Abstract

The cable coupling clamp is to be used in cableways for transporting workpieces in a production plant with suspension gear (2) which can be coupled to a circulating conveying cable (4), receives the workpieces and is supported by rails (1). The cable clamp (5) has two clamping jaws (11, 12) which grasp the conveying cable (4), one clamping jaw (11) being secured to a clamping frame (6) and the other clamping jaw (12) being capable of being pressed onto the conveying cable (4) by means of spring force and lifted off from it by means of a lever (16) which is pivotably mounted on the clamping frame (6) and can be controlled by a fixed connecting member. The clamp frame (6) is coupled to the suspension gear (2) by means of a pivotably mounted link (7). When the cable clamp (5) is secured to the conveying cable (4), the link (7) or the straight element (10) which connects its two pivot axes (8, 9) is approximately vertical. The pivot axes (8, 9) of the link (7) lie parallel to the axis of the clamping mouth, formed by the two clamping jaws (11, 12), of the cable clamp (5). When the clamping mouth is open and the clamp (5) has been pivoted down laterally from the carrying cable (4) by means of the link (7), the clamping mouth lies at the side of and below the conveying cable (4). <IMAGE>

Description

Die Erfindung bezieht sich auf eine kuppelbare Seilklemme für Seilförderanlagen, zum Transport von Werkstücken in einer Fertigungsanlage mit an ein umlaufendes Förderseil ankuppelbare, die Werkstücke aufnehmendes und von Schienen getragenes Gehänge mit den Merkmalen des Oberbegriffes des Patentanspruches 1.The invention relates to a detachable cable clamp for cable conveyor systems, for transporting workpieces in a manufacturing system to a rotating one Conveyor rope that can be coupled, that receives the workpieces and that is carried by rails Hangers with the features of the preamble of claim 1.

Aus der DE-OS 22 44 979 ist eine Seilförderanlage für industrielle Zwecke beschrieben mit einem umlaufenden Seil, das zwei Funktionen zu erfüllen hat, nämlich die Funktion eines Tragseiles und die Funktion eines Zugseiles. Andererseits sind im Seilbahnbau Anlagen mit getrennten Zug- und Tragseilen bekannt. Mit der aus der DE-OS 22 44 979 bekannten Einrichtung können keine schweren Lasten transportiert werden. Eine seilbahnähnliche Konstruktion mit Tragseil und Förderseil für schwere Lasten ist in industriellen Fertigungsanlagen nicht brauchbar, da die Positionierung der einzelnen Werkstücke oder Gehänge innerhalb der Werk- oder Montagehalle relativ zu einer Werkzeugmaschine oder einem Werkzeugroboter durch das Tragseil nicht ausreichend genau eingehalten werden kann, abgesehen davon, daß hier noch zusätzlich die Schwingungsfähigkeit des Tragseiles berücksichtigt werden müßte. Es werden daher, um diesem Nachteil zu begegnen, die lastaufnehmenden Gehänge auf ortsfest verlaufenden Lauf- oder Tragschienen abgestützt, und zwar in der Weise, daß das gesamte Gewicht sowohl des Gehänges wie auch des Werkstückes von der Lauf- und Tragschiene übernommen wird. Für den Transport des Gehänges und des Werkstückes dient nun aber ein umlaufendes Förderseil, wobei Maßnahmen vorgesehen sein müssen, um das Gehänge bzw. das von ihm getragene Werkstück von diesem Förderseil ab- bzw. an dieses anzukuppeln. Dadurch kann beispielsweise innerhalb der Fertigungszone ein Pufferbereich dargestellt werden, der seinerseits mit einem Kettentransfer ausgestattet werden kann. Es können hier auch Höhen- und Gefällstrecken überwunden werden, ohne daß Hubeinrichtungen bzw. eigene Hubstationen eingesetzt werden müssen. Das Ankuppeln bzw. Abkuppeln des Gehänges an das Förderseil geschieht über eine kuppelbare oder schaltbare Seilklemme, die neben zumindest einem Laufrad, über das sich das Gehänge auf der Tragschiene abstützt, am Gehänge selbst befestigt ist. Das Förderseil wird zweckmäßigerweise oberhalb sowie seitlich versetzt zur Tragschiene geführt, um die Seilklemmme im wesentlichen mittig über dem Laufrad anordnen zu können, um die Kräfte zweckmäßig in die Konstruktion einzuleiten. Zur Führung des Förderseiles dienen Seilstützräder und/oder Umlenkräder, die an Stützen oder Bügeln befestigt werden, die wiederum an den Laufschienen festgelegt sind. Das Förderseil dient dabei als Antriebselement für eine Einschienenhängebahn mit den als Einzelfahrzeuge ausgebildeten Gehängen.

From DE-OS 22 44 979 a cable conveyor system for industrial purposes is described with a rotating cable that has two functions to perform, namely the function of a suspension cable and the function of a traction cable. On the other hand, systems with separate traction and suspension cables are known in cable car construction. With the device known from DE-OS 22 44 979 no heavy loads can be transported. A cable car-like construction with a carrying cable and conveyor cable for heavy loads cannot be used in industrial production plants, since the positioning of the individual workpieces or hangers within the factory or assembly hall relative to a machine tool or a tool robot cannot be maintained with sufficient accuracy by the carrying cable, apart from that that here the vibration ability of the suspension cable would have to be taken into account. In order to counter this disadvantage, the load-bearing hangers are supported on stationary running or support rails, in such a way that the entire weight of both the hangers and the workpiece is borne by the running and support rails. For the transport of the hanger and the workpiece, however, a revolving conveyor rope is used, whereby measures must be provided to uncouple the hanger or the workpiece carried by it from this conveyor rope or to couple it to it. In this way, for example, a buffer area can be displayed within the production zone, which in turn can be equipped with a chain transfer. It is also possible to negotiate uphill and downhill sections without having to use lifting devices or separate lifting stations. The hanger is coupled or uncoupled to the conveyor cable via a detachable or switchable rope clamp, which is attached to the hanger itself in addition to at least one impeller via which the hanger is supported on the mounting rail. The conveyor cable is expediently guided above and laterally offset to the mounting rail in order to be able to arrange the cable clamps essentially centrally over the impeller in order to appropriately introduce the forces into the construction. Rope support wheels and / or deflection wheels, which are fastened to supports or brackets, which are in turn fixed on the running rails, are used to guide the conveyor cable. The conveyor cable serves as a drive element for a monorail monorail with the hangers designed as individual vehicles.

Kuppelbare bzw. schaltbare Seilklemmen sind in großer Zahl bekannt (AT-PS 164 890; 276 477; 349 058; 370 686; 375 047; 382 127; 388 346; EU-PS 150 701; 174 701; CH-PS 509 900; US-PS 4441 430; 3662 691; 3416 462). Sie sind, unabhängig von ihrer jeweiligen konstruktiven Gestaltung direkt am Gehänge festgelegt. Beispielsweise ist in der AT-PS 164 890 eine Seilkuppelvorrichtung gezeigt und beschrieben, die für Seilschwebebahnen entwickelt wurde, die nur ein Seil besitzen, das gleichzeitig als Zugseil und als Tragseil dient. Dieses Seil läuft dauernd um, wogegen das Gehänge mittels der Seilkuppelvorrichtung längs einer besonderen Kuppelstation mit dem Seil gekuppelt bzw. vom Seil gelöst werden kann. Diese Seilklemmvorrichtung besitzt einen von vier Rädern getragenen Wagen, an welchem über einen ortsfesten Lagerbolzen das Gehänge angelenkt ist. Das Trag- und Zugseil befindet sich stets, unabhängig davon, ob die Klemmvorrichtung aktiviert oder gelöst ist, zwischen den Räderpaaren des Wagens. Das Gehänge ist unmittelbar über dem Lagerbolzen an diesem Wagen angelenkt und von ihm getragen. Zwischen dem Wagen und dem Gehänge ist ein mit der Achse der einen Klemme verschwenkbarer Hebel verbunden, mit welchem über ein Langloch und einen Bolzen das Gehänge in Wirkverbindung steht, das beim Schließen bzw. beim Öffnen der Klemme um den am Wagen ortsfesten Lagerbolzen geschwenkt wird zur Verlagerung des Schwerpunktes. Auf freier Strecke, also außerhalb der Kuppelstationen, übernimmt das Seil sowohl die gesamte Last des Gehänges wie auch dessen Transport.Couplable or switchable rope clamps are known in large numbers (AT-PS 164 890; 276 477; 349 058; 370 686; 375 047; 382 127; 388 346; EU-PS 150 701; 174 701; CH-PS 509 900; U.S. Patent 4,441,430; 3662 691; 3416 462). You are independent determined by their respective constructive design directly on the hanger. For example, a rope coupling device is shown in AT-PS 164 890 and described that was developed for cable cars that only use a rope own, which also serves as a pulling rope and as a carrying rope. This rope runs continuously um, whereas the hanger by means of the rope coupling device along a special Coupling station can be coupled with the rope or detached from the rope can. This rope clamping device has a carriage carried by four wheels, on which the hanger is articulated via a fixed bearing pin. The carrying and pull rope is always there, regardless of whether the clamping device is activated or released, between the wheels of the car. The hanger is articulated directly above the bearing pin on this car and by worn to him. Between the carriage and the hanger is one with the axis of the a clamp pivoted lever connected to which via an elongated hole and a bolt is operatively connected to the hanger that when closing or when opening the clamp pivoted around the fixed bearing bolt on the carriage becomes a shift in focus. On the free route, i.e. outside of the coupling stations, the rope takes on both the entire load of the Hangers as well as their transportation.

Solche bekannte Seilklemmen können nun für Anlagen der eingangs geschilderten Art nicht verwendet werden, da keine Möglichkeit und auch keine Notwendigkeit besteht, mit der vom Förderseil gelösten, offenen Klemme unterhalb des Förderseiles durchzufahren, was bei Seilförderanlagen der eingangs geschilderten Art jedoch notwendig ist, bei welchen beispielsweise die ortsfest verlaufende Tragschiene für das Gehänge mit Weichen bestückt ist. Auch müssen horizontale Seilrollen oder Seilstützräder, wie sie bevorzugt im Antriebsbereich vorgesehen sind, passiert werden können.Such known rope clamps can now be used for systems of the type described above Kind not be used as there is no possibility and no need either exists, with the open clamp underneath the conveyor cable detached from the conveyor cable to go through what with rope conveying systems of the type described is necessary, however, in which, for example, the stationary mounting rail for the hanger is equipped with switches. Also need horizontal pulleys or rope support wheels, as are preferably provided in the drive area, can happen.

Ausgehend von diesem Stand der Technik schlägt die Erfindung zur Lösung der geschilderten Aufgabe jene Maßnahme vor, die Inhalt und Gegenstand des kennzeichnenden Teiles des Patentanspruches 1 ist. Die erfindungsgemäße Seilklemme ist nicht für Seilschwebebahnen vorgesehen und für solche auch nicht verwendbar, sondern für Seilforderanlagen für industrielle Zwecke. Eine solche industrielle Seilförderanlage besteht aus einem ortsfest angeordneten Schienensystem, das in der Regel in sich geschlossen ausgebildet ist. Auf diesem ortsfesten Schienensystem laufen Fahrzeuge. Mit diesen Fahrzeugen oder Wagen sind Gehänge verbunden, die gewichtige Werkstücke tragen, die innerhalb dieser Anlage unterschiedlichen Montage- und/oder Fertigungsstationen zuzustellen sind. Um diese Fahrzeuge entlang diesem Schienensystem zu bewegen, dient ein umlaufendes Transportseil. Die genannten Fahrzeuge mit der angehängten Last werden zum Transport von einer Montage- oder Fertigungsstelle zur anderen an das umlaufende Seil angeklemmt. Auf eine solche Seilklemme in einer solchen Anlage bezieht sich die Erfindung. Das erwähnte ortsfeste Schienensystem besitzt auch Weichen und Abzweigungen. Das der Erfindung zugrunde liegende Problem liegt nun darin, daß Maßnahmen vorzusehen sind, daß der auf dem Schienensystem verfahrbare Wagen mit dem Gehänge bei gelöster, also offener Klemme das oberhalb der Schiene verlaufende Förderseil passieren kann und daß auch die Seilrollen passiert werden können, die entlang des Schienensystems zur Führung des Förderseiles notwendig sind.Based on this prior art, the invention proposes to solve the outlined task that measure, the content and subject of the characteristic Part of claim 1 is. The rope clamp according to the invention is not intended for aerial cableways and cannot be used for such, but for rope handling systems for industrial purposes. Such an industrial Rope conveyor system consists of a fixedly arranged rail system, which in is generally designed to be self-contained. On this fixed rail system run vehicles. Hangers are connected to these vehicles or wagons, which carry weighty workpieces that differ within this system Assembly and / or manufacturing stations are to be delivered. To these vehicles A circumferential transport rope serves to move along this rail system. The vehicles mentioned with the attached load are used for transport from one assembly or manufacturing site to the other on the circulating rope clamped. To such a cable clamp in such a system refers to the Invention. The above-mentioned fixed rail system also has switches and branches. The problem underlying the invention is now that Measures must be taken to ensure that the wagon can be moved on the rail system with the hanger when the clamp is loosened, i.e. open, above the rail running conveyor rope can pass and that the rope pulleys are also passed may be necessary along the rail system to guide the hoisting rope are.

Die Innenseite des Querholmes 20 besitzt eine zylindrische Wölbung 31, deren Krümmung jener der Druckrolle 29 entspricht, so daß Druckrolle 29 und die erwähnte Wölbung 31 rastend ineinandergreifen, wenn die Klemme geschlossen ist (Fig. 4).The movable jaw 12 is connected to a shaft 21, one of two Sleeve parts 22 and 23 existing sleeve is added. On their opposite Sides have these sleeve parts 22 and 23 each have a collar 24 and 25, on which one of disc springs existing spring assembly 26 is present. The facing end faces of the sleeve parts 22 and 23 are equipped with interlocking claws. From Fig. 3 it can be seen that the Sleeve parts are axially displaceable against each other. The bottom of the sleeve part 23 is pierced and through the hole provided here a connecting screw protrudes into the Shank 21 is screwed in and fixed here. The sleeve part 23 carries on its the jaws 12 facing away from a fork 27 which is penetrated transversely by a shaft 28. In the gap the fork 27 and on the shaft 28, a pressure roller 29 is rotatably mounted. The shaft 28 is so long that its shaft ends engage in slot holes 30 which are in the frame sides 17 ' are recessed and beyond this frame side 17 protrude somewhat to the outside. The Inside of the cross member 20 has a cylindrical curvature 31, the curvature of which the Pressure roller 29 corresponds, so that pressure roller 29 and the aforementioned curvature 31 engage in one another, when the clamp is closed (Fig. 4).

    Zwei hakenartige Höcker 32 sind an den Schenkeln 33 des U-förmigen Hebels 16 festgelegt und liegen im Bereich der Langlochausnehmungen 30 der Rahmenseiten 17, gegenüber welchen die Enden der Welle 28 etwas vorstehen (Fig. 2).Two hook-like bumps 32 are fixed to the legs 33 of the U-shaped lever 16 and lie in the region of the elongated hole recesses 30 of the frame sides 17, against which the Projecting ends of the shaft 28 slightly (Fig. 2).

    Die Funktionsweise der Seilklemme ergibt sich aus deren konstruktivem Aufbau. Bei geschlossener, das Förderseil fassender Klemme (Fig. 4) werden über das Federpaket 26 die Klemmbacken 11 und 12 gegeneinander gepreßt. Der Querhorn 20 des Hebels 16 befindet sich in seiner Raststellung, in der die Wölbung 31 an der Druckrolle 29 anliegt. Das sich bewegende Förderseil nimmt nun über diese geschlossene Klemme das an der Tragschiene 1 abgestützte Gehänge mit. Läuft das Gehänge 2 und damit die Seilklemme in eine Schaltstation ein, so wird vorerst die Seilklemme in ihrer aus Fig. 4 ersichtlichen Lage dadurch gehalten, daß die Führungsrollen 13 und 14 an Führungsschienen entlanglaufen. Gleichzeitig fährt der kugelartige Wälzkörper 15 in eine räumlich gekrümmte Führungskulisse ein, die nun den Hebel 16 nach unten zieht (Fig. 5), wodurch die Druckrolle 29 ihr Widerlager verliert, und unter der Wirkung der vorgespannten Feder weicht nun die Druckrolle 29 nach rechts (Fig. 5) aus, wobei die Klemme geöffnet wird. Die hakenartigen Höcker 32, die sich mit dem schwenkbaren Hebel 16 nach unten bewegen, unterstützen diese Verschiebebewegung, da sie sich nun an den gegenüber den Rahmenseiten 17 vorstehenden Enden der Welle 28 abstützen und darüberhinaus begrenzen sie die Schwenkbewegung des Hebels 16 gegenüber dem Klemmenrahmen 6 (Fig. 5). Die Klemme ist nun offen, und in der Folge wird nun durch die erwähnte, hier nicht dargestellte Führungskulisse und den von ihr formschlüssig gefaßten Wälzkörper 15 die Klemme als Ganzes um die Achse 8 verschwenkt, wobei sie vorerst etwas angehoben wird, so daß der Klemmbacken 11 über das Förderseil 4 hinweggehoben wird (Fig. 1). Die untere Endlage der so verschwenkten Seilklemme gegenüber dem Gehänge 2 ist in Fig. 1 durch die Position III veranschaulicht. Soll das Gehänge wiederum an das Förderseil 4 angekuppelt werden, so laufen die geschilderten Bewegungen in umgekehrter Reihenfolge ab. The function of the rope clamp results from its construction. When closed, the conveyor cable gripping clamp (Fig. 4) on the spring assembly 26, the jaws 11 and 12 pressed against each other. The transverse horn 20 of the lever 16 is in his Detent position in which the curvature 31 bears against the pressure roller 29. The moving conveyor rope takes the hanger supported on the mounting rail 1 via this closed clamp With. If the hanger 2 and thus the rope clamp runs into a switching station, the Cable clamp held in its position shown in FIG. 4 by the fact that the guide rollers 13th and 14 run along guide rails. At the same time, the spherical rolling element 15 moves in a spatially curved guide link, which now pulls the lever 16 downward (FIG. 5), whereby the pressure roller 29 loses its abutment, and under the action of the preloaded The spring now deflects the pressure roller 29 to the right (FIG. 5), the clamp being opened. The hook-like humps 32, which move downward with the pivotable lever 16, support this shifting movement, since they are now on the opposite of the frame sides 17th support projecting ends of the shaft 28 and furthermore they limit the pivoting movement of the lever 16 opposite the terminal frame 6 (Fig. 5). The clamp is now open and as a result of the above-mentioned management backdrop, not shown here, and the by its form-fitting rolling elements 15, the clamp as a whole is pivoted about the axis 8, initially being slightly raised, so that the clamping jaws 11 are moved over the conveyor cable 4 is lifted away (Fig. 1). The lower end position of the pivoted rope clamp compared to the hanger 2 is illustrated in Fig. 1 by the position III. Should the hanger are in turn coupled to the conveyor cable 4, the movements described run in reverse order.
