Description

Die Erfindung betrifft eine Fadenverbindungseinrichtung für eine Kreuzspulen herstellende Textilmaschine gemäß dem Oberbegriff des Anspruches 1.The invention relates to a thread connecting device for a cross-wound textile machine according to the Preamble of claim 1.

Derartige Fadenverbindungseinrichtungen sind beispielsweise durch die DE 195 10 171 A1 bekannt.Such thread connecting devices are, for example known from DE 195 10 171 A1.

Bei diesen Einrichtungen wird im Falle eines Fadenbruches oder bei einem Ablaufspulenwechsel über den Spulstellenrechner der betreffenden Spulstelle eine Fadenverbindungs- und/oder Kopswechselautomatik aktiviert. Das heißt, zunächst wird eine Saugdüse an die Oberfläche der langsam gegen die Wickelrichtung drehenden Auflaufspule angelegt. Nach dem Erfassen des Oberfadens schwenkt die Saugdüse in ihre Ausgangslage, in der die Ansaugdüsenöffnung unterhalb einer Spleißvorrichtung positioniert ist, zurück.In these facilities, in the event of a thread break or when changing the bobbin via the winding unit computer relevant winding unit a thread connection and / or Automatic cop change activated. That is, first one Suction nozzle to the surface of the slowly against the winding direction rotating spool. After capturing the Upper thread swings the suction nozzle into its starting position, in the the suction nozzle opening below a splicer is positioned back.

Nahezu gleichzeitig mit der Saugdüse schwenkt ein in einer unteren Ausgangslage positioniertes Greiferrohr in eine obere Arbeitsstellung und bringt dabei einen bis dahin z.B. in einem Fadenspanner gehaltenen, von der Ablaufspule abgezogenen Unterfaden mit.Almost simultaneously with the suction nozzle swings in one lower starting position positioned gripper tube in an upper Working position and brings you up to then e.g. in one Thread tensioner held, pulled off the payout spool Bobbin thread with.

Das Greiferrohr weist endseitig eine schwenkbar gelagerte, zum Beispiel federkraftbeaufschlagte Greiferrohrklappe mit einem Fadenverlegungshaken auf. Beim Hochschwenken schneidet das Greiferrohr mit dem Fadenverlegungshaken den Spannweg des Oberfadens, nimmt auch diesen Faden mit und positioniert ihn funktionsgerecht in der Spleißeinrichtung. Das heißt, die Greiferrohrklappe, die den Unterfaden während des Hochschwenkens des Greiferrohres mechanisch fixiert und mit ihrem Fadenverlegungshaken den Oberfaden mitnimmt, wird beim Einlaufen des Greiferrohres in die obere Endlage durch ein entsprechendes Kurvenstück etwas geöffnet, so daß die Fäden "gestrafft" in den Spleißer eingelegt werden.The end of the gripper tube has a pivoted, for Example of a spring-loaded gripper pipe flap with a Thread laying hook. That cuts when swiveling up Gripper tube with the thread laying hook the span of the Oberfadens, take this thread with you and position it functional in the splicer. That is, the Looper tube flap, which the lower thread during the Swiveling the gripper tube mechanically fixed and with her thread-laying hook takes the upper thread with her The gripper tube runs into the upper end position corresponding curve piece slightly opened so that the threads "tightened" in the splicer.

Nach dem Schnitt der Spleißerscheren wird das Reststück des Unterfadens durch das Greiferrohr abgesaugt. Anschließend schwenkt das Greiferrohr wieder in seine Ausgangslage zurück. Beim Herunterschwenken des Greiferrohres bleibt die an einem Kurvenstück geführte Greiferrohrklappe zunächst in einer Stellung in der die Mündung des Greiferrohres zumindest teilweise geöffnet ist. Die Greiferrohrklappe schließt das Greiferrohr erst nach Verlassen des Kurvenstückes unter der Wirkung des anstehenden Unterdruckes oder eines entsprechenden Federelementes.After cutting the splicing scissors, the remainder of the Aspirated through the looper tube. Subsequently swivels the gripper tube back into its starting position. When the gripper tube is swung down, it stays on one First, the gripper pipe flap guided in a curve is in one Position in the mouth of the gripper tube at least is partially open. The grab pipe flap closes that Gripper tube only after leaving the curve section under the Effect of the existing negative pressure or a corresponding one Spring element.

Nachteilig bei dieser Ausführungsform ist, daß die Gefahr besteht, daß, wenn es zu einem Fadenbruch oder zu einem Reinigerschnitt kommt, während die Greiferrohrklappe durch das Kurvenstück noch geöffnet ist, das Greiferrohr den Faden in der Abwärtsbewegung ansaugen kann. Wenn dann der Faden bei der nachfolgenden Fadenbruch- oder Reinigerschaltung unterhalb des Fadenspanners noch einmal angesaugt wird, kann es zu Umschlingungen an der Klappe des Greiferrohres kommen, was eine erhebliche Störung der Fadenverbindungseinrichtung bedeutet.The disadvantage of this embodiment is that the risk is that if there is a thread break or a Cleaner cut comes while the grapple flap goes through the Curve piece is still open, the hook tube the thread in the Can suck in downward movement. Then if the thread at the subsequent thread break or cleaner circuit below the Thread tensioner is sucked in again, it can Wraps around the flap of the gripper tube come what a significant disturbance of the thread connecting means.

Ausgehend vom vorgenannten Stand der Technik liegt der Erfindung daher die Aufgabe zugrunde, die bekannten Fadenverbindungseinrichtungen zu verbessern. Based on the aforementioned prior art, the The invention is therefore based on the object, the known To improve thread connecting devices.

Diese Aufgabe wird erfindungsgemäß durch eine Einrichtung gelöst, wie sie im Anspruch 1 beschrieben ist.This object is achieved by a device solved, as described in claim 1.

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

Bei der erfindungsgemäßen Ausführungsform wird die Greiferrohrklappe beim Hochschwenken beziehungsweise beim Herunterschwenken des Greiferrohres jeweils unterschiedlich geführt ist. Das hat den Vorteil, daß beim Hochschwenken des Greiferrohres in der Enlegephase des Fadens in den Spleißer die Greiferrohrklappe zunächst so geführt werden kann, daß die Klappe von der Greiferrohrmündung abgehoben wird. Die Fäden werden dabei gestrafft. Nach der Klemmung der Fäden im Spleißer wird die Greiferrohrklappe geschlossen. Bei der Abwärtsbewegung des Greiferrohres bleibt die Greiferrohrklappe geschlossen, so daß bei einem Fadenbruch/Anlaufschnitt der Faden nicht durch das Greiferrohr angesaugt werden kann.
Die Schließbewegung der Greiferrohrklappe wird dabei nicht nur durch den anstehenden Unterdruck erreicht, sondern auch durch die Anlage des Steuernockens der Greiferrohrklappe an der Gleitbahn des federbeaufschlagten Kurvenstückes der Steuerkulisse.In the embodiment according to the invention, the gripper tube flap is guided differently when the gripper tube is pivoted up or when it is pivoted down. This has the advantage that when the hook tube is swiveled up in the laying phase of the thread into the splicer, the hook tube flap can initially be guided such that the valve is lifted off the hook tube mouth. The threads are tightened. After the threads have been clamped in the splicer, the hook tube flap is closed. During the downward movement of the hook tube, the hook tube flap remains closed, so that the thread cannot be sucked in through the hook tube in the event of a thread break / start cut.
The closing movement of the gripper tube flap is not only achieved by the negative pressure present, but also by the control cam of the gripper tube flap resting on the slideway of the spring-loaded curve piece of the control link.

In vorteilhafter Ausgestaltung der Erfindung weist die Führungseinrichtung, wie im Anspruch 2 dargelegt, zwei separate Gleitbahnen auf, die nacheinander mit dem Steuernocken der Greiferrohrklappe korrespondieren.
Eine erste, gemäß Darstellung der Figuren 3a bis 3c, obere Gleitbahn sorgt dabei dafür, daß die Greiferrohrklappe beim Einschwenken des Greiferrohres in die Steuerkulisse durch den Steuernocken der Greiferrohrklappe von der Greiferrohrmündung abgehoben wird, während die zweite, untere Gleitbahn dafür sorgt, daß die Greiferrohrklappe beim Ausschwenken des Greiferrohres aus der Steuerkulisse stets geschlossen ist.In an advantageous embodiment of the invention, the guide device, as set out in claim 2, has two separate slideways which correspond in succession to the control cam of the gripper tube flap.
A first, as shown in Figures 3a to 3c, upper slideway ensures that the gripper tube flap is lifted from the gripper tube mouth by the control cam of the gripper tube flap when the gripper tube is pivoted into the control link, while the second, lower slideway ensures that the gripper tube flap is always closed when swiveling the gripper tube out of the control link.

Wie im Anspruch 3 dargelegt, besteht die Steuerkulisse im wesentlichen aus einem Grundkörper, der über einen Halter stationär am Spulstellengehäuse festgelegt ist, und einem am Grundkörper begrenzt beweglich gelagerten, federkraftbeaufschlagten Kurvenstück. Das Kurvenstück wird dabei durch das Federelement in einer vorgegebenen Grundstellung positioniert.As set out in claim 3, the control link consists in essentially from a basic body that has a holder is stationary on the bobbin case, and one on Basic body with limited movability, spring-loaded curve piece. The curve piece will thereby by the spring element in a predetermined Home position positioned.

Das Kurvenstück, das, wie im Anspruch 4 beschrieben, einen in den Schwenkweg des Greiferrohres reichenden die beiden separaten Gleitbahnen bildenden Steg aufweist, ist so gelagert, daß der Steuernocken der Greiferrohrklappe beim Hochschwenken des Greiferrohres nach außen abgelenkt und dadurch die Greiferrohrklappe etwas von der Greiferrohrmündung abgehoben wird. Beim Herunterschwenken des Greiferrohres, wenn der Steuernocken der Greiferrohrklappe an der zweiten Gleitbahn geführt ist, weicht das Kurvenstück der Steuerkulisse dem Steuernocken der Greiferrohrklappe aus, was dazu führt, daß die Greiferrohrklappe zusätzlich zum anstehenden Unterdruck auch noch durch das federkraftbeaufschlagte Kurvenstück beaufschlagt und dadurch jederzeit zuverlässig in Schließstellung gehalten wird.The curve piece, as described in claim 4, a in the two reach the swivel path of the gripper tube has separate web forming slideways, is mounted so that the control cam of the gripper tube flap when swiveling up deflected the gripper tube to the outside and thereby the The hook tube flap is lifted slightly from the hook tube mouth becomes. When swiveling down the gripper tube, if the Control cam of the hook tube flap on the second slideway is guided, the curve piece of the control link gives way to that Control cams of the gripper tube flap, which leads to the Grab pipe flap in addition to the negative pressure still acted upon by the spring-loaded curve piece and thus reliably held in the closed position at all times becomes.

Wie im Anspruch 5 beschrieben, besitzt das Greiferrohr im Bereich der Greiferrohrmündung eine Kerbe, durch die nach dem Schnitt der Spleißerscheren der Rest des Unterfaden entsorgt wird. Das heißt, durch diese Kerbe im Bereich der Greiferrohrmündung ist eine Entsorgung überschüssiger Fadenlänge auch dann gegeben, wenn die Greiferrohrklappe vollständig auf der Greiferrohrmündung aufliegt. As described in claim 5, the gripper tube has Area of the gripper tube mouth a notch through which after the Cut the splicers to dispose of the rest of the bobbin thread becomes. That is, through this notch in the area of Gripper pipe mouth is a disposal of excess Thread length is also given when the hook tube flap fully rests on the gripper pipe mouth.

Weitere Einzelheiten der Erfindung sind einem nachfolgend anhand der Zeichnungen erläuterten Ausführungsbeispiel entnehmbar.Further details of the invention are as follows exemplary embodiment explained with reference to the drawings removable.

Die Greiferrohrklappe 18 wird später, insbesondere anhand der Figuren 2 und 3, noch näher erläutert.As already indicated above, each winding unit 2 has a suction nozzle 12 and a gripper tube 25, which are each connected to a machine-long suction channel 37 via a suction air connection. The suction nozzle 12 is pivotally supported to a limited extent about an axis of rotation 16, the gripper tube 25 about an axis of rotation 26.
The gripper tube 25 also has a gripper tube flap 18 at its free end, which enables the gripper tube mouth 27 to be closed. The gripper tube flap 18 will be explained in more detail later, in particular with reference to FIGS. 2 and 3.

Wie insbesondere aus den Figuren 2 und 3 ersichtlich, ist die Greiferrohrklappe 18 ist um eine Schwenkachse 19 begrenzt drehbar gelagert. Im Bereich der Schwenkachse 19 kann zwischen dem Greiferrohr 25 und der Greiferrohrklappe 18 außerdem ein Federelement 53 eingeschaltet sein, das die Greiferrohrklappe 18 im Sinne "Schließen der Greiferrohrmündung 27" beaufschlagt.As can be seen in particular from FIGS. 2 and 3, the Gripper tube flap 18 is limited about a pivot axis 19 rotatably mounted. In the area of the pivot axis 19, between the gripper tube 25 and the gripper tube flap 18 also a Spring element 53 be turned on, which Gripper pipe flap 18 in the sense of "closing the Gripper tube mouth 27 "acted upon.

Wie insbesondere aus den Figuren 3a - 3c ersichtlich, weist die Greiferrohrklappe 18 an ihrer Frontplatte 65 einen nach vorne ragenden Fadenverlegungshaken 23 sowie zwischen dem Fadenverlegungshaken 23 und der Schwenkachse 19 eine Fadenführungseinrichtung auf. Die Fadenführungseinrichtung besteht dabei im wesentlichen aus einem in Greiferrohrschwenkrichtung S vorstehenden, nasenartigen Ansatz 61.As can be seen in particular from FIGS. 3a-3c, the Gripper pipe flap 18 on its front plate 65 forward protruding thread laying hook 23 and between the Thread laying hook 23 and the pivot axis 19 a Thread guide device. The thread guide device consists essentially of an in Gripper tube pivoting direction S protruding, nose-like Approach 61.

Die Greiferrohrklappe 18 verfügt des weiteren über einen Steuernocken 62, der in Verbindung mit einer im Bereich der oberen Endlage (II) des Greiferrohres 25 stationär angeordneten Steuerkulisse 33 ein definiertes Öffnen und Schließen der Greiferrohrklappe 18 ermöglicht.The gripper tube flap 18 also has a Control cam 62, which in connection with one in the area of Upper end position (II) of the gripper tube 25 arranged stationary Control link 33 a defined opening and closing of the Gripper pipe flap 18 allows.

Wie in den Figuren 3a bis 3c dargestellt, besteht die Steuerkulisse 33 aus einem Grundkörper 30, der über eine Halterung 51 zum Beispiel am Spulstellengehäuse 36 festgelegt ist, sowie einem über eine Schwenkachse 22 begrenzt beweglich mit dem Grundkörper 30 verbundenen Kurvenstück 34. Zwischen dem Grundkörper 30 und dem Kurvenstück 34 ist dabei ein Federelement 35, vorzugsweise eine Druckfeder, eingeschaltet. Das Federelement 35 sorgt dafür, daß das Kurvenstück 34 im unbeaufschlagten Zustand stets in der in Figur 3a dargestellten Grundstellung steht, in der sich das Kurvenstück 34 mit einem Anschlag 50 an der Halterung 51 abstützt. As shown in Figures 3a to 3c, there is Control link 33 from a base body 30, which has a Bracket 51, for example, fixed on the reel housing 36 is, and a limited movement over a pivot axis 22 curve piece 34 connected to the base body 30. There is between the base body 30 and the curve piece 34 a spring element 35, preferably a compression spring, switched on. The spring element 35 ensures that the Curve piece 34 in the unloaded state always in the in Figure 3a is the basic position shown, in which the Curve piece 34 with a stop 50 on the bracket 51 supported.

Das Kurvenstück 34 verfügt über einen zentralen Steg 47, dessen beiden Seitenflächen jeweils eine Gleitbahn 48 beziehungsweise eine Gleitbahn 49 bilden. Die Gleitbahnen 48 beziehungsweise 49 korrespondieren beim Einlaufen des Greiferrohres 25 mit einem Steuernocken 62 der Greiferrohrklappe 18.The curve piece 34 has a central web 47, the both side surfaces each have a slideway 48 or form a slideway 49. Slides 48 and 49, respectively correspond with a when the gripper tube 25 runs in Control cam 62 of the gripper pipe flap 18.

Funktion der Einrichtung:Function of the facility:

Bei einem Fadenbruch oder bei einem Reinigerschnitt ist der Unterfaden 55 in der Regel in einem nicht näher dargestellten Fadenspanner gehalten, während der Oberfaden 52 auf die Oberfläche der Kreuzspule 15 aufgelaufen ist.In the event of a thread break or a cleaner cut, this is Bobbin thread 55 usually in a not shown Thread tensioner held while the upper thread 52 on the Surface of the cheese 15 has accrued.

Das bedeutet, zunächst muß die Saugdüse 12 in die Nähe der Oberfläche der langsam gegen die Wickelrichtung umlaufenden Kreuzspule 15 gebracht und der Oberfaden 52 aufgenommen werden. Anschließend schwenkt die Saugdüse 12 in ihre untere Arbeitsposition (siehe Fig.2) und legt dabei den Oberfaden 52 in einen Reiniger, eine Schneideinrichtung sowie eine unterhalb der Spleißeinrichtung 10 angeordnete, geöffnete Klemm-und Schneidvorrichtung 17.That means, the suction nozzle 12 must first be close to the Surface of the slowly revolving against the winding direction Cross-wound bobbin 15 and the upper thread 52 are picked up. Then the suction nozzle 12 swings into its lower one Working position (see Fig. 2) and places the upper thread 52 into a cleaner, a cutter and one below the splicing device 10 arranged, open clamping and Cutting device 17.

Anschließend wird mittels des Greiferrohres 25 der Unterfaden 55 abgeholt. Das Greiferrohr 25 wird hierzu mit seiner Greiferrohrmündung 27 in einen Bereich knapp unterhalb des Fadenspanners geschwenkt und ergreift dort pneumatisch den Unterfaden 55. Ein an der Greiferrohrklappe 18 angeordneter Steuernocken 62 gleitet dabei über eine (nicht dargestellte) untere Steuerkulisse, so daß die Greiferrohrklappe 27 im Sinne "Aufschwenken Greiferrohrklappe 18" beaufschlagt wird.Then the gripper tube 25 Bobbin thread 55 picked up. The gripper tube 25 is used for this its gripper tube mouth 27 in an area just below of the thread tensioner swiveled and grips there pneumatically Bobbin thread 55. An arranged on the looper flap 18 Control cam 62 slides over a (not shown) lower control link, so that the gripper tube flap 27 in the sense "Swing open gripper pipe flap 18" is applied.

Beim Hochschwenken des Greiferrohres 25 schließt die Greiferrohrklappe 18 wieder und fixiert dadurch den Unterfaden 55 mechanisch. Auf seinem Weg in die obere Endlage II schneidet das Greiferrohr 22 mit seinem an der Greiferrohrklappe 18 angeordneten Fadenverlegungshaken 23 den Weg des Oberfadens 52 und nimmt diesen mit.When swiveling the gripper tube 25, the closes Gripper pipe flap 18 again and thereby fixes the Bobbin thread 55 mechanical. On its way to the upper end position II cuts the gripper tube 22 with his at the Gripper pipe flap 18 arranged thread laying hook 23 den Path of the upper thread 52 and takes it with it.

Wie in den Figuren 3a bis 3c angedeutet, korrespondiert der Steuernocken 62 der Greiferrohrklappe 18 beim Einlaufen in die Steuerkulisse 33 mit der Gleitbahn 48 des Kurvenstückes 34. Da sich das Kurvenstück 34 mit einem Anschlag 50 an der Halterung 51 abstützt, wird der Steuernocken 62 der Greiferrohrklappe 18 nach außen gedrückt und verschwenkt dabei die Greiferrohrklappe 18 in Richtung des Pfeiles R. Dieses Verschwenken der Greiferrohrklappe 18 führt nicht nur dazu, daß die Greiferrohrmündung 27 etwas geöffnet und der Unterfaden 55 unter der Wirkung des anstehenden Unterdruckes gestrafft wird, sondern führt auch zu einer Straffung des um den Fadenverlegungshaken 23 herumlaufenden Oberfadens 52. Das Verschwenken der Greiferrohrklappe 18 erfolgt dabei gegen den Druck des im Greiferrohr 25 anstehenden Unterdruckes sowie, wenn vorhanden, gegen die Federkraft eines Federelementes 53.As indicated in FIGS. 3a to 3c, the corresponds Control cam 62 of the gripper tube flap 18 when entering the Control link 33 with the slideway 48 of the curve piece 34. Since the curve piece 34 with a stop 50 on the Support bracket 51, the control cam 62 is the Gripper pipe flap 18 is pressed outwards and swiveled in the process the gripper tube flap 18 in the direction of arrow R. This Swiveling the gripper tube flap 18 not only leads to the fact that the hook tube mouth 27 is slightly opened and the lower thread 55 is tightened under the effect of the existing negative pressure, but also leads to a streamlining of the Thread laying hook 23 running upper thread 52. Das Swiveling the gripper tube flap 18 takes place against the Pressure of the negative pressure present in the gripper tube 25, and if present, against the spring force of a spring element 53.

Sobald der Steuernocken 62 der Greiferrohrklappe 18 die Gleitbahn 48 überfahren hat, schwenkt der Steuernocken 62 nach innen. Das heißt, die Greiferrohrmündung 27 wird bereits in dieser Endlage II des Greiferrohres 25 durch die Greiferrohrklappe 18 wieder sicher verschlossen.As soon as the control cam 62 of the gripper tube flap 18 Has passed slideway 48, the control cam 62 pivots Inside. That is, the gripper tube mouth 27 is already in this end position II of the gripper tube 25 through the Gripper pipe flap 18 securely closed again.

Beim anschließenden Herunterschwenken des Greiferrohres 25 gleitet der Steuernocken 62 an der zweiten Gleitbahn 49 entlang und verschwenkt dabei, wie in Figur 3c angedeutet, das Kurvenstück 34 der Steuerkulisse 33 in Richtung KS. Das zwischen dem Grundkörper 30 und dem Kurvenstück 34 der Steuerkulisse 33 eingeschaltete Federelement 35 beaufschlagt dabei den Steuernocken 62 der Greiferrohrklappe 18 zusätzlich mit einer Federkraft und gewährleistet, daß das Greiferrohr 25 beim Herunterschwenken durch die Greiferrohrklappe 18 bereits in diesem Bereich des Schwenkweges des Greiferrohres 25 stets sicher verschlossen ist.When the gripper tube 25 is subsequently pivoted down the control cam 62 slides along the second slideway 49 and pivots, as indicated in FIG. 3c, the Curve piece 34 of the control link 33 in the direction of KS. The between the base body 30 and the curve piece 34 of the Control link 33 acted upon spring element 35 the control cam 62 of the gripper tube flap 18 additionally with a spring force and ensures that the gripper tube 25th when swiveling down through the gripper tube flap 18 already always in this area of the swivel path of the gripper tube 25 is securely locked.
