Abstract

A rolling mill wherein the frame or frames for pairs of superimposed rolling tools can be lifted off the base by a crane. Each rolling tool carries a first clutch element receiving torque from a separable discrete second clutch element on a support which is adjacent a properly installed frame. The support is mounted on a reciprocable carriage, together with or independently of a drive for the second clutch elements, and can be moved in the axial direction of the tools toward and away from the adjacent frame. The upper second clutch element of the pair of second clutch elements on the support is movable up and down by a fluid-operated motor toward and away from a position of alignment with the corresponding first clutch element. The second clutch elements have pins which enter registering sockets in the adjacent first clutch elements, or vice versa, and the second clutch elements are axially movably mounted in their bearings on the support and are biased toward the respective first clutch elements. The second clutch elements are disengaged from the respective first clutch elements by moving the support away from the adjacent frame. A sensor cooperates with a stop to ensure that each movable second clutch element moves to a position of accurate alignment with the respective first clutch element, and the carriage can be moved toward the frame only when the alignment of the movable second clutch element with the respective first element is completed.

Description

Die Erfindung betrifft eine Profiliermaschine mit einem oder mehreren in Vorschubrichtung eines Werkstückes hintereinander angeordneten Umformrollen-Paaren, die jeweils mittels Arbeitswellen in Werkzeuggerüsten gelagert sind, neben denen ein Antrieb mit einem Getriebeblock und zwischen diesem und den ihm zugewandten Enden der Arbeitswellen in ihrer Länge durch Zusammenschieben und Auseinanderziehen verstellbare Gelenkwellen und Kupplungen als lösbare Verbindungen zwischen den Gelenkwellen und den Arbeitswellen vorgesehen sind, wobei zwischen dem jeweiligen Werkzeuggerüst und dem zugehörigen Getriebeblock ein Kupplungsgerüst oder -träger angeordnet ist, auf dessen dem Getriebeblock zugewandter Seite die Gelenkwellen und auf dessen dem Werkzeuggerüst zugewandter Seite die lösbaren Kupplungen für die Arbeitswellen angeordnet sind, und wobei die Lagerung zumindest der oberen Kupplungswelle höhenverstellbar ist.The invention relates to a profiling machine with one or more pairs of forming rollers arranged one behind the other in the feed direction of a workpiece, each of which is mounted in tool stands by means of working shafts, in addition to which a drive with a gear block and between the latter and the ends of the working shafts facing it are pushed together in their length and pulling apart adjustable cardan shafts and couplings are provided as detachable connections between the cardan shafts and the working shafts, a coupling frame or carrier being arranged between the respective tool frame and the associated gear block, on the side facing the gear block the cardan shafts and on the side facing the tool frame the releasable couplings for the working shafts are arranged, and wherein the bearing is adjustable in height at least the upper coupling shaft.

Profiliermaschinen sind bekannt und erlauben die Herstellung von Profilen auch mit relativ komplizierten Querschnitten aus Bändern oder Blechstreifen mit hoher Genauigkeit und hoher Geschwindigkeit. Beim Übergang von einem Produkt auf ein Produkt mit anderem Querschnitt ergeben sich jedoch Zeitverluste durch den Wechsel der Umformrollen, die zunächst ausgekuppelt und ausgebaut und durch neue Rollensätze ersetzt werden müssen, welche dann wiederum eingekuppelt werden müssen.Profiling machines are known and allow the production of profiles with relatively complicated cross sections from strips or sheet metal strips with high accuracy and high speed. When changing from a product to a product with a different cross-section, however, there is a loss of time due to the change of the forming rolls, which must first be disengaged and removed and replaced with new sets of rolls, which must then be engaged again.

Aus der JP-A-59 218 221, die als nächstliegender Stand der Technik angesehen wird, ist eine Profiliermaschine der eingangs erwähnten Art bekannt, bei welcher zum Auswechseln der die Umformrollen enthaltende Block in Längsrichtung der Antriebswellen aus der Kupplungsposition gebracht werden muß, bevor er abgehoben und in umgekehrter Reihenfolge durch einen neuen Werkzeugsatz ersetzt werden kann. Die Arbeitswellen und ihre Gerüste müssen also auf ihrem Unterbau zunächst verschoben werden, bis die Kupplungen gelöst sind, bevor ein Werkzeugwechsel durchgeführt werden kann.From JP-A-59 218 221, which is considered to be the closest prior art, a profiling machine of the type mentioned is known, in which the block containing the forming rollers must be removed from the coupling position in the longitudinal direction of the drive shafts before it can be replaced can be lifted off and replaced in the reverse order with a new tool set. The working shafts and their scaffolds must therefore first be moved on their substructure until the couplings are released before a tool change can be carried out.

Aus der DE-A-24 39 017 sind für solche Fälle Hilfsmittel bekannt, die das Auswechseln von Umformrollen-Paaren erleichtern sollen. Vor allem sollen dabei die beim Auswechseln solche Umformrollen notwendig werdenden Neueinstellungen und Justierarbeiten vermieden werden. Dieses Hilfsmittel besteht dabei in einer auf dem Maschinenteil abstützbaren Fixier- und Tragvorrichtung jeweils für ein Umformrollen-Paar, so daß auch damit das Auswechseln der einzelnen Umformrollen zeitaufwendig und schwierig ist. Vor allem ist dabei auch ein erheblicher Personalaufwand erforderlich.For such cases, DE-A-24 39 017 aids are known which are intended to facilitate the replacement of pairs of forming rollers. Above all, the new adjustments and adjustment work that are necessary when replacing such forming rolls are to be avoided. This aid consists in a fixation and support device, which can be supported on the machine part, for a pair of forming rollers, so that the replacement of the individual forming rollers is also time-consuming and difficult. Above all, considerable personnel expenditure is required.

Gem. der DE-A-25 56 974 wurde deshalb eine Profiliermaschine geschaffen, bei welcher zur Verkürzung von Umrüstzeiten in einem Walzgerüst zwei übereinander angeordnete Umformrollen-Paare für verschiedene Profile vorgesehen sind. Dadurch wird aber die Zahl der mit dieser Profiliermaschine herstellbaren Profile verschiedener Querschnitte auf ein Minimum beschränkt.According to DE-A-25 56 974, a profiling machine was therefore created in which, in order to shorten changeover times in a roll stand, two pairs of forming rollers arranged one above the other are provided for different profiles. As a result, however, the number of profiles of different cross sections that can be produced with this profiling machine is limited to a minimum.

Aus der DE-A-25 56 974 ist eine Lösung bekannt, bei welcher an den Ständern der Walzgerüste bzw. am Werkzeugträger Drehscheiben mit jeweils mehreren Umformrollen von Umformrollen-Paaren angeordnet sind. Dadurch ist zwar eine etwas größere Variationsmöglichkeit entsprechend der Aufnahmefähigkeit dieser Drehscheiben gegeben, jedoch ist die Anzahl der herstellbaren Profile weiterhin begrenzt. Darüber hinaus ergeben sich konstruktive Probleme beim Anordnen der Drehscheiben, die sehr genau in ihrer jeweiligen Arbeitsposition justiert werden müssen, um Fertigungsungenauigkeiten aus dem unvermeidbaren Spiel dieser Drehscheiben auszuschalten.From DE-A-25 56 974 a solution is known in which turntables, each with a plurality of forming rollers of pairs of forming rollers, are arranged on the stands of the roll stands or on the tool carrier. Although there is a somewhat greater possibility of variation depending on the capacity of these turntables, the number is of the profiles that can be produced continues to be limited. In addition, there are constructive problems with the arrangement of the turntables, which must be adjusted very precisely in their respective working position in order to eliminate manufacturing inaccuracies from the inevitable play of these turntables.

Es besteht deshalb die Aufgabe, eine Profiliermaschine der eingangs erwähnten Art zu schaffen, bei welcher einzelne oder alle Umformrollen-Paare je nach Erfordernis schnell und vollautomatisch ausgewechselt werden können, um die Stillstandzeit der Profiliermaschine auf ein Minimum zu begrenzen und dennoch nacheinander Profile unterschiedlichster Querschnitte herstellen zu können.It is therefore the task of creating a profiling machine of the type mentioned at the outset, in which individual or all forming roller pairs can be exchanged quickly and fully automatically, as required, in order to limit the downtime of the profiling machine to a minimum and still produce profiles of different cross sections in succession to be able to.

Die Lösung dieser Aufgabe besteht darin, daß das Kupplungsgerüst bzw. der Kupplungsträger zusammen mit der ihm zugewandten Kupplungshälfte quer zur Vorschubrichtung des Werkstückes und quer zur Arbeitsrichtung der Umformrollen von dem Werkzeuggerüst und der diesem zugewandten Kupplungshälfte wegbewegbar oder verschiebbar ist, daß an der Lagerung der Kupplungswelle oder am Werkzeuggerüst ein Fühler, Sensor, Schaltelement od.dgl. zum automatischen und selbsttätigen Einstellen auf die jeweilige Höhe der Gegen-Kupplungshälfte der zugehörigen Arbeitswelle vorgesehen ist und daß der Verschiebeantrieb für das Kupplungsgerüst derart angesteuert ist, daß die Verschiebebewegung zum Einkuppeln oder ihr letztes Teilstück erst nach der Höhenanpassung der Kupplungshälfte des Kupplungsgrüstes oder -trägers an die Kupplungshälfte des Werkzeuggerüstes erfolgt.The solution to this problem is that the coupling frame or the coupling carrier, together with the coupling half facing it, can be moved or displaced transversely to the feed direction of the workpiece and transversely to the working direction of the forming rollers from the tool frame and the coupling half facing this, that on the bearing of the coupling shaft or a sensor, sensor, switching element or the like on the tool frame. is provided for automatic and automatic adjustment to the respective height of the counter-coupling half of the associated working shaft and that the displacement drive for the coupling frame is controlled in such a way that the displacement movement for engaging or its last section only after the height adjustment of the coupling half of the coupling frame or carrier the coupling half of the tool frame is done.

Durch diese Maßnahmen und Merkmale ist es also möglich, ein Werkzeuggerüst mit den auswechselbaren Umformrollen-Paaren von seinem Antrieb zu lösen, ohne es selbst verschieben zu müssen. Stattdessen wird das Kupplungsgerüst oder ein Kupplungsträger mit der entsprechenden Kupplungshälfte von dem Werkzeuggerüst wegbewegt und nach dem Austausch der Umformrollen erfolgt das Einkuppeln durch eine umgekehrte Bewegung. Dabei wird die Höhe der Kupplungshälften zuvor vollautomatisch aueinander angepaßt, bevor die Verschiebebewegung des Kupplungsgerüstes od.dgl. in Arbeitsstellung erfolgt oder beendet wird. Es kann also in möglichst kurzer Zeiteinheit das komplette Rollenwerkzeug, welches aus einem oder mehreren hintereinander angeordneten Umformrollen-Paaren bestehen kann, in einem oder mehreren hintereinander angeordneten Werkzeuggerüsten schnell und vollautomatisch gewechselt werden, indem ein Werkzeuggerüst nach dem Auskuppeln gegen ein anderes ausgetauscht wird, ohne zuvor noch verschoben werden zu müssen, so daß unproduktive Stillstandszeiten, die beim Umrüsten entstehen, auf ein Minimum reduziert werden.These measures and features make it possible to detach a tool frame with the interchangeable pairs of forming rollers from its drive without having to move it yourself. Instead, the coupling frame or a coupling carrier with the Corresponding coupling half is moved away from the tool frame and, after the shaping rollers have been replaced, the coupling is carried out by a reverse movement. The height of the coupling halves is previously adjusted to each other fully automatically before the sliding movement of the coupling frame or the like. takes place in the working position or is ended. The complete roll tool, which can consist of one or more pairs of forming rolls arranged one behind the other, can be quickly and fully automatically changed in one or more tool stands arranged one behind the other by exchanging one tool frame for another after uncoupling, without any time have to be postponed beforehand so that unproductive downtimes that occur during the changeover are reduced to a minimum.

Für eine konstruktiv einfache Lösung und gleichzeitig präzise Arbeitsweise ist es vorteilhaft, wenn der Getriebeblock und das Kupplungsgerüst od.dgl. auf einem gemeinsamen Getriebeträger befestigt sind, welcher mittels eines Antriebes in Führungen, z.B. Gleitführungen, quer zur Vorschubrichtung des Werkstückes, insbesondere rechtwinklig zur Vorschubrichtung, maschinell verstellbar ist. Dadurch bleibt der Abstand zwischen Getriebeblock und Kupplung unverändert und es muß nur die sich ändernde Höhenlage vor allem der oberen Kupplung an dem Kupplungsgerüst oder -träger durch die zwischen Getriebeblock und Kupplungsgerüst befindlichen Gelenkwellen ausgeglichen werden. Für die Querverschiebung genügt dabei jeweils ein einziger Antrieb. Beispielsweise kann dabei zum Verschieben des Getriebeblockes mit dem Kupplungsgerüst od.dgl. eine motorgetriebene Spindel vorgesehen sein, wodurch auch möglich ist, beim Einkuppeln zunächst ein erstes Teil des Verschiebeweges durchzuführen, bevor dann die Höhenanpassung der im Kupplungsgrüst oder am Kupplungsträger befindlichen Kupplungshälfte auf eine eventuell durch den Werkzeugwechsel sich auf anderer Höhe befindliche Kupplungshälfte an den Umformrollen erfolgt, wonach dann die endgültige Verschiebebewegung des Getriebeblockes und des Kupplungsgerüstes od.dgl. in Arbeitsstellung durchführbar ist. Diese Verschiebebewegung des Getriebeblockes kann also in zwei Schritten erfolgen.For a structurally simple solution and at the same time precise mode of operation, it is advantageous if the gear block and the coupling frame or the like. are fastened to a common gear carrier, which is mechanically adjustable by means of a drive in guides, for example sliding guides, transversely to the feed direction of the workpiece, in particular at right angles to the feed direction. As a result, the distance between the gear block and clutch remains unchanged and it is only necessary to compensate for the changing altitude, especially of the upper clutch on the coupling frame or carrier, by means of the cardan shafts located between the gear block and coupling frame. A single drive is sufficient for the transverse displacement. For example, the like can be used to move the gear block with the coupling frame. a motor-driven spindle can be provided, which also makes it possible to first carry out a first part of the displacement path when engaging, before then adjusting the height of those located in the coupling structure or on the coupling carrier Coupling half is carried out on a coupling half on the forming rollers which may be at a different height due to the tool change, after which the final displacement movement of the gear block and the coupling frame or the like. is feasible in the working position. This shifting movement of the gear block can therefore take place in two steps.

Eine abgewandelte Ausführungsform, bei welcher die bewegbaren Massen vermindert sind, kann darin bestehen, daß der Getriebeblock und das Kupplungsgerüst od.dgl. jeweils auf einem eigenen Träger oder Lager befestigt sind und nur das Kupplungsgerüst od.dgl. oder der das Kupplungsgerüst od.dgl. tragende Träger mittels eines Antriebes, z.B. einer motorisch getriebenen Spindel, vorzugsweise in Führungen, quer zur Vorschubrichtung des Werkstückes maschinell verstellbar ist. Dies ist problemlos möglich, weil die Gelenkwellen in bekannter Weise in ihrer Länge durch Auseinanderziehen und Zusammenschieben verstellbar sind, was im übrigen auch die Höhenverstellung der einzelnen Kupplungen begünstigt.A modified embodiment in which the movable masses are reduced may consist in the fact that the gear block and the coupling frame or the like. are each attached to their own support or bearing and only the coupling frame or the like. or the like, the coupling frame. load-bearing beams by means of a drive, e.g. a motor-driven spindle, preferably in guides, is mechanically adjustable transversely to the feed direction of the workpiece. This is possible without any problems because the length of the cardan shafts can be adjusted in a known manner by pulling them apart and pushing them together, which also favors the height adjustment of the individual couplings.

Eine besonders zweckmäßige, das vollautomatische Anpassen der Höhenlage der Kupplungshälften erleichternde Ausgestaltung der Erfindung kann darin bestehen, daß als Fühler oder Sensor an dem Kupplungsgerüst od.dgl. oder gegebenenfalls an dem Werkzeuggerüst ein vorzugsweise parallel zur Achse der Kupplungswelle orientierter Arm vorgesehen ist, der am Ende der Höhenverstellung mit einem Gegenanschlag die Kupplungshälfte in ihrer Einkuppelstellung zur Gegen-Kupplungshälfte fixiert. Es kann also auf rein mechanischem Weg durch einen Anschlagarm und einen Gegenanschlag bewirkt werden, daß die Höhenverstellung der einen Kupplungshälfte im richtigen Augenblick beendet wird, wenn nämlich die Kupplungshälften zum Einkuppeln in übereinstimmender Position angelangt sind.A particularly expedient, the fully automatic adjustment of the height of the coupling halves facilitating embodiment of the invention can consist in that as a sensor or sensor on the coupling frame or the like. or, if appropriate, an arm, preferably oriented parallel to the axis of the coupling shaft, is provided on the tool frame, which fixes the coupling half in its coupling position to the counter-coupling half at the end of the height adjustment with a counter stop. It can thus be effected in a purely mechanical way by means of a stop arm and a counterstop that the height adjustment of the one coupling half is ended at the right moment, namely when the coupling halves have arrived in the same position for engaging.

Eine vorteilhafte Ausgestaltung kann dabei darin bestehen, daß der Gegenanschlag für den Arm eine der Kupplungshälften ist. Ist beispielsweise der Anschlagarm Kupplungsgerüst od.dgl. befestigt, kann die an dem Werkzeuggerüst befindliche Kupplungshälfte sein Gegenanschlag sein.An advantageous embodiment can consist in that the counter stop for the arm is one of the coupling halves. For example, the stop arm coupling frame or the like. attached, the coupling half located on the tool frame can be its counter-stop.

Als Antrieb für die Höhenverstellung der Kupplung kann ein Arbeitszylinder, insbesondere ein pneumatischer Zylinder, oder ein Stellmotor vorgesehen sein. Derartige Antriebsmittel können nämlich durch einen mechanischen Anschlag auch dann stillgesetzt werden, wenn sie noch unter Druck oder Strom stehen, so daß kein großer Steueraufwand und dergleichen für das automatische Ausrichten der beiden Kupplungshälften aufeinander in ihrer Kupplungsposition erforderlich ist.A working cylinder, in particular a pneumatic cylinder, or a servomotor can be provided as the drive for the height adjustment of the coupling. Such drive means can namely be stopped by a mechanical stop even when they are still under pressure or current, so that no great control effort and the like is required for the automatic alignment of the two coupling halves to one another in their coupling position.

Es sei noch erwähnt, daß sowohl die obere als auch die untere Lagerung der Gelenkwellen an dem Kupplungsgerüst od.dgl. maschinell in der Höhe verstellbar sein kann, so daß die Kupplungen für ein Umformrollen-Paar an dessen Arbeitswellen angepaßt werden können.It should also be mentioned that both the upper and the lower bearing of the drive shafts on the coupling frame or the like. can be mechanically adjustable in height so that the couplings for a pair of forming rollers can be adapted to the working shafts.

Eine der Kupplungshälften, insbesondere die von dem verschiebbaren Kupplungsgerüst od.dgl. getragene Kupplungshälfte, kann ihrerseits - gegenüber dem Kupplungsgerüst o.dgl. - axial gegen eine Rückstellkraft verschiebbar sein. Dies gilt insbesondere für solche Kupplungen, deren Hälften formschlüssig ineinandergreifen. Passen die beiden Hälften beim Einkuppeln noch nicht ineinander, weil sie in Drehrichtung gegeneinander versetzt sind, kann also die eine Kupplungshälfte zunächst ausweichen. Es genügt dann, den Antrieb kurz anlaufen zu lassen, um die zueinander passenden Teile, beispielsweise Kupplungsstifte und Kupplungslochungen od.dgl., in Übereinstimmung zu bringen, so daß die Rückstellkraft dann die Einrückbewegung der verschiebbaren Kupplungshälfte beendet.One of the coupling halves, in particular that of the sliding coupling frame or the like. worn coupling half, in turn - or the like - compared to the coupling frame. - Be axially displaceable against a restoring force. This applies in particular to couplings whose halves interlock positively. If the two halves do not yet fit into each other when engaging, because they are offset in the direction of rotation, one half of the coupling can initially dodge. It is then sufficient to briefly start the drive in order to bring the matching parts, for example coupling pins and coupling perforations or the like, into alignment, so that the restoring force then ends the engagement movement of the displaceable coupling half.

Dabei kann die Rückstellkraft für die vorzugsweise an dem Kupplungsgerüst od.dgl. befindlichen Kupplungshälften durch Druckfedern erzeugt sein und beide an dem Kupplungsgerüst befindlichen Kupplungshälften können axial gegen Federkraft verschiebbar sein.The restoring force for the preferably on the coupling frame or the like. located coupling halves can be generated by compression springs and both coupling halves located on the coupling frame can be axially displaceable against spring force.

Der vollautomastische Werkzeugwechsel und insbesondere auch die vollautomatische Wiedereinkupplung können dadurch gefördert und verbessert werden, daß Sensoren zum Überwachen des Einkuppelvorganges vorgesehen sind, die den Antrieb bis zum Ende des Kupplungsvorganges sperren. Dadurch wird sichergestellt, daß der Antrieb der Profiliermaschine und der Umformrollen erst wieder anlaufen kann, wenn wirklich alle Kupplungen eingerückt und funktionsbereit sind. Weitere Ausgestaltungen der Erfindung sind Gegenstand der Ansprüche 11 und 12.The fully automatic tool change and in particular also the fully automatic re-coupling can be promoted and improved in that sensors are provided for monitoring the coupling process, which block the drive until the end of the coupling process. This ensures that the drive of the profiling machine and the forming rollers can only start again when all the couplings are really engaged and ready for operation. Further embodiments of the invention are the subject of claims 11 and 12.

Bei Kombination einzelner oder mehrerer der vorbeschriebenen Merkmale und Maßnahmen ergibt sich eine Profiliermaschine der eingangs genannten Art, bei der ein Umformrollen-Paar oder auch mehrere vollautomatisch ausgetauscht werden können, wobei auch Sorge dafür getragen ist, daß die jeweils erforderliche Kupplungsbewegung vollautomatisch erfolgen kann. Dennoch ist die gesamte Konstruktion einfach und somit vergleichsweise preiswert.Combining one or more of the features and measures described above results in a profiling machine of the type mentioned at the outset, in which one or more forming rolls can be exchanged fully automatically, care also being taken to ensure that the coupling movement required in each case can take place fully automatically. Nevertheless, the entire construction is simple and therefore comparatively inexpensive.

Eine im ganzen mit 1 bezeichnete Profiliermaschine hat in bekannter Weise entweder ein oder in Vorschubrichtung eines Werkstückes hintereinander mehrere Umformrollen-Paare 2, die in bekannter Weise aus zueinanderpassenden Umformrollen 3 u.4 gebildet sind, deren Außenkonturen in ihrem Arbeitsbereich den jeweils an ihnen zu bildenden Querschnitt des Werkstückes erzeugen. Diese Umformrollen-Paare 2 sind mittels Arbeitswellen 5 jeweils in einem Werkzeuggerüst 6 gelagert, welches an einem lösbar an der Profiliermaschine 1 bzw. deren Untergestell 7 befestigten Werkzeugträger 8 aufgebaut ist, wobei eine nicht näher dargestellte Hebeeinrichtung zum Abheben und Austauschen dieser Werkzeuggerüste 6 vorgesehen ist. Die Werkzeugträger 8 sind dabei im Ausführungsbeispiel am Maschinenuntergestell 7 durch Zentrierbolzen 9, die zu entsprechenden Lochungen passen, zentriert. Es könnten aber auch andere Positionier- und/oder Zentriereinrichtungen vorgesehen sein.A profiling machine, designated as a whole by 1, has, in a known manner, either one or a plurality of pairs of forming rollers 2 in the feed direction of a workpiece, which pairs are formed in a known manner from matching forming rollers 3 and 4, the outer contours of which in their working area are to be formed on them Generate cross-section of the workpiece. These forming roller pairs 2 are by means of Working shafts 5 are each mounted in a tool frame 6, which is constructed on a tool carrier 8 which is detachably fastened to the profiling machine 1 or its base frame 7, a lifting device (not shown in more detail) for lifting and exchanging these tool frames 6 being provided. In the exemplary embodiment, the tool carriers 8 are centered on the machine base frame 7 by means of centering bolts 9 which match the corresponding perforations. However, other positioning and / or centering devices could also be provided.

Das Werkzeuggerüst 6 besteht im Ausführungsbeispiel aus einem unteren Lagergehäuse 10, darin beidseits eingelassenen Säulen 11 und oberen Lagergehäusen 12 sowie einem Joch 13, welches jeweils eine Stellschraube 13a trägt, die die Stellung des jeweiligen oberen Lagergehäuses 12 bestimmt. Die Lagergehäuse 10 u.12 enthalten die Lager für die Arbeitswellen 5 der unteren und oberen Umformrollen 4 u.3. Der Abstand zwischen unterer und oberer Arbeitswelle 5 und damit die Lage der oberen Lagergehäuse 12 wird durch den Durchmesser der oberen Umformrolle 3 bestimmt und ist von Umformrollen-Paar zu Umformrollen-Paar verschieden.In the exemplary embodiment, the tool frame 6 consists of a lower bearing housing 10, columns 11 embedded therein on both sides and upper bearing housings 12 and a yoke 13, each of which carries an adjusting screw 13a which determines the position of the respective upper bearing housing 12. The bearing housings 10 and 12 contain the bearings for the working shafts 5 of the lower and upper forming rollers 4 and 3. The distance between the lower and upper working shaft 5 and thus the position of the upper bearing housing 12 is determined by the diameter of the upper forming roller 3 and is different from pair of forming rollers to pair of forming rollers.

Die Arbeitswellen 5 tragen darüber hinaus an ihren den Umformrollen 3 u.4 abgewandten Enden jeweils Gegen-Kupplungshälften 14 von Kupplungen 15.The working shafts 5 also carry counter-coupling halves 14 of couplings 15 at their ends facing away from the forming rollers 3 and 4.

Neben den Werkzeuggerüsten 6 befindet sich ein Antrieb mit einem Getriebeblock 16 und zwischen diesem und den ihm zugewandten Enden der Arbeitswellen 5 erkennt man Gelenkwellen 17 und die Kupplungen 15 zum Lösen der Antriebsverbindung der Umformrollen 3 u.4 für deren Auswechselung.In addition to the tool stands 6 there is a drive with a gear block 16 and between this and the ends of the working shafts 5 facing it, drive shafts 17 and the couplings 15 for releasing the drive connection of the forming rolls 3 and 4 for their replacement can be seen.

Dabei ist zwischen dem jeweiligen Werkzeuggerüst 6 und dem zugehörigen Getriebeblock 16 ein Kupplungsgerüst 18 vorgesehen, auf dessen dem Getriebeblock 16 zugewandter Seite die Gelenkwellen 17 und auf dessen dem Werkzeuggerüst 6 zugewandter Seite die lösbaren Kupplungen 15 für die Arbeitswellen 5 angeordnet sind. Statt des Kupplungsgerüstes 18 könnte auch ein andersartiger Kupplungsträger oder -halter vorgesehen sein.A coupling frame 18 is provided between the respective tool frame 6 and the associated gear block 16, on the side facing the gear block 16 the drive shafts 17 and on the side facing the tool frame 6 the releasable couplings 15 for the working shafts 5 are arranged. Instead of the coupling frame 18, a different type of coupling carrier or holder could also be provided.

Der Getriebeblock 16 ist nun zusammen mit dem Kupplungsgerüst 18 quer zur Vorschubrichtung des Werkstückes und quer zur Arbeitsrichtung der Umformrollen 3 u.4 zum Lösen der Kupplungen 15 von dem Werkzeuggerüst 6 weg in Richtung a des Doppelpfeiles Pf 1 verschiebbar.The gear block 16 can now be moved together with the coupling frame 18 transversely to the direction of advance of the workpiece and transversely to the working direction of the forming rollers 3 and 4 to release the couplings 15 away from the tool frame 6 in the direction a of the double arrow Pf 1.

Die Lagerung der oberen Gelenkwelle 17 an dem Kupplungsgerüst 18 ist maschinell in der Höhe verstellbar, so daß auch die ihr zugeordnete Kupplungshälfte 19 der Kupplung 15 höhenverstellbar ist. Im Ausführungsbeispiel ist an dem Kupplungsgerüst 18 ein noch näher zu beschreibender Fühler zum automatischen und selbsttätigen Einstellen auf die jeweilige Höhe der Gegenkupplung bzw. Kupplungshälfte 14 der zugehörigen Arbeitswelle 5 vorgesehen. Der Verschiebeantrieb für den Getriebeblock 16 mit dem Kupplungsgerüst 18 ist nun derart angesteuert, daß die Verschiebebewegung oder ihr letztes Teilstück in Richtung b des Doppelpfeiles Pf 1 zum Einkuppeln erst nach der Höheneinstellung der Kupplung an dem Kupplungsgerüst erfolgt. Entweder könnte bei genügend langem Fühler zuerst die Höheneinstellung und dann die vollständige Verschiebebewegung des Getriebeblockes 16 erfolgen.The height of the mounting of the upper propeller shaft 17 on the coupling frame 18 can be adjusted mechanically, so that the coupling half 19 of the coupling 15 assigned to it can also be adjusted in height. In the exemplary embodiment, a sensor to be described in more detail for automatic and automatic adjustment to the respective height of the mating coupling or coupling half 14 of the associated working shaft 5 is provided on the coupling frame 18. The shift drive for the gear block 16 with the coupling frame 18 is now controlled such that the shifting movement or its last section in direction b of the double arrow Pf 1 for coupling takes place only after the height adjustment of the coupling on the coupling frame. With a sufficiently long sensor, either the height adjustment and then the complete displacement movement of the gear block 16 could take place.

Im Ausführungsbeispiel ist jedoch vorgesehen, daß die Antriebsgruppe bestehend aus Getriebeblock 16 und Kupplungsgerüst 18 in Richtung b des Doppelpfeiles Pf 1 bis zu dem Punkt b1 verschoben, dort die Verschiebebewegung unterbrochen und das obere Lagergehäuse 18a des Kupplungsgerüstes 18 in seiner Höhenlage verstellt wird, bis diese vertikale Verstellbewegung durch den noch näher zu beschreibenden Fühler begrenzt und beendet wird. Liegen dann die Kupplungshälften 19 u.14 auf übereinstimmender Höhe, kann das weitere Verschieben der Antriebsgruppe von b1 nach b erfolgen, um das Einrücken der Kupplung zu beenden.In the exemplary embodiment, however, it is provided that the drive group consisting of gear block 16 and coupling frame 18 is shifted in the direction b of the double arrow Pf 1 to point b1, where the shifting movement is interrupted and the upper bearing housing 18a of the coupling frame 18 is adjusted in its altitude until this vertical adjustment movement is limited and ended by the sensor, which will be described in more detail. If the coupling halves 19 and 14 are at the same height, the drive group can be shifted further from b1 to b in order to end the engagement of the coupling.

Der Getriebeblock 16 und das Kupplungsgerüst 18 sind dabei auf einem gemeinsamen Getriebeträger 20 befestigt, welcher mittels eines Antriebes, im Ausführungsbeispiel einer motorgetriebenen Spindel 21, in oder an Führungen 22 quer zur Vorschubrichtung des Werkstückes maschinell verstellbar ist. Den Antriebsmotor 23 für die Spindel 21 erkennt man in Fig. 1.The gear block 16 and the coupling frame 18 are fastened on a common gear carrier 20, which is mechanically adjustable by means of a drive, in the exemplary embodiment of a motor-driven spindle 21, in or on guides 22 transversely to the feed direction of the workpiece. The drive motor 23 for the spindle 21 can be seen in FIG. 1.

Als Fühler oder Sensor zum Einstellen der Höhe der oberen Kupplung und ihrer am Kupplungsgerüst 18 befindlichen Kupplungshälfte 19 ist im Ausführungsbeispiel an dem Kupplungsgerüst 18 ein parallel zur Achse der Kupplungswelle 24 orientierter Arm 25 vorgesehen, der aber auch umgekehrt an dem Werkzeuggerüst 6 sein könnte, und der zusammen mit einem Gegenanschlag die Höhenverstellung der beiden Kupplungshälften in ihrer Kupplungsstellung beendet.As a sensor or sensor for adjusting the height of the upper coupling and its coupling half 19 located on the coupling frame 18, an arm 25 oriented parallel to the axis of the coupling shaft 24 is provided in the exemplary embodiment on the coupling frame 18, but could also be reversed on the tool frame 6, and which, together with a counterstop, ends the height adjustment of the two coupling halves in their coupling position.

Man erkennt in den Figuren 1 u.2 deutlich, daß die Höhenverstellung der Kupplungshälfte 19 die entsprechende Höhenverstellung dieses Armes 25 bedeutet, bis dieser an seinem Gegenanschlag, im Ausführungsbeispiel der Kupplungshälfte 14, zur Anlage kommt. Dies stellt eine sehr einfache Höhenanpassung der beiden Kupplungshälften 14 u.19 aufeinander dar, die dennoch vollautomatisch erfolgen kann.It can be clearly seen in FIGS. 1 and 2 that the height adjustment of the coupling half 19 means the corresponding height adjustment of this arm 25 until it comes to rest on its counter-stop, in the exemplary embodiment of the coupling half 14. This represents a very simple height adjustment of the two coupling halves 14 and 19 to one another, which can nevertheless take place fully automatically.

Zur Höhenverstellung der oberen Kupplungshälfte 19 ist dabei ein vorzugsweise pneumatischer Arbeitszylinder 26 vorgesehen, jedoch könnte dies auch durch einen Stellmotor bewerkstelligt werden.A preferably pneumatic working cylinder 26 is provided for height adjustment of the upper coupling half 19, but this could also be accomplished by a servomotor.

In Fig. 2 erkennt man, daß die eine Kupplungshälfte, im Ausführungsbeispiel die an der Arbeitswelle 5 befindliche Kupplungshälfte 14, Lochungen 27 und die damit in Wirkverbindung tretende andere Kupplungshälfte, in diesem Falle also die Kupplungshälfte 19 in diese Lochungen 27 passende Kupplungsstifte 28 aufweist, die an ihrem Ende etwas konisch zulaufen, um den Kupplungsvorgang zu vereinfachen. Dennoch könnte es passieren, daß die Lochungen 27 und die Kupplungsstifte 28 beim Einkuppeln in Drehrichtung derart gegeneinander versetzt sind, daß der Kupplungsvorgang zunächst nicht erfolgt. Deshalb ist vorgesehen, daß eine der Kupplungshälften, in diesem Falle die von dem Kupplungsgerüst 18 getragene Kupplungshälfte 19 axial gegen eine Rückstellkraft verschiebbar ist, wobei die Rückstellkraft für die axial verstellbaren Kupplungshälfte 19 im Ausführungsbeispiel jeweils durch eine Druckfeder 29 erzeugt ist. In Fig. 2 erkennt man, daß beide Kupplungshälften 19 des Kupplungsgerüstes 18 axial gegen die Kraft einer solchen Druckfeder 29 ausweichen können, wenn bei der Durchführung der Kupplungsbewegung die Kupplungsstifte 28 nicht in die Lochungen 27 treffen, wobei dieser Fall in der Zeichnung an der unteren Kupplung dargestellt ist.In Fig. 2 it can be seen that the one coupling half, in the exemplary embodiment the coupling half 14 located on the working shaft 5, perforations 27 and the other coupling half coming into operative connection therewith, in this case the coupling half 19 having coupling pins 28 fitting into these perforations 27, which taper somewhat at the end to simplify the coupling process. Nevertheless, it could happen that the perforations 27 and the coupling pins 28 are offset against one another in the direction of rotation when engaging in such a way that the coupling process does not initially take place. It is therefore provided that one of the coupling halves, in this case the coupling half 19 carried by the coupling frame 18, is axially displaceable against a restoring force, the restoring force for the axially adjustable coupling half 19 each being generated in the exemplary embodiment by a compression spring 29. In Fig. 2 it can be seen that both coupling halves 19 of the coupling frame 18 can dodge axially against the force of such a compression spring 29 if the coupling pins 28 do not hit the holes 27 when performing the coupling movement, this case in the drawing on the lower Coupling is shown.

Dabei können nicht näher dargestellte Sensoren zum Überwachen des Einkuppelvorganges vorgesehen sein, die den Antrieb für den Getriebeblock 16 so lange sperren, bis der Kupplungsvorgang beendet ist. Sind dabei die Stifte 28 gegenüber den Lochungen 27 etwas versetzt, kann eine kurze Drehung des Antriebes erfolgen, bis die Stifte in die Lochungen eintreten können.In this case, sensors (not shown in more detail) can be provided for monitoring the engagement process, which block the drive for the transmission block 16 until the coupling process has ended. If the pins 28 are somewhat offset relative to the perforations 27, the drive can be briefly rotated until the pins can enter the perforations.

Der Wechsel der Umformrollen-Paare kann also bei dieser Profiliermaschine 1 vollautomatisch auf folgende Weise geschehen:
Die auf dem Getriebeträger 20 befindliche Antriebsgruppe aus Getriebeblock 16 und Kupplungsgerüst 18 wird mittels der durch den Motor 23 angetriebenen Spindel 21 auf den Führungen 22 gemäß dem Doppelpfeil Pf 1 in Richtung a bewegt. Dadurch werden die Kupplungsstifte 28 aus den Lochungen 27 der Kupplungshälften 14 herausgezogen, so daß der das Werkzeuggerüst 6 tragende Werkzeugträger 8 mittels einer Hebeeinrichtung abgehoben werden kann. Diese Hebeeinrichtung kann mit Zugriff auf ein Werkzeugmagazin versehen sein, in dem das komplette Werkzeuggerüst 6 mit Werkzeugträger 8 abgelegt werden kann. Dieselbe Hebeeinrichtung kann demselben Werkzeugmagazin ein anderes komplettes Werkzeug entnehmen und auf das Untergestell der Profiliermaschine 1 aufsetzen, wobei die Positionierung und Zentrierung durch die Zentrierbolzen 9 erfolgt.
The changing of the forming roller pairs can therefore take place fully automatically in this profiling machine 1 in the following way:
The drive group comprising the transmission block 16 and the coupling frame 18 located on the transmission carrier 20 is moved in the direction a by means of the spindle 21 driven by the motor 23 on the guides 22 according to the double arrow Pf 1. As a result, the coupling pins 28 are pulled out of the perforations 27 in the coupling halves 14 so that the tool carrier 8 carrying the tool frame 6 can be lifted off by means of a lifting device. This lifting device can be provided with access to a tool magazine in which the complete tool frame 6 with tool carrier 8 can be stored. The same lifting device can take another complete tool from the same tool magazine and place it on the base of the profiling machine 1, the positioning and centering being carried out by the centering bolts 9.

Danach werden die oberen Kupplungshälften 19 bzw. Kupplungswellen 24 über ihre Lagergehäuse mittels Arbeitszylinder 26 in vertikaler Richtung nach unten bewegt, bis das obere Lagergehäuse 18a auf dem unteren Lagergehäuse 18b aufliegt.Thereafter, the upper coupling halves 19 or coupling shafts 24 are moved vertically downward via their bearing housings by means of working cylinders 26 until the upper bearing housing 18a rests on the lower bearing housing 18b.

Zum Zusammenkuppeln fährt nun der Getriebeträger 20 mit dem Getriebeblock 16 und dem Kupplungsgerüst 18 in horizontaler Richtung gemäß dem Doppelpfeil Pf 1 in Richtung b. Bedingt durch die von Umformrollen-Paar zu Umformrollen-Paar unterschiedlichen Durchmesser der Umformrollen 3 u.4 verändert sich auch die Lage der oberen Arbeitswelle 5 und damit der oberen Kupplungshälfte 14 bei jedem ausgetauschten Umformrollen-Paar. Damit die Stifte 28 der Kupplungshälfte 19 in die Lochungen 27 der Kupplungshälfte 14 eingeführt werden können, muß die Höhenlage dieser Kupplungshälften 14 u.19 aufeinander angepaßt werden. Dies erfogt, indem die Zustellung des Getriebeträgers 20 in Richtung b bei b1, also nach einem Teil der Wegstrecke, unterbrochen und dann das obere Lagergehäuse 18a des Kupplungsgerüstes 18 mittels des Zylinders 26 nach oben angehoben wird.For coupling together, the gear carrier 20 now moves with the gear block 16 and the coupling frame 18 in the horizontal direction according to the double arrow Pf 1 in direction b. Due to the different diameters of the forming rollers 3 and 4 from the forming roller pair to the forming roller pair, the position of the upper working shaft 5 and thus the upper coupling half 14 also changes with each exchanged forming roller pair. So that the pins 28 of the coupling half 19 can be inserted into the holes 27 of the coupling half 14, the height of these coupling halves 14 and 19 must be adapted to one another. This is done by interrupting the infeed of the gear carrier 20 in direction b at b1, that is to say after part of the distance, and then lifting the upper bearing housing 18a of the coupling frame 18 upwards by means of the cylinder 26.

Diese Hubbewegung wird durch den Justierarm 25 automatisch und selbsttätig begrenzt. Liegt nämlich dieser Arm 25 an der als Gegenanschlag dienenden Kupplungshälfte 14 an, ist die Position erreicht, in welcher die Stifte 28 der Kupplungshälfte 19 in die Lochungen 27 der Kupplungshälfte 14 hineingefahren werden können, was durch eine weitere Verschiebung der Antriebsgruppe in Richtung des Doppelpfeiles Pf 1 von b1 nach b erfolgt.This stroke movement is automatically and automatically limited by the adjusting arm 25. If this arm 25 is in contact with the coupling half 14 serving as a counterstop, the position is reached in which the pins 28 of the coupling half 19 can be moved into the holes 27 in the coupling half 14, which is caused by a further displacement of the drive group in the direction of the double arrow Pf 1 from b1 to b.

In bereits beschriebener Weise kann dabei die jeweilige Kupplungshälfte 19 in axialer Richtung gegen die Kraft der Feder 29 axial ausweichen, falls die Stifte 28 nicht genau auf die Lochungen 27 treffen. Durch eine leichte Rotationsbewegung der Kupplungshälften 19 können die Stifte in Übereinstimmung mit den Lochungen gebracht und dann durch die Federn eingerückt werden. Damit ist der Vorgang des Werkzeugwechsels vollautomatisch und sehr schnell abgeschlossen und die Maschine 1 wieder produktionsbereit.In the manner already described, the respective coupling half 19 can dodge axially in the axial direction against the force of the spring 29 if the pins 28 do not exactly meet the perforations 27. With a slight rotational movement of the coupling halves 19, the pins can be brought into line with the perforations and then inserted by the springs. This completes the tool change process fully automatically and very quickly and machine 1 is ready for production again.

Eine Profiliermaschine 1 mit einem oder mehreren in Vorschubrichtung eines Werkstückes hintereinander angeordneten Umformrollen-Paaren 2, die in Werkzeuggerüsten 6 gegert sind, hat zwischen einem Getriebeblock 16 und den diesem zugewandten Enden der Arbeitswellen 5 der Umformrollen 3 u.4 Gelenkwellen 17 und Kupplungen 15 zum Lösen der Antriebsverbindung der Umformrollen 3 u.4, wenn diese ausgewechselt werden sollen. Dabei ist zwischen dem jeweiligen Werkzeuggerüst 6 und dem zugehörigen Getriebeblock 16 ein Kupplungsgerüst 18 vorgesehen, auf dessen dem Getriebeblock 16 zugewandter Seite die Gelenkwellen 17 und auf dessen dem Werkzeuggerüst 6 zugewandter Seite die lösbaren Kupplungen 15 für die Arbeitswellen 5 angeordnet sind. Der Getriebeblock 16 kann zusammen mit dem Kupplungsgerüst 18 quer zur Vorschubrichtung des Werkstückes und quer zur Arbeitsrichtung der Umformrollen 3 u.4 zum Lösen der Kupplungen 15 von dem Werkzeuggerüst 6 wegverschoben werden. Die Lagerung zumindest der oberen Gelenkwelle 17 kann an dem Kupplungsgerüst 18 maschinell in der Höhe verstellt werden und entweder am Kupplungsgerüst 18 oder am Werkzeuggerüst 6 ist ein Fühler, Sensor od.dgl. Schaltelement zum automatischen und selbsttätigen Einstellen auf die jeweilige Höhe der Gegenkupplung 14 vorgesehen. Der Verschiebeantrieb für den Getriebeblock 16 mit dem Kupplungsgerüst 18 ist derart angesteuert, daß die Verschiebebewegung oder ihr letztes Teilstück zum Einkuppeln erst nach der Höheneinstellung der Kupplungshälften aufeinander an dem Kupplungsgerüst erfolgt. Es sei noch erwähnt, daß statt des von unten nach oben gegen den Gegenanschlag, im Ausführungsbeispiel die Kupplungshälfte 14, verschiebbaren Armes 25 dieser auch umgekehrt aus einer oberen Ausgangslage des Lagergehäuses 18a nach unten verstellbar sein könnte.A profiling machine 1 with one or more pairs of forming rollers 2 arranged one behind the other in the direction of feed of a workpiece, which are parted in tool stands 6, has between a gear block 16 and the ends of the working shafts 5 of the shaping rollers 3 and 4 facing them 17 and couplings 15 for Loosen the drive connection of the forming rollers 3 and 4 if they are to be replaced. A coupling frame 18 is provided between the respective tool frame 6 and the associated gear block 16, on the side facing the gear block 16 the drive shafts 17 and on the side facing the tool frame 6 the releasable couplings 15 for the working shafts 5 are arranged. The gear block 16 can, together with the coupling frame 18, transversely to the feed direction of the workpiece and transversely to the working direction of the forming rollers 3 and 4 for releasing the couplings 15 be moved away from the tool frame 6. The mounting of at least the upper propeller shaft 17 can be mechanically adjusted in height on the coupling frame 18 and a sensor, sensor or the like is either on the coupling frame 18 or on the tool frame 6. Switching element for automatic and automatic adjustment to the respective height of the counter clutch 14 is provided. The displacement drive for the gear block 16 with the coupling frame 18 is controlled in such a way that the displacement movement or its last part for engaging takes place only after the height adjustment of the coupling halves on the coupling frame. It should also be mentioned that instead of the arm 25, which is displaceable from below upwards against the counter-stop, in the exemplary embodiment the coupling half 14, the latter could also be reversely adjustable downward from an upper starting position of the bearing housing 18a.

In beiden Fällen ist der Arm 25 an dem höhenverstellbaren Lagergehäuse 18a befestigt und der Gegenanschlag in seinem Verstellweg angeordnet. Wenn er sich an dem Walzgerüst befindet, kann die Kupplungshälfte 19 bei der aus einer unteren oder oberen Ausgangslage erfolgenden Verstellung gegen den Arm 25 zur Anlage kommen, wenn die Höhenlagen der Kupplungshälften übereinstimmen.In both cases, the arm 25 is attached to the height-adjustable bearing housing 18a and the counter-stop is arranged in its adjustment path. If it is on the roll stand, the coupling half 19 can come to rest against the arm 25 when the adjustment takes place from a lower or upper starting position if the height positions of the coupling halves match.

In Fig. 3 ist eine etwas abgewandelte Ausführungsform einer Profiliermaschine 1 dargestellt, bei welcher alle wesentlichen Teile und ihre Funktionen übereinstimmen und die deshalb in der Zeichnung entsprechend gekennzeichnet sind, aber nicht mehr im einzelnen beschrieben werden.3 shows a somewhat modified embodiment of a profiling machine 1, in which all the essential parts and their functions correspond and which are therefore marked accordingly in the drawing, but are no longer described in detail.

Im Unterschied zur Ausführungsform nach Fig. 1 und 2 ist jedoch bei dieser Ausführungsform nach Fig. 3 vorgesehen, daß der Getriebeblock 16 und das Kupplungsgerüst 18 jeweils auf einem eigenen Träger oder Lager 20a und 20b befestigt sind und nur das Kupplungsgerüst 18 oder der das Kupplungsgerüst 18 tragende Träger 20b mittels eines Antriebes, im Ausführungsbeispiel einer motorisch betriebenen Spindel 30 in Führungen 31 quer zur Vorschubrichtung des Werkstückes und in axialer Erstreckungsrichtung der Arbeitswellen 5 verstellbar ist. Da die Gelenkwellen 17 in ihrer Länge durch Zusammenschieben oder Auseinanderziehen stufenlos und selbsttätig verstellbar und auch an unterschiedliche Höhenlagen der Kupplungen anpassbar sind, ist auch diese Verstellbewegung des Kupplungsgerüstes 18 unabhängig von dem Getriebeblock 16 problemlos möglich.In contrast to the embodiment according to FIGS. 1 and 2, however, it is provided in this embodiment according to FIG. 3 that the gear block 16 and the coupling frame 18 are each fastened on their own carrier or bearing 20a and 20b and only the coupling frame 18 or the carrier 20b carrying the coupling frame 18 can be adjusted by means of a drive, in the exemplary embodiment of a motor-driven spindle 30 in guides 31 transversely to the direction of advance of the workpiece and in the axial direction of extension of the working shafts 5. Since the length of the cardan shafts 17 is continuously and automatically adjustable by pushing or pulling them apart and can also be adapted to different heights of the couplings, this adjustment movement of the coupling frame 18 is also possible without any problems regardless of the gear block 16.

Schließlich sei noch erwähnt, daß in beiden Ausführungsbeispielen sowohl die obere Lagerung 18a als auch die untere Lagerung 18b der Gelenkwellen 17 an dem Kupplungsgerüst 18 maschinell in der Höhe verstellbar sein können, um beide Kupplungen 15 auf jeweils unterschiedliche Höhenlagen von Arbeitswellen 5 einstellen zu können. Dabei kann die Höhenverstellung der unteren Lagerung 18b in gleicher Weise wie die der oberen erfolgen.Finally, it should also be mentioned that in both exemplary embodiments, both the upper bearing 18a and the lower bearing 18b of the drive shafts 17 on the coupling frame 18 can be mechanically adjustable in height in order to be able to adjust both couplings 15 to different height positions of working shafts 5. The height of the lower bearing 18b can be adjusted in the same way as that of the upper one.
