Description

Die Erfindung betrifft, eine Vorrichtung zum Aufspannen von Kettfäden an einer Kettfadeneinziehmaschine, mit einem im Wesentlichen senkrecht und neben einer Fadenabtrennvorrichtung zum Abtrennen der Kettfäden angeordneten Rahmen für aufgespannte Kettfäden, wobei die Fadenabtrennvorrichtung in einem ersten Randbereich des Rahmens ortsfest angeordnet ist und wobei der Rahmen im ersten Randbereich in Richtung einer Senkrechten quer zu einer durch die aufgespannten Kettfäden gebildeten Ebene geführt und mit der Fadenabtrennvorrichtung in Richtung einer Hauptachse verschiebbar verbunden ist und der Rahmen in einem zweiten Randbereich fahrbar gelagert und für eine Verschiebung in Richtung einer Hauptachse quer und parallel zu der Ebene geführt ist.The invention relates to a device for tensioning warp threads on a warp threading machine, with one essentially vertically and next to a thread cutting device to separate the warp threads arranged frame for stretched Warp threads, the thread cutting device in one first edge region of the frame is arranged stationary and the frame in the direction of a in the first edge region Perpendicular to one through the stretched warp threads formed level and performed with the thread cutting device is slidably connected in the direction of a main axis and the frame is movably supported in a second edge area and for a displacement in the direction of a major axis transversely and is parallel to the plane.

Aus der EP 0 446 326 ist eine gattungsgemässe Vorrichtung bekannt, bei welcher der Rahmen mit den aufgespannten Kettfäden längsverschiebbar in einem Grundgestell eingehängt ist, das die gesamte Kettfadeneinziehmaschine überspannt. An demselben Grundgestell ist auch die Fadenabtrennvorrichtung ortsfest angebracht. So kann der Rahmen mit den aufgespannten Kettfäden vor der Fadenabtrennvorrichtung parallel zu der aufgespannten Kettfadenschar verschoben werden, wobei die Fadenabtrennvorrichtung die einzelnen Kettfäden nach und nach zum Einziehen in das Geschirr einer Webmaschine abtrennt.EP 0 446 326 describes a generic device known in which the frame with the stretched warp threads suspended longitudinally in a base frame is that spans the entire warp threading machine. On The thread cutting device is the same base frame fixed attached. So the frame with the stretched Warp threads in front of the thread cutting device parallel to of the open warp thread coulter are moved, whereby the thread separating device and the individual warp threads after being pulled into a harness to pull it into the harness.

Ein Nachteil dieser bekannten Vorrichtung ist insbesondere darin zu sehen, dass sowohl die Fadenabtrennvorrichtung, wie auch der Rahmen am Grundgestell gelagert sind und ihre Position zueinander über die relative Lage zu dem Grundgestell definiert ist. Das bedeutet, dass letztlich die Lage der Ebene der aufgespannten Kettfäden wie auch die Lage der Fadenabtrennvorrichtung durch Führungen und Tragelemente gewährleistet ist, die am Grundgestell befestigt sind. Solche Führungen und Tragelemente sind teilweise lang, deformierbar und weisen Spiel auf. So ist die Lage der Fadenabtrennvorrichtung vor den Kettfäden nur mit Einschränkungen genau. Das bedeutet, dass die Lage um so genauer ist, desto steifer und schwerer die genannten Träger und Führungen ausgebildet sind.A disadvantage of this known device is in particular to see that both the thread cutting device, such also the frame are stored on the base frame and their position to each other about the relative position to the base frame is defined. That means that ultimately the location of the Level of the stretched warp threads as well as the position of the thread cutting device guaranteed by guides and support elements which are attached to the base frame. Such Guides and support elements are sometimes long, deformable and have play. This is the position of the thread cutting device in front of the warp threads only with restrictions. This means that the more precise the position, the stiffer and heavier trained the carriers and guides are.

Eine weitere Vorrichtung ist aus EP 0 541 268 bekannt. Dort wird der Rahmen ebenfalls gegen eine ortsfest angeordnete Fadenabtrennvorrichtung bewegt. Der Rahmen ist in einem ersten, oberen Randbereich angelehnt geführt. Diese Vorrichtung beinhaltet, neben der Einschränkung der Verwendbarkeit für bestimmte, zur Anwendung der Ansaugtechnik geeigneten Garnen, den Nachteil, dass der Rahmen so geführt ist, dass das sichere Einfahren der Fadenschicht, d.h. der abzutrennenden Kettfäden in das Fadenabtrennorgan bzw. in die Fadenabtrennvorrichtung nicht in jedem Falle einwandfrei gewährleistet ist.Another device is known from EP 0 541 268. There the frame is also arranged against a stationary one Thread cutting device moved. The frame is in a first, upper edge area ajar. This device includes, in addition to the limitation of usability for certain suitable for the application of the suction technology Yarn, the disadvantage that the frame is guided so that the safe retraction of the thread layer, i.e. the one to be separated Warp threads in the thread separating member or in the thread separating device not guaranteed in every case is.

Die Erfindung, wie sie in den Ansprüchen gekennzeichnet ist, löst deshalb die Aufgabe, eine einfache und leichte Vorrichtung der genannten Art zu schaffen bei der die abzutrennenden Kettfäden und die Fadenabtrennvorrichtung möglichst genau zueinander liegen.The invention as characterized in the claims therefore solves the task of a simple and easy device of the type mentioned in which to be separated Warp threads and the thread cutting device as precisely as possible lie to each other.

Dies wird, gemäss der Kombination der Merkmale des unabhängigen Anspruchs 1, dadurch erreicht, dass der Rahmen in einem Randbereich fahrbar gelagert und für eine Verschiebung in einer Richtung geführt ist und in einem weiteren Randbereich mit der Fadenabtrennvorrichtung in derselben Richtung verschiebbar und direkt verbunden ist. Vorzugsweise ist der Rahmen an mindestens drei beanstandeten Stellen, die in den Ecken eines Dreiecks liegen, geführt, und zwar an zwei Stellen gegen die Schwerkraft und seitliche Verschiebung in einer Richtung und an mindestens einer Stelle nur gegen seitliche Verschiebung in einer Richtung. Diese letzte Stelle liegt immer an oder in unmittelbarer Nähe zum Fadenabtrennorgan bzw. zur Fadenabtrennvorrichtung. Dies gilt auch für eine weitere mögliche Stelle zur Führung gegen seitliche Verschiebung. Bevorzugte Weiterbildungen der erfindungsgemässen Vorrichtung ergeben sich aus den abhängigen Ansprüchen.This is, according to the combination of the characteristics of the independent Claim 1, achieved in that the frame in one Bordered area mobile and for a shift is guided in one direction and in a further edge area with the thread cutting device in the same direction slidably and directly connected. Preferably, the Framework in at least three objections, which in the Corners of a triangle lie, guided, in two places against gravity and lateral displacement in one Direction and at least at one point only against the side Unidirectional shift. This last place is always on or in the immediate vicinity of the thread cutting element or to the thread cutting device. This also applies to another possible place to guide against lateral Shift. Preferred developments of the inventive Device result from the dependent claims.

Die durch die Erfindung erreichten Vorteile sind insbesondere darin zu sehen, dass der abzutrennende Kettfaden immer genau an der richtigen Stelle vor der Fadenabtrennvorrichtung zu liegen kommt. Dies unabhängig davon ob ein Grundgestell durch das Gewicht des Rahmens örtlich verformt ist oder ob der Rahmen verzogen ist. So kann einerseits die Abtrennung des Kettfadens sicher durchgeführt werden und dies mit einer Vorrichtung, die nicht besonders schwer und steif auszubilden ist.The advantages achieved by the invention are particular to be seen in the fact that the warp thread to be separated is always exactly in the right place in front of the thread cutting device comes to rest. This regardless of whether a base frame is locally deformed by the weight of the frame or whether the frame is warped. On the one hand, the separation of the warp thread can be carried out safely and this with a device that is not particularly heavy and stiff is to be trained.

Im folgenden wird die Erfindung anhand eines Beispiels und mit Bezug auf die beiliegenden Figuren näher erläutert. Es zeigen:

  • Figur 1 eine perspektivische Darstellung der Vorrichtung und
  • Figur 2 einen Schnitt durch die Vorrichtung
  • The invention is explained in more detail below using an example and with reference to the accompanying figures. Show it:
  • Figure 1 is a perspective view of the device and
  • Figure 2 shows a section through the device
  • Fig. 1 zeigt eine erfindungsgemässe Vorrichtung mit einem Rahmen 1 zum Aufspannen von Kettfäden, welche hier nicht gezeigt sind. Der Rahmen 1 besteht im wesentlichen aus zwei horizontalen Trägern 2, 3 und zwei vertikalen Stützen 4, 5. Vor den horizontalen Trägern 2, 3 und an diesen in an sich bekannter Weise befestigt sind Führungsschienen 6, 7 für die Kettfäden, so dass diese nebeneinander in einer Fläche oder Ebene liegen. Am oberen horizontalen Träger 2 ist ferner eine weitere Führungsschiene 8 befestigt, die zur Führung des Rahmens 1 dient. Am unteren horizontalen Träger 3 oder möglicherweise auch an den Stützen 4, 5 sind zwei Rollen 9, 10 beweglich gelagert. Diese laufen und stützen sich auf einer ortsfesten Schiene 11. In einem ersten, oberen Randbereich 12 des Rahmens 1 ist neben dem Rahmen 1 eine Fadenabtrennvorrichtung 13 ortsfest gelagert. Diese ist an einem hier nicht gezeigten Hauptgestell der Einziehmaschine in an sich bekannter Weise befestigt. Die Fadenabtrennvorrichtung 13 weist auf dem Gehäuse 14 als Führungsrollen ein Rollenpaar 15 auf, in dem die Schiene 8 durchlaufen kann. In einem unteren zweiten Randbereich 16 des Rahmens 1 sind die bereits genannten Rollen 9, 10 angeordnet, die den Rahmen 1 fahrbar lagern. Über einen Verbindungsteil 28 zur Fadenabtrennvorrichtung 13 ist ebenfalls eine weitere Rolle 19 ortsfest gelagert, auf der sich eine hier nur teilweise dargestellte Klemmschiene 27 seitlich abstützt. Am Rahmen 1 sind weitere Vorrichtungen, wie z.B. ein Bürstenbaum 17 zum Spannen der Kettfäden usw. angebracht. Solche Vorrichtungen sind aber an sich bekannt und für die vorliegende Erfindung nicht bedeutsam.Fig. 1 shows an inventive device with a Frame 1 for stretching warp threads, which are not shown here are. The frame 1 consists essentially of two horizontal beams 2, 3 and two vertical supports 4, 5. In front of the horizontal beams 2, 3 and on them in themselves are known guide rails 6, 7 are attached for Warp threads so that they are side by side in one area or Level. On the upper horizontal support 2 is also one further guide rail 8 attached to guide the Frame 1 is used. At the bottom horizontal beam 3 or possibly on the supports 4, 5 there are two rollers 9, 10 movably mounted. These run and are based on one stationary rail 11. In a first, upper edge area 12 of the frame 1 is next to the frame 1, a thread cutting device 13 stationary. This is on one here main frame of the drawing machine not shown in itself attached in a known manner. The thread cutting device 13 has a pair of rollers on the housing 14 as guide rollers 15 on, in which the rail 8 can pass. In a lower one second edge region 16 of the frame 1 are already called rollers 9, 10 arranged, the frame 1 mobile to store. Via a connecting part 28 to the thread cutting device 13 another roller 19 is also mounted in a stationary manner, on which one is only partially shown here Clamping rail 27 is supported laterally. There are more on frame 1 Devices such as a brush tree 17 for clamping the Warp threads etc. attached. Such devices are on known and not significant for the present invention.

    Fig. 2 zeigt wiederum dieselben Elemente wie Fig. 1, die deshalb auch mit gleichen Bezugszeichen versehen sind. Diese werden aber hier nicht nochmals einzeln erwähnt. Allerdings ist das Gehäuse 14 der Fadenabtrennvorrichtung 13 nur noch teilweise dargestellt. Dafür erkennt man hier besser, dass die Schiene 8 im Rollenpaar 15 bzw. zwischen den Rollen 15 geführt ist. Hier ist aber eine Kettfadenschar 18 eingezeichnet, die durch die Führungsschiene 6, 7 positioniert ist.Fig. 2 again shows the same elements as Fig. 1, the are therefore provided with the same reference numerals. This are not mentioned again here individually. Indeed is the housing 14 of the thread cutting device 13 only partially shown. But you can see better here that the rail 8 in the pair of rollers 15 or between the rollers 15 is led. Here, however, a warp thread group 18 is shown, positioned by the guide rail 6, 7 is.

    Die Wirkungsweise der erfindungsgemässen Vorrichtung ist dabei wie folgt:

  • In an sich bekannter Weise wird eine Kettfadenschar 18 vor den Führungsschienen 6, 7 aufgespannt, beispielsweise durch den Bürstenbaum 17 weiter nachgespannt und durch Schienen, wie die Klemmschiene 27 (Fig. 2) befestigt, d.h. auf die Führungsschiene 6, 7 geklemmt. Dazu kann der Rahmen 1 durch Verschiebung auf der Schiene 11 in eine Stellung gebracht werden, in der das Rollenpaar 15 an einem Ende der Schiene 8 liegt. Dabei liegt die Klemmschiene 27 unten an der Rolle 19 an. Die Kettfadenschar 18 spannt dabei eine Fläche oder Ebene 20 auf, die parallel zu Hauptachsen 21,22 der Schienen 8 und 11 liegt. Zum Abtrennen der einzelnen Kettfäden, wird der Rahmen 1 in Richtung der Hauptachsen 21, 22 bewegt. Dabei ist er im Randbereich 16 durch die Rollen 9, 10 auf der Schiene 11 gegen Verschiebungen quer zur Schiene 11 oder deren Hauptachse 22 in zwei Richtungen entsprechend Pfeilen 23, 24 geführt.
  • The mode of operation of the device according to the invention is as follows:
  • In a manner known per se, a warp thread sheet 18 is stretched in front of the guide rails 6, 7, for example further tightened by the brush tree 17 and fastened by rails such as the clamping rail 27 (FIG. 2), ie clamped onto the guide rail 6, 7. For this purpose, the frame 1 can be brought into a position by displacement on the rail 11, in which the pair of rollers 15 lies at one end of the rail 8. The clamping rail 27 rests on the roller 19 at the bottom. The warp thread sheet 18 spans a surface or plane 20 which is parallel to the main axes 21, 22 of the rails 8 and 11. To separate the individual warp threads, the frame 1 is moved in the direction of the main axes 21, 22. It is guided in the edge region 16 by the rollers 9, 10 on the rail 11 against displacements transversely to the rail 11 or its main axis 22 in two directions according to arrows 23, 24.
  • Im Randbereich 12 ist der Rahmen 1 durch das ortsfeste Rollenpaar 15 und die Schiene 8 nur gegen Verschiebungen in Richtung des Pfeiles 23 geführt. Im Randbereich 16 ist der Rahmen 1 durch die ortsfeste Rolle 19 zusätzlich in der Richtung des Pfeiles 23 geführt. Der Rahmen 1 wird dabei durch sein Eigengewicht an die Rolle 19 gedrückt. Die Rollen 9,10 sind mit dem Rahmen vorzugsweise über Gelenke 30 schwenkbar bzw. kippbar verbunden. Diese Gelenke sind dabei vorzugsweise an der dem Fadenabtrennorgan zugewandten Seite des Schwerpunktes des Rahmens angeordnet, so dass der Rahmen 1 mit der resultierenden, im wesentlichen horizontalen Komponente seines Eigengewichtes auf der Rolle 19 sicher aufliegt.In the edge region 12, the frame 1 is due to the stationary pair of rollers 15 and the rail 8 only against displacements in Direction of arrow 23 out. In the edge area 16 is the Frame 1 by the fixed roller 19 in addition in the Direction of arrow 23 out. The frame 1 will be there pressed against the roller 19 by its own weight. The roles 9, 10 are preferably connected to the frame via joints 30 pivotally or tiltably connected. These joints are there preferably on the side facing the thread separating member arranged the center of gravity of the frame so that the frame 1 with the resulting, essentially horizontal component its own weight rests securely on the roller 19.

    Mit anderen Worten, ist der Rahmen 1 mindestens an drei Stellen A, B, C und wahlweise zusätzlich an einer Stelle D gelagert oder geführt. An den Stellen B und C ist der Rahmen längs der Hauptachse 22 geführt. An Stellen A und D ist der Rahmen in Richtung des Pfeiles 23 geführt. Der grosse Vorteil dieser Lösung liegt darin, dass eine Führung für den Rahmen 1 sehr nahe an der Fadenabtrennvorrichtung 13 liegt und dass der Rahmen im Punkt A und vorzugsweise auch in Punkt D, in unmittelbarer Nähe zum Fadenabtrennorgan, quer zur Ebene 20 besonders genau geführt ist. Damit ist auch gewährleistet, dass die Kettfäden genau in das Fadenabtrennorgan einlaufen. Die Kettfadenschar 18 weist in der Nähe der Fadenabtrennvorrichtung 13 einen konstanten Abstand 25 auf, der hier z.B. zwischen der Kettfadenschar 18 und einer äusseren Begrenzung 26 des Gehäuses 14 angegeben ist, in Wirklichkeit aber zu einem hier nicht gezeigten, aber an sich bekannten Abtrennorgan garantiert ist. So sind die Kettfäden zum Abtrennen auch dann genau positioniert, wenn beispielsweise die Schiene 8 gebogen ist. Es ist klar, dass beispielsweise das Rollenpaar 15 bei geeigneter Ausbildung auch Schwerkräfte aufnehmen könnte, so dass dann der Rahmen 1 an der Fadenabtrennvorrichtung 13 mindestens teilweise angehängt wäre. Die Rolle 19 führt zusammen mit der Klemmschiene 27 den Rahmen 1 insbesondere dann genau, wenn die Rolle 9, 10 auf der Schiene 11, insbesondere auch wegen der schwenkbaren bzw. kippbaren Verbindung der Rollen 9, 10 zum Rahmen 1, keine genaue Führung in Richtung des Pfeiles 23 gewährleisten können, oder wenn der Rahmen 1 gewisse Verformungen zulässt.In other words, the frame 1 is at least three Positions A, B, C and optionally additionally at a position D stored or led. At points B and C is the frame guided along the main axis 22. At positions A and D is the Frame guided in the direction of arrow 23. The big advantage this solution is that a guide for the Frame 1 is very close to the thread cutting device 13 and that the frame in point A and preferably also in Point D, in the immediate vicinity of the thread cutting element, across to level 20 is guided particularly precisely. This also ensures that the warp threads are exactly in the thread separating organ enter. The warp thread sheet 18 has near the Thread cutting device 13 at a constant distance 25, which here e.g. between the warp thread sheet 18 and an outer Boundary 26 of the housing 14 is indicated, in reality but to a not shown here, but in itself known separation organ is guaranteed. So are the warp threads positioned for separation even when, for example the rail 8 is bent. It is clear that for example the pair of roles 15 with suitable training also Could absorb gravity, so that then the frame 1 the thread cutting device 13 at least partially attached would. The roller 19 leads together with the clamping rail 27 the frame 1 in particular when the roller 9, 10 on the rail 11, especially because of the pivotable or tiltable connection of the rollers 9, 10 to the frame 1, do not ensure accurate guidance in the direction of arrow 23 can, or if the frame 1 certain deformations allows.

    Weitere Vorteile der Erfindung umfassen die Möglichkeit, dass auf ein Maschinengestell zur Führung des Rahmens, welches mindestens die doppelte Kettbaumbreite aufweisen müsste, gänzlich verzichtet werden kann. Dies bedeutet eine wesentlich verbesserte Zugänglichkeit der Vorrichtung und erlaubt dem Weber das bauseitige Installieren von Hebevorrichtungen zum Abrüsten und zwar in weitgehend beliebiger Anordnung. Zudem können dank der erfindungsgemässen Führung des Rahmens die Herstellungskosten für solche Vorrichtungen erheblich gesenkt werden.Further advantages of the invention include the possibility of that on a machine frame to guide the frame, which should be at least twice the warp beam width, can be dispensed with entirely. This means an essential one improved accessibility of the device and allowed for the weaver to install lifting devices on site for dismantling and in a largely arbitrary arrangement. In addition, thanks to the leadership of the invention Frame the manufacturing cost of such devices significantly be lowered.
