Description

Die gegenständliche Erfindung betrifft eine Einrichtung zur lösbaren Befestigung eines in einer Anlage zur Papiererzeugung befindlichen Halters für eine Schaberklinge, wobei die Schaberklinge, welche einer in dieser Anlage befindlichen Trag- bzw. Führungswalze für das Siebband, für das Filzband oder für das Papierband zugeordnet ist, mittels einer Stelleinrichtung in ihrer Lage gegenüber der Trag- bzw. Führungswalze einstellbar ist und wobei weiters der Halter für die Schaberklinge an einem Träger für den Halter mittels einer Führung zumindest angenähert in Achsrichtung der Trag- bzw. Führungswalze verschiebbar sowie am Träger in der Betriebsstellung feststellbar ist.The subject invention relates to a device for releasably securing a holder for a doctor blade located in a plant for paper production, wherein the doctor blade, which is assigned to a support or guide roller for the screen belt, for the felt belt or for the paper tape located in this plant, by means of an adjusting device in its position relative to the support or guide roller is adjustable and further wherein the holder for the doctor blade on a support for the holder by means of a guide at least approximately in the axial direction of the support or guide roller displaceable and detectable on the carrier in the operating position is.

In Anlagen zur Papiererzeugung befindet sich ein Siebband, welches über Trag- bzw. Führungwalzen längs der Anlage bewegt wird und auf welches der Papierbrei aufgebracht wird. In der Bewegungsrichtung des Siebbandes wird aus dem Papierbrei die in diesem enthaltene Flüssigkeit abgesaugt und wird das hierdurch erzeugte Papierband mittels durch das Siebband hindurchgesaugte Luft getrocknet. In weiterer Folge befindet sich in dieser Anlage ein Filzband, auf welchem das Papierband weiter getrocknet wird. Sowohl das Siebband als auch das Filzband werden über Trag- und Führungswalzen bewegt. In weiterer Folge wird das Papierband unmittelbar über die Trag- und Führungswalzen bewegt.In plants for paper production is a sieve belt, which is moved over support or guide rollers along the system and on which the pulp is applied. In the direction of movement of the screen belt, the liquid contained in this is sucked from the pulp and the paper belt produced thereby is dried by sucked through the wire belt air. Subsequently, in this system is a felt belt on which the paper tape is further dried. Both the wire belt and the felt belt are moved over support and guide rollers. Subsequently, the paper tape is moved directly over the support and guide rollers.

Aufgrund der aus dem Papierbrei abgesaugten Flüssigkeit und aufgrund der Trocknungsvorgänge gelangen auf die Trag- bzw. Führungswalzen aus dem Papierbrei bzw. aus dem Papierband abgeführte Bestandteile, insbesondere Zellulosefasern, durch welche die Trag- bzw. Führungswalzen verschmutzt werden. Da durch diese Verschmutzungen die Funktion der Trag- bzw. Führungswalzen beeinträchtigt wird, besteht das Erfordernis, diese einer andauernden Reinigung zu unterziehen. Hierfür ist den Trag- und Führungswalzen jeweils eine Schaberklinge zugeordnet, welche an die betreffende Trag- und Führungswalze zur Anlage gebracht wird, wodurch von dieser Walze auf derselben befindliche Verschmutzungen abgeschabt werden.Due to the extracted from the pulp liquid and due to the drying operations get on the support or guide rollers from the pulp or from the paper tape discharged components, in particular cellulose fibers through which the support or guide rollers are dirty. Since the function of the support or guide rollers is impaired by these contaminants, there is a need to subject them to a continuous cleaning. For this purpose, the carrier and guide rollers each associated with a scraper blade, which is brought to the relevant support and guide roller to the plant, which are scraped off from this roller on the same dirt.

Dabei besteht das Erfordernis, die Schaberklinge so anzuordnen, dass sie an die betreffende Walze mit einem vorgegebenen Druck anliegt. Hierfür ist der Halter für die Schaberklinge mit einer Einrichtung zur Verstellung der Winkellage der Schaberklinge gegenüber der betreffenden Walze ausgebildet. Weiters muss der Halter für die Schaberklinge, welcher sich an einem Träger für diesen Halter befindet, an diesem Halter lösbar befestigt sein. Da der Halter für die Schaberklinge mit der Einrichtung zur Einstellung der Winkellage der Schaberklinge oftmals ausgetauscht werden muss, um diese Bauteile reinigen zu können, besteht weiters das Erfordernis, die Befestigung des Halters für die Schaberklinge am Träger für den Halter so auszubilden, dass sie in möglichst einfacher Weise hergestellt oder gelöst werden kann.There is a need to arrange the doctor blade so that it rests against the relevant roller with a predetermined pressure. For this purpose, the holder for the doctor blade with a device for adjusting the angular position of the doctor blade formed opposite the respective roller. Furthermore, the holder for the doctor blade, which is located on a support for this holder, must be releasably secured to this holder. Since the holder for the doctor blade must be replaced with the means for adjusting the angular position of the doctor blade often to clean these components, there is also the need to attach the holder of the holder for the doctor blade on the support for the holder so that they as simple as possible can be made or solved.

Aus dem Stand der Technik ist es bekannt, den Halter für die Schaberklinge und den Träger für diesen Halter mit einander zugeordneten Führungsleisten auszubilden, welchen eine Befestigungsschraube zugeordnet ist, wobei die Führungsleisten durch die Befestigungsschraube miteinander verklemmt werden.From the prior art it is known to form the holder for the doctor blade and the carrier for this holder with associated guide rails, which is associated with a fastening screw, wherein the guide rails are clamped together by the fastening screw.

Der gegenständlichen Erfindung liegt die Aufgabe zugrunde, eine Verklemmung zu schaffen, welche wesentlich einfacher betätigt werden kann, wobei eine ebenso wirkungsvolle Verklemmung erzielt wird. Dies wird erfindungsgemäß dadurch erzielt, dass zwischen dem Halter für die Schaberklinge und dem Träger für den Halter ein Druckschlauch vorgesehen ist, durch welchen der Halter für die Schaberklinge mit dem Träger für den Halter verklemmbar ist.The subject invention has for its object to provide a deadlock, which can be operated much easier, with an equally effective deadlock is achieved. This is inventively achieved in that between the holder for the doctor blade and the carrier for the holder, a pressure hose is provided, through which the holder for the doctor blade with the carrier for the holder is clamped.

Vorzugsweise sind der Halter und der Träger mit einander zugeordneten, sich in Achsrichtung der Trag- und Führungswalze erstreckenden Leisten ausgebildet, welche vom Halter und vom Träger schräg abragen, wodurch sie durch Aufblähen des Druckschlauches miteinander verklemmt werden. Dabei können der Halter für die Schaberklinge und der Träger für den Halter als angenähert parallel zueinander ausgerichtete Platten ausgebildet sein, welche mit in Achsrichtung verlaufenden und von den Platten schräg abragenden Führungsleisten ausgebildet sind, welche einander zugeordnet sind, und kann der Druckschlauch, welcher zwischen den beiden Platten angeordnet ist, sich zwischen den beiden Paaren der einander zugeordneten Führungsleisten befinden und parallel zu diesen ausgerichtet sein.Preferably, the holder and the carrier are associated with each other, formed in the axial direction of the support and guide roller extending strips which project obliquely from the holder and the carrier, whereby they are jammed together by inflating the pressure hose. In this case, the holder for the doctor blade and the support for the holder may be formed as approximately parallel to each other aligned plates which are formed with extending in the axial direction and obliquely projecting from the plates guide rails, which are associated with each other, and the pressure hose, which between the two plates is arranged, located between the two pairs of mutually associated guide rails and be aligned parallel to these.

Sobald ein gereinigter Halter mit einer Schaberleiste mittels der Führungsleisten in Achsrichtung der Walzen in die Betriebsstellung geschoben worden ist, wird der Druckschlauch aufgebläht, wodurch der Halter für die Schaberklinge mit dem Träger für den Halter verklemmt wird. Sobald der Halter mit einer Schaberklinge entfernt werden soll, wird der im Druckschlauch bestehende Druck abgesenkt, wodurch der Halter gegenüber dem Träger verschoben und in weiterer Folge von diesem gelöst werden kann. Hierauf kann in den Träger ein gereinigter Halter mit einer Schaberklinge eingeschoben und mit diesem durch den Druckschlauch verklemmt werden.Once a cleaned holder has been pushed with a scraper strip by means of the guide rails in the axial direction of the rollers in the operating position, the pressure hose is inflated, whereby the holder for the doctor blade is jammed with the carrier for the holder. As soon as the holder is to be removed with a doctor blade, the existing pressure in the pressure hose is lowered, whereby the holder is moved relative to the carrier and subsequently released from this can be. Then it can be inserted into the carrier a cleaned holder with a doctor blade and jammed with this through the pressure hose.

In Fig. 1 ist eine Trag- und Führungswalze 1 dargestellt, welche sich in einer Anlage zur Papiererzeugung unterhalb des Siebbandes, des Filzbandes oder des Papierbandes befindet. Der Walze 1 ist eine Schaberklinge 2 zugeordnet, welche an die Oberfläche der Walze 1 zur Anlage gebracht werden kann, wobei sie der Drehrichtung der Walze 1 entgegengesetzt ausgerichtet ist. Durch die Schaberklinge 2 werden auf der Oberfläche der Walze 1 befindliche Verschmutzungen, welche durch die Entwässerung des am Siebband befindlichen Papierbreies bzw. durch die Trocknung des Papierbandes verursacht werden, entfernt.In Fig. 1, a support and guide roller 1 is shown, which is located in a plant for paper production below the wire belt, the felt belt or the paper tape. The roller 1 is associated with a scraper blade 2, which can be brought to the surface of the roller 1 for conditioning, being aligned opposite to the direction of rotation of the roller 1. By the doctor blade 2 are on the surface of the roller 1 located contaminants, which are caused by the dewatering of the screen belt located Papierbreies or by the drying of the paper tape removed.

Die Schaberklinge 2 ist an einem Halter 3 für die Schaberklinge 2 befestigt. Der Halter 3 ist dabei mit einer Stelleinrichtung 4 ausgebildet, welche dazu dient, die Winkellage der Schaberklinge 2 gegenüber dem Halter 3 bzw. gegenüber der Oberfläche der Walze 1 einstellen zu können. Der Halter 3 für die Schaberklinge 2 ist an einem Träger 6 für den Halter 3 lösbar befestigt. Zwischen dem Halter 3 und dem Träger 6 befindet sich weiters eine Einrichtung 5, durch welche der Halter 3 am Träger 6 in einfacher Weise befestigbar bzw. von diesem lösbar ist.
Der Träger 6 ist an einer Welle 7 befestigt, welche sich in Achsrichtung der Walze 1 erstreckt und welche mittels eines Spannschlosses 8 in eine Schwenklage einstellbar und ist dieser feststellbar ist.The doctor blade 2 is attached to a holder 3 for the doctor blade 2. The holder 3 is formed with an adjusting device 4, which serves to adjust the angular position of the doctor blade 2 relative to the holder 3 and against the surface of the roller 1 can. The holder 3 for the doctor blade 2 is releasably secured to a support 6 for the holder 3. Between the holder 3 and the carrier 6 is further a device 5, by which the holder 3 on the carrier 6 in a simple manner attachable or detachable from this.
The carrier 6 is fixed to a shaft 7, which extends in the axial direction of the roller 1 and which by means of a turnbuckle 8 adjustable in a pivot position and this is detected.

Wie dies aus Fig.2 ersichtlich ist, besteht die Stelleinrichtung 4 aus einem Gehäuse, welches einen unteren Gehäuseteil 41 und einen oberen Gehäuseteil 42 aufweist, wobei der obere Gehäuseteil 42 mittels eines Gelenkes 43 am unteren Gehäuseteil 41 verschwenkbar gelagert ist. Weiters liegt das freie Ende 44 des oberen Gehäuseteiles 42 an die Oberseite der Schaberklinge 2 an. Innerhalb der Gehäuseeteile 41 und 42 befinden sich zwei voneinander im Abstand angeordnete, aufblähbare Schläuche 45 und 46, welche in Achsrichtung der Walze 1 ausgerichtet sind und durch welche der obere Gehäuseteil 42 gegenüber dem unteren Gehäuseteil 41 so verschwenkbar ist, dass die Schaberklinge 2 mit einem einstellbaren Druck an die Oberfläche der Walze 1 anliegt.As can be seen from Fig.2, the adjusting device 4 consists of a housing which has a lower housing part 41 and an upper housing part 42, wherein the upper housing part 42 is pivotably mounted by means of a hinge 43 on the lower housing part 41. Furthermore, the free end 44 of the upper housing part 42 abuts the upper side of the doctor blade 2. Within the housing parts 41st and 42 are two mutually spaced, inflatable tubes 45 and 46, which are aligned in the axial direction of the roller 1 and through which the upper housing part 42 relative to the lower housing part 41 is pivotable so that the doctor blade 2 with an adjustable pressure to the Surface of the roller 1 is applied.

Wie dies aus Fig.2a ersichtlich ist, ist der Halter 3 für die Schaberklinge 2 mit zwei schräg nach unten ragenden und in Achsrichtung der Walze 1 ausgerichteten Leisten 31 und 32 ausgebildet, welchen am Träger 6 befindliche und schräg nach oben abragende Leisten 61 und 62 zugeordnet sind. Diese Leistenpaare 31, 32 und 61, 62 bilden Führungen, mittels welcher der Halter 3 gegenüber dem Träger 6 in Achsrichtung der Walze 1 verschiebbar ist, wie dies in Fig. 1 durch einem Doppelpfeil angedeutet ist. Hierdurch kann der Halter 3 mit der Schaberklinge 2 vom Träger 6 für den Halter 3 abgezogen werden, um gereinigt zu werden und kann auf den Träger 6 ein gereinigter Halter 3 mit einer Schaberklinge 2 aufgeschoben werden.As can be seen from Figure 2a, the holder 3 for the doctor blade 2 with two obliquely downwardly projecting and aligned in the axial direction of the roller 1 bars 31 and 32 is formed, which are located on the support 6 and obliquely upwardly projecting strips 61 and 62nd assigned. These strip pairs 31, 32 and 61, 62 form guides by means of which the holder 3 relative to the carrier 6 in the axial direction of the roller 1 is displaceable, as indicated in Fig. 1 by a double arrow. In this way, the holder 3 can be removed with the doctor blade 2 from the carrier 6 for the holder 3 to be cleaned and can be pushed onto the carrier 6, a cleaned holder 3 with a doctor blade 2.

Die Einrichtung 5 zur Befestigung des Halters 3 für die Schaberklinge 2 am Träger 6 ist durch einen Druckschlauch 51 gebildet, welcher sich zwischen dem Halter 3 und dem Träger 6 bzw. zwischen den einander zugeordneten Leisten 31, 61 und 32, 62 befindet. Sobald der Druckschlauch 51 aufgebläht wird, wird der Halter 3 vom Träger 6 abgehoben und werden die von diesen schräg abragenden Leisten 31, 61 und 32, 62 ineinander verkeilt, wodurch der Halter 3 mit dem Träger 6 verklemmt wird. Sobald der Druck im Druckschlauch 51 vermindert wird, wird diese Verklemmung aufgehoben, wodurch der Halter 3 gegenüber dem Träger 6 verschoben und von diesem gelöst werden kann.The device 5 for fixing the holder 3 for the doctor blade 2 on the carrier 6 is formed by a pressure hose 51 which is located between the holder 3 and the carrier 6 and between the associated strips 31, 61 and 32, 62. As soon as the pressure hose 51 is inflated, the holder 3 is lifted off the carrier 6 and the strips 31, 61 and 32, 62 projecting obliquely from one another are wedged into one another, whereby the holder 3 is jammed with the carrier 6. Once the pressure in the pressure hose 51 is reduced, this deadlock is released, whereby the holder 3 can be moved relative to the carrier 6 and released from it.

Hierdurch ist eine sehr einfach betätigbare und dessen ungeachtet sehr wirksame Befestigung des Halters 3 für eine Schaberklinge 2 am Träger 6 für den Halter 3 geschaffen, wodurch der Halter 3 mit der Schaberklinge 2 in einfacher Weise vom Träger 6 entfernt und durch einen gereinigten Halter 3 ersetzt werden kann.As a result, a very easy operable and its nonetheless very effective attachment of the holder 3 for a doctor blade 2 on the support 6 created for the holder 3, whereby the holder 3 with the doctor blade 2 in a simple manner removed from the carrier 6 and replaced by a cleaned holder 3 can be.
