Description

Hierzu 1 Blatt Zeichnungen1 sheet of drawings

Die Erfindung betrifft eine Vorrichtung gemäß dem Oberbegriff des Anspruchs.The invention relates to a device according to the preamble of the claim.

Aus der GB-PS 12 88 846 ist eine Vorrichtung der eingangs bezeichneten Gattung bekannt Hier wird die von einer Wickelrolle abgezogene Bahn über eine verschwenkbare Umlenkkante geführt um unterschiedliche Spannungen in der Bahn zu vergleichmäßigen bzw. zu beseitigen. Besonders bei hohen Bahnlaufgeschwindigkeiten, wie sie z. B. in modernen Druckmaschinen anzutreffen sind, besteht die Gefahr, daß sich die Umlenkkante erwärmt Außerdem ist eine Abnützung der Umlenkkante nicht zu vermeiden.From GB-PS 12 88 846 a device of the type mentioned is known Here is the from a winding roll pulled web over a pivotable deflection edge guided around different To equalize or eliminate tensions in the web. Especially at high web speeds, how they z. B. are found in modern printing machines, there is a risk that the deflection edge heated In addition, wear and tear on the deflecting edge cannot be avoided.

Aufgabe der Erfindung ist es eine Vorrichtung der eingangs genannten Gattung zu schaffen, bei der eine übermäßige Erwärmung der Umlenkkante vermieden wird und diese auswechselbar ist.The object of the invention is to create a device of the type mentioned at the outset, in which a excessive heating of the deflection edge is avoided and this is exchangeable.

Diese Aufgabe wird durch die Anwendung der Merkmale des Kennzeichens des Anspruchs gelöstThis object is achieved by applying the features of the characterizing part of the claim

Nachstehend ist ein Ausführungsbeispiel der Erfindung anhand der Zeichnung näher erläutert. Es zeigtAn exemplary embodiment of the invention is explained in more detail below with reference to the drawing. It shows

F i g. 1 schematisiert einen Schnitt durch einen für die Erfindung wesentlichen Teil einer Bahnführung in einer Rollenrotationsdruckmaschine, hier unmittelbar hinter der Wickelrolle mit dem erfindungsgemäßen Umlenkblech und dessen Halterungsvorrichtung,F i g. 1 schematically shows a section through a part of a web guide which is essential for the invention Web-fed rotary printing machine, here directly behind the winding roll with the deflector plate according to the invention and its mounting device,

Fig.2 die Draufsicht auf die Vorrichtung gemäß Fig. 1.2 shows the top view of the device according to Fig. 1.

In F i g. 1 ist ein Ausschnitt aus einer Bahnführung 1 einer Rollenrotationsdruckmaschine gezeigt, bei der eine Bahn 2 von einer nicht dargestellten Wickelrolle kommend über Umlenkwalzen 3 geführt wird. Gegen die zwischen zwei der Umlenkwalzen 3 in gestrichelt dargestellter Weise gespannte Bahn 2 ist ein Umlenkblech 4 anstellbar, das mit seiner sich über die gesamte Breite der Bahn erstreckenden Umlenkkante 5 an der Bahn 2 anliegt. Das Umlenkblech 4 ist an Halterungsarmen 6 befestigt, die drehfest an einer Achse 7 angeordnet sind. Die Achse 7 ist an ihren Enden in Lagerböcken 8 und 9 gelagert die im Rahmen einer Rollenrotationsdruckmaschine angeordnet sind. Am Lagerbock 8 ist eine Platte 10 befestigt die von einer von Hand zu betätigenden Stellschraube 11 durchsetzt ist Die Stellschraube 11 wirkt auf ein Hebelelement 12, das drehfest mit der Achse 7 verbunden ist.In Fig. 1 shows a section from a web guide 1 of a web-fed rotary printing press, in which a Web 2 coming from a winding roll (not shown) is guided over deflection rollers 3. Against the web 2 stretched between two of the deflecting rollers 3 in the manner shown in dashed lines is a deflecting plate 4 adjustable, with its deflecting edge 5 extending over the entire width of the web Lane 2 is present. The deflection plate 4 is fastened to holding arms 6, which are arranged in a rotationally fixed manner on an axis 7 are. The axis 7 is mounted at its ends in bearing blocks 8 and 9 which are part of a web-fed rotary printing press are arranged. A plate 10 is attached to the bearing block 8, which can be operated by hand Adjusting screw 11 is penetrated The adjusting screw 11 acts on a lever element 12, which is non-rotatable is connected to the axis 7.

Im Betrieb ist das Umlenkblech 4 mit seiner Umlenkkante 5 gegen die Bahn 2 gedrückt, so daß diese aus der gestrichelten Normallage ausgelenkt ist. Der Anpreßdruck ist mittels der Stellschraube 11 regulierbar, indem durch Auslenken des Hebelelementes 12 die Halterungsarme 6 und damit auch das Umlenkblech 4 entsprechend ausgelenkt werden. Während die Bahn 2 überIn operation, the deflection plate 4 is pressed with its deflecting edge 5 against the web 2, so that this out of the dashed normal position is deflected. The contact pressure can be regulated by means of the adjusting screw 11 by by deflecting the lever element 12, the holding arms 6 and thus also the deflection plate 4 accordingly be deflected. While the web 2 over

Patentanspruch:Claim: Vorrichtung zum Ausgleich unterschiedlicher Bahnspannungen für eine von einer Wickelrolle abgezogene Bahn, die über eine verstellbare, sich über die Breite der Bahn erstreckende Umlenkkante geführt wird, dadurch gekennzeichnet, daß die Umlenkkante (5) an der Stirnseite eines Umlenkbleches (4) angeordnet ist und daß die Umlenkkante (5) gekühlt und hierzu ein im Umlenkblech (4) vorgesehener Kühlraum an einen Kühlmittelkreislauf angeschlossen istDevice for balancing different web tensions for one drawn off a winding roll Web that is guided over an adjustable deflecting edge that extends over the width of the web is, characterized in that the deflection edge (5) on the end face of a deflection plate (4) is arranged and that the deflecting edge (5) is cooled and for this purpose one is provided in the deflecting plate (4) Cold room is connected to a coolant circuit die Umlenkkante 5 gleitet werden unterschiedliche Spannungen ausgeglichen.the deflecting edge 5 slides different tensions are balanced. Das Umlenkblech 4 dient als Trägerelement für verschieden geformte oder elastisch verformbar Umlenkkanten. The deflection plate 4 serves as a carrier element for differently shaped or elastically deformable deflection edges. Die durch Verschleiß unbrauchbar gewordenen Umlenkkanten können somit leicht ausgewechselt werden.The deflection edges, which have become unusable due to wear, can thus be easily replaced. Die Umlenkkante ist gekühlt, wozu im Umlenkblech 4 ein an einen Kühlmittelkreislauf angeschlossener Kühlraum vorgesehen istThe deflecting edge is cooled, including a cooling space connected to a coolant circuit in the deflecting plate 4 is provided
