Description

Die vorliegende Erfindung betrifft eine Walzenrichtmaschine mit in einem Kassettenwechselsystem angeordneten Richtwalzen, nach dem Oberbegriff des Anspruchs 1.The present invention relates to a roller leveling machine with straightening rollers arranged in a cassette changing system, according to the preamble of claim 1.

Zur Verarbeitung von Bandstahl, das von einem Coil abgezogen wird bzw. auch von durch vorherige Bearbeitung verzogenen Teilen, werden herkömmlicher Weise Walzenrichtmaschinen eingesetzt. Eine derartige Walzenrichtmaschine ist beispielsweise aus der EP 1 584 384 A1 bekannt. Die dort gezeigte Richtmaschine weist einen oberen Walzenstuhl mit einer Mehrzahl von oberen Richtwalzen, einen unteren Walzenstuhl mit einer Mehrzahl von unteren Richtwalzen auf, wobei wenigstens einige der oberen und/oder unteren Richtwalzen angetrieben sind. Der Antrieb erfolgt dabei über Gelenkwellen, die an einem ihrer Enden mit der zugehörigen Richtwalze verbunden sind und an ihrem anderen Ende mittels lösbarer Kupplung mit einem ersten Verteilergetriebe verbindbar sind, wobei zum Antrieb des ersten Verteilergetriebes eine Antriebseinrichtung vorgesehen ist, die gemäß EP 1 584 384 A1 aus einem Hauptgetriebe und einem Antriebsmotor besteht.For processing strip steel, which is withdrawn from a coil or also warped by previous processing parts, roll straightening machines are conventionally used. Such a roller leveler is for example from the EP 1 584 384 A1 known. The straightening machine shown there comprises an upper roller mill having a plurality of upper straightening rollers, a lower roller mill having a plurality of lower straightening rollers, at least some of the upper and / or lower straightening rollers being driven. The drive takes place via cardan shafts which are connected at one of their ends with the associated straightening roller and at the other end by means of releasable coupling with a first transfer case are connectable, wherein for driving the first transfer case, a drive device is provided according to EP 1 584 384 A1 consists of a main gear and a drive motor.

Beim Einsatz einer Richtmaschine in einer Anlage auf der ein sehr großes Spektrum von Materialien hinsichtlich des Dickenbereiches, der Festigkeiten bzw. der Oberflächenbeschaffenheit oder der Materialien selbst (Aluminium, Stahl, Edelstahl, etc.) verarbeitet werden soll, ist es notwendig, die Anzahl der Richtwalzen und deren Durchmesser entsprechend dem Richtgut anzupassen.When using a straightening machine in a plant where a very wide range of materials is to be processed with regard to the thickness range, the strengths or the surface finish or the materials themselves (aluminum, steel, stainless steel, etc.), it is necessary to reduce the number of Straightening rolls and their diameter according to the straightening adapt.

Um diesen Forderungen zu begegnen, wurde gemäß EP 1 584 384 A1 vorgeschlagen, die Richtwalzen in einer Wechselkassette anzuordnen und somit den oberen und unteren Richtwalzensatz zusammen mit den zugehörigen Antriebs- bzw. Gelenkwellen in einem Schritt aus der Richtmaschine herauszubringen und eine andere Wechselkassette mit einem entsprechenden gegebenenfalls anderen Richtwalzensatz wieder einzubringen.To meet these demands, was according to EP 1 584 384 A1 proposed to arrange the straightening rollers in a removable cassette and thus bringing out the upper and lower leveling roller set together with the associated drive or propeller shafts in one step from the straightening machine and bring back another removable cassette with a corresponding optionally different straightening roller set.

Abhängig von der Anzahl der Richtwalzen, der Achsabstände, der Walzendurchmesser und der erforderlichen Prozessdrehmomente, welche ein Richtaggregat kennzeichnen, werden dementsprechend unterschiedliche Anforderungen an das antreibende Verteilergetriebe gestellt.Depending on the number of straightening rollers, the center distances, the roller diameter and the required process torques, which characterize a straightening unit, accordingly different demands are placed on the driving transfer case.

Gemäß EP 1 584 384 A1 wird deshalb vorgeschlagen, das Verteilergetriebe in die Wechselkassette zu integrieren und zusammen mit dieser auszuwechseln.According to EP 1 584 384 A1 It is therefore proposed to integrate the transfer case in the removable cassette and replace it with this.

Diese Lösung erfordert jedoch, dass beim Bereitstellen von mehreren gleichartigen Kassetten, die nach ihrer Bauart bestimmt gemäß EP 1 584 384 A1 ein Zwischengetriebe benötigen, genau dieses bei jeder weiteren Wechselkassette vorgesehen werden muss. Außerdem muss je nach erforderlicher bzw. installierter Leistung ein Ölkühlkreislauf installiert bzw. an einem solchen angekuppelt werden. Des weiteren können Überwachungsfunktionen, wie der Öltemperatur oder des Ölfüllstands erforderlich sein, welche dann nur mit erhöhtem Aufwand in die Steuerung eingebaut werden können.However, this solution requires that when providing several similar cassettes, according to their design determined according to EP 1 584 384 A1 need an intermediate gear, exactly this must be provided with every other removable cassette. In addition, depending on the required or installed capacity, an oil cooling circuit must be installed or coupled to one. Furthermore, monitoring functions, such as the oil temperature or the oil level may be required, which can then be installed only with increased effort in the control.

Der vorliegenden Erfindung liegt deshalb die Aufgabe zugrunde, eine Walzenrichtmaschine der eingangs genannten Art zu schaffen, bei der die oben genannten Nachteile vermieden sind und sich der Ausbau der Wechselkassette möglichst einfach und kostengünstig gestaltet.The present invention is therefore an object of the invention to provide a roller leveler of the type mentioned, in which the above-mentioned disadvantages are avoided and the removal of the removable cassette designed as simple and inexpensive.

Diese Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst.This object is solved by the features of claim 1.

Gemäß der vorliegenden Erfindung zeichnet sich die Richtmaschine dadurch aus, dass wenigstens ein weiteres, zweites Verteilergetriebe vorgesehen ist, das anstelle des ersten Verteilergetriebes mit der Wechselkassette verbindbar ist. Dies führt vorteilhafterweise zu einem gegenüber dem Stand der Technik erheblich vereinfachten Wechselkassettensystem. Insbesondere wird ein einfacher Aufbau der Wechselkassette sogar bei gleichzeitiger, gegenüber dem Stand der Technik erreichten Reduzierung der benötigten Verteilergetriebe ereicht.According to the present invention, the straightening machine is characterized in that at least one further, second transfer case is provided, which is connectable to the removable cassette instead of the first transfer case. This advantageously leads to a comparison with the prior art considerably simplified removable cassette system. In particular, a simple construction of the removable cassette is achieved even with simultaneous, compared to the prior art achieved reduction of the required transfer case.

Vorteilhafterweise ist das mit den Gelenkwellen der Wechselkassette verbindbare erste Verteilergetriebe und/oder das mit den Gelenkwellen der Wechselkassette verbindbare zweite Verteilergetriebe durch Verschiebung quer zur Achsrichtung der Gelenkwellen bzw. Richtwalzen von einer Parkposition in eine Arbeitsposition und umgekehrt bringbar. Damit kann der Kassettenwechsel auch von der Antriebsseite her schnell erfolgen und führt nur zu geringen Maschinen-Umrüstzeiten.Advantageously, the first transfer case which can be connected to the cardan shafts of the exchangeable cartridge and / or the one with the cardan shafts of the exchangeable cartridge connectable second transfer case by shifting transversely to the axial direction of the propeller shafts or straightening rollers from a parking position into a working position and vice versa brought. Thus, the cassette change can also be done quickly from the drive side and only leads to low machine changeover times.

Dadurch, dass das erste Verteilergetriebe und/ oder das zweite Verteilergetriebe auf einem Schlitten angeordnet sind, der sowohl quer zur Achsrichtung der Gelenkwellen als auch in Achsrichtung verschiebbar ist, kann auf einfache und sichere Weise eine Verschiebung des für den jeweiligen Richtwalzensatz vorgesehenen Verteilergetriebes erfolgen. Dabei können in einer ersten Ausführungsform beide bzw. bei mehr als zwei Getrieben alle Getriebe auf einem Schlitten angeordnet sein.Characterized in that the first transfer case and / or the second transfer case are arranged on a carriage which is displaceable both transversely to the axial direction of the propeller shafts and in the axial direction, can be carried out in a simple and safe way, a shift provided for the respective set of straightening transfer case. In this case, in a first embodiment, both or, in the case of more than two transmissions, all transmissions may be arranged on a carriage.

In einer Ausführungsform kann die Verschiebung der Verteilergetriebe horizontal erfolgen, also in einer Ebene, die parallel zu den Ebenen der Achsen der Richtwalzen verläuft.In one embodiment, the displacement of the transfer case can be horizontal, that is, in a plane that is parallel to the planes of the axes of the straightening rollers.

Alternativ kann die Verschiebung eines oder aller Verteilergetriebe vertikal erfolgen, sodass die benötigt Breite für die Walzenrichtmaschine, je nach zur Verfügung stehendem Platz am Produktionsort, verringert werden kann.Alternatively, the displacement of one or all of the transfer cases can be vertical, so that the required width for the roller leveler can be reduced, depending on the available space at the production site.

Selbstverständlich sind auch Mischformen möglich, beispielsweise dass eines der Verteilergetriebe horizontal und das andere vertikal verschoben wird. Zusätzlich gibt es grundsätzlich die Möglichkeit der Verschiebung in einer jeglichen Winkellage, was den Vorteil hat, eine kompakte Bauweise der Walzenrichtmaschine insbesondere auch bei mehr als zwei Verteilergetrieben zu ermöglichen.Of course, mixed forms are possible, for example, that one of the transfer case is moved horizontally and the other vertically. In addition, there is basically the possibility of displacement in any angular position, which has the advantage of allowing a compact design of the roller leveling machine, especially in more than two transfer cases.

Zur Verbindung des ersten bzw. zweiten Verteilergetriebes mit einem Antriebsmotor bzw., wenn ein von einem Antriebsmotor angetriebenes Hauptgetriebe vorgesehen ist, kann die Verschiebung zusätzlich in Achsrichtung der Gelenkwellen bzw. Richtwalzen erfolgen. Dies erfolgt beispielsweise mit einem so genannten "Kreuzschlitten" der in diesen beiden Richtungen hin und her verschiebbar ausgebildet ist.In order to connect the first or second transfer case to a drive motor or, if a main drive driven by a drive motor is provided, the displacement may additionally take place in the axial direction of the drive shafts or leveling rolls. This is done, for example, with a so-called "cross slide" which is designed to be displaceable back and forth in these two directions.

Alternativ kann vorgesehen werden, dass der die Verteilergetriebe antreibende Antriebsmotor seinerseits auf einem Schlitten angeordnet ist und in Achsrichtung der Richtwalzen verschiebbar ist.Alternatively, it can be provided that the drive transmission driving the transfer case in turn is arranged on a carriage and in the axial direction of the Straightening rollers is displaceable.

In einer weiteren alternativen Ausführungsform kann zur Kupplung des Antriebsmotors mit dem zugeordneten Verteilergetriebe eine separate Wellenkupplung vorgesehen sein, mit der der Antriebsmotor mit dem in Arbeits- bzw. Antriebsposition gebrachten Verteilergetriebe zu dessen Antrieb verbindbar ist.In a further alternative embodiment, a separate shaft coupling can be provided for coupling the drive motor with the associated transfer case, with which the drive motor can be connected to the transfer case placed in working or drive position for its drive.

In einer weiteren alternativen Ausführungsform kann jedes Verteilergetriebe einen eigenen fest gekuppelten Antriebsmotor aufweisen, der sich dann entsprechend der Bewegung des gekuppelten Verteilergetriebes mit diesem mitbewegt.In a further alternative embodiment, each transfer case may have its own fixedly coupled drive motor, which then moves along with it in accordance with the movement of the coupled transfer case.
