Description

Jacquardmaschinen werden zum Weben von Figuren in Polgeweben angewendet. Beim Weben von Doppel-polgeweben gibt es zwei Grundgewebe: das Obergewebe und das Untergewebe, die mit ihren Oberseiten einander zugekehrt sind, und die während des Webens durch die Florkettfäden verbunden werden. Die Florkettfäden können beim Weben drei Positionen einnehmen, nämlich oberhalb des Obergewebes, in der Mitte zwischen den beiden Grundgeweben oder unter dem Untergewebe. Dies ist diejenige Jacquardmaschine, die jeden Florkettfaden vor jedem Schuss in eine jener Positionen hineinbringt.Jacquard machines are used to weave figures in pile fabrics. When weaving double-pile fabrics, there are two basic fabrics: the upper fabric and the lower fabric, which face each other with their tops and which are connected by the pile warp threads during weaving. The pile warp threads can assume three positions during weaving, namely above the upper fabric, in the middle between the two basic fabrics or below the lower fabric. This is the jacquard machine that brings each pile warp thread into one of those positions before each shot.

In der belgischen Patentschrift Nr. 894.283 ist eine Rollenzugeinrichtung einer Offenfach-Jacquardmaschine beschrieben, bei der das eine Ende der Strupfe an einer Platine und das andere Ende an einer bewegbaren Aufhänge-Einrichtung bzw. zugleich die Harnischschnüre mit einem Aussenende am Harnisch und mit dem anderen Ende an einer festen Aufhänge-Einrichtung festgemacht sind.Belgian patent specification No. 894.283 describes a roller pulling device of an open-pocket jacquard machine, in which one end of the stockings on a circuit board and the other end on a movable suspension device, or at the same time the harness cords with an outer end on the harness and with the other Are attached to a fixed suspension device.

Die bewegbare Aufhänge-Einrichtung besteht dabei aus auf- und abbewegbaren Brettern an denen die Enden einer oder mehrerer Strupfe festgemacht werden, so dass jene Enden blockweise, einem bestimmten Rapport folgend, gesteuert werden können.The movable suspension device consists of up and down movable boards on which the ends of one or more strings are fastened, so that those ends can be controlled in blocks, following a specific repeat.

Eine derartige Rollenzugeinrichtung übernimmt die Vorteile der Offenfach-Jacquardmaschine mit Rollenzug-Elementen, umgeht den Nachteil, dass je angesteuertem Punkt zwei Platinen zu gebrauchen sind, und lässt maximale Musterungsmöglichkeiten bei geringstem Platzbedarf zu.Such a roller pulling device takes over the advantages of the open-pocket jacquard machine with roller pulling elements, avoids the disadvantage that two boards have to be used for each point controlled, and permits maximum patterning options with the smallest space requirement.

Während beim Gegenstand des belgischen Patentes die Bretter von einer Kurve über einen Hebegetriebe angetrieben werden, also ein gesonderter Antrieb notwendig ist, ist es das Ziel der vorliegenden Erfindung, den zusätzlichen Antrieb zu vermeiden.While the boards of the Belgian patent are driven by a curve via a lifting gear, a separate drive is required , the aim of the present invention is to avoid the additional drive.

Die Jacquardmaschine gemäss der Erfindung, bei der das eine Aussenende der Strupfen an einer Platine und das andere Aussenende an einer bewegbaren AufhängeEinrichtung und die Harnischschnüre mit einem Aussenende am Harnisch und dem anderen Aussenende an einer festen Aufhänge-Einrichtung festgemacht sind, ist dadurch gekennzeichnet, dass die bewegbaren Aufhänge-Einrichtungen von dem Messerrost der Jacquardmaschine angetrieben werden und daß die bewegbaren Aufhänge-Einrichtungen jeweils an einer Anzahl Platinen aufgehängt sind, die an dem Messerrost der Jacquardmaschine einhaken können, und die dazu mit eingenen Steuernadeln versehen sind.The jacquard machine according to the invention, in which the one outer end of the hosiery is attached to a board and the other outer end to a movable suspension device and the harness cords with an outer end to the harness and the other outer end to a fixed suspension device, is characterized in that the movable suspension devices are driven by the knife grate of the jacquard machine and that the movable suspension devices are each suspended on a number of boards which can hook onto the knife grate of the jacquard machine and which are provided with their own control needles for this purpose.

Bei einer bevorzugten Ausführungsform der Jacquardmaschine gemäss der Erfindung besteht jede Platine, die einen Teil der bewegbaren Aufhänge-Einrichtung trägt, aus zwei nahe beieinander angeordneten Flachstahl- oder Kunststoffleisten, die in passender Höhe mit einer hakenförmigen Nase versehen sind, die auf den Messerreihen einhaken kann.In a preferred embodiment of the jacquard machine according to the invention, each plate, which carries part of the movable suspension device, consists of two flat steel or plastic strips arranged close to one another, which are provided at a suitable height with a hook-shaped nose which can hook onto the rows of knives .

Bezüglich der in der belgischen Patentschrift Nr. 894.283 beschriebenen Jacquardmaschine hat die Jacquardmaschine gemäss der Erfindung den Vorteil, dass der zusätzliche Antrieb für jedes bewegbare Brett vermieden wird, dass die Synchronisierung zwischen der Bewegung der Platinen und der des Brettes leichter zu realisieren ist, und dass die Bewegung des Brettes leichter und umfassender zu programmieren ist.With respect to the jacquard machine described in Belgian Patent No. 894,283, the jacquard machine according to the invention has the advantage that the additional drive for each movable board is avoided, that the synchronization between the movement of the boards and that of the board is easier to implement, and that the movement of the board is easier and more comprehensive to program.

Um die Arbeitsweise der Jacquardmaschine gemäss der Erfindung gut zu verstehen, wird das Prinzip einer Jacquardmaschine mit blockweise gesteuerten Rollenzugeinrichtungen anhand der Figur 1 kurz erläutert. Bei einer solchen Jacquardmaschine trägt eine Platine 1 das eine Ende 2 einer Rollenstrupfe 3, die um eine Rolle 4 läuft. Das andere Ende 5 jener Rollenstrupfe 3 ist beispielsweise an einer bewegbaren Aufhänge-Einrichtung, vorzugsweise einem Brett 6 oder 7 befestigt. Jedes Brett 6 oder 7 trägt das Ende mehrerer Rollenstrupfe 3. Der Rolle 4 ist eine Rolle 8 zugeordnet, um die eine Harnischschnur 9 herumläuft, deren eines Ende 10 dann mit einer festen Aufhänge-Einrichtung 11 und deren anderes Ende 12 mit dem Harnisch (nicht gezeigt) verbunden ist. Um die Kettfäden I, II, III, IV wahlweise in eine ihrer drei möglichen Positionen zu bewegen, genügt es, die Platinen 1 in eine von zwei mit "unten" (0) oder "oben" (B) bezeichnete Positionen zu bewegen in Kombination mit den Brettern 6 oder 7, die in ein von zwei mit "unten" (0) oder "oben" (B) bezeichnete Positionen zu bewegen sind.In order to understand the operation of the jacquard machine according to the invention well, the principle of a jacquard machine with block-controlled roller pulling devices will be briefly explained with reference to FIG. 1. In such a jacquard machine, a board 1 carries one end 2 of a roller hosiery 3, which runs around a roller 4. The other end 5 of those roller straps 3 is fastened, for example, to a movable suspension device, preferably a board 6 or 7. Each board 6 or 7 carries the end of several roller treads 3. The roller 4 is assigned a roller 8, around which a harness cord 9 runs, one end 10 of which is then fixed with a suspension device 11 and the other end 12 of which is the harness (not shown) is connected. In order to selectively move the warp threads I, II, III, IV into one of their three possible positions, it is sufficient for the sinkers 1 to move into one of two positions labeled "down" (0) or "up" (B) in combination with boards 6 or 7 that move into one of two with "down" (0) or "up" (B) designated positions are to be moved.

Aus der Figur 1 ergibt sich somit, dass die Bretter 6 oder 7 in der Lage sein müssen, vier mögliche Bewegungsübergänge auszuführen: oben _ oben, oben _ unten, unten _ unten, unten _ oben. In der Figur 1 ist ferner der Platinenboden 13 der Jacquardmaschine angedeutet.It therefore follows from FIG. 1 that the boards 6 or 7 must be able to carry out four possible movement transitions: top _ top, top _ bottom, bottom _ bottom, bottom _ top. In FIG. 1, the base 13 of the jacquard machine is also indicated.

Bei der Jacquardmaschine gemäss der Erfindung, die in den Figuren 2 und 4 gezeigt ist, werden jene Bewegungsübergänge der bewegbaren Aufhänge-Einrichtungen, in diesem Fall der Bretter 6 oder 7 durch die Jacquardmaschine selbst angetrieben.In the jacquard machine according to the invention, which is shown in FIGS. 2 and 4, those movement transitions of the movable suspension devices, in this case the boards 6 or 7, are driven by the jacquard machine itself.

Bei einer ersten Ausführungsform der Jacquardmaschine gemäss der Erfindung, die in der Figur 2 dargestellt ist, wird ein Brett 6 mit Hilfe einer Anzahl Platinen 14 der klassischen Jacquardmaschine aufgehängt. Jene Platinen 14 sind auf eine gewisse Zahl Reihen, in der Tiefenrichtung des Brettes 6 und parallel zu den Seitenrändern des Brettes 6 gelegen, und können von den Messern 15 der Messerroste mitgenommen werden. Dazu werden alle Platinen 14 einer Reihe von einem Brett jeweils durch eine horizontale Verschiebung von sich gemeinsam bewegenden Steuernadeln 16 innerhalb oder ausserhalb des Bereiches der Messer 15 angeordnet. Genauso wie die Platinen 1 der Rollenstrupfe 3 der Figur 1 können auch die Platinen 14 infolge ihres Zusammenwirkens mit den Messern 15 der Messerroste die vier Übergänge zwischen den beiden erforderlichen Positionen oben und unten durchlaufen.In a first embodiment of the jacquard machine according to the invention, which is shown in FIG. 2, a board 6 is suspended using a number of sinkers 14 of the classic jacquard machine. Those boards 14 are located on a certain number of rows, in the depth direction of the board 6 and parallel to the side edges of the board 6, and can be taken along by the knives 15 of the knife grids. For this purpose, all the boards 14 in a row are arranged by a board, in each case by means of a horizontal displacement of control needles 16 moving together, inside or outside the area of the knives 15. Just like the sinkers 1 of the roller brackets 3 in FIG. 1, the sinkers 14 can also pass through the four transitions between the two required positions above and below due to their interaction with the knives 15 of the knife grids.

In bestimmten Fällen haben die Platinen der klassischen Jacquardmaschine eine zu geringe Stärke. Im Hinblick darauf, dass der Angriffspunkt 17 eines Teiles des Gewichtes und der Belastung des Brettes 6 nicht genau unterhalb der Nasen 18 der Platinen 14 liegt, kann sich eine derartige Platine bei einer hohen Belastung unter dem Einfluss des in ihr auftretenden Biegemomentes verbiegen, so dass die Nasen 18 nicht mehr in der Bahn der Messer 15 bleiben und eine einwandfreie Arbeitsweise der Jacquardmaschine nicht mehr gewährleistet ist.In certain cases, the boards of the classic jacquard machine are too thin. In view of the fact that the point of attack 17 of part of the weight and the load on the board 6 is not exactly below the lugs 18 of the boards 14, can Such a plate bends under a high load under the influence of the bending moment occurring in it, so that the lugs 18 no longer remain in the path of the knives 15 and the jacquard machine can no longer function properly.

Um diesem Problem abzuhelfen, wurde eine neue Platine entwickelt, die aus zwei Flachstahl- oder Kunststoffleisten 19 und 20 (Figur 3) besteht. Jede klassische Platine 14 der Figur 2 wird somit durch die beiden Leisten 19 und 20 ersetzt, die in passender Höhe mit hakenförmigen Nasen 21 versehen sind, die mit den Nasen 18 der klassischen Platinen 14 (Figur 2) übereinstimmen. Jene Leisten 19 und 20 sind dann derart in der Jacquardmaschine angeordnet, dass die Steuernadel 16 ihren kleinsten Leisten-Biegewiderstand zu überwinden hat, oder dass die kleinste Abmessung des Leisten-Querschnittes parallel zur Bewegung der Nadel 16 verläuft. Der Querschnitt der Leisten 19 und 20 ist somit derart gewählt, dass er zur Aufnahme der Brettbelastungen gross genug ist, und dass er in einer einzigen Richtung den gewünschten, geringen Biegewiderstand aufweist.To remedy this problem, a new circuit board was developed, which consists of two flat steel or plastic strips 19 and 20 (Figure 3). Each classic circuit board 14 of FIG. 2 is thus replaced by the two strips 19 and 20, which are provided at the appropriate height with hook-shaped lugs 21 which correspond to the lugs 18 of the classic circuit boards 14 (FIG. 2). Those strips 19 and 20 are then arranged in the jacquard machine in such a way that the control needle 16 has to overcome its smallest strip bending resistance, or that the smallest dimension of the strip cross section runs parallel to the movement of the needle 16. The cross section of the strips 19 and 20 is thus selected such that it is large enough to take up the board loads and that it has the desired low bending resistance in a single direction.

Jene Leiste 19 und 20 werden dann unten jeweils paarweise mit Scharnieren am Seitenrand entlang und in der Tieferichtung des Brettes 6 befestigt (Figur 4); Jene Scharnierverbindung kann aus einer kurzen Achse 22 bestehen, die am Brett 6 befestigt ist, und um die sich das ringförmige Aussenende der Leisten 19 und 20 dreht. Diese Leisten 19 und 20 laufen frei nach oben durch den Platinenboden 13 hindurch. Oberhalb sind sie in eine feste Geradführung 23 eingeschoben, die eine gewisse Verbiegung der Leisten 19 und 20 zulässt. Das obere Ende der Leisten 19 und 20 wird dazu beispielsweise drehbar oder mit einigem Spiel in einem kleinen Führungsblock eingefasst.Those strips 19 and 20 are then attached in pairs at the bottom with hinges along the side edge and in the lower direction of the board 6 (FIG. 4); That hinge connection can consist of a short axis 22 which is fastened to the board 6 and about which the ring-shaped outer end of the strips 19 and 20 rotates. These strips 19 and 20 run freely upwards through the board base 13. Above, they are inserted into a fixed straight guide 23, which permits a certain bending of the strips 19 and 20. For this purpose, the upper end of the strips 19 and 20 is, for example, rotatably or with some play enclosed in a small guide block.

Die Scharnierverbindung unten kann auch mit Spiel ausgeführt sein. Eine bevorzugte Ausführungsform jener Verbindung ist in Figur 3 gezeigt. An den Stellen, an denen die Leisten 19 oder 20 in das Brett 6 eingreifen, ist stets ein Nut 24 vorgesehen. In der Tieferichtung des Brettes 6 und durch die Nut 24 hindurch ein oder zwei Öffnungen 25 ausgebildet, durch die ein langer Stab 26 hindurchgeschoben wird. Die unteren Aussenenden der Leisten 19 und 20 sind ebenfalls mit einer oder zwei Öffnungen 27 versehen, deren Querschnitt jedoch grösser als der des Stabes 26 ist. Die Leisten 19 und 20 können auf diese Weise leicht mit dem Brett 6 verbunden oder vom Brett 6 getrennt werden. Es genügt, den Stab 26 hinein oder hinaus und dabei durch die Öffnungen 27 zu schieben. Infolge des Unterschiedes in den Abmessungen ist ein gewisses Spiel an dieser Verbindung vorhanden. Dieses ist notwendig, weil der Brett 6 während seiner Aufwärtsbewegung noch einer leichten Schrägstellungsbewegung, der sog. Schrägfachbewegung, unterliegt.The hinge connection below can also be designed with play. A preferred embodiment that connection is shown in FIG. A groove 24 is always provided at the points at which the strips 19 or 20 engage in the board 6. In the lower direction of the board 6 and through the groove 24, one or two openings 25 are formed through which a long rod 26 is pushed. The lower outer ends of the strips 19 and 20 are also provided with one or two openings 27, the cross section of which, however, is larger than that of the rod 26. The strips 19 and 20 can be easily connected to the board 6 or separated from the board 6 in this way. It is sufficient to push the rod 26 in or out and thereby through the openings 27. Due to the difference in dimensions, there is some play on this connection. This is necessary because the board 6 is still subject to a slight inclination movement, the so-called inclined compartment movement, during its upward movement.

Auch die Steuernadel 16 (Figur 3) hat bei dieser zweiten Ausführungsform eine entsprechend angepasste Gestalt. In der Höhe der Leiste 19 oder 20 ist die Steuernadel 16 mit zwei Röllchen 28 versehen, die zwischen den hakenförmigen Nasen 21 an den Leisten 19 oder 20 angreifen. Alle Steuernadeln 16 desselben Bretts 6 unterliegen derselben Bewegung, die durch einen Kurvensteuerung, durch einen oder mehrere Druckzylinder oder durch einem aus den Jacquard-Karten gesteurerten Vorwahlapparat erzeugt wird.The control needle 16 (FIG. 3) also has a correspondingly adapted shape in this second embodiment. At the level of the strip 19 or 20, the control needle 16 is provided with two rollers 28 which engage between the hook-shaped lugs 21 on the strips 19 or 20. All control needles 16 of the same board 6 are subject to the same movement which is generated by a cam control, by one or more printing cylinders or by a preselection device controlled by the jacquard cards.

Diese Bewegung ist einfach mit der Bewegung der gewöhnlichen Platinen zu synchronisieren, die die Rollenstrupfe hochheben; sie ist leicht mit den Jacquardkarten zu programmieren.This movement is easy to synchronize with the movement of the ordinary boards that lift the roller brackets; it is easy to program with the jacquard cards.

Bei der ersten Ausführungsform gemäss Figur 2 hängt das Brett 6 in seiner untersten Position an den Platinen 14, die sich auf der Oberseite des Platinenbodens 13 abstützen, geradeso wie es bei den Platinen 1, an denen die Rollenstrupfe 3 (Figur 1) hängen, der Fall ist. Im Hinblick darauf, dass die Leisten 19 und 20 frei durch den Platinenboden 13 verschoben werden können, sind bei der zweiten Ausführungsform Stützen 29 für das Brett 6 (Figur 4) vorgeschen, auf denen das Brett ruht, wenn es sich in seiner untersten Position befindet.In the first embodiment according to Figure 2, the board 6 hangs in its lowermost position on the boards 14, which are supported on the top of the board bottom 13, just as it does with the boards 1, on which the roller brackets 3 (Figure 1) hang Case is. in the In view of the fact that the strips 19 and 20 can be freely moved through the board base 13, supports 29 for the board 6 (FIG. 4) are provided in the second embodiment, on which the board rests when it is in its lowest position.

Die Figuren 5a bis 5d geben schematisch wieder, wie bei der zweiten Ausfürhrungsform die vier möglichen Übergänge zwischen den beiden Positionen des Brettes 6 ermöglicht werden. Die Steuernadel 16 nimmt dabei zwei Stellungen ein: eine erste Stellung, in der die Leisten 19, 20 seitlich verbogen werden (Figuren 5a und 5c), und eine zweite Stellung, in der die Leisten 19 oder 20 gerade bleiben, also nicht verbogen sind (Figuren 5b und 5d). Im Falle verbogener Leisten 19 und 20 können die Messer 15 nicht hinter die hakenförmigen Nasen 21 greifen, und das Brett 6 bleibt unten auf den Stützen 29 (Figur 5a), oder die freien Messer 15 können nicht hinter die hakenförmigen Nasen 21 eingreifen, und jene Messer 15, die bereits in die Nasen 21 einhaken, tragen weiterhin die Leisten 19 oder 20 oder das Brett 6, sodass es beispielsweise absenken kann (Figur 5c). Falls die Leisten gerade bleiben, können bestimmte Messer 15 das Brett 6 z. B. nach oben hin mitnehmen (Figur 5b), oder es können andere Messer 15 das Brett 6 übernehmen, sodass es oben stehenbleibt (Figur 5d).FIGS. 5a to 5d schematically show how the four possible transitions between the two positions of the board 6 are made possible in the second embodiment. The control needle 16 assumes two positions: a first position in which the strips 19, 20 are bent laterally (FIGS. 5a and 5c), and a second position in which the strips 19 or 20 remain straight, i.e. are not bent ( Figures 5b and 5d). In the case of bent strips 19 and 20, the knives 15 cannot reach behind the hook-shaped lugs 21, and the board 6 remains on the supports 29 below (FIG. 5a), or the free knives 15 cannot engage behind the hook-shaped lugs 21, and those Knives 15, which already hook into the lugs 21, continue to carry the strips 19 or 20 or the board 6, so that it can lower, for example (FIG. 5c). If the strips remain straight, certain knives 15, the board 6 z. B. take upwards (Figure 5b), or other knives 15 can take over the board 6, so that it stops at the top (Figure 5d).
