Description

Die Erfindung bezieht sich auf eine Leiteinrichtung für ein schienengeführtes Fahrzeug mit einem Fahrwerk, welches einen Fahrwerkskörper mit Führungsrollen mit vertikaler Drehachse aufweist, die an den Fahrschienen seitlich abrollen, und einem Schaltelement, das sich in Fahrtrichtung vor den Führungsrollen befindet und über eine Bedienungseinrichtung um eine vertikale Achse auslegerartig schwenkbar ist, um bei Verzweigstellen der Fahrschienen die Fahrtrichtung auszuwählen, wobei an diesen Verzweigstellen zwischen zwei mit U-Profil ausgebildeten Schienenabschnitten dem Fahrzeug entgegengerichtete, um eine senkrechte Achse schwenkbare Leitfahnen angeordnet sind, die von dem Schaltelement umgeschalten werden und die in ihren beiden Endstellungen vorzugswiese an einer Seitenwand der Schiene anliegen.The invention relates to a guide device for a rail-guided vehicle with a chassis, which has a chassis body with guide rollers with a vertical axis of rotation, which roll laterally on the rails, and a switching element, which is located in the direction of travel in front of the guide rollers and an operating device by a vertical axis is pivotable in the manner of a cantilever, in order to select the direction of travel when branching the rails, and at these branches between two rail sections formed with a U-profile, the vehicle is arranged in opposite directions and is pivotable about a vertical axis, which are switched by the switching element and which are in their Both end positions are preferably on a side wall of the rail.

Insbesondere bezieht sich die Erfindung auf eine Leiteinrichtung für einspurige Fahrzeuge wie sie beispielsweise bei Regalförderzeugen Verwendung finden. So ist es bekannt, in einen Gang eine Bodenschiene und eine Oberschiene anzubringen, wobei in den Schienen ein Regalbedienungsgerät fährt, das ein Fahrgestell mit einem Hubrahmen aufweist, auf dem eine Hub- bzw. Regalbedienungseinrichtung auf- und abfahrbar istIn particular, the invention relates to a guide device for single-track vehicles as used, for example, in rack-type conveyors. It is known to mount a floor rail and a top rail in one aisle, a rack operating device running in the rails having a chassis with a lifting frame on which a lifting or rack operating device can be moved up and down

Die Regalbedienungseinrichtung ist mit einer Kabine versehen, von der aus dessen Auf- und Abwärtsbewegung und die Vor- und Rückfahrt des Regalbedienungsgerätes steuerbar ist.The rack operating device is provided with a cabin from which the up and down movement and the forward and backward travel of the rack operating device can be controlled.

Es gibt Regalbedienungsgeräte, die von einem Regalgang in einen quer oder parallel liegenden Gang über ein Kurvenstück der Schiene hinüberwechseln können. Dabei sind die Fahrwerksräder drehbar am Fahrwerk gelagert. Es ist weiters bekannt, daß bei Schienenverzweigungen verschiedene Wechseleinrichtungen vorgesehen sind, beispielsweise Weichen.There are rack operating devices that can change from a rack aisle to a transverse or parallel aisle over a curved section of the rail. The chassis wheels are rotatably mounted on the chassis. It is also known that various changing devices are provided for rail junctions, for example switches.

Es ist auch ein Schienensystem bekannt, bei dem bei den Verzweigungsstellen neben einer eigentlichen Leitschiene Führungsschienen vorgesehen sind. Das Lenken des Fahrzeuges erfolgt durch Einsetzen von verschiedenen Führungsrollen des Fahrzeuges in die Führungsschiene. Hiebei ist eine mittlere Führungsrolle ständig im Eingriff, während in der Kurvenfahrt abwechselnd eine linke oder rechte Führungsrolle mit der zugehörigen Führungsschiene in Eingriff gebracht wird.A rail system is also known, in which guide rails are provided at the branching points in addition to an actual guide rail. The vehicle is steered by inserting various guide rollers of the vehicle into the guide rail. A middle guide roller is constantly engaged, while a left or right guide roller is alternately engaged with the associated guide rail when cornering.

Ein derartiges System ist in der DE-PS 21 00 854 beschrieben. Ein weiteress System, bei dem die Schaltrollen an Schalthebeln horizontal schwenkbar sind, ist in der AT-PS 334 971 beschrieben. Auch dieses System benötigt zusätzliche Richtungswahlschienen.Such a system is described in DE-PS 21 00 854. A further system in which the shift rollers on shift levers can be swiveled horizontally is described in AT-PS 334 971. This system also requires additional direction selection rails.

Bei einer Verzweigungsstelle wird durch Schwenken der Leitfahnen die Geradefahrt oder die Kurvenfahrt eingeleitet. Das Schwenken der Leitfahne erfolgt über das Schaltelement direkt vom Gerät aus.At a branching point, straight driving or cornering is initiated by swiveling the guide flags. The guide flag is swiveled directly from the device via the switching element.

Die DE-PS 497 725 beschreibt eine Laufkatze, die Schaltelemente aufweist, mit denen bei Abzweigungen der Schienen angeordnete Leitfahnen umgeschwenkt werden können. Um das Umschwenken zu ermöglichen, muß zwischen der Spitze der Leitfahne und dem Rand der U-förmigen Schiene stets ein Spalt sein.DE-PS 497 725 describes a trolley which has switching elements with which guide vanes arranged at branches of the rails can be pivoted. In order to enable the pivoting, there must always be a gap between the tip of the guide vane and the edge of the U-shaped rail.

Eine derartige Weichenschaltung ist bei einem Regalbedienungsgerät wegen der auftretenden hohen Belastung nicht einsetzbar.Such a switch circuit cannot be used in a rack operating device because of the high load that occurs.

Aufgabe der Erfindung ist es, eine ähnliche Leiteinrichtung für schienengeführte Fahrzeuge, insbesondere für Regalbedienungsgeräte zu schaffen, die direkt vom Gerät aus steuerbar ist und die gegenüber dem bekannten Stand der Technik den Vorteil einer gleichmäßigeren Führung des Gerätes bei den Abzweigstellen aufweist und bei der keine außerhalb der Schiene liegenden Führungselemente notwendig sind.The object of the invention is to provide a similar guide device for rail-guided vehicles, in particular for storage and retrieval machines, which can be controlled directly from the device and which has the advantage over the known prior art that the device is guided more evenly at the branch points and none outside the guide elements lying on the rail are necessary.

Dies wird erfindungsgemäß dadurch erreicht, daß die Leitfahnen ein über die Seitenstege der Fahrschienen hinausragendes Teil aufweisen, an dem das Schaltelement beim Umschalten angreift und dadurch, daß das Schaltelement oberhalb der Seitenstege der Fahrschienenangeordnet ist.This is achieved according to the invention in that the guide vanes have a part which projects beyond the side webs of the travel rails, on which the switching element engages when switching over, and in that the switching element is arranged above the side webs of the travel rails.

Da gemäß der Erfindung die Leitfahnen an den Schienenwänden anlie gen können, ist die notwendige Stabilität gegeben, wenn die Führungsrollen daran anstoßen.Since, according to the invention, the guide vanes can lie against the rail walls, the necessary stability is given when the guide rollers touch it.

Daß die Leitfahnen satt an den Seitenstegen der Fahrschienen anliegen, ist bei einem schweren Fahrzeug, wie z.B. einem Regalbedienungsgerät, von größter Bedeutung. So treten bei der Kurvenfahrt Seitenkräfte von 500 -1500 daN auf. Dies würde zu einem ständigen Anschlagen der Leitfahne an der Seitenwand der Schiene führen.With heavy vehicles such as e.g. the guiding flags fit snugly on the side webs of the rails. a storage and retrieval machine, of paramount importance. Lateral forces of 500-1500 daN occur when cornering. This would lead to the guide flag constantly striking the side wall of the rail.

Des weiteren könnte es passieren, daß die vordere Führungsrolle, die sich auf derselben Seite wie die Leitfahne befindet, frontal auf die Spitze der Leitfahne auffährt, wenn diese sich in einem, auch geringen Abstand zur Schienenseitenwand befindet. Dies hätte einen Bruch der Leitvorrichtung zur Folge.Furthermore, it could happen that the front guide roller, which is located on the same side as the guide vane, hits the tip of the guide vane frontally, even if this is at a small distance from the rail side wall. This would result in the guide device breaking.

Eine weitere Aufgabe der Erfindung ist es, eine Leiteinrichtung der eingangs erwähnten Art derartig auszugestalten, daß das Fahrzeug außerhalb der Verzweigstellen auf einer herkömmlichen Schiene, beispielsweise einer Eisenbahnschiene geführt sein kann.A further object of the invention is to design a guide device of the type mentioned at the outset in such a way that the vehicle can be guided on a conventional rail, for example a railroad rail, outside the branch points.

Dies wird erfindungsgemäß dadurch erreicht, daß die Fahrschienen vor und nach den Verzweigstellen einen seitlich freien Schienenkopf aufweisen und daß die Führungsrollen, die in der Höhe versetzbar gelagert sind, in diesen Bereichen an den Schienenkopfflanken abrollen und die Fahrschienen zwischen sich aufnehmen (Fig. 4).This is achieved according to the invention in that the rails have a laterally free rail head before and after the branching points and that the guide rollers, which are displaceably mounted in height, roll on the rail head flanks in these areas and accommodate the rails between them (FIG. 4) .

Vorteilhaft ist dabei vorgesehen, daß vor den Verzweigstellen beidseitig des freien Schienenkopfes Rampen angeordnet sind, die zu dem mit U-Profil ausgebildeten Schienenabschnitt führen, wobei die Führungsrollen entlang der Rampen angehoben werden.It is advantageously provided that ramps are arranged on both sides of the free rail head in front of the branch points, which lead to the rail section formed with a U-profile, the guide rollers being raised along the ramps.

Ein Ausführungsbeispiel der Erfindung sieht vor, daß Lagerachsen der Führungsrollen mit ihren unteren Enden an den Rampen anliegen, wobei die Lagerachsen vorteilhaft von Federn nach unten gedrückt werden, damit die Führung an der Fahrschiene auch in der Geradefahrt gewährleistet ist. Das Absenken der Führungsrollen kann auch durch die Schwerkraft erfolgen. Eventuell ist eine Verriegelungseinrichtung vorgesehen.An embodiment of the invention provides that bearing axles of the guide rollers rest with their lower ends on the ramps, the bearing axles advantageously being pressed down by springs so that guidance on the running rail is also ensured in straight travel. The guide rollers can also be lowered by gravity. A locking device may be provided.

Um einen sicheren Eingriff des Schaltelementes des Fahrzeuges mit der Leitfahne zu erzielen, ist vorgesehen, daß das Schaltelement in der Schaltstellung seitlich über die Seitenstege der Führungsschienen hinaus ragt.In order to achieve a secure engagement of the switching element of the vehicle with the guide vane, it is provided that the switching element in the switching position projects laterally beyond the side webs of the guide rails.

Das aus den Schienen ragende Teile der Leitfahne wird vorteilhaft von einem Bolzen gebildet, der am freien Ende der Leitfahne angeordnet ist. Der Bolzen kann eine Rolle tragen.The part of the guide vane protruding from the rails is advantageously formed by a bolt which is arranged at the free end of the guide vane. The bolt can carry a role.

Nachfolgend wird ein Ausführungsbeispiel der Erfindung anhand der Figuren der beiliegenden Zeichnungen eingehend beschrieben.An exemplary embodiment of the invention is described in detail below with reference to the figures in the accompanying drawings.

Die Fig. 1 zeigt schematisch eine Ansicht eines Regalbedienungsgerätes mit einer erfindungsgemäßen Leiteinrichtung, die Fig. 2 zeigt ebenso schematisch eine Seitenansicht einer Verzweigungsstelle, die Fig. 3 zeigt schematisch eine Draufsicht auf eine Verzweigungsstelle nach Fig. 2, die Fig. 4 zeigt einen Schnitt nach der Linie A-A der Fig. 3, die Fig. 5 zeigt einen Schnitt nach der Linie B-B der Fig. 3, die Fig.6 zeigt eine Seitenansicht der Verzweigstelle analog der Fig. 2, wobei das Fahrzeug bei der Einfahrt in die Verzweigstelle gezeigt ist, die Fig. 7 zeigt die gleiche Verzweigstelle mit der gleichen Fahrzeugstellung in der Draufsicht, wobei die Leitfahne und das Schaltelement sich in der Stellung für die Geradeausfahrt befinden, und die Figuren 8 bis 10 zeigen Draufsichten auf die Verzweigstelle in verschiedenen Stadien der Kurvenfahrt.Fig. 1 shows schematically a view of a rack operating device with a guide device according to the invention, Fig. 2 also shows schematically a side view of a branch point, Fig. 3 shows schematically a plan view of a branch point according to Fig. 2, Fig. 4 shows a section along line AA of FIG. 3, FIG. 5 shows a section along line BB of FIG. 3, FIG. 6 shows a side view of the branching point analogous to FIG. 2, the vehicle being shown when entering the branching point 7 shows the same branching point with the same vehicle position in a top view, with the guide vane and the switching element in the position for driving straight ahead, and FIGS. 8 to 10 show top views of the branching point in different stages of cornering.

Im nachfolgenden wird jeweils nur der in Fahrtrichtung vordere Fahrwerkskörper 6 des Regalbedienungsgerätes beschrieben, der hintere Fahrwerkskörper folgt beim Passieren der Verzweigstelle ohne weitere Maßnahmen dem ersten Fahrwerkskörper 6.In the following, only the front chassis body 6 of the rack operating device, which is in the direction of travel, is described; the rear chassis body follows the first chassis body 6 without further measures when it passes the branch point.

Das in der Fig. 1 dargestellte Regalbedienungsgerät weist in herkömmlicher Weise ein unteres Fahrwerk 1, einen Hubmast 2 und ein oberes Leitwerk 3 auf. Am Hubmast 2 ist der Hubschlitten 14 vertikal fahrbar gelagert. Im Hubschlitten 14 befindet sich auch die Bedienungskabine, von der aus die Steuerung der Leiteinr ichtung erfolgt.The shelf operating device shown in FIG. 1 has a lower undercarriage 1, a lifting mast 2 and an upper tail unit 3 in a conventional manner. The lifting carriage 14 is mounted on the lifting mast 2 in a vertically movable manner. In the lifting carriage 14 there is also the operating cabin from which the control of the control device takes place.

Das Leitwerk 3 der oberen Führungseinrichtung weist obere Führungsrollen 4 auf, die in einer oberen Führungsschiene 5 geführt sind. Auf die besondere Art der oberen Führung an den Verzweigungsstellen wird im Rahmen dieser Beschreibung nicht eingegangen.The tail unit 3 of the upper guide device has upper guide rollers 4 which are guided in an upper guide rail 5. The special type of upper guide at the branching points is not dealt with in the context of this description.

Das Fahrwerk 1 weist vorne und hinten je einen Fahrwerkskörper 6 auf, der im Ausführungsbeispiel jeweils eine Laufrolle 7 und vier Führungsrollen 8 trägt. Der Fahrwerkskörper 6 kann am Fahrwerk 1 sowohl starr als auch seitenverschiebbar oder drehbar gelagert sein.The undercarriage 1 has one undercarriage body 6 each at the front and rear, which in the exemplary embodiment carries one roller 7 and four guide rollers 8. The undercarriage body 6 can be mounted on the undercarriage 1 both rigidly and also laterally displaceably or rotatably.

Die Führungsrollen 8 sind entland einer unteren Fahrschiene 9 geführt.The guide rollers 8 are guided along a lower rail 9.

Die unteren Fahrschienen 9 werden außerhalb der Verzweigstellen meist von herkömmlichen Eisenbahnschienen gebildet, und die Führungsrollen 8 laufen links und rechts des Schienenkopfes 10 an den Schienenkopfflanken ab. Das Fahrzeug ist somit sicher auf der Fahrschiene 9 geführt.The lower rails 9 are usually formed by conventional railroad tracks outside the branching points, and the guide rollers 8 run to the left and right of the rail head 10 on the rail head flanks. The vehicle is thus safely guided on the rail 9.

Im Bereich einer jeden Verzweigstelle sind die Fahrschienen als U-Profil ausgeführt, d. h. es sind seitliche Führungswände 17 vorgesehen, an denen die Führungsrollen 8 nunmehr innen ablaufen. Seitlich des Schienenkopfes 10 sind, wie aus der Fig. 5 ersichtlich, horizontale Seitenstege 18 vorgesehen.In the area of each branch, the rails are designed as a U-profile. H. lateral guide walls 17 are provided, on which the guide rollers 8 now run off on the inside. As can be seen from FIG. 5, horizontal side webs 18 are provided on the side of the rail head 10.

Zu den horizontalen Seitenstegen 18 führen schräge Rampen 16. Durch die Rampen 16 werden die Führungsrollen 8, die auf Achsen 19 gelagert sind, angehoben, sodaß der Fahrwerkskörper 6 ungehindert in den U-Profilbereich der Fahrschienen 9 einfahren kann.Inclined ramps 16 lead to the horizontal side webs 18. The ramps 16 raise the guide rollers 8, which are mounted on axles 19, so that the chassis body 6 can move freely into the U-profile area of the rails 9.

In dem gezeigten Ausführungsbeispiel ist die Eisenbahnschiene, die die Fahrschiene 9 bildet, durchgehend ausgeführt und wird im Bereich der Verzweigstelle von den Seitenstegen 18 ergänzt. Es wäre jedoch auch möglich, die Eisenbahnschiene als Fahrschiene 9 nur bis zum Ende 16ʹ der Rampe gehen zu lassen und anschließend bis zum Ende 16ʹ der gegenüberliegenden Rampe 16 einen auswechselbaren Verschleißteil am Flachstahl vorzusehen. Die Achsen 19 der Führungsrollen 8 können beispielsweise von Federn 20 beaufschlagt sein, die sie beim Verlassen der Verzweigstelle hinunterdrücken.In the exemplary embodiment shown, the railroad track that forms the travel rail 9 is continuous and is supplemented by the side webs 18 in the region of the branching point. However, it would also be possible to let the railroad track 9 go only up to the end 16ʹ of the ramp and then to provide a replaceable wear part on the flat steel up to the end 16ʹ of the opposite ramp 16. The axes 19 of the guide rollers 8 can be acted upon, for example, by springs 20, which press them down when leaving the branch point.

Die Fahrwerkskörper 6 sind mit keilförmigen Schaltelementen 11 versehen, die sich in Fahrtrichtung jeweils vor den vordersten Führungsrollen 8 befinden.The chassis bodies 6 are provided with wedge-shaped switching elements 11, which are located in front of the foremost guide rollers 8 in the direction of travel.

In den Figuren 2 und 3 ist die Leitfahne 12 jeweils in der Stellung gezeigt, die ein Geradeausfahren des Regalbedienungsgerätes bedingen würde. Im geraden Regalgang wird das Regalbedienungsgerät, welches auf zwei Fahrwerkskörpern 6 läuft, auf der Fahrschiene 9 mittels der Führungsrollen 8 geführt.In FIGS. 2 and 3, the guide vane 12 is shown in the position that would require the rack operating device to move straight ahead. In the straight rack aisle, the rack operating device, which runs on two undercarriage bodies 6, is guided on the running rail 9 by means of the guide rollers 8.

Bei den Verzweigungsstellen werden die Führungsrollen durch die Rampen 16 angehoben, und die seitliche Führung des Fahrwerkskörpers 6 wird nun von den Seitenwänden 17 des U-förmigen Bereiches der Fahrschiene 9 übernommen.At the branching points, the guide rollers are raised by the ramps 16, and the lateral guidance of the undercarriage body 6 is now carried out by the side walls 17 of the U-shaped area of the running rail 9.

In der in den Figuren, 2, 3, 6 und 7 gezeigten Situation fährt das Regalbedienungsgerät geradeaus.In the situation shown in FIGS. 2, 3, 6 and 7, the rack operating device moves straight ahead.

Soll das Regalbedienungsgerät 1 um die Kurve fahren, wird das Schaltelement 11, wie in der Fig. 8 gezeigt, in Stellung gebracht. Das Schaltelement 11 ragt dabei über den Steg 17 der Fahrschiene 9 im U-Profilbereich seitlich hinaus. Wie bereits erwähnt, ist das Schaltelement 11 oberhalb der Fahrschiene 9 angeordnet.If the storage and retrieval device 1 is to travel around the curve, the switching element 11 is brought into position, as shown in FIG. 8. The switching element 11 protrudes laterally beyond the web 17 of the rail 9 in the U-profile area. As already mentioned, the switching element 11 is arranged above the running rail 9.

Bei der Weiterfahrt des Regalbedienungsgerätes drückt die vordere Steuerfläche 13 des Schaltelementes 11 gegen den Bolzen 15, der an der Spitze der Leitfahne 12 angeordnet ist und ebenfalls über die Seitenstege 17 der Fahrschiene 9 hinausragt. Die Leitfahne 12 wird dadurch umgeschwenkt, bis sie beim gegenüberliegenden Steg 17 anliegt und sich daran abstützt. Das Regalbedienungsgerät fährt nun, wie in der Fig. 10 gezeigt, um die Kurve. Dabei ist von Bedeutung, daß die Leitfahne 12 satt am Steg 17 anliegen kann und auch nicht davon abrückt, wenn der erste Fahrwerkskörper 6 vorbeigefahren ist. Es kommt also zu keinem Schlagen der Leitfahnen 12.When the rack operating device continues to travel, the front control surface 13 of the switching element 11 presses against the bolt 15, which is arranged at the tip of the guide vane 12 and also protrudes beyond the side webs 17 of the travel rail 9. The guide vane 12 is thereby pivoted until it rests against the opposite web 17 and is supported on it. The shelf operating device now moves around the curve, as shown in FIG. 10. It is important that the guide vane 12 can rest snugly against the web 17 and also not move away from it when the first chassis body 6 has passed. There is therefore no hitting of the guiding flags 12.

Der zweite Fahrwerkskörper 6 des Regalbedienungsgerätes folgt ohne weitere Maßnahmen dem ersten Fahrwerksk örper 6.The second chassis body 6 of the rack operating device follows the first chassis body 6 without further measures.

Nach Passieren der Verzweigstelle, d. h. nach erfolgter Kurven oder Geradeausfahrt werden die Führungsrollen 8 über die hintere Rampe 16 wieder nach unten geleitet, so daß sie wieder an den Flanken des Schienenkopfes 10 anliegen und die Fahrschiene 9 ohne Seitenstege 17 die Führung des Regalbedienungsgerätes übernehmen kann.After passing the junction, that is, after cornering or driving straight ahead, the guide rollers 8 are guided downward again via the rear ramp 16, so that they rest against the flanks of the rail head 10 and the running rail 9 can take over the guidance of the storage and retrieval device without side webs 17.

Bei den Leitfahnen 12 kann eine Totpunktverriegelung vorgesehen sein, die gewährleistet, daß sie in der jeweils eingestellten Position bleiben. A dead center lock can be provided for the guide vanes 12, which ensures that they remain in the respectively set position.
