Description

Die gegenständliche Erfindung betrifft eine Einrichtung zur Reinigung einer Walze in einer Anlage zur Papiererzeugung mit einer der Oberfläche der Walze zugeordneten Schaberklinge, welche mittels zweier parallel zur Achse der Walze ausgerichteter Lagerzapfen gegenüber der Walze verschwenkbar gelagert ist, wobei an mindestens einem der beiden Lagerzapfen ein Stellhebel befestigt ist, durch welchen die Schaberklinge verschwenkbar ist.
Bekannte derartige Einrichtungen dienen dazu, an den Oberflächen von Walzen in Anlagen zur Papiererzeugung befindliche Verunreinigungen, insbesondere in Form von Fasern, zu entfernen, um hierdurch eine den Erfordernissen entsprechende Funktion der Walzen zu gewährleisten.The subject invention relates to a device for cleaning a roller in a plant for paper production with a surface of the roller associated scraper blade, which is pivotally mounted relative to the roller by means of two aligned parallel to the axis of the roller bearing journal, wherein at least one of the two journals an adjusting lever is fastened, by which the doctor blade is pivotable.
Known devices of this kind are used to remove impurities, particularly in the form of fibers, located on the surfaces of rolls in papermaking plants, in order to ensure a function of the rolls corresponding to the requirements.

Dabei ist die Schaberklinge an einem sich über die Länge der Walze erstreckenden Schaberbalken befestigt. Der Schaberbalken ist an seinen beiden Enden mit Lagerzapfen ausgebildet, mittels welcher er in Lagern verdrehbar ist. Weiters sind die Lager quer zur Drehachse der Walze verstellbar.The scraper blade is at one extending over the length of the roller Scraper attached. The scraper is at its two ends with trunnions formed, by means of which it is rotatable in bearings. Furthermore, they are Bearing transversely to the axis of rotation of the roller adjustable.

Um den Schaberbalken verschwenken zu können, ist weiters auf jeder Seite der Walze ein Stellhebel vorgesehen, welcher mit dem zugeordneten Lagerzapfen verbunden ist. Durch eine Verschwenkung des Stellhebels sind die Lagerzapfen verdrehbar, wodurch der Schaberbalken mit der Schaberklinge gegenüber der Oberfläche der Walze verstellbar ist. Eine Verstellung der Schaberklinge gegenüber der Oberfläche der Walze ist einerseits dann erforderlich, soferne die Schaberklinge ausgetauscht werden soll, und ist andererseits dann erforderlich, soferne der Anstellwinkel der Schaberklinge geändert werden soll.In order to pivot the scraper, is on each side of the Roller a lever provided, which is connected to the associated journal is. By pivoting the control lever are the journals rotatable, causing the doctor blade with the doctor blade against the surface the roller is adjustable. An adjustment of the doctor blade against the Surface of the roller is then required on the one hand, provided the doctor blade exchanged should be, and on the other hand then required, provided the angle of attack the doctor blade should be changed.

Es ist bekannt, den Stellhebel mit dem jeweiligen Lagerzapfen dadurch zu verbinden, dass der Stellhebel mittels Schrauben mit dem Lagerzapfen verklemmt wird (vgl. US-A-1 786 587). Nach einem Lösen der Schrauben ist der Lagerzapfen gegenüber dem Stellhebel verdrehbar, wodurch die Winkellage der Schaberklinge verstellt werden kann. Wenngleich somit mittels einer derartigen kraftschlüssigen Verbindung des Stellhebels mit dem Lagerzapfen in einfacher Weise eine Verstellung des Schaberbalkens erzielbar ist, ist diese Verbindung deshalb nachteilig, da aufgrund der im Betrieb auftretenden Drehmomente, welche auf diese Verbindung zur Wirkung kommen, eine unerwünschte Verstellung der Schaberklinge gegenüber den Lagerzapfen erfolgen kann.It is known to connect the adjusting lever with the respective bearing pin thereby that the adjusting lever is clamped by means of screws with the bearing journal (see US-A-1 786 587). After loosening the screws, the bearing pin is opposite the adjusting lever rotatable, whereby the angular position of the doctor blade can be adjusted. Although thus by means of such a frictional connection of the actuating lever with the bearing pin in a simple way an adjustment of the scraper bar is achievable, this compound is therefore disadvantageous because of the in operation occurring torques, which come to this connection to the effect an undesired adjustment of the scraper blade against the journals done can.

Um diesen Nachteil zu vermeiden, ist es weiters bekannt, die Stellhebel und die Lagerzapfen mit einander zugeordnete Nuten auszubilden, in welche eine Paßfeder eingesetzt ist. Durch eine derartige formschlüssige Verbindung sind die Stellhebel und die Lagerzapfen miteinander in einer vorgegebenen Drehlage verbunden, welche sich während des Betriebes nicht verändern kann. Der Nachteil dieser Verbindung besteht jedoch darin, dass keine Verstellung der Drehlage der Drehzapfen gegenüber den Stellhebeln möglich ist, um hierdurch eine Voreinstellung der Schwenklage des Schaberbalkens zu bewirken.To avoid this disadvantage, it is also known, the levers and the Form bearing journal with mutually associated grooves, in which a feather key is used. By such a positive connection are the levers and the trunnions connected together in a predetermined rotational position, which can not change during operation. The disadvantage of this connection However, it is that no adjustment of the rotational position of the pivot opposite the levers is possible to thereby preset the pivotal position of the To effect scraper bar.

Der gegenständlichen Erfindung liegt somit die Aufgabe zugrunde, in einer derartigen Einrichtung die Verbindung des Stellhebels mit dem zugeordneten Lagerzapfen zwar formschlüssig auszubilden, wodurch eine unerwünschte Verstellung ausgeschlossen wird, wobei jedoch dessen ungeachtet die Möglichkeit bestehen soll, die Drehlage des Lagerzapfens gegenüber dem Stellhebel den technischen Erfordernissen entsprechend verstellen zu können. Dies wird erfindungsgemäß dadurch erzielt, dass der Lagerzapfen und der Stellhebel mit einander zugeordneten Rastelementen ausgebildet sind, mittels welcher der Lagerzapfen und der Stellhebel in unterschiedlichen Lagen zueinander miteinander formschlüssig verbindbar sind.The subject invention thus has the object, in such Establish the connection of the actuating lever with the associated bearing pin Although form-fitting form, whereby an undesirable adjustment excluded However, it should nevertheless be possible to have the Rotary position of the journal relative to the lever to the technical requirements to adjust accordingly. This is achieved according to the invention that the bearing pin and the adjusting lever with associated latching elements are formed, by means of which the bearing pin and the lever in different Layers are mutually positively connected with each other.

Vorzugsweise ist der Stellhebel mit einer zweiteiligen Klemmhülse ausgebildet, welche beiden Teile miteinander starr verbindbar sind, wobei mindestens einer der beiden Teile an seiner Innenseite mit einer Profilierung ausgebildet ist. Dabei ist insbesondere der am Stellhebel lösbar befestigbare Hülsenteil an seiner Innenseite mit einer Profilierung ausgebildet. Weiters sind insbesondere die beiden Hülsenteile miteinander mittels Schraubbolzen starr verbindbar. Die Profilierungen sind vorzugsweise durch parallel zur Achse des Lagerzapfens ausgerichtete Rippen bzw. Nuten, insbesondere durch Zahnungen, gebildet.
Nach einer bevorzugten Ausführungsform ist der Lagerzapfen mit einem zusätzlichen Bauteil ausgebildet, welcher an seiner Oberfläche mit einer Profilierung, insbesondere mit einer Zahnung, ausgebildet. Dabei kann sich der zusätzliche Bauteil im Bereich einer Abflachung oder einer Ausnehmung des Lagerzapfens befinden.
Der Gegenstand der Erfindung ist nachstehend anhand eines in der Zeichnung dargestellten Ausführungsbeispieles näher erläutert. Es zeigen:

Preferably, the adjusting lever is formed with a two-part clamping sleeve, which two parts are rigidly connected to each other, wherein at least one of the two parts is formed on its inside with a profiling. In this case, in particular, the sleeve part releasably fastenable on the adjusting lever is formed on its inside with a profiling. Furthermore, in particular the two sleeve parts are rigidly connected to each other by means of bolts. The profilings are preferably formed by parallel to the axis of the journal aligned ribs or grooves, in particular by serrations.
According to a preferred embodiment, the bearing journal is formed with an additional component, which on its surface with a profiling, in particular with a toothing formed. In this case, the additional component may be in the region of a flattening or a recess of the journal.

In Fig.1 ist eine Walze 1 in einer Anlage zur Papiererzeugung dargestellt, welcher eine Schaberklinge 2 zugeordnet ist. Die Schaberklinge 2 befindet sich auf einem Schaberbalken 3, welcher sich parallel zur Achse der Walze 1 über deren gesamte Länge erstreckt. An seinen beiden Stirnenden ist der Schaberbalken 3 mit Lagerzapfen 4 ausgebildet, welche sich in Lagern 5 befinden. An den Lagerzapfen 4 sind Stellhebel 6 befestigt, welche über Stellantriebe 7 um die Achse der Lagerzapfen 4 verschwenkbar sind, wobei hierdurch eine Verdrehung der Lagerzapfen 4 bzw. eine Verschwenkung des Schaberbalkens 3 und der Schaberklinge 2 gegenüber der Oberfläche der Walze 1 erfolgt. Da zudem die Lager 5 quer zur Walze 1 verstellbar sind, ist hierdurch auch der Anstellwinkel der Schaberklinge 2 gegenüber der Walze 1 einstellbar.In Fig.1 a roll 1 is shown in a plant for paper production, which a doctor blade 2 is assigned. The scraper blade 2 is located on a Scraper bar 3, which is parallel to the axis of the roller 1 over the entire Length extends. At its two front ends of the scraper bar 3 with journals 4 formed, which are located in bearings 5. At the bearing pin 4 are Adjusting lever 6 attached, which about actuators 7 about the axis of the bearing pin. 4 are pivotable, whereby thereby a rotation of the bearing pin 4 and a Pivoting of the scraper bar 3 and the scraper blade 2 with respect to the surface the roller 1 takes place. In addition, since the bearings 5 are adjustable transversely to the roller 1, This is also the angle of attack of the doctor blade 2 relative to the roller. 1 adjustable.

In Fig.2 sind die linke Stirnseite der Walze 1, die Schaberklinge 2, der Schaberbalken 3, der linke Lagerzapfen 4, das zugeordnete Lager 5, der linke Stellhebel 6, die linke Stelleinrichtung 7 sowie ein Flansch 41, an welchen der Schaberbalken 3 angeschraubt ist, dargestellt. Das Lager 5 ist in Richtung des Doppelpfeiles C gegenüber der Walze 1 verstellbar. Die Stelleinrichtung 7 ist durch eine Stellschraube oder durch einen Stellzylinder gebildet. Durch eine Betätigung der Stelleinrichtung 7 wird der Stellhebel 6 verschwenkt bzw. wird der Lagerzapfen 4 verdreht. Hierdurch wird der Schaberbalken 3 mit der Schaberklinge 2 gegenüber der Walze 1 verschwenkt. Durch eine Verstellung des Lagers 5 kann die Schaberklinge 2 an die Walze 1 zur Anlage gebracht werden.
Es wird hiezu auch auf die Darstellung der Fig.3 verwiesen, in welcher unterschiedliche Stellwinkel der Schaberklinge 2 angedeutet sind.2, the left end face of the roller 1, the doctor blade 2, the scraper bar 3, the left bearing pin 4, the associated bearing 5, the left adjusting lever 6, the left adjusting device 7 and a flange 41, to which the scraper bar 3 is screwed is presented, layed out. The bearing 5 is adjustable in the direction of the double arrow C relative to the roller 1. The adjusting device 7 is formed by a set screw or by an actuating cylinder. By actuating the adjusting device 7, the adjusting lever 6 is pivoted or the bearing pin 4 is rotated. As a result, the doctor blade 3 is pivoted with the doctor blade 2 relative to the roller 1. By adjusting the bearing 5, the doctor blade 2 can be brought to the roller 1 to the plant.
Reference is also made to the illustration of Figure 3, in which different angles of the doctor blade 2 are indicated.

Wie dies in Fig.4 dargestellt ist, ist der Stellhebel 6 mit einer Klemmhülse 8 ausgebildet, welche aus zwei Teilen 81 und 82 besteht, welche mittels zweier Schrauben 84 miteinander verbindbar sind. Die Klemmhülse 8 dient dazu, den Stellhebel 6 mit dem zugeordneten Lagerzapfen 4 formschlüssig zu verbinden, um hierdurch eine starre Verbindung des Stellhebels 6 mit dem Scherbalken 3 zu gewährleisten.
Diese Verbindung besteht darin, dass der Teil 82 an seiner Innenseite mit einer parallel zur Drehachse des Lagerzapfens 4 ausgebildeten Zahnung 83 ausgebildet ist, welcher am Lagerzapfen 4 eine gegengleiche Zahnung 43 zugeordnet ist. Dabei erstreckt sich die Zahnung 43 gegenüber der Zahnung 83 etwa um den doppelten Winkel.As shown in Figure 4, the adjusting lever 6 is formed with a clamping sleeve 8, which consists of two parts 81 and 82 which are connected to each other by means of two screws 84. The clamping sleeve 8 serves to positively connect the adjusting lever 6 with the associated bearing pin 4, thereby ensuring a rigid connection of the actuating lever 6 with the shear bar 3.
This connection consists in that the part 82 is formed on its inner side with a toothing 83 formed parallel to the axis of rotation of the bearing journal 4, which toothing 43 is assigned a counter toothing 43 on the bearing journal 4. In this case, the teeth 43 opposite the teeth 83 extends approximately twice the angle.

Wie dies aus den Fig.5 und 6 ersichtlich ist, ist die Zahnung 43 des Zapfens 4 dadurch hergestellt, dass der Zapfen 4 mit einer Abflachung 40 ausgebildet ist, welcher ein Auflageteil 42 zugeordnet ist, welcher mit der Zahnung 43 ausgebildet ist. Diese Ausbildung ist insoferne besonders vorteilhaft, da eine Abflachung auf dem Lagerzapfen 4 in sehr einfacher Weise herstellbar ist. Auf diese Abflachung braucht nur der im Querschnitt als Kreisabschnitt ausgebildete Auflageteil 42 aufgebracht zu werden, welcher an seiner Außenfläche mit der Zahnung 43 ausgebildet ist.As can be seen from Figures 5 and 6, the toothing 43 of the pin 4 is characterized manufactured, that the pin 4 is formed with a flattening 40, which a support member 42 is associated, which is formed with the toothing 43. These Training is particularly advantageous insofar as a flattening on the journal 4 can be produced in a very simple manner. This flattening only needs the formed in cross section as a circular section support member 42 applied to which is formed on its outer surface with the teeth 43.

Um die Schaberklinge 2 austauschen zu können, wird der Schaberbalken 3 verschwenkt. Um eine Einstellung der Schwenklage der Schaberklinge 2 gegenüber der Walze 1 vornehmen zu können, werden die beiden Hülsenteile 81 und 82 voneinander gelöst, wodurch die Zahnung 83 von der Zahnung 43 gelöst werden kann. Hierauf kann der Lagerzapfen 4 verdreht werden, wodurch die Winkellage der Schaberklinge 2 gegenüber der Walze 1 verändert wird. Hierauf werden die beiden Hülsenteile 81 und 82 mittels der Schrauben 84 miteinander verschraubt, wodurch die Zahnungen 83 und 43 miteinander verrastet werden und eine formschlüssige Verbindung erzielt wird. Somit kann durch ein Lösen der Schrauben 84 und eine Verdrehung der Lagerzapfen 4 in einfacher Weise eine Änderung des Anstellwinkels der Schaberklinge 2 gegenüber der Walze 1 bewirkt werden.In order to replace the doctor blade 2, the doctor blade 3 is pivoted. To an adjustment of the pivotal position of the doctor blade 2 against the To make roller 1, the two sleeve parts 81 and 82 from each other dissolved, whereby the toothing 83 can be released from the teeth 43. hereupon can the bearing pin 4 are rotated, whereby the angular position of the doctor blade 2 is changed relative to the roller 1. Then the two sleeve parts 81 and 82 screwed together by means of screws 84, whereby the Serrations 83 and 43 are locked together and a positive connection is achieved. Thus, by loosening the screws 84 and a rotation the bearing pin 4 in a simple manner, a change in the angle of the Scraper blade 2 relative to the roller 1 can be effected.

Wie dies aus Fig.5 ersichtlich ist, kann hierdurch eine Einstellung der Verbindung zwischen dem Lagerzapfen 4 und dem Stellhebel 6 in einem Winkelbereich von z.B. 50° bewirkt werden.As can be seen from Fig.5, thereby adjusting the connection between the trunnion 4 and the control lever 6 in an angular range of e.g. 50 ° can be effected.
