Die Erfindung betrifft auch ein Transportsystem mit mindestens einer Transportvorrichtung.The invention also relates to a transport system with at least one transport device.

Aus der DE 199 25 836 A1 ist ein als "Power & Free"-Förderer bezeichneter Schleppförderer mit einer Tragschiene, mit einer Kettenschiene und mit mindestens einer Transportvorrichtung bekannt, wobei die Transportvorrichtung einen in Bewegungsrichtung vorauseilenden Vorläufer und einen in Bewegungsrichtung nacheilenden Nachläufer aufweist. Gemäß der DE 199 25 836 A1 besitzen der Vorläufer und der Nachläufer jeweils einen Mitnehmer, wobei in der Kettenschiene des Schleppförderers eine Schleppkette geführt ist, die eine Vielzahl von Kettenmitnehmern trägt, die mit den Mitnehmern der Transportvorrichtung in einer Mitnahmeposition zusammenwirken.From the DE 199 25 836 A1 a towing conveyor known as a "Power &Free" conveyor with a carrier rail, with a chain rail and with at least one transport device is known, the transport device having a forerunner that leads in the direction of movement and a follower that lags behind in the direction of movement. According to the DE 199 25 836 A1 the forerunner and the follower each have a driver, with a drag chain being guided in the chain rail of the drag conveyor, which carries a large number of chain drivers which interact with the drivers of the transport device in a driving position.

Solche Transportvorrichtungen sind ebenso aus der EP 2 703 244 A1 bekannt.Such transport devices are also from EP 2 703 244 A1 known.

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 the case of known transport devices, strong forces can act on the transport device, for example when starting up or braking and in particular when transporting heavy workpieces, which leads to a shortening of the service life 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 has been further developed with regard to its stability and reliability.

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

  • c) der mindestens eine Zugwagen und die Tragstruktur mittels einer Pendelvorrichtung miteinander verbunden sind, wobei
  • d) die Tragstruktur eine Lasttraverse aufweist und die Pendelvorrichtung derart zwischen der Lasttraverse und dem mindestens einen Zugwagen angeordnet ist, dass Energie, die dem Zugwagen bei einem Stoß zugeführt wird, in ein Anheben der Lasttraverse umwandelbar ist.
This object is achieved by a transport device of the type mentioned in which
  • c) the at least one train carriage and the supporting structure are connected to one another by means of a pendulum device, wherein
  • d) the supporting structure has a load beam and the pendulum device is arranged between the load beam and the at least one towing vehicle such that energy that is supplied to the towing vehicle in the event of an impact can be converted into a lifting of the load beam.

Auf diese Weise können mit Hilfe der Pendelvorrichtung Kräfte aufgenommen werden, die im Bereich des Zugwagens auf die Transportvorrichtung wirken. Dies bewirkt eine höhere Stabilität und Zuverlässigkeit der Transportvorrichtung in bestimmten Betriebszuständen.In this way, with the help of the pendulum device, forces can be absorbed that act on the transport device in the area of the towing vehicle. This brings about greater stability and reliability of the transport device in certain operating states.

Um eine kompakte und besonders stabile Konstruktion zu ermöglichen, kann die Pendelvorrichtung in vorteilhafter Weiterbildung als Stange mit gelenkigen Befestigungselementen ausgebildet sein.In order to enable a compact and particularly stable construction, the pendulum device can be designed in an advantageous development as a rod with articulated fastening elements.

Mit Vorteil kann die Stange mittels eines ersten Befestigungselements gelenkig am Zugwagen befestigt sein und mittels eines zweiten Befestigungselements gelenkig an einem Tragarm der Tragstruktur befestigt sein. Die Stabilität und die Zuverlässigkeit können auf diese Weise weiter verbessert werden.The rod can advantageously be fastened in an articulated manner to the towing vehicle by means of a first fastening element and fastened in an articulated manner to a supporting arm of the supporting structure by means of a second fastening element. Stability and reliability can be further improved in this way.

Erfindungsgemäß weist die Tragstruktur der Transportvorrichtung eine Lasttraverse auf, wobei die Pendelvorrichtung derart zwischen der Lasttraverse und dem mindestens einen Zugwagen angeordnet ist, dass Energie, die dem Zugwagen bei einem Stoß zugeführt wird, in ein Anheben der Lasttraverse umwandelbar ist. Hierdurch kann die Transportvorrichtung, beispielsweise auch beim Transport schwerer Transportgüter, betriebssicher beschleunigt bzw. angefahren werden und betriebssicher abgebremst bzw. zum Stillstand gebracht werden.According to the invention, the support structure of the transport device on a load beam, wherein the pendulum device is arranged between the load beam and the at least one tractor that energy to the tractor at a Shock is supplied, can be converted into a lifting of the load beam. As a result, the transport device, for example also when transporting heavy goods to be transported, can be reliably accelerated or started and braked or brought to a standstill in a reliable manner.

Es kann weiterhin zweckmäßig sein, dass die Transportvorrichtung eine Vorläufereinheit und eine Nachläufereinheit aufweist, wobei die Lasttraverse der Tragstruktur mittels einer ersten Befestigungsvorrichtung mit einem Tragarm der Vorläufereinheit und mittels einer zweiten Befestigungsvorrichtung mit einem Tragarm der Nachläufereinheit verbunden ist.It can also be expedient for the transport device to have a front-end unit and a back-end unit, with the load beam of the support structure being connected to a support arm of the front-end unit by means of a first fastening device and to a support arm of the back-end unit by means of a second fastening device.

Um die Betriebssicherheit der Transportvorrichtung weiter zu verbessern, kann der Tragarm der Vorläufereinheit in einem ersten Endbereich mit der Pendelvorrichtung verbunden sein, und in einem zweiten Endbereich mit einer Traverse der Tragstruktur verbunden sein, wobei die Traverse der Tragstruktur von mindestens zwei Tragwagen getragen ist.In order to further improve the operational safety of the transport device, the support arm of the precursor unit can be connected to the pendulum device in a first end area and to a crossbar of the support structure in a second end area, with the crossbar of the support structure being supported by at least two carrier wagons.

Mit Vorteil kann der Zugwagen der Transportvorrichtung mit einer Koppelvorrichtung ausgestattet sein, wobei die Koppelvorrichtung ein Mitnehmerelement ausweist. Derart kann z.B. die Integration in ein Materialflusssystem von hoher Flexibilität ermöglicht werden.Advantageously, the towing vehicle of the transport device can be equipped with a coupling device, with the coupling device having a driver element. In this way, for example, integration into a highly flexible material flow system can be made possible.

Vorzugsweise sind die Wagen der Transportvorrichtung zu einer schienengeführten Verwendung ausgebildet. Auf diese Weise wird eine Betriebsweise begünstigt, die weniger für Störungen anfällig ist.The carriages of the transport device are preferably designed for rail-guided use. In this way, a mode of operation is favored which is less susceptible to disturbances.

Die Aufgabe der Erfindung wird auch gelöst durch ein Transportsystem mit mindestens einer Transportvorrichtung, die gemäß der Erfindung oder gemäß einer Ausführung der Erfindung ausgebildet ist, wobei das Transportsystem ein Schienensystem mit mindestens einer Tragschiene für die Wagen der mindestens einen Transportvorrichtung aufweist. Auf diese Weise wird ein Transportsystem bereitgestellt, das sich durch hohe Zuverlässigkeit und Betriebssicherheit auszeichnet.The object of the invention is also achieved by a transport system with at least one transport device according to the invention or according to an embodiment of the invention is formed, wherein the transport system has a rail system with at least one support rail for the carriage of the at least one transport device. In this way, a transport system is provided that is characterized by high reliability and operational safety.

In einer besonders robusten Ausgestaltung kann das Transportsystem zum Fördern der mindestens einen Transportvorrichtung eine mit einem Antrieb gekoppelte Kette aufweisen.In a particularly robust embodiment, the transport system for conveying the at least one transport device can have a chain coupled to a drive.

Um einen möglichst kontinuierlichen Betrieb der Kette zu ermöglichen, kann es von Vorteil sein, dass die Kette mit mehreren Mitnehmern ausgestattet ist, von denen ein Mitnehmer mit der Koppelvorrichtung des Zugwagens der mindestens einen Transportvorrichtung koppelbar ist.In order to enable the chain to be operated as continuously as possible, it can be advantageous for the chain to be equipped with several carriers, one of which carriers can be coupled to the coupling device of the towing vehicle of the at least one transport device.

Die Lasttraverse 31 der Transportvorrichtung 5 wird von dem Tragarm 47 der Vorläufereinheit 6 und von dem Tragarm 48 der Nachläufereinheit 7 getragen. Im gezeigten Beispiel bildet die Lasttraverse 31 mit den Tragarmen 47, 48 und den Traversen 45, 46 eine Tragstruktur der Transportvorrichtung 5 aus, vermittels welcher die Tragwagen 41, 42 das Traggestell 32 tragen.The load beam 31 of the transport device 5 is carried by the support arm 47 of the front-end unit 6 and by the support arm 48 of the rear-end unit 7 . In the example shown, the load traverse 31 with the support arms 47, 48 and the traverses 45, 46 forms a support structure of the transport device 5, by means of which the support carriages 41, 42 support the support frame 32.

Zwischen dem Zugwagen 40 und der Tragstruktur 31, 45, 46, 47, 48 der Transportvorrichtung 5 ist eine Pendelvorrichtung 65 vorgesehen. Durch die Pendelvorrichtung 65 kann die Tragstruktur 31, 45, 46, 47, 48 gegenüber dem Zugwagen 40 in Förderrichtung 91 und entgegengesetzt pendeln. Die Verbindung der Pendelvorrichtung 65 mit dem Zugwagen 40 und die Verbindung der Pendelvorrichtung 65 mit der Tragstruktur 31, 45, 46, 47, 48 ist wie im Beispiel gezeigt, vorzugsweise jeweils gelenkig ausgeführt.A pendulum device 65 is provided between the towing vehicle 40 and the support structure 31 , 45 , 46 , 47 , 48 of the transport device 5 . By means of the pendulum device 65, the support structure 31, 45, 46, 47, 48 can pendulum in relation to the towing vehicle 40 in the conveying direction 91 and in the opposite direction. The connection of the pendulum device 65 to the towing vehicle 40 and the connection of the pendulum device 65 to the support structure 31, 45, 46, 47, 48 is, as shown in the example, preferably articulated.

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.

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 can have, for example, three rotary joints 51, 52 with horizontal axes of rotation, which can preferably be arranged as follows: On the one hand, the support arm 47 of the front-end unit 6 is connected to the crossbar 45 of the front-end unit 6 by means of a rotary joint 52 . Furthermore, two rotary joints 51 are provided for connecting the load beam 31 to the supporting structure 31, 45, 46, 47, 48, which two rotary joints 51 are arranged in the region of the fastening devices 37, 38 of the load beam 31. The three rotary joints 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 can be expedient to provide further rotary joints with a horizontal axis of rotation as an alternative and/or in addition to the previously described rotary joints with a horizontal axis of rotation. Such swivel joints are indicated in the drawing, but are not provided with reference symbols. The provision of rotary joints with a horizontal axis of rotation in the area of the support structure 31, 45, 46, 47, 48 of the transport device 5 results in a particularly functional behavior when driving uphill, with the load beam 31 being 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 bring about a particularly functional behavior of the transport device 5 when cornering, it can be expedient to provide bearing elements 49 which allow rotation about a vertical axis. The number and arrangement of such bearing elements 49 provided with a vertical axis of rotation is preferably adapted to the curve radii of the rails 1 , 2 provided in the transport system 80 are.

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.The coupling device 25 and a pawl 24 are arranged on the upper side of the towing vehicle 40 of the forerunner unit 6 of the transport device. The coupling device 25 is provided with the cam 21 as a driver element and with an overrun lever 22 . In the example shown, the coupling device 25 is arranged on the forward-facing side of the towing vehicle 40 , the overrun lever 22 protruding from the front of the towing vehicle 40 in the example. The pawl 24 can be provided as a retaining pawl for drivers 11 of the chain 10 . In the example shown, the pawl 24 is arranged on the rear-facing side of the towing vehicle 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.The driver element designed as a cam 21 is movably arranged on the towing vehicle 40 . In the arrangement shown, the coupling device 25 is designed to be pivotable about a horizontal axis. By pivoting the coupling device 25, both the position of the cam 21 and the position of the overrun lever 22 are changed in accordance with the configuration shown as an 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 carrier carriage 42 which closes the rear-mounted unit 7 is provided with a run-on skid 23 . The ramp skid 23 is arranged on the rear-facing side of the trailing carrier 42 and, in the example shown, protrudes from the rear of the trailing carrier 42.

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. figure 1 shows an operating state in which the transport device 5 is stationary while the chain 10 moves in the conveying direction 91. At the in figure 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 figure 1 shown operating state engages none of the drivers 11 of the chain 10 in the cam 21 of the shown Transport device 5 a.

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.In the following, on the basis of the Figures 2 to 4 Examples shown further operating states of the transport device 5 are described. The structural design of the transport device 5 agrees in the Figures 2 to 4 with the preceding related to figure 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. figure 2 shows an operating state in which a driver 11 of the chain 10, which is continuously moved in the conveying direction 91, has contacted the cam 21. The impact of the driver 11 on the cam 21 that occurs when the contact is made is absorbed by the pendulum device 65 since the traction carriage 40 can initially move in the conveying direction 91 . In the process, the load beam 31 is raised in the direction of the arrow 92 . In the example shown, the support frame 32 and the item 30 to be transported are also raised with the lifting beam 31 . Lifting in the direction of arrow 92 converts impact energy. In this way, the effect of impact-related forces and impact-related wear can be reduced compared to transport devices known from the prior art.

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 figure 2 lifting the load beam 31 in the direction of the arrow 92 as illustrated, the distance between the towing vehicle 40 of the transport device 5 and the carrying carriage 41 of the front-end unit 6 increases, with the distance between the carrying carriage 41 of the front-end unit 6 and the carrying carriage 42 of the rear-end unit 7 being slightly shortened. In the example shown, the rod 60 of the pendulum device 65 is moved relative to the towing vehicle 40 counter to 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. figure 3 shows a leveled-off operating state, with transport device 5 moving in the direction of arrow 93 moved 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 figure 3 will be compared to the in figure 2 condition shown after a period of time which may depend on various factors. Such factors are, for example, the impact force when the driver 11 of the chain 10 comes into contact with the driver element of the towing vehicle 40 or the weight of the transported goods 30 carried by the load beam 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 condition that figure 3 is shown, the driven chain 10 and the traction carriage 40 of the transport device 5 are coupled to one another. The coupling takes place by means of a form-fitting connection, with one of the drivers 11 of the chain 10 engaging in the driver element, ie in the example shown in the cam 21, of the towing vehicle 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 figure 3 the coupling device 25 is pivoted into a first position, in which position the cam 21 is in the path of movement of the carriers 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. figure 4 shows an operating state in which the transport device 5 is braked. In the example shown, the braking process is caused by the transport device 5 running into another transport device 105. On the rear-facing side of the further transport device 105, a ramp skid 123 is arranged, which protrudes from the back of the trailing carriage of the further transport device 105.

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 can, for example be constructed identically or structurally similar to the transport device 5 described in more detail in connection with FIG. A more detailed description of the further transport device 105 is therefore not given at this point.

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 figure 4 the braking process of the transport device 5 is initiated by the overrun lever 22 of the transport device 5 striking the overrun skid 123 of the further transport device 105. The overrun skid 123 acts on the overrun lever 22 of the transport device 5 in such a way that the coupling device 25 is pivoted. By pivoting the coupling device 25, the positive connection of the driver 11 of the chain 10 with the driver element, designed as a cam 21, of the coupling device 25 is released. Thus, the overrun lever 22 causes the chain 10 and the tractor 40 to be 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 figure 4 The example shown makes it clear that forces occurring during braking or braking energy can also be advantageously absorbed by means of the pendulum device 65 , with the lifting beam 31 being raised in the direction of the arrow 94 . In the example shown, the support frame 32 and the item 30 to be transported are also raised with the lifting beam 31 . Braking energy is converted by lifting in the direction of arrow 94 . through the in figure 4 If the load beam 31 is lifted in the direction of arrow 94, the distance between the towing vehicle 40 of the transport device 5 and the carrying vehicle 41 of the preceding unit 6 is reduced. In the example shown, the rod 60 of the pendulum device 65 is moved relative to the towing vehicle 40 in the direction of 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 figure 4 is the the coupling device 25 pivoted into a second position, in which position the cam 21 is located below the path of movement of the carrier 11 arranged on the chain 10 . The coupling device 25 of the towing vehicle 40 of the transport device 5 cannot be caught 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.As an alternative and/or in addition to the run-on skids 23, 123, the transport system 80 can have one or more stoppers, which are not shown in detail in the figures, for stopping the transport device 5 when the chain 10 is running. Such stoppers can, for example, be actuated electromagnetically or electro-pneumatically and can be mounted, for example, on the chain rail 1 by means of clamp fastenings. By means of such stoppers and/or by means of the ramp skids 23, 123, transport devices 5, 105 can be stopped, stacked one after the other 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 the Figures 1 to 4 shown chain 10 can be regulated as required. Compared to the prior art, the invention enables higher transport speeds without sacrificing operational reliability. According to the invention, a comparatively more 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 during operation are improved. Due to the pendulum device 65, the provision of components such as springs, elastic buffers and/or hydraulic components can be dispensed with at least in part, with at least the same or improved functionality. Opposed to such known components is the shuttle described above 65 less prone to wear.
