Abstract

An overhead conveyor system for conveying objects comprises at least one supporting rail (16) with at least one supporting frame (48), which has at least one section that is slanted with regard to a horizontal plane, which accommodates at least one driving means (22) and at least one object (60), is connected to the driving means (22), and which is displaceably guided by the supporting rail (16). The supporting frame (48) can pivot about a horizontal pivot pin (36) that is essentially perpendicular to the direction of motion of the supporting frame. The invention also relates to a method for operating an overhead conveyor system of the aforementioned type, according to which the supporting frame (48) is prevented from swinging about the pivot pin (36) by a braking device (76, 92).

Description

Die Erfindung betrifft eine Hängebahnsystem zum Transport von Gegenständen nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a monorail system for the transport of objects according to the preamble of patent claim 1.

Außerdem betrifft die Erfindung ein Verfahren zum Betreiben eines Hängebahnsystems.Moreover, the invention relates to a method for operating a monorail system.

Hängebahnsysteme ähnlich denen der eingangs genannten Art sind an sich bekannt und werden beispielsweise verwendet, um auf Paletten gestapelte Gegenstände, wie z.B. gefüllte oder leere Getränkekästen, zu transportieren. So kann es sich bei dem Ort der Beladung des Hängebahnsystems zum Beispiel um eine Abfüllanlage für Getränke und bei dem Ort der Entladung des Hängebahnsystems um eine Lagerhalle handeln.Monorail systems similar to those of the type mentioned in the opening paragraph are known per se and are used, for example, for stacking articles stacked on pallets, such as e.g. filled or empty beverage crates to transport. For example, the place of loading of the monorail system may be a bottling plant for drinks and the place of unloading of the monorail system may be a warehouse.

Es kommt häufig vor, dass zwischen dem Ort der Beladung des Traggestells und dem Entladeort ein Höhenunterschied besteht. Dieser kann dadurch ausgeglichen werden, dass die Tragschiene des Hängebahnsystems wenigstens einen gegenüber der horizontalen Ebene geneigten Abschnitt umfasst. Bei üblicherweise eingesetzten Hängebahnsystemen folgt das Traggestell jedoch der Neigung der Tragschiene und verkippt entsprechend gegenüber der Vertikalen. Die auf dem Traggestell angeordneten Gegenstände werden dann ebenfalls gegenüber einer Vertikalen verkippt, was dazu führen kann, dass die Gegenstände aus dem Traggestell herausfallen, wenn sie nicht zusätzlich in irgendeiner Form, beispielsweise durch Spanngurte, befestigt werden.It often happens that there is a difference in height between the location of the loading of the support frame and the unloading. This can be compensated by the fact that the mounting rail of the monorail system comprises at least one section inclined with respect to the horizontal plane. In commonly used monorail systems, however, the support frame follows the inclination of the support rail and tilted accordingly relative to the vertical. The arranged on the support frame objects are then also tilted relative to a vertical, which can cause the objects fall out of the support frame, if they are not additionally attached in any form, for example by straps.

Das Anbringen bzw. Lösen dieser notwendigen Befestigung des zu transportierenden Transportguts erhöht jedoch den Zeitaufwand sowohl beim Be- als auch beim Entladen des Traggestells. Dadurch kommt es zu Verzögerungen beim Be-oder Entladen, die den Gesamtdurchsatz des Hängebahnsystems verringern. Insgesamt können diese Verzögerungen die Kosten erhöhen.However, the attachment or detachment of this necessary attachment of the transported goods to be transported increases the time required both loading and unloading of the support frame. This leads to delays in loading or unloading, which reduce the overall throughput of the monorail system. Overall, these delays can increase costs.

Ein Hängebahnsystem der eingangs genannten Art ist aus der DE 40 02 181 A1 bekannt geworden. An einer Einschienenanordnung lässt sich ein motorgetriebenes Fahrgestell bewegen, welches an seiner Unterseite eine Hubvorrichtung trägt, an der ihrerseits eine höhenveränderliche Handhabungsvorrichtung um eine horizontale Achse drehbar gelagert ist. Dadurch kann es bei Beschleunigungs- oder Bremsvorgängen zu Schwingungen der Handhabungsvorrichtung kommen, die zwar durch eine Dämpfungseinrichtung gemildert werden, wobei jedoch ein zumindest zeitweises Schrägstellen der Handhabungseinrichtung nicht zuverlässig verhindert werden kann.A monorail system of the type mentioned is from the DE 40 02 181 A1 known. On a monorail arrangement, a motor-driven chassis can be moved, which carries on its underside a lifting device on which in turn a height-adjustable handling device is rotatably mounted about a horizontal axis. As a result, oscillations of the handling device may occur during acceleration or braking processes, which are indeed mitigated by a damping device, but an at least temporary tilting of the handling device can not be reliably prevented.

Ähnliche verhält es sich bei einer aus der DE 24 38 570 A1 bekannten Aufhängung für ein Fördermittel. Dort ist eine Dämpfungseinrichtung dafür vorgesehen, quer zur Fahrtrichtung erfolgende Auslenkungen einer Kabine bei Kurvenfahrt zu stabilisieren.Similar is one of the DE 24 38 570 A1 known suspension for a subsidy. There, a damping device is provided to stabilize transversely to the direction of travel deflections of a cabin when cornering.

Aufgabe der vorliegenden Erfindung ist es, ein Hängebahnsystem der eingangs genannten Art zu schaffen, welches die oben genannten Befestigungsmaßnahmen vermeidet und dennoch auch bei Vorliegen äußerer Störkräfte, z. B. Beschleunigungskräfte, das Herausfallen der transportierten Gegenstände sicher vermeidet.Object of the present invention is to provide a monorail system of the type mentioned, which avoids the above-mentioned attachment measures and still in the presence of external disturbance forces, z. B. acceleration forces, the falling out of the transported objects safely avoids.

Diese Aufgabe wird durch ein Hängebahnsystem mit den Merkmalen des Patentanspruchs 1 gelöst.This object is achieved by a monorail system with the Characteristics of claim 1 solved.

Wie bei der oben genannten DE 40 02 181 A1 ist gewährleistet, dass sich das Traggestell vertikal ausrichten kann, wenn es in einen geneigten Abschnitt der Tragschiene einfährt oder sich in einem solchen Abschnitt befindet. Das auf das Traggestell aufgebrachte Transportgut führt durch seine Gewichtskraft zu einem Verschwenken des Traggestells um die Schwenkachse, wodurch die Gewichtskraft des Transportguts stets im wesentlichen vertikal nach unten wirkt und ein Verkippen des Transportguts, welches aus einem oder mehreren Gegenständen bestehen kann, verhindert ist.As with the above DE 40 02 181 A1 it is ensured that the support frame can be vertically aligned when it enters or is located in an inclined portion of the support rail in such a section. The applied to the support frame cargo leads by its weight to a pivoting of the support frame about the pivot axis, whereby the weight of the cargo always acts substantially vertically down and tilting of the cargo, which may consist of one or more objects is prevented.

Dadurch, dass eine Bremseinrichtung vorgesehen ist, lässt sich ein Schwingen des Traggestells um die Schwenkachse unterbinden.Characterized in that a braking device is provided, a swinging of the support frame about the pivot axis can be prevented.

Unter Schwingen ist hier zu verstehen, dass das Traggestell um die Schwenkachse pendelt. Fährt nämlich das Traggestell beispielsweise mit konstanter Geschwindigkeit in einen nach oben geneigten Abschnitt der Tragschiene ein, so verschwenkt es bei höheren Transportgeschwindigkeiten zunächst um die Schwenkachse in Transportrichtung. Diese Schwenkbewegung, welche noch nicht als Schwingen zu bezeichnen ist, kann gewünscht sein, da so auf das Transportgut ausgeübte Kräfte durch das Traggestell aufgefangen werden können. Im Anschluss daran würde das Traggestell jedoch wieder zur Vertikalen, darüberhinaus bis zu einem Umkehrpunkt und wieder zurück schwingen und somit eine Pendelbewegung vollziehen. Diese Pendelbewegung kann jedoch dazu führen, dass das Transportgut aus dem Traggestell herausfällt, wenn es nicht darin befestigt ist.Under swinging is to be understood here that the support frame oscillates about the pivot axis. For if the support frame, for example, moves at a constant speed into an upwardly inclined section of the support rail, it initially pivots at higher transport speeds about the pivot axis in the transport direction. This pivoting movement, which is not yet to be described as swinging, may be desired, as can be absorbed by the support frame forces exerted on the cargo in this way. Following this, however, the support frame would swing back to the vertical, moreover, up to a reversal point and back again and thus perform a pendulum motion. However, this pendulum movement can cause the cargo to fall out of the support frame if it is not secured therein.

Fährt das Traggestell in einen nach unten geneigten Abschnitt der Tragschiene ein, so erfolgt das erste Verschwenken ebenfalls in der Transportrichtung, woran sich - ohne Bremseinrichtung - wiederum ein Schwingen des Transportgestells um die Schwenkachse mit denselben möglichen Folgen für das Transportgut anschließt.Moves the support frame in a downwards inclined Section of the support rail, the first pivoting also takes place in the transport direction, which - without braking device - in turn followed by a swinging of the transport frame about the pivot axis with the same possible consequences for the transported.

Durch die Bremseinrichtung wird dieses Schwingen des Traggestells unterbunden, wodurch verhindert wird, dass Transportgut aus dem Traggestell herausfällt.By the braking device of this swinging of the support frame is prevented, thereby preventing transporting material falls out of the support frame.

Erfindungsgemäß ist das Traggestell durch die Bremseinrichtung in einer vertikalstellung arretierbar. Als Vertikalstellung wird hier eine Stellung bezeichnet, bei der das Traggestell vertikal ausgerichtet ist. Durch die Arretierung gewinnt das Traggestell eine erhöhte Robustheit gegen äußere Störeinflüsse wie Beschleunigungskräfte, Stöße oder Vibrationen, die zu einer Abweichung von der Vertikalen führen könnten, welche wiederum mit einer Gefahr des Herausfallens der transportierten Gegenstände verbunden wäre.According to the invention, the support frame can be locked by the braking device in a vertical position. As a vertical position, a position is referred to here, in which the support frame is vertically aligned. By locking the support frame gains an increased robustness against external disturbances such as acceleration forces, shocks or vibrations that could lead to a deviation from the vertical, which in turn would be associated with a risk of falling out of the transported objects.

Das Traggestell bleibt dann sowohl bei einem horizontalen als auch bei einem geneigten Verlauf der Tragschiene vertikal ausgerichtet, wogegen in einem Übergangsbereich der Tragschiene von einem horizontalen zu einem geneigten Abschnitt die Arretierung gelöst werden kann, damit sich das Traggestell durch seine eigene und gegebenenfalls durch die Gewichtskraft des Transportguts zur Vertikalen ausrichten kann.The support frame then remains vertically aligned both in a horizontal and in an inclined course of the support rail, whereas in a transition region of the support rail from a horizontal to an inclined portion, the lock can be solved so that the support frame by its own and optionally by the weight of the cargo to the vertical can align.

Eine vorteilhafte Ausgestaltung der Bremseinrichtung besteht darin, dass sie einen Hydraulikzylinder umfasst, der zwischen dem Traggestell und einem relativ zu dem Traggestell feststehenden Teil angeordnet ist und dessen fluidgefüllte Kammern über eine Fluidleitung miteinander kommunizieren. Das Unterbinden eines Schwingens des Traggestells um die Schwenkachse kann zum einen dadurch erfolgen, dass die Fluidleitung einen geeigneten Querschnitt aufweist, um die Schwingung abzudämpfen. Zum anderen besteht die Möglichkeit, den Fluidstrom der beiden fluidgefüllten Kammern des Hydraulikzylinders zu unterbrechen, wodurch die oben angesprochene Arretierung erzielt werden kann.An advantageous embodiment of the braking device is that it comprises a hydraulic cylinder, which is arranged between the support frame and a fixed relative to the support frame part and its fluid-filled chambers via a fluid line with each other communicate. The suppression of a swinging of the support frame about the pivot axis can on the one hand take place in that the fluid line has a suitable cross-section in order to damp the vibration. On the other hand, it is possible to interrupt the fluid flow of the two fluid-filled chambers of the hydraulic cylinder, whereby the above-mentioned locking can be achieved.

Dies wird vorteilhaft dadurch erreicht, dass in der Fluidleitung des Hydraulikzylinders ein Drosselventil vorgesehen ist. Ein solches Drosselventil eröffnet sowohl die Möglichkeit, den Durchlassquerschnitt für das Fluid in der Fluidleitung zu verringern als auch den Durchlass ganz zu verschließen.This is advantageously achieved in that a throttle valve is provided in the fluid line of the hydraulic cylinder. Such a throttle valve opens both the possibility of reducing the passage cross section for the fluid in the fluid line and to close the passage completely.

Eine günstige Weiterentwicklung besteht darin, dass die Bremseinrichtung eine Steuereinrichtung umfasst, über die das Drosselventil einstellbar ist. Dadurch lässt sich der oben angesprochene Arretier/Löse-Vorgang kontrolliert steuern.A favorable further development is that the braking device comprises a control device, via which the throttle valve is adjustable. As a result, the above-mentioned locking / releasing process can be controlled controlled.

Dabei ist es günstig, wenn der Steuereinrichtung Signale von einer von dem Antriebsmittel mitgeführten Sensoreinheit zuführbar sind, welche eine entlang der Tragschiene angeordnete Codierung ausliest. Eine solche Codierung kann beispielsweise Positionsangaben umfassen, aufgrund derer die Steuereinrichtung das Drosselventil ansteuert.It is advantageous if the control device signals from a guided by the drive means sensor unit can be fed, which reads a arranged along the support rail coding. Such coding may include, for example, position information, on the basis of which the control device controls the throttle valve.

Es ist hilfreich, wenn das relativ zu dem Traggestell feststehende Teil ein mit dem Antriebsmittel starr verbundener Tragholm ist. An diesem kann das Traggestell sicher befestigt werden.It is helpful if the fixed relative to the support frame part is rigidly connected to the drive means carrier beam. At this, the support frame can be securely attached.

Eine günstige Ausgestaltung der Schwenkachse besteht darin, dass der Tragholm ein die Schwenkachse bildendes Gelenk trägt, welches mit dem Traggestell verbunden ist.A favorable embodiment of the pivot axis exists in that the carrier beam carries a pivot axis forming the joint, which is connected to the support frame.

Wenn die Tragschiene des Hängebahnsystems nicht nur nach oben oder nach unten geneigte Abschnitte aufweist, sondern teilweise auch in einer Kurve verläuft, ist es günstig, wenn das Traggestell um eine weitere Schwenkachse verschwenkbar ist, welche im wesentlichen parallel zu seiner Bewegungsrichtung verläuft. Somit kann das Traggestell in einer Kurve bezogen auf seine Bewegungsrichtung seitlich verschwenken, wodurch Fliehkräfte teilweise abgefangen werden können.If the support rail of the monorail system not only has upwardly or downwardly inclined portions, but also partially extends in a curve, it is advantageous if the support frame is pivotable about a further pivot axis which extends substantially parallel to its direction of movement. Thus, the support frame can pivot laterally relative to its direction of movement in a curve, as a result of which centrifugal forces can be partially absorbed.

Vorteilhaft ist es dabei, wenn Dämpfungsglieder vorgesehen sind, welche die Schwenkbewegung des Traggestells um die weitere Schwenkachse dämpfen.It is advantageous if attenuators are provided which damp the pivotal movement of the support frame about the further pivot axis.

Aufgabe der Erfindung ist es außerdem, ein Verfahren zum Betreiben eines Hängebahnsystems zum Transport von Gegenständen zur Verfügung zu stellen, wobei das Hängebahnsystem die Merkmale des Oberbegriffs des Patentanspruchs 1 aufweist.The object of the invention is also to provide a method for operating a monorail system for the transport of objects available, wherein the monorail system having the features of the preamble of claim 1.

Der Aufgabe liegt die oben angesprochene Problematik zugrunde, dass es zu einer ein Herausfallen des Transportguts aus dem Traggestell verursachenden Schieflage kommen kann, wenn das Traggestell entsprechenden Störkräften ausgesetzt ist.The object is based on the above-mentioned problem that can lead to a falling out of the cargo from the support frame causing skew when the support frame is exposed to corresponding disturbing forces.

Dieses Problem wird durch ein Verfahren nach dem Patentanspruch 10 gelöst.This problem is solved by a method according to claim 10.

Ein weiterer vorteilhafter Verfahrensschritt findet sich im zugehörigen Unteranspruch. Die Vorteile des Verfahrens entsprechen denjenigen, die an entsprechender Stelle zu den Vorrichtungsmerkmalen erläutert wurden.Another advantageous method step can be found in the associated dependent claim. The advantages of the procedure correspond to those which have been explained in the appropriate place to the device features.

An embodiment of the invention will be explained in more detail with reference to the drawing. In this show:

a section of a monorail system for transporting objects in a side view with horizontally extending mounting rail;
FIG. 2
a rear view of the in FIG. 1 suspended system shown in the transport direction shown;

FIG. 4

Die Figuren 1 und 2 zeigen ein Hängebahnsystem 10 zum Transport von Gegenständen, wie es beispielsweise zum Transport von mit Transportgut beladenen Paletten eingesetzt wird.The FIGS. 1 and 2 show a monorail system 10 for the transport of objects, as used for example for the transport of transported goods loaded pallets.

Das Hängebahnsystem 10 umfasst eine Halteschiene 12, welche beispielsweise an der Decke einer Halle oder an Stützpfeilern (nicht dargestellt) in an sich bekannter Weise befestigt ist und an deren Unterseite in Längsrichtung voneinander beabstandet Verbindungsstücke 14 befestigt sind, von denen in Figur 1 zwei zu erkennen sind.The monorail system 10 comprises a retaining rail 12, which, for example, on the ceiling of a hall or on pillars (not shown) in per se known Is attached manner and at the bottom thereof in the longitudinal direction spaced from each other fasteners 14 are fixed, of which in FIG. 1 two are visible.

Eine Tragschiene 16 ist über C-förmige Befestigungsglieder 18 derart an den Verbindungsstücken 14 der Halteschiene 12 befestigt, daß die Tragschiene 16 vertikal beabstandet von und parallel zu der Halteschiene 12 verläuft. Das Ende eines Schenkels der C-förmigen Befestigungsglieder 18 ist dabei jeweils mit einer vertikalen Seitenfläche der Tragschiene 16 verbunden, wogegen der andere Schenkel an dem Verbindungsstück 14 an der Halteschiene 12 befestigt ist.A support rail 16 is attached via C-shaped attachment members 18 to the connecting pieces 14 of the support rail 12 such that the support rail 16 vertically spaced from and parallel to the support rail 12 extends. The end of a leg of the C-shaped fastening members 18 is in each case connected to a vertical side surface of the support rail 16, whereas the other leg is attached to the connecting piece 14 on the support rail 12.

Auf der Tragschiene 16 fahren zwei in einer Transportrichtung T voneinander beabstandete rollengeführte Antriebswagen 20, welche die Tragschiene 16 von deren freien Längsseite her umgreifen, wie dies an sich bekannt ist. Wie insbesondere in Figur 2 zu erkennen ist, wird jeder Antriebswagen 20 mittels eines darauf angebrachten Elektromotors 22 angetrieben. Auch andere Antriebsarten, wie eine mit den Antriebswagen 20 verbundene entlang der Tragschiene 16 verlaufende Antriebskette, sind möglich.On the support rail 16 drive two in a transport direction T spaced from each other roller-guided drive carriage 20, which surround the support rail 16 of the free longitudinal side thereof, as is well known. As in particular in FIG. 2 can be seen, each drive carriage 20 is driven by means of an electric motor 22 mounted thereon. Other drive types, such as connected to the drive carriage 20 along the support rail 16 extending drive chain are possible.

Die Transportrichtung T wird hier lediglich als Bezugsrichtung verwendet. Es versteht sich, daß das Hängebahnsystem 10 auch in einer Transportrichtung betrieben werden kann, die der hier angenommenen Transportrichtung T entgegengesetzt ist. D.h., die Bewegungsrichtung des Hängebahnsystems 10 verläuft entlang der Tragschiene 16 in beiden Richtungen.The transport direction T is used here only as a reference direction. It is understood that the overhead conveyor system 10 can also be operated in a transport direction, which is opposite to the transport direction T assumed here. That is, the direction of movement of the monorail system 10 is along the support rail 16 in both directions.

Die Antriebswagen 20 sind über einen Tragholm 24 starr miteinander verbunden, dessen Endbereiche 26 und 28 an der Unterseite jeweils eines Antriebswagens 20 befestigt sind.The drive carriage 20 are rigidly connected to each other via a support rail 24, whose end portions 26 and 28 at the bottom of each drive carriage 20 are attached.

Der Tragholm 24 weist mittig einen nach unten weisenden Befestigungsflansch 30 auf, an den ein erstes Gelenkteil 32 eines Gelenks 34 befestigt ist. Das erste Gelenkteil 32 ist über eine senkrecht auf der Transportrichtung T stehende horizontale Schwenkachse 36 mit einem zweiten Gelenkteil 38 des Gelenks 34 verbunden.The support beam 24 has centrally a downwardly facing mounting flange 30, to which a first hinge part 32 of a joint 34 is attached. The first joint part 32 is connected via a perpendicular to the transport direction T horizontal pivot axis 36 with a second joint part 38 of the joint 34.

Das zweite Gelenkteil 38 des Gelenks 34 wiederum ist mittig an dem Mittelholm 40 einer Doppel-T-förmigen Trägerstruktur 42 befestigt, deren einer Querholm 44 in Figur 2 zu erkennnen ist.The second joint part 38 of the joint 34 in turn is centrally attached to the central spar 40 of a double-T-shaped support structure 42, whose one transverse bar 44 in FIG. 2 is to be recognized.

Über Scharniere 46 ist ein Traggestell 48 derart an dem Mittelholm 40 der Trägerstruktur 42 befestigt, daß es um die Scharnierachsen verschwenken kann, welche parallel zur Transportrichtung T stehen.By hinges 46, a support frame 48 is secured to the central spar 40 of the support structure 42 so that it can pivot about the hinge axes, which are parallel to the transport direction T.

Das Traggestell 48 umfaßt einen rechteckigen, in Figur 1 horizontal liegenden Gestellrahmen 50, an dem die Scharniere 46 befestigt sind. Von den Eckbereichen des Gestellrahmens 50 geht jeweils in Figur 1 senkrecht nach unten ein Gestellholm 52 ab, von denen jeweils die beiden am gleichen Längsende des Gestellrahmens 50 angebrachten Gestellholme 52 durch senkrecht zur Bewegungsrichtung angeordnete horizontale Querstreben 54 zu einem Gestellgerüst 56 verbunden sind. Mit ihren bodenseitigen Enden bilden die Gestellholme 52 eine Aufnahmestruktur 58, auf die Transportgut aufgebracht werden kann. Beim hier beschriebenen Ausführungsbeispiel sind die Aufnahmestruktur 58 und insgesamt das Traggestell 48 derart dimensioniert, daß das Traggestell 48 mit Transportgut 60 beladene Paletten 62 aufnehmen kann, wie es in den Figuren durch gestrichelte Linien angedeutet ist. Bei dem Transportgut 60 kann es sich sowohl um einen einzelnen Gegenstand als auch um mehrere auf der Palette 62 gestapelte Gegenstände handeln.The support frame 48 comprises a rectangular, in FIG. 1 horizontal frame frame 50 to which the hinges 46 are attached. From the corner areas of the rack 50 goes in each case FIG. 1 vertically down from a frame spar 52 from, in each case the two attached to the same longitudinal end of the frame frame 50 frame beams 52 are connected by perpendicular to the direction of horizontal horizontal struts 54 to a frame frame 56. With their bottom ends, the frame beams 52 form a receiving structure 58, can be applied to the cargo. In the embodiment described here, the receiving structure 58 and a total of the support frame 48 are dimensioned such that the support frame 48 can receive loaded with 60 pallets 60, as shown in the figures dashed lines is indicated. The cargo 60 may be both a single item and multiple items stacked on the pallet 62.

Wie insbesondere in Figur 2 zu erkennen ist, ist an der Innenseite jedes Gestellgerüsts 56 ein Verbindungsblech 64 vorgesehen, dessen Enden 66 seitlich über das entsprechende Gestellgerüst 56 überstehen und welches an dem dem Gestellrahmen 50 des Traggestells 48 benachbarten Endbereich des entsprechenden Gestellgerüsts 56 angeordnet ist.As in particular in FIG. 2 can be seen, on the inside of each rack scaffold 56, a connecting plate 64 is provided, the ends 66 project laterally beyond the corresponding frame stand 56 and which is arranged on the frame frame 50 of the support frame 48 adjacent end portion of the corresponding frame structure 56.

Die Enden 66 der Verbindungsbleche 64 sind jeweils über teleskopartige Dämpfungsglieder 68 mit der Stirnfläche eines Querholms 44 der Trägerstruktur 42 verbunden. Die Verbindungsenden der Dämpfungsglieder 68 sind an dem Querholm 44 der Trägerstruktur 42 um eine Achse 70 und an dem Verbindungsblech 64 um eine Achse 72 verschwenkbar, wobei beide Achsen 70, 72 parallel zur Transportrichtung T verlaufen.The ends 66 of the connecting plates 64 are each connected via telescopic damping members 68 with the end face of a cross member 44 of the support structure 42. The connecting ends of the damping members 68 are pivotable on the transverse member 44 of the support structure 42 about an axis 70 and on the connecting plate 64 about an axis 72, wherein both axes 70, 72 are parallel to the transport direction T.

Mittig an der Stirnseite des in Figur 2 zu erkennenden Querholmes 44 der Trägerstruktur 42 ist eine Zylinderhalterung 74 angeflanscht, mittels der ein Hydraulikzylinder 76 um eine senkrecht auf die Transportrichtung T stehende horizontale Achse 78 verschwenkbar befestigt ist. Bei dem Hydraulikzylinder 76 handelt es sich um einen üblichen Kolbenzylinder mit einem Zylindergehäuse und einer an dem Kolben angebrachten Kolbenstange 84, die aus dem Zylindergehäuse austritt. Die beiden fluidgefüllten Druckräume des Hydraulikzylinders 76 kommunizieren über eine mit einem Drosselventil 80 versehene Fluidleitung 82.Center on the front of the in FIG. 2 to be recognized Querholmes 44 of the support structure 42, a cylinder holder 74 is flanged by means of a hydraulic cylinder 76 is pivotally mounted about a perpendicular to the transport direction T horizontal axis 78. The hydraulic cylinder 76 is a conventional piston cylinder having a cylinder housing and a piston rod 84 attached to the piston that exits the cylinder housing. The two fluid-filled pressure chambers of the hydraulic cylinder 76 communicate via a fluid line 82 provided with a throttle valve 80.

Der Hydraulikzylinder 76 ist derart in der Zylinderhalterung 74 angeordnet, daß seine Kolbenstange 84 in Richtung auf den Tragholm 24 weist. Das außenliegende Ende der Kolbenstange 84 des Hydraulikzylinders 76 ist über eine Halterung 86 verschwenkbar mit der Stirnseite des Endbereichs 28 des Tragholms 24 verbunden, wobei die Gelenkachse 88 senkrecht auf der Transportrichtung T und auf der Papierebene steht. Das Drosselventil 80 des Hydraulikzylinders 76 ist über eine Leitung 90 mit einer Steuereinrichtung 92 verbunden, die hier an einem Antriebswagen 20 angeordnet ist. Die Steuereinrichtung 92 empfängt über eine weitere Leitung (nicht dargestellt) Signale von einer in Figur 2 zu erkennenden Sensoreinheit 96, welche an einem Antriebswagen 20 derart angebracht ist, daß sie eine entlang der Tragschiene 16 angeordnete Codierung 94 auf einer Codeschiene 95 (vgl. Figur 2) lesen kann und welche der gelesenen Codierung 94 entsprechende Signale an die Steuereinrichtung 92 sendet.The hydraulic cylinder 76 is so in the cylinder holder 74 arranged that its piston rod 84 points in the direction of the support beam 24. The outer end of the piston rod 84 of the hydraulic cylinder 76 is connected via a holder 86 pivotally connected to the end face of the end portion 28 of the support beam 24, wherein the hinge axis 88 is perpendicular to the transport direction T and on the paper plane. The throttle valve 80 of the hydraulic cylinder 76 is connected via a line 90 to a control device 92, which is arranged here on a drive carriage 20. The controller 92 receives signals from an in-line via another line (not shown) FIG. 2 to be recognized sensor unit 96 which is mounted on a drive carriage 20 such that it has a arranged along the support rail 16 coding 94 on a code rail 95 (see. FIG. 2 ) and which of the read coding 94 sends corresponding signals to the control device 92.

An jeweils einer Stirnflächen der Querholme 44 der Trägerstruktur 42 sind Rollen 98 angebracht, welche jeweils auf einer senkrecht auf der Transportrichtung T stehenden horizontalen Achse gelagert sind.On each of an end faces of the transverse bars 44 of the support structure 42 rollers 98 are mounted, which are each mounted on a perpendicular to the transport direction T horizontal axis.

Diese dienen der Seitenführung, wenn die Tragschiene 16 in der horizontalen Ebene eine Krümmung aufweist, so daß die Bahn des Hängebahnsystems 10 in einer Kurve verläuft. Dazu sind in solchen hier nicht dargestellten Kurvenbereichen des Hängebbahnsystems 10 seitliche Führungsschienen vorgesehen, in welche die Rollen 98 beim Eintritt des Traggestells 98 in den Kurvenbereich einfahren.These serve the side guide when the support rail 16 has a curvature in the horizontal plane, so that the path of the monorail system 10 extends in a curve. For this purpose, 10 side guide rails are provided in such not shown here curve areas of the overhead track system, in which the rollers 98 enter at the entrance of the support frame 98 in the curve area.

An der Unterseite des Tragholmes 24 sind zwei Gummipuffer 100 vorgesehen, auf die nachstehend noch eingegangen wird.At the bottom of the support Holmes 24 two rubber buffer 100 are provided, which will be discussed below.

An dem bezogen auf die hier angenommene Transportrichtung T vorderen Antriebswagen 20 ist ein in Transportrichtung wirkender Infrarot-Abstandssensor 102 angebracht. An dem hinteren Antriebswagen 20 ist eine entgegen der Transportrichtung weisende Reflektorplatte 104 angebracht. An dem vorderen Antriebswagen 20 ist darüber hinaus ein in Transportrichtung T weisender passiver Abstandshalter 106 in Form eines Stoßdämpfers vorgesehen.An infrared distance sensor 102 acting in the transport direction is attached to the front drive carriage 20, which is assumed to be the transport direction T assumed here. On the rear drive carriage 20, a counter to the transport direction facing reflector plate 104 is attached. In addition, a passive spacer 106 in the form of a shock absorber 106, which points in the direction of transport T, is provided on the front drive carriage 20.

Das oben beschriebene Hängebahnsystem 10 funktioniert wie folgt:The monorail system 10 described above functions as follows:

Zum Transport von Gegenständen wird das Traggestell 48 in üblicher Weise mit dem Transportgut 60 beladen. Die Elektromotoren 22 werden zeitgleich und aufeinander abgestimmt eingeschaltet, so daß sich das gesamte Fördergehänge mit dem beladenen Transportgestell 48 in Transportrichtung T in Bewegung setzt.For the transport of objects, the support frame 48 is loaded in the usual manner with the transported goods 60. The electric motors 22 are switched on at the same time and coordinated with each other, so that the entire conveyor belt with the loaded transport frame 48 in the transport direction T is in motion.

Die beiden Druckkammern des Hydraulikzylinders 76 sind, wie oben erwähnt, fluidgefüllt und kommunizieren über die Fluidleitung 82. Wird also auf die Kolbenstange 84 eine Kraft ausgeübt, die bewirkt, daß diese in den Zylinder des Hydraulikzylinders 76 hineingedrückt oder aus diesem herausgezogen wird, so ist eine solche Bewegung der Kolbenstange 82 möglich, wenn das Drosselventil 80 der Leitung 82 im Strömungsweg des Fluids von einer Kammer des Hydraulikzylinders 76 zur anderen geöffnet ist.As mentioned above, the two pressure chambers of the hydraulic cylinder 76 are fluid-filled and communicate via the fluid line 82. Thus, if a force is exerted on the piston rod 84 causing it to be pushed into or withdrawn from the cylinder of the hydraulic cylinder 76, then such movement of the piston rod 82 is possible when the throttle valve 80 of the conduit 82 is opened in the flow path of the fluid from one chamber of the hydraulic cylinder 76 to the other.

Bei geöffnetem Ventil 80 kann somit die Trägerstruktur 42, und folglich das damit verbundene Traggestell 48, um die Schwenkachse 36 des Gelenks 34 verschwenken.With the valve 80 open, the support structure 42, and consequently the support frame 48 connected thereto, can thus pivot about the pivot axis 36 of the articulation 34.

Ein Verschwenken des Traggestells 48 ist wünschenswert, wenn das Hängebahnsystem 10 Abschnitte aufweist, in denen die Tragschiene 16 gegenüber einer horizontalen Ebene geneigt ist, wie es in den Figuren 3 und 4 dargestellt ist. Dabei verläuft die Streckenführung des Hängebahnsystems 10 in Figur 3 in der hier gewählten Transportrichtung T nach oben, wogegen sie in Figur 4 nach unten gerichtet ist.A pivoting of the support frame 48 is desirable when the monorail system 10 has sections in which the mounting rail 16 is inclined with respect to a horizontal plane, as in the Figures 3 and 4 is shown. The routing of the overhead conveyor system 10 in FIG. 3 in the transport direction T selected here upwards, whereas it is directed downward in Figure 4.

In solchen Abschnitten ist es notwendig, daß sich das mit Transportgut beladene Traggestell 48 gegenüber der Vertikalen ausrichten kann. Wäre das Traggestell 48 starr und nicht gelenkig mit dem Tragholm 24 und somit mit den Antriebsmitteln 22 verbunden, käme es zu einer Schieflage des Transportguts 60 gegenüber der Vertikalen. Je nach Neigungsgrad des geneigten Abschnitts des Hängebahnsystems 10 wäre es dann möglich, daß das Transportgut 60 aufgrund der Schwerkraft verkippt und aus dem Traggestell 48 herausfällt. Diese Gefahr besteht insbesondere dann, wenn es sich bei dem Transportgut 60 um lose aufeinander gestapelte einzelne Gegenstände handelt.In such sections, it is necessary that the loaded with cargo carrying frame 48 can align with the vertical. If the support frame 48 were rigidly and non-hingedly connected to the carrier beam 24 and thus to the drive means 22, there would be a misalignment of the transport material 60 with respect to the vertical. Depending on the degree of inclination of the inclined portion of the monorail system 10, it would then be possible that the cargo 60 is tilted due to gravity and falls out of the support frame 48. This danger exists in particular when the item to be transported 60 is individual items stacked loosely on one another.

Wie in Figur 3 zu erkennen ist, bewegen sich die mit der Kolbenstange 82 des Hydraulikzylinders 76 verbundene Halterung 86 und die den Hydraulikzylinder 76 tragende Zylinderhalterung 74 aufeinander zu, wenn die Tragschiene 16 in Transportrichtung T nach oben verläuft. Dabei wird die Kolbenstange 82 in den Zylinder des Hydraulikzylinders 76 hineingeschoben, wobei Fluid aus der unteren Kammer über die Fluidleitung 82 in die obere Kammer des Hydraulikzylinders 76 gedrückt wird.As in FIG. 3 1, the support 86 connected to the piston rod 82 of the hydraulic cylinder 76 and the cylinder support 74 carrying the hydraulic cylinder 76 move toward one another when the support rail 16 extends upwards in the transporting direction T. In this case, the piston rod 82 is pushed into the cylinder of the hydraulic cylinder 76, whereby fluid from the lower chamber via the fluid line 82 is pressed into the upper chamber of the hydraulic cylinder 76.

Verläuft die Tragschiene 16 in Transportrichtung T nach unten, wie es in Figur 4 gezeigt ist, kehren sich die Verhältnisse um und die Kolbenstange 82 wird aus dem Zylinder des Hydraulikzylinders 76 herausgezogen, wobei Fluid von der oberen Kammer in die untere Kammer des Hydraulikzylinders 76 gedrückt wird.Runs the support rail 16 in the transport direction T down, as it is in FIG. 4 is shown, the conditions reverse and the piston rod 82 is pulled out of the cylinder of the hydraulic cylinder 76, wherein Fluid from the upper chamber into the lower chamber of the hydraulic cylinder 76 is pressed.

Das Verschwenken des Traggestells 48 erfolgt allein aufgrund der Gewichtskraft des Transportguts 60. Durch das Gelenk 34 ist also gewährleistet, daß das Transportgut in einem geneigten Streckenabschnitt des Hängebahnsystems 10 im wesentlichen zur Vertikalen ausgerichtet verbleibt, wodurch ein Verkippen des Transportguts 60 verhindert wird.The pivoting of the support frame 48 is carried out solely on the basis of the weight of the cargo 60. By the joint 34 is thus ensured that the cargo remains aligned in an inclined section of the monorail system 10 substantially to the vertical, whereby tilting of the cargo 60 is prevented.

In dem Bereich des Hängebahnsystems 10, in dem die Tragschiene 16 von einem horizontalen Abschnitt in einen geneigten Abschnitt übergeht, verringert sich die Transportgeschwindigkeit in horizontaler Richtung. Dadurch kann das Traggestell 48 zunächst um die Schwenkachse 36 des Gelenks 34 aus der vertikalen Ausrichtung heraus verschwenken, und zwar in Transportrichtung T. Diese erste Schwenkbewegung ist gewünscht, da so die resultierenden Kräfte kompensiert werden.In the area of the monorail system 10 in which the mounting rail 16 transitions from a horizontal section to an inclined section, the transport speed decreases in the horizontal direction. As a result, the support frame 48 can first pivot out of the vertical alignment about the pivot axis 36 of the articulation 34, specifically in the transport direction T. This first pivoting movement is desired since this compensates for the resulting forces.

Im Anschluß an diese erste Schwenkbewegung wird das Traggestell 48 jedoch in die zur ersten Schwenkrichtung entgegengesetzte Richtung über die vertikale Achse hinaus verschwenkt. Das Traggestell 48 würde dann eine Schwingbewegung über die vertikale Achse hinaus ausführen und dadurch ins Schwingen geraten, wodurch das Transportgut 60 verkippen könnte.Following this first pivotal movement, however, the support frame 48 is pivoted in the opposite direction to the first pivoting direction beyond the vertical axis. The support frame 48 would then perform a swinging movement beyond the vertical axis and thereby vibrate, whereby the cargo 60 could tilt.

Um solche unkontrollierten Schwingungen zu verhindern, ist in der Fluidleitung 82 des Hydraulikzylinders 76 das Drosselventil 80 vorgesehen.In order to prevent such uncontrolled vibrations, the throttle valve 80 is provided in the fluid line 82 of the hydraulic cylinder 76.

Fährt das Traggestell 48 in einen Übergangsbereich des Hängebahnsystems 10 zwischen horizontalem und geneigten Verlauf der Tragschiene 16 ein, so wird der Durchlaßquerschnitt des Ventils 80 über die Steuereinrichtung 92 derart eingestellt, dass beim Überströmen des Fluids von einer Kammer des Hydraulikzylinders 76 zur anderen eine Dämpfung erfolgt, die Schwenkbewegung des Traggestells 48 also gebremst wird. Ein Schwingen des Traggestells 48 über die Vertikale hinaus - nach der oben angesprochenen ersten Schwenkbewegung - wird somit verhindert.Moves the support frame 48 in a transition region of the overhead conveyor system 10 between horizontal and inclined Course of the support rail 16, the passage cross-section of the valve 80 is adjusted via the control device 92 such that when overflowing the fluid from one chamber of the hydraulic cylinder 76 to the other a damping takes place, the pivoting movement of the support frame 48 is thus braked. A swinging of the support frame 48 beyond the vertical - after the above-mentioned first pivotal movement - is thus prevented.

Ein Verschwenken des Traggestells 48 um die Schwenkachse 36 ist somit möglich, wogegen ein periodisches Schwingen desselben um die Schwenkachse 36 über die Vertikale hinaus unterbunden ist.A pivoting of the support frame 48 about the pivot axis 36 is thus possible, while a periodic oscillation of the same about the pivot axis 36 is prevented beyond the vertical addition.

Falls bereits die erste Schwenkbewegung des Traggestells unerwünscht ist, so kann zur Vermeidung derselben die Transportgeschwindigkeit des Hängebahnsystems 10 angepaßt werden. Fährt das Traggestell 48 entsprechend langsam in einen Übergangsbereich zwischen einem horizontalen und einem geneigten Abschnitt der Tragschiene 16 ein, so kommt es nicht zu einer ersten Schwenkbewegung des Traggestells, vielmehr bleibt es durch die vertikal nach unten wirkende Gewichtskraft zur Vertikalen ausgerichtet, indem es um die Schwenkachse 36 verschwenkt.If already the first pivotal movement of the support frame is undesirable, it can be adapted to avoid the same transport speed of the overhead conveyor system 10. If the support frame 48 moves correspondingly slowly into a transitional region between a horizontal and an inclined section of the support rail 16, then there is no first pivotal movement of the support frame, but it remains aligned by the vertically downwardly acting weight force to the vertical, by about the Swivel axis 36 pivots.

Es bleibt bei einem derartigen Betrieb des Hängebahnsystems 10 das Drosselventil 80 geschlossen und das Traggestell 48 somit in seiner Vertikalstellung arretiert, wenn das Traggestell 48 sich in einem horizontalen oder in einem mit konstanter Steigung geneigten Abschnitt der Tragschiene 16 befindet. Das Drosselventil 80 wird lediglich geöffnet, während sich das Traggestell 48 in einem Übergangsbereich zwischen den Abschnitten befindet, um die vertikale Ausrichtung zu ermöglichen.It remains in such an operation of the monorail system 10, the throttle valve 80 is closed and the support frame 48 thus locked in its vertical position when the support frame 48 is in a horizontal or inclined in a constant pitch portion of the support rail 16. The throttle valve 80 is merely opened while the support frame 48 is in a transitional area between the sections to allow for vertical alignment.

Dadurch kann die Bewegung des Traggestells 48 angehalten bzw. wieder aufgenommen werden, ohne dass es zu einem Schwingen des Traggestells 48 durch Brems- oder Beschleunigungskräfte kommt.Thereby, the movement of the support frame 48 can be stopped or resumed without causing the support frame 48 to vibrate due to braking or acceleration forces.

Für eine gezielte Ansteuerung des Ventils 80 arbeitet die Steuereinrichtung 92 mit der Sensoreinheit 96 zusammen, welche die entlang der Tragschiene 16 angebrachte Codierung 94 ausliest. Diese Codierung 94 kann beispielsweise eine Positionsinformation umfassen, so dass die Steuereinrichtung 92 entsprechend der Position des Traggestells 48 bei Einfahren in einen Übergangsbereich des Hängebahnsystems 10 das Ventil 80 des Hydraulikzylinders 76 ansteuern kann. Darüber hinaus kann die Steuereinrichtung 92 mit Daten programmiert sein, welche beispielsweise das Gewicht des geförderten Transportguts 60 umfassen, um auf der Grundlage dieser Daten die von dem Gewicht des Transportguts 60 beeinflusste Verschwenkung bzw. das Schwingen des Traggestells 48 entsprechend zu dämpfen bzw. durch ein Verschließen des Ventils 80 vollständig zu unterbinden.For targeted control of the valve 80, the control device 92 cooperates with the sensor unit 96, which reads the attached along the mounting rail 16 coding 94. This coding 94 may, for example, comprise position information, so that the control device 92 can control the valve 80 of the hydraulic cylinder 76 in accordance with the position of the support frame 48 when entering a transition region of the monorail system 10. In addition, the controller 92 may be programmed with data including, for example, the weight of the conveyed conveyed 60 to attenuate on the basis of this data, influenced by the weight of the transported material 60 pivoting or the swing of the support frame 48 respectively Closing the valve 80 completely stop.

Ist das Traggestell 48 nicht mit Transportgut 60 beladen, so ist es nicht nötig, ein Schwingen des Traggestells 48 um die Schwenkachse 36 des Gelenks 34 über die Vertikale hinaus zu unterbinden oder zu dämpfen. Um jedoch über den Bewegungsweg der Kolbenstange 84 des Hydraulikzylinders 76 hinausgehende Schwingbewegungen des Traggestells 48 zu verhindern, sind an der Unterseite des Tragholmes 24 die zwei Gummipuffer 100 vorgesehen. Diese sind so ausgerichtet, dass die Trägerstruktur 42 bei einem bestimmten Ausmaß der Verschwenkung um die Schwenkachse 36 des Gelenks 34 gegen einen der Gummipuffer 100 anstößt, wie dies in den Figuren 3 und 4 gut zu erkennen ist.If the support frame 48 is not loaded with goods to be transported 60, it is not necessary to prevent oscillation of the support frame 48 about the pivot axis 36 of the joint 34 beyond the vertical addition or to attenuate. However, in order to prevent beyond the movement path of the piston rod 84 of the hydraulic cylinder 76 swinging movements of the support frame 48, the two rubber buffer 100 are provided on the underside of the support Holmes 24. These are aligned so that the support structure 42 at a certain extent of pivoting about the pivot axis 36 of the hinge 34 abuts against one of the rubber buffer 100, as shown in the Figures 3 and 4 easy to recognize.

Durch die Verbindung des Traggestells 48 mit der TrägerStruktur 42 über die Scharniere 46 kann das Traggestell 48 bezogen auf die Transportrichtung T seitlich verschwenken, wenn die Tragschiene 16 in einer Kurve verläuft. Dabei bewegt sich die Aufnahmestruktur 58 des Traggestells 48 durch die Fliehkraft nach außen und das Tragestell 48 legt sich bezogen auf eine parallel zu dem Mittelholm 40 der Trägerstruktur 42 verlaufende vertikale Ebene schräg.By the connection of the support frame 48 with the support structure 42 via the hinges 46, the support frame 48 can pivot laterally relative to the transport direction T, when the support rail 16 extends in a curve. In this case, the receiving structure 58 of the support frame 48 moves by the centrifugal force to the outside and the support frame 48 lies down with respect to a parallel to the central spar 40 of the support structure 42 extending vertical plane obliquely.

Dadurch wird verhindert, dass das Transportgut 60 in einer Kurve der Tragschiene 16 seitlich aus dem Traggestell 48 herausfällt. Die Dämpfungsglieder 68 verhindern dabei ein seitliches Pendeln des Traggestells 48.This prevents that the transported material 60 falls laterally out of the support frame 48 in a curve of the support rail 16. The attenuators 68 thereby prevent a lateral oscillation of the support frame 48th

Der Infrarot-Abstandssensor 102 des Fördergehänges arbeitet mit der Reflektorplatte 104 eines zweiten, vorausfahrenden Fördergehänges zusammen. Unterschreitet der Abstand zum vorausfahrenden Fördergehänge einen vorgegebenen Sicherheitsabstand, so werden die Elektromotoren 22 des Fördergehänges entsprechend angesteuert, so dass sich seine Geschwindigkeit verringert und der vorgegebene Sicherheitsabstand wieder eingehalten wird.The infrared distance sensor 102 of the Fördergehänges cooperates with the reflector plate 104 of a second, preceding Fördergehänges. If the distance to the conveyor hanger in front moves below a predetermined safety distance, then the electric motors 22 of the hanger are actuated accordingly so that its speed is reduced and the predetermined safety distance is maintained again.

Für den Fall, dass diese Sicherheitseinrichtung nicht fehlerfrei arbeitet, ist an dem vorderen Antriebswagen 20 der in Transportrichtung T weisende Abstandshalter 106 vorgesehen. Das Fördergehänge kann dadurch nur so lange näher an ein vorausfahrendes Fördergehänge heranfahren, bis der Abstandshalter 106 an das vorausfahrende Fördergehänge anstößt. Der als Stoßdämpfer ausgebildete Abstandshalter 106 dämpft dabei zusätzlich den Aufprall.In the event that this safety device does not operate faultlessly, the spacer 106 pointing in the transporting direction T is provided on the front drive carriage 20. As a result, the conveyor hanger can only move closer to a preceding conveyor hanger until the spacer 106 abuts the preceding conveyor hanger. The designed as a shock absorber spacer 106 additionally attenuates the impact.
