Bei bekannten Transportvorrichtungen können beispielsweise beim Anfahren oder Abbremsen und insbesondere beim Transport von schweren Werkstücken starke Kräfte auf die Transportvorrichtung einwirken, was zu einer Verkürzung der Lebensdauer der Transportvorrichtung und/oder des Transportsystems bzw. Teilen davon führen kann.In known transport devices, for example, when starting or braking and in particular during transport of heavy workpieces strong forces acting on the transport device, which can lead to a shortening of the life of the transport device and / or the transport system or parts thereof.

Aufgabe der vorliegenden Erfindung ist es, eine Transportvorrichtung bereitzustellen, die im Hinblick auf ihre Stabilität und Zuverlässigkeit weiterentwickelt ist.The object of the present invention is to provide a transport device which is further developed with regard to its stability and reliability.

Diese Aufgabe wird gelöst durch eine Transportvorrichtung der eingangs genannten Art, bei welcher

  • d) der mindestens eine Zugwagen und die Tragstruktur mittels einer Pendelvorrichtung miteinander verbunden sind.
This object is achieved by a transport device of the type mentioned, in which
  • d) the at least one carriage and the support structure are interconnected by means of a shuttle.

By the pendulum device 65, the support structure 31, 45, 46, 47, 48 relative to the carriage 40 in the conveying direction 91 and opposite commute. The connection of the shuttle 65 with the coaches 40 and the connection of the shuttle 65 with the support structure 31, 45, 46, 47, 48 is preferably articulated as shown in the example.

Im gezeigten Beispiel weist die Pendelvorrichtung 65 eine Stange 60 mit zwei Befestigungselementen 61, 62 auf. Die Stange 60 verbindet den Zugwagen 40 mit dem Tragarm 47 der Vorläufereinheit 6. Zur Verbindung der Stange 60 mit dem Zugwagen 40 ist ein erstes gelenkig ausgebildetes Befestigungselement 61 vorgesehen. Ein weiteres gelenkig ausgebildetes Befestigungselement 62 ist zur Verbindung der Stange 60 der Pendelvorrichtung 65 mit dem Tragarm 47 der Vorläufereinheit 6 der Transportvorrichtung 5 vorgesehen.In the example shown, the pendulum device 65 has a rod 60 with two fastening elements 61, 62.

Another articulated fastener 62 is provided for connecting the rod 60 of the shuttle 65 with the support arm 47 of the precursor unit 6 of the transport device 5.

Um eine funktionsgerechte Pendelbewegung zu ermöglichen kann die Transportvorrichtung 5 beispielsweise drei Drehgelenke 51, 52 mit horizontalen Drehachsen aufweisen, die vorzugsweise wie folgt angeordnet sein können: Zum einen ist der Tragarm 47 der Vorläufereinheit 6 mittels eines Drehgelenks 52 mit der Traverse 45 der Vorläufereinheit 6 verbunden. Weiterhin sind zwei Drehgelenke 51 zur Verbindung der Lasttraverse 31 mit der Tragstruktur 31, 45, 46, 47, 48 vorgesehen, welche zwei Drehgelenke 51 im Bereich der Befestigungsvorrichtungen 37, 38 der Lasttraverse 31 angeordnet sind. Die drei Drehgelenke 51, 52 weisen horizontale Drehachsen auf.In order to enable a functional pendulum movement, the transport device 5, for example, three hinges 51, 52 having horizontal axes of rotation, which may be preferably arranged as follows: First, the support arm 47 of the precursor unit 6 is connected by means of a hinge 52 with the cross member 45 of the precursor unit 6 , Furthermore, two pivot joints 51 are provided for connecting the load cross member 31 to the support structure 31, 45, 46, 47, 48, which two pivot joints 51 are arranged in the region of the fastening devices 37, 38 of the load cross member 31. The three hinges 51, 52 have horizontal axes of rotation.

Um die Transportvorrichtung 5 entlang eines geneigten Schienensystems zu fördern, kann es zweckdienlich sein, alternativ und/oder zusätzlich zu den vorangehend beschriebenen Drehgelenken mit horizontaler Drehachse weitere Drehgelenke mit horizontaler Drehachse vorzusehen. Derartige Drehgelenke sind in der Zeichnung angedeutet, jedoch nicht mit Bezugszeichen versehen. Das Vorsehen von Drehgelenken mit horizontaler Drehachse im Bereich der Tragstruktur 31, 45, 46, 47, 48 der Transportvorrichtung 5 bewirkt ein besonders funktionsgerechtes Verhalten bei Steigungsfahrten, wobei die Lasttraverse 31 um eine horizontale Achse gekippt wird.In order to convey the transport device 5 along an inclined rail system, it may be expedient, alternatively and / or in addition to the previously described rotary joints with a horizontal axis of rotation, to provide further rotary joints with a horizontal axis of rotation. Such hinges are indicated in the drawing, but not provided with reference numerals. The provision of hinges with horizontal axis of rotation in the region of the support structure 31, 45, 46, 47, 48 of the transport device 5 causes a particularly functional behavior when driving uphill, wherein the load cross-piece 31 is tilted about a horizontal axis.

Um ein besonders funktionsgerechtes Verhalten der Transportvorrichtung 5 bei Kurvenfahrten zu bewirken, kann es zweckdienlich sein, Lagerelemente 49 vorzusehen sein, die eine Drehung um eine vertikale Achse ermöglichen. Die Anzahl und Anordnung derartiger mit einer vertikalen Drehachse versehener Lagerelemente 49 ist vorzugsweise angepasst an die Kurvenradien der Schienen 1, 2, die im Transportsystem 80 vorgesehen sind.In order to effect a particularly functional behavior of the transport device 5 when cornering, it may be expedient to provide bearing elements 49, which allow rotation about a vertical axis.

An der Oberseite des Zugwagens 40 der Vorläufereinheit 6 der Transportvorrichtung sind die Koppelvorrichtung 25 und eine Klinke 24 angeordnet. Die Koppelvorrichtung 25 ist mit der Nocke 21 als Mitnehmerelement und mit einem Auflaufhebel 22 versehen. Im gezeigten Beispiel ist die Koppelvorrichtung 25 auf der vorwärts gerichteten Seite des Zugwagens 40 angeordnet, wobei der Auflaufhebel 22 im Beispiel vorderseitig aus dem Zugwagen 40 ragt. Die Klinke 24 kann als Rückhalteklinke für Mitnehmer 11 der Kette 10 vorgesehen sein. Im gezeigten Beispiel ist die Klinke 24 auf der rückwärts gerichteten Seite des Zugwagens 40 angeordnet.At the top of the carriage 40 of the precursor unit 6 of the transport device, the coupling device 25 and a pawl 24 are arranged. The coupling device 25 is provided with the cam 21 as a driver element and with a run-up lever 22. In the example shown, the coupling device 25 is arranged on the forward side of the carriage 40, wherein the run-up lever 22 projects in the example from the front of the carriage 40. The pawl 24 may be provided as a retaining pawl for driver 11 of the chain 10. In the example shown, the pawl 24 is arranged on the rearward side of the carriage 40.

Das als Nocke 21 ausgebildete Mitnehmerelement ist beweglich am Zugwagen 40 angeordnet. In der gezeigten Anordnung ist die Koppelvorrichtung 25 um eine horizontale Achse schwenkbar ausgebildet. Durch ein Schwenken der Koppelvorrichtung 25 wird entsprechend der beispielhaft gezeigten Ausgestaltung sowohl die Position der Nocke 21 als auch die Position des Auflaufhebels 22 verändert.Trained as a cam 21 driver element is movably arranged on the carriage 40. In the arrangement shown, the coupling device 25 is formed pivotable about a horizontal axis. By pivoting the coupling device 25, both the position of the cam 21 and the position of the run-up lever 22 is changed according to the embodiment shown by way of example.

Der die Nachläufereinheit 7 abschließende Tragwagen 42 ist mit einer Auflaufkufe 23 versehen. Die Auflaufkufe 23 ist auf der rückwärts gerichteten Seite des abschließenden Tragwagens 42 angeordnet und ragt im gezeigten Beispiel rückseitig aus dem abschließenden Tragwagens 42.The trailer unit 42 concluding wagons 42 is provided with a runner 23. The runner 23 is arranged on the rearward side of the final support carriage 42 and protrudes in the example shown back from the final support car 42nd

Figur 1 zeigt einen Betriebszustand, bei welchem die Transportvorrichtung 5 stationär ruht, während die Kette 10 sich in Förderrichtung 91 bewegt. Bei dem in Figur 1 gezeigten Betriebszustand ist die Transportvorrichtung 5 nicht mit der Kette 10 gekoppelt und wird nicht von der Kette 10 gefördert. In dem in Figur 1 gezeigten Betriebszustand greift keiner der Mitnehmer 11 der Kette 10 in die Nocke 21 der gezeigten Transportvorrichtung 5 ein. FIG. 1 shows an operating state in which the transport device 5 rests stationary while the chain 10 moves in the conveying direction 91. At the in FIG. 1 shown operating state, the transport device 5 is not coupled to the chain 10 and is not supported by the chain 10. In the in FIG. 1 shown operating state, none of the driver 11 of the chain 10 engages in the cam 21 of the transport device 5 shown.

Nachfolgend werden an Hand der in den Figuren 2 bis 4 gezeigten Beispiele weitere Betriebszustände der Transportvorrichtung 5 beschrieben. Dabei stimmt der strukturelle Aufbau der Transportvorrichtung 5 in den Figuren 2 bis 4 mit dem vorangehend im Zusammenhang mit Figur 1 beschriebenen Aufbau der Transportvorrichtung 5 überein.Below are on hand in the FIGS. 2 to 4 Examples shown further operating states of the transport device 5 described. In this case, the structural design of the transport device 5 is correct in the FIGS. 2 to 4 with the preceding in connection with FIG. 1 described structure of the transport device 5 match.

Figur 2 zeigt einen Betriebszustand, bei dem ein Mitnehmer 11 der Kette 10, welche kontinuierlich in Förderrichtung 91 bewegt wird, die Nocke 21 kontaktiert hat. Der beim Kontaktieren erfolgende Stoß des Mitnehmers 11 auf die Nocke 21 wird durch die Pendelvorrichtung 65 aufgenommen, da der Zugwagen 40 sich zunächst in Förderichtung 91 bewegen kann. Dabei wird die Lasttraverse 31 in Richtung des Pfeils 92 angehoben. Mit der Lasttraverse 31 werden im gezeigten Beispiel auch das Traggestell 32 und das Transportgut 30 angehoben. Durch das Anheben in Richtung des Pfeils 92 wird Stoßenergie umgewandelt. Derart kann die Auswirkung stoßbedingter Kräfte und stoßbedingter Verschleiß gegenüber aus dem Stand der Technik bekannten Transportvorrichtungen gemindert werden. FIG. 2 shows an operating state in which a driver 11 of the chain 10, which is moved continuously in the conveying direction 91, the cam 21 has contacted. The impact of the cam 11 on the cam 21 occurring during the contacting is absorbed by the pendulum device 65, since the carriage 40 can initially move in the direction of conveyance 91. In this case, the load cross member 31 is raised in the direction of the arrow 92. In the example shown, the support frame 32 and the transported goods 30 are also lifted with the load crossmember 31. Lifting in the direction of arrow 92 converts impact energy. In this way, the effect of impact forces and impact related wear can be reduced compared to known from the prior art transport devices.

Durch das in Figur 2 dargestellte Anheben der Lasttraverse 31 in Richtung des Pfeils 92 verlängert sich der Abstand zwischen dem Zugwagen 40 der Transportvorrichtung 5 und den Tragwagen 41 der Vorläufereinheit 6, wobei sich der Abstand zwischen den Tragwagen 41 der Vorläufereinheit 6 und den Tragwagen 42 der Nachläufereinheit 7 geringfügig verkürzt. Im gezeigten Beispiel wird die Stange 60 der Pendelvorrichtung 65 relativ zum Zugwagen 40 entgegen der Förderrichtung 91 bewegt.Through the in FIG. 2 shown lifting the load cross member 31 in the direction of the arrow 92, the distance between the carriage 40 of the transport device 5 and the carrier car 41 of the precursor unit 6 extends, wherein the distance between the carrier car 41 of the precursor unit 6 and the car 42 of the trailer unit 7 is slightly shortened. In the example shown, the rod 60 of the shuttle 65 is moved relative to the carriage 40 against the conveying direction 91.

Figur 3 zeigt einen eingependelten Betriebszustand, wobei sich die Transportvorrichtung 5 in Richtung des Pfeils 93 gemeinsam mit der Kette 10 bewegt. Die Kette 10, welche kontinuierlich in Richtung des Pfeils 91 bewegt wird, und die Transportvorrichtung 5 bewegen sich mit gleicher Geschwindigkeit. FIG. 3 shows a eingependelten operating condition, wherein the transport device 5 moves in the direction of the arrow 93 together with the chain 10. The chain 10, which is continuously moved in the direction of the arrow 91, and the transport device 5 move at the same speed.

Der eingependelte Zustand gemäß Figur 3 wird gegenüber dem in Figur 2 gezeigten Zustand nach Ablauf einer Zeitspanne erreicht, die von verschiedenen Faktoren abhängen kann. Derartige Faktoren sind z.B. die Stoßkraft beim Kontaktieren des Mitnehmers 11 der Kette 10 mit dem Mitnehmerelement des Zugwagens 40 bzw. das Gewicht des von der Lasttraverse 31 getragenen Transportguts 30.The settled state according to FIG. 3 is opposite to in FIG. 2 reached state after a period of time, which may depend on various factors. Such factors are, for example, the impact force when contacting the driver 11 of the chain 10 with the driver element of the carriage 40 or the weight of the transported material 30 carried by the load cross member 31.

In dem Betriebszustand, der in Figur 3 gezeigt ist, sind die angetriebene Kette 10 und der Zugwagen 40 der Transportvorrichtung 5 miteinander gekoppelt. Die Kopplung erfolgt durch formschlüssige Verbindung, wobei einer der Mitnehmer 11 der Kette 10 in das Mitnehmerelement, d.h. im gezeigten Beispiel in die Nocke 21, des Zugwagens 40 eingreift.In the operating state in FIG. 3 is shown, the driven chain 10 and the carriage 40 of the transport device 5 are coupled together. The coupling is made by positive connection, wherein one of the drivers 11 of the chain 10 engages in the driver element, ie in the example shown in the cam 21, the carriage 40.

Gemäß Figur 3 ist die Koppelvorrichtung 25 in eine erste Position geschwenkt, in welcher Position sich die Nocke 21 im Bewegungsweg der an der Kette 10 angeordneten Mitnehmer 11 befindet.According to FIG. 3 the coupling device 25 is pivoted to a first position, in which position the cam 21 is located in the path of movement of the driver 11 arranged on the chain 10.

Figur 4 zeigt einen Betriebszustand, in dem die Transportvorrichtung 5 abgebremst wird. Der Bremsvorgang wird im gezeigten Beispiel bedingt durch ein Auflaufen der Transportvorrichtung 5 auf eine weitere Transportvorrichtung 105. Auf der auf der rückwärts gerichteten Seite der weiteren Transportvorrichtung 105 ist eine Auflaufkufe 123 angeordnet, die rückseitig aus dem abschließenden Wagen der weiteren Transportvorrichtung 105 ragt. FIG. 4 shows an operating state in which the transport device 5 is braked. The braking operation is in the example shown due to a running of the transport device 5 on a further transport device 105. On the backward side of the further transport device 105 a runner 123 is arranged, which protrudes from the rear carriage of the further transport device 105 back.

Die weitere Transportvorrichtung 105 kann beispielsweise gleich oder strukturell ähnlich der im Zusammenhang mit Figur 1 näher beschriebenen Transportvorrichtung 5 aufgebaut sein. Daher wird an dieser Stelle auf eine detailliertere Beschreibung der weiteren Transportvorrichtung 105 verzichtet.The further transport device 105 may be constructed, for example, identically or structurally similar to the transport device 5 described in more detail in connection with FIG. Therefore, a more detailed description of the further transport device 105 is omitted here.

Gemäß Figur 4 wird der Bremsvorgang der Transportvorrichtung 5 eingeleitet durch ein Auftreffen des Auflaufhebels 22 der Transportvorrichtung 5 auf die Auflaufkufe 123 der weiteren Transportvorrichtung 105. Die Auflaufkufe 123 wirkt dabei derart auf den Auflaufhebel 22 der Transportvorrichtung 5, dass die Koppelvorrichtung 25 geschwenkt wird. Durch das Schwenken der Koppelvorrichtung 25 wird die formschlüssige Verbindung des Mitnehmers 11 der Kette 10 mit dem als Nocke 21 ausgebildeten Mitnehmerelement der Koppelvorrichtung 25 gelöst. Somit bewirkt der Auflaufhebel 22, dass die Kette 10 und der Zugwagen 40 entkoppelt werden.According to FIG. 4 the braking operation of the transport device 5 is initiated by an impingement of the run-up lever 22 of the transport device 5 on the runner 123 of the further transport device 105. The runner 123 acts on the run-up lever 22 of the transport device 5 so that the coupling device 25 is pivoted. By pivoting the coupling device 25, the positive connection of the driver 11 of the chain 10 is released with the cam element 21 formed as a cam member of the coupling device 25. Thus causes the run-up lever 22, that the chain 10 and the carriage 40 are decoupled.

Wie das in Figur 4 gezeigte Beispiel verdeutlicht, können auch beim Bremsen auftretende Kräfte bzw. dabei Bremsenergie mittels der Pendelvorrichtung 65 vorteilhaft aufgenommen werden, wobei die Lasttraverse 31 in Richtung des Pfeils 94 angehoben wird. Mit der Lasttraverse 31 werden im gezeigten Beispiel auch das Traggestell 32 und das Transportgut 30 angehoben. Durch das Anheben in Richtung des Pfeils 94 wird Bremsenergie umgewandelt. Durch das in Figur 4 dargestellte Anhaben der Lasttraverse 31 in Richtung des Pfeils 94, verkürzt sich der Abstand zwischen dem Zugwagen 40 der Transportvorrichtung 5 und den Tragwagen 41 der Vorläufereinheit 6. Im gezeigten Beispiel wird die Stange 60 der Pendelvorrichtung 65 relativ zum Zugwagen 40 in Richtung des Pfeils 91 bewegt.Like that in FIG. 4 illustrated example, also occurring during braking forces or thereby braking energy can be advantageously absorbed by the shuttle 65, wherein the load cross member 31 is raised in the direction of arrow 94. In the example shown, the support frame 32 and the transported goods 30 are also lifted with the load crossmember 31. By lifting in the direction of arrow 94 braking energy is converted. Through the in FIG. 4 In the example shown, the rod 60 of the shuttle 65 is moved relative to the carriage 40 in the direction of the arrow 91 ,

Gemäß Figur 4 ist die die Koppelvorrichtung 25 in eine zweite Position geschwenkt, in welcher Position sich die Nocke 21 unterhalb des Bewegungswegs der an der Kette 10 angeordneten Mitnehmer 11 befindet. Die Koppelvorrichtung 25 des Zugwagens 40 der Transportvorrichtung 5 kann in dieser zweiten Position nicht von den Mitnehmern 11 der Kette 10 erfasst werden.According to FIG. 4 the coupling device 25 is pivoted to a second position, in which position the cam 21 is located below the path of movement of the driver 11 arranged on the chain 10. The coupling device 25 of the carriage 40 of the transport device 5 can not be detected by the drivers 11 of the chain 10 in this second position.

Alternativ und/oder zusätzlich zu den Auflaufkufen 23, 123, kann das Transportsystem 80 zum Anhalten der Transportvorrichtung 5 bei laufender Kette 10 ein oder mehrere Stopper aufweisen, die in den Figuren nicht näher dargestellt sind. Derartige Stopper können z.B. elektromagnetisch oder elektropneumatisch betätigt werden und beispielsweise mittels Klemmbefestigungen z.B. an der Kettenschiene 1 montiert werden. Mittels derartiger Stopper und/oder mittels der Auflaufkufen 23, 123 können Transportvorrichtungen 5, 105 angehalten, aufeinander nachfolgend gestapelt bzw. wieder vereinzelt werden.Alternatively and / or in addition to the runners 23, 123, the transport system 80 for stopping the transport device 5 while the chain 10 running one or more stoppers, which are not shown in detail in the figures. Such stoppers may e.g. be operated electromagnetically or electropneumatically and, for example by means of clamps, e.g. be mounted on the chain rail 1. By means of such stoppers and / or by means of the runners 23, 123, transport devices 5, 105 can be stopped, successively stacked or separated again.

Die Betriebsgeschwindigkeit der in den Figuren 1 bis 4 gezeigten Kette 10 kann bedarfsgerecht geregelt werden. Im Vergleich zum Stand der Technik ermöglicht die Erfindung höhere Transportgeschwindigkeiten ohne Einbußen hinsichtlich der Betriebssicherheit. Erfindungsgemäß ist ein vergleichsweise kontinuierlicherer Betrieb der Kette 10 möglich.The operating speed of the in FIGS. 1 to 4 shown chain 10 can be controlled as needed. Compared to the prior art, the invention enables higher transport speeds without sacrificing reliability. According to the invention, a comparatively continuous operation of the chain 10 is possible.

Nochmals zusammengefasst können mittels der Pendelvorrichtung 65 im Bereich des Zugwagens 40 auf die Transportvorrichtung 5 wirkende Kräfte aufgenommen werden. Auf diese Weise werden die Stabilität und die Zuverlässigkeit der Transportvorrichtung 5 im Betrieb verbessert. Durch die Pendelvorrichtung 65 kann bei zumindest gleicher oder verbesserter Funktionalität auf das Vorsehen von Komponenten wie z.B. Federn, Elastikpuffern und/oder Hydraulikkomponenten zumindest teilweise verzichtet werden. Gegenüber derartigen bekannten Komponenten ist die oben beschriebene Pendelvorrichtung 65 weniger anfällig für Verschleiß.Summarized again, forces acting on the transport device 5 can be absorbed by means of the pendulum device 65 in the area of the towing vehicle 40. In this way, the stability and reliability of the transport device 5 are improved during operation. By the shuttle device 65 can at least the same or improved functionality on the provision of components such as springs, elastic buffers and / or hydraulic components be at least partially waived. Compared with such known components, the above-described shuttle 65 is less susceptible to wear.
