Definitions
- the invention relates to a switch for a floor conveyor system according to the preamble of claim 1.
- a floor conveyor system is described in German patent application DE-A-34 04 805.
- the conventional electric transport vehicle shown in Fig. 1 has already been described in detail in German patent application DE-A-34 04 805. Reference is expressly made to this description for the purpose of disclosure.
- the electric transport vehicle 1 comprises a plate 10 on which the goods to be transported are placed or placed.
- a turntable 12 is rotatably mounted on the plate 10 about a vertical axis.
- a steering arm 14 extends forward, on which a front wheel 16 is mounted.
- the axle of the front wheel 16 is directly connected to an electric motor (not shown).
- a pantograph 18 is attached to the steering arm 14. This engages on a busbar within an underfloor guide rail 20.
- a guide pin 22 is attached, which also protrudes into the guide rail 20.
- a cantilever arm 24 is articulated at the front end of the steering arm 14, from which an axis 26 extends downward in the front region.
- a guide shoe 28 is articulated. This has the elongated shape of a boat, as shown in Fig. 3 in plan view.
- the guide shoe 28 consists either completely or at least partially of soft iron or another ferromagnetic material, so that it can be attracted by an electromagnet.
- the guide shoe 28 is tapered at its front end.
- the axis 26 is connected approximately centrally to the guide shoe 28 and the guide shoe projects backwards approximately to the guide pin 22.
- the steering arm 14 can be raised with the aid of a lifting device 30, so that the pantograph 18, the guide pin 22 and the guide shoe 28 from the underfloor - Guide rail can be pulled out.
- FIG. 3 shows the turnout area of the underfloor guide rail 20 in plan view.

- the right side wall of the guide rail 20 seen in the direction of movement is curved in the area of the switch.
- the area of curvature merges into a straight wall area at both ends.
- Behind the switch there is a wedge-shaped element 34 which defines the two additional side walls behind the fork.
- a plurality of electromagnets 42 are arranged one behind the other on both side walls of the switch region 36, ie the straight side wall 38 and the curved side wall 40.
- Each electromagnet consists of a magnetic core 44 and a winding 46.
- the magnetic core extends towards the side wall, so that the magnetic pole lies on the side wall.
- joint 52 may be provided with a horizontal joint axis, so that the guide shoe is movable on all sides.
- the switch works as follows. When an electric transport vehicle approaches the switch area, the electromagnets on one side or the electromagnets on the other side are selectively excited. It should be assumed that the upper electromagnets shown in FIG. 3, ie the electromagnets associated with the curved side wall of the switch, are excited. As soon as the guide shoe 28 comes from the magnetic area into the area of attraction of the electromagnets, it rests against the side wall. The electromagnets can be exposed in the area of the side wall. However, a cover plate 56 made of non-magnetic material can preferably also be provided. In the latter case, the guide shoe 28 lies against this plate 56 and slides along this plate.

Das in Fig. 1 gezeigte herkömmliche Elektrotransportfahrzeug wurde bereits in der deutschen Patentanmeldung DE-A-34 04 805 im einzelnen beschrieben. Auf diese Beschreibung wird zum Zwecke der Offenbarung ausdrücklich Bezug genommen. Das Elektrotransportfahrzeug 1 umfaßt eine Platte 10, auf die das zu transportierende Gut gelegt oder gestellt wird. Im vorderen Bereich ist ein Drehkranz 12 um eine vertikale Achse drehbar an der Platte 10 gelagert. Von diesem erstreckt sich ein Lenkarm 14 nach vorne, an dem ein Vorderrad 16 gelagert ist. Die Achse des Vorderrades 16 ist direkt mit einem Elektromotor verbunden (nicht gezeigt). Ferner ist an den Lenkarm 14 ein Stromabnehmer 18 befestigt. Dieser greift an einer Stromschiene innerhalb einer Unterflur-Führungsschiene 20 an. Am vorderen Ende des Lenkarms 14 ist ein Führungsbolzen 22 befestigt, welcher ebenfalls in die Führungsschiene 20 hineinragt. Ferner ist am vorderen Ende des Lenkarms 14 ein Auslegerarm 24 angelenkt, von dem sich im vorderen Bereich eine Achse 26 abwärts erstreckt. An derem unteren Ende ist ein Führungsschuh 28 angelenkt. Dieser hat die langgestreckte Gestalt eines Schiffchens, wie in Fig. 3 in Draufsicht gezeigt. Der Führungsschuh 28 besteht entweder vollständig oder zumindest teilweise aus Weicheisen oder einem anderen ferromagnetischen Werkstoff, so daß er von einem Elektromagneten angezogen werden kann. An seinem vorderen Ende ist der Führungsschuh 28 zugespitzt. Die Achse 26 ist etwa mittig mit dem Führungsschuh 28 verbunden und der Führungsschuh ragt rückwärts etwa bis zu dem Führungsbolzen 22. Der Lenkarm 14 ist mit Hilfe einer Hubeinrichtung 30 anhebbar, so daß der Stromabnehmer 18, der Führungsbolzen 22 und der Führungsschuh 28 aus der Unterflur-Führungsschiene herausziehbar sind.The conventional electric transport vehicle shown in Fig. 1 has already been described in detail in German patent application DE-A-34 04 805. Reference is expressly made to this description for the purpose of disclosure. The
Fig. 3 zeigt den Weichenbereich der Unterflur-Führungsschiene 20 in Draufsicht. Im Weichenbereich liegt eine Gabelung, in der von der Führungsschiene 20 eine Zweigschiene 32 nach rechts abzweigt. Bei der gezeigten Darstellung verläuft die Bewegungsrichtung von rechts nach links. Die in Bewegungsrichtung gesehen linke Seitenwand der Führungsschiene ist eine durchgehend gerade Seitenwand. Die in Bewegungsrichtung gesehen rechte Seitenwand der Führungsschiene 20 ist im Bereich der Weiche gekrümmt. Der Krümmungsbereich geht an beiden Enden jeweils in einen geraden Wandbereich über. Hinter der Weiche befindet sich ein keilförmiges Element 34, welches die beiden zusätzlichen Seitenwandungen hinter der Gabelungsstelle definiert. An beiden Seitenwandungen des Weichenbereichs 36, d.h. der geraden Seitenwandung 38 und der gekrümmten Seitenwandung 40 sind mehrere Elektromagnete 42 hintereinander angeordnet. Diese sind mit einer Stromversorgungs- und Steuereinrichtung verbunden. Jeder Elektromagnet besteht aus einem Magnetkern 44 und einer Wicklung 46. Der Magnetkern erstreckt sich zur Seitenwandung hin, so daß der Magnetpol an der Seitenwandung liegt. Über der Wicklung befindet sich eine Isolierungsschicht und auf dieser eine Abdeckplatte 50. Wie aus Fig. 4 ersichtlich ist, kann in der vertikalen Achse 26 des Führungsschuhs 28 noch ein weiteres Gelenk 52 mit einer horizontalen Gelenkachse vorgesehen sein, so daß der Führungsschuh allseitig beweglich ist.3 shows the turnout area of the
Die Weiche arbeitet folgendermaßen. Wenn sich ein Elektrotransportfahrzeug dem Weichenbereich nähert, so werden die Elektromagnete der einen Seite oder die Elektromagnete der anderen Seite selektiv erregt. Es soll angenommen werden, daß die in Fig. 3 gezeigten oberen Elektromagnete, d.h. die der gekrümmten Seitenwandung der Weiche zugeordneten Elektromagnete erregt werden. Sobald der Führungsschuh 28 aus magnetischem Bereich in den Anziehungsbereich der Elektromagnete kommt, legt er sich an die Seitenwandung an. In dem Bereich der Seitenwandung können die Elektromagnete frei liegen. Vorzugsweise kann jedoch auch eine Abdeckplatte 56 aus nichtmagnetischem Material vorgesehen sein. In letzterem Falle legt sich der Führungsschuh 28 an diese Platte 56 an und gleitet an dieser Platte entlang. Hierdurch wird ein Drehmoment auf dem Lenkarm 14 ausgeübt, so daß dieser zusammen mit den Führungsbolzen 22 verschwenkt wird, und zwar in einem im Verlauf der Vorwärtsbewegung des Elektrotransportfahrzeugs zunehmenden Maße. Der Führungsschuh fährt schließlich am Ende der Weiche mit seinem vorderen zugespitzten Ende in die Abzweigführungsschiene 32 ein. Er zieht hierdurch auch den Führungsbolzen 22 in diese Abzweigführungsschiene hinein, und im weiteren Verlauf übernimmt diese Abzweigführungsschiene 32 die Führungsfunktion im Sinne einer weitergehenden Verschwenkung des Lenkarms 14. Nachdem der Führungsschuh 28 den Weichenbereich verlassen hat, werden die Elektromagnete ausgeschaltet. Die hintereinanderliegenden Elektromagnete 42 können allesamt gleichzeitig erregt werden. Sie können aber auch nacheinander erregt werden. Falls das Elektrotransportfahrzeug geradeaus fahren soll, werden die in Fig. 3 gezeigten unteren Elektromagnete 42 erregt. Der Führungsschuh 28 legt sich somit an die gerade Innenwandung des Weichenbereichs an und das Elektrotransportfahrzeug behält seine Geradeausfahrt bei.The switch works as follows. When an electric transport vehicle approaches the switch area, the electromagnets on one side or the electromagnets on the other side are selectively excited. It should be assumed that the upper electromagnets shown in FIG. 3, ie the electromagnets associated with the curved side wall of the switch, are excited. As soon as the
