Method for manufacturing glass plate, original plate process device, processing process device, glass plate manufacturing system, and information processing program

Technical Field

The present invention relates to a method for producing a glass sheet.

Background

In general, in the production of glass sheets, it is required to produce products having a flat surface with less irregularities such as flaws, foreign matter, undulations, and the like. In particular, reduction of irregularities is important in the manufacture of glass substrates for flat panel displays. The various glass sheets shown above are often produced by molding molten glass melted in a melting furnace into a ribbon-shaped glass ribbon, cooling the glass ribbon sufficiently, and cutting the glass ribbon into predetermined dimensions. Here, in the forming of the glass ribbon, a downdraw method such as an overflow downdraw method (fusion method) or a hole downdraw method is generally used in addition to float forming.

Then, after the above-described process, a glass raw plate molded from a glass ribbon (including a large-sized glass substrate for large display, a mother glass substrate in which a small glass substrate is multi-chamfered, and the like) is sent to an inspection step for inspecting characteristics of the glass raw plate such as irregularities on the surface by an inspection apparatus disclosed in patent document 1, for example. The glass raw sheet after the inspection step is sent to the packaging step. In the packaging step, for example, as disclosed in patent document 2, a plurality of glass raw plates and protective sheets are alternately stacked and placed on a tray, thereby forming a package. The package body composed of the tray and the plurality of glass raw plates is transported to a processing factory where the glass raw plates are processed.

Detailed Description

[ embodiment 1 ]

Glass sheet manufacturing system

An embodiment of the present invention will be described in detail below. Fig. 1 is a schematic view of a glass sheet manufacturing system according to an embodiment of the present invention. The glass sheet manufacturing system 100 is a system for manufacturing glass sheets by processing raw glass sheets. The method for manufacturing a glass sheet implemented in the glass sheet manufacturing system 100 is roughly divided into a raw sheet process and a working process. In the original plate process, a plurality of glass original plates are manufactured, and the manufactured glass original plates are loaded on a tray and shipped. The original plate process may be performed in a glass original plate manufacturing factory, for example. In the processing step, the glass raw plates loaded on the tray are taken out and processed, respectively, to manufacture glass plates. The processing step may be performed in a glass plate manufacturing factory, for example. There is no particular limitation on the site of the glass raw sheet manufacturing plant. As an example, the glass raw plate manufacturing factory may be located in a first country, and the glass raw plate manufacturing factory may be located in a second country different from the first country.

(each apparatus for original plate Process)

The glass sheet manufacturing system 100 includes, for example, a master processing apparatus 10, a master manufacturing apparatus 11, an inspection apparatus 12, and a loader 13 as equipment for carrying out a master process. In the present embodiment, the original plate processing apparatus 10, which is an example of a link server, and the inspection apparatus 12 and the loader 13 are connected by wire or wirelessly so as to be communicable via a communication network, not shown. The communication network (not shown) may be, for example, a LAN (Local Area Network: local area network).

The raw plate manufacturing apparatus 11 is an apparatus for manufacturing a glass raw plate from molten glass, and performs, for example, a molding step, a slow cooling step, and a plate collecting step in the raw plate step. The original plate manufacturing apparatus 11 includes, for example, a forming furnace 111, a slow cooling furnace 112, a cooling chamber 113, and a cutting chamber 114. The raw plate manufacturing apparatus 11 shown in fig. 1 is an apparatus for forming a glass raw plate by a down-draw method, but the forming method of the glass raw plate is not particularly limited. For example, a float method of forming a glass raw sheet in a float bath may also be used. With the original plate manufacturing apparatus 11, for example, electronic apparatuses such as a glass substrate for a flat panel display, a glass substrate for a wafer support, and a glass substrate for a cover glass of a solid-state imaging device, and glass products used in image apparatuses can be manufactured.

The forming furnace 111 forms the supplied molten glass into a ribbon shape. The glass molded into a ribbon shape by the molding furnace 111 is conveyed to a slow cooling furnace 112 located vertically below the molding furnace 111. Hereinafter, the glass from the time of molding into a ribbon shape in the molding furnace 111 until cutting is referred to as ribbon glass G1. The slow cooling furnace 112 slowly cools the ribbon glass G1 in the forming furnace 111. A plurality of rollers 221 are provided in the slow cooling furnace 112.

The rollers 221 are arranged in pairs so as to sandwich the ribbon glass G1. In the example of fig. 1, four pairs of rollers 221 are arranged along the conveyance direction (+y direction) of the ribbon glass G1. In fig. 1, only the front roller 221 of the glass ribbon G1 is shown, and the rear roller is not shown. The rollers 221 hold the ribbon glass G1, and convey the ribbon glass G1 in the vertical downward direction (+y-axis direction) without shrinking the ribbon glass G1 in the width direction (±x-axis direction) by surface tension or the like. Although not shown in fig. 1, the slow cooling furnace 112 is provided with a heater, and is configured to slowly cool the ribbon glass G1 while heating the ribbon glass G with the heater.

The ribbon glass G1 gradually cooled by the slow cooling furnace 112 is conveyed to the cooling chamber 113 and cooled to a predetermined temperature range. Then, the ribbon glass G1 cooled to a predetermined temperature range is conveyed to the cutting chamber 114, cut to a predetermined size, and extracted as a plate-like glass. Hereinafter, glass which is drawn into a predetermined size is referred to as a glass raw sheet G.

The inspection device 12 is a device for inspecting the quality of each of the glass raw plates G, and performs an inspection step in the raw plate step. The inspection device 12 may be, for example, a projection inspection device for confirming the presence or absence of irregularities on the surface of the glass raw plate G and for confirming the position of the detected irregularities. In the present embodiment, the inspection device 12 performs an inspection process, and generates original plate data related to processing of each glass original plate G. The original plate data may be, for example, inspection result data indicating the result of the protrusion inspection. The inspection result data includes, for example, determination information indicating the presence or absence of irregularities on the glass raw sheet G to be inspected, and positional information indicating the positions of the irregularities on the glass raw sheet G when the irregularities are detected. In the present embodiment, the inspection apparatus 12 correlates original plate data generated for each glass original plate G, that is, inspection result data, with a glass number uniquely assigned to the glass original plate G, and transmits the correlated original plate data to the original plate process apparatus 10.

In another example, the inspection device 12 may generate, as the original plate data, cutting position data indicating a cutting position determined based on the above-described determination information and position information obtained as a result of the inspection. The cutting position data includes, for example, a cutting position at which the glass sheet is cut out so as to avoid the irregularities on the glass sheet G and to reduce waste. The inspection device 12 may send the cutting position data to the original plate processing device 10 in association with the glass number as original plate data. The inspection device 12 may perform a trimming step of cutting off corners of the glass raw sheet G corresponding to the left and right ends of the strip glass G1, as needed.

The loader 13 is a device for loading the glass raw sheet G onto the tray 14 on which the plurality of glass raw sheets G are loaded, and performs a loading step among the raw sheet steps. The loader 13 may perform a trimming step of cutting off corners of the glass raw plate G corresponding to the left and right ends of the strip glass G1, as needed.

The loader 13 loads the glass raw plate G carried out from the inspection device 12 onto the tray 14. In the present embodiment, it is assumed that each glass original plate G is loaded on a tray 14 by a loader 13 in the order of inspection by the inspection device 12. For example, the glass raw sheet G is inspected by the inspection device 12 and carried out in the order of being picked up by the raw sheet manufacturing apparatus 11, and then loaded on the tray 14 by the loader 13.

The loader 13 may be configured so that the glass raw plates G of the upper limit number of loads (hereinafter referred to as the full number) preset for the trays 14 are required to be loaded on one tray 14. For example, the loader 13 may be configured to always load 100 glass raw sheets G on one tray 14.

The tray 14 and the full-number glass raw plate group Gs loaded on the tray 14 are packaged and shipped as one package in the packaging and shipment process. In the present embodiment, an information recording medium 15 is packaged in one package, and the information recording medium 15 holds an information code for reading out information on the glass original plate group Gs loaded on the tray 14. The package with the information recording medium 15 packaged therein is transported to a glass plate manufacturing factory that performs the processing step. Multiple trays 14 may be transported from one glass sheet manufacturing plant to one glass sheet manufacturing plant. The information code is output to the information recording medium 15 for each of the trays 14 to be shipped by the original plate processing apparatus 10. The information code output to the information recording medium 15 and the information related to the glass original plate group Gs that can be obtained by the information code will be described later in detail. Further, the tray 14 and the glass raw plate group Gs, which are not shown, may be covered with a bag, and transported to a glass plate manufacturing factory.

The original plate process apparatus 10 is an information processing apparatus that controls an original plate process of loading a plurality of glass original plates on a tray. Specifically, the original plate processing apparatus 10 manages information related to the glass original plate group Gs loaded on the tray 14. The original plate processing apparatus 10 may be, for example, a data link server. However, the original plate processing apparatus 10 is not limited to this example, as long as it can perform various information processing to be described later, which the original plate processing apparatus 10 bears. The original plate process apparatus 10 may be, for example, a PC (Personal Co mputer ), a tablet terminal, or the like.

Information on the glass raw sheet group Gs processed by the raw sheet processing apparatus 10 is accumulated for each tray and referred to as a raw sheet management database (hereinafter referred to as a raw sheet management DB) in the glass sheet manufacturing system 100. The master management DB may be stored in a storage unit (storage device, master process storage device) that is locally held in the master process device 10, or may be stored in an external storage device 30 (storage device) such as a cloud service shared by the master process device 10 and the processing process device 20 described later. The master management DB may be transmitted from the master processing apparatus 10 to the processing apparatus 20 via a wide area network NW such as the internet, and stored in a storage unit (storage device, processing storage device) that is locally held in the processing apparatus 20. Hereinafter, as a storage device for storing the original plate management DB, the storage device is collectively referred to as a storage device without distinguishing between the storage portion of the original plate process device 10, the storage device 30, and the storage portion of the working process device 20.

(respective facilities for working procedures)

The glass sheet manufacturing system 100 includes, for example, a processing device 20, a reader 21, and a processor 22 as equipment for carrying out processing. In the present embodiment, the processing device 20, the reader 21, and the processing machine 22, which are servers, are communicably connected by wire or wireless, for example. The communication may be performed via a communication network (not shown) such as LAN (Local Area Network), or via a short-range wireless communication unit.

The reader 21 is a device for reading an information code from the information recording medium 15 packed with the package. The reader 21 can be appropriately configured in accordance with the manner in which the information recording medium 15 holds the information code. For example, when the information recording medium 15 is a printing paper and the information code is a bar code or a two-dimensional code printed on the printing paper, the reader 21 is configured as a bar code reader or a two-dimensional code reader. In the case where the information recording medium 15 is an electronic tag called an RF tag, an IC tag, or the like, the reader 21 is configured as an electronic tag reader that reads an information code embedded in the electronic tag. The reader 21 transmits the information code read from the information recording medium 15 to the machining process device 20. The reader 21 may be a dedicated device for reading information codes, or may be a mobile communication terminal having a plurality of functions, such as a smart phone.

The processing device 20 is an information processing device that controls a processing step of taking out and processing the glass raw plates G loaded on the tray 14, respectively. Specifically, the processing device 20 acquires information about the glass raw plate group Gs loaded on the tray 14, which is necessary for processing the glass raw plate G, and supplies the information to the processing machine 22. The processing device 20 may be, for example, a server. However, the processing device 20 is not limited to this example, as long as it can perform various kinds of information processing to be described later, which are carried out by the processing device 20. The processing device 20 may be, for example, PC (Personal Computer) or a tablet terminal.

The processing device 20 acquires information on the glass original plate group Gs loaded on the tray 14 from the original plate management DB based on the information code acquired via the reader 21. The information code includes information for specifying information on the glass original plate group Gs loaded on the tray 14, among the information on the glass original plate group Gs included in the original plate management DB. The information on the glass raw sheet group Gs may include, for example, raw sheet data of each glass raw sheet G described above.

The processing machine 22 is a device that takes out the glass raw sheet G one by one from the tray 14 and processes the glass raw sheet G. The processing machine 22 includes, for example, a cutter for cutting glass of a predetermined size from a predetermined position of the glass raw plate G to manufacture a glass plate as a product. The processing machine 22 receives information on the glass raw plate group Gs loaded on the tray 14 from the processing device 20, and processes each glass raw plate G according to the information. For example, the processing machine 22 cuts the glass raw sheet G according to the raw sheet data of the glass raw sheet G to manufacture a glass sheet.

Structure of original plate working procedure device

Fig. 2 is a block diagram showing the main part configuration of the original plate processing apparatus 10 according to one embodiment of the present invention. As an example, the master processing apparatus 10 includes a control unit 50, a storage unit 51, a communication unit 52, and an output unit 53.

The control unit 50 controls the respective units of the original plate processing apparatus 10 in a unified manner. The control unit 50 may be constituted by a control device such as CPU (central processing unit) or a dedicated processor, for example.

As an example, the control unit 50 includes a data management unit 71 and an output control unit 72. Each of these control units 50 can be realized by a control device such as a CPU, by reading out and executing a program stored in a storage device (for example, the storage unit 51) realized by ROM (read only memor y), or the like, to RAM (random acces s memory), or the like.

The storage unit 51 (storage device, original plate process storage device) is a storage device for storing data used by the control unit 50 for processing information and data processed by the control unit 50. As an example, the storage unit 51 may store the original plate management DB. Hereinafter, the original management DB is referred to as an original management DB511. The data structure of the original plate management DB511 will be described in detail later. In the present embodiment, the loading interrupt information 512 may be omitted from the storage unit 51.

The communication unit 52 communicates with other devices via a communication network. For example, the communication unit 52 may communicate with the inspection device 12 and the loader 13 via a communication network in a factory such as a LAN. For example, the communication unit 52 accesses the storage device 30 or communicates with the processing device 20 via a wide area communication network NW such as the internet.

The output unit 53 outputs the data processed by the control unit 50 to the outside. In the present embodiment, in particular, the output unit 53 outputs the information code generated by the control unit 50 to the information recording medium 15. The output unit 53 can be appropriately configured according to the manner in which the information recording medium 15 holds the information code. For example, when the information recording medium 15 is a printing sheet, the output unit 53 is configured as a printing device for printing an information code such as a bar code or a two-dimensional code on the printing sheet. In the case where the information recording medium 15 is an electronic tag, the output unit 53 is configured as an electronic tag writer that writes an information code to the electronic tag.

The data management unit 71 manages the master management DB511, and particularly, performs a process of registering master data of the glass master G in the master management DB 511. Specifically, the data management unit 71 associates each original plate data on the glass original plates G loaded on the tray 14 with the loading order of the glass original plates G on the tray 14. The data management unit 71 performs processing for associating a representative glass number (representative original plate identification information) for identifying a representative glass original plate positioned in a predetermined loading order in the tray 14 with original plate data of the representative glass original plate and storing the information in the storage device. Specifically, the data management unit 71 registers the original plate data representing the glass original plate in the original plate management DB511 stored in at least one of the storage unit 51, the storage device 30, and the storage unit 61 of the processing device 20 described later, together with the representing glass number. The data management unit 71 may perform the above-described process of storing the original plate data representing the original glass plate in the storage device together with the representative glass number for each of the trays 14 for shipment. h is a

The output control section 72 executes processing of outputting the representative glass number to the information recording medium 15. For example, the output control unit 72 outputs an information code representing a glass number, which is included in the tray 14 in a predetermined loading order, to the information recording medium 15. The output control unit 72 may execute the above-described process of outputting the representative glass number to the information recording medium 15 for each of the trays 14 for shipment.

The data management unit 71 may determine the final glass original plate finally loaded on the tray 14 as the representative glass original plate. That is, the representative glass original plate may be the final glass original plate in which the loading order in the tray 14 is the final (for example, the 100 th).

In another example, the data management unit 71 may determine the glass raw plate G that is first loaded on the tray 14, that is, the first loading order, as the representative glass raw plate. In another example, the data management unit 71 may determine the glass raw sheet G at any position (for example, 50 th or the like) between the first and final loading steps as a representative glass raw sheet.

As an example, the inspection device 12 inspects 100 glass raw plates G loaded on one tray 14, and generates 100 raw plate data. The inspection device 12 performs inspection in the order of manufacturing the glass raw sheet G by the raw sheet manufacturing apparatus 11, for example, and transmits 100 pieces of raw sheet data of 100 tensors to the raw sheet processing device 10. The inspection device 12 may sequentially send one original plate data to the original plate processing device 10 each time the inspection of one glass original plate G is completed. Alternatively, the inspection device 12 may associate glass numbers including information indicating the manufacturing time or manufacturing sequence of each glass raw plate G with each of the 100 raw plate data, and then transmit the 100 raw plate data collectively to the raw plate processing device 10.

In the present embodiment, the glass number is composed of a character string including a number indicating the date of manufacture and a number indicating the time of manufacture in seconds, as an example. For example, the glass sheet G produced at 1.pm, 50 minutes and 1 second on 1.month/15.2021 may be given a glass number of "20210115—135001". The glass number may include a separator between a number indicating the date of manufacture and a number indicating the time of manufacture.

For example, when the communication unit 52 receives notification from the loader 13 that loading of 100 glass raw plates G onto the tray 14 is completed, the data management unit 71 associates the loading order with raw plate data of each glass raw plate G received from the inspection device 12, and registers the same in the raw plate management DB511. As an example, the data management unit 71 associates the order of loading the original plate data with the order of manufacturing the original plate data of 100 tensors or the order of checking the original plate data. Specifically, the data management unit 71 associates the original plate data, which is the first order of loading, with the original plate data, which is associated with the glass number indicating the earliest manufacturing year, month, day, and time, among the 100 original plate data.

The output control unit 72 may control the output unit 53 as a printing device, for example, to print an information code embedded with a representative glass number on the information recording medium 15 as a paper medium. The output unit 53 outputs the information recording medium 15 of the paper medium on which the information code is printed. The information recording medium 15 may be packaged together with the tray 14 on which the representative glass sheet is mounted, and may be collected in one package.

For example, the data management unit 71 registers all of the 100 pieces of original plate data in the original plate management DB511 in association with the loading order. The output control unit 72 reads out the representative glass number of the representative glass original plate associated with a predetermined loading order, for example, "100 th" from the original plate management DB 511. The output control unit 72 prints the two-dimensional code embedded with the read representative glass number on an information recording medium 15 such as paper, and outputs the code. The output information recording medium 15 is added to the tray 14 on which the above-described 100 glass raw plates G are mounted, and the like, and is collected in one package.

According to the above configuration, by reading the information code from the information recording medium packed with the tray, it is possible to obtain the original plate data of all the glass original plates loaded together before unpacking the tray and taking out the glass original plates one by one. Therefore, after unpacking, the troublesome step of reading the glass number of the glass raw plate to acquire raw plate data of the glass raw plate can be omitted every time the glass raw plate is fed into the processing machine 22 one by one.

Fig. 3 is a block diagram showing the configuration of the main part of the processing device 20 according to one embodiment of the present invention. As an example, the machining process device 20 includes a control unit 60, a storage unit 61, a wireless communication unit 62, and a communication unit 63.

The control unit 60 controls the respective units of the machining process device 20 in a unified manner. The control unit 60 may be constituted by a control device such as a CP U or a dedicated processor, for example.

As an example, the control unit 60 includes a read control unit 81 (identification information reading unit) and a data acquisition unit 82. In the present embodiment, the control unit 60 may further include a data output unit 83. In the present embodiment, the process management unit 84 may be omitted from the control unit 60. Each of these control units 60 can be realized by a control device such as a CPU reading out and executing a program stored in a storage device (for example, the storage unit 61) realized by a ROM or the like to a RAM or the like.

The storage unit 61 (storage device, machining process storage device) is a storage device for storing data used by the control unit 60 for processing information and data processed by the control unit 60. As an example, the storage unit 61 may store the original plate management DB. Hereinafter, the original management DB stored in the storage unit 61 is referred to as an original management DB611. Hereinafter, as the master management DB, when it is not necessary to distinguish between the master management DB stored in the storage unit 51, the master management DB stored in the storage unit 61, and the master management DB stored in the storage device 30, they are referred to as the master management DB without reference numerals.

The original plate management DB611 may include all original plate data included in the original plate management DB 511. That is, the original plate management DB611 and the original plate management DB511 may refer to the same original plate management DB. Alternatively, the original plate management DB611 may include original plate data concerning one or more trays 14 that arrive in one conveyance among the original plate data included in the original plate management DB 511. That is, the original plate management DB611 may be a partial set of the original plate management DB 511. The original plate management DB611 basically has the same data structure as the original plate management DB 511. This data structure will be described in detail later. In the present embodiment, the machining interruption information 612 may be omitted from the storage unit 61.

The wireless communication unit 62 performs wireless communication with another device at a short distance from the processing device 20 or with another device via a communication network in the factory. For example, the wireless communication unit 62 may perform wireless communication with the reader 21.

The communication unit 63 communicates with other devices via a communication network. For example, the communication unit 63 may communicate with the processing machine 22 via a communication network in a factory such as a LAN. The communication unit 63 may communicate with the reader 21 via a communication network in the factory instead of the wireless communication unit 62. For example, the communication unit 63 may access the storage device 30 or communicate with the original process device 10 via a wide area communication network NW such as the internet.

The read control section 81 performs a process of reading the representative glass number embedded in the information code from the information recording medium 15. For example, the reading control unit 81 reads, from the information recording medium 15, a representative glass number of a representative glass original plate in a predetermined loading order (for example, the 100 th) among the glass original plates G loaded on the tray 14. Specifically, the reading control unit 81 may acquire the representative glass number read by the reader 21 via the wireless communication unit 62. The reading control unit 81 may perform the above-described process of acquiring the representative glass number from the information recording medium 15 for each information recording medium 15 corresponding to the tray 14.

The data acquisition unit 82 acquires original plate data of each of the glass original plates G loaded on the tray 14 from the storage device storing the original plate management DB. The data acquisition unit 82 can acquire 100 pieces of original plate data stored in the original plate management DB of the storage device and loaded on the tray 14 from which the representative glass number is read. In the original plate management DB, the loading order of the glass original plates G in the tray 14 and the original plate data of the glass original plates G are stored correspondingly. Here, the reading control unit 81 recognizes the representative glass number of the representative glass original plate loaded in the predetermined loading order (100 th). The data acquisition unit 82 performs processing of acquiring a predetermined number of original plate data corresponding to the loading order in succession, starting from original plate data representing the glass original plate identified by the read representative glass number, among the original plate data registered in the original plate management DB. For example, the data acquisition unit 82 acquires continuous original plate data associated with the loading order from the original plate management DB, starting from the original plate data representing the glass original plate associated with the 100 th specified by the representative glass number. That is, the data acquisition unit 82 acquires 100 pieces of original plate data associated with the loading order, which are consecutive from the 100 th original plate management DB. The data acquisition section 82 performs the above-described process of acquiring the original plate data from the original plate management DB in units of a tray for each of the conveyed trays 14.

When the representative glass original plate is the final glass original plate finally loaded on the tray 14, the data acquisition unit 82 acquires, from the storage device, a predetermined number of original plate data associated with the loading sequence in descending order, starting from original plate data of the final glass original plate associated with the representative glass number read from the information recording medium 15. In one specific example, if the final glass original plate loading order is 100 th, the data acquisition unit 82 acquires 100 th original plate data associated with the loading order, namely 100 th, 99 th, 98 th, … st, and 1 st, from the storage device.

According to the above configuration, the original plate data of each glass original plate loaded on the same tray is acquired in a state in which the loading order can be known. In the processing step, the raw plate data of the final glass raw plate is taken out in the order reverse to the loading order when the raw plate data is loaded on the tray, and when the raw plate data is processed in the order of taking out, the processing machine 22 can acquire the raw plate data in the order reverse to the corresponding loading order. In this way, the original plate data is referred to in the processing order, and therefore, the glass original plate and the original plate data can be easily associated.

The control unit 60 may further include a data output unit 83. The data output unit 83 outputs the predetermined number of original plate data acquired by the data acquisition unit 82 to a device for processing a glass original plate, such as the processing machine 22, in a reverse order to the loading order corresponding to each original plate data.

According to the above configuration, in the processing step, the respective glass raw plates loaded on the tray are taken out in the order reverse to the loading order when loaded on the tray, and are preferably used when processing is performed in the order of taking out. According to the above configuration, the original plate data is input to the processing machine 22 in the order reverse to the loading order to the tray, that is, the order in which the glass original plates are put into the processing machine 22. Thus, the processing machine 22 can process each of the glass original plates based on the correct original plate data.

Data structure

(information recording Medium)

Fig. 4 is a diagram showing an example of a data structure of information held by the information recording medium 15 in association with the tray 14. The information recording medium 15 holds at least a representative glass number of a representative glass original plate loaded on the tray 14 in a predetermined loading sequence.

The information recording medium 15 can also hold a factory name as information uniquely identifying a factory that manufactures the glass original plate group Gs loaded on the tray 14, as needed. The information recording medium 15 may hold, for example, a line name as information for uniquely specifying a line for manufacturing the glass sheet group Gs in the factory.

For example, the output unit 53 of the original plate processing apparatus 10 prints information codes, in which the factory name, the line name, and the representative glass number representing the original glass plate are embedded, on the information recording medium 15 associated with the tray 14. The information recording medium 15 printed with the information code is collected together with the tray 14 in one package and delivered.

(original plate management DB)

Fig. 5 is a diagram showing an example of a data structure of the original plate management DB stored in the storage device. In the master management DB, a record is created and registered for one glass master G. The recording group P1 represents information related to one tray, for example, 100 glass original plate groups Gs mounted on the 1 st tray, and the recording group P2 represents information related to the other tray, for example, 100 glass original plate groups Gs mounted on the 2 nd tray.

As an example, each record is composed of a factory name, a line name, a glass number, original plate data, and data items of the loading order. The factory name is information uniquely identifying the factory where the glass raw sheet G is manufactured. The line name is information uniquely identifying the line in which the glass raw sheet G is manufactured in the above-described factory. The glass number is original plate identification information that uniquely identifies the glass original plate G. As described above, as an example, the glass number may be configured to include: a number column indicating the year, month, and day of manufacturing the glass raw sheet G, a number column indicating the time of manufacture in seconds, and a separator dividing between the number columns.

The original plate data is information related to processing of the glass original plate G generated by the inspection device 12. The original plate data is, for example, inspection result data, and may include determination information indicating the presence or absence of irregularities and position information indicating the positions of irregularities. In other examples, the original plate data may be cutting position data for processing the glass original plate G without any waste while avoiding the irregularities.

The loading sequence is information indicating the sequence in which the glass raw plate G is loaded on the tray 14. For example, from the record of the uppermost stage of the original plate management DB shown in fig. 5, it is known that the glass original plate G of the glass number "20210115_135001" is the first, i.e., the first loaded one of the trays 14. As is clear from the record R1, the glass original sheet G of the glass number "20210115_135036" is the 100 th, i.e., last loaded, one of the same trays 14. Further, since the glass raw sheet G of "20210115_135036" is related to the 100 th predetermined loading sequence, it is known that the glass raw sheet G is a representative glass raw sheet of the same tray 14. It is also known that "20210115_135036" is a representative glass number in the tray 14 described above.

The data management unit 71 of the original plate processing apparatus 10 receives the original plate data and the glass number of a predetermined 100 tensor loaded on the same tray 14 from the inspection apparatus 12.

The data management unit 71 associates the loading order in order from the beginning of the manufacturing year, month, day, and time indicated by the glass number, and then registers 100 records, for example, the record group P1 in the original plate management DB as shown in fig. 5. When receiving 100 pieces of original plate data for the other trays 14 from the inspection device 12, the data management unit 71 registers 100 records, for example, the record group P2 in the original plate management DB by the same method.

The data management unit 71 may receive notification from the loader 13 that the loading of the 100 glass raw plate groups Gs onto the tray 14 is completed. The data management unit 71 may start the process of registering the record group of 100 records in the master management DB based on the master data of 100 tensors received from the inspection device 12 and the notification received from the loader 13.

< processing flow >)

Fig. 6 is a sequence diagram showing a process flow of the glass sheet manufacturing method performed by the glass sheet manufacturing system 100. The manufacturing method shown in fig. 6 may be started by, for example, the inspection device 12 generating original plate data, for example, 100 original plate data, of the full-number glass original plates G loaded on one tray, and by the original plate processing device 10 receiving these original plate data as a trigger. The above-described manufacturing method may be started with the trigger of receiving the notification that the full-number glass raw sheet G is completely loaded from the loader 13.

The method for manufacturing a glass sheet performed by the glass sheet manufacturing system 100 generally includes a raw sheet process and a working process.

In the original plate process, the original plate process apparatus 10 performs the steps of: a storage step of associating original plate data related to processing of the glass original plates G with a loading order of the glass original plates G in the tray 14 for each glass original plate G loaded in the tray 14, and performing processing of associating a representative glass number (representative original plate identification information) for identifying a representative glass original plate positioned in a predetermined loading order in the tray 14 with the original plate data of the representative glass original plate for each tray 14 and storing the same in the storage unit 51 (storage device); and an information output step of performing, for each tray 14, a process of outputting the representative glass number to the information recording medium 15.

In the machining process, the machining process device 20 performs the steps of: a reading step of reading a representative glass number from each of the information recording media 15; and an acquisition step of performing processing of acquiring, for each tray 14, a predetermined number of original plate data corresponding to the loading order continuously from the storage device, starting from original plate data representing the glass original plate identified by the read representative glass number, among the original plate data stored in the storage device.

In the processing step, the processing step apparatus 20 may execute a data output step of outputting the predetermined number of original plate data acquired in the acquisition step to the apparatus for processing the glass original plate in an order reverse to the loading order corresponding thereto.

The original plate process includes, for example, steps S101, S102, S104, S107, and S108 shown in fig. 6. Alternatively, the original plate process may include steps S101 to S111, if necessary. The processing step includes, for example, steps S112 to S114 shown in fig. 6.

In step S101, the data management unit 71 of the original plate processing apparatus 10 refers to the original plate data set of 1 tray amount transmitted from the inspection apparatus 12. For example, the data management unit 71 may refer to 100 original plate data of 100 glass original plates G mounted on the 1 st tray. The original plate data set transmitted from the inspection apparatus 12 is stored in advance in a storage unit 51 or a primary storage device, not shown, provided in the original plate process apparatus 10, for example.

In step S102 (storage step), the data management section 71 associates one loading order with one original plate data. For example, the data management unit 71 may establish the corresponding loading order in ascending order in the order in which 100 pieces of original plate data are received. Alternatively, the data management unit 71 may associate the loading order in ascending order from the beginning of the older manufacturing time indicated by the glass number associated with each of the 100 original plate data.

In step S103, the data management unit 71 determines whether or not the loading order associated in step S102 is a predetermined loading order. For example, the data management unit 71 associates the loading order of "100 th" with the original plate data whose manufacturing time is the latest among the 100 original plate data in S102. If the predetermined loading order is "100 th", the data management unit 71 determines yes in S103, and proceeds to S104. If the corresponding loading order is set to be other than the predetermined loading order "100 th" in S102, the data management unit 71 determines no in S103, and the process proceeds to S105.

In step S104 (storage step), the data management unit 71 identifies the glass raw plate G of the predetermined loading order "100 th" as a representative glass raw plate, and associates the representative glass number with the raw plate data of the representative glass raw plate corresponding to the predetermined loading order "100 th". Here, in the case where the original plate data representing the original glass plate referred to in S101 already corresponds to the glass number, the data management unit 71 may process the original glass number obtained in S101 directly as the representative glass number. Alternatively, the data management unit 71 may generate a representative glass number composed of a character string capable of uniquely specifying original plate data representing the glass original plate, and may associate the representative glass number with the original plate data representing the glass original plate.

In step S105, the data management unit 71 determines whether or not the loading order is completed for all the original plate data referred to in S101. For example, if original plate data that does not correspond to the loading order remains in the 100 original plate data referred to in S101, the data management unit 71 proceeds from no in S105 to S106. When associating the loading order of 1 st to 100 th with 100 original plate data, the data management unit 71 proceeds from yes in S105 to S107.

In step S106, the data management unit 71 refers to the next unprocessed original plate data, increments the loading order to be associated with, and returns to step S102, and repeats the subsequent processing.

In step S107 (storage step), the data management unit 71 associates each original plate data with the loading order, and stores at least one tray-amount original plate data group representing the association of the glass number and the original plate data representing the glass original plate in the storage device. For example, the data management unit 71 may register the original plate data set in the original plate management DB 511.

In step S108 (information output step), the output control unit 72 outputs the representative glass number associated with the original plate data of the representative glass original plate in S104 to the information recording medium 15. As an example, the output control unit 72 controls the output unit 53 to print the information code embedded with the representative glass number on the information recording medium 15 as a paper medium. The printed information recording medium 15 is packaged together with the tray 14 (in the above example, the 1 st tray) as one package.

In the present embodiment, the data management unit 71 may repeat the above steps for each tray for a lot Zhang Tuopan shipped in the same glass sheet manufacturing factory, as an example.

In step S109, the data management unit 71 determines whether or not the steps of S102, S104, S107, and S108 are performed for all trays for which shipment is scheduled. If the original plate data set of the other tray remains unprocessed, the data management unit 71 proceeds from no in S109 to S110. When the registration to the original management DB511 and the output of the information recording medium 15 are completed for all the trays, the data management unit 71 proceeds from yes in S109 to S111.

In step S110, the data management unit 71 refers to the original plate data set of the next tray, returns to step S102, and repeats the subsequent processing.

In step S111, the data management unit 71 may notify the processing device 20 that the original plate management DB including information related to processing of the glass original plate G is stored in a storage device readable by the processing device 20. For example, the data management unit 71 may directly transmit the original plate management DB511 stored locally in the storage unit 51 to the processing device 20 via the communication unit 52. Alternatively, the data management unit 71 may upload the original plate management DB511 to the storage device 30 and notify the machining process device 20 of the uploaded result. Alternatively, the data management unit 71 may transmit an access permission notification to the original plate management DB511 stored in the storage unit 51 to the machining process device 20.

In step S112 (reading step), the reading control unit 81 of the processing device 20 reads the representative glass number from the information recording medium 15 corresponding to the target tray (hereinafter referred to as the work target tray) of the glass raw sheet G to be subjected to the processing. Specifically, the reader 21 reads the representative glass number of the representative glass original plate in the start-up object tray from the information code printed on the information recording medium 15 packaged together with the start-up object tray. The reading control section 81 acquires the representative glass number read by the reader 21.

In step S113 (acquisition step), the data acquisition unit 82 acquires, from the storage device, the original plate data set of each glass original plate G loaded on the start-up object tray. As an example, the data acquisition unit 82 may extract 100 original plate data corresponding to 100 glass original plates G loaded on the work object tray from the original plate management DB generated by the original plate process apparatus 10.

Specifically, the data acquisition unit 82 acquires, from the storage device, a predetermined number of original plate data corresponding to the loading sequence, starting from the original plate data representing the glass original plate identified by the representative glass number read in S112, among the original plate data stored in the storage device.

Specific examples are described. Let the representative glass number read by the read control unit 81 be "20210115 _ 135036" in S112. The data acquisition unit 82 determines a record R1 of the representative glass original plate associated with the representative glass number "20210115 _ 135036" from the original plate management DB shown in fig. 5.

The data acquisition unit 82 extracts 100 consecutive records corresponding to the loading order "100 th" from the loading order of the record R1 as the start point from the original plate management DB. Here, the representative glass original plate is the final glass original plate loaded on the tray 14 at the last, i.e., the 100 th. Therefore, the data acquisition unit 82 extracts, from the master management DB, 100 recorded master data groups corresponding to the loading order in descending order, starting from the record R1 of master data that is the final glass master. In the example shown in fig. 5, a record group P1 composed of 100 records corresponding to the loading order (99 th, 98 th, … st, 1 st) continuing in descending order from "100 th" is extracted from the original plate management DB.

In step S114 (data output step), the data output unit 83 outputs the predetermined number of raw plate data acquired in S113 to the apparatus for processing glass raw plates in the order reverse to the corresponding loading order. Specifically, the data output unit 83 outputs 100 records of the record group P1 extracted in S113 to the processing machine 22 in descending order from the record R1 of the "100 th" which is the final loading order. When unpacking the work object tray, the processing machine 22 sequentially takes out the glass raw plates G loaded on the work object tray one by one, and inputs the glass raw plates G into the cutting machine. Since the original plate data of the original glass plate G is input to the cutter in the order in which the original glass plate G is input, the cutting function can cut the original glass plate G based on the correct original plate data corresponding to the original glass plate G.

< Effect >

According to the above configuration and method, in the master process, master data of each glass master loaded on one tray is stored in the storage device in association with the loading sequence to the tray. Here, the original plate data of the representative glass original plate loaded on the tray in a predetermined loading order (for example, the last 100 th), is associated with a representative glass number for identifying the representative glass original plate, and stored in the storage device.

In the processing step, the representative glass number is read from the information recording medium. Then, the original plate data of a predetermined number (for example, 100 pieces in descending order from the predetermined loading order "100 th") associated with the loading order is read from the storage device, starting from the original plate data of the representative glass original plate identified from the representative glass number.

In this way, original plate data of each glass original plate loaded on the same tray including the representative glass original plate is read out together with the loading sequence when the glass original plate is loaded on the tray. Since the loading order is associated with the original plate data, each glass original plate on the tray can be accurately associated with the original plate data based on the loading order in the factory where the processing step is performed. By properly performing the correspondence, the glass raw plate can be properly processed.

According to the above-described configuration and method, it is not necessary to directly add a glass number to each of the glass raw plates loaded on the tray, and it is only necessary to hold the representative glass number on the information recording medium for the representative glass raw plates loaded in a predetermined loading order.

As described above, according to the above-described method for producing a glass sheet, it is possible to easily correlate a glass original sheet with original sheet data.

In the step of directly printing individual identification information such as a two-dimensional code on each glass original plate, it is considered that a large-scale apparatus (a dedicated inkjet printer or the like for printing on a large-sized glass) for printing the two-dimensional code on the glass original plate is required. According to the above-described glass sheet manufacturing method, such a large-scale facility can be omitted, and thus, particularly advantageous effects can be obtained from the viewpoint of labor and cost reduction.

[ embodiment 2 ]

Hereinafter, other embodiments of the present invention will be described. For convenience of explanation, members having the same functions as those described in the above embodiments are given the same reference numerals, and the explanation thereof is not repeated.

In the present embodiment, the loader 13 allows loading of one tray 14 with an insufficient number of sheets (hereinafter, referred to as mantissa) according to the situation. In the present embodiment, in the notification that the loading machine 13 has completed loading onto the tray 14, the number of sheets including the glass raw sheets G loaded on the tray 14 is sent to the raw sheet processing apparatus 10.

In the present embodiment, for example, in step S104 shown in fig. 6, the data management unit 71 of the original plate processing apparatus 10 may store the number of glass original plates G loaded on the tray 14 in the storage device in association with the representative glass number. In another example, in step S108 shown in fig. 6, the output control unit 72 may output the number of glass raw plates G loaded on the tray 14 to the information recording medium 15 together with the representative glass number.

In the present embodiment, in S113 shown in fig. 6, the data acquisition unit 82 of the processing device 20 acquires the same number of original plate data as the number of sheets corresponding to the representative glass number from the storage device.

Specific examples thereof are shown below. The number of sheets corresponding to the representative glass number on which the 80 th representative glass plate was mounted was set to "80". In this case, the data acquisition unit 82 acquires the original plate data of the number of sheets corresponding to the loading sequence, which is continuous in descending order, from the storage device, starting from the original plate data representing the glass original plate. That is, the data acquisition unit 82 acquires 80 pieces of original plate data from the storage device from the "80 th" to the "1 st" in the loading order.

< Effect >

According to the above-described structure and method, even when the number of sheets of glass original sheets to be loaded per tray is different, original sheet data of a plurality of glass original sheets loaded on one tray can be appropriately acquired from the storage device. Therefore, the method for manufacturing a glass plate according to the present invention can be applied to a case where trays having different upper limit numbers are mixed, or a case where trays having full numbers and trays having mantissas are mixed. That is, the glass sheet manufacturing system 100 of the present invention can be applied to all shipment cases.

[ embodiment 3 ]

In the present embodiment, a tray ID for uniquely identifying identification information of each tray is given to each tray 14. In the present embodiment, the tray 14 is provided with an information recording medium 16 (see fig. 1) for holding a tray ID.

In the original process, the loader 13 may be communicably connected to a reader (not shown) for reading the tray ID from the information recording medium 16 provided on the tray 14. For example, the loader 13 can acquire the tray ID of the tray 14 on which the glass original plate G is loaded from the information recording medium 16 via the above-described reader.

< interrupt for load operation >

In the present embodiment, the original plate processing apparatus 10 may use the tray ID to manage progress of the loading operation of the glass original plate G onto the tray 14, as an example.

In the present embodiment, the loading interruption information 512 may be stored in the storage unit 51 of the original plate processing apparatus 10. The loading interruption information 512 is information indicating the progress of the loading operation of the glass raw plate G onto the tray 14 for each tray 14.

Fig. 7 is a diagram showing an example of a data structure of the loading interrupt information 512. For example, the loading interruption information 512 is composed of two data items, that is, a tray ID and the number of sheets to be loaded. In other examples, the load interrupt information 512 may have a status data item, if desired.

The tray ID is identification information that uniquely identifies the tray 14. The number of sheets is information indicating the number of sheets of glass raw sheets G that have been loaded on the tray 14. The number of sheets to be loaded may be expressed, for example, by taking the full number of the tray 14 as a denominator and the number of sheets currently loaded on the tray 14 as a score of a numerator. The status is information indicating progress of the loading operation in the tray 14.

In the present embodiment, before loading of the glass raw sheet G onto the tray 14 is started, the loader 13 acquires the tray ID of the acquisition tray 14 via the above-described reader. The loader 13 transmits the acquired tray ID to the original plate process apparatus 10, and notifies the original plate process apparatus 10 of the start of loading onto the tray 14 corresponding to the tray ID.

The data management unit 71 of the original plate processing apparatus 10 registers the notified tray ID in the loading interruption information 512. The data management unit 71 may register a status of "in-progress" indicating that the current loading job is in progress in association with the tray ID.

When the loading operation is interrupted while the number of glass raw plates G is less than the full number, the loader 13 sends the tray ID of the tray 14 on which the loading is interrupted and the number of sheets already loaded on the tray 14 to the raw plate process apparatus 10, and notifies the raw plate process apparatus 10 of the interruption of the loading operation.

The data management unit 71 may perform the original plate process recording step of storing the tray ID (tray identification information) for identifying the tray 14 in the storage unit 51 in association with the number of sheets (information indicating the number of loads) already loaded on the tray 14 for the tray 14 having the number of sheets (number of loads) less than the full number (upper limit value) of sheets G. The information in which the tray ID and the number of sheets to be loaded are associated with each other is not limited to being stored in the storage unit 51, and may be stored in any storage device such as the storage device 30 to which the original sheet processing apparatus 10 can refer.

According to the above configuration, when the loading is resumed based on the tray ID and the number of sheets (number of sheets) to be loaded, it is possible to determine what number of sheets of glass original sheets to be loaded on the tray and what number of sheets of glass original sheets to be loaded next are on the tray. Therefore, even if the loading is interrupted halfway, the original plate data can be restarted and stored in the correct loading order, and the glass original plate can be loaded up to the full number.

Specifically, the data management unit 71 associates the notified tray ID with the number of similarly notified loads, and registers the number of loads in the loading interrupt information 512. The data management unit 71 may register a status of "interrupt" indicating that the current loading job is interrupted in association with the tray ID.

When the loading operation on the interrupted tray 14 is restarted, the loader 13 transmits the tray ID of the read tray 14 to the original plate process apparatus 10, and notifies the original plate process apparatus 10 of the restart of the loading operation on the tray 14 corresponding to the tray ID.

When the number of loads corresponding to the notified tray ID is registered in the loading interruption information 512, the data management unit 71 returns the number of loads to the loader 13.

The loader 13 can restart the loading of the glass raw sheet G from the next number of loads based on the number of loads received. When loading of the glass raw sheet G is completed to a predetermined number, the loader 13 may send the tray ID and the number of sheets to be loaded to the raw sheet processing apparatus 10, and notify the raw sheet processing apparatus 10 that loading is completed.

Upon receiving a notification indicating that loading is completed from the loader 13, the data management unit 71 may delete various pieces of information corresponding to the tray ID included in the notification from the loading interruption information 512. Alternatively, the data management unit 71 may register the tray ID, the number of completed loads, and the status of "completed" indicating completion of loading in the loading interruption information 512.

< interrupt regarding machining operation >

In the present embodiment, the processing device 20 may control progress of the processing operation of the glass raw plate G in the work target tray using the tray ID, as an example.

In the present embodiment, the machining interruption information 612 may be stored in the storage unit 61 of the machining process device 20. The processing interruption information 612 is information indicating the progress of the processing operation of the glass raw plate G in the work object tray for each tray 14.

In the present embodiment, the control unit 60 further includes a process management unit 84. The process management unit 84 uses the processing interruption information 612 to manage progress of the processing operation of the glass raw plate G in the work object tray.

Fig. 8 is a diagram showing an example of a data structure of the processing interruption information 612. As an example, the processing interruption information 612 is composed of two data items, that is, a tray ID and the number of removed sheets. In other examples, the process interruption information 612 may have a status data item, if desired.

The tray ID is identification information that uniquely identifies the tray 14. The number of sheets taken out is information indicating the number of sheets of glass raw sheets G taken out from the tray 14. The number of sheets taken out may be expressed as a fraction of a numerator, taking the full number of the tray 14 as a denominator, and taking the number of sheets taken out from the tray 14 as a numerator, for example. The status indicates information of progress of the machining operation with respect to the tray 14.

In the present embodiment, the reader 21 or another reader not shown reads the tray ID of the tray 14 from the information recording medium 16. Before starting processing of the glass raw sheet G loaded on the tray 14, the processing machine 22 acquires the tray ID of the tray 14 via the reader 21 or another reader not shown. The processing machine 22 transmits the acquired tray ID to the processing device 20, and notifies the processing device 20 that the processing operation of the tray 14 corresponding to the tray ID is to be started.

The process management unit 84 of the machining process device 20 registers the notified tray ID in the machining interruption information 612. The process management unit 84 may register a status indicating that the current machining operation is in "machining" in association with the pallet ID.

When the processing machine 22 interrupts the processing operation in a state where the glass original plate G remains on the tray 14, the tray ID of the tray 14 in which the processing is interrupted and the number of removed sheets after the completion of the removal from the tray 14 are transmitted to the processing device 20, and the processing device 20 is notified of the interruption of the processing operation.

The process management unit 84 may perform a process recording step of storing a tray ID (tray identification information) for identifying the tray 14 in the storage unit 61 in association with the number of taken out sheets indicating the number of glass raw sheets G taken out from the tray 14. The information associating the tray ID with the number of taken out sheets is not limited to being stored in the storage unit 61, and may be stored in any storage device that can be referred to by the processing device 20, such as the storage device 30.

According to the above configuration, based on the tray ID and the number of removed sheets, when the removal is restarted, it is possible to determine what number of glass sheets the glass sheet or the like removed from the tray is mounted on. Therefore, even if the processing is interrupted in the middle of the process, accurate original plate data corresponding to the glass original plate taken out at the time of restarting can be read out, and the process can be restarted.

Specifically, the process management unit 84 associates the notified tray ID with the same number of removed sheets, and registers the same number of removed sheets in the processing interruption information 612. The process management unit 84 may further register a state of "interrupt" indicating that the current machining operation is interrupted in association with the pallet ID.

When resuming the machining operation for the interrupted tray 14, the machining machine 22 reads the tray ID of the tray 14, transmits the read tray ID to the machining process device 20, and notifies the machining process device 20 of resuming the machining operation for the tray 14 corresponding to the tray ID.

When the number of removed sheets corresponding to the notified tray ID is registered in the processing interruption information 612, the process management unit 84 returns the number of removed sheets to the processing machine 22.

The processing machine 22 can restart the removal of the glass raw sheet G from the number of removed sheets based on the number of received removed sheets. The data output unit 83 can output the original plate data to the processing machine 22 in order from the original plate data of the glass original plate G that is restarted. When the processing of all the glass raw sheets G on the tray 14 is completed, the processing machine 22 may send the tray ID to the processing device 20, and notify the processing device 20 of the completion of the removal and processing.

When a notification to the effect that the processing of the tray 14 is completed is received from the processing machine 22, the process management unit 84 may delete various pieces of information corresponding to the tray ID included in the notification from the processing interruption information 612. Alternatively, the process management unit 84 may register the tray ID and the status of "complete" indicating completion of the machining in the machining interruption information 612.
