Description
Die Erfindung betrifft ein Verfahren zum Betreiben einer Arbeitsstelle gemäß dem Oberbegriff des Anspruches 1.The invention relates to a method for operating a workstation according to the preamble of claim 1.
Im Zusammenhang mit dem Betrieb von Arbeitsstellen von Kreuzspulautomaten ist der Einsatz von Fadenspleißvorrichtungen zum pneumatischen Verbinden von Garnen seit langem bekannt und in verschiedenen Patentschriften ausführlich beschrieben.In connection with the operation of work stations of automatic packages, the use of yarn splicing devices for the pneumatic joining of yarns has long been known and described in detail in various patents.
Mit solchen Fadenspleißvorrichtungen können zwei nach einer Spulunterbrechung, zum Beispiel nach einem Fadenbruch oder einem kontrollierten Reinigerschnitt, entstandene Fadenenden pneumatisch wieder so verbunden werden, dass eine nahezu garngleiche Verbindungsstelle entsteht.With such yarn splicing devices, two yarn ends produced after a winding interruption, for example after a yarn breakage or a controlled cleansing cut, can again be pneumatically reconnected so that an almost yarn-like joint results.
Zu diesem Zweck wird der so genannte Oberfaden, der nach einer Spulunterbrechung auf die Oberfläche einer im Spulenrahmen einer Arbeitsstelle gehalterten Kreuzspule aufgelaufen ist, mittels einer arbeitsstelleneigenen Saugdüse aufgenommen und in den Spleißkanal des Spleißprismas der Fadenspleißvorrichtung eingelegt.For this purpose, the so-called upper thread that has accumulated after a Spulunterbrechung on the surface of a held in the creel of a job cross-cheese, picked up by means of a workstation's own suction nozzle and inserted into the splice channel of the splicing prism of Fadensleißvorrichtung.
Nahezu gleichzeitig wird außerdem durch ein Greiferrohr auch der so genannte Unterfaden von einer in einer Abspulstellung positionierten Ablaufspule abgeholt und ebenfalls in den Spleißkanal des Spleißprismas eingelegt, wo Ober- und Unterfaden letztendlich pneumatisch verbunden werden.Almost at the same time, the so-called bobbin thread is also picked up by a discharge bobbin positioned in an unwinding position and also inserted into the splicing channel of the splicing prism, where upper and bobbin threads are finally connected pneumatically by a gripper tube.
Damit die dabei entstehende Garnverbindung ein nahezu garngleiches Aussehen und auch annähernd gleiche Garnfestigkeit aufweist, müssen die beiden Fadenenden exakt abgelängt, ordnungsgemäß vorbereitet und sauber pneumatisch verspleißt werden. Das bedeutet, derartige Fadenspleißvorrichtungen müssen nicht nur mit Fadenklemm- und -schneideinrichtungen ausgestattet sein, sondern auch über einen Spleißkopf verfügen, der mit pneumatisch beaufschlagbaren Halte- und Auflöseröhrchen sowie einem pneumatisch beaufschlagbaren Spleißprisma ausgestattet ist.In order for the resulting yarn compound has a nearly yarn-like appearance and also approximately the same yarn strength, the two thread ends must be exactly cut to length, properly prepared and neatly spliced pneumatically. That is, such Fadensleiißvorrichtungen not only need to be equipped with thread clamping and cutting devices, but also have a splicing head, which is equipped with pneumatically actuated holding and Auflöseröhrchen and a pneumatically acted splicing prism.
Da auf den Arbeitsstellen derartiger Kreuzspulautomaten verschiedene Garnmaterialen verarbeitet werden können, die sowohl hinsichtlich ihrer Vorbereitung als auch bezüglich des Spleißprozesses oft recht unterschiedliche Anforderungen stellen, sind bei den bekannten Fadenspleißvorrichtungen die Halte- und Auflöseröhrchen sowie das den Spleißkanal enthaltende Spleißprisma auswechselbar im/am Spleißkopf festgelegt.Since different yarn materials can be processed on the workstations of such automatic packages that often make quite different demands both in terms of their preparation and with respect to the splicing process, in the known thread splicing devices, the holding and Auflöseröhrchen and the splice channel containing splice prism are interchangeable set in / on the splicing head ,
Das heißt, die Halte- und Auflöseröhrchen sind, wie beispielsweise in der
Auf dem Deckblech, das seinerseits durch einen, in der
Bei den in der Praxis im Einsatz befindlichen Fadenspleißvorrichtungen ist der Verteilerkörper, der von einem Fadenleitbügel umgeben ist, über zwei auf seiner Rückseite einschraubbare Schraubenbolzen an einer Aufnahmeeinrichtung befestigt, die, ebenfalls über Schraubenbolzen, an das Spleißergehäuse der Fadenspleißvorrichtung angeschlossen ist.When in practice in use Fadensleiißvorrichtungen the distributor body, which is surrounded by a Fadenleitbügel, attached via two screwed on its back bolt to a receiving device which is also connected by bolts to the splicer of the Fadensleiißvorrichtung.
Derartig ausgebildete Fadenspleißvorrichtungen haben sich in der Praxis vielfach bewährt, weisen allerdings den Nachteil auf, dass sich der bei einem Partiewechsel notwendige Aufwand, einen ordnungsgemäßen Umbau der Fadenspleißvorrichtungen betreffend, relativ aufwendig und damit zeitintensiv gestaltet.Such trained Fadensleiißvorrichtungen have proven in practice many times, however, have the disadvantage that the costs necessary in a batch change effort, a proper conversion of Fadensleiißvorrichtungen concerning relatively expensive and thus time-consuming designed.
Um auch bei einer neuen Garnpartie stets ordnungsgemäße Fadenverbindungen gewährleisten zu können, ist es oft notwendig, die Fadenspleißvorrichtungen der Arbeitsstellen der Textilmaschine auf das nunmehr vorliegende Garnmaterial abzustimmen.In order to always be able to ensure proper thread connections even with a new yarn section, it is often necessary to tune the Fadenspleißvorrichtungen the workstations of the textile machine to the now present yarn material.
Zu diesem Zweck müssen die Fadenspleißvorrichtungen in der Regel mit neuen Fadenbehandlungselementen (Halte- und Auflöseröhrchen sowie Spleißprisma) ausgestattet werden, die den Anforderungen des neuen Garnmaterials entsprechen.For this purpose, the thread splicing devices usually have to be equipped with new thread treatment elements (holding and dissolving tubes and splicing prism) that meet the requirements of the new yarn material.
Da insbesondere die Halte- und Auflöseröhrchen bei eingebautem Spleißkopf nicht auswechselbar sind und die Befestigungsschrauben, mit denen der Spleißkopf an einer Aufnahmeeinrichtung befestigt ist, nur von der Rückseite zugängig sind, wird bislang zunächst das Spleißergehäuse vom Spulstellengehäuse geschraubt, um dann die den Spleißkopf tragende Aufnahmeeinrichtung samt zugehöriger Druckluftleitungen vom Spleißergehäuse abzunehmen. Nach dem Lösen des Deckbleches konnten dann die alten Halte- und Auflöseröhrchen aus dem Verteilergehäuse herausgeholt und durch Halte- und Auflöseröhrchen ersetzt werden, die besser zum neuen Garnmaterial passen.Since in particular the holding and Auflöseröhrchen are not replaceable with built-in splice head and the mounting screws with which the splice head is attached to a receiving device, accessible only from the back, so far, the splicer housing is first screwed from the winding unit housing, then the splice head supporting receiving device remove associated with compressed air lines from the splicer housing. After loosening the cover plate then the old holding and Auflöseröhrchen could be taken out of the manifold housing and replaced by holding and Auflöseröhrchen that better fit the new yarn material.
In diesem Zusammenhang wurde meistens auch das Spleißprisma gegen ein besser geeignetes Spleißprisma gewechselt und die Druckluftleitungen erneut an die Halte- und Auflöseröhrchen sowie an das Spleißprisma angeschlossen.In this context, the splicing prism was usually replaced by a more suitable splicing prism and the compressed air lines were re-connected to the holding and dissolution tubes and to the splicing prism.
Im Anschluss an diesen Umbau konnte der dann an das neue Garnmaterial angepasste Spleißkopf mittels der Aufnahmeeinrichtung wieder an das Spleißergehäuse angebaut und das Speißergehäuse wieder am Spulstellengehäuse festgelegt werden.Subsequent to this conversion, the splice head, which was then adapted to the new yarn material, could then be re-attached to the splicer housing by means of the receiving device and the spit housing could again be fixed to the winding head housing.
Die vorstehend beschriebenen Arbeiten sind nicht nur relativ umständlich und zeitaufwendig, sondern bergen auch die Gefahr in sich, dass es während des Umbaus zum Einbau falscher Bauteile oder zu einem nicht ordnungsgemäßen Einbau von Bauteilen kommt, was sich in beiden Fällen sehr negativ auf nachfolgende Fadenverbindungen auswirkt.The above-described work is not only relatively cumbersome and time consuming, but also involve the risk that it comes to the installation of incorrect components or improper installation of components during the conversion, which in both cases has a very negative effect on subsequent thread connections ,
Außerdem sind während des Umbaus der Fadenspleißvorrichtungen immer zumindest ein Teil der Arbeitsstellen des Kreuzspulautomaten außer Betrieb, was in der Regel zu nicht unerheblichen Produktionseinbußen führt.In addition, during the reconstruction of the yarn splicing devices always at least a part of the jobs of the cheese winder are out of service, which usually leads to not insignificant production losses.
Des Weiteren ist durch die
An den zentral angeordneten, im Querschnitt runden Fadenspleißkanal, in den eine Einblasdüse mündet, ist beidseitig jeweils eine Halterinne und eine Auflöserinne angeschlossen, wobei die Auflöserinnen ebenfalls Einblasdüsen aufweisen, die abhängig von der Drehrichtung der zu bearbeitenden Fäden positioniert sind. Das bedeutet, die einstückigen blockförmigen Körper sind jeweils entweder für die Bearbeitung von Fäden mit S-Drehung, oder für die Bearbeitung von Fäden mit Z-Drehung konzipiert.At the centrally arranged, in cross-section Fadensleiißkanal in which opens a Einblasdüse, on both sides in each case a holding channel and a Auflöserinne connected, wherein the Aufladerinnen also Einblasdüsen have, which are positioned depending on the direction of rotation of the threads to be processed. That is, the one-piece block-shaped bodies are each designed either for the processing of threads with S-twist, or for the processing of threads with Z-twist.
Nachteilig bei diesen bekannten Fadenspleißvorrichtungen ist, dass bei der Bereitstellung von zwei alternativ einsetzbaren blockförmigen Körpern lediglich die Drehungsrichtung der zu spleißenden Garne berücksichtigt werden kann. Jedoch erfordern Materialwechsel, Garnfeinheitsunterschiede etc. auch den Einsatz insbesondere unterschiedlicher Spleißkanäle und unterschiedliche Auflöseeinrichtungen. Um dies zu berücksichtigen, müssten jeweils unterschiedliche blockförmige Körper, also insgesamt eine Vielzahl solcher in ihrer Herstellung relativ aufwendige und damit kostenintensive blockförmige Körper zur Verfügung gestellt werden.A disadvantage of these known Fadensleiißvorrichtungen is that in the provision of two alternatively usable block-shaped bodies only the direction of rotation of the yarns to be spliced can be considered. However, material changes, Garnfeinheitsunterschiede etc. also require the use in particular of different splice channels and different resolving devices. In order to take this into account, in each case different block-shaped bodies, that is to say a total of a large number of such, would have to be relatively expensive to manufacture and thus costly block-shaped bodies are provided.
Die Fadenspleißvorrichtungen gemäß
Die
Ausgehend von Fadenspleißvorrichtungen der vorstehend beschriebenen Gattung liegt der Erfindung die Aufgabe zugrunde, ein Verfahren zu entwickeln, das es ermöglicht, die im Falle eines Partiewechsels an den Fadenspleißvorrichtungen notwendigen Umbaumaßnahmen deutlich zu vereinfachen.Starting from yarn splicing devices of the type described above, the invention has for its object to develop a method which makes it possible to simplify the necessary in the case of a lot change at the Fadenspleißvorrichtungen conversion measures.
Diese Aufgabe wird erfindungsgemäß durch ein Verfahren gelöst, wie es im Anspruch 1 beschrieben ist.This object is achieved by a method as described in claim 1.
Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous embodiments of the invention are the subject of the dependent claims.
Das erfindungsgemäße Verfahren zum Betreiben einer Arbeitsstelle eines Kreuzspulautomaten hat den Vorteil, dass bei einem Partiewechsel der Spleißkopf, der als vormontierte Baueinheit ausgebildet ist, mittels einer von der Frontseite zugängigen Befestigungseinrichtung als Ganzes schnell und problemlos von einer am Spleißergehäuse angeordneten Aufnahmeeinrichtung sowie den dort installierten Druckluftleitungen abgenommen und durch einen neuen Spleißkopf ersetzt werden kann, dessen vormontierte Fadenbehandlungselemente, wie Spleißprisma und Halte- und Auflöseröhrchen auf die vorliegende Garnpartie abgestimmt sind. Auf diese Weise lassen sich die notwendigen Umbauarbeiten so vereinfachen, dass diese Arbeiten auch von weniger qualifiziertem Bedienpersonal ausgeführt werden können, wobei außerdem der benötigte Zeitaufwand deutlich reduziert und damit die Maschinenausfallzeit des Kreuzspulautomaten minimiert wird.The method according to the invention for operating a working station of a cheese winder has the advantage that, in the case of a batch change, the splicing head, which is designed as a preassembled structural unit, can be quickly and easily removed from a receiving device arranged on the splicer housing and the compressed air lines installed there by means of a fastening device accessible from the front can be removed and replaced by a new splice head, whose pre-mounted thread treatment elements, such as splicing prism and holding and Auflöseröhrchen are tuned to the present Garnpartie. In this way, the necessary conversion work can be simplified so that this work can be performed by less qualified operators, which also significantly reduces the amount of time required and thus the machine downtime of the cheese winder is minimized.
Außerdem kann mit dem erfindungsgemäßen Verfahren auch weitestgehend sichergestellt werden, dass beim Umbauen der Fadenspleißvorrichtung nicht versehentlich falsche Fadenbehandlungselemente kombiniert oder Fadenbehandlungselemente falsch eingebaut werden, was sich später beim Erstellen von Fadenverbindungen sehr negativ auswirken würde.In addition, can be largely ensured with the method according to the invention that when rebuilding the Fadensleißvorrichtung not accidentally combined thread treatment elements or thread processing elements are incorrectly installed, which would later affect the creation of thread connections very negative.
Zur Durchführung des erfindungsgemäßen Verfahrens ist vorteilhafterweise vorgesehen, dass der als vormontierte, garnspezifisch konfigurierte Baueinheit ausgebildete Spleißkopf mit einer Befestigungseinrichtung ausgestattet und so ausgebildet ist, dass der eingebaute Spleißkopf exakt mit fest installierten Druckluftleitungen sowie einer am Spleißergehäuse festgelegtenTo carry out the method according to the invention, it is advantageously provided that the splicing head constructed as a preassembled, yarn-specific configured unit is equipped with a fastening device and designed so that the installed splicing head fits exactly with permanently installed compressed air lines and one at the splicer housing
Aufnahmeeinrichtung korrespondiert, so dass ein schnelles und problemloses Auswechseln des Spleißkopfes möglich ist.Receiving device corresponds, so that a quick and easy replacement of the splice head is possible.
Das bedeutet, es stellt für das Bedienpersonal keinen größeren Aufwand dar, nach einem Partiewechsel Spleißköpfe, die nicht mehr den Anforderungen einer neuen Garnpartie entsprechen, gegen Spleißköpfe auszutauschen, deren Fadenbehandlungselemente, wie Spleißprisma und Halte- und Auflöseröhrchen optimal auf die nunmehr vorliegende Garnpartie abgestimmt sind.This means that it represents for the operator no major effort, after a batch change splicing heads that no longer meet the requirements of a new yarn section to replace splice heads, the thread treatment elements, such as splicing prism and holding and Auflöseröhrchen are optimally matched to the now present Garnpartie ,
Mit der erfindungsgemäßen Fadenspleißvorrichtung können folglich stets auf einfache Weise optimale Arbeitsergebnisse gewährleistet werden, ohne dass bei Partiewechseln, wie bislang üblich, relativ umfangreiche und zeitaufwendige Umbauarbeiten notwendig sind.Consequently, with the yarn splicing device according to the invention, optimum working results can always be ensured in a simple manner, without the need for replacement work, which has been hitherto customary, requiring relatively extensive and time-consuming conversion work.
Die Befestigungseinrichtungen zum Festlegen der Spleißköpfe können dabei verschiedene Ausführungsformen aufweisen.The fastening devices for fixing the splice heads can have different embodiments.
Die Befestigungseinrichtungen können beispielsweise, wie in der Praxis bevorzugt verwendet, durch Schraubenbolzen gebildet werden.For example, the fastening devices may be formed by bolts as is preferred in practice.
Das heißt, der Spleißkopf wird durch Schraubenbolzen fixiert, die jeweils eine im Deckblech und im Verteilerkörper angeordnete Bohrung durchfassen und mit einer Gewindebohrung in der Aufnahmeeinrichtung korrespondieren. Eine solche Schraubverbindung stellt eine im Maschinenbau bewährte Befestigungseinrichtung dar.That is, the splice head is fixed by bolts, each pass through a arranged in the cover plate and the manifold body bore and correspond with a threaded hole in the receiving device. Such a screw connection is a proven in mechanical fastener.
Als weitere, vorteilhafte Ausführungsform kann allerdings auch eine formschlüssige Clipverbindung zum Einsatz kommen.As a further advantageous embodiment, however, a positive clip connection can also be used.
Eine solche Clipverbindung hat den Vorteil, dass sie sehr schnell lösbar bzw. festlegbar ist, was den zum Umbau benötigten Zeitbedarf weiter reduziert. Sehr kurze Umbauzeiten sind auch zu realisieren, wenn eine magnetische Kopplung zum Einsatz kommt. Bei einer solchen magnetischen Kopplung sind beispielsweise in den Verteilerkörper des Spleißkopfes, der aus Kunststoff gefertigt ist, Permanentmagnete eingelassen, die mit der ferromagnetischen Aufnahmeeinrichtung korrespondieren.Such a clip connection has the advantage that it can be released or fixed very quickly, which further reduces the time required for the conversion. Very short conversion times can also be realized if a magnetic coupling is used. In such a magnetic coupling, for example, in the distributor body of the splicing head, which is made of plastic, permanent magnets are embedded, which correspond to the ferromagnetic recording device.
Eine magnetische Kopplung gewährleistet einerseits ein sicheres Festlegen des Spleißkopfes an der Aufnahmeeinrichtung, andererseits ist im Bedarfsfall ein Abnehmen des Spleißkopfes relativ einfach.On the one hand a magnetic coupling ensures a secure fixing of the splicing head to the receiving device, on the other hand, if necessary, a removal of the splicing head is relatively easy.
Die beiden zuletzt beschriebenen Befestigungseinrichtungen weisen außerdem den Vorteil auf, dass sie werkzeuglos handhabbar sind.The two fastening devices last described also have the advantage that they can be handled without tools.

Wie bekannt, weisen derartige Kreuzspulautomaten 1 zwischen ihren (nicht dargestellten) Endgestellen eine Vielzahl gleichartiger Arbeitsstellen 2, im vorliegenden Fall Spulstellen, auf. Auf diesen Arbeitsstellen 2 werden Spinnkopse 9, die beispielsweise auf einer (nicht dargestellten) Ringspinnmaschine produziert wurden, zu großvolumigen Kreuzspulen 15 umgespult, die nach ihrer Fertigstellung mittels eines selbsttätig arbeitenden (ebenfalls nicht dargestellten) Serviceaggregates auf eine maschinenlange Kreuzspulentransporteinrichtung 21 übergeben werden.As is known, have such automatic packages 1 between their (not shown) Endgestellen a plurality of

Die einzelnen Arbeitsstellen 2 verfügen zu diesem Zweck, wie bekannt und daher nur angedeutet, über verschiedene Einrichtungen, die einen ordnungsgemäßen Betrieb dieser Arbeitstellen gewährleisten.For this purpose, the
Diese an sich bekannten Einrichtungen sind beispielsweise ein Spulstellenrechner 29, eine um eine Schwenkachse 16 bewegliche, unterdruckbeaufschlagbare Saugdüse 12, ein um eine Schwenkachse 13 bewegliches, unterdruckbeaufschlagbares Greiferrohr 11 sowie eine pneumatische Fadenspleißvorrichtung 10.These devices known per se are, for example, a winding
Die pneumatische Fadenspleißvorrichtung 10 ist bezüglich des regulären Fadenlaufes etwas zurückversetzt und mit ihrem Spleißergehäuse 31 am Spulstellengehäuse 33 festgelegt.The
Solche Fadenspleißvorrichtungen 10 verfügen, wie an sich bekannt und nachfolgend anhand der

In der Aufnahmeeinrichtung 30 sind Druckluftleitungen 27 festgelegt, deren Endstücke im Montagezustand mit entsprechenden Bohrungen im Verteilerkörper 17 des Spleißkopfes 18 korrespondieren.In the receiving
Das heißt, im Einbauzustand des Spleißkopfes 18 stehen die Druckluftleitungen 27 einerseits mit in den Spleißkanal 20 des Spleißprismas 19 mündenden Einblasöffnungen sowie anderseits mit den Aufnahmebohrungen 42 für die Halte- und Auflöseröhrchen 26A, 26B in Verbindung und sind über entsprechende Leitungen, in die zum Beispiel Elektromagnetventile eingeschaltet sind, an eine Druckluftquelle angeschlossen.That is, in the installed state of the

Auf dem Deckblech 22 ist, unter Zwischenschaltung eines O-Rings 40 ein Spleißprisma 19 befestigt, dessen druckluftbeaufschlagbarer Spleißkanal 19 ebenfalls jeweils garnspezifisch ausgebildet ist, das heißt, es ist zum Beispiel die Form des Spleißkanals und/oder die Anordnung und Ausbildung der im Spleißkanal mündenden Spleißluftdüsen auf ein bestimmtes Garnmaterial abgestimmt.On the
Am Spleißprisma 19 sind des Weiteren Fadenleitbleche 35A, 35B angeordnet, die dafür sorgen, dass die zu verbindenden Fadenenden ordnungsgemäß in den Spleißkanal 20 des Spleißprismas 19 gleiten.At the
Funktion der erfindungsgemäßen Fadenspleißvorrichtung:
- Wie bekannt, wird während des Spulbetriebes der laufende
Faden durch einen inFigur 1 lediglich schematisch dargestellten Fadenreiniger überwacht, der jede Fadenunregelmäßigkeit detektiert und anden Spulstellenrechner 29 meldet.Der Spulstellenrechner 29 initiiert daraufhin sofort einen definierten Fadenschnitt. Das heißt, durch eine Fadenschneideinrichtung wird der laufende Faden in einen Oberfaden und einen Unterfaden getrennt. Der Oberfaden läuft auf die Oberfläche der mit einem Bremsmoment beaufschlagten Kreuzspule 15 auf, während der Unterfaden in der Regel in einem Fadenspanner gehalten bleibt.
- As is known, during the winding operation of the current
Thread through one inFIG. 1 monitors only shown thread cleaner, which detects each Fadenunregelmäßigkeit and reports to the windingstation computer 29. The windingstation computer 29 then immediately initiates a defined thread cut. That is, by a thread cutting device of the current thread is separated into an upper thread and a lower thread. The upper thread runs on the surface of the applied with abraking torque cheese 15, while the lower thread is usually kept in a thread tensioner.
Zur Ausreinigung des schadhaften Fadenstückes sowie zur Erstellung einer neuen Fadenverbindung wird anschließend der auf die Kreuzspule 15 aufgelaufene Oberfaden wieder aufgenommen. Das heißt, die Saugdüse 12 wird nach oben geschwenkt und mit ihrer unterdruckbeaufschlagbaren Mündung im Bereich der Oberfläche der Kreuzspule 15 positioniert.
Gleichzeitig wird die Kreuzspule 15 langsam in Abwickelrichtung rotiert.To clean the defective thread piece and to create a new thread connection of the accrued to the
At the same time, the
Sobald die Saugdüse 12 den Oberfaden aufgenommen hat, wird mittels einer im Bereich der Saugdüse 12 angeordneten (nicht dargestellten) Fadenschneideinrichtung das schadhafte Fadenstück herausgetrennt und entsorgt.As soon as the
Anschließend wird der jetzt fehlerfreie Oberfaden durch die Saugdüse 12 in den Spleißkanal 20 des Spleißprismas 19 der Fadenspleißvorrichtung 10 eingefädelt, wobei der Faden auch durch die Trennbleche 34 und die Fadenleitbleche 35A und 35B geführt wird. Die Saugdüse 12 positioniert den Oberfaden 31 dabei auch in der oberen Fadenklemmeinrichtung 23A sowie zwischen den Werkzeugen der unteren Fadenschneideinrichtung 23B. Gleichzeitig oder etwas zeitversetzt zur Aufnahme des Oberfadens erfolgt auch die Aufnahme des Unterfadens.Subsequently, the now faultless upper thread is threaded through the
Das heißt, das Greiferrohr 11 holt den Unterfaden, der nach einem kontrollierten Fadenschnitt in der Regel in einem Fadenspanner festgelegt ist, am Fadenspanner ab und legt ihn ebenfalls in den Spleißkanal 20 des Spleißprismas 19 der Fadenspleißvorrichtung 10 ein.That is, the
Wie der Oberfaden wird auch der Unterfaden dabei in eine zugehörige untere Fadenklemmeinrichtung 23B sowie eine obere Fadenschneideinrichtung 23A eingefädelt.
Sobald die beiden Fäden in den Spleißkanal 20 eingelegt und in den Fadenklemmeinrichtungen 23A, 23B mechanisch fixiert sind, werden, durch entsprechendes Ansteuern eines Ventils, die Halte- und Auflöseröhrchen 26A, 26B mit Druckluft beaufschlagt und die Fäden durch die Fadenschneideinrichtungen 23A, 23B abgelängt.Like the upper thread, the lower thread is also threaded into an associated lower
As soon as the two threads are inserted into the
Die freien Fadenenden von Ober- und Unterfaden werden in die Halte- und Auflöseröhrchen 26A, 26B eingesaugt und durch die über Tangentialbohrungen in die Halte- und Auflöseröhrchen 26A, 26B einströmende Druckluft vorschriftsmäßig pneumatisch vorbereitet. Das heißt, die in die Halte- und Auflöseröhrchen 26A, 26B eingesaugten Fadenenden von Ober- und Unterfaden werden weitestgehend von ihrer Garndrehung sowie von Kurzfasern befreit.The free yarn ends of upper and lower thread are sucked into the holding and
Die vorbereiteten Fadenenden werden dann, wie bekannt und daher weder dargestellt noch näher erläutert, durch einen so genannten Schlaufenzieher in den Spleißkanal 20 des Spleißprismas 19 der Fadenspleißvorrichtung 10 gezogen und dort pneumatisch verbunden. Das heißt, der Spulstellenrechner 29 steuert über eine Signalleitung ein Elektromagnetventil so an, dass über eine der Druckluftleitungen 27 Spleißluft in den Spleißkanal 20 ein- geblasen wird, die die zunächst weitestgehend parallel angeordneten Fasern der beiden Fadenenden miteinander verwirbelt und dabei eine nahezu garngleiche Fadenverbindung herstellt.The prepared yarn ends are then, as known and therefore neither illustrated nor explained in more detail, pulled by a so-called loop puller in the
