Description

Die Erfindung betrifft eine Arbeitsstelle einer Offenend-Rotorspinnmaschine gemäß dem Oberbegriff des Anspruches 1.The invention relates to a workstation of an open-end rotor spinning machine according to the preamble of claim 1.

Offenend-Rotorspinnmaschinen sind in verschiedenen Ausführungsformen bekannt und in zahlreichen Patentanmeldungen ausführlich beschrieben.
Offenend-Rotorspinnmaschinen verfügen in der Regel über eine Vielzahl gleichartiger, in Reihe nebeneinander angeordneter Arbeitsstellen, auf denen jeweils ein zum Beispiel in einer Spinnkanne vorgelegtes Faserband zu einem Faden versponnen wird, der anschließend zu einer Kreuzspule aufgewickelt wird.
Die Arbeitsstellen derartiger Offenend-Rotorspinnmaschinen verfügen zu diesem Zweck jeweils unter anderem über eine Offenend-Spinnvorrichtung zur Fertigung des Fadens sowie über eine Spulvorrichtung zur Herstellung der Kreuzspule.Open-end rotor spinning machines are known in various embodiments and described in detail in numerous patent applications.
Open-end rotor spinning machines generally have a plurality of similar, in series juxtaposed jobs, on each of which, for example, presented in a sliver can sliver is spun into a thread, which is then wound into a cross-wound bobbin.
The workstations of such open-end rotor spinning machines have for this purpose in each case, inter alia, an open-end spinning device for producing the thread and a winding device for producing the cross-wound bobbin.

Bezüglich ihrer weiteren Ausgestaltung sowie der damit verbundenen Arbeitsweise, insbesondere beim Auftreten von Fadenbrüchen, können sich die Arbeitsstellen solcher Offenend-Rotorspinnmaschinen allerdings erheblich unterscheiden.With regard to their further embodiment and the associated operation, in particular when thread breaks occur, however, the jobs of such open-end rotor spinning machines can differ considerably.

Durch die DE 199 52 438 A1 sind beispielsweise Offenend-Rotorspinnmaschinen bekannt, bei denen die verschiedenen Arbeitsorgane der zahlreichen Arbeitsstellen über maschinenendseitig angeordnete Zentralantriebe gemeinsam beaufschlagt werden.By the DE 199 52 438 A1 For example, open-end rotor spinning machines are known in which the various work organs of the numerous workstations are acted upon jointly on the machine end side arranged central drives.

Die Arbeitsstellen dieser Offenend-Rotorspinnmaschinen werden im Falle eines Fadenbruches durch ein spezielles Serviceaggregat, einen so genannten Anspinnwagen, versorgt. Das heißt, bei diesen Offenend-Rotorspinnmaschinen patrouilliert während des Spinnbetriebes ein Anspinnwagen entlang der Arbeitsstellen und greift bei einem Fadenbruch an einer der Arbeitsstellen helfend ein.The jobs of these open-end rotor spinning machines are supplied in the event of a yarn breakage by a special service unit, a so-called piecing. That is, these open-end rotor spinning machines patrolled during the spinning operation a piecing along the jobs and engages in a thread break at one of the jobs helping.

In der DE 10 2007 056 561 A und der DE 10 2009 030 802 A1 sind Offenend-Rotorspinnmaschinen beschrieben, die über so genannte autarke Arbeitsstellen verfügen, das heißt, diese Offenend-Rotorspinnmaschinen weisen Arbeitsstellen auf, die einen Fadenbruch selbsttätig beheben können.
Die Arbeitsstellen sind zu diesem Zweck jeweils unter anderem mit einer schwenkbar gelagerten Saugdüse ausgestattet, die nach einem Fadenbruch mit ihrer unterdruckbeaufschlagbaren Mündung in den Bereich der Oberfläche der zu diesem Zeitpunkt in Abwickelrichtung drehenden Kreuzspule geschwenkt wird und das nach dem Fadenbruch auf die Kreuzspule aufgelaufene Fadenende pneumatisch aufnimmt.
Die Saugdüse überführt das aufgenommene Fadenende anschließend an eine Anspinnvorrichtung im Bereich der Offenend-Spinnvorrichtung, die dafür sorgt, dass die betroffene Arbeitsstelle wieder neu angesponnen wird.In the DE 10 2007 056 561 A and the DE 10 2009 030 802 A1 Open-end rotor spinning machines are described which have so-called autarkic jobs, that is, these open-end rotor spinning machines have jobs that can fix a thread break automatically.
The jobs are each equipped for this purpose, inter alia, with a pivotally mounted suction nozzle, which is pivoted after a yarn breakage with their unterdruckbeaufschlagbaren mouth in the area of the surface of the currently rotating in the unwinding cheese and the accumulated after the yarn breakage on the cheese spool end pneumatic receives.
The suction nozzle then transfers the recorded thread end to a piecing device in the region of the open-end spinning device, which ensures that the affected workstation is re-spun again.

Bei den durch die DE 10 2007 056 561 A und/oder die DE 10 2009 030 802 A1 bekannten, autarken Arbeitsstellen sind sowohl die Arbeitsorgane der Offenend-Spinnvorrichtungen, als auch die Arbeitsorgane der Spulvorrichtungen jeweils einzelmotorisch angetrieben. Auch die Saugdüsen dieser Arbeitsstellen sind jeweils mit einem eigenen Antrieb ausgestattet, so dass die Saugdüsen bei Bedarf stets definiert ansteuerbar sind.At the by the DE 10 2007 056 561 A and / or the DE 10 2009 030 802 A1 Known, self-sufficient workstations are both the working organs of the open-end spinning devices, as well as the working organs of the winding devices each driven by a single motor. The suction nozzles of these jobs are each equipped with its own drive, so that the suction nozzles are always controlled defined if necessary.

Wenngleich die Arbeitsstellen solcher Offenend-Rotorspinnmaschinen, wie vorstehend erläutert, weitestgehend autark arbeiten, sind auch solche Offenend-Rotorspinnmaschinen in der Regel mit einem entlang der Arbeitsstellen verfahrbaren Serviceaggregat, einem so genannten Kreuzspulenwechsler, ausgestattet. Der Kreuzspulenwechsler sorgt bei derartigen Offenend-Rotorspinnmaschinen einerseits dafür, dass im Bedarfsfall eine fertige Kreuzspule aus der Spulvorrichtung einer Arbeitsstelle auf die maschinenlange Kreuzspulen-Transporteinrichtung der Offenend-Rotorspinnmaschine überführt und eine neue Kreuzspulenhülse in die Spulvorrichtung der betreffenden Arbeitsstelle eingewechselt wird, und hat anderseits die Aufgabe, die Bereiche der Arbeitsstellen, die während des Spinnbetriebes unter besonders starker Verschmutzung leiden, zu reinigen.
Der Kreuzspulenwechsler ist zu diesem Zweck mit einer Reinigungseinrichtung ausgestattet, die von Zeit zu Zeit mittels Blasdüsen die zu reinigenden Bereiche der Arbeitsstellen mit einem Blasluftstrom beaufschlagt.Although the jobs of such open-end rotor spinning machines, as explained above, work largely independently, such open-end rotor spinning machines are usually equipped with a movable along the workstations service unit, a so-called cheese changer. The cheese changer ensures in such open-end rotor spinning on the one hand that, if necessary, a finished cheese from the winding device of a job transferred to the machine-length cheese winding device of the open-end rotor spinning machine and a new cheese package is inserted into the winding device of the relevant job, and on the other hand Task to clean the areas of the workplaces, which suffer from particularly heavy soiling during the spinning operation.
The cheese changer is equipped for this purpose with a cleaning device which acts from time to time by means of blowing nozzles to be cleaned areas of the jobs with a blast of air.

Bei solchen autarken Arbeitsstellen besteht allerdings das Problem, dass die Saugdüsen beim Abschalten ihres Antriebes schwerkraftbedingt in eine untere Stellung absinken, in der sie eine ordnungsgemäße Reinigung der kritischen Bereiche der Arbeitsstellen durch den Kreuzspulenwechsler behindern.
Um dies zu vermeiden, werden die Saugdüsen deshalb bislang durch ihren Antrieb ständig in einer vorgegebenen, so genannten Ruhestellung gehalten, in der sie außerhalb der Wirkungsbereiche der vom Kreuzspulenwechsler initiierbaren Blasluftströme stehen.In such self-sufficient jobs, however, there is the problem that the suction nozzles fall when switching off their drive due to gravity in a lower position in which they hinder a proper cleaning of the critical areas of the jobs by the cheese changer.
In order to avoid this, the suction nozzles are therefore so far held by their drive constantly in a predetermined, so-called rest position in which they are outside the range of action of initiatable by the cheese changer Blasluftströme.

Wenngleich der bei der elektrischen Positionierung einer Saugdüse auftretende Stromverbrauch relativ gering ist, wirkt sich dieser Stromverbrauch angesichts der Vielzahl der Saugdüsen sowie der relativ langen Zeitdauer der Positionierung insgesamt doch recht nachteilig aus. Das heißt, die elektrische Positionierung der Saugdüsen während des Spinnbetriebes macht sich bezüglich der Betriebskosten einer solchen Offenend-Rotorspinnmaschine negativ bemerkbar.Although the current consumption occurring in the electrical positioning of a suction nozzle is relatively low, this power consumption has a rather disadvantageous effect in view of the large number of suction nozzles and the relatively long duration of the positioning. That is, the electrical positioning of the suction nozzles during the spinning operation makes a negative impact on the operating costs of such an open-end rotor spinning machine.

Ausgehend vom vorgenannten Stand der Technik liegt der Erfindung die Aufgabe zugrunde, die autarken Arbeitstellen derartiger Offenend-Rotorspinnmaschinen dahingehend zu modifizieren, dass die Saugdüsen solcher Arbeitsstellen möglichst kostengünstig in Ruhestellungen positionierbar sind, in denen sie den pneumatischen Reinigungsprozess des Kreuzspulenwechslers nicht behindern.Based on the aforementioned prior art, the present invention seeks to modify the autarkic workstations such open-end rotor spinning machines to the effect that the suction nozzles such jobs are positioned as cost as possible in rest positions in which they do not hinder the pneumatic cleaning process of the cheese change.

Diese Aufgabe wird erfindungsgemäß durch eine Arbeitsstelle gelöst, die die im Anspruch 1 beschriebenen Merkmale aufweist.This object is achieved by a job, which has 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 im Anspruch 1 beschriebene Ausbildung einer Arbeitsstelle einer Offenend-Rotorspinnmaschine mit einer Arretiereinrichtung, die ein Arretieren der Saugdüse in einer vorgegeben Ruhestellung ermöglicht, hat insbesondere den Vorteil, dass die Saugdüse durch eine solche Arretiereinrichtung auf einfache, sichere und kostengünstige Weise in einer vorgegebenen Ruhestellung fixiert werden kann. Das heißt, die erfindungsgemäße Arretiereinrichtung sorgt zuverlässig dafür, dass eine durch ihren Antrieb in die Ruhestellung geschwenkte Saugdüse auch nach dem Abschalten ihres Antriebes zuverlässig in der vorgegebenen Ruhestellung gehalten bleibt.The described in claim 1 training a job of an open-end rotor spinning machine with a locking device that allows locking the suction nozzle in a predetermined rest position, in particular has the advantage that the suction nozzle by such a locking device in a simple, safe and cost-effective manner in a predetermined rest position can be fixed. That is, the locking device according to the invention reliably ensures that a swung by its drive in the rest position suction nozzle reliably remains in the predetermined rest position even after switching off its drive.

Wie im Anspruch 2 beschrieben, ist in vorteilhafter Ausführungsform vorgesehen, dass die Arretiereinrichtung im Bereich der Schwenkachse der Saugdüse angeordnet ist.
Durch eine solche Anordnung der Arretiereinrichtung kann der konstruktive Aufwand, der für die Entwicklung einer Arretiereinrichtung notwendig ist, minimiert, und auf relativ einfache Weise sichergestellt werden, dass die Saugdüse einerseits gut fixierbar und anderseits schwenkbeweglich verstellbar ist.As described in claim 2, it is provided in an advantageous embodiment that the locking device is arranged in the region of the pivot axis of the suction nozzle.
Such an arrangement of the locking device, the design effort that is necessary for the development of a locking device minimized, and be ensured in a relatively simple manner that the suction nozzle on the one hand well fixable and on the other hand is pivotally adjustable.

Wie in den Ansprüchen 3 - 5 dargelegt, ist die erfindungsgemäße Arretiereinrichtung vorzugsweise als mechanisch arbeitende Vorrichtung ausgebildet, die die Saugdüse bei abgeschaltetem Antrieb kraftschlüssig fixiert.
Die Arretiereinrichtung verfügt zu diesem Zweck über ein erstes, stationär angeordnetes Positioniermittel, das, durch ein Federelement beaufschlagt, mit einem zweiten Positioniermittel korrespondiert, das seinerseits drehfest mit der Saugdüse verbunden und damit mit der Saugdüse schwenkbar gelagert ist. Das erste Positioniermittel, das vorzugsweise eine gerundete Form aufweist, wird durch das Federelement kraftschlüssig vor einem durch das zweite Positioniermittel gebildeten Anschlag positioniert und verhindert dadurch, dass die Saugdüse beim Ausschalten ihres Antriebes schwerkraftbedingt nach unten wegschwenken und in eine den Reinigungsprozess störende Stellung gelangen kann.As set out in claims 3 to 5, the locking device according to the invention is preferably designed as a mechanically operating device which fixes the suction nozzle in a force-locking manner when the drive is switched off.
For this purpose, the locking device has a first, stationary positioning means, which, acted upon by a spring element, corresponds to a second positioning means, which in turn is non-rotatably connected to the suction nozzle and thus pivotally mounted with the suction nozzle. The first positioning means, which preferably has a rounded shape, is frictionally positioned by the spring element in front of a stop formed by the second positioning means and thereby prevents the suction nozzle pivoting downwards when its drive is switched off and can reach a position disturbing the cleaning process.

Gemäß Anspruch 6 ist der Antrieb der Saugdüse als Schrittmotor ausgebildet, der über eine Steuerleitung so mit einem Arbeitsstellenrechner verbunden ist, dass die Saugdüse mittels des Schrittmotors jederzeit exakt definiert geschwenkt werden kann. Das heißt, die durch den Schrittmotor beaufschlagte Saugdüse kann zwischen einer Fadenaufnahmestellung, in der die Mündungsöffnung der Saugdüse in unmittelbarer Nähe der Mantelfläche einer im Spulenrahmen einer Spulvorrichtung gehaltenen und in Abwickelrichtung rotierten Kreuzspule positioniert ist, einer Fadenübergabestellung, in der der aufgenommene Faden einem Anspinnorgan im Bereich der Spinnvorrichtung vorgelegt wird, oder einer Ruhestellung, in der die Saugdüse die Reinigung der Arbeitsstelle durch den Kreuzspulenwechsler nicht behindert, verschwenkt werden.
Die Verwendung eines Schrittmotors als Saugdüsenantrieb hat dabei außerdem den Vorteil, dass der zum exakten Positionieren erforderliche Steuerungsaufwand relativ gering ist. Schrittmotoren stellen zudem in der Praxis bewährte, im Handel kostengünstig erhältliche Serienbauteile dar.According to claim 6, the drive of the suction nozzle is designed as a stepper motor, which is connected via a control line to a workstation computer, that the suction nozzle by means of the stepping motor can be swiveled exactly defined at any time. That is, the acted upon by the stepping motor suction nozzle can between a thread receiving position in which the mouth opening of the suction nozzle is positioned in the immediate vicinity of the lateral surface of a reel held in the bobbin of a winding device and in the unwinding cheese, a yarn transfer position in which the recorded thread a Anspinnorgan in Spinning device is presented, or a rest position in which the suction nozzle does not interfere with the cleaning of the job by the cheese change, are pivoted.
The use of a stepping motor as Saugdüsenantrieb also has the advantage that the exact positioning required control effort is relatively low. Stepper motors are also proven in practice, commercially available at low cost serial components.

Im Anspruch 7 ist des Weiteren dargelegt, dass der Schrittmotor und die Arretiereinrichtung vorzugsweise so dimensioniert sind, dass der Schrittmotor bei Bedarf die Arretiereinrichtung jederzeit überdrücken und die Saugdüse dann problemlos aus der Ruhestellung herausschwenken kann.
Das bedeutet, die Arretiereinrichtung fixiert zwar bei abgeschaltetem Antrieb die Saugdüse sicher in ihrer Ruhestellung, behindert aber bei einem Fadenbruch das ordnungsgemäße Schwenken der Saugdüse in keiner Weise.In claim 7 is further set forth that the stepper motor and the locking device are preferably dimensioned so that the stepper motor, if necessary, overpress the locking device and then easily swivel the suction nozzle out of the rest position.
This means that the locking device, while the drive is switched off, securely secures the suction nozzle in its rest position, but in no way hampers the proper pivoting of the suction nozzle during a yarn breakage.

Die Figur 1 zeigt schematisch in Vorderansicht eine Offenend-Rotorspinnmaschine 40 mit Endgestellen 41, 42 und einer Vielzahl zwischen den Endgestellen 41, 42 angeordneten gleichartigen, autarken Arbeitsstellen 1.The FIG. 1 schematically shows a front view of an open-end rotor spinning machine 40 with end frames 41, 42 and a plurality between the end frames 41, 42 arranged similar, self-sufficient work places. 1

In den Endgestellen 41 bzw. 42 sind dabei, wie üblich, beispielsweise eine textilmaschineneigene Unterdruckquelle 45, eine elektrische Energieversorgung sowie eine Zentralsteuereinheit 46 der Offenend-Rotorspinnmaschine 40 angeordnet.
Die Zentralsteuereinheit 46 ist ihrerseits mit den Arbeitsstellenrechnern 47 der einzelnen Arbeitsstellen 1, vorzugsweise über ein Bussystem 43, verbunden.In the end frames 41 and 42 are, as usual, for example, a textile machine's own vacuum source 45, an electrical power supply and a central control unit 46 of the open-end rotor spinning machine 40 are arranged.
The central control unit 46 is in turn connected to the workstation computers 47 of the individual workstations 1, preferably via a bus system 43.

Die zahlreichen Arbeitsstellen 1 weisen jeweils ein Arbeitsstellengehäuse 11 mit einer Offenend-Spinnvorrichtung 2, einer Spulvorrichtung 44, einer Saugdüse 4 sowie weiteren bekannten Fadenbehandlungseinrichtungen, wie beispielsweise einer Paraffiniereinrichtung 5, auf.
Auf den Arbeitsstellen 1 wird jeweils mittels der Offenend-Spinnvorrichtung 2 ein Vorlagefaserband 48, das in Spinnkannen 49 bevorratet ist, die in Reihe nebeneinander unterhalb der Arbeitsstellen 1 positioniert sind, zu einem Faden 3 gesponnen, der anschließend auf der Spulvorrichtung 44 zu einer Kreuzspule 8 aufgewickelt wird.The numerous work stations 1 each have a workstation housing 11 with an open-end spinning device 2, a winding device 44, a suction nozzle 4 and other known yarn treatment devices, such as a waxing device 5, on.
On the workstations 1 is in each case by means of the open-end spinning device 2, a master fiber belt 48, which is stored in spinning cans 49, which are positioned in series next to each other below the jobs 1, spun into a yarn 3, which then on the winding device 44 to a cheese 8 is wound up.

Die Offenend-Rotorspinnmaschine 40 ist außerdem mit einem entlang der Arbeitsstellen 1 verfahrbaren Kreuzspulenwechsler 6 ausgestattet, der nicht nur im Bedarfsfall fertige Kreuzspulen 8 gegen frische Kreuzspulenhülsen 10 wechselt, sondern der auch eine pneumatische Reinigungseinrichtung 7, vorzugsweise in Form einer Blasvorrichtung, aufweist.The open-end rotor spinning machine 40 is also equipped with a movable along the workstations 1 cheese changer 6, which not only in case of need finished cross-wound bobbin 8 to fresh cheese packages 10, but also a pneumatic cleaning device 7, preferably in the form of a blowing device having.

In Fig. 2 ist in Seitenansicht eine der zahlreichen, autarken Arbeitsstellen 1 einer Offenend-Rotorspinnmaschine 40 dargestellt.
Wie ersichtlich und vorstehend bereits angedeutet, sind derartige Arbeitsstellen 1 jeweils unter anderem mit einer Offenend-Spinnvorrichtung 2, einer Spulvorrichtung 44 sowie einer definiert schwenkbaren Saugdüse 4 ausgestattet.
In der Spinnvorrichtung 2 wird das in der Spinnkanne 49 vorgelegte Faserband 48 zu einem Faden 3 gesponnen, der später auf der Spulvorrichtung 44 zu einer Kreuzspule 8 aufgewickelt wird.In Fig. 2 is one of the numerous, self-sufficient jobs 1 an open-end rotor spinning machine 40 shown in side view.
As can be seen and already indicated above, such jobs 1 are each equipped inter alia with an open-end spinning device 2, a winding device 44 and a defined pivotable suction nozzle 4.
In the spinning device 2, the sliver 48 presented in the spinning can 49 is spun to a yarn 3, which is later wound up on the winding device 44 to form a cross-wound bobbin 8.

Die Offenend-Spinnvorrichtung 2 weist, wie üblich, einen von einem Antrieb 27 angetriebenen rotierenden Spinnrotor 26 auf, dem das Faserband 48 mittels einer Faserbandeinzugswalze 25 zugeführt wird.
Der fertige Faden 3 wird mittels einer Fadenabzugseinrichtung 35 aus der Offenend-Spinnvorrichtung 2 gezogen und läuft zur Spulvorrichtung 44, wo er zu einer Kreuzspule 8 aufgewickelt wird. Die Kreuzspule 8 ist dabei in einem Spulenrahmen 9 frei drehbar gehaltert und wird durch eine einzelmotorisch angetriebene Spultrommel 12 rotatorisch beaufschlagt.The open-end spinning device 2 has, as usual, a driven by a drive 27 rotating spinning rotor 26 to which the sliver 48 is fed by means of a sliver feed roller 25.
The finished thread 3 is pulled out of the open-end spinning device 2 by means of a thread withdrawal device 35 and runs to the winding device 44, where it is wound up into a cross-wound bobbin 8. The cross-wound bobbin 8 is held freely rotatably in a creel 9 and is acted upon rotationally by a single-motor driven winding drum 12.

Die Arbeitsstelle 1 verfügt des Weiteren über eine ebenfalls einzelmotorisch antreibbare Fadenchangiereinrichtung 18 sowie über ein Anspinnorgan 20. Das heißt, jede der Arbeitsstellen 1 ist so ausgerüstet, dass sie bei Bedarf Fadenbrüche selbsttätig beheben können.The workstation 1 further has a threading device 18, which can likewise be driven by a single motor, and by means of a piecing element 20. That is, each of the workstations 1 is equipped so that you can automatically correct thread breaks if necessary.

Die Saugdüse 4 der Arbeitsstelle 1 ist mittels ihres Schrittmotors 28 definiert zwischen einer Fadenaufnahmestellung, in der die Mündung der Saugdüse 4 im Bereich der im Spulenrahmen 9 gehalterten Kreuzspule 8 positioniert ist, einer Fadenübergabestellung im Bereich der Spinnvorrichtung 2 sowie einer Ruhestellung 29 verschwenkbar.
In der Ruhestellung 29 ist die Saugdüse 4 außerdem durch eine erfindungsgemäße, vorzugsweise mechanisch arbeitende Arretiereinrichtung 30 fixiert, die nachfolgend anhand der Figuren 3 und 4 näher erläutert werden wird.The suction nozzle 4 of the workstation 1 is defined by means of its stepping motor 28 between a thread receiving position in which the mouth of the suction nozzle 4 is positioned in the region of the cross-wound bobbin 8 held in the creel 9, a yarn transfer position in the spinning device 2 and a rest position 29.
In the rest position 29, the suction nozzle 4 is also fixed by an inventive, preferably mechanically operating locking device 30, which is described below with reference to Figures 3 and 4 will be explained in more detail.

Wie aus Fig.2 weiter ersichtlich, ist an beziehungsweise auf der Offenend-Rotorspinnmaschine 40, beispielsweise an einer Führungsschiene 13 sowie einer Stützschiene 15 verfahrbar, ein Kreuzspulenwechsler 6 angeordnet.
Das Laufwerk dieses Kreuzspulenwechslers 6 besteht aus Laufrollen 17 beziehungsweise Stützrädern 19.
Derartige Kreuzspulenwechsler 6 patrouillieren entlang der Arbeitsstellen 1 der Offenend-Rotorspinnmaschine 40 und greifen selbsttätig ein, wenn an einer der Arbeitsstellen 1 ein Handlungsbedarf entsteht.
Ein solcher Handlungsbedarf liegt beispielsweise vor, wenn an einer der Arbeitsstellen 1 eine volle Kreuzspule 8 gegen eine neue Kreuzspulenhülse 10 ausgetauscht werden muss, das heißt, wenn eine fertige Kreuzspule 8 an die maschinenlange Kreuzspulen-Transporteinrichtung 14 übergeben und eine neue Kreuzspulenhülse 10 in den Spulenrahmen 9 eingelegt werden muss.
Der Kreuzspulenwechsler 6 verfügt zu diesem Zweck, wie bekannt, über zahlreiche Handhabungseinrichtungen, die einen ordnungsgemäßen Kreuzspulen-/Leerhülsenwechsel ermöglichen.How out Fig.2 can also be seen, is on or on the open-end rotor spinning machine 40, for example, on a guide rail 13 and a support rail 15 movable, a cheese changer 6 is arranged.
The drive of this cheese changer 6 consists of rollers 17 and support wheels 19th
Such cheeses 6 patrol along the work stations 1 of the open-end rotor spinning machine 40 and automatically engage when at one of the jobs 1 a need for action arises.
Such a need for action exists, for example, when at one of the jobs 1 a full cross-wound bobbin 8 must be replaced by a new cheese package 10, that is, when a finished cross-wound bobbin 8 handed over to the machine-length cross-bobbin transport device 14 and a new cheese package 10 in the creel 9 must be inserted.
The cheese changer 6 has for this purpose, as is known, numerous handling devices that allow a proper cheese / empty tube change.

Da der Kreuzspulen-/Leerhülsenwechselvorgang nicht Gegenstand der vorliegenden Erfindung ist, wurde auf eine Darstellung und weitere Erläuterung der zahlreichen, an sich bekannten Handhabungseinrichtungen des Kreuzspulenwechslers verzichtet.Since the cheese / Leerhülsenwechselvorgang is not the subject of the present invention, has been dispensed with a representation and further explanation of the numerous, known handling means of the cheese change.

Der Kreuzspulenwechsler 6 gemäß vorliegendem Ausführungsbeispiel verfügt zusätzlich über eine vorzugsweise pneumatisch arbeitende Reinigungseinrichtung 7.
Das heißt, der Kreuzspulenwechsler 6 weist eine Reinigungseinrichtung 7 auf, deren Blasluftdüsen 22 an eine Überdruckquelle 23 angeschlossen sind.
Über diese Blasluftdüsen 22 können im Bedarfsfall gerichtete Druckluftströme 24 auf verschmutzungsgefährdete Bereiche der Arbeitsstellen 1 geschickt und diese dadurch gereinigt werden.The cheese changer 6 according to the present embodiment additionally has a preferably pneumatically operating cleaning device 7.
That is, the cheese changer 6 has a cleaning device 7, the Blasluftdüsen 22 are connected to a pressure source 23.
If necessary, directed compressed air streams 24 can be sent to polluted areas of the workstations 1 via these blown air nozzles 22, thereby cleaning them.

Die Fig.3 zeigt in Vorderansicht und in einem größeren Maßstab eine der Arbeitsstellen 1 der Offenend-Rotorspinnmaschine 40 während des Spinnprozesses.
Das heißt, in der Offenend-Spinnvorrichtung 2 wird ein über die Faserbandeinzugswalze 25 eingespeistes Faserband 48 zu einem fertigen Faden 3 gesponnen, der durch die Fadenabzugseinrichtung 35 abgezogen wird.
Der fertige Faden 3 tangiert auf seinem Weg zur Kreuzspule 8 das Anspinnorgan 20, den Fadenreiniger 21, den Fadenspanner 16 sowie die Paraffiniereinrichtung 5, bevor er, durch die Fadenchangiereinrichtung 18 traversiert, auf die rotatorisch angetriebene Kreuzspule 8 aufläuft.
Wie in Fig.3 dargestellt, ist die Saugdüse 4 während dieses Spinnprozesses in der Ruhestellung 29 positioniert und wird dabei durch die Arretiereinrichtung 30 zuverlässig fixiert.The Figure 3 shows in front view and on a larger scale one of the jobs 1 of the open-end rotor spinning machine 40 during the spinning process.
That is, in the open-end spinning device 2, a sliver 48 fed via the sliver feed roller 25 is spun into a finished yarn 3 which is drawn off by the yarn take-off device 35.
The finished thread 3 is tangent on its way to the cheese 8 the Anspinnorgan 20, the thread cleaner 21, the thread tensioner 16 and the waxing device 5 before he traversed by the Fadenchangiereinrichtung 18, runs on the rotationally driven cheese 8.
As in Figure 3 shown, the suction nozzle 4 is positioned during this spinning process in the rest position 29 and is thereby reliably fixed by the locking device 30.

Die vorzugsweise mechanisch arbeitende Arretiereinrichtung 30 verfügt beispielsweise, wie insbesondere aus Fig.4 ersichtlich, über ein erstes, vorzugsweise gerundetes Positionierelement 32, das endseitig eines zum Beispiel als Blattfeder ausgebildeten Federelementes 31 angeordnet ist.The preferably mechanically operating locking device 30 has, for example, as in particular Figure 4 visible, via a first, preferably rounded positioning element 32, the end of a spring element 31, designed for example as a leaf spring, is arranged.

Das Federelement 31 ist dabei über ein Widerlager 36 stationär so am Arbeitsstellengehäuse 11 festgelegt, dass das Positionierelement 32 in Richtung eines drehfest an der Saugdüse 4 angeordneten zweiten Positionierelements 33 beaufschlagt wird. Dieses zweite Positionierelement 33 weist an seiner Vorderseite eine auf das gerundete Positionierelement 32 abgestimmte Anschlagkante auf.
Das bedeutet, beim Einschwenken der Saugdüse 4 in die Ruhestellung 29 gleitet das erste Positionierelement 32 automatisch so hinter die Anschlagkante des zweiten Positionierelements 33, dass die Saugdüse 4 kraftschlüssig fixiert wird.The spring element 31 is fixed via an abutment 36 stationarily on the workstation housing 11 in such a way that the positioning element 32 is acted upon in the direction of a second positioning element 33 arranged non-rotatably on the suction nozzle 4. This second positioning element 33 has on its front side a stop edge matched to the rounded positioning element 32.
This means that when pivoting the suction nozzle 4 in the rest position 29, the first positioning member 32 automatically slides behind the stop edge of the second positioning member 33 so that the suction nozzle 4 is fixed non-positively.

Durch entsprechende Dimensionierung von Arretiereinrichtung 30 und Schrittmotor 28 wird dabei gewährleistet, dass einerseits, wenn der Antrieb der Saugdüse 4 abgeschaltet wird, eine sichere Fixierung der Saugdüse 4 in der Ruhestellung 29 gegeben ist, aber anderseits auch sichergestellt, dass der Schrittmotor 28, wenn Bedarf besteht, die Saugdüse 4 stets problemlos aus der Ruhestellung 26 herausschwenken kann.
Das heißt, die Saugdüse 4 kann, wenn zum Beispiel an der Arbeitsstelle ein Fadenbruch aufgetreten ist, problemlos sowohl in die Fadenendaufnahmestellung im Bereich der Kreuzspule 8, als auch anschließend in die Fadenübergabestellung im Bereich der Offenend-Rotorspinnvorrichtung 2 geschwenkt werden.By appropriate dimensioning of locking device 30 and stepper motor 28 is thereby ensured that on the one hand, when the drive of the suction nozzle 4 is turned off, a secure fixation of the suction nozzle 4 is given in the rest position 29, but on the other hand also ensures that the stepper motor 28, if needed exists, the suction nozzle 4 can always easily swing out of the rest position 26.
That is, the suction nozzle 4, if, for example, a thread breakage has occurred at the workplace, easily be pivoted both in the yarn end receiving position in the cross-wound bobbin 8, and then in the yarn transfer position in the field of open-end rotor spinning device 2.
