Description

Webmaschineloom
Technisches GebietTechnical field
Die Erfindung betrifft eine Webmaschine gemäss Oberbegriff gemäss Anspruches 1.The invention relates to a weaving machine according to the preamble of claim 1.
Stand der TechnikState of the art
Webmaschinen der eingangs genannten Art sind mehrfach bekannt, so beispielsweise aus der DE 23 02 949. Diese Webmaschine weist eine Webstelle auf, der eine Breithaltevorrichtung für die herzustellende Warenbahn nachgeordnet ist. Die Breithaltevorrichtung enthält eine Umlenkkante für die Warenbahn, gegen die ein über die ganze Breite der Warenbahn reichender schwimmend angeordneter freidrehbarer Rundstab vorgespannt ist. Nachteilig ist jedoch, dass der Rundstab in einer Ausnehmung eines Maschinengestells angeordnet ist, die einen Schlitz ent- hält, der eine einlaufende und eine auslaufende Umlenkkante für die Warenbahn bildet. Die Warenbahn muss also in den Schlitz eingeführt, um den Rundstab geführt und über die zweite Umlenkkante an dem Schlitz wieder herausgeführt werden. Die Vorspannung, mit der der Rundstab gegen die Umlenkkanten gedrückt wird, wird durch den Zug an der Warenbahn an der Abzugsvorrichtung der Web- maschine bestimmt. Diese Ausbildung des Breithalters weist den Nachteil auf, dass das Einführen der Warenbahn durch den Schlitz in die Ausnehmung, das Umschlingen des Rundstabes und Ausführen der Warenbahn aus der Ausnehmung sehr kompliziert und umständlich ist. Dies nicht nur für das Einrichten der Webmaschine sondern insbesondere auch bei der Behebung in einer etwaigen Störung in der Webmaschine.Weaving machines of the type mentioned at the outset are known several times, for example from DE 23 02 949. This weaving machine has a weaving station, which is followed by a spreading device for the web to be produced. The spreader device contains a deflecting edge for the web against which a floating, freely rotatable round rod, which extends over the entire width of the web, is biased. However, it is disadvantageous that the round bar is arranged in a recess in a machine frame which contains a slot which forms an incoming and an outgoing deflection edge for the material web. The material web must therefore be inserted into the slot, guided around the round bar and led out again via the second deflection edge at the slot. The pretension with which the round bar is pressed against the deflection edges is determined by the tension on the web on the take-off device of the weaving machine. This design of the spreader has the disadvantage that the insertion of the material web through the slot into the recess, the looping of the round rod and the execution of the material web from the recess is very complicated and cumbersome. This is not only for setting up the weaving machine, but in particular also for the removal of any malfunction in the weaving machine.
Darstellung der ErfindungPresentation of the invention
Aufgabe der Erfindung ist es, eine Webmaschine der eingangs genannten Art zu verbessern, so dass die erwähnten Nachteile nicht mehr auftreten.The object of the invention is to improve a weaving machine of the type mentioned at the outset so that the disadvantages mentioned no longer occur.
Die Aufgabe wird bei der eingangs genannten Webmaschine durch die kennzeichnenden Merkmale des Anspruches 1 gelöst. Dadurch, dass der Rundstab mittels über seine Länge verteilten Magneten gegen die Umlenkkante vorgespannt wird, kann die Anordnung des Rundstabes in einer Ausnehmung mit einem Schlitz entfallen und der Rundstab liegt frei zugänglich auf der Warenbahn. Er muss auch nicht mehr mittels der Abzugskraft der Warenbahn gegen die Umlenkkante ge- drückt werden, sondern dies geschieht aufgrund der Magnetkraft, die den Rundstab gegen die Umlenkkante vorspannt. Durch diese freie Anordnung des Rundstabes auf der Warenbahn kann der Rundstab zwecks Einstellarbeiten und/oder Reparaturen vom Maschinengestell abgenommen werden, so dass die Warenbahn jederzeit frei zugänglich ist. Ausserdem liefern die über die Länge des Rundstabes verteilten Magnete eine über die ganze Länge gleichmässige Anpresskraft.The object is achieved in the loom mentioned at the outset by the characterizing features of claim 1. In that the round bar is biased against the deflection edge by means of magnets distributed over its length, the arrangement of the round rod in a recess with a slot can be omitted and the round rod is freely accessible on the web. It also no longer has to be pressed against the deflection edge by means of the pulling force of the material web, but rather this is due to the magnetic force which prestresses the round bar against the deflection edge. Through this free arrangement of the round bar on the web, the round bar can be removed from the machine frame for adjustment work and / or repairs, so that the web is freely accessible at all times. In addition, the magnets distributed over the length of the round rod provide a uniform contact force over the entire length.
Vorteilhafte Ausgestaltungen der Webmaschine sind in den abhängigen Ansprüchen 2 bis 9 beschrieben.Advantageous embodiments of the loom are described in the dependent claims 2 to 9.
Die Magnete zur Vorspannung des Rundstabes dienenden Magnete können gemäss Anspruch 2 Elektromagnete sein. Diese haben den Vorteil, dass sie einerseits ein- und ausgeschaltet werden können, wodurch das Abnehmen des Rundstabes erleichtert wird. Andererseits kann die Feldstärke der Magnete mit Hilfe des Stromes in weiten Grenzen eingestellt werden, wodurch sich die Breithaltevorrichtung optimal auf das Gewebe und die Herstellungsart einstellen lässt. Besonders einfach ist jedoch eine Ausbildung der Webmaschine nach Anspruch 3, wonach die Magnete Permanentmagnete sind, die einen besonders einfachen Aufbau gewährleisten und auch dann wirksam sind, wenn kein Antriebstrom vorhanden ist.The magnets for biasing the round bar magnets can be electromagnets according to claim 2. These have the advantage that they can be switched on and off on the one hand, which makes it easier to remove the round rod. On the other hand, the field strength of the magnets can be adjusted within wide limits with the aid of the current, as a result of which the spreading device can be optimally adjusted to the fabric and the type of manufacture. However, a design of the weaving machine according to claim 3 is particularly simple, according to which the magnets are permanent magnets, which ensure a particularly simple construction and are also effective when no drive current is present.
Nach Anspruch 4 ist die Anpresskraft der Magnete gösser als die von einer Abzugsvorrichtung auf die Warenbahn ausgeübte Abzugskraft. Gegebenenfalls kann es zweckmässig sein nach Anspruch 5 Stützrollen vorzusehen, die mindestens an den Enden des Rundstabes angreifen und die Anpressung unterstützen. In die- sem Falle kann die Anpresskraft der Magnete gegebenenfalls auch kleiner sein als die Abzugskraft der Abzugsvorrichtung. Es kann zweckmässig sein, dass die Stützrollen gegen den Rundstab vorgespannt sind. Zur Erleichterung der Montage und der Einstellung sowie Wartung der Webmaschine können die Stützrollen auch ausschwenkbar sein.According to claim 4, the pressing force of the magnets is greater than the pulling force exerted on the web by a pulling device. If necessary, it can be useful to provide support rollers according to claim 5, which act at least on the ends of the round rod and support the pressure. In this case, the contact pressure of the magnets may also be less than the pulling force of the pulling device. It may be appropriate for the support rollers to be biased against the round bar. To facilitate assembly and the adjustment and maintenance of the weaving machine, the support rollers can also be swung out.
Um den Antrieb des Rundstabes durch die durchlaufende Warenbahn zu verbes- sem, ist es vorteilhaft, den Rundstab mit einer die Reibung erhöhenden Oberfläche zu versehen. So kann der Rundstab gemäss Anspruch 6 beispielsweise mit einer gummielastischen Ummantlung versehen sein, oder gemäss Anspruch 7 mit einer sandpapierartigen Ummantelung. Gemäss Anspruch 8 kann der Rundstab mit einer wendelartig profilierten Ummantelung versehen sein, wobei die wendel- artige Profilierung an beiden Hälften des Rundstabes gegenläufig ausgerichtet ist. Ein solcher Rundstab wirkt zweckmässigerweise mit einer glatten Umlenkkante zusammen und dient dazu, die durchlaufende Gewebebahn nach beiden Seiten zu strecken.In order to improve the drive of the round bar by the continuous material web, it is advantageous to provide the round bar with a surface that increases the friction. For example, the round bar can be provided with a rubber-elastic sheathing, or according to claim 7 with a sandpaper-like sheathing. According to claim 8, the round rod can be provided with a helically profiled sheathing, the helical profile being oriented in opposite directions on both halves of the round rod. Such a round rod expediently interacts with a smooth deflection edge and serves to stretch the continuous fabric web on both sides.
Besonders wirkungsvoll ist auch eine Ausgestaltung der Webmaschine nach Anspruch 9, wonach die Umlenkkante mit Rippen versehen ist, die - in Laufrichtung der Warenbahn gesehen, beidseits der Mittellinie schräg nach aussen verlaufen. In diesem Falle weist der Rundstab zweckmässigerweise keine wendelartig profilierte Ummantelung auf.Also particularly effective is an embodiment of the weaving machine according to claim 9, according to which the deflection edge is provided with ribs which - seen in the running direction of the web, run obliquely outwards on both sides of the center line. In this case, the round rod expediently does not have a helically profiled casing.

Wege zur Ausführung der ErfindungWays of Carrying Out the Invention
Die Figur 1 zeigt in schematischer Darstellung eine Webmaschine im Ausschnitt. Kettfäden 2 bilden ein Webfach 4, in das ein Schussfaden 6 eingetragen wird. Der Schussfaden 6 wird dann mittels eines Webblattes 8 an der Warenanschlagkante 10 angeschlagen.Figure 1 shows a schematic representation of a loom in detail. Warp threads 2 form a shed 4 into which a weft thread 6 is inserted. The Weft thread 6 is then attached to the fabric stop edge 10 by means of a reed 8.
Der Warenanschlagkante 10 ist eine Breithaltevorrichtung 12 nachgeschaltet, die eine Umlenkkante 14 aufweist, gegen die die hergestellte Warenbahn 16 mittels eines Rundstabes 18 angepresst wird. Der aus ferromagnetischem Material bestehende Rundstab 18 wird mittels Magneten 20 gegen die Umlenkkante 14 ge- presst, so dass die Warenbahn 16 über die Umlenkkante 14 geführt am Rundstab 18 zur Anlage gebracht wird, so dass die von einer Abzugsvorrichtung 22 einge- triebene Warenbahn 16 den Rundstab 18 in Drehung versetzt. Der Rundstab ist auf einem Maschinengestell 24 schwimmend angeordnet und frei drehbar. Mehrere über die Länge des Rundstabes angeordnete Magnete, die am Maschinengestell 24 befestigt sind, sorgen für die notwendige Anpresskraft. Die Anpresskraft ist grösser als die auf die Warenbahn ausgeübte Abzugskraft der Abzugsvorrichtung.The goods stop edge 10 is followed by a spreading device 12 which has a deflection edge 14 against which the fabric web 16 produced is pressed by means of a round rod 18. The round rod 18 made of ferromagnetic material is pressed against the deflection edge 14 by means of magnets 20, so that the web 16 guided over the deflection edge 14 is brought into contact with the round rod 18, so that the web 16 driven by a take-off device 22 den Round rod 18 set in rotation. The round bar is arranged floating on a machine frame 24 and freely rotatable. Several magnets arranged over the length of the round rod and fastened to the machine frame 24 ensure the necessary contact pressure. The contact pressure is greater than the pulling force of the pulling device exerted on the web.
Der Rundstab 18 besteht im vorliegenden Beispiel aus einem ferromagnetischen Kern 26, der von einer Ummantelung 28 umgeben ist, die aus gummielastischem Werkstoff besteht. Anstelle einer gummielastischen Ummantelung kann auch eine andere Ummantelung vorgesehen sein, die den Reibungswiderstand zwischen der Warenbahn 16 und dem Rundstab 18 erhöht. Eine solche Ummantelung kann beispielsweise aus Sandpapier bestehen.The round rod 18 in the present example consists of a ferromagnetic core 26 which is surrounded by a sheath 28 which is made of rubber-elastic material. Instead of a rubber-elastic sheathing, another sheathing can also be provided, which increases the frictional resistance between the web 16 and the round rod 18. Such a covering can consist, for example, of sandpaper.
Die mit dem Rundstab 18 zusammenwirkende Umlenkkante 14 ist gemäss Figur 2 mit Rippen 30 versehen, die in Laufrichtung der Warenbahn 16 gesehen beidseits der Mittellinie 32 entgegengesetzt schräg nach aussen verlaufen.The deflecting edge 14 cooperating with the round rod 18 is provided according to FIG. 2 with ribs 30 which, seen in the direction of travel of the web 16, run obliquely outwards on both sides of the center line 32.
Die Figur 3 zeigt einen Rundstab 18a, der mit einer wendelartig profilierten Ummantelung 28a versehen ist, die wendelartige Rippen 34 aufweist, welche an beiden Hälften des Rundstabes 18a gegenläufig ausgerichtet sind. Ein solcher Rund- stab 18a wirkt zweckmässigerweise mit einer glatten Umlenkkante 14 zusammen, um die durchlaufende Warenbahn quer zur Längsrichtung zu strecken. Wie in Figur 1 gestrichelt angedeutet, können dem Rundstab mindestens an seinen Enden, gegebenenfalls auch über seine Länge verteilt, Stützrollen 36 zugeordnet sein. Die Stützrollen 36 sind jeweils über einen aus- und einschwenkbar am Maschinengestell 24 angeordneten Ausleger 38 angeordnet. Die Ausleger 38 enthalten ein Langloch 40 für die Achse 42 der Stützrolle 36. Auf die Achse 42 wirken Federn 44 zur Vorspannung der Stützrollen 36 gegen den Rundstab 18. FIG. 3 shows a round rod 18a which is provided with a helically profiled casing 28a which has helical ribs 34 which are oriented in opposite directions on both halves of the round rod 18a. Such a round rod 18a expediently interacts with a smooth deflection edge 14 in order to stretch the continuous material web transversely to the longitudinal direction. As indicated by dashed lines in FIG. 1, support rollers 36 can be assigned to the round rod at least at its ends, possibly also distributed over its length. The support rollers 36 are each arranged on a boom 38 which can be swung out and in on the machine frame 24. The arms 38 contain an elongated hole 40 for the axis 42 of the support roller 36. Springs 44 act on the axis 42 for prestressing the support rollers 36 against the round rod 18.
