spinning device designed according to the invention, the last deposited yarn layer of the spin cake can be reached at any time, so that an external initiation of the rewinding process is possible at any time, for example after a thread break during the spinning process or a winding break during the rewinding process.
Das sich bei einer solchen externen Einleitung des Umspulvorganges einstellende Faden-Nebensystem ist dabei relativ kurz, so daß der entstandene Spinnkops anschließend auf der Spulmaschine meist ohne Rest abspulbar ist. Der nach einer externen Einleitung des Umspulvorganges entstandene Spinnkops kann außerdem stets problemlos aus dem Zentrifugenspinnelement entnommen werden. Das heißt, ein aufgrund eines Wickelbruches noch im Zentrifugenspinnelement verbliebener Garnkörperrest stört den Doffvorgang des Spinnkopses in keiner Weise und bleibt für eine eventuelle nachfolgende, zweite externe Einleitung eines Umspulvorganges erreichbar.The thread secondary system that occurs with such an external initiation of the rewinding process is relatively short, so that the resulting spinning cop can then usually be unwound without residue on the winding machine. The spinning cop created after an external initiation of the rewinding process can also always be easily removed from the centrifuge spinning element. This means that a package residue remaining in the centrifugal spinning element due to a winding break does not in any way disturb the doffing process of the spinning cop and remains accessible for a possible subsequent, second external initiation of a rewinding process.
Wie im Anspruch 2 dargelegt, ist in vorteilhafter Ausführungsform eine Sensoreinrichtung vorgesehen, die das laufende Vorlagematerial überwacht.As set out in claim 2, in an advantageous embodiment, a sensor device is provided, which monitors the current document material.
Die Sensoreinrichtung, die vorzugsweise zwischen Streckwerk und Fadenfuhrerrohr positioniert ist, ist über eine Signalleitung an eine entsprechende Steuereinrichtung, vorzugsweise einen Arbeitsstellenrechner, angeschlossen, so daß im Falle eines Fadenbruches dafür gesorgt wird, daß beispielsweise die weitere Zufuhr von Fasermaterial in das Zentrifugenspinnelement unterbrochen sowie ein Umspulvorgang eingeleitet wird.The sensor device, which is preferably positioned between the drafting device and the thread guide tube, is connected via a signal line to a corresponding control device, preferably a workstation computer, so that in the event of a thread breakage it is ensured that, for example, the further supply of fiber material into the centrifugal spinning element is interrupted and one Rewinding is initiated.
In alternativer Ausführungsform kann die Sensoreinrichtung allerdings auch, wie im Anspruch 3 beschrieben, unterhalb des Zentrifugenspinnelementes angeordnet sein und überwacht dann den rotierenden Garnschenkel.In an alternative embodiment, however, as described in claim 3, the sensor device can also be arranged below the centrifuge spinning element and then monitors the rotating yarn leg.
Auch in diesem Fall steht die Sensoreinrichtung über eine Signalleitung mit dem Arbeitsstellenrechner in Verbindung, der dafür sorgt, daß im Falle eines Fadenbruches die Zufuhr von Fasermaterial in das Zentrifugenspinnelement gestoppt und ein Umspulvorgang eingeleitet wird.In this case too, the sensor device is connected to the workstation computer via a signal line, which ensures that in the event of a thread break, the supply of fiber material into the centrifuge spinning element is stopped and a rewinding process is initiated.
Wie im Anspruch 4 beschrieben, ist in bevorzugter Ausführungsform außerdem eine Fadenlöseeinrichtung vorhanden, die definiert an den Wickelkegel des Garnkörpers anstellbar ist und dabei den Umspulvorgang des mit der Zentrifuge rotierenden Garnkörpers auf die auf dem Fadenfuhrerrohr angeordnete, in der Umspulstellung bereitstehende Umspulhülse startet.As described in claim 4, a thread release device is also present in a preferred embodiment, which can be adjusted in a defined manner to the winding cone of the package and thereby the rewinding of the package rotating with the centrifuge onto that on the thread guide tube arranged rewinding sleeve ready in the rewinding position starts.
Die Fadenlöseeinrichtung kommt sowohl nach einem Fadenbruch während des Spinnprozesses als auch nach einem Wickelbruch während des Umspulvorganges zum Einsatz.The thread release device is used both after a thread break during the spinning process and after a winding break during the rewinding process.
In beiden Fällen wird die Fadenlöseeinrichtung an denIn both cases, the thread release device to the
Wickelkegel des mit der Spinnzentrifuge rotierendenWinding cone of the rotating with the spinning centrifuge
Garnkörpers angestellt und damit ein Umspulvorgang eingeleitet .Twine turned on and thus initiated a rewinding process.
In vorteilhafter Ausführungsform ist des weiteren vorgesehen, daß das Doffen des gefertigten Spinnkopses durch die dem Zentrifugenhals gegenüberliegende Zentrifugenöffnung erfolgt (Anspruch 5) .In an advantageous embodiment it is further provided that the doffing of the finished spinning cop takes place through the centrifuge opening opposite the centrifuge neck (claim 5).
Auf diese Weise kann der Halsbereich desIn this way, the neck area of the
Zentrifugenspinnelementes relativ klein gehalten werden, was sich insbesondere auf den Energieverbrauch der Spinneinrichtung positiv auswirkt.Centrifuge spinning element can be kept relatively small, which has a positive effect in particular on the energy consumption of the spinning device.

Solche Zentrifugenspinnvorrichtungen 1 besitzen vorzugsweise ein in einem Spinngehäuse 2 rotierbar gelagertes Zentrifugenspinnelement 3, das in Lagern 4 abgestützt ist und über einen elektromagnetischen Antrieb 5 einzelmotorisch angetrieben wird.Such centrifuge spinning devices 1, which are equipped with a so-called pot centrifuge, are known in principle and are described in relatively detail, for example, in WO-98/11 284. Such centrifuge spinning devices 1 preferably have a centrifuge spinning element 3 rotatably mounted in a spinning housing 2, which is supported in bearings 4 and is driven by a single motor via an electromagnetic drive 5.
Die Lager 4 sind dabei vorzugsweise als Magnetlager, beispielsweise als Permanentmagnetlager, ausgebildet.The bearings 4 are preferably designed as magnetic bearings, for example as permanent magnet bearings.
Die Zentrifugenspinnvorrichtung 1 verfügt des weiteren über ein in das Zentrifugenspinnelement 3 einführbares Fadenfuhrerrohr 7. An das Fadenfuhrerrohr 7 ist ein lediglich schematisch angedeuteter Antrieb 8 angeschlossen, der dem Fadenfuhrerrohr 7 eine Changierbewegung erteilt und das Fadenfuhrerrohr 7 gleichzeitig bezüglich des Zentrifugenspinnelementes 3 axial verlagert.The centrifuge spinning device 1 also has a thread guide tube 7 which can be inserted into the centrifuge spinning element 3. A drive 8, which is only indicated schematically, is connected to the thread guide tube 7, which gives the thread guide tube 7 a traversing movement and at the same time axially displaces the thread guide tube 7 with respect to the centrifuge spinning element 3.
Auf dem Fadenfuhrerrohr 7 ist, beispielsweise an der hohlen Kolbenstange eines das Fadenfuhrerrohr 7 umgebenden Pneumatikzylinders 10 eine Umspulhülse 9 verschiebbar gelagert. Der Pneumatikzylinder 10 ist dabei über eine entsprechende Pneumatikleitung, in die ein Ventil, beispielsweise ein 2/2-Wegeventil 22 eingeschaltet ist, an eine (nicht dargestellte) Druckluftquelle angeschlossen. Wie in der Figur dargestellt ist das Ventil 22 über eine Steuerleitung 21 mit dem Arbeitsstellenrechner 19 verbunden.A winding sleeve 9 is slidably mounted on the thread guide tube 7, for example on the hollow piston rod of a pneumatic cylinder 10 surrounding the thread guide tube 7. The pneumatic cylinder 10 is connected via a corresponding pneumatic line, in which a valve, for example a 2/2-way valve 22, is connected to a compressed air source (not shown). As shown in the figure, the valve 22 is connected to the workstation computer 19 via a control line 21.
Wie in der Figur angedeutet, ist die Umspulhülse 9 während des regulären Spinnprozesses über den Pneumatikzylinder 10 , bezüglich des Fadenführerrohres 7 in einer Ruhestellung 11 fixiert und kann, beispielsweise zur Einleitung des Umspulvorganges, in eine gestrichelt angedeutete Umspulstellung 12 verlagert werden. Des weiteren weist die Zentrifugenspinnvorrichtung 1 eine Sensoreinrichtung 13 zum Detektieren eines Fadenbruches auf.As indicated in the figure, the rewinding sleeve 9 is fixed in a rest position 11 with respect to the thread guide tube 7 during the regular spinning process via the pneumatic cylinder 10 and can be shifted into a rewinding position 12 indicated by dashed lines, for example to initiate the rewinding process. Furthermore, the centrifuge spinning device 1 has a sensor device 13 for detecting a thread break.
Die Sensoreinrichtung 13, die das laufende Vorlagematerial 18 überwacht, ist in bevorzugter Ausführungsform unterhalb des Streckwerkes 6 positioniert und über eine Signalleitung 20 an eine spinnstelleneigene Steuereinrichtung 19 angeschlossen.In a preferred embodiment, the sensor device 13, which monitors the current feed material 18, is positioned below the drafting system 6 and connected to a control device 19 belonging to the spinning station via a signal line 20.
Ein alternative Ausführungsform einer solchen Sensoreinrichtung ist in der Figur gestrichelt dargestellt. Die Sensoreinrichtung 13A, die über eine Signalleitung 20A ebenfalls an den Arbeitsstellenrechner angeschlossen ist, ist dabei zum Beispiel als Lichttaster ausgebildet und überwacht den Umlauf des rotierenden Garnschenkels 28.An alternative embodiment of such a sensor device is shown in dashed lines in the figure. The sensor device 13A, which is also connected to the workstation computer via a signal line 20A, is designed, for example, as a light sensor and monitors the rotation of the rotating yarn leg 28.
Zum Einleiten des Umspulvorganges, beispielsweise nach einem Fadenbruch während des Spinnprozesses oder nach einem Wickelbruch während des Umspulvorganges, ist außerdem ein Fadenlöseelement 14 vorgesehen.To initiate the rewinding process, for example after a thread break during the spinning process or after a winding break during the rewinding process, a thread release element 14 is also provided.
Das Fadenlöseelement 14 besitzt dabei eine an den Wicklungskegel 29 des Garnkörpers 15 anstellbare Schneide 16 sowie eine die Schneide 16 in axialer Richtung überfassende Fadenleitkontur 17, die über einen Antrieb 23 parallel zur Zentrifugeninnenwandung 25 verlagerbar sind. Wie aus der Figur ersichtlich ist der Antrieb 23 des Fadenlöseelementes 14 über eine Steuerleitung 30 mit der spinnstelleneigenen Steuereinrichtung 19, dem sogenannten Arbeitsstellenrechner, verbunden und kann über diesen definiert angesteuert werden. Funktion der Einrichtung:The thread release element 14 has a cutting edge 16 which can be adjusted to the winding cone 29 of the package 15 and a thread guide contour 17 which encompasses the cutting edge 16 in the axial direction and which can be displaced parallel to the inner wall 25 of the centrifuge via a drive 23. As can be seen from the figure, the drive 23 of the thread releasing element 14 is connected via a control line 30 to the spinning station's own control device 19, the so-called work station computer, and can be controlled in a defined manner via this. Function of the facility:
Einer oberhalb des Zentrifugenspinnelementes 3 angeordneten Faserband-Verzugseinrichtung, beispielsweise einem Streckwerk 6, wird aus einer (nicht dargestellten) Spinnkanne ein Faserband oder von einer (ebenfalls nicht dargestellten) Flyerspule ein Vorlagematerial 18 zugeführt. Das Vorlagematerial 18, beispielsweise ein Vorgarn, wird entsprechend der gewünschten Feinheit verzogene und über das Fadenfuhrerrohr 7 in das Zentrifugenspinnelement 3 geleitet, wo es sich unter Bildung eines rotierenden Garnschenkels 28 an die Innenwandung 25 des umlaufendenA sliver drafting device, for example a drafting device 6, arranged above the centrifuge spinning element 3, is fed a sliver from a spinning can (not shown) or a feed material 18 from a flyer spool (also not shown). The original material 18, for example a roving, is warped in accordance with the desired fineness and passed via the thread guide tube 7 into the centrifuge spinning element 3, where it forms a rotating thread leg 28 on the inner wall 25 of the rotating one
Zentrifugenspinnelementes 3 anlegt und dabei eine Drehung erhält .Centrifuge spinning element 3 creates and thereby receives a rotation.
Das heißt, der aufgrund dieser Drehung entstehende Faden wird durch das Fadenfuhrerrohr 7 so auf der Innenwandung 25 des Zentrifugenspinnelement 3 positioniert, daß ein definierter Garnkörper, ein sogenannter Spinnkuchen 15 entsteht. Während des Spinnprozesses und damit während der Erstellung des Garnkörpers 15, die im Bereich des Zentrifugenbodens 26 des Zentrifugenspinnelementes 3 beginnt, wird das Fadenfuhrerrohr 7 über den Antrieb 8 oszillierend auf und ab bewegt und gleichzeitig kontinuierlich in Richtung der Zentrifugenöffnung 27 abgesenkt.This means that the thread resulting from this rotation is positioned by the thread guide tube 7 on the inner wall 25 of the centrifuge spinning element 3 in such a way that a defined yarn package, a so-called spin cake 15, is produced. During the spinning process and thus during the production of the package 15, which begins in the region of the centrifuge bottom 26 of the centrifuge spinning element 3, the thread guide tube 7 is moved up and down in an oscillating manner via the drive 8 and at the same time is continuously lowered in the direction of the centrifuge opening 27.
Der gesponnene Faden wird dadurch nach Art einer sogenannten Kopswicklung an der Innenwandung 25 des Zentrifugenspinnelementes 3 zwischengespeichert.The spun thread is thereby temporarily stored in the manner of a so-called cop winding on the inner wall 25 of the centrifuge spinning element 3.
Wenn der Garnkörper 15 eine bestimmte, einstellbare Größe erreicht hat, wird ein Umspulvorgang eingeleitet. Das heißt, das Fadenführerohr 7 wird durch den Antrieb 8 zunächst in den nächsten oberen Totpunkt seines Changierhubes gefahren und anschließend die Umspulhülse 6 durch denWhen the package 15 has reached a certain, adjustable size, a rewinding process is initiated. This means that the thread guide tube 7 is initially driven to the next top dead center of its traversing stroke by the drive 8 driven and then the winding tube 6 through the
Pneumatikzylinder 10 aus einer Ruhestellung 11 in einePneumatic cylinder 10 from a rest position 11 in a
Umspulstellung 12 im Bereich des rotierenden Garnschenkels 28 verlagert .Rewinding position 12 shifted in the region of the rotating yarn leg 28.
Beim Kreuzen des rotierenden Garnschenkels 28 wird der Faden an der Umspulhülse 9 festgelegt und damit den Umspulvorgang ausgelöst .When crossing the rotating yarn leg 28, the thread is fixed on the rewinding sleeve 9 and thus the rewinding process is triggered.
Gleichzeitig wird über die Steuereinrichtung 19 eine imAt the same time is a in the control device 19
Bereich des Streckwerkes 6 angeordnete (nicht dargestellte)Area of the drafting system 6 (not shown)
Luntenstoppeinrichtung angesteuert, die die weitere Zufuhr vonMatch stop device controlled, which the further supply of
Vorgarn 18 unterbricht.Roving 18 interrupts.
Der durch das Umspulen entstandene Spinnkops wird anschließend über die Zentrifugenöffnung 27 gedofft und beispielsweise einer nachgeschalteten Spulmaschine zugeführt.The spinning cop resulting from the rewinding is then doped via the centrifuge opening 27 and fed, for example, to a downstream winder.
Wenn es während des Spinnprozesses zu einem Fadenbruch kommt, wird ein solcher Fadenbruch durch die Sensoreinrichtung 13 bzw. 13A sofort erfaßt und über die Signalleitung 20 bzw. 20A unmittelbar an die Steuereinrichtung 19 gemeldet. Die Steuereinrichtung 19 aktiviert daraufhin unverzüglich die Luntenstoppvorrichtung und sorgt außerdem dafür, das das Fadenfuhrerrohr 7 in den nächsten oberen Totpunkt seines Changierhubes verlagert wird.If a thread break occurs during the spinning process, such a thread break is immediately detected by the sensor device 13 or 13A and reported directly to the control device 19 via the signal line 20 or 20A. The control device 19 then immediately activates the match stop device and also ensures that the thread guide tube 7 is shifted to the next top dead center of its traversing stroke.
Anschließend aktiviert die Steuereinrichtung 19 über eine Signalleitung 21 das Wegeventil 22 und über eine Signalleitung 30 den Antrieb 23 der Fadenlöseeinrichtung 14. Das Wegeventil 22 sorgt dann dafür, daß der Pneumatikzylinder 10 die Umspulhülse 9 aus ihrer Ruhestellung 11 in ihre Umspulposition 12 schiebt, während der Antrieb 23 die Fadenlöseeinrichtung 14 parallel zur Innenwandung 25 in das Zentrifugenspinnelement 3 einfährt. Die Fadenlöseeinrichtung 14 legt sich schließlich mit ihrer Schneide 16 an den Wicklungskegel 29 des Garnkörpers 15. Beim Anlegen der Schneide 16 an den Wicklungskegel 29 löst sich aus dem mit dem Zentrifugenspinnelement 3 rotierenden Garnkörper 15 eine Fadenschlinge heraus, die sich um die Umspulhülse 9 wickelt und damit den Umspulvorgang einleitet. Obwohl die Schneide 16 der Fadenlöseeinrichtung 14 nahe an der Innenwandung 25 des Zentrifugenspinnelementes 3 angreift, ist es dabei allerdings nicht immer zu vermeiden, daß einige Wicklungslagen des Spinnkuchens 15 unterhalb der Schneide 16 angeordnet sind. Diese Wicklungslagen werden während des Umwickelvorganges durch die Fadenleitkontur 17 in Richtung der Umspulhülse 9 angehoben und an diese übergeben. Auf diese Weise wird vermieden, daß das Fadenlöseelement 14 überwickelt wird.The control device 19 then activates the directional control valve 22 via a signal line 21 and the drive 23 of the thread release device 14 via a signal line 30. The directional control valve 22 then ensures that the pneumatic cylinder 10 pushes the rewinding sleeve 9 out of its rest position 11 into its rewinding position 12 during the Drive 23 moves the thread releasing device 14 into the centrifuge spinning element 3 parallel to the inner wall 25. The thread release device 14 finally lies with its cutting edge 16 on the winding cone 29 of the package 15. When the cutting edge 16 is placed on the winding cone 29, a thread loop is released from the package 15 rotating with the centrifugal spinning element 3, which winds around the winding tube 9 and thus initiating the rewinding process. Although the cutting edge 16 of the thread releasing device 14 engages close to the inner wall 25 of the centrifuge spinning element 3, it cannot always be avoided that some winding layers of the spinning cake 15 are arranged below the cutting edge 16. These winding layers are raised during the winding process by the thread guide contour 17 in the direction of the winding tube 9 and transferred to the latter. In this way it is avoided that the thread release element 14 is wound over.
Bei diesem Umspulvorgang wird der ursprünglich an der Innenwandung 25 des Zentrifugenspinnelementes 3 abgelegte Garnkörper 15 auf die in der Umspulstellung 12 bereitstehende Umspulhülse 9 umgewickelt und bildet dabei einen Spinnkops.In this rewinding operation, the yarn body 15 originally deposited on the inner wall 25 of the centrifuge spinning element 3 is wound onto the rewinding sleeve 9 provided in the rewinding position 12 and thereby forms a spinning cop.
Der (nicht dargestellte) Spinnkops wird anschließend durch die Zentrifugenöffnung 27 entnommen und zur Weiterverarbeitung an eine nachgeordnete Textilmaschine, vorzugsweise eine Spulmaschine übergeben.The spinning cop (not shown) is then removed through the centrifuge opening 27 and transferred to a downstream textile machine, preferably a winder, for further processing.
Die Fadenlöseeinrichtung 14 kommt auch zum Einsatz, wenn es während des Umspulvorganges zu einem Wickelbruch gekommen ist. Das heißt, wenn nur ein Teil des Garnkörpers 15 auf die Umspulhülse 9 umgewickelt werden konnte. Auch in einem solchen Fall wird nachdem der teilweise bewickelte Spinnkops gedofft und eine neue Umspulhülse 9 auf dem Fadenfuhrerrohr 7 in Umspulstellung positioniert wurde, die Fadenlöseeinrichtung 14 mittels ihres Antriebes 23 wieder in das Zentrifugenspinnelement 3 eingefahren und leitet einen erneuten Umspulvorgang ein. The thread releasing device 14 is also used if a winding break occurred during the rewinding process. That is, if only a part of the package 15 could be rewound onto the winding tube 9. Even in such a case, after the partially wound spinning cop is doped and a new rewinding sleeve 9 has been positioned on the thread guide tube 7 in the rewinding position, the thread release device 14 is retracted into the centrifuge spinning element 3 by means of its drive 23 and initiates a new rewinding process.
