Description

Die Erfindung betrifft einen Wagen für Schienensysteme mit im wesentlichen rechtwinkligen Schienenkreuzen, mit anhebbaren und absenkbaren Rollen an dem Wagen für einen alternativen Eingriff mit jeweils einem der sich kreuzenden Schienenpaare.The invention relates essentially to a carriage for rail systems right-angled rail crosses, with raisable and lowerable castors the trolley for an alternative intervention with one of the intersecting ones Rail pairs.

Die Erfindung ist insbesondere anwendbar auf Schienensysteme mit im Querschnitt kreisförmig, weitgehend in den Boden eingelassenen Schienen, wie sie in den DE 43 18 383 CI oder FR-A-1 484 615 beschrieben worden sind. Derartige Schienensysteme können beispielsweise in einer Werkshalle verlegt werden, ohne daß sie ein nennenswertes Hindernis beim Begehen oder Befahren des Hallenbodens darstellen. Sie ermöglichen im übrigen auch die Aufnahme sehr hoher Tragkräfte, so daß sie sich besonders eignen für Transportaufgaben in Industriehallen.The invention is particularly applicable to rail systems with a cross-section circular, largely recessed rails, as in DE 43 18 383 CI or FR-A-1 484 615 have been described. Such rail systems can For example, be installed in a factory hall without it being worth mentioning Show obstacles when walking or driving on the hall floor. They also allow the absorption of very high capacities, so that they are particularly suitable for transport tasks in industrial halls.

Zur weitgehenden Erschließung der gesamten Hallenfläche ist es zumeist erforderlich, die Schienen in einem Raster mit rechtwinkligen Kreuzungen zu verlegen. Dabei läßt sich der Übergang von einem Schienenpaar zu einem anderen rechtwinklig kreuzenden Schienenpaar dadurch erreichen, daß die dem ersten Schienenpaar zugeordneten Rollen angehoben und zugleich die dem kreuzenden Schienenpaar zugeordneten Rollen des Wagens in Bezug auf den Wagen abgesenkt werden. Auf diese Weise kommen nur die dem kreuzenden Schienenpaar zugeordneten Rollen mit diesen Schienen in Eingriff. Da der erwähnte Umschaltvorgang unter Umständen bei hoher oder sehr hoher Belastung erfolgen muß, hat es sich als schwierig erwiesen, eine verschleißfeste, dauerhaft haltbare und trotzdem möglichst einfache Umschaltvorrichtung zu schaffen, die es ermöglicht, die Umschaltung möglichst rasch vorzunehmen.To open up the entire hall area to a large extent, it is usually necessary to lay the rails in a grid with right-angled crossings. This allows the transition from one pair of rails to another achieve a pair of rails crossing at right angles by moving the first Rails assigned to the pair of rails raised and at the same time the crossing The pair of rails associated with the rollers of the carriage are lowered with respect to the carriage become. In this way, only the crossing pair of rails come assigned roles with these rails in engagement. Since the switching process mentioned may have to take place at high or very high loads, It has proven difficult to find a wear-resistant, durable and durable nevertheless to create the simplest possible switching device which enables make the switch as quickly as possible.

Der Erfindung liegt daher die Aufgabe zugrunde, einen Wagen der eingangs genannten Art mit einer Umschaltvorrichtung für die Rollen zu schaffen, die es gestattet, die Rollen im wesentlichen gleichzeitig und mit relativ geringem Kraftaufwand anzuheben beziehungsweise abzusenken.The invention is therefore based on the object of a carriage of the type mentioned Type with a switching device for the roles that allows to the rollers essentially simultaneously and with relatively little effort raise or lower.

Diese Aufgabe wird erfindungsgemäß durch einen Wagen der obigen Art gelöst, der dadurch gekennzeichnet ist, daß ein Stellantrieb vorgesehen ist, der zugleich die mit einem Schienenpaar zusammenwirkende Rollen in bezug auf den Wagen anhebt und die mit dem kreuzenden Schienenpaar zusammenwirkendenden Rollen in bezug auf den Wagen absenkt. According to the invention, this object is achieved by a carriage of the above type, which is characterized in that an actuator is provided, which at the same time the rollers cooperating with a pair of rails in relation to the carriage lifts and those interacting with the crossing pair of rails Rolls lowered with respect to the carriage.

Das erfindungsgemäße Umschaltsystem umfaßt somit nur einen Stellantrieb, etwa einen Hydraulikzylinder, einen Spindeltrieb oder dergleichen.The switching system according to the invention thus comprises only one actuator, such as a hydraulic cylinder, a spindle drive or the like.

An den Wagen der hier interessierenden Art sind zumeist in einer insgesamt quadratischen Anordnung an allen vier Seiten jeweils in der Nähe der Enden dieser Seiten Rollen oder auch Rollengruppen mit zwei oder drei Rollen vorgesehen.On the cars of the type of interest here are mostly in one square arrangement on all four sides near the ends this page roles or role groups with two or three roles are provided.

Erfindungsgemäß sind diese Rollen oder Rollengruppen vorzugsweise mit Hilfe von Lenkern an der Unterseite des Wagens gelagert, und zwar derart, daß ein Zug oder Schub in Richtung entlang den jeweiligen Seitenrändern zu einer Schwenkung der Lenker und dabei zu einer Anhebung oder Absenkung der Rollen oder Rollengruppen führt. Das bedeutet, daß die Höhenverstellung der Rollen oder Rollengruppen durch geeignete Ausübung von Schub und Zug auf die Rollengruppen, etwa von einer Position in der Mitte der jeweiligen seitlichen Ränder aus erfolgen kann.According to the invention, these roles or role groups are preferably assisted mounted by handlebars on the underside of the car, in such a way that a Pull or push in the direction along the respective side edges to one Swiveling the handlebars and thereby raising or lowering the rollers or role groups. This means that the height adjustment of the rollers or role groups through appropriate exercise of push and pull on the Role groups, for example from a position in the middle of the respective side Edges can be made.

Der zentrale Stellantrieb wirkt vorzugsweise auf zwei einander kreuzende, am Wagen gelagerte, über Kegeltriebe gekoppelte Wellen ein, die sich jeweils von Seitenmitte zu Seitenmitte erstrecken, also zwischen den beiden Rollen oder Rollengruppen an den vier Seiten des Umrisses des Wagens enden. An diesen Enden sind vorzugsweise Doppelhebel befestigt, die mit jeweils einem ihrer Enden schwenkbar mit einer Stange verbunden sind, die am anderen Ende schwenkbar mit einer Rolle oder Rollengruppe in Verbindung steht. Durch Drehung der Wellen und entsprechende Schwenkung der Doppelhebel kann über die Stangen in Richtung der Rollen oder Rollengruppen Zug oder Schub ausgeübt werden. Durch Zug oder Schub werden die Rollen, die wie erwähnt, mit Hilfe von Lenkern schwenkbar am Wagen gelagert sind, in Bezug auf den Wagen abgesenkt oder angehoben.The central actuator preferably acts on two intersecting, on Carriage-mounted shafts coupled via bevel drives, each of which shifts from Extend the middle of the page to the middle of the page, i.e. between the two roles or role groups end on the four sides of the outline of the car. At these ends double levers are preferably attached, each with one of its ends are pivotally connected to a rod which is pivotable at the other end associated with a role or role group. By rotating the waves and corresponding swiveling of the double lever can be done via the rods Direction of roles or groups of roles train or push can be exercised. By pulling or pushing the roles, as mentioned, with the help of handlebars are pivotally mounted on the carriage, lowered with respect to the carriage or raised.

Vorzugsweise ist die Zuordnung der Lenker der Rollen oder Rollengruppen und der Doppelhebel der Wellen derart, daß bei abgesenkten Rollen oder Rollengruppen die Lenker senkrecht nach unten zeigen und die Doppelhebel waagerecht stehen. Auf diese Weise werden die Lenker durch nach oben gerichteten Schub entlang ihrer Längsrichtung belastet, und mögliche seitliche Ausweichkräfte, die unter hoher Belastung auf die Lenker einwirken können, werden durch die Doppelhebel in ihrer Längsrichtung aufgenommen. Beide Belastungsrichtungen sind kinematisch äußerst vorteilhaft, und insbesondere wird im wesentlichen verhindert, daß der Antrieb insgesamt mit dem Wellensystem ein nennenswertes Haltemoment ausüben muß, um die Belastung der abgesenkten Rollen aufzunehmen. Die genannte Anordnung der Lenker und der Doppelhebel hat noch einen weiteren Vorteil. Das beruht darauf, daß die zwischen den Doppelhebeln und den Rollen oder Rollengruppen angeordneten Stangen nicht linear verschoben werden, sondern Kreisbewegungen folgen. Aufgrund der genannten Anordnung ist die waagerechte Komponente der Stangen beim Absenken der Rollen oder Rollengruppen auf die Schienen am Anfang der Absenkbewegung relativ groß, während die waagerechte Komponente im weiteren Verlauf der Drehung der Doppelhebel immer geringer wird. Andererseits ist die vertikale Komponente der Rollen oder Rollengruppen am Anfang der Rollengruppen oder Rollen ebenfalls verhältnismäßig groß, während sie zum Ende der Absenkbewegung hin immer mehr abnimmt. Daraus ergibt es sich, daß beim Wechsel der Rollen oder Rollengruppen die Absenkbewegung der Rollen für eines der Schienenpaare der Anhebbewegung der Rollen des anderen Schienenpaares vorauseilt. Der Wagen wird daher relativ rasch durch die neuen Rollen abgestützt, so daß er beim Rollenwechsel nicht wesentlich absinkt. Ein erneutes Anheben nach dem Absinken würde bei schwerer Beladung des Wagens hohe Kräfte und eine entsprechende Dimensionierung des Stellantriebs erfordern.The assignment of the handlebars to the roles or role groups is preferably the double lever of the shafts in such a way that with lowered rollers or roller groups the handlebars point vertically downwards and the double levers horizontally stand. In this way, the handlebars are pushed upwards along their longitudinal direction, and possible lateral evasive forces that can act on the handlebars under high load by the double lever taken in their longitudinal direction. Both load directions are extremely advantageous kinematically, and in particular it essentially prevents that the drive overall with the shaft system a significant holding torque must exercise to absorb the load on the lowered rollers. The arrangement of the handlebars and the double lever mentioned has yet another Advantage. This is due to the fact that the between the double levers and Rods or groups of rollers arranged in a row cannot be moved linearly, but follow circular movements. Because of the arrangement mentioned the horizontal component of the bars when lowering the rolls or roll groups relatively large on the rails at the start of the lowering movement the horizontal component as the double lever continues to rotate is getting lower. On the other hand, the vertical component of the roles or role groups at the beginning of the role groups or roles are also proportionate large as it continues to move towards the end of the lowering movement decreases. This means that when changing roles or role groups the lowering movement of the rollers for one of the pairs of rails of the lifting movement ahead of the roles of the other pair of rails. The car is therefore supported relatively quickly by the new roles, so that it when changing roles does not sink significantly. A further raise after the sink would when the wagon is heavily loaded, high forces and appropriate dimensioning of the actuator.

In Fig. 1 ist ein Wagen insgesamt mit 10 bezeichnet. Er bildet eine im wesentlichen quadratische Plattform, ist jedoch in der Zeichnung nur in seinen Umrissen angedeutet, da es im folgenden ausschließlich auf die unterhalb des Wagens angeordneten, umschaltbaren Rollen ankommt. Zwei einander kreuzende Schienenpaare sind in der Zeichnung mit 12,14 und 16,18 bezeichnet. In Fig. 1 sind die Schienen nur als strichpunktierte Linien angedeutet. Auf den Schienen 12 und 14 befinden sich gemäß Fig. 1 jeweils zwei Rollengruppen 20,22 und 24,26 mit jeweils zwei nicht gesondert bezeichneten Rollen. Die Rollenpaare liegen an den einzelnen Seiten in Abstand zueinander in der Nähe der Ecken des Wagens.In Fig. 1, a car is designated 10 in total. It essentially forms one square platform, however, is only in its outline in the drawing hinted, as it only refers to the below the car Arranged, switchable roles arrives. Two pairs of rails crossing each other are designated in the drawing with 12.14 and 16.18. 1 are the rails are only indicated as dash-dotted lines. On the rails 12 1 and 14 there are two role groups 20, 22 and 24, 26 according to FIG each with two roles not specifically identified. The roller pairs are in contact the individual sides spaced apart near the corners of the car.

Auf den in Fig. 1 oben und unten liegenden Seiten befinden sich auf den Schienen 16,18 in entsprechender Weise Rollenpaare 28,30 und 32,34, die ebenfalls zwei hintereinanderliegende, nicht gesondert bezeichnete Rollen umfassen. Die Rollen der einzelnen Rollengruppen sind in Rollenträgern 36,38,40,42 und 44,46,48,50 gelagert. Diese Rollenträger 36,...,50 sind beidseitig mit Hilfe von-Lenkern 52,54 (Fig. 4) an einem nicht näher dargestellten festen Konstruktionsteil 56 des Wagens aufgehängt. Die isometrische Darstellung gemäß Fig. 4 bezieht sich auf die rechte untere Ecke des Wagens 10 in Fig. 1. Während die Lenker 52,54 des Rollenträgers 42 der Rollengruppe 26 rechts unten in Fig. 4 eine geneigte Stellung einnehmen, sind die entsprechenden Lenker 58,60 der links in Fig. 4 gezeigten Rollengruppe 32 senkrecht nach unten gerichtet. Diese geringe Schwenkbewegung der Lenker hat zur Folge, daß die links gezeigte Rollengruppe 32 fest auf der Schiene 18 liegt, während die Rollengruppe 26 auf der rechten Seite in Fig. 4 von der Schiene 14 abgehoben ist.On the top and bottom sides in Fig. 1 are on the rails 16, 18 in a corresponding manner, pairs of rolls 28, 30 and 32, 34, which are also comprise two successive, not separately designated roles. The Roles of the individual role groups are in role carriers 36, 38, 40, 42 and 44,46,48,50 stored. These roller carriers 36, ..., 50 are on both sides with the help of handlebars 52,54 (Fig. 4) on a solid structural part, not shown 56 of the car hung. The isometric representation according to FIG. 4 relates on the lower right corner of the cart 10 in Fig. 1. While the handlebars 52, 54 of the roller carrier 42 of the roller group 26 at the bottom right in FIG assume inclined position, the corresponding handlebars 58, 60 are on the left in Fig. 4 shown roller group 32 directed vertically downwards. This minor Swiveling movement of the handlebars has the consequence that the roller group shown on the left 32 is firmly on the rail 18, while the roller group 26 on the right 4 is lifted off the rail 14.

Wie Fig. 4 exemplarisch zeigt, sind die beiden Rollenträger 42 und 48 über Stangen 62 und 64, die einerseits schwenkbar an den Rollenträgern und andererseits schwenkbar an einem Ende der Doppelhebel 66,68 gelagert sind, waagerecht verschiebbar.As an example in FIG. 4, the two roller carriers 42 and 48 are over rods 62 and 64, which are pivotable on the one hand on the roller carriers and on the other are pivotally mounted at one end of the double lever 66,68, horizontally displaceable.

Die Doppelhebel 66,68 sind auf den Enden von Wellen 70,72 befestigt, die sich in einem Kegelgetriebe 74 im Mittelpunkt des Wagens 10 kreuzen und insgesamt die Fläche des Wagens in vier gleiche Quadrate teilen. Die Wellen 70 und 72 sind mit Hilfe des Kegelgetriebes synchron verbunden.The double levers 66, 68 are fastened on the ends of shafts 70, 72, which are themselves cross in a bevel gear 74 in the center of the carriage 10 and total divide the area of the car into four equal squares. Waves 70 and 72 are connected synchronously with the help of the bevel gear.

Als zentraler Stellantrieb ist ein Hydraulikzylinder 76 vorgesehen, dessen Kolben stange 78 mit dem freien Ende eines Hebels 80 zusammenwirkt, der fest auf der Welle 70 angebracht ist. Die Kolbenbewegung des Hydraulikzylinders 76 ermöglicht damit eine Drehung der Welle 70 und zugleich über das Kegelgetriebe 74 der anderen Welle 72. Da die beiden Doppelhebel 68 an den Enden der Welle 72 senkrecht und die beiden Doppelhebel 66 an den Enden der Welle 70 waagerecht stehen, werden die Rollenträger 44,46 und 48,50 angehoben und die Rollenträger 36,38,40,42 abgesenkt. Der Hydraulikzylinder 76 ist mit Hilfe von zwei Leitungen 82,84 mit einem Zweiwegeventil 86 verbunden, das den Ölstrom von einer Hydraulikpumpe 88 in beiden Richtungen dem Hydraulikzylinder 76 zuführen kann.A hydraulic cylinder 76, the piston of which is provided as the central actuator rod 78 cooperates with the free end of a lever 80 which is firmly on the Shaft 70 is attached. The piston movement of the hydraulic cylinder 76 enables thus a rotation of the shaft 70 and at the same time via the bevel gear 74 the other shaft 72. Since the two double levers 68 at the ends of the shaft 72 vertically and the two double levers 66 at the ends of the shaft 70 horizontally stand, the roller carriers 44,46 and 48,50 are raised and the Roller carrier 36,38,40,42 lowered. The hydraulic cylinder 76 is by means of two lines 82, 84 connected to a two-way valve 86, which the oil flow from a hydraulic pump 88 in both directions to the hydraulic cylinder 76 can feed.

Die Anwendung der Erfindung ist nicht beschränkt auf im Querschnitt kreisrunde Schienen und ausgekehlte Laufrollen, wie sie in der Zeichnung gezeigt sind.The application of the invention is not limited to circular in cross section Rails and grooved casters as shown in the drawing are.

Der erfindungsgemäße Wagen eignet sich insbesondere für eine Steuerung vom Hallenboden aus. So können beispielsweise in den Zentren der Kreuzungen drehbare Stellglieder in den Hallenboden eingelassen sein, die mit Eingriffsgliedern an der Unterseite der Wagen in Eingriff treten können, wenn sich ein Wagen über einer Kreuzung befindet. Auf diese Weise können vom Hallenboden aus beispielsweise die Rollengruppen 20,22,24,26 an zwei paralellen Seiten eines Wagens abgesenkt und die Rollengruppen 28,30,32,34 an den beiden anderen paralellen Rändern eines Wagens angehoben werden, so daß der Wagen seine Laufrichtung um 90° ändert.The car according to the invention is particularly suitable for controlling the Hall floor. For example, in the centers of the intersections rotatable actuators can be embedded in the hall floor, with engagement elements can engage at the bottom of the cart when there is a cart located above an intersection. In this way you can start from the hall floor For example, the role groups 20, 22, 24, 26 on two parallel sides of one Car lowered and the role groups 28,30,32,34 on the other two parallel edges of a car can be raised so that the car has its Running direction changes by 90 °.

Wie dies geschehen kann, ist in Fig. 5 und Fig. 6 schematisch angedeutet.How this can be done is indicated schematically in FIGS. 5 and 6.

Anstelle der drei miteinander kämmenden Kegelräder des Kegelgetriebes 74 der zuvor beschriebenen Ausführungsform ist ein an der Unterseite des Wagens, um eine senkrechte Achse drehbares Kegelrad 90 gelagert. Dieses Kegelrad 90 weist an seiner Unterseite ein Eingriffsglied 92 auf, das wiederum an seiner Unterseite ein Eingriffsprofil 94, etwa in der Form eines Schraubenschlitzes besitzt. Im Boden 96 der Halle, befinden sich ein Drehantrieb 98, der in der Lage ist, ein Stellglied 100, das etwa die Form einer Schraubenzieherklinge besitzen kann, um 90° in beide Richtungen zu drehen.Instead of the three intermeshing bevel gears of the bevel gear 74 of the The previously described embodiment is one at the bottom of the cart a vertical axis rotatable bevel gear 90 is mounted. This bevel gear 90 has on its underside an engaging member 92, which in turn on its underside has an engagement profile 94, approximately in the form of a screw slot. In the ground 96 of the hall, there is a rotary drive 98, which is capable of an actuator 100, which may have the shape of a screwdriver blade, um Turn 90 ° in both directions.

Die Form des Eingriffsglieds 92 und des Stellglieds 100 kann anders ausgebildet sein, sollte jedoch die Begeh- oder Befahrbarkeit des Hallenbodens im allgemeinen nicht stören. Wenn ein Wagen auf eine Kreuzung fährt, tritt das Stellglied 100 in den Schlitz des Eingriffsprofils 94 ein. Wenn nunmehr ein Drehimpuls an den Drehantrieb 98 gegeben wird, kann das Kegelrad 90 um 90° gedreht werden. In das Kegelrad greifen von vier Seiten Kegelräder 102,104,106 ein, die auf Wellen 70,72 befestigt sind, die hier in beiden einander kreuzenden Richtungen als geteilte Halbwellen ausgebildet sind. Diese Kegelräder 102,104,106 kämmen mit dem waagerechten Kegelrad 90. Sie stehen untereinander im Gegensatz zu der ersten Ausführungsform nicht in Eingriff. Sie drehen sich also gleichsinnig, und nicht wie bei der ersten Ausführungsform gegensinnig. Dies muß bei der Anordnung der nachfolgenden Stellmechanismen berücksichtigt werden.The shape of the engaging member 92 and the actuator 100 may be different should, however, be the ability to walk or drive on the hall floor in general do not bother. When a car goes to an intersection, the actuator kicks in 100 into the slot of the engagement profile 94. If now there is an angular momentum the rotary drive 98 is given, the bevel gear 90 can be rotated 90 °. Bevel gears 102, 104, 106 engage the bevel gear from four sides Shafts 70, 72 are attached here in both intersecting directions are designed as split half-waves. Comb these bevel gears 102, 104, 106 with the horizontal bevel gear 90. They are opposed to each other the first embodiment does not engage. So you turn in the same direction, and not in opposite directions as in the first embodiment. This must be the case with the Arrangement of the following adjusting mechanisms are taken into account.

Es ist daher nicht erforderlich, jeden einzelnen Wagen zu Zwecken der Fernsteuerung innerhalb einer Halle mit einem eigenen Sende- und Empfangssystem oder dergleichen auszurüsten, da die Steuerung der Wagen über einen im Hallenboden verlegtes Stellsystem erfolgen kann.It is therefore not necessary to use each individual cart for remote control purposes within a hall with its own transmission and reception system or equip the like, since the control of the car via one in the hall floor installed control system can take place.

Fig. 6 bezieht sich ebenfalls auf die in Fig. 5 dargestellte Ausführungsform, unterscheidet sich jedoch von der Variante gemäß Fig. 5 dadurch, daß nicht vier Halbwellen, sondern eine durchgehende Welle 70 und zwei Halbwellen 72 vorgesehen sind, die die Drehung der Kegelräder 102,104,106 auf die Umschaltmechanismen übertragen, wie es bereits bei der ersten Ausführungsform der Fall war. In jedem Fall sind die nachgestellten Elemente der Umschaltmechanismen der Drehrichtung der Kegelräder anzupassen.Fig. 6 also relates to the embodiment shown in Fig. 5, differs 5, however, that not four Half waves, but a continuous wave 70 and two half waves 72 are provided are the rotation of the bevel gears 102,104,106 on the switching mechanisms transferred, as is already the case with the first embodiment was. In any case, the trailing elements of the switching mechanisms to adapt to the direction of rotation of the bevel gears.
