Um Materialbahnen, die aus zwei diametral entgegengesetzten Richtungen zugeführt werden, in einer einzigen nachgeordneten Maschine verarbeiten zu können, oder um Papierbahnen, die aus einer gleichen Richtung kommen, zwei verschiedenen Maschinen zur Weiterverarbeitung zuführen zu können, sind Wendestangenapparate entwickelt worden, bei denen die Wendestangen zwischen zwei Arbeitsstellungen bewegbar sind, die jeweils eine Umlenkung der Materialbahn um 90° in entgegengesetzte Richtungen bewirken.In order to be able to process material webs fed from two diametrically opposite directions in a single downstream machine, or to be able to feed paper webs coming from the same direction to two different machines for further processing, turning bar apparatuses have been developed in which the turning bars be moved between two working positions, each causing a deflection of the web by 90 ° in opposite directions.
Ein derartiger Wendestangenapparat ist aus
Es sind zwar auch Wendestangenapparate bekannt, bei denen die Wendestangen durch eine 180°-Drehung um eine zur von den Achsen der Tragspindeln und der Wendestangen definierten Ebene parallele Achse von einer Arbeitsstellung in die andere umschaltbar sind. Eine solche Wendestangenanordnung erfordert jedoch oberhalb oder unterhalb dieser Ebene ausreichend Platz, um die Umschaltbewegung durchführen zu können.Although there are also known Wendestangenapparate in which the turning bars through a 180 ° rotation about an axis parallel to the axes of the support spindles and the turning bars defined axis from one working position to another are switchable. However, such a turning bar assembly requires above or below this level sufficient space to perform the switching movement can.

Der Erfindung liegt die Aufgabe zugrunde, eine Wendevorrichtung mit einer einfach und sicher schwenkbaren Wendestange zu schaffen.The invention has for its object to provide a turning device with a simple and safe pivoting turning bar.
Die Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale der Ansprüche 1 oder 2 gelöst.The object is achieved by the characterizing features of claims 1 or 2.
Ein mit der Erfindung erzielbarer Vorteil besteht insbesondere darin, dass sich der mechanische Aufbau der Wendevorrichtung vereinfacht, da eine gelenkige Verbindung des zweiten Längsendes der Wendestange mit dem Gestell entfällt. Es ist daher weder eine zweite Tragspindel noch Mittel zum Steuern von deren Bewegung erforderlich. Die Durchführung der Druckluftzufuhrleitung durch das die Wendestange mit dem Gestell verbindende Gelenk erlaubt einen insbesondere in vertikaler Richtung äußerst kompakten Aufbau; darüber hinaus ist es möglich, auf eine verschleiß- oder verletzungsgefährdete flexible Rohrleitung zum Heranführen der Druckluft an die Wendestange zu verzichten.An advantage achievable with the invention is, in particular, that the mechanical structure of the turning device is simplified, since a hinged connection of the second longitudinal end of the turning bar with the frame is eliminated. Therefore, neither a second supporting spindle nor means for controlling its movement is required. The implementation of the compressed air supply line through the joint connecting the turning bar with the frame allows an extremely compact especially in the vertical direction construction; In addition, it is possible to dispense with a wear-prone or vulnerable flexible pipe for bringing the compressed air to the turning bar.
Wenn die Wendestange zum Umlenken von Materialbahnen wechselnder Breite eingesetzt wird, ist es wünschenswert, die Ausdehnung des Oberflächenbereichs des Mantels der Wendestange, auf der Blasluft zum Bilden eines Luftkissens unter der umzulenkenden Materialbahn austritt, auf die Breite der Materialbahn begrenzen zu können. Zu diesem Zweck ist vorzugsweise wenigstens ein Kolben, der den druckluftgespeisten Innenraum axial begrenzt, in der Wendestange axial verschiebbar.When the turning bar is used for deflecting webs of varying width, it is desirable to increase the extension of the surface area of the web Mantels of the turning bar, emerges on the blown air to form an air cushion under the material to be deflected web, to limit the width of the web can. For this purpose, preferably at least one piston, which limits the compressed air-fed interior axially, in the turning bar axially displaceable.
Da das freie Ende der Wendestange nicht zum Anschließen der Druckluftzufuhrteitung benötigt wird, kann an diesem freien Ende vorteilhaft ein Stellelement zum Einstellen der Position des wenigstens einen Kolbens aus der Wendestange herausgeführt sein. Dieses Stellelement kann z. B. die Form eines Rändelrades oder einer Kurbel zum Drehen einer Gewindestange haben, die sich in Längsrichtung durch die Wendestange erstreckt und deren Gewinde mit einer Gewindebohrung des Kolbens kämmt.Since the free end of the turning bar is not needed to connect the Druckluftzufuhrteitung, advantageously at this free end an adjusting element for adjusting the position of the at least one piston can be led out of the turning bar. This actuator can, for. B. have the shape of a knurled wheel or a crank for rotating a threaded rod which extends in the longitudinal direction through the turning bar and the thread meshes with a threaded bore of the piston.
Der Schließkörper, der zum selektiven Schließen jeweils einer Gruppe von Löchern des Mantels der Wendestange dient, ist vorzugsweise als Hohlzylinder ausgebildet, wobei der wenigstens eine Kolben innerhalb des Hohlzylinders verschiebbar ist. Diese Anordnung ermöglicht es, den Schließkörper und den wenigstens einen Kolben unabhängig voneinander zu bewegen.The closing body, which serves for selectively closing a respective group of holes of the jacket of the turning bar, is preferably designed as a hollow cylinder, wherein the at least one piston is displaceable within the hollow cylinder. This arrangement makes it possible to move the closing body and the at least one piston independently.
Wenn der wenigstens eine Kolben an dem mit dem Gelenk verbundenen Längsende der Wendestange angeordnet ist, so ist es notwendig, die Druckluft, mit der der Innenraum der Wendestange gespeist wird, durch diesen Kolben hindurch zuzuführen. Zu diesem Zweck ist im Innern der Wendestange ein Abschnitt der Druckluftzufuhrleitung als Rohrabschnitt ausgebildet, der den Kolben durchquert.If the at least one piston is arranged at the longitudinal end of the turning bar connected to the joint, then it is necessary to supply the compressed air, with which the interior of the turning bar is fed, through this piston. For this purpose, a portion of the compressed air supply line is formed as a pipe section in the interior of the turning bar, which passes through the piston.
Das Gestell weist zwei Anschläge zum Festlegen der Endpositionen der Schwenkbewegungsfreiheit auf, die vorzugsweise justierbar sind.The frame has two stops for setting the end positions of the pivoting movement freedom, which are preferably adjustable.
Ferner ist zweckmäßigerweise wenigstens eine Fixiereinrichtung zum Fixieren der Wendestange in jeweils einer Endposition der Schwenkbewegungsfreiheit vorgesehen.Furthermore, at least one fixing device for fixing the turning bar is expediently provided in each case in an end position of the pivoting movement freedom.
Diese Fixiereinrichtung umfasst zweckmäßigerweise einen mit dem Gestell verbundenen Riegel zum Eingreifen an einem Vorsprung der Wendestange. Einer einfachen Ausgestaltung zufolge ist der Riegel um eine zur Längsachse der Wendestange senkrechte Achse schwenkbar.This fixing device expediently comprises a bolt connected to the frame for engaging a projection of the turning bar. According to a simple embodiment, the bolt is pivotable about an axis perpendicular to the longitudinal axis of the turning bar.
Der Schließkörper, der zum selektiven Verschließen jeweils einer Gruppe von Löchern des Mantels vorgesehen ist, ist vorzugsweise um die Längsachse der Wendestange zwischen seinen zwei Stellungen drehbar. Dieses Merkmal erlaubt im Vergleich zu der aus
Um ein schnelles Umschalten der Wendevorrichtung zwischen den zwei Arbeitspositionen der Wendestange zu ermöglichen, kann ein Linearstellglied, insbesondere ein Pneumatikzylinder, zum Antreiben der Schwenkbewegung vorgesehen werden.In order to enable a quick switching of the turning device between the two working positions of the turning bar, a linear actuator, in particular a pneumatic cylinder, can be provided for driving the pivoting movement.
