Description

The present invention relates to a technique for manufacturing an ophthalmic lens such as a contact lens or an intraocular lens, and in particular, when manufacturing a large number of ophthalmic lenses continuously, each ophthalmic lens is managed with high accuracy and efficiency. The present invention relates to an ophthalmic lens manufacturing system and manufacturing method.

  Ophthalmic lenses such as contact lenses and intraocular lenses are manufactured using predetermined raw material monomers, and various methods for manufacturing such lenses have been proposed. Specifically, a cutting method (also called a lace cut method) for cutting and polishing lens blanks, which are intermediate molded products, and a mold forming method for forming a male die together with a female die injected with raw materials ( Also known is a spin casting method, which is also referred to as a cast molding method), in which a raw material is spread along a mold surface of a mold using centrifugal force. These manufacturing methods are selectively employed depending on the raw material and the required shape and dimensional accuracy of the intraocular lens, and may be employed in combination with each other in some cases.

  By the way, the ophthalmic lens is also a medical device attached to the human eye, and high management is required regarding its optical characteristics, shape dimensions, sterilization state at the time of shipment, and the like. Particularly in recent years, since various types of ophthalmic lenses having different optical characteristics and shapes have been provided so as to meet various demands, quality control at the time of manufacturing ophthalmic lenses, etc. Reliability and accuracy maintenance have been increasingly required.

  However, in the conventional management system for manufacturing the ophthalmic lens, it is still difficult to obtain sufficient reliability and accuracy, and there is a part in which the manufacturing efficiency is sacrificed to ensure the management accuracy.

  That is, as illustrated in FIG. 11, the conventional management system creates an instruction in which design data and the like are written on a piece of paper, and passes this instruction to each manufacturing process together with the ophthalmic lens. The person checks the description. However, in such a conventional management system, there is a problem that a lot of manpower and time are required for creating and managing the instructions, and the work is complicated and troublesome. In particular, as described above, in recent years when many kinds of ophthalmic lenses have been produced little by little, such work has become a heavy burden.

  Further, in order to simplify the work, generally, a plurality of ophthalmic lenses that are continuously manufactured according to the same standard are processed with one instruction. However, this leads to lot processing up to management, and individual data such as inspection results after processing does not remain for each ophthalmic lens, which makes it impossible to individually identify ophthalmic lenses. It was. For this reason, for example, even if it is found that there is a possibility of malfunctioning only for some ophthalmic lenses in a specific processing step, all ophthalmic lenses managed in one order are discarded. It had to be disposed of, and the production efficiency was very poor.

  In recent years, it has also been proposed to provide instructions to the site of each process using a computer network. That is, a network system is constructed in which computers are installed at the site of each process of eye lens processing and inspection, and these computers are connected to a management computer. Through the computer network, the instructions are distributed from the management computer to a computer installed at the site of each process of inspection and processing. At the site of each process, the instruction data can be displayed on the monitor, and complicated handling and management of a piece of paper becomes unnecessary.

  However, even when such instruction distribution using a computer is adopted, there is no real difference from an instruction using a piece of paper, and the same problem is inherent. In other words, it is not possible to individually manage the ophthalmic lenses that are manufactured continuously, and it is merely a one-sided transmission of the instruction data from the management computer to the site of each processing and inspection process. Absent. Therefore, even when some ophthalmic lenses are found to be defective in processing or contaminated with bacteria, all ophthalmic lenses managed in one lot have to be disposed of.

  In addition, a new problem specific to a management system using a computer also occurs. It is an accident of hardware and software failures that are unavoidable in computer systems. If such an accident occurs, it will not be possible to obtain or display the order, and the processing and inspection process will be completely stopped, making the manufacturing process extremely unstable and making it Efficiency may be reduced.

  It is also conceivable to manage production of ophthalmic lenses using a bar code and a bar code reader as described in Japanese Patent Application Laid-Open No. 08-202410. That is, it is conceivable to manage each ophthalmic lens individually by attaching a bar code to a pallet or the like that transports the ophthalmic lens in each process or inspection.

  However, even if the ophthalmic lens can be individually identified with the barcode, the instruction data cannot be displayed with the barcode itself because of the large amount of data. There is no change in what is needed.

  On the other hand, for each ophthalmic lens that can be individually identified, the barcode data for identification is uploaded from the on-site computer of each process to the management computer, and then the data of the corresponding instruction is uploaded. A new process of downloading from the management computer to the on-site computer for each process is required. As described above, for each eye lens, the amount of data transmitted / received by a computer in the field in all processes becomes enormous. Considering the fact that multiple ophthalmic lens production lines are installed side by side, and that many processing and inspection processes are set for each line, delays in data transmission / reception in the network, and management computer It can be easily imagined that overloading is a big problem.

  Moreover, even if the data of each individual ophthalmic lens can be stored in the management computer, it is difficult to predict and avoid the accident of the computer as described above. Therefore, when an accident occurs in the management computer, all information becomes unknown, and processing and inspection must be stopped, and instability of manufacturing work and reduction in manufacturing efficiency are inevitable.

  In addition, at the site of each process, the design data and the inspection data regarding the ophthalmic lens existing at hand cannot be browsed without accessing the management computer one by one. Therefore, compared with the case where the instruction book exists as a piece of paper, the browsing and confirmation becomes troublesome. In particular, when the amount of data communication is large and communication delays occur in the network, a waiting state for data transmission / reception of several tens of seconds or more occurs every time processing or inspection is performed, resulting in a decrease in work efficiency. This could result in a system that is extremely difficult to use.

Japanese Patent Laid-Open No. 08-202410

  Here, the present invention has been made in the background as described above, and the problem to be solved is an instruction book consisting of a piece of paper at the site of processing and inspection processes in an ophthalmic lens production line. A new manufacturing system for an ophthalmic lens that can eliminate the need for complicated operations such as management, and can confirm processing instruction information such as standard values efficiently and accurately, and achieve excellent work efficiency, and It is to provide a manufacturing method.

  Further, the present invention can individually identify ophthalmic lenses in an intermediate processed state or a processed state, and can individually manage the state of processing or inspection based on the individual identification information. It is another object of the present invention to provide a novel manufacturing system and manufacturing method for an industrial lens.

Furthermore, the present invention can comprehensively manage various individual data in the ophthalmic lens using a computer, and even if an accident occurs in the computer, there is an adverse effect on the work at the site of each process. It is also an object of the present invention to provide a novel manufacturing system and manufacturing method for an ophthalmic lens capable of avoiding as much as possible.

  The feature of the present invention relating to the “ophthalmic lens production line” made to solve such a problem is that (a) a system for continuously producing a large number of ophthalmic lenses, (b) A container provided with an accommodating part for individually accommodating the ophthalmic lens in an intermediate processed state or a processed state; (c) a conveying means for conveying the container to a plurality of process regions; and (d) provided in the container. And (e) individual information storage means for storing information as an electric signal so as to be writable / readable, and (e) provided at a plurality of locations on the transport path of the container by the transport means, with respect to the individual information storage means A reader / writer device for writing / reading information; (f) identification information storage means for storing identification information for managing each of the plurality of ophthalmic lenses separately as an electric signal; The ophthalmic label is associated with the identification information. Processing instruction information storage means for storing processing instruction information for each lens as an electric signal so as to be writable / readable; and processing completion information for each ophthalmic lens associated with the identification information can be written / read as an electric signal And (g) accessing the total information storage means to store the identification information storage. Writing / reading the identification information, the processing instruction information, and the processing completion information in the processing unit, the processing instruction information storage unit, and the processing completion information storage unit, and accessing the reader / writer device, An ophthalmic lens manufacturing system includes a management computer that writes / reads the identification information, the processing instruction information, and the processing completion information to / from an individual information storage unit.

  In the ophthalmic lens manufacturing system having the structure according to the present invention, in a container that is sequentially conveyed to a plurality of regions where the ophthalmic lens is processed or inspected, the accommodating portion, and thus the ophthalmic lens accommodated therein, The identification information of the attached individual information storage means can be identified separately. Moreover, in the individual information storage means, processing instruction information such as design values and standard values described in conventional instructions is stored as individual data corresponding to the ophthalmic lenses contained in the container. Yes.

  Therefore, the design values and standard values for the ophthalmic lens can be quickly obtained when necessary by using a reader / writer device installed at an appropriate location such as each process area where the ophthalmic lens is processed or inspected. It becomes possible to do. This eliminates the conventional troublesome work of organizing and managing instructions made of paper pieces, and prevents mistakes in the values of other ophthalmic lenses and loss of instructions.

  Furthermore, design values and standard values can be obtained directly from the individual information storage means attached to the container in each processing and inspection process area without requiring data transmission / reception through a computer network. Therefore, the data transmission / reception amount in the computer network is reduced, and even if an accident occurs in the computer system, the influence on the site is avoided as much as possible. That is, at the site of the process of processing or inspecting the ophthalmic lens, it is possible to continue the operation based on information obtained directly from the individual information storage means attached to the container.

  In addition, the individual information storage means attached to each container stores, for example, processing completion information including the presence / absence of each processing and inspection as information on the results of processing and inspection performed in each process. This processing completion information is directly performed by the reader / writer device at the site of each process for processing and inspection.

  Therefore, even when an accident occurs in the computer system or its network and communication with the management computer becomes impossible, the influence on the site is further advantageously avoided. That is, information on completion or incomplete of each individual processing or inspection for the ophthalmic lens can be stored in the individual information storage means until the accident is resolved. Therefore, after the accident is resolved, the processing computer can check the processing completion information stored in the individual information storage means, so that processing and inspection at the site can be handled without interruption as much as possible. It becomes.

  In the ophthalmic lens manufacturing system of the present invention, various information stored in each individual information storage means is also stored in the general information storage means. Therefore, even if any problem is discovered later, it is possible to efficiently determine the ophthalmic lens that is the target of the problem based on the information stored in the general information storage means. Then, it is possible to accurately select only a specific ophthalmic lens in association with the information stored in the individual information storage means attached to the container, and to perform disposal such as rework, reinspection, or disposal efficiently and accurately. It becomes.

  In the ophthalmic lens manufacturing system according to the present invention, the container for accommodating the ophthalmic lens may be any container that accommodates the ophthalmic lenses individually, that is, the individual ophthalmic lenses can be distinguished from each other. Specifically, for example, a pallet-shaped one provided with a plurality of accommodation locations for individually accommodating a plurality of ophthalmic lenses, in addition to an independent type provided with only one accommodation location for accommodating one ophthalmic lens. There may be.

  In addition, when manufacturing an ophthalmic lens, it is not necessary to use a single container for all the processes when the ophthalmic lens is used for a plurality of processing steps and inspection steps. In the middle of the process, it may be transferred to another container or returned to the original container as necessary. Alternatively, when it is necessary to individually identify and manage the ophthalmic lens only in some specific processes, the container is used for individual identification and management only in such processes, and in other processes, lot units are used. It is also possible to manage the ophthalmic lens.

  In the ophthalmic lens manufacturing system according to the present invention, various conveyors such as a belt conveyor are suitably employed as the conveying means for conveying the container, but it is not particularly limited. For example, only some specific steps are performed. In the case of carrying out in a special space such as a clean room, manual conveyance can be used in combination.

  In the ophthalmic lens manufacturing system according to the present invention, as the individual information storage means, one capable of recording and reading information by an electric signal, more preferably one capable of rewriting a plurality of times is adopted. In the case of using a pallet-shaped container having a plurality of storage units as described above, the individual information storage means can be used as long as it can individually identify each storage unit and store data. There is no need to employ individual information storage means that physically correspond to the storage units one by one independently.

  Further, as such individual information storage means, specifically, a commercially available device called an electronic tag or the like can be adopted, and in particular, a terminal for energizing a read / write electric signal in a contact type. It is desirable to be able to read and write by transmitting and receiving electrical signals in a non-contact manner with electromagnetic waves or the like, rather than those provided. Therefore, a wireless IC tag (including a small one called a wireless IC chip) including an antenna for transmitting and receiving data together with the IC chip is preferably employed. The shape, size, specific structure, etc. are not limited in any way, and a power supply built-in type or one without a power supply may be used.

  Furthermore, the individual information storage means is attached to the container and is transported to each process area together with the container. Specifically, in addition to being impossible to remove in the state of being embedded in the container, it may be detachably attached to the container. If removal is impossible, reliability is improved, but the latter detachable structure may be desirable, for example, when the number of reuses of the container and the individual information storage means is different.

  In the present invention, the reader / writer device for accessing stored information to the individual information storage means may be a portable type or a small handy type in addition to a fixed type. In particular, when a wireless IC tag is adopted as the individual information storage means, in general, an antenna for communication, an antenna means for transmitting and receiving electromagnetic waves carrying information, and an electromagnetic wave that modulates or receives received electromagnetic waves for transmission. A reader / writer device constituted by a system including controller means for demodulating and display means such as a monitor for displaying transmitted information and received information is employed.

  In the present invention, various known electric signal storage media can be adopted as the comprehensive information storage means, and examples thereof include a hard disk, an optical disk, a magneto-optical disk, and various semiconductor storage media. The general information storage means includes an independent arithmetic processing unit, and can transmit and receive information to and from the management computer and a communication unit such as a LAN. A built-in type or an external type directly connected by IDE, USB, IEEE, SCSI, or the like may be used.

  Further, the identification information storage means, the processing instruction information storage means, and the processing completion information storage means in the general information storage means do not need to be physically configured independently as long as they have substantially each function. good.

  In the present invention, the storage information of the identification information storage means includes identification information that can individually identify the container and thus the eye lens one by one. As this identification information, for example, data recorded on a commercially available ID chip or the like can be used. Specifically, data that can be converted into data that can be recognized by humans by reading, such as data that is identified by a combination of a plurality of numbers and symbols, is desirable.

  In the present invention, the storage information of the processing instruction information storage means includes design data and / or standard data that is given in advance as an instruction value in processing and inspection. Specifically, the design radius or design value conventionally given in the instructions, or the rear curvature radius (BC), refractive power (POWER), lens outer diameter dimension (DIA), center thickness dimension (CT), etc. Contains the specific value of.

  In the present invention, the storage information of the processing completion information storage means includes confirmation data written from the outside as a completion signal indicating that processing or inspection has been performed. Specifically, it includes data stored by a signal such as a specific flag indicating that each process or process has been completed.

  Note that the information stored in the processing instruction information storage unit and the processing completion information storage unit is associated with the storage information in the identification information storage unit, whereby each information as described above is distinguished for each individual ophthalmic lens. Will be stored and managed.

  In the present invention, the management computer includes general information storage means and appropriate data transmission / reception means for accessing the reader / writer device. The data transmission / reception means may be, for example, a direct connection such as parallel, serial, USB, IEEE, etc., but preferably a communication device for transmitting / receiving electrical signals composed of a wired or wireless LAN mechanism. Consists of lines.

  Then, the management computer exchanges data between the general information storage means and the individual information storage means. For example, the data read from one storage means can be stored in the other storage means, the data read from both storage means can be compared, or the data input from the outside can be stored in both storage means. It is desirable to be able to do so.

  By the way, in the ophthalmic lens manufacturing system according to the present invention, the individual information storage means is repeatedly used in the continuous manufacture of the large number of ophthalmic lenses, and the individual information storage means is repeatedly used. A configuration in which a usage count storage means for storing the usage count is provided in at least one of the individual information storage means and the general information storage means is preferably employed.

  By adopting such a usage count storage means, the usage count can be accurately managed when an IC chip or the like having a finite usage count is employed. That is, the actual number of times stored in the number-of-uses storage unit is managed by comparison with the limit value of the number of times of use instructed by the manufacturer of the individual information storage unit. Replace the information storage means. Thereby, the malfunction of the individual information storage means can be prevented, and the management reliability can be further improved. In addition, if the management computer is used for comparative inspection to check whether the actual number of uses has reached the limit, the number of uses can be managed efficiently.

  In the ophthalmic lens manufacturing system according to the present invention, the identification information includes manufacturing number data attached to the ophthalmic lens, and the manufacturing number data is stored in the individual information storage means. A configuration regarded as one piece of information is preferably employed.

  By storing such serial number data in the individual information storage means, the serial number data attached to the package etc. of the manufactured ophthalmic lens is passed through a host computer such as a management computer. And can be obtained directly from the individual information storage means. Therefore, the process of printing the serial number data can be performed efficiently and accurately.

  The serial number data is preferably stored in the general information storage means as one piece of ophthalmic lens identification information stored in the individual information storage means. As a result, even if the identification information of the individual information storage means used for processing or inspection of the ophthalmic lens is erased after packaging by ophthalmic lens shipping packaging, it is stored in the general information storage means. Based on the obtained data, the packaged ophthalmic lens can be tracked and managed.

  In the ophthalmic lens manufacturing system according to the present invention, the processing instruction information includes product standard data for the ophthalmic lens, and the product standard data is stored in the individual information storage unit. The structure which is made is adopted suitably.

  By storing such product standard data in the individual information storage means, the standard data stored in the individual information storage means is read at the site of the processing or inspection process, and the processing is performed with the target value as the target value. And inspection. Therefore, it is not necessary to obtain information from the comprehensive information storage means for each processing and inspection process, and the burden of transmission and reception lines is reduced. In addition, even when an accident occurs in a computer system such as a management computer, general information storage means, or a data transmission / reception system, the product standard data stored in the individual information storage means is directly used on site for processing and inspection. It becomes possible to continue the work.

  Further, in the ophthalmic lens manufacturing system according to the present invention, the process completion information indicates that the process in a plurality of processes such as processing, work, and measurement predetermined for the ophthalmic lens has been completed for each process. In addition, the configuration in which the process completion data is included as one of the information stored in the individual information storage unit is preferably employed.

  By storing such process completion data in the individual information storage means, for example, even when an accident occurs in the computer system, the process completion data stored in the individual information storage means is confirmed later by the management computer. Or can be transmitted to and stored in the general information storage means. Therefore, even under the situation of occurrence of such an accident, on-site processing and inspection steps are performed and completed, and further steps can be performed as necessary.

  Further, in the ophthalmic lens manufacturing system according to the present invention, the processing completion information includes, for each process, a time during which the ophthalmic lens has been subjected to processing in a plurality of processes such as predetermined processing, work, and measurement. A configuration in which the process time data shown in FIG. 5 is included and the process time data is one piece of information stored in the individual information storage unit is preferably employed.

  By storing such process completion data in the individual information storage means, for example, even if an accident occurs in the computer system, the process time data stored in the individual information storage means is confirmed later by the management computer. Or can be transmitted to and stored in the general information storage means. Therefore, even if such an accident occurs in the case where there is a limit in the work time from a specific process or from a specific process to another specific process for reasons such as quality control, even if such an accident occurs, The processing and inspection processes can be continued and completed sequentially. Then, after the accident is resolved, it can be determined whether or not the limit value on the working time is satisfied by using the process completion data stored in the individual information storage means. Therefore, it is possible to avoid the occurrence of a large number of defective products resulting from stopping the work in each process when an accident occurs.

  Further, in the ophthalmic lens manufacturing system according to the present invention, the process completion information includes an operator who has performed processes in a plurality of processes such as predetermined processing, work, and measurement on the ophthalmic lens. A configuration is preferably employed in which worker data shown for each is included and the worker data is one of the information stored in the individual information storage means.

  By storing such worker data in the individual information storage means, for example, when a specific worker is suspected of being contaminated with bacteria, or when a particular worker is suspected of having a work mistake, It is possible to efficiently cope with the occurrence of human defects in the lens for use. Moreover, since such worker data is stored in the individual information storage means, for example, even when an accident occurs in the computer system, the worker data stored in the individual information storage means is confirmed later by the management computer. Or can be transmitted to and stored in the general information storage means. Therefore, even in the situation where such an accident occurs, it is possible to continue the operations of each process such as processing and inspection without giving up the monitoring function for each worker.

  Further, in the ophthalmic lens manufacturing system according to the present invention, information on the ophthalmic lens to be processed when the ophthalmic lens is subjected to processing in predetermined processes such as processing, work, and measurement. Is preferably adopted from the individual information storage means by the reader / writer device, and based on the read information, the device used for processing in the process is controlled.

  In this way, by adopting means for controlling the operation of the processing and inspection devices used in the processing and inspection processes according to individual ophthalmic lenses, processing and inspection can be performed according to the shape and characteristics unique to the ophthalmic lenses. The inspection can be performed efficiently. Specifically, for example, in the step of inspecting the focal length of the processed ophthalmic lens, the confirmation working distance range of autofocus in the inspection device is changed according to the design value obtained from the individual information storage means By setting, useless operation time in the inspection apparatus can be omitted. In the cutting process of the lens surface, it is also possible to directly control the relative position between the main spindle of the cutting device and the cutting tool based on the standard value read from the individual information storage means, thereby enabling manual operation. It is also possible to avoid the occurrence of defects due to operation mistakes associated with the intervention.

  Further, in the ophthalmic lens manufacturing system according to the present invention, the information stored in the individual information storage unit includes product standard data of the ophthalmic lens, and the container is transported by the transport unit. The processing in the area includes an inspection processing step for inspecting the ophthalmic lens. In this inspection processing step, the product standard data of the ophthalmic lens to be processed is transferred from the individual information storage means to the reader / writer. Read by the apparatus, and compare the read product standard data with the inspection result data obtained in the inspection processing step, to determine the quality determination means for determining the quality of the ophthalmic lens, and the determination result by the non-defective product determination means A configuration including a determination result notifying unit for informing is suitably employed.

  By providing the pass / fail determination means in this way, it is possible to efficiently and accurately determine the pass / fail of the ophthalmic lens based on the inspection result data. It is possible to avoid the occurrence of defects due to.

  The product standard data may be a product design value, or may generally be a product standard value equal to the design value. In the case of a standard value, for example, the refractive power (diopter value) is generally set in a plurality of stages at regular intervals. In that case, as standard product standard data, some standard values may be adopted in addition to a single standard value, and a non-defective product may be determined by matching any one of the standard values. In other words, even when the detected value deviates from one standard value that has been set as a target in advance, a case in which a non-defective product is determined to be usable if it matches another standard that is shifted by one standard is included.

  Further, the quality determination means may be, for example, an arithmetic processing device that compares and calculates product standard data and inspection result data as electrical signals, and an output device that outputs the result. Inspection result data may be output, displayed on a monitor, printed, and artificially determined. The determination result notifying means only needs to display the determination result so that a person can recognize, for example, the monitor means for displaying the product standard data and the inspection result data, respectively, or displaying the pass / fail determination results thereof. In addition, it may be an alarm means for notifying by light or sound when a defect occurs.

  In the ophthalmic lens manufacturing system according to the present invention, the batch process in which the plurality of process regions in which the container is transported by the transporting unit simultaneously processes a plurality of the ophthalmic lenses housed in the plurality of the containers. And a batch processing step including individual information integrated storage means for collectively storing information stored in a plurality of the individual information storage means in a writable / readable manner. Are preferably employed.

  By adopting such individual information integrated storage means, when processing a large number of ophthalmic lenses at the same time, such as heat sterilization processing, the processing efficiency is maintained while maintaining the management accuracy for each ophthalmic lens. Can be performed automatically. That is, an ophthalmic lens is transferred from a small container having one or a small number of accommodating portions to a container having a larger number of accommodating portions, and a large number of ophthalmic lenses are batch processed in this large container. In doing so, the information of all the ophthalmic lenses is transferred from the small-capacity individual information storage means attached to the small container to the large-capacity individual information storage means attached to the large container. Thereby, it becomes possible to selectively use a small number of managements and a large number of simultaneous managements according to the process.

  In addition, for example, when batch processing is finished and is again used for individual processing steps, from a large capacity individual information storage means attached to a large container, a small capacity individual attached to a small container Information of each ophthalmic lens can be transferred to the information storage means.

  In the ophthalmic lens manufacturing system according to the present invention, a configuration including a printing apparatus that prints a product label using information stored in the individual information storage unit is preferably employed.

  By adopting such a printing apparatus, various information associated with each ophthalmic lens by the container can be definitely printed on a label attached to a product package or the like. In addition, since the print information is stored in the individual information storage means, label printing can be performed stably and efficiently without being affected by, for example, an accident of the computer system.

  The information printed on the product label is not particularly limited. For example, in addition to the standard data, measurement data or the like is adopted as necessary. The product label broadly includes a display body that is bonded to or attached to the product package or its package.

  Further, in the ophthalmic lens manufacturing system according to the present invention, a plurality of partial management computers and partial information storage means respectively associated with an appropriate number of the process areas among the plurality of process areas are provided, and associated with each. In the process area, the partial management computer accesses the reader / writer device and the partial information storage means, and the identification information and the processing instruction information for the individual information storage means and the partial information storage means. And a process management information is written / read out, and a comprehensive management computer that comprehensively manages the plurality of partial management computers is provided. The partial management computer and the comprehensive management computer constitute the management computer, A general management computer accesses the individual information storage means and the general information storage means, Configuration in which the identification information and the processing instruction information and the processing completion information to both information storage means so as to write / read is suitably employed.

  As described above, the management computer is composed of a partial management computer and a general management computer and adopts an intermediate storage means, thereby facilitating the response to the accident in the computer system, suppressing the occurrence of damage, and system maintenance workability. It is possible to improve the efficiency. For example, even if an accident occurs in the general management computer, it is possible to prevent data loss by the partial management computer and to continue work in each processing and inspection process by transmitting and receiving necessary information. .

  The ophthalmic lens manufacturing method according to the present invention is characterized in that (h) an ophthalmic lens manufacturing method for continuously manufacturing a large number of ophthalmic lenses, wherein (i) the ophthalmic lens is Provided with individual information storage means for storing individual information as an electric signal in a writable / readable manner as a container for individually accommodating the ophthalmic lens in a plurality of process regions after being individually accommodated in an intermediate processed state or a processed state (J) At a plurality of locations on the transport path of the container, a reader / writer device for writing / reading the individual information to / from the individual information storage means is provided, and (k) Identification information storage means for storing identification information for managing a large number of the ophthalmic lenses separately as an electric signal so as to be writable / readable, and processing instruction information for each ophthalmic lens associated with the identification information as an electric signal Can be written / read as A processing instruction information storage means for storing, and a processing completion information storage for storing the processing completion information for each of the ophthalmic lenses as an electric signal so as to be writable / readable in association with the identification information. (L) accessing the general information storage means and providing the identification information and the processing instruction information to the identification information storage means, the processing instruction information storage means, and the processing completion information storage means. And writing / reading the processing completion information and accessing the reader / writer device to write / read the identification information, the processing instruction information, and the processing completion information to / from the individual information storage means. And (m) storing the ophthalmic lens in the container in which the processing instruction information is written and stored in the individual information storage means and sequentially transporting it to a plurality of the process areas. They In performing a predetermined process on the ophthalmic lens in the process area, the reader / writer device provided in the process area reads and uses the identification information and the process instruction information from the individual information storage unit, and The ophthalmic lens manufacturing method writes the processing completion information in the individual information storage means.

  According to such a method of the present invention, as will be apparent from the description of the ophthalmic lens manufacturing apparatus having the structure according to the present invention described above, it becomes a target in a plurality of process regions for performing processing and inspection. The ophthalmic lens can be confirmed accurately and individually, and various data relating to the ophthalmic lens can be managed efficiently and accurately.

  In addition, even when a trouble occurs in the computer system, the information stored in the individual information storage means reduces or avoids adverse effects on the work of each process for processing and inspecting the ophthalmic lens, and is stable. Work becomes feasible.

  In other words, it is possible to efficiently manufacture individual ophthalmic lenses by using a specific computer system. If any ophthalmic lens is found to be deficient, only the target ophthalmic lens can be accurately identified and reprocessed, re-inspected, disposed of, etc. . Therefore, in the conventional system, since many ophthalmic lenses are managed in units of rods, all of them need to be discarded. In addition, it becomes possible to cope with it efficiently.

  Here, in the method of the present invention, when a failure occurs in access to the general information storage unit, the individual information stored in the individual information storage unit is read and used, and if necessary, new information is stored in the individual information storage unit. By writing such individual information, the processing and inspection processing of the ophthalmic lens is continuously executed, and after the obstacle to access to the general information storage means is resolved, the individual information stored in the individual information storage means is integrated. A mode in which the information storage means is copied and matched is preferably employed.

  By adopting such a mode, for example, even if a trouble occurs in the upper management computer during the operation of the ophthalmic lens manufacturing system and information exchange with the processing site becomes impossible, processing and inspection are performed. By using the individual information storage means transported to the site together with the ophthalmic lens that is the target object, it is possible to continuously carry out processing such as processing and inspection on the ophthalmic lens even during trouble processing It becomes. In addition, since various data obtained during the trouble processing are stored as they are after the trouble is solved, there is no need for a particularly troublesome work such as special data storage processing when the trouble occurs.

Further, in the method of the present invention, the ophthalmic lens manufacturing system of various aspects having the structure according to the present invention described above is preferably used, whereby the method of the present invention can be more advantageously carried out.

  As is apparent from the above description, according to the ophthalmic lens manufacturing system and manufacturing method configured according to the present invention, each ophthalmic lens can be managed with high accuracy and efficiency in the manufacturing process. Is possible.

  Further, in FIG. 1, various known conveying devices such as a belt conveyor, a pallet conveyor, and an air conveyor can be selectively employed as the conveying means 10 between the processes. In addition, when it is difficult to perform continuous conveyance with a conveyance device, such as when a specific process area is an advanced clean room, manual conveyance may be employed as necessary. In FIG. 1, the transfer device and the transfer device are described without distinction.

  Furthermore, the management system shown in FIG. 2 constitutes a comprehensive management system that not only individually manages each hydrous soft contact lens according to the present invention but also comprehensively manages production management and inventory management. . Specifically, such a management system includes, as its hardware, a top-level comprehensive management computer 12, a middle-level management computer 14, and a keyboard 16, a scanner 18, and a monitor 20 as input / output devices for those management computers. , A printer 22 and the like, and a plurality of work management computers 24.

A computer is employed. In particular, in the present embodiment, a data server 25 connected to the computers 12, 14, and 24 by a LAN is provided. The data server 25 is accessible from the general management computer 12, the management computer 14, and the work management computer 24, and has a hard disk as a general information storage means.

  Further, the work management computer 24 is installed at a necessary place among the many work areas shown in FIG. In some work areas, a plurality of work management computers 24 are installed for data storage and management. Further, in these work areas (a plurality of equipment areas 26 and inspection areas 28 shown in FIG. 2 and corresponding to appropriate process areas P1 to 22 in FIG. 1), a leader is provided as necessary. A writer device 30 is installed.

  The reader / writer device 30 can read and write information (read / write) in a non-contact manner using a electromagnetic wave with respect to a predetermined data carry 32 as individual information storage means. Each reader / writer device 30 is connected to a network system including the computers 12, 14, and 24 described above. The reader / writer device 30 specifically uses an IC chip or ID chip or an IC tag or ID tag as a data carry 32 used in an RFID (Radio Frequency Identification) system. Preferably employed. Commercially available products such as V600 series and V700 series manufactured by OMRON Corporation can be used.

  On the other hand, as will be described later, the data carry 32 is attached to each hydrous soft contact lens that is a management target and is sequentially sent to each work area 26 and 28. At this time, in each of the work areas 26 and 28, necessary information can be read and written by accessing the data carry 32 via the reader / writer device 30.

  The reader / writer device 30 may be a handy type or an installation type as appropriate, but generally includes an input unit and a display unit.

Can be confirmed.

  Hereinafter, based on these FIGS. 1-4, the manufacturing process of a hydrous soft contact lens (henceforth "contact lens") is demonstrated one by one.

  Note that the computer network system of the present embodiment constitutes a comprehensive management system that performs production management, inventory management, and the like by operating a plurality of computers 12 and 14 and the like as described above with comprehensive management software. Specifically, such a comprehensive management system is also used in the production management of pharmaceuticals and the like. For example, Hitachi, Ltd. HitFams (registered trademark), Yamatake Corporation (Pharmanage) (registered trademark) and the like, and is constructed using a well-known commercial management software.

  And in this embodiment regarding a contact lens manufacturing system, it implement | achieves using the partial function of these commercially available software for comprehensive management. That is, these comprehensive management software has a function of individually identifying products with identification codes and realizing information management and information storage for each individual product. Therefore, details of specific software contents for realizing information management and information storage for each individual product in the computer system are omitted here.

  When the contact lens manufacturing process shown in FIG. 3 is started, first, a rod-shaped workpiece for obtaining a contact lens is prepared for manufacturing. This rod-shaped processed material is a known material obtained by polymerizing an appropriate crosslinking agent or monomer to a raw material such as PHEMA (polyhydroxyethyl methacrylate) or PVP (polyvinylpyrrolidone).

  In general, a large number of such rod-shaped workpieces are produced under the same composition and the same molding conditions. It is managed separately for each lot, which is the manufacturing unit, and is carried into a lens material receiving process area P1 (see FIG. 1) at the contact lens manufacturing site by the race cutting method.

  The delivered rod-shaped processed material is transported to the humidity control region P2 and supplied to the humidity control storage step S1 (see FIG. 3). This humidity conditioning storage step: S1 is to equalize the moisture content of all rod-like processed materials used in the manufacture of contact lenses. Specifically, for example, by opening a rod-shaped workpiece delivered in a sealed package state and leaving it in a controlled temperature and humidity for a predetermined time, the water content of each rod-shaped workpiece is determined. Align rates. The moisture content varies depending on the contact lens material, but is generally set to a dry state within an appropriate numerical range of less than 10%.

  Then, in the subsequent time judgment step: S2, the humidity control storage step of the rod-shaped workpiece: the humidity control processing time in S1 is checked to see if it has reached a preset required time. Is sent to the next step.

  On the other hand, before the treatment at the humidity control storage step: S1 or after the treatment at the humidity control storage step: S1, an appropriate number of rod-shaped workpieces are extracted and transferred to another measurement region (not shown), Physical property measurement step: provided to S3. In this physical property measuring step: S3, the rod-like processed material is set in the humidity-controlled storage step: S1 and is dried in substantially the same humidity and temperature as the rod-shaped processed material used for the processing described later, or such a rod-shaped processed material. Various physical property values are measured in a swollen state. This physical property value is used for quality determination and the like to be described later. Specifically, the refractive index in a dry state: C1, the linear swelling ratio when the dry state is changed to the swollen state: D, and the swollen state. Refractive index at: C2 and the like.

  The swollen state refers to a state in which the rod-shaped workpiece is completely swollen by containing water until it reaches an equilibrium state (saturated state) in treated water with adjusted osmotic pressure. Further, the linear swelling rate represents a one-dimensional elongation rate when the rod processed material in a dry state becomes swollen due to water content.

  On the other hand, the details of the target contact lens are examined, and a standard value as a design value is determined. In the present embodiment, the standard value is set as a value in the swollen state of the contact lens in consideration of the ISO standard related to the contact lens. Then, when cutting the front surface and the rear surface performed during the following contact lens manufacturing process, the shape to be processed is set based on the standard value determined here. Further, even in inspections and pass / fail judgments appropriately performed during the manufacturing process, it is basically determined whether or not these standard values are met.

  At this time, it is desirable to take into account errors that occur in processing or measurement due to processing errors, aberrations, measurement conditions, and the like. Therefore, in the present embodiment, a correction value for processing in consideration of such an error is also determined in advance according to the target contact lens shape, material, processing conditions, apparatus, etc., and the correction data: B is used as a standard. Along with the value, it is determined in advance.

  Specifically, the correction data: B includes, for example, correction parameters for approximately correcting the value of refractive power: P (diopter) and the value of the vertex curvature of the front surface of the aspheric lens by least square approximation or the like. It is effective to adopt a parameter for correction correction to ISO regulations (contact measurement) when the lens center thickness is measured in a non-contact manner.

  After measuring the physical properties of the lens material (rod-like processed material) and determining the standard value of the target contact lens in this way, the rod-shaped processed material conditioned to a predetermined dry state is used. It takes production.

  For this purpose, first, the rod-shaped processed material that has been conditioned is transported to the lens blank creation step region P3, and the rod-shaped processed material is cut with an appropriate axial thickness dimension to obtain one rod-shaped processed material. A plurality of lens blanks are cut out from. Each of these lens blanks is an intermediate processed product of a contact lens, and is made into a single contact lens as a product by cutting processing described later.

  In addition, the process of obtaining lens blanks from such a rod-shaped workpiece is performed in advance in a place different from the contact lens manufacturing process, and the obtained lens blanks may be carried into the contact lens manufacturing place. good. In that case, lens blanks are received as a lens material in the above-described receiving process region P1 shown in FIG. The lens blanks are carried in a sealed package, and in the next humidity control process area: P2, the humidity is adjusted after opening and adjusted to a predetermined moisture content. Thereafter, the contact lenses are manufactured in the same manner as described above. It will be offered to. When such sealed packaged lens blanks are brought into the contact lens manufacturing site, an appropriate number of lens blanks are sampled and inspected to measure the above various physical properties and various correction data. : B is acquired.

  On the other hand, in a process region: P4 different from the process for preparing the lens blanks as described above, a container for accommodating and transporting the intermediate processed contact lens is prepared. This container may be any container that can stably accommodate a contact lens during transportation by the transportation means 10. In particular, in the present embodiment, as described later, since the contact lens is transported in the treated water in a specific treatment step, a cup-shaped accommodation portion 36 is provided as shown in FIG. 5, for example. Provided as individual containers 38. The individual container 38 accommodates only one contact lens 40 in an intermediate processed state or a processed state.

  Further, in each individual container 38, the above-mentioned data carry 32 is fixed to a thick bottom wall portion in an embedded state. In this data carry 32, an ID code that can individually identify a large number of data carry 32 is stored. If the ID code is not stored in advance, it is written. In addition to the ID code storage area, the data carry 32 includes a rewritable information storage area.

  In a data writing step: S4, data required for contact lens cutting and inspection is written in a rewritable information storage area in the data carry 32. In this embodiment, as the data to be written, in addition to the standard value of the contact lens determined in advance as described above: A (BC, P, DIA, CT), correction data: B, the material property value measured in advance: Includes C and D. Note that these data to be written in the data carry 32 are also transmitted to the general management computer 12 and stored in the data server 25.

  In the data server 25, the information recording medium functions as three storage means, that is, identification information storage means, processing instruction information storage means, and processing completion information storage means. In the functional part as the identification information storage means, the ID codes attached to all the data carriers 32 to be used are stored as identification information, and the values of the past number of uses in the data carry 32 are also stored. Yes. The number of times of use is managed by the general management computer 12 so that it is incremented by 1 every time the data carry 32 is repeatedly used and discarded before exceeding the number of times the data carry 32 can be rewritten.

  In addition, information necessary for execution of cutting and inspection processing is stored as processing instruction information in the functional portion of the information recording medium of the data server 25 as processing instruction information storage means. In the present embodiment, as the processing instruction information, in addition to the standard value and correction data of the target contact lens, material property values are also stored.

  Furthermore, whether or not the functional portion as the processing completion information storage means in the information recording medium of the data server 25 has been completed for each process such as cutting and inspection performed during the manufacturing process of the contact lens. Is stored as processing completion information. The processing completion information may be input manually by a processing completion signal. However, in this embodiment, the reader / writer installed in each of the areas to be processed and inspected in the contact lens manufacturing process: P1 to P22. By using the recognition information of the data carry 32 by the writer device 30, a passage flag is automatically issued as a processing completion signal and stored. This processing completion signal is also written in a rewritable information storage area in each data carry 32.

  Furthermore, the functional part as the processing completion information storage means in the information recording medium of the data server 25 includes an operator who is in charge of the processing for each process such as cutting and inspection performed during the manufacturing process of the contact lens. An operator ID (name, etc.) is also stored so that it can be identified. The worker information is, for example, readers installed in areas P1 to 22 where ID card data given to each worker is processed and inspected in the contact lens manufacturing process every time the worker is changed. The data is read by the writer device 30 and stored in the data server 25. The worker information is also written in a rewritable information storage area in each data carry 32.

  The data stored in the processing instruction information storage unit and the processing completion information storage unit is associated with the ID code of each data carry 32 stored in the identification information storage unit. Thereby, the data server 25 distinguishes the individual contact lenses 40 conveyed by the individual containers 38 to which the respective data carriers 32 are attached, and the processing instruction information and the processing completion information are individually provided for each contact lens 40. In addition to being stored in association with each other, the general management computer 12 or the like can access and write, read, and rewrite information as necessary.

  Thereafter, the intermediate processed product (lens blanks) 40a of the contact lens and the individual container 38 are transferred to an area P5 of the lens accommodation process, and in this area, as indicated by a virtual line in FIG. The intermediate processed product 40a is accommodated in the container.

  Then, the individual container 38 containing the intermediate processed product 40a is transported to the lens rear surface cutting region P6, and the rear surface processing step S5 is performed in this region P6. As the cutting device, a conventionally well-known numerically controlled cutting device as described in, for example, Japanese Patent Application Laid-Open No. 08-252755 can be used.

  Further, the rear surface processing is performed by reading the standard value of the base curve from the data carry 32 by the reader / writer device 30 installed in the cutting region: P6, obtaining the rear surface curvature based on the value, and according to the rear surface curvature. This is done by controlling the operation of the cutting device. In addition, since the back surface curvature is a value in which the standard value (BC) of the base curve is in a swollen state, the back surface curvature at the time of cutting in the intermediate processed product 40a in a dry state in consideration of the linear swelling rate (D). Ask for. The obtained rear surface curvature for cutting is transmitted from the work management computer 24 to the general management computer 12 and stored in the data server 25 as well.

  In this rear surface processing step: processing the intermediate processed product 40a in S5, an intermediate processed product 40b, which is a rear processed lens having a lens rear surface 42 cut with a predetermined curvature as shown in FIG. 6, is obtained. . The obtained intermediate processed product 40b is returned to the individual container 38, and conveyed to the region P7 for measuring the curvature of the rear surface of the lens and determining whether it is acceptable.

  In this region: P7, first, the rear surface curvature measuring step S6 is performed on the intermediate processed product 40b in a dry state. Such measurement of the rear surface curvature can be performed by measuring the curvature E of the optical part on the lens rear surface 42 of the intermediate processed product 40b by using a known optical measuring device called a contact lens analyzer or the like. This type of measuring device is a well-known device disclosed in, for example, Japanese Patent Application Laid-Open No. 04-331345, Japanese Patent Application Laid-Open No. 07-174664, Japanese Patent Application Laid-Open No. 09-229819, and the like.

  In measuring the rear curvature: E, the standard value (BC) of the base curve is read from the data carry 32, and the approximate value of the rear curvature: E is obtained from the value, and the approximate value: a value in the vicinity of E. It is desirable to operate the optical measurement device to search for. As a result, it is possible to perform the measurement operation by narrowing down the measurement width by the optical measuring device from the beginning, and the measurement work can be simplified and the measurement time can be shortened.

  The value of the rear curvature: E thus measured is written in the data carry 32 and transmitted from the work management computer 24 to the general management computer 12 and stored in the data server 25 as well.

  Further, using the obtained rear surface curvature: E value, the rear surface quality determination step: S7 is performed. This pass / fail judgment is performed by comparing the measured value of the rear curvature: E with the standard value: BC read from the data carry 32, and determining whether the standard value: BC is within an allowable range. . Here, since the standard value BC read from the data carry 32 is shown as a value in the swollen state, the linear swelling rate is compared with the rear curvature: E of the intermediate processed product 40b measured in the dry state. : The conversion value calculated using D is adopted.

  Such rear surface pass / fail judgment step: When it is judged as bad in S7, it is judged whether or not an alert is necessary. If the generated error is so large as to be considered as equipment failure, an alarm is issued. , Disposal step: The intermediate processed product 40b is discarded as a defective product in S8. The disposal of the intermediate processed product 40b is transmitted from the work management computer 24 to the general management computer 12 and recorded in the data server 25. The individual container 38 used for transporting the intermediate processed product 40b is collected and reused.

  In addition, an alert monitoring step S9 is used to monitor whether or not an alert is repeatedly issued for a plurality of intermediate processed products 40b that are continuously conveyed with respect to the region of curvature measurement and pass / fail judgment step P7. When an alert issuance is continuously confirmed for a predetermined number or more of the intermediate processed products 40b, a warning is issued or the equipment is stopped to request an equipment check.

  Rear surface quality determination step: When it is confirmed in S7 that the rear surface processing is performed within the allowable error range, the intermediate processed product 40b is conveyed to the jig bonding step region: P8. Then, in the jig bonding step: S10, the lens rear surface 42 of the intermediate processed product 40b is bonded to a predetermined processing jig 44 (see FIG. 7) with an appropriate adhesive 46. Thereafter, the intermediate processed product 40b to which the processing jig 44 is bonded is returned to the individual container 38 and conveyed to the cutting region P9 on the lens front surface.

  Then, in the front surface processing step: S11, the intermediate processed product 40b is subjected to cutting of the lens front surface 48 and the edge portion 50, and as shown in FIG. 7, the contact having the desired optical characteristics is obtained. A lens 40 is obtained. A contact lens cutting method using such a processing jig 44 is well known, for example, as described in Japanese Patent Application Laid-Open No. 07-195556.

  In front surface processing, for example, the value of the front surface curvature obtained by calculation can be applied. That is, the curvature set on the front surface is obtained using values such as base curve: BC (rear surface curvature radius) and power: P (refractive power) described in the processing instruction. Then, the front surface can be cut by controlling the operation of the cutting device in accordance with the obtained front surface curvature. In addition, as a cutting device, the thing similar to the above-mentioned rear surface process can be employ | adopted. Further, the value of the front curvature obtained by the calculation is also stored in the data server 25 through the computer network.

  Subsequently, the obtained contact lens 40 is returned to the individual container 38 and conveyed to a region P10 of the curvature measurement and pass / fail judgment process on the front surface of the lens.

  In this region: P10, first, the curvature of the cut lens front surface 48 is measured. At this time, a known optical measuring device is used in the same manner as the above-described measurement of the curvature of the lens rear surface 42, and this type of measuring device calculates an average curvature of a predetermined irradiation region of the measuring light in the lens. Therefore, the suitability of device use is determined before measurement. That is, in the measurement range determination step: S12, the specifications (Z) of the measuring instrument to be used and the specifications (A, B, C, D) of the contact lens 40 to be measured are taken into consideration for the contact lens 40. Determine if it is appropriate to use a measuring instrument.

This determination is made by, for example, the visual field diameter φDa specified by the following formula under each specific measurement condition, and the optical diameter of the lens front surface 48 processed with a predetermined curvature as an optical part in the contact lens 40 to be measured. It can be done by comparing the entrance pupil: φDb.
Field diameter: φDa = 2 × curvature of lens front surface 48: E × numerical aperture: NA

  That is, when the relationship between the field diameter: φDa and the entrance pupil: φDb is φDa ≦ φDb, the curvature of the front surface 48 of the contact lens 40 can be measured. On the other hand, when φDa> φDb, the front surface 48 of the contact lens 40 includes a peripheral portion that is not an optical portion and becomes a measurement target. Therefore, in this case, assuming that the field diameter is out of the measurement range, measurement is performed by another method (measurement method in a swollen state described later). Therefore, when φDa> φDb, the mark is added to the mark adding step (S17) to be described later without going through the front curvature measurement and pass / fail judgment steps in the following dry state, and the subsequent standard inspection In the step (S26), it is processed by the inspection in the swollen state according to the conventional method.

  And if it is confirmed that φDa ≦ φDb, the front curvature measurement step: S13 is performed. The measurement of the front curvature can be performed using a known optical measurement device called a contact lens analyzer or the like, similarly to the measurement of the rear curvature described above. The measured value F of the front curvature is written in the data carry 32 and transmitted from the work management computer 24 to the general management computer 12 and stored in the data server 25 as well. In addition, since the measured value of the front curvature in the contact lens analyzer is averaged over the irradiation range of the measured light beam, it is desirable to appropriately correct the measured value in the case of an aspheric lens or the like.

  Further, using the value of the obtained front curvature: F, the quality is judged in front quality judgment step: S14. This pass / fail judgment is performed by reading the setting value of the front curvature calculated in the front machining step: S11 from the data carry 32 and comparing it with the measured value of the front curvature: F to determine whether it is within the allowable range.

  Such a front pass / fail judgment step: If it is judged to be bad in S14, it is judged whether or not an alert is necessary, and if the generated error is so large as to be considered as equipment failure, an alarm is issued. , Disposal step: The contact lens 40 is discarded as a defective product in S15. The disposal of the contact lens 40 is transmitted from the work management computer 24 to the general management computer 12 and recorded in the data server 25. The individual container 38 used for transporting the contact lens 40 is collected and reused.

  Moreover, it is monitored by alert monitoring process: S16 whether the alert is repeatedly issued about the some contact lens 40 sent continuously. When alerting is continuously confirmed for a predetermined number or more of contact lenses 40, a warning is issued or the equipment is stopped to request an equipment check.

  Front surface pass / fail determination step: When it is confirmed in S14 that the front surface processing is performed within the allowable error range, the contact lens 40 is conveyed to the mark addition step region: P11. Then, in a mark adding step: S17, a product mark is attached to the peripheral portion of the contact lens 40 using a known laser device or the like. The specific content of the product mark to be attached is set with reference to the standard value read from the data carry 32 or the like. Note that the laser irradiation intensity and time of the laser device are set according to the material of the contact lens 40 and the like, and this set value can also be stored in the data server 25 through a computer network and confirmed later. And

  The contact lens 40 that has been subjected to the cutting process and the mark addition as described above is returned to the individual container 38 and conveyed to the region P12 of the jig removing process. Then, in the jig detaching step: S18, the contact lens 40 is detached from the processing jig 44 to form a single body. The contact lens 40 can be easily detached from the processing jig 44 by a known method as described in, for example, Japanese Patent Application Laid-Open No. 09-90290, that is, by deforming the processing jig 44 made of synthetic resin. Can be done. Alternatively, the contact lens 40 can be detached from the processing jig 44 by immersing it in a liquid to swell the contact lens 40.

  Thereafter, the contact lens 40 as a single unit is returned to the individual container 38 and conveyed to the lens thickness measurement and pass / fail judgment process region: P13, and is supplied to the thickness measurement process: S19. Thickness measurement step: In S19, the lens thickness on the central axis of the contact lens 40 is measured in a dry state. In the present embodiment, this measurement is performed using an optical measuring instrument such as a laser focus displacement meter. Therefore, with respect to the measurement conditions, the correction value obtained by performing correction and converting to the swollen state in order to be consistent with the standard value adopting the value measured using the lightmatic for the swollen contact lens, Thickness measurement: Adopted as G. The lens thickness measurement value G is written in the data carry 32 and is also stored in the data server 25 through the computer network.

  Subsequent thickness quality determination step: In S20, the quality of processing is determined using the measured lens thickness value: G. In this pass / fail judgment, the converted measurement value: G of the lens thickness is compared with the standard value: CT read from the data carry 32, and it is judged whether or not it is within an allowable range. If it is determined that the lens thickness is good or bad in step S20, the contact lens 40 is discarded as a defective product in step S21. The disposal of the contact lens 40 is transmitted from the work management computer 24 to the general management computer 12 and recorded in the data server 25. The individual container 38 used for transporting the contact lens 40 is collected and reused.

  Thickness pass / fail determination step: The power pass / fail determination step: S22 is performed on the contact lens 40 determined to be non-defective in S20. In this pass / fail determination, the power (refractive power) of the obtained contact lens 40 is compared with the standard value P read from the data carry 32 to determine whether it is within an allowable range.

  Here, since the standard value P read from the data carry 32 is shown as a value in the swollen state, an arithmetic value is used as the power of the contact lens 40 in order to determine the power of the contact lens 40 in the dry state. adopt. This calculated value can be calculated by a known optical equation obtained by modifying the Gaussian equation in the power calculation step: S23 using the values of the shape and refractive index of the contact lens 40 actually measured in the above-described steps.

  If it is determined that the power is good or bad in step S22, the contact lens 40 is discarded as a defective product in step S24. The disposal of the contact lens 40 is transmitted from the work management computer 24 to the general management computer 12 and recorded in the data server 25. The individual container 38 used for transporting the contact lens 40 is collected and reused.

  Thickness pass / fail determination step: The contact lens 40 determined to be a non-defective product in S20 is returned to the individual container 38 and conveyed to the lens swelling step region P14. Then, in the immersion step: S25, the contact lens 40 is immersed in a predetermined treatment liquid for a predetermined time to be completely swollen. The treatment liquid to be used is prepared in advance by adjusting the osmotic pressure and temperature according to the material of the contact lens 40 and the like. Further, the processing conditions such as the temperature and the immersion time during the swelling processing are recorded in the data server 25 through a computer network so that they can be confirmed later.

  The fully swollen contact lens 40 is returned to the individual container 38 and conveyed to the lens standard inspection process area P15 which is the next process area. Here, in order to maintain the swollen state of the contact lens 40, as shown in FIG. 8, the storage solution 52 is injected into the accommodating portion 36 of the individual container 38, and the contact lens 40 is immersed therein. To contain.

  In the standard inspection process: S26, the contact lens 40 in the swollen state is measured for necessary values of shape and optical characteristics, and the measured value is compared with the standard value read from the data carry 32 to determine pass / fail. .

  In the present embodiment, the measurement of the back surface curvature, the front surface curvature, and the lens thickness in the dry state performed during the cutting process as described above, and the base curve, the refractive power, and the lens thickness using those measured values are performed. The rejection of defective products is almost achieved by the quality determination. Therefore, the standard inspection of the contact lens 40 in the swollen state in the standard inspection step S26 is not necessarily performed. Specifically, for example, a measurement range discrimination step before measuring the front curvature: measuring the front curvature radius and the refractive power in the swollen state with respect to the contact lens 40 determined that the measurement range in the dry state is not appropriate in S12. The pass / fail judgment is performed.

  Standard inspection process: The measurement result in S26 is transmitted from the work management computer 24 to the general management computer 12, recorded in the data server 25, and written in the data carry 32 as necessary. If it is determined that the standard inspection process is defective in S26, the contact lens 40 is discarded as a defective product in Step S27. Similarly, when the contact lens 40 is discarded, it is recorded in the data server 25 as information. The individual container 38 used for transporting the discarded contact lens 40 is collected and reused.

  After the standard inspection process: S26, the contact lens 40 is returned to the individual container 38 and conveyed to the region of the buff cleaning process: P16. Then, in the buff cleaning step: S28, the contact lens 40 in a swollen state is subjected to buff cleaning to remove cutting flaws and the like. The buff cleaning conditions such as the used cleaning agent and the buff cleaning time are transmitted from the work management computer 24 to the general management computer 12 and recorded in the data server 25.

  The contact lens 40 that has undergone the buff cleaning process: S28 is returned to the individual container 38 and is conveyed to the area P17 of the surface inspection process. Then, in the surface inspection step: S29, the surface state of the swollen contact lens 40 is inspected using a magnifying glass, an optical camera, or the like, and inspected for the presence or absence of damage such as scratches or chips. The inspection conditions, for example, the flowing water speed (pump speed) and the illumination intensity when inspecting in a state immersed in flowing water are transmitted from the work management computer 24 to the general management computer 12 and recorded in the data server 25. To do.

  If it is determined in step S29 that the surface is inferior, the contact lens 40 is discarded as a defective product in step S27. Even when the contact lens 40 is discarded, it is recorded in the data server 25 as information. The individual container 38 used for transporting the discarded contact lens 40 is collected and reused.

  The contact lens 40 that has undergone the surface inspection process: S29 performs a storage process: S30 for storing in a separately prepared packaging case in a storage process area: P18 of the packaging case. This packaging case is a product case, and has a recess 58 for storing the preservative liquid 52 and maintaining the contact lens 40 in an immersed state, as shown in FIGS. Things are adopted. Preferably, a packaging case 60 made of a synthetic resin material that is transparent to such an extent that the presence or absence of the contact lens 40 can be visually recognized from the outside is employed.

  The contact lens 40 is stored in the packaging case 60 by, for example, removing the contact lens 40 from the individual container 38 and performing the surface inspection in the above-described surface inspection step: S29, and then mounting the contact lens 40 on the packaging case 60. It can also be done by putting it directly in In this case, the above-described surface inspection step region P17 and the packaging case storage step region P18 are the same region.

  Further, after the contact lens 40 is accommodated in the recess 58 of the packaging case 60, a cover sheet (not shown) prepared separately is overlapped and covered with the opening of the recess 58. The lid sheet is formed of an aluminum foil sheet or the like that does not transmit the stored liquid, and is closely attached to the opening peripheral edge of the recess 58 of the packaging case 60 by heat sealing or the like. As a result, the recess 58 is tightly covered, and the contact lens 40 is stored in the storage solution 52 in the immersed state.

  When the contact lens 40 is stored, information such as components (bottle, packaging, label, material, etc.), worker, date and time when the contact lens 40 is stored is collected. These pieces of information are recorded in the data server 25 through a computer network.

  Subsequently, the packaging case 60 in which the contact lens 40 is accommodated is conveyed to an area P19 for label printing and pasting. At this time, the data carry 32 in which the information of the contact lens 40 is recorded is also conveyed at the same time. Specifically, in the present embodiment, as shown in FIGS. 9 and 10, an individual tray 62 is employed, and together with the packaging case 60 in which the contact lens 40 is accommodated with respect to the individual tray 62, the previous process. The individual containers 38 used up to are also placed and are transported simultaneously. Thereby, the individual correspondence of the contact lens 40 and the individual information of the data carry 32 is maintained.

  Note that, for example, the packaging case itself is used as a container, the data carrier 32 removed from the individual container 38 is attached, or another data carry 32 is attached to the packaging case, and only the information from the data carrier 32 of the individual container 38 is received. It is also possible to migrate. However, since the data carry 32 can be reused and troublesome and time-consuming work such as information transfer is unnecessary, the packaging case 60 and the individual container 38 are simultaneously transported using the individual tray 62 as described above. Is preferred.

  In the label printing and pasting process area: P19, the label issuing and pasting process: S31 is performed. The label can be issued by reading out information in the data carry 32 by the reader / writer device 30 and printing necessary information. The printed label is affixed to an appropriate location such as the surface of the lid sheet of the packaging case 60, for example. As the label print data, an identification code that is associated with the ID code of the data carry 32 and can specify the recording information of the data server 25 for each contact lens 40 is employed. Specifically, for example, a barcode or a two-dimensional code is attached to the label as an identification code. As a result, even after shipment, the contact lens 40 can be individually identified and the recorded information of the data server 25 can be investigated.

  The contact lens 40 is individually packaged in a sealed state, and the packaging case 60 attached with the product label is then sterilized in an autoclave step: S32. In general, the autoclave is performed in a batch manner by simultaneously putting a large number of packaging cases 60 in one processing chamber. Therefore, in the present embodiment, in order to realize an efficient autoclave, a large container (not shown) capable of simultaneously loading and transporting a large number of packaging cases 60 is separately prepared, and the area of the loading process: At P20, a large number of packaging cases 60 with labels are placed on the large container.

  The packaging case 60 can be replaced by, for example, placing a label on the packaging case 60 and then placing the packaging case 60 directly on the large container without returning to the individual container 38. Can be done. In this case, the above-mentioned label issuance and sticking process area P19 and the large container loading process area P20 are the same area.

  In addition, a large-capacity data carry 64 having a large and robust structure as compared with the individual container 38 is attached to the large container. Specifically, what is called an ID tag or the like and is commercially available and has sufficient heat resistance with respect to the temperature of the autoclave can be used. In this large-capacity data carry 64, all the individual information corresponding to all the packaging cases 60 (contact lenses 40) placed in the large container is obtained from the data carry 32 attached to each individual container 38 or data. Transfer from the server 25 and record. At this time, in order not to confuse information among a large number of packaging cases 60, for example, an identification code associated with the placement position of each packaging case 60 in a large container is assigned to each individual contact lens 40 in the large-capacity data carry 64. Record in association with the record information.

  Thereafter, the large container on which a large number of packaging cases 60 are placed is transported to an autoclave process region P21, and autoclave S32 is performed. At this time, the entire large container on which the packaging case 60 is placed is loaded into the autoclave apparatus for processing, and after the processing, the large number of packaging cases 60 are unloaded for each large container. Thus, autoclaving can be performed while storing individual pieces of information in association with the large-capacity data carry 64 without confusing each other with many packaging cases 60.

  Autoclave: When performing S32, information such as autoclave processing temperature, time, and pressure is collected. These pieces of information are recorded in the data server 25 through a computer network.

  After the processing of the autoclave, all the packaging cases 60 are transported to the final exterior inspection and pass / fail judgment process area: P22. Such a conveyance may be performed while all the packaging cases 60 are placed on a large container. However, in this embodiment, when it is necessary to reprocess as a result of the quality determination, it is essential to individually identify and manage the packaging case 60. Therefore, after taking out from the autoclave device, the large container A large number of packaging cases 60 placed on are returned to the individual tray 62 and conveyed. Used large containers are reused.

  At this time, on each individual tray 62, an individual container 38 having a data carry 32 associated with the packaging case 60 placed thereon is placed. Therefore, as long as the individual tray 62 for returning the packaging case 60 is not mistaken for the other packaging case 60, it is sufficient to write autoclave completion information in the data carry 32 of each individual container 38.

  Then, the packaging case 60 in which the contact lens 40 accommodated as a result of the exterior inspection: S33 and the pass / fail judgment: S34 as a result of the exterior inspection and the pass / fail judgment process area P22 is transported to the stockyard as it is. And stock it for shipping. The determination result of non-defective product is recorded in the data server 25 through a computer network.

  On the other hand, as a result of exterior inspection: S33 and pass / fail judgment: S34, the packaging case 60 in which the accommodated contact lens 40 is determined as a defective product that cannot be repaired is discarded. The disposal of the contact lens 40 is recorded in the data server 25 through the computer network.

  Further, as a result of exterior inspection: S33 and pass / fail judgment: S34, the packaging case 60 in which the accommodated contact lens 40 is determined as a defective product that can be repaired is returned to the individual tray 62 to be in the process area to be repaired. Return it. Then, necessary repairs, rework, reprocessing, or reinspection are performed. At that time, if necessary, the packaging case 60 is opened, and the contact lens 40 is taken out and repaired. After the repair, all the subsequent processing and inspection processes are performed again on the contact lens 40 that has been repaired.

  Note that the individual container 38 and the individual tray 62 used for transporting the packaging case 60 after being finally transported to the stock yard as a non-defective product or discarded as a defective product are collected and reused. To do.

  According to the method for manufacturing a contact lens as described above, a data carry 32 is attached to each processing and inspection area from the state of the lens blank until the contact lens finally becomes a good product or is discarded as a defective product: P5-22 are conveyed. In the data carry 32, various information individually associated with each lens blank is stored, and the information can be used as necessary in each area: P5-22. Also, information can be added as necessary in each area: P5-22. Furthermore, the information written in the data carry 32 is synchronized with the information stored in the data server 25.

  Therefore, the design value or standard value of the ophthalmic lens can be quickly obtained when necessary by the reader / writer device 30 installed at an appropriate place such as each process area for processing and inspecting the ophthalmic lens. It can be obtained. This eliminates the conventional troublesome work of organizing and managing instructions made of paper pieces, and prevents mistakes in the values of other ophthalmic lenses and loss of instructions.

  Furthermore, design values and standard values can be obtained directly from the individual information storage means attached to the container in each processing and inspection process area without requiring data transmission / reception through a computer network. Therefore, the data transmission / reception amount in the computer network is reduced, and even if an accident occurs in the computer system, the influence on the site is avoided as much as possible. That is, at the site of the process of processing or inspecting the ophthalmic lens, it is possible to continue the operation based on information obtained directly from the individual information storage means attached to the container.

  In addition, the individual information storage means attached to each container stores, for example, processing completion information including the presence / absence of each processing and inspection as information on the results of processing and inspection performed in each process. This processing completion information is directly performed by the reader / writer device 30 at the site of each process for processing and inspection.

  Therefore, even if an accident occurs in the work management computer 24 or the general management computer 12, information such as standard values required at each processing and inspection site is obtained from the data carry 32 attached to the contact lens 40. It can be read and obtained directly. In addition, a record of processing time and processing completion required at each processing and inspection site, and storage of inspection results required at each inspection site are also written in the data carry 32 attached to the contact lens 40. And can be synchronized with the data server 25 after recovery.

  Therefore, even if an accident occurs in the work management computer 24 or the general management computer 12, it is possible to suppress the work on site such as each processing and inspection as much as possible, and efficient and smooth work is stable. Can be realized.

  In particular, in the present embodiment, since the inspection after processing is basically performed in a dry state of the contact lens, there are many opportunities to refer to information such as the standard value and the linear swelling rate during the inspection. Therefore, by adopting the data carry 32 or the like as described above, necessary information can be obtained promptly and easily, and planned production can be stably performed.

  In the present embodiment, the data carry 32, the individual container 38, the large container and the like are repeatedly reused, so that there is also a resource saving effect. The information stored in the data carry 32 is rewritten by reuse, but in the present embodiment, various information is stored and accumulated for each contact lens in the data server 25. Even when this problem is discovered, it is possible to efficiently determine the ophthalmic lens that is the subject of the problem.

  Furthermore, in the present embodiment, when changing the instruction, it is not necessary to perform complicated operations such as adjusting the equipment by referring to the instruction made of a piece of paper as in the prior art, so that the production type can be easily switched. And it becomes possible to carry out reliably. Therefore, it is possible to carry out various production activities from high-mix low-volume production to low-mix high-volume production, and it is also possible to easily carry out alternate transition from multi-product low-volume production to low-mix high-volume production, which was difficult in the past. It becomes possible.

  Therefore, it is possible to manufacture according to the lifestyle of the product by freely switching the production as required, and it is also possible to cope with multi-product logistics at the same time.

  In addition, the contact lens manufacturing process is not limited to the cutting process described here, but may be performed by various processing methods such as cutting and polishing process, single-sided molding process, single-sided cutting process, double-sided mold process, It is possible to apply the above system and manufacturing method.
