Description

Die Erfindung betrifft eine für Strickmaschinen vorgesehene Zungennadel mit einer Nadelzunge, welche in einer Zungennut der Zungennadel schwenkbar gelagert ist und einen Zungenschaft, einen Zungenlöffel sowie einen Übergangsbereich zwischen dem Zungenschaft und dem Zungenlöffel aufweist.The invention relates to a provided for knitting machines latch needle with a needle tongue, which is pivotally mounted in a tongue groove of the latch needle and has a tongue shaft, a tongue spoon and a transition region between the tongue shaft and the tongue spoon.

Bei Zungennadeln von Strickmaschinen wird zum Öffnen und Schließen eines Hakenraums der Zungennadel eine Nadelzunge verwendet, die an einem Drehpunkt im Nadelschaft der Zungennadel gelagert ist. Diese Nadelzunge wird von der Masche betätigt, die sich entweder im Hakenraum der Zungennadel oder auf dem Nadelschaft hinter der Nadelzunge befindet.In tongue needles of knitting a tongue tongue is used to open and close a hook space of the latch needle, which is mounted at a pivot point in the needle shaft of the latch needle. This needle tongue is actuated by the mesh, which is located either in the hook space of the latch needle or on the needle shaft behind the needle tongue.

Zum Öffnen des Hakenraums zur Bildung einer neuen Masche wird die Zungennadel ausgetrieben. Dabei gleitet die sich im Nadelhaken befindende Masche auf einem Nadelhals der Zungennadel in Richtung des Nadelschafts. Durch diese Bewegung wird die Nadelzunge in ihre geöffnete Position geschwenkt. Anschließend gleitet die Masche über den Zungenschaft und über einen Zungenlöffel hinweg und gelangt dann vom Zungenlöffel auf den Nadelrücken.To open the hook space to form a new mesh, the latch needle is expelled. In this case, the mesh located in the needle hook slides on a needle neck of the latch needle in the direction of the needle shaft. This movement pivots the needle tongue to its open position. Then the stitch slides over the tongue shaft and over a tongue spoon and then passes from the tongue spoon to the back of the needle.

Zum Schließen des Hakenraums durch die Nadelzunge und zum Abwerfen der Masche wird die Zungennadel zurückgezogen, damit die Masche abgeworfen werden kann. Dabei gleitet die Masche, die sich auf dem Nadelrücken hinter der Nadelzunge befindet, in Richtung des Nadelhakens. Durch diese Bewegung schwenkt sie die Nadelzunge in ihre geschlossene Position. Bei weiterer Nadelbewegung gleitet die Masche über den Zungenschaft und den Zungenlöffel hinweg und gelangt über den Nadelhaken in ihren Maschenverband.To close the hook space through the needle tongue and to throw off the stitch, the latch needle is retracted so that the mesh can be dropped. The stitch, which is located on the back of the needle behind the needle tongue, slides in the direction of the needle hook. By this movement, it pivots the needle tongue in its closed position. Upon further needle movement, the stitch slides over the tongue shaft and the tongue spoon and passes over the needle hook in their mesh.

Bei einer Zungennadel gemäß dem Stand der Technik geschieht der Übergang vom Zungenschaft zum Zungenlöffel relativ plötzlich. Dadurch erfährt die Masche eine ruckartige Aufweitung, wenn sie vom Zungenschaft auf den Zungenlöffel gleitet, insbesondere bei geöffneter Nadelzunge, aber auch bei geschlossener Nadelzunge. Diese ruckartige Aufweitung der Masche bewirkt einen ruckartigen Anstieg der Fadenspannung, welche zum Platzen dieser Masche führen kann. Diesem Maschenplatzen kann nur durch Verminderung der Strickgeschwindigkeit entgegengewirkt werden. Dies ist ein besonders nachteiliger Aspekt, denn verminderte Strickgeschwindigkeit erhöht die Produktionszeit des Gestrickstücks.In a prior art latch needle, the transition from the tongue shaft to the tongue spoon occurs relatively suddenly. As a result, the stitch undergoes a sudden widening when it slides from the tongue shaft on the tongue spoon, especially when the needle tongue is open, but also when the needle tongue is closed. This jerky widening of the stitch causes a jerky increase in yarn tension, which can cause this stitch to burst. This mesh breaking can only be counteracted by reducing the knitting speed. This is a particularly disadvantageous aspect because reduced knitting speed increases the production time of the knit piece.

Ein Teil einer Zungennadel nach der Lehre des Stands der Technik ist in der Fig. 2 dargestellt. Die bekannte Zungennadel befindet sich in der geöffneten Position vergleichbar der erfindungsgemäßen Zungennadel gemäß Fig. 1d. Eine Nadelzunge 20 ist an einem Drehpunkt im Nadelschaft 21 schwenkbar gelagert. Ein Übergangsbereich 22 zwischen einem Zungenschaft 23 und einem Zungenlöffel 24 besitzt einen Brustbereich mit einer quer zur Längsrichtung der Zungennadel gesehenen Breite, welche identisch bezüglich der Breite des Rückenbereichs des Übergangsbereichs ist. Der Übergangsbereich 22 besitzt eine geringe Erstreckung und ist relativ abrupt ausgebildet.A part of a latch needle according to the teaching of the prior art is shown in FIG . The known latch needle is in the open position similar to the latch needle according to the invention shown in FIG. 1d. A needle tongue 20 is pivotally mounted at a pivot point in the needle shaft 21 . A transition region 22 between a tongue shaft 23 and a tongue spoon 24 has a breast region with a width seen transversely to the longitudinal direction of the latch needle, which is identical with respect to the width of the back region of the tongue Transition area is. The transition region 22 has a small extension and is relatively abrupt.

Der Erfindung liegt die Aufgabe zugrunde, den Gleitwiderstand der Masche im Übergangsbereich vom Zungenschaft zum Zungenlöffel zu verringern.The invention has for its object to reduce the sliding resistance of the mesh in the transition region from the tongue shaft to the tongue spoon.

Diese Aufgabe wird durch eine Zungennadel für eine Strickmaschine der eingangs genannten Art gelöst, bei welcher sich der Übergangsbereich von dem Austritt der Nadelzunge aus der Zungennut bei geschlossenem und/oder geöffnetem Hakenraum der Zungennadel bis zur Wand einer für einen Nadelhaken benötigten Auskehlung des Zungenlöffels erstreckt. Dieser verlängerte Übergangsbereich vergrößert die Anlagefläche der Masche zwischen dem Zungenschaft geringer Breite und dem breiteren Zungenlöffel und sorgt für einen sanften Übergang der Masche vom Zungenschaft zum Zungenlöffel.This object is achieved by a latch needle for a knitting machine of the type mentioned, in which the transition region extends from the exit of the needle tongue from the tongue groove with closed and / or open hook space of the latch needle to the wall of a required for a needle hook groove of the tongue spoon. This extended transition area increases the contact surface of the mesh between the tongue shaft of small width and the wider tongue spoon and ensures a smooth transition of the stitch from the tongue shaft to the tongue spoon.

Bei einer bevorzugten Ausführungsform verjüngt sich die Breite des Übergangsbereichs quer zur Längsrichtung der Nadelzunge ausgehend vom Zungenlöffel in Richtung des Zungenschafts. Die Anlagefläche für die Masche verbreitert sich vom Zungenschaft bis zur Breite des Zungenlöffels kontinuierlich, um einen plötzlichen Übergang zu vermeiden.In a preferred embodiment, the width of the transition region tapers transversely to the longitudinal direction of the needle tongue, starting from the tongue spoon in the direction of the tongue shaft. The contact surface for the mesh widens continuously from the tongue shaft to the tongue tongue width to avoid a sudden transition.

Zudem kann eine weitere Ausführungsform einen Zungenrücken mit einer quer zur Längsrichtung der Nadelzunge verlaufenden Breite des Übergangsbereichs aufweisen, welche gegenüber der entsprechenden Breite einer Zungenbrust des Übergangsbereichs geringer ist.In addition, another embodiment may have a tongue back with a transversely to the longitudinal direction of the needle tongue extending width of the transition region, which is smaller than the corresponding width of a tongue breast of the transition region.

Ein bevorzugtes Ausführungsbeispiel der Erfindung ist in der Zeichnung schematisch dargestellt und wird anhand der Figuren näher erläutert.A preferred embodiment of the invention is shown schematically in the drawing and is explained in more detail with reference to FIGS.

In den Fig. 1a bis 1d und Fig. 2 ist der bezüglich der Erfindung relevante Teil einer Zungennadel dargestellt, nämlich das Ende der Zungennadel, d.h. dort, wo eine Nadelzunge wirkt.In Figs. 1a to 1d and Fig. 2, the part of a latch needle relevant to the invention is shown, namely the end of the latch needle, i. where a needle tongue works.

Gemäß Fig. 1a weist eine Zungennadel 100 einen Nadelschaft 1, einen mit dem Nadelschaft 1 fest verbundenen Nadelhaken 2 und eine Nadelzunge 3 auf, welche an einem Drehpunkt 4 schwenkbar gelagert ist.According to FIG. 1 a, a latch needle 100 has a needle shaft 1, a needle hook 2 fixedly connected to the needle shaft 1, and a needle tongue 3 , which is pivotably mounted at a pivot point 4 .

Die Nadelzunge 3 umfasst einen Zungenschaft 5, einen Zungenlöffel 6 und einen Übergangsbereich 7 zwischen dem Zungenschaft 5 und dem Zungenlöffel 6. Der Übergangsbereich 7 ist auf beiden Seiten der Nadelzunge 3 identisch ausgebildet und erstreckt sich in Längsrichtung der Nadelzunge 3 zwischen einem Schaftende 8 und einem Löffelende 9 und quer zur Längsrichtung zwischen einer Zungenbrust 10 und einem Zungenrücken 11.The needle tongue 3 comprises a tongue shaft 5 , a tongue spoon 6 and a transition region 7 between the tongue shaft 5 and the tongue spoon 6. The transition region 7 is formed identically on both sides of the needle tongue 3 and extends in the longitudinal direction of the needle tongue 3 between a shaft end 8 and a Spout end 9 and transversely to the longitudinal direction between a tongue chest 10 and a tongue back 11th

Die Ränder des Übergangsbereichs 7 sind quer zur Längsrichtung durch die Zungenbrust 10 und den Zungenrücken 11 bestimmt und ergeben sich in Längsrichtung aus der Anordnung des Zungenlöffels 6 und der schwenkbaren Lagerung 4. Der Übergangsbereich 7 besitzt daher eine in Seitenansicht und in Draufsicht parallelogrammartige Form. Diese Form hat an der Zungenbrust 10 den Ausgangspunkt 12, an dem der Zungenschaft 5 bei geschlossener Nadelzunge aus einer Zungennut 19 austritt, und einen Endpunkt 13, der durch die Wandstärke einer Auskehlung 14 für den Nadelhaken 2 gegeben ist. An dem Zungenrücken 11 hat diese Form einen Ausgangspunkt 15 (Fig. 1c), an dem der Zungenschaft 5 bei geschlossener Nadelzunge aus der Zungennut 19 austritt, und einen Endpunkt 16, der wiederum durch die Wandstärke der Auskehlung 14 für den Nadelhaken 2 gegeben ist.The edges of the transitional region 7 are determined transversely to the longitudinal direction by the tongue breast 10 and the tongue back 11 and result in the longitudinal direction from the arrangement of the tongue spoon 6 and the pivotable mounting 4. The transition region 7 therefore has a parallelogram-like shape in side view and plan view. This form has at the tongue breast 10 the starting point 12 , at which the tongue shaft 5 emerges from a tongue groove 19 when the needle tongue is closed, and an end point 13 , which is given by the wall thickness of a groove 14 for the needle hook 2. At the tongue back 11, this shape has a starting point 15 (FIG. 1c), at which the tongue shaft 5 emerges from the tongue groove 19 when the needle tongue is closed, and an end point 16 , which in turn is given by the wall thickness of the groove 14 for the needle hook 2.

Aus der Fig. 1b ist ersichtlich, dass sich der Übergangsbereich 7 in seiner quer zur Längsrichtung der Nadelzunge 3 ausgebildeten Breite ausgehend von dem Löffelende 9 des Zungenlöffels 6 bis zur Breite des Zungenschafts 5 verjüngt. Der Übergangsbereich 7 weist einen Rückenbereich 17 mit einer geringeren Breite gegenüber einem Brustbereich 18 (siehe Fig. 1d) auf. Fig. 1b zeigt eine Ansicht des Zungenrückens der Nadelzunge 3, deren Zungenschaft 5 teilweise in der im Nadelschaft 1 ausgebildeten Zungennut 19 aufgenommen ist.From Fig. 1b it can be seen that the transition region 7 tapers in its transverse to the longitudinal direction of the needle tongue 3 formed width, starting from the spoon end 9 of the tongue spoon 6 to the width of the tongue shaft 5. The transition region 7 has a back region 17 with a smaller width than a breast region 18 (see FIG. 1 d ). 1b shows a view of the tongue back of the needle tongue 3, the tongue shaft 5 is partially received in the tongue groove 19 formed in the needle shaft 1.

Der Blick auf die Zungenbrust 10 gemäß Fig. 1d zeigt, dass der Übergang vom Zungenschaft 5 zum Zungenlöffel 6 auf der Seite der Zungenbrust 10 relativ flach verlaufend ausgebildet ist. In Fig. 1d ist der Übergangsbereich 7 durch strichpunktierte Linien nochmals deutlich herausgestellt.The view of the tongue breast 10 according to FIG. 1 d shows that the transition from the tongue shaft 5 to the tongue spoon 6 on the side of the tongue breast 10 is designed to be relatively flat. In Fig. 1d, the transition region 7 is again clearly shown by dotted lines.
