Abstract

The assembly (10) to position and/or transfer a roller (14) at a papermaking machine has at least one lifting system (20) at the machine frame (18), linked to the machine frame (18) at one side and the bearing pedestal (22) of the roller (14) at the other side. The lifting system (20) is fitted with a sliding movement across the load-bearing direction, and the roller axis, at the machine frame (18) and bearing pedestal (22). Sliding couplings (24,26) are at the machine frame (18) and bearing pedestal (22), as linkage points for the lifting system (20). The lifting system (20) has at least one lifting cylinder (20'). An upper linkage point (28), between the lifting system (20) and the machine frame (18), is set to reduce the horizontal movement of the roller (14) to a min. through distortion of the machine frame (18) when under a load. The lifting system (20) and/or the bearing pedestal (22) at the roller (14) are additionally linked at the sides to the machine frame (18) by at least one setting cylinder (32). For a blanket change, the lifting system (20) and the setting cylinder are controlled and set so that the roller (14) only has a vertical movement, and the setting cylinder (32) is not charged for a blanket change. The lifting system (20) and the setting cylinder (32) are in a combination for control so that the roller (14) can be given a movement away from the vertical, and the setting cylinder (32) can move the roller (14) horizontally independently of the lifting system (20). The setting cylinder (32) gives the roller (14) a side movement, when it has been lifted into the upper position and locked in place. A lifting system (20) is for each bearing pedestal (22) at both ends of the roller (14), and a side movement can be given to both ends of the roller (14). The lifting system (20) is brought to the upper roller (14) of a web press station with two press rollers (14,16). A mechanical lock is at the lifting system (20) and the setting cylinder (32), to secure the weight of the lifted and/or deflected roller (14) for safety in the event of a cable break.

Description

Die Erfindung betrifft eine Vorrichtung zur Positionierung und/oder Verlagerung einer in einer Papiermaschine eingesetzten Walze, mit wenigstens einer an einem Maschinengestell abgestützten Hubeinrichtung, die einerseits an dem Maschinengestell und andererseits an einem der Walze zugeordneten Lagerbock angelenkt ist.The invention relates to a device for positioning and / or displacement a roller used in a paper machine, with at least a lifting device supported on a machine frame, on the one hand on the machine frame and on the other hand on one of the rollers Bearing block is articulated.

Bei einer aus der WO 98/06896 bekannten Vorrichtung der eingangs genannten Art ist die Hubeinrichtung starr an der Stuhlung angelenkt. Das beim Anheben der Walze in einen Kantileverträger eingeleitete Moment führt zu einer Verdrehung der führerseitigen Stuhlung. Durch die starre Anlenkung an der Stühlung wird die Walze nach dem Verlassen der Zentrierung zur Gegenwalze seitlich ausgelenkt. Demzufolge kann beim Absenken der Walze die ursprüngliche Position nicht mehr erreicht werden.In a device known from WO 98/06896 of the aforementioned Art is the lifting device rigidly hinged to the chair. The moment initiated when lifting the roller in a cantilever leads to a twisting of the driver's chair. Through the rigid The roller is articulated on the frame after leaving the centering laterally deflected to the counter roller. As a result, when lowering the roller's original position can no longer be reached.

Ziel der Erfindung ist es, eine Vorrichtung der eingangs genannten Art zu schaffen, die unabhängig von unter Last auftretenden Verformungen der Stuhlung bzw. des Maschinengestells und unabhängig von geometrischen Vorgaben ein genaues Positionieren der Walze ermöglicht.The aim of the invention is to provide a device of the type mentioned create, regardless of the deformations occurring under load Chair or the machine frame and regardless of geometric Precise positioning of the roller is made possible.

Diese Aufgabe wird nach der Erfindung dadurch gelöst daß, die Hubeinrichtung sowohl an dem Maschinengestell als auch an dem der Walze zugeordneten Lagerbock allgemein quer zur Lastrichtung und Walzenachse verschiebbar befestigt ist.This object is achieved according to the invention in that the lifting device both on the machine frame and on that assigned to the roller Bearing bracket generally transverse to the load direction and roller axis is slidably attached.

Aufgrund dieser Ausbildung kann die Krafteinleitung optimal zum Walzenschwerpunkt eingestellt werden. Damit ist unabhängig von unter Last auftretenden Verformungen des Maschinengestells und unabhängig von geometrischen Vorgaben stets ein äußerst genaues Positionieren der Walze möglich.Due to this training, the application of force can optimally to the center of gravity can be set. It is independent of under load occurring deformations of the machine frame and regardless of geometrical specifications always an extremely precise positioning of the roller possible.

Bei einer zweckmäßigen praktischen Ausführungsform der erfindungsgemäßen Vorrichtung ist die Hubeinrichtung an schieberartigen Koppelelementen angelenkt, die an dem Maschinengestell bzw. dem Lagerbock geführt sind.In an expedient practical embodiment of the invention The device is the lifting device on slide-like coupling elements articulated, which led to the machine frame or the bearing block are.

Die Hubeinrichtung umfaßt vorzugsweise wenigstens einen Hubzylinder.The lifting device preferably comprises at least one lifting cylinder.

Bei einer bevorzugten praktischen Ausführungsform ist ein zwischen der Hubeinrichtung und dem Maschinengestell vorgesehener oberer Anlenkpunkt so gewählt, daß die sich aufgrund einer lastbedingten Verformung des Maschinengestells ergebende horizontale Verlagerung der Walze auf ein Minimum reduziert ist.In a preferred practical embodiment, a between the Lifting device and the upper articulation point provided on the machine frame chosen so that the due to a load-related deformation resulting horizontal displacement of the roller on the machine frame a minimum is reduced.

Die Hubeinrichtung und/oder der der Walze zugeordnete Lagerbock kann zusätzlich auch seitlich an dem Maschinengestell angelenkt sein. So kann beispielsweise die Hubeinrichtung im Bereich ihres an dem Lagerbock angelenkten Endes seitlich an dem Maschinengestell angelenkt sein. The lifting device and / or the bearing block assigned to the roller can also be articulated laterally on the machine frame. So can for example, the lifting device in the area of its articulated on the bearing block End be articulated laterally on the machine frame.

Bei einer zweckmäßigen praktischen Ausführungsform erfolgt die seitliche Anlenkung über wenigstens ein Stellglied, vorzugsweise wenigstens einen Stellzylinder, um die seitliche Auslenkung der Walze unabhängig von geometrischen Vorgaben wie Länge und Befestigungspunkten der Anlenkung sowie Hub der Hubeinrichtung einstellen zu können.In a practical practical embodiment, the side Articulation via at least one actuator, preferably at least one Actuating cylinder to the lateral deflection of the roller regardless of geometric specifications such as length and attachment points of the linkage and to be able to adjust the stroke of the lifting device.

Für einen jeweiligen Filzwechsel sind die Hubeinrichtung und ggf. das Stellglied so ansteuerbar und/oder regelbar, daß die zu verlagernde Walze zumindest im wesentlichen nur vertikal bewegt wird. Dabei kann die seitliche Anlenkung bzw. das Stellglied zumindest im wesentlichen kraftfrei sein. Dadurch wird erreicht, daß beim Absenken der Walze die Zentrierung zur Gegenwalze exakt erfolgt.For a respective felt change, the lifting device and possibly that Actuator can be controlled and / or regulated so that the roller to be displaced is moved at least essentially only vertically. The side Articulation or the actuator at least substantially without force his. This ensures that the centering when lowering the roller to the counter-roll exactly.

In bestimmten Fällen ist es von Vorteil, wenn die Hubeinrichtung und das Stellglied in kombinierter Weise derart ansteuerbar und/oder regelbar sind, daß die Walze zumindest zeitweise in einer von der vertikalen abweichenden Richtung verlagert wird.In certain cases, it is advantageous if the lifting device and the Actuator can be controlled and / or regulated in a combined manner are that the roller at least temporarily in a different from the vertical Direction is shifted.

Von Vorteil ist auch, wenn die Walze über das Stellglied unabhängig vom Hub der Hubeinrichtung seitlich auslenkbar ist. Dies ist beispielsweise dann von Vorteil, wenn eine weitere, darunterliegende Walze ausgewechselt werden soll. Unabhängig vom Hub der Hubeinrichtung ist dann eine hinreichend weite seitliche Auslenkung der oben liegenden Walze möglich.It is also advantageous if the roller is independent of the actuator Stroke of the lifting device can be deflected laterally. For example, this is then an advantage if another roller underneath is replaced shall be. Independent of the stroke of the lifting device is then one Sufficient lateral deflection of the roller above is possible.

Grundsätzlich kann jedem einem jeweiligen Walzenende zugeordneten Lagerbock jeweils wenigstens eine Hubvorrichtung zugeordnet sein. Ebenso kann im Bereich beider Walzenenden jeweils eine seitliche Anlenkung erfolgen. In principle, each bearing block assigned to a respective roller end can at least one lifting device can be assigned. As well a lateral articulation can take place in the area of both roller ends.

The invention is explained below using an exemplary embodiment with reference to the drawing; in this show:
Figure 1

is a schematic side view of the device of Figure 1 when changing the roller below.

Figur 1 zeigt in schematischer Seitenansicht eine Vorrichtung 10 zur Positionierung und/oder Verlagerung einer in einer Pressenanordnung 12 einer Papiermaschine eingesetzten oben liegenden Walze 14. Im vorliegenden Fall umfaßt die Pressenanordnung zwei Preßwalzen. Dabei ist die zweite Walze 16 schräg unterhalb der Walze 14 angeordnet. Figure 1 shows a schematic side view of a device 10 for positioning and / or relocating one in a press arrangement 12 a paper machine used overhead roller 14. In the present In this case, the press arrangement comprises two press rolls. Here is the second roller 16 arranged obliquely below the roller 14.

Die Vorrichtung 10 umfaßt wenigstens eine an einem Maschinengestell 18 abgestützte Hubeinrichtung 20, die einerseits an dem Maschinengestell 18 und andererseits an einem der oben liegenden Walze 14 zugeordneten Lagerbock 22 angelenkt ist. Die Hubeinrichtung 20 umfaßt im vorliegenden Fall wenigstens einen Hubzylinder 20'.The device 10 comprises at least one on a machine frame 18 supported lifting device 20, which on the one hand on the machine frame 18th and on the other hand on a bearing block assigned to the overhead roller 14 22 is articulated. The lifting device 20 comprises in the present Case at least one lifting cylinder 20 '.

Wie anhand der Figur 1 zu erkennen ist, ist die Hubeinrichtung 20 sowohl an dem Maschinengestell 18 als auch an dem der Walze 14 zugeordneten Lagerbock 22 jeweils allgemein quer zur Lastrichtung und Walzenachse verschiebbar befestigt. In der Figur 1 ist die Verschieberichtung jeweils durch einen Pfeil F und F' angedeutet.As can be seen from FIG. 1, the lifting device 20 is both on the machine frame 18 as well as on that assigned to the roller 14 Bearing bracket 22 each generally transverse to the load direction and roller axis slidably attached. In Figure 1, the direction of displacement is in each case indicated by an arrow F and F '.

Beim vorliegenden Ausführungsbeispiel sind an dem Maschinengestell 18 bzw. dem Lagerbock 14 geführte schieberartige Koppelelemente 24 bzw. 26 vorgesehen, an denen die Hubeinrichtung 20 angelenkt ist. Die betreffenden Anlenkpunkte 28, 30 sind demnach an den beiden schieberartigen Koppelelementen 24, 26 definiert. Über die schieberartigen Koppelelemente 24, 26 ist somit die Krafteinleitung optimal zum Walzenschwerpunkt S einstellbar.In the present exemplary embodiment, the machine frame 18 or the bearing block 14 guided slide-like coupling elements 24 or 26 are provided, on which the lifting device 20 is articulated. The concerned Articulation points 28, 30 are accordingly on the two slide-like Coupling elements 24, 26 defined. About the slide-like coupling elements 24, 26 is the optimal application of force to the center of gravity S adjustable.

Der zwischen der Hubeinrichtung 20 und dem Maschinengestell 18 vorgesehene obere Anlenkpunkt 28 ist im vorliegenden Fall so gewählt, daß die sich aufgrund einer lastbedingten Verformung des Maschinengestells 18 ergebende horizontale Verlagerung der oben liegenden Walze 14 auf ein Minimum reduziert ist (vgl. auch Figur 2).The one provided between the lifting device 20 and the machine frame 18 upper pivot point 28 is selected in the present case so that the due to a load-related deformation of the machine frame 18 resulting horizontal displacement of the roller 14 on top Minimum is reduced (see also Figure 2).

Am Bereich ihres an dem Lagerbock 22 angelenkten Endes ist die Hubeinrichtung 20 zudem seitlich an dem Maschinengestell 18 angelenkt. Die seitliche Auslenkung erfolgt über wenigstens ein Stellglied 32, das im vorliegenden Fall wenigstens einen Stellzylinder 32' umfaßt.The lifting device is at the region of its end articulated on the bearing block 22 20 also articulated laterally on the machine frame 18. The lateral deflection takes place via at least one actuator 32, which in the present Case comprises at least one actuating cylinder 32 '.

Auch am gegenüberliegenden Ende der Walze 14 kann wieder ein von einer entsprechenden Hubeinrichtung 20 und einem entsprechenden Stellglied 32 beaufschlagter Lagerbock 22 vorgesehen sein. Demzufolge kann jedem einem jeweiligen Walzenende zugeordneten Lagerbock 22 jeweils wenigstens eine Hubvorrichtung 32 zugeordnet sein. Zudem kann im Bereich beider Walzenenden jeweils eine seitliche Anlenkung erfolgen.Also at the opposite end of the roller 14, one of one corresponding lifting device 20 and a corresponding actuator 32 acted bearing block 22 may be provided. As a result each bearing block 22 assigned to a respective roller end at least one lifting device 32 may be assigned. In addition, in the area a lateral articulation takes place at both roller ends.

Figur 2 zeigt eine schematische Seitenansicht der Vorrichtung 10 gemäß der Figur 1 bei einem Filzwechsel. Für einen solchen Filzwechsel ist die Hubeinrichtung 20 im vorliegenden Fall mittels einer geeigneten Steuereinrichtung so ansteuerbar und/oder regelbar, daß die zu verlagernde oben liegende Walze 14 zumindest im wesentlichen nur vertikal bewegt wird. Das Stellglied 32 kann für einen jeweiligen Filzwechsel zumindest im wesentlichen kraftfrei sein. Dadurch wird erreicht, daß beim Absenken der Walze 14 die Zentrierung zur Gegenwalze 16 exakt erfolgt. Die Stuhlung 18 kann sich nach dem Absenken der Walze 14 wieder in ihre Ausgangslage zurückverformen, so daß die Zwischenstücke 37 wieder problemlos eingebaut werden können.FIG. 2 shows a schematic side view of the device 10 according to FIG 1 in a felt change. For such a felt change it is Lifting device 20 in the present case by means of a suitable control device controllable and / or adjustable so that the one to be relocated roller 14 at the top is moved at least essentially only vertically becomes. The actuator 32 can at least for a respective felt change be essentially power-free. This ensures that when lowering the Roller 14 is centered on the counter roller 16 exactly. The chair 18 can return to its initial position after the roller 14 has been lowered deform back so that the intermediate pieces 37 again without problems can be installed.

Anhand dieser Figur 2 ist auch nochmals zu erkennen, daß selbst bei einer Verformung X des Stuhlungssystems bzw. des Maschinengestells 18 keine wesentliche Veränderung der Position der Walze 14 in horizontaler Richtung erfolgt. On the basis of this figure 2 can also be seen again that even with one Deformation X of the chair system or of the machine frame 18 no significant change in the position of the roller 14 in the horizontal Direction.

Nachdem die seitliche Anlenkung an der Stuhlung bzw. dem Walzengestell 18 durch wenigstens ein Stellglied 32 erfolgt, kann die seitliche Auslenkung der oben liegenden Walze 14 unabhängig von geometrischen Vorgaben wie Länge und Befestigungspunkten der Anlenkung sowie Hub der Hubeinrichtung 20 zusätzlich eingestellt werden.After the lateral linkage to the frame or the roller frame 18 by at least one actuator 32, the lateral deflection the overhead roller 14 regardless of geometric specifications such as length and attachment points of the linkage and stroke of the Lifting device 20 can also be adjusted.

Grundsätzlich können die Hubeinrichtung 20 und das Stellglied 22 über die betreffende Steuereinrichtung in kombinierter Weise auch derart ansteuerbar und/oder regelbar sein, daß die oben liegende Walze 14 zumindest zeitweise in einer von der Vertikalen abweichenden Richtung verlagert wird.Basically, the lifting device 20 and the actuator 22 can the control device in question can also be controlled in a combined manner and / or be controllable that the roller 14 at the top at least temporarily shifted in a direction deviating from the vertical becomes.

Wie anhand der Figur 3 zu erkennen ist, kann die oben liegende Walze 14 mittels des wenigstens einen Stellglieds 32 für einen Wechsel der unten liegenden Walze 16 insbesondere unabhängig vom Hub der Hubeinrichtung 20 seitlich weit ausgelenkt werden.As can be seen from FIG. 3, the roller 14 located at the top can by means of the at least one actuator 32 for changing the bottom lying roller 16 in particular regardless of the stroke of the lifting device 20 are widely deflected sideways.

Wie anhand der Figuren 1 bis 3 zu erkennen ist, ruht auch die unten liegende Walze 16 an ihren Enden jeweils in einem Lagerbock 34. Zwischen den der oberen Walze 14 sowie der unteren Walze 16 zugeordneten Lagerböcken 22, 34 können Zentriermittel 36 (vgl. insbesondere Figur 1) vorgesehen sein, durch die die beiden Walzen 14, 16 im montierten Zustand in dem Sinne zentriert sind, daß die beiden Achsen zueinander zumindest im wesentlichen parallel sind. As can be seen from FIGS. 1 to 3, the one below is also at rest Roller 16 at its ends in a bearing block 34. Between the bearing blocks associated with the upper roller 14 and the lower roller 16 22, 34 centering means 36 (cf. in particular FIG. 1) can be provided be through which the two rollers 14, 16 in the assembled state in are centered in the sense that the two axes are at least in relation to each other are essentially parallel.
