Description

Die vorliegende Erfindung betrifft eine Spinnereivorbereitungsmaschine, mit wenigstens einem Verfestigungsmittel zum Herstellen eines eine Schutzdrehung aufweisenden Vorgarns aus einem dem Verfestigungsmittel zugeführten Faserverband, mit einem Streckwerk zum Verstrecken des Faserverbands vor dem Eintritt desselben in das Verfestigungsmittel, wobei das Streckwerk dem Verfestigungsmittel in einer Transportrichtung des Streckwerks vorgeordnet ist, wobei die Spinnereivorbereitungsmaschine eine Spulvorrichtung zum Aufspulen des Vorgarns auf eine Hülse aufweist, und wobei die Spinnereivorbereitungsmaschine eine Hülsentransporteinrichtung zum Bereitstellen von leeren Hülsen und/oder zum Abführen von mit Hilfe der Spulvorrichtung mit Vorgarn bespulten Hülsen aufweist. Gattungsgemäße Spinnereivorbereitungsmaschinen sind im Stand der Technik bekannt und dienen der Herstellung von so genanntem Vorgarn. Vorgarn wird aus meist mit Hilfe von Strecken vorbehandelten (z. B. dublierten) Faserbändern hergestellt und dient als Vorlage für den anschließenden Spinnprozess, bei dem die einzelnen Fasern des Vorgarns, beispielsweise mit Hilfe einer Ringspinnmaschine, zu einem Garn versponnen werden. Um dem Vorgarn die für die Weiterverarbeitung nötige Festigkeit zu verleihen, hat es sich bewährt, den vorgelegten Faserverband während der Herstellung des Vorgarns mit Hilfe eines Streckwerks, das meist Teil der entsprechenden Spinnereivorbereitungsmaschine ist, zu verstrecken und anschließend mit einer Schutzdrehung zu versehen. Die genannte Festigkeit ist wichtig, um ein Reißen des Vorgarns beim Aufwickeln auf eine Hülse bzw. während der Zufuhr zur nachgeschalteten Spinnmaschine zu verhindern. Die erteilte Schutzdrehung muss hierbei einerseits so stark sein, dass ein Zusammenhalt der einzelnen Fasern während der einzelnen Auf- bzw. Abspulvorgänge sowie entsprechender Transportvorgänge zwischen den jeweiligen Maschinentypen gewährleistet ist. Andererseits muss auch trotz der Schutzdrehung sichergestellt werden, dass das Vorgarn in einer Spinnmaschine weiterverarbeitet werden kann - das Vorgarn muss also weiterhin verzugsfähig sein.The present invention relates to a spinning preparation machine comprising at least one solidifying agent for producing a protective roving from a fiber structure fed to the solidifying agent, having a drafting device for stretching the fiber composite prior to entering the solidifying agent, the drafting means being the consolidating means in a conveying direction of the drafting system wherein the spinning preparation machine comprises a winding device for winding the roving onto a sleeve, and wherein the spinning preparation machine comprises a sleeve transporting device for providing empty tubes and / or for discharging sleeves which have been coiled with roving by means of the winding device. Generic spinning preparation machines are known in the art and serve for the production of so-called roving. Roving is produced from slivers pretreated (eg doubled) with the aid of stretching and serves as a template for the subsequent spinning process in which the individual fibers of the roving are spun into a yarn, for example by means of a ring spinning machine. In order to give the roving the necessary strength for further processing, it has proven useful to stretch the submitted fiber structure during the production of the roving by means of a drafting system, which is usually part of the corresponding spinning preparation machine, and then provided with a protective rotation. The said strength is important to prevent ripping of the roving when winding on a sleeve or during the supply to the downstream spinning machine. On the one hand, the given protective rotation must on the one hand be so strong that a cohesion of the individual fibers during the individual winding or unwinding operations as well as corresponding transport processes between the respective machine types is guaranteed. On the other hand, it must be ensured despite the protective rotation that the roving can be further processed in a spinning machine - the roving must therefore continue to be delayable.

Um ein entsprechendes Vorgarn herzustellen, kamen in der Vergangenheit meist so genannte Flyer zum Einsatz, deren Liefergeschwindigkeit jedoch aufgrund auftretender Fliehkräfte beschränkt ist. Es gab daher bereits vielfältige Vorschläge, den Flyer zu umgehen oder durch einen alternativen Maschinentypus zu ersetzen.To produce a corresponding roving, so-called flyers were used in the past, but their delivery speed is limited due to centrifugal forces occurring. Therefore, there were already many suggestions to bypass the flyer or replace it with an alternative machine type.

Unter anderem wurde in diesem Zusammenhang auch bereits vorgeschlagen, Vorgarn mit Hilfe von Luftspinnmaschinen herzustellen, bei dem die Schutzdrehung mit Hilfe von Wirbelluftströmungen erzeugt wird. Das Grundprinzip besteht dabei darin, einen Faserverband durch ein als Luftspinndüse ausgebildetes Verfestigungsmittel zu führen, in dem ein Luftwirbel erzeugt wird. Dieser bewirkt schließlich, dass ein Teil der äußeren Fasern des zugeführten Faserverbands als sogenannte Umwindefasern um den zentral verlaufenden Faserstrang geschlungen wird, der wiederum aus im Wesentlichen parallel zueinander verlaufenden Kernfasern besteht.Among other things, it has already been proposed in this context to produce roving by means of air spinning machines, in which the protective rotation is generated by means of vortex air flows. The basic principle is to guide a fiber structure through a solidifying agent designed as an air-jet nozzle, in which an air vortex is generated. This finally causes a part of the outer fibers of the fiber composite supplied is wrapped as a so-called Umwindefasern to the centrally extending fiber strand, which in turn consists of substantially mutually parallel core fibers.

Ein weiteres Verfahren zur Vorgarnherstellung ist in der DE 24 47 715 A1 offenbart. Die dort beschriebene Verfestigung des unverfestigten Faserverbands erfolgt mit Hilfe eines Verfestigungsmittels, das keine Drehung, sondern ein spiralförmiges Umschlingen eines Faserbandes durch ein oder mehrere Filamentgarne, bevorzugt monofile Filamentgarne, bewirkt, die den Faserverband zusammenhalten und ihm seine Festigkeit verleihen. Die Spiralen der einzelnen Filamentgarne können hierbei gleichsinnig oder gegensinnig angeordnet sein. Bevorzugt werden zwei Filamentgarne, die in gegensinniger Drehung bzw. sich überkreuzend angeordnet sind. Das auf diese Weise erzeugte Vorgarn setzt sich somit im Wesentlichen aus einem Faserband parallelisierter Stapelfasern und einem oder mehreren das Faserband spiralförmig umschlingenden feintitrigen Filamentgarnen zusammen.Another method for roving is in the DE 24 47 715 A1 disclosed. The solidification of the unconsolidated fiber structure described therein is effected by means of a solidifying agent, which causes no rotation, but a spiral wrapping of a sliver by one or more filament yarns, preferably monofilament filament yarns, which hold together the fiber structure and give it its strength. The spirals of the individual filament yarns can be arranged in the same direction or in opposite directions. Preference is given to two filament yarns, which are arranged in opposite directions or cross over. The roving produced in this way is thus essentially composed of a sliver of parallelized staple fibers and one or more fine-denier filament yarns spirally wound around the sliver.

Zur Umwindung des unverfestigten Faserverbands mit dem Filamentgarn oder den Filamentgarnen gibt es verschiedene Möglichkeiten. Zum Beispiel kann das Filamentgarn auf kleine Spulen geringen Durchmessers aufgebracht werden. Das Filamentgarn wird anschließend von der feststehenden Spule abgezogen und zusammen mit dem Faserverband durch die Spulenachse hindurchgezogen, wobei der Faserverband vom Filamentgarn umwunden wird und die Zahl der von der Spule abgezogenen Wicklungen der Anzahl der auf den Faserverband aufgebrachten Umwindungen entspricht. Grundsätzlich ist es auch möglich, das Verfestigungsmittel derart auszubilden, dass nur der unverfestigte Faserverband durch die Spulenachse geführt wird, um hierdurch den Umwindevorgang hinter die Filamentgarnspule zu verlegen. Der Umwindepunkt sollte dabei durch einen geeigneten Fadenführer festgelegt werden.To wrap the unconsolidated fiber composite with the filament yarn or the filament yarns, there are various possibilities. For example, the filament yarn be applied to small coils of small diameter. The filament yarn is then pulled off the stationary bobbin and pulled through the bobbin axis along with the fiber strand, the filament yarn being wound around the fiber web and the number of turns drawn from the bobbin corresponding to the number of turns applied to the fiber web. In principle, it is also possible to form the solidification agent in such a way that only the unconsolidated fiber structure is guided through the coil axis, in order thereby to lay the wrapping process behind the filament yarn package. The binding point should be determined by a suitable thread guide.

Ein weiteres Verfahren zur Herstellung von Vorgarn beschreibt die WO 2009/086646 A1 , wobei das Verfahren die folgenden Schritte umfasst: 1) Bereitstellen eines Faserverbands in Form zweier, vorzugsweise ungedrehter, Faserbänder, 2) Erteilung von S- und Z-Drehungen über sich abwechselnde Bereiche der beiden Faserbänder, wobei Bereiche von S- und Z- Drehungen am jeweiligen Faserband durch Bereiche ohne Drehung getrennt sind, 3) Zusammenführen der beiden mit S- und Z- Drehungen versehenen Faserbänder zu einem Vorgarn, wobei sich die beiden Faserbänder aufgrund ihrer Rückdrehtendenz selbsttätig zusammendrehen.Another method for producing roving describes the WO 2009/086646 A1 the method comprising the steps of: 1) providing a fiber strand in the form of two, preferably untwisted, fiber ribbons, 2) imparting S and Z turns over alternating regions of the two fiber ribbons, with regions of S and Z turns 3) merging the two provided with S and Z turns fiber slivers into a roving, wherein the two slivers automatically spin together due to their tendency to reverse.

Die S- und Z-Drehungen können z. B. mittels zweier Elemente des zum Einsatz kommenden Verfestigungsmittels erzeugt werden, die das jeweilige Faserband klemmend halten, wobei wenigstens ein Element, vorzugsweise beide Elemente, dem Faserband durch eine Relativbewegung auf seiner Oberfläche quer zur Faserbandlängsrichtung zu beiden Seiten abwechselnd einander entgegen gesetzte Drehungen erteilen. Gleichzeitig wird das jeweilige Faserband in Faserbandrichtung bewegt. Die S- und Z-Drehungen können jedoch auch mittels eines aerodynamischen, insbesondere pneumatischen, Verfahrens erzeugt werden.The S and Z rotations can z. B. by means of two elements of the used solidifying agent, which hold the respective sliver clamping, at least one element, preferably both elements, the sliver by a relative movement on its surface transverse to the sliver longitudinal direction on both sides alternately impart opposing rotations. At the same time, the respective sliver is moved in sliver direction. However, the S and Z rotations can also be generated by means of an aerodynamic, in particular pneumatic, process.

Die sich abwechselnden S- und Z-Drehungen werden zudem durch Wechselbereiche ohne Drehung unterbrochen. Die beiden auf gleiche Weise mit S- und Z-Drehungen versehenen Faserbänder werden schließlich im so genannten Vereinigungspunkt zusammengeführt. Hier beginnen sich die Faserbänder selbsttätig zusammenzudrehen, d. h. sie umwinden sich gegenseitig. Dieses so genannte Fachen erhält die S- und Z-Drehungen in den einzelnen Faserbändern aufrecht, so dass ein sich selbst stabilisierendes Zweikomponenten-Vorgarn entsteht. Grundsätzlich ist hierbei jedoch zu beachten, dass die Bereiche ohne Drehung im ersten Faserband zu den Bereichen ohne Drehung im zweiten Faserband in Längsrichtung versetzt angeordnet sein sollten, so dass nie zwei Bereiche ohne Drehung des ersten und zweiten Faserbands im resultierenden Vorgarn nebeneinander liegen, da die Festigkeit des Vorgarns wesentlich von der Phasenlage der Bereiche ohne Drehung der beiden Faserbänder abhängt. Die Vorgarne werden deshalb, wie oben beschrieben, mit Hilfe des Verfestigungsmittels immer so zusammengeführt, dass ihre Bereiche ohne Drehung außer Phase liegen. Das auf diese Weise hergestellte Vorgarn weist schließlich gegenüber einem nicht gedrehten Faserverbund eine höhere Festigkeit auf, die letztendlich ausreicht, um das Vorgarn ohne Fehlverzüge auf eine Spule aufzuwickeln und von dieser wieder abzuwickeln. Generell besteht bei entsprechenden Spinnereivorbereitungsmaschinen stets das Bedürfnis, den benötigten Platzbedarf möglichst gering zu halten, wobei die Spinnereivorbereitungsmaschinen dennoch gut zugänglich sein sollten, um insbesondere Instandsetzungs- und Einstellungsarbeiten bzw. notwendige Fehlerbeseitigungsmaßnahmen nach einem ungewollten Stopp der Vorgarnherstellung durchführen zu können.The alternating S and Z turns are also interrupted by changing areas without rotation. The two slivers provided in the same way with S and Z turns are finally brought together in the so-called merging point. Here, the slivers begin to spin automatically, d. H. they wind each other over. This so-called Fachen maintains the S and Z turns in the individual slivers, so that a self-stabilizing two-component roving arises. In principle, however, it should be noted here that the regions without rotation in the first sliver should be arranged offset to the regions without rotation in the second sliver in the longitudinal direction, so that never two areas without rotation of the first and second sliver in the resulting roving adjacent to each other, as the Strength of the roving significantly depends on the phase position of the areas without rotation of the two slivers. The rovings are therefore, as described above, always brought together with the aid of the solidifying agent so that their areas are out of phase without rotation. The roving produced in this way finally has a higher strength compared to a non-twisted fiber composite, which is ultimately sufficient to wind the roving without Fehlverzüge on a spool and unwind from this again. In general, there is always the need to keep the required space as low as possible with appropriate spinning preparation machines, the spinning preparation machines should still be easily accessible to perform particular repair and adjustment work or necessary troubleshooting after an unwanted stop the Vorgarnherstellung can.

Aufgabe der vorliegenden Erfindung ist es daher, eine Spinnereivorbereitungsmaschine vorzuschlagen, die sich diesbezüglich in positiver Weise vom bekannten Stand der Technik unterscheidet.Object of the present invention is therefore to propose a spinning preparation machine, which differs in this regard in a positive manner from the prior art.

Die Aufgabe wird gelöst durch eine Spinnereivorbereitungsmaschine mit den Merkmalen des unabhängigen Patentanspruchs.The object is achieved by a spinning preparation machine with the features of the independent claim.

Erfindungsgemäß zeichnet sich die Spinnereivorbereitungsmaschine, deren Verfestigungsmittel vorzugsweise als Luftspinndüse ausgebildet ist und nach dem oben genannten Luftspinnverfahren arbeitet, dadurch aus, dass die Spinnereivorbereitungsmaschine eine dem Streckwerk in der genannten Transportrichtung vorgeordnete Führung zum Führen des Faserverbands zwischen einem das Faserverband bereitstellenden Behälter und dem Streckwerk aufweist, dass die Führung einen dem Streckwerk abgewandten Zuführabschnitt für den im Betrieb der Spinnereivorbereitungsmaschine aus dem Behälter stammenden Faserverband und einen dem Streckwerk zugewandten Abgabeabschnitt für den Faserverband aufweist, dass die Spinnereivorbereitungsmaschine eine Hülsentransfervorrichtung umfasst, die der Übergabe von Hülsen von der Hülsentransporteinrichtung an die Spulvorrichtung und/oder umgekehrt dient, dass die Spulvorrichtung und/oder die Hülsentransfervorrichtung zumindest teilweise unterhalb der Führung, unterhalb des Streckwerks und/oder unterhalb des Verfestigungsmittels angeordnet sind, und dass die Hülsentransporteinrichtung zumindest eine Transportbahn (z. B. in Form eines Transportbands) für den Transport von leeren und/oder mit Vorgarn bespulten Hülsen umfasst, wobei die Transportbahn(en) in einer Draufsicht der Spinnereivorbereitungsmaschine zumindest teilweise zwischen dem Zuführabschnitt der Führung für den Faserverband und dem Streckwerk angeordnet sind.According to the invention, the spinning preparation machine, whose solidifying agent is preferably designed as an air spinning nozzle and operates according to the above-mentioned air spinning method, characterized in that the spinning preparation machine has a the drafting in the transport direction upstream guide for guiding the fiber composite between the fiber dressing providing container and the drafting system in that the guide has a feed section facing away from the drafting device for the fiber structure originating from the container during operation of the spinning preparation machine and a drafting section for the fiber strand facing the drafting device, that the spinning preparation machine comprises a tube transfer device which permits the transfer of sleeves from the tube transporting device to the winding device and / or vice versa serves that the winding device and / or the sleeve transfer device at least partially below the guide , are arranged below the drafting system and / or below the solidifying agent, and that the sleeve transport device comprises at least one transport path (eg in the form of a conveyor belt) for the transport of empty and / or roving-wound sleeves, wherein the transport path (s) in a plan view of the spinning preparation machine at least partially are arranged between the feed section of the guide for the fiber structure and the drafting system.

Die Transportbahn(en) der beispielsweise auf einem Hallenboden des die Spinnereivorbereitungsmaschine aufnehmenden Halle fixierten Hülsentransporteinrichtung können beispielsweise mehrere Spulenhalter umfassen, die der Aufnahme jeweils einer leeren oder mit Hilfe der Spinnereivorbereitungsmaschine bespulten Hülsen dienen. Die Hülsenhalter sind beispielsweise durch Bewegung der Transportbahn(en) zwischen der Spinnereivorbereitungsmaschine und einem oder mehreren Sammelplätzen für die leeren bzw. bespulten Hülsen bewegbar, so dass die Spinnereivorbereitungsmaschine stets mit leeren Hülsen versorgt werden kann und die bespulten Hülsen von der Spinnereivorbereitungsmaschine abtransportiert werden können.The transport path (s) of the tube transporting device, which is fixed, for example, on an indoor floor of the hall receiving the spinning preparation machine, may, for example, comprise a plurality of bobbin holders which serve to receive empty pods or pods which are spooled with the aid of the spinning preparation machine. The sleeve holders are movable, for example, by movement of the transport path (s) between the spinning preparation machine and one or more collection stations for the empty or insufflated sleeves, so that the spinning preparation machine can always be supplied with empty tubes and the spooled tubes can be transported away from the spinning preparation machine.

Die genannten Hülsen werden in der Draufsicht der Spinnereivorbereitungsmaschine mit Hilfe der Transportbahn(en) zwischen dem Zuführabschnitt und dem Streckwerk hindurchgeführt, so dass der zwischen Zuführabschnitt und Streckwerk vorhandene Platz in vorteilhafter Weise für die teilweise Unterbringung der Transportbahn(en) genutzt wird. Die Führung für den Faserverband umfasst vorzugsweise eine Schiene, auf der der Faserverband aufliegt und damit eine Abstützung in vertikaler Richtung erhält. Beispielsweise wäre es denkbar, die Schiene durch ein, beispielsweise aus Metall oder Kunststoff bestehendes, längliches Profil zu bilden, das sich in horizontaler oder zur Horizontalen leicht geneigten Richtung zwischen dem Zuführabschnitt und dem Abgabeabschnitt der Führung erstreckt. Der Zuführ- und Abgabeabschnitt bilden vorzugsweise jeweils einen Endabschnitt der Führung, wobei der Zuführabschnitt im Bereich des Behälters (vorzugsweise oberhalb desselben) und der Abgabeabschnitt in der Nähe des Streckwerks angeordnet sein sollten. Insbesondere sollte sich der Abgabeabschnitt in unmittelbarer Nähe einer Eingangswalze des Streckwerks befinden, um einen möglichst nahtlosen Übergang zwischen Führung und Streckwerk zu ermöglichen. Generell ist es zudem von Vorteil, wenn der Zuführabschnitt höher platziert ist als der Abgabeabschnitt, so dass die Führung eine Rutsche für den Faserverband bildet. Insbesondere ist es von Vorteil, wenn sich die Führung senkrecht zu der oder den Transportbahn(en) erstreckt.The said sleeves are guided in the plan view of the spinning preparation machine by means of the transport path (s) between the feed section and the drafting system, so that the existing between feed section and drafting system is used advantageously for the partial housing of the transport path (s). The guide for the fiber structure preferably comprises a rail on which rests the fiber structure and thus receives a support in the vertical direction. For example, it would be conceivable to form the rail by an elongated profile, for example of metal or plastic, which extends in a horizontal or slightly inclined direction between the feed section and the delivery section of the guide. The feed and discharge sections preferably each form an end section of the guide, wherein the feed section should be arranged in the region of the container (preferably above it) and the discharge section in the vicinity of the drafting device. In particular, the discharge section should be located in the immediate vicinity of an input roller of the drafting system in order to allow the most seamless possible transition between the guide and the drafting system. In general, it is also advantageous if the feed section is placed higher than the delivery section, so that the guide forms a chute for the fiber structure. In particular, it is advantageous if the guide extends perpendicular to the or the transport path (s).

An dieser Stelle sei generell darauf hingewiesen, dass das genannte Verfestigungsmittel unterschiedlich ausgebildet sein kann. Beispielsweise wäre es denkbar, dass das Verfestigungsmittel geeignet ist, das Vorgarn auf die in den oben genannten Druckschriften WO 2009/086646 A1 und DE 24 47 715 A1 beschriebene Weise herzustellen. Bevorzugt ist die Spinnereivorbereitungsmaschine jedoch als Luftspinnmaschine und das Verfestigungsmittel als Luftspinndüse ausgebildet, durch die die Schutzdrehung der Vorgarns, wie oben beschrieben, mit Hilfe von Wirbelluftströmungen erzeugt wird (ein Ausschnitt einer entsprechenden, als Luftspinnmaschine ausgebildeten, Spinnereivorbereitungsmaschine ist beispielhaft in der Figurenbeschreibung beschrieben). Schließlich sei darauf hingewiesen, dass die erfindungsgemäße Spinnereivorbereitungsmaschine auch mehrere Einheiten, aufweisend jeweils ein Streckwerk, eine Führung, ein Verfestigungsmittel (beispielsweise in Form der genannten Luftspinndüse) und eine Spulvorrichtung, umfassen kann, wobei die Transportbahnen in diesem Fall zwischen den in einer Reihe angeordneten Streckwerken und den ebenfalls in einer Reihe angeordneten Zuführabschnitten der, vorzugsweise parallel zueinander verlaufenden, Führungen verlaufen sollten. Die Hülsentransfervorrichtung dient der Übergabe von Hülsen von der Hülsentransporteinrichtung an die Spulvorrichtung und/oder umgekehrt. Die Hülsentransfervorrichtung kann beispielsweise einen Hülsengreifer umfassen, der mit einer Steuerung der Spinnereivorbereitungsmaschine in Verbindung steht und der ausgebildet ist, eine bespulte Hülse von der Spulvorrichtung auf eine Transportbahn und eine leere Hülse von einer Transportbahn in oder auf die Spulvorrichtung zu bewegen, vorzugsweise zu heben.It should be noted at this point in general that the said solidifying agent can be designed differently. For example, it would be conceivable that the solidifying agent is suitable, the roving on in the above-mentioned publications WO 2009/086646 A1 and DE 24 47 715 A1 to produce described manner. Preferably, however, the spinning preparation machine is formed as an air spinning machine and the solidifying agent as an air spinning nozzle, by the protective rotation of the roving, as described above, is generated by means of vortex air flows (a section of a corresponding, designed as an air spinning machine, spinning preparation machine is described by way of example in the figure description). Finally, it should be noted that the spinning preparation machine according to the invention may also comprise a plurality of units, each comprising a drafting device, a guide, a solidifying agent (for example in the form of said air spinneret) and a winding device, the transport paths in this case being arranged between them in a row Draw frames and also arranged in a row Zuführabschnitten the, preferably parallel to each other, guides should run. The sleeve transfer device is used to transfer sleeves from the sleeve transport device to the winding device and / or vice versa. The sleeve transfer device may, for example, comprise a tube gripper communicating with a control of the spinning preparation machine and arranged to move, preferably lift, a spooled tube from the spooling device to a transport path and an empty tube from a transport path into or onto the spooling device.

Des Weiteren ist es vorteilhaft, wenn die Transportbahn(en) in einer Draufsicht der Spinnereivorbereitungsmaschine zumindest teilweise zwischen dem Zuführabschnitt und dem Abgabeabschnitt der Führung verlaufen. Der Faserverband wird hierbei beim Passieren der Transportbahn(en) zumindest in vertikaler Richtung durch die Führung gestützt, so dass eine Kollision zwischen dem Faserverband und den vorzugsweise unterhalb der Führung verlaufenden Transportbahn(en) bzw. den sich darauf befindlichen Hülsen verhindert wird. Insbesondere ist es von Vorteil, wenn die Transportbahn(en) in der genannten Draufsicht zwischen dem Zuführabschnitt der Führung und der Spulvorrichtung und/oder zwischen dem Zuführabschnitt der Führung und der Hülsentransfervorrichtung verläuft bzw. verlaufen. Der Zuführabschnitt liegt in diesem Fall in der genannten Draufsicht auf der einen Seite der bzw. den vorzugsweise senkrecht zu der Führung verlaufenden Transportbahn(en), während sich die Spulvorrichtung und/oder die Hülsentransfervorrichtung auf der anderen Seite der Transportbahn(en) befindet.Furthermore, it is advantageous if the transport path (s) extend at least partially between the feed section and the delivery section of the guide in a plan view of the spinning preparation machine. The fiber structure is thereby supported when passing through the transport path (s) at least in the vertical direction by the guide, so that a collision between the fiber structure and the preferably below the guide running transport path (s) or the sleeves located thereon is prevented. In particular, it is advantageous if the transport path (s) run or extend in said plan view between the feed section of the guide and the winding device and / or between the feed section of the guide and the tube transfer device. The feed section in this case lies in the above-mentioned plan view on one side of the transport path (s), preferably perpendicular to the guide, while the winding device and / or the tube transfer device is located on the other side of the transport path (s).

Ebenso ist es vorteilhaft, wenn die Führung die in einer Draufsicht der Spinnereivorbereitungsmaschine unterhalb der Führung angeordnete(n) Transportbahn(en), vorzugsweise den gesamten in der genannten Draufsicht unterhalb der Führung angeordneten Bereich der Hülsentransporteinrichtung, vollständig überspannt. Die Führung ist in diesem Fall als Brückenelement ausgebildet, so dass der Faserverband, unterstützt durch die Führung, oberhalb der Transportbahn(en) sowie der darauf geführten Hülsen geführt wird, so dass der sich in diesem Bereich eigentlich befindliche Freiraum für den Transport des Faserverbands genutzt werden kann. Die Führung kann im Übrigen ein oder mehrere Gestelle aufweisen, über die sie gegenüber einem Hallenboden oder einem Trägerabschnitt der Spinnereivorbereitungsmaschine abgestützt ist, wobei sich das bzw. die Gestelle in der Draufsicht der Spinnereivorbereitungsmaschine vorzugsweise seitlich der Transportbahn(en) befindet bzw. befinden.Likewise, it is advantageous if the guide completely spans the transport path (s) arranged below the guide in a plan view of the spinning preparation machine, preferably completely covering the entire region of the tube transport device arranged below the guide in the above-mentioned plan view. The guide is designed in this case as a bridge element, so that the fiber strand, supported by the guide, above the transport path (s) and the guided thereon sleeves is guided, so that the actually located in this area free space used for the transport of fiber composite can be. Incidentally, the guide may have one or more racks, by which it is supported relative to a hall floor or a carrier section of the spinning preparation machine, wherein the rack (s) is or are located laterally of the conveyor track (s) in the plan view of the spinning preparation machine.

Vorteilhaft ist es also, wenn der Zuführabschnitt, der Abgabeabschnitt und/oder ein dazwischen liegender Führungsabschnitt der Führung in einer Seitenansicht der Spinnereivorbereitungsmaschine oberhalb zumindest eines Teils der in einer Draufsicht zwischen dem Zuführabschnitt der Führung und dem Streckwerk verlaufen Transportbahn(en) angeordnet sind, wobei der vertikale Abstand zwischen der bzw. den Führungsbahn(en) und einem oder mehreren der genannten Abschnitte der Führung vorzugsweise mehr als 30 cm, bevorzugt mehr als 40 cm, besonders bevorzugt mehr als 50 cm, beträgt, um eine Kollision der Führung mit den unterhalb derselben transportierten Hülsen ausschließen zu können. Vorzugsweise ist schließlich auch der Zuführabschnitt, der Abgabeabschnitt und/oder der dazwischen liegende Führungsabschnitt der Führung in der genannten Seitenansicht der Spinnereivorbereitungsmaschine oberhalb zumindest eines Teils des Streckwerks und/oder des Verfestigungsmittels und/oder der Hülsentransfervorrichtung angeordnet.It is thus advantageous if the feed section, the discharge section and / or an intermediate guide section of the guide in a side view of the spinning preparation machine above at least a portion of the transport path (s) running in a plan view between the feed section of the guide and the drafting system are arranged, wherein the vertical distance between the guide track (s) and one or more of said sections of the guide is preferably more than 30 cm, preferably more than 40 cm, more preferably more than 50 cm, to a collision of To exclude leadership with the transported below the same sleeves. Finally, the feed section, the discharge section and / or the intermediate guide section of the guide are also arranged in the abovementioned side view of the spinning preparation machine above at least part of the drafting arrangement and / or the solidifying means and / or the tube transfer device.

Ebenso bringt es Vorteile mit sich, wenn die Spulvorrichtung und/oder die Hülsentransfervorrichtung in einer Draufsicht und/oder einer Seitenansicht der Spinnereivorbereitungsmaschine zumindest teilweise zwischen dem Zuführabschnitt der Führung und dem Verfestigungsmittel angeordnet sind. Das Verfestigungsmittel kann hierbei im Bereich eines vorderen stirnseitigen Endbereichs der Spinnereivorbereitungsmaschine angeordnet sein, während sich der Zuführabschnitt im Bereich eines zweiten, hinteren stirnseitigen Endabschnitts befinden kann, wobei die genannten Endabschnitte auf gegenüberliegenden Seiten der Transportbahn(en) platziert sein sollten. Denkbar ist es schließlich auch, dass die Spulvorrichtung und/oder die Hülsentransfervorrichtung in der genannten Draufsicht und/oder Seitenansicht zumindest teilweise zwischen dem Zuführabschnitt der Führung und dem Streckwerk angeordnet sind. Die Ausnutzung des verfügbaren Stellplatzes für die Spinnereivorbereitungsmaschine kann hierbei besonders effizient ausgenutzt werden, wobei die einzelnen Komponenten der Spinnereivorbereitungsmaschine auch weiterhin gut zugänglich sind. Die Spulvorrichtung und/oder die Hülsentransfervorrichtung sind zumindest teilweise unterhalb der Führung, unterhalb des Streckwerks und/oder unterhalb des Verfestigungsmittels angeordnet. In der Seitenansicht der Spinnereivorbereitungsmaschine sind die Führung und vorzugsweise auch das Verfestigungsmittel somit oberhalb der Spulvorrichtung und der sich insbesondere in etwa auf gleicher Höhe befindlichen Hülsentransfervorrichtung angeordnet. Der Faserverband wird in diesem Fall über die Führung horizontal oder schräg nach unten ins Streckwerk geführt. Von dort gelangt er, vorzugsweise schräg nach unten, in das Verfestigungsmittel. Das dort aus dem Faserverband hergestellt Vorgarn wird schließlich mit Hilfe der Spulvorrichtung (die sich vorzugsweise in Bodennähe des die Spinnereivorbereitungsmaschine tragenden Hallenbodens befindet) auf eine Hülse aufgespult, die schließlich mit Hilfe der Hülsentransportvorrichtung auf die sich ebenfalls in Bodennähe befindliche Hülsentransporteinrichtung übergeben wird.Likewise, it brings advantages when the winding device and / or the tube transfer device are arranged in a plan view and / or a side view of the spinning preparation machine at least partially between the feed section of the guide and the solidifying agent. The solidifying agent may in this case be arranged in the region of a front end region of the spinning preparation machine, while the feeding section may be in the region of a second, rear end-side end portion, said end portions should be placed on opposite sides of the transport path (s). Finally, it is also conceivable for the winding device and / or the tube transfer device to be arranged at least partially between the feed section of the guide and the drafting device in the above-mentioned plan view and / or side view. The utilization of the available parking space for the spinning preparation machine can be exploited particularly efficiently, with the individual components of the spinning preparation machine continue to be easily accessible. The winding device and / or the tube transfer device are at least partially disposed below the guide, below the drafting system and / or below the solidifying agent. In the side view of the spinning preparation machine, the guide and preferably also the solidifying agent are thus arranged above the winding device and the sleeve transfer device located in particular approximately at the same height. The fiber structure is in this case on the guide horizontally or obliquely down into the drafting system guided. From there it enters the solidifying agent, preferably obliquely downwards. The roving produced there from the fiber structure is finally wound with the help of the winding device (which is preferably near the bottom of the hall floor supporting the spinning preparation machine) on a sleeve, which is finally transferred with the aid of the tube transporting device to the same located near the bottom sleeve transport device.

Vorteilhaft ist es, wenn der Zuführabschnitt der Führung in horizontaler Richtung wenigstens 50 cm, bevorzugt wenigstens 100 cm, besonders bevorzugt wenigstens 150 cm, von einer Eingangswalze des Streckwerks beabstandet ist. Das Streckwerk umfasst vorzugsweise mehrere Streckwerkswalzenanordnungen, die jeweils eine Walze und zumindest eine Gegenwalze umfassen, um den Faserverband zwischen Walzen und korrespondierenden Gegenwalzen klemmend führen zu können. Ist der Abstand zwischen einer der Eingangswalzen (d. h. der Walzen des Streckwerks, die dem Abgabeabschnitt der Führung am nächsten sind) und dem Zuführabschnitt entsprechend den obigen Angaben bemessen, so kann bzw. können die Transportbahn(en) (in der Draufsicht der Spinnereivorbereitungsmaschine) problemlos zwischen Zuführabschnitt und Eingangswalze verlaufen.It is advantageous if the feed section of the guide in the horizontal direction at least 50 cm, preferably at least 100 cm, more preferably at least 150 cm, is spaced from an input roller of the drafting system. The drafting arrangement preferably comprises a plurality of drafting roller arrangements, each comprising a roller and at least one counter-roller, in order to be able to clamp the fiber structure between rollers and corresponding counter-rollers. If the distance between one of the input rollers (ie, the rollers of the drafting system which are closest to the delivery section of the guide) and the delivery section is dimensioned in accordance with the above, the transport path (s) (in the plan view of the spinning preparation machine) can be easily arranged Run between feed and input roller.

Besonders vorteilhaft ist es, wenn das Streckwerk und die Führung und/oder das Streckwerk und die Spulvorrichtung und/oder das Streckwerk und die Hülsentransfervorrichtung in einer Seitenansicht der Spinnereivorbereitungsmaschine in horizontaler Richtung gesehen auf derselben Seite des Verfestigungsmittels angeordnet sind. Vorzugsweise weist das Verfestigungsmittel in der genannten Seitenansicht in horizontaler Richtung gesehen den größten Abstand zu der bzw. den Transportbahn(en) auf. Nach Verlassen des Verfestigungsmittels wird das Vorgarn vorzugsweis bezogen auf die Horizontale in Richtung der Spulvorrichtung und/oder der Hülsentransporteinrichtung umgelenkt und verläuft hierbei zumindest in horizontaler Richtung entgegen der Transportrichtung des im Bereich der Führung geführten Faserverbands.It is particularly advantageous if the drafting system and the guide and / or the drafting device and the winding device and / or the drafting device and the sleeve transfer device are arranged in a side view of the spinning preparation machine in the horizontal direction on the same side of the solidifying agent. Preferably, the solidification agent in the said side view in the horizontal direction has the greatest distance to the or the transport path (s). After leaving the solidifying agent, the roving is preferably deflected relative to the horizontal in the direction of the winding device and / or the sleeve transport device and in this case runs at least in the horizontal direction against the transport direction of the guided in the region of the fiber guide.

Ebenso bringt es Vorteile mit sich, wenn die Spulvorrichtung, die Hülsentransfervorrichtung, das Streckwerk, die Führung und/oder die Transportbahn(en) in einer Frontansicht der Spinnereivorbereitungsmaschine zumindest teilweise hinter dem Verfestigungsmittel angeordnet sind. Insbesondere, wenn sämtliche der genannten Einheiten (mit Ausnahme des Verfestigungsmittels) hinter dem Verfestigungsmittel liegen, ist diese von vorne leicht zugänglich. Sich in dem Verfestigungsmittel befindliche Faserreste können nach einer ungewollten Unterbrechung der Vorgarnherstellung leicht aus dem Verfestigungsmittel entfernt werden. Ferner ist es von Vorteil, wenn die Transportbahn(en) in der genannten Frontansicht hinter dem Verfestigungsmittel, der Spulvorrichtung und der Hülsentransfervorrichtung verläuft bzw. verlaufen, so dass diese von hinten zugänglich ist bzw. sind.Likewise, it brings advantages when the winding device, the sleeve transfer device, the drafting system, the guide and / or the transport path (s) in a front view the spinning preparation machine are at least partially disposed behind the solidifying agent. In particular, when all of the said units (with the exception of the solidifying agent) are behind the solidifying agent, this is easily accessible from the front. Residual fibers present in the solidifying agent can easily be removed from the solidifying agent following an unwanted interruption of the roving production. Further, it is advantageous if the transport path (s) run in the mentioned front view behind the solidifying agent, the winding device and the sleeve transfer device or run so that it is accessible from the rear or are.

Besonders vorteilhaft ist es, wenn der Zuführabschnitt in einer Frontansicht der Spinnereivorbereitungsmaschine hinter dem Streckwerk, hinter dem Abgabeabschnitt der Führung, hinter der Spulvorrichtung, hinter der Hülsentransfervorrichtung, hinter wenigstens einer Transportbahn und/oder hinter der gesamten unterhalb der Führung verlaufenden Hülsentransporteinrichtung angeordnet ist. Der Zuführabschnitt ist in diesem Fall von hinten leicht zugänglich, so dass der Faserverband problemlos aus einem den Faserverband bereitstellenden Behälter entnehmbar und der Führung zuführbar ist.It is particularly advantageous if the feed section is arranged in a front view of the spinning preparation machine behind the drafting system, behind the discharge section of the guide, behind the winding device, behind the tube transfer device, behind at least one transport path and / or behind the entire sleeve transport device extending below the guide. In this case, the feed section is easily accessible from the rear, so that the fiber structure can be easily removed from a container providing the fiber structure and fed to the guide.

Die Spinnereivorbereitungsmaschine 1 umfasst vorzugsweise ein Streckwerk 5 mit mehreren korrespondierenden Streckwerkswalzen (lediglich eine der beiden im Eingangsbereich des Streckwerks 5 angeordneten Eingangswalzen 15 ist mit einem Bezugszeichen versehen), welches mit einem Faserverband 4, beispielsweise in Form eines doublierten Streckenbands, beliefert wird. FIG. 1 shows a schematic side view of an inventive, standing on a hall floor 20, spinning preparation machine 1 in the form of an air spinning machine, which serves to produce roving 3. The spinning preparation machine 1 preferably comprises a drafting device 5 with a plurality of corresponding drafting rollers (only one of the two arranged in the entrance of the drafting 5 input rollers 15 is provided with a reference numeral), which with a fiber structure 4, for example in the form of a relined tape, is supplied.

Der Faserverband 4 stammt in der Regel aus einem Behälter 7 (z. B. einer Spinnkanne) und wird dem Streckwerk 5, vorzugsweise nach Passieren einer Führungsrolle 21, über eine Führung 6 zugeführt, wobei die Führung 6 beispielsweise als längliches Profil ausgebildet sein kann. Die Führung 6 umfasst prinzipiell einen dem Behälter 7 benachbarten Zuführabschnitt 8, einen dem Streckwerk 5 benachbarten Abgabeabschnitt 9 und einen dazwischen liegenden Führungsabschnitt 14, um den Faserverband 4 zumindest nach unten hin abzustützen.The fiber structure 4 as a rule comes from a container 7 (eg a spinning can) and is fed to the drafting device 5, preferably after passing a guide roller 21, via a guide 6, wherein the guide 6 can be designed, for example, as an elongated profile. In principle, the guide 6 comprises a feed section 8 adjacent to the container 7, a dispensing section 9 adjacent to the drafting device 5 and a guide section 14 located therebetween in order to support the fiber structure 4 at least downwards.

Ferner umfasst die gezeigte Spinnereivorbereitungsmaschine 1 ein von dem Streckwerk 5 beabstandetes Verfestigungsmittel in Form einer Luftspinndüse 2 mit einer innenliegenden, aus dem Stand der Technik bekannten und daher nicht dargestellten Wirbelkammer und einem ebenfalls bekannten und daher ebenfalls nicht dargestellten, in die Wirbelkammer ragenden Garnbildungselement in Form einer Hohlspindel. In der Wirbelkammer wird der Faserverband 4 bzw. mindestens ein Teil der Fasern des Faserverbands 4 mit Hilfe einer in der Wirbelkammer durch Luftdüsen erzeugten Wirbelluftströmung mit einer Schutzdrehung versehen.Further, the spinning preparation machine 1 shown comprises a spaced apart from the drafting 5 solidification agent in the form of an air-jet nozzle 2 with an internal, known from the prior art and therefore not shown vortex chamber and a likewise known and therefore also not shown, projecting into the vortex chamber Garnbildelement in shape a hollow spindle. In the vortex chamber, the fiber structure 4 or at least part of the fibers of the fiber composite 4 is provided with a protective rotation by means of a vortex air flow generated in the vortex chamber by air nozzles.

Die Spinnereivorbereitungsmaschine 1 kann darüber hinaus eine dem Streckwerk 5 in der gezeigten Transportrichtung T nachgeordnete Abzugseinheit für das Vorgarn 3 mit vorzugsweise zwei Abzugswalzen umfassen (die Abzugseinheit ist nicht zwingend notwendig und daher in den Figuren nicht gezeigt). Des Weiteren ist eine Spulvorrichtung 10 vorhanden, die vorzugsweise der Aufnahme von wenigstens zwei Hülsen 11 dient und mit deren Hilfe das Vorgarn 3 auf eine Hülse 11 aufspulbar ist, wobei das Vorgarn 3 hierbei mit Hilfe einer in Richtung des in Figur 1 gezeigten Doppelpfeils hin und her bewegbaren Changiereinheit 18 geführt wird. Die Spulvorrichtung 10 kann insbesondere eine mit Hilfe eines Antriebs drehbare Plattform 17 umfassen, auf der die Hülsen 11 über entsprechende, nicht näher gezeigte, Haltevorrichtungen fixiert werden können, wobei die Haltevorrichtungen und damit auch die jeweiligen Hülsen 11, vorzugsweise über separate Antriebe, in eine Drehbewegung versetzbar sind.The spinning preparation machine 1 can moreover comprise a draw unit for the roving 3, preferably downstream of the drafting unit 5, in the transport direction T shown, preferably with two draw-off rollers (the withdrawal unit is not absolutely necessary and therefore not shown in the figures). Furthermore, a winding device 10 is provided, which preferably serves to receive at least two sleeves 11 and with the aid of the roving 3 can be wound on a sleeve 11, wherein the roving 3 in this case with the aid of a in the direction of FIG. 1 shown double arrow back and forth movable traversing unit 18 is guided. The winding device 10 may in particular comprise a rotatable by means of a drive platform 17 on which the sleeves 11 can be fixed via corresponding, not shown, holding devices, wherein the holding devices and thus the respective sleeves 11, preferably via separate drives in a Rotary movement are offset.

Die gezeigte und beispielhaft als Luftspinnmaschine ausgebildete Spinnereivorbereitungsmaschine 1 arbeitet nach einem speziellen Luftspinnverfahren. Zur Bildung des Vorgarns 3 wird der Faserverband 4 in der genannten Transportrichtung T über eine nicht gezeigte Einlassöffnung in die Wirbelkammer der Luftspinndüse 2 geführt. Dort erhält er eine Schutzdrehung, d. h. mindestens ein Teil der Fasern des Faserverbands 4 wird von der genannten Wirbelluftströmung, die durch entsprechend platzierte Spinnluftkanäle erzeugt wird, erfasst. Ein Teil der Fasern wird hierbei aus dem Faserverband 4 zumindest ein Stück weit herausgezogen und um die Spitze des in die Wirbelkammer ragenden Garnbildungselements gewunden.The spinning preparation machine 1 shown and exemplified as an air-spinning machine operates according to a special air-spinning method. To form the roving 3, the fiber structure 4 is guided in the transport direction T via an inlet opening, not shown, into the swirl chamber of the air-jet nozzle 2. There he receives a protective rotation, d. H. at least a portion of the fibers of the fiber composite 4 is detected by said vortex air flow generated by appropriately positioned spinning air channels. A part of the fibers is hereby pulled out of the fiber structure 4 at least a little bit and wound around the tip of the yarn formation element projecting into the vortex chamber.

Letztendlich werden die Fasern des Faserverbands 4 über eine Eintrittsöffnung des Garnbildungselements und einen innerhalb des Garnbildungselements angeordneten und sich an die Eintrittsöffnung anschließenden Abzugskanal aus der Wirbelkammer abgezogen. Hierbei werden schließlich auch die freien Faserenden auf einer Spiralbahn in Richtung der Eintrittsöffnung gezogen und schlingen sich dabei als Umwindefasern um die zentral verlaufenden Kernfasern - resultierend in einem die gewünschte Schutzdrehung aufweisenden Vorgarn 3.Finally, the fibers of the fiber composite 4 are withdrawn from the vortex chamber via an inlet opening of the yarn formation element and a withdrawal channel arranged inside the yarn formation element and adjoining the inlet opening. In this case, finally, the free fiber ends are drawn on a spiral path in the direction of the inlet opening and loop as Umwindefasern to the centrally extending core fibers - resulting in a desired protective rotation having roving. 3

Das Vorgarn 3 besitzt durch die nur teilweise Verdrehung der Fasern eine Verzugsfähigkeit, die für die Weiterverarbeitung des Vorgarns 3 in einer nachfolgenden Spinnmaschine, beispielsweise einer Ringspinnmaschine, unerlässlich ist. Konventionelle Luftspinnvorrichtungen erteilen dem Faserverband 4 hingegen eine derart starke Drehung, dass der notwendige Verzug im Anschluss an die Garnherstellung nicht mehr möglich ist. Dies ist in diesem Fall auch erwünscht, da herkömmliche Luftspinnmaschinen ausgelegt sind, ein fertiges Garn herzustellen, das sich in der Regel durch eine hohe Festigkeit auszeichnen soll.The roving 3 has by the only partial rotation of the fibers a delaying ability, which is essential for the further processing of the roving 3 in a subsequent spinning machine, such as a ring spinning machine. By contrast, conventional air-spinning devices impart to the fiber structure 4 such a strong rotation that the necessary distortion following the yarn production is no longer possible. This is also desirable in this case, since conventional air spinning machines are designed to produce a finished yarn, which should usually be characterized by a high strength.

Wie bereits oben ausgeführt, wird das Vorgarn 3 nach Verlassen der Luftspinndüse 2 mit Hilfe der Spulvorrichtung 10 auf eine Hülse 11 aufgespult. Ist die entsprechende Hülse 11 ausreichend mit Vorgarn 3 bespult, so erfolgt ein Austausch durch eine leere Hülse 11, wobei hierfür die genannte Plattform 17 um eine vorzugsweise vertikale Drehachse gedreht wird, bis sich die in Figur 1 gezeigte leere Hülse 11 auf der Position der in Figur 1 gezeigten bespulten Hülse 11 befindet und umgekehrt.As already stated above, the roving 3 is wound on a sleeve 11 after leaving the air-jet nozzle 2 with the aid of the winding device 10. If the corresponding sleeve 11 sufficiently insufflated with roving 3, it is replaced by an empty sleeve 11, for which purpose said platform 17 is rotated about a preferably vertical axis of rotation until the in FIG. 1 shown empty sleeve 11 in the position the in FIG. 1 shown bespulten sleeve 11 and vice versa.

Während im Anschluss an diesen Hülsenwechsel die leere Hülse 11 mit Vorgarn 3 bespult wird, wird eine Hülsentransfervorrichtung 16 aktiviert, die die bespulte Hülse 11 an eine Transportbahn 13 (beispielsweise in Form eines Transportbandes) einer Hülsentransporteinrichtung 12 übergibt, die die Hülse 11 schließlich an eine nicht gezeigte Entnahmestelle transportiert. Die entsprechende Transportbahn 13, von der mehrere vorhanden sein können, umfasst vorzugsweise mehrere Hülsenhalter 19, mit deren Hilfe die Hülsen 11 während ihres Transports gehalten werden können. Nach Abtransport der bespulten Hülse 11 kann die hierdurch frei gewordene Position auf der Plattform 17 der Spulvorrichtung 10 mit einer neuen leeren Hülse 11 bestückt werden, wobei dies vorzugsweise ebenfalls durch die Hülsentransfervorrichtung 16 erfolgt.While following this sleeve change, the empty tube 11 is spooled with roving 3, a sleeve transfer device 16 is activated, which transfers the spooled sleeve 11 to a transport path 13 (for example in the form of a conveyor belt) a sleeve transport device 12, the sleeve 11 finally to a Transported not shown removal point. The corresponding transport path 13, of which several may be present, preferably comprises a plurality of sleeve holders 19, by means of which the sleeves 11 can be held during their transport. After removal of the bespulten sleeve 11, thereby vacated position on the platform 17 of the winding device 10 can be equipped with a new empty shell 11, which preferably also takes place through the sleeve transfer device 16.

Alternativ könnte die Spulvorrichtung 10 auch nur über eine Haltevorrichtung für eine Hülse 11 verfügen.Alternatively, the winding device 10 could also have only a holding device for a sleeve 11.

Erfindungsgemäß wird nun vorgeschlagen, dass die Transportbahn(en) 13 in einer in Figur 2 gezeigten Draufsicht der Spinnereivorbereitungsmaschine 1 zumindest teilweise zwischen dem Zuführabschnitt 8 der Führung 6 und dem Streckwerk 5 angeordnet ist bzw. sind. Insbesondere sollte(n) die Transportbahn(en) 13 hierbei im Bereich des genannten Hallenbodens 20 abgestützt sein, so dass sich diese in der in Figur 1 gezeigten Seitenansicht der Spinnereivorbereitungsmaschine 1 unterhalb der Führung 6 befindet bzw. befinden.According to the invention it is now proposed that the transport path (s) 13 in a in FIG. 2 shown plan view of the spinning preparation machine 1 is at least partially disposed between the feed section 8 of the guide 6 and the drafting 5 or are. In particular, the transport track (s) 13 should in this case be supported in the area of said hall floor 20, so that these are located in the in-hall FIG. 1 shown side view of the spinning preparation machine 1 below the guide 6 is or are located.

Zudem ist es von Vorteil, wenn die Transportbahn(en) 13 zwischen dem Zuführabschnitt 8 der Führung 6 bzw. dem Behälter 7 und dem Abgabeabschnitt 9 der Führung 6 angeordnet ist bzw. sind, wobei die Führung 6 die Transportbahn(en) 13 brückenartig überspannt. Der Faserverband 4 wird hierbei von hinten über die Transportbahn(en) 13 geführt und gelangt schließlich im vorderen Bereich der Spinnereivorbereitungsmaschine 1 in das Streckwerk 5 und letztendlich in die Luftspinndüse 2.In addition, it is advantageous if the transport path (s) 13 between the feed section 8 of the guide 6 and the container 7 and the discharge section 9 of the guide 6 is or are arranged, wherein the guide 6 spans the transport path (s) 13 like a bridge , The fiber structure 4 is in this case guided from behind over the transport path (s) 13 and finally arrives in the front area of the spinning preparation machine 1 in the drafting device 5 and finally in the air-spinneret 2.

Wie Figur 2 zeigt, können die Spulvorrichtung 10, die Changiereinheit 18 und die Hülsentransfereinrichtung 16 seitlich des Streckwerks 5 bzw. der Luftspinndüse 2 angeordnet sein. In diesem Fall ergibt sich eine besonders platzsparende Anordnung der einzelnen Elemente.As FIG. 2 1, the winding device 10, the traversing unit 18, and the sleeve transfer device 16 be arranged laterally of the drafting 5 and the Luftspinndüse 2. In this case, there is a particularly space-saving arrangement of the individual elements.

Ferner sollten das Streckwerk 5, die Luftspinndüse 2 und auch die Führung 6 oberhalb der Spulvorrichtung 10, der Changiereinheit 18, der Hülsentransfereinrichtung 16 und/oder der Transportbahn(en) 13 platziert sein, um den Freiraum oberhalb der zuletzt genannten Elemente auszunutzen.Furthermore, the drafting device 5, the air-jet nozzle 2 and also the guide 6 should be placed above the winding device 10, the traversing unit 18, the sleeve transfer device 16 and / or the transport path (s) 13 in order to utilize the clearance above the latter elements.

Abschließend wird hinsichtlich der möglichen gegenseitigen Anordnungen der einzelnen Abschnitte (Zuführabschnitt 8, Führungsabschnitt 14, Abgabeabschnitt 9, Streckwerk 5, Luftspinndüse 2, Changiereinheit 18, Spulvorrichtung 10, Hülsentransfervorrichtung 16, Transportbahn(en) 13) auf die obige Beschreibung verwiesen, so dass die in den Figuren gezeigte gegenseitige Anordnung nur beispielhaft zu verstehen ist.Finally, with regard to the possible mutual arrangements of the individual sections (feed section 8, guide section 14, discharge section 9, drafting device 5, air spinning nozzle 2, traversing unit 18, winding device 10, sleeve transfer device 16, transport path (s) 13), reference is made to the above description, so that the to be understood in the figures shown mutual arrangement only by way of example.
