Definitions
- the invention relates to a method and an apparatus for shaping the Peripheral edge of spectacle lenses and for the subsequent subsequent attachment of a facet with a driven eyeglass support shaft holding the eyeglass lens and one related to the spectacle lens holding shaft controlled movable machining tool.
- the processing pressure can be set so that it is at a large, the Radius touching the radius of the lens is just so large that a Slippage of the spectacle lens clamped in the spectacle lens holding shaft just avoided is, whereby the processing pressure can be increased with a smaller radius and this enlargement, on the one hand, from the permissible, due to the processing pressure the spectacle lens is dependent on the instantaneous torque exerted, on the other hand must not be so large that the lens is damaged or even destroyed.
- the processing print can be made using a quantity of data control a computer, which also processes the shape of the lens by means of this Controls amount of data.
- the control of the processing pressure can be controlled Change of the processing tool relative to the lens holding shaft Moving actuator transmitted torque cause, the change of the torque either by means of a torque-controlled servomotor or by means of a torque-controlled clutch between the servomotor and the deliverable Machining tool can be carried out.
- the invention is also based on the problem of a method and a device for shaping the peripheral edge of spectacle lenses and, if necessary, subsequent Attaching a facet to create a slippage in the Spectacle lens holding shaft clamped spectacle lens is avoided with certainty, and with which the shaping of the peripheral edge of glasses as quickly as possible Risk of breaking or damaging the glasses is feasible, this
- the method and the device are to be designed and constructed simply and none complicated control.
- a method of the type mentioned at the beginning suggested that the torque of the eyeglass lens support shaft be measured, the Shaping the peripheral edge of the rotating spectacle lens with a predeterminable adjustable power of the machining tool is performed if and as long as that Torque is less than or equal to a predetermined value and that on the lens effective force of the machining tool by reducing the speed of the Spectacle lens retaining shaft, if necessary to a standstill, is lowered if and as long as that Torque exceeds the specified value.
- the spectacle lens that is clamped into the spectacle lens holding shaft remains Machining force always below a predeterminable value, at which a slipping of the Eyeglass lenses certainly do not occur.
- This method has the advantage that it is independent of the control of the mold processing, if necessary also by retrofitting in a Eyeglass lens processing machine can be integrated. For example, that is The method according to the invention regardless of whether the shaping of the lens CNC-controlled or by copy grinding using a shaped disc.
- Measuring the torque of the spectacle lens holding shaft can be done in different ways perform, for example by measuring the torque of the drive motor Spectacle lens holding shaft. This torque is proportional to the current consumption, so that measuring the torque by measuring the current consumption of the drive motor can be achieved. Likewise, the torque of the drive motor on the housing of the Drive motor measure if this housing rotates slightly on an elastic Support is stored and the path of the elastic support is measured.
- the control of the rotational speed of the spectacle lens holding shaft can either take place in the manner that they are proportional to the exceeding of a predetermined value of the torque is reduced or by stopping the lens holding shaft for as long as a specified value of the torque is exceeded.
- the device for shaping the peripheral edge of spectacle lenses and for possibly then attaching a facet with a driven one holding the spectacle lens Spectacle lens holding shaft and one controlled with respect to the spectacle lens holding shaft Movable machining tool according to the invention has a measuring device for Measuring the torque of the lens holding shaft and a control device for the the force of the machining tool acting to reduce this force by reducing the speed of the lens holding shaft, if necessary to a standstill, if and as long as the torque exceeds a predetermined value.
- the control device can drive the spectacle lens holding shaft, in the sense of a Reduce the speed of the lens holding shaft, if necessary to a standstill.
- the measuring device for measuring the torque preferably has an elastic one Support of the rotatably mounted housing of the drive motor for the Spectacle lens holding shaft, being on the support with the control device cooperating displacement sensor can be arranged and the control device Decrease the speed of the lens holding shaft proportional to exceeding one predetermined path of the encoder.
- a particularly advantageous embodiment of the device according to the invention results itself when the elastic support is biased so that movement only at Exceeding the preload, i. H. of the predetermined torque occurs and at an electrical contact cooperates with the elastic support that the The power supply to the drive motor is interrupted when the pretension is exceeded.
- the method and the device according to the invention can be described in DE 196 16 Combine the method described in 536 A1, so that on the one hand the processing pressure in Dependence on the respective radius in the contact area of the machining tool touching glasses controlled from a large radius to a small radius is increased and, on the other hand, the speed of the spectacle lens holding shaft, if necessary, up to Standstill is reduced if and as long as the torque reaches the specified value exceeds.
- a processing tool in the form of a Shown grinding wheel package 1 to which one of two halves 2, 3 parallel to the axis existing lens holder shaft is arranged.
- a spectacle lens 5 Between the halves 2, 3 of the Spectacle lens holding shaft is a spectacle lens 5 provided with a block or suction cup 4 trapped.
- the shaping of the spectacle lens 5 takes place in such a way that the spectacle lens 5 is set in slow rotation by the spectacle lens holding shaft 2, 3 while the Grinding wheel package 1 rotates quickly.
- the distance between the Spectacle lens holding shaft 2, 3 with the clamped spectacle lens 5 relative to Grinding wheel package 1 corresponding to the shape of the spectacle lens to be processed a motion drive 15 controlled changes. It is also possible with fixed Grinding wheel package 1, the lens holder shaft 2 compared to the grinding wheel package 1 move.
- the spectacle lens holding shaft 2, 3 is driven by a gear motor 6 Gear sets 7, 8.
- the spectacle lens 5 must be driven by the gear motor 6 different torque can be rotated by the machining pressure between the Grinding wheel package 1 and the lens 5 and the respective radius of the lens 5 depends. If this torque exceeds a value known from experience, can a slipping of the clamped between the lens halves 2, 3. Glasses 5 occur, which must not occur under any circumstances, if the one to be processed Spectacle lens a near part aligned with respect to the optical axis or one cylindrical or prismatic cut, the axis position of the arrangement of the Spectacle glasses is specified in the spectacle frame.
- the respectively valid, maximum transferable torque is from the material of the Glasses and depending on their surface treatment.
- Highly anti-reflective glasses have, for example, a particularly low coefficient of friction compared to holding devices the lens holder shaft or attached blocks or suction cups.
- the housing of the geared motor 6 is rotatable in the lens processing machine stored and supported on an extension 9 on springs 10. These feathers are between fixed, adjustable abutments 1 arranged so that the springs 10 a adjustable bias can be given, which is a measure of that by the geared motor 6th deliverable torque is against a rotation of the housing of the geared motor 6 the force of the springs 10 occurs.
- a displacement sensor 12 is arranged parallel to the springs 10 and cooperates with a pin 13. Now becomes a certain, adjustable Torque of the geared motor 6 exceeded, a deflection of the pin 13 occurs opposite the encoder 12. This deflection is measured and transmitted to a Forwarded control device 14, the speed of the geared motor 6, if necessary, to Standstill.
- the bias of the springs 10 can be set so that from one determined torque, which is still below the permissible torque, a Deflection of the pin 13 occurs, via the displacement sensor 12 and the control device 14 causes a proportional reduction in the speed of the gear motor 6.
- a certain deflection, d. H. of a certain, higher torque the Control device 14 shut down the geared motor 6, and this geared motor 6 remains as long as the specified torque is exceeded.
- a particularly simple embodiment of the invention can consist in that instead a limit switch a limit switch in the area of the extension 9 or pin 13 is arranged is.
- This limit switch interrupts the power supply to the geared motor 6 if and as long a torque that can be set by the bias of the springs 10 is exceeded. As soon as the torque drops to or falls below the set value, closes the limit switch again, and the gear motor 6 continues the rotation of the Spectacle lens holding shaft 2, 3 on.
