Schaberklingen werden beispielsweise in Papiermaschinen eingesetzt, um die sich im Betrieb drehenden Walzenoberflächen durch Andrücken der Schaberklingen zu reinigen und sauberzuhalten. Die jeweilige Schaberklinge ist dabei in einen Schaberhalter eingeschoben und zum Zwecke einer Fixierung in diesem Schaberhalter und zum Schutz gegen ein Herausfallen aus dem Schaberhalter auf ihrer Unterseite mit Formfedern oder Nieten versehen. Diese können beispielsweise in einem Abstand von 70 cm an der Schaberklinge angeordnet sein, wobei die Schaberklinge selbst eine Länge von beispielsweise 10 m und eine Breite von 3 cm aufweisen kann.Scraper blades are used, for example, in paper machines to clean and keep clean the rotating roll surfaces during operation by pressing the scraper blades. The respective scraper blade is inserted into a scraper holder and provided for the purpose of fixing in this scraper holder and to protect against falling out of the scraper holder on its underside with shaped springs or rivets. These can be arranged, for example, at a distance of 70 cm on the doctor blade, wherein the doctor blade itself can have a length of for example 10 m and a width of 3 cm.
Schaberklingen können auch in anderen Produktionsmaschinen verwendet werden, in denen Walzen- oder Trommeloberflächen saubergehalten werden müssen.Scraper blades can also be used in other production machines in which roll or drum surfaces must be kept clean.
Im Betrieb der jeweiligen Produktionsmaschine werden die Schaberklingen, die aus Kunststoffen, Metallen oder Verbundmaterialien bestehen, durch Abrieb verschlissen und durch den Belag, der sich auf den Walzenoberflächen ausbildet, mehr oder weniger stark verschmutzt. Durch derartige Schmutzablagerungen an den Schaberklingen kann es zu einem Abheben der Schaberklinge und damit zu einer Funktionseinschränkung oder gar einem Funktionsausfall der Schaberklingenvorrichtung kommen. Des Weiteren können Schmutzteilchen beispielsweise auf die laufende Papierbahn fallen und Störungen in Form eines Abrisses der Papierbahn verursachen. Um diese Nachteile zu vermeiden, ist es notwendig, eine verschmutzte Schaberklinge aus der jeweiligen Produktionsmaschine herauszunehmen, außerhalb der Produktionsmaschine zu reinigen und dann wieder in die jeweilige Produktionsmaschine einzusetzen oder durch eine neue Schaberklinge zu ersetzen.During operation of the respective production machine, the doctor blades, which are made of plastics, metals or composite materials, are worn down by abrasion and more or less contaminated by the coating that forms on the roll surfaces. By such dirt deposits on the doctor blades can lead to a lifting of the doctor blade and thus to a functional limitation or even a malfunction of the doctor blade device. Furthermore, dirt particles may, for example, fall onto the running paper web and cause disturbances in the form of a tear of the paper web. In order to avoid these disadvantages, it is necessary to remove a soiled doctor blade from the respective production machine, to be cleaned outside the production machine and then reinserted into the respective production machine or replaced by a new doctor blade.

Der Schaberklingeneinführtrichter 7 weist Schrägwände 7a und 7b auf. Diese haben im Eingangsbereich des Schaberklingeneinführtrichters 7 einen relativ großen Abstand voneinander und verlaufen in Einführrichtung 14 der Schaberklinge aufeinander zu. Aufgrund des großen Abstandes der Schrägwände 7a und 7b im Eingangsbereich des Schaberklingeneinführtrichters 7 wird ein Fangen des vorderen Endbereiches einer einzuführenden Schaberklinge erleichtert. In Einführrichtung 14 wird die Schaberklinge danach durch die Schrägwände 7a und 7b des Schaberklingeneinführtrichters 7 gezielt in eine vorgegebene Höhenposition geführt, in welcher der vordere Endbereich der in den Schaberhalter 1 einzuführenden Schaberklinge in den vorgesehenen Bereich zwischen den Haltefingern 4 und der Deckplatte 3 eingeführt bzw. eingeschoben werden kann.The doctor
Die Verwendung eines an der Deckplatte 3 des Schaberhalters 1 befestigten Schaberklingeneinführtrichters 7 als Schaberklingeneinführhilfe ist insbesondere deshalb von Vorteil, weil der Schaberhalter 1 und die von der Schaberklinge 5 zu reinigende Walze innerhalb der jeweiligen Produktionsmaschine angeordnet sind, lediglich durch ein Fenster, welches sich im Bereich der Vorderwand der Produktionsmaschine befindet, zugänglich sind und von diesem Fenster beabstandet sind. Der vordere Endbereich der einzuführenden Schaberklinge muss von einer Bedienperson in den schmalen Bereich zwischen den Haltefingern 4 und der Deckplatte 3 eingeführt werden, wobei die Bedienperson aus baulichen Gründen und aus Sicherheitsgründen einen Mindestabstand vom Schaberhalter einhalten muss. Folglich kann er die Schaberklinge beim Einführen derselben in den schmalen Bereich zwischen den Haltefingern und der Deckplatte nicht an deren vorderem Endbereich festhalten, so dass der vordere Endbereich der Schaberklinge während deren Transports in Richtung des genannten schmalen Bereiches zu Schwingungen neigt. Aufgrund der Verwendung des genannten, an der Deckplatte des Schaberhalters befestigten Schaberklingeneinführtrichters kann der vordere Endbereich der einzuführenden Schaberklinge vergleichsweise leicht in den genannten schmalen Bereich zwischen den Haltefingern und der Deckplatte geleitet werden.The use of an attached to the
