Description
Die Erfindung bezieht sich auf eine Vorrichtung zur Bearbeitung von Brillengläsern mit wenigstens einer Bearbeitungsstation zur Bearbeitung des Randes und/oder einer Fläche des Brillenglases und einer mehrachsigen Positioniereinheit, mit einer Greifereinheit, die das Brillenglas ergreift und in die jeweilige Bearbeitungsstation einsetzt bzw. aus dieser entnimmt.The invention relates to a device for processing of spectacle lenses with at least one processing station to edit the edge and / or one Surface of the spectacle lens and a multi-axis positioning unit, with a gripper unit that holds the lens grips and inserts into the respective processing station or takes from this.
Brillengläser werden derzeit etwa wie folgt hergestellt:Eyeglass lenses are currently manufactured as follows:
Zunächst wird von dem eigentlichen Hersteller des Brillenglases ein sogenannter Blank gefertigt; hierunter versteht man ein einseitig fertiges und in der Regel rundes, in manchen Fällen aber auch vorgerandetes Brillenglas. Anschließend wird bei Vorliegen einer konkreten Bestellung eines Augenoptik-Fachgeschäftes entweder vom Hersteller selbst oder von einer sogenannten Rezeptglas-Schleiferei entsprechend der jeweiligen Verordnung die zweite Fläche, die deshalb auch als Rezeptfläche bezeichnet wird, gefertigt.First, the actual manufacturer of the glasses a so-called blank is made; this means one finished and generally round, in in some cases, pre-rimmed glasses. Subsequently when a specific order is available of an optics shop either from the manufacturer itself or from a so-called prescription glass grinding shop the second area according to the respective regulation, which is therefore also called the recipe area.
Dieses noch runde bzw. erst vorgerandete, aber beidseitig fertige Brillenglas wird dann an den jeweiligen Augenoptiker geschickt, der die Randung des Brillenglases entsprechend der von den Kunden ausgewählten Fassung vornimmt. This is still round or only pre-margined, but on both sides The finished lens is then sent to the respective optician sent, which corresponds to the rim of the lens the version chosen by the customer.
Zur Einsparung von Arbeitsschritten und/oder Kosten wird in der letzten Zeit verstärkt versucht, die Bearbeitungsschritte "Herstellen der Rezeptfläche" und "Randen des Brillenglases für die ausgwählte Fassung" in ein und derselben Betriebsstätte und nach Möglichkeit in ein und derselben Vorrichtung vorzunehmen.To save work steps and / or costs Lately trying to edit steps "Making the Recipe Area" and "Edge of the Eyeglass lenses for the selected frame "in one and the same Permanent establishment and if possible in one and the same device.
Vor kurzem ist in einer älteren Patentanmeldung der Anmelderin der vorliegenden Anmeldung, der Wernicke & Co. GmbH, vorgeschlagen worden, zur weiteren Kosteneinsparung die Handhabung der Brillengläser insbesondere in den Randungsvorrichtungen mittels eines Industrieroboters, also einer mehrachsigen Positioniereinheit, zu automatisieren.Recently in an earlier patent application by the applicant the present application, Wernicke & Co. GmbH, have been proposed to further reduce costs Handling of the glasses in particular in the edge devices by means of an industrial robot, i.e. one multi-axis positioning unit, to automate.
Eine dem Oberbegriff des Anspruchs 1 entsprechende Vorrichtung ist z.B. aus der EP-A-0 175 431 bekannt.A device corresponding to the preamble of claim 1 is e.g. known from EP-A-0 175 431.
Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zur Bearbeitung von Brillengläsern mit wenigstens einer Berarbeitungsstation zur Bearbeitung des Randes und/oder einer Fläche des Brillenglases derart weiterzubilden, daß eine einfache Handhabung eines Brillenglases und insbesondere das Einsetzen dieses Brillenglases in eine Randungs- und/oder Flächenbearbeitungsvorrichtung möglich ist.The invention has for its object a device for processing glasses with at least one Processing station for processing the edge and / or to develop a surface of the spectacle lens such that easy handling of glasses and in particular inserting this lens into a border and / or Surface processing device is possible.
Eine erfindungsgemäße Lösung dieser Aufgabe ist im Patentanspruch 1 angegeben. Weiterbildungen der Erfindung sind Gegenstand der Unteransprüche.An inventive solution to this problem is in the claim 1 specified. Developments of the invention are Subject of the subclaims.
Die Erfindung geht von dem Grundgedanken aus, Brillengläser mit Sauggreifern handzuhaben. Sauggreifer sind zur Handhabung von Gegenständen allgemein bekannt, jedoch für die Handhabung von Brillengläsern bislang nicht in Betracht gezogen worden. The invention is based on the basic idea of glasses to handle with suction pads. Suction pads are for Handling of objects generally known, however for the handling of eyeglass lenses has so far not been considered been drawn.
Der Grund hierfür dürfte sein, daß allgemein das Vorurteil besteht, Sauggreifer könnten nur auf ebenen und nicht auf konvexen oder konkaven Flächen, wie sie bei Brillengläsern in der Regel vorliegen, aufgebracht werden.The reason for this is likely to be that general prejudice exists, suction cups could only on level and not on convex or concave surfaces, as is the case with spectacle lenses usually present, be applied.
Da die (Begrenzungs-)Flächen eines Brillenglases häufig sogar eine von der rotationssymmetrischen Form abweichende Form, beispielsweise eine torische Form oder eine rein asphärische Form wie bei progressiven Brillengläsern haben, weist die erfindungsgemäß ausgestaltete Greifereinheit mehrere, vergleichsweise kleine Sauggreifer auf. Auch bei der progressiven Fläche eines progressiven Brillenglases kann dann davon ausgegangen werden, daß die Fläche über den Bereich, an dem der jeweilige Sauggreifer angreift, annähernd rotationssymmetrisch ist, so daß die sogenannte "Glocke" des Sauggreifers voll an der Fläche anliegt.Because the (delimiting) surfaces of a lens often even one that deviates from the rotationally symmetrical shape Form, for example a toric form or a pure one have an aspherical shape like progressive lenses, assigns the Gripper unit designed according to the invention, comparatively small suction pads. Even with the progressive surface of a progressive lens can then it can be assumed that the area over the Approximate area where the respective suction gripper is attacking is rotationally symmetrical, so that the so-called "Bell" of the suction cup is fully against the surface.
Weiterhin ist es erfindungsgemäß von Vorteil, wenn die Greifereinheit zwei "Scharen" von Sauggreifern aufweist, die längs einer geraden oder gebogenen Linie angeordnet sind. Insbesondere können die beiden Scharen von Sauggreifern längs der beiden Seiten eines "U" angeordnet sein.Furthermore, it is advantageous according to the invention if the Gripper unit has two "coulters" of suction pads, which are arranged along a straight or curved line are. In particular, the two groups of suction cups be arranged along the two sides of a "U".
Bei einer weiteren Ausbildung der erfindungsgemäßen Greifereinheit ist es möglich, einzelne Sauggreifer abzuschalten und/oder in Aufsetzrichtung zurückzuziehen, so daß auch unregelmäßig geformte Brillengläser, wie sie für extreme Brillenfassungen erforderlich sind, sicher gehandhabt werden können.In a further embodiment of the gripper unit according to the invention it is possible to switch off individual suction cups and / or withdraw in the direction of touchdown so that also irregularly shaped glasses, such as those for extreme glasses frames are required, handled safely can be.
Die erfindungsgemäß ausgebildete Greifereinheit kann beispielsweise bei der Automatisierung einer bekannten Randungsvorrichtung auf die konkave Seite des Brillenglases aufgesetzt werden, wobei auf die konvexe Seite in bekannter Weise ein sogenannter Block zum Halten des Brillenglases in der Randungsvorrichtung aufgesetzt ist. Die erfindungsgemäß ausgebildete Greifereinheit erlaubt damit beispielsweise das Aufnehmen eines zu randenden Brillenglases aus einer Zentriereinheit, in der der Block aufgesetzt worden ist, ohne daß eine Bedienungsperson den Einsetzvorgang des Brillenglases in die Bearbeitungsstation überwachen müßte.The gripper unit designed according to the invention can, for example in the automation of a known edge device on the concave side of the lens be placed on the convex side in known Way a so-called block for holding the glasses is placed in the edge device. The Gripper unit designed according to the invention thus allows for example, the inclusion of a lens to be edged from a centering unit in which the block is placed has been made without an operator performing the insertion process of the glasses in the processing station would have to monitor.
