Description

Die vorliegende Erfindung betrifft eine Medienkupplung für ein mittels einer Verriegelungseinrichtung in einem Walzenständer verriegelbares Walzeneinbaustück, wobei die Medienkupplung einen ersten am Walzeneinbaustück angeordneten Kupplungsteil und einen zweiten am Walzenständer angeordneten Kupplungsteil aufweist, der zum Anschluss einer externen Medienleitung an eine am Walzeneinbaustück ausgebildeten Medienleitung dient.The present invention relates to a media coupling for a roll chock which can be locked in a roll stand by means of a locking device, wherein the media coupling has a first coupling part arranged on the roll chock and a second coupling part arranged on the roll stand which serves to connect an external media line to a media line formed on the roll chock.

Zum Betrieb von in einem Walzgerüst angeordneten Walzen sind diese mit ihren Walzenzapfen in Walzeneinbaustücken gelagert, die insbesondere zur Ölversorgung der Lager mit Medienanschlüssen versehen sind. Walzgerüste werden in der Regel als Quarto- oder Sexto-Walzgerüste ausgeführt. Zum Austausch der Arbeits- und Stützwalzen eines Quarto-Walzgerüstes oder der Arbeits-, Stütz- und Zwischenwalzen eines Sexto-Walzgerüstes werden die Walzen als bauliche Montageeinheit zusammen mit den Walzeneinbaustücken gehandhabt, wobei insbesondere im Fall der Arbeitswalzen aufgrund des im Walzbetrieb erfolgenden Verschleißes ein mehrfacher Austausch der Arbeitswalzen während eines Schichtbetriebs erforderlich werden kann. Jeder Walzenaustausch bedingt ein Abtrennen und Wiederanschließen der Medienanschlüsse, wobei zwar inzwischen technische Lösungen bekannt sind, so dass ein hiermit verbundener Kupplungsvorgang vom Bedienpersonal nicht mehr manuell durchgeführt werden muss, sondern Vorrichtungen zur Verfügung stehen, die aufgrund entsprechend ausgebildeter Medienkupplungen einen automatischen Kupplungsvorgang ermöglichen.For the operation of rolls arranged in a roll stand, these are mounted with their roll necks in roll chocks, which are provided in particular for oil supply of the bearing with media connections. Roll stands are usually designed as quarto or sexto rolling mills. To replace the working and support rollers of a four-high stand or the working, support and intermediate rolls of a six-high rolling stand, the rolls are handled as a structural assembly unit together with the roll chocks, in particular in the case of the work rolls due to the wear occurring during rolling a multiple Replacement of the work rolls during a shift operation may be required. Each roller replacement requires a disconnection and reconnection of the media connections, although now known technical solutions, so that a related coupling operation by the operator no longer has to be performed manually, but devices are available that allow an automatic coupling process due to appropriately trained media couplings.

So ist beispielsweise aus der DE 102 18 393 A1 eine Medienkupplung bekannt, die vor der Positionierung der Walzeneinbaustücke im Walzenständer oder vor der Entfernung der Walzeneinbaustücke aus dem Walzenständer ein Ankoppeln der Medienanschlüsse an das Walzeneinbaustück durch eine mittels eines Aktuators ausgeführte Zustellbewegung ermöglicht, die quer zu den Walzenachsen erfolgt.For example, from the DE 102 18 393 A1 a media coupling is known, which allows the positioning of the roll chocks in the roll stand or before the removal of the roll chocks from the roll stand coupling the media connections to the roll chock by an executed by means of an actuator feed movement, which is transverse to the roll axes.

Die EP 0 947 255 A1 zeigt eine Medienkupplung, bei der zur Ankupplung von Medienanschlüssen ein Kupplungsteil durch eine von einem Aktuator ausgeführte Zustellbewegung in Walzenachsenrichtung mit einem am Walzeneinbaustück ausgebildeten Kupplungsteil gepaart wird.The EP 0 947 255 A1 shows a media coupling, in which for coupling of media connections, a coupling part is paired by an executed by an actuator feed movement in the roll axis direction with a coupling piece formed on the roll chock.

Den beiden vorgenannten Ausführungen von Medienkupplungen ist gemeinsam, dass die Kupplungsbewegung jeweils von einem Aktuator ausgeführt wird, der als zusätzliches Stellglied neben den ohnehin für den Betrieb des Walzwerks erforderlichen Stellgliedern installiert ist. Hieraus ergibt sich nicht nur ein zusätzlicher apparativer Aufwand, sondern darüber hinaus auch die Notwendigkeit, eine Ansteuerung des Stellgliedes bereitzustellen, die sicherstellt, dass der Kupplungsvorgang zu einem definierten Zeitpunkt erfolgt, also etwa dann, wenn die Walzeneinbaustücke nach einem Walzentausch im Walzenständer positioniert sind.The two above-mentioned embodiments of media couplings have in common that the coupling movement is carried out in each case by an actuator which is installed as an additional actuator in addition to the already required for the operation of the rolling mill actuators. This results in not only an additional expenditure on equipment, but also the need to provide a control of the actuator, which ensures that the coupling process takes place at a defined time, so for example when the roll chocks are positioned after a roller exchange in the roll stand.

Aufgabe der vorliegenden Erfindung ist es daher, eine Medienkupplung bereitzustellen, die einen Kupplungsvorgang mit vergleichsweise geringem apparativen Aufwand und Steuerungsaufwand ermöglicht.Object of the present invention is therefore to provide a media coupling that allows a coupling process with relatively little equipment and control effort.

Zur Lösung dieser Aufgabe weist die erfindungsgemäße Medienkupplung die Merkmale des Anspruchs 1 auf.To solve this problem, the media coupling according to the invention has the features of claim 1.

Erfindungsgemäß wird eine am Walzenständer vorgesehene Verriegelungseinrichtung, die zur Verriegelung, also Fixierung der Walzeneinbaustücke im Walzenständer dient, nicht nur zur Ausführung der Verriegelungsbewegung verwendet, sondern auch zur Ausführung einer Kopplungsbewegung zwischen dem ersten Kupplungsteil und dem zweiten Kupplungsteil.According to the invention, a locking device provided on the roll stand, which serves for locking, thus fixing the roll chocks in the roll stand, not only used to perform the locking movement, but also for carrying out a coupling movement between the first coupling part and the second coupling part.

Hieraus ergibt sich nicht nur der Vorteil, dass zur Ausführung der Kopplungsbewegung ein ohnehin am Walzenständer bereits vorhandener Aktuator verwendet wird, sondern auch der weitere Vorteil, dass aufgrund der Verwendung ein und desselben Antriebs für die Verriegelung und die Ausführung der Kupplungsbewegung eine absolute Synchronität der Vorgänge gegeben ist, sodass eine gesonderte Ansteuerung für die Ausführung der Kopplungsbewegung nicht notwendig ist.This results in not only the advantage that an already existing on the roll stand actuator is used to perform the coupling movement, but also the further advantage that due to the use of the same drive for the locking and the execution of the coupling movement an absolute synchrony of the processes is given, so that a separate control for the execution of the coupling movement is not necessary.

Bei einer bevorzugten Ausführungsform wirkt der zweite Kupplungsteil zur Ausführung der Kopplungsbewegung zwischen dem ersten Kupplungsteil und dem zweiten Kupplungsteil mit einem Aktuator zusammen, der durch einen Aktuator der Verriegelungseinrichtung gebildet ist.In a preferred embodiment, the second coupling part for performing the coupling movement between the first coupling part and the second coupling part cooperates with an actuator, which is formed by an actuator of the locking device.

Als besonders vorteilhaft erweist es sich, wenn ein Stellgetriebe zur Ausführung der Kopplungsbewegung zumindest anteilig aus einem Stellgetriebe der Verriegelungseinrichtung gebildet ist, sodass nicht nur ein gemeinsamer Antrieb zur Betätigung der Verriegelungseinrichtung und Ausführung der Kopplungsbewegung verwendbar ist, sondern darüber hinaus auch der Aufwand zur Ausbildung eines Stellgetriebes für die Ausführung der Kopplungsbewegung reduziert werden kann.It proves to be particularly advantageous if an actuating gear for executing the coupling movement is formed at least partially from a control gear of the locking device, so that not only a common drive for actuating the locking device and execution of the coupling movement is usable, but beyond the effort to form a Stellgetriebes for the execution of the coupling movement can be reduced.

Wenn der zweite Kupplungsteil zumindest ein zur Paarung mit einem Gegenkupplungselement des ersten Kupplungsteils bestimmtes Kupplungselement aufweist, das mit einem Riegelelement der Verriegelungseinrichtung verbunden ist, derart, dass bei einer Überführung des Riegelelements in eine Verriegelungsstellung zwangsläufig eine Paarung zwischen dem Kupplungselement und dem Gegenkupplungselement hergestellt wird, kann das Stellgetriebe zur Ausführung der Kopplungsbewegung einschließlich des am Stellgetriebe der Verriegelungseinrichtung ausgebildeten Riegelelements vollständig aus dem Stellgetriebe der Verriegelungseinrichtung gebildet sein.When the second coupling part has at least one intended for mating with a counter-coupling element of the first coupling part coupling element, which with a locking element of the locking device is connected, such that upon a transfer of the locking element in a locking position inevitably a pairing between the coupling element and the counter-coupling element is produced, the actuating gear for carrying out the coupling movement including the formed on the actuating gear of the locking device locking element can be formed entirely from the actuating mechanism of the locking device.

Vorzugsweise ist das Kupplungselement des zweiten Kupplungsteils an einem Kupplungselementträger angeordnet, der vertikal verschiebbar an einer mit dem Riegelelement verbundenen Vertikalführung angeordnet ist, sodass trotz Verbindung des Kupplungselements mit dem Riegelelement aufgrund des vertikalen Freiheitsgrades eine Relativbewegung des Kupplungselements möglich ist, um bei geschlossener Medienkupplung eine vertikale Zustellbewegung des Walzeneinbaustücks zur Einstellung eines definierten Walzspaltes zwischen einander gegenüberliegenden Arbeitswalzen zu ermöglichen.Preferably, the coupling element of the second coupling part is arranged on a coupling element carrier, which is arranged vertically displaceable on a vertical guide connected to the locking element, so that despite connection of the coupling element with the locking element due to the vertical degree of freedom, a relative movement of the coupling element is possible to a vertical when the media coupling is closed To enable feed movement of the roll chock for setting a defined roll gap between opposing work rolls.

Vorzugsweise ist die Vertikalführung mit einer Arretiervorrichtung versehen, die den Kupplungselementträger in einer definierten Relativposition an der Vertikalführung fixiert, sodass der zweite Kupplungsteil in einer Walzenwechselposition fixierbar ist, um nach Austausch einer mit dem Walzeneinbaustück versehenen Walze allein mittels einer horizontalen Schließbewegung der Verriegelungseinrichtung wieder in seine dem geschlossenen Zustand der Medienkupplung entsprechende Position überführt werden zu können.Preferably, the vertical guide is provided with a locking device which fixes the coupling element carrier in a defined relative position on the vertical guide, so that the second coupling part is fixable in a roll change position, to exchange for a provided with the roll chock roller alone by means of a horizontal closing movement of the locking device back into his be transferred to the closed state of the media coupling corresponding position.

Um die Medienkupplung zur Ausbildung von Medienkreisläufen und/oder zur Ausbildung von Medienanschlüssen für unterschiedliche Medien verwenden zu können, erweist es sich als vorteilhaft, wenn der Kupplungselementträger zur Anordnung einer Mehrzahl von Kupplungselementen dient, die in ihrer Relativanordnung übereinstimmend mit einer Mehrzahl von an einem Gegenkupplungsträger am Walzeneinbaustück angeordneten Gegenkupplungselementen angeordnet sind. Insbesondere können dabei die Kupplungselemente sowie die entsprechenden Gegenkupplungselemente entsprechend den unterschiedlichen Medien unterschiedlich ausgebildet sein, sodass die Medienkupplung nicht nur zur Herstellung einer Verbindung zwischen Ölleitungen dient, die eine Ölversorgung der Walzenlager ermöglichen, sondern auch zur Verbindung elektrischer Leitungen oder Signalleitungen verwendbar ist. Damit besteht insbesondere die Möglichkeit, die Medienkupplung als zentrale Kupplung auszugestalten, die sämtliche für den Betrieb des Walzwerks erforderliche externe Zuleitungen mit am Walzwerk angeordneten Leitungen verbindet.In order to use the media coupling for the formation of media circuits and / or for the formation of media connections for different media, it proves to be advantageous if the coupling element carrier is used to arrange a plurality of coupling elements, which coincide in their relative arrangement with a plurality of on a counter-coupling carrier arranged on the roll chock counter-coupling elements are arranged. In particular, you can do this the coupling elements and the corresponding counter-coupling elements are designed differently according to the different media, so that the media coupling not only serves to establish a connection between oil lines, which allow an oil supply to the roller bearings, but also for connecting electrical lines or signal lines is used. This makes it possible in particular to design the media coupling as a central coupling, which connects all required for the operation of the rolling mill external leads arranged on the rolling mill lines.

Nachfolgend wird eine bevorzugte Ausführungsform der Erfindung anhand der Zeichnungen näher erläutert.Hereinafter, a preferred embodiment of the invention will be explained in more detail with reference to the drawings.

In den Fig. 1 und 2 ist eine zwischen einem Walzeneinbaustück 10 einer Arbeitswalze 14 und einem Walzenständer 11 angeordnete Medienkupplung 12 dargestellt, die im vorliegenden Fall die Ölversorgung eines hier nicht näher dargestellten, im Walzeneinbaustück 10 ausgebildeten Walzenlagers ermöglicht, das zur Lagerung eines Walzenzapfens 13 der Arbeitswalze 14 dient.In the Fig. 1 and 2 a arranged between a roll chock 10 a work roll 14 and a roll stand 11 media coupling 12 is shown, which in the present case, the oil supply of a not shown here, formed in the roll chock 10 roller bearing allows, which serves for the storage of a roll neck 13 of the work roll 14.

Aus Gründen der vereinfachten Darstellung ist in den Fig. 2 bis 4 lediglich eine Arbeitswalzenpaarung mit zwei Arbeitswalzen 14 dargestellt, die jeweils mit ihren Walzenzapfen 13 in Walzeneinbaustücken 10 gelagert sind. Tatsächlich befindet sich die Arbeitswalzenpaarung bei einem Quarto-Walzgerüst zwischen zwei hier nicht näher dargestellten Stützwalzen, die wie die Arbeitswalzen 14 mit ihren Walzenzapfen in Walzeneinbaustücken 10 angeordnet sind; bei einem Sexto-Walzgerüst befinden sich die Arbeitswalzen 14 zwischen Zwischenwalzen, die jeweils zwischen einer Arbeitswalze und einer Stützwalze angeordnet sind. Die Zwischenwalzen sind dabei mit ihren Walzenzapfen in Zwischenwalzeneinbaustücken angeordnet.For the sake of simplified illustration is in the Fig. 2 to 4 only a pair of work rolls with two work rolls 14 shown, which are each stored with their roll necks 13 in roll chocks 10. In fact, the pair of work rolls in a four-high stand is located between two support rollers, not shown here, which are arranged like the work rolls 14 with their roll necks in roll chocks 10; in a six-high rolling stand, the work rolls 14 are located between intermediate rolls, which are each arranged between a work roll and a back-up roll. The intermediate rolls are arranged with their roll necks in Zwischenwalzeneinbaustücken.

In der Arbeitsstellung der Arbeitswalzen 14 befindet sich die in Fig. 2 dargestellte Medienkupplung 12 in ihrer Schließstellung, in der zwischen einem ersten am Walzeneinbaustück 10 angeordneten Kupplungsteil 16 und einem zweiten am Walzenständer 11 angeordneten Kupplungsteil 17 ein Kupplungseingriff ausgebildet ist, derart, dass am zweiten Kupplungsteil 17 ausgebildete Kupplungselemente 18, 19, die im vorliegenden Fall als Kupplungsstecker ausgebildet sind, in als Kupplungsbuchsen ausgebildete Gegenkupplungselemente 20, 21 des ersten Kupplungsteils 16 eingreifen.The roll chocks 10 are located in the in Fig. 2 shown working position of the work rolls 14 for forming a roll gap 15 in a working position. In the working position of the work rolls 14 is located in Fig. 2 shown media coupling 12 in its closed position, in which between a first arranged on the roll chock 10 coupling member 16 and a second arranged on the roll stand 11 coupling member 17 is formed a coupling engagement, such that formed on the second coupling member 17 coupling elements 18, 19, in the present case as Coupling plug are formed, engage in designed as a coupling sleeves mating coupling elements 20, 21 of the first coupling part 16.

Die Kupplungselemente 18, 19 und Gegenkupplungselemente 20, 21 sind als Leitungsanschlussstücke ausgebildet, an die hier nicht näher dargestellte Leitungen anschließen, welche beispielsweise eine Ölversorgung der Walzenlager ermöglichen, derart, dass etwa durch die Paarung des Kupplungselements 18 mit dem Gegenkupplungselement 20 eine Ölzufuhr 22 und durch die Paarung des Gegenkupplungselements 21 mit dem Kupplungselement 19 ein Ölrückfluss 23 ermöglicht wird.The coupling elements 18, 19 and mating coupling elements 20, 21 are formed as line fittings, connect to the lines not shown here, which allow, for example, an oil supply to the roller bearings, such that approximately by the pairing of the coupling element 18 with the counter-coupling element 20, an oil supply 22 and by the pairing of the counter-coupling element 21 with the coupling element 19, an oil return flow 23 is made possible.

Wie aus einer Zusammenschau der Fig. 1 und 2 deutlich wird, ist an dem Walzenständer 11 eine Verriegelungseinrichtung 24 angeordnet, die als wesentliche Bestandteile einen, hier als Hydraulikzylinder ausgebildeten Aktuator 25 sowie ein über ein Stellgetriebe 26 mit dem Aktuator 25 verbundenes Riegelelement 27 aufweist, das in einer in Fig. 1 dargestellten Verriegelungsposition, in der das Riegelelement 27 in eine am Walzeneinbaustück 10 als vertikale Nut ausgebildete Riegelfalle 28 eingreift, die die axiale Position der Arbeitswalze 14 im Walzenständer 11 sichert.As if from a synopsis of Fig. 1 and 2 becomes clear, a locking device 24 is arranged on the roll stand 11, which has as essential components a, here designed as a hydraulic cylinder actuator 25 and a connected via a control gear 26 to the actuator 25 locking element 27 which in an in Fig. 1 illustrated locking position in which the locking element 27 engages in a formed on the roll chock 10 as a vertical groove latch bolt 28 which secures the axial position of the work roll 14 in the roll stand 11.

Um eine Entnahme der in Fig. 1 in der Arbeitsstellung im Walzenständer 11 aufgenommenen Stützwalze 14 aus dem Walzenständer 11 zu ermöglichen, wird das Riegelelement 27 mittels Betätigung des Aktuators 25 aus der Riegelfalle 28 entfernt, sodass anschließend die Arbeitswalze 14 in axialer Richtung dem Walzenständer 11 entnommen werden kann, um einen Walzenwechsel durchführen zu können. Hierzu wird nach erfolgter Entnahme eine neue Arbeitswalze 14 axial in den Walzenständer 11 eingeführt, derart, dass das Walzeneinbaustück 10 wieder in der in Fig. 1 dargestellten Position in einem Ständerfenster 29 des Walzenständers aufgenommen wird und das Riegelelement 27 durch Betätigung des Aktuators 25 wieder in seine Verriegelungsposition überführt wird.To a removal of in Fig. 1 in the working position in the roll stand 11 recorded support roller 14 to allow the roll stand 11, the locking element 27 is removed by actuation of the actuator 25 from the latch bolt 28 so that then the work roll 14 can be removed in the axial direction of the roll stand 11 to perform a roll change to be able to. For this purpose, a new work roll 14 is axially inserted into the roll stand 11 after removal, so that the roll chock 10 again in the in Fig. 1 shown position is received in a stator window 29 of the roll stand and the locking element 27 is transferred by actuation of the actuator 25 back into its locking position.

Nach erfolgter Verriegelung werden die Arbeitswalzen 14 zur Einstellung des gewünschten Walzspaltes 15 aus der Walzenwechselposition wieder in ihre in Fig. 2 dargestellte Arbeitsstellung überführt, wobei die Walzeneinbaustücke 10 in den Ständerfenstern 29 vertikal gegenüber den Riegelelementen 27 bewegt werden.After locking, the work rolls 14 to adjust the desired roll gap 15 from the roll change position back into their in Fig. 2 transferred working position, wherein the roll chocks 10 are moved vertically in the stator windows 29 relative to the locking elements 27.

Wie weiter aus einer Zusammenschau der Fig. 1 und 2 deutlich wird, weist der zweite Kupplungsteil 17 zur Anordnung der Kupplungselemente 18, 19 einen Kupplungselementträger 30 auf, der über ein im vorliegenden Fall starr ausgebildetes Getriebeelement 31 an das Stellgetriebe 26 der Verriegelungseinrichtung 24 angeschlossen ist. Im vorliegenden Fall ist hierzu der Kupplungselementträger 30 über das Getriebeelement 31 direkt mit dem Riegelelement 27 der Verriegelungseinrichtung 24 verbunden. Als Folge hiervon erfolgt synchron mit einer Verriegelungsbewegung der Verriegelungseinrichtung 24, die durch den Aktuator 25 bewirkt wird, eine Kopplungsbewegung zwischen dem ersten Kupplungsteil 16 und dem zweiten Kupplungsteil 17, bei der gleichzeitig mit der Eingriffsbewegung des Riegelelements 27 in die Riegelfalle 28 eine Eingriffsbewegung der Kupplungselemente 18, 19 in die an einem Gegenkupplungsträger 36 angeordneten Gegenkupplungselemente 20, 21 erfolgt. Ebenfalls synchron erfolgt bei einer Entriegelungsbewegung, bei der das Riegelelement 27 der Verriegelungseinrichtung 24 aus der Riegelfalle 28 herausbewegt wird, eine Entkopplungsbewegung zwischen dem ersten Kupplungsteil 16 und dem zweiten Kupplungsteil 17, bei der die Kupplungselemente 18, 19 aus den Gegenkupplungselementen 20, 21 herausbewegt werden.How further from a synopsis of Fig. 1 and 2 becomes clear, the second coupling part 17 for the arrangement of the coupling elements 18, 19 a coupling element carrier 30 which is connected via a rigidly formed in this case gear element 31 to the actuating gear 26 of the locking device 24. In the present case, this is the coupling element carrier 30 via the transmission element 31 directly to the locking element 27 of the locking device 24th connected. As a result, in synchronism with a locking movement of the locking device 24, which is effected by the actuator 25, a coupling movement between the first coupling part 16 and the second coupling part 17, at the same time as the engagement movement of the locking element 27 in the latch bolt 28, an engagement movement of the coupling elements 18, 19 in the arranged on a mating coupling carrier 36 counter-coupling elements 20, 21 takes place. Also synchronously takes place during an unlocking movement in which the locking element 27 of the locking device 24 is moved out of the latch bolt 28, a decoupling movement between the first coupling part 16 and the second coupling part 17, in which the coupling elements 18, 19 are moved out of the counter-coupling elements 20, 21 ,

Zwischen dem Kupplungselementträger 30 und dem Getriebeelement 31 ist eine Vertikalführung 32 ausgebildet, derart, dass wie bei einem Vergleich der Fig. 2 und 3 deutlich wird, der Kupplungselementträger 30 mit den daran angeordneten Kupplungselementen 18, 19 einer Vertikalbewegung des Walzeneinbaustücks 10 im Ständerfenster 29 des Walzenständers 11 folgen kann, ohne dass die Verbindung zwischen dem Kupplungselementträger 30 und dem Stellgetriebe 26 der Verriegelungseinrichtung 24 gelöst wird.Between the coupling element carrier 30 and the transmission element 31, a vertical guide 32 is formed, such that as in a comparison of Fig. 2 and 3 it becomes clear that the coupling element carrier 30 with the coupling elements 18, 19 arranged thereon can follow a vertical movement of the roll chock 10 in the stator window 29 of the roll stand 11, without the connection between the coupling element carrier 30 and the adjusting mechanism 26 of the locking device 24 being released.

Fig. 3 zeigt das in Fig. 2 in der Arbeitsstellung angeordnete Walzeneinbaustück 10 in einer Walzenwechselposition, in der die Arbeitswalzen 14 in eine definierte vertikale Position verfahren sind und in der, wie bereits vorstehend erwähnt, ein Austausch der Arbeitswalzen erfolgt. Hierzu wird das Walzeneinbaustück 10 durch Betätigung des Aktuators 25 entriegelt, also das Riegelelement 27 aus der Riegelfalle 28 herausbewegt. Bevor die Entriegelung des Walzeneinbaustücks 10 erfolgt, wird ein am Getriebeelement 31 angeordneter, als Arretiereinrichtung 33 wirkender Schließzylinder mit einem Schließbolzen 34 durch einen Führungsschlitz 35 der Vertikalführung 32 hindurch in eine Riegelöffnung 37 des Kupplungselementträgers 30 verfahren, sodass der Kupplungselementträger 30 in seiner vertikalen Relativposition gegenüber dem Getriebeelement 31 und somit ebenfalls gegenüber dem Riegelelement 27 der Verriegelungseinrichtung 24 fixiert ist. Erst anschließend erfolgt eine Entriegelungsbewegung des Riegelelements 27 in die in Fig. 4 dargestellte Entriegelungsposition, wobei gleichzeitig eine Entkopplung der Kupplungsteile 16, 17 erfolgt, sodass das in der Walzenwechselposition angeordnete Walzeneinbaustück 10 in axialer Richtung dem Ständerfenster 28 entnommen werden kann. Fig. 3 shows that in Fig. 2 arranged in the working position roll chock 10 in a roll change position in which the work rolls 14 are moved in a defined vertical position and in which, as already mentioned above, there is an exchange of the work rolls. For this purpose, the roll chock 10 is unlocked by actuation of the actuator 25, so the latch member 27 moved out of the latch bolt 28. Before the unlocking of the roll chock 10 takes place, a lock cylinder arranged on the transmission element 31 and acting as a locking device 33 with a locking pin 34 passes through a guide slot 35 of the vertical guide 32 into a latch opening 37 of the coupling element carrier 30 method, so that the coupling element carrier 30 is fixed in its vertical relative position relative to the transmission element 31 and thus also with respect to the locking element 27 of the locking device 24. Only then is an unlocking movement of the locking element 27 in the in Fig. 4 illustrated unlocking position, wherein at the same time a decoupling of the coupling parts 16, 17, so that the arranged in the roll change position roll chock 10 in the axial direction of the stator window 28 can be removed.

Die Arretiereinrichtung 33 stellt somit sicher, dass nach der Entkopplung der Kupplungsteile 16, 18 der zweite Kupplungsteil 17 in einer Position verbleibt, aus der dieser nach erfolgtem Walzenwechsel wieder mit einer horizontalen Kopplungsbewegung mit dem ersten Kupplungsteil 16 gepaart werden kann.The locking device 33 thus ensures that after the decoupling of the coupling parts 16, 18 of the second coupling part 17 remains in a position from which it can be paired after a roll change again with a horizontal coupling movement with the first coupling part 16.
