Description
Die Erfindung betrifft eine Hubvorrichtung für eine industrielle Bearbeitungsstation gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a lifting device for an industrial processing station according to the preamble of patent claim 1.
Die verfügbare Technologie im Bereich der Hebetechnik ist breit gefächert und bietet je nach Applikationsfall unterschiedlichste Realisierungsmodelle. Speziell die hohen Anforderungen an die Zuverlässigkeit einer Hubvorrichtung in rauen Fertigungsumgebungen, wie sie beispielsweise in Schweißstationen einer automobilen Fertigungslinie vorzufinden sind, verlangen vorzugsweise einfache und robuste Systemlösungen. Dies betrifft insbesondere Hubtische, die in der Serienfertigung von Kraftfahrzeugen zur vertikalen Förderung von Rohkarossen an Bearbeitungsstationen eingesetzt werden.The available technology in the field of lifting technology is broad and offers a wide variety of implementation models depending on the application. In particular, the high demands on the reliability of a lifting device in harsh manufacturing environments, such as those found in welding stations of an automotive production line, preferably require simple and robust system solutions. This concerns in particular lifting tables, which are used in the mass production of motor vehicles for the vertical conveyance of body shells at processing stations.
Zum Stand der Technik gehören Hubvorrichtungen, die eine oder mehrere gleichschenklige Geradschubkurbeln zur Führung eines vertikalbeweglichen Lastaufnahmekörpers aufweisen, wobei sich deren Gestaltung und Verwendung voneinander unterscheiden.The prior art includes lifting devices which have one or more isosceles straight-draw cranks for guiding a vertically movable load-bearing body, the design and use of which differ from one another.
Die
In der
Dabei ist jedoch von Fall zu Fall abzuwägen, in welcher Relation sich das Gewicht des Lastaufnahmekörpers zu dem Gewicht des Transportguts verhält, in welchem Maß die Getriebegröße durch die Druckfederelemente beeinflusst wird und ob sich der zusätzlich aufzubringende Fertigungsaufwand in die Herstellung von zwei Druckfederelementen und deren Anbindungsstellen wirtschaftlich rentieren kann. Diese Bauart verlangt zwei fertigungsaufwendige Getriebe mit hohen Übersetzungsverhältnissen, die ein entsprechend hohes Drehmoment aufbringen müssen, um den Lastaufnahmekörper mit Transportgut über die gleichschenkligen Geradschubkurbel vertikal zu verfahren.However, it is to be weighed case by case, in which relation the weight of the load-carrying body to the weight of the transported goods behaves, to what extent the transmission size is influenced by the compression spring elements and whether the additionally applied manufacturing effort in the production of two compression spring elements and their attachment points can economically yield. This design requires two production-consuming transmission with high gear ratios, which must apply a correspondingly high torque to move the load-carrying body with cargo over the isosceles Geradschubkurbel vertically.
Es wird in der
Bei der Verwendung von nur einer Schwinge ist das vertikale Führungssystem des Festlagers sehr biege- und verwindungssteif zu gestalten, da allein dieses das Kippen des Lastaufnahmekörpers um den Gelenkpunkt der Schwingenführung verhindern und so den Lastaufnahmekörper mit Transportgut horizontal in Waage halten muss. Beim stationsweisen Überfördern des Transportguts, wie es in automobilen Fertigungslinien der Fall ist, entstände durch die ungleiche Lastverteilung ein hohes Kippmoment um den Gelenkpunkt der Schwingenführung, was leicht zu einem nicht gewünschten Absacken der Enden des Lastaufnahmekörpers führen kann. Das Hinzufügen einer zweiten oder gar dritten mit dem Antriebsstrang verbundenen Schwinge und/oder eines zusätzlichen vertikalen Führungssystems erhöht zwar die Kippstabilität dieses Systems in hohem Maße, jedoch auch den Fertigungsaufwand wesentlich.When using only one rocker, the vertical guide system of the fixed bearing is very resistant to bending and warping, since this alone is the tilting of the load-carrying body To prevent the hinge point of the swing arm guide and so must hold the load-carrying body with cargo horizontally in balance. When stationwise Überfördern the cargo, as is the case in automotive production lines, created by the uneven load distribution a high tilting moment about the hinge point of the swing arm guide, which can easily lead to unwanted sagging of the ends of the load receiving body. The addition of a second or even third connected to the drive train rocker and / or an additional vertical guide system increases the tipping stability of this system to a great extent, but also the production cost significantly.

Es ist somit eine Aufgabe der vorliegenden Erfindung, eine Hubvorrichtung vorzuschlagen, welche geringe Bauhöhen ermöglicht und vor allem durch ihre Einfachheit ökonomische Attraktivität bietet.It is thus an object of the present invention to provide a lifting device which allows low heights and above all offers economic attractiveness by their simplicity.
Die Aufgabe wird durch die Merkmale des Patentanspruchs 1 gelöst.The object is solved by the features of patent claim 1.
Dabei wird eine Hubvorrichtung für eine industrielle Bearbeitungsstation, insbesondere ein Hubtisch für die Förderung einer Rohkarosse in der Kraftfahrzeug-Serienfertigung, vorgeschlagen, wobei die Hubvorrichtung zur Förderung eines Werkstücks auf einem in rein vertikaler Richtung bewegten Oberrahmen ausgestaltet ist. Dabei weist die Hubvorrichtung eine mit einem motorischen Antriebselement betätigte gleichschenklige Geradschubkurbel als erste Vertikalführung auf. Dabei ist die aus einer Festlagerschwinge mit deren Schwingenlager, einem Lenker mit dessen Lenkerführung, einem Lenkermittengelenk und einem mit dem Oberrahmen verbunden Festlagergelenk bestehende gleichschenklige Geradschubkurbel in der Art ausgebildet, dass diese durch das Betätigen der an der Festlagerschwinge angreifenden Zugstange bewegt wird. Insbesondere durch den Einsatz einer gleichschenkligen Geradschubkurbel, die in der Literatur auch als "Scott-Russel-Mechanismus" bekannt ist, ist eine einfache und effektive Variante eines vertikalen Führungssystems gegeben, welche geringe Bauhöhen bei minimalem Fertigungsaufwand ermöglicht. Wegen der geringen Anzahl der am vertikalen Hub beteiligten Hubelemente, als auch wegen der möglichen einfachen fertigungstechnischen Gestaltung dieser Hubelemente kann im Vergleich zum Stand der Technik die Systemkomplexität minimiert und damit signifikanten Vorteile erzielt werden. Dazu gehören eine flache, kompakte und robuste Bauweise, eine einfache und kostengünstige Fertigung, eine hohe Anlagenverfügbarkeit, geringer Verschleiß sowie minimaler Wartungs- und Instandhaltungsaufwand. Gerade diese Merkmale sind in der Kraftfahrzeug-Serienfertigung von großer Bedeutung.In this case, a lifting device for an industrial processing station, in particular a lifting table for the promotion of a body shell in the automotive mass production, proposed, wherein the lifting device is designed for conveying a workpiece on a moving in a purely vertical upper frame. In this case, the lifting device has an isosceles Geradschubkurbel operated with a motor drive element as the first vertical guide. In this case, the isosceles Geradschubkurbel existing from a fixed bearing rocker with the swingarm bearings, a handlebar with the handlebar guide, a handlebar center joint and connected to the upper frame joint in the way that this is moved by the actuation of the attacking the fixed bearing rocker tie rod. In particular, through the use of an isosceles Geradschubkurbel, which is also known in the literature as "Scott-Russel mechanism", a simple and effective variant of a vertical guide system is given, which allows low heights with minimal manufacturing costs. Because of the small number of lifting elements involved in the vertical stroke, as well as because of the possible simple production engineering design of these lifting elements, the system complexity can be minimized compared to the prior art and thus significant advantages can be achieved. These include a flat, compact and robust design, simple and cost-effective production, high system availability, low wear and minimal maintenance and repair costs. It is precisely these features are of great importance in automotive mass production.

Ebenso können vorteilhaft zumindest zwei parallel angeordnete zweite Vertikalführungen mit koaxialer Anordnung der Gelenke vorgesehen sein.

In this case, in an advantageous variant, the first and the second vertical guide are connected to one another by means of a pull rod for synchronized vertical movement and preferably the motor drive element is connected to the drawbar by means of a drive rod via one of the vertical guides.
Eine geringe Bauhöhe ergibt sich, indem das motorische Antriebselement in horizontaler Richtung außerhalb einer von dem Oberrahmen abgedeckten Grundfläche angeordnet ist.A low overall height results from the fact that the motor drive element is arranged in the horizontal direction outside a base area covered by the upper frame.
Wegen der Einfach- und Robustheit sowie der Wartungs- und Instandhaltungsfreundlichkeit kommt vorzugsweise eine Exzenter-Antriebsscheibe in Verbindung mit einem Synchron- oder Asynchron- Getriebemotor zum Einsatz, wobei dieser vorzugsweise über eine mechanische Haltebremse verfügt.Because of the simplicity and robustness and the ease of maintenance and serviceability is preferably an eccentric drive pulley in conjunction with a synchronous or asynchronous geared motor is used, which preferably has a mechanical holding brake.
Das erforderliche Drehmoment des Antriebs und die Belastung der lastführenden Elemente kann vorteilhaft weiter verringert werden, indem zumindest ein Massenausgleichssystem vorgesehen ist. Dabei kann das Massenausgleichssystem als Energiespeicher eine mechanische Feder oder eine pneumatische oder hydropneumatische Speichereinrichtung umfassen.The required torque of the drive and the load of the load-carrying elements can advantageously be further reduced by providing at least one mass balance system. In this case, the mass balance system can comprise as energy storage a mechanical spring or a pneumatic or hydropneumatic storage device.
