Abstract

A switch control for a self-propelled floor transportation vehicle is known, which has a guide shoe which engages in a guide rail. The guide shoe can be laterally displaced with respect to the travel direction so that a desired travel direction can be selected at a fork. The known switch control operates with electromagnets which are arranged on the floor area and act on the guide shoe. If the electromagnet is activated, this leads to the guide shoe swivelling. However, the use of electromagnets in the floor area requires a high degree of expenditure. Therefore, it is proposed to provide fork signalling elements in the floor area, which elements are evaluated via sensor elements in the floor transportation vehicle and actuate drive units for the guide shoe.

Description

Die Erfindung betrifft eine Weichensteuerung für ein selbstfahrendes Bodenfördererfahrzeug, das einen Führungsschuh aufweist. Der Führungsschuh greift in eine Führungsschiene am Boden ein, weshalb das Bodenfördererfahrzeug zwangsgeführt wird. Der Führungsschuh ist so gelagert, daß, bezogen auf die Fahrtrichtung, ein seitliches Verlagern möglich ist. Mittels des seitlich verlagerbaren Führungsschuhs kann in Gabelungsbereichen der Führungsschiene die gewünschte Fahrtrichtung für das Bodenfördererfahrzeug bestimmt werden.The invention relates to a switch control for a self-propelled floor conveyor vehicle that has a guide shoe. The guide shoe engages in a guide rail on the ground, which is why the floor conveyor vehicle is positively guided. The guide shoe is mounted in such a way that it can be moved sideways in relation to the direction of travel. By means of the laterally displaceable guide shoe, the desired direction of travel for the floor conveyor vehicle can be determined in the forked areas of the guide rail.

Es ist bekannt, den Führungsschuh durch Elektromagnete zu verlagern, die an einer Gabelung neben der Führungsschiene ausgebildet sind. Dazu werden die Elektromagnete angesteuert, wenn das Bodenfördererfahrzeug sich dem Gabelungsbereich nähert. Das Ausbilden von Elektromagneten mit den zugehörigen Vesorgungsleitungen in den Gabelungsbereichen erweist sich mitunter als aufwendig, wenn beispielsweise andere Maschinen ortsfest im Gabelungsbereich angeordnet sind.It is known to displace the guide shoe by means of electromagnets which are formed on a fork next to the guide rail. For this purpose, the electromagnets are activated when the ground conveyor vehicle approaches the fork area. The formation of electromagnets with the associated supply lines in the fork areas sometimes proves to be complex if, for example, other machines are arranged in a fixed position in the fork area.

Es ist deshalb Aufgabe der Erfindung, eine Weichensteuerung für ein selbstfahrendes Bodenfördererfahrzeug zu schaffen, die in den Gabelungsbereichen in einfacher Weise ausbildbar ist.It is therefore an object of the invention to provide a switch control for a self-propelled ground conveyor vehicle which can be formed in a simple manner in the fork regions.

Die Aufgabe der Erfindung wird durch die Merkmale des kennzeichnenden Teils des Patentanspruchs 1 gelöst.The object of the invention is achieved by the features of the characterizing part of patent claim 1.

Nach der Erfindung werden im Bereich einer Gabelung Gabelungssignalelemente vorgesehen, die, bezogen auf die Fahrtrichtung eines Bodenfördererfahrzeuges, der Gabelung vorgelagert sind. Die Gabelungssignalelemente werden durch Sensorelemente abgetastet, die an dem Bodenfördererfahrzeug ausgebildet sind. D.h. erfindungsgemäß signalisieren die Gabelungssignalelemente dem Bodenfördererfahrzeug das Annähern an eine Gabelung und das Ansteuern eines Führungsschuhes über Antriebseinheiten wird zum Bestimmen der Fahrtrichtung in dem Bodenfördererfahrzeug selbst vorgenommen.According to the invention, fork signal elements are provided in the area of a fork, which are upstream of the fork in relation to the direction of travel of a floor conveyor vehicle. The fork signal elements are sensed by sensor elements formed on the ground conveyor vehicle. I.e. According to the invention, the fork signaling elements signal the ground conveyor vehicle to approach a fork and to control a guide shoe via drive units to determine the direction of travel in the ground conveyor vehicle itself.

Erfindungsgemäß ergibt sich damit der Vorteil, daß nur so viele Steuermechanismen wie Bodenfördererfahrzeuge vorzusehen sind. Dies wirkt sich insbesondere bei großen Fahrtstrecken mit vielen Gabelungen aus, da als Gabelungssignalelemente z.B. nur aufklebbare Markierungen erforderlich sind. Die Gabelungssignalelemente sind folglich leicht anzubringen, zu verändern oder zu variieren. Zusätzlich erfordern die Gabelungssignalelemente keinen großen Platzbedarf.According to the invention, there is the advantage that only as many control mechanisms as floor conveyor vehicles are to be provided. This has an effect in particular on long journeys with a large number of forks, since, for example, only markings that can be stuck on as fork signal elements required are. The fork signal elements are consequently easy to attach, change or vary. In addition, the fork signal elements do not require much space.

Nach der Erfindung sind optisch, induktiv oder kapazitiv wirkende Sensorelemente vorsehbar, die auf die entsprechenden Signale der Gabelungssignalelemente ansprechen. Folglich ergibt sich ein großer Anwendungsbereich, da auf die verschiedensten Sensorelemente und Gabelungssignalelemente zurückgegriffen werden kann. Der mechanische Steuerungsmechanismus in dem Bodenfördererfahrzeug kann hierbei unverändert bleiben.According to the invention, optically, inductively or capacitively acting sensor elements can be provided which respond to the corresponding signals of the fork signal elements. This results in a wide range of applications, since a wide variety of sensor elements and fork signal elements can be used. The mechanical control mechanism in the floor conveyor vehicle can remain unchanged.

Werden die Gabelungssignalelemente vor und hinter der Gabelung angebracht, läßt sich dem Bodenfördererfahrzeug in einfacher Weise signalisieren, daß der Gabelungsbereich durchlaufen wurde. Das am Ende der Gabelung angeordnete Gabelungssignalelement signalisiert, daß der Führungsschuh in die Ruheposition zurückgestellt werden kann.If the fork signal elements are attached in front of and behind the fork, the ground conveyor vehicle can be signaled in a simple manner that the fork region has been passed through. The fork signal element located at the end of the fork signals that the guide shoe can be returned to the rest position.

Ist die Antriebseinheit über eine Schub- und Zugstange mit dem Führungsschuh verbunden, ergibt sich ein einfacher mechanischer Aufbau, wobei zusätzlich eine Rückstellfeder vorgesehen sein kann, die den Führungsschuh nach dem Durchlaufen des Gabelungsbereiches in die Ruheposition bringt. Die Rückstellfeder verringert die Mittel, den Führungsschuh in die Ruheposition zurückzusetzen. Hierzu ist es nur erforderlich, die Antriebseinheit, bei der es sich beispielsweise um einen Hubmagneten, Spindelmotor oder Linearmotor handelt, nicht weiter mit Antriebsenergie zu versorgen. Das Rückstellen erfolgt dann selbsttätig.If the drive unit is connected to the guide shoe via a push and pull rod, the result is a simple mechanical construction, in which case a return spring can also be provided, which brings the guide shoe into the rest position after passing through the fork area. The return spring reduces the means to return the guide shoe to the rest position. For this purpose, it is only necessary to no longer supply the drive unit, which is, for example, a lifting magnet, spindle motor or linear motor, with drive energy. The resetting then takes place automatically.

Wird eine Halteeinrichtung vorgesehen, die den verschwenkten Führungsschuh für die Zeitdauer arretiert, damit das Bodenfördererfahrzeug sicher die gewünschte Fahrtrichtung einnimmt, werden Fehlsteuerungen vermieden, die das Bodenfördererfahrzeug in eine falsche Richtung lenken. Die Halteeinrichtung kann mit den Gabelungssignalelementen zusammenwirken, die am Ende der Gabelung ausgebildet sind. Hierdurch läßt sich in einfacher Weise die Freigabe der Halteeinrichtung steuern. Die Halteeinrichtung kann platzsparend aufgebaut werden, wenn es sich hierbei um ein elektronisches Zeitglied handelt.If a holding device is provided which locks the pivoted guide shoe for the period of time so that the floor conveyor vehicle assumes the desired direction of travel, incorrect controls are avoided which steer the floor conveyor vehicle in the wrong direction. The holding device can interact with the fork signal elements which are formed at the end of the fork. In this way, the release of the holding device can be controlled in a simple manner. The holding device can be constructed in a space-saving manner if it is an electronic timer.

Wird erfindungsgemäß eine Speichereinrichtung vorgesehen, die die Antriebseinheiten für den Führungsschuh ansteuert, läßt sich anhand der Anzahl von Gabelungssignalelementen eine Kursvorgabe an dem Bodenfördererfahrzeug selbst einprogrammieren. Die Speichereinrichtung vergleicht hierzu die Signale, die von den Sensorelementen detektiert werden mit den entsprechend der Kursvorgabe eingespeicherten Werten. Beispielsweise signalisiert das dritte Gabelungssignalelement der Speichereinrichtung, daß das Bodenfördererfahrzeug in eine rechte Fahrspur umgelenkt werden soll.If, according to the invention, a storage device is provided which controls the drive units for the guide shoe, a course specification on the ground conveyor vehicle itself can be programmed on the basis of the number of fork signal elements. For this purpose, the memory device compares the signals which are detected by the sensor elements with the values stored in accordance with the course specification. For example, the third fork signal element of the storage device signals that the ground conveyor vehicle should be deflected into a right lane.

In Fig. 1 ist ein Bodenfördererfahrzeug 1 schematisch in Draufsicht dargestellt, das sich einer Gabelung 3 einer Führungsschiene 2 nähert. Die Führungsschiene 2, bei der es sich z.B. um eine Unterflur-Führungsschiene handelt, gabelt sich nach Fig. 1 in eine rechte Fahrbahn 4 und eine linke Fahrbahn 5. Beidseitig zu der Führungsschiene 2 sind Gabelungssignalelemente 8 vorgesehen, die dem Fahrzeug 1 das Annähern an die Gabelung 3 signalisieren. Die Gabelungssignalelemente 8 können unterschiedliche Informationen tragen und beispielsweise anzeigen, um welche Fahrbahn 4, 5 es sich handelt. Je nach Anwendungsfall reicht auch ein Signalelement 8 aus, die Steuerung der Fahrtrichtung des Fahrzeuges 1 zu veranlassen. Beispielsweise kann es sich bei den Signalelementen 8 um aufgeklebte Magnetstreifen, optisch oder kapazitiv wirkende Markierungen handeln.In Fig. 1, a floor conveyor vehicle 1 is shown schematically in plan view, which approaches a fork 3 of a guide rail 2. The guide rail 2, which is e.g. 1 is a right-hand carriageway 4 and a left-hand carriageway 5, fork signals signal elements 8 are provided on both sides of the guide rail 2, which signal the vehicle 1 that it is approaching the fork 3. The fork signal elements 8 can carry different information and, for example, indicate which lane 4, 5 it is. Depending on the application, a signal element 8 is also sufficient to cause the direction of travel of the vehicle 1 to be controlled. For example, the signal elements 8 can be glued-on magnetic strips, optically or capacitively acting markings.

Signalelemente 8 werden durch Sensorelemente 9 detektiert, die in dem Fahrzeug 1 selbst angeordnet sind und folglich parallel zu der Führungsschiene 2 mitbewegt werden. Sobald die Sensorelemente 9 ein Signalelement 8 detektieren, gelangt ein Signal zu der Steuerung 11, die das detektierte Signal auswertet. Die Steuerung 11 betätigt Antriebseinheiten 10, die auf einen Führungsschuh 6 einwirken. Nach Fig. 1 ist der Führungsschuh 6 in einem Drehpunkt 7, bezogen auf die Fahrtrichtung, seitlich verschwenkbar gelagert. Bevorzugt ist das vordere Ende des Führungsschuhs 6 zu einer Spitze 13 geformt. Der Führungsschuh 6 mit der Spitze 13 bewirkt, daß das Fahrzeug 1 in der Führungsschiene 2 zwangsgeführt wird. In den Bereichen der Gabelung 3 bewirkt der Führungsschuh 6 zusätzlich nach dem Verschwenken, daß der Führungsschuh selbst in die gewünschte Fahrbahn 4, 5 eingleitet. Ist beispielsweise nur ein Signalelement 8 vorgesehen und die Steuerung 11 dahingehend ausgelegt, daß das Vorhandensein eines Signalelementes 8 einem Abzweigen in die rechte Fahrbahn 4 entspricht, so wird der Führungsschuh 6 durch die Antriebseinheiten 10 in Fig. 1 nach rechts im Uhrzeigersinn verschwenkt, wenn das Sensorelement 9 das Signalelement 8 detektiert. Ist kein Signalelement 8 vorgesehen, verbleibt der in Fig. 1 gezeigte Führungsschuh 6 in seiner Position, weshalb das Fahrzeug 1 in die geradlinige Fahrbahn 5 einfährt. Je nach Anwendungsfall sind auch mehrere Signalelemente 8 vorsehbar, wenn die Gabelung 3 mehrere Abzweigungen aufweist. Durch die Wahl der Sensorelemente 8, die die Position der Spitze 13 des Führungsschuhs 6 bestimmen, läßt sich jede von mehreren Fahrbahnen sicher kennzeichnen. In dem Fahrzeug 1 kann zusätzlich eine Speichereinrichtung 12 vorgesehen sein, in der eine Kursvorgabe einprogrammiert ist. Die Steuerung 11 wertet hierzu die von den Sensorelementen 9 abgegebenen Eingangswerte aus und vergleicht sie mit den abgespeicherten Werten. Hierzu können die Signalelemente 8 Informationen tragen, um welche Gabelung 3 es sich handelt. Zusammen mit den abgespeicherten Informationen läßt sich so die Fahrtroute des Fahrzeuges 1 festlegen.Signal elements 8 are detected by sensor elements 9, which are arranged in the vehicle 1 itself and are consequently moved parallel to the guide rail 2. As soon as the sensor elements 9 detect a signal element 8, a signal reaches the controller 11, which evaluates the detected signal. The controller 11 actuates drive units 10 which act on a guide shoe 6. 1, the guide shoe 6 is pivotally mounted laterally at a pivot point 7, based on the direction of travel. The front end of the guide shoe 6 is preferably shaped into a tip 13. The guide shoe 6 with the tip 13 causes the vehicle 1 to be positively guided in the guide rail 2. In the areas of the fork 3, the guide shoe 6 additionally causes after pivoting that the guide shoe itself slides into the desired roadway 4, 5. Is For example, only one signal element 8 is provided and the control 11 is designed such that the presence of a signal element 8 corresponds to a branching off into the right-hand lane 4, the guide shoe 6 is pivoted clockwise by the drive units 10 in FIG. 1 when the sensor element 9 detects the signal element 8. If no signal element 8 is provided, the guide shoe 6 shown in FIG. 1 remains in its position, which is why the vehicle 1 enters the straight-line lane 5. Depending on the application, several signal elements 8 can also be provided if the fork 3 has several branches. The choice of the sensor elements 8, which determine the position of the tip 13 of the guide shoe 6, makes it possible to reliably mark each of a plurality of lanes. A storage device 12 can also be provided in the vehicle 1, in which a course specification is programmed. For this purpose, the controller 11 evaluates the input values output by the sensor elements 9 and compares them with the stored values. For this purpose, the signal elements 8 can carry information as to which fork 3 it is. The route of the vehicle 1 can thus be determined together with the stored information.

In den Figuren 2 und 3 ist das Fahrzeug 1 zur vereinfachten Darstellung nicht vollständig abgebildet. Ziffer 2 zeigt eine Seitenansicht auf die Antriebseinheiten 10, die über eine Schub- und Zugstange 16 an dem Führungsschuh 6 angreifen. Der Führungsschuh 6, der in Fig. 2 in einer im Boden 18 eingelassenen Führungsschiene 2 gleitet, ist über eine Achse 14 und einen Ansatz 15 mit den Schub- und Zugstangen 16 verbunden. Die Antriebseinheiten 10 sind beidseitig zu dem Führungsschuh 6 angeordnet, weshalb sich ein symmetrischer Aufbau ergibt. Zwei Antriebseinheiten 10 werden vorgesehen, wenn es sich um beispielsweise schwere Fahrzeuge 1 handelt, wobei hier zum Verschwenken des Führungsschuhs 6 die eine Antriebseinheit 10 eine Schubkraft und die andere Antriebseinheit 10 eine Zugkraft ausüben kann. Gegebenenfalls reicht auch eine Antriebseinheit aus. Wie in den Figuren 2 und 3 dargestellt, kann das Zurückführen des Führungsschuhs 6 in die Ruheposition durch Rückstellfedern 17 erfolgen, die auf die Schub- und Zugstangen 16 aufgeschoben sind und an dem Ansatz 15 angreifen. Damit der Führungsschuh 6 nach dem Verschwenken für eine gewisse Zeitdauer seine Position beibehält, damit die Spitze 13 sicher in die gewünschte Fahrbahn 4, 5 einfährt, wird bevorzugt eine Halteeinrichtung (nicht dargestellt) vorgesehen. Die Halteeinrichtung kann beispielsweise durch ein Zeitglied bestimmt werden, das in der Steuerung 11 ausgebildet ist.In FIGS. 2 and 3, vehicle 1 is not completely depicted for the sake of simplicity. Numeral 2 shows a side view of the drive units 10 which engage the guide shoe 6 via a push and pull rod 16. The guide shoe 6, which slides in a guide rail 2 embedded in the bottom 18 in FIG. 2, is connected to the push and pull rods 16 via an axis 14 and an extension 15. The drive units 10 are arranged on both sides of the guide shoe 6, which is why there is a symmetrical structure. Two drive units 10 are provided if, for example, heavy vehicles 1 are concerned, here for pivoting the guide shoe 6, one drive unit 10 can exert a pushing force and the other drive unit 10 can exert a pulling force. A drive unit may also be sufficient. As shown in FIGS. 2 and 3, the guide shoe 6 can be returned to the rest position by return springs 17, which are pushed onto the push and pull rods 16 and engage the shoulder 15. A holding device (not shown) is preferably provided so that the guide shoe 6 maintains its position for a certain period of time after the pivoting, so that the tip 13 safely enters the desired roadway 4, 5. The holding device can be determined, for example, by a timer which is formed in the control 11.
