Description

Die Erfindung betrifft eine Kettenwirkmaschine mit einer ersten Wirkwerkzeuganordnung, die eine Vielzahl von gleichartig bewegbaren ersten Wirkwerkzeugen aufweist, und einer zweiten Wirkwerkzeuganordnung, wobei die erste Wirkwerkzeuganordnung und die zweite Wirkwerkzeuganordnung während eines Maschenbildungszyklus relativ zueinander bewegbar sind, sich zumindest in einem Teil des Maschenbildungszyklus die ersten Wirkwerkzeuge an der zweiten Wirkwerkzeuganordnung abstützen und zweite Wirkwerkzeuganordnung Lamellen aufweist, zwischen denen Lamellengassen ausgebildet sind, in denen die ersten Wirkwerkzeuge zumindest in einem Teil des Maschenbildungsvorgangs angeordnet sind.The invention relates to a warp knitting machine with a first knitting tool arrangement, which has a plurality of first knitting tools that can be moved in the same way, and a second knitting tool arrangement, the first knitting tool arrangement and the second knitting tool arrangement being movable relative to one another during a stitch-forming cycle, the first knitting tool arrangement moving at least in part of the stitch-forming cycle Support knitting tools on the second knitting tool arrangement and the second knitting tool arrangement has lamellae between which lamellar lanes are formed, in which the first knitting tools are arranged at least in part of the stitch-forming process.

WO 03/056085 A1 beschreibt ein Verfahren und eine Anlage zur Herstellung eines mehrschichtigen, vorfixierten Faden- oder Fasergeleges. Die Anlage weist hierbei eine Maschenbildungsstelle auf, in der als Schiebenadeln ausgebildete Wirknadeln mit Schiebern zusammenwirken. Zusätzlich ist eine Stützbarre vorgesehen, die an ihrer der Ebene der Wirknadeln zugewandten Seite teilungsgerecht Führungsvorsprünge aufweisen, die die Schäfte der Wirknadeln seitlich führen können. WO 03/056085 A1 describes a method and a system for the production of a multi-layer, prefixed thread or fiber structure. In this case, the system has a stitch-forming point in which knitting needles designed as sliding needles interact with slides. In addition, a support bar is provided, which faces the plane of the knitting needles Page pitch fair have guide projections that can lead the shafts of the knitting needles laterally.

DE 32 41 154 A1 zeigt eine Kettenwirkmaschine mit einer ersten Wirkwerkzeuganordnung, die eine Vielzahl von gleichartig bewegbaren, an einer Barre befestigten Wirknadeln und eine Einschließ- und Abschlagplatinen aufweist, wobei die Wirknadeln und die Einschließ- und Abschlagplatinen während eines Maschenbildungszyklus relativ zueinander bewegbar sind und sich gegenseitig stützen können. DE 32 41 154 A1 shows a warp knitting machine with a first knitting tool arrangement, which has a plurality of similarly movable knitting needles attached to a bar and an enclosing and knocking-over sinker, wherein the knitting needles and the enclosing and knocking-over sinker are movable relative to one another during a stitch formation cycle and can support one another.

GB 191511969 A beschreibt eine Wirkmaschine mit Wirknadeln als erste Wirkwerkzeuganordnung, die mit Abschlagplatinen zusammenwirken. In den Abschlagplatinen ist jeweils ein Draht geführt, der verhindern soll, dass die Wirknadeln aus dem Raum zwischen den Abschlagplatinen hervortreten. Dies bedeutet, dass die Wirknadeln hier ebenfalls gegen einen Zug in Abzugsrichtung abgestützt sind, nicht jedoch gegen Kräfte, die parallel zur Längserstreckung einer Barre wirken. GB 191511969A describes a knitting machine with knitting needles as the first knitting tool arrangement, which interact with sinkers. A wire is guided in each sinker to prevent the knitting needles from protruding from the space between the sinkers. This means that the knitting needles are also supported here against a pull in the take-off direction, but not against forces that act parallel to the longitudinal extent of a bar.

EP 0 302 209 A1 zeigt eine Häkelgalonmaschine mit Wirknadeln und Schiebernadeln. Die Wirknadeln sind an einer Wirknadelbarre angeordnet. Die Schieber der Schiebernadeln sind an einer Schiebebarre befestigt. Ferner ist eine Abschlagschiene vorgesehen. EP 0 302 209 A1 shows a crochet machine with knitting needles and compound needles. The knitting needles are arranged on a knitting needle bar. The sliders of the compound needles are attached to a sliding bar. Furthermore, a knock-off rail is provided.

EP 2 770 097 A1 zeigt eine Kettenwirkmaschine zur Herstellung einer Schlingenware, bei der in einer Schieberbarre eine Vielzahl an Schiebern angeordnet ist. Die Schieber wirken mit Wirknadeln zusammen. Die Schieber haben unterschiedliche Höhen, so dass ein erster Satz von Maschen später als ein zweiter Satz von Maschen abgeworfen wird. EP 2 770 097 A1 shows a warp knitting machine for producing looped goods, in which a large number of slides are arranged in a slide bar. The sliders interact with knitting needles. The sliders are of different heights so that a first set of stitches will drop later than a second set of stitches.

Bei der Herstellung von Wirkwaren müssen mehrere Arten von Wirkwerkzeugen gleichartig bewegt werden. Gleichartige Wirkwerkzeuge sind hierzu an einer Barre, ggfs. auch an mehreren Barren angeordnet. Die Barren erstrecken sich in Breitenrichtung der Kettenwirkmaschine.In the production of knitted goods, several types of knitting tools have to be moved in the same way. Similar knitting tools are arranged on a bar, possibly also on several bars. The bars extend in the width direction of the warp knitting machine.

Während eines Maschenbildungszyklus werden Kettfäden, die beispielsweise in Form einer Fadenschar zulaufen, mit anderen Kettfäden verbunden, um eine textile Fläche auszubilden. Hierzu ist in der Regel eine seitliche Bewegung der Kettfäden erforderlich, die wiederum einen Zug auf Wirkwerkzeuge ausübt, der, in Abhängigkeit von der Höhe der wirkenden Kräfte, zu einer Verformung von Wirkwerkzeugen führen kann.During a knitting cycle, warp threads, which run in the form of a sheet of threads, for example, are connected to other warp threads to form a textile fabric. This generally requires a lateral movement of the warp threads, which in turn exerts a pull on the knitting tools, which, depending on the magnitude of the forces acting, can lead to a deformation of the knitting tools.

In gewissen Grenzen ist eine Verformung von Wirkwerkzeugen zulässig. Allerdings kann auch eine zulässige periodische Verformung von Wirkwerkzeugen zu erhöhten Beanspruchungen führen. Die Folgen derartiger Beanspruchungen umfassen u.a. Versagen und Verschleiß der Wirkwerkzeuge, Fehler in der Wirkware, nicht erreichbare Feinheiten und Produktivitätsverluste.Deformation of knitting tools is permissible within certain limits. Admittedly, a permissible periodic deformation of knitting tools can lead to increased stresses. The consequences of such stresses include failure and wear of the knitting tools, faults in the knitted fabric, unattainable gauges and loss of productivity.

Der Erfindung liegt die Aufgabe zugrunde, eine Kettenwirkmaschine mit einer hohen Produktivität bereitzustellen.The object of the invention is to provide a warp knitting machine with high productivity.

Diese Aufgabe wird bei einer Kettenwirkmaschine der eingangs genannten Art dadurch gelöst, dass. ein dem Arbeitsbereich benachbarter Einlaufbereich zwischen den Lamellen und den ersten Wirkwerkzeugen eine Spaltverbreiterung aufweist.This object is achieved in a warp knitting machine of the type mentioned at the outset in that an inlet area adjacent to the working area has a widened gap between the lamellae and the first knitting tools.

Mit einer derartigen Ausbildung kann man einer Verformung der ersten Wirkwerkzeuge in gewissen Grenzen entgegenwirken. Ein Wirkwerkzeug kann im vorliegenden Zusammenhang vereinfacht als Biegebalken angesehen werden, der mit einem Ende in einer entsprechenden Barre eingespannt ist. Außerhalb der Einspannung kann dieser Biegebalken verbogen werden. Wenn man nun außerhalb der Einspannung eine zusätzliche Abstützung durch die zweite Wirkwerkzeuganordnung vorsieht, dann kann diese Verbiegung klein gehalten werden. Wenn sich die ersten Wirkwerkzeuge an der zweiten Wirkwerkzeuganordnung abstützen, dann kommen die ersten Wirkwerkzeuge zur Anlage an die Lamellen. Man geht hierbei von der bisher vorliegenden Auffassung ab, dass ein Kontakt zwischen den ersten Wirkwerkzeugen und der zweiten Wirkwerkzeuganordnung vermieden werden sollte, sondern verwendet sogar ausdrücklich einen derartigen Kontakt, um eine Stütze für die ersten Wirkwerkzeuge zu bilden. Gegebenenfalls ist es sinnvoll, hier Maßnahmen zur Verminderung von Reibung zwischen den Wirkwerkzeugen zu treffen, beispielsweise eine reibungsvermindernde Schicht vorzusehen. Zwischen den ersten Wirkwerkzeugen und der zweiten Wirkwerkzeuganordnung ist, solange die ersten Wirkwerkzeuge nicht an der zweiten Wirkwerkzeuganordnung anliegen, ein kleiner Spalt vorgesehen. Dieser Spalt erlaubt ein verschleißarmes Zusammenwirken der ersten Wirkwerkzeuge mit der zweiten Wirkwerkzeuganordnung. Die Spaltverbreiterung ist eine Maßnahme, um zu vermeiden, dass in einer bestimmten Position, der so genannten "Auswurfposition" Fäden in dem Spalt geklemmt werden.With such a design, deformation of the first knitting tools can be counteracted within certain limits. In the present context, a knitting tool can be viewed in simplified terms as a bending beam that is clamped at one end in a corresponding bar. Outside of the clamping, this bending beam can be bent. If you now outside the clamping a provides additional support by the second knitting tool assembly, then this deflection can be kept small. When the first knitting tools are supported on the second knitting tool arrangement, the first knitting tools come to rest against the lamellae. This departs from the previously held view that contact between the first knitting tools and the second knitting tool arrangement should be avoided, but even explicitly uses such contact to form a support for the first knitting tools. It may be useful to take measures to reduce friction between the knitting tools, for example to provide a friction-reducing layer. A small gap is provided between the first knitting tools and the second knitting tool arrangement as long as the first knitting tools do not bear against the second knitting tool arrangement. This gap allows low-wear interaction of the first knitting tools with the second knitting tool arrangement. The widening of the gap is a measure to prevent threads from being jammed in the gap in a certain position, the so-called "ejection position".

In einer vorteilhaften Ausgestaltung weisen die ersten Wirkwerkzeuge jeweils einen Befestigungsbereich, mit dem sie an einer Barre befestigt sind, einen Arbeitsbereich und einen Übergangsbereich zwischen dem Befestigungsbereich und dem Arbeitsbereich auf, wobei die zweite Wirkwerkzeuganordnung mit dem Übergangsbereich zusammenwirkt. Der Arbeitsbereich wird also von einer Abstützung ausgenommen, so dass der Arbeitsbereich des entsprechenden Wirkwerkzeugs für seine eigentliche Aufgabe frei bleiben kann.In an advantageous embodiment, the first knitting tools each have a fastening area with which they are fastened to a bar, a working area and a transition area between the fastening area and the working area, with the second knitting tool arrangement interacting with the transition area. The working area is thus excluded from a support, so that the working area of the corresponding knitting tool can remain free for its actual task.

Vorzugsweise weist der Übergangsbereich eine größere Breite als der Arbeitsbereich auf. Der Übergangsbereich hat dementsprechend schon eine etwas größere Steifigkeit. Zusätzlich wirkt die Unterstützung durch die zweite Wirkwerkzeuganordnung einer Biegung entgegen.The transition area preferably has a greater width than the working area. The transition area already has one accordingly slightly more rigid. In addition, the support provided by the second knitting tool assembly resists deflection.

In einer bevorzugten Ausgestaltung kann die Spaltverbreiterung durch eine Fase an den Lamellen gebildet sein.In a preferred embodiment, the widening of the gap can be formed by a chamfer on the lamellae.

Alternativ oder zusätzlich kann auch vorgesehen sein, dass die Spaltverbreiterung durch eine Dickenveränderung der ersten Wirkwerkzeuge gebildet ist. In beiden Fällen ergibt sich eine im Schnitt etwa dreieckartige Verbreiterung des Spalts, bei der ein Klemmen der Fäden in einer Auswurfposition verhindert werden kann.Alternatively or additionally, it can also be provided that the widening of the gap is formed by a change in thickness of the first knitting tools. In both cases, there is an approximately triangular widening of the gap in the section, in which the threads can be prevented from becoming jammed in an ejection position.

Vorteilhafterweise sind die ersten Wirkwerkzeuge als Schiebernadeln und die zweite Wirkwerkzeuganordnung als Abschlagkammbarre oder als Wirkplatine ausgebildet. Die Abschlagkammbarre wird in einer Raschelmaschine verwendet, während die Wirkplatine mit praktisch gleicher Funktion in einem Kettenwirkautomat verwendet wird.Advantageously, the first knitting tools are designed as compound needles and the second knitting tool arrangement as a knock-over comb bar or as a sinker. The knock-over comb bar is used in a Raschel machine, while the knitting sinker is used in a warp knitting machine with practically the same function.

Die Erfindung wird im Folgenden anhand von bevorzugten Ausführungsbeispielen in Verbindung mit der Zeichnung beschrieben. Hierin zeigen:

Fig. 1 zeigt schematisch Teile einer Kettenwirkmaschine mit einer ersten Wirkwerkzeuganordnung 1, die eine Vielzahl von gleichartig bewegbaren ersten Wirkwerkzeugen aufweist. Die ersten Wirkwerkzeuge sind im vorliegenden Ausführungsbeispiel als Schiebernadeln ausgebildet. Die ersten Wirkwerkzeuge 1 weisen jeweils einen Befestigungsbereich 3 auf, mit dem sie an einer Barre 4 befestigt sind, einen Arbeitsbereich 5, der im vorliegenden Ausführungsbeispiel einen Nadelkopf 6 aufweist, und einen Übergangsbereich 7, der zwischen dem Befestigungsbereich 3 und dem Arbeitsbereich 5 angeordnet ist. 1 shows schematically parts of a warp knitting machine with a first knitting tool arrangement 1, which has a multiplicity of first knitting tools that can be moved in the same way. In the present exemplary embodiment, the first knitting tools are designed as compound needles. The first knitting tools 1 each have a fastening area 3, with which they are fastened to a bar 4, a working area 5, which has a needle head 6 in the present exemplary embodiment, and a transition area 7, which is arranged between the fastening area 3 and the working area 5 .

Mit Hilfe der Barre 4 werden alle ersten Wirkwerkzeuge 2 während eines Maschenbildungszyklus gleichartig bewegt.With the help of the bar 4, all the first knitting tools 2 are moved in the same way during a stitch formation cycle.

Mit den ersten Wirkwerkzeugen 2 wirkt eine zweite Wirkwerkzeuganordnung 8 zusammen. Die zweite Wirkwerkzeuganordnung 8 ist im vorliegenden Ausführungsbeispiel als Abschlagkammbarre ausgebildet. Eine Abschlagkammbarre wird in der Regel bei so genannten Raschelmaschinen verwendet. In einem Kettenwirkautomat kann anstelle der Abschlagkammbarre eine Wirkplatine verwendet werden.A second knitting tool arrangement 8 interacts with the first knitting tools 2 . In the present exemplary embodiment, the second knitting tool arrangement 8 is designed as a knock-over comb bar. A knock-off comb bar is usually used in so-called Raschel machines. In a warp knitting machine, a knitting board can be used instead of the knock-over comb bar.

Unabhängig davon ist die zweite Wirkwerkzeuganordnung 8 mit einer Vielzahl von Lamellen 9 ausgebildet. Zwischen den Lamellen 9 sind Lamellengassen 10 ausgebildet, in denen die ersten Wirkwerkzeuge 2 zumindest in einem Teil des Maschenbildungsvorganges angeordnet sind.Irrespective of this, the second knitting tool arrangement 8 is designed with a multiplicity of lamellae 9 . Lamella lanes 10 are formed between the lamellae 9, in which the first knitting tools 2 are arranged at least in part of the stitch-forming process.

Zwischen den ersten Wirkwerkzeugen 2 und den Lamellen 9 ist in diesem Fall ein Spalt 11 vorgesehen. Der Spalt 11 weist eine relativ kleine Dicke auf. Er muss nur so groß sein, dass die ersten Wirkwerkzeuge 2 sich frei in den Lamellengassen 10 bewegen können.In this case, a gap 11 is provided between the first knitting tools 2 and the lamellae 9 . The gap 11 has a relatively small thickness. It only has to be big enough for the first knitting tools 2 to be able to move freely in the lamella lanes 10 .

Dies gilt allerdings nur für den ungestörten Zustand. Sobald seitliche Kräfte auf den Arbeitsbereich 5 der ersten Wirkwerkzeuge 2 wirken, kann es zu einer Verformung der ersten Wirkwerkzeuge 2 kommen. Kräfte können beispielsweise von Fäden ausgeübt werden, die durch die ersten Wirkwerkzeuge 2 gehandhabt werden, genauer gesagt durch den Arbeitsbereich 5. Derartige Kräfte können insbesondere in einer Auswurfposition auftreten, wie sie in Fig. 1 dargestellt ist. Derartige Kräfte können parallel zur Längserstreckung der Barre 4 wirken. In diesem Fall können sich die ersten Wirkwerkzeuge 2 mit ihrem Übergangsbereich 7 an den Lamellen 9 der zweiten Wirkwerkzeuganordnung 8 abstützen. Wie man in Fig. 1 problemlos erkennen kann, wird dadurch eine freie Länge der ersten Wirkwerkzeuge 2, in der ein Verbiegen auftreten kann, ganz erheblich reduziert.However, this only applies to the undisturbed state. As soon as lateral forces act on the working area 5 of the first knitting tools 2, deformation of the first knitting tools 2 can occur. Forces can be exerted, for example, by threads that are handled by the first knitting tools 2, more precisely by the working area 5. Such forces can occur in particular in an ejection position, as is shown in 1 is shown. Such forces can act parallel to the longitudinal extent of the bar 4 . In this case, the first knitting tools 2 can be supported with their transition area 7 on the lamellae 9 of the second knitting tool arrangement 8 . how to get in 1 can easily see, a free length of the first knitting tools 2, in which bending can occur, is thereby reduced quite considerably.

In Fig. 1 ist mit "a" eine Teilung eingezeichnet, d.h. ein Mittenabstand der ersten Wirkwerkzeuge 2.In 1 a pitch is marked with "a", ie a center distance of the first knitting tools 2.

Die ersten Wirkwerkzeuge 2 haben jedenfalls im Bereich der Lamellengassen 10 eine Breite b. Die Lamellen 9 haben eine Breite c. Ferner ist ein Spalt s eingezeichnet. Die Dimensionierung einer derartigen Wirkwerkzeuganordnung ist nun so, dass a = b + c + 2s ist.In any case, the first knitting tools 2 have a width b in the area of the lamella lanes 10 . The slats 9 have a width c. Furthermore, a gap s is drawn. The dimensioning of such a knitting tool arrangement is such that a=b+c+2s.

In Fig. 1 ist erkennbar, dass der Übergangsbereich 7 eine größere Dicke oder Breite als der Arbeitsbereich 5 aufweist.In 1 it can be seen that the transition area 7 has a greater thickness or width than the working area 5 .

Wie man anhand von Fig. 2 und 3 erkennen kann, kann man den Übergangsbereich 7 weiterhin mit einem Dickenübergang ausgestalten, d.h. mit einer ersten Dicke in einem Bereich 12 und einer zweiten größeren Dicke in einem Bereich 13. Die zweiten Wirkwerkzeuge stützen sich dann mit dem Bereich größerer Dicke an den Lamellen 9 ab.How to based on Figures 2 and 3 As can be seen, the transition area 7 can also be configured with a transition in thickness, ie with a first thickness in an area 12 and a second greater thickness in an area 13. The second knitting tools are then supported on the lamellae 9 with the area of greater thickness.

Wie man durch einen Vergleich der Fig. 2 und 3 erkennen kann, kann man vorsehen, dass die ersten Wirkwerkzeuge 2 in der Auswurfposition an der zweiten Wirkwerkzeuganordnung 8 abgestützt sind, während sie in der Abschlagposition (Fig. 3) von der zweiten Wirkwerkzeuganordnung 8 frei gekommen sind. Dementsprechend wird der Abschlag der von den ersten Wirkwerkzeugen 2 gehandhabten Fäden durch die zweite Wirkwerkzeuganordnung 8 nicht behindert.How to by comparing the Figures 2 and 3 can be seen, it can be provided that the first knitting tools 2 are supported in the ejection position on the second knitting tool arrangement 8, while in the knock-off position ( 3 ) have come free from the second knitting tool assembly 8 . Accordingly, the second knitting tool arrangement 8 does not impede the knocking over of the threads handled by the first knitting tools 2 .

Für ein prozesssicheres Wirken ist es wichtig, dass in der in Fig. 2 dargestellten Auswurfposition keine Fäden zwischen den ersten Wirkelementen 2 und der zweiten Wirkelementanordnung 8 geklemmt werden.For process-reliable working, it is important that in the in 2 illustrated ejection position no threads between the first active elements 2 and the second active element arrangement 8 are clamped.

Fig. 4 und 5 zeigen zwei Möglichkeiten, wie man ein derartiges Klemmen verhindern kann. Beide Möglichkeiten können auch kombiniert miteinander eingesetzt werden. In beiden Ausgestaltungen ist eine Verbreiterung des Spalts 11 vorgesehen und zwar in einem Einlaufbereich 14, der dem Arbeitsbereich 5 benachbart ist. Figures 4 and 5 show two ways of preventing such jamming. Both options can also be used in combination with one another. In both configurations, the gap 11 is widened, specifically in an inlet area 14 which is adjacent to the working area 5 .

Bei der Ausgestaltung nach Fig. 4 weisen hierzu die Lamellen 9 eine Fase 15 auf, so dass sich an der dem Arbeitsbereich 5 zugewandten Seite der Lamellen 9 ein Spalt mit einer Breite s* ergibt, wobei s* ≥ s ist.When designing 4 For this purpose, the lamellae 9 have a chamfer 15, so that there is a gap with a width s* on the side of the lamellae 9 facing the working area 5, where s*≧s.

Bei der Ausgestaltung nach Fig. 5 ist die Spaltverbreiterung s* durch eine Dickenveränderung der ersten Wirkwerkzeuge 2 gebildet.When designing figure 5 the gap widening s* is formed by a change in thickness of the first knitting tools 2.
