Description

Die Erfindung betrifft eine Kettenwirkmaschine mit einem Maschinengestell und mindestens zwei Legebarren, die Legenadeln tragen und in Versatzrichtung bewegbar sind, wobei eine Grundposition der Legebarren quer zur Versatzrichtung veränderbar ist.The invention relates to a warp knitting machine with a Machine frame and at least two guide bars, carry the guide needles and movable in the direction of displacement are, with a basic position of the guide bars across the Versatzrichtung is changeable.

Eine derartige Kettenwirkmaschine ist aus DE-PS 1 185 326 bekannt. Jede Legeschiene ist hierbei an mehreren Armen aufgehängt. Jeder Arm ist über ein Paar einseitig befestigte Bolzen an einem Tragarm befestigt, der wiederum auf einer Gehängwelle festgelegt ist. Ein Bolzen jedes Bolzenpaares ist zur Veränderung des seitlichen Legeschienenabstandes an seinem Arm exzentrisch drehbar und feststellbar angeordnet. Wenn der Abstand der Legenadeln geändert werden soll, dann muß man bei der entsprechenden Legebarre eine Änderung ihrer Winkellage vornehmen. Hierzu muß man an jedem Bolzen eine Mutter lösen, den Bolzen exzentrisch verdrehen und die Mutter dann wieder festziehen. Dies ist sehr aufwendig.Such a warp knitting machine is made of DE-PS 1 185 326 known. Each guide rail is here at several Poor hung. Each arm is over a pair one-sided fastened bolts attached to a support arm, which in turn is fixed on a suspension shaft. One Bolt of each pair of bolts is to change the lateral Guide rail distance on his arm eccentric arranged rotatable and lockable. When the distance the guide needles to be changed, then you have to the corresponding guide bar a change in their angular position make. For this one must at each bolt one Loosen the nut, turn the bolt eccentrically and remove the bolt Then tighten the nut again. This is very expensive.

Bei Wirkmaschinen mit zwei Wirknadelfonturen kann der Abstand der Nadelbarren verstellt werden, um bei einem Abstandsgewirke den Abstand zwischen den beiden Grundwarenbahnen vergrößern oder verringern zu können. Dadurch muß zumindest ein Teil der Legebarren dem geänderten Abstand der Arbeitsnadeln angepaßt werden, damit ein einwandfreies Zusammenwirken von Arbeitsnadeln und Lochnadeln beibehalten werden kann.In knitting machines with two knitting needles, the Distance of the needle bar be adjusted to one at Spacer knit the distance between the two Grundwarenbahnen increase or decrease. Thereby At least a part of the guide bars must be changed Distance of the working needles to be adjusted so a perfect cooperation of working needles and Hole needles can be maintained.

Die Legebarren sind vielfach an Legebarrenhebeln befestigt, die wiederum auf Gehängewellen geklemmt werden. Die Gehängewellen sind mit Lagerböcken an einer oder mehreren Traversen im Maschinengestell befestigt. Die Legebarrenhebel sind mit Legebarrenführungen versehen, in welchen die Legebarren aufgenommen werden. Die Legebarren führen zum Zweck der Musterung einen seitlichen Versatz parallel zur Arbeitsbreite durch. Weiterhin führen die Legebarren in der Regel eine Durchschwingbewegung während des Wirkprozesses durch. Dabei schwingen die an den Legebarren befestigten Lochnadeln durch die Gassen der Arbeitsnadeln. Die Durchschwingbewegung wird vielfach von einem Exzenter- oder Kurbeltrieb herbeigeführt, der sich im Maschinengestell befindet. Durch einen Stößel wird ein Maschinenhebel angesteuert, der mit mehreren Bohrungen versehen ist. Ein Gestänge verbindet den Maschinenhebel mit einem Ansteuerhebel, der auf die Gehängewelle geklemmt ist. Um die Grundposition der Legebarre und damit den Abstand der Legebarren zu verändern, kann das Verbindungsgestänge in eine von mehreren Bohrungen des Maschinenhebels gesteckt werden. Da in der Regel mehrere dieser Hebel auf der gesamten Arbeitsbreite der Kettenwirkmaschine verteilt sind, ist eine Abstandsverstellung der Legebarre auch hier sehr aufwendig.The guide bars are often attached to guide bar levers, which in turn are clamped on hanger shafts. The hanger shafts are with bearing blocks at one or several trusses mounted in the machine frame. The Leebarrenhebel are provided with guide bar guides, in which the guide bars are received. The guide bars lead for the purpose of patterning a lateral Offset parallel to the working width. Farther lead the guide bar usually a swinging motion during the active process. Swinging the needles attached to the guide bars through the Alleys of the working needles. The Durchschwingbewegung is often caused by an eccentric or crank drive, which is located in the machine frame. Through a Tappet is controlled by a machine lever, which with is provided with several holes. A linkage connects the machine lever with a control lever on the Hanging shaft is clamped. To the basic position of the guide bar and thus to change the distance of the guide bars, The linkage can be in one of several Drill holes of the machine lever are inserted. Because in usually several of these levers on the entire working width the warp knitting machine is distributed is a distance adjustment of the guide bar here too consuming.

Der Erfindung liegt die Aufgabe zugrunde, die Einstellung der Grundposition der Legebarren auf einfache Weise durchzuführen.The invention is based on the object, the setting the basic position of the guide bars in a simple manner perform.

Diese Aufgabe wird bei einer Kettenwirkmaschine der eingangs genannten Art dadurch gelöst, daß mindestens eine Legebarre an einem im Maschinengestell quer zur Versatzrichtung verlagerbaren Träger angeordnet ist, der durch einen Zentralantrieb positionierbar ist.This object is in a warp knitting machine of mentioned type achieved in that at least a guide bar on one in the machine frame across the Offset direction is arranged movable carrier, which can be positioned by a central drive.

Über die Positionierung des Trägers läßt sich die Grundposition der Legebarre verändern. Diese Positionierung des Trägers läßt sich quasi mit einer einzigen Aktion durchführen, weil lediglich der Zentralantrieb in Betrieb genommen werden muß. Der Zentralantrieb wirkt auf den Träger insgesamt, so daß man mit relativ geringem Aufwand eine Verlagerung des Trägers näher zur Versatzrichtung bewirken kann. Durch eine derartige Verlagerung wird die Grundposition der Legebarre geändert. Damit kann auf einfache Weise die Grundposition der entsprechenden Legebarre an veränderte Positionen der Wirknadeln angepaßt werden.About the positioning of the carrier can be the Change the basic position of the guide bar. This positioning of the wearer can be quasi with a single Perform action because only the central drive must be put into operation. The central drive acts on the carrier overall, so that with relative little effort a shift of the carrier closer to Can cause misalignment. By such Shifting is changed the basic position of the guide bar. This can easily the basic position the corresponding guide bar to changed positions the knitting needles are adapted.

Vorzugsweise ist der Träger als Traverse ausgebildet, die auf mindestens zwei Schlitten montiert ist, die auf Führungsschienen verschiebbar sind. Die Schienen verlaufen dann quer zur Versatzrichtung, also quer zur Arbeitsbreite der Kettenwirkmaschine. Wenn diese Schienen mit einem ausreichenden Abstand zueinander angeordnet sind, dann kann man die Ausrichtung der Traverse mit hoher Genauigkeit parallel zur Versatzrichtung beibehalten. Die Schlitten stellen dabei im Zusammenwirken mit den Schienen eine reibungsarme Bewegungsmöglichkeit für die Traverse zur Verfügung. Der Zentralantrieb kann also vergleichsweise schwach ausgebildet sein.Preferably, the carrier is designed as a crossbeam, which is mounted on at least two carriages on Guide rails are displaced. The rails run then across the offset direction, ie across the working width the warp knitting machine. If these rails arranged with a sufficient distance from each other then you can align the traverse with it maintain high accuracy parallel to the offset direction. The carriages interact with each other with the rails a low-friction movement available for the traverse. The central drive can so be comparatively weak.

Vorzugsweise sind zwei Legebarren an jeweils einem Träger angeordnet, wobei die Träger durch den Zentralantrieb gegensinnig bewegbar sind. Eine derartige Ausgestaltung ist insbesondere bei doppelfonturigen Kettenwirkmaschinen von erheblichem Vorteil, die ein Abstandsgewirke herstellen. Hier werden bei einer Veränderung des Abstands des Abstandgewirkes die Arbeitsnadeln ebenfalls gegensinnig verstellt. Wenn man nun die Legenadeln entsprechend gegensinnig verstellen kann, dann wird eine Anpassung der Grundposition der Legenadeln an die Arbeitsnadelfontur vereinfacht. Durch die Ansteuerung des Zentralantriebes lassen sich dann zwei Legebarren gleichzeitig positionieren. Diese Positionierung erfolgt so, daß vorgegebene Randbedingungen automatisch eingehalten werden, beispielsweise eine symmetrische Anordnung der Legebarren.Preferably, two guide bars are each on a carrier arranged, with the carrier through the central drive are movable in opposite directions. Such a design is especially in double-ended warp knitting machines of considerable advantage being a spacer knit produce. Here will be a change the distance of the spacer knit the working needles also adjusted in opposite directions. If you now the Guide needles can adjust accordingly in opposite directions, then an adjustment of the basic position of the guide needles simplified to the working needle contour. By the Control of the central drive can then be two Position guide bars at the same time. This positioning done so that the given boundary conditions automatically be complied with, for example, a symmetrical Arrangement of the guide bars.

Bevorzugterweise weist der Zentralantrieb mindestens eine Gewindespindel auf, die in eine Gewindebuchse am Träger eingreift und zumindest in Richtung ihrer Längserstreckung ortsfest am Maschinengestell gehalten ist. Durch eine Drehbewegung der Gewindespindel in eine Richtung wird der Träger in eine erste Richtung verlagert. Wenn die Gewindespindel in die andere Richtung gedreht wird, dann wird der Träger in die entgegengesetzte Richtung verlagert. Da mit einer derartigen Gewindepaarung zwischen Gewindespindel und Gewindebuchse ein relativ großes Übersetzungsverhältnis verbunden ist, ist es einerseits möglich, die entsprechende Legebarre relativ genau zu positionieren. Andererseits ist für die Verlagerung der Legebarre mit ihrem Träger nur eine vergleichsweise geringe Kraft erforderlich.Preferably, the central drive at least a threaded spindle, which in a threaded bushing on Carrier engages and at least in the direction of its longitudinal extent is held stationary on the machine frame. By a rotary movement of the threaded spindle in one Direction, the carrier is displaced in a first direction. When the threaded spindle in the other direction is rotated, then the carrier is in the opposite Shifted direction. Because with such a thread pairing between threaded spindle and threaded bush a relatively large gear ratio connected is, on the one hand it is possible, the appropriate Legebarre to position relatively accurately. On the other hand for the relocation of the delivery cart with its carrier only a comparatively small force is required.

Vorzugsweise weist die Gewindespindel zwei gegenläufig gerichtete Gewindeabschnitte auf, die in Gewindebuchsen an den Trägern mit entsprechend entgegengesetzt gerichteten Gewinden eingreifen. Wenn die Gewindespindel in eine Richtung gedreht wird, dann werden die beiden Träger aufeinander zu bewegt, so daß sich der Abstand der Legebarren verringert. Wenn die Gewindespindel in die andere Richtung gedreht wird, dann wird der Abstand zwischen den Trägern und den damit verbundenen Legebarren entsprechend vergrößert.Preferably, the threaded spindle has two opposite directions directed threaded sections in threaded bushes on the carriers with accordingly oppositely directed Engage threads. When the threaded spindle in one direction is turned, then the two carriers moved towards each other, so that the distance of the Legebarren reduced. When the threaded spindle in the the other direction is turned, then the distance between the carriers and the associated guide bars increased accordingly.

Vorzugsweise ist die Gewindespindel in einer im Maschinengestell fixierten Haupttraverse gelagert. Die Haupttraverse dient dann als Festanschlag und Fixpunkt.Preferably, the threaded spindle is in a machine frame stored fixed main beam. The main crossbar then serves as a fixed stop and fixed point.

Hierbei ist von Vorteil, wenn in Versatzrichtung verteilt mindestens zwei Gewindespindeln angeordnet sind, die über Verbindungsmittel synchron miteinander gekuppelt sind. Derartige Verbindungsmittel können beispielsweise Zahnräder oder Ketten sein, wobei sichergestellt ist, daß die Drehung einer Gewindespindel unmittelbar auf eine oder mehrere andere Gewindespindeln übertragen wird. Damit ist es möglich, den zur Abstützung der Legebarre verwendeten Träger in Breitenrichtung der Kettenwirkmaschine an mehreren Positionen mit Kraft zu beaufschlagen, um eine Verlagerungsbewegung zu bewirken. Damit wird das Risiko klein gehalten, daß der Träger bei einer Ansteuerung durch den Zentralantrieb seine Ausrichtung parallel zur Versatzrichtung verliert.It is advantageous if distributed in the offset direction at least two threaded spindles are arranged, the coupled via connecting means synchronously with each other are. Such connecting means can, for example Gears or chains, being ensured is that the rotation of a threaded spindle immediately on one or more other threaded spindles is transmitted. This makes it possible to support it the guide bar used in the width direction the warp knitting machine in several positions with Force to apply a displacement movement cause. This minimizes the risk that the Carrier with a control by the central drive loses its orientation parallel to the offset direction.

Die Erfindung wird im folgenden anhand eines bevorzugten Ausführungsbeispiels in Verbindung mit der Zeichnung näher beschrieben. Hierin zeigt:

The invention will be described below with reference to a preferred embodiment in conjunction with the drawings. Hereby shows:
the only figure
a schematic representation of a warp knitting machine.

Eine Kettenwirkmaschine 1 weist ein Maschinengestell 2 auf, in dem zwei Wirknadelbarren 3, 4 angeordnet sind. Ein Abstandsgewirke 5 ist zwischen den Wirknadelbarren 3, 4 zu erkennen.A warp knitting machine 1 has a machine frame 2 on, in which two knitting needles 3, 4 are arranged. A spacer fabric 5 is between the knitting needle bars 3, 4 to recognize.

Neben weiteren Wirkwerkzeugen 6, 7 weist die Wirkmaschine 1 Legenadeln in Form von Lochnadeln auf, die an sechs Legebarren 8-13 angeordnet sind. Hierbei sind jeweils zwei äußere Legebarren 8, 9 an Legebarrenhebeln 14 und die beiden anderen äußeren Legebarren 10, 11 an Legebarrenhebeln 15 angeordnet. Da die Legebarrenhebel 14, 15 in der Ansicht hintereinander angeordnet sind, ist jeweils nur ein Legebarrenhebel 14, 15 zu erkennen. Die Legebarren 8, 9 sind hauptsächlich der Wirknadelbarre 3 zugeordnet. Die Legebarren 8, 9 bzw. 10, 11 erzeugen hauptsächlich einen Warengrund. Die Legebarren 10, 11 sind hauptsächlich der Wirknadelbarre 4 zugeordnet. Die Legebarren 12, 13 dienen dazu, die Abstandsfäden des Abstandsgewirkes 5 zu legen. In addition to other knitting tools 6, 7, the knitting machine 1 guide needles in the form of perforated needles on six guide bars 8-13 are arranged. Here are each two outer guide bars 8, 9 on guide bar levers 14 and the other two outer guide bars 10, 11 at Guide bar levers 15 arranged. Because the guide bar levers 14, 15 are arranged one behind the other in the view, in each case only one guide bar lever 14, 15 can be seen. The guide bars 8, 9 are mainly the Wirknadelbarre 3 assigned. The guide bars 8, 9 and 10, 11 generate mainly a commodity reason. The guide bars 10, 11 are mainly associated with the knitting needle bar 4. The guide bars 12, 13 serve to the spacer threads of the spacer knitted fabric 5.

Die Legebarren 8-13 sind in an sich bekannter Weise in Versatzrichtung bewegbar, d.h. senkrecht zur Zeichenebene. Ein hierfür vorgesehener Antrieb ist nicht näher dargestellt.The guide bars 8-13 are in a conventional manner in Offset direction movable, i. perpendicular to the drawing plane. A dedicated drive is not closer shown.

Ferner können die Legebarren 8-13 so bewegt werden, daß die an ihnen befestigten Lochnadeln durch Nadelgassen an den Wirknadelbarren 3, 4 schwingen. Dies ist bezogen auf die Darstellung der Figur aus der in der Figur dargestellten Grundposition nach rechts bzw. nach links. Auch der hierfür notwendige Antrieb ist nicht extra dargestellt.Further, the guide bars 8-13 can be moved so that the needles attached to them through needle lanes swing at the knitting needle bar 3, 4. This is related to the representation of the figure from that shown in the figure Basic position to the right or to the left. Also, the necessary drive is not extra shown.

Die Hebel 14, die die beiden linken Legebarren 8, 9 tragen, sind an einer Traverse 16 befestigt. Die Traverse 16 ist auf einem Führungsschlitten 17 angeordnet, der auf Schienen 18 verlagerbar ist. Die Schienen 18 sind quer zur Versatzrichtung, d.h. quer zur Breitenrichtung der Kettenwirkmaschine 1 angeordnet. Zweckmäßigerweise wird man über die Breite der Kettenwirkmaschine mehrere Schlitten 17 mit entsprechenden Schienen 18 vorsehen, beispielsweise einen pro Legebarrenhebel, so daß die Traverse 16 in Breitenrichtung ausreichend unterstützt ist.The levers 14, the two left guide bars 8, 9 wear, are attached to a cross member 16. The traverse 16 is arranged on a guide carriage 17, which is displaceable on rails 18. The rails 18 are transverse to the offset direction, i. across the width direction the warp knitting machine 1 is arranged. Conveniently, you will be across the width of the warp knitting machine several carriages 17 with corresponding rails 18 provide, for example, one per Lege bar lever, so that the traverse 16 in the width direction sufficient is supported.

In ähnlicher Weise sind die Legebarrenhebel 15 an einer Traverse 19 befestigt, die auf einem Schlitten 20 angeordnet ist, der auf Schienen 21 verlagerbar ist. Die Schienen 21 weisen die gleiche Ausrichtung wie die Schienen 18 auf. Similarly, the guide bar levers 15 are at one Traverse 19 attached, which is arranged on a carriage 20 is, which is displaceable on rails 21. The Rails 21 have the same orientation as the Rails 18 on.

Eine Haupttraverse 22 ist etwa in der Mitte des Maschinengestells 2 angeordnet. Die Haupttraverse 22 ist ortsfest am Maschinengestell 2 befestigt.A main crossbar 22 is approximately in the middle of the machine frame 2 arranged. The main crossbar 22 is fixedly attached to the machine frame 2.

Eine Gewindespindel 23 weist einen ersten Gewindeabschnitt 24 auf, der mit einer Gewindebuchse 25 in Eingriff steht, die mit der ersten Traverse 16 verbunden ist. Ferner weist die Gewindespindel 23 einen zweiten Gewindeabschnitt 26 auf, der mit einer Gewindebuchse 27 in Eingriff steht, die mit der zweiten Traverse 19 verbunden ist.A threaded spindle 23 has a first threaded portion 24, which engages with a threaded bushing 25 is connected to the first Traverse 16 is. Furthermore, the threaded spindle 23 has a second Threaded portion 26 which, with a threaded bushing 27th is engaged, which is connected to the second cross member 19 is.

Die Gewindeabschnitte 24, 26 haben entgegengesetzt gerichtete Steigungen. Das gleiche gilt für die Gewindebuchsen 25, 27. Wenn nun die Gewindespindel 23 in eine Richtung gedreht wird, dann wird die erste Traverse 16 (bezogen auf die Darstellung der Figur) nach rechts bewegt und die zweite Traverse 19 nach links. Die beiden Traversen 16, 19 nähern sich also der Haupttraverse 22 an. Wenn die Gewindespindel 23 in die entgegengesetzte Richtung gedreht wird, dann werden die beiden Traversen 16, 19 von der Haupttraverse 22 entfernt.The threaded portions 24, 26 have oppositely directed Inclines. The same applies to the threaded bushings 25, 27. If now the threaded spindle 23 in a Direction is turned, then the first Traverse 16 (relative to the representation of the figure) moved to the right and the second crossbar 19 to the left. The two Traverses 16, 19 thus approach the main crossbar 22 at. When the threaded spindle 23 in the opposite Direction is turned, then the two traverses 16, 19 away from the main crossbar 22.

Wenn die beiden Gewindeabschnitte 24, 26 die gleiche Steigungshöhe haben, dann erfolgt die Bewegung der Traversen 16, 19 relativ zur Haupttraverse 22 symmetrisch, d.h. auch die Legebarren 8, 9 bzw. 10, 11 werden symmetrisch zu einer Mittelebene 29 verlagert. Man kann durch Verdrehen der Gewindespindel 23 auf einfache Weise dafür sorgen, daß die Legebarren 8, 9 bzw. 10, 11 den Wirknadelbarren 3, 4 nachgeführt werden, wenn die Wirknadelbarren 3, 4 verstellt werden. If the two threaded portions 24, 26 are the same Have pitch height, then the movement of the trusses 16, 19 symmetrically relative to the main beam 22, i.e. also the guide bars 8, 9 and 10, 11 are symmetrical shifted to a center plane 29. One can by turning the threaded spindle 23 in a simple manner ensure that the guide bars 8, 9 and 10, 11 the knitting needle bars 3, 4 are tracked when the Needle bars 3, 4 are adjusted.

Die Gewindespindel 23 ist an der Haupttraverse in Lagern 30, 31 gelagert. Ein Axialanschlag 32 sorgt dafür, daß sich die Gewindespindel 23 nicht in Richtung ihrer Längserstreckung verlagern kann.The threaded spindle 23 is on the main beam in bearings 30, 31 stored. An axial stop 32 ensures that the threaded spindle 23 is not in the direction of her Can shift longitudinal extent.

In vielen Fällen wird es ausreichen, eine einzige Gewindespindel 23 etwa in der Mitte der Traversen 16, 19, 22 anzuordnen. In manchen Fällen kann es allerdings sinnvoll sein, mehrere Gewindespindeln 23 über die Breite der Kettenwirkmaschine 1 zu verteilen. In diesem Fall ist es sinnvoll, die Gewindespindeln 23 mit Verbindungsmitteln zu verbinden, beispielsweise einem Zahnriemen 33 oder einer Kette, die über Kettenräder 34 geführt sind, die mit den jeweiligen Gewindespindeln 23 drehfest verbunden sind. In diesem Fall werden die Traversen 16, 19 über ihre Länge an mehreren Positionen verteilt mit einer Kraft zur Verlagerung beaufschlagt.In many cases it will be sufficient to have a single threaded spindle 23 about in the middle of the trusses 16, 19, 22 to arrange. In some cases, however, it can be useful, several threaded spindles 23 on the Width of the warp knitting machine 1 to distribute. In this Case, it makes sense, the threaded spindles 23 with connecting means to connect, for example one Timing belt 33 or a chain, the chain wheels 34th are guided, with the respective threaded spindles 23 are rotatably connected. In this case, the trusses 16, 19 over their length at several positions distributed with a force applied to the displacement.
