Description

[Technical Field]

[0001] The present disclosure relates to a work data management apparatus and a work data management program for spectacle lens processing used for edging of spectacle lenses. [Background Art]

[0002] In edging of spectacle lenses, when a spectacle store has no spectacle lens in stock, a lens processing center (hereinafter referred to as a lab) that intensively performs edging on a large number of spectacle lenses is used (see, for example, Patent Document 1). In this case, at the spectacle store, the rim of the spectacle frame selected by the spectacle wearer (customer) is measured by a spectacle frame shape measuring apparatus (tracer), and the obtained target lens shape data that is the measurement result and the layout data (positional relationship data of the optical center of the spectacle lens relative to the target lens shape) as well as processing setting data are transmitted to the lab together with lens order data.

[0003] In the lab, based on the transmitted data, work data necessary for lens processing including the target lens shape data is created, and the work data is transmitted to the work data management apparatus. In the work data management apparatus, after the transmitted work data is processed, the work data is transmitted to the spectacle lens processing apparatus, so that the peripheral edge of the spectacle lens is processed by the spectacle lens processing apparatus.

[0004] When a spectacle store has no spectacle frame in stock, the spectacle frame may be ordered together with the spectacle lens by the identification number of the spectacle frame (see, for example, Patent Document 2). In this case, in the lab, work data including target lens shape design data obtained based on the identification number of the frame is created. Thereafter, a blank spectacle lens is prepared based on the target lens shape design data and the like. In addition, the actual spectacle frame is prepared based on the frame model number, and the rim shape of the frame is measured by the spectacle frame shape measuring apparatus, so that the actually measured data of the target lens shape is obtained by the work data management apparatus. [Prior Art Documents] [Patent Documents]

[0005] [Patent Document 1] Japanese Patent Publication No. 2000-94283 [Patent Document 2] Japanese Patent Application Publication No. 10-186293 [Overview of the project] [Problems that the invention aims to solve]

[0006] However, in conventional laboratories, once the actual lens shape data was obtained by measuring the rim of an actual eyeglass frame using an eyeglass frame shape measuring device, it was necessary to create new work data associated with that lens shape data. Therefore, the worker had to recreate the work data by inputting related information such as processing setting data (layout data, characteristic information of ordered lenses, etc.) other than the lens shape data included in the initial work data, so that it was associated with the actual lens shape data. In this case, the work was time-consuming and prone to input errors.

[0007] In view of the above-mentioned prior art, the technical objective of this disclosure is to provide a work data management device and a work data management program for eyeglass lens processing that eliminate the need for workers to recreate work data and enable more appropriate management of work data. [Means for solving the problem]

[0008] (1) A typical embodiment of the present disclosure provides a work data management device for processing the periphery of eyeglass lenses based on order data for lens processing from an eyeglass store, comprising: a first acquisition means for acquiring work data for lens processing, which includes design data for a lens shape corresponding to an eyeglass frame ordered by an eyeglass store and processing setting data included in the order data; a second acquisition means for acquiring measured data for a lens shape obtained by measuring the contour shape of the rim of the eyeglass frame; and a processing means for processing the work data, wherein the processing means overwrites the design data for a lens shape included in the work data acquired by the first acquisition means with the measured data for a lens shape acquired by the second acquisition means. (2) A typical embodiment of the present disclosure provides a work data management program that is executed by a work data management device for processing the periphery of eyeglass lenses based on order data for lens processing from an eyeglass store, and is characterized by causing the work data management device to execute: a first acquisition step of acquiring lens processing work data including design data of a lens shape corresponding to an eyeglass frame ordered from an eyeglass store and processing setting data included in the order data; a second acquisition step of acquiring measured data of a lens shape obtained by measuring the contour shape of the rim of the eyeglass frame; and a processing step of processing the work data, wherein the measured data of the lens shape acquired in the second acquisition step overwrites the design data of the lens shape included in the work data acquired in the first acquisition step. [Brief explanation of the drawing]

[0009] [Figure 1] This is a diagram showing the configuration of a communication processing system for eyeglass lenses. [Figure 2] This is a flowchart of the operation in an embodiment of the present disclosure. [Modes for carrying out the invention]

[0010] [overview] A typical embodiment will be described below with reference to the drawings. The items classified in <> below can be used independently or in relation to each other.

[0011] The work data management device (e.g., work data management device 40) relating to this disclosure is used for processing the edges of eyeglass lenses based on order data for lens processing from eyeglass stores (e.g., eyeglass store 10). For example, the work data management device is installed in a lab (e.g., lab 20), which is a lens processing center that centrally processes the edges of a large number of eyeglass lenses. For example, the lab is equipped with a core server (e.g., core server 22) that functions as a host computer, a database (e.g., database 24), and an eyeglass lens processing system (e.g., eyeglass lens processing system 30). For example, the core server is configured to receive information regarding lens orders, including lens processing, from ordering terminals (e.g., ordering terminal 12) of eyeglass stores, and to manage the order data related to the received lens orders. For example, the eyeglass lens processing system includes the work data management device. Furthermore, the spectacle lens processing system may also include a spectacle frame shape measuring device (e.g., spectacle frame shape measuring device 50), a cup mounting device (e.g., cup mounting device 60), and a spectacle lens processing device (e.g., spectacle lens processing device 70).

[0012] For example, the work data management device includes a first acquisition means (e.g., a control unit 42), a second acquisition means (e.g., a control unit 42), and a processing means (e.g., a control unit 42). The work data management device may also include a storage means (e.g., a storage unit 44). Furthermore, the work data management device may also include an output means (e.g., a control unit 42) for outputting data.

[0013] For example, the first acquisition means acquires lens processing work data created to include design data for the lens shape corresponding to the eyeglass frame ordered from the eyeglass store, and processing setting data included in the lens order data. For example, the first acquisition means acquires design data for the lens shape corresponding to the eyeglass frame based on the identification number of the eyeglass frame. For example, the identification number of the eyeglass frame may include the model number or model name of the eyeglass frame. For example, the work data is created by the core server and acquired by the first acquisition means. The work data is so-called job data and may include data related to lens characteristics such as the power of the ordered eyeglass lens and the lens material, as processing-related information necessary for lens edge processing. For example, the processing setting data is the processing condition data for the eyeglass lens processed by the eyeglass lens processing device. For example, the processing setting data includes layout data for the lens shape (data on the positional relationship of the optical center of the eyeglass lens to the lens shape). Also, for example, the processing setting data may include the lens material in the edge processing of the eyeglass lens, the type of eyeglass frame rim (metal, acetate, semi-rimless, two-point, etc.), whether or not chamfering is performed, whether or not mirror polishing is performed, etc.

[0014] For example, lens processing work data is processed by the core server into a format that can be received by the eyeglass lens processing machine. Of course, lens processing work data may also be created by a work data management device based on lens processing-related data transmitted from the core server.

[0015] For example, the second acquisition means acquires actual lens shape data obtained by measuring the contour shape of the rim of the eyeglass frame, which has been prepared based on the identification number of the eyeglass frame, using an eyeglass frame measuring device. The actual lens shape data acquired by the second acquisition means may be modified into a format that can be processed in subsequent processes, as long as it is based on data measured from the rim of the actual eyeglass frame into which the eyeglass lens will be fitted.

[0016] For example, the processing means updates the work data by overwriting the design data of the ball shape included in the work data acquired by the first acquisition means with the measured ball shape data acquired by the second acquisition means. This eliminates the need for the worker to recreate the work data and allows for more appropriate management of the work data. Note that the overwriting process may also be described as replacing or swapping the design data of the ball shape with the measured ball shape data.

[0017] Furthermore, the work data acquired by the first acquisition means may be assigned a work number. In this case, the processing means may not change the work number assigned to the work data even when it overwrites the design data of the lens shape with the measured data of the lens shape. This allows the work number assigned when the initial work data was created to be used as is in the laboratory's spectacle lens processing system, enabling proper data management and work management associated with the work number. The work number assigned to the work data only needs to be an identifier to identify the work data.

[0018] For example, the measured data of the lens shape may be obtained by a second acquisition means in association with the work number assigned to the work data. In this case, the processing means may overwrite the design data included in the work data that has been assigned the work number associated with the measured data of the lens shape with the measured data. This ensures that even when there are many work data with assigned work numbers, the measured data of the lens shape obtained by the spectacle frame shape measuring device is identified in correspondence with the work number, and the measured data is appropriately overwritten with the design data.

[0019] For example, the storage means may store work data with assigned work numbers. In this case, when measured data is acquired in association with the work number, the processing means may retrieve the work data from the storage means based on the work number and overwrite the design data of the sphere contained in the retrieved work data with the measured data of the sphere.

[0020] Further, for example, the receiving means may be configured to receive actual measurement data of the lens shape of an eyeglass frame measured by an eyeglass frame shape measuring apparatus together with a work number. In this case, the work data with the work number attached is stored in the storage means in association with the work number, and the second acquisition means may acquire the actual measurement data received by the receiving means. Then, the first acquisition means may be configured to acquire the work data by recalling the work data corresponding to the work number received by the receiving means from the storage means.

[0021] Further, for example, the output means may be configured to output updated work data obtained by overwriting the actual lens shape measurement data on the lens shape design data to at least one of a cup attaching apparatus and an eyeglass lens processing apparatus. Thereby, in the cup attaching apparatus and the eyeglass lens processing apparatus, processing necessary for peripheral processing of an eyeglass lens can be performed more appropriately based on the updated work data.

[0022] Further, the overwriting processing of the actual lens shape measurement data may include a case where the actual lens shape measurement data is associated (linked) with the work number instead of completely erasing the lens shape design data. For example, when the work data acquired by the first acquisition means is attached with a work number, and the actual lens shape measurement data is associated (linked) with the work number and acquired by the second acquisition means, the overwriting processing by the processing means may include processing of replacing the lens shape design data included in the work data with the actual lens shape measurement data linked to the work number when the work data is output. Thereby, the worker does not need to spend time recreating the work data, and the work data can be managed more appropriately.

[0023] Further, for example, the work data management device may be provided with comparing means (for example, a control unit 42) configured to compare the design data of the lens shape obtained by the first obtaining means with the actually measured data of the lens shape obtained by the second obtaining means. This can prevent mixing up of the actual spectacle frame for which the actually measured data of the lens shape is obtained, and enables more appropriate management of work data. In this case, the comparing means may further include determining means for comparing the design data of the lens shape with the actually measured data of the lens shape and determining whether a difference between the design data and the actually measured data is within a predetermined allowable range, and determination result output means for outputting a result of the determination. When it is determined that the difference is out of the predetermined allowable range, a warning may be output.

[0024] Further, the comparing means may display a first lens shape graphic based on the design data of the lens shape and a second lens shape graphic based on the actually measured data of the lens shape on a display in a comparable manner. In this case, an operator may compare the first lens shape graphic and the second lens shape graphic displayed on the display to determine whether the actually measured data is appropriate.

[0025] It should be noted that the present disclosure is not limited to the device described in the present embodiment. For example, a work data management program (software) that performs the functions of the following embodiments is supplied to a system or a device via a network, various storage media, or the like. Then, a control device (for example, a CPU or the like) of the system or the device can read and execute the program.

[0026] [Example] An example of the present embodiment will be described with reference to the drawings. FIG. 1 is a diagram showing a configuration of a communication processing system 1 for spectacle lenses. In the communication processing system 1 for spectacle lenses according to the example, data related to peripheral edging of a spectacle lens is communicated between an eyeglass store 10 and a lab 20.

[0027] <Eyeglass Store> In Figure 1, the eyeglass store 10 is equipped with an ordering terminal 12 for ordering eyeglass lenses (hereinafter referred to as lens LE). An eyeglass frame shape measuring device (so-called tracer) 14 is connected to the ordering terminal 12 via data communication. The eyeglass frame shape measuring device 14 is configured to measure the contour shape of the rim of the eyeglass frame. For example, the eyeglass frame shape measuring device 14 includes a measuring probe that is inserted into a groove in the rim of the eyeglass frame held by a frame holding part, a moving part that moves the measuring probe along the rim groove, and a detection part that detects the position of the measuring probe moved by the moving part. Based on the detection result of the detection part, the three-dimensional contour shape of the rim is measured. The lens shape (the two-dimensional shape that serves as the processing target for lens LE) is obtained from the measurement result of the rim contour shape. The configuration of the eyeglass frame shape measuring device 14 can be, for example, the technology described in Japanese Patent Application Publication No. 2011-122898.

[0028] In eyewear store 10, if the lens LE selected by the optician is not in stock, an order for the lens LE is placed with the lens manufacturer. For example, the lens order data includes the lens power (spherical power, astigmatism power, astigmatism axis angle, etc.) based on the optician's eye examination data, the material of the lens LE, etc. Furthermore, the lens order data may also include the type of coating of the lens LE, the color data of the lens LE, etc.

[0029] Furthermore, if the eyeglass store 10 does not have the lens LE selected by the eyeglass wearer in stock, and the lens LE is ordered including edge processing, the lab (a lens processing center that centrally processes the edges of many eyeglass lenses) 20 is used. In this case, the lens order data, along with the lens processing order data, is transmitted from the order terminal 12 to the lab 20 via a communication line such as the internet. The lens processing order data includes, for example, processing setting data (also called processing condition data) necessary for lens edge processing. If the eyeglass store 10 has the actual eyeglass frame FL selected by the eyeglass wearer, the rim of the eyeglass frame FL is measured by the eyeglass frame shape measuring device 14, and the lens shape data obtained based on the measurement results is included in the lens processing order data and transmitted to the lab 20 along with the lens order data. For example, the processing setting data includes layout data for the lens shape (data on the positional relationship of the optical center of the eyeglass lens to the lens shape). The processing setting data is set by the workers at the eyeglass store. The processing setting data can be set by the eyeglass frame shape measuring device 14.

[0030] Furthermore, if the eyeglass store 10 does not have the eyeglass frame FL selected by the eyeglass wearer in stock, the eyeglass frame FL is ordered from the lab 20 along with the lens order. For example, the eyeglass frame FL is identified by an identification number (e.g., model number, catalog item number, etc.), and the identified identification number is included in the lens processing order data and sent together with the lens order data, thereby ordering the eyeglass frame FL.

[0031] <Lab Configuration> In Figure 1, Lab 20 is equipped with a core server 22 as a host computer, a database 24, and an eyeglass lens processing system 30. The core server 22 is configured to receive information regarding lens orders, including lens processing, from the ordering terminal 12 of the eyeglass store 10, and to manage the order data related to the received lens orders (including frame order data). The database 24 is connected to the core server 22. The database 24 stores various lens characteristic information (lens power, lens material, refractive index, etc.) associated with the product numbers of eyeglass lenses ordered from the eyeglass store 10, and various frame characteristic information (lens shape design data, FPD, frame material, rim type, etc.) including lens shape design data associated with the identification number of the eyeglass frame. The core server 22 retrieves and obtains the various data stored in the database 24.

[0032] Furthermore, the core server 22 creates and prints a work order JT related to the preparation of the lens LE and the edge processing work. The work order JT is used as a work instruction sheet for the worker. The work order JT is assigned a work number JN generated by the core server 22, along with a barcode BD corresponding to the work number JN. For example, the work order JT is attached to a tray TR. The left and right lenses LE are placed on the tray TR according to the work order JT. If eyeglass frames FL are ordered together with the lenses LE, the eyeglass frames FL are prepared according to the model number of the eyeglass frames FL listed on the work order JT, and the eyeglass frames FL are placed in the tray TR. The tray TR is transported to each work process (including the lens processing process), where the eyeglass frames FL and lenses LE placed in the tray TR are processed.

[0033] The spectacle lens processing system 30 installed in Lab 20 comprises a work data management device 40, a spectacle frame shape measuring device (so-called tracer) 50, a cup mounting device (so-called blocker) 60, and a spectacle lens processing device 70.

[0034] The work data management device 40 includes a control unit 42, which is an example of a processing means. The control unit 42 stores a work data management program and executes processing according to the work data management program. The work data management device 40 may also include a storage unit 44 for storing data. The core server 22 creates work data JD necessary for peripheral processing (lens shape processing) of lenses LE ordered by eyeglass stores. The work data JD is assigned a work number JN from the work order JT and is transmitted to the work data management device 40, where it is stored in the storage unit 44. The work data JD is created to include lens shape data, which is the target contour shape of the lens LE, layout data, and processing setting data such as processing conditions, as data necessary for peripheral processing of the lens LE. The work data JD is created in a format that can be processed by the control unit 42 of the work data management device 40. The storage unit 44 may also be located outside the work data management device 40 (for example, in the core server 22 or the lab 20). In this case, the control unit 42 can simply read the data from the storage unit 44.

[0035] Furthermore, the control unit 42 may also function as a receiving means for receiving data, a data acquisition means for acquiring data, and an output means for outputting data.

[0036] The work data management device 40 is connected to a spectacle frame shape measuring device 50 equipped with a control unit 52, a cup mounting device 60 equipped with a control unit 62, and a spectacle lens processing device 70 equipped with a control unit 72, enabling data transmission and reception. The spectacle frame shape measuring device 50, the cup mounting device 60, and the spectacle lens processing device 70 are connected to barcode scanners 80A, 80B, and 80C, respectively. The barcode scanners 80A, 80B, and 80C are used to read barcode BD attached to the work sheet JT.

[0037] The eyeglass frame shape measuring device 50 may be a device with a configuration similar to the eyeglass frame shape measuring device 14 installed in the eyeglass store 10. The contour shapes of the left and right rims of the eyeglass frame FL placed in the tray TR are measured by the eyeglass frame shape measuring device 50, and the measured data of the lens shape is acquired by the control unit 52. The acquired measured data of the lens shape is associated with the work number JN of the work slip JT by the barcode scanner 80A reading the barcode BD attached to the work slip JT in the tray TR, and is transmitted to the work data management device 40 by the control unit 52. The measured data of the lens shape associated with the work number JN is then acquired by the control unit 42 of the work data management device 40. The acquired measured data of the lens shape is stored in the storage unit 44.

[0038] The cup mounting device 60 is configured to attach a processing jig cup CU (not shown) to the lens surface of the lens LE. The cup CU is used to hold the lens LE on the lens holding shaft of the spectacle lens processing device 70. For example, the cup CU may be attached to the optical center of the lens LE (hereinafter referred to as the optical center mode) or to the geometric center of the lens shape laid out on the lens LE (hereinafter referred to as the frame center mode). When the frame center mode is set as the processing condition, when the barcode scanner 80B reads the barcode BD attached to the work slip JT, the control unit 62 retrieves the work data JD corresponding to the work number JN of the work slip JT from the work data management device 40. Then, the control unit 62 drives the cup mounting mechanism of the cup mounting device 60 and attaches the cup CU to the geometric center of the lens shape laid out on the lens LE. The configuration of the cup mounting device 60 can, for example, use the technology described in Japanese Patent Application Publication No. 2008-299140.

[0039] The spectacle lens processing apparatus 70 is configured to process (cut or grind) the periphery of a lens LE held on a lens holding shaft using a processing tool. For example, the spectacle lens processing apparatus 70 includes a moving mechanism that three-dimensionally changes the positional relationship between the lens LE held on the lens holding shaft and the processing tool, and the moving mechanism is controlled by a control unit 72 so that the periphery of the lens LE is processed by the processing tool. For example, the processing tool includes a roughing tool and a finishing tool. The finishing tool may also include a beveling tool that forms a bevel on the periphery of the roughly processed lens LE. The configuration of the processing mechanism of the spectacle lens processing apparatus 70 can, for example, utilize the technology described in Japanese Patent Application Publication No. 2016-190287.

[0040] When processing the lens LE placed in tray TR, the barcode scanner 80C reads the barcode BD on the work slip JT, and the control unit 72 retrieves the work data JD corresponding to the work number JN on the work slip JT from the work data management device 40. Then, based on the lens shape data and processing setting data contained in the retrieved work data JD, control data for operating the moving mechanism is acquired, and the drive of the moving mechanism is controlled based on this control data, thereby processing the periphery of the lens LE.

[0041] <Operation> Next, we will explain the operation of the work data management device 40 in the above-described communication processing system 1 for eyeglass lenses. Below, we will explain, based on the operation flow diagram in Figure 2, the case in which the eyeglass store 10 has stock of eyeglass frames FL selected by the eyeglass wearer, and the case in which there is no stock of eyeglass frames FL and the eyeglass frames FL are ordered together with the lenses.

[0042] First, if the eyeglass store 10 does not have the lens LE selected by the eyeglass wearer in stock, the ordering terminal 12 processes the order for the lens LE. The order for the lens LE includes lens characteristic information such as the lens power. If the eyeglass store 10 has the eyeglass frame FL selected by the eyeglass wearer in stock, the eyeglass frame shape measuring device 14 installed in the eyeglass store 10 measures the lens shape (contour shape) of the left and right rims of the eyeglass frame FL. In this case, the lens shape data obtained by the eyeglass frame shape measuring device 14 is input into the ordering terminal 12. The eyeglass frame shape measuring device 14 also sets the layout data and processing setting data (working condition data) necessary for lens processing, and this setting data is input into the ordering terminal 12, thereby ordering lens processing (S1). For example, the layout data includes the wearer's PD (distance between the left and right pupils), FPD (distance between the geometric centers of the left and right rims), and the vertical height of the lens optical center. Furthermore, the processing setting data includes, for example, the lens material, the type of rim on the FL eyeglass frame (metal, acetate, semi-rimless, two-point, etc.), whether or not chamfering is present, whether or not mirror polishing is present, and so on.

[0043] On the other hand, if the eyewear store 10 does not have the eyeglass frame FL selected by the eyeglass wearer in stock, the eyeglass frame FL is ordered together with the lens LE. In this case, as mentioned above, the eyeglass frame FL is identified by its identification number. Even if the eyeglass frame FL is not in stock, the layout data and processing setting data necessary for lens processing are set and imported into the ordering terminal 12, thereby ordering lens processing (S1). In this case, the layout data includes data other than the FPD, such as the PD and the vertical height of the lens optical center. For example, the vertical height data of the lens optical center is set by a certain amount according to the policy of the eyewear store 10 (for example, 2 mm above the frame center). The processing setting data also includes data other than that of the eyeglass frame FL (whether or not chamfering is performed, whether or not mirror polishing is performed, etc.). The FPD of the layout data is obtained by measuring the actual eyeglass frame FL in the lab 20.

[0044] When an order for lens processing is placed from the eyewear store 10, the order data is received by the core server 22 in the lab 20 (S2). In the processing of the core server 22, the subsequent processing differs depending on whether or not the received order data includes lens shape data (S3).

[0045] <If the order data includes ball shape data> If the order data includes lens shape data (YES in S3), the core server 22 creates a work order JT with a work number JN based on the received lens processing order data, and also creates work data JD necessary for peripheral processing (lens shape processing) of the lens LE (S4). In this case, the work data JD includes the lens shape data that was sent together with the lens order. The work data JD is created to include lens shape data, which is the target contour shape of the lens LE, layout data, and setting data such as processing conditions, as data necessary for peripheral processing of the lens LE. The work data JD with the work number JN is sent to the work data management device 40 and stored in the storage unit 44. The work data JD is created in a format that can be processed by the control unit 42 of the work data management device 40.

[0046] When work order JT is printed, the worker prepares the unprocessed left and right lenses LE based on the lens part number and lens characteristic information (lens power, etc.) written on work order JT, and places them in tray TR. At this time, based on the lens shape data (layout data may also be considered), lenses LE of a size that can maintain the lens shape are prepared (S5). For example, if the ordered lens LE has a positive power, if the outer size is large, the lens thickness in the center will be thicker, which is disadvantageous for the optician. In this case, by selecting a lens LE with the smallest possible outer size that can maintain the lens shape data, it is possible to avoid the lens thickness in the center becoming thicker. Therefore, lens shape data is required when preparing lenses.

[0047] The tray TR containing the left and right lenses LE, which does not contain the eyeglass frame FL, is transported to the cup mounting process within the work process, and proceeds to the process of mounting the lenses LE onto the lens surface of the cup CU by the cup mounting device 60 (S6). For example, when the barcode BD of the work slip JT attached to the tray TR is read by the barcode scanner 80B, the control unit 62 outputs a request signal to the work data management device 40 requesting work data JD corresponding to the work number JN to which the barcode BD is attached. When the control unit 42 of the work data management device 40 receives the request signal for work number JN, it retrieves the work data JD corresponding to work number JN from the storage unit 44 and outputs it to the cup mounting device 60. As a result, the work data JD corresponding to work number JN is acquired by the control unit 62 of the cup mounting device 60.

[0048] Once the control unit 62 has acquired the work data JD, the cup mounting device 60 can attach the cup CU to the lens surface of the lens LE. For example, if the cup mounting device 60 is configured to automatically attach the cup CU to the lens surface and the frame center mode is set, the cup CU is attached to the center of the lens shape at an eccentric position relative to the optical center of the lens LE, based on the layout data included in the work data JD. For example, if the cup mounting device 60 is configured as a manual device, the operator checks the mark on the lens LE (the mark is made by a lens meter, not shown in the illustration) and the display of the layout data, and attaches the cup CU to the lens surface by moving the arm on which the cup CU is attached.

[0049] Once the cup mounting process is complete, the tray TR containing the lens LE is transported to the lens processing process within the work process, and proceeds to the peripheral processing process of the lens LE by the spectacle lens processing device 70 (S7). For example, as in the cup mounting process, when the barcode BD of the work slip JT attached to the tray TR is read by the barcode scanner 80C, the control unit 72 of the spectacle lens processing device 70 outputs a request signal to the work data management device 40 requesting work data JD corresponding to the work number JN with barcode BD attached. When the control unit 42 of the work data management device 40 receives the request signal for work number JN, it retrieves the work data JD corresponding to work number JN from the storage unit 44 and outputs it to the spectacle lens processing device 70. As a result, the work data JD corresponding to work number JN is acquired by the control unit 72 of the spectacle lens processing device 70.

[0050] Once the control unit 72 has acquired the work data JD, the spectacle lens processing apparatus 70 performs peripheral processing of the lens LE based on the lens shape data. For example, after the lens LE is held on the lens holding shaft of the spectacle lens processing apparatus 70, the lens shape measuring unit first measures the shape of the lens surface (front and rear lens surface) of the lens LE based on the lens shape data. Once the shape of the lens surface is obtained, the control unit 72 obtains processing control data for peripheral processing of the lens LE based on that shape and the lens shape data. The measurement results of the front and rear lens surface shapes based on the lens shape are used as control data for bevel processing to form a bevel on the periphery of the lens LE. Once the processing control data is obtained, the periphery of the lens LE is processed by a roughing tool based on the roughing control data. Subsequently, the periphery of the lens LE is processed by a finishing tool based on the finishing control data.

[0051] <If the order data does not include ball shape data> If the order data does not include lens shape data (NO in S3), the core server 22 retrieves the lens shape design data corresponding to the identification number (identifier) ​​of the eyeglass frame FL included in the received order data from the database 24 and obtains it (S10).

[0052] Furthermore, the core server 22 creates a work order JT with a work number JN based on the order data from the eyeglass store 10. The core server 22 also creates work data JD necessary for processing the periphery of the lens LE based on the order data (S11). The work data JD created at this time includes lens shape design data obtained from the database 24. The work data JD is created to include lens shape data, which is the target contour shape of the lens LE, layout data, and setting data such as processing conditions, as data necessary for processing the periphery of the lens LE. The work data JD with a work number JN is transmitted to the work data management device 40 and stored in the storage unit 44. The work data JD is created in a format that can be processed by the control unit 42 of the work data management device 40.

[0053] Once the work order JT is printed, the worker prepares the unprocessed left and right lenses LE, just as in S5 above (S12). Here, for the same reasons as in S5 above, lens shape data is required to prepare the lenses LE. The order data from the eyeglass store 10 did not include lens shape data, but the database 24 contains design data for the lens shape of the ordered eyeglass frame FL, so the worker can prepare the appropriate unprocessed left and right lenses LE based on that design data. For example, if the ordered lenses LE have a positive power, the lenses LE will be prepared that are small enough in size to accommodate the lens shape data, and have the smallest possible outer diameter. The prepared lenses LE are placed in the tray TR.

[0054] Furthermore, the worker prepares the eyeglass frame FL according to the model number of the eyeglass frame FL listed on the work sheet JT (S13). The eyeglass frame FL is placed in the tray TR containing the lens LE.

[0055] Next, the tray TR containing the lens LE and eyeglass frame FL is transported to the rim shape measurement process of the eyeglass frame FL before the cup mounting process, where the rim shape of the eyeglass frame FL is measured by the eyeglass frame shape measuring device 50 (S14). For preparing the lens LE, the design data of the lens shape is sufficient. However, for processing the periphery of the lens LE, measured data of the lens shape is required. Even if the rim of the eyeglass frame is made using the lens shape from the design data, there will be some variation. For this reason, if the lens periphery is processed using the lens shape from the design data, the fit into the frame may not be good.

[0056] In the process of measuring the rim shape of the eyeglass frame FL, for example, after the barcode BD of the work sheet JT attached to the tray TR is read by the barcode scanner 80A, the rim shape of the eyeglass frame FL is measured by the eyeglass frame shape measuring device 50. The measured data of the lens shape obtained from this measurement is associated with the work number JN of the work sheet JT by the control unit 52 and output to the work data management device 40. The measured data of the lens shape output from the eyeglass frame shape measuring device 50 is not the design data of the identification number of the eyeglass frame FL, but rather the lens shape data measured from the rim of the actual eyeglass frame FL into which the lens LE is fitted, and may be modified into a format that can be processed in subsequent processes (in this embodiment, at least one of the processes of the work data management device 40, the cup mounting device 60, and the eyeglass lens processing device 70). For example, the measured data output from the eyeglass frame shape measuring device 50 may be converted into a certain format to reduce data size, and the converted data may be restored in a subsequent process.

[0057] The control unit 42 of the work data management device 40 receives the measured ball shape data transmitted from the work data management device 40 along with the work number JN, thereby acquiring the measured ball shape data with the work number JN (S15). The control unit 42 then retrieves the work data JD corresponding to the work number JN attached to the measured ball shape data from the storage unit 44, and overwrites the ball shape design data contained in the work data JD with the measured ball shape data (S16). As a result, the work number JN remains unchanged, while the work data JD corresponding to the work number JN is updated and stored in the storage unit 44. In this case, data other than the ball shape data contained in the work number JN and work data JD is not changed. The overwrite process in S16 can be rephrased as a process of replacing or swapping the ball shape design data with the measured ball shape data.

[0058] After the control unit 42 acquires the measured data of the lens shape, the cup mounting process and lens processing process are carried out in the same manner as in S6 and S7 described above. In this case, the lens shape design data included in the work data JD has been changed to the measured data of the actual eyeglass frame FL placed in the tray TR, so the periphery of the lens LE is processed to better fit the actual eyeglass frame FL.

[0059] Furthermore, the overwriting process of the measured data in S16 may include a case where the measured data of the lens shape is associated with the work number JN, rather than the lens shape design data being deleted from the work data JD. In other words, the overwriting process of the measured data in S16 may include a process in which, when the work data JD is called and output in a subsequent process (the cup mounting process in S6, the lens processing process in S7), the measured data of the lens shape associated with the work number is replaced with the aforementioned lens shape design data contained in the work data JD. For example, when the control unit 42 acquires the measured data of a lens shape with work number JN (S15), it stores the measured data in the storage unit 44, associating it with the work number JN. Then, in the subsequent cup mounting process (S6) and lens processing process (S7), the control unit 42, based on the request signal for work number JN, retrieves the work data JD corresponding to work number JN from the storage unit 44. At the same time, it retrieves the measured lens shape data associated with work number JN from the storage unit 44, replaces the design data of the lens shape contained in the work data JD with the measured lens shape data, and outputs the result. This produces the same result as overwriting the measured data.

[0060] As described above, by overwriting the design data of the spherical shape included in the work data JD with the measured data of the spherical shape (including replacement and swapping processes), the worker does not have to recreate the work data JD, and the work data JD is managed appropriately.

[0061] <Example of transformation> For example, multiple eyeglass frame shape measuring devices 50 may be installed in the lab 20, and a first eyeglass frame shape measuring device 50 used to overwrite the design data of the lens shape with the measured data of the lens shape, and a second eyeglass frame shape measuring device 50 used to create new work data JD instead of overwriting the measured data of the lens shape, may be distinguished in advance. In this case, for example, an identification signal to distinguish between the first eyeglass frame shape measuring device 50 and the second eyeglass frame shape measuring device 50 is transmitted simultaneously when the measured data of the lens shape is transmitted. The control unit 42 of the work data management device 40 identifies whether the measured data of the lens shape has been transmitted from the first eyeglass frame shape measuring device 50 based on the identification signal, and if it is identified that the measured data of the lens shape has been transmitted from the first eyeglass frame shape measuring device 50, it may retrieve the work data JD corresponding to the work number JN attached to the measured data of the lens shape from the storage unit 44 and overwrite the design data of the lens shape contained in the work data JD with the measured data of the lens shape. On the other hand, when the control unit 42 identifies that the measured lens shape data has been transmitted from the second eyeglass frame shape measuring device 50, it waits for input such as processing setting data from the operator, assuming that new work data will be created. As a result, the measured lens shape data obtained by the eyeglass frame shape measuring device 50 is not always used to overwrite the design data of the lens shape, but can also be used to create new work data, allowing for flexible handling of eyeglass frame FLs with various orders.

[0062] Furthermore, for example, the work data management device 40 may be equipped with a comparison means configured to compare the design data and measured data of the lens shape. The comparison means is used to confirm that there is no mistake in the actual eyeglass frame FL prepared in S13. Since the actual eyeglass frame FL is prepared by the worker, human error is possible. For example, the control unit 42 compares the measured data of the lens shape corresponding to work number JN with the design data of the lens shape corresponding to the same work number JN and determines whether the difference is within a predetermined tolerance range. If it is determined that the difference is outside the predetermined tolerance range, the control unit 42 issues a warning via a display or the like, indicating that there is a possibility that the eyeglass frame FL used when the measured data of the lens shape was obtained is different from the design data (work data) of the lens shape for work number JN. This warning prompts the worker to confirm that the actual eyeglass frame FL prepared in S13 is the model number listed on the work sheet JT. This prevents the misidentification of the actual eyeglass frame FL from which the measured data of the lens shape was obtained.

[0063] Alternatively, as a means of comparison, a first lens shape figure based on lens shape design data and a second lens shape figure based on actual lens shape measurement data may be displayed on a display device in a comparable manner. For example, the first lens shape figure and the second lens shape figure are displayed on the same screen of a display device controlled by the control unit 42. In this case, the operator can determine the suitability of the eyeglass frame FL from which the actual lens shape measurement data was obtained by comparing the first and second lens shape figures displayed on the display device.
