Description

Die Erfindung betrifft eine Kettenwirkmaschine, insbesondere eine Häkelgalonmaschine, gemäss Oberbegriff des Anspruches 1.The invention relates to a warp knitting machine, in particular a crochet galloon machine, according to the preamble of claim 1.

Eine Kettenwirkmaschine, insbesondere Häkelgalonmaschine, der eingangs genannten Art ist beispielsweise in der DE-OS 3034253 beschrieben. Die Antriebsvorrichtung weist für jede Stange einen zugehörigen Exzenter auf, der an einer eigenen im Maschinengestell gelagerten Welle angeordnet ist. An jeder Welle ist überdies ein Zahnrad angebracht, über das ein für alle Wellen gemeinsamer Zahnriemen geführt ist, der die Verbindung zu einer gemeinsamen Antriebswelle herstellt. Der Hub der Stangen ist durch Einstellung der Exzentrizität der Exzenter individuell einstellbar. Durch die Vielzahl der Wellen mit entsprechenden Lagerstellen und Zahnrädern ist die Antriebsvorrichtung relativ kompliziert und kostspielig. Ausserdem beansprucht sie relativ viel Raum. Dennoch ist die Einstellung der innerhalb eines Gehäuses liegenden und sich gegenseitig behindernden Exzenter umständlich.A warp knitting machine, in particular crochet galloon machine, of the type mentioned at the outset is described, for example, in DE-OS 3034253. The drive device has an associated eccentric for each rod, which is arranged on its own shaft mounted in the machine frame. A gear is also attached to each shaft, through which a toothed belt common to all shafts is guided, which establishes the connection to a common drive shaft. The stroke of the rods can be individually adjusted by adjusting the eccentricity of the eccentrics. Due to the large number of shafts with corresponding bearing points and gear wheels, the drive device is relatively complicated and expensive. In addition, it takes up a relatively large amount of space. Nevertheless, the setting of the eccentrics lying within a housing and mutually obstructing is cumbersome.

Aufgabe der Erfindung ist es, eine Kettenwirkmaschine, insbesondere eine Häkelgalonmaschine, der eingangs genannten Art so auszubilden, dass sie in der Herstellung kostengünstiger und im Betrieb einfacher ist.The object of the invention is to design a warp knitting machine, in particular a crochet gallon machine, of the type mentioned at the outset in such a way that it is less expensive to manufacture and easier to operate.

Diese Aufgabe wird erfindungsgemäss durch die kennzeichnenden Merkmale des Anspruches 1 gelöst. Dadurch, dass sämtliche Stangen mit ihren Schwinghebeln und Pleuelstangen direkt von einer gemeinsamen Antriebswelle angetrieben werden, ergibt sich eine wesentliche Einsparung an Bauteilen und Raumbedarf, sodass die Antriebsvorrichtung einfacher, kostengünstiger und kompakter ausgebildet werden kann, wodurch sich auch die Zugänglichkeit und Handhabung verbessert.According to the invention, this object is achieved by the characterizing features of claim 1. The fact that all rods with their rocker arms and connecting rods are driven directly by a common drive shaft results in a substantial saving in components and space, so that the drive device can be made simpler, cheaper and more compact, which also improves accessibility and handling.

Vorteilhafte Ausgestaltungen der Kettenwirkmaschine sind in den Ansprüchen 2 bis 5 beschrieben.Advantageous embodiments of the warp knitting machine are described in claims 2 to 5.

Der Schwinghebel der Antriebsvorrichtung für die übrigen Schussführungen bzw. Fadenleger kann als einarmiger Hebel ausgestaltet sein, an dessen freiem Ende die Koppelstange zur Verbindung mit der hin-und hergehenden Stange angeschlossen ist. Dabei kann diese Koppelstange über einen Bolzen in einem Langloch befestigt sein. Vorteilhafter ist jedoch eine Ausbildung nach Anspruch 2, da dann die Einstellung der wirksamen Hebellänge an dem Arm erfolgen kann, der der Koppelstange abgewandt ist. Hierzu kann beispielsweise die mit der Antriebswelle verbundene Pleuelstange ebenfalls über einen Bolzen in einem Langloch des Schwinghebels befestigt sein. Bei der Ausbildung des Schwinghebels als zweiarmiger Schwinghebel ergibt sich weiter der Vorteil, dass das mit der Koppelstange zu verbindende Ende des Schwingarmes nach anderen Bedürfnissen ausgestaltet sein kann, insbesondere gemäss Anspruch 3. Dadurch ist ein Versetzen der Befestigungsstelle für die Koppelstange möglich, sodass die hin- und hergehende Stange in verschiedenen Führungen an den Schwingarmen der Kettenwirkmaschine eingesetzt werden kann.The rocker arm of the drive device for the remaining weft guides or thread layers can be designed as a one-armed lever, at the free end of which the coupling rod is connected for connection to the reciprocating rod. This coupling rod can be fastened in a slot by means of a bolt. However, an embodiment according to claim 2 is more advantageous, since the effective lever length can then be adjusted on the arm that faces away from the coupling rod. For this purpose, for example, the connecting rod connected to the drive shaft can also be fastened via a bolt in an elongated hole in the rocker arm. When the rocker arm is designed as a two-arm rocker arm, there is the further advantage that the end of the rocker arm to be connected to the coupling rod can be designed according to other requirements, in particular according to claim 3 - And forth rod can be used in various guides on the swing arms of the warp knitting machine.

Die Antriebsvorrichtung für die Langschussführungen sind zweckmässigerweise nach Anspruch 4 ausgebildet, wobei eine Weiterbildung nach Anspruch 5 von Vorteil ist.The drive device for the long-shot guides are expediently designed according to claim 4, a further development according to claim 5 being advantageous.

Die neuartige Ausbildung der Kettenwirkmaschine eignet sich insbesondere für die Herstellung einfacher Wirkwaren mit gleichbleibender Bindung, insbesondere zur Herstellung von Bändern mit eingewebten elastischen Fäden, wie Gummifäden.The novel design of the warp knitting machine is particularly suitable for the production of simple knitted fabrics with a constant weave, in particular for the production of tapes with woven-in elastic threads, such as rubber threads.

Die Figur 1 zeigt die an der Wirkstelle zusammenwirkenden Teile einer Häkelgalonmaschine analog der Ausbildung der Häkelgalonmaschine gemäss der DE-OS 27 58 421. An einem Balken 2 sind eine Reihe von Hakennadeln 4 angeordnet, die parallel zueinander liegen und nach vorne vorstehen. Die Hakennadeln 4 können in verschiedene Gruppen zusammengefasst sein. Die Hakennadeln werden in nicht näher dargestellter Weise in ihrer Längsrichtung hin- und hergehend bewegt. Am vorderen Bereich sind die Hakennadeln in Nut 6 eines Abschlagbalkens 8 geführt. Auf der den Hakennadeln 4 gegenüberliegenden Seite sind eine Reihe von Fadenführungen 10 angeordnet, die ebenfalls in einem Balken 12 gehalten sind, der eine hin- und hergehende Bewegung quer zur Richtung der Fadenführungen 10 ausführt, um jeweils einen zugeführten Kettfaden 14 an der zugehörigen Hakennadel 4 einzulegen. Beim Zurückgehen der Hakennadeln 4 wird eine auf der Hakennadel befindliche Masche abgeschlagen und eine neue Masche gebildet. Das Gewirk 16 wird nach unten abgeführt.FIG. 1 shows the parts of a crochet galloon machine interacting at the point of action analogous to the design of the crochet galloon machine according to DE-OS 27 58 421. A row of hook needles 4 are arranged on a bar 2, which are parallel to one another and protrude forward. The hook needles 4 can be combined in different groups. The hook needles are moved back and forth in their longitudinal direction in a manner not shown. At the front area, the hook needles are guided in the groove 6 of a tee 8. On the side opposite the hook needles 4, a series of thread guides 10 are arranged, which are also held in a bar 12 which executes a reciprocating movement transversely to the direction of the thread guides 10, in each case by a fed warp thread 14 on the associated hook needle 4 to insert. When the hook needles 4 retract, a stitch on the hook needle is knocked off and a new stitch is formed. The knitted fabric 16 is discharged downwards.

An der Wirkstelle sind weiter zwei Langschussführungen 18, 20 wirksam, die jeweils an Stangen 22, 24 befestigt sind, welche jeweils in einer Führung 26 eines Schwingarmes 28 hin- und hergehend verschieblich gelagert sind. Die Langschussführungen 18, 20 dienen jeweils zum Einlegen eines Schussfadens mindestens über einen Teil der Breite des Gewirks, um die einzelnen gewirkten Ketten miteinander zu verbinden. An der Wirkstelle stehen noch Fadenleger 30 im Einsatz, die ebenfalls an einer gemeinsamen Stange 32 befestigt sind, welche ebenfalls in einer Führung 26 des Schwingarmes 28 verschieblich gelagert ist. Der Fadenleger 30 dient im vorliegenden Beispiel zum Einwirken eines einzelnen Fadens längs einer gewirkten Kette des Gewirks. Der Schwingarm 28 wird mittels eines nicht näher dargestellten Antriebes um eine Achse 34 hin- und hergehend geschwenkt, um die Langschussführungen 18, 20 und die Fadenleger 30 in die jeweils erforderliche Stellung zur Abnahme der Fäden durch die Hakennadeln 4 zu bringen.At the point of action, two long-shot guides 18, 20 are also effective, each of which is fastened to rods 22, 24, which are each slidably mounted to and fro in a guide 26 of a swing arm 28. The long weft guides 18, 20 each serve to insert a weft thread at least over part of the width of the knitted fabric in order to connect the individual knitted chains to one another. At the place of action are still Thread layer 30 in use, which are also attached to a common rod 32, which is also slidably mounted in a guide 26 of the swing arm 28. In the present example, the thread layer 30 serves to act on a single thread along a knitted chain of the knitted fabric. The swing arm 28 is pivoted back and forth about an axis 34 by means of a drive, not shown, in order to bring the long-weft guides 18, 20 and the thread layer 30 into the respectively required position for removing the threads by the hook needles 4.

Die Figur 2 zeigt einen Ausschnitt aus einem Gewirk 16, welches mit einer Häkelgalonmaschine gemäss Figur 1 hergestellt werden kann. Die gewirkten Ketten 38 werden mittels der Hakennadeln 4 hergestellt. Die Langschussführungen 18, 20 dienen zum Einlegen von Schussfäden 40, welche die Verbindung zwischen den einzelnen gewirkten Ketten 38 herstellen. Im gezeigten Beispiel verläuft der Schussfaden lediglich zwischen zwei gewirkten Ketten 38, er kann jedoch aber auch über mehrere gewirkte Ketten verlaufen. Schliesslich ist in einer gewirkten Kette 38 ein Faden 42 eingewirkt, zu dessen Führung der Fadenleger 30 dient. Der Faden 42 ist beispielsweise ein elastischer Faden, insbesondere ein Gummifaden, wodurch sich ein hochelastisches Gewirk herstellen lässt.FIG. 2 shows a detail from a knitted fabric 16, which can be produced with a crochet galloon machine according to FIG. 1. The knitted chains 38 are produced by means of the hook needles 4. The long weft guides 18, 20 are used to insert weft threads 40, which establish the connection between the individual knitted chains 38. In the example shown, the weft thread only runs between two knitted chains 38, but it can also run over several knitted chains. Finally, a thread 42 is knitted in a knitted chain 38, the thread layer 30 serving to guide it. The thread 42 is, for example, an elastic thread, in particular a rubber thread, as a result of which a highly elastic knitted fabric can be produced.

Die Figuren 3 bis 7 zeigen die Antriebsvorrichtungen 44, 46 zum Antrieb der Langschussführungen 18, 20 und die Antriebsvorrichtung 48 zum Antrieb der Fadenleger 30. Eine gemeinsame Antriebswelle 50 ist über Kugellager 52, 54 in einem Gestell 56 drehbar gelagert. Die Antriebswelle 50 enthält ein Zahnrad 58, welches mittels eines Zahnriemens 60 angetrieben wird, der über ein angetriebenes Zahnrad 62 verläuft.FIGS. 3 to 7 show the drive devices 44, 46 for driving the long-shot guides 18, 20 and the drive device 48 for driving the thread layer 30. A common drive shaft 50 is rotatably mounted in a frame 56 via ball bearings 52, 54. The drive shaft 50 contains a toothed wheel 58 which is driven by means of a toothed belt 60 which runs over a driven toothed wheel 62.

An den Enden der Antriebswelle 50 sind jeweils Kurbelzapfen 64 eingeschraubt, die Pleuelstangen 66 tragen, welche an Schwinghebeln 68 angeschlossen sind.

Am anderen Ende der Schwinghebel sind jeweils Koppelstangen 72 angelenkt, welche mit Führungsgliedern 74 verbunden sind, an denen jeweils die Stangen 22, 24 angeschlossen sind. Jedes Führungsglied ist aus zwei Stäben 76 gebildet, die durch zwei Führungen 26 des Schwingsarmes 28 verlaufen und an den Enden über Verbindungsglieder 78 miteinander verbunden sind. Die Stäbe 76 dienen dazu, ein Verschwenken der Stangen zu verhindern. Die Koppelstangen 72 sind geteilt und mit hülsenförmigen Stellmuttern 80, die gegenläufige Gewindeteile aufweisen, zusammengehalten, um ihre Länge einstellen zu können. Ausserdem sind die Koppelstangen 72 jeweils mittels eines Gewindebolzens 82 und einer Feststellmutter 84 in einem Langloch 86 des Schwinghebels 68 befestigt, sodass die wirksame Länge des Schwinghebels 68 eingestellt werden kann.At the ends of the drive shaft 50 crank pins 64 are screwed in, which carry connecting rods 66, which are connected to rocker arms 68. At one end, the rocker arms 68 are rotatably mounted on an axis 70. Coupling rods 72 are articulated at the other end of the rocker arms, which are connected to guide members 74, to which the rods 22, 24 are connected. Each guide member is formed from two rods 76 which run through two guides 26 of the swing arm 28 and are connected to one another at the ends via connecting members 78. The rods 76 serve to prevent the rods from pivoting. The coupling rods 72 are divided and held together with sleeve-shaped adjusting nuts 80, which have opposing threaded parts, in order to be able to adjust their length. In addition, the coupling rods 72 are each fastened in a slot 86 of the rocker arm 68 by means of a threaded bolt 82 and a locking nut 84, so that the effective length of the rocker arm 68 can be adjusted.

Die Antriebsvorrichtung 48 für die Stange 32 der Fadenleger 30 wird gebildet aus einem Exzenterring 88, der zwischen den Kugellagern 52, 54 auf der Antriebswelle 50 befestigt ist.

A ball bearing 90 is arranged on this eccentric ring 88, on which the bearing ring 92 of a connecting rod 94 is fastened. The other end of the connecting rod 94 is connected to a two-armed rocker arm 96 which is rotatably mounted on the frame 56 via a pin 98. The arm 100 of the rocker arm 96 connected to the connecting rod 94 has an elongated hole 102, so that the connecting rod 94 can be adjusted in its effective lever length by means of a threaded bolt 104 and a locking nut 106.

Am anderen Arm 108 des Schwinghebels 96 ist eine Ausleger 110 angeordnet, an dem verschiedene Befestigungsstellen für einen Halter 112 einer Koppelstange 114 angeordnet sind. Die Koppelstange 114 ist wiederum mit einem Führungsglied 116 verbunden, an dem die Stange 32 für die Fadenleger 30 angeschlossen ist. Das Führungsglied ist wiederum entsprechend den Führungsgliedern 74 der Stangen 22, 24 der Langschussführungen 18, 20 ausgebildet. Ferner ist die Koppelstange 114 wiederum geteilt, wobei die einzelnen Teile mit gegenläufigen Gewinden versehen und mit einer entsprechenden Stellmutter 118 zusammengehalten sind, um die Länge der Koppelstange 114 einstellen zu können. Mit Hilfe der verschiedenen Befestigungsstellen am Ausleger 110 ist es möglich, die Stange 32 für die Fadenleger 30 an verschiedenen Führungen 26 des Schwingarmes 28 zum Einsatz zu bringen, wie dies strichpunktiert in den Figuren 4 und 7 angedeutet ist.On the other arm 108 of the rocker arm 96, a boom 110 is arranged, on which various fastening points for a holder 112 of a coupling rod 114 are arranged. The coupling rod 114 is in turn connected to a guide member 116 to which the rod 32 for the thread layer 30 is connected.
