Description

Vorrichtung zur Herstellung eines gekrümmten Bandes, insbesondere eines gekrümmten flachen Leitungsverbundes Device for producing a curved band, in particular a curved flat line assembly
Die Erfindung betrifft eine Vorrichtung zur Herstellung eines gekrümmten Bandes, insbesondere eines gekrümmten flachen Leitungsverbundes, bestehend aus einer einer Webeinrichtung nachgeschalteten Antriebseinrichtung mit rotierenden Klemmelementen.The invention relates to a device for producing a curved band, in particular a curved flat line assembly, consisting of a drive device with rotating clamping elements connected downstream of a weaving device.
Aus DE 198 16 666 A 1 ist es bekannt, Bänder als Gewebeverbund mit einer Krümmung in der Gewebeebene herzustellen. Hier wird auch eine Vorrichtung zur Herstellung gekrümmter Bänder mit einer rotierenden Abzugseinrichtung beschrieben, in der als Abzugseinrichtung Kegelwalzen eingesetzt sind. Die Kegelwalzen ziehen die Kettfäden im Bereich mit dem größeren Durchmesser schneller ab als im Bereich mit dem kleineren Durchmesser, so dass eine Krümmung in Richtung der Seite mit dem kleineren Durchmesser entsteht. Um den Krümmungsradius zu ändern, werden in der Schrift zwei Varianten genannt.From DE 198 16 666 A 1 it is known to produce ribbons as a composite fabric with a curvature in the plane of the fabric. A device for producing curved strips with a rotating take-off device is also described here, in which tapered rollers are used as the take-off device. The tapered rollers draw off the warp threads faster in the area with the larger diameter than in the area with the smaller diameter, so that there is a curvature in the direction of the side with the smaller diameter. In order to change the radius of curvature, two variants are mentioned in the font.
Die erste Variante besteht darin, dass die Oberfläche der Kegelwalzen aus Lamellen aufgebaut ist und der Durchmesser durch unterschiedliches Verschieben der Lamellen an beiden Seiten der Walze unterschiedlich eingestellt wird. In der zweiten Variante ist ein Revolver-Walzenmagazin vorgesehen, in dem Kegelwalzen für beide Krümmungssinne und die unterschiedlichen Krümmungsradien vorhanden sind.The first variant is that the surface of the tapered rollers is made up of lamellae and the diameter is set differently by moving the lamellae differently on both sides of the roller. In the second variant, a turret roller magazine is provided in which tapered rollers are provided for both senses of curvature and the different radii of curvature.
Diese Lösungen weisen den Nachteil auf, dass die Lamellenkegelwalze und das Revolver-Walzenmagazin aufwendig gestaltet sind und dadurch hohe Herstellungskosten verursachen. Durch die komplizierte Gestaltung dieser Baugruppen und die hohe Teilezahl nimmt zugleich die Störanfälligkeit des Gesamtsystems zu und seine Verfügbarkeit ab. Nachteil ist ebenso der hohe Platzbedarf des Walzenmagazins und seine begrenzte Speicherkapazität, so dass nur eine geringe Variationsbreite der Krümmungen herstellbar ist.These solutions have the disadvantage that the lamellar tapered roller and the turret roller magazine are designed in a complex manner and thus cause high production costs. Due to the complicated design of these assemblies and the large number of parts, the susceptibility to malfunction of the overall system increases and increases Availability. Another disadvantage is the high space requirement of the roller magazine and its limited storage capacity, so that only a small variation in the curvature can be produced.
Der Erfindung liegt die Aufgabe zugrunde, eine flexible, kostengünstige, platzsparende und mit einem weiten Anwendungsspektrum versehene Vorrichtung zu schaffen.The invention has for its object to provide a flexible, inexpensive, space-saving device with a wide range of applications.
Erfindungsgemäß wird die Aufgabe gelöst, indem mindestens zwei Abzugsrollen in einem Gestell angeordnet sind, von denen mindestens eine Abzugsrolle angetrieben ist.According to the invention the object is achieved in that at least two take-off rollers are arranged in a frame, of which at least one take-off roller is driven.
Das Gestell ist um eine zur Ebene des Bandes senkrechte Achse schwenkbar. Die Schwenkachse des Gestells ist zusätzlich noch quer zur Bewegungsrichtung des Bandes verschiebbar. Die Abzugsrollen können entsprechend dem Dickenprofil des Bandes vorteilhaft profiliert sein. Die nicht angetriebenen Abzugsrollen (Andruckrollen) können aus Segmenten unterschiedlichen Durchmessers bestehen, die auf eine feste Achse aufgesteckt sind. Schließlich können die Abzugsrollen über einen Freilauf verfügen.The frame can be pivoted about an axis perpendicular to the plane of the belt. The pivot axis of the frame can also be moved transversely to the direction of movement of the belt. The take-off rollers can advantageously be profiled according to the thickness profile of the belt. The non-driven take-off rollers (pressure rollers) can consist of segments of different diameters, which are attached to a fixed axis. Finally, the take-off rollers can have a freewheel.
Die Erfindung wird anhand des nachstehenden Ausführungsbeispiels näher erläutert. In der zugehörigen Zeichnung zeigen:The invention is explained in more detail using the exemplary embodiment below. In the accompanying drawing:
Fig. 1 die schematische Darstellung der erfindungsgemäßen Vorrichtung und Fig. 2 eine Draufsicht der Vorrichtung nach Fig. 1.1 shows the schematic representation of the device according to the invention and FIG. 2 shows a top view of the device according to FIG. 1.
Die Vorrichtung (Fig. 1 ) enthält eine Abzugsrolle 1 und eine Andruckrolle 2, zwischen denen die Kettfäden in Form von Einzelleitungen 3 verlaufen. In die Abzugsrolle 1 greift der Rollenantrieb 4 ein.The device (Fig. 1) contains a take-off roller 1 and a pressure roller 2, between which the warp threads run in the form of individual lines 3. The roller drive 4 engages in the take-off roller 1.
Abzugsrolle 1 , Andruckrolle 2 und Rollenantrieb 4 bilden die Abzugseinrichtung. Diese ist an einem Schwenkgestell 5 montiert, welches um die Schwenkachse Z mit Hilfe eines Hydraulikzylinders 6 (Fig. 2) schwenkbar ist. Außerdem ist aas Schwenkgestell in der Webebene und senkrecht zur Laufrichtung der Einzelleitungen 3 auf einem Gleitbett 7 verschiebbar.Take-off roller 1, pressure roller 2 and roller drive 4 form the take-off device. This is mounted on a swivel frame 5, which with the swivel axis Z With the help of a hydraulic cylinder 6 (Fig. 2) is pivotable. In addition, the swivel frame can be displaced on a sliding bed 7 in the weaving plane and perpendicular to the running direction of the individual lines 3.
Mit dieser Anordnung kann die Schwenkachse Z des Schwenkgestells 5 an die Kante des abzuziehenden Leitungsverbundes gestellt werden, die bei der Herstellung des Bogens den zugehörigen Innenradius bilden soll. Mit dem Grad des Ausschwenkens der Abzugseinrichtung wird der Krümmungsradius bestimmt. Ist die Ausschwenkung 00 zieht die Abzugseinrichtung den Leitungsverbund wie eine herkömmliche Abzugseinrichtung ab, und es entsteht ein gerades Band.With this arrangement, the pivot axis Z of the swivel frame 5 can be placed on the edge of the line assembly to be removed, which is to form the associated inner radius during the production of the bend. The radius of curvature is determined by the degree of pivoting of the trigger device. If the swiveling-out is 00, the pull-off device pulls off the line assembly like a conventional pull-off device, and a straight band is produced.
Soll ein Bogen entstehen, dann werden bei beizubehaltender Drehzahl der Abzugsrollen 1 , 2 diese zusätzlich um die Schwenkachse Z geschwenkt. Dadurch wird an den von der Schwenkachse Z entfernt liegenden Einzelleitungen eine größere Länge abgezogen, als an den der Schwenkachse Z näher liegenden Einzelleitungen. Es entsteht eine Krümmung.If an arc is to be produced, the take-off rollers 1, 2 are additionally pivoted about the pivot axis Z while maintaining the rotational speed. As a result, a greater length is subtracted from the individual lines lying away from the pivot axis Z than from the individual lines closer to the pivot axis Z. There is a curvature.
Der Gesamtbetrag ω einer einzelnen Schwenkung ist begrenzt. Zur Erzielung von Krümmungen mit größerem Winkel als ω werden einzelne Krümmungsabschnitte aneinander gereiht.The total amount ω of a single swivel is limited. To achieve curvatures with a larger angle than ω, individual curvature sections are lined up.
Dazu wird nach Erreichen der größtmöglichen Einzelschwenkung ω die Drehzahl der Abzugsrolle so erhöht, dass eine schnelle Rückschwenkung der Antriebseinrichtung ohne das Entstehen von Stauchungen im Band erfolgen kann. Nach dieser Rückstellung beginnt der beschriebene Vorgang erneut. Zur Verbesserung dieser Rücklaufeigenschaften können die Abzugsrollen in Segmente aufgeteilt werden, die - jedes Segment für sich - einen Freilaufmechanismus besitzen, der bei der Rückschwenkung der möglichen Entstehung von Stauchungen entgegenwirkt. BezugszeichenFor this purpose, the rotational speed of the take-off roller is increased so that the largest possible individual swivel ω is achieved so that the drive device can swivel back quickly without the occurrence of compression in the belt. After this reset, the process described begins again. To improve these return properties, the take-off rollers can be divided into segments which - each segment by itself - have a freewheel mechanism which counteracts the possible formation of compression when swiveling back. reference numeral
