Description

Die Erfindung betrifft eine Fallblechanordnung einer Kettenwirkmaschine mit einem Fallblech, das sich parallel zu einer Versatzrichtung erstreckt, und einem Fallblechantrieb, der das Fallblech in einer Bewegungsrichtung senkrecht zur Versatzrichtung antreibt, wobei der Fallblechantrieb auf ein in Versatzrichtung bewegbares Antriebselement wirkt, das über eine Umlenkanordnung auf das Fallblech wirkt.The invention relates to a fall plate arrangement of a warp knitting machine with a fall plate which extends parallel to an offset direction, and a fall plate drive, which drives the fall plate in a direction perpendicular to the direction of displacement, wherein the fall plate drive acts on a movable in the offset direction drive element, via a deflection on the fall plate acts.

Eine derartige Fallblechanordnung ist aus US 3 568 470 A oder DE 1 635 874 B1 bekannt.Such a fall plate arrangement is made US 3,568,470 A or DE 1 635 874 B1 known.

In einer Kettenwirkmaschine arbeiten, vereinfacht ausgedrückt, Wirknadeln und Legenadeln zusammen, um Maschen einer Wirkware zu bilden. Die Wirknadeln sind dabei üblicherweise in einer Reihe an einer Wirknadelbarre angeordnet. Die Legenadeln können an mehreren Legenadelbarren angeordnet sein. Jede Legebarre trägt dann eine Reihe von Legenadeln. Zur Maschenbildung müssen die Legenadeln gegenüber den Wirknadeln parallel zu der Richtung der Reihe bewegt werden, in der die Legenadeln angeordnet sind. Diese Richtung wird auch als "Versatzrichtung" bezeichnet. In einem weiteren Bewegungsabschnitt werden die Legenadeln durch Gassen zwischen den Wirknadeln geführt. Danach schließt sich erneut eine Bewegung in Versatzrichtung an, allerdings entgegen der ersten Bewegung in Versatzrichtung. Die Legenadeln werden dann erneut durch Gassen zwischen Wirknadeln geführt, wobei dies in der Regel andere Gassen als beim ersten Mal sind.In a warp knitting machine, in simple terms, knitting needles and guide needles work together to form knits of a knitted fabric. The knitting needles are usually arranged in a row on a knitting needle bar. The guide needles can be arranged on a plurality of guide pin bars. Each guide bar then carries a set of guide needles. To form stitches, the guide needles must be moved in relation to the knitting needles parallel to the direction of the row in which the guide needles are arranged are. This direction is also referred to as "offset direction". In a further movement section, the guide needles are guided through alleys between the knitting needles. Thereafter, a movement in the offset direction joins again, but contrary to the first movement in the offset direction. The guide needles are then again passed through lanes between knitting needles, which are usually other lanes than the first time.

Bei bestimmten Musterungsvorgängen möchte man eine Maschenbildung vermeiden. Hierzu wird ein Fallblech verwendet, das Fäden niederhält oder verlagert, die zu diesem Zeitpunkt nicht für einen Maschenbildungsvorgang verwendet werden sollen. Dementsprechend muss das Fallblech senkrecht zur Versatzrichtung bewegt werden können. Aus Gründen der Einfachheit wird die Richtung, in der das Fallblech bewegt wird, als "Bewegungsrichtung" bezeichnet. Diese Bewegungsrichtung kann in vielen Fällen etwa parallel zu der Richtung verlaufen, in der die Wirknadeln bewegt werden.For certain patterning operations one would like to avoid looping. For this purpose, a fall plate is used, which holds down or shifts threads that should not be used for a stitch formation process at this time. Accordingly, the fall plate must be able to be moved perpendicular to the offset direction. For the sake of simplicity, the direction in which the fall plate is moved is referred to as the "direction of movement". This direction of movement can in many cases be approximately parallel to the direction in which the knitting needles are moved.

Eine weitere Fallblechanordnung einer Kettenwirkmaschine ist aus DE 1 585 440 A bekannt. Hier ist das Fallblech an einer Fallblechbarre befestigt, die an Stangen gehalten ist, die in einer Führung des Legebarren tragenden Gehänges geführt und von an der Hauptwelle der Kettenwirkmaschine angebrachten Exzentern über eine mehrgliedrige Hebelanordnung hin und her bewegt werden. Ein solcher Fallblechantrieb beinhaltet große bewegte Massen und eine relativ komplizierte Anordnung mit vielen Hebeln. Ein solcher Fallblechantrieb ist nur für Maschinengeschwindigkeiten der Kettenwirkmaschine bis etwa 500 U/min der Hauptwelle brauchbar.Another fall plate arrangement of a warp knitting machine is off DE 1 585 440 A known. Here, the fall plate is attached to a fall plate bar, which is held on rods, which are guided in a guide of the guide bar carrying hanger and moved by attached to the main shaft of the warp knitting eccentrics via a multi-membered lever arrangement back and forth. Such a fall plate drive includes large moving masses and a relatively complicated multi-lever arrangement. Such a fall plate drive is useful only for machine speeds of the warp knitting machine to about 500 rpm of the main shaft.

DE 66 06 595 U1 zeigt eine weitere Fallblechansteuerung, mit der die Bewegung des Fallblechs variiert und, falls gewünscht, mustermäßig ausgestaltet werden kann. Dies wird dadurch erreicht, dass ein Gelenkbolzen eines durch eine Exzenterwelle der Kettenwirkmaschine angetriebenen Stößels an einem mit dem Fallblech in Verbindung stehenden Winkelhebel angreift. In dem Winkelhebel ist der Stößel durch einen von einer Musterkette gesteuerten weiteren Stößel verschiebbar. DE 66 06 595 U1 shows a further fall plate control, with which the movement of the fall plate varies and, if desired, can be patterned. This is achieved in that a hinge pin of a driven by an eccentric shaft of the warp knitting machine ram on a engages with the fall plate associated angle lever. In the angle lever, the plunger is displaceable by a further plunger controlled by a pattern chain.

Auch dies ergibt eine relativ komplizierte Hebelanordnung, mit der die Drehbewegung der Hauptwelle unmittelbar in die schnelle Bewegung der Fallblechbarre in Bewegungsrichtung umgewandelt werden kann. Dementsprechend wird ein relativ großer Raum gebraucht für diese Teile, die darüber hinaus eine große Masse aufweisen.This also results in a relatively complicated lever arrangement, with which the rotational movement of the main shaft can be converted directly into the rapid movement of the fall plate bar in the direction of movement. Accordingly, a relatively large space is needed for these parts, which also have a large mass.

DE 197 36 123 C1 zeigt eine weitere Lösung für eine Fallblechbarre. Hier ist in einem Gehänge, das die Legebarren trägt, eine Zusatzwelle gelagert, die sich in Abhängigkeit von der Hauptwelle dreht und die Steuerkurven trägt. Die Zusatzwelle ist über ein Getriebe mechanisch mit der Hauptwelle verbunden. Die Fallblechbarre wird von den Steuerkurven über eine Hebelbarre in Bewegungsrichtung bewegt. Die Bewegungssteuerung erfolgt dabei über parallelogrammartig angeordnete Hebel, so dass eine lineare Bewegung der Fallblechbarre in Bewegungsrichtung erzielt werden kann. DE 197 36 123 C1 shows another solution for a fall plate bar. Here is in a hanger, which carries the guide bars, a supplementary shaft mounted, which rotates in response to the main shaft and carries the cams. The additional shaft is mechanically connected to the main shaft via a gearbox. The fall plate bar is moved by the control cams via a lever bar in the direction of movement. The movement control takes place via parallelogram arranged lever, so that a linear movement of the fall plate bar can be achieved in the direction of movement.

Der Erfindung liegt die Aufgabe zugrunde, eine Fallblechanordnung mit geringem Bauraum zu realisieren.The invention has for its object to realize a fall plate assembly with low space.

Diese Aufgabe wird bei einer Fallblechanordnung der eingangs genannten Art dadurch gelöst, dass das Fallblech eine Vorderseite und eine Rückseite aufweist und mit mindestens einer dieser beiden Seiten an einer Stützplatte anliegt.This object is achieved in a fall plate arrangement of the type mentioned above in that the fall plate has a front and a back and rests with at least one of these two sides of a support plate.

Damit kann man eine relativ komplizierte Hebelübersetzung vermeiden, bei der mehrere Hebel von der Hauptwelle der Kettenwirkmaschine angetrieben und verschwenkt werden müssen. Erforderlich ist lediglich ein Antriebselement, das in Versatzrichtung bewegbar ist. Eine Bewegung in Versatzrichtung wird bereits von den Legebarren durchgeführt, so dass man durchaus einen vergleichbaren Antrieb für die Fallblechanordnung verwenden kann. Die Umsetzung der Bewegung in Versatzrichtung in die Bewegung des Fallblechs in Bewegungsrichtung erfolgt über die Umlenkanordnung, die aber, weil sie lediglich eine einzige Bewegungsumlenkung durchführen muss, relativ klein und damit auch massearm ausgebildet sein kann. Man kann das Fallblech ohne größeren Aufwand antreiben und hohe Arbeitsgeschwindigkeiten ermöglichen. Auch ist eine variable Positionierung des Fallblechs möglich, ähnlich der Befestigung einer Legebarre. In der Regel kann man mit dieser Ausgestaltung mehrere Fallbleche verwenden und damit die Musterungsmöglichkeiten der Kettenwirkmaschine erweitern. Die Stützplatte ermöglicht es, dass das Fallblech relativ dünn und damit massearm ausgebildet sein kann. Eine Verformung des Fallblechs im Betrieb wird durch die Stützplatte erschwert oder sogar verhindert.This can avoid a relatively complicated leverage in which several levers must be driven and pivoted by the main shaft of the warp knitting machine. All that is required is a drive element which is movable in the offset direction. A movement in the offset direction is already carried out by the guide bars, so that one can certainly use a comparable drive for the fall plate assembly. The implementation of the movement in the offset direction in the movement of the fall plate in the direction of movement via the deflection, but because they only need to perform a single motion deflection, relatively small and thus can be designed low mass. You can drive the fall plate without much effort and allow high speeds. Also, a variable positioning of the fall plate is possible, similar to the attachment of a guide bar. In general, you can use this design several fall sheets and thus expand the patterning possibilities of the warp knitting machine. The support plate makes it possible that the fall plate can be made relatively thin and thus massearm. A deformation of the fall plate during operation is complicated by the support plate or even prevented.

Vorzugsweise ist der Fallblechantrieb in Versatzrichtung neben dem Fallblech angeordnet. Dies spart Bauraum. Darüber hinaus kann man auf bekannte Antriebskonzepte zurückgreifen, wie sie von den Antrieben für Legebarren bekannt sind. Wenn der Fallblechantrieb in Versatzrichtung neben dem Fallblech angeordnet ist, lassen sich auch die Übertragungswege kurz halten.The fall plate drive is preferably arranged in the offset direction next to the fall plate. This saves space. In addition, one can fall back on known drive concepts, as they are known from the drives for guide bars. If the fall plate drive is arranged in the offset direction next to the fall plate, the transmission paths can be kept short.

Hierbei ist besonders bevorzugt, dass das Fallblech zwischen zwei Stützplatten angeordnet ist oder eine Stützplatte zwischen zwei Fallblech-Trägerplatten angeordnet ist. Das Fallblech ist also sandwichartig zwischen zwei Stützplatten aufgenommen oder es gibt sich eine sandwichartige Konstruktion aus Stützplatte(n) und Fallblech-Trägerplatten. Dadurch wird eine Verformung des Fallblechs in sich auch bei schnelleren Bewegungen praktisch ausgeschlossen.In this case, it is particularly preferred that the fall plate is arranged between two support plates or a support plate is arranged between two fall plate carrier plates. The fall plate is thus sandwiched between two support plates or there is a sandwich-like construction of support plate (s) and fall plate carrier plates. As a result, deformation of the fall plate is practically impossible even with faster movements.

Bevorzugterweise weist die Umlenkanordnung eine Führungsbahn auf, in die das Fallblech mit einem Eingriffselement eingreift. Wenn die Führungsbahn in Versatzrichtung bewegt wird, dann wird das Eingriffselement entlang der Führungsbahn bewegt. Wenn man das Fallblech in Versatzrichtung festhält, dann lässt sich mit der Führungsbahn eine einfache Umsetzung der Bewegung in Versatzrichtung in eine Bewegung in Bewegungsrichtung erreichen.Preferably, the deflection arrangement has a guideway into which the fall plate engages with an engagement element. When the guideway is moved in the offset direction, the engagement member is moved along the guideway. If you have the fall plate in the offset direction holds, then can be achieved with the guideway, a simple implementation of the movement in the direction of displacement in a movement in the direction of movement.

Vorzugsweise weist das Eingriffselement eine Rolle auf, die in der Führungsbahn geführt ist. Durch die Rolle, die drehbar beispielsweise auf einem Zapfen gelagert sein kann, lässt sich die Reibung zwischen dem Eingriffselement und der Führungsbahn auf einem sehr geringen Niveau halten.Preferably, the engagement element has a roller which is guided in the guideway. Due to the roller, which can be rotatably mounted, for example, on a pin, the friction between the engaging member and the guide track can be kept at a very low level.

Hierbei ist bevorzugt, dass das Eingriffselement in Bewegungsrichtung in der oberen Hälfte des Fallblechs angeordnet ist. Damit lässt sich ermöglichen, dass das Fallblech trotz des Zusammenwirkens mit der Führungsbahn weit genug in Richtung auf die Wirknadeln verlagert werden kann, um die gewünschte Funktion zu erfüllen. Dennoch ist ein vergrößerter Bauraum nicht erforderlich.It is preferred that the engagement element is arranged in the direction of movement in the upper half of the fall plate. This makes it possible that the fall plate can be displaced far enough in the direction of the knitting needles despite the interaction with the guideway to fulfill the desired function. Nevertheless, an enlarged space is not required.

Vorzugsweise ist die Führungsbahn am Antriebselement angeordnet. In diesem Fall benötigt man keine zusätzlichen Elemente, um die Führungsbahn unterzubringen. Mit der Bewegung des Antriebselements wird gleichzeitig die Führungsbahn bewegt.Preferably, the guideway is arranged on the drive element. In this case, no additional elements are needed to accommodate the guideway. The movement of the drive element simultaneously moves the guideway.

Vorzugsweise ist die Führungsbahn geradlinig ausgebildet. In diesem Fall kann man die Bewegung des Antriebselements in Versatzrichtung proportional in eine Bewegung des Fallblechs in Bewegungsrichtung umsetzen. Dies vereinfacht die Steuerung. Alternativ kann die Führungsbahn auch kurvenförmig ausgebildet sein, wenn man eine bestimmte Bewegung des Fallblechs erzielen möchte.Preferably, the guideway is rectilinear. In this case, one can implement the movement of the drive element in the offset direction proportionally in a movement of the fall plate in the direction of movement. This simplifies the control. Alternatively, the guideway also be curved, if you want to achieve a certain movement of the fall plate.

Hierbei ist bevorzugt, dass die Führungsbahn mit der Versatzrichtung einen Winkel von maximal 45°, insbesondere maximal 30° und bevorzugterweise maximal 25° einschließt. Der Winkel definiert das Übersetzungsverhältnis. Je kleiner der Winkel ist, desto kleiner ist die Bewegung des Fallblechs pro Bewegungslänge des Antriebselements in Versatzrichtung. Andererseits wird bei einem kleinen Winkel auch die Reibung zwischen der Führungsbahn und dem Eingriffselement klein gehalten. Die Neigung der Führungsbahn gegenüber der Versatzrichtung ist also ein Kompromiss zwischen den Anforderungen an die Bewegung des Fallblechs in Bewegungsrichtung und den Reibungskräften, die man in Kauf nehmen möchte, sowie der benötigten Kraft und Dynamik des Fallblechantriebs.In this case, it is preferable for the guide track to include an angle of at most 45 °, in particular a maximum of 30 ° and preferably a maximum of 25 °, with the offset direction. The angle defines the gear ratio. The smaller the angle, the smaller the movement of the fall plate per movement length of the drive element in the offset direction. On the other hand, the friction between the guideway and the engagement member is kept small at a small angle. The inclination of the guideway with respect to the offset direction is thus a compromise between the requirements for the movement of the fall plate in the direction of movement and the frictional forces that one would like to accept, as well as the required force and dynamics of the fall plate drive.

Vorzugsweise bildet eine der Stützplatten das Antriebselement. In diesem Fall wirkt der Antrieb direkt oder über ein Verbindungsglied auf die Stützplatte. Wenn die Stützplatte verschoben wird, dann wird das Fallblech in Bewegungsrichtung verlagert.Preferably, one of the support plates forms the drive element. In this case, the drive acts directly or via a connecting link on the support plate. If the support plate is moved, then the fall plate is displaced in the direction of movement.

Hierbei ist bevorzugt, dass die Führungsbahn die Stützplatte durchsetzt. Die Führungsbahn wird also durch einen entsprechenden Schlitz in der Stützplatte gebildet. Dementsprechend ist das Eingriffselement auch von der dem Fallblech abgewandten Seite der Stützplatte aus sichtbar und man kann auf einfache Weise visuell kontrollieren, ob der Eingriff ordnungsgemäß gebildet ist.It is preferred that the guideway passes through the support plate. The guideway is thus formed by a corresponding slot in the support plate. Accordingly, the engagement element is also visible from the side facing away from the fall plate of the support plate and you can easily visually control whether the intervention is properly formed.

Vorzugsweise weist das Fallblech eine Führung in Bewegungsrichtung auf, die eine Bewegung des Fallblechs in Versatzrichtung beschränkt oder verhindert. Eine derartige Führung ermöglicht es auf einfache Weise, die Bewegung des Antriebselements in Versatzrichtung in eine Bewegung des Fallblechs in Bewegungsrichtung umzusetzen.Preferably, the fall plate on a guide in the direction of movement, which limits or prevents movement of the fall plate in the offset direction. Such a guide makes it possible in a simple manner to implement the movement of the drive element in the offset direction in a movement of the fall plate in the direction of movement.

Hierbei ist bevorzugt, dass die Führung einen Schlitz im Fallblech aufweist, in die ein stationär gehaltener Führungsbolzen eingreift. Der Schlitz ist dabei in Bewegungsrichtung des Fallblechs gerichtet.It is preferred that the guide has a slot in the fall plate into which a stationary held guide pin engages. The slot is directed in the direction of movement of the fall plate.

Vorzugsweise führt der Führungsbolzen das Antriebselement in Versatzrichtung. Hierzu kann das Antriebselement beispielsweise einen parallel zur Versatzrichtung ausgebildeten Schlitz aufweisen, in den der Führungsbolzen eingreift. Natürlich können auch am Führungsbolzen Rollen oder dergleichen angeordnet sein, um die Reibung zwischen dem Führungsbolzen und dem Antriebselement klein zu halten.Preferably, the guide pin guides the drive element in the offset direction. For this purpose, the drive element, for example, have a slot formed parallel to the offset direction, in which engages the guide pin. Of course, rollers or the like may also be arranged on the guide pin in order to keep the friction between the guide pin and the drive element small.

Die Erfindung wird im Folgenden anhand eines bevorzugten Ausführungsbeispiels in Verbindung mit der Zeichnung beschrieben. Hierin zeigt die

einzige Fig.:
eine stark schematisierte Darstellung einer Fallblechanordnung einer Kettenwirkmaschine.
The invention will be described below with reference to a preferred embodiment in conjunction with the drawings. Herein shows the
only Fig .:
a highly schematic representation of a fall plate assembly of a warp knitting machine.

Eine in der Figur nur schematisch dargestellte Fallblechanordnung 1 weist ein Fallblech 2 auf, das sich parallel zu einer durch einen Doppelpfeil symbolisierten Versatzrichtung 3 erstreckt.A fall plate arrangement 1 shown only schematically in the figure has a fall plate 2 which extends parallel to an offset direction 3 symbolized by a double arrow.

In einer Kettenwirkmaschine ist als Versatzrichtung 3 die Richtung definiert, in der die Wirkelemente an einer Barre in einer Reihe nebeneinander angeordnet sind. Die Versatzrichtung entspricht also zumindest im Wesentlichen der Breitenrichtung der Kettenwirkmaschine. Bei einem Maschenbildungsvorgang werden Legenadeln gegenüber Wirknadeln in Versatzrichtung bewegt, danach durch Gassen zwischen Wirknadeln, danach erneut in Versatzrichtung entgegen der ersten Bewegung in Versatzrichtung und schließlich wieder durch Gassen zwischen den Wirknadeln.In a warp knitting machine, the direction in which the knitting elements are arranged next to one another on a bar in a row is defined as the offset direction 3. The offset direction thus corresponds at least substantially to the width direction of the warp knitting machine. In a stitch forming process guide needles are compared with knitting needles moved in the offset direction, then through streets between knitting needles, then again in the direction of offset against the first movement in the direction of offset and finally again by streets between the knitting needles.

Wenn in der vorliegenden Beschreibung von Begriffen, wie "parallel" oder "senkrecht" die Rede ist, dann sind diese Begriffe nicht im mathematisch strengen Sinn zu verstehen. Vielmehr reicht es aus, wenn die durch diese Begriffe definierten Richtungen im Wesentlichen eingehalten werden.When in the present description of terms such as "parallel" or "vertical" is mentioned, then these terms are not to be understood in a mathematically rigorous sense. Rather, it is sufficient if the directions defined by these terms are essentially adhered to.

Im Betrieb muss das Fallblech 2 gelegentlich bewegt werden und zwar in eine durch einen Doppelpfeil symbolisierte Bewegungsrichtung 4. Die Bewegungsrichtung 4 ist senkrecht zur Versatzrichtung 3 gerichtet.In operation, the fall plate 2 must be moved occasionally, in a symbolized by a double arrow movement direction 4. The direction of movement 4 is directed perpendicular to the offset direction 3.

Das Fallblech 2 ist zwischen einer ersten Stützplatte 5 und einer zweiten Stützplatte 6 sandwichartig aufgenommen. Das Fallblech 2 ist also sowohl an seiner der ersten Stützplatte 5 zugewandten Vorderseite als auch an seiner der zweiten Stützplatte 6 zugewandten Rückseite abgestützt und kann dementsprechend praktisch nicht verformt werden. Dementsprechend kann das Fallblech 2 auch relativ dünn ausgebildet sein.The fall plate 2 is sandwiched between a first support plate 5 and a second support plate 6. The fall plate 2 is thus both at its the first Supporting plate 5 facing the front and supported on the second support plate 6 facing back and can therefore be practically not deformed. Accordingly, the fall plate 2 may be formed relatively thin.

In vielen Fällen wird aber auch eine einzige Stützplatte, beispielsweise die erste Stützplatte 5, ausreichen, um das Fallblech 2 abzustützen.In many cases, however, a single support plate, for example, the first support plate 5, sufficient to support the fall plate 2.

Die erste Stützplatte 5 ist als Antriebselement ausgebildet, auf die ein durch einen Pfeil symbolisierter Antrieb 7 in Versatzrichtung 3 wirkt. Der Antrieb 7 kann beispielsweise ähnlich ausgebildet sein, wie ein Musterantrieb einer Legebarre, d.h. er kann eine direkt oder indirekt von einer Hauptwelle der Kettenwirkmaschine angetriebene Musterscheibe oder eine Musterkette aufweisen oder er kann als Linearantrieb ausgebildet sein, der in Versatzrichtung 3 wirkt.The first support plate 5 is designed as a drive element, acts on a symbolized by an arrow drive 7 in the offset direction 3. For example, the drive 7 may be similar in design to a pattern drive of a guide bar, i. it can have a pattern disk or a pattern chain driven directly or indirectly by a main shaft of the warp knitting machine or it can be designed as a linear drive which acts in the offset direction 3.

Die erste Stützplatte 5 weist eine als geradlinig verlaufender Schlitz ausgebildete Führungsbahn 8 auf, in die ein als Stift 9 ausgebildetes Einsatzelement eingreift. Auf dem Stift 9 ist eine Rolle 10 drehbar gelagert, so dass sich eine Bewegung des Stifts 9 in der Führungsbahn 8 mit relativ geringer Reibung realisieren lässt.The first support plate 5 has a guideway 8 designed as a straight slot, into which engages an insert element designed as a pin 9. On the pin 9, a roller 10 is rotatably mounted, so that a movement of the pin 9 can be realized in the guideway 8 with relatively little friction.

Die Führungsbahn 8 ist gegenüber der Versatzrichtung 3 geneigt. Der Winkel zwischen der Versatzrichtung 3 und der Führungsbahn 8 sollte maximal 45° betragen, vorzuziehen sind jedoch kleinere Winkel, beispielsweise maximal 30° oder maximal 25°.The guideway 8 is inclined relative to the offset direction 3. The angle between the offset direction 3 and the guideway 8 should be a maximum of 45 °, preferable However, smaller angles, for example, a maximum of 30 ° or a maximum of 25 °.

Selbstverständlich können über die Länge der ersten Stützplatte 5 in Versatzrichtung 3 verteilt mehrere derartige Führungsbahnen 8 vorgesehen sein, wobei dann das Fallblech 2 auch mehrere Stifte 9 mit Rollen 10 aufweist.Of course, distributed over the length of the first support plate 5 in the offset direction 3 more such guideways 8 may be provided, in which case the fall plate 2 also has a plurality of pins 9 with rollers 10.

Das Fallblech 2 weist einen in Bewegungsrichtung verlaufenden Schlitz 11 auf. Durch den Schlitz 11 ragt ein Führungsbolzen 12, der an einem Maschinengestell 13, das hier durch eine Platte symbolisiert ist, befestigt ist. Der Führungsbolzen 12 ist also stationär, so dass er eine Bewegung des Fallblechs 2 in Versatzrichtung 3 verhindert. In nicht näher dargestellter Weise ist der Führungsbolzen 12 im Bereich des Schlitzes 11, der eine Führung des Fallblechs 2 in Bewegungsrichtung 4 bildet, mit einer Rolle versehen, die ähnlich ausgebildet ist, wie die Rolle 10 auf dem Stift 9 des Fallblechs.The fall plate 2 has a slot 11 extending in the direction of movement. Through the slot 11 projects a guide pin 12 which is fixed to a machine frame 13, which is symbolized here by a plate. The guide pin 12 is thus stationary, so that it prevents movement of the fall plate 2 in the offset direction 3. In a manner not shown, the guide pin 12 is provided in the region of the slot 11, which forms a guide of the fall plate 2 in the direction of movement 4, with a roller which is designed similar to the roller 10 on the pin 9 of the fall plate.

In der ersten Stützplatte 5 ist ferner ein Schlitz 14 vorgesehen, der parallel zur Versatzrichtung 3 verläuft. Der Führungsbolzen 12 durchragt auch diesen Schlitz 14, wobei am Führungsbolzen 12 eine weitere Rolle 15 angeordnet ist, die eine Reibung zwischen dem Schlitz 14 und dem Führungsbolzen 12 klein hält. Natürlich können über die Länge der ersten Stützplatte 5 verteilt wiederum mehrere Schlitze 14 mit Führungsbolzen 12 vorgesehen sein.In the first support plate 5, a slot 14 is further provided, which extends parallel to the offset direction 3. The guide pin 12 extends through this slot 14, wherein the guide pin 12, a further roller 15 is arranged, which holds a friction between the slot 14 and the guide pin 12 small. Of course, distributed over the length of the first support plate 5 in turn several slots 14 may be provided with guide pins 12.

Wenn nun der Antrieb 7 auf die erste Stützplatte 5 wirkt, dann kann dies nur zu einer Bewegung der ersten Stützplatte 5 in Versatzrichtung führen, weil diese Bewegung durch das Zusammenwirken des Führungsbolzens 12 mit dem Schlitz 14 erzwungen wird.Now, if the drive 7 acts on the first support plate 5, then this can only be a movement of the first support plate 5 lead in the offset direction, because this movement is enforced by the interaction of the guide pin 12 with the slot 14.

Dieser Bewegung in Versatzrichtung 3 kann allerdings das Fallblech 2 nicht folgen, weil dies durch das Zusammenwirken des Führungsbolzens 12 mit dem in Bewegungsrichtung 4 verlaufenden Schlitz 11 verhindert wird. Dementsprechend wird die Bewegung der ersten Stützplatte 5 durch das Zusammenwirken der Führungsbahn 8 mit dem Stift 9 und der Rolle 10 in eine Bewegung des Fallblechs 2 in Bewegungsrichtung 4 umgesetzt. Je nach Neigung der Führungsbahn 8 gegenüber der Versatzrichtung 3 erfolgt dann eine gewisse Übersetzung. Bei einem Winkel von 45°, den die Führungsbahn 8 mit der Versatzrichtung 3 einschließt, ergibt sich eine Bewegungsübersetzung von 1:1. Bei einem Winkel von 30° ergibt sich eine Bewegungsübersetzung von 1:2, d.h. wenn sich die erste Stützplatte 5 um zwei Millimeter in Versatzrichtung 3 bewegt, dann bewegt sich das Fallblech 2 in Bewegungsrichtung 4 um einen Millimeter.However, the fall plate 2 can not follow this movement in the offset direction 3, because this is prevented by the interaction of the guide pin 12 with the running in the direction of movement 4 slot 11. Accordingly, the movement of the first support plate 5 is converted by the interaction of the guideway 8 with the pin 9 and the roller 10 in a movement of the fall plate 2 in the direction of movement 4. Depending on the inclination of the guideway 8 relative to the offset direction 3 then takes a certain translation. At an angle of 45 °, which includes the guideway 8 with the offset direction 3, results in a motion ratio of 1: 1. At an angle of 30 ° there is a motion translation of 1: 2, i. when the first support plate 5 moves by two millimeters in the offset direction 3, then the fall plate 2 moves in the direction of movement 4 by one millimeter.

Anstelle einer geradlinigen Führungsbahn 8 kann man auch eine gekrümmte Führungsbahn verwenden. In diesem Fall ist die Umsetzung der Bewegung zwischen der Stützplatte 5 und dem Fallblech 2 nicht mehr direkt proportional, sondern kann nach gewünschten Vorgaben gesteuert werden.Instead of a linear guideway 8 can also use a curved guideway. In this case, the implementation of the movement between the support plate 5 and the fall plate 2 is no longer directly proportional, but can be controlled according to desired specifications.

Der Fallblechantrieb 7 kann aufgrund der beschriebenen Wirkung unmittelbar neben dem Fallblech 2 in Versatzrichtung 3 angeordnet sein. Natürlich sind Übertragungselemente, wie sie von Legebarren her bekannt sind, verwendbar, beispielsweise Stößel oder dergleichen.Due to the described effect, the fall plate drive 7 can be arranged directly next to the fall plate 2 in the offset direction 3. Of course, transmission elements, as they are known from Legebarren ago usable, for example plunger or the like.

Der Stift 9 mit der Rolle 10, die das Eingriffselement bilden, sind in Bewegungsrichtung 4 in der oberen Hälfte des Fallblechs 2 angeordnet, so dass das Fallblech 2 weit genug in Bewegungsrichtung über die erste Stützplatte 5 hinausgeführt werden kann, um seine Funktion sicher zu erfüllen. Der Schlitz 8 kann sich dabei über fast die gesamte Erstreckung der ersten Stützplatte 5 in Bewegungsrichtung 4 erstrecken, so dass man mit dem Fallblech 2 einen relativ großen Hub durchführen kann.The pin 9 with the roller 10, which form the engagement element are arranged in the direction of movement 4 in the upper half of the fall plate 2, so that the fall plate 2 can be far enough out in the direction of movement over the first support plate 5 to perform its function safely , The slot 8 can extend over almost the entire extent of the first support plate 5 in the direction of movement 4, so that you can perform a relatively large stroke with the fall plate 2.

Natürlich kann man nicht nur die erste Stützplatte 5, sondern dann auch die zweite Stützplatte 6 als Antriebselement verwenden. In diesem Fall haben die beiden Stützplatten 5, 6 entsprechend als Führungsbahnen ausgebildete Schlitze 8, 14 und das Fallblech 2 hat dann sowohl an seiner Vorderseite als auch an seiner Rückseite ein Eingriffselement 9, 10.Of course, you can use not only the first support plate 5, but then the second support plate 6 as a drive element. In this case, the two support plates 5, 6 corresponding to slots formed as guideways 8, 14 and the fall plate 2 then has both on its front side and on its rear side an engagement element 9, 10th

Der Antrieb der Antriebselemente, d.h. der Stützplatten 5, 6 kann gleichläufig oder gegenläufig erfolgen. Bei gleichläufigem Antrieb sind die Führungsbahnen 8 in den Stützplatten 5, 6 im gleichen Winkel angeordnet. Bei gegenläufigem Antrieb sind die Führungsbahnen im entgegengesetzten Winkel angeordnet. Der gegenläufige Antrieb kann beispielsweise über einen Wickelantrieb realisiert werden.The drive of the drive elements, ie the support plates 5, 6 can take place in the same direction or in opposite directions. When co-driving the guideways 8 are arranged in the support plates 5, 6 at the same angle. With opposite drive the guideways are arranged at opposite angles. The opposite drive can be realized for example via a winding drive.

Die sandwichartige Anordnung kann auch so aufgebaut sein, dass man eine Stützplatte zwischen zwei Fallblech-Trägerplatten anordnet oder allgemein eine Folge von Stützplatten und Fallblech-Trägerplatten, die abwechselnd angeordnet sind.The sandwich may also be constructed by arranging a support plate between two fall plate support plates or generally a series of support plates and fall plate support plates arranged alternately.

Durch eine Einstellmöglichkeit der Antriebselemente, hier die Stützplatten 5, 6, in Versatzrichtung 3 relativ zueinander können die Antriebselemente spielfrei eingestellt werden.By adjusting the drive elements, here the support plates 5, 6, in the offset direction 3 relative to each other, the drive elements can be adjusted without play.

Die Fallblechanordnung ermöglicht eine relativ flexible Positionierung des Fallblechs in einer Kettenwirkmaschine, da die Fallblechanordnung 1 wie eine Legebarre an jeder Barren tragenden Position in der Kettenwirkmaschine angebracht werden kann. So können auch mehrere Fallblechanordnungen zur Musterung in einer Kettenwirkmaschine eingebaut werden.The fall plate assembly allows for relatively flexible positioning of the fall plate in a warp knitting machine because the fall plate assembly 1, such as a guide bar, can be attached to any bar bearing position in the warp knitting machine. Thus, several fall plate arrangements can be installed for patterning in a warp knitting machine.
