Description

Kettenwirkmaschine, insbesondere Häkelgalonmaschine Warp knitting machine, in particular crochet galloon machine
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 gallon machine, according to the preamble of claim 1.
Eine Kettenwirkmaschine, insbesondere Häkelgalonmasch ine, der eingangs genannten Art ist beispielsweise in der DE-OS 27 58 421 beschrieben. Zum Antrieb der Stangen für die Langschussführungen dienen Schwinghebel, die an einer Seite des Maschinengestells angeordnet sind und über Exzenter angetrieben s i nd , w i e d i e s b e i s p i e l s w e i s e i n d e r D E -O S 27 21 024 bes chrieben ist. Diejenigen Stangen, die nicht zur Langschussführung dienen, sondern für Schussführungen anderer Art und/oder für Fadenleger, werden von Antriebsvorrichtungen betätigt, die auf der anderen Seite des Maschinengestells angeordnet sind. Zum Antrieb der Stangen sind also zwei Antriebe an verschiedenen Seiten des Maschinengestelles erforderlich, wodurch einerseits die Herstellung einer solchen Kettenwirkmaschine teuer ist und andererseits das Einstellen erschwert wird, da die Einstellung der Antriebsvorrichtungen an zwei verschiedenen Seiten des Maschinengestells vorgenommen werden muss.A warp knitting machine, in particular crochet gallon machine, of the type mentioned at the outset is described, for example, in DE-OS 27 58 421. Swing levers, which are arranged on one side of the machine frame and are driven by eccentrics, are used to drive the rods for the long-shot guides, and are described as well as described in the E-O S 27 21 024. Those rods, which are not used for long-shot guidance, but for other types of shot guidance and / or for thread-laying, are actuated by drive devices which are arranged on the other side of the machine frame. To drive the rods, two drives are therefore required on different sides of the machine frame, which on the one hand makes the manufacture of such a warp knitting machine expensive and on the other hand makes adjustment difficult because the adjustment of the drive devices must be carried out on two different sides of the machine frame.
Aufgabe der Erfindung ist es, eine Kettenwirkmaschine, insbesondere eine HakeIgalonmaschine, der eingangs genannten Art so auszubilden, dass sie in der Herstellung kostengünstiger und im Betrieb einfacher ist. Diese Aufgabe wird erfindungsgemäss durch die kennzeichnenden Merkmale des Anspruches 1 gelöst. Dadurch, dass auch die Antriebsvorrichtung für mindestens eine Stange für die Schussführungen und/oder Fadenleger auf der gleichen Seite des Maschinengestells angeordnet ist, wie die Antriebsvorrichtung für die Stangen der Langschussführungen und überdies mit diesen Antriebsvorrichtungen kombiniert ist, ergibt sich eine wesentliche Einsparung an Bauteilen und überdies ist das Einstellen der Antriebe einfacher, da sie von einer Seite aus erfolgen kann.The object of the invention is to design a warp knitting machine, in particular a hook-and-loop machine, of the type mentioned at the beginning in such a way that it is less expensive to manufacture and easier to operate. According to the invention, this object is achieved by the characterizing features of claim 1. The fact that the drive device for at least one rod for the weft guides and / or thread layer is arranged on the same side of the machine frame as the drive device for the rods of the long weft guides and moreover combined with these drive devices results in a substantial saving in components and moreover, it is easier to set the drives because they can be done from one side.
Vorteilhafte Ausgestaltungen der Kettenwirkmaschine sind in den Ansprüchen 2 bis 8 beschrieben.Advantageous embodiments of the warp knitting machine are described in claims 2 to 8.
Es wäre denkbar, dass für die Antriebsvorrichtung für die Stange der Schussführungen und/oder Fadenleger eine eigene Antriebswelle vorhanden ist, die mit der Antriebswelle der Antriebsvorrichtungen für die Stangen der Langschussführungen antriebsmässig verbunden ist. Vorteilhafter ist es jedoch, wenn die Antriebswelle für die Antriebsvorrichtungen der Langschussführungen gleichzeitig auch zum Antrieb der Antriebsvorrichtungen für die übrigen Schuss füh rungen und/oder Fadenleger verwendet wird. Eine besonders einfache und kompakte Bauweise ergibt sich, wenn die Kettenwirkmaschine nach Anspruch 2 ausgebildet ist. Der Schwinghebel der Antrebsvorrichtung für die übrigen Schussführungen und/oder Fadenleger kann mit einem Nachläufer ausgestattet sein, der unter Federvorspannung an dem Exzenter der Antriebswelle anliegt. Vorteilhafter ist jedoch eine Ausgestaltung nach Anspruch 4 da hier eine zwangsweise Führung des Schwinghebels in beiden Richtungen gegeben ist. Der Schwinghebel der Antriebsvorrichtung für die übrigen Schussführungen und/oder 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 5, da dann die Einstellung der wirksamen Hebellänge an dem Arm erfolgen kann, der der Koppelstange abgewandt ist. Hierzu kann beispielsweise eine 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 6. 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.It would be conceivable for the drive device for the rod of the weft guides and / or thread layer to have its own drive shaft, which is connected in terms of drive to the drive shaft of the drive devices for the rods of the long weft guides. However, it is more advantageous if the drive shaft for the drive devices of the long-shot guides is also used to drive the drive devices for the remaining weft guides and / or thread layers. A particularly simple and compact design results if the warp knitting machine is designed according to claim 2. The rocker arm of the anti-cancer device for the remaining weft guides and / or thread layers can be equipped with a follower which rests under spring tension on the eccentric of the drive shaft. However, an embodiment according to claim 4 is more advantageous since here the rocker arm is positively guided in both directions. The rocker arm of the drive device for the remaining weft guides and / or thread layer 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 5 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, a 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 6. This enables the fastening point for the coupling rod to be displaced, so that the - And forth rod can be used in various guides on the swing arms of the warp knitting machine.
Die Antriebsvorrichtungen für die Langschussführungen sind zweckmässigerweise nach Anspruch 7 ausgebildet, wobei eine Weiterbildung nach Anspruch 8 von Vorteil ist.The drive devices for the long-shot guides are expediently designed according to claim 7, a further development according to claim 8 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. Ein Ausführungsbeispiel der erfindungsgemässen Kettenwirkmaschine, insbesondere Häkelgalonmaschine, wird nachfolgend anhand von Zeichnungen näher beschrieben, dabei zeigen: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. An embodiment of the warp knitting machine according to the invention, in particular crochet galloon machine, is described in more detail below with reference to drawings, in which:

Die Figur 1 zeigt die an der Wirkstelle zusammenwirkenden Teile einer Häkelga lonmasch ine analog der Ausbildung der Häkelgalonmasch ine 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 zusammengef asst 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.1 shows the parts of a crochet knitting machine interacting at the point of action analogous to the design of the crochet knitting 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 grouped together 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 groove 6 of a knock-off bar 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 supplied 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 Lang-schussführungen 18, 20 wirksam, die jeweils an Stangen 22, 24 befestigt sind, welche jeweils in einer Führung 26 eines Schwingarmes 28 hinund 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 eben falls 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 Längsschussführungen 18, 20 und die Fadenleger 30 in die jeweils erforderliche Stellung zur Abnahme der F ä d en 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 knitting point, thread layers 30 are still in use if are 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 more detail) in order to bring the longitudinal 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 36, welches mit einer Häkelga lonmasch ine gemäss Figur 1 hergestellt werden kann. Die g'ewirkten Ketten 38 werden mittels der Hakennadeln 4 hergestellt. Die Längss chussfüh rungen 18 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 beispielsweiße ein elastischer Faden, insbesondere ein Gummifaden, wodurch sich ein hochelastisches Gewirk herstellen lässt.FIG. 2 shows a detail from a knitted fabric 36 which can be produced with a crochet yarn machine according to FIG. 1. The knitted chains 38 are produced by means of the hook needles 4. The longitudinal guiding 18 serve for inserting 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. An den Enden der Antriebswelle 50 sind jeweiIs KurbeIzapfen 64 eingeschraubt, die Pleuelstangen 66 tragen, welche an Schwinghebeln 68 angeschlossen sind. An einem Ende sind die Schwinghebel 68 an einer Achse 70 drehbar gelagert. 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 Fest stelImutter 84 in einem Langloch 86 des Schwinghebels 68 befestigt, sodass die wirksame Länge des Schwinghebels 68 eingestellt werden kann.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 layers 30. A common drive shaft 50 is rotatably mounted in a frame 56 via ball bearings 52, 54. The drive shaft 50 contains a gear 58, which is driven by means of a toothed belt 60, which runs over a driven gear 62. 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 by means of a threaded bolt 82 and a fixed nut 84 in an elongated hole 86 of the rocker arm 68, 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. An diesem Exzenterring 88 ist ein Kugellager 90 angeordnet, an dem der Lagerring 92 einer Pleuelstange 94 befestigt ist. Das andere Ende der Pleuelstange 94 ist mit einem zweiarmigen Schwinghebel 96 verbunden, der über einen Bolzen 98 am Gestell 56 drehbar gelagert ist. Der mit der Pleuelstange 94 verbundene Arm 100 des Schwinghebels 96 weist ein Langloch 102 auf, sodass die Pleuelstange 94 mittels eines Gewindebolzens 104 und einer Fest stelImutter 106 in seiner wirksamen Hebellänge einstellbar ist. 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 Längsführungen 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. The drive device 48 for the rod 32 of the thread layer 30 is formed from an eccentric ring 88, which is fastened between the ball bearings 52, 54 on the drive shaft 50. 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 fixed nut 106. 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. The guide member is in turn designed in accordance with the guide members 74 of the rods 22, 24 of the longitudinal guides 18, 20. Furthermore, the coupling rod 114 is again divided, the individual parts being provided with opposing threads and held together with a corresponding adjusting nut 118 in order to be able to adjust the length of the coupling rod 114. With the aid of the various fastening points on the arm 110, it is possible to use the rod 32 for the thread layer 30 on different guides 26 of the swing arm 28, as is indicated by dash-dotted lines in FIGS. 4 and 7.
