Description

Die Erfindung betrifft eine Schaberklingenhaltevorrichtung mit den im Oberbegriff des Anspruchs 1 angegebenen Merkmalen.The invention relates to a doctor blade holding device with the features specified in the preamble of claim 1.

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.

Aus der DE 31 36 085 A1 ist ein Schaber zum Abschaben eines Papiermaschinen- oder dergleichen Zylinders mit einer Schaberklinge, die in einem Halter gelagert ist, bekannt. Der Halter weist ein sich parallel zum Zylinder erstreckendes Haupttragstück zum Ausüben von Druck auf die an den Zylinder anzudrückende Schaberklinge, eine steife Tragplatte, die sich vom Tragstück in Richtung Zylinder erstreckt, eine unterhalb dieser Tragplatte und parallel zum Zylinder angebrachten Gelenkstab und einen Klingenhalter zur Aufnahme des Hinterendes der Schaberklinge, der sich vom Gelenkstab aus nach vorne zum Zylinder erstreckt, auf. Weiterhin ist ein mit einem Fluid gefüllter Balg vorgesehen, der sich zwischen der Tragplatte und dem von Gelenkplatten gebildeten Klingenhalter sowie zwischen dem Hinterende der Schaberklinge und dem Gelenkstab parallel zur Länge der Schaberklinge erstreckt.From DE 31 36 085 A1 a scraper for scraping a Papiermaschinen- or the like cylinder with a doctor blade, which is mounted in a holder known. The retainer includes a main support member extending parallel to the cylinder for applying pressure to the doctor blade to be pressed against the cylinder, a rigid support plate extending from the support toward the cylinder, a hinge rod mounted below the support plate and parallel to the cylinder, and a blade holder for receiving the rear end of the scraper blade, which extends from the hinge rod to the front of the cylinder, on. Furthermore, a fluid-filled bellows is provided which extends between the support plate and the blade holder formed by hinge plates and between the rear end of the doctor blade and the hinge rod parallel to the length of the doctor blade.

Aus der WO 93/21380 ist bereits eine Schaberklingenhaltevorrichtung bekannt, welche zwei Halteelemente aufweist. Zwischen die genannten Halteelemente ist ein erster Teil der Schaberklinge eingebracht. Der zweite Teil der Schaberklinge führt von den Halteelementen weg. Eines dieser Halteelemente ist eine Platte, die aus einer Vielzahl von Faserschichten besteht. Die Anzahl und die Orientierung dieser Faserschichten ist von den gewünschten Arbeitsbedingungen der Schaberklinge abhängig. Zur Einstellung und Veränderung des Druckes, mit welchem die Schaberklinge an der Walze anliegt, sind zwei pneumatische Schläuche vorgesehen, von denen sich - aus Sicht der Schaberklinge - einer vor und einer hinter einem Drehpunkt befindet. DerFrom WO 93/21380 a doctor blade holding device is already known, which has two holding elements. Between the said holding elements, a first part of the doctor blade is introduced. The second part of the doctor blade leads away from the holding elements. One of these retaining elements is a plate consisting of a plurality of fiber layers. The number and orientation of these fibrous layers depends on the desired working conditions of the doctor blade. To adjust and change the pressure with which the doctor blade abuts the roller, two pneumatic hoses are provided, of which - from the perspective of the doctor blade - one in front of and one behind a fulcrum. Of the

Drehpunkt ist im mittleren Bereich des Grundplatte vorgesehen. Durch geeignetes Aufpumpen bzw. Entleeren der Schläuche lässt sich der gewünschte Anpressdruck der Schaberklinge an die Walze einstellen. Weiterhin weist die bekannte Vorrichtung eine flexible Dichtung auf, die ein Einbringen von Staub und anderen Fremdkörpern verhindern soll. Da sich diese flexible Dichtung über die gesamte Länge der Walze erstrecken muss, ist deren Realisierung aufwendig. Hinzu kommt, dass wegen der beim Betrieb auftretenden hohen Temperaturen hitzebeständige Dichtungen verwendet werden müssen, beispielsweise Viton-Dichtungen. Dies ist mit sehr hohen Kosten verbunden.Fulcrum is provided in the central region of the base plate. By suitable inflating or emptying of the hoses, the desired contact pressure of the doctor blade can be adjusted to the roller. Furthermore, the known device has a flexible seal which is intended to prevent the introduction of dust and other foreign bodies. Since this flexible seal must extend over the entire length of the roller, the implementation is complicated. In addition, due to the high temperatures encountered during operation, heat resistant gaskets must be used, such as Viton gaskets. This is very expensive.

Aus der EP 1 186 703 A2 ist eine Schaberanordnung bekannt, welche einen Klingenträger und eine Schaberklinge aufweist. Der Klingenträger ist um eine Achse verschwenkbar an einem Klingenhalter angeordnet, wobei zwischen dem Klingenträger und dem Klingenhalter mindestens ein Druckelement angeordnet ist, welches unabhängig vom Druck selbstähnlich ist, d. h. seine grundlegende Form beibehält. Vorzugsweise ist auf beiden Seiten der Achse jeweils ein Druckelement angeordnet. Auch bei dieser Anordnung befindet sich die Achse im mittleren Bereich des Grundplatte bzw. Klingenhalters. Mittels der genannten Druckelemente, bei denen es sich um Schläuche handelt, kann der gewünschte Anpressdruck der Schaberklinge an die Walze eingestellt und auch durch Erzeugung eines geeigneten Gegendrucks ein Abheben der Schaberklinge von der Walze durchgeführt werden. Wird diese bekannte Schaberanordnung ohne eine Dichtung verwendet, dann ist ein häufiges Reinigen der Vorrichtung notwendig. Dies ist aber wegen der engen Einbausituation ungemein schwierig.From EP 1 186 703 A2 a scraper arrangement is known which has a blade carrier and a scraper blade. The blade carrier is pivotally mounted about an axis on a blade holder, wherein between the blade carrier and the blade holder at least one pressure element is arranged, which is self-similar regardless of the pressure, d. H. maintains its basic shape. Preferably, a pressure element is arranged on both sides of the axis. Also in this arrangement, the axis is in the central region of the base plate or blade holder. By means of said printing elements, which are tubes, the desired contact pressure of the doctor blade can be adjusted to the roller and also by raising a suitable back pressure, a lifting of the doctor blade of the roller can be performed. If this known scraper arrangement used without a seal, then a frequent cleaning of the device is necessary. However, this is extremely difficult because of the tight installation situation.

Der Erfindung liegt die Aufgabe zugrunde, eine Schaberklingenhaltevorrichtung anzugeben, bei der die vorstehend genannten Nachteile nicht auftreten.The invention has for its object to provide a doctor blade holding device in which the above-mentioned disadvantages do not occur.

Diese Aufgabe wird durch eine Schaberklingenhaltevorrichtung mit den im Anspruch 1 angegebenen Merkmalen gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den abhängigen Ansprüchen.This object is achieved by a doctor blade holding device having the features specified in claim 1. Advantageous embodiments and modifications of the invention will become apparent from the dependent claims.

Die Vorteile der Erfindung bestehen insbesondere darin, dass aufgrund der beanspruchten Ausbildung und Positionierung der Achse eine gesonderte Schmutz- bzw. Staubabdichtung entfallen kann. Das Drehlager dient in vorteilhafter Weise gleichzeitig als Schmutz- bzw. Staubabdichtung. Folglich ist eine Verwendung von aufwendigen und teueren Gummi- bzw. Viton-Dichtungen nicht notwendig.The advantages of the invention are in particular that due to the claimed training and positioning of the axis a separate dirt or dust seal can be omitted. The pivot bearing is advantageously used simultaneously as a dirt or dust seal. Consequently, a use of expensive and expensive rubber or Viton seals is not necessary.

Vorzugsweise ist die Deckplatte mit einem geschlitzten Vierkantrohr verbunden, innerhalb dessen das in einem Endbereich der Grundplatte vorgesehene Lagerrohr drehbar ist.Preferably, the cover plate is connected to a slotted square tube within which the provided in an end region of the base plate bearing tube is rotatable.

Mittels der im Anspruch 3 angegebenen Merkmale wird erreicht, dass die Deckplatte in einfacher Weise entfernt werden kann, so dass Reinigungsarbeiten innerhalb der Vorrichtung und ein Auswechseln des Luftschlauches erleichtert sind. Insbesondere ist es nicht notwendig, eine Vielzahl von Schrauben herauszudrehen, um die Deckplatte abnehmen zu können.By means of the features specified in claim 3 it is achieved that the cover plate can be removed in a simple manner, so that cleaning work within the device and replacement of the air hose are facilitated. In particular, it is not necessary to unscrew a plurality of screws in order to remove the cover plate can.

Ist die Grundplatte mit einem zur Aufnahme der Deckplatte vorgesehenen Schuh kontaktiert, wie er in den Ansprüchen 4 und 5 angegeben ist, dann ist die Führung der Deckplatte beim Einsetzen und Herausziehen verbessert. Weiterhin wird dadurch auch eine verbesserte Staub- und Schmutzabdichtung erreicht.If the base plate contacted with a provided for receiving the cover plate shoe, as indicated in the claims 4 and 5, then the guidance of the cover plate during insertion and withdrawal is improved. Furthermore, this also an improved dust and dirt seal is achieved.

Durch die Merkmale des Anspruchs 7 wird erreicht, dass im Innenbereich der Grundplatte befindliche Bauteile, insbesondere der pneumatische Schlauch, vor einem Kontakt mit den im Betrieb teilweise sehr heiß werdenden Begrenzungswänden der Grundplatte geschützt sind.Due to the features of claim 7 ensures that located in the interior of the base plate components, in particular the pneumatic hose, are protected from contact with the partially very hot in operation expectant boundary walls of the base plate.

Durch die Merkmale des Anspruches 8 wird erreicht, dass die Schaberklingenhaltevorrichtung mit nur einem Schlauch auskommt. Wird der Schlauch mit Luft gefüllt, dann führt dies je nach Luftdruck zu einem stärkeren Anpressen der Schaberklinge an die zu reinigende Walze. Dabei wird gleichzeitig eine Feder auseinandergezogen bzw. gespannt. Wird die Luft aus dem Schlauch abgelassen, dann erfolgt durch die sich wieder zusammenziehende bzw. entspannende Feder ein Abheben der Schaberklinge von der zu reinigenden Walze. Ein zweiter Schlauch, wie er bei den bisher bekannten Anordnungen vorgesehen ist, ist nicht notwendig. Die genannte Federrückstellung ist beispielsweise notwendig zum Wechseln der Schaberklinge.Due to the features of claim 8 it is achieved that the doctor blade holding device manages with only one hose. If the hose is filled with air, then this leads, depending on the air pressure, to a greater pressure of the doctor blade on the roller to be cleaned. At the same time a spring is pulled apart or stretched. If the air is drained from the hose, then the scraper blade is lifted off the roller to be cleaned by the spring which contracts or relaxes again. A second tube, as provided in the previously known arrangements, is not necessary. The said spring return is necessary, for example, to change the doctor blade.

Vorzugsweise bilden ein Teil der Deckplatte, das Vierkantrohr, die Grundplatte und der Schuh eine im wesentlichen staubdichte Einheit.Preferably, a part of the cover plate, the square tube, the base plate and the shoe form a substantially dustproof unit.

Weitere vorteilhafte Eigenschaften der Erfindung ergeben sich aus deren beispielhafter Erläuterung anhand der Figuren. Diese zeigen Skizzen einer Schaberklingenhaltevorrichtung gemäß zweier Ausführungsbeispiele der Erfindung.Further advantageous features of the invention will become apparent from the exemplification thereof with reference to the figures. These show sketches of a doctor blade holding device according to two embodiments of the invention.

Die in der Figur 1 dargestellte Schaberklingenhaltevorrichtung weist eine Grundplatte 6 auf, die im wesentlichen U-förmig ausgebildet ist und zwei kurze und eine lange Begrenzungswand aufweist. Im Endbereich einer der kurzen Begrenzungswände ist ein Lagerrohr 5 angeordnet, welches Bestandteil der Grundplatte ist. Das Lagerrohr 5 ist innerhalb eines geschlitzten Vierkantrohres 4 und um einen kleinen Winkel drehbar zu diesem gelagert.The doctor blade holding device shown in Figure 1 has a base plate 6 which is formed substantially U-shaped and has two short and one long boundary wall. In the end of one of the short boundary walls, a bearing tube 5 is arranged, which is part of the base plate. The bearing tube 5 is mounted within a slotted square tube 4 and rotatable about a small angle to this.

Das Vierkantrohr ist mit einer Deckplatte 2 fest verbunden, vorzugsweise mittels einer Vielzahl von Schraubverbindungen, die senkrecht zur Zeichenebene hintereinander angeordnet sind, in der Zeichnung aber nicht dargestellt sind. Die Deckplatte 2 besteht vorzugsweise aus Kohlefasermaterial und kann mehrere Kohlefaserschichten aufweisen. Dadurch ist die Deckplatte flexibel und kann sich an die Oberfläche der jeweils zu reinigenden Walze gut anpassen.The square tube is fixedly connected to a cover plate 2, preferably by means of a plurality of screw connections which are arranged perpendicular to the plane one behind the other, but are not shown in the drawing. The cover plate 2 is preferably made of carbon fiber material and may have multiple carbon fiber layers. As a result, the cover plate is flexible and can adapt well to the surface of each roller to be cleaned.

Im vorderen Endbereich der Deckplatte 2 sind mittels Schraubverbindungen 3a Fingervorrichtungen 3 an der Deckplatte befestigt, die ebenfalls senkrecht zur Zeichenebene hintereinander angeordnet sind. Zwischen der Deckplatte 2 und den Fingervorrichtungen 3 ist die Schaberklinge 1 eingebracht. Dieses Einbringen der Schaberklinge erfolgt vorzugsweise durch ein Einschieben in Axialrichtung. Da der hintere Endbereich der Schaberklinge mit einer Niete oder Feder 15 versehen ist, kann die Schaberklinge im Betrieb nicht in Richtung der zu reinigenden Walze herausgezogen werden.In the front end region of the cover plate 2, finger devices 3 are fastened to the cover plate by means of screw connections 3 a, which are also arranged one behind the other perpendicular to the plane of the drawing. Between the cover plate 2 and the finger devices 3, the doctor blade 1 is introduced. This introduction of the scraper blade is preferably carried out by insertion in the axial direction. Since the rear end portion of the doctor blade is provided with a rivet or spring 15, the doctor blade can not be pulled out in the direction of the roller to be cleaned during operation.

Um den jeweils gewünschten Anpressdruck der Schaberklinge an die Oberfläche der zu reinigenden Walze einzustellen, ist im Innenbereich der U-förmigen Grundplatte 6 ein pneumatischer Luftschlauch 14 vorgesehen. Dieser ist an seinem einen Ende mit einem Luftanschluss versehen, durch welchen Luft in den Schlauch gepresst werden kann und auch wieder Luft aus dem Schlauch ausgelassen werden kann. Das andere Ende des Schlauches 14 ist verschlossen. Zwischen dem Schlauch 14 und der langen Begrenzungswand der U-förmigen Grundplatte 6 ist eine Kunststoffeinlage 7 vorgesehen. Diese ist auf die Innenseite der Grundplatte lose eingelegt, aufgeklebt oder angeschraubt und verhindert, dass im Betrieb der Vorrichtung der Schlauch 14 mit einer möglicherweise heißen Begrenzungswand in Berührung kommt.In order to set the particular desired contact pressure of the doctor blade to the surface of the roller to be cleaned, a pneumatic air hose 14 is provided in the interior of the U-shaped base plate 6. This is provided at its one end with an air connection, through which air can be pressed into the hose and also air from the hose can be omitted. The other end of the tube 14 is closed. Between the tube 14 and the long boundary wall of the U-shaped base plate 6, a plastic insert 7 is provided. This is loosely inserted, glued or screwed on the inside of the base plate and prevents the hose 14 comes into contact with a possibly hot boundary wall during operation of the device.

Wird der Luftdruck im Schlauch 14 erhöht, dann dehnt sich dieser aus. Dies bewirkt, dass im Bereich des Schlauches 14 die Deckplatte 2 von der Grundplatte 6 weggedrückt wird. Dies wiederum hat zur Folge, dass die Schaberklinge, die im Bereich des vorderen Endes der Deckplatte an dieser befestigt ist, sich in Richtung des Pfeiles x bewegt bzw. in Richtung x gedrückt wird. Dadurch wird die Schaberklinge an die zu reinigende Walzenoberfläche angelegt und der gewünschte Anpressdruck über ein Druckregelventil eingestellt.If the air pressure in the hose 14 is increased, then this expands. This causes the cover plate 2 is pushed away from the base plate 6 in the region of the tube 14. This in turn has the consequence that the doctor blade, in the region of the front end of the cover plate this is fixed, moves in the direction of the arrow x and is pressed in the direction x. As a result, the doctor blade is applied to the roll surface to be cleaned and set the desired contact pressure via a pressure control valve.

Weiterhin ist im Innenbereich der U-förmigen Grundplatte 6 eine Feder 8 vorgesehen. Deren eines Ende ist mit der langen Begrenzungswand der Grundplatte 6 verbunden. Das andere Ende der Feder 8 ist an einem Schuh 10 befestigt, welcher zur Aufnahme des hinteren Endbereichs der Deckplatte 2 vorgesehen ist. Der Schuh bildet in einer Richtung senkrecht zur Zeichenebene eine Führungsschiene, innerhalb welcher die Deckplatte in Axialrichtung verschiebbar gelagert ist. Der Schuh ist mit einer Gleitfläche 11 versehen, die parallel zu einer Begrenzungswand 9 der U-förmigen Grundplatte angeordnet ist. Der Schuh 10 ist zusammen mit der Deckplatte relativ zur Grundplatte verschwenkbar. Diese Verschwenkbarkeit ist dadurch gegeben, dass in der Begrenzungswand 9 der Grundplatte in Radialrichtung verlaufende Langlöcher 13 vorgesehen sind, durch welche mit der Gleitfläche 11 des Schuhs verbundene Nieten 12 geführt sind.Furthermore, a spring 8 is provided in the interior of the U-shaped base plate 6. Whose one end is connected to the long boundary wall of the base plate 6. The other end of the spring 8 is fixed to a shoe 10, which is provided for receiving the rear end portion of the cover plate 2. The shoe forms in a direction perpendicular to the plane of a guide rail, within which the cover plate is mounted displaceably in the axial direction. The shoe is provided with a sliding surface 11, which is arranged parallel to a boundary wall 9 of the U-shaped base plate. The shoe 10 is pivotable together with the cover plate relative to the base plate. This pivotability is given by the fact that in the boundary wall 9 of the base plate in the radial direction extending slots 13 are provided, through which associated with the sliding surface 11 of the shoe rivets 12 are guided.

Wird der Luftdruck im Schlauch 14 erhöht, dann wird die Feder auseinandergezogen und der Schuh bewegt sich in der Zeichenebene nach rechts, so dass sich der Abstand des Schuhs von der langen Begrenzungswand der Grundplatte vergrößert.When the air pressure in the hose 14 is increased, the spring is pulled apart and the shoe moves to the right in the plane of the drawing, so that the distance of the shoe from the long boundary wall of the base plate increases.

Soll die Schaberklinge 1 wieder von der Walzenoberfläche abgehoben werden, beispielsweise zu einem Klingenwechsel, dann wird die Luft aus dem Schlauch 14 ausgelassen. Durch die sich dann wieder zusammenziehende Feder 8 wird der Schuh 10 in der Zeichenebene nach links in seine Ausgangsstellung zurückbewegt, so dass auch die Deckplatte 2 wieder in ihre Ausgangsstellung zurückgeschwenkt wird.If the doctor blade 1 is to be lifted off the roll surface again, for example, to a blade change, then the air is discharged from the hose 14. By then retracting spring 8 of the shoe 10 is moved back in the plane to the left to its original position, so that the cover plate 2 is pivoted back to its original position.

In der Figur 1 ist nach alledem eine neuartige Schaberklingenhaltevorrichtung gezeigt, welche keine zusätzliche elastische Staub- und Schmutzabdichtung benötigt. Dies wird im wesentlichen durch die beanspruchte spezielle Ausbildung und Anordnung der Schwenkebene der Schaberklingenhaltevorrichtung erreicht. Die Ausgestaltung der Schaberklingenhaltevorrichtung gemäß der Erfindung ermöglicht es weiterhin, mit nur einem Luftschlauch auszukommen, da das Herbeiführen der Ausgangsstellung der Deckplatte unter Verwendung einer sich entspannenden Feder erfolgt. Vorzugsweise bildet das aus der Grundplatte, dem Schuh, dem Vierkantrohr und einem Teil der Deckplatte gebildete System eine im wesentlichen staubdichte Einheit.In the figure 1 after all a novel doctor blade holding device is shown, which does not require additional elastic dust and dirt seal. This is achieved essentially by the claimed special design and arrangement of the pivoting plane of the doctor blade holding device. The design of the doctor blade holding device according to the invention also makes it possible to make do with only one air hose, since the bringing about the initial position of the cover plate is done using a relaxing spring. Preferably, the system formed from the base plate, the shoe, the square tube and a part of the cover plate forms a substantially dustproof unit.

Die in der Figur 2 dargestellte Schaberklingenhaltevorrichtung weist eine Grundplatte 6 auf, die im wesentlichen U-förmig ausgebildet ist und zwei kurze und eine lange Begrenzungswand aufweist. Im Endbereich einer der kurzen Begrenzungswände ist ein Lagerrohr 5 angeordnet, welches Bestandteil der Grundplatte ist. Das Lagerrohr 5 ist innerhalb eines geschlitzten Vierkantrohres 4 und um einen kleinen Winkel drehbar zu diesem gelagert. Das Vierkantrohr 4 kann in Richtung senkrecht zur Zeichenebene segmentförmig aufgebaut sein, um die Elastizität der Deckplatte 2 möglichst wenig zu beeinträchtigen.The doctor blade holding device shown in Figure 2 has a base plate 6 which is formed substantially U-shaped and has two short and one long boundary wall. In the end of one of the short boundary walls, a bearing tube 5 is arranged, which is part of the base plate. The bearing tube 5 is mounted within a slotted square tube 4 and rotatable about a small angle to this. The square tube 4 may be constructed segment-shaped in the direction perpendicular to the plane to affect the elasticity of the cover plate 2 as little as possible.

Das Vierkantrohr ist mit der Deckplatte 2 fest verbunden, vorzugsweise mittels einer Vielzahl von Schraubverbindungen, die senkrecht zur Zeichenebene hintereinander angeordnet sind, in der Zeichnung aber nicht dargestellt sind. Die Deckplatte 2 besteht vorzugsweise aus Kohlefasermaterial und kann mehrere Kohlefaserschichten aufweisen. Dadurch ist die Deckplatte flexibel und kann sich an die Oberfläche der jeweils zu reinigenden Walze gut anpassen.The square tube is firmly connected to the cover plate 2, preferably by means of a plurality of screw connections, which are arranged perpendicular to the plane one behind the other, but are not shown in the drawing. The cover plate 2 is preferably made of carbon fiber material and may have a plurality of carbon fiber layers. As a result, the cover plate is flexible and can adapt well to the surface of each roller to be cleaned.

Im vorderen Endbereich der Deckplatte 2 sind mittels Schraubverbindungen 3a Fingervorrichtungen 3 an der Deckplatte befestigt, die ebenfalls senkrecht zur Zeichenebene hintereinander angeordnet sind. Zwischen der Deckplatte 2 und den Fingervorrichtungen 3 ist die Schaberklinge 1 eingebracht. Dieses Einbringen der Schaberklinge erfolgt vorzugsweise durch ein Einschieben in Axialrichtung. Da der hintere Endbereich der Schaberklinge mit einer Niete oder Feder 15 versehen ist, kann die Schaberklinge im Betrieb nicht in Richtung der zu reinigenden Walze herausgezogen werden.In the front end region of the cover plate 2 are by means of screw 3a finger devices 3 on the cover plate attached, which are also arranged perpendicular to the plane in a row. Between the cover plate 2 and the finger devices 3, the doctor blade 1 is introduced. This introduction of the scraper blade is preferably carried out by insertion in the axial direction. Since the rear end portion of the doctor blade is provided with a rivet or spring 15, the doctor blade can not be pulled out in the direction of the roller to be cleaned during operation.

Um den jeweils gewünschten Anpressdruck der Schaberklinge an die Oberfläche der zu reinigenden Walze einzustellen, ist im Innenbereich der U-förmigen Grundplatte 6 ein pneumatischer Luftschlauch 14 vorgesehen. Dieser ist an seinem einen Ende mit einem Luftanschluss versehen, durch welchen Luft in den Schlauch gepresst werden kann und auch wieder Luft aus dem Schlauch ausgelassen werden kann. Das andere Ende des Schlauches 14 ist verschlossen. Zwischen dem Schlauch 14 und der langen Begrenzungswand der U-förmigen Grundplatte 6 ist eine Kunststoffeinlage 7 vorgesehen. Diese ist auf die Innenseite der Grundplatte lose eingelegt, aufgeklebt oder angeschraubt und verhindert, dass im Betrieb der Vorrichtung der Schlauch 14 mit einer möglicherweise heißen Begrenzungswand in Berührung kommt.In order to set the particular desired contact pressure of the doctor blade to the surface of the roller to be cleaned, a pneumatic air hose 14 is provided in the interior of the U-shaped base plate 6. This is provided at its one end with an air connection, through which air can be pressed into the hose and also air from the hose can be omitted. The other end of the tube 14 is closed. Between the tube 14 and the long boundary wall of the U-shaped base plate 6, a plastic insert 7 is provided. This is loosely inserted, glued or screwed on the inside of the base plate and prevents the hose 14 comes into contact with a possibly hot boundary wall during operation of the device.

Wird der Luftdruck im Schlauch 14 erhöht, dann dehnt sich dieser aus. Dies bewirkt, dass im Bereich des Schlauches 14 die Deckplatte 2 von der Grundplatte 6 weggedrückt wird. Dies wiederum hat zur Folge, dass die Schaberklinge, die im Bereich des vorderen Endes der Deckplatte an dieser befestigt ist, sich in Richtung des Pfeiles x bewegt bzw. in Richtung x gedrückt wird. Dadurch wird die Schaberklinge an die zu reinigende Walzenoberfläche angelegt und der gewünschte Anpressdruck über ein Druckregelventil eingestellt.If the air pressure in the hose 14 is increased, then this expands. This causes the cover plate 2 is pushed away from the base plate 6 in the region of the tube 14. This in turn has the consequence that the doctor blade, which is fixed in the region of the front end of the cover plate to this, moves in the direction of the arrow x and is pressed in the direction x. As a result, the doctor blade is applied to the roll surface to be cleaned and set the desired contact pressure via a pressure control valve.

Weiterhin weist die in der Figur 2 dargestellte Schaberklingenhaltevorrichtung in der Nähe des Lagerrohres 5 ein erstes Federblech 16 auf, dessen einer Endbereich an der Grundplatte 6 befestigt ist, beispielsweise angeschweißt. Der andere Endbereich des Federbleches 16 stützt sich an der Deckplatte 2 ab, so dass diese zum Abheben der Schabervorrichtung bei einem Klingenwechsel weggedrückt wird. Zu diesem Klingenwechsel muss der Schlauch 14 drucklos sein. Das Federblech 16 dient weiterhin auch als Staubschutz, so dass kein Staub in den Schlitz des geschlitzten Vierkantrohres 4 eindringen kann.Furthermore, the doctor blade holding device shown in Figure 2 in the vicinity of the bearing tube 5, a first spring plate 16, one end of which is fixed to the base plate 6, for example, welded. The other end region of the spring plate 16 is supported on the cover plate 2, so that it is pushed away for lifting the scraper device at a blade change. For this blade change the hose 14 must be depressurized. The spring plate 16 also serves as dust protection, so that no dust can penetrate into the slot of the slotted square tube 4.

In ihrem von der Schaberklinge 1 entfernt gelegenen Endbereich ist an der Deckplatte 2 mittels einer Schraub- oder Nietverbindung 20 ein zweites Federblech 18 befestigt, das den Bereich zwischen dem Ende der Begrenzungswand 9 der Grundplatte 6 und der Deckplatte 2 überbrückt und sich auf der Außenseite der Begrenzungswand 9 der Grundplatte 6 abstützt. Auch dieses Federblech 18 dient als Staubschutz bzw. Schmutzabdichtung.In their remote from the doctor blade 1 end region a second spring plate 18 is secured to the cover plate 2 by means of a screw or rivet connection 20, which bridges the area between the end of the boundary wall 9 of the base plate 6 and the cover plate 2 and on the outside of the Boundary wall 9 of the base plate 6 is supported. This spring plate 18 also serves as dust protection or dirt seal.

Das Federblech 18 gleitet sowohl bei einer Erhöhung als auch bei einer Erniedrigung des Luftdrucks im Schlauch 14 an der Außenfläche der Begrenzungswand 9 entlang.The spring plate 18 slides both in an increase as well as a decrease in the air pressure in the hose 14 on the outer surface of the boundary wall 9 along.

Um die Schaberklingenhaltevorrichtung zusammen mit verschiedenen, am Markt vorhandenen Schaberhaltersystemen verwenden zu können, ist mit dem Federblech 16 und/oder der Grundplatte 6 eine Adapterleiste 17 fest verbunden, beispielsweise unter Verwendung einer Schraube 21. Diese Adapterleiste 17 ist auf der von der Deckplatte 2 abgelegenen Außenseite des Federbleches 16 bzw. der Grundplatte 6 positioniert.In order to use the doctor blade holding device together with various existing on the market Schaberhaltersystemen, with the spring plate 16 and / or the base plate 6, an adapter bar 17 fixedly connected, for example using a screw 21. This adapter bar 17 is on the remote from the cover plate 2 Outside of the spring plate 16 and the base plate 6 is positioned.

In der Figur 2 ist nach alledem eine neuartige Schaberklingenhaltevorrichtung gezeigt, bei der die Schwenkebene der Schaberklingenhaltevorrichtung in spezieller Weise ausgebildet und angeordnet ist. Die in der Figur 2 dargestellte Schaberklingenhaltevorrichtung benötigt nur einen Luftschlauch, da das Herbeiführen der Ausgangsstellung der Deckplatte durch die Kraft des Federbleches 16 erfolgt. Vorzugsweise bildet das aus der Grundplatte 6, dem Federblech 18, einem Teil der Deckplatte 2, dem Vierkantrohr 4 und dem Federblech 16 gebildete System eine im wesentlichen staubdichte Einheit.In the figure 2 after all a novel doctor blade holding device is shown, in which the pivoting plane of the doctor blade holding device is designed and arranged in a special way. The illustrated in Figure 2 Scraper blade holding device requires only one air hose, since the bringing about the starting position of the cover plate is effected by the force of the spring plate 16. Preferably, the system formed from the base plate 6, the spring plate 18, a portion of the cover plate 2, the square tube 4 and the spring plate 16 forms a substantially dustproof unit.
