Abstract
Description
Die Erfindung betrifft eine Vorrichtung zum Aufbringen eines Kunststoffstranges auf eine Unterlage, mit einem mit einem vertestigten flüssigen oder pastösen Kunststoff unter Druck beaufschlagten Düsenkopf mit mindestens einer Austragsdüse, über die der Kunststoff austragbar ist, wobei der Düsenkörper mittels einer Roboteranordnung entlang einer vorgegebenen Bahn führbar ist.The The invention relates to a device for applying a strand of plastic on a surface with a liquid or pasty plastic nozzle head pressurized with at least one discharge nozzle through which the Plastic can be discharged, the nozzle body using a robot arrangement can be guided along a predetermined path.
Werden, wie beispielsweise im Automobilbau Metallbleche montiert, treten konstruktionsbedingt häufig Stoßstellen oder Überlappungen auf. Metallbleche lassen sich u. a. durch Schweißen, Nieten oder Kleben miteinander verbinden. Insbesondere im Automobilbau wird häufig ein Punktschweißverfahren eingesetzt. Aber nicht nur an den Rändern von punktgeschweißten oder auch genieteten Blechen, sondern auch im Bereich von Bördelfalzen besteht eine Korrosionsgefährdung, der nach dem Stand der Technik dadurch entgegengewirkt werden kann, dass die betreffenden Überlappungsbereiche oder Bördelfalzen durch eine Schutzschicht abgedeckt werden. Geeignete Kunststoffe werden hierzu in Form einer Raupe auf die zu schützende Oberfläche aufgespritzt oder aufextrudiert, wozu eine dauerelastische aushärtbare Kunststoffmasse mittels einer handgeführten Pistole oder mittels eines Düsenkopfes, der am freien Ende eines Roboterarmes angeordnet ist, auf die gewünschten Metallteile aufgetragen wird.Become, such as mounting metal sheets in automotive construction often due to the design joints or overlaps on. Metal sheets can u. a. by welding, riveting or gluing together connect. Spot welding is often used, particularly in automotive engineering used. But not just on the edges of spot welded or also riveted sheets, but also in the area of seam folds there is a risk of corrosion, which can be counteracted according to the prior art, that the relevant overlap areas or flared folds be covered by a protective layer. Suitable plastics are sprayed onto the surface to be protected in the form of a bead or extruded, for which purpose a permanently elastic hardenable plastic compound a hand-held Gun or by means of a nozzle head, which is arranged at the free end of a robot arm, to the desired Metal parts is applied.
Insbesondere im Karosseriebau von Kraftfahrzeugen sind jedoch die Führungsbahnen, entlang denen der Kunststoff aufgetragen werden muss, selten geradlinig. Häufig muss der Düsenkopf entlang komplizierter Bahnen geführt werden, wobei idealer Weise der Abstand des Düsenkopfes zum Werkstück stets gleich bleibend gehalten wird, um unregelmäßig breite und/oder unregelmäßig dicke Aufträge zu vermeiden.In particular in car body construction, however, the guideways are along which the plastic must be applied, rarely straight. Frequently the nozzle head led along complicated tracks be, the ideal distance between the nozzle head and the workpiece always is kept constant to irregularly wide and / or irregularly thick assignments to avoid.
Ein weiteres Problem beim Auftrag solcher Kunststoffstränge ergibt sich daraus, dass, z. B. bei PKW-Karosserieteilen, die zu behandelnden Oberflächen teils schwer zugänglich sind und teils auch Hinterschneidungen aufweisen, die mit großvolumigen Düsenköpfen erst gar nicht erreichbar sind.On further problem arises when applying such plastic strands from the fact that, e.g. B. in car body parts, those to be treated surfaces sometimes difficult to access are and sometimes also have undercuts that only with large-volume nozzle heads are not available at all.
Auch die prinzipiell denkbare und teilweise schon technisch realisierte Anordnung von mehreren Düsen an einem Kopf schafft keine jeder Bearbeitungssituation adäquate Lösung.Also the in principle conceivable and partly already technically realized Arrangement of several nozzles on a head, no solution can be found that is adequate for every machining situation.
Es ist daher Aufgabe der vorliegenden Erfindung, eine Vorrichtung zu schaffen, welche konstruktiv einfach gebaut ist, leicht gehandhabt werden kann und die in Bezug auf die jeweiligen unterschiedlichen Bearbeitungsfälle eine optimale Ausrichtung zulässt.It is therefore an object of the present invention to a device create which is structurally simple, easy to use can be a and in relation to the different processing cases allows optimal alignment.
Diese Aufgabe wird durch die Vorrichtung nach Anspruch 1 gelöst, die erfindungsgemäß dadurch gekennzeichnet ist, dass der Düsenkopf zur Ausrichtung der gewählten Austragsdüse in Bezug auf die Unterlage, auf die der Kunststoffstrang aufgetragen werden soll, um eine Achse drehbar ist. Anstelle einer Vielzahl von Düsen, die einen Austrag von Kunststoffmassen in entsprechenden Richtungen ermöglicht, ist im vorliegenden Fall der Düsenkopf selbst drehbar angelenkt, so dass die Austragsrichtung durch Verstellung des Düsenkopfes in wesentlich einfacher Weise eingestellt werden kann.This Object is achieved by the device according to claim 1, the according to the invention is marked that the nozzle head to align the selected discharge nozzle in relation to the base to which the plastic strand is applied should be rotatable about an axis. Instead of a multitude of nozzles, the discharge of plastic masses in appropriate directions allows is the nozzle head in the present case itself rotatably articulated so that the discharge direction by adjustment of the nozzle head can be set in a substantially simple manner.
Die Drehbarkeit des Düsenkopfes um eine Achse kann nach einer weiteren Ausgestaltung der Erfindung auch mit der Maßnahme kombiniert werden, in dem Düsenkopf zwei unterschiedliche Austragsdüsen mit verschiedenen Ausströmcharakteristiken zu verwenden, beispielsweise eine Düse, die zum Austrag eines sogenannten Breitenstrahles mit einem Austragsabstand von 20 mm bis 60 mm oder eines sogenannten Dünnstrahles mit einem Austragsabstand von 40 mm bis 200 mm geeignet ist.The Rotation of the nozzle head according to a further embodiment of the invention also with the measure can be combined in the nozzle head two different discharge nozzles with different outflow characteristics to use, for example, a nozzle that is used to discharge a so-called Beam with a discharge distance of 20 mm to 60 mm or one so-called thin beam with a discharge distance of 40 mm to 200 mm is suitable.
Soweit mit Materialdruckreglern gearbeitet wird, kann der Abströmwinkel durch entsprechende Druckvariation gesteuert werden.So far If working with material pressure regulators, the outflow angle can be controlled by appropriate pressure variation.
Prinzipiell ist es möglich, die beiden vorgenannten Typen von Austragsdüsen parallel nebeneinander am Düsenkopf oder auf gegenüberliegenden Seiten des Düsenkopfes oder um einen Winkel bis zu 180° gegeneinander geneigt anzuordnen. Die Anordnung der Düsen zueinander ist auf dem Düsenkopfdurchmesser frei wählbar und kann von der jeweiligen Anwendung abhängig gemacht werden. Gegebenenfalls kann die Rotationsachse so gelegt werden, dass ohne weitere Linearverschiebung des Düsenkopfes von einer Austrittsöffnung auf die andere Austrittsöffnung umgeschaltet werden kann, die dann nach entsprechender Drehung des Düsenkopfes dieselbe Materialoberfläche mit einer anderen Düse bearbeiten lässt.in principle Is it possible, the two aforementioned types of discharge nozzles in parallel next to each other on the nozzle head or on opposite sides of the nozzle head or at an angle of up to 180 ° to each other to arrange inclined. The arrangement of the nozzles to each other is on the Nozzle head diameter freely selectable and can be made dependent on the respective application. Possibly the axis of rotation can be set in such a way that without further linear displacement of the nozzle head from an outlet opening to the other outlet can be switched, which then after appropriate rotation of the nozzle head same material surface with a different nozzle can be edited.
Vorzugsweise wird ein Servo- oder Schrittmotor zur Drehung des Düsenkopfes verwendet, der unmittelbar oder unter Zwischenschaltung eines Getriebes oder sonstiger drehmomentübertragender Elemente mit dem Motor verbunden ist.Preferably becomes a servo or stepper motor for rotating the nozzle head used directly or with the interposition of a gearbox or other torque transmitting elements is connected to the engine.
Selbstverständlich lässt sich diese Anordnung auch in der Weise realisieren, dass der genannte Düsenkopf endseitig eines Roboterarms angeordnet ist, der Bewegungen in mehreren Freiheitsgraden durchführen kann.Of course you can realize this arrangement in such a way that the said nozzle head is arranged at the end of a robot arm, the movements in several Perform degrees of freedom can.
