Description

Die Erfindung betrifft eine Vorrichtung zum Austausch von Stütz- oder Treibrollen einer Stranggießanlage mit einer zwei einander gegenüberliegende Rollenbahnen aufweisenden Strangführung, wobei die Vorrichtung einen zwischen den Rollenbahnen zum An- und Abtransport einer Rolle von einer bzw. zu einer Lagerung in einer der Rollenbahnen bewegbaren Schlitten, der mit die Rollen aufnehmenden Rollensitzen ausgestattet ist und eine Einrichtung zum Bewegen einer Rolle von ihrer Lagerungsstelle zum Schlitten bzw. vom Schlitten zur Lagerungsstelle aufweist.The invention relates to a device for exchanging support or drive rollers of a continuous casting installation with a strand guide having two roller conveyors lying opposite one another, the device comprising a carriage which can be moved between the roller conveyors for transporting a roller to and from or for storage in one of the roller conveyors , which is equipped with the roller-receiving roller seats and has a device for moving a roller from its storage location to the carriage or from the carriage to the storage location.

Die Stütz- und Treibrollen stellen bei Stranggießanlagen, insbesondere bei Stahlstranggießanlagen, besonders hoch beanspruchte Maschinenteile dar. Ihre Gebrauchsdauer ist, verglichen mit anderen Maschinenteilen an Stranggießanlagen, verhältnismäßig gering. Aus diesem Grund müssen die Stütz- und Treibrollen im Zuge von Wartungsarbeiten des öfteren gegen neue oder überholte Rollen ausgetauscht werden. Kommt es zu einem Versagen von Stütz- oder Treibrollen, so sollen die schadhaften Rollen zur Vermeidung längerer Stillstandszeiten der Anlage binnen kürzester Zeit ersetzt werden.The support and drive rollers in machine parts, in particular in steel machine systems, represent particularly highly stressed machine parts. Their service life is relatively short compared to other machine parts in machine lines. For this reason, the support and drive rollers often have to be replaced with new or reconditioned rollers in the course of maintenance work. If support or drive rollers fail, the defective rollers should be replaced within a very short period of time to avoid long downtimes.

Aus der AT-PS 337 919 ist eine Vorrichtung der eingangs beschriebenen Art bekannt, wobei beispielsweise ein Rolleneinbau in die Stranggießanlage in der Weise vorgenommen wird, daß die einzubauende Rolle in einen Rollensitz des Schlittens eingelegt, mit dem Schlitten zwischen die Rollenbahnen transportiert und mittels einer am Schlitten oder an den Rollenbahnen seitlich befestigbaren Führung, an der ein mit dem jeweiligen Rollenende der einzubauenden Rolle in Eingriff bringbarer Mitnehmer geführt ist, in die Lagerung der Rollenbahn eingesetzt wird.From AT-PS 337 919 a device of the type described is known, for example, a roll installation in the continuous caster is carried out in such a way that the roll to be installed is placed in a roller seat of the slide, transported with the slide between the roller tracks and by means of a is guided on the carriage or to the roller tracks fastened laterally guide on which a olle end to the respective R of the roll to be incorporated in engagable driver, is inserted into the bearing of the roller conveyor.

Das Anbringen der seitlichen Verschiebeeinrichtungen bedingt einen zusätzlichen Zeitaufwand und es muß ein Bedienungsmann seitlich der Strangführung bis zur auszutauschenden Rolle einsteigen, um die Verschiebevorrichtung anzubringen. Dies ist wegen des geringen Platzes seitlich der Strangführung ein schwieriger Arbeitsvorgang.The attachment of the lateral shifting devices requires an additional expenditure of time and an operator has to climb into the side of the strand guide up to the role to be exchanged in order to attach the shifting device. This is a difficult operation because of the small space to the side of the strand guide.

Die Erfindung bezweckt die Vermeidung dieser Schwierigkeiten und stellt sich die Aufgabe, eine Vorrichtung der eingangs beschriebenen Art zu schaffen, mit der die Zeit, die für einen Rollenwechsel erforderlich ist, wesentlich verkürzt werden kann, bei der der Wechselvorgang insgesamt vereinfacht ist und mit der insbesondere der Platz seitlich der Strangführung zum Rollenwechseln nicht benötigt wird.The invention aims at avoiding these difficulties and has as its object to provide a device of the type described in the introduction with which the time required for a roll change can be substantially reduced, with which the change process is simplified overall and with which in particular the space to the side of the strand guide for changing rolls is not required.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Rollensitze an dem Schlitten quer zur Längsrichtung der Rollen beweglich angeordnet sind und mittels einer Stelleinrichtung aus einer im Schlitten zurückgezogenen Transportposition in eine aus dem Schlitten vorragende Eingriffsposition bewegbar sind. Zweckmäßig sind die Rollensitze an am Schlitten angelenkten Schwenkarmen befestigt.This object is achieved in that the roller seats are movably arranged on the carriage transversely to the longitudinal direction of the rollers and can be moved by means of an actuating device from a transport position retracted in the carriage into an engagement position protruding from the carriage. The roller seats are expediently fastened to swivel arms articulated on the slide.

Bei einem geringen Platzangebot zwischen den Rollenbahnen sind zweckmäßig die Rollensitze an am Schlitten angelenkten Schwenkarmen schwenkbar befestigt und mit einem Fortsatz versehen, der in zurückgezogener Transportposition des Rollensitzes an einem Anschlag des Schwenkhebels und in aus dem Schlitten vorragender Eingriffsposition des Rollensitzes an der der auszubauenden Rolle benachbarten Rolle anliegt.If there is little space between the roller conveyors, the roller seats are expediently pivotably attached to pivot arms which are articulated on the slide and provided with an extension which, in the retracted transport position of the roller seat, touches a stop of the pivot lever and in the engagement position of the roller seat projecting from the slide on the roller adjacent to the roller to be removed Role.

Eine bevorzugte Ausführungsform ist dadurch gekennzeichnet, daß die Rollensitze an am Schlitten angelenkten Schwenkarmen schwenkbar befestigt sind und jeweils mit einem Fortsatz versehen sind, der in Transportposition des Rollensitzes an einem Anschlag des Schlittens anliegt und daß jeweils an dem Schwenkarm eine Klinke schwenkbar befestigt ist, die einerseits mit einem ihrer Enden mit einem Ansatz am Fortsatz des Rollensitzes anliegt und mit ihrem anderen Ende an einem im Schlitten angeordneten Anschlag anliegt, wobei die Klinke den Rollensitz mit seiner die Rolle aufnehmenden öffnung stets zur Rolle hin gerichtet hält, wodurch die Vorrichtung auch bei ganz besonders eng einander gegenüberliegenden Rollenbahnen, in denen die Rollen ebenfalls eng benachbart angeordnet sind, verwendet werden kann.A preferred embodiment is characterized in that the roller seats are pivotally attached to swivel arms articulated on the sled and are each provided with an extension which bears against a stop of the sled in the transport position of the roller seat and that a pawl is pivotally attached to the swivel arm, which on the one hand, one end of it rests with a shoulder on the extension of the roller seat and, at the other end, it rests on a stop arranged in the slide, the pawl always holding the roller seat with its opening that receives the roller directed towards the roller, so that the device can also be used entirely roller conveyors lying particularly closely opposite one another, in which the rollers are also arranged closely adjacent, can be used.

Für den Austausch der an der oberen Rollenbahn liegenden Rollen ist es vorteilhaft, daß die Rollensitze als die Rollen umgreifende, elastisch verformbare federnde Klammern ausgebildet sind.For the exchange of the rollers lying on the upper roller conveyor, it is advantageous that the roller seats are designed as elastically deformable resilient clamps encompassing the rollers.

Nach einer weiteren bevorzugten Ausführungsform weisen die Rollensitze zwischen die Rollen der Rollenbahn einführbare, die Rollen hintergreifende, verschwenkbare Riegel auf, die um eine senkrecht zur Rollenbahn angeordnete Achse aus einer zu den Rollenachsen parallel liegenden Position in eine zu den Rollenachsen querliegende Position verschwexikbar sind, wodurch es möglich ist, die Rol-Jen der unteren Rollenbahn sicher zu erfassen und im Rollensitz festzuhalten. Zweckmäßig ist der Schwenkarm als Winkelhebel ausgebildet, an dessen einem Hebelsarm der Rollensitz montiert und an dessen anderem Hebelsarm ein am Schlitten angelenkter Druckmittelzylinder gelenkig be-. festigt ist.According to a further preferred embodiment, the roller seats have between the rollers of the roller conveyor feasible, behind the rollers, swiveling latches, which can be swiveled about an axis arranged perpendicular to the roller conveyor from a position parallel to the roller axes into a position transverse to the roller axes, whereby it is possible to securely lock the roller-Jen to the lower roller conveyor capture and hold in the role seat. The swivel arm is expediently designed as an angle lever, on one lever arm of which the roller seat is mounted and on the other lever arm a pressure medium cylinder articulated on the slide is articulated. is consolidated.

Die erfindungsgemäße Vorrichtung ist anhand der schematischen Zeichnung an drei Ausführungsbeispielen näher erläutert, wobei Fig. 1 einen Längsschnitt durch einen Teil einer schematisch dargestellten Strangführung darstellt, in der ein Schlitten gemäß einer ersten Ausführungsform zum Austauschen der an der Innen- bzw. Oberseite der Strangführung sitzenden Rollen dargestellt ist. Fig. 2 zeigt eine Ansicht des Schlittens teilweise im Schnitt gemäß dem Pfeil II der Fig. 1 (unter Weglassung der Rollenbahnen). Fig. 3 zeigt in zu Fig. 1 analoger Darstellung eine weitere Ausführungsform der erfindungsgemäßen Vorrichtung zum Austauschen der an der Außen- bzw. Unterseite der Strangführung angeordneten Rollen teilweise im Schnitt, Fig. 4 ist eine Ansicht des Schlittens in Richtung des Pfeiles IV der Fig. 3 teilweise im Schnitt. In Fig. 5 ist eine weitere Ausführungsform in zu Fig. 1 analoger Darstellung gezeigt.The device according to the invention is explained in more detail with reference to the schematic drawing in three exemplary embodiments, wherein FIG. 1 shows a longitudinal section through part of a schematically illustrated strand guide, in which a carriage according to a first embodiment for replacing the one seated on the inside or top of the strand guide Roles is shown. Fig. 2 shows a view of the carriage partially in section according to the arrow II of Fig. 1 (omitting the roller tracks). 3 shows, in a representation analogous to FIG. 1, a further embodiment of the device according to the invention for exchanging the rollers arranged on the outside or underside of the strand guide, partly in section, FIG. 4 is a view of the carriage in the direction of arrow IV of FIG 3 partly in section. 5 shows a further embodiment in a representation analogous to FIG. 1.

Mit 1 ist die innere und mit 2 die äußere Rollenbahn einer Strangführung bezeichnet, zwischen deren Stützrollen 3 während des Gießens der Strang geführt wird. Jeweils mehrere Stützrollen 3 sind über Lagerböcke 4 in einem Gerüstsegment 5 gelagert. Ein Schlitten 6, dessen Höhe h etwas kleiner ist als der Rollenbahnabstand d, ist mit einem strichpunktiert dargestellten Anfahrstrang 7 gelenkig verbunden und kann zusammen mit diesem zwischen den Rollenbahnen in Längsrichtung verschoben werden. Der Schlitten 6 weist zwei hintereinander liegende Rollensitze 8, 9 auf, die als die Rollen umgreifende, elastisch verformbare, federnde Klammern 10 ausgebildet sind.1 with the inner and 2 with the outer roller track of a strand guide is designated, between the support rollers 3 of which the strand is guided during casting. Several support rollers 3 are supported in a frame segment 5 via bearing blocks 4. A carriage 6, the height h of which is somewhat less than the roller conveyor Stand d, is articulated with a dotted line 7 and can be moved together with this between the roller tracks in the longitudinal direction. The carriage 6 has two roller seats 8, 9 lying one behind the other, which are designed as elastically deformable, resilient clamps 10 encompassing the rollers.

Jeder der Rollensitze ist an einem am Schlitten 6 angelenkten Schwenkarm 11 unbeweglich befestigt, kann jedoch, wie am unteren Rollensitz 8 im einzelnen dargestellt ist, durch Lösen eines Bolzens 12 vom Schwenkarm 11 abgezogen werden. Der Schwenkarm ist als Winkelhebel ausgebildet, der im Schnittpunkt seiner Hebelsarme 13', 13" am Schlitten angelenkt ist. Einer der Hebelsarme 13' trägt den Rollensitz 8 bzw. 9; der andere Hebelsarm 13" ist an einem Kolben eines Druckmittelzylinders 14, der am Schlitten 6 gelenkig befestigt ist, angelenkt. Mit Hilfe der Druckmittelzylinder 14 sind die Rollensitze aus einer im Schlitten zurückgezogenen Transportposition A (vgl. oberer Rollensitz in Fig. 1) in eine aus dem Schlitten vorragende Eingriffsposition B (vgl. unterer Rollensitz in Fig. 1) bzw. umgekehrt verschwenkbar.Each of the roller seats is immovably attached to a pivot arm 11 articulated on the slide 6, but, as is shown in detail on the lower roller seat 8, can be pulled off the pivot arm 11 by loosening a bolt 12. The swivel arm is designed as an angle lever which is articulated on the slide at the intersection of its lever arms 13 ', 13 ". One of the lever arms 13' carries the roller seat 8 or 9; the other lever arm 13" is on a piston of a pressure medium cylinder 14, which on Carriage 6 is articulated, articulated. With the aid of the pressure medium cylinders 14, the roller seats can be pivoted from a transport position A retracted in the carriage (cf. upper roller seat in FIG. 1) into an engagement position B protruding from the carriage (cf. lower roller seat in FIG. 1) or vice versa.

Der Schlitten selbst ist aus Seitenwangen 15 gebildet, die über eine Traverse 16 und Rohre 17 miteinander verbunden sind.The carriage itself is formed from side walls 15, which are connected to one another via a cross member 16 and tubes 17.

Infolge der Länge der auszutauschenden Rollen sind jeweils zwei Schwenkarme 11 parallel zueinander angeordnet und zwecks Gleichlaufes mittels eines Rohres 18 miteinander verbunden. Die Seitenwangen 15 des Schlittens sind über das untere Rohr 17, das einerseits die Seitenwangen 15 und anderseits an einer Traverse 19 angeschweißte Halterungen 20 durchsetzt, mit dieser Traverse 19 gelenkig verbunden. Zur Begrenzung der Beweglichkeit der Seitenwangen des Schlittens gegenüber der Traverse 19 sind an den Seitenwangen 15 Anschläge 20 vorgesehen.Due to the length of the roles to be exchanged, two swivel arms 11 are arranged parallel to each other and connected to each other by means of a tube 18 for the purpose of synchronism. The side cheeks 15 of the carriage are connected to the latter via the lower tube 17, which on the one hand passes through the side cheeks 15 and on the other hand, brackets 20 welded to a crossmember 19 Traverse 19 articulated. In order to limit the mobility of the side cheeks of the slide relative to the cross member 19, stops 20 are provided on the side cheeks 15.

Die Funktionsweise der Vorrichtung ist folgende:

  • ' Eine neue bzw. intakte Strangführungsrolle 21 wird in einen der Rollensitze 9 des Schlittens 6 eingelegt. Der Schlitten 6 wird an den Kaltstrang 7 gekuppelt, der mit Hilfe der in der Strangführung vorgesehenen antreibbaren Rollen in die Strangführung eingefädelt wird. Hierbei befinden sich die Rollensitze 8, 9 in Transportposition A. Der Schlitten 6 wird so weit eingeführt, bis sich der zunächst leere Rollensitz 8 in Höhe der schadhaften Rolle 22 befindet. Mit Hilfe des hydraulischen Druckmittelzylinders 14 werden sodann die Schwenkarme 11, die den leeren Rollensitz 8 tragen, zur auszutauschenden Rolle 22 hin in Eingriffsposition B bewegt, bis die Klammern 10 die schadhafte Rolle 22 umschließen. Nach Lösen der schadhaften Rolle 22 aus den Lagerböcken 4 werden die Schwenkarme 11 wieder in die Transportposition A zurückgeschwenkt.
The device works as follows:
  • A new or intact strand guide roller 21 is inserted into one of the roller seats 9 of the carriage 6. The carriage 6 is coupled to the cold strand 7, which is threaded into the strand guide with the aid of the drivable rollers provided in the strand guide. Here, the roller seats 8, 9 are in the transport position A. The carriage 6 is inserted until the initially empty roller seat 8 is at the level of the damaged roller 22. With the help of the hydraulic pressure medium cylinder 14, the swivel arms 11, which carry the empty roller seat 8, are then moved toward the roller 22 to be exchanged into the engagement position B until the clamps 10 enclose the defective roller 22. After loosening the defective roller 22 from the bearing blocks 4, the pivot arms 11 are pivoted back into the transport position A.

Anschließend wird der Schlitten so weit verfahren, bis sich die neue Rolle 21 in Höhe der Lücke befindet, an der sich die schadhafte Rolle 22 befunden hat. Mit Hilfe des hydraulischen Druckmittelzylinders 14 wird nun die neue Rolle 21 in die Lücke eingesetzt. Nach Montage der Rolle an den Lagerböcken werden die Schwenkarme 11 wieder in Transportposition A zurückgeschwenkt, die Klammern 10 klinken selbsttätig von der Rolle aus. Infolge der als federnde Klammern 10 ausgebildeten Rollensitze 8, 9 ist es möglich, diese für Rollen unterschiedlichen Durchmessers zu verwenden.The carriage is then moved until the new roller 21 is at the level of the gap at which the defective roller 22 was located. With the help of the hydraulic pressure medium cylinder 14, the new roller 21 is now inserted into the gap. After mounting the roller on the pedestals, the swivel arms 11 are pivoted back into transport position A, the clamps 10 release automatically from the roller. Due to the designed as resilient clamps 10 R olle seats 8, 9 it is possible to use these different roles for diameter.

Die federnden Klammern 10 ermöglichen ein sicheres und besonders einfaches Wechseln der Rollen der bogeninneren bzw. oberen Strangführungsbahn 1. Sollen die Rollen der bogenäußeren bzw. unteren Rollenbahn 2 gewechselt -werden, muß eine Vorkehrung getroffen werden, daß die in den Rollensitzen eingesetzten Rollen nicht zufolge ihres Eigengewichts wieder aus den Rollensitzen fallen. Eine Ausführungsform, bei der dies verwirklicht ist, ist in den Fig. 3 und 4 dargestellt.The resilient brackets 10 enable a safe and particularly simple change of the roles of the inner or upper strand guide track 1. If the roles of the outer or lower role track 2 are to be changed, a precaution must be taken that the roles used in the role seats are not accordingly of their own weight falling out of the reel seats. An embodiment in which this is realized is shown in FIGS. 3 and 4.

Wie aus Fig. 3 ersichtlich ist, ist ein gabelförmiger Rollensitz 23 gelenkig an einem Schwenkarm 24 befestigt, der in einem Schlitten 25 um.die Achse 26 schwenkbar gelagert ist. Der Schwenkarm 24 ist wiederum als Winkelhebel ausgebildet und mittels eines Druckmittelzylinders 27, der einerseits an einem Hebelsarm 28 des Schwenkarmes und anderseits am Schlitten 25 angelenkt ist, betätigbar. Der gabelförmige Rollensitz 23 weist einen Fortsatz 29 auf, der in Eingriffsposition B des Rollensitzes 23 an der der auszuwechselnden Rolle 22 benachbarten Rolle 3 anliegt und in Transportposition A des Rollensitzes 23 an einem Anschlag 30 des Schwenkarmes 24 anliegt. Dieser Fortsatz 29 bewirkt dadurch ein genaues Ausrichten des gabelförmigen Rollensitzes 23 mit der Gabelöffnung zur auszutauschenden Rolle 22, wodurch der gabelförmige Rollensitz 23 auch zwischen eng benachbarten Rollen 3 leicht in Eingriffsposition B verschwenkbar ist.As can be seen from Fig. 3, a fork-shaped roller seat 23 is articulated to a swivel arm 24 which is pivotally mounted about the axis 26 in a carriage 25. The swivel arm 24 is in turn designed as an angle lever and can be actuated by means of a pressure medium cylinder 27 which is articulated on the one hand on a lever arm 28 of the swivel arm and on the other hand on the slide 25. The fork-shaped roller seat 23 has an extension 29 which, in the engaged position B of the roller seat 23, bears against the roller 3 which is adjacent to the roller 22 to be replaced and in the transport position A of the roller seat 23 bears against a stop 30 of the swivel arm 24. This extension 29 thereby causes a precise alignment of the fork-shaped roller seat 23 with the fork opening to the roller 22 to be exchanged, as a result of which the fork-shaped roller seat 23 can also be easily pivoted into engagement position B between closely adjacent rollers 3.

Die Gabeln des gabelförmigen Rollensitzes sind von die Rollen hintergreifenden verschwenkbaren Riegeln 31, 32 gebildet. Die Riegel 31, 32 sind aus einer zu den Rollenachsen 3' parallel liegenden Position in eine zu den Rollenachsen querliegende Position, wie in Fig. 3 mit strichpunktierten Linien dargestellt, mit Hilfe eines von einem vorzugsweise hydraulisch betätigbaren Druckmittelzylinder antreibbaren Gestänges verschwenkbar.The forks of the fork-shaped roller seat are formed by swiveling bars 31, 32 engaging behind the rollers. The bolts 31, 32 are moved from a position parallel to the roller axes 3 'into a position transverse to the roller axes, as shown in FIG. 3 with dash-dotted lines a linkage which can be driven by a preferably hydraulically actuated pressure medium cylinder.

Wie aus Fig. 4, in der das Gestänge näher dargestellt ist, ersichtlich ist, sind zwei hydraulische Druckmittelzylinder 33 vorgesehen, die mit ihren Kolbenstangen am Schwenkhebel 34 angelenkt sind. Diese Schwenkhebel 34 sind einerseits mit dem Schlitten 25 gelenkig verbunden (bei 35) und anderseits am Hebelgestänge, welches aus jeweils einer ersten Schubstange 36, einem Winkelhebel 37, einer weiteren Schubstange 38 und einem Hebel 39 besteht, gelenkig verbunden. An dem Winkelhebel 37 und am Hebel 39 ist jeweils einer der Riegel 31, 32 befestigt. Anstelle der beiden Druckmittelzylinder 33 könnte auch nur ein einziger vorgesehen sind, wobei dann eine Verbindungsstange 40 zwischen den gegenüberliegenden Schwenkhebeln 34 vorgesehen ist, wie dies in Fig. 4 mit strichpunktierten Linien angedeutet ist.4, in which the linkage is shown in more detail, two hydraulic pressure medium cylinders 33 are provided, which are articulated with their piston rods on the pivot lever 34. These pivot levers 34 are articulated on the one hand to the slide 25 (at 35) and on the other hand articulated on the lever linkage, which consists of a first push rod 36, an angle lever 37, another push rod 38 and a lever 39. One of the bolts 31, 32 is fastened to the angle lever 37 and the lever 39. Instead of the two pressure medium cylinders 33, only a single one could also be provided, in which case a connecting rod 40 is provided between the opposite pivot levers 34, as is indicated in FIG. 4 by dash-dotted lines.

Die Funktionsweise dieser Ausführungsform ist ähnlich wie die der in den Fig. 1 und 2 dargestellten Ausführungsform. Es muß lediglich die Rolle, nachdem sie in den Rollensitz 23 eingelegt bzw..vom Rollensitz 23 seitlich umfaßt worden ist, durch Verschwenken der Riegel 31, 32 - durch Betätigen der Druckmittelzylinder 33 - im Rollensitz 23 fixiert werden.The operation of this embodiment is similar to that of the embodiment shown in FIGS. 1 and 2. It is only necessary to fix the roller in the roller seat 23 after it has been inserted into the roller seat 23 or has been laterally embraced by the roller seat 23 by pivoting the bolts 31, 32 - by actuating the pressure medium cylinders 33.

In Fig. 5 ist eine weitere Ausführungsform dargestellt, die für besonders eng benachbarte Rollenbahnen 1, 2, in denen auch die Rollen 3 besonders eng benachbart angeordnet sind, geeignet ist. Gemäß dieser Ausführungsform ist der Rollensitz 41, der hier ebenfalls als federnde Klammer 10 ausgebildet ist, gelenkig an einem im Schlitten 42 angelenkten Schwenkarm 43 (bei 44) angeordnet. Der Rollensitz 41 weist einen Fortsatz 45 auf, der in Transportposition A des Rollensitzes 41 an einem Anschlag 46 des Schlittens anliegt, wie dies in Fig. 5 mit voll ausgezogenen Linien dargestellt ist. Bei Verschwenken des Rollensitzes 41 in die aus dem Schlitten vorragende Eingriffsposition B, die in Fig. 5 strichpunktiert dargestellt ist, gelangt der Fortsatz 45 mit der der auszutauschenden Rolle benachbarten Rolle 3 in Eingriff. Die genaue Ausrichtung des Rollensitzes 41 während dieser Schwenkbewegung wird durch eine winkelförmige Klinke 47 bewirkt, die am Schwenkhebel 43 an der Achse 48 schwenkbar befestigt ist. Ein Arm 49 der Klinke 47 drückt mit einem Ansatz 50 stets, d.h. auch während der Schwenkbewegung, gegen den Fortsatz 45 des Rollensitzes 41 und der andere Arm 51 dieser Klinke 47 liegt an einer im Schlittengehäuse drehbar montierten Rolle 52 an. Durch diese Klinke wird der Fortsatz stets parallel zu den Rollenbahnen 1, 2 bzw. parallel zur Ober- bzw. Unterseite des Schlittens 42 gehalten. Zur Bewegung des Schwenkarmes 43 dient wie bei den zuvor beschriebenen Ausführungsformen ein Druckmittelzylinder 53.5 shows a further embodiment which is suitable for particularly closely adjacent roller conveyors 1, 2, in which the rollers 3 are also arranged particularly closely adjacent. According to this embodiment, the roller seat 41, which is likewise designed here as a resilient bracket 10, is arranged in an articulated manner on a swivel arm 43 (at 44) articulated in the carriage 42. The roller seat 41 has an extension 45 which is in the transport position A of the roller seat 41 abuts a stop 46 of the carriage, as shown in Fig. 5 with full lines. When the roller seat 41 is pivoted into the engagement position B protruding from the slide, which is shown in broken lines in FIG. 5, the extension 45 comes into engagement with the roller 3 adjacent to the roller to be replaced. The exact alignment of the roller seat 41 during this pivoting movement is effected by an angular pawl 47 which is pivotally attached to the pivot lever 43 on the axis 48. An arm 49 of the pawl 47 always presses against the extension 45 of the roller seat 41 with an extension 50, ie also during the pivoting movement, and the other arm 51 of this pawl 47 bears against a roller 52 which is rotatably mounted in the slide housing. By means of this pawl, the extension is always held parallel to the roller tracks 1, 2 or parallel to the top or bottom of the carriage 42. As in the previously described embodiments, a pressure medium cylinder 53 serves to move the swivel arm 43.

Die Erfindung ist nicht auf die dargestellten Ausführungsbeispiele beschränkt, sondern kann in verschiedener Hinsicht modifiziert werden. Beispielsweise kann als Stelltrieb für die Schwenkarme der Rollensitze auch ein beliebiges Antriebsgerät vorgesehen sein. Die Rollensitze müssen auch nicht unbedingt an Schwenkarmen befestigt sein, sie können auch durch andere Verstellmittel aus dem Schlitten in die Eingriffsposition und zurück bewegt werden, beispielsweise mittels wagenheberähnlicher Konstruktionen, mittels Stellspindeln etc.The invention is not restricted to the exemplary embodiments shown, but can be modified in various ways. For example, any drive device can also be provided as an actuator for the swivel arms of the roller seats. The roller seats also do not necessarily have to be attached to swivel arms, they can also be moved from the slide into the engagement position and back by other adjusting means, for example by means of jack-like structures, by means of adjusting spindles, etc.

Beim Rollenwechsel können jeweils mehrere Schlitten hintereinander an den Anfahrstrang angelenkt werden, wobei Schlitten gemäß verschiedener Ausführungsformen miteinander kombinierbar sind. Dies ist erforderlich, wenn man beispielsweise in einem Arbeitsgang schadhafte Rollen aus der oberen und unteren Rollenbahn ausbauen und in einem anderen Arbeitsgang diese schadhaften Rollen in der oberen und unteren Rollenbahn ersetzen will.When changing roles, several carriages can be articulated in succession to the starting line, with carriages according to different embodiments can be combined with each other. This is necessary if, for example, you want to remove damaged rollers from the upper and lower roller conveyor in one operation and replace these defective rollers in the upper and lower roller conveyor in another operation.
