Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an eyeglass processing method and an eyeglass frame, and more particularly, to an eyeglass shop which can omit frame shape measurement in an eyeglass shop.

[0002]

2. Description of the Related Art In eyeglass processing for obtaining eyeglasses, lens processing information necessary for eyeglass lens processing is obtained based on information including a prescription value of the eye of the eyeglass wearer and frame shape information of an eyeglass frame selected by the eyeglass wearer. Then, the eyeglass lens material is selected and processed based on the lens processing information, and the obtained eyeglass lens is framed in the eyeglass frame.

[0003] In this eyeglass processing, frame shape information is indispensable, and it is necessary for a processor to accurately grasp the frame shape information of various shapes, which is the most important condition required for comfortable eyeglass manufacturing. It is one.

According to the conventional method by which a processor knows the frame shape information, in the case of a rimless frame or a frame with a partial rim, a frame maker sends the frame in advance together with the frame shipment.
A three-dimensional plastic lens is supplied as frame data, and the spectacle manufacturer (for example, a spectacles store) takes out a template with a matching frame part number for the spectacle frame selected by the customer, and uses a lens processing device (edger). ) To perform edging by profiling.

[0005] However, as described above, in the method in which the frame shape information of the spectacle frame is held by the template, if the frame shape is simple, the type is small, and the manufacturing error is small, the desired frame can be easily obtained. It has the merit of being able to obtain information, but as in today, when the types of frames are greatly increased and the variations in shape are dramatically increased, it is necessary to hold all of them on a template. Has its own limitations.

For this reason, in recent years, an edger in which a frame shape measuring device and a lens processing device are integrated has been generally used. The edger directly measures the frame shape information on the frame shape measuring device side, and transmits the measured result to the lens processing device side. The lens processing apparatus performs desired lens processing by combining the frame shape information with lens information, prescription value, layout information, processing designation information, and the like and using the information as lens processing information. This eliminates the need to use a template as in the prior art. FIG. 14 is a diagram showing an outline of a conventional eyeglass processing method. FIG. 14 shows a case where the lens processing is performed at the store of the spectacle store and a case where the processing is performed by requesting a processing company.

[0007]

However, the method using the edger has the following problems.

First, in order to obtain frame shape information in this method, it is necessary to individually set all the frames selected by the customer in a spectacle shop in a frame shape measuring device and perform the frame shape measurement. This measurement requires a certain measuring technique and measuring time. That is,
In order to perform accurate measurement, it is required that the holding operation and the operation for accurately setting the frame on the measuring table and the accuracy and speed of the operation be performed.
The frame shape measuring device is generally a contact type in which a tracing stylus is traced while pressing a stylus against a lens groove of the frame. For this reason, at the time of measurement, it may be necessary to consider the deformation of the frame due to pressing. There is also a problem in maintenance management in consideration of stylus wear. Furthermore, when customers concentrate on the eyeglass store, a plurality of operations cannot be performed at one time, so that there is a problem that processing takes time. Further, in order to avoid this, having a plurality of edgers has a problem that the equipment cost becomes enormous, and it is difficult to secure the operation personnel and to maintain and manage the apparatus.

SUMMARY OF THE INVENTION The present invention has been made in view of the above background, and an object of the present invention is to provide spectacles capable of obtaining accurate frame shape information without performing frame shape measurement at a spectacle store, and enabling eyeglass processing.

FIG. 1 is a diagram showing an outline of a method for processing eyeglasses according to an embodiment of the present invention. Hereinafter, an eyeglass processing method and an eyeglass frame according to the first embodiment will be described with reference to FIG. As shown in FIG. 1, the eyeglass processing method according to the first embodiment includes (1) a frame manufacturing process, (2) a frame shape measuring process, (3) a frame information adding process,
It comprises (4) a frame information reading step, (5) a lens processing information creating step, (6) a lens processing step, and (7) a lens framing step. Hereinafter, these steps will be described. (1) Frame manufacturing process An eyeglass frame is manufactured in a frame factory. This manufacturing process depends on the type of frame material,
In the case of a plastic frame, a method is generally known in which a frame shape is processed into a metal mold, a rim molding in which a plastic raw material is poured, and a frame shape is cut out from a flat plate by a cutting device. In this case, first, a frame design is determined, and frame shape data is created. Then, frame processing design data for manufacturing is created, and the data is
The frame is manufactured based on the data. These manufacturing methods are performed using the main computer of the factory. (2) Frame Shape Measurement Step, The manufactured spectacle frame is set on a frame shape measuring machine to measure the frame shape. In this measurement, it is sufficient to obtain two-dimensional data if the frame has a simple shape, but it is preferable to obtain three-dimensional data for a complicated design (shape). Basically, if there is position data from the measurement reference point, those skilled in the art can calculate the frame shape by calculation, but use a three-dimensional cylindrical coordinate system as described later. . Furthermore, frame circumference, frame PD, frame nose width, frame
By entering information such as the A and B sizes that are the maximum widths of the left and right and top and bottom of the
More accurate shape data can be obtained. In particular, the index of the circumference and the angle formed by the left and right frame frames are unique points proposed by the present applicant. The rimless frame is 2
Be a dimension.

FIG. 2 is a view showing an example of a frame shape measuring machine. This frame shape measuring device includes a measuring unit 1 that measures the shape of the spectacle frame Fr of the spectacle frame F held so as not to move to a predetermined position by spectacle frame holding means (not shown). The measuring unit 1 includes a U-shaped turntable 2. The turntable 2 is connected to a motor 6 via a timing pulley (not shown), a timing belt 4 and another timing pulley 5 attached to a lower end surface thereof. Is driven to rotate in the Θ direction. The angle of this rotation is
Is detected by a rotary encoder 9 connected via a timing belt 7 and a timing pulley 8 to the timing pre (not shown) attached to the above-mentioned timing pre. The motor 6 and the rotary encoder 9 are mounted on the board 10 of the frame shape measuring machine (only a part is shown in FIG. ), And the timing pulley and the turntable 2 (not shown) are rotatably supported on the substrate 10 by bearings (not shown).

The turntable 2 of the measuring section 1 has two side plates 11,
12 and a rectangular central plate 13 connecting these two side plates. Between the side plates 11 and 12, two slide guide shafts 14, 15 are fixed in parallel. A horizontal slide plate 16 is slidably guided in the E direction along the slide guide shafts 14 and 15. For this guidance, the slide plate 16 has three rotatable slide guide rollers 17, 1 on its lower surface.
8 and 19 are provided. In this case, two slide guide rollers 17, 1 are attached to one slide guide shaft 14.
8, one slide guide roller 19 contacts the other slide guide shaft 15, and these slide guide rollers 17, 18, 19 roll along the slide guide shafts 14, 15.

The sliding plate 16 has a sliding direction E
The slide plate 16 is pulled toward one side plate 12. This constant load spring 20 is wound around a bushing 21,
And is fixed to the side plate 12. Constant load spring 20
Is attached to a slide plate 16. The constant load spring 20 has an operation of pressing a stylus 30 described later against the inner peripheral groove of the spectacle frame Fr.

The amount R of movement of the slide plate 16 in the direction E is measured by a reflective linear encoder 24 as a displacement measuring scale. The linear encoder 24 includes a scale 25 extending between the side plate 11 and the side plate 12 of the turntable 2.
And the slide plate 16 and the scale 25
And a flexible cable 28 for connecting to a detector 26 moving along. The amplifier 27 is connected to the side plate 12.
Attached to a bracket 29 fixed to the bracket.

The detector 2 is intoxicated by the movement of the slide plate 16.
6 moves while keeping a constant distance from the surface of the scale 25. In response to this movement, the detector 26 outputs a pulse signal to the amplifier 27 connected by the flexible cable 28. The amplifier 27 amplifies this signal and outputs it as a transfer fee R via a counter (not shown).

The slide plate 16 holds a stylus 30 as a tracing stylus. The stylus 30 is supported by a slide bearing in a sleeve 31 fixed to the slide plate 16 so as to be movable in the vertical direction (Z-axis direction) and rotatable. The stylus 30 has an abacus ball-shaped head 32, which comes into contact with the inner peripheral groove of the spectacle frame Fr by the action of the constant load spring 20, and rotates in the inner peripheral groove of the spectacle frame Fr by the rotation of the turntable 2. Move along.

At this time, the stylus 30 moves in the Z-axis direction according to the curve of the spectacle frame Fr. The Z-axis measuring device 33 formed as a displacement scale detects the amount of movement in the Z-axis direction. The Z-axis measuring device 33 is fixed to the slide plate 16 and controls the movement of the stylus 30 in the Z-axis direction by a built-in charge-coupled device (CCD) line image sensor disposed on both sides of the stylus 30 and a light source. A displacement amount Z is detected by a light emitting diode (LED).

Next, the operation of the frame shape measuring machine configured as described above will be described.

The spectacle frame F is fixedly held by spectacle frame holding means (not shown), the head 32 of the stylus 30 is brought into contact with the V-shaped inner peripheral groove of the spectacle frame Fr, and the motor 6 is rotated by a control device (not shown). . Thereby, the turntable 2 connected by the timing belt 4 rotates, and the stylus 30 rolls while contacting the inner circumferential groove of the spectacle frame Fr. The rotation of the measuring unit 1 is detected as a rotation angle (θ) by rotating the rotary encoder 9 connected by the timing belt 7. The amount of movement of the stylus 30 in the radial direction is detected by the linear encoder 24 as the amount of movement R of the slide plate 16 in the E direction, and the amount of movement of the stylus 30 in the vertical direction is determined by the Z-axis measuring device 33 as the amount of movement Z of the stylus 30 in the Z-axis direction. Is detected. The values θ, R,
Z is not measured continuously, but is measured intermittently at every predetermined increment of the rotation angle (θ). Therefore, this input coordinate value is hereinafter referred to as three-dimensional measured shape data (Rn, θ
n, Zn) (n = 1, 2, 3,..., N). N represents the number of measurements in one rotation. In this case, the subscript n
, (N = 1, 2, 3,..., N), etc., are spatially arranged in the order of the numerical value of the subscript n. When the turntable 2 meaning periodic data having a cycle of N makes one rotation, the spectacle frame holding means slides a predetermined amount while holding the spectacle frame F, thereby setting the stylus 30 to the other spectacle frame. Then, the shape of the other eyeglass frame is measured. Since the predetermined slide amount of the spectacle frame holding means is set to a predetermined value in advance, the relative positional relationship between the spectacle frames can be known from the set value and the measurement data of the left and right spectacle frames Fr. Expressing this set value three-dimensionally,
Let it be relative position data (δX, δY, δZ).

As shown in FIG. 3, the primitive three-dimensional measurement shape data (Rn, θn, Zn) is strictly data 41 representing the locus of the central axis of the head 32 of the stylus 30, and Since the shape of the inner peripheral groove is not shown, the envelope 4 drawn by the accurate spectacle frame shape (the portion in contact with the bottom of the inner peripheral groove)
3 (the calculation for finding this envelope is called offset calculation). Of course, in the case of a measuring device in which the stylus directly contacts the bottom of the inner peripheral groove of the spectacle frame, this offset calculation is unnecessary. FIG. 4 shows a flowchart of the frame shape data calculation method. The details are described in Japanese Patent Application Laid-Open No. 6-66556 filed by the present applicant.
No.

To obtain three-dimensional data by this frame shape measuring instrument, the frame is set as specified, the stylus 30 is rotated about a predetermined point, and the cylindrical coordinates of the bevel groove shape as shown in FIG. Value (Rn, θn, Z
n) (n = 1, 2, 3,..., N) is three-dimensionally detected,
Send data to computer. The computer smoothes the data (there is no need for smoothing), the center coordinates (a, b, c) of the toric surface, the base radius RB, the cross radius RC, and the toric surface as shown in FIG. , The unit vector (p, q, r) of the rotationally symmetric axis, the frame curve CV (the curvature of the spherical surface when the frame is considered to be on the spherical surface), the circumferential length FLN of the bevel groove, and 7, 8,
As shown in FIGS. 9 and 10, a frame PD (interpupillary distance) FPD, a frame nose width DBL, A and B sizes which are the maximum widths on the left and right and top and bottom of the frame, and an effective diameter E
D (two values of the maximum radius), an inclination angle TILT formed by the left and right frame frames, and the like are calculated. Then, these calculated data are confirmed on the screen display device of the computer. If there is a large disturbance in the data or a large difference between the left and right frame shapes, a message to that effect is displayed on the screen. If there is an error message indicating that there is a large disturbance in the data, check that there are no sticking objects in the frame grooves, that the seams of the frame are displaced, or that there is no measurement with a gap left open. And measure again. Also, when an error message indicating that there is a large difference between the shapes of the left and right frame frames is displayed, if the difference is permissible, enter that it is acceptable to keep the same, while if the difference is not permissible, For example, the shape of the spectacle frame may be corrected by hand and measured again, or an average of the left and right shapes may be obtained by calculation, and an isomorphization process may be performed using the obtained value as the spectacle frame shape value. .

The frame shape data thus obtained is
It is stored in the storage device of the computer. (3) Frame information adding step The frame information actually measured by the above-mentioned frame shape measuring instrument is not actual frame design data, but actual data actually measured by a frame manufacturer at the time of shipment. It is important that it is data. That is, since it is actually measured data, a manufacturing error with respect to a design value (for example, in the case of a plastic frame, a shape error due to a difference in polymerization shrinkage due to a variation between material lots, a variation in mold processing accuracy, Frame machining device).

On the other hand, on the frame maker side, the frame
The actual measurement data is sent to the above-mentioned frame via a personal computer and a server.
The system design program and the like are stored as data in the host computer of the factory. The host computer is further provided with a spectacle lens ordering program, a spectacle lens processing design program (including lens information of stock lenses), and a bevel processing design program, and a lens, frame data, and a design for preparing spectacles. , And a calculation program for creating all processing data and lens processing information. These data and calculation programs are CD-R
It can be converted to OM and installed in a personal computer of an eyeglass store for use in an eyeglass store.

The data stored in the computer is
All data of the frame transmitted to the IC chip manufacturing equipment
After the data is written on the chip, the chip is embedded in an appropriate place in the frame, for example, in an inconspicuous place of the temple, and is held by means such as bonding.

FIG. 11 shows an eyeglass frame 100 on which the frame information is mounted.
Is a lens, 103 is a rim, 104 is a yoke, 105 is a hinge, 106 is a temple, and 107 is an IC chip on which data is written.

In the present embodiment, an example is described in which an IC chip is used as a medium for recording all shape data of a lens frame. In the case of a complex frame shape, the amount of information increases,
At the present time, an IC chip is preferable as a medium capable of storing a large amount of memory, since the more the amount of information, the more accurate the frame information can be grasped. Or two-dimensional, QR
And the like, and are not particularly limited in principle.

As for the method of recording the frame shape information, it is not always necessary to mount all the frame-shaped data as in this embodiment. If a method has been established to extract the frame data from a database that stores and manages the frame data, if there is an identification symbol that can identify the frame individual, the identification number is used. Only the addition may be performed. In that case, the frame data from the database
As a method of pulling out the data, there is a method of accessing a personal computer of a spectacle store and a database of a frame maker through a line using a LAN, a VAN, the Internet, or the like. For example, the HOYA online system, the HOYA frame VAN system, and the like of the present applicant have already been used. Further, the frame data can be transferred to a recording medium (for example, a CD) without using the online method.
-ROM, floppy (registered trademark), etc.) and incorporate it into a user's personal computer. In other words, this is a method of providing frame data on a recording medium on the manufacturer side.

As a specific example of such an identification symbol assignment, for example, an identification symbol such as "NL059T XXXYYY" can be considered.

Here, "NL" is a manufacturer's model name and is an abbreviation for a trademark "New Readers". Also,
“059” is the model number of the design and means the 59th model. "T" represents the material of the frame, which means an abbreviation of titanium material. "XXX" Here, the production lot number is indicated by a numeral symbol. “YYY” indicates the individual number in the lot.

Further, in addition to the identification symbol, for example, specific symbol data indicating characteristics of the shape of the frame may be added. As a specific preferable example, there is “frame circumference measurement information”. This "frame circumference measurement data"
For example, when "data" is "50.08", if it is a bar code system, it can be incorporated by four digits code. In this case, if the spectacle store supplies in advance frame shape design values and basic shape data including the original perimeter from the manufacturer side, the design data becomes "50. If the actual measurement data is “50.08”, the meaning is:
It can be estimated that the shape has expanded for some reason and has been deformed. That is, the frame shape can be simulated by calculating the ratio of the changed circumference from the difference between the measured circumference and the design value and combining the calculated ratio with the basic shape data.

In addition, if the index can restore the shape, the same can be achieved by adding such a symbolic index to the frame.

Furthermore, by compressing the data to be held as only the processing error data for comparison with the design data, the amount of notation can be reduced. Also in this case, it is assumed that basic data (for example, design data) is held when restoring shape data.

As a method of adding to a frame, in addition to the method of embedding and bonding in a frame as in this embodiment, a tag may be attached, for example, as a tag. The frame may be directly engraved. Direct mounting involves the processing steps and the number of steps increases, but the history of the frames remains, so it can be used as the frame information of the existing glasses at the time of frame repair or replacement of glasses. . (4) Frame Information Reading Step Next, in the spectacle shop, the information written in the embedded IC chip for the frame selected by the customer using an information reading device connected to the computer at the spectacle shop side. Reading is performed to obtain frame-related information such as frame shape information. As described above, if necessary, the computer at the eyeglass shop is connected to the host computer at the manufacturer online to read information. As a result, frame-related information necessary for eyeglass lens processing is obtained. (5) Lens Processing Information Creation Step On the other hand, the prescription of the customer is determined based on data such as the consultation of the ophthalmologist and the results of the optometry. The prescription value differs depending on the type and value of the prescription value attached depending on the visual environment of the patient, but generally includes a corrected visual acuity value, an astigmatic axis, a distance between pupils, and the like.

Then, a lens is selected based on the above-mentioned prescription information and the like, and at the same time, the material of the lens (for example, plastic lens or glass), lens specification (spherical or aspherical), outer diameter, lens thickness and the like are determined. .

Processing information is determined by integrating the above information. Here, based on the information on the visual environment required by the customer, designation of the amount of inward or outward alignment, designation of bevel position, designation of slab-off processing in the case of a progressive lens, designation of mets processing (minimum thickness specification), etc. The processing designation is determined. If a calculation program for creating all lens processing information is stored in a personal computer installed in an eyeglass shop, all processed data is created only by the above data input. (6) Lens Processing Step Next, the processing information obtained as described above is sent to a processor computer online together with necessary order information. The processor selects a specified lens material based on the order data and performs lens processing. This lens processing is performed by a numerically controlled processing device such as an edger or an NC processing machine. In a lens processing apparatus, as is well known, first, edge rubbing is performed, and then beveling is performed to obtain a desired spectacle lens. FIG. 12 is a diagram showing a general procedure of lens processing. In addition, this lens processing company may be also used as the above-mentioned frame manufacturing factory, or may be a person who works in a completely different place.

In this embodiment, an example is described in which lens processing is also performed by requesting an external device. That is, in this case, the features of the present invention can be fully utilized, and the work at the spectacle store can be minimized.

However, the present invention is not limited to this, and includes a case where frame shape measurement is not performed at the spectacle store, but lens processing is performed at the spectacle store. FIG. 13 is a diagram showing an outline of a modified example of the eyeglass processing method according to the present invention.
As shown in FIG. 13, this modification is basically the same as the above-described embodiment, except that the lens processing is performed by an edger installed in an eyeglass shop instead of requesting an external contractor. .

According to this modified example, there is an advantage that a troublesome frame shape measurement need not be performed in an eyeglass shop. (7) Lens framing process After receiving the lens ordered from the processor, the frame is framed to complete the glasses. In the case of the modified example, the lens processed in the eyeglass shop is framed in a frame to complete the process.

[0040]

As described above in detail, according to the present invention, after the eyeglass frame is manufactured at the factory, the frame shape information is obtained, and the frame-related information or the frame-related information including the obtained frame shape information is obtained. Readout information capable of reading frame-related information is added to the spectacle frame, while the spectacle store side obtains frame shape information necessary for obtaining lens processing information, by adding the information added to the spectacle frame. By reading the frame-related information from the frame itself or the storage means, etc. as a clue, it is possible to obtain accurate frame shape information and perform eyeglass processing without measuring the frame shape at the spectacle store And a spectacle frame.
