Description

Die Erfindung betrifft ein Streckwerk für Spinnmaschinen mit längs der Spinnmaschine verlaufenden Tragorganen für Stanzen und für Trag- und Belastungsarme.The invention relates to a drafting system for spinning machines with longitudinally extending the spinning frame support members for punching and for support and loading arms.

Die Erfindung geht aus von einem Streckwerk, wie es bspw. in Figur 2 der EP 1 375 708 dargestellt ist. Das Maschinengestell der betreffenden Spinnmaschine weist zwei neben-einander angeordnete, parallel verlaufende Tragstangen oder -rohre auf, auf die die Brückenstanzen der Streckwerke aufgesetzt sind. Die Brückenstanzen tragen die Streckwerke beider Maschinenseiten. In den Stanzen sind weitere Tragstangen befestigt, die die Belastungsarme tragen. Das Streckwerk weist demgemäß vier längs verlaufende Tragstangen oder -rohre auf.The invention is based on a drafting system, such as, for example, in FIG. 2 of the EP 1 375 708 is shown. The machine frame of the respective spinning machine has two juxtaposed, parallel support rods or tubes on which the bridge punches of the drafting systems are placed. The bridge punches carry the drafting systems on both sides of the machine. In the punching other support rods are attached, which carry the load arms. The drafting system accordingly has four longitudinal support rods or tubes.

Die Erfindung hatte sich die Aufgabe gestellt, den Aufbau eines derartigen Streckwerkes zu vereinfachen. Sie löst diese Aufgabe durch die im Kennzeichen des Hauptanspruches genannten Merkmale. Die erzielte Vereinfachung besteht in der Hauptsache in der Beschränkung auf nur zwei Tragorgane. Weitere Vorteile ergeben sich aus der nachfolgenden Beschreibung.The object of the invention has been found to simplify the construction of such a drafting system. It solves this problem by the features mentioned in the characterizing part of the main claim. The simplification achieved consists in the main in the restriction to only two supporting organs. Further advantages will become apparent from the following description.

In den Figuren der Zeichnung sind zwei Ausführungsbeispiele der Erfindung schematisch dargestellt. Es zeigen

  • Fig. 1 die perspektivische Ansicht einer ersten Ausführungsform;
  • Fig. 2 eine zweite Ausführungsform in Darstellung wie in Fig. 1.
In the figures of the drawing, two embodiments of the invention are shown schematically. Show it
  • Fig. 1 the perspective view of a first embodiment;
  • Fig. 2 a second embodiment in illustration as in Fig. 1 ,

Die Figuren zeigen Stanzen 1 und Trag- und Belastungsarme 2 eines Längsabschnittes der Streckwerke beider Maschinenseiten. Der Übersichtlichkeit halber sind die Unterwalzen und die Oberwalzen und weitere geläufige Arbeitsorgane der Streckwerke wie Luntentrichter, Riemchen und deren Führungsorgane usw. nicht dargestellt. Ebenso wenig sind die im Bereich 3 angeordneten Gelenke zum Hochschwenken der Trag- und Belastungsarme 2 eingezeichnet.The figures show punching 1 and supporting and loading arms 2 of a longitudinal section of the drafting of both sides of the machine. For the sake of clarity, the lower rollers and the upper rollers and other common working organs of the drafting systems such as Luntentrichter, straps and their management bodies, etc. are not shown. Nor are the joints arranged in the region 3 for pivoting up the support and loading arms 2 located.

In der Ausführungsform der Figur 1 sind zwei Tragrohre 4 und 5 vorgesehen, die parallel und übereinander von Zwischenständer zu Zwischenständer der Spinnmaschine verlaufen. Die Zwischenständer sind nicht dargestellt, am abgewendeten Ende des Streckwerksabschnittes ist einer der Halter 6 angedeutet, wie sie auf den Zwischenständern sitzen. Die Halter 6 weisen Bohrungen mit dem Durchmesser der Tragrohre 4 und 5 auf, in denen diese aufgenommen sind.In the embodiment of the FIG. 1 two support tubes 4 and 5 are provided, which extend parallel and one above the other from intermediate stand to intermediate stand of the spinning machine. The intermediate stands are not shown, at the averted end of the drafting section of the holder 6 is indicated as they sit on the intermediate stands. The holder 6 have holes with the diameter of the support tubes 4 and 5, in which they are accommodated.

Wie an der Stirnseite des dargestellten Streckwerksabschnittes erkennbar, sind die beiden jeweils einander gegenüber liegenden Stanzen 1 mit Ausnehmungen 7 versehen, die - gegeneinander gestellt - die Tragrohre 4 und 5 umgreifen. Die beiden Stanzen 1 sind durch nicht dargestellte Haltemittel wie Schrauben und Gewinde oder Muttern gegeneinander gedrückt und dadurch auf den Tragrohren festgeklemmt.As can be seen on the front side of the drafting section shown, the two respective opposing punches 1 are provided with recesses 7, which - set against each other - surround the support tubes 4 and 5. The two punches 1 are pressed by holding means, not shown, such as screws and threads or nuts against each other and thereby clamped on the support tubes.

In ähnlicher Weise sind im Bereich zwischen zwei im Abstand von acht Spinnstellen angeordneten Stanzen 1 auf beiden Seiten des Streckwerkes je vier Trag- und Belastungsarme 2 auf jeweils beiden Tragrohren 4 und 5 befestigt. Auch die Trag- und Belastungsarme 2 weisen zwei den Tragrohren zugeordnete Ausnehmungen 8 auf, mittels deren sie die Tragrohre umgreifen und auf ihnen festgeklemmt werden.Similarly, four support and loading arms 2 are mounted on each of the two support tubes 4 and 5 in the area between two punches 1 arranged at a distance of eight spinning positions on both sides of the drafting system. Also, the support and loading arms 2 have two the support tubes associated recesses 8, by means of which they embrace the support tubes and clamped on them.

In Bezug auf das vordere Ende des Streckwerks betrachtet wirken die Reaktionskräfte der über die Trag- und Belastungsarme 2 auf die Oberwalzen des vorn liegenden Streckwerkes ausgeübten Druckkräfte entgegen dem Uhrzeigersinn. Dagegen wirken die durch die Trag- und Belastungsarme 2 auf die Unterwalzen ausgeübten Druckkräfte im Uhrzeigersinn. Ein wesentlicher Vorteil dieser Anordnung besteht darin, dass diese beiden Kräfte über die beiden Tragrohre 4 und 5 in vorteilhafter Weise kurzgeschlossen sind.Viewed with respect to the front end of the drafting system, the reaction forces of the pressure forces exerted on the supporting and loading arms 2 on the top rollers of the front drafting system counterclockwise. In contrast, the compressive forces exerted by the support and loading arms 2 on the lower rollers act in a clockwise direction. A significant advantage of this arrangement is that these two forces are short-circuited over the two support tubes 4 and 5 in an advantageous manner.

In der Ausführungsform der Figur 2 sind die Tragorgane für die Stanzen 9 bzw. die Trag- und Belastungsarme 10 als zwei im Querschnitt im Wesentlichen quadratische oder rechteckige Tragkästen 11 und 12 ausgebildet. Diese Tragkästen 11, 12 bestehen vorteilhaft aus jeweils zwei gegeneinander gestellten U-Profilen 13, 14, die durch einen Deckel 15 und einen Boden 16 geschlossen sind. Am abgewendeten Ende des Streckwerksabschnittes ist einer der funktionell dem Halter 6 entsprechender Halter 17 angedeutet, wie sie auf den Zwischenständern sitzen und an denen die Tragkästen 11 und 12 befestigt sind.In the embodiment of the FIG. 2 are the support members for the punches 9 and the support and loading arms 10 as two in cross-section substantially square or rectangular support boxes 11 and 12 are formed. These support boxes 11, 12 are advantageously made of two mutually opposed U-profiles 13, 14, which are closed by a lid 15 and a bottom 16. At the averted end of the drafting section one of the functionally the holder 6 corresponding holder 17 is indicated, as they sit on the intermediate stands and where the support boxes 11 and 12 are fixed.

Es versteht sich, dass die Tragkästen 11 und 12 auch als gerollte Blechprofile ausgebildet sein können. Dass sie im Wesentlichen quadratisch oder rechteckig ausgebildet sind, bedeutet, dass sie gegebenenfalls in ihren Wandbereichen zum Erhöhen ihrer Steifigkeit bspw. auch Sicken aufweisen können.It is understood that the support boxes 11 and 12 may be formed as rolled sheet metal profiles. That they are formed substantially square or rectangular, means that they may optionally have in their wall areas to increase their rigidity, for example, corrugations.

Hier sind die Stanzen 9 im wesentlichen an den beiden Seitenwänden der unteren Tragkästen 12 befestigt, jedoch auch mit den oberen Tragkästen 11 verbunden. Sie stellen daher auch eine Verbindung zwischen den beiden Tragkästen 11 und 12 im Bereich zwischen den Haltern 17 dar. Das Befestigen erfolgt vorzugsweise durch Verschrauben, gegebenenfalls auch durch Verschweißen. Dadurch wird ein vorgefertigter, zumindest die Stanzen enthaltender Träger gebildet, an den die Trag- und Belastungsarme 2 im Werk oder an der Montagestelle anschraubbar sind.Here, the punches 9 are substantially attached to the two side walls of the lower support boxes 12, but also connected to the upper support boxes 11. They therefore also represent a connection between the two support boxes 11 and 12 in the region between the holders 17. The fastening is preferably carried out by screwing, possibly also by welding. As a result, a prefabricated, at least the punches containing carrier is formed, to which the support and loading arms 2 are screwed in the factory or at the mounting location.

Die Trag- und Belastungsarme 2, von denen auf den beiden Seiten des Streckwerkes unterschiedliche Ausführungsformen dargestellt sind, sind an den Seitenwänden der oberen Tragkästen 11 befestigt, vorzugsweise angeschraubt.The support and loading arms 2, of which different embodiments are shown on the two sides of the drafting system, are attached to the side walls of the upper support boxes 11, preferably screwed.
