Description

Die Erfindung betrifft eine Schaberklingenhaltevorrichtung, welche ein Bodenteil, eine Deckplatte, ein Schwenklager, Fingervorrichtungen und mindestens einen zwischen dem Bodenteil und der Deckplatte positionierten Luftschlauch aufweist.The invention relates to a doctor blade holding device, which has a bottom part, a cover plate, a pivot bearing, finger devices and at least one positioned between the bottom part and the cover plate air hose.

Eine derartige Schaberklingenhaltevorrichtung kann beispielsweise in einer Papierfabrik im Rahmen der Papierherstellung oder in der Stahlindustrie verwendet werden. Sie dient zur Aufnahme einer Schaberklinge zwecks gleichmäßiger Anlage an eine rotierende Walze bzw. Rolle, um deren Oberfläche während des Betriebes zu reinigen. Eine derartige Walze kann eine Breite von mehreren Metern aufweisen. Die zur Reinigung einer solchen Walze vorgesehene Schaberklinge muss über die gesamte Länge der Walze möglichst gleichmäßig unter einem vorgegebenen Winkel an der Walze anliegen. Um dies zu erreichen, wird die Schaberklinge im Allgemeinen mit einem relativ großen Druck an die Walze angelegt.Such a doctor blade holding device can be used, for example, in a paper mill in papermaking or in the steel industry. It serves to receive a scraper blade for the purpose of even contact with a rotating roller or roller in order to clean the surface during operation. Such a roller may have a width of several meters. The scraper blade provided for cleaning such a roller must rest over the entire length of the roller as uniformly as possible at a predetermined angle to the roller. To accomplish this, the doctor blade is generally applied to the roller at a relatively high pressure.

Bei derartigen bekannten Schaberklingenhaltern kann die Deckplatte nach einem Lösen von einer oder mehreren Schrauben vom Bodenteil entfernt werden, beispielsweise um Servicearbeiten an der Schaberklingenhaltevorrichtung durchführen zu können. Bei diesen bekannten Schaberklingenhaltern besteht das Problem, dass der oder die Luftschläuche bei einem Entfernen der Deckplatte vom Bodenteil im Bodenteil verbleiben und dann im Rahmen eines zusätzlichen Arbeitsschrittes vom Bodenteil entfernt werden müssen. Dieser zusätzliche Arbeitsschritt ist in vielen Fällen aufgrund der baulichen Gegebenheiten der jeweiligen Papiermaschine umständlich. Beispielsweise muss eine Bedienperson unter Verwendung einer Leiter beim Vorliegen einer engen Einbausituation den Luftschlauch vom Bodenteil lösen. Dabei muss darauf geachtet werden, dass der Luftschlauch nach dem Lösen nicht unkontrolliert herunterfällt und Schäden verursacht oder selbst beschädigt wird, beispielsweise dadurch, dass er mit heißen Teilen der Papiermaschine in Kontakt gerät.In such known doctor blade holders, the cover plate can be removed after a release of one or more screws from the bottom part, for example, to perform service work on the doctor blade holding device. In these known doctor blade holders, there is the problem that when the cover plate is removed from the bottom part, the air tubing or tubes remain in the bottom part and then have to be removed from the bottom part within the scope of an additional work step. This extra step is in many Cases cumbersome due to the structural conditions of the respective paper machine. For example, an operator must use a ladder in the presence of a tight installation situation, the air hose from the bottom part to solve. Care must be taken to ensure that the air hose does not drop uncontrollably after loosening and causes damage or is itself damaged, for example, by being in contact with hot parts of the paper machine.

Bei anderen bekannten Schaberklingenhaltern sind der oder die Luftschläuche ohne Befestigung zwischen dem Bodenteil und der Deckplatte positioniert. Bei derartigen Schaberklingenhaltern können der oder die Luftschläuche bei einem Entfernen der Deckplatte vom Bodenteil unkontrolliert herabfallen, so dass auch hier Schäden auftreten können bzw. eine erhöhte Sorgfalt notwendig ist, um derartige Schäden zu vermeiden.In other known doctor blade holders or the air hoses are positioned without attachment between the bottom part and the cover plate. In such doctor blade holders or the air hoses can fall uncontrollably when removing the cover plate from the bottom part, so that here too damage may occur or increased care is necessary to prevent such damage.
