Abstract

In order to provide an overhead conveyor system which ensures increased versatility of use, above all permits a high degree of variability with respect to the drives for the transport chain, and in order in particular to fulfil extremely varied technical requirements made of the system in a particular case, such as e.g. different deactivation times of the individual transport chain lengths, buffer zones or the like, a rail-bound, mobile drive means is provided as direct drive for a transport chain. Preferably, the drive means can be guided in a separate rail system, as a result of which each of the rails can be dimensioned according to the specific requirements with optimised use of materials. A drag chain of a power and free system may be provided as a direct drive for the transport chain. <IMAGE>

Description

Die Erfindung betrifft ein Hänge-Fördersystem für insbesondere länglich ausgebildete und in relativ geringen Abständen zueinander angeordnete Gegenstände wie Spulen, Flaschen od.dgl., wobei die Gegenstände von einer endlichen Transportkette aufgenommen und bewegt werden und die Transportkette mit mindestens einem Antrieb wirkverbunden ist.The invention relates to a hanging conveyor system for objects, in particular elongated and arranged at relatively short distances from one another, such as coils, bottles or the like, the objects being picked up and moved by a finite transport chain and the transport chain being operatively connected to at least one drive.

Derartige Hänge-Fördersysteme sind allgemein aus der Praxis bekannt und werden z.B. in der Textilindustrie zum Befördern, wahlweisen Stillstand einzelner Transportkettenzüge z.B. für Bearbeitungszwecke derart angeordneter Gegenstände und/oder Speichern von Spulen eingesetzt. Die als Lastaufnahmemittel ausgebildeten einzelnen Transportketten (Trolleyzüge) ermöglichen ein Befestigen der Spulen dicht nebeneinander. Durch die Verwendung einer Transportkette als Lastaufnahmemittel, insbesondere einer Kardangelenkkette, sind sowohl Steigfahrten als auch enge Kurvenfahrten möglich, so daß derartige Hänge-Fördersysteme relativ platz- und raumsparend ausgelegt sowie eingesetzt werden können und damit wirtschaftlich nutzbar sind. Nachteilig bei diesen bekannten Hänge-Fördersystemen sind die zum Verfahren der Transportkette eingesetzten Antriebe. Diese sind als stationäre Reibrad-Antriebe ausgebildet und müssen in hoher Anzahl innerhalb der Gesamtstrecke eines Hänge-Fördersystems angeordnet werden, um ein kontinuierliches Verfahren jeder Transportkette zu ermöglichen. Dabei muß gewährleistet sein, daß der Abstand zwischen den stationär angeordneten Antrieben jeweils geringer ist als die kleinste Länge einer als Trolleyzug ausgebildeten Transportkette. Zusätzlich müssen aufwendige Steuerungen vorgesehen sein, wenn man vermeiden will, daß jeder Antrieb bei hohem Energieverbrauch permanent in Betrieb ist, auch wenn gerade keine Transportkette zu transportieren ist. Durch die hohe Anzahl der einzusetzenden Antriebe und der aufwendigen Steuerungsmaßnahmen sind diese Hänge-Fördersysteme kosten- und herstellungsaufwendig. Aufgrund der hohen Anzahl der verwendeten Antriebe ist zudem die Defektanfälligkeit unbefriedigend hoch. Zu den erforderlichen Reparaturen muß die gesamte Anlage angehalten werden, wodurch die Wirtschaftlichkeit stark einschränkende Stillstandszeiten entstehen können.Suspended conveyor systems of this type are generally known from practice and are used, for example, in the textile industry for conveying, optionally stopping individual transport chain hoists, for example for processing objects arranged in this way and / or storing bobbins. The individual transport chains (trolley trains) designed as load handling devices enable the spools to be fastened close together. The use of a transport chain as a load handling device, in particular a universal joint chain, enables both climbing and tight cornering, so that such suspension conveyor systems can be designed and used in a relatively space and space-saving manner and are therefore economically usable. A disadvantage of these known overhead conveyor systems are the drives used to move the transport chain. These are designed as stationary friction wheel drives and have to be arranged in large numbers within the total distance of a suspended conveyor system in order to enable a continuous movement of each transport chain. It must be ensured that the distance between the stationary drives is less than the smallest length of a transport chain designed as a trolley train. In addition, complex controls must be provided if you want to avoid that each drive is permanently in operation with high energy consumption, even if no transport chain is currently to be transported. Due to the high The number of drives to be used and the complex control measures required, these overhead conveyor systems are expensive and expensive to manufacture. Due to the high number of drives used, the susceptibility to defects is also unsatisfactorily high. To carry out the necessary repairs, the entire system must be stopped, which can lead to extremely restrictive downtimes.

Der Erfindung liegt demgegenüber die Aufgabe zugrunde, ein Hänge-Fördersystem der eingangs genannten Art zu schaffen, das eine erhöhte Einsatzvielfalt sicherstellt, vor allem eine hohe Variabilität hinsichtlich der Antriebe für die Transportkette ermöglicht, um insbesondere den unterschiedlichsten, jeweils bei der Anlage vorliegenden technischen Erfordernissen, wie z.B. unterschiedlichen Stillstandszeiten der einzelnen Transportkettenzüge, Pufferzonen od.dgl. gerecht zu werden.The invention is based on the object to provide a overhead conveyor system of the type mentioned, which ensures increased versatility, especially a high variability with respect to the drives for the transport chain, in particular to meet the various technical requirements that are present in the system , such as Different downtimes of the individual chain hoists, buffer zones or the like. to meet.

Diese Aufgabe wird bei einem Hänge-Fördersystem der eingangs genannten Art dadurch gelöst, daß als direkter Antrieb für die Transportkette ein schienengebundenes, verfahrbares Antriebsmittel vorgesehen ist. Demzufolge ist die Transportkette direkt mit einem selbstfahrbaren Antrieb wirkverbunden, wodurch eine hohe Anzahl stationär angeordneter Antriebe und deren aufwendige Steuerung entfallen kann, während sich verschiedenste Antriebsmöglichkeiten eröffnen und Herstellungs-Aufwand und Fertigungskosten für den Antrieb der Transportkette und der zugehörigen Steuerung entsprechend den unterschiedlichsten Anforderungen jeweils optimiert werden können und die Störanfälligkeit gegenüber herkömmlicher Anlagen verringert ist.This object is achieved in a overhead conveyor system of the type mentioned in that a rail-bound, movable drive means is provided as a direct drive for the transport chain. As a result, the transport chain is directly connected to a self-propelled drive, which eliminates the need for a large number of stationary drives and their complex controls, while opening up a wide variety of drive options and manufacturing effort and manufacturing costs for the drive of the transport chain and the associated control in accordance with a wide variety of requirements can be optimized and the susceptibility to malfunction compared to conventional systems is reduced.

Vorteilhafterweise kann das Antriebsmittel in einem separaten Schienensystem geführt sein, wodurch jede der Schienen entsprechend den speziellen Anforderungen bei entsprechend optimiertem Materialeinsatz dimensioniert werden kann.The drive means can advantageously be guided in a separate rail system, as a result of which each of the rails can be dimensioned according to the special requirements with a correspondingly optimized use of material.

Besonders kostengünstig und zweckmäßig kann der Antrieb als direkter Antrieb für die Transportkette eine Schleppkette eines Power- und Free-Systems vorgesehen sein. Eine solche Kopplung der Transportkette mit einem Antrieb eines Power- und Free-Systems ergibt eine robuste, wenig störanfällige, energetisch günstig nutzbare und vom Steuerungsaufwand her relativ unaufwendige Anlage zum hängenden Fördern von Gegenständen.Particularly advantageously and expediently, the drive can be provided as a direct drive for the transport chain, a drag chain of a power and free system. Such a coupling of the transport chain with a drive of a power and free system results in a robust, less prone to failure, energy-efficient usable and relatively inexpensive control system for hanging objects.

Andererseits kann ein ebenfalls recht vielseitig einsetzbarer Antrieb zur Verfügung gestellt werden, wenn man als direkten Antrieb für eine Transportkette eine Elektrohängebahn vorsieht, die die Transportkette nach Art einer Lokomotive verfährt. Durch eine solche Konfiguration ist es z.B. möglich, als Antrieb für ein Hänge-Fördersystem nur eine einzige, zumindest aber eine nur geringe Anzahl Elektrohängebahn-Antriebswagen für eine Mehrzahl von Transportketten zu verwenden.On the other hand, a drive that is also very versatile can be provided if an electric monorail system is provided as a direct drive for a transport chain, which drives the transport chain like a locomotive. With such a configuration it is e.g. possible to use only a single, or at least only a small number of electric monorail drive carriages for a plurality of transport chains as the drive for a overhead conveyor system.

Ein Hänge-Fördersystem ist besonders wirtschaftlich herstellbar, wenn das Schienensystem der Elektrohängebahn hinsichtlich Profil und/oder Kontur bzw. Verlauf abweichend vom Schienensystem der Transportkette ausgebildet ist. Somit können die Schienensysteme für die Transportkette und für das Antriebsmittel unterschiedliche Verläufe aufweisen, so daß z.B. das Schienensystem für das Antriebsmittel einfach und unkompliziert ohne Verwendung von Weichen oder ähnlichen Einrichtungen als Rundkurs ausgebildet sein kann, wogegen das Schienensystem für die Transportkette, das bestimmten technologischen Abläufen gerecht werden muß, mit Pufferzonen, Steigfahrtbereichen o.ä. versehen sein kann, die an einer parallel zum Schienensystem für die Elektrohängebahn verlaufenden Grundschiene für die Transportkette über Stellmittel wie Weichen od.dgl angeordnet sind. Die Elektrohängebahn wird je nach Anforderung mit einer der Transportketten verbunden und transportiert sie, wie bereits gesagt, nach Art einer Lokomotive zu einer Bearbeitungsstation, einem Speicher- oder Pufferungsplatz oder ähnlichem.A overhead conveyor system can be produced particularly economically if the rail system of the electric monorail system is designed differently from the rail system of the transport chain with regard to profile and / or contour or course. Thus, the rail systems for the transport chain and for the drive means can have different courses, so that, for example, the rail system for the drive means can be simply and easily designed as a round trip without the use of switches or similar devices, whereas the rail system for the transport chain, the certain technological processes must be met, with buffer zones, climbing areas or similar. can be provided, which are arranged on a parallel to the rail system for the electric monorail base rail for the transport chain via adjusting means such as switches or the like. The monorail conveyor is connected to one of the transport chains depending on the requirements and, as already mentioned, transports them like a locomotive to a processing station, a storage or buffering station or the like.

Dazu kann der Elektrohängebahn eine Kupplung z.B. in Form einer Kupplungskette zur Verbindung mit mindestens einer Transportkette zugeordnet sein. Eine solche Kupplungskette kann vorteilhaft und den praktischen Anforderungen entsprechend bereitgestellt werden, indem sie als Gelenkkette, insbesondere Kardangelenkkette ausgebildet ist.For this purpose, the monorail conveyor can use a coupling e.g. in the form of a coupling chain for connection to at least one transport chain. Such a coupling chain can be provided advantageously and in accordance with practical requirements by being designed as an articulated chain, in particular a universal joint chain.

Vorteilhafterweise kann die Kupplungskette mindestens ein Kopplungselement zum Verbinden mit der Elektrohängebahn und/oder der Transportkette umfassen. So läßt sich eine einfache und schnelle Trennung von Kupplungskette und Transportkette erreichen, wenn diese in den vorgesehenen Abschnitt transportiert werden und anschließend, nach Entkuppeln, eine andere Transportkette über die mit der Kupplungskette verbundene Elektrohängebahn verfahren werden soll.The coupling chain can advantageously comprise at least one coupling element for connection to the electric monorail conveyor and / or the transport chain. In this way, a simple and quick separation of the coupling chain and the transport chain can be achieved if these are transported in the intended section and then, after uncoupling, another transport chain is to be moved via the electric overhead conveyor connected to the coupling chain.

Ein in Fig. 1 dargestelltes Hänge-Fördersystem 1 umfaßt eine Schiene 6 zur Aufnahme eines Antriebsmittels 5 in Form einer Schleppkette 8 eines Power- und Free-Systems und eine im wesentlichen parallel zu dieser Schiene 6 verlaufende Schiene 7 für eine Transportkette 2, an der zu befördernde Gegenstände 3 in allgemein üblicher und bekannter Art und Weise befestigt sind. Beide Schienen 6, 7 sind über Flanschbleche 13 miteinander verbunden und zusammen an einer Hallendecke oder ähnlichem befestigt. Durch die Anhängung der Gegenstände 3 an einer als Gelenkkette, speziell Kardangelenkkette ausgebildeten Transportkette 2 können die Abstände zwischen den Gegenständen 3 auf einem notwendigen Minimum gehalten werden, wodurch eine wirtschaftliche Förderung einer großen Anzahl von Gegenständen bei geringem Raum- bwz. Platzbedarf und vor allem auch das Durchfahren enger Kurven sowie von Steigungen möglich ist, was gleichzeitig bisher nicht bei den nicht-stationären Antriebssystemen erzielbar war. Die Transportkette 2 umfaßt mindestens einen Power- und Free-Wagen 16, der je nach Erfordernis der Verbindung mit einem Mitnehmer 12 der Schleppkette 8 dient. Durch die Kombination einer Transportkette 2 mit einer Schleppkette 8 eines Power- und Free-Systems sind bei Einsparung von Antrieben und Steuerung gleiche dreidimensionale Streckenführungen erreichbar, wie dies nur bei den bisher bekannten, über eine große Anzahl stationärer Reibrad-Antriebe verfahrener Trolleysysteme möglich war. Bei den bisher üblichen Power- und Free-Systemen wurde die Schleppkette 8 mit sperrigen Traversen zur Aufnahme der Gegenstände verbunden, so daß deren dicht beieinanderliegende Anordnung nur beschränkt möglich war. Die Traversen verhindern demzufolge eine enge Kurven aufweisende Streckenführung, wodurch für solche Systeme ein hoher Platzbedarf erforderlich ist.A suspension conveyor system 1 shown in Fig. 1 comprises a rail 6 for receiving a drive means 5 in the form of a drag chain 8 of a power and free system and a rail 7 running essentially parallel to this rail 6 for a transport chain 2, on the Objects 3 to be transported are fastened in a generally customary and known manner. Both rails 6, 7 are connected to one another via flange plates 13 and fastened together on a hall ceiling or the like. By attaching the objects 3 to a transport chain 2 designed as an articulated chain, specifically a universal joint chain, the distances between the objects 3 can be kept to a necessary minimum, thereby economically promoting a large number of objects in a small space. Space requirements and above all driving through tight bends and inclines is possible, which at the same time was not previously possible with the non-stationary drive systems. The transport chain 2 comprises at least one power and free carriage 16, which, depending on the requirements, serves to connect to a driver 12 of the drag chain 8. By combining a transport chain 2 with a drag chain 8 of a power and free system, the same three-dimensional route guidance can be achieved while saving on drives and control, as was only possible with the previously known trolley systems, which had been moved over a large number of stationary friction wheel drives. In the previously common power and free systems, the drag chain 8 was connected to bulky traverses for receiving the objects, so that their close arrangement was only possible to a limited extent. The crossbeams therefore prevent narrow routing, which means that such systems require a lot of space.

Durch die erfindungsgemäße Zuordnung einer Transportkette 2 zu einer schienengebundenen, verfahrbaren, als Antriebsmittel 5 ausgebildeten Schleppkette 8 eines Power- und Free-Systems sind neben einer geringe Kurvenradien aufweisenden Streckenführung für den Transport auch platzsparende Zwischenlagerungen für die an der Transportkette 2 aufgenommenen Gegenstände. 3 erreichbar. Eine solche Pufferung der Gegenstände 3 kann hinsichtlich Prozeßführung sowie Raumausnutzung bedeutende wirtschaftliche Effekte erreichen. In den Fig. 2 und 3 sind mögliche Streckenführungen einer Zwischen- bzw. Pufferlagerung dargestellt, wobei Fig. 2 eine wendelförmige Speicherstrecke und Fig. 3 eine schneckenartig ausgebildete Speicherstrecke zeigen.The inventive assignment of a transport chain 2 to a rail-bound, movable drag chain 8, designed as drive means 5, of a power and free system, in addition to a route with small radii of curvature, also saves space-saving intermediate storage for the objects accommodated on the transport chain 2. 3 reachable. Such a buffering of objects 3 can achieve significant economic effects in terms of process control and space utilization. FIGS. 2 and 3 show possible routes of an intermediate or buffer storage, FIG. 2 showing a helical storage section and FIG. 3 a helical storage section.

Durch die in Fig. 4 dargestellte Kopplung einer Gegenstände 3 aufnehmenden Transportkette 2 mit einer Elektrohängebahn 9 als Antriebsmittel 5 ist ebenfalls eine wirtschaftliche Förderung von relativ eng zueinander beabstandeten Gegenständen erreichbar. Eine weitere und bedeutende Erhöhung des Einsatzbereiches ist dadurch erreichbar, daß der Elektrohängebahn 9 eine Kupplungskette 10 in Form einer Gelenkkette 11 zugeordnet ist, die die Verbindung zur Transportkette 2 über entsprechende Kopplungselemente 15 herstellt. Die Kupplungskette 10 kann in ihrer Länge je nach Erfordernis variiert werden. Durch den Einsatz einer Kupplungskette 10 können das Schienensystem für die Elektrohängebahn 9 und das Schienensystem für die Kupplungskette 10 und die Transportketten 2 hinsichtlich ihres Verlaufes, d.h. hinsichtlich ihres Profiles und ihrer Kontur, unterschiedlich gestaltet werden, indem einer parallel zum Schienensystem 6 für die Elektrohängebahn 9 verlaufenden Grundschiene für die Kupplungskette 10 und die Transportketten 2 Abzweigungsschienen 17 in Form von Steigfahrten, Pufferzonen od.dgl. über entsprechende Stellmittel zugeordnet sind. Damit kann z.B. das Schienensystem 6 für die Elektrohängebahn 9 als einfacher kostengünstiger Rundkurs ohne Weichen oder andere Stellelemente ausgebildet sein. Das Schienensystem 7 für die Kupplungskette 10 und die Transportketten 2 kann äußerst variabel gestaltet werden, da die Elektrohängebahn 9 über die Kupplungskette 10 die Transportkette 2 je nach Bedarf und Notwendigkeit innerhalb des Schienensystems 7 nach Art einer Lokomotive funktioniert.The coupling of a transport chain 2 accommodating objects 3 to an electric monorail 9 as a drive means 5, as shown in FIG reachable. A further and significant increase in the range of use can be achieved in that the electric monorail 9 is assigned a coupling chain 10 in the form of an articulated chain 11 which establishes the connection to the transport chain 2 via corresponding coupling elements 15. The length of the coupling chain 10 can be varied as required. By using a coupling chain 10, the rail system for the electric monorail 9 and the rail system for the coupling chain 10 and the transport chains 2 can be designed differently with regard to their course, ie with regard to their profile and their contour, by one parallel to the rail system 6 for the electric monorail 9 extending base rail for the coupling chain 10 and the transport chains 2 branch rails 17 in the form of climbing trips, buffer zones or the like. are assigned via appropriate actuating means. Thus, for example, the rail system 6 for the electric monorail 9 can be designed as a simple, inexpensive circuit without switches or other actuating elements. The rail system 7 for the coupling chain 10 and the transport chains 2 can be designed to be extremely variable, since the electric monorail 9 via the coupling chain 10, the transport chain 2 functions as required within the rail system 7 in the manner of a locomotive.

So ist es z.B. möglich, wie dies aus den Figuren 5 und 6 hervorgeht, eine Transportkette 2 bestimmter Länge mit der auf dem als Rundkurs ausgebildeten Schienensystem 6 für den Antrieb 4 zu einer außerhalb dieses Rundkurses liegenden Bearbeitungsstation 14 oder zu einer Pufferschiene zu verfahren, indem durch die von der Elektrohängebahn 9 angetriebene Gelenkkette 11 die Transportkette 2 in die gewünschte Position verschoben bzw. gezogen wird. Durch die Verbindung der Elektrohängebahn 9 mit der Kupplungskette 10 können weiterhin problemlos Steigungen und enge Kurven durchfahren werden.For example, as can be seen from FIGS. 5 and 6, it is possible to move a transport chain 2 of a certain length with the drive system 4 on the rail system 6 designed as a circular route to a processing station 14 lying outside this circular route or to a buffer rail by the conveyor chain 2 is moved or pulled into the desired position by the articulated chain 11 driven by the electric monorail conveyor 9. By connecting the electric monorail 9 to the coupling chain 10, gradients and tight curves can still be negotiated without any problems.
