Die Erfindung betrifft eine Ringspinnmaschine mit an einer gemeinsamen Tragstange befestigten, aufklappbaren Fadenführern zwischen Aüsgangswalzenpaar und Spinnringen mit Läufern und mit einer antreibbaren Aufwindetrommel, auf die ein Zuglied aufwindbar ist, das die Fadenführer-Tragstange schrittweise anhebt und sie beim Zurückdrehen in eine Tiefstellung absenkt.The invention relates to a ring spinning machine with attached to a common support rod, hinged thread guides between Aüsgangswalzenpaar and spinning rings with runners and with a drivable Aufwind drum, on which a Zuglied is aufwindbar that gradually lifts the thread guide support rod and lowers it when turning back into a low position.

Stand der TechnikState of the art

Die Fadenführer, mit denen Ringspinnmaschinen ausgestattet sind und die den Fadenballon nach oben begrenzen, sind individuell ausklappbar. Sie sind aber auch gemeinsam ausklappbar, um das Abziehen voller Kopse und das Aufstecken leerer Hülsen insbesondere mittels selbsttätiger Vorrichtungen beim Spulenwechsel zu gestatten. Sie sind zu diesem Zweck auf einer gemeinsamen Tragstange angeordnet, die um etwa eine Viertel Drehung nach hinten schwenkbar ist und dabei die Fadenführer aus der Achse der Spindeln heraus schwenkt.The thread guides, which are equipped with ring spinning machines and limit the thread balloon upwards, are individually foldable. But they are also foldable together to allow the removal of full cops and attaching empty pods in particular by means of automatic devices when changing the bobbin. They are arranged for this purpose on a common support rod, which is pivotable backwards by about a quarter turn while the thread guide pivots out of the axis of the spindles.

Das Verschwenken der Fadenführer-Tragstange erfolgt häufig von Hand. Es sind aber auch selbsttätige Vorrichtungen bekannt, die durch Arbeitselemente wie Elektromagnete, fluidisch beaufschlagbarer Kolben/Zylindereinheiten oder ähnliches betätigbar sind.The pivoting of the thread guide support rod is often done by hand. But there are also known automatic devices that can be actuated by working elements such as electromagnets, fluidically acted piston / cylinder units or the like.

Solche gesonderten Betätigungsvorrichtungen erfordern jedoch nicht nur gesonderte Einrichtungen, sondern auch gesonderte Steuervorrichtungen, um sie funktionsgerecht in Abhängigkeit von anderen Arbeitselementen und Arbeitsabläufen zu betätigen.However, such separate actuators require not only separate devices but also separate control devices to functionally operate them in response to other work items and operations.

In der DE 198 15 518 A1 ist eine Spinnvorrichtung mit Spindeln mit Spindelaufsatz zum ballonlosen Spinnen offenbart, bei der die Fadenführer an einer vertikal verschiebbaren Welle gemeinsam schwenkbar gelagert sind (Spalte 8 Zeilen 41/42). Zum Kopswechsel werden sie gemeinsam hochgeklappt.In the DE 198 15 518 A1 discloses a spinning device with spindles with spindle attachment for balloonless spinning, wherein the yarn guide on a vertically displaceable shaft are pivotally mounted together (column 8 lines 41/42). To change cop they are folded up together.

In der DE 198 26 525 A1 ist eine Vorrichtung offenbart, bei der die Welle der Fadenführungs-Tragstange mittels eines Motors schwenkbar ist. Dieser Motor erfordert eine gesonderte Steuervorrichtung.In the DE 198 26 525 A1 a device is disclosed in which the shaft of the thread guide support rod is pivotable by means of a motor. This engine requires a separate control device.

In der CH 370 683 sind der fadenführer und zwei Antiballonringe an einem gemeinsamen Träger angeordnet, der beim Hochfahren der den Träger enthaltenden Querglieder einem im Träger gelagerten Schieber gegen einen ortsfesten Anschöag fährt. Dadurch werden der Fadenführer und die Antiballonringe aus der Arbeiststellung nach oben geschwenkt.In the CH 370 683 the yarn guide and two antiballone rings are arranged on a common carrier, which drives a ramp mounted in the carrier against a stationary Anschöag at startup of the carrier-containing cross members. As a result, the thread guide and the anti-bounce rings are pivoted upwards from the working position.

Die DE-OS 24 25 434 offenbart eine Einrichtung, bei der die Fadenführer nach unten abgeschwenkt werden, um sie gemeinsam aus der Arbeitsstellung zu entfernen. Dieses Abschwenken erfolgt von Hand durch eine Handkurbel.The DE-OS 24 25 434 discloses a device in which the yarn guides are swung down to remove them together from the working position. This swinging is done by hand by a hand crank.

In Figur 1 ist das Ende des Spindelbereichs einer Ringspinnmaschine dargestellt. In einer Spindelbank 1 sind Spindeln gelagert, von denen nur eine mit aufgestecktem Kops 2 dargestellt ist, andere sind nur durch ihre Achse 3 angedeutet. Den Spindeln 3 ist eine Ringbank 4 zugeordnet, in der Spinnringe 5 mit Spinnläufern 6 befestigt sind.In FIG. 1 the end of the spindle range of a ring spinning machine is shown. In a spindle bank 1 spindles are stored, of which only one is shown with attached cop 2, others are indicated only by their axis 3. The spindles 3 is associated with a ring rail 4, are fixed in the spinning rings 5 with spinning rotors 6.

Oberhalb der Spindeln 3 sind Fadenführer 7 auf einer Fadenführerstange 8 angeordnet, die einzeln um etwa 90° nach oben aufklappbar sind. Die Fadenführer begrenzen die Spinnballone nach oben gegen das nicht dargestellte Streckwerk zu.Above the spindles 3 yarn guide 7 are arranged on a yarn guide rod 8, which are individually hinged by about 90 ° upwards. The yarn guides limit the spinning balloons up against the drafting system, not shown.

Ringbank 4 und Fadenführerstange 8 sind im Verlaufe des Spinnprozesses vertikal verlagerbar, um den Kops aufzubauen. Sie werden zu diesem Zweck durch Hubstangen 9 bzw. 10 getragen, die in einer Konsole 11 verschiebbar sind. An den unteren Enden der Hubstangen sind flexible Zugglieder 12 befestigt, die um ortsfest gelagerte Umlenkrollen 13 geführt sind. Die Bauteile 9 bis 13 sind entlang der Ringspinnmaschine mehrfach vorgesehen.Ring rail 4 and thread guide rod 8 are vertically displaceable in the course of the spinning process to build the Kops. They are supported for this purpose by lifting rods 9 and 10, which are displaceable in a bracket 11. At the lower ends of the lifting rods flexible tension members 12 are fixed, which are guided around fixedly mounted deflection rollers 13. The components 9 to 13 are provided several times along the ring spinning machine.

Die beiden Zugglieder 12 sind an weiteren Zuggliedern 14 befestigt, die sich über die ganze Länge der Ringspinnmaschine erstrecken und gleichmäßige Bewegung der Ringbank 4 und der Fadenführerstange 8 sicherstellen. Anstelle der Zugglieder 12 sind häufig Zugstangen vorgesehen. Die Zugglieder 12 sind über weitere Umlenkrollen 15 zu zwei Aufwindetrommeln 16, 17 geführt, die auf einer gemeinsamen Welle sitzen und über ein Getriebe 18 durch einen Elektromotor 19 antreibbar sind.The two tension members 12 are attached to further tension members 14, which extend over the entire length of the ring spinning machine and ensure uniform movement of the ring rail 4 and the thread guide rod 8. Instead of the tension members 12 tie rods are often provided. The tension members 12 are guided over further pulleys 15 to two Aufwindetrommeln 16, 17, which sit on a common shaft and are driven by a gear 18 by an electric motor 19.

Seitlich der größeren Aufwindetrommel 16 ist an dieser eine Nockenrolle 20 befestigt, die auf einen Schwenkhebel 21 einwirken kann. Am freien Ende dieses Schwenkhebels ist eine Zugstange 22 angelenkt, die nach oben zu einer ortsfest gelagerten Schwenkwelle 23 führt, an der sie über einen Arm 24 angreift. Die Schwenkwelle trägt auch einen Kulissenarm 25, in die sich ein am Ende der Fadenführerstange 8 angeordneter Kurbelarm 26 mit einem Kurbelzapfen 27 einlagern kann.Laterally of the larger winding drum 16, a cam roller 20 is attached to this, which can act on a pivot lever 21. At the free end of this pivot lever, a pull rod 22 is hinged, which leads upwards to a pivot shaft 23 fixedly mounted, on which it engages via an arm 24. The pivot shaft also carries a link arm 25, in which a arranged at the end of the thread guide rod 8 crank arm 26 can store with a crank pin 27.

Die Ringspinnmaschine ist in einer Stellung dargestellt, in der der Aufbau des Kopses 2 beendet ist und zum Wechsel gegen eine leere Hülse bereit steht. Durch Rückdrehen der Aufwindetrommeln 16, 17 durch den über die Maschinensteuerung entsprechend beaufschlagten Elektromotor 19 sind die Zugglieder 14 nachgelassen und haben über die Zweig-Zugglieder 12 sowohl die Ringbank 4 wie auch die Fadenführerstange 8 in deren tiefste Stellungen abgesenkt. Die Ringbank sitzt dabei auf der Spindelbank 1 auf, an der Fadenführerstange hat sich der Kurbelzapfen 27 in den Kulissenarm 25 eingelagert. Um ein weiteres Absenken der Fadenführerstange entlang der Ringspinnmaschine zu verhindern, kann das der Fadenführerstange zugeordnete Zugglied 14 ein Stoppglied 28 aufweisen, das sich an einen ortsfesten Anschlag 29 anlegt und dadurch die tiefste Stellung der Fadenführer 7 bestimmt.The ring spinning machine is shown in a position in which the structure of the cop 2 is finished and is ready to change against an empty sleeve. By turning back the Aufwindtrommeln 16, 17 by the machine control accordingly acted upon electric motor 19, the tension members 14 are lowered and have lowered over the branch tension members 12, both the ring rail 4 and the thread guide rod 8 in its lowest positions. The ring rail is seated on the spindle bank 1, on the thread guide rod, the crank pin 27 has been incorporated into the link arm 25. In order to prevent further lowering of the thread guide rod along the ring spinning machine, the tension member 14 associated with the thread guide rod may have a stop member 28 which abuts a stationary stop 29 and thereby determines the lowest position of the thread guide 7.

Bei weiterem Zurückdrehen der Aufwindetrommeln 16, 17 trifft die Nockenrolle 20 auf den Schwenkhebel 21 und drückt diesen nach unten. Über die Zugstange 22 wird dadurch die Schwenkwelle von der Fadenführerstange 8 aus gesehen im Uhrzeigersinne verdreht und schwenkt dabei die Kulisse 25 nach vorn. Dabei nimmt sie über den Zapfen 27 die Fadenführerstange mit und verschwenk dabei alle Fadenführer 4 nach oben. Damit nehmen sie die für das Auswechseln der Kopse 2 gegen leere Hülsen vorgesehenen Stellung ein.Upon further turning back the Aufwindtrommeln 16, 17, the cam roller 20 hits the pivot lever 21 and pushes it down. About the pull rod 22, the pivot shaft is thus seen from the thread guide rod 8 is rotated clockwise and thereby pivots the gate 25 forward. It takes over the pin 27 with the thread guide rod and thereby pivots all yarn guides 4 upwards. So they take the intended for the replacement of the cops 2 against empty sleeves position.

Das Aggregat Schwenkhebel 21, Zugstange 22, Schwenkwelle 23 ist - wie nicht in Einzelnen dargestellt - in dem Sinne feder- oder gewichtsbelastet, dass es sich dann, wenn die Aufwindetrommeln 16, 17 wieder vorwärts gedreht werden, um Ringbank 4 und Fadenführerstange 8 in die Ausgangslage für den Wiederanlauf der Ringspinnmaschine zu bringen, in ihre Ausgangslage zurück bewegen, sobald sich die Nockenrolle 20 vom Schwenkhebel 21 abhebt.The aggregate pivot lever 21, pull rod 22, pivot shaft 23 is - as not shown in detail - in the sense spring or weight-loaded, that when the Aufwindtrommeln 16, 17 are rotated forward again to ring rail 4 and thread guide rod 8 in the To bring starting position for the restart of the ring spinning machine, move back to its starting position as soon as the cam roller 20 lifts off the pivot lever 21.
