Description
Die Erfindung betrifft eine Vorrichtung zum Umlegen einer Bördelkante eines Werkstücks durch Rollfalzen nach dem Oberbegriff des Anspruchs 1.The invention relates to a device for transferring a flanged edge of a Workpiece by Rollfalzen according to the preamble of claim 1.
Eine solche Vorrichtung ist aus dem Dokument JP 08 16 4433-A bekannt.Such a device is known from the document JP 08 16 4433-A.
Eine bekannte Vorrichtung zum Umlegen einer Bördelkante durch Rollfalzen (EP 0 577 876 B1) umfasst eine Werkzeugeinheit, die mittels eines Gelenkarmroboters gesteuert bewegbar ist. An der Werkzeugeinheit ist drehbar eine Falzrolle gelagert, die unter Druckaufbringung und mit bestimmter Winkelstellung entlang und in Anlage an der Bördelkante zu deren Umlegung rollbar ist.A known device for transferring a flanged edge by Rollfalzen (EP 0 577 876 B1) comprises a tool unit, which by means of a Gelenkarmroboters controlled is movable. On the tool unit is rotatably a Folding roller stored under pressure application and with certain angular position can be rolled along and in contact with the flanged edge to their assignment.
Das Werkstück mit der vor dem Falzvorgang bereits um etwa 90° abgekanteten Bördelkante wird in eine Halteeinrichtung zur Halterung des Werkstücks und zur Unterstützung des Bereichs der Bördelkante eingelegt. Zudem ist hier die Herstellung einer Fügeverbindung zwischen zwei Blechbauteilen gezeigt, wobei mit dem Falzvorgang die Bördelkante eines äußeren Blechbauteils um einen Rand eines zweiten Blechbauteils gebördelt wird.The workpiece with the pre-folding already folded by about 90 ° Bördelkante is in a holding device for holding the workpiece and inserted to support the area of the flanging edge. Besides, here is the production of a joint connection between two sheet metal components shown wherein with the folding process, the flanged edge of an outer sheet metal component to an edge of a second sheet metal component is crimped.
Der Falzvorgang erfolgt hier zweistufig, indem die zylindrische Falzrolle unter Druck mit einem Anstellwinkel dergestalt an der Bördelkante entlang geführt wird, dass diese in einer Vorfalzung um etwa 45° umgelegt wird. Anschließend wird für eine zweite Falzstufe die zylindrische Falzrolle mit ihrer Rollenachse geschwenkt dergestalt, dass für eine Endfalzung die Bördelkante vollständig um 90° umgelegt wird.The folding process takes place here in two stages, by the cylindrical seaming roller under Pressure with an angle of attack in such a way guided along the flanged edge is that this is folded in a Vorfalzung by about 45 °. Subsequently For a second folding stage, the cylindrical folding roller with its roller axis pivoted in such a way that for a final fold the crimping edge completely is folded by 90 °.
Für eine lagegenaue Führung der Falzrolle in der ersten Falzstufe als Vorfalzung wird eine mit der Falzrolle verbundene Stützrolle an einer Führungsbahn der Halteeinrichtung entlang geführt. Die von einem Gelenkarmroboter durchzuführende Führung ist dabei relativ einfach und genau zu erreichen. Die erforderliche anschließende Kippung der Falzrollenachse in Verbindung mit einem zweiten Abfahrvorgang entlang der Bördelkante erfordert dagegen aufwendige Maßnahmen. Insbesondere hebt durch diese erforderliche Kippung die Stützrolle von der Führungsbahn ab, so dass für die Endfalzvorgang eine genaue Stützrollenführung der Falzrolle nicht mehr zur Verfügung steht, was zu ungleichmäßigen und damit unbefriedigenden Falzungen führen kann.For a positionally accurate guidance of the folding roller in the first folding stage as Vorfalzung becomes a support roller connected to the folding roller on a guideway led the holding device along. To be carried out by an articulated arm robot Leadership is relatively easy and accurate to achieve. The required subsequent tilting of the folding roller axle in conjunction with a second Abfahrvorgang along the flanged edge, however, requires complex Activities. In particular, lifts through this required tilt the support roller from the guideway, so that for the Endfalzvorgang a exact support roller guide the folding roller is no longer available, what can lead to uneven and thus unsatisfactory folds.
Aufgabe der Erfindung ist es, eine gattungsgemäße Vorrichtung zum Umlegen einer Bördelkante eines Werkstücks durch Rollfalzen so weiterzubilden, dass mit weniger Aufwand ein gutes Falzergebnis erzielbar ist.The object of the invention is to provide a generic device for folding further develop a flanged edge of a workpiece by Rollfalzen so that With less effort a good folding result can be achieved.
Diese Aufgabe wird mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved with the features of claim 1.
Gemäß Anspruch 1 ist die Werkzeugeinheit am Antrieb um eine Schwenkachse schwenkbar gelagert und um einen bestimmten Schwenkwinkel in wenigstens zwei Arbeitspositionen schwenkbar. Den wenigstens zwei Arbeitspositionen ist jeweils eine an der Werkzeugeinheit drehbar gelagerte Falzrolle zugeordnet, wobei die wenigstens zwei, den Arbeitspositionen zugeordneten Falzrollen unterschiedlich ausgebildete und bezüglich der Bördelkantenumlegung unterschiedlich wirksame Falzrollenumfangsflächen aufweisen.According to claim 1, the tool unit on the drive about a pivot axis pivotally mounted and at a certain tilt angle in at least two working positions swiveling. The at least two working positions is in each case one on the tool unit rotatably mounted folding roller assigned, wherein the at least two, the working positions assigned Folding rollers differently formed and with respect to the Bördelkantenumlegung have different effective Falzrollenumfangsflächen.
Für eine wenigstens zweistufige Umlegung der Bördelkante wird für eine Vorfalzung die Werkzeugkante mit der ersten Falzrolle in deren Funktionsstellung an der Bördelkante entlang geführt. Für die anschließende Endfalzung wird dann die Werkzeugeinheit in die zweite Arbeitsposition geschwenkt und mit der zweiten Falzrolle in deren Funktionsstellung an der Bördelkante entlang geführt.For an at least two-stage assignment of the flanged edge is for a Vorfalzung the tool edge with the first folding roller in its functional position guided along the flanged edge. For the subsequent final folding is then the tool unit is pivoted to the second working position and with the second seaming roller in its functional position along the flanged edge guided.
Die verwendeten Falzrollen haben unterschiedliche, für den jeweiligen Vorgang wirksame Falzrollenumfangsflächen, mit denen insbesondere Vorfalzungen und die Endfalzung durchgeführt werden können. Die dazu erforderlichen unterschiedlichen Anstellwinkel der Falzrollenumfangsflächen bezüglich der Bördelkante werden somit erfindungsgemäß durch die unterschiedlich ausgebildeten Falzrollen zur Verfügung gestellt, die lediglich in ihre gerade erforderliche Funktionsstellung geschwenkt werden müssen. Damit kann mittels eines Robotergelenkarms die Werkzeugeinheit in allen Falzstufen über die gleiche Bewegungsbahn geführt werden, im Gegensatz zum Stand der Technik, wo komplizierte Änderungen der Bewegungsbahn des Robotergelenkarms in den einzelnen Falzstufen durch die Verkippungen der Falzrolle zu berücksichtigen sind.The folding rollers used have different, for the respective process effective Falzrollenumfangsflächen, with which in particular Vorfalzungen and the Endfalzung can be performed. The required different angle of the Falzrollenumfangsflächen with respect to the Bördelkante are thus inventively formed by the differently Folding rollers provided only in their just required Function position must be swiveled. This can be done by means of a Robot joint arm the tool unit in all folding stages about the same Trajectory are guided, in contrast to the prior art, where complicated changes in the trajectory of the robot articulated arm in the to consider individual fold levels by the tilting of the folding roller are.
Eine besonders einfache geometrische Anordnung ergibt sich gemäß Anspruch
2, indem die Rollendrehachsen der wenigstens zwei Falzrollen radial
zur Schwenkachse in einer senkrechten Ebene zur Schwenkachse ausgerichtet
liegen und den Schwenkwinkel einschließen. Die Schwenkachse wird für
einen Falzvorgang zweckmäßig etwa parallel zur aufgekanteten Bördelkante
und etwa senkrecht zur an die Bördelkante angrenzenden Werkstückfläche
eingestellt. Das Anfahren der unterschiedlichen Arbeitspositionen kann durch
Hin- und Herschwenken der Werkzeugeinheit um die Schwenkachse erfolgen.
Die Arbeitspositionen können jedoch auch durch ein Weiterdrehen in einer
Richtung angefahren werden, wobei dann die Schwenkachse als Drehachse
ausgebildet ist. Um die unterschiedlichen Falzrollen durch einfache Schwenkbewegungen
jeweils in ihre Funktionsstellung zu bringen, ist es erforderlich,
die zur Umlegung der Bördelkante wirksamen Falzrollenumfangsflächen etwa
im gleichen Abstand zur Schwenkachse anzuordnen. A particularly simple geometric arrangement results according to the
Grundsätzlich können die Falzrollenumfangsflächen der einzelnen Falzrollen jeweils entsprechend den vorliegenden Erfordernissen und Gegebenheiten hinsichtlich einer Vorfalzung und Endfalzung für bestimmte gewünschte Falzausbildungen ausgeführt sein. Für einfache gerade Falze sind gemäß Anspruch 3 die unterschiedlichen Falzrollenumfangsflächen in einfacher Weise als Kegelflächen mit unterschiedlichen Kegelwinkeln und/oder insbesondere für die Endfalzung als Zylinderflächen auszuführen, wodurch mit jeder der einzelnen Falzrollen unterschiedliche Anstellwinkel bezüglich der Bördelkante für eine zugeordnete stufenweise Rollfalzung erreichbar sind.In principle, the seaming roller peripheral surfaces of the individual folding rollers each according to the requirements and circumstances in terms of a pre-fold and final fold for certain desired fold formations be executed. For simple straight folds are according to claim 3 the different folding roller peripheral surfaces in a simple manner as conical surfaces with different cone angles and / or in particular for the Endfalzung as cylindrical surfaces perform, whereby with each of the individual Folding rollers different angles of attack with respect to the flanged edge for an associated gradual Rollfalzung can be achieved.
In einer besonders, bevorzugten konkreten Ausführungsform nach Anspruch 4 sind drei Falzrollen in einem Schwenkwinkelabstand von jeweils 120° vorgesehen. Eine erste Falzrolle ist dabei als Kegelrolle mit einer Kegelfläche für eine Umlegung der Bördelkante in einer ersten Vorfalzstufe um etwa 30° ausgelegt. Eine zweite Falzrolle ist entsprechend als Kegelrolle für eine zweite Vorfalzstufe mit einer Umlegung der Bördelkante um etwa 60° ausgelegt. Für die Endfalzung ist die dritte Falzrolle als Zylinderrolle ausgebildet.In a particularly preferred embodiment according to claim 4 three folding rollers are provided at a pivoting angle of 120 ° each. A first folding roller is a tapered roller with a conical surface for a Allocation of the flanged edge designed in a first pre-seaming step by about 30 °. A second seaming roller is accordingly a tapered roller for a second prefolding stage designed with a deflection of the flanged edge by about 60 °. For the Endfalzung is the third folding roller designed as a cylindrical roller.
Eine besonders vorteilhafte Weiterbildung wird mit den Merkmalen des Anspruchs
5 erreicht, indem koaxial zu den Falzrollen Stützrollen angebracht
sind, die sich auf einer vorgegebenen Führungsbahn an der Werkstück- Halteeinrichtung
abstützen und dort abrollen. Da für jede Falzstufe die selbe Bewegungsbahn
abgefahren wird und die unterschiedlichen Anstellwinkel bezüglich
der umzulegenden Bördelkante durch die Form der einzelnen Falzrollen vorgegeben
werden, kann in jeder Falzstufe die jeweilige Stützrolle an der selben
Führungsbahn abrollen, wodurch in jeder Falzstufe eine gute Führung vorgegeben
ist und ein insgesamt gutes Falzergebnis erzielt wird.A particularly advantageous development is with the features of the
Die Stützrollen werden in einer einfachen Ausführungsform nach Anspruch 6 drehfest, vorzugsweise integral und materialeinheitlich mit den Falzrollen verbunden und zur Schwenkachse hinweisend angeordnet, so dass sie an einer Führungsbahn neben der Bördelkante abrollen können.The support rollers are in a simple embodiment according to claim 6 rotatably, preferably integrally and materially connected to the folding rollers and arranged pointing to the pivot axis, so that they on a Rolling guide track next to the flanged edge.
Die Werkzeugeinheit ist nach Anspruch 7 als ein eigenständiges Bauteil aufbaubar und endseitig an einen Robotergelenkarm anflanschbar. Durch unterschiedliche Flanschausbildungen kann die selbe Werkzeugeinheit ggf. mit unterschiedlichen Robotergelenkarmen kombiniert werden.The tool unit can be built according to claim 7 as an independent component and at the end flanged to a robot articulated arm. By different Flanschausbildungen can the same tool unit possibly with different Robot joint arms are combined.
Die erfindungsgemäße Vorrichtung kann sowohl für eine einfache Bördelrandausbildung als auch gemäß Anspruch 8 für eine Fügeverbindung von zwei Blechteilen verwendet werden.The device according to the invention can be used both for a simple edging edge formation as well as according to claim 8 for a joint of two Sheet metal parts are used.
