Schaberklingenhaitevorrichtung Schaberklingenhaitevorrichtung
Die Erfindung betrifft eine Schaberklingenhaltevorrich- tung 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 the context of paper production or in the steel industry. It is used to hold a scraper blade for the purpose of even contact with a rotating roller or roller in order to clean its surface during operation. Such a roller can have a width of several meters. The scraper blade provided for cleaning such a roller must lie against the roller as evenly as possible at a predetermined angle over the entire length of the roller. To achieve this, the doctor blade is generally applied to the roller with a relatively large pressure.
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 Scha- berklinge 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. Der 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 Be- trieb auftretenden hohen Temperaturen hitzebeständigeFrom WO 93/21380 a scraper blade holding device is already known, which has two holding elements. A first part of the doctor blade is inserted between the holding elements mentioned. The second part of the doctor blade leads away from the holding elements. One of these holding elements is a plate that consists of a multiplicity of fiber layers. The number and orientation of these fiber layers depends on the desired working conditions of the doctor blade. To adjust and change the pressure with which the doctor blade rests against the roller, two pneumatic hoses are provided, one of which - from the doctor's point of view - is located in front of and behind a pivot point. The The fulcrum is provided in the central area of the base plate. The desired contact pressure of the scraper blade on the roller can be adjusted by suitably inflating or emptying the hoses. 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, its implementation is complex. In addition, because of the high temperatures that occur during operation, it is heat-resistant

Aus der EP 1 186 703 A2 ist eine Schaberanordnung be- kannt, 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 Schaberan- Ordnung ohne eine Dichtung verwendet, dann ist ein häufiges Reinigen der Vorrichtung notwendig. Dies ist aber wegen der engen Einbausituation ungemein schwierig.A scraper arrangement is known from EP 1 186 703 A2, which has a blade carrier and a scraper blade. The blade carrier is arranged on a blade holder so as to be pivotable about an axis, with at least one pressure element being arranged between the blade carrier and the blade holder, which is independent of the pressure, i.e. H. maintains its basic shape. A pressure element is preferably arranged on both sides of the axis. With this arrangement, too, the axis is located in the central region of the base plate or blade holder. By means of the pressure elements mentioned, which are hoses, the desired contact pressure of the doctor blade against the roller can be set and the doctor blade can also be lifted off the roller by generating a suitable counterpressure. If this known scraper arrangement is used without a seal, then frequent cleaning of the device is necessary. However, this is extremely difficult due to the narrow installation situation.
Der Erfindung liegt die Aufgabe zugrunde, eine Schaber- klingenhaltevorrichtung anzugeben, bei der die vorstehend genannten Nachteile nicht auftreten. Diese Aufgabe wird durch eine Schaberklingenhaltevorrich- tung mit den im Anspruch 1 angegebenen Merkmalen gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den abhängigen Ansprüchen.The invention is based on the object of specifying a doctor blade holding device in which the disadvantages mentioned above do not occur. This object is achieved by a doctor blade holding device with the features specified in claim 1. Advantageous refinements and developments of the invention result 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 vorteil- hafter 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 a separate dirt or dust seal can be omitted due to the claimed design and positioning of the axle. The pivot bearing advantageously also serves as a dirt or dust seal. Consequently, it is not necessary to use complex and expensive rubber or Viton seals.
Vorzugsweise ist die Deckplatte mit einem geschlitzten Vierkantrohr verbunden, innerhalb dessen das in einemPreferably, the cover plate is connected to a slotted square tube, within which the one
Endbereich der Grundplatte vorgesehene Lagerrohr drehbar ist .End region of the base plate provided bearing tube is rotatable.
Mittels der im Anspruch 3 angegebenen Merkmale wird er- reicht, 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.It is achieved by means of the features specified in claim 3 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 remove a large number of screws in order to be able to remove the cover plate.
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 Deckplat- te beim Einsetzen und Herausziehen verbessert. Weiterhin wird dadurch auch eine verbesserte Staub- und Schmutzabdichtung erreicht.If the base plate is contacted with a shoe provided for receiving the cover plate, as specified in claims 4 and 5, then the guidance of the cover plate during insertion and removal is improved. Furthermore, an improved dust and dirt seal is also 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. 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.The features of claim 7 ensure that components located in the inner region of the base plate, in particular the pneumatic hose, are protected from contact with the boundary walls of the base plate, which in some cases become very hot during operation. The features of claim 8 ensure that the scraper blade holding device manages with only one hose. If the hose is filled with air, depending on the air pressure this leads to a stronger pressing of the doctor blade against the roller to be cleaned. At the same time, a spring is pulled apart or tensioned. If the air is released from the hose, the spring that contracts or relaxes causes the scraper blade to be lifted off the roller to be cleaned. A second hose, as is provided in the previously known arrangements, is not necessary. The spring return mentioned is necessary, for example, for changing the doctor blade.
Vorzugsweise bilden ein Teil der Deckplatte, das Vierkantrohr, die Grundplatte und der Schuh eine im wesentlichen staubdichte Einheit.Preferably, part of the cover plate, the square tube, the base plate and the shoe form an essentially dust-proof 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 properties of the invention result from its exemplary explanation with reference to the figures. These show sketches of a doctor blade holding device according to two exemplary embodiments of the invention.
Die in der Figur 1 dargestellte Schaberklingenhaltevorrichtung weist eine Grundplatte 6 auf, die im wesentlichen ü-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 scraper blade holding device shown in FIG. 1 has a base plate 6 which is essentially U-shaped and has two short and one long boundary wall. A bearing tube 5, which is part of the base plate, is arranged in the end region of one of the short boundary walls. The bearing tube 5 is mounted within a slotted square tube 4 and rotatable by a small angle to it.
Das Vierkantrohr ist mit einer Deckplatte 2 fest verbun- den, 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 Kohlefa- sermaterial 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 a cover plate 2, preferably by means of a plurality of screw connections which are arranged one behind the other perpendicular to the plane of the drawing, but are not shown in the drawing. The cover plate 2 is preferably made of carbon fiber material and can have several carbon fiber layers. As a result, the cover plate is flexible and can adapt well to the surface of the 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 Deckplat- te 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 Schaber- klinge 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 3a, which are also arranged one behind the other perpendicular to the plane of the drawing. The scraper blade 1 is inserted between the cover plate 2 and the finger devices 3. This introduction of the doctor blade is preferably carried out by inserting it in the axial direction. Since the rear end region of the doctor blade is provided with a rivet or spring 15, the doctor blade cannot 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 β 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 verhin- dert, dass im Betrieb der Vorrichtung der Schlauch 14 mit einer möglicherweise heißen Begrenzungswand in Berührung kommt .In order to set the respectively desired contact pressure of the doctor blade against the surface of the roller to be cleaned, a pneumatic air hose 14 is provided in the inner region of the U-shaped base plate β. This is provided at one end with an air connection through which air can be pressed into the hose and air can also be let out of the hose. The other end of the hose 14 is closed. A plastic insert 7 is provided between the hose 14 and the long boundary wall of the U-shaped base plate 6. This is loosely inserted, glued or screwed onto the inside of the base plate and prevents the hose 14 from coming 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 be¬ wegt bzw. in Richtung x gedrückt wird. Dadurch wird die Schaberklinge an die zu reinigende Walzenoberfläche angelegt und der gewünschte Anpressdruck über ein Druckregel- ventil eingestellt.If the air pressure in the hose 14 is increased, it expands. This causes the cover plate 2 to be pushed away from the base plate 6 in the region of the hose 14. This in turn has the consequence that the scraper blade, which is in the area of the front end of the cover plate this is fixed, is moved in the direction of arrow x ¬ be or is pressed in the direction x. As a result, the doctor blade is placed on the roller surface to be cleaned and the desired contact pressure is set using 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 ver- schiebbar 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 gege- ben, 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 inner region of the U-shaped base plate 6. One end of which is connected to the long boundary wall of the base plate 6. The other end of the spring 8 is fastened to a shoe 10 which is provided for receiving the rear end region of the cover plate 2. The shoe forms a guide rail in a direction perpendicular to the plane of the drawing, within which the cover plate is mounted so as to be displaceable 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 can be pivoted together with the cover plate relative to the base plate. This pivotability is provided by the fact that in the boundary wall 9 of the base plate there are provided elongated holes 13 through which rivets 12 connected to the sliding surface 11 of the shoe 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 .If 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. In der Figur 1 ist nach alledem eine neuartige Schaber- klingenhaltevorrichtung gezeigt, welche keine zusätzliche elastische Staub- und Schmutzabdichtung benötigt. Dies wird im wesentlichen durch die beanspruchte spezielle Ausbildung und Anordnung der Schwenkebene der Schaber- klingenhaltevorrichtung erreicht. Die Ausgestaltung der Schaberklingenhaltevorrichtung gemäß der Erfindung ermöglicht es weiterhin, mit nur einem Luftschlauch auszukommen, da das Herbeiführen der Ausgangsstellung der Deck- platte 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.If the doctor blade 1 is to be lifted off the roller surface again, for example to change the blade, then the air is let out of the hose 14. The spring 8, which then contracts again, moves the shoe 10 back in the drawing plane to the left into its starting position, so that the cover plate 2 is also pivoted back into its starting position. After all of this, FIG. 1 shows a new type of scraper blade holding device which does not require an additional elastic dust and dirt seal. This is essentially achieved by the claimed special design and arrangement of the swivel plane of the doctor blade holding device. The design of the doctor blade holding device according to the invention also makes it possible to get by with only one air hose, since the starting position of the cover plate is brought about using a relaxing spring. The system formed from the base plate, the shoe, the square tube and a part of the cover plate preferably forms an essentially dust-tight 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 scraper blade holding device shown in FIG. 2 has a base plate 6 which is essentially U-shaped and has two short and one long boundary wall. A bearing tube 5, which is part of the base plate, is arranged in the end region of one of the short boundary walls. The bearing tube 5 is mounted within a slotted square tube 4 and rotatable by a small angle to it. The square tube 4 can be segment-shaped in the direction perpendicular to the plane of the drawing in order to impair 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 ange- ordnet 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 an- passen.The square tube is firmly connected to the cover plate 2, preferably by means of a large number of screw connections which are arranged one behind the other perpendicular to the plane of the drawing, but are not shown in the drawing. The cover plate 2 is preferably made of carbon fiber material and can have several carbon fiber layers. As a result, the cover plate is flexible and can adapt well to the surface of the roller to be cleaned.
Im vorderen Endbereich der Deckplatte 2 sind mittels Schraubverbindungen 3a Fingervorrichtungen 3 an der Deck- platte 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 er- folgt 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 attached to the cover by means of screw connections 3a. plate attached, which are also arranged one behind the other perpendicular to the plane of the drawing. The scraper blade 1 is inserted between the cover plate 2 and the finger devices 3. The scraper blade is preferably introduced by being pushed in in the axial direction. Since the rear end region of the doctor blade is provided with a rivet or spring 15, the doctor blade cannot 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 desired contact pressure of the doctor blade against the surface of the roller to be cleaned, a pneumatic air hose 14 is provided in the inner region of the U-shaped base plate 6. This is provided at one end with an air connection through which air can be pressed into the hose and air can also be let out of the hose. The other end of the hose 14 is closed. A plastic insert 7 is provided between the hose 14 and the long boundary wall of the U-shaped base plate 6. This is loosely inserted, glued or screwed onto the inside of the base plate and prevents the hose 14 from coming 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 ange- legt und der gewünschte Anpressdruck über ein Druckregelventil eingestellt. Weiterhin weist die in der Figur 2 dargestellte Schaber- klingenhaltevorrichtung 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 uss der Schlauch 14 drucklos sein. Das Federblech 16 dient weiterhin auch als Staub- schütz, so dass kein Staub in den Schlitz des geschlitzten Vierkantrohres 4 eindringen kann.If the air pressure in the hose 14 is increased, it expands. This causes the cover plate 2 to be pushed away from the base plate 6 in the region of the hose 14. This in turn has the consequence that the doctor blade, which is fastened to the cover plate in the region of the front end thereof, moves in the direction of the arrow x or is pressed in the direction x. As a result, the doctor blade is placed on the roller surface to be cleaned and the desired contact pressure is set using a pressure control valve. Furthermore, the scraper blade holding device shown in FIG. 2 has a first spring plate 16 in the vicinity of the bearing tube 5, one end region of which is attached to the base plate 6, for example welded on. The other end region of the spring plate 16 is supported on the cover plate 2, so that it is pressed away to lift off the scraper device when the blade is changed. The hose 14 must be depressurized for this blade change. The spring plate 16 also serves as a dust protector, so that no dust can penetrate 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 its end area located away from the scraper blade 1, a second spring plate 18 is fastened 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 is located on the outside of the Boundary wall 9 of the base plate 6 supports. 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 along the outer surface of the boundary wall 9 both with an increase and with a decrease in the air pressure in the hose 14.
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 be able to use the doctor blade holding device together with various doctor holder systems available on the market, an adapter strip 17 is firmly connected to the spring plate 16 and / or the base plate 6, for example using a screw 21. This adapter strip 17 is on the one remote from the cover plate 2 Positioned outside of the spring plate 16 or the base plate 6.
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 darge- stellte 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. After all of this, FIG. 2 shows a new type of doctor blade holding device in which the pivoting plane of the doctor blade holding device is designed and arranged in a special way. The shown in Figure 2 The scraper blade holding device only requires an air hose, since the starting position of the cover plate is brought about by the force of the spring plate 16. The system formed from the base plate 6, the spring plate 18, a part of the cover plate 2, the square tube 4 and the spring plate 16 preferably forms an essentially dust-proof unit.
