Description

Die Erfindung betrifft eine Antriebseinheit für den Antrieb eines Revolver-Spulkopfes zum Aufspulen von Vorgarn auf Spulhülsen.The invention relates to a drive unit for driving a turret winding head for winding roving on winding tubes.

Mit Vorspinnmaschinen werden sogenannte Vorgarne oder Lunten hergestellt, welche als Vorlage für die Verspinnung zu einem Fasergarn beispielsweise auf einer Ringspinnmaschine verwendet werden. Das zur Vorlage für Ringspinnmaschinen dienende Vorgarn wird üblicherweise aus einem Streckenband hergestellt, das auf einem Streckwerk der Vorspinnmaschine verzogen wird und anschliessend einen leichte Drehung erhält, damit das Vorgarn verzugsfrei auf eine Spule aufgewickelt werden kann. Die erteilte Drehung darf nur so hoch sein, dass der Zusammenhalt der Fasern für das Aufwickeln und wieder Abspulen sowie den Transport der Spulen fest genug ist. Andererseits muss diese so genannte Schutzdrehung im Hinblick auf den Verzug auf Ringspinnmaschinen so gering sein, dass im weiteren Verarbeitungsprozess keine Verzugsstörungen entstehen. Das Vorgarn muss trotz der eingebrachten Schutzdrehung verzugsfähig sein.With roving so-called rovings or lunts are produced, which are used as a template for the spinning to a fiber yarn, for example on a ring spinning machine. The roving used for the template for ring spinning machines is usually made from a conveyor belt, which is warped on a drafting of the roving and then receives a slight rotation, so that the roving can be wound on a bobbin without distortion. The given rotation may only be so high that the cohesion of the fibers for the winding and rewinding and the transport of the coils is strong enough. On the other hand, this so-called protective rotation with regard to the distortion on ring spinning machines must be so low that no distortion disturbances occur in the further processing process. The roving must be delayable despite the introduced protective rotation.

Das zur Herstellung des Vorgarns verwendete Streckenband besteht aus sogenannten Kurzstapelfasern. Bevorzugterweise werden dabei Fasern aus Baumwolle oder Mischungen aus Baumwollfasern und künstlich hergestellten Fasern benutzt. Bei der Verarbeitung von natürlichen Fasern wie Baumwolle in einem Spinnereiprozess werden Schmutz oder Kurzfasern sowie Teile von Fasern aus dem Streckenband herausgelöst und gelangen in die Umgebung. Derlei umherfliegende Bestandteile oder auch daraus entstehende Ablagerungen stellen eine Gefahr für die verwendete Maschinentechnik dar. Der Grad der Verschmutzung nimmt bei Änderungen der Laufbedingungen zu, insbesondere bei einer Steigerung der Geschwindigkeit der Luntenproduktion.The conveyor belt used for the production of the roving consists of so-called short staple fibers. Preferably, fibers of cotton or mixtures of cotton fibers and man-made fibers are used. When processing natural fibers such as cotton in a spinning process dirt or short fibers and parts of fibers are removed from the conveyor belt and get into the environment. Such flying components or resulting deposits pose a risk to the machine technology used. The degree of soiling increases with changes in running conditions, in particular with an increase in the speed of the lint production.

Heutige Vorspinnmaschinen zur Herstellung von Lunten leisten ein mehrfaches an Geschwindigkeit als frühere Maschinen. Die hohen Liefergeschwindigkeiten erfordern entsprechend an die neuen Gegebenheiten angepasste Spulmaschinen.Today's roving machines for the production of Lunten make a multiple of speed than earlier machines. The high delivery speeds require appropriately adapted to the new circumstances winder.

Aus der Chemiefaserherstellung sind Aufspulmaschinen bekannt, welche sich für kontinuierlich mit hoher Geschwindigkeit auflaufende Fäden eignen und bei einem Spulhülsenwechsel keine Änderung resp. Absenkung der Lieferleistung erfordern. Eine derartige Aufspulmaschine offenbart beispielsweise die EP 1 053 967 . Die Aufspulmaschine weist einen Revolver-Spulkopf auf, an welchem zwei Spulendorne gehalten sind. Ein erster Spulendorn ist in einer Aufwindeposition und ein zweiter Spulendorn befindet sich in einer Dofferposition. In der Dofferposition werden die vollen Spulen vom Spulendorn entnommen und durch leere Hülsen ersetzt. Sind die sich in der Aufwindeposition befindlichen Spulen voll, wird der Revolver um 180° gedreht und die Spulendorne tauschen die Position. Die auflaufenden Fäden werden ohne Unterbruch oder Verminderung der Lieferleistung durch die erfolgte Drehung des Revolvers von den vollen Spulen getrennt und von den leeren Hülsen übernommen. Die Spulendorne sind horizontal angeordnet. Die Fadenführung von welcher der Faden zur Changierung wechselt, ist in einem bestimmten Abstand von der Changierung selbst entfernt. Dadurch ergibt sich für den Faden vom Fadenführer zur äussersten Stellung der Changierung ein längerer Weg, als wenn die Changierung in der Mittelstellung ist. Aufgrund dessen ergibt sich mit jeder Bewegung der Changierung ein bestimmter Verzug. Bei den beschriebenen Aufspulmaschinen verarbeiteten Garnen handelt es sich um Endlosfäden aus einem Polymer. Es entstehen deshalb in der Regel kein Schmutz oder herumfliegender Staub sowie aus dem Faserverband herausgelöste Kurzfasern. Im Gegensatz dazu ist eine Verarbeitung von Baumwolle mit einem erheblichen Anfall von Schmutz, Staub und Kurzfasern oder Bruchstücken von Fasern verbunden. Dieser Umstand führt dazu, dass Baumwolle verarbeitende Maschinen mit Reinigungen und Absaugungen ausgerüstet werden.From the man-made fiber production winding machines are known, which are suitable for continuous running at high speed threads and at a Spulhülsenwechsel no change resp. Lower delivery performance. Such a winding machine discloses, for example, the EP 1 053 967 , The winding machine has a turret winding head, on which two bobbin spindles are held. A first bobbin is in a winding position and a second bobbin is in a doffing position. In the Dofferposition the full bobbins are removed from the mandrel and replaced by empty tubes. When the bobbins in the winding position are full, the turret is turned through 180 ° and the bobbin spindles swap positions. The running threads are separated without interruption or reduction of delivery performance by the rotation of the revolver from the full bobbins and taken over by the empty tubes. The spool pins are arranged horizontally. The thread guide from which the thread changes to traversing, is located at a certain distance from the traversing itself. This results in a longer path for the thread from the thread guide to the outermost position of the traversing, as if the traversing is in the middle position. Due to this, any movement of the traversing results in a certain delay. The yarns processed in the described winding machines are endless threads made of a polymer. Therefore, as a rule, no dirt or flying dust as well as short fibers extracted from the fiber structure arise. In contrast, cotton processing is associated with a significant amount of dirt, dust and short fibers or fragments of fibers. This circumstance leads to the fact that cotton processing machines are equipped with cleaning and suction.

Ein Revolver-Spulkopf gemäß dem Oberbegriff des Anspruchs 1 ist aus der JP 7 133505 A bekannt.A revolver winding head according to the preamble of claim 1 is known from JP 7 133505 A known.

Die Aufgabe der vorliegenden Erfindung ist es daher, eine Vorrichtung zum Aufspulen von Vorgarn zu schaffen, welche ein unterbruchfreies Aufspulen eines Vorgarns ermöglicht und die Vorrichtung von einer rohstoffbedingten Verschmutzung freizuhalten vermag, insbesondere sollen wartungsaufwändige Bauteile wie Antriebe und Lagerstellen von einer Verschmutzung durch herumfliegende oder sich absetzende Schmutzpartikel und Kurzfasern bewahrt werden.The object of the present invention is therefore to provide a device for winding roving, which enables a continuous roving of a roving and is able to keep the device from a raw material-related pollution, in particular should be maintenance-consuming components such as drives and bearings from contamination by flying around or Depositing dirt particles and short fibers are preserved.

Die Aufgabe wird gelöst durch einen Revolver-Spulkopf zum Aufspulen eines Vorgarns mit den Merkmalen nach dem unabhängigen Anspruch 1. Der Revolver-Spulkopf umfasst ein geschlossenes Gehäuse, wobei eine Revolvergrundplatte als ein Teil des Gehäuses ausgebildet ist. In der Revolvergrundplatte ausserhalb des Gehäuses sind eine erste Spindel und eine zweite Spindel angeordnet. Die erste Spindel ist mit einem ersten Antrieb und die zweite Spindel mit einem zweiten Antrieb versehen, wobei die Antriebe innerhalb des Gehäuse angeordnet sind. Der erste und der zweite Antrieb ist mit jeweils einem Lüfterrad ausgerüstet. Am ersten Antrieb und am zweiten Antrieb ist ansaugseitig des Lüfterrades jeweils ein Ansaugkanal vorgesehen, durch welchen ein Ansaugen von Luft durch das Lüfterrad von ausserhalb des Gehäuses vorgesehen ist.The object is achieved by a revolver winding head for winding a roving with the features of independent claim 1. The turret winding head comprises a closed housing, wherein a turret base plate is formed as a part of the housing. In the turret base plate outside the housing, a first spindle and a second spindle are arranged. The first spindle is provided with a first drive and the second spindle with a second drive, wherein the drives are arranged within the housing. The first and the second drive are each equipped with a fan. At the first drive and at the second drive, an intake passage is provided on the intake side of the fan wheel, through which an intake of air through the impeller from outside the housing is provided.

Der Revolver-Spulkopf nach der Erfindung ist in seiner Bauart ähnlich den bekannten Revolver-Spulköpfen aus der Chemiefaser-Technologie aufgebaut. Im Unterschied zu herkömmlichen Revolver-Spulköpfen ist die Revolvergrundplatte jedoch horizontal und die in der Revolvergrundplatte gelagerten Spindeln vertikal angeordnet. Dadurch ist es möglich nach dem Stand der Technik bekannte Flyerhülsen für die Aufspulung zu benutzen. Die hat den Vorteil, dass eine Kompatibilität zu den nachfolgenden Endspinnverfahren besteht und kein Umspulen oder gar ein Umrüsten der nachfolgenden Maschinen erfolgen muss. Flyerhülsen nach dem Stand der Technik werden beispielsweise durch die EP 0 927 696 offenbart.The revolver winding head according to the invention is constructed in its design similar to the known turret winding heads from the man-made fiber technology. However, unlike conventional turret winders, the turret base plate is horizontal and the spindles mounted in the turret base plate are arranged vertically. This makes it possible to use according to the prior art flyer sleeves for winding. This has the advantage that there is compatibility with the subsequent final spinning processes and no rewinding or even retooling of the downstream machines has to take place. Flyer sleeves according to the prior art, for example, by the EP 0 927 696 disclosed.

Um die Antriebseinheiten der Spindeln und der Revolvergrundplatte frei von Verschmutzungen zu halten, sind diese in einem Gehäuse unterhalb der Revolvergrundplatte untergebracht. Die Antriebseinheiten umfassen die Motoren sowie notwendige Getriebe und die Kraftübertragungselemente wie Riementriebe oder Kupplungen und Bremsen oder andersartige für den Antrieb der verschiedenen Elemente notwendige Ausrüstung. Die Revolvergrundplatte bildet dabei einen Teil des Gehäuses. Die Motoren für den Antrieb der Spindeln sind mit einem Lüfterrad ausgerüstet. Da während des Aufspulvorganges immer eine der beiden Spindeln und damit auch der zugehörige Antrieb in Betrieb ist, wird über das entsprechende Lüfterrad auch Luft zur Kühlung des Motors über dessen Kühlrippen geleitet. Diesen Umstand macht sich die Erfindung zunutze. Auf der Ansaugseite des Lüfterrades ist ein Ansaugkanal vorgesehen, welcher eine Öffnung im Gehäuse mit der Ansaugöffnung des Lüfterrades verbindet. Dadurch wir durch das Lüfterrad Luft von ausserhalb des Gehäuses angesaugt und in das Gehäuse geblasen. Jeder der beiden Spindelantriebe ist mit einem separaten Ansaugkanal für das jeweilige Lüfterrad versehen. Die beiden Ansaugkanäle verbinden auch zwei unabhängige Öffnungen mit dem jeweiligen Lüfterrad. Bevorzugterweise sind die Ansaugkanäle mit einem Filter ausgestattet. Dieser Filter verhindert, dass Staub und Schmutz durch ein Lüfterrad angesaugt und in das Gehäuse eingebracht wird. Angepasst an die Anforderungen an die Staubkonzentration innerhalb des Gehäuses können verschiedene Bauarten von Filtern eingesetzt werden. Denkbar sind einfache Maschengitter, Filter aus textilem Gewebe sowie andere aus dem Stand der Technik bekannte Filter.In order to keep the drive units of the spindles and the turret base plate free of contamination, these are housed in a housing below the turret base plate. The drive units include the motors and necessary gears and the power transmission elements such as belt drives or clutches and brakes or other equipment necessary for driving the various elements. The turret base plate forms a part of the housing. The motors for driving the spindles are equipped with a fan. Since during the winding process always one of the two spindles and thus also the associated drive is in operation, air is also routed to the cooling of the engine via the cooling fan via the corresponding fan. This circumstance makes use of the invention. On the suction side of the fan wheel, an intake passage is provided, which connects an opening in the housing with the suction opening of the fan wheel. As a result, we sucked air from outside the housing through the fan and blown it into the housing. Each of the two spindle drives is provided with a separate intake duct for the respective fan wheel. The two intake ports also connect two independent ports to the respective fan. Preferably, the intake ports are equipped with a filter. This filter prevents dust and dirt from being sucked in by a fan and inserted into the housing. Adapted to the dust concentration requirements within the housing, different types of filters can be used. Conceivable are simple mesh screens, filters made of textile fabric and other known from the prior art filter.

Das Gehäuse ist nicht luft- oder staubdicht ausgeführt. So ist auch im Ansaugkanal kein Verschlussorgan zu dessen Schliessung vorgesehen. Auch ist es nicht notwendig die drehbare Revolvergrundplatte gegen die Gehäusewandung abzudichten. Die durch das in Betrieb stehende Lüfterrad angesaugte Luft wird ins Innere des Gehäuses geblasen, was zur Erzeugung eines Überdrucks gegenüber der Umgebung führt. Erreicht der Überdruck einen bestimmten Wert, entweicht die Luft automatisch über die vorhandenen absichtlich geschaffenen Undichtigkeiten in die Umgebung. Der im Gehäuse herrschende Unterdruck entspricht dem Druckverlust aller vorhandenen Undichtigkeiten und regelt sich automatisch aufgrund der Grösse der Undichtigkeiten ein. Eine der Undichtigkeiten beispielsweise ist der Ansaugkanal des nicht in Betrieb stehenden Antriebs der sich in der Dofferposition befindlichen Spindel. Durch den im Inneren des Gehäuses vorherrschenden Überdruck wird ein Eindringen von Verschmutzungen vermieden und es ist auch in einer staubigen Umgebung eine hohe Betriebssicherheit gegeben.The housing is not made air or dustproof. Thus, no closure member is provided for the closure in the intake. Also, it is not necessary to seal the rotatable turret base plate against the housing wall. The air drawn in by the operating fan is blown into the interior of the housing, causing an overpressure to the environment. If the overpressure reaches a certain value, the air escapes automatically through the existing deliberately created leaks into the environment. The prevailing negative pressure in the housing corresponds to the pressure loss of all existing leaks and automatically adjusts itself due to the size of the leaks. One of the leaks, for example, is the intake passage of the inoperative drive of the spindle located in the doffer position. The prevailing in the interior of the housing overpressure ingress of contamination is avoided and it is given in a dusty environment high reliability.

Bevorzugterweise ist der Antrieb einer Spindel ein Elektromotor mit einem angebauten Lüfterrad. Denkbar sind auch hydraulische oder pneumatische Antriebe. Für die Kraftübertragung vom Elektromotor zur Spindel ist ein Riementrieb vorgesehen. Aufgrund der Anordnung und Drehzahlen ist zwischen dem Elektromotor und dem Riementrieb vorteilhafterweise ein Getriebe geschaltet. Der erste Antrieb der ersten Spindel und der zweite Antrieb der zweiten Spindel ist im Gehäuse mit den zugehörigen Ansaugkanälen ortsfest eingebaut. Da die Spindeln bei einer Drehung des Revolvers jeweils ihre Position gegenüber den Motoren wechseln ist ein Riementrieb welcher über Riemenräder welche auf einer Hohlwelle in der Revolverachse gelagert sind von Vorteil. In einer derartigen Anordnung wird durch eine spiegelbildliche Anordnung der Motoren durch die an der Achse der Revolvergrundplatte angreifenden Kräfte eine Stabilisierung der Revolvergrundplatte erreicht. Durch die Riemenspannkräfte des ersten Antriebs von der einen Seite der Revolvergrundplattenachse und der Riemenspannkräfte des zweiten Antriebs von der anderen Seite der Revolvergrundplattenachse wird die Revolvergrundplatte in einer definierten Lage gehalten. Die Revolvergrundplatte selbst kann durch einen Motor angetrieben werden, welcher über einen Riemen- oder Kettentrieb versehen ist. Es kann auch ein Direktantrieb über einen entsprechenden Zahnkranz vorgesehen werden.Preferably, the drive of a spindle is an electric motor with an attached fan. Also conceivable are hydraulic or pneumatic drives. For the power transmission from the electric motor to the spindle a belt drive is provided. Due to the arrangement and speeds, a transmission is advantageously connected between the electric motor and the belt drive. The first drive of the first spindle and the second drive of the second spindle is installed in the housing with the associated intake ports stationary. Since the spindles each change their position relative to the motors with a rotation of the revolver is a belt drive which on pulleys which are mounted on a hollow shaft in the turret axis advantageous. In such an arrangement a stabilization of the revolver base plate is achieved by a mirror image arrangement of the motors by acting on the axis of the revolver base plate forces. By the belt tightening forces of the first drive from one side of the turret base plate axis and the belt tensioning forces of the second drive from the other side of the turret base plate axis, the turret base plate is held in a defined position. The turret base itself can be driven by a motor which is provided with a belt or chain drive. It can also be provided a direct drive via a corresponding sprocket.

Beim Betrieb des Revolver-Spulkopfes wird die vom Lüfterrad des jeweils in Betrieb stehenden Antriebs angesaugte Luft über einen Filter durch den Ansaugkanal von ausserhalb dem Gehäuse an den Antrieb herangeführt. Durch das Ansaugen der Luft von ausserhalb des Gehäuses entsteht innerhalb des Gehäuses ein Überdruck, dessen Grösse durch im Gehäuse vorhandene Undichtigkeiten und den Ansaugkanal des nicht in Betrieb stehenden Antriebs bestimmt wird. Die durch den Ansaugkanal des nicht in Betrieb stehenden Antriebs nach aussen strömende Luft führt zudem zur Reinigung des im Ansaugkanal und des im Ansaugkanal eingebauten Filters. Die Höhe des Unterdrucks kann bestimmt werden durch die Anzahl und Grösse der Undichtigkeiten im Gehäuse. Bevorzugterweise ist der Unterdruck und die Bauart und Grösse der Im Ansaugkanal vorgesehenen Filter so gewählt, dass sich eine Selbstreinigung der Filter im Ansaugkanal ergibt.During operation of the turret winding head, the air sucked in by the fan wheel of the drive in operation is supplied to the drive via a filter through the suction channel from outside the housing. By sucking in the air from outside the housing, an overpressure arises within the housing, the size of which is determined by leaks present in the housing and the intake passage of the drive which is not in operation. The air flowing outwards through the intake duct of the drive which is not in operation also leads to the cleaning of the filter installed in the intake duct and in the intake duct. The amount of negative pressure can be determined by the number and size of the leaks in the housing. Preferably, the negative pressure and the type and size of the filter provided in the intake duct are selected such that self-cleaning of the filters in the intake duct results.

Die Erfindung wird nachfolgend anhand von Figuren näher erläutert.
Figur 1 zeigt in schematischer Darstellung einen Revolverspulkopf. In einem Gehäuse 20 ist eine Revolvergrundplatte 2 gehalten und drehbar gelagert. Die Revolvergrundplatte 2 ist horizontal angeordnet und hat eine vertikale Drehachse 3. Die Revolvergrundplatte 2 wird mit einem Antrieb um die Drehachse 3 in Schritten von 180° rotiert, entsprechend dem Pfeil 8. In der Revolvergrundplatte 2 sind eine erste Spindel 4 und eine zweite Spindel 6 gehalten und drehbar gelagert. Die erste Spindel 4 ist über ihre Drehachse 5 mit einem Antrieb verbunden. Die zweite Spindel 6 ist über ihre Drehachse 7 mit einem Antrieb verbunden. Die erste und die zweite Spindel 4, 6 werden unabhängig voneinander angetrieben. Vorteilhafterweise sind die Antriebe der ersten und zweiten Spindel 4, 6 mit einer Frequenzsteuerung ausgestattet.The invention will be explained in more detail with reference to figures.
FIG. 1 shows a schematic representation of a revolver winding head. In a housing 20, a revolver base plate 2 is held and rotatably supported. The revolver base plate 2 is arranged horizontally and has a vertical axis of rotation 3. The revolver base plate 2 is rotated by a drive about the rotation axis 3 in steps of 180 °, according to the arrow 8. In the revolver base plate 2, a first spindle 4 and a second spindle 6 are held and rotatably supported. The first spindle 4 is connected via its axis of rotation 5 with a drive. The second spindle 6 is connected via its axis of rotation 7 with a drive. The first and the second spindle 4, 6 are driven independently. Advantageously, the drives of the first and second spindle 4, 6 are equipped with a frequency control.

Die erste Spindel 4 befindet sich in der Darstellung der Figur 1 in der Spulposition. Auf die Spindel 4 ist eine leere Spulhülse 10 aufgesetzt. Auf die Spulhülse 10 wird ein Vorgarn 1 aufgespult. Das Vorgarn 1 wird über die Changiermittel 11 auf die Spulhülse 10 aufgespult. Die Changiermittel 11 sind mit dem Gehäuse 20 verbunden und werden von diesem gehalten. Die Changiermittel 11 umfassen ein bewegbares Element, welches sich entlang der Spulhülse 9 auf und ab bewegt, wodurch sich eine gleichmässige Umwindung mit Vorgarn der, sich um die Drehachse 5 drehenden, Spulhülse 10 ergibt.The first spindle 4 is in the representation of FIG. 1 in the winding position. On the spindle 4, an empty winding tube 10 is placed. On the winding tube 10, a roving 1 is wound up. The roving 1 is wound on the winding tube 10 via the traversing means 11. The traversing means 11 are connected to the housing 20 and are held by this. The traversing means 11 comprise a movable element which moves up and down along the winding tube 9, resulting in a uniform winding with roving of the, about the rotation axis 5 rotating, winding tube 10 results.

Die zweite Spindel 6 befindet sich in der Darstellung der Figur 1 in der Dofferposition. Die zweite Spindel 6 wurde bereits von der vollen Spulhülse befreit. Die Entnahme von vollen Spulhülsen und das Aufsetzen von leeren Spulhülsen 10 kann automatisch durch entsprechende Manipulatoren oder Roboter erfolgen. Die Spindel 6 ist in ihrem oberen Bereich mit einem Befestigungselement 9 versehen. Das Befestigungselement 9 dient zur Stabilisierung einer Spulhülse 10 auf der Spindel 6. Eine leere Spulhülse 10 wird von oben auf die Spindel 6 aufgesetzt und anschliessend durch das Befestigungselement drehfest 9 gehalten. Das Befestigungselement 9 kann beispielsweise eine pneumatische Spannvorrichtung sein, welche nach dem Aufsetzen der Spulhülse drucklos gemacht wird und dadurch eine radiale Ausdehnung erfährt, was dazu führt, dass eine Spulhülse auf der Spindel 6 festgeklemmt wird.The second spindle 6 is in the representation of FIG. 1 in the doffing position. The second spindle 6 has already been freed from the full winding tube. The removal of full bobbins and the placement of empty bobbins 10 can be done automatically by appropriate manipulators or robots. The spindle 6 is provided in its upper region with a fastening element 9. The fastening element 9 is used to stabilize a winding tube 10 on the spindle 6. An empty winding tube 10 is placed from above on the spindle 6 and then held by the fastener rotatably 9. The fastening element 9 may be, for example, a pneumatic tensioning device, which is depressurized after placement of the winding tube and thereby undergoes a radial expansion, which results in a winding tube being clamped on the spindle 6.

Wenn die Spulhülse 10 mit einer vollen Wicklung versehen ist, wird die Revolvergrundplatte 2 um dessen Achse 3 um eine halbe Umdrehung (180°) in Pfeilrichtung 8 gedreht. Dadurch tauschen die erste und die zweite Spindel 4, 6 die Positionen. Die Changiermittel 11 werden mit der Drehung der Revolvergrundplatte 2 nicht mitgeführt. Durch die Drehung der Revolvergrundplatte 2 wird die leere Spulhülse 10, welche sich auf der zweiten Spindel 6 befindet, in die Spulposition und damit in den Verlauf des Vorgarns 1 hinein gedreht. Das Vorgarn 1 wird dadurch von der leeren Spulhülse 10 übernommen und von der vollen Spulhülse getrennt. Für die Übernahme des Vorgarns 1 auf die leere Spulhülse ist diese an einer bestimmten Stelle mit einer Fangvorrichtung versehen. Durch die Changiermittel 11 wird das Vorgarn 1 an die Stelle dieser Fangvorrichtung geführt. Sobald das Vorgarn 1 von der leeren Spulhülse übernommen worden ist, beginnen die Changiermittel 11 mit der gleichmässigen Aufspulung des Vorgarns 1 auf die leere Spulhülse durch eine gesteuerte Auf- und Ab-Bewegung.When the winding tube 10 is provided with a full winding, the revolver base plate 2 is rotated about its axis 3 by half a turn (180 °) in the direction of arrow 8. As a result, the first and second spindles 4, 6 exchange positions. The traversing means 11 are not carried along with the rotation of the revolver base plate 2. By the rotation of the revolver base plate 2, the empty winding tube 10, which is is on the second spindle 6, rotated in the winding position and thus in the course of the roving 1 in. The roving 1 is thereby taken over by the empty winding tube 10 and separated from the full winding tube. For the acquisition of the roving 1 on the empty winding tube this is provided at a certain point with a safety device. By the traversing means 11, the roving 1 is guided to the point of this safety gear. Once the roving 1 has been taken over by the empty winding tube, the traversing means 11 begin with the uniform winding of the roving 1 on the empty winding tube by a controlled up and down movement.

In der Wandung des Gehäuses 20 sind Öffnungen für den Anschluss von Ansaugkanälen vorgesehen, welche mit jeweils einem Filter 21, 22 verschlossen werden.In the wall of the housing 20 openings for the connection of intake ports are provided, which are each closed with a filter 21, 22.

Figur 2 zeigt in schematischer Darstellung einen Teil-Querschnitt durch den Revolver-Spulkopf nach der Figur 1. Die Revolvergrundplatte 2 stellt einen Teil des Gehäuses 20 dar. Zwischen der Revolvergrundplatte 2 und dem Gehäuse 20 ist ein Spiel 31 vorhanden. Die Revolvergrundplatte 2 ist mit ihrer Drehachse 3 im Gehäuse 20 gelagert und durch einen Antrieb (nicht gezeigt) drehbar in Pfeilrichtung 8. In der Revolvergruridplatte 2 ist die erste Spindel 4 gehalten und gelagert. Im Gehäuse 20 ortsfest befestigt ist der Elektromotor 25 für den Antrieb der Spindel 4. Der Elektromotor 25 ist mit einem Lüfterrad 24 ausgerüstet. Die Motorwelle des Elektromotors 25 geht über in ein Getriebe 26, an welches ein Riementrieb 28 anschliesst. Über den Riementrieb 28 wird die Spindel 4 in Drehung versetzt. Der Riementrieb 28 ist zweistufig angelegt und führt über eine Hohlwelle 27, welche in der Drehachse 3 der Revolvergrundplatte 2 angeordnet ist. Durch diese Anordnung kann bei einem Spulwechsel von der ersten Spindel 4 auf die zweite Spindel die Revolvergrundplatte 2 um 180° gedreht werden, ohne dass der Antrieb der Spindel 4 in seiner Position verändert werden muss. FIG. 2 shows a schematic representation of a partial cross section through the turret winding head according to the FIG. 1 , The revolver base plate 2 constitutes a part of the housing 20. Between the revolver base plate 2 and the housing 20 there is a clearance 31. The revolver base plate 2 is mounted with its axis of rotation 3 in the housing 20 and by a drive (not shown) rotatable in the direction of arrow 8. In the Revolvergruridplatte 2, the first spindle 4 is held and stored. Fixed in the housing 20, the electric motor 25 for driving the spindle 4. The electric motor 25 is equipped with a fan 24. The motor shaft of the electric motor 25 merges into a gear 26, to which a belt drive 28 connects. About the belt drive 28, the spindle 4 is rotated. The belt drive 28 is applied in two stages and leads via a hollow shaft 27, which is arranged in the rotation axis 3 of the revolver base plate 2. By this arrangement, the revolver base plate 2 can be rotated by 180 ° in a Spulwechsel from the first spindle 4 to the second spindle, without the drive of the spindle 4 must be changed in position.

Auf der Ansaugseite des Lüfterrades 24 ist ein Ansaugkanal 23 angeschlossen. Durch den Ansaugkanal 23 wird eine Verbindung vom Lüfterrad 24 zu einer Öffnung im Gehäuse 20 geschaffen. In der Öffnung des Gehäuses 20 ist ein Filter 21 eingebaut. Beim Betrieb des Elektromotors 25 wird das Lüfterrad 24 ebenfalls angetrieben und saugt Luft von ausserhalb des Gehäuses 20 über den Filter 21 an, es ergibt sich ein Ansaugstrom 29. Der Elektromotor 25 ist in Betrieb, wenn die Spindel 4 in der Aufwindeposition ist. Vom Lüfterrad 24 wird der Ansaugstrom 29 über die Kühlrippen des Elektromotors 25 in das Innere des Gehäuses 20 geleitet und ergibt einen einströmenden Luftstrom 30. Über Undichtigkeiten im Gehäuse 20, welche absichtlich geschaffen wurden, entweicht die durch das Lüfterrad 24 in das Gehäuse 20 eingeblasene Luft wieder. Undichtigkeiten werden beispielsweise gebildet durch den Ansaugkanal des stillstehenden Antriebs der in der Dofferposition befindlichen Spindel oder dem Spiel 31 zwischen Gehäuse 20 und Revolvergrundplatte 2. Es können auch weitere Undichtigkeiten vorgesehen werden, beispielsweise an den Nahtstellen der Gehäusewandungen. Durch den einströmenden Luftstrom 30 entstehenden Überdruck im Gehäuse 20 wird sichergestellt, dass an den undichten Stellen des Gehäuses 20 immer eine Strömung vom Inneren des Gehäuses 20 nach aussen besteht. Dies verhindert ein Eindringen von Staub und Schmutz in das Innere des Gehäuses 20 und erhöht die Betriebssicherheit der gesamten Antriebseinheit.On the suction side of the fan 24, an intake passage 23 is connected. Through the intake passage 23, a connection is created by the fan 24 to an opening in the housing 20. In the opening of the housing 20, a filter 21 is installed. During operation of the electric motor 25, the fan 24 is also driven and sucks air from outside the housing 20 via the filter 21, there is an intake flow 29. The electric motor 25 is in operation when the spindle 4 is in the winding position. From the fan 24, the suction flow 29 is passed through the cooling fins of the electric motor 25 into the interior of the housing 20 and results in an incoming air flow 30. About leaks in the housing 20, which were deliberately created escapes blown by the fan 24 in the housing 20 air again. Leaks are formed for example by the suction of the stationary drive located in the doffer position spindle or the game 31 between the housing 20 and revolver base plate 2. It can also be provided further leaks, for example, at the seams of the housing walls. By the inflowing air flow 30 resulting pressure in the housing 20 ensures that there is always a flow from the interior of the housing 20 to the outside at the leaks of the housing 20. This prevents ingress of dust and dirt into the interior of the housing 20 and increases the reliability of the entire drive unit.
