  • the thread storage members capture the thread by means of an applied suction air flow and absorb the thread quantity required in each case. Since comparatively large amounts of thread often have to be temporarily stored, such thread storage members have a comparatively large length.

Üblicherweise werden dabei die einzelnen Arbeitsorgane mittels verschiedener Halterungen an einer Wand eines Gestells der Textilmaschine befestigt. Ein Gestell für eine solche Textilmaschine ist beispielsweise in der DE 10 2006 034 228 A1 beschrieben. Die Montage der Arbeitsstelle bzw. der Textilmaschine am Aufstellort ist dabei mit einem hohen Zeitaufwand verbunden. Ebenso ist die Wartung einzelner Arbeitsorgane mit einem hohen Zeitaufwand verbunden, was zu unerwünschten Stillstandszeiten der Arbeitsstelle oder sogar der Textilmaschine führen kann.Textile machines with a large number of workplaces and workplaces of textile machines with fiber-carrying work organs have become known in the prior art in various designs. Usually, the individual working elements are attached to a wall of a frame of the textile machine by means of various brackets. A frame for such a textile machine is for example in the DE 10 2006 034 228 A1 described. The assembly of the job or the textile machine at the installation site is time-consuming. The maintenance of individual work organs is also time-consuming, which can lead to undesired downtimes of the work station or even the textile machine.

Aus der EP 2 172 409 A2 ist eine Rotorspinnmaschine bekannt, bei der eine Spinneinheit mit einer Offenendspinnvorrichtung als Arbeitsorgan an der Rotorspinnmaschine befestigt ist. Der Spinneinheit nachfolgend sind weitere Arbeitsorgane wie beispielsweise eine Abzugseinrichtung und eine Spulvorrichtung an der Rotorspinnmaschine angeordnet. Nähere Angaben zur Befestigung dieser Arbeitsorgane an der Rotorspinnmaschine werden nicht gemacht.From the EP 2 172 409 A2 a rotor spinning machine is known in which a spinning unit with an open-end spinning device is attached to the rotor spinning machine as a working member. Downstream of the spinning unit are further working elements such as, for example, a take-off device and a winding device on the rotor spinning machine. No further details are given on the attachment of these working elements to the rotor spinning machine.

Aus der JP 2009 041153 A ist weiterhin eine Spinnmaschine bekannt, bei der den einzelnen Spinnstellen ein Fasermaterial jeweils über ein langes Gatter bzw. einen Zuführarm zugeführt wird. Der Zuführarm kann schwenkbar an der Textilmaschine angeordnet sein. Zur Montage und Befestigung der einzelnen Arbeitsorgane der Spinnstelle an der Spinnmaschine wird in der Schrift nichts gesagt.From the JP 2009 041153 A a spinning machine is also known in which a fiber material is fed to the individual spinning stations in each case via a long creel or a feed arm. The feed arm can be pivoted on the textile machine. Nothing is said in the document regarding the assembly and fastening of the individual working elements of the spinning station on the spinning machine.

Aus der WO 2012/068693 A1 ist eine Spinnmaschine bekannt, bei der den einzelnen Spinnstellen eine Streckwerkseinheit zugeordnet ist. Die Streckwerkseinheit weist in üblicher Weise mehrere Walzenpaare auf, deren obere Walzen bzw. Druckwalzen an einem schwenkbar gelagerten Druckarm angeordnet sind. Die Unterwalzen sind hingegen fest an der Spinnmaschine angeordnet. Zur Befestigung der Unterwalzen und weiterer Arbeitsorgane an der Spinnmaschine werden ebenfalls keine näheren Angaben gemacht.From the WO 2012/068693 A1 A spinning machine is known in which a drafting unit is assigned to the individual spinning stations. The drafting unit usually has a plurality of pairs of rollers, the upper rollers or pressure rollers of which are arranged on a pivotably mounted pressure arm. The lower rollers, however, are fixed to the spinning machine. No further details are given for fastening the lower rollers and other working elements to the spinning machine.

Aus der JP 2004 107830 A ist eine andere Ausführung einer Spinnmaschine bekannt, bei der den einzelnen Arbeitsstellen jeweils ein Streckwerk vorgeschaltet ist. Am Streckwerksausgang ist eine Verdichtungseinrichtung mit einer besaugten Siebtrommel angeordnet. Die Siebtrommel ist an ein Saugrohr angeschlossen. Das Saugrohr kann auch zwei- oder mehrteilig ausgeführt sein, wobei die Teile des Saugrohres an verschiedenen Haltern gehalten sein können, die ihrerseits fest an der Spinnmaschine angeordnet sind. Ebenso sind pneumatische Fadenspeicherorgane für Textilmaschinen bekannt. Diese werden sowohl bei Spinnmaschinen wie Rotor-, Ring-, oder Luftspinnmaschinen eingesetzt als auch bei weiteren Textilmaschinen wie Spulmaschinen, um verschiedene Arbeits- oder Wartungsvorgänge vornehmen zu können, bei welchen ein Faden gehalten oder zwischengespeichert werden muss. Beispielsweise können derartige pneumatische Fadenspeicherorgane eingesetzt werden, um während des Arbeitsprozesses der Textilmaschine die Fadenspannung konstant zu halten oder im Anspinnprozess bei Rotorspinnmaschinen, um während der Manipulation mit verschiedenen Anspinnorganen jeweils eine benötigte Fadenlänge bereitzuhalten und freigeben zu können. Die Fadenspeicherorgane erfassen den Faden durch einen angelegten Saugluftstrom und nehmen die jeweils benötigte Fadenmenge in sich auf. Da oftmals vergleichsweise große Fadenmengen zwischengespeichert werden müssen, weisen derartige Fadenspeicherorgane eine vergleichsweise große Länge auf. Die Montage der Arbeitsstellen der Textilmaschine mit den Fadenspeicherorganen ist daher oftmals aufwändig.From the JP 2004 107830 A Another embodiment of a spinning machine is known in which a drafting system is connected upstream of the individual work stations. A compacting device with a suctioned screen drum is arranged at the drafting system outlet. The sieve drum is connected to a suction pipe. The suction tube can also be made in two or more parts, wherein the parts of the suction tube can be held on different holders, which in turn are fixedly arranged on the spinning machine. Pneumatic thread storage members for textile machines are also known. These are used in spinning machines such as rotor, ring or air spinning machines as well as in other textile machines such as winding machines, in order to be able to carry out various work or maintenance processes in which a thread has to be held or temporarily stored. For example, such pneumatic thread storage members can be used to keep the thread tension constant during the working process of the textile machine or in the piecing process with rotor spinning machines, in order to hold and release a required thread length during the manipulation with different piecing members to be able to. The thread storage members capture the thread by means of an applied suction air flow and absorb the thread quantity required in each case. Since comparatively large amounts of thread often have to be temporarily stored, such thread storage members have a comparatively large length. The assembly of the workstations of the textile machine with the thread storage elements is therefore often complex.

Um eine kürzere Baulänge zu erreichen, sind Fadenspeicherorgane bekannt geworden, welche eine Fadenspeicherkammer beinhalten, in der der Faden in mehreren nebeneinanderliegenden Schleifen auf einer Siebfläche abgelegt wird. Ein solches Fadenspeicherorgan ist beispielsweise in der DE 38 25 327 C2 gezeigt. Nachteilig bei derartigen Fadenspeichervorrichtungen ist es jedoch, dass es zu Verhakungen der einzelnen nebeneinanderliegenden Fadenschleifen kommen kann, so dass die gespeicherte Fadenmenge nicht schnell genug wieder freigegeben werden kann, wenn dies erforderlich ist. Zudem weisen derartige Fadenspeicherorgane einen vergleichsweise komplexen Aufbau auf und erfordern somit ebenfalls einen hohen Montageaufwand an der Textilmaschine. Daneben kann auch die Reinigung der Fadenspeicherorgane erschwert sein.In order to achieve a shorter overall length, thread storage members have become known which contain a thread storage chamber in which the thread is deposited in several adjacent loops on a sieve surface. Such a thread storage member is for example in the DE 38 25 327 C2 shown. A disadvantage of such thread storage devices is, however, that the individual thread loops lying next to one another can become caught, so that the stored thread quantity cannot be released again quickly enough if this is necessary. In addition, such thread storage members have a comparatively complex structure and thus also require a high amount of assembly work on the textile machine. In addition, the cleaning of the thread storage organs can be difficult.

Aufgabe der vorliegenden Erfindung ist es daher, eine Arbeitsstelle einer Textilmaschine sowie ein pneumatisches Fadenspeicherorgan vorzuschlagen, welche die Montage und die Wartung der Arbeitsstelle vereinfachen. Weiterhin soll eine entsprechende Textilmaschine vorgeschlagen werden.The object of the present invention is therefore to propose a work station of a textile machine and a pneumatic thread storage member, which simplify the assembly and maintenance of the work station. A corresponding textile machine is also to be proposed.

Die Aufgabe wird gelöst mit den Merkmalen des unabhängigen Anspruchs. Eine Arbeitsstelle einer Textilmaschine, insbesondere eine Spinnstelle einer Spinnmaschine, weist eine Vielzahl von faserführenden Arbeitsorganen auf. Unter faserführenden Arbeitsorganen werden dabei im Rahmen der vorliegenden Anmeldung sämtliche Arbeitsorgane verstanden, welche in irgendeiner Form Fasern in Form von Fasermaterial oder in Form eines bereits produzierten Fadens handhaben. Bei einer Spinnmaschine können dies beispielsweise eine Speisewalze, eine Auflösevorrichtung, ein Spinnelement, eine Abzugsvorrichtung, eine Paraffiniereinrichtung, eine Garnüberwachungseinrichtung mit einem Fadenwächter und/oder einer Garnreinigungsvorrichtung, ein Fadenspannungsausgleichsbügel, eine Spulwalze oder auch ein Fadenspeicherorgan sein. Dabei ist es nicht unbedingt erforderlich, dass die hier als faserführende Arbeitsorgane bezeichneten Arbeitsorgane den Faden bzw. die Fasern auch tatsächlich berühren.The object is achieved with the features of the independent claim. A work station of a textile machine, in particular a spinning station of a spinning machine, has a large number of fiber-carrying work members. In the context of the present application, fiber-carrying work organs are understood to mean all work organs which in some form have fibers in the form of fiber material or in the form of one already produced Handle the thread. In the case of a spinning machine, this can be, for example, a feed roller, a dissolving device, a spinning element, a take-off device, a paraffinizing device, a yarn monitoring device with a thread monitor and / or a thread cleaning device, a thread tension compensation bracket, a winding roller or a thread storage element. It is not absolutely necessary that the work organs referred to here as fiber-carrying work organs actually touch the thread or the fibers.

Die Vielzahl von faserführenden Arbeitsorganen ist nun in wenigstens zwei Gruppen unterteilt und die Arbeitsstelle weist wenigstens einen ersten Arbeitsstellenteil auf, an welchem eine erste Gruppe der faserführenden Arbeitsorgane angeordnet ist, und wenigstens einen zweiten Arbeitsstellenteil, an welchem eine zweite Gruppe der faserführenden Arbeitsorgane angeordnet ist. Der zweite Arbeitsstellenteil ist dabei relativ zu dem ersten Arbeitsstellenteil bewegbar, insbesondere verschwenkbar, an der Arbeitsstelle angeordnet und/oder der zweite Arbeitsstellenteil ist abnehmbar an der Arbeitsstelle angeordnet.The plurality of fiber-carrying work elements is now divided into at least two groups and the work station has at least a first work part, on which a first group of the fiber-carrying work elements is arranged, and at least a second work part, on which a second group of the fiber-carrying work elements is arranged. The second work part is movable relative to the first work part, in particular pivotable, arranged at the work place and / or the second work part is removably arranged at the work place.

Durch die Unterteilung der Arbeitsorgane in wenigstens zwei Gruppen wird in besonders günstiger Weise eine umfangreiche Vormontage der beiden Arbeitsstellenteile mit den ihnen jeweils zugeordneten Gruppen von faserführenden Arbeitsorganen ermöglicht. Insbesondere der zweite Arbeitsstellenteil kann dabei jeweils, d.h. an jeder Arbeitsstelle der Textilmaschine, im Ganzen an der Textilmaschine, insbesondere an einem Gestell bzw. einem Gestellabschnitt der Textilmaschine, befestigt werden. Die Montage am Aufstellort ist dadurch erleichtert.By dividing the work organs into at least two groups, extensive pre-assembly of the two work station parts with the groups of fiber-carrying work organs assigned to them is made possible in a particularly advantageous manner. In particular, the second part of the job can, i.e. at each work station of the textile machine, as a whole on the textile machine, in particular on a frame or a frame section of the textile machine. This makes assembly at the installation site easier.

Nach der ersten Ausführung der Erfindung ist dabei der zweite Arbeitsstellenteil verschwenkbar gegenüber dem ersten Arbeitsstellenteil angeordnet. Durch eine solche Ausführung wird nicht nur die Montage der Arbeitsorgane der Arbeitsstelle erleichtert, sondern es ist auch in einfacher Weise eine Reinigung und Wartung der Arbeitsstelle, insbesondere der hinter dem zweiten Arbeitsstellenteil angeordneten Arbeitsorgane und sonstigen Bauteile der Textilmaschine, nach Verschwenken des zweiten Arbeitsstellenteils möglich. Alternativ zu einem Verschwenken des zweiten Arbeitsstellenteils gegenüber dem ersten Arbeitsstellenteil ist es natürlich auch denkbar, den zweiten Arbeitsstellenteil linear beweglich an dem ersten Arbeitsstellenteil anzuordnen.According to the first embodiment of the invention, the second work part is arranged pivotably with respect to the first work part. Such a design not only facilitates the assembly of the work organs of the job, but it is also easy to clean and maintenance of the job, in particular the work organs and other components of the textile machine arranged behind the second job part, is possible after swiveling the second work part. As an alternative to pivoting the second work part relative to the first work part, it is of course also conceivable to arrange the second work part in a linearly movable manner on the first work part.

Alternativ oder zusätzlich ist der zweite Arbeitsstellenteil abnehmbar an der Arbeitsstelle angeordnet. Unter dem Begriff "abnehmbar" wird dabei eine Ausführung verstanden, die ein einfaches und schnelles Lösen des zweiten Arbeitsstellenteils ermöglicht. Dies ermöglicht es, im Falle eines Defekts eines Arbeitsorgans oder eines Bauteils, den gesamten zweiten Arbeitsstellenteil durch einen neuen zu ersetzen, wodurch die Produktion unmittelbar nach dem Austausch wieder aufgenommen werden kann. Der entnommene zweite Arbeitsstellenteil kann dann in Ruhe instandgesetzt werden und später an einer anderen Arbeitsstelle wieder angebracht werden, was vorzugsweise durch ein einfaches Einhängen möglich ist.As an alternative or in addition, the second part of the work station is removably arranged at the work station. The term “removable” is understood to mean an embodiment that enables the second work part to be released easily and quickly. In the event of a defect in a work organ or a component, this makes it possible to replace the entire second work part with a new one, which means that production can be restarted immediately after the replacement. The removed second part of the work station can then be repaired in peace and can later be reattached to another work station, which is preferably possible by simply hanging it up.

Vorzugsweise ist dabei der zweite Arbeitsstellenteil ohne Werkzeug lösbar an der Arbeitsstelle angeordnet. Es ist jedoch ebenso möglich, den zweiten Arbeitsstellenteil vorzugsweise mittels nur eines einzigen Befestigungselements, beispielsweise einer Schraube, an der Arbeitsstelle zu fixieren, um unerwünschte Bewegungen beispielsweise durch Schwingungen der Bauteile und dgl. zu vermeiden.The second part of the work station is preferably arranged detachably at the work station without tools. However, it is also possible to fix the second part of the work station to the work place, preferably by means of only a single fastening element, for example a screw, in order to avoid undesired movements, for example due to vibrations of the components and the like.

Der erste Arbeitsstellenteil kann dabei entweder direkt durch das Gestell bzw. einen Gestellabschnitt der Textilmaschine gebildet sein, wobei die Arbeitsorgane der ersten Gruppe dann direkt, ggf. mittels geeigneter Halterungen, an dem Gestellabschnitt befestigt werden.The first part of the work station can either be formed directly by the frame or a frame section of the textile machine, the work members of the first group then being fastened directly to the frame section, if necessary by means of suitable brackets.

Ebenso ist es jedoch auch möglich, den ersten Arbeitsstellenteil ebenfalls als eine vormontierbare Einheit auszuführen, die im Ganzen an der Arbeitsstelle der Textilmaschine, insbesondere an einem Gestell bzw. einem Gestellabschnitt der Textilmaschine, befestigt werden kann. Es müssen somit zur Montage der Arbeitsstelle an der Textilmaschine nur noch der erste Arbeitsstellenteil und der zweite Arbeitsstellenteil entweder miteinander oder unabhängig voneinander an der Textilmaschine befestigt werden.However, it is also possible to also design the first part of the work station as a preassembled unit, as a whole at the work station the textile machine, in particular on a frame or a frame section of the textile machine, can be attached. Thus, only the first part of the workstation and the second part of the workstation have to be attached to the textile machine either with one another or independently of one another in order to mount the workstation on the textile machine.

Insbesondere wenn auch der erste Arbeitsstellenteil eine vormontierbare Einheit ausbildet, ist es daher auch vorteilhaft, wenn der zweite Arbeitsstellenteil schwenkbar, insbesondere nach oben schwenkbar, an dem ersten Arbeitsstellenteil angeordnet ist. Durch die nach oben schwenkbare Ausführung wird einem Bediener oder Monteur der Zugang zu den hinter oder unter dem zweiten Arbeitsstellenteil angeordneten Arbeitsorganen und Bauteilen der Textilmaschine erleichtert. Je nach Anordnung der Arbeitsorgane an der einzelnen Arbeitsstelle kann jedoch auch ein Schwenken nach unten vorteilhaft sein.In particular, if the first working part also forms a preassembled unit, it is therefore also advantageous if the second working part is arranged on the first working part so that it can be pivoted, in particular pivoted upward. The design, which can be pivoted upwards, makes it easier for an operator or fitter to access the work organs and components of the textile machine arranged behind or under the second work part. Depending on the arrangement of the work organs at the individual work station, however, pivoting downwards can also be advantageous.

Vorteilhaft ist es, wenn eine Spulwalze mittels einer Halterung an dem ersten Arbeitsstellenteil angeordnet ist und der zweite Arbeitsstellenteil schwenkbar, insbesondere um eine Drehachse der Spulwalze schwenkbar, an der Halterung angeordnet ist. Es ist somit kein gesondertes Bauteil für die Aufnahme des zweiten Arbeitsstellenteils erforderlich. Die Spulwalze ist mittels ihrer Halterung beabstandet von einem Gestell der Textilmaschine angeordnet, so dass deren Drehachse vorteilhaft zugleich als Schwenkachse des zweiten Arbeitsstellenteils dienen kann.It is advantageous if a winding roller is arranged on the first working part by means of a holder and the second working part is pivotably arranged on the holder, in particular pivotable about an axis of rotation of the winding roller. There is therefore no need for a separate component for accommodating the second work part. The winding roller is arranged at a distance from a frame of the textile machine by means of its holder, so that its axis of rotation can advantageously also serve as a pivot axis of the second work part.

Nach einer vorteilhaften Weiterbildung der Erfindung beinhaltet der erste Arbeitsstellenteil ein erstes Trägerelement, an welchem zumindest ein Teil der faserführenden Arbeitsorgane der ersten Gruppe angeordnet ist. Die Vormontage und auch die Wartung des ersten Arbeitsstellenteils wird dadurch erleichtert, da auch der erste Arbeitsstellenteil dadurch im Ganzen montierbar bzw. demontierbar ist. Es ist aber auch möglich, dass der erste Arbeitsstellenteil mehrere erste Trägerelemente aufweist, an denen jeweils ein Teil der Arbeitsorgane der ersten Gruppe angeordnet ist und die jeweils separat an der Arbeitsstelle befestigt werden können.According to an advantageous development of the invention, the first part of the work station includes a first carrier element, on which at least part of the fiber-carrying work members of the first group is arranged. The pre-assembly and also the maintenance of the first work part is facilitated because the first work part can be assembled or disassembled as a whole. However, it is also possible for the first work part to have a plurality of first support elements, each of which has a part the work organs of the first group is arranged and each can be attached separately to the work site.

Ebenso ist es vorteilhaft, wenn der zweite Arbeitsstellenteil ein Trägerelement beinhaltet, an dem die faserführenden Arbeitsorgane der zweiten Gruppe angeordnet sind. Hierdurch wird nicht nur die Vormontage, Montage und Demontage des zweiten Arbeitsstellenteils erleichtert, sondern es können auch einzelne Arbeitsorgane besonders leicht ausgetauscht werden. Es ist jedoch auch möglich, dass die einzelnen Arbeitsorgane ohne ein gemeinsames Trägerelement direkt aneinander befestigt werden, um den zweiten Arbeitsstellenteil zu bilden.It is also advantageous if the second work part includes a support element on which the fiber-carrying work members of the second group are arranged. This not only facilitates the pre-assembly, assembly and disassembly of the second part of the work area, but also individual work elements can be exchanged particularly easily. However, it is also possible for the individual working members to be fastened directly to one another without a common carrier element in order to form the second working part.

Ist die Kreuzspulen herstellende Textilmaschine als Spinnmaschine ausgebildet, so weist diese neben einer Vielzahl von faserführenden Arbeitsorganen auch eine Vielzahl von fadenproduzierenden Arbeitsorganen auf. Unter den fadenproduzierenden Arbeitsorganen werden dabei vorwiegend die Arbeitsorgane verstanden, welche in einer sogenannten Spinnbox zusammengefasst sind. Im Falle einer Rotorspinnmaschine umfassen diese beispielsweise den Spinnrotor, die Abzugsdüse, gegebenenfalls ein Drallstauelement und ein Abzugsröhrchen sowie eine Auflöse- und eine Speiseeinheit. Analog dazu umfassen die fadenproduzierenden Arbeitsorgane beispielsweise an einer Luftspinnmaschine eine Luftspinndüse sowie gegebenenfalls nachgeordnete Drallorgane und Abzugsröhrchen. Dabei ist es wiederum vorteilhaft, wenn sämtliche fadenproduzierende Organe an dem ersten Arbeitsstellenteil angeordnet sind. Es können somit die fadenproduzierenden Arbeitsorgane an dem ersten Arbeitsstellenteil vormontiert und ggf. auch gemeinsam aus der Textilmaschine entnommen werden, um diese zu warten oder auszutauschen. Die meisten der faserführenden Arbeitsorgane sind hingegen an dem zweiten Arbeitsstellenteil vormontiert und können daher ebenfalls in einfacher Weise gemeinsam an der Textilmaschine montiert oder zu Wartungs- oder Reinigungszwecken demontiert werden.If the textile machine producing cross-wound bobbins is designed as a spinning machine, it has, in addition to a large number of fiber-carrying working elements, also a large number of thread-producing working elements. The thread-producing work organs are primarily understood to mean the work organs which are combined in a so-called spinning box. In the case of a rotor spinning machine, these include, for example, the spinning rotor, the draw-off nozzle, optionally a swirl stowage element and a draw-off tube as well as a dissolving and a feed unit. Analogously to this, the thread-producing working members comprise, for example on an air spinning machine, an air spinning nozzle and, if appropriate, downstream twisting members and draw-off tubes. It is again advantageous if all the thread-producing organs are arranged on the first part of the work station. The thread-producing work elements can thus be preassembled on the first work part and, if necessary, also removed together from the textile machine in order to maintain or replace them. By contrast, most of the fiber-carrying working elements are preassembled on the second working part and can therefore also be easily assembled together on the textile machine or disassembled for maintenance or cleaning purposes.

Erfindungsgemäß, weist die Arbeitsstelle ein pneumatisches Fadenspeicherorgan, insbesondere ein Fadenspeicherrohr, zum temporären Aufnehmen eines Fadens auf und das Fadenspeicherorgan weist einen zumindest zweiteiligen Aufbau mit einem ersten Fadenspeicherabschnitt und einem zweiten Fadenspeicherabschnitt auf, welche an einer Trennstelle miteinander verbunden sind. Die Trennstelle des pneumatischen Fadenspeicherorgans ermöglicht es dabei, auch das Fadenspeicherorgan, zumindest den zweiten Fadenspeicherabschnitt, als faserführendes Arbeitsorgan in den Vormontageumfang zumindest des zweiten Arbeitsstellenteils zu integrieren.According to the invention, the work station has a pneumatic thread storage element, in particular a thread storage tube, for temporarily holding a thread and the thread storage element has an at least two-part construction with a first thread storage section and a second thread storage section, which are connected to one another at a separation point. The separation point of the pneumatic thread storage member makes it possible to integrate the thread storage member, at least the second thread storage section, as a fiber-guiding working member in the preassembly scope of at least the second work part.

Dabei ist, erfindungsgemäß, der erste Fadenspeicherabschnitt an dem ersten Arbeitsstellenteil und der zweite Fadenspeicherabschnitt an dem zweiten Arbeitsstellenteil angeordnet. Hierdurch wird in besonders günstiger Weise eine umfangreiche Vormontage der beiden Arbeitsstellenteile mit den ihnen jeweils zugeordneten Fadenspeicherabschnitten ermöglicht, welche dann jeweils im Ganzen an der Textilmaschine, insbesondere an einem Gestell der Textilmaschine, befestigt werden können. Es müssen somit zur Montage der Arbeitsstelle an der Textilmaschine nur noch der erste Arbeitsstellenteil und der zweite Arbeitsstellenteil entweder miteinander oder unabhängig voneinander an der Textilmaschine befestigt werden, wobei zugleich die beiden Fadenspeicherabschnitte an der Trennstelle zu dem Fadenspeicherorgan zusammengesetzt werden.According to the invention, the first thread storage section is arranged on the first work part and the second thread storage section is arranged on the second work part. In this way, extensive pre-assembly of the two workstation parts with the thread storage sections assigned to them is made possible in a particularly favorable manner, which can then be attached to the textile machine as a whole, in particular to a frame of the textile machine. Thus, only the first part of the workstation and the second part of the workstation have to be fastened to one another or independently of one another on the textile machine in order to assemble the workstation on the textile machine, with the two thread storage sections being assembled at the separation point to form the thread storage member.

Ein, nicht beanspruchtes, Fadenspeicherorgan, insbesondere ein Fadenspeicherrohr, für eine Arbeitsstelle einer Textilmaschine, insbesondere eine Spinnstelle einer Spinnmaschine, zum temporären Aufnehmen eines Fadens weist daher einen zumindest zweiteiligen Aufbau auf. Dabei sind ein erster Fadenspeicherabschnitt und ein zweiter Fadenspeicherabschnitt vorgesehen, welche an einer Trennstelle miteinander verbunden sind.A thread storage member, not claimed, in particular a thread storage tube, for a work station of a textile machine, in particular a spinning station of a spinning machine, for temporarily holding a thread therefore has an at least two-part construction. A first thread storage section and a second thread storage section are provided, which are connected to one another at a separation point.

Nach einer ersten Ausführung des Fadenspeicherorgans sind dabei der erste Fadenspeicherabschnitt und der zweite Fadenspeicherabschnitt an der Trennstelle vollständig voneinander lösbar. Die Montage und Demontage des Fadenspeicherorgans bzw. von mit dem betreffenden Fadenspeicherabschnitt verbundenen Arbeitsorganen ist dadurch in besonders einfacher und flexibler Weise möglich. Zugleich wird auch die Reinigung und Wartung des Fadenspeicherorgans erleichtert. So kann beispielsweise der erste Fadenspeicherabschnitt bereits zusammen mit der ersten Gruppe von Arbeitsorganen der Arbeitsstelle vormontiert werden und dann gemeinsam mit diesen als erster Arbeitsstellenteil an der Arbeitsstelle der Textilmaschine, insbesondere an einem Gestellabschnitt der Textilmaschine, angebracht werden kann. Alternativ kann der erste Fadenspeicherabschnitt jedoch auch als einzelnes Bauteil direkt an der Arbeitsstelle angeordnet sein. Der zweite Fadenspeicherabschnitt kann separat von dem ersten Fadenspeicherabschnitt an dem zweiten Arbeitsstellenteil befestigt werden. Wird dann der vormontierte, zweite Arbeitsstellenteil zusammen mit dem bereits daran angebauten zweiten Fadenspeicherabschnitt an das Gestell der Textilmaschine montiert, insbesondere eingehängt, so können dadurch einfacher Weise die beiden Fadenspeicherabschnitte zugleich zu dem Fadenspeicherorgan verbunden werden. Selbstverständlich ist es dabei auch denkbar, dass das Fadenspeicherorgan nicht nur einen ersten und einen zweiten Fadenspeicherabschnitt aufweist, sondern noch weitere Fadenspeicherabschnitte vorgesehen sind. Die Montage des Fadenspeicherorgans kann hierdurch weiter vereinfacht werden, da das Fadenspeicherorgan nicht mehr im Ganzen an der Textilmaschine montiert werden muss. Der zwei- oder mehrteilige Aufbau des Fadenspeicherorgans bietet dabei nicht nur bei der Montage, sondern auch bei der Reinigung und Wartung einen Vorteil, da sämtliche Fadenspeicherabschnitte des Fadenspeicherorgans durch die Trennstelle(n) gut zugänglich sind. Wird der zweite Arbeitsstellenteil im Falle einer abnehmbaren Ausführung von der Arbeitsstelle abgenommen, so werden dadurch ohne Demontagearbeiten zugleich auch die Fadenspeicherabschnitte voneinander getrennt.According to a first embodiment of the thread storage member, the first thread storage section and the second thread storage section can be completely detached from one another at the separation point. The assembly and disassembly of the thread storage member or of the working members connected to the thread storage section in question is thereby possible in a particularly simple and flexible manner. At the same time, the cleaning and maintenance of the thread storage member is facilitated. For example, the first thread storage section can already be preassembled together with the first group of work organs of the work station and can then be attached together with these as the first work part to the work station of the textile machine, in particular to a frame section of the textile machine. Alternatively, however, the first thread storage section can also be arranged as a single component directly at the work station. The second thread storage section can be attached to the second work part separately from the first thread storage section. If the preassembled, second working part is then mounted, in particular hung, together with the second thread storage section already attached to the frame of the textile machine, the two thread storage sections can thereby be connected to the thread storage member in a simple manner. Of course, it is also conceivable that the thread storage member not only has a first and a second thread storage section, but also further thread storage sections are provided. The assembly of the thread storage member can hereby be further simplified since the thread storage member no longer has to be assembled as a whole on the textile machine. The two-part or multi-part structure of the thread storage member offers an advantage not only in assembly but also in cleaning and maintenance, since all thread storage sections of the thread storage member are easily accessible through the separation point (s). If the second part of the work station is removed from the work station in the case of a removable version, the thread storage sections are also separated from one another without dismantling work.

Die Trennstelle muss dabei jedoch nach einer zweiten Ausführungsform des Fadenspeicherorgans keine vollständige Trennung der Fadenspeicherabschnitte ermöglichen. Vielmehr kann es auch ausreichend sein, wenn die beiden Fadenspeicherabschnitte an der Trennstelle relativ zueinander bewegbar miteinander verbunden sind. Beispielsweise können der erste Fadenspeicherabschnitt und der zweite Fadenspeicherabschnitt an der Trennstelle auch schwenkbar miteinander verbunden sein, was im Falle eines schwenkbar angeordneten, zweiten Arbeitsstellenteils vorteilhaft ist. Aufgrund der Bewegbarkeit der beiden Fadenspeicherabschnitte gegeneinander ist es dabei dennoch möglich, das Fadenspeicherorgan bzw. einen Fadenspeicherabschnitt des Fadenspeicherorgans zusammen mit anderen Arbeitsorganen der Arbeitsstelle zu einem Vormontageumfang zusammenzufassen. Der andere Fadenspeicherabschnitt, welcher bewegbar mit dem ersten Fadenspeicherabschnitt verbunden ist, kann dann bei der Montage des Vormontageumfangs an der Textilmaschine in einfacher Weise entweder mit einem Unterdruckkanal der Textilmaschine oder aber mit einem weiteren, an der Textilmaschine angeordneten Abschnitt des Fadenspeicherorgans verbunden werden.
In jedem Fall ermöglicht dabei das beschriebene Fadenspeicherorgan mit dem zweiteiligen Aufbau mit einem ersten Fadenspeicherabschnitt und einem zweiten Fadenspeicherabschnitt eine vereinfachte Montage der Arbeitsstelle der Textilmaschine sowie des Fadenspeicherorgans selbst.
Da bei einer Textilmaschine eine Vielzahl von pneumatischen Fadenspeicherorganen und eine Vielzahl von Arbeitsstellen zu montieren sind, sind das Fadenspeicherorgan und die Arbeitsstelle mit dem zweiteiligen Aufbau in verschiedenen Textilmaschinen vorteilhaft einsetzbar. Es wird daher auch eine Textilmaschine mit einer derartigen Arbeitsstelle beansprucht.According to a second embodiment of the thread storage element, however, the separation point does not have to allow complete separation of the thread storage sections. Rather, it may also be sufficient if the two thread storage sections are connected to one another so as to be movable relative to one another at the separation point. For example, the first thread storage section and the second thread storage section can also be pivotally connected to one another at the separation point, which is advantageous in the case of a pivotably arranged second work part. Because the two thread storage sections can be moved relative to one another, it is nevertheless possible to combine the thread storage member or a thread storage section of the thread storage member together with other working members of the work station to form a preassembly scope. The other thread storage section, which is movably connected to the first thread storage section, can then be connected in a simple manner either to a vacuum duct of the textile machine or else to a further section of the thread storage member arranged on the textile machine when the preassembly scope is mounted on the textile machine.
In any case, the thread storage member described with the two-part construction with a first thread storage section and a second thread storage section enables simplified assembly of the work station of the textile machine and of the thread storage member itself.
Since a large number of pneumatic thread storage members and a large number of work stations are to be installed in a textile machine, the thread storage member and the work station with the two-part construction can be used advantageously in different textile machines. A textile machine with such a job is therefore also claimed.

Um das Zusammensetzen des ersten Fadenspeicherabschnitts und des zweiten Fadenspeicherabschnitts zu dem Fadenspeicherorgan zu ermöglichen, ist es vorteilhaft, wenn einer der beiden Fadenspeicherabschnitte an seinem dem anderen Fadenspeicherabschnitt zugewandten Ende eine Erweiterung aufweist. Hierdurch kann bei der Montage der beiden Arbeitsstellenteile miteinander bzw. an der Textilmaschine in einfacher Weise erreicht werden, dass auch die beiden Fadenspeicherabschnitte sicher zusammengefügt werden. In derselben Weise kann es daher auch vorteilhaft sein, wenn einer der beiden Fadenspeicherabschnitte an seinem dem anderen Fadenspeicherabschnitt zugewandten Ende eine Reduzierung aufweist. Grundsätzlich können die beiden zusammenzufügenden Fadenspeicherabschnitte jedoch auch dieselben Abmessungen an der Trennstelle aufweisen.In order to enable the first thread storage section and the second thread storage section to be combined to form the thread storage member, it is advantageous if one of the two thread storage sections has an extension at its end facing the other thread storage section. In this way, when the two workstation parts are assembled with one another or on the textile machine, the two thread storage sections can be securely joined together. In the same way, it can therefore also be advantageous if one of the two thread storage sections has a reduction at its end facing the other thread storage section. In principle, however, the two thread storage sections to be joined can also have the same dimensions at the separation point.

Weitere Vorteile der Erfindung werden anhand der nachfolgend dargestellten Ausführungsbeispiele beschrieben. Es zeigen:

Bei den nachfolgenden Beschreibungen der Figuren werden für Merkmale, die in ihrer Ausgestaltung und/oder Wirkweise identisch und/oder zumindest vergleichbar sind, gleiche Bezugszeichen verwendet. Aus Gründen der Übersichtlichkeit sind dabei nicht alle Merkmale in allen Figuren dargestellt und bezeichnet.

For reasons of clarity, not all features are shown and labeled in all figures. Likewise, some features are not described in all of the figures, but are only explained by way of example using one of the figures.

Figur 1 zeigt eine Arbeitsstelle 2 einer Textilmaschine 1 in einer schematischen, geschnittenen Seitenansicht. An der Arbeitsstelle 2 sind dabei eine Vielzahl von faserführenden Arbeitsorganen 5, 6, 7, 8, 10, 11, 12, 14, 17, 23, 24 angeordnet, mittels welcher ein Faden 9 gegebenenfalls produziert werden und nach seiner Produktion einer Spulvorrichtung 20 zugeführt werden kann. Figure 1 shows a work station 2 of a textile machine 1 in a schematic, sectional side view. At the work station 2, a large number of fiber-carrying work elements 5, 6, 7, 8, 10, 11, 12, 14, 17, 23, 24 are arranged, by means of which a thread 9 may be produced and fed to a winding device 20 after its production can be.

Die vorliegende Textilmaschine 1 ist dabei als Rotorspinnmaschine ausgebildet, welche eine Vielzahl von Arbeitsstellen 2 in einer Anordnung nebeneinander aufweist. Den Arbeitsstellen 2 wird dabei in an sich bekannter Weise ein Fasermaterial 4 aus einem Vorratsbehälter 3 über eine Zuführeinrichtung 5 zugeführt, die vorliegend eine Speisewalze 6 sowie eine Auflösevorrichtung 7 umfasst. Von dort wird das in seine Einzelfasern aufgelöste Fasermaterial 4 einem Spinnelement 8 zugeführt, das vorliegend als Spinnrotor ausgebildet ist und in welchem das Fasermaterial 4 zu dem Faden 9 versponnen wird. Der produzierte Faden 9 wird dann mittels einer Abzugsvorrichtung 10 abgezogen und über eine Reihe weiterer faserführender Arbeitsorganen 5, 6, 7, 8, 10, 11, 12, 14, 17, 23, 24 der Spulvorrichtung 20 mit der Spulwalze 14 und der Kreuzspule 15 zugeführt, auf welche er mittels einer hier nur schematisch angedeuteten Changiervorrichtung 23 aufgewickelt wird. Die Changiervorrichtung 23 beinhaltet einen hier symbolisch dargestellten Changierfadenführer sowie einen nicht dargestellten Changierantrieb. Vorliegend sind als weitere faserführende Arbeitsorgane die Abzugsvorrichtung 10, eine Garnüberwachungseinrichtung 12, eine Einrichtung zum Fadenspannungsausgleich 13 sowie eine Paraffiniereinrichtung 11 vorgesehen. Ebenso bilden die Zuführeinrichtung 5, die Speisewalze 6, die Auflösevorrichtung 7, das Spinnelement 8, die Spulwalze 14 und die Changiereinrichtung 23 faserführende Arbeitsorgane 5, 6, 7, 8, 10, 11, 12, 14, 17, 23, 24. Diese Aufzählung der faserführenden Arbeitsorgane ist dabei jedoch lediglich beispielhaft zu verstehen. Ebenso könnten zusätzliche faserführende Arbeitsorgane 5, 6, 7, 8, 10, 11, 12, 14, 17, 23, 24oder auch andere faserführende Arbeitsorgane 5, 6, 7, 8, 10, 11, 12, 14, 17, 23, 24vorgesehen sein. Die Garnüberwachungseinrichtung 12 kann dabei ebenfalls unterschiedlich ausgebildet sein und in einfachster Weise lediglich einen Fadenwächter beinhalten oder auch zusätzlich eine Garnreinigungseinrichtung aufweisen.The present textile machine 1 is designed as a rotor spinning machine, which has a plurality of work stations 2 arranged next to one another. The work stations 2 are fed in a manner known per se from a fiber material 4 from a storage container 3 via a feed device 5, which in the present case comprises a feed roller 6 and a dissolving device 7. From there, the fiber material 4 broken down into its individual fibers is fed to a spinning element 8, which in the present case is designed as a spinning rotor and in which the fiber material 4 is spun into the thread 9. The thread 9 produced is then drawn off by means of a take-off device 10 and via a number of further fiber-carrying working elements 5, 6, 7, 8, 10, 11, 12, 14, 17, 23, 24 of the winding device 20 with the winding roller 14 and the cheese 15 are fed, on which it is wound up by means of a traversing device 23, which is only indicated schematically here. The traversing device 23 includes a traversing thread guide symbolically shown here and a traversing drive, not shown. In the present case, the take-off device 10, a yarn monitoring device 12, a device for thread tension compensation 13 and a paraffinizing device 11 are provided as further fiber-carrying working members. Likewise, the feed device 5, the feed roller 6, the opening device 7, the spinning element 8, the winding roller 14 and the traversing device 23 form fiber-carrying working elements 5, 6, 7, 8, 10, 11, 12, 14, 17, 23, 24. These The list of fiber-carrying work organs is only to be understood as an example. Likewise, additional fiber-guiding working elements 5, 6, 7, 8, 10, 11, 12, 14, 17, 23, 24 or other fiber-guiding working elements 5, 6, 7, 8, 10, 11, 12, 14, 17, 23, 24 be provided. The yarn monitoring device 12 can also be designed differently and in the simplest way contain only a yarn monitor or additionally have a yarn cleaning device.

Selbstverständlich ist auch die gezeigte Ausführung der Textilmaschine 1 als Rotorspinnmaschine lediglich beispielhaft zu verstehen. Ebenso könnte die Textilmaschine als Luftspinnmaschine ausgebildet sein, wobei dann die Zuführeinrichtung 5 ein Streckwerk mit Lieferwalzen beinhaltet und das Spinnelement als Luftspinndüse ausgebildet ist. Weiterhin könnte die Textilmaschine auch als Ringspinnmaschine, sonstige Spinnmaschine oder Spulmaschine ausgebildet sein. Der Faden 9 muss daher auch nicht unbedingt auf eine Kreuzspule gewickelt werden, sondern könnte ebenso auf einen Garnkops gewickelt werden.Of course, the shown embodiment of the textile machine 1 as a rotor spinning machine is to be understood only as an example. Likewise, the textile machine could be designed as an air spinning machine, in which case the feed device 5 contains a drafting system with delivery rollers and the spinning element is designed as an air spinning nozzle. Furthermore, the textile machine could also be designed as a ring spinning machine, other spinning machine or winding machine. The thread 9 therefore does not necessarily have to be wound on a cheese, but could also be wound on a yarn bobbin.

Weiterhin ist an der vorliegend dargestellten Textilmaschine 1 ein Unterdruckkanal 16 zu erkennen, welcher sich in Längsrichtung der Textilmaschine 1 entlang der Arbeitsstellen 2 erstreckt und an welchen die einzelnen Arbeitsstellen 2 der Textilmaschine 1 angeschlossen sind. Vorliegend wird durch den Unterdruckkanal 16 auch der Spinnunterdruck, welcher für das Rotorspinnen benötigt wird, bereitgestellt. Bei anderen Arten von Spinnmaschinen und Textilmaschinen 1 wird für den Spinnprozess selbst bzw. den Arbeitsprozess selbst kein Unterdruck benötigt. Es sind jedoch in der Regel mehrere Arbeitsorgane an den Arbeitsstellen 2 von Textilmaschinen 1 vorhanden, welche Unterdruck benötigen.Furthermore, a vacuum channel 16 can be seen in the textile machine 1 shown here, which extends in the longitudinal direction of the textile machine 1 along the work stations 2 and at which the individual work stations 2 of the textile machine 1 are connected. In the present case, the vacuum negative pressure which is required for rotor spinning is also provided by the vacuum channel 16. In other types of spinning machines and textile machines 1, no negative pressure is required for the spinning process itself or the working process itself. However, there are usually several work organs at the work stations 2 of textile machines 1 which require negative pressure.

Die Arbeitsstelle 2 weist einen zweiteiligen Aufbau mit einem ersten Arbeitsstellenteil 2a und einem zweiten Arbeitsstellenteil 2b auf. Es ergibt sich hierdurch eine besonders vorteilhafte Bauweise einer Arbeitsstelle 2, welche eine Vormontage von faserführenden Arbeitsorganen 5, 6, 7, 8, 10, 11, 12, 14, 17, 23, 24 an dem ersten Arbeitsstellenteil 2a und an dem zweiten Arbeitsstellenteil 2b ermöglicht. Die faserführenden Arbeitsorgane 5, 6, 7, 8, 10, 11, 12, 14, 17, 23, 24 sind hierzu in wenigstens zwei Gruppen unterteilt. Die beiden Arbeitsstellenteile 2a und 2b können daher in besonders günstiger Weise nahezu vollständig vormontiert werden und als Vormontageumfang in einfacher Weise an einem Gestellabschnitt 21 der Textilmaschine 1, welcher der jeweiligen Arbeitsstelle zugeordnet ist und vorliegend lediglich symbolisch dargestellt ist, befestigt werden.The work station 2 has a two-part construction with a first work part 2a and a second work part 2b. This results in a particularly advantageous construction of a work station 2, which pre-assembles fiber-carrying work members 5, 6, 7, 8, 10, 11, 12, 14, 17, 23, 24 on the first work part 2a and on the second work part 2b enables. For this purpose, the fiber-carrying working elements 5, 6, 7, 8, 10, 11, 12, 14, 17, 23, 24 are divided into at least two groups. The two work station parts 2a and 2b can therefore be almost completely preassembled in a particularly favorable manner and, as a preassembly scope, can be fastened in a simple manner to a frame section 21 of the textile machine 1, which is assigned to the respective work station and is only shown symbolically in the present case.

Vorliegend sind an dem ersten Arbeitsstellenteil 2a als faserführende Arbeitsorgane 5, 6, 7, 8, 10, 11, 12, 14, 17, 23, 24 insbesondere fadenproduzierende Arbeitsorgane wie im vorliegenden Fall einer Rotorspinnmaschine die Auflösewalze 7, die Speisewalze 6, das Spinnelement 8 sowie ggf. weitere, hier nicht dargestellte fadenproduzierende Arbeitsorgane angeordnet. Außerdem ist die Spulwalze 14 vorliegend an dem ersten Arbeitsstellenteil 2a angeordnet. Die genannten Arbeitsorgane bilden gemeinsam die erste Gruppe der faserführenden Arbeitsorgane 5, 6, 7, 8, 10, 11, 12, 14, 17, 23, 24. An dem zweiten Arbeitsstellenteil 2b sind hingegen sämtliche faserführenden Arbeitsorgane 5, 6, 7, 8, 10, 11, 12, 14, 17, 23, 24 angeordnet, welche den fadenproduzierenden Arbeitsorganen folgen, hier also insbesondere die Abzugsvorrichtung 10, zumindest ein Teil des Fadenspeicherorgans 17, die Garnüberwachungseinrichtung 12, die Paraffiniereinrichtung 11 sowie die Changiereinrichtung 23. Diese bilden gemeinsam die zweite Gruppe der faserführenden Arbeitsorgane 5, 6, 7, 8, 10, 11, 12, 14, 17, 23, 24. Natürlich ist auch dies lediglich beispielhaft zu verstehen, es können dabei auch noch weitere oder andere faserführende Arbeitsorgane 5, 6, 7, 8, 10, 11, 12, 14, 17, 23, 24 vorgesehen sein, beispielsweise eine an der Arbeitsstelle angeordnete Saugdüse 24 (s. Fig. 2 und 5).In the present case, the opening roller 7, the feed roller 7, the feed roller 6, and the spinning element are in particular fiber-producing working elements 5, 6, 7, 8, 10, 11, 12, 14, 17, 23, 24 on the first part of the work station, as in the present case of a rotor spinning machine 8 and, if appropriate, further thread-producing working elements, not shown here, are arranged. In addition, the winding roller 14 is arranged in the present case on the first work part 2a. The above-mentioned work organs jointly form the first group of fiber-guiding work organs 5, 6, 7, 8, 10, 11, 12, 14, 17, 23, 24. On the other hand, all fiber-guiding work organs 5, 6, 7, 8 are on the second work part 2b , 10, 11, 12, 14, 17, 23, 24 arranged, which follow the thread-producing work organs, here in particular the take-off device 10, at least part of the thread storage member 17, the yarn monitoring device 12, the paraffinizing device 11 and the traversing device 23. These together form the second group of fiber-carrying working members 5, 6, 7, 8, 10, 11, 12, 14, 17, 23, 24. Of course, this is also to be understood only as an example; further or other fiber-carrying working elements 5, 6, 7, 8, 10, 11, 12, 14, 17, 23, 24 can also be provided, for example one the suction nozzle 24 (see. Fig. 2 and 5 ).

Der erste Arbeitsstellenteil 2a beinhaltet vorliegend ein erstes Trägerelement 27, an welchem die erste Gruppe der faserführenden Arbeitsorgane 5, 6, 7, 8, 10, 11, 12, 14, 17, 23, 24 angeordnet ist. Der zweite Arbeitsstellenteil 2b beinhaltet vorliegend ein zweites Trägerelement 28 für die zweite Gruppe der faserführenden Arbeitsorgane 5, 6, 7, 8, 10, 11, 12, 14, 17, 23, 24, welche dadurch in besonders vorteilhafter Weise in korrekter Positionierung zueinander an diesem vormontiert werden können. Dabei ist der zweite Arbeitsstellenteil 2b vorliegend schwenkbar an dem ersten Arbeitsstellenteil 2a angeordnet und kann daher einfacher Weise zu Montage- und Reinigungszwecken weggeschwenkt werden.The first work station part 2a in the present case contains a first carrier element 27, on which the first group of fiber-carrying work members 5, 6, 7, 8, 10, 11, 12, 14, 17, 23, 24 is arranged. The second work part 2b in the present case contains a second carrier element 28 for the second group of fiber-guiding work elements 5, 6, 7, 8, 10, 11, 12, 14, 17, 23, 24, which in a particularly advantageous manner thereby results in correct positioning with respect to one another can be pre-assembled. In the present case, the second work part 2b is pivotably arranged on the first work part 2a and can therefore be pivoted away in a simple manner for assembly and cleaning purposes.

Vorliegend ist dabei der zweite Arbeitsstellenteil 2b schwenkbar um eine Schwenkachse 29 an einer Halterung 25 angeordnet, an welcher zugleich auch die Spulwalze 14 gelagert ist. Dabei ist vorliegend der zweite Arbeitsstellenteil 2b um die Drehachse 26 der Spulwalze 14 schwenkbar, so dass die Drehachse 26 und die Schwenkachse 29 identisch sind. Natürlich können die Drehachse 26 und die Schwenkachse 29 auch räumlich getrennt voneinander vorgesehen sein.In the present case, the second working part 2b is arranged pivotably about a pivot axis 29 on a holder 25, on which the winding roller 14 is also mounted. In the present case, the second working part 2b is pivotable about the axis of rotation 26 of the winding roller 14, so that the axis of rotation 26 and the axis of pivot 29 are identical. Of course, the axis of rotation 26 and the pivot axis 29 can also be provided spatially separated from one another.

Weiterhin weist die Arbeitsstelle 2 ein pneumatisches Fadenspeicherorgan 17 auf, mittels welchem in an sich bekannter Weise ein Faden für verschiedene Arbeitsschritte fixiert werden kann sowie eine bestimmte Fadenmenge zwischengespeichert werden kann. Auch dieses bildet ein faserführendes Arbeitsorgan 5, 6, 7, 8, 10, 11, 12, 14, 17, 23, 24. Das schlaufenförmige Einsaugen eines Fadenstücks in das Fadenspeicherorgan 17 ist vorliegend mit einer gestrichelten Linie angedeutet. Beispielsweise kann mittels derartiger pneumatischer Fadenspeicherorgane 17 die Fadenspannung bei bestimmten Arbeitsschritten konstant gehalten werden oder es kann beispielsweise eine bestimmte Fadenlänge zwischengespeichert werden, welche beim Anspinnprozess wieder freigegeben werden muss. Vorliegend ist das Fadenspeicherorgan 17 als Fadenspeicherrohr ausgebildet. Da oftmals vergleichsweise große Fadenmengen zwischengespeichert werden müssen, die schnell und zuverlässig wieder freigegeben werden müssen, weisen derartige Fadenspeicherorgane 17 oftmals vergleichsweise große Abmessungen auf, was deren Einbau in der Textilmaschine 1 sowie die Montage der verschiedenen Arbeitsorgane an der Arbeitsstelle 2 erschwert. Ebenso ist die Zugänglichkeit des Fadenspeicherorgans 17 zu Reinigungszwecken dadurch oftmals erschwert. Das Fadenspeicherorgan 17 weist einen zweiteiligen Aufbau mit einem ersten Fadenspeicherabschnitt 17a und einem zweiten Fadenspeicherabschnitt 17b auf, welche an einer Trennstelle 18 miteinander verbunden sind, wie im Folgenden noch näher erläutert werden wird.Furthermore, the work station 2 has a pneumatic thread storage member 17, by means of which a thread can be fixed for various work steps in a manner known per se and a certain amount of thread can be stored temporarily. This also forms a fiber Working element 5, 6, 7, 8, 10, 11, 12, 14, 17, 23, 24. The loop-shaped sucking of a piece of thread into the thread storage element 17 is indicated here with a dashed line. For example, by means of such pneumatic thread storage members 17, the thread tension can be kept constant in certain work steps or, for example, a certain thread length can be temporarily stored, which must be released again during the piecing process. In the present case, the thread storage member 17 is designed as a thread storage tube. Since comparatively large amounts of thread often have to be temporarily stored, which have to be released quickly and reliably, thread storage members 17 of this type often have comparatively large dimensions, which complicates their installation in the textile machine 1 and the assembly of the various working members at the work station 2. Likewise, the accessibility of the thread storage member 17 for cleaning purposes is often made more difficult. The thread storage member 17 has a two-part construction with a first thread storage section 17a and a second thread storage section 17b, which are connected to one another at a separation point 18, as will be explained in more detail below.

Figur 2 zeigt ähnlich wie die Figur 1 eine schematische Schnittdarstellung einer Arbeitsstelle einer Textilmaschine mit einem ersten Arbeitsstellenteil 2a und einem verschwenkbaren, zweiten Arbeitsstellenteil 2b. Ebenso ist das Fadenspeicherorgan 17 zweiteilig aufgebaut. Dabei ist der erste Fadenspeicherabschnitt 17a an dem ersten Arbeitsstellenteil 2a angeordnet und der zweite Fadenspeicherabschnitt 17b an dem zweiten Arbeitsstellenteil 2b angeordnet. Wird nun der zweite Arbeitsstellenteil 2b von dem ersten Arbeitsstellenteil 2a beispielsweise zu Montage- und Reinigungszwecken weggeschwenkt, so wird dabei das pneumatische Fadenspeicherorgan 17 an der Trennstelle 18 getrennt. Im Unterschied zur Figur 1 weist vorliegend die Arbeitsstelle 2 noch eine an der Arbeitsstelle 2, vorliegend an dem zweiten Arbeitsstellenteil 2b, stationär angeordnete Saugdüse 24 auf. Die Saugdüse 24 gehört somit vorliegend zur zweiten Gruppe von faserführenden Arbeitsorganen 5, 6, 7, 8, 10, 11, 12, 14, 17, 23, 24. Figure 2 shows similar to that Figure 1 is a schematic sectional view of a work station of a textile machine with a first work part 2a and a pivotable, second work part 2b. The thread storage member 17 is also constructed in two parts. The first thread storage section 17a is arranged on the first work part 2a and the second thread storage section 17b is arranged on the second work part 2b. If the second working part 2b is now pivoted away from the first working part 2a, for example for assembly and cleaning purposes, then the pneumatic thread storage member 17 is separated at the separation point 18. In contrast to Figure 1 In the present case, the work station 2 also has a suction nozzle 24 arranged stationarily at the work station 2, in the present case at the second work part 2b. The suction nozzle 24 belongs here to the second group of fiber-carrying working elements 5, 6, 7, 8, 10, 11, 12, 14, 17, 23, 24.

Durch die Ausbildung des Fadenspeicherorgans 17 mit einem ersten Fadenspeicherabschnitt 17a und einem zweiten Fadenspeicherabschnitt 17b wird dabei dennoch in einfacher Weise ein zusammenhängendes Fadenspeicherorgan 17 erreicht. Dabei wird bei Montage des zweiten Arbeitsstellenteils 2b an dem Gestellabschnitt 21 der Textilmaschine 1 bzw. gegebenenfalls an dem ersten Arbeitsstellenteil 2a der zweite Fadenspeicherabschnitt 17b auch automatisch korrekt in Bezug auf den ersten Fadenspeicherabschnitt 17a positioniert.By forming the thread storage member 17 with a first thread storage section 17a and a second thread storage section 17b, a coherent thread storage member 17 is nevertheless achieved in a simple manner. When the second work part 2b is mounted on the frame section 21 of the textile machine 1 or possibly on the first work part 2a, the second thread storage section 17b is also automatically correctly positioned with respect to the first thread storage section 17a.

In der Figur 2 ist weiterhin dargestellt, dass nach einer vorteilhaften Ausführung der Arbeitsstelle 2 der zweite Arbeitsstellenteil 2b nicht nur schwenkbar, sondern auch abnehmbar an der Arbeitsstelle 2 angeordnet sein kann. Das Trägerelement 28 oder, wenn kein gemeinsames Trägerelement 28 vorhanden ist, ein sonstiger Halter des Arbeitsstellenteils 2b, kann hierzu wie vorliegend gezeigt lediglich in die Halterung 25 eingeschoben werden und ggf. mittels eines hier nicht dargestellten Befestigungselements an der Arbeitsstelle fixiert werden. Ebenso könnte das Trägerelement 28 oder ein sonstiger Halter eine hakenförmige Aufhängelasche oder dgl. (nicht gezeigt) aufweisen, mittels welcher es an der Arbeitsstelle 2 eingehängt werden kann.In the Figure 2 it is further shown that, according to an advantageous embodiment of the work station 2, the second work station part 2 b can be arranged not only pivotably, but also removably at the work station 2. The support element 28 or, if there is no common support element 28, another holder of the workstation part 2b, can only be inserted into the holder 25 for this purpose as shown here and, if necessary, be fixed to the workstation by means of a fastening element, not shown here. Likewise, the carrier element 28 or another holder could have a hook-shaped hanging tab or the like (not shown), by means of which it can be hung on the work station 2.

Um das Zusammenfügen der beiden Fadenspeicherabschnitte 17 a, 17b an der Trennstelle 18 zu erleichtern, ist es vorteilhaft, wenn zumindest einer der beiden Fadenspeicherabschnitte 17a, 17b an seinem dem anderen Fadenspeicherabschnitt 17a, 17b zugewandten Ende eine Erweiterung 19 aufweist. Dies ist in Figur 3 dargestellt. Vorliegend weist der Fadenspeicherabschnitt 17b an seinem dem Fadenspeicherabschnitt 17a zugewandten Ende eine trichterförmige Erweiterung 19 auf. Hierdurch wird sichergestellt, dass trotz der Schwenkbewegung die beiden Fadenspeicherabschnitte 17a, 17b zuverlässig zusammengeführt werden können. Alternativ oder zusätzlich wäre es natürlich auch möglich, dass der andere Fadenspeicherabschnitt, in diesem Fall der Fadenspeicherabschnitt 17a, an seinem dem Fadenspeicherabschnitt 17b zugewandten Ende eine entsprechende Reduzierung 22 (s. auch Fig. 4) aufweist. Selbstverständlich könnte dabei die Reduzierung 22 oder die Erweiterung 19 auch an dem jeweils anderen Fadenspeicherabschnitt 17a, 17b angeordnet sein.In order to facilitate the joining of the two thread storage sections 17 a, 17b at the separation point 18, it is advantageous if at least one of the two thread storage sections 17a, 17b has an extension 19 at its end facing the other thread storage section 17a, 17b. This is in Figure 3 shown. In the present case, the thread storage section 17b has a funnel-shaped extension 19 at its end facing the thread storage section 17a. This ensures that, despite the pivoting movement, the two thread storage sections 17a, 17b can be reliably brought together. Alternatively or additionally it would be Of course, it is also possible that the other thread storage section, in this case the thread storage section 17a, has a corresponding reduction 22 at its end facing the thread storage section 17b (see also Fig. 4 ) having. Of course, the reduction 22 or the extension 19 could also be arranged on the other thread storage section 17a, 17b.

Figur 4 zeigt eine andere Ausführung einer Arbeitsstelle 2 mit einem ersten Arbeitsstellenteil 2a und einem zweiten Arbeitsstellenteil 2b, wobei jedoch der zweite Arbeitsstellenteil 2b linear gegenüber dem ersten Arbeitsstellenteil 2a bewegbar ist, wie durch die Pfeile symbolisiert. Vorliegend weist dabei der zweite Fadenspeicherabschnitt 17b eine Reduzierung 22 auf, welche ein teleskopartiges Ineinandergreifen der beiden Fadenspeicherabschnitte 17a, 17b ermöglicht. Figure 4 shows another embodiment of a job 2 with a first job part 2a and a second job part 2b, but the second job part 2b is linearly movable relative to the first job part 2a, as symbolized by the arrows. In the present case, the second thread storage section 17b has a reduction 22, which enables the two thread storage sections 17a, 17b to interlock telescopically.

Figur 5 zeigt schließlich noch eine andere Ausführung einer Arbeitsstelle 2 mit einem ersten Arbeitsstellenteil 2a und einem zweiten Arbeitsstellenteil 2b, bei welcher jedoch der erste Arbeitsstellenteil 2a kein erstes Trägerelement 27 aufweist, sondern die faserführenden Arbeitsorgane 5, 6, 7, 8, 10, 11, 12, 14, 17, 23, 24 der ersten Gruppe jeweils einzeln oder in kleineren Gruppen zusammengefasst an der Arbeitsstelle 2 angeordnet sind. Vorliegend ist beispielsweise die Spulwalze 14 mittels ihrer Halterung 25 an der Arbeitsstelle 2 befestigt und der zweite Arbeitsstellenteil 2b ist schwenkbar und/oder abnehmbar ebenfalls mittels der Halterung 25 an der Arbeitsstelle 2 befestigt. Der erste Fadenspeicherabschnitt 17a ist hingegen einzeln an der Arbeitsstelle 2 bzw. hier dem Gestellabschnitt 21 befestigt. Die fadenproduzierenden Arbeitsorgane 5, 6, 7, 8 sind zu einer Spinnbox zusammengefasst und damit gemeinsam an dem Gestellabschnitt 21 befestigt. Figure 5 finally shows another embodiment of a work station 2 with a first work part 2a and a second work part 2b, in which, however, the first work part 2a does not have a first carrier element 27, but rather the fiber-carrying work elements 5, 6, 7, 8, 10, 11, 12 , 14, 17, 23, 24 of the first group are arranged individually or combined in smaller groups at work station 2. In the present case, for example, the winding roller 14 is fastened to the work station 2 by means of its holder 25, and the second work part 2 b is pivotably and / or removably likewise fastened to the work station 2 by means of the holder 25. The first thread storage section 17a, however, is individually attached to the work station 2 or here to the frame section 21. The thread-producing working elements 5, 6, 7, 8 are combined to form a spinning box and are thus jointly attached to the frame section 21.

Die Erfindung ist nicht auf die dargestellten Ausführungsbeispiele beschränkt. So ist es beispielsweise nicht unbedingt erforderlich, dass beide Fadenspeicherabschnitte 17a, 17b an der Trennstelle 18 vollständig voneinander lösbar sind. Je nach Ausführung der beiden Arbeitsstellenteile 2a, 2b wäre es ebenfalls denkbar, dass der erste Fadenspeicherabschnitt 17a und der zweite Fadenspeicherabschnitt 17b lediglich relativ zueinander bewegbar sind, jedoch noch zumindest lose oder über ein Drehgelenk miteinander verbunden bleiben. Daneben könnten sowohl die Arbeitsstelle 2 als auch das Fadenspeicherorgan 17 nicht nur einen zweiteiligen, sondern auch einen mehrteiligen Aufbau aufweisen. Ebenso sind bezüglich der gezeigten Ausführungen und Anordnungen der faserführenden und fadenproduzierenden Arbeitsorgane zahlreiche Abwandlungen möglich. Selbiges gilt für die Anordnung der einzelnen Arbeitsorgane 5, 6, 7, 8, 10, 11, 12, 14, 17, 23, 24, die auch auf mehreren ersten Trägerelementen 27 oder mehreren zweiten Trägerelementen 28 befestigt sein können oder auch zumindest teilweise ohne Trägerelemente 27, 28 aneinander befestigt sein können oder, zumindest im Falle des ersten Arbeitsstellenteils 2a, auch einzeln und direkt an dem Gestellabschnitt 21. Weitere Abwandlungen und Kombinationen im Rahmen der Patentansprüche fallen ebenfalls unter die Erfindung.The invention is not restricted to the exemplary embodiments shown. For example, it is not absolutely necessary for the two thread storage sections 17a, 17b to be completely separate from one another at the separation point 18 are solvable. Depending on the design of the two work station parts 2a, 2b, it would also be conceivable that the first thread storage section 17a and the second thread storage section 17b can only be moved relative to one another, but remain at least loosely or connected to one another via a swivel joint. In addition, both the work station 2 and the thread storage member 17 could have not only a two-part, but also a multi-part structure. Likewise, numerous modifications are possible with regard to the designs and arrangements of the fiber-guiding and thread-producing working elements shown. The same applies to the arrangement of the individual working elements 5, 6, 7, 8, 10, 11, 12, 14, 17, 23, 24, which can also be fastened to a plurality of first support elements 27 or a plurality of second support elements 28 or at least partially without them Carrier elements 27, 28 can be fastened to one another or, at least in the case of the first work part 2a, also individually and directly to the frame section 21. Further modifications and combinations within the scope of the claims also fall under the invention.
