Description
Die Erfindung betrifft ein Transportsystem mit nebeneinander angeordneten
Schienen und darauf verfahrbarem und kurvengängigem Fahrzeug gemäß dem Oberbegriff des
Anspruches 1. The invention relates to a transport system with side by side
Rails and vehicle that can be moved and cornered according to the generic term of the
Ein derartiges Transportsystem ist bereits aus der schweizerischen Patentschrift CH-A-30 01 31 bekannt. Dieses Transportsystem besteht im wesentlichen aus einem kurvengängigen Schienenfahrzeug, das mit entsprechend ausgebildeten bodengeführten Schienen zusammenwirkt. Das Schienenfahrzeug besteht im wesentlichen aus vier Fahrwerken, die jeweils um senkrechte Achsen an einem Rahmen des Schienenfahrzeuges gelagert sind. In Fahrtrichtung gesehen sind an dem Rahmen an einer Fahrzeugseite etwa im Bereich der halben Länge des Fahrzeuges über Schwenkachsen jeweils Tragschenkel gelagert, die sich in Fahrtrichtung gesehen nach vorne und hinten erstrecken. An den ihrer Lagerung gegenüberliegenden Enden an den Tragschenkeln ist jeweils ein Fahrwerk gelagert. Desweiteren weist jedes Fahrwerk neben einem Laufrad zusätzliche Führungsrollen auf zum seitlichen Führen der Fahrwerke entlang der Schiene. Durch die Lagerung der Fahrwerke einer Schienenfahrzeugseite über die Tragschenkel an dem Rahmen des Schienenfahrzeuges ist es möglich, daß dieses Schienenfahrzeug einerseits Toleranzen der Spurweite der parallel zueinander verlaufenden Schienen ausgleichen kann und andererseits auch besonders enge Kurvenbereiche durchfahren kann, da hier bekannterweise sich die Spurweite für die Fahrwerke vergrößert. Hierdurch soll zusätzlich der Effekt erreicht werden, daß in den Kurven die Standsicherheit des Schienenfahrzeuges erhöht wird. Die Schienen dieses Transportsystems sind in den Geradstrecken und den Kurvenbereichen derart verlegt, daß sie eine nahezu konstante Spurweite aufweisen. Such a transport system is already known from the Swiss patent CH-A-30 01 31 known. This transport system consists essentially of a curve-going Rail vehicle with appropriately trained floor-guided rails cooperates. The rail vehicle essentially consists of four undercarriages are each mounted on a frame of the rail vehicle about vertical axes. In Driving direction are seen on the frame on a vehicle side approximately in the area half length of the vehicle on pivot axes each support leg, which is in Extend the direction of travel to the front and back. On their storage opposite ends on the support legs, a chassis is mounted. Furthermore, each running gear has additional guide rollers in addition to an impeller lateral guidance of the trolleys along the rail. By storing the trolleys a rail vehicle side on the support legs on the frame of the rail vehicle it is possible that this rail vehicle on the one hand tolerances of the gauge of the parallel can compensate for mutually extending rails and on the other hand also particularly narrow Can drive through curve areas, as is known here, the track width for the Chassis enlarged. This should also achieve the effect that in the curves the stability of the rail vehicle is increased. The rails of this Transport systems are laid in the straight sections and the curve areas so that they have an almost constant track width.
Aus der DE 36 01 837 C2 ist ein derartiges Schienenfahrzeug mit an einer Längsseite des Fahrzeugs über Tragschenkel angeordnete Fahrwerke bekannt. Auf der den Tragschenkeln gegenüberliegenden Seite sind die Fahrwerke mit Führungsrollen versehen, die an den Seiten der Schiene anliegen. Diese Ausbildung des Schienenfahrzeuges wurde gewählt, um einen ruhigeren Lauf des Fahrzeuges auch im Kurvenbereich zu erzielen. Dieses Schienenfahrzeug erweist sich als zuverlässig, um bei Strecken mit gleichem Schienenabstand etwaige Abstandstoleranzen auszugleichen. Darüber hinaus eignet es sich für die Durchfahrung von Kurven mit annähernd gleichem Schienenabstand und großen Radien. Das Verhältnis von dem Abstand der Schienen untereinander und dem Radius der kurvenäußeren Schiene beträgt minimal etwa 1 : 5.From DE 36 01 837 C2, such a rail vehicle is on one long side known chassis of the vehicle via support legs. On the Support legs on the opposite side are the trolleys with guide rollers provided that abut the sides of the rail. This training of Rail vehicle was chosen to ensure a smoother running of the vehicle in the Achieve curve area. This rail vehicle proves to be reliable For distances with the same rail spacing, any spacing tolerances balance. In addition, it is suitable for driving through curves with approximately the same rail spacing and large radii. The ratio of that Distance between the rails and the radius of the outer rail is at least about 1: 5.
Des weiteren ist in der DE 39 00 616 A1 ein Transportsystem mit einem schienengeführten Fahrzeug und einer Weiche beschrieben. Das Fahrzeug besteht im` wesentlichen aus einem rechtwinkligen Rahmen, in dessen Eckbereichen um senkrechte Achsen schwenkbare Fahrwerke angeordnet sind. Die Fahrwerke sind auf nebeneinander und voneinander beabstandeten Schienen verfahrbar. Die Schienen von unterschiedlichen Schienenstrecken kreuzen sich vorzugsweise unter einem rechten Winkel. In den Kreuzungsbereichen sind Weichen vorgesehen, um den Fahrzeugen einen Wechsel der Schienenstrecke zu ermöglichen. Die Weichen bestehen im wesentlichen aus in den Kreuzungspunkten der Schienen angeordneten Schienenabschnitten, die um eine vertikale Achse schwenkbar sind. Die Umsetzung eines Fahrzeuges von einer ersten auf eine zweite Schienenstrecke erfolgt nach Einfahren des Fahrzeugs in die Weiche durch Verfahren der schwenkbaren Schienenabschnitte. Hierdurch werden die Fahrwerke des Fahrzeuges ebenfalls um 90° geschwenkt, und anschließend ist das Fahrzeug in Richtung des zweiten Schienenstrangs verfahrbar.Furthermore, DE 39 00 616 A1 describes a transport system with a rail-guided vehicle and a switch described. The vehicle exists in the essentially from a rectangular frame in the corner areas around vertical axes swivel trolleys are arranged. The landing gear is on next to each other and spaced rails. The rails of different rail routes preferably cross under one right angle. In the crossing areas, switches are provided to the To enable vehicles to change the rail route. The course consist essentially of arranged in the crossing points of the rails Rail sections that are pivotable about a vertical axis. The implementation of a vehicle follows from a first to a second rail route Retracting the vehicle into the switch by moving the swivel Rail sections. This will also change the chassis of the vehicle Swiveled 90 °, and then the vehicle is in the direction of the second Rail track movable.
Dieses Transportsystem ermöglicht zwar eine platzsparende Umsetzung des Schienenfahrzeuges von einer ersten auf eine dazu rechtwinklige zweite Schienenstrecke, jedoch erweist sich diese Lösung für die Einsatzfälle, in denen das Fahrzeug beispielsweise nur eine 90°-Kurve fahren soll und keine Kreuzung vorliegt, als konstruktiv zu aufwendig.This transport system enables space-saving implementation of the Rail vehicle from a first to a right-angled second Rail route, however, this solution proves itself for the applications in which the For example, the vehicle should only drive a 90 ° curve and there is no intersection, as constructively too complex.
Der Erfindung liegt die Aufgabe zugrunde. ein Transportsystem zu schaffen, welches eine optimierte Kurvengängigkeit aufweist.The invention is based on the object. to create a transportation system which has optimized cornering.
Diese Aufgabe wird bei einem Transportsystem durch die im Anspruch 1 aufgeführten
Merkmale gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind in den
Unteransprüchen 2 bis 12 angegeben.This object is achieved in a transport system by those listed in
Erfindungsgemäß wird durch die Verlagerung der Schwenkachsen der Tragschenkel von den Fahrzeugenden zur Fahrzeugmitte hin erreicht, daß die Kurvengängigkeit des Fahrzeugs verbessert wird. Hierdurch können engere Kurven verschleißarm durchfahren werden. Durch die leicht von der Fahrzeuglängsseite nach innen versetzte Anordnung der Schwenkachsen wird ermöglicht, das Fahrzeug auch über Weichen gemäß der DE 39 00 616 A1 verfahren zu lassen.According to the invention by the displacement of the pivot axes of the support legs reached from the vehicle ends to the center of the vehicle that the cornering of the Vehicle is improved. This allows tighter curves to be worn be driven through. Through the slightly offset from the vehicle's long side Arrangement of the swivel axes is made possible, the vehicle also via switches to proceed according to DE 39 00 616 A1.
Als besonders vorteilhaft erweist sich die im Kurvenbereich in Richtung der äußeren Schiene eingezogene Ausbildung der inneren Schiene, so daß die Geschwindigkeit des inneren, hinteren Fahrwerks während der Durchfahrung des Kurvenbereiches gegen null geht, d.h im bevorzugten Fall fast stehenbleibt und seine Bewegungsrichtung nicht umkehrt. Das erfindungsgemäß ausgebildete Transportsystem stellt somit ein Fahrzeug zur Verfügung, das auch enge Kurvenradien sanft sowie ruckarm durchfahren kann. Enge Kurvenradien heißt hier, daß das Verhältnis von dem Abstand der Schienen untereinander und dem Radius der kurvenäußeren Schiene bis zu minimal etwa 1 : 1 betragen kann. Durch die erfindungsgemäße Ausbildung des Fahrzeugs und der Schiene werden die Querbeschleunigungen, die auf das auf dem Fahrzeug angeordnete Stückgut einwirken, sehr gering. Das Stückgut, insbesondere in Form von auf Paletten angeordneten Kartonagen, neigt somit nicht mehr zum Verrutschen auf dem Fahrzeug und aufwendige Befestigungsvorrichtungen für das Stückgut können entfallen. Des weiteren hat sich als vorteilhaft erwiesen, die senkrecht zur Fahrtrichtung ausgerichteten Achsen der Fahrwerke annähernd in den Eckpunkten eines gedachten Quadrates anzuordnen, da hierdurch selbst bei der Durchfahrung von engen Kurvenradien erreicht wird, daß der Schwerpunkt des Stückgutes innerhalb der Radaufstandsfläche bleibt und somit das Fahrzeug die Kurve stabil durchfährt.It proves to be particularly advantageous in the curve area in the direction of the outer one Rail retracted formation of the inner rail so that the speed of the inner, rear landing gear while passing through the corner area approaches zero, i.e. in the preferred case almost stops and his Direction of movement not reversed. The transport system designed according to the invention provides This means that a vehicle is available that is smooth and smooth even with tight corner radii can drive through. Narrow curve radii here means that the ratio of the distance of the rails with each other and the radius of the outer rail up to can be at least about 1: 1. Due to the inventive design of the Vehicle and rail are the lateral accelerations that occur on the General cargo arranged in vehicle act very little. General cargo, especially in Form of cardboard boxes arranged on pallets, therefore no longer tends to Slipping on the vehicle and elaborate fastening devices for that General cargo can be omitted. Furthermore, it has proven advantageous that Axis of the undercarriage aligned perpendicular to the direction of travel approximately in the To arrange the corner points of an imaginary square, because this means that even with the Passing through tight curve radii is achieved that the center of gravity of the General cargo remains within the wheel contact area and thus the vehicle turns drives through stably.
Besonders geeignet ist dieses Fahrzeug für die Verwendung auf im Querschnitt I-förmig ausgebildeten Schienen, die über Stützen auf dem Boden gehalten sind. Dieses Transportsystem eignet sich somit für die Umfahrung von zumeist im Grundriß rechtwinklig ausgebildeten Lagern, um von den einzelnen Lagerplätzen Stückgüter aufzunehmen oder an diese abzugeben. Die Erfindung ist auch für Fahrzeuge und Schienen im Hängebahnbereich geeignet.This vehicle is particularly suitable for use in cross-section I-shaped rails that are held on supports on the floor. This transport system is therefore suitable for bypassing mostly in the floor plan right-angled warehouses for general cargo from the individual storage locations record or deliver to them. The invention is also for vehicles and Rails suitable in the monorail area.
