３次曲線の再生のための値を形成する。BACKGROUND OF THE INVENTION The grinding machine for the edges of spectacle lenses, which is known from West German Patent Application No. 3316619, has an electronic data memory with the contour shape of the spectacle lenses as data quantity. In this case, in order to capture the value of the contour of the eyeglass frame opening, a detection rod is provided which is rotatable about a fixed vertical axis and which is provided with a detection pin, the free end of which is It is brought into contact with the inner peripheral surface of the opening of the spectacle frame. The spectacle frame itself is in this case mounted on a longitudinally slidable carriage, which is under the action of a spring against a positionally fixed part, whereby each rotation of the detection pin is carried out. The angle can be associated with a digitized radius, and both pairs of values, namely the rotation angle and the associated radius, are received in one memory, by means of which this corresponds to the corresponding spectacle lens edge grinder. Each part can be controlled. West German Patent Application Publication No. 26, which is the basis of the superordinate concept of claim 1 of the present invention
According to the 00497 specification, an electromechanical detection head is known for detecting the contour of the spectacle frame during the shaping and grinding of the spectacle lens. In this case, a detection member that is rotatable around its own axis and is movable in the axial direction is used. The electric signal transmitter used in this case, which is composed of a transducer arranged in a fixed position and a mover inserted in the transducer, uses a ball joint as a bearing of the detection member. At this time, a shaft that is movable in the axial direction of the detection member and rotatable about its own axis performs a staggering operation, and the amplitude of this operation is related to the rotational position of the shaft, and the groove of the eyeglass frame opening. Or form a value for the reproduction of the cubic curve of the lens to be ground.

る。Functions and Effects of the Invention A rotatable plate for holding an eyeglass frame and a detection pin to be engaged in a groove of the eyeglass frame are known. An advantage of the present invention is that the detection pin itself does not have to perform a rotational movement and can therefore be formed as a finger, which is also advantageous in comparison to conventional detection rollers, for example when the curvature lines of the grooves of the spectacle frame are different. It is advantageous in that its contact point with the detection member need not be changed at all. This is a disadvantage in the known example as the detection roller of the detection member becomes larger. Furthermore, the arrangement according to the invention has the advantage that a value based on a simple linear movement is detected, which makes it possible, for example, to use a direct-acting potentiometer, which corresponds to West German patent application publication no.
It is advantageous, unlike the signal or measurement value generator according to 00497, which generator is adapted to capture the wobbling movement of the disc associated with the detection rod.

The point 100 of the eyeglass frame opening 23 of 14a is the measurement value generator 36,3.
Not only does the lateral value a detected by 7 be specified, this value is further determined by the second measured value generator 30, 31.
The value detected by is also made to correspond. This point 100 of the eyeglass frame opening is also associated with the angle value “zero” in the control device 33, for example. On the other hand, the point 101 of the eyeglass frame opening is given a lateral value b, which corresponds to the corresponding vertical value of the position of the detection rod 21. As can be seen from FIG. 5, the spectacle frame opening 23 has reached position 23 'due to the rotation of the frame half 14a. For this purpose, the angle value α by which the plate 8 is rotated is determined in the control device 33 by means of the measured value generators 30, 31 and 3
Both data according to 6,37 are assigned, whereby each point of the spectacle frame opening or groove bottom 27 is defined by three measured values. Each of these measured values is recalled directly in the spectacle lens edge grinding machine or after being stored once and controls the parts of the grinding machine in the biaxial direction for peripheral surface grinding without the need for the use of templates. It is possible.
