Description

Die Erfindung betrifft eine Spinnvorrichtung zur Herstellung eines Fadens mittels eines umlaufenden Luftstroms gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a spinning device for producing a thread by means of a circulating air flow according to the preamble of claim 1.

Luftspinnvorrichtungen zur Herstellung textiler Fäden sind in verschiedenen Ausführungsformen bekannt und in der Patentliteratur beschrieben.Air-spun devices for producing textile threads are known in various embodiments and described in the patent literature.

In der DE 40 36 119 C2 ist beispielsweise eine Luftspinnvorrichtung beschrieben, bei der ein in einem vorgeschalteten Streckwerk verzogenes Faserband durch einen Düsenblock in eine Luftspinnvorrichtung eingeführt wird und über eine Faserbandführung, die auch als Drallstopp wirkt, in die Einlassöffnung einer während des Spinnprozesses rotierenden, über einen Antriebsriemen beaufschlagten Spinnspindel gelangt.
Beim Eintreten des Faserbandes in die rotierende Spinnspindel werden die freien Faserenden mittels eines umlaufenden Luftstroms um den kegelig ausgebildeten Spindelkopf der Spinnspindel geschlungen und wickeln sich während des Einziehens des Fadens in die Spindel spiralförmig um die sogenannten Kernfasern.
Das heißt, die Kernfasern bilden gemeinsam mit den sogenannten Umwindefasern einen neuen Faden.In the DE 40 36 119 C2 For example, an air-spinning device is described in which a sliver warped in an upstream drafting system is introduced through a nozzle block in an air spinning device and passes through a sliver guide, which also acts as a twist stop, into the inlet opening of a spinning spindle which is rotated during the spinning process and acted on by a drive belt.
Upon entry of the sliver in the rotating spinning spindle, the free fiber ends are wound around the conically shaped spindle head of the spinning spindle by means of a circulating air flow and wrap during retraction of the thread in the spindle spirally around the so-called core fibers.
That is, the core fibers together with the so-called Umwindefasern form a new thread.

Nachteilig bei dieser bekannten Luftspinnvorrichtung ist allerdings, dass die Vorrichtung aufgrund ihrer rotierbar gelagerten, angetriebenen Spinnspindel relativ wartungsintensiv ist.A disadvantage of this known air spinning device, however, is that the device rotates due to its stored, driven spinning spindle is relatively maintenance-intensive.

Durch die DE 199 26 492 A1 ist eine vergleichbare Vorrichtung zur Herstellung eines Fadens mittels eines umlaufenden Luftstroms bekannt.
Auch bei dieser Luftspinnvorrichtung wird das zu verspinnende Faserband über eine Faserbandführung und einen Düsenblock in die Luftspinnvorrichtung eingeführt und gelangt in die Einlassöffnung eines stationär angeordneten, hohlen Spinnkonus'.
Das heißt, der Spinnkonus dieser bekannten Luftspinnvorrichtung ist nicht rotierbar gelagert, sondern fest mit dem Gehäuse der Luftspinnvorrichtung verbunden.
Wie vorstehend bereits im Zusammenhang mit der DE 40 36 119 C2 beschrieben, wird das Faserband im Bereich der Einlassöffnung des Spinnkonus' einem umlaufenden Luftstrom ausgesetzt, der die freien Faserenden des Faserbandes um den Kopf des Spinnkonus' legt.
Beim anschließenden Einziehen des Faserbandes in den hohlen Spinnkonus schlingen sich auch bei dieser Vorrichtung die freien Faserenden spiralförmig als sogenannte Umwindefasern um die Kernfasern und bilden dabei einen Faden.By the DE 199 26 492 A1 a comparable device for producing a thread by means of a circulating air flow is known.
Also in this air-spinning device, the fiber sliver to be spun is introduced into the air-spinning device via a sliver guide and a nozzle block and enters the inlet opening of a stationary, hollow spinning cone.
That is, the spinning cone of this known air spinning device is not rotatably mounted, but firmly connected to the housing of the air spinning device.
As already mentioned in connection with the DE 40 36 119 C2 described, the sliver is exposed in the region of the inlet opening of the spinning cone 'a circulating air flow, which lays the free fiber ends of the sliver around the head of the spinning cone'.
During the subsequent retraction of the sliver in the hollow spinning cone, the free fiber ends loop in this device as spiral so-called Umwindefasern to the core fibers and thereby form a thread in this device.

Luftspinnvorrichtungen gemäß DE 199 26 492 A1 zeichnen sich vor allem durch einen relativ einfachen konstruktiven Ausbau aus und sind relativ wartungsarm.
Es hat sich allerdings gezeigt, dass bei solchen Luftspinnvorrichtungen mit einem feststehenden Spinnkonus, obwohl dieser aus hochverschleißfestem Material, vorzugsweise einem technischen Keramikwerkstoff, gefertigt ist, die Gefahr besteht, dass es mit der Zeit in bestimmten Bereichen des Kopfes des Spinnkonus' zu Verschleißspuren kommt, die sich negativ auf die Funktionsfähigkeit der Vorrichtung auswirken.Air spinning devices according to DE 199 26 492 A1 are characterized mainly by a relatively simple structural design and are relatively low maintenance.
However, it has been found that in such air spinning devices with a fixed spinning cone, although this is made of highly wear-resistant material, preferably a technical ceramic material, there is a risk that it will wear over time in certain areas of the head of the spinning cone ', which have a negative effect on the functioning of the device.

Ausgehend von Luftspinnvorrichtungen der vorstehend beschriebenen Gattung, liegt der Erfindung die Aufgabe zugrunde, Luftspinnvorrichtungen mit einem während des Spinnprozesses stationären Spinnkonus dahingehend zu verbessern, dass die Lebensdauer der Einrichtungen, insbesondere die Lebensdauer des stark beanspruchten Spinnkonus' deutlich verlängert wird.Starting from air spinning devices of the type described above, the invention has for its object to improve air spinning devices with a stationary during the spinning spinning spinning cone to the effect that the life of the devices, in particular the life of the highly stressed spinning cone 'is significantly extended.

Diese Aufgabe wird erfindungsgemäß durch eine Spinnvorrichtung gelöst, die die im Anspruch 1 beschriebenen Merkmale aufweist.This object is achieved by a spinning device having the features described in claim 1.

Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous embodiments of the invention are the subject of the dependent claims.

Die erfindungsgemäße Ausbildung einer Luftspinnvorrichtung mit einem Spinnkonus, der bezüglich seiner Einbauwinkellage einstellbar ist, hat den Vorteil, dass während der Einsatzzeit der Spinnvorrichtung auf einfache Weise die Lage des Spinnkonus' in seiner Lageranordnung mehrfach geändert und so verhindert werden kann, dass es punktuell zu Überbeanspruchungen des Spinnkonusmaterials kommt, was zu einem vorzeitigen Verschleiß des Spinnkonus' führen würde.
Das heißt, durch wiederholtes Drehen des Spinnkonus' um seine Längsachse, vorzugsweise um einen oder mehrere Winkelgrad(e), beispielsweise zufällig im Zuge einer Spinnunterbrechung, bei jeder Spinnunterbrechung oder auch in periodischen Zeitabständen, können die Auftreffstellen der durch die Blasdüsen eingeleiteten, im Bereich des Kopfes auf den Spinnkonus treffenden Luftströme, die in erster Linie für den erhöhten Verschleiß verantwortlich sind, nach und nach über den ganzen Umfang des Spinnkonus' verteilt werden.The inventive construction of an air spinning device with a spinning cone, which is adjustable with respect to its installation angle, has the advantage that during the period of use of the spinning device in a simple manner, the position of the spinning cone 'changed its bearing arrangement several times and can be prevented so that it selectively to overstress of the spinning cone material, which would lead to premature wear of the spinning cone.
That is, by repeatedly rotating the spinning cone about its longitudinal axis, preferably by one or more angular degrees (e), for example, coincidentally in the course of a spinning interruption, at each spinning interruption or at periodic intervals, the impact of introduced through the blowing nozzles, in the area of the head on the spinning cone impinging air streams, which are primarily responsible for the increased wear, are gradually distributed over the entire circumference of the spinning cone '.

Auf diese Weise wird eine besonders hohe Materialbeanspruchung einzelner Stellen des Spinnkonus' erfolgreich verhindert und sichergestellt, dass im Laufe der Zeit der gesamte Umfang des Spinnkonuskopfes nahezu gleichmäßig beansprucht wird.In this way, a particularly high material stress of individual points of the spinning cone 'successfully prevented and ensured that over time, the entire circumference of the spinning cone head is claimed almost uniformly.

Vorteilhafterweise ist der Spinnkonus, wie im Anspruch 2 beschrieben, beispielsweise über eine Spielpassung drehbar im hinteren Lagergehäuse des Außengehäuses der Luftspinnvorrichtung gelagert und wird, im Bedarfsfall leicht lösbar, über eine Permanentmagnetanordnung in der gewünschten Einbauwinkellage am Außengehäuse festgelegt.
Eine solche relativ einfache und robuste Konstruktion gewährleistet einerseits eine sichere Fixierung des Spinnkonus' während des Spinnprozesses und ermöglicht es dem Bedienpersonal anderseits, die Einbauwinkellage des Spinnkonus' problemlos, vorzugsweise ereignis- oder zeitbezogen aber auch zufällig, zu verstellen.Advantageously, the spinning cone, as described in claim 2, for example, via a clearance fit rotatably mounted in the rear bearing housing of the outer casing of the air spinning device and, if necessary, easily detachable, set via a permanent magnet assembly in the desired installation angle position on the outer housing.
Such a relatively simple and robust construction on the one hand ensures a secure fixation of the spinning cone 'during the spinning process and allows the operator on the other hand, the installation angle position of the spinning cone' easily, preferably event or time related but also random to adjust.

Wie im Anspruch 3 dargelegt, erfolgt die Verstellung der Einbauwinkellage des Spinnkonus', die vorzugsweise jeweils lediglich einige Winkelgrade beträgt, in vorteilhafter Ausführungsform durch das Bedienpersonal per Hand.
Ein solchermaßen manuell einstellbarer Spinnkonus ist einerseits kostengünstig zu fertigen und andererseits durch das Bedienpersonal leicht zu bedienen.As set forth in claim 3, the adjustment of the installation angle position of the spinning cone ', which is preferably only a few degrees, in an advantageous embodiment by the operator by hand.
Such a manually adjustable spinning cone is on the one hand inexpensive to manufacture and on the other hand easy to operate by the operator.

In bevorzugter Ausführungsform weist der Spinnkonus außerdem, wie im Anspruch 4 beschrieben, eine Markierung auf, aus der die jeweilige Einbauwinkellage des Spinnkonus' in der Lageranordnung leicht erkennbar ist.
Durch eine solche Markierung ist, beispielsweise durch einen einfachen Vergleich der Einbauwinkellage des betreffenden Spinnkonus' mit der Einbauwinkellage benachbarter Spinnkoni, sofort feststellbar, ob der betreffende Spinnkonus bereits turnusmäßig in seine neue Winkellage gedreht wurde oder ob bislang versäumt wurde, diesen Spinnkonus in die neue Position zu drehen.
Das heißt, eine solche Markierung erleichtert das gleichmäßige Einstellen der Einbau-Winkellagen der Spinnkoni erheblich.In a preferred embodiment, the spinning cone also, as described in claim 4, a mark from which the respective installation angle position of the spinning cone 'in the bearing assembly is easily recognizable.
By such a marking is, for example, by a simple comparison of the installation angle of the respective spinning cone 'with the installation angle position adjacent Spinnkoni, immediately detectable whether the spinner cone in question was already rotated in its new angular position or whether so far failed to turn this spinning cone in the new position.
That is, such a mark facilitates the uniform adjustment of the installation angular positions of Spinnkoni considerably.

Gemäß Anspruch 5 ist die Markierung vorzugsweise an einem Stellring angeordnet, der am hinteren Ende des Spinnkonus' drehfest am Spinnkonus angeordnet und so ausgebildet ist, dass der Spinnkonus bezüglich seiner Einbau-Winkellage leicht manuell verstellt werden kann.According to claim 5, the marking is preferably arranged on a collar, which is arranged at the rear end of the spinning cone 'rotationally fixed to the spinning cone and formed so that the spinning cone with respect to its installation angular position can be easily adjusted manually.

In einer alternativen Ausführungsform verfügt der Spinnkonus, wie im Anspruch 6 beschrieben, über eine Einrichtung, die durch ein selbsttätig arbeitendes Bedienaggregat betätigbar ist.
Diese Einrichtung, beispielsweise eine auf dem Außenumfang des Stellringes angeordnete Verzahnung, kann durch eine entsprechende Handhabungseinrichtung des Bedienaggregates beaufschlagt werden.
Das heißt, das selbsttätig arbeitende Bedienaggregat, vorzugsweise ein entlang der Arbeitsstellen der Textilmaschine patrouillierender Bedienläufer (Anspr.7) kann mittels einer entsprechenden Handhabungsvorrichtung die Einbauwinkellage des Spinnkonus' definiert einstellen und bei Bedarf jederzeit ändern.In an alternative embodiment, the spinning cone has, as described in claim 6, a device which can be actuated by an automatically operating control unit.
This device, for example, arranged on the outer circumference of the adjusting ring teeth can be acted upon by a corresponding handling device of the operating unit.
That is, the automatically operating control unit, preferably a along the workstations of the textile machine patrolling the operator (Anspr.7) can set by means of a corresponding handling device, the installation angle position of the spinning cone 'defined and change anytime as needed.

Weitere Einzelheiten der Erfindung sind nachfolgend anhand eines in den Zeichnungen dargestellten Ausführungsbeispiels erläutert.Further details of the invention are explained below with reference to an embodiment shown in the drawings.

Das Expansionsgehäuse 16 bildet dabei in Verbindung mit dem vorderen Gehäuseteil 14 des Außengehäuses einen vorderen Ringraum 20, der über eine Pneumatikleitung 21 an eine Überdruckquelle 22 angeschlossen ist und in Verbindung mit dem hinteren Gehäuseteil 15 des Außengehäuses einen Expansionsraum 28.
Während der Expansionsraum 28 über eine Luftaustrittsöffnung 29 an die Atmosphäre angeschlossen ist, ist der Ringraum 20 pneumatisch durchgängig mit Blasluftdüsen 23 verbunden, die im Düsenblock 17 angeordnet sind.
Die Blasluftdüsen 23 sind dabei im Bereich der Eintrittsöffnung 35 des Spinnkonus' 19 tangential so auf den Kopf 24 des Spinnkonus' 19 gerichtet, dass sich eine rotierende Luftströmung einstellt.FIG. 2 shows the air-spinning device 5 according to the invention, the drafting device 4 upstream of the sliver running direction R and the downstream yarn withdrawal device 6.

While the expansion space 28 is connected via an air outlet opening 29 to the atmosphere, the annular space 20 is pneumatically connected continuously with Blasluftdüsen 23, which are arranged in the nozzle block 17.
The blowing air nozzles 23 are directed tangentially in the region of the inlet opening 35 of the spinning cone 19 in such a way on the head 24 of the spinning cone 19 that a rotating air flow is established.

Der Spinnkonus 19 ist des Weiteren über eine Lageranordnung 30, die in der Rückwand 31 des hinteren Gehäuseteils 15 angeordnet ist, um seine Mittellängsachse relativ zum Außengehäuse 14, 15 drehbar, gelagert.The spinning cone 19 is further supported by a bearing assembly 30, which is arranged in the rear wall 31 of the rear housing part 15, about its central longitudinal axis relative to the outer housing 14, 15 rotatably supported.

Der Spinnkonus 19, der vorzugsweise aus einem hochverschleißfesten Material, beispielsweise einem technischen Keramikwerkstoff gefertigt ist, weist außerdem, in Faserbandlaufrichtung R gesehen, ausgangsseitig einen Stellring 32 mit einer Markierung 34 auf.The spinning cone 19, which is preferably made of a highly wear-resistant material, such as a technical ceramic material, also has, seen in sliver R direction, on the output side a collar 32 with a marker 34.

Der Stellring 32, der aus einem ferromagnetischen Material, vorzugsweise Stahl, gefertigt ist, ist fest mit dem Spinnkonus 19 verbunden und korrespondiert mit einem oder mehreren Permanentmagnet(en) 33 der/die in die Rückwand 31 des Gehäuseteils 15 eingelassen ist/sind.The adjusting ring 32, which is made of a ferromagnetic material, preferably steel, is fixedly connected to the spinning cone 19 and corresponds to one or more permanent magnet (s) 33 which is / are inserted into the rear wall 31 of the housing part 15.

Funktion der erfindungsgemäßen Luftspinnvorrichtung:Function of the air-spinning device according to the invention:

Wie in Fig. 2 angedeutet, durchläuft das in einer Spinnkanne 3 bevorratete Faserband 25 auf seinem Weg zur Kreuzspule 9 zunächst das Streckwerk 4, wo es relativ stark verzogen wird. Über das Ausgangswalzenpaar 26 des Streckwerks 4 wird das verstreckte Faserband 25 in den Bereich der Eingangsöffnung 27 der Luftspinnvorrichtung 5 überführt und unter dem Einfluss einer dort anstehenden Unterdruckströmung in die Luftspinnvorrichtung 5 eingesaugt.
Innerhalb der Luftspinnvorrichtung 5 gelangt das Faserband 25 über die Faserbandführungs- und Drallstoppeinrichtung 18 sowie den Düsenblock 17 zur Eintrittöffnung 35 des hohlen Spinnkonus' 19 und wird durch den sich innerhalb des Spinnkonus' 19 gebildeten Faden 36 in den Spinnkonus 19 hineingezogen.
Das Faserband 25 ist dabei im Bereich des Kopfes 24 des Spinnkonus' 19 dem Einfluss einer Rotationsströmung ausgesetzt. Das heißt, nach dem Verlassen der Faserbandführungs- und Drallstoppeinrichtung 18 werden die hinteren, freien Enden der Randfasern des Faserbandes 25 so der Wirkung eines aus den Blasluftdüsen 23 des Düsenblocks 17 austretenden Luftstromes ausgesetzt, dass sie vom Faserband 25 abgehoben beziehungsweise gelöst werden.
Die vorderen Enden der Faser werden hingegen nicht abgelöst, da sie bereits von Umwindefasern eingefangen und in den hohlen Spinnkonus 19 eingeführt sind.As indicated in Fig. 2, the stockpiled in a spinning can 3 sliver 25 passes through on its way to the cheese 9, first the drafting system 4, where it is relatively distorted. The drawn sliver 25 is transferred into the area of the inlet opening 27 of the air spinning device 5 via the pair of delivery rollers 26 of the drafting system 4 and is sucked into the air spinning device 5 under the influence of a vacuum flow prevailing there.
Within the air spinning device 5, the fiber sliver 25 passes through the sliver guide and swirl stop device 18 and the nozzle block 17 to the inlet opening 35 of the hollow spinning cone '19 and is drawn by the formed inside the spinning cone' 19 thread 36 into the spinning cone 19.
The sliver 25 is exposed to the influence of a rotational flow in the region of the head 24 of the spinning cone 19. That is, after leaving the Faserbandführungs- and twist stop means 18, the rear, free ends of the edge fibers of the sliver 25 are exposed to the action of an emerging from the Blasluftdüsen 23 of the nozzle block 17 air flow that they are lifted or released from the sliver 25.
The front ends of the fiber, on the other hand, are not detached because they are already trapped by binding fibers and inserted into the hollow spinning cone 19.

Die vom Faserband 25 abgelösten freien Faserenden werden durch den rotierenden Luftstrom um den kegeligen Kopf 24 des Spinnkonus' 19 geschlungen.
Durch die kontinuierliche Bewegung des Faserbandes 24 in Faserbandlaufrichtung R wird das rückwärtige freie Ende der Fasern 24 fortlaufend in den hohlen Spinnkonus 19 eingezogen, wobei die Randfasern schraubenförmig um die Kernfasern des Faserbandes 25 geschlungen werden.
Der dabei entstehende Faden 36 wird über die Fadenabzugseinrichtung 6 aus der Luftspinnvorrichtung 5 gezogen und anschließend zu einer Kreuzspule 9 aufgewickelt.The detached from the sliver 25 free fiber ends are wound by the rotating air flow around the conical head 24 of the spinning cone '19.
Due to the continuous movement of the sliver 24 in sliver direction R, the rear free end of the fibers 24 is continuously drawn into the hollow spinning cone 19, wherein the edge fibers are helically wound around the core fibers of the sliver 25.
The resulting thread 36 is pulled over the thread withdrawal device 6 from the air spinning device 5 and then wound into a cheese 9.

Der Spinnkonus 19 ist in einer Lageranordnung 30, beispielsweise einer einfachen Spielpassung, drehbar im hinteren Gehäuseteil 15 des Außengehäuses der Luftspinnvorrichtung 5 gelagert und während des Spinnprozesses magnetisch in seiner jeweiligen Einbauwinkellage fixierbar.
Das heißt, im Gegensatz zu bekannten Luftspinnvorrichtungen, bei denen aufgrund eines feststehenden Düsenblocks und eines feststehenden Spinnkonus' stets die Gefahr besteht, dass der Spinnkonus auf Dauer an exponierten Stellen extrem abgenutzt wird, kann bei der erfindungsgemäßen Luftspinnvorrichtung 5 der Spinnkonus 19 bezüglich seiner Einbauwinkellage verstellt werden.
Der Spinnkonus 19 kann wahlweise, zum Beispiel periodisch in vorgebbaren Zeitabständen, bei einer Spinnunterbrechung nach dem Zufallsprinzip oder bei jeder Spinnunterbrechung, jeweils um einige Winkelgrade in seiner Lagerung verdreht und dadurch die Beanspruchung des Spinnkonus' 19 durch die aus den Blasluftdüsen 23 austretenden Luftströme bzw. durch die sich um den Kopf des Spinnkonus' schlingenden Randfasern nach und nach auf den gesamten Umfang des Spinnkonuskopfes verteilt werden, was sich sehr positiv auf die Lebensdauer des Spinnkonus' 19 auswirkt.The spinning cone 19 is rotatably supported in the rear housing part 15 of the outer housing of the air spinning device 5 in a bearing arrangement 30, for example a simple clearance fit, and can be fixed magnetically in its respective mounting angle position during the spinning process.
That is, in contrast to known air spinning devices, in which due to a fixed nozzle block and a fixed spinning cone 'always the risk that the spinning cone is permanently worn at exposed points extremely exposed in the inventive air spinning device 5 of the spinning cone 19 with respect to its installation angle position become.
The spinning cone 19 can optionally, for example periodically at predetermined time intervals, in a spin interruption at random or at each spin interruption, each twisted by a few degrees in its storage and thereby the stress of the spinning cone '19 by the air streams from the Blasluftdüsen 23 by the around the head of the spinning cone 'looping edge fibers are gradually distributed over the entire circumference of the spinning cone head, which has a very positive effect on the life of the spinning cone' 19.
