Description

Die Erfindung betrifft eine Vorrichtung zur Anordnung einer Klinge (Klingenhalterung) an einer Transporteinrichtung einer Warenbahn, insbesondere an einer Walze oder einem Trockenzylinder einer Papiermaschine, bei der die in einer Klingen-Einspanneinrichtung gehaltene Klinge quer zur Laufrichtung einer Warenbahn bringbar ist, wobei die Klingen-Einspanneinrichtung an einem sich quer zur Bahnlaufrichtung erstreckenden Klingentragbalken angeordnet ist, und ein Tragelement mit einem ersten Schwenklager an einem Gestell und mit einem zweiten Schwenklager an dem Klingentragbalken angelenkt ist.The invention relates to a device for arranging a Blade (blade holder) on a transport device a web, in particular on a roller or a Drying cylinder of a paper machine, in which the in a Blade clamping device held across the blade Direction of movement of a web can be brought, the Blade clamping device on one transversely to Blade support bar extending web direction is, and a support member with a first pivot bearing a frame and with a second pivot bearing on the Blade support beam is articulated.

Eine Einsatzmöglichkeit einer solchen Klingenhalterung ist beispielsweise das Beschichten einer Warenbahn, insbesondere einer Papierbahn, mit Streichmasse durch eine Rakel mit der eine möglichst gleichmäßige Schichtdicke erzielt werden soll. Eine andere mögliche Verwendung, ist der Einsatz bei der Herstellung von Kreppapier, bei der eine Warenbahn an einem an einer Transportwalze angeordneten Schaber aufläuft um dadurch die für Kreppapier typische Struktur zu erzeugen. In beiden Einsatzfällen wird die Papierqualität maßgeblich von dem Anpreßdruck der Klinge an die Warenbahn, bzw. an die Transporteinrichtung sowie der Größe des Klingenarbeitswinkels beeinflußt.One possible application of such a blade holder is for example coating a web, especially a paper web, with coating slip by a Squeegee with a layer thickness that is as uniform as possible should be achieved. Another possible use is the use in the production of crepe paper, in the a web of goods on a conveyor roller arranged scraper comes up to thereby the for crepe paper to create typical structure. In both cases the paper quality largely depends on the contact pressure of the Blade on the web or on the transport device as well as the size of the blade working angle.

Zur Erzielung eines guten Arbeitsergebnisses ist es deshalb notwendig, daß die Klinge möglichst exakt in eine vorbestimmte Position gebracht werden kann. Die Klingen verschleißen jedoch, weshalb sie nachdem sie ihre Verschleißgrenze erreicht haben, entweder ausgewechselt oder nachgeschliffen werden müssen. Zur Ausführung dieser Wartungsarbeiten wird die Klinge üblicherweise von ihrer Betriebsposition von der Walze entfernt. Um gleichmäßig qualitativ hochwertige Papierprodukte herstellen zu können, ist es erforderlich, daß die Klinge des Schabers bzw. der anschließend wieder exakt in die zuvor eingenommene Betriebsposition gebracht wird. Ebenso sollten die Klingen auch in ihrer Betriebsposition verstellt werden können, beispielsweise zur Optimierung der Papierqualität oder bei der Umstellung der Papiermaschine auf eine andere Papiersorte. Es hat sich jedoch als schwierig erwiesen vorbestimmte Anordnungen der Klinge mit einer guten Wiederholgenauigkeit einzustellen. Zu diesem Zweck existieren deshalb bereits Klingenhalterungen mit denen dies möglich ist.It is therefore to achieve a good work result necessary that the blade is as precise as possible in one predetermined position can be brought. The blades however, which is why they wear out after their Have reached the wear limit, either replaced or have to be reground. To execute this The blade is usually serviced by her Operating position removed from the roller. To evenly to be able to produce high quality paper products it is necessary that the blade of the scraper or then again exactly in the previously assumed operating position brought. The blades should also be in their operating position can be adjusted, for example to optimize the paper quality or when changing the paper machine to a different type of paper. It however, predetermined blade arrangements have proven difficult with good repeatability. To this end Therefore blade holders already exist with which this is possible.

So ist aus der EP-PS 0 137 837 eine Klingenhalterung vorbekannt bei der die Anordnung einer Klinge einer Rakel durch zwei Drehbewegungen eines Klingentragbalkens um jeweils eine senkrecht zur Transportrichtung verlaufende Schwenk- bzw. Drehachse erreicht wird. Um die Anordnung der Klinge an der Walze zu verändern weist diese Klingenhalterung zwei Stellantriebe mit Gewindetrieben auf, die mittels einer Kupplung und eines Kegelradgetriebes miteinander verbindbar sind. Mit dieser konstruktiv relativ aufwendigen Klingenhalterung können zwar der Anpreßdruck und der Klingenarbeitswinkel jeweils unabhängig voneinander variiert werden. Nicht zufriedenstellend ist jedoch, daß nach einem Auswechseln oder Schleifen der Klinge, wozu der Klingentragbalken von der Walze weggeschwenkt wird, der Klingenarbeitswinkel bei dem Heranführen der Klinge an die Walze wieder verhältnismäfig umständlich "von Hand" neu eingestellt werden muß. Um Qualitätseinbußen zu vermeiden, muß dies sehr genau geschehen. Ein exaktes Einstellen dieses Winkels ist aber zeitaufwendig und verursacht daher Kosten.For example, from EP-PS 0 137 837 a blade holder is known in which the Arrangement of a blade of a squeegee by two rotary movements of one Blade support bar by one perpendicular to the transport direction extending pivot or rotation axis is reached. To the arrangement of the To change the blade on the roller, this blade holder has two Actuators with screw drives, which by means of a clutch and a Bevel gear can be connected to each other. With this constructively relative Elaborate blade holder can be the contact pressure and Blade working angles can be varied independently of each other. Not it is satisfactory, however, that after changing or grinding the Blade, for which the blade support beam is pivoted away from the roller, the Blade working angle when the blade is brought up to the roller again Comparatively cumbersome "by hand" must be reset. Around To avoid loss of quality, this must be done very carefully. A however, exact setting of this angle is time-consuming and therefore causes Costs.

US-A-4 919 756 weist unter anderem die Merkmale 1 bis 1.5 von Anspruch 1 auf. Mit dieser Vorrichtung ist jedoch ein Positionieren der Klinge nach einem Nachschleifen nicht im notwendigen Maße einfach und schnell durchführbar.US-A-4 919 756 has features 1 to 1.5 of claim 1, among others on. With this device, however, is a positioning of the blade after one Regrinding is not quick and easy to carry out.

Es ist Aufgabe der Erfindung, eine Klingenhalterung darzustellen, mit der es entsprechend einem ersten Aspekt der Erfindung möglich ist, nach einem Wegschwenken der Klinge von einer Transporteinrichtung, die Klinge mit guter Wiederholgenauigkeit bezüglich des Klingenarbeitswinkels wieder an der Transporteinrichtung anzuordnen. Dabei soll die Positionierung der Klinge einfacher und schneller als bei aus dem Stand der Technik vorbekannten wieder an der Transporteinrichtung anzuordnen. Dabei soll die Positionierung der Klinge einfacher und schneller als bei aus dem Stand der Technik vorbekannten Klingenhalterungen vorgenommen werden können. Gemäß einem zweiten Aspekt der Erfindung soll es auch möglich sein, den Klingenarbeitswinkel zu verändern ohne daß dabei der Anpreßdruck der Klinge beeeinflußt wird.It is an object of the invention to provide a blade holder with which it is possible according to a first aspect of the invention, according to a Swinging the blade away from a transport device, the blade with good repeatability with regard to the blade working angle to arrange the transport device. The blade should be positioned easier and faster than with previously known from the prior art to be arranged again on the transport device. In doing so the positioning of the blade easier and faster than in previously known from the prior art Blade holders can be made. According to one second aspect of the invention, it should also be possible to To change the blade working angle without the Contact pressure of the blade is affected.

Die Aufgabe wird durch die kennzeichnenden Merkmale des Anspruches 1 gelöst.The task is characterized by the characteristic features of the Claim 1 solved.

Demgemäß ist das Tragelement mit dem zweiten Schwenklager an einem Hebel so schwenkbar angelenkt, daß die Klingenhalterung mit einer mit dem Hebel und dem Tragelement verbundenen Schwenkeinrichtung versehen ist, durch die der Klingentragbalken von einer Betriebsposition in eine einen größeren Abstand zur Walze aufweisenden Wartungsposition geschwenkt werden kann, wobei die Schwenkbewegung durch Veränderung des Abstandes der Anlenkpunkte der Schwenkeinrichtung an dem Hebel und dem Tragelement erfolgt. Desweiteren ist sie mit einer mit dem Gestell und dem Tragelement verbundenen Positioniereinrichtung zur Einstellung eines Klingenarbeitswinkels versehen, wobei die Positionierung der Klinge durch Veränderung des Abstandes der beiden Anlenkpunkte der Positioniereinrichtung an dem Gestell und dem Tragelement erfolgt.Accordingly, the support member with the second pivot bearing hinged on a lever so that the Blade holder with one with the lever and the Support element connected pivot device is provided through which the blade support beam from an operating position at a greater distance from the roller Maintenance position can be pivoted, the Swiveling movement by changing the distance of the Articulation points of the swivel device on the lever and the Carrying element takes place. Furthermore, it is with one with the Frame and the support element connected Positioning device for setting a Blade working angle provided, the positioning the blade by changing the distance between the two Articulation points of the positioning device on the frame and the support element takes place.

Um bei dieser Klingenhalterung den Abstand, der auch Null sein kann, des Klingentragbalkens von der Transporteinrichtung zu vergrößern wird durch die Verschwenkeinrichtung, der Abstand deren Anlenkpunkte an dem Hebel und dem Tragelement um einen bestimmten Betrag vergrößert. Dies kann durch einen mit einem Druckmedium beaufschlagbaren Zylinder der Verschwenkeinrichtung einer bevorzugten Ausführungsform, beispielsweise einem Pneumatikzylinder, erfolgen. Nachdem die Wartungsarbeiten an der Klinge durchgeführt sind, wird der Abstand der beiden Anlenkpunkte wieder auf den ursprünglichen Betrag verringert. Bei dieser Klingenhalterung muß somit zum Wechsel von der Betriebsposition in die Wartungsposition und wieder in die Betriebsposition zurück, lediglich jeweils eine translatorische Bewegung gleicher Länge ausgeführt werden. Aufgrund des nachstehend noch näher erläuterte Zusammenwirkens der Bestandteile der Erfindung weist die Klinge nach diesen beiden Bewegungen wieder den gleichen Klingenarbeitswinkel auf wie zuvor. Eine erfindungsgemäße Klingenhalterung zeichnet sich somit zum einen durch eine einfache Bedienung aus. Zum anderen sind derartige translatorische Bewegungen relativ schnell und auch sehr genau ausführbar, beispielsweise mit dem bereits oben genannten Pneumatikzylinder.At this blade holder the distance, which is also zero can be the blade support beam from the The transport device is enlarged by the Swivel device, the distance of their articulation points the lever and the support element by a certain amount enlarged. This can be done by using a print medium acted upon cylinder of the pivoting device preferred embodiment, for example one Pneumatic cylinder. After the maintenance work are carried out on the blade, the distance of the two articulation points back to the original amount decreased. With this blade holder must therefore Change from the operating position to the maintenance position and back to the operating position, only each a translatory movement of the same length be carried out. Due to the below explained interaction of the components of the invention shows the blade again after these two movements same blade working angle as before. A Blade holder according to the invention is thus characterized one by simple operation. On the other hand such translational movements relatively quickly and also very precisely executable, for example with the one already pneumatic cylinder mentioned above.

In einer bevorzugten Ausführungsform der Erfindung ist die Spitze der Klinge in der Drehachse des ersten Schwenklagers anordenbar. Dies kann zeckmäßigerweise konstruktiv so realisiert sein, daß die Drehachse des Schwenklagers auf einem Radius liegt, auf dem sich die Klinge bei ihrer Bewegung von der Wartungsposition in die Betriebsposition bewegt. Bei einer solchen Ausführungsform ist es dann besonders einfach möglich, den Klingenarbeitswinkel durch verändern des Abstandes der Anlenkpunkte der Positioniereinrichtung an dem Gestell und dem Tragelement zu variieren, ohne daß dadurch der Anpreßdruck der Klinge beeinflußt wird. Dies ist möglich, da bei einer Betätigung der Positioniereinrichtung sich die Klinge nur um ihre Spitze dreht, ohne daß die Anordnung der Klinge bezüglich der Transporteinrichtung in sonstiger Weise verändert wird.In a preferred embodiment of the invention Tip of the blade in the axis of rotation of the first pivot bearing can be arranged. This can be done constructively this way be realized that the axis of rotation of the pivot bearing on a radius on which the blade is at its Movement from the maintenance position to the operating position emotional. In such an embodiment, it is particularly easy possible through the blade working angle change the distance of the articulation points of the Positioning device on the frame and the support element to vary, without thereby the contact pressure of the blade being affected. This is possible because when actuated the positioning device the blade is only about her Tip rotates without changing the blade arrangement the transport device is changed in any other way.

Eine besonders einfache Veränderung des Abstandes der Anlenkpunkte der Positioniereinrichtung läßt sich dadurch erreichen, daß vorzugsweise die Positioniereinrichtung mit einem auf der Verbindungslinie der Anlenkpunkte angeordneten Gewindetrieb versehen ist. A particularly simple change in the distance of the This allows articulation points of the positioning device achieve that preferably the positioning device with one on the connecting line of the articulation points arranged screw drive is provided.

Um eine besonders einfache Bedienung zu erreichen, weist die Erfindung in einer zweckmäßigen Ausbildung eine Steuerung auf. Die erfindungsgemäße Klingenhalterung ist dadurch mit entsprechenden Steuerungssignalen, beispielsweise von einem Bedienungspult aus, ferngesteuert in die Wartungs- und Betriebsposition überführbar. Ebenso ist damit eine ferngesteuerte Einstellung des Klingenarbeitswinkels erzielbar.In order to achieve a particularly simple operation, points the invention in a practical training Control on. The blade holder according to the invention is with corresponding control signals, for example, from a control panel, remotely controlled can be transferred to the maintenance and operating position. As well is a remote controlled setting of the Blade working angle achievable.

Es wird desweiteren bevorzugt, daß bei einer Ausführung der Erfindung der jeweils aktuelle Klingenarbeitswinkel durch eine Sensorik detektierbar und als entsprechendes elektrisches Signal ausgebbar ist. Führt man diese dem jeweils aktuellen Klingenarbeitswinkel entsprechenden Signale einer Regeleinrichtung zu, kann ein exakter Abgleich zwischen einer Soll- und Ist-Anordnung des Klingentragbalkens erzielt werden.It is further preferred that when the Invention of the current blade working angle a sensor system is detectable and as a corresponding one electrical signal can be output. If you lead this to the corresponding to the current blade working angle Signals to a control device can be an exact Comparison between a target and actual arrangement of the Blade support beam can be achieved.

Fig.2).The support element 3, starting from a foot part 8, two approximately perpendicularly aligned support arms 9, 10 on. Between the support element 3 and the frame 5 is located as a positioning device 14 Screw drive 15. This is from a not shown Electric motor driven and is between a pivot point 16 on the frame 5 and a pivot point 17 on the first Support arm 9 of the support element 3 along an (imaginary) Connecting line 18 of the two articulation points 16, 17 arranged. The screw drive 15 is in each case the two pivot points 16, 17 rotatably attached. Through a the first pivot bearing 20 is the support element 3 with its second support arm 10 also pivotable on the frame 5 attached (see especially Fig. 2).

Wie desweiteren in Fig.1 zu erkennen ist, ist der Klingentragbalken 2, der starr mit dem Hebel 4 verbunden ist, in einem zweiten Lager drehbar und axial verschiebbar (hier nicht dargestellt) im Fußteil 8 des Tragelementes 3 gelagert. Zwischen einem Anlenkpunkt 22 im Bereich des anderen Endes des Hebels 4 und einem weiteren Anlenkpunkt 23 an dem ersten Tragarm 9 des Tragelementes 3 befindet sich eine Schwenkeinrichtung 24. Diese ist mit einem Pneumatikzylinder 25 versehen, dessen Wirkrichtung entlang der Verbindungslinie 26 der beiden Anlenkpunkte 22, 23 der Schwenkeinrichtung 24 verläuft. Die Verbindungslinie 26 weist dabei einen größeren Abstand zu dem Schwenklager 21 auf als die Verbindungslinie 18. Ebenso wie der Gewindetrieb 15 ist auch der Pneumatikzylinder 25 jeweils um seine beiden Anlenkpunkte 22, 23 drehbar befestigt.As can also be seen in FIG. 1, the Blade support beam 2, which is rigidly connected to the lever 4 is rotatable and axially displaceable in a second bearing (not shown here) in the foot part 8 of the support element 3 stored. Between a pivot point 22 in the area of other end of the lever 4 and another articulation point 23 is located on the first support arm 9 of the support element 3 a swivel device 24. This is with a Pneumatic cylinder 25 provided, the direction of action along the connecting line 26 of the two pivot points 22, 23 of the Swivel device 24 extends. The connecting line 26 has a greater distance from the pivot bearing 21 on as the connecting line 18. Just like the The screw drive 15 is also the pneumatic cylinder 25 in each case attached rotatably about its two articulation points 22, 23.

Das Gestell 5, in dem auch die nicht dargestellte Drehachse der Walze 1 gelagert ist, weist an seinem unteren Ende eine mit einem Gewindebolzen 27 verstellbare Lasche 28 auf. An der Lasche 28 des Gestells 5 befindet sich der Anlenkpunkt 16 der Positioniereinrichtung 14 und das erste Schwenklager 20 des Tragelementes 3. Durch Drehen des Gewindebolzens 27 kann der Abstand des Anlenkpunktes 16 und des ersten Schwenklagers 20 von der Umfangslinie der Walze 1 entlang einer Verschiebeachse verändert werden. Unter "Abstand" ist in diesem Zusammenhang jeweils die Projektion der in den Figuren tatsächlich räumlich verlaufenden Abstandslinie in die Zeichenebenen der Fig.1 - 3 zu verstehen.The frame 5, in which the axis of rotation, not shown the roller 1 is mounted, has at its lower end with a threaded bolt 27 adjustable tab 28. On the tab 28 of the frame 5 is the articulation point 16 of the positioning device 14 and the first pivot bearing 20 of the support element 3. By turning the threaded bolt 27 can the distance between the pivot point 16 and the first Swivel bearing 20 along the circumferential line of the roller 1 a displacement axis can be changed. Under "distance" is in this context, the projection of the in the Figures actually spaced in to understand the drawing levels of FIGS. 1-3.

Der Klingentragbalken 2, bei dem es sich im dargestellten Ausführungsbeispiel um einen Tragbalken eines Schabers 30 handelt, ist zusammen mit dem Tragelement 3 und dem Hebel 4 in dem zweiten Schwenklager 21 gelagert. Er kann um die Achse des zweiten Schwenklagers 21 Relativbewegungen gegenüber dem Tragelement 3 ausführen. Gegenüber dem Hebel 4 ist der Klingentragbalken 2 drehfest angeordnet.The blade support beam 2, which is shown in the Embodiment around a support beam of a scraper 30 is together with the support element 3 and the lever 4th stored in the second pivot bearing 21. He can do that Axis of the second pivot bearing 21 relative movements run against the support element 3. Opposite the lever 4, the blade support beam 2 is arranged in a rotationally fixed manner.

Der Anpreßdruck des auf dem Klingentragbalken 2 befindlichen Schabers 30 kann mit einer nicht dargestellten, an sich aus dem Stand der Technik vorbekannten, Klingen-Einspanneinrichtung variiert werden. Dies geschieht dadurch, daß der Schaber 30 entlang seiner gesamten Länge (senkrecht zur Zeichenebene) durchgebogen wird und somit eine Biegekraft in Richtung auf die Walze 1 entsteht. The contact pressure of the on the blade support beam 2 located scraper 30 can not with a illustrated, per se from the prior art previously known, blade clamping device can be varied. This happens because the scraper 30 along its entire length (perpendicular to the drawing plane) and thus a bending force in the direction of the roller 1 arises.

Vor dem erstmaligen Einsatz der Klingenhalterung befindet sie sich in einer Wartungsposition wie es in Fig.2 dargestellt ist. Dabei ist die Achse des ersten Schwenklagers 20 mit Hilfe des Gewindebolzens 27 so justiert worden, daß sie sich, wie Fig.2 zeigt, unmittelbar über der Umfangslinie der Walze 1 befindet. Nachdem der Schaber 30 auf dem Klingentragbalken 2 befestigt und auf ihm eine einen vorbestimmter Anpreßdruck bewirkende Biegekraft aufgebracht ist, wird er durch Betätigung der Schwenkeinrichtung 24 in einer Betriebsposition an der Walze 1 angeordnet. Die scharfe Kante, bzw. in den Darstellungen der Figuren die Klingenspitze, des Schabers 30 fluchtet dabei mit der Drehachse des zweiten Schwenklagers 21. Die zweite, nicht dargestellte an der anderen Stirnseite der Walze 1 angeordnete erfindungsgemäße Klingenhalterung, ist stets in der gleichen Weise ausgerichtet wie die dargestellte Klingenhalterung. Um den Klingentragbalken 2 zu verschwenken führen die beiden Klingenhalterungen auch stets synchron gleiche Bewegungen aus.Before using the blade holder for the first time they are in a maintenance position as shown in Fig. 2 is shown. Here is the axis of the first Swivel bearing 20 using the threaded bolt 27 so been adjusted so that it, as Fig.2 shows, immediately located above the circumference of the roller 1. After the Scraper 30 attached to the blade support beam 2 and on it causes a predetermined contact pressure Bending force is applied, it is activated by pressing the Swivel device 24 in an operating position on the Roller 1 arranged. The sharp edge, or in the Representations of the figures the blade tip, the scraper 30 is aligned with the axis of rotation of the second Swivel bearing 21. The second, not shown on the other end of the roller 1 arranged according to the invention Blade holder is always in the same way aligned like the blade holder shown. To the Swivel blade support beam 2 lead the two Blade holders also always synchronously same movements out.

Zur Einstellung des Klingenarbeitswinkels, d.h. des Winkels den eine Tangente an der Walze 1 durch die Klingenspitze zusammen mit Klinge eingeschließt, kann das Gestell 3 gemeinsam mit dem Klingentragbalken 2 um die Klingenspitze geschwenkt werden. Dazu kommt die Positioniereinrichtung 14 zum Einsatz. Soll beispielsweise ausgehend von der in Fig.1 gezeigten Anordnung der Schaber 30 mit einem Klingenarbeitswinkel von Fig.3 versehen werden, so wird der Gewindetrieb 15 der Positioniereinrichtung 14 in der Weise betätigt, daß sich der Abstand der beiden Anlenkpunkte 16, 17 um einen dem neuen Klingenarbeitswinkels entsprechenden Betrag vergrößert. Dadurch dreht sich das Tragelement 3 in Gegenuhrzeigerrichtung um das erste Schwenklager 20. Da hierbei der Abstand der beiden Anlenkpunkte 22, 23 gleich bleibt, folgt der Hebel dieser Bewegung. Dies bedingt insgesamt eine Drehbewegung des Klingentragbalkens 2, ebenfalls im Gegenuhrzeigersinn, nur um das erste Schwenklager 20 zur Folge.To adjust the blade working angle, i.e. of the angle the one tangent to the roller 1 through the blade tip included with the blade, the frame 3 together with the blade support beam 2 around the blade tip be pivoted. In addition, there is the positioning device 14 for use. For example, if the shown arrangement of the scraper 30 with a Blade working angle of Fig.3 are provided, so the Screw drive 15 of the positioning device 14 in the manner actuated that the distance between the two pivot points 16, 17 by one corresponding to the new blade working angle Amount increased. This rotates the support member 3 in Counterclockwise direction around the first pivot bearing 20. Da here the distance between the two articulation points 22, 23 is the same remains, the lever follows this movement. This requires a total of a rotary movement of the blade support beam 2, also counterclockwise, just around the first Swivel bearing 20 result.

Wie oben bereits beschrieben, fluchtet die Klingenspitze mit der Achse des ersten Schwenklagers 20. Dies hat zur Folge, daß sich der Klingentragbalken 2 um die Klingenspitze dreht, wodurch sich nach Beendigung der Bewegung der neue Klingenarbeitswinkel einstellt. Es besteht dabei ein funktionaler Zusammenhang zwischen dem jeweiligen Abstand der Anlenkpunkte und dem dadurch bedingten Klingenarbeitswinkel. Durch obige Erläuterungen wird deutlich, daß der Klingenarbeitswinkel unabhängig vom Anpreßdruck stufenlos eingestellt werden kann. Dies kann sogar während des Betriebes der Papiermaschine vorgenommen werden, beispielsweise um einen Verschleiß der Klingenspitze des Schabers 30 zu kompensieren. Somit können einerseits für bestimmte Papiersorten als optimal gefundene Klingenarbeitswinkel jederzeit auf einfache Weise reproduzierbar eingestellt und beibehalten werden. Andererseits ist es auf ebenso einfache Art und Weise möglich ohne Veränderung des Anpreßdrucks den Klingenarbeitswinkels selbst während des Betriebes zu optimieren.As already described above, the blade tip is aligned with the axis of the first pivot bearing 20. This has to Consequence that the blade support beam 2 around The tip of the blade rotates, which after the end of the Movement sets the new blade working angle. It there is a functional connection between the respective distance of the articulation points and the thereby conditional blade working angle. Through the above explanations it becomes clear that the blade working angle regardless of Contact pressure can be adjusted continuously. This can even made during the operation of the paper machine be, for example, to wear the To compensate for the blade tip of the scraper 30. So you can on the one hand for certain types of paper found to be optimal Blade working angle at any time in a simple way reproducibly set and maintained. On the other hand, it is just as simple possible without changing the contact pressure Blade working angle even during operation optimize.

Da sich der Schaber 30 auf der imaginären Verbindungslinie der Achsen der beiden Schwenklager 20, 21 befindet, entstehen beim Einsatz keine Momente um die Achse des zweiten Schwenklagers 21. Dadurch können trotz der dynamischen Belastung des Schabers 30 Torsionsschwingungen vermieden werden. Ein weiterer Vorteil resultiert daraus, daß die Klingenspitze mit der Achse des ersten Schwenklagers 20 fluchtet. Durch diese Anordnung ist es möglich, die an der Klinge wirkenden dynamischen Belastungen ohne Entstehung von Momenten in das robust ausgeführte Gestell 5 der nicht dargestellten Stuhlung der Papiermaschine abzuleiten. Because the scraper 30 is on the imaginary connecting line the axes of the two pivot bearings 20, 21 is located, there are no moments around the axis of the second pivot bearing 21. This allows despite the dynamic load on the scraper 30 torsional vibrations be avoided. Another advantage results from that the blade tip with the axis of the first Swivel bearing 20 is aligned. With this arrangement it is possible, the dynamic acting on the blade Loads without creating moments in the robust executed frame 5 of the chair, not shown Derive paper machine.

Wie bekannt ist, verschleißen derartige Schaber während ihres Einsatzes. Nachdem nun der Verschleiß dieses Schabers 30 eine zuläßige Toleranz überschritten hat, wird die Papierherstellung unterbrochen und der Pneumatikzylinder 25 der Schwenkeinrichtung 24 umgekehrt druckbeaufschlagt. Aufgrund der translatorischen Bewegung der Zylinderstange 29 des Pneumatikzylinders 25 vergrößert sich der Abstand der beiden Anlenkpunkte 22, 23 um einen bestimmten Betrag. Der Hebel 4 führt deshalb eine Schwenkbewegung im Uhrzeigersinn um die Achse des zweiten Schwenklagers 21 aus. Der drehfest mit dem Hebel 4 verbundene Klingentragbalken 2 wiederum dreht sich somit ebenfalls im Uhrzeigersinn um das zweite Schwenklager 21. Dadurch vergrößert sich, wie in Fig.2 dargestellt, der Abstand des Schabers 30 von der Walze 1.As is known, such scrapers wear out during of their use. Now that this scraper is worn 30 has exceeded a permissible tolerance, the Paper production interrupted and the pneumatic cylinder 25 the swiveling device 24 conversely pressurized. Due to the translational movement of the cylinder rod 29 of the pneumatic cylinder 25, the distance increases of the two pivot points 22, 23 by a certain amount. The lever 4 therefore performs a pivoting movement in the Clockwise around the axis of the second pivot bearing 21 out. The rotatably connected to the lever 4 Blade support beam 2 in turn also rotates in Clockwise around the second pivot bearing 21. This increases, as shown in Fig.2, the distance of the Scraper 30 from the roller 1.

Der Schaber 30 ist in dieser Wartungsposition der Klingenhalterung seitlich zugänglich und kann gegebenenfalls gegen einen anderen ausgetauscht werden. Falls es aufgrund des Verschleißzustandes noch möglich ist wird der Schaber 30 jedoch vorzugsweise nachgeschliffen. Die Breite des Schabers 30 verringert sich jedoch dadurch. Damit die Klingenspitze trotz unterschiedlicher Breiten des Schabers 30 stets in die Achse des ersten Schwenklagers 20 gebracht werden kann, stützt sich der Schaber 30 mit seinem der Klingenspitze gegenüberliegenden Ende an einer nicht dargestellten, verstellbaren Anschlagsfläche ab. Mit der Anschlagleiste lassen sich unterschiedliche Breiten des Schabers 30 kompensieren. Nachdem sich der Schaber 30 auf dem Klingentragbalken 2 wieder in der vorgesehenen Anordnung befindet, wird durch ursprüngliche Druckbeaufschlagung des Pneumatikzylinders 25 der Abstand der beiden Anlenkpunkte 22, 23 wieder auf den ursprünglichen Betrag verringert. Der Hebel 4 und der Klingentragbalken 2 drehen sich dadurch im Gegenuhrzeigersinn um das zweite Schwenklager 21 entlang des gleichen Weges zurück in ihre ursprüngliche Anordnung, der Betriebsposition. Dadurch ist der Klingentragbalken an der Walze 1 mit dem gleichen Klingenarbeitswinkel und Anpreßdruck wie zuvor angeordnet.The scraper 30 is in this maintenance position Blade holder accessible from the side and can if necessary, be exchanged for another. If it is still possible due to the state of wear however, the scraper 30 is preferably reground. However, the width of the scraper 30 is reduced. So that the blade tip despite different widths of the Scraper 30 always in the axis of the first pivot bearing 20th can be brought, the scraper 30 is supported with his at one end not opposite the blade tip illustrated, adjustable stop surface. With the Stop bar can be of different widths Compensate scraper 30. After the scraper 30 is on the blade support beam 2 again in the intended Arrangement is made by original Pressurizing the pneumatic cylinder 25 the distance of the two articulation points 22, 23 again on the original amount decreased. The lever 4 and the Blade support beam 2 thereby rotate in Counterclockwise around the second pivot bearing 21 along the same way back to their original arrangement, the operating position. As a result, the blade support beam is on the roller 1 with the same blade working angle and Contact pressure arranged as before.

In anderen in den Figuren nicht dargestellten Ausführungsformen der Erfindung kann auch vorgesehen sein, daß die Steifigkeit der jeweils an einer der Stirnseiten der Walze angeordneten erfindungsgemäßen Klingenhalterungen durch mechanische Querverbindungen, beispielsweise einer Querstrebe, vergrößert wird. Ebenso ist es möglich manuell betätigte Trapezgewindespindeln anstelle der Elektroantriebe der Gewindetriebe vorzusehen.In others not shown in the figures Embodiments of the invention can also be provided that the rigidity of each on one of the end faces of the roller arranged blade holders according to the invention by mechanical cross connections, for example one Cross strut, is enlarged. It is also possible manually actuated trapezoidal lead screws instead of Provide electric drives for the screw drives.
