In this embodiment, when the lid 2073 is closed, the center of the template holder 2077 is positioned on the OR, and is in the {Ii+1 configuration, which coincides with the center of rotation of the probe section 2120, so that the geometric center of the template The center of rotation of the probe section 2120 coincides with the center of rotation.

With the template set as described above, press the input a trace switch, which will be described later. At this time, rotating base 2
Reference numeral 105 is located at a position where the moving direction of the tracing stylus drive unit 2150 coincides with the y-axis direction, and the tracing stylus driving unit 2150 is located at the base position O.

When the probe drive section 2150 is moved in the opposite direction to the frame measurement, the pin 21 implanted in the probe section 2120
32 comes into contact with the center arm 2002, and when it moves further, it pushes the center arm 2002, the right arm 2006, and the left arm 2009 apart. The rollers 2159 are connected to the guide portions 2160b to 2160a of the fixed guide plate 2160.

The left arm 2009 is fixed, the movable guide plate 2161 is easily moved to a predetermined position by the solenoid 2164, and the probe drive unit 2150'! i-Return to standard position. At this time, the guide portion 2'{6 of the fixed guide plate 2160
Since the height of oa and the guide portion 2162a of the movable guide plate 2161 are configured to be the same, the template measuring roller 2126 moves while maintaining a constant height until it comes into contact with the template. Subsequently, the pulse motor 2107 is rotated every predetermined number of unit rotation pulses. At this time, the measuring head part 2120 moves toward the guide shaft 201 according to the radius vector of the template.

(c) Unprocessed lens shape 2 (a> Configuration 11) A is the entire shape measuring section of the unprocessed lens to detect the curve value, edge thickness, etc. of the lens after grinding under predetermined conditions. It is a schematic diagram.The detailed structure will be explained based on FIGS. 12 to 13.

FIG. 12 is a cross-sectional view of the shape measuring section 5 of the unprocessed lens.
Figure 3 is a plan view.

A shaft 501 is rotatably mounted on a frame 500 by a bearing 502, and a DC motor 503 and bottom switches 504, 5
05 and a potentiometer 506 are respectively assembled.

A pulley 507 is rotatably attached to the shaft 501, and a pulley 508. Flanges 509 are respectively assembled.

A sensor plate 510 and a spring 511 are assembled to the pulley 507.

As shown in FIG. 14, a spring 511 is loosely attached to the booley 508 so as to sandwich a pin 512 therebetween. For this reason,
When the spring 511 rotates with the rotation of the pulley 507, the spring 511 is attached to the rotatable pulley 508.
It has a spring force that rotates the pin 512 that is rotated, and when the bottle 512 rotates in contrast to the spring 511, for example in the direction of the arrow, it applies a force that attempts to return the bottle 512 to its original position.

A pulley 513 is attached to the rotating shaft of the motor 503, and a belt 5 is hung between the pulley 513 and the pulley 507.
14, the rotation of the motor 503 is transmitted to the pulley 507.

The rotation of the motor 503 is controlled by photoswitches 504 and 505 by a sensor plate 510 attached to a pulley 507.
is detected and controlled.

The rotation of the pulley 507 rotates the pulley 508 to which the pin 512 is attached, and the potentiometer 5-0
The rotation of the boley 508 is detected by the boisometer 506 by a rope 521 that is hung between the rotation axis of the boley 508 and the pulley 520. The shaft 501 and the flange 509 rotate at the same time as the sharpening boot 508 rotates.

The spring 522 is for keeping the tension of the lobe 521 constant.

The feelers 523 and 524 are rotatably assembled to the measuring arm 527 by pins 525 and 526, respectively, and the measuring arm 527 is attached to the 7 flange 509.

The initial position and measurement end position of the measuring arm 527 are detected by the photoswitch 504. Also, the photoswitch 50
5 is the front refractive surface of the lens. The relief positions and measurement positions of the feelers 523 and 524 are detected for each of the rear refractive surfaces of the lens. The measurement end position by the photoswitch 504 and the position of relief of the rear refractive surface of the lens by the photoswitch 505 match. FIG. 15 is a diagram showing the correspondence relationship between the photoswitches 504 and 505.

As shown in FIG. 16, the measuring arm 527 is equipped with a 4-digit itqi 5 2 9 microswitch 528, and it is ready! There is a rotatable arm 531 having a rotatable feeler 530 on the l529, which is held in the direction of the arrow by a spring 532, and the position of the 7 feeler 530 is detected by a microswitch 528. The cover 533 prevents grinding water and the like from adhering to the measuring device, and the sealing material 534 prevents grinding water and the like from entering between the cover and the measuring device.

In this embodiment, a third feeler 530 is provided so as to come into contact with the lens edge, but when the lens is not suitable for processing, the feelers 523 and 524 often show abnormal data, so feeler = 530 is used. It is possible to omit it.

(b) 1! ! First, the motor controlled by the photoswitch 505
503, and rotate the measurement arm 527 from the initial position to compensate for the relief of the front refractor of the lens as shown in Figure 17-1.In addition, at the relief position 6, the lens is held. The positional relationship is such that when the carriage 700 moves in the direction of the arrow, the feeler 523 and the lens do not interfere, and the feeler 530 comes into contact with the lens bar.

Next, the lens L moves in the direction of arrow 535, and its amount is controlled by the shape data of the eyeglass frame or lens shape data that is inserted into the frame after lens processing. Based on these data, the lens moves in the direction of the arrow.

If the lens size does not deviate from the eyeglass frame shape data or lens shape data, the feeler 530 comes into contact with the lens edge and moves in the direction of arrow 535, and the microswitch 528 detects this. When the lens size is out of range, a signal from the microswitch 528 indicates on the display section 3 that grinding is not possible. Micro switch 528
When detecting the movement of the feeler 530, the motor 503 is rotated so that the feeler 523 comes into contact with the front refracting surface in order to measure the shape of the front refracting surface of the lens. The amount of rotation is based on the lens (75 - crotch thickness and feeler 53
1j 6 r) This state is shown in Figures 17-2 and 17.

It works so that it comes into contact with the front folding surface.

Next, when the lens is rotated once around the chuck shafts 704a and 704b, the lens moves in the direction of arrow 536 according to the shape data of the eyeglass frame or the lens shape data, and the feeler 523 moves in the direction of arrow 537. This amount of movement is detected by a potentiometer 506 via a rotating pulley 508 to obtain the shape of the front refractive surface of the lens. At the same time, the microswitch 52B measures whether or not the lenses can be processed into a lens shape according to the above data, and this is displayed.

After that, the carriage 700 is returned to the initial position, and the motor 5
03 roughly to the position where the rear refractive surface of the lens can be measured, and then move the lens to the measurement field.

While rotating the lens once, the amount of movement thereof is measured using the feeler 524 in the same manner as the measurement of the front refractive surface.

Furthermore, the measured shape data of the lens frame and template are temporarily stored in a trace data memory and transferred to the main arithmetic and control circuit.

(4> Operation of the mounting body Next, the operation of the lens grinding device will be explained based on the flowchart of FIG. 21.

After turning on the main switch 400 in FIG. 21, first, a frame or a template is set on the frame or template holder, and tracing is performed using the trace switch 416.

Step 1-2 Input the geisha's PD value and astigmatism axis. In the case of template measurement, the FPD value is also input. In addition, the distance changeover switch 4
06 is used to set whether the input PD is far or near. The setting status is displayed on the display of the display unit 3. Here, after inputting the far PD with the distance set to far, if it is changed to near using the perspective switching switch 406, it is converted to the near PD using the following equation.

e means the required working distance, 12 means the distance between the corneal apex and the corneal apex in Japanese people, and '13 means the distance between the corneal apex and the rotation point.

When 21'3 is in the near state and the near PD is input and then changed to the far one, it is converted to the far PD using the following formula.

Details of the conversion are described in Japanese Patent Application Laid-Open No. 63-826218.

Further, the upper and lower layouts are also set to the setting values input in advance in the above-mentioned reference value setting for each of the near and far areas. If you want to make changes to that value, click (
(10) Can be changed using switch 408 and (-) switch 409. At this time, the PD can also be changed.

Step 1-3 Using the radial information and FPD value of the frame or template obtained in Step 1-1 and the information on the PD top and bottom layout input in the previous step, coordinates are transformed to a new coordinate center using the method described above, and a new radial vector information (rsδn, rsθn) is obtained and stored in the frame data memory.

Step 1-4 The operator determines the material of the lens to be processed, and selects whether it is a glass lens or a plastic lens using the lens selection switch 40.
2, whether the frame is metal or cell, the frame changeover switch 403 selects whether it is a processed lens, right eye or left eye.
The L changeover switch 405 is used to input flat processing or bevel processing using the mode switch 404. Based on the setting values entered in advance in the standard value setting for each of 8 types of combinations depending on whether the lens is plastic or glass, the frame is cell or metal, and the mode is beveled or flat.
Set the lens size.

If you want to change the setting value, press the {+} switch 40.
8. (-) switch 4. Changes can be made at 09. If the R/L designation of the processed lens is the same as the measurement side at the time of frame measurement, the data is used as is, but if it is different, the data is reversed left and right and used.

Step 1-5 The lens is chucked by rotating the motor 706 using the switch 413 for opening and closing the lens chuck. At this time, if the lens has a directional property such as an astigmatic axis, it is turned so that the axial direction is directed toward the center of rotation of the grindstone.

Step 1-6. Step 1-7 If there is no abnormality in the above steps, start switch 41
Press 1 to start.

When confirming that the start switch 411 is pressed, the main arithmetic and control circuit performs processing correction (grinding wheel diameter correction).

Here, point a is the center of rotation of the grinding wheel, point b is the center of lens processing, and R
is the radius of the grindstone, LE is the frame data, and is the distance between the center of rotation of the grindstone and the center of lens processing. Here, the radial information (
rsδn, rsθn) @ read from frame data memory,
Perform the following calculations.

1=rs6rlcOs I'sθn+p"-(rs5
n sin rs&n )'(n=1.2.3...N
) When the astigmatism axis is other than 180°, offset Sθn by that difference and use that rsθ′n instead of rsθn.

Next, the radius vector information (rsδn, rsθn) is rotated around the processing center by a small arbitrary angle, and the same calculation as in the previous equation is performed.

The rotation angle of this coordinate is ξi (i = 1.2.3...
・N) and rotate 360° sequentially from ξi to ξ0. The maximum value of the slope at each ξi is li, and rs at that time is
θn is changed to (9i. Also, (Li ξiei) (i =
1.2.3...N) as processing correction information and stored in the frame data memory.

Step 2-1 If the designation in step 1-4 is the Yagunka mode, the process advances to Step 2-2, and if the designation is the Heiri D mode, the process advances to Step 3-1.

Step 2-2 When the beveling mode is specified, the main processing control circuit rotates the lens rotation axis motor 721 via the pulse generator and pulse motor driver, and rotates the lens so that rsθn points toward the center of rotation of the grinding wheel. Rotate the shafts 704a and 704b.

Next, the carriage is rotated by the motor 714 in the same manner,
After moving the carriage to the measurement reference position at the left end of the carriage stroke, the motor 728 is rotated to change L to a measurable position.

Thereafter, the lens edge position @ on the line of vector radius information is measured using the aforementioned unprocessed lens shape measuring mechanism. The lens front edge position thus determined is defined as rZn, and the lens rear edge position is defined as IZn. This is Koba information (lzn, r'zn) (
n=1, 2.3---N>, and store this in the frame data memory.

If it is determined that there is a part where the outer diameter of the lens is smaller than the lens diameter, it is determined that a lens with the desired lens frame shape cannot be obtained, a warning is displayed on the display, and execution of subsequent steps is canceled. do.

Step 2-3 Find the front curve and the rear curve from the edge information (IZn, rZn) obtained in Step 2-2.

First, the radial information (rs6n, rsθn) is converted into orthogonal coordinates (
Xn, Yn). Any four points (XY1
), (X2, Y2). (X3,Y3)(X4.Y4
> each edge information (IZ, +2.). (+
22. I22). (+23, IZ3>, (Z4 .
First, find the front curve and its center from (l Z4 ) 6 Here, (a, b, C) are the center coordinates of the curve, and R is the radius of the curve.

a=DI/D b=Dz/D Next, all IZ is replaced with "Z" to find the rear curve and its center. Based on this information, the bevel curve is found.

The bevel curve is the curve drawn by the apex of the V-groove on the outer periphery that is processed to fit the lens frame. Generally, a curve that follows the front curve is desirable, but if the bevel curve is too steep or too gentle, the frame may It is inconvenient to insert it. Therefore, if the front curve value is within a certain width, the bevel curve will form the same curve as the front curve. The position of the apex of the bevel shall be a certain distance to the rear from the edge position of the front surface of the lens. The center of the curve is placed on the line connecting the center of the curve of the front turnip and the center of the curve of the rear turnip.

If the bevel curve exceeds a certain width, the edge information (IZ
n, rZn), IZn + (rZn - IZn) R/1o = yzn to yZ
Find n. At this time, if R=4, it is equivalent to setting the edge thickness at a ratio of 4:6.

If a curve along the front curve is possible, the data is set as (rsθn, ylZn), and if it is not possible, R
The data obtained by setting =4 is set as (rsθn, V*Zn) and is used as a reversal date.

When the edge is thick, it may not be necessary to maintain the ratio along the front curve of the lens. In this case, the bevel data follows the frame curve.

Step 2-4 Display the bevel shape obtained in the above step on the display section 3.

On the display (radial information (rsδn, rSθn)
A frame shape is displayed, and a rotating cursor 30 roughly centered around the processing center is displayed. The yagun shank 32 at the position where this cursor and the frame shape are in contact is displayed on the panel I side. The cursor rotates to the right while the (+) switch is pressed and to the left while the (-) switch is pressed, and the bevel cross section at that position is always displayed.

When the rotation cursor is at the position indicated by the rim thickness measurement position mark 31, the rim position mark 33 is located at the upper left of the bevel cross section.
Display.

The bevel is positioned so that the front surface of the lens has a certain relationship with the front surface of the rim based on the measured rim thickness.

Step 2-5.2-6 If there is no problem after checking the bevel curve, start the process again using the start switch 400 to start machining.

According to the settings in step 1-4, the carriage 714 is moved by the motor so that the lens to be processed is placed on the plastic rough grindstone 60G if the lens is plastic, or on the glass rough grindstone 60a if it is glass.

After rotating the grindstone, the motor moves the distance between the center of rotation of the grindstone and the center of lens machining to the machining correction information (Li, ξi, O;>) read from the frame data memory. At that time, the machining is completed. Wait until the switch 727 is turned on, rotate the angle to ξ2, and at the same time turn L to L2.
move it to.

Continuously perform the above operations (Li.ξi) (i=12,3・
...Conducted based on N). As a result, the lens is processed into the shape of the radius vector information (rsδn, rsθn>).

Step 2-7.2-8.2-9 After the lens is removed from the grindstone by the motor 728, the lens is moved onto the bevel grindstone by the carriage moving motor 714.

Next, process correction information (L1, ξi, ■i) and A7 generation data (rs6n, rsθn) or (rsθn, ykZn
) to obtain the beveled data YZi.

Transformation G, i ma-fOi = rsθn and rsθn is 1-

Bevel position for sθth ffiy! Select Zn or ykzn sequentially and use it as Zi to obtain Yagun processing information (Liξr
zr> and then store it in the frame data memory again.

Based on this information, the motor 728 sets Li, the motor 721 sets ξi, and the motor 714 sets Zi, respectively.
+. 2.3 Processing is performed while controlling simultaneously in the order of N.

Step 3-1 When the grinding mode is the flat processing mode, the lens to be processed is placed on the rough grindstone for plastic 60a if the lens is plastic and the rough grindstone for glass 60a if it is glass according to the settings in step 1-4. The motor 714 moves the carriage. After rotating the grindstone, the motor 728 reads the distance L between the center of stone rotation and the center of lens processing from the frame data memory to perform processing correction tI.
Move to li in the z information (Liξiθi). At that time, wait until the machining end photoisolation 727 is turned on, rotate the angle to ξ2, and move L to L2 at the same time. Continuously perform the above operations (Lξi) (i=1.2.3
,...N>.

As a result, the lens is processed into the shape of the radius vector information (rs6n, rsθn).

Step 3-2.3-3 After the lens is removed from the grindstone by the motor 728, the lens LE is moved onto the flat part of the bevel grindstone 60c by the carriage moving motor 714. Here step 2
- Finish the outer periphery of the J: Re-lens LE in the same manner as below.
