Description

Die Erfindung betrifft eine Tasteinrichtung zum Abtasten der Kontur von Brillengestellöffnungen für das Umfangschleifen von Brillengläsern nach dem Oberbegriff des Hauptanspruches.The invention relates to a scanning device for scanning the contour of eyeglass frame openings for the peripheral grinding of eyeglass lenses according to the preamble of the main claim.

Durch die DE-OS 33 16 619 ist eine Schleifmaschine für die Ränder von Brillengläsern mit einem elektronischen Daten­speicher bekannt, der die Umrißgestalt des Brillenglases in Form einer Datenmenge enthält. Zum Erfassen der Werte der Kontur der Brillengestellöffnung dient hierbei eine um eine stationäre Vertikalachse drehbare Taststange mit einem Tast­stift, dessen freies Ende am Innenumfang der Öffnung des Brillengestelles zur Anlage kommt. Das Brillengestell selbst ist hierbei auf einem längsverschieblichen Schlitten gelagert, der unter Wirkung einer Feder gegenüber einem stationären Teil steht, so daß jedem Drehwinkel des Taststiftes ein digitalisierter Radius zugeordnet werden kann und diese beiden Wertepaare, d. h. der Drehwinkel und der zugeordnete Radius, von einem Speicher übernommen werden können, von dem aus die entsprechenden Teile der Brillenglasrandschleifma­schine gesteuert werden können. - Durch die den Gattungsbe­griff des Hauptanspruches bestimmende DE-AS 26 00 497 ist ein elektromechanischer Tastkopf zum Abtasten der Kontur von Brillengestellen beim Formschleifen von Brillenglas­linsen bekannt. Hier findet ein um seine Achse drehbarer Taster Anwendung, der zudem noch axial beweglich ist. Der hierbei zur Anwendung gelangende elektrische, aus einem ortsfest angeordneten Wandler und einem in diesen ein­tauchenden Anker bestehende Signalgeber weist eine Lagerung des Tasters als Kugelgelenk auf, wobei der axial bewegliche und um seine Achse drehbare Schaft des Tasters eine Taumelbe­wegung ausführt, deren Ausschlag in Verbindung mit der Dreh­stellung des Schaftes die Werte für die Reproduktion der Raumkurve der Nut der Brillengestellöffnung bzw. des zu schleifenden Glases ergibt.From DE-OS 33 16 619 a grinding machine for the edges of glasses with an electronic data memory is known, which contains the outline shape of the glasses in the form of a data set. To detect the values of the contour of the eyeglass frame opening, a probe rod rotatable about a stationary vertical axis is used with a stylus, the free end of which comes to rest on the inner circumference of the opening of the eyeglass frame. The eyeglass frame itself is mounted on a longitudinally displaceable slide, which is under the action of a spring against a stationary part, so that a digitized radius can be assigned to each angle of rotation of the stylus and these two pairs of values, ie the angle of rotation and the assigned Radius, can be taken from a memory from which the corresponding parts of the lens edge grinding machine can be controlled. - From the generic term of the main claim DE-AS 26 00 497 an electromechanical probe for scanning the contour of eyeglass frames is known when shaping eyeglass lenses. Here, a button that can be rotated around its axis is used, which is also axially movable. The electrical signaling device used here, consisting of a fixedly arranged transducer and an armature immersed in it, has a mounting of the push button as a ball joint, the axially movable and rotatable shaft of the push button executing a wobble movement, the deflection of which in connection with the rotational position of the shaft gives the values for the reproduction of the spatial curve of the groove of the eyeglass frame opening or of the glass to be ground.

Der Erfindung liegt die Aufgabe zugrunde, die gattungsmäßige Einrichtung derart zu verbessern, daß mit konstruktiv ein­fachen, gut bedien- und überschaubaren sowie wenig Platz beanspruchenden Mitteln die die Raumkurve einer Brillenge­stellöffnung bestimmenden Werte ermittelt werden, um mit diesen gespeichert oder unmittelbar den Schleifvorgang durch­führen zu können.The invention has for its object to improve the generic device in such a way that with structurally simple, easy-to-use and manageable means that take up little space, the values determining the spatial curve of a spectacle frame opening are determined in order to be able to store them or to carry out the grinding process immediately .

Zur Lösung dieser Aufgabe sieht die Erfindung die Merkmale des kennzeichnenden Teils des Hauptanspruches vor. - Die Merkmale der Unteransprüche dienen der Verbesserung und Weiterentwicklung der Merkmale des Hauptanspruches.To achieve this object, the invention provides the features of the characterizing part of the main claim. - The features of the subclaims serve to improve and further develop the features of the main claim.

An sich sind drehbare, das Brillengestell tragende Platten und in die Nut des Brillengestells eingreifende Taststifte bekannt. - Die Erfindung bietet den Vorteil, daß der Tast­stift selbst keine Drehbewegung zu vollführen braucht und daher als Finger ausgebildet werden kann, der gegenüber be­kannten Tastrollen z. B. insofern vorteilhafter ist, als bei verschiedenen Krümmungen der Nut des Brillengestells die Berührungsstelle mit dem Tastorgan sich nicht oder nicht wesentlich ändert. Dieses ist bekanntermaßen der Fall, je größer die Tastrolle eines Tastorgans ist. - Darüberhinaus bietet die Erfindung den Vorteil der Ermittlung der Werte aufgrund von einfachen geradlinigen Bewegungen, so daß z. B. Linearpotentiometer Anwendung finden können, was im Gegen­satz zu dem Signal- oder Meßwertgeber der DE-AS 26 00 497 steht, bei welcher der Meßwertgeber die Taumelbewegung einer mit der Taststange verbundenen Scheibe zu erfassen hat.Rotatable plates supporting the spectacle frame and feeler pins engaging in the groove of the spectacle frame are known per se. - The invention has the advantage that the stylus itself does not need to perform a rotary movement and can therefore be designed as a finger, the z. B. is more advantageous in that at different curvatures of the groove of the eyeglass frame, the point of contact with the sensing element does not change or does not change significantly. As is known, this is the case the larger the sensing roller of a sensing element. - In addition, the invention offers the advantage of determining the values based on simple straight-line movements, so that, for. B. linear potentiometers can be used, which is in contrast to the signal or transducer of DE-AS 26 00 497, in which the transducer has to detect the wobble movement of a disk connected to the probe rod.

Die Vorrichtung nach der Erfindung weist einen runden Rahmen 1 auf, der aus einem L-förmigen Profilstück 2 gebildet ist, dessen horizontaler Schenkel 3 auf Stützen 4 ruht, die mit ihrem Fuß 5 auf einer stationären Unterlage 6 aufsitzen. Auf dem horizontalen Schenkel 3 des Profilstückes 2 liegt der Rand 7 einer runden Platte 8 auf, deren Kante 9 an dem senkrechten Schenkel 10 geführt ist. Die Platte 8 kann um ihre vertikale Mittelachse M in Richtung des Pfeiles 11 ge­dreht werden. Hierzu dient ein an der Stütze 4a vorgesehener Motor 12, dessen Antriebswelle 13 in geeigneter Weise in einen entsprechenden Teil der Platte 8 eingreift, um diese in horizontaler Ebene zu drehen.The device according to the invention has a round frame 1, which is formed from an L-shaped profile piece 2, the horizontal leg 3 of which rests on supports 4 which rest with their feet 5 on a stationary base 6. On the horizontal leg 3 of the profile piece 2 lies the edge 7 of a round plate 8, the edge 9 of which is guided on the vertical leg 10. The plate 8 can be rotated about its vertical central axis M in the direction of the arrow 11. A provided on the support 4a serves for this purpose Motor 12, the drive shaft 13 of which suitably engages in a corresponding part of the plate 8 in order to rotate it in the horizontal plane.

Die Platte 8 hat einen Durchmesser, der in der Lage ist, die eine Hälfte 14a eines Brillengestelles 14 zu tragen. Die Platte 8 kann auch ein Ausmaß haben, wodurch das gesamte Brillengestell, d. h. auch die zweite Brillengestellhälfte 14b auf der Platte aufliegt, z. B. auf der Plattenhälfte 8a nach Fig. 1.
Das Brillengestell 14, bzw. dessen Hälfte 14a wird durch Klemm- und Spannelemente 15 unverrückbar auf die Oberfläche 8a der Platte 8 gedrückt, die in Nähe ihrer Mittelachse M ein Lang- oder Ovalloch 16 aufweist, das vorzugsweise läng­liche oder ovale Form hat und deren Längsachse K in Richtung des Doppelpfeiles 17 (Fig. 1) gelegen ist.The plate 8 has a diameter which is able to carry one half 14a of an eyeglass frame 14. The plate 8 can also have a dimension whereby the entire spectacle frame, ie also the second spectacle frame half 14b, rests on the plate, e.g. B. on the plate half 8a of FIG. 1st
The spectacle frame 14, or its half 14a, is immovably pressed by clamping and clamping elements 15 onto the surface 8a of the plate 8, which has an elongated or oval hole 16 in the vicinity of its central axis M, which preferably has an elongated or oval shape and its longitudinal axis K is located in the direction of the double arrow 17 (Fig. 1).

Auf der Unterlage 6 ist ein Schlitten 18 in Richtung des Doppelpfeiles 17a (Fig. 3) parallel zur Längsachse K des Lang- oder Ovalloches in der Platte 8 verstellbar. Auf dem Schlitten 18, der einen Tragteil für die darauf angeordnete Büchse 19 bildet, ist die mit der allgemeinen Bezugsziffer 20 versehene Tasteinrichtung angebracht. Diese weist eine senk­rechte Taststange 21 auf, die in der Büchse 19 auf- und ab­bewegbar und dort geführt ist sowie unter Wirkung einer Feder 22 steht, deren eines Widerlager die Oberseite des Schlittens 18 und deren anderes Widerlager die untere Stirn­kante der Stange 21 bildet. Die Stärke der Feder 22 ist so gewählt, daß sie das Eigengewicht der Stange 21 ausgleicht oder weitgehend ausgleicht.On the base 6, a slide 18 is adjustable in the direction of the double arrow 17a (FIG. 3) parallel to the longitudinal axis K of the elongated or oval hole in the plate 8. On the carriage 18, which forms a supporting part for the bushing 19 arranged thereon, the probe device provided with the general reference number 20 is attached. This has a vertical probe rod 21, which can be moved up and down in the bushing 19 and guided there, and under the action of a Spring 22 stands, one abutment forms the top of the carriage 18 and the other abutment forms the lower end edge of the rod 21. The strength of the spring 22 is chosen so that it compensates for or largely compensates for the weight of the rod 21.

Das obere Ende der Taststange 21 ragt durch das Loch 16 der Platte 8 und durch die Öffnung 23 der Brillengestellhälfte 14a. Es trägt oberhalb der Platte 8 einen Taststift 24, dessen Längsachse parallel zur Richtung des die Bewegung des Schlittens 18 kennzeichnenden Doppelpfeils 17a gelegen ist, der eine längliche, fingerartige Ausbildung hat und entweder, wie in ausgezogener Linie in Fig. 3 erkennbar ist, leicht nach unter gebogen ist oder aber, wie strichpunktiert in Fig. 3 gezeigt ist, eine gerade Ausführung mit gleich­falls nach unten gerichtetem Ende besitzt. Das freie Ende 25 des Taststiftes besitzt spitzwinklig zueinander gelegene Seitenflächen und eine abgerundete Tastspitze 26, mit der der Taststift am Nutengrund 27 der Öffnung 23 der Gestell­hälfte 14a gleitet, wenn die Platte 8 mit Hilfe des Motors 12 um die Achse M gedreht wird. Hierbei ist die längsverschieb­liche Taststange 21 mit dem Taststift 24 undrehbar verbunden und die längsverschiebliche Taststange 21 über einen Nuten­keil 28, der in eine Nut 28a der Büchse 19 eingreift, gegen Drehen gesichert.The upper end of the push rod 21 protrudes through the hole 16 of the plate 8 and through the opening 23 of the eyeglass frame half 14a. It carries a stylus 24 above the plate 8, the longitudinal axis of which is parallel to the direction of the double arrow 17a which characterizes the movement of the carriage 18, which has an elongated, finger-like configuration and either slightly, as can be seen in the solid line in FIG. 3 is bent under, or, as shown in dash-dotted lines in Fig. 3, has a straight design with a downward end. The free end 25 of the stylus has acute-angled side surfaces and a rounded stylus 26 with which the stylus slides on the groove bottom 27 of the opening 23 of the frame half 14a when the plate 8 is rotated about the axis M by means of the motor 12. Here, the longitudinally displaceable probe rod 21 is non-rotatably connected to the stylus 24 and the longitudinally displaceable probe rod 21 is secured against rotation by means of a key 28 which engages in a groove 28a of the sleeve 19.

Die Taststange 21 trägt einen Ansatz, z. B. in Form eines Winkelstückes 29, dessen freies Ende 30 als Schleiffinger in ein Potentiometer 31 oder als Anker in eine elektromagne­tische Spule derart eintaucht, daß mit dem Verstellen der Taststange 21 um des parallel hierzu gerichteten Schenkels des Winkelstückes 29 ein der Höhenlage des Taststifts 24 entsprechender Meßwert über die Leitung 32 einer Steuerein­richtung 33 zugeführt wird.The probe rod 21 carries an approach, for. B. in the form of an elbow 29, the free end 30 dips as a grinding finger in a potentiometer 31 or as an armature in an electromagnetic coil such that with the adjustment of the probe rod 21 to the parallel leg of the elbow 29 one of the height of the stylus 24th Corresponding measured value is fed via line 32 to a control device 33.

Auf dem Schlitten 18, an dem in Richtung des Doppelpfeiles 17 eine Feder 34 angreift, deren Widerlager durch den Schlitten 18 und die Stütze 4a z. B. gebildet wird, ist ein weiteres Winkelstück 35 vorgesehen, dessen freier Arm 36 als Anker in einer elektromagnetischen Spule oder als Schleiffinger in einem Potentiometer 37 gleitet, wodurch ein weiterer Steuerimpuls über die Leitung 38 der Steuerein­richtung 33 zugeführt wird, der der Horizontalstellung des Taststiftes 24 entspricht. Die Steuereinrichtung 33 empfängt daher Meßwerte der genannten Weggeber 30, 31 und 36, 37, die dem Verstellen der Taststange 21 in einer senkrecht zur Brillengestellöffnung gelegenen Ebene entsprechen und ferner in der senkrecht zu dieser Ebene gelegenen horizontalen Richtung.On the carriage 18, on which in the direction of the double arrow 17 a spring 34 acts, the abutment by the carriage 18 and the support 4a z. B. is formed, a further angle piece 35 is provided, the free arm 36 slides as an armature in an electromagnetic coil or as a grinding finger in a potentiometer 37, whereby a further control pulse via line 38 of the control device 33 is supplied, the horizontal position of the stylus 24 corresponds. The control device 33 therefore receives measured values from the aforementioned displacement sensors 30, 31 and 36, 37, which correspond to the adjustment of the feeler rod 21 in a plane perpendicular to the spectacle frame opening and also in the horizontal direction perpendicular to this plane.

Der Motor 12 der Platte 8 ist als Winkelgeber über die Leitung 39 ebenfalls mit der Steuereinrichtung 33 verbunden, so daß von dieser nicht nur die beiden vorstehend genannten Daten der Bewegung des fingerartigen Taststiftes 24 in zu der Stange 21 axialer und hierzu senkrechter Richtung auf­genommen und gespeichert werden, vielmehr auch die Werte der jeweiligen Winkelstellung der Platte 8 gegenüber einer Null- oder Ausgangsstellung.The motor 12 of the plate 8 is also connected as an angle encoder via the line 39 to the control device 33, so that the latter not only records and stores the two aforementioned data relating to the movement of the finger-like stylus 24 in the axial and perpendicular direction to the rod 21 rather, the values of the respective angular position of the plate 8 with respect to a zero or starting position.

In Fig. 5 ist die auf die Zeichenebene projektierte Öffnung 23 der Brillengestellhälfte 14a nach Fig. 1 erkennbar. Der Punkt 100 der Brillengestellöffnung 23 der Brillengestell­hälfte 14a ist nicht nur ein durch den Meßwertgeber 36, 37 festgestellter lateraler Wert von der Größe a bestimmt, viel­mehr ist diesem Wert a auch ein Wert zugeordnet, der durch den zweiten Meßwertgeber 30, 31 festgestellt wurde. Diesem Punkt 100 der Brillengestellöffnung ist ferner z. B. der Winkelwert "Null" in der Steuereinrichtung 33 zugeordnet. Dem Punkt 101 der Brillengestellöffnung hingegen ist ein Lateralwert b gegeben, dem ein entsprechender Vertikalwert der Stellung der Taststange 21 zugeordnet ist. Wie Fig. 5 erkennen läßt, ist dabei die Brillengestellöffnung 23 durch Drehen der Gestellhälfte 14a in die Stellung 23ʹ gelangt. Das Winkelmaß α , um das die Platte 8 hierzu gedreht worden ist, wird den beiden vorstehend genannten Daten der Meßwert­ geber 30, 31 und 36, 37 in der Steuereinrichtung 33 zugeord­net, so daß jeder Punkt der Brillengestellöffnung bzw. des Nutengrundes 27 durch drei Meßwerte bestimmt ist. Diese Meß­werte lassen sich an der Brillenglasrandschleifmaschine un­mittelbar oder nach Speicherung reproduzieren und steuern die Teile der Schleifmaschine zum Umfangsschleifen ohne Anwendung einer Schablone in zwei Achsen.5 shows the opening 23 of the spectacle frame half 14a projected on the drawing plane according to FIG. 1. The point 100 of the eyeglass frame opening 23 of the eyeglass frame half 14a is not only a lateral value of the size a determined by the transducer 36, 37, but rather a value is assigned to this value a which was determined by the second transducer 30, 31. This point 100 of the eyeglass frame opening is also z. B. assigned the angle value "zero" in the control device 33. In contrast, point 101 of the eyeglass frame opening is given a lateral value b, to which a corresponding vertical value of the position of the feeler rod 21 is assigned. As can be seen in FIG. 5, the spectacle frame opening 23 has reached the position 23ʹ by rotating the frame half 14a. The angular dimension α by which the plate 8 has been rotated for this purpose becomes the measured value for the two data mentioned above encoder 30, 31 and 36, 37 assigned in the control device 33 so that each point of the eyeglass frame opening or the groove base 27 is determined by three measured values. These measured values can be reproduced on the spectacle lens edge grinding machine immediately or after storage and control the parts of the grinding machine for peripheral grinding without using a template in two axes.
