Abstract

PCT No. PCT/EP96/02058 Sec. 371 Date Dec. 12, 1997 Sec. 102(e) Date Dec. 12, 1997 PCT Filed May 14, 1996 PCT Pub. No. WO96/37394 PCT Pub. Date Nov. 28, 1996A conveyor carriage has running wheels guided in rail parts so as to prevent the conveyor carriage from lifting off transversely to the plane of the rails. Each conveyor carriage contains a driving unit with at least one driving wheel prestressed against the rail. In order to move the conveyor carriage manually, a lifting device allows the driving wheel to be lifted off and disengaged from the rail. In order to simplify the lifting device, the lifting device is equipped with a shaft mounted on the conveyor carriage adjoined to the driving unit by a flexible coupling member.

Description

Förderanlage mit In Schienen laufenden Fδrder agenConveyor system with conveyors running in rails
Die Erfindung betrifft eine Förderanlage gemäss Oberbegriff des Anspruches 1.The invention relates to a conveyor system according to the preamble of claim 1.
Eine Förderanlage der eingangs genannten Art ist aus der DE 33 09 377 A bekannt. Bei einer solchen Förderanlage weist eine Abhebe-Vorrichtung für das Antriebsrad einen Schwenkarm in auf, der an einem Ende an einer quer zur Schienenebene liegenden Achse verschwenkbar mit dem Fahrwerk verbunden ist und am anderen Ende einen Bahnfolger aufweist, der in eine mit der Antriebseinheit verbundene Führungsbahn eingreift. Die Führungsbahn definiert eine Grundstellung, in der das Antriebsrad an die Schiene vorgespannt ist, eine labile Abhebestellung, aus der das Antriebsrad bei fehlender Halte¬ kraft einer Person selbständig in die Grundstelung zurück¬ kehrt, sowie eine stabile Abhebestellung, in der das An¬ triebsrad auch ohne Einwirkung einer Person in Freistellung verharren soll. Nachteilig ist, dass diese Abhebe-Vorrichtung relativ kompliziert und insbesondere relativ viel Raum bean¬ sprucht. Ausserdem ist die stabile Abhebestellung nur scheinbar stabil, da keine Arretierung vorhanden ist und eine Vorspannfeder den Schwenkarm bei fehlender Haltekraft einer Person ebenfalls selbständig in die Grundstellung zurück¬ kehrt. Überdies ist die Handhabung der Abhebe-Vorrichtung sehr erschwert, da sie nur an der Unterseite des Förderwagens mittels eines erkzeges von aussen zugänglich ist. Aufgabe der Erfindung ist es, eine Förderanlage der eingangs genannten Art zu verbessern.A conveyor system of the type mentioned is known from DE 33 09 377 A. In such a conveyor system, a lifting device for the drive wheel has a swivel arm in which is pivotally connected to the chassis at one end on an axis lying transversely to the rail plane and has a path follower at the other end, which leads into a guide path connected to the drive unit intervenes. The guideway defines a basic position in which the drive wheel is pretensioned against the rail, an unstable lifting position from which the drive wheel automatically returns to the basic position when a person is not holding force, and a stable lifting position in which the drive wheel should remain in exemption even without the influence of a person. It is disadvantageous that this lifting device takes up a relatively complicated and in particular takes up a relatively large amount of space. In addition, the stable lifting position is only apparently stable, since there is no locking mechanism and a biasing spring also returns the swivel arm automatically to the basic position when a person is not holding force. In addition, the handling of the lifting device is very difficult because it is only accessible from the outside by means of a tool on the underside of the trolley. The object of the invention is to improve a conveyor system of the type mentioned.
Gelöst wird die Aufgabe erfindungsgemäss durch die kennzeich¬ nenden Merkmale des Anspruches 1. Die Abhebevorrichtung zeichnet sich aufgrund des auf einer Welle aufwickelbaren flexiblen Koppelgliedes durch einen ausserordentlich einfa¬ chen, platzsparenden und sicheren Aufbau aus. Der auf der Aussenseite des Fahrwerks angebrachte Handgriff ermöglicht eine einfache, jederzeit mögliche Handhabung ohne zusätzliche Werkzeuge.According to the invention, the object is achieved by the characterizing features of claim 1. The lifting device is distinguished by an extraordinarily simple, space-saving and safe structure due to the flexible coupling member that can be wound on a shaft. The handle attached to the outside of the undercarriage enables easy handling at any time without additional tools.
Vorteilhafte Ausgestaltungen der Förderanlage sind in den Ansprüchen 2 bis 4 beschrieben.Advantageous embodiments of the conveyor system are described in claims 2 to 4.
Besonders vorteilhaft ist es, wenn die Abhebe-Vorrichtung nach Anspruch 2 so ausgestaltet ist, dass sie in der abgeho¬ benen stabilen Stellung des Antriebsrades arretierbar ist, um die Abhebe-Vorrichtung nicht so lange betätigt halten zu müssen, bis beispielsweise ein Verschiebevorgang des Förder¬ wagens beendet ist. Allerdings sollte die Arretierung nicht in jedem Fall eintreten, sondern erst in einer zweiten Phase der Verstellung, das heisst der Arretierstellung der Abhebe- Vorrichtung, während in einer ersten labilen Phase, das heisst der Abhebestellung, die Abhebe-Vorrichtung stets von Hand gehalten werden muss, um sicher zu stellen, dass beim Auslassen der Abhebe-Vorrichtung das automatische Eingreifen der Antriebsvorrichtung an der Schiene gewährleistet ist. Der Anspruch 3 bezeichnet eine vorteilhafte Lösung der Arretie¬ rung der Abhebe-Vorrichtung.It is particularly advantageous if the lifting device is designed in such a way that it can be locked in the lifted stable position of the drive wheel, in order not to have to keep the lifting device operated until, for example, a displacement process of the conveyor ¬ car is finished. However, the locking should not always occur, but only in a second phase of the adjustment, i.e. the locking position of the lifting device, while in a first unstable phase, i.e. the lifting position, the lifting device must always be held by hand to ensure that the automatic engagement of the drive device on the rail is ensured when the lifting device is let out. The claim 3 designates an advantageous solution of the locking of the lifting device.
Besonders vorteilhaft ist auch eine Weiterbildung der Förder¬ anlage gemäss Anspruch 4, die ein ungewolltes Abheben des Antriebsrades von der Schiene sicherstellt. Ein Ausführungsbeispiel des Förderwagens wird nachfolgend anhand von Zeichnungen schematisch beschrieben, dabei zeigen:A further development of the conveyor system according to claim 4 is particularly advantageous, which ensures that the drive wheel is lifted off the rail unintentionally. An exemplary embodiment of the trolley is described schematically below with reference to drawings, in which:

Schnitt IV-IV der Figur 2.Section IV-IV of Figure 2.
Die in den Figuren im Ausschnitt dargestellten Teile der Förderanlage zeigen das Fahrwerk 2 eines Förderwagens 4 in einer Schiene 6. Der Förderwagen enthält Laufrollen 8 sowie ein von einer Antriebseinheit 10 angetriebenes Antriebsrad 12, das sich im vorliegenden Fall aus einem Reibrad 12a und einem Zahnrad 12b zusammensetzt. Der Förderwagen 4 läuft in einer Schiene 6, die ein Abheben des Förderwagens quer zur Schienen-Ebene verhindert. Die Schiene enthält beispielsweise eine Schienenbasis 14 und seitliche Schienenteile 16, welche die Laufrollen 8 C-förmig umgreifen, so dass der Förderwagen 4 nicht senkrecht aus den Schienen abgenommen werden kann.The parts of the conveyor system shown in detail in the figures show the undercarriage 2 of a trolley 4 in a rail 6. The trolley contains rollers 8 and a drive wheel 12 driven by a drive unit 10, which in the present case consists of a friction wheel 12a and a gear wheel 12b put together. The trolley 4 runs in a rail 6, which prevents the trolley from lifting transversely to the rail plane. The rail contains, for example, a rail base 14 and lateral rail parts 16, which encompass the rollers 8 in a C-shape, so that the trolley 4 cannot be removed vertically from the rails.
Die Antriebseinheit 10 ist um eine parallel zur Achse 18 des Antriebsrades 12 parallele Achse 20 schwenkbar im Rahmen 22 des Fahrwerkes 2 gelagert. Eine Vorspannfeder 24 spannt das Antriebsrad 12 gegen die Schienenbasis 14 vor, so dass entwe¬ der das Reibrad 12a mit einer Reibfläche 26 der Schienenbasis 14 in Eingriff steht oder wie im gezeigten Beispiel das Zahnrad 12b mit einer Zahnstange 28 an der Schienenbasis 14. Der Förderwagen 4 ist mit einer von aussen von Hand bedienba¬ ren Vorrichtung 30 zum Abheben des Antriebsrades 12 bzw. 12a,12b von der Schiene 6 ausgestattet. Diese Abhebe- Vorrichtung 30 enthält eine parallel zur Antriebsachse an¬ geordnete Welle 32, die im Fahrwerk 2 drehbar und in axialer Richtung verschiebbar gelagert ist. Die Welle ist mit einem Handgriff 34 versehen, der einerseits das Verschwenken der Welle 32 und andererseits das axiale Verschieben der Welle 32 ermöglicht, wie nachfolgend noch näher beschrieben wird. Die Welle 32 ist mit einem Anschlagnocken 36 versehen, der in der Grundstellung SO gemäss Figur 1 an einem Ansatz 38 der An¬ triebseinheit 10 ansteht, um deren Verschwenken zu verhin¬ dern. Weiter ist die Welle 32 mittels eines Koppelgliedes 40 mit der Antriebseinheit 10 verbunden, wobei das Koppelglied 40 aus einem flexibelen Element beispielsweise einem Seil, Gurt oder Band besteht, dessen eines Ende 42 an der Antriebs¬ einheit 10 und dessen anderes Ende 43 an der Welle 32 befe¬ stigt ist. Beim Verschwenken der Welle 32 wird das Koppel¬ glied 40 auf der Welle aufgewickelt, wobei gleichzeitig der Anschlagnocken 36 am Ansatz 38 ausser Eingriff gebracht wird und das Koppelglied 40 auf der Welle 32 aufgewickelt wird. Dadurch wird die Antriebseinheit 10 entgegen der Kraft der Vorspannfeder 24 verschwenkt, bis das Antriebsrad 12 an der Schiene 16 ausser Eingriff steht.The drive unit 10 is pivotally mounted in the frame 22 of the chassis 2 about an axis 20 parallel to the axis 18 of the drive wheel 12. A biasing spring 24 biases the drive wheel 12 against the rail base 14, so that either the friction wheel 12a engages with a friction surface 26 of the rail base 14 or, as in the example shown, the gearwheel 12b with a rack 28 on the rail base 14. The trolley 4 is equipped with a device 30 operable by hand from the outside for lifting the drive wheel 12 or 12a, 12b from the rail 6. This lifting device 30 contains a shaft 32 arranged parallel to the drive axis, which is rotatably mounted in the undercarriage 2 and is displaceable in the axial direction. The shaft is provided with a handle 34 which on the one hand enables the shaft 32 to be pivoted and on the other hand enables the shaft 32 to be axially displaced, as will be described in more detail below. The shaft 32 is provided with a stop cam 36 which, in the basic position SO according to FIG. 1, bears against a shoulder 38 of the drive unit 10 in order to prevent it from pivoting. Furthermore, the shaft 32 is connected to the drive unit 10 by means of a coupling member 40, the coupling member 40 consisting of a flexible element, for example a rope, belt or belt, one end 42 of which on the drive unit 10 and the other end 43 of which on the shaft 32 is attached. When the shaft 32 is pivoted, the coupling member 40 is wound on the shaft, the stop cam 36 on the shoulder 38 being disengaged at the same time and the coupling member 40 being wound on the shaft 32. As a result, the drive unit 10 is pivoted against the force of the biasing spring 24 until the drive wheel 12 is disengaged from the rail 16.
Die Abhebe-Vorrichtung 30 ist nun mit einer Arretiervorrich¬ tung 44 versehen, die die Abhebe-Vorrichtung in der in Figur 1 gezeigten Grundstellung SO arretiert, um ein ungewolltes Verschwenken der Welle 32 zu verhindern. Hierzu ist die Welle 32 mit einem Absatz 46 versehen, so dass die Welle 32 mittels einer VorSpannfeder 48 über den Absatz 46 an einer Wand 50, die dem Handgriff 34 abgewandt ist, zur Anlage gebracht ist. In der Wand 50 ist eine Bohrung 52 enthalten, die diametral gegenüberliegend zwei radiale Ausnehmungen 54 enthält, in die jeweils ein radialer Ansatz 56 der Welle 32 eingreift und so die Welle gegen Verschwenken sichert. Die Welle 32 kann nun mittels des Handgriffes 34 in axialer Richtung 58 so weit verschoben werden, bis die Welle mittels eines Sicherungsrin¬ ges 60 an der Aussenseite der Wand 50 ansteht, wodurch die radialen Ansätze 56 an den radialen Ausnehmungen 54 ausser Eingriff kommen und die Welle verschwenkt werden kann, wie aus Figur 1 hervorgeht. Die Stellung SO ist die Grundstel¬ lung, in der das Antriebsrad 12 an der Schienenbasis 14 in Eingriff steht. Durch Verschwenken um ca. 30° in di« erste Stellung Sl wird der Anschlagnocken 36 freigegeben. Durch weiteres Verschwenken um 90° in die Stellung S2 kommt das Zahnrad 12b von der Zahnstange 28 frei, so dass der Förderwa¬ gen längs der Schiene 6 verschoben werden kann. In dieser Stellung muss der Handgriff 34 von Hand gehalten werden, andernfalls würde die VorSpannfeder 24 die Antriebseinheit 10 in die Grundstellung zurückbewegen. Erst durch Weiterschwen¬ ken des Handgriffes 34 um 180° aus der Grundstellung SO in die Stellung S3 kann die Abhebe-Vorrichtung 30 arretiert wer¬ den, indem die radialen Ansätze 56 in die radialen Ausnehmun¬ gen 54 einrasten. Eine solche Arretierung ist allerdings nur in einem waagrechten Verlauf der Schiene empfehlenswert. Bei geneigtem oder gar senkrechtem Verlauf der Schiene sollte die Arretierung nicht verwendet werden, um sicherzustellen, dass bei einem unbeabsichtigten Loslassen des Handgriffes 34 das Zahnrad 12b sofort mit der Zahnstange 28 in Eingriff kommt um ein ungewolltes Abfahren des Förderwagens zu verhindern. The lifting device 30 is now provided with a locking device 44 which locks the lifting device in the basic position SO shown in FIG. 1 in order to prevent the shaft 32 from swiveling unintentionally. For this purpose, the shaft 32 is provided with a shoulder 46, so that the shaft 32 is brought into abutment by means of a pretensioning spring 48 via the shoulder 46 against a wall 50 which faces away from the handle 34. A bore 52 is contained in the wall 50, which contains two radial recesses 54 diametrically opposite one another, into which in each case a radial shoulder 56 of the shaft 32 engages and thus secures the shaft against pivoting. The shaft 32 can now be displaced in the axial direction 58 by means of the handle 34 until the shaft abuts on the outside of the wall 50 by means of a locking ring 60, as a result of which the radial lugs 56 disengage from the radial recesses 54 and the Wave can be pivoted, as shown in Figure 1. The position SO is the basic position in which the drive wheel 12 is engaged on the rail base 14. The stop cam 36 is released by pivoting about 30 ° into the first position S1. By further pivoting through 90 ° into position S2, the gear wheel 12b is freed from the rack 28, so that the conveyor car can be moved along the rail 6. In this position, the handle 34 must be held by hand, otherwise the biasing spring 24 would move the drive unit 10 back into the basic position. The lifting device 30 can only be locked by swiveling the handle 34 through 180 ° from the basic position SO to the position S3, in that the radial projections 56 snap into the radial recesses 54. Such locking is only recommended in a horizontal course of the rail. If the rail is inclined or even vertical, the locking mechanism should not be used to ensure that if the handle 34 is released unintentionally, the gearwheel 12b immediately engages with the toothed rack 28 in order to prevent the trolley from unintentionally moving away.
