Description

精整作業支援装置、精整作業支援方法及び精整作業支援システムRefining work support device, refining work support method, and refining work support system
　本発明は、鋼板の精整作業を支援する精整作業支援装置、精整作業支援方法及び精整作業支援システムに関する。
　本願は、２０１２年０２月０６日に、日本に出願された特願２０１２－０２３１７３号に基づき優先権を主張し、その内容をここに援用する。 The present invention relates to a refining work support device, a refining work support method, and a refining work support system that support a refining work of a steel sheet.
This application claims priority based on Japanese Patent Application No. 2012-023173 filed in Japan on February 06, 2012, the contents of which are incorporated herein by reference.
　鋼板の精整作業は、疵の研削等による除去の他、寸法測定、ステンシル印字、打刻など、多岐にわたっている。現在、作業者への作業指示は、作業指示票として印刷された紙片によりなされている。この作業指示の内容には、前工程である検査工程他において、入力された結果が反映されている。 Steel sheet refining work covers a wide range, such as removal by scissor grinding etc., dimension measurement, stencil printing, and stamping. Currently, work instructions to workers are made with paper pieces printed as work instruction forms. The contents of this work instruction reflect the input results in the inspection process, which is the previous process.
精整作業は、対象素材である鋼板が工程に到着した時点で、作業者がこの作業指示票と照らし合わせながら、対象素材の表面を再度検査し、手入れ箇所の記入、寸法測定位置の確認、ステンシルによる印字および打刻の必要性等について判断した後に、開始する。 In the refining work, when the steel plate that is the target material arrives at the process, the operator re-inspects the surface of the target material against the work instruction sheet, fills in the care location, confirms the dimension measurement position, Start after judging the need for printing and stamping with a stencil.
精整作業が完了した後には、作業員が再度、対象素材である鋼板表面を確認し、その結果を作業指示票に手書きで記入の上、精整作業結果をビジネスコンピュータに入力して一連の作業工程を終了する。 After the finishing work is completed, the worker again checks the surface of the target steel plate, fills the result with handwriting on the work instruction sheet, and enters the finishing work result into the business computer. Finish the work process.
近年は、作業指示票を電子化して、タブレット型端末に画像表示することでペーパーレス化を行っている。また、寸法測定結果は、前工程から電子情報として送信し、該タブレット型端末側で受信することで、作業負担軽減を図っている。さらに、タブレット型端末への表示のために、疵検査工程においては、疵位置を座標情報として入力している。 In recent years, paperless work has been performed by digitizing work instruction forms and displaying images on tablet terminals. In addition, the result of dimension measurement is transmitted as electronic information from the previous process, and is received by the tablet terminal, thereby reducing the work load. Further, for display on the tablet terminal, the eyelid position is input as coordinate information in the eyelid inspection process.
しかしながら、対象素材上にステンシルや打刻等を行うマーキング作業、その後の精整作業及び作業終了後の確認作業など、複数回に及ぶ作業員による鋼板上での作業を必要とする点は、以前と変わりない。このため、作業能率向上や作業員の安全確保の面では、更なる改善が求められていた。 However, points that require work on the steel sheet by a number of workers, such as marking work that performs stencil and stamping on the target material, subsequent refining work and confirmation work after work, And no different. For this reason, further improvements have been demanded in terms of improving work efficiency and ensuring worker safety.
特許文献１には、鋼板の疵取り方法に、ＣＣＤ撮像装置を備えた自走式疵取り装置を使用することが開示されている。この装置によって疵取り作業は自動化されるものの、その疵取り作業に先立って鋼板に、疵の種類に応じた各種マーキング、寸法測定、打刻などを施す作業については、自動化されておらず、作業員によるマーキングなどの作業が必要である点は、従来通りである。 Patent Document 1 discloses that a self-propelled scoring device equipped with a CCD imaging device is used for a steel plate scoring method. Although this equipment automates the scraping work, prior to the scraping work, the work of performing various markings, dimensional measurement, stamping, etc. according to the type of the hook on the steel sheet is not automated. It is the same as in the past that an operation such as marking by an operator is necessary.

The steel plant production management system 600 includes, for example, a three-layer hierarchical system including an upper layer business computer 2, a middle layer process computer 3 and a database server 4, a lower layer process facility 5 and a field device 6. Consists of.
ビジネスコンピュータ２は、製鉄プラントにおける鋼板１００の生産計画を統括的に管理する最上位コンピュータであり、上位ネットワークＨＮを介してプロセスコンピュータ３と通信可能に接続されている。このビジネスコンピュータ２には、鋼板１００の客先仕様（客先が要求する鋼板１００の厚さ、長さ、幅の各寸法や平坦度等の各仕様）の他、上記精整関連情報の内、疵取り作業に必要な精整基準及び精整方法と、ステンシル作業で使用されるステンシルテンプレートの番号や印字箇所のＸＹ座標などの各種情報が予め登録されている。 The business computer 2 is a top-level computer that comprehensively manages the production plan of the steel plate 100 in the steel plant, and is connected to the process computer 3 via the host network HN so as to be communicable. The business computer 2 includes a customer specification of the steel plate 100 (specifications of thickness, length, width, flatness, etc. of the steel plate 100 required by the customer), as well as the above refining related information. Various kinds of information such as a refining standard and a refining method necessary for the scraping work, and the number of the stencil template used in the stencil work and the XY coordinates of the printing location are registered in advance.
プロセスコンピュータ３は、上位ネットワークＨＮを介してビジネスコンピュータ２と通信可能に接続されていると共に、下位ネットワークＬＮを介してデータベースサーバ４、プロセス設備５及びフィールド機器６と通信可能に接続されている。このプロセスコンピュータ３は、フィールド機器６から受信したプロセスデータ（温度やテーブル回転数、流量、圧力等の測定データ）と、ビジネスコンピュータ２から受信した生産計画及び客先仕様に基づいて各工程のプロセス設備５を制御したり、上記生産計画及び客先仕様に基づく製造指示や上記プロセスデータを各工程の作業者に表示するコンピュータである。 The process computer 3 is communicably connected to the business computer 2 via the host network HN, and is communicably connected to the database server 4, the process facility 5, and the field device 6 via the lower network LN. The process computer 3 processes each process based on the process data received from the field device 6 (measurement data such as temperature, table rotation speed, flow rate, pressure, etc.) and the production plan and customer specifications received from the business computer 2. It is a computer that controls the equipment 5 and displays manufacturing instructions based on the production plan and customer specifications and the process data to workers in each process.
データベースサーバ４は、下位ネットワークＬＮを介してフィールド機器６から受信したプロセスデータや、表面検査工程から得られた鋼板１００の表面検査データなどの各種データをデータベース化して管理するコンピュータである。なお、鋼板１００には、１枚ごとに製造番号が割り振られており、上記の表面検査データは、各鋼板１００の製造番号に対応付けられてデータベース化されている。 The database server 4 is a computer that manages various data such as process data received from the field device 6 via the lower network LN and surface inspection data of the steel plate 100 obtained from the surface inspection process in a database. A production number is assigned to each steel plate 100, and the surface inspection data is stored in a database in association with the production number of each steel plate 100.
プロセス設備５は、例えば圧延機や切断機等の各工程の生産設備の他、ベルトコンベア等の搬送設備なども含む。なお、実際にプロセスコンピュータ３による制御に応じてプロセス設備５を動作させるものは、プロセス設備５に設けられたＰＬＣ(Programmable Logic Controller)などの下位制御装置である。
フィールド機器６は、プロセス設備５に設けられた、温度計や回転数計、流量計、圧力計、バルブポジショナ等の計測機器類である。 The process equipment 5 includes, for example, production equipment for each process such as a rolling mill and a cutting machine, as well as transport equipment such as a belt conveyor. Note that what actually operates the process equipment 5 in accordance with control by the process computer 3 is a lower-level control device such as a PLC (Programmable Logic Controller) provided in the process equipment 5.
The field device 6 is a measuring device such as a thermometer, a tachometer, a flow meter, a pressure gauge, or a valve positioner provided in the process facility 5.
精整作業支援装置１の制御装置１３は、上述した生産管理システム６００の下位ネットワークＬＮに接続されており、データベースサーバ４から鋼板１００の表面検査データを取得すると共に、プロセスコンピュータ３を介してビジネスコンピュータ２から鋼板１００の疵取り作業に必要な精整基準及び精整方法と、ステンシルテンプレートの番号や印字箇所のＸＹ座標などの各種情報を取得する。 The control device 13 of the refining work support device 1 is connected to the lower network LN of the production management system 600 described above, acquires the surface inspection data of the steel plate 100 from the database server 4, and performs business via the process computer 3. From the computer 2, various information such as a refining standard and a refining method necessary for the work of scraping the steel plate 100, the number of the stencil template, and the XY coordinates of the printing location are acquired.
このように、製鉄プラントの生産管理システム６００に精整作業支援装置１を接続し、ビジネスコンピュータ２及びデータベースサーバ４を、精整作業支援装置１に精整関連情報を提供する情報管理装置として利用することにより、本発明の精整作業支援システム５００を構築することができる。
なお、図２に示した精整作業支援システム５００では、鋼板１００の精整関連情報が、ビジネスコンピュータ２とデータベースサーバ４とに別々に分かれて登録されているので、ビジネスコンピュータ２から精整作業支援装置１へ精整関連情報の一部を送信する場合に、プロセスコンピュータ３を経由する必要がある。
つまり、図２に示した精整作業支援システム５００では、プロセスコンピュータ３が必須の構成要素となっているが、精整関連情報を一つのコンピュータ（情報管理装置）で一元管理し、そのコンピュータと精整作業支援装置１とを直接通信可能とすることにより、プロセスコンピュータ３が不要な精整作業支援システムを構築することもできる。 In this way, the refining work support device 1 is connected to the production management system 600 of the steel plant, and the business computer 2 and the database server 4 are used as information management devices that provide refining related information to the refining work support device 1. By doing so, the finishing work support system 500 of the present invention can be constructed.
In the refining work support system 500 shown in FIG. 2, the refining related information of the steel plate 100 is separately registered in the business computer 2 and the database server 4. When a part of the refining related information is transmitted to the support device 1, it is necessary to go through the process computer 3.
That is, in the refining work support system 500 shown in FIG. 2, the process computer 3 is an indispensable component, but the refining related information is centrally managed by one computer (information management device), and the computer and By enabling direct communication with the finishing work support device 1, a finishing work support system that does not require the process computer 3 can be constructed.
　次に、精整作業支援装置１の動作について説明する。
　図３Ａ及び図３Ｂは、精整作業支援装置１の動作フローチャートである。まず、図３Ａに示すように、制御装置１３は、精整作業工程の作業台に鋼板１００が載置されたことを検知すると、撮像装置１１から入力される撮影画像データ（つまり、鋼板表面１０１の撮影画像）に基づいて、鋼板表面１０１の所定箇所に印字されている鋼板１００の製造番号を読み取る（ステップＳ１）。 Next, the operation of the finishing work support device 1 will be described.
3A and 3B are operation flowcharts of the finishing work support device 1. First, as shown in FIG. 3A, when the control device 13 detects that the steel plate 100 is placed on the workbench in the refining work process, the photographic image data (that is, the steel plate surface 101) input from the imaging device 11 is detected. The serial number of the steel plate 100 printed at a predetermined location on the steel plate surface 101 is read (step S1).
　続いて、制御装置１３は、データベースサーバ４から鋼板１００の製造番号に対応する表面検査データを取得して内部メモリに記憶する（ステップＳ２）。さらに、制御装置１３は、プロセスコンピュータ３を介して、ビジネスコンピュータ２から鋼板１００の疵取り作業に必要な精整基準及び精整方法と、ステンシル作業に使用するステンシルテンプレートの番号と印字箇所のＸＹ座標などの各種情報を取得して内部メモリに記憶する（ステップＳ３）。これにより、制御装置１３の内部メモリには、全ての精整関連情報が記憶される。 Subsequently, the control device 13 acquires surface inspection data corresponding to the production number of the steel plate 100 from the database server 4 and stores it in the internal memory (step S2). Further, the control device 13 is connected via the process computer 3 with a refining standard and a refining method necessary for scraping the steel plate 100 from the business computer 2, a stencil template number used for the stencil work, and an XY of the printing location. Various information such as coordinates is acquired and stored in the internal memory (step S3). Thereby, all the adjustment related information is stored in the internal memory of the control device 13.
　続いて、制御装置１３は、内部メモリに記憶されている精整関連情報と、撮像装置１１から入力される撮影画像データとに基づいて、鋼板表面１０１における精整箇所の周囲に、上記精整関連情報の内、その精整箇所での精整作業に必要な情報が作業支援情報として表示されるようレーザ描画装置１２を制御する（ステップＳ４）。 Subsequently, the control device 13 performs the above-mentioned adjustment on the periphery of the adjustment portion on the steel plate surface 101 based on the adjustment-related information stored in the internal memory and the captured image data input from the imaging device 11. The laser drawing apparatus 12 is controlled so that information necessary for the refining work at the refining location is displayed as work support information among the related information (step S4).
　具体的には、上記ステップＳ４において、制御装置１３は、まず、撮影画像データに基づく画像処理によって、鋼板１００の特定の角を座標原点Ｏとして認識すると共に、この座標原点Ｏから延びる鋼板１００の長辺と短辺をそれぞれＸ軸とＹ軸として認識する（図１参照）。そして、制御装置１３は、上記のように認識したＸＹ座標系と、内部メモリに記憶されている表面疵のＸＹ座標及び印字箇所のＸＹ座標とから、鋼板表面１０１における各精整箇所の位置を把握する。 Specifically, in step S4, the control device 13 first recognizes a specific corner of the steel plate 100 as the coordinate origin O by image processing based on the captured image data, and the steel plate 100 extending from the coordinate origin O. The long side and the short side are recognized as the X axis and the Y axis, respectively (see FIG. 1). And the control apparatus 13 determines the position of each refinement | positioning location in the steel plate surface 101 from the XY coordinate system recognized as mentioned above, the XY coordinate of the surface flaw memorize | stored in internal memory, and the XY coordinate of a printing location. To grasp.
そして、図４に示すように、制御装置１３は、鋼板表面１０１において、例えば精整作業として疵取り作業が行われる精整箇所（つまり表面疵の位置）Ｐ１の周囲には、内部メモリに記憶されている精整関連情報の内、疵コード、精整基準及び精整方法が作業支援情報Ｗ１として表示されるようレーザ描画装置１２を制御する。 Then, as shown in FIG. 4, the control device 13 stores, in the internal memory, around the refining portion (that is, the position of the surface wrinkle) P1 on the steel plate surface 101 where the wringing operation is performed as a refining operation, for example. The laser drawing apparatus 12 is controlled so that the wrinkle code, the refining standard, and the refining method are displayed as the work support information W1 among the refining related information.
ここで、図４に示すように、作業支援情報Ｗ１として、例えば「４０１」、「５Ｌ８Ｙ６」、「０２０１５」という文字が配列されているとする。「４０１」が表面疵の種類を示す疵コードである。「５Ｌ８Ｙ６」の内、「５」は外観基準、「Ｌ」は手入れ方法、「８」は番手、「Ｙ」は溶接補修の可否、「６」は溶接条件を示している。「０２０１５」は下限板厚を示している。 Here, as shown in FIG. 4, it is assumed that, for example, characters “401”, “5L8Y6”, and “02015” are arranged as the work support information W1. “401” is a wrinkle code indicating the type of surface wrinkles. Of “5L8Y6”, “5” indicates an appearance standard, “L” indicates a care method, “8” indicates a count, “Y” indicates whether welding repair is possible, and “6” indicates welding conditions. “0205” indicates the lower limit plate thickness.
つまり、このような作業支援情報Ｗ１が精整箇所Ｐ１の周囲に表示されることにより、精整作業を行う作業者は、表面疵の状態に加えて、精整基準として５番の外観基準を用いること、精整方法として粗さが８番の番手（研削材）を使用して圧延方向（Ｌ方向）に表面疵を研削する方法を用いること、但し、下限板厚を遵守するために６番の溶接条件による溶接補修（または、補修溶接）も可能であること、などの精整作業（疵取り作業）に必要な情報を容易に認識することができる。 That is, such work support information W1 is displayed around the refining point P1, so that the worker who performs the refining work uses the appearance standard No. 5 as the refining standard in addition to the surface flaw state. Use a method of grinding surface flaws in the rolling direction (L direction) using a number 8 (grinding material) having a roughness of 8 as a finishing method, provided that 6 is used to comply with the lower limit thickness. It is possible to easily recognize information necessary for refining work (scraping work) such as welding repair (or repair welding) according to the welding condition of the number.
また、同じく図４に示すように、制御装置１３は、鋼板表面１０１において、例えば精整作業としてステンシル作業が行われる精整箇所（つまりステンシル作業による印字箇所）Ｐ２の周囲には、ステンシルテンプレートの番号（例えば「Ｎｏ．３」）が作業支援情報Ｗ２として表示されるようレーザ描画装置１２を制御する。つまり、このような作業支援情報Ｗ２が精整箇所Ｐ２の周囲に表示されることにより、精整作業を行う作業者は、３番のステンシルテンプレートを用いてステンシル作業を行うという、精整作業（ステンシル作業）に必要な情報を容易に認識することができる。 Also, as shown in FIG. 4, the control device 13 has a stencil template on the steel plate surface 101 around a refining location (that is, a printing location by the stencil operation) P2 where a stencil operation is performed as a refining operation. The laser drawing device 12 is controlled so that the number (for example, “No. 3”) is displayed as the work support information W2. That is, such work support information W2 is displayed around the refining point P2, so that the worker who performs the refining work performs a refining work (stencil work using the third stencil template). Information necessary for stencil work) can be easily recognized.
なお、図４では、精整箇所Ｐ１、Ｐ２の右隣りに作業支援情報Ｗ１、Ｗ２を表示する場合を例示しているが、精整作業の妨げとならない位置であれば、平面的に視て精整箇所Ｐ１、Ｐ２の上下左右のどの位置に作業支援情報Ｗ１、Ｗ２を表示しても良い。また、精整箇所Ｐ１、Ｐ２と作業支援情報Ｗ１、Ｗ２との間の距離に特に制限はないが、作業支援情報Ｗ１、Ｗ２の表示により作業者に精整箇所Ｐ１、Ｐ２の位置を認識させるという観点からも、可能な限り精整箇所Ｐ１、Ｐ２に近い位置に作業支援情報Ｗ１、Ｗ２を表示することが好ましい。 FIG. 4 illustrates the case where the work support information W1 and W2 are displayed on the right side of the finishing points P1 and P2. However, if it is a position that does not hinder the finishing work, see the plan view. The work support information W1, W2 may be displayed at any position on the top / bottom / left / right sides of the adjustment points P1, P2. Further, although there is no particular limitation on the distance between the refined places P1 and P2 and the work support information W1 and W2, the worker can recognize the positions of the refined places P1 and P2 by displaying the work support information W1 and W2. From this point of view, it is preferable to display the work support information W1 and W2 at positions as close as possible to the refined places P1 and P2.
さらに、図４に示すように、制御装置１３は、鋼板表面１０１の各精整箇所Ｐ１、Ｐ２において、上記作業支援情報Ｗ１、Ｗ２と共に、作業終了マーク記入領域Ｂ１及び追加工程コード記入領域Ｂ２が表示されるようレーザ描画装置１２を制御する。作業終了マーク記入領域Ｂ１は、作業者が、精整箇所Ｐ１、Ｐ２での精整作業終了時に、作業終了マーク（例えばＶ字マーク）を記入するための領域である。追加工程コード記入領域Ｂ２は、精整箇所Ｐ１、Ｐ２での精整作業終了時に追加の作業が必要となった場合に、追加作業が行われる追加工程を示す追加工程コード（例えば３桁の数字）を記入するための領域である。 Further, as shown in FIG. 4, the control device 13 includes a work end mark entry area B1 and an additional process code entry area B2 together with the work support information W1 and W2 in each of the refined locations P1 and P2 of the steel plate surface 101. The laser drawing device 12 is controlled so as to be displayed. The work end mark entry area B1 is an area for the operator to enter a work end mark (for example, a V-shaped mark) when finishing the finishing work at the finishing points P1 and P2. The additional process code entry area B2 is an additional process code (for example, a three-digit number) indicating an additional process to be performed when additional work is required at the end of the finishing work at the finishing points P1 and P2. ) Is an area for filling in.
　以上のようなステップＳ４の処理によって、鋼板表面１０１における各精整箇所Ｐ１、Ｐ２の周囲に、各精整箇所Ｐ１、Ｐ２での精整作業に必要な情報が作業支援情報Ｗ１、Ｗ２として表示されて、作業者が鋼板表面１０１で精整作業を行う準備が整うことになる。これにより、作業者は容易に鋼板表面１０１の各精整箇所Ｐ１、Ｐ２の位置と、各精整箇所Ｐ１、Ｐ２での精整作業に必要な情報を認識することができ、その結果、鋼板１００の精整作業能率の向上と作業者の負担軽減を実現できる。 Through the processing in step S4 as described above, information necessary for the refining work at the refining points P1 and P2 is displayed as work support information W1 and W2 around the refining points P1 and P2 on the steel plate surface 101. Thus, the operator is ready to perform the refining work on the steel plate surface 101. As a result, the operator can easily recognize the positions of the refining points P1 and P2 on the steel plate surface 101 and information necessary for the refining work at the refining points P1 and P2. Improvement of 100 finishing work efficiency and reduction of operator's burden can be realized.
　続いて、図３Ａに示すように、制御装置１３は、撮像装置１１から入力される撮影画像データに基づいて、作業者が現在精整作業を行っている精整箇所（以下、現精整箇所と称す）を特定すると共に、現精整箇所での作業者の動作を認識し、作業者が特定の動作をしたか否かを判定する（ステップＳ５）。なお、撮影画像データに基づく画像処理によって人物の動作を認識する技術としては、例えば特開２００９－１７６０５９号公報に記載の技術など、既に公知の技術を利用することができる。 Subsequently, as illustrated in FIG. 3A, the control device 13 performs a refining location (hereinafter, current refining location) where the worker is currently performing a refining operation based on the captured image data input from the imaging device 11. And the operator's motion at the current refined location is recognized, and it is determined whether the worker has performed a specific motion (step S5). As a technique for recognizing a person's movement by image processing based on photographed image data, a known technique such as the technique described in Japanese Patent Application Laid-Open No. 2009-176059 can be used.
制御装置１３は、上記ステップＳ５にて「Ｎｏ」の場合には、後述のステップＳ７の処理に移行する一方、上記ステップＳ５にて「Ｙｅｓ」の場合には、認識した作業者の動作に応じて、現精整箇所における作業支援情報の表示状態が変化するようレーザ描画装置１２を制御する（ステップＳ６）。 If “No” in step S5, the control device 13 proceeds to a process in step S7 described later. If “Yes” in step S5, the control device 13 responds to the recognized operation of the worker. Then, the laser drawing device 12 is controlled so that the display state of the work support information at the current refined location changes (step S6).
　具体的には、上記ステップＳ６において、制御装置１３は、レーザ描画装置１２の制御により、作業者の動作に応じて、例えば、作業支援情報の表示と非表示の切替え、作業支援情報の表示位置の変更、作業支援情報の表示サイズの変更、及び作業支援情報に関する補足情報の追加表示のうちの少なくとも一つを行う。 Specifically, in step S6, the control device 13 controls the display of the work support information, for example, switching between display and non-display of the work support information according to the operation of the operator under the control of the laser drawing device 12. At least one of change of the display, change of the display size of the work support information, and additional display of supplementary information related to the work support information.
　上記のように、作業者の動作に応じて、例えば、作業支援情報の表示と非表示の切替え、または作業支援情報の表示位置の変更を行うことにより、作業支援情報の表示が精整作業の妨げとなることを防止することができる。また、作業者の動作に応じて、例えば、作業支援情報の表示サイズの変更を行うことで、作業者による作業支援情報の視認を容易とすることができる。また、作業者の動作に応じて、例えば、作業支援情報に関する補足情報の追加表示を行うことにより、作業者による作業支援情報の理解を容易とすることができる。 As described above, according to the operation of the worker, for example, the display of work support information is switched between display and non-display, or the display position of the work support information is changed. It can be prevented from hindering. Further, for example, by changing the display size of the work support information according to the operation of the worker, the work support information can be easily viewed by the worker. Further, for example, by additionally displaying supplementary information related to the work support information in accordance with the operation of the worker, the worker can easily understand the work support information.
　このように、制御装置１３に、精整作業を行う作業者の動作を認識し、作業支援情報の表示状態が作業者の動作に応じて変化するようレーザ描画装置１２を制御する機能を持たせることにより、作業者が作業支援情報の表示状態を意図的に変化させることができるようになるので、精整作業能率をさらに向上できる。 As described above, the control device 13 has a function of recognizing the operation of the worker who performs the refining work and controlling the laser drawing device 12 so that the display state of the work support information changes according to the operation of the worker. As a result, the worker can intentionally change the display state of the work support information, so that the precision work efficiency can be further improved.
　なお、制御装置１３が、上記ステップＳ５にて「Ｙｅｓ」の場合に、認識した作業者の動作が周辺装置の操作に関するものであれば、その作業者の動作に応じて周辺装置を制御するステップを別に設けても良い。ここで、周辺装置とは、精整作業工程に設置されている、精整作業支援装置１以外の他の装置を指す。例えば、周辺装置が鋼板表面１０１を照らす照明装置である場合、制御装置１３は、認識した作業者の動作に応じて上記照明装置の明るさを制御する。 In the case where the control device 13 is “Yes” in step S5, if the recognized operation of the worker relates to the operation of the peripheral device, the step of controlling the peripheral device according to the operation of the worker May be provided separately. Here, the peripheral device refers to a device other than the refining work support device 1 installed in the refining work process. For example, when the peripheral device is a lighting device that illuminates the steel plate surface 101, the control device 13 controls the brightness of the lighting device according to the recognized operation of the worker.
これにより、作業者が現精整箇所における作業支援情報の内容を確認する際には、照明装置の明るさを暗くして作業支援情報の視認性を向上でき、作業者が現精整箇所で精整作業を行う際には、照明装置の明るさを明るくして作業性を向上できる。このように、制御装置１３に、精整作業を行う作業者の動作を認識し、作業者の動作に応じて周辺装置を制御する機能を持たせることにより、作業者が鋼板１００上で作業しながら周辺装置を遠隔操作できるようになるので、精整作業能率をさらに向上できる。 As a result, when the worker confirms the contents of the work support information at the current refinement location, the brightness of the lighting device can be reduced to improve the visibility of the work support information. When performing the finishing work, the brightness of the lighting device can be increased to improve workability. As described above, the control device 13 recognizes the operation of the worker who performs the refining work and has a function of controlling the peripheral device according to the operation of the worker, so that the worker can work on the steel plate 100. However, since the peripheral device can be remotely operated, the efficiency of the refining work can be further improved.
　続いて、制御装置１３は、撮像装置１１から入力される撮影画像データに基づいて、現精整箇所の周囲に作業支援情報と共に表示されている作業終了マーク記入領域に作業終了マーク（例えばＶ字マーク）が記入されたか否かを判断する（ステップＳ７）。このような作業終了マークは、作業者が現精整箇所での精整作業が終了した時点で、例えば白墨などを利用して記入したものである。
　制御装置１３は、上記ステップＳ７にて「Ｎｏ」の場合、上記ステップＳ５の処理に戻って作業者の動作を監視する一方、上記ステップＳ７にて「Ｙｅｓ」の場合、現精整箇所での精整作業が終了したと判断する（ステップＳ８）。
　なお、必ずしも作業終了マーク記入領域を鋼板表面１０１に表示させる必要はなく、現精整箇所の周囲に作業終了マークが記入されていれば、その現精整箇所での精整作業が終了したと判断する機能を制御装置１３に持たせても良い。 Subsequently, based on the captured image data input from the imaging device 11, the control device 13 sets a work end mark (for example, a V-character) in a work end mark entry area displayed together with the work support information around the current refinement location. It is determined whether or not (mark) has been entered (step S7). Such a work end mark is written by using, for example, white ink when the worker finishes the finishing work at the current finishing position.
In the case of “No” in step S7, the control device 13 returns to the process in step S5 and monitors the operation of the worker. On the other hand, in the case of “Yes” in step S7, the control device 13 It is determined that the finishing work has been completed (step S8).
In addition, it is not always necessary to display the work end mark entry area on the steel plate surface 101, and if the work end mark is written around the current refining location, the refining work at the current refining location has been completed. The control device 13 may have a function of determining.
　続いて、図３Ｂに示すように、制御装置１３は、撮像装置１１から入力される撮影画像データに基づいて、現精整箇所の周囲に作業支援情報と共に表示されている追加工程コード記入領域に追加工程コードが記入されたか否かを判定する（ステップＳ９）。このような追加工程コードは、作業者が現精整箇所での精整作業終了時に追加の作業が必要となった場合に、その追加作業が行われる追加工程をデータベースサーバ４に登録するために、例えば白墨などを利用して記入したものである。 Subsequently, as shown in FIG. 3B, the control device 13 enters the additional process code entry area displayed together with the work support information around the current refinement location based on the captured image data input from the imaging device 11. It is determined whether an additional process code has been entered (step S9). Such an additional process code is used for registering, in the database server 4, an additional process in which the additional work is performed when the worker needs an additional work at the end of the finishing work at the current finishing position. , For example, using white ink.
　制御装置１３は、上記ステップＳ９にて「Ｎｏ」の場合、後述のステップＳ１１の処理に移行する一方、上記ステップＳ９にて「Ｙｅｓ」の場合、追加工程コード記入領域に記入された追加工程コードを読み取ってデータベースサーバ４に送信する（ステップＳ１０）。このように、作業者が、現精整箇所において追加の作業が必要となった場合に、現精整箇所の追加工程コード記入領域に追加工程コードを記入するだけで、その追加工程コードがデータベースサーバ４に集められて（登録されて）閲覧可能となるので、精整作業工程の終了後に新たに追加された追加工程を容易に確認することができる。
なお、必ずしも追加工程コード記入領域を鋼板表面１０１に表示させる必要はなく、現精整箇所の周囲に追加工程コードが記入されていれば、それを読み取ってデータベースサーバ４に送信する機能を制御装置１３に持たせても良い。 If “No” in step S9, the control device 13 proceeds to the processing of step S11 described later, whereas if “Yes” in step S9, the additional process code entered in the additional process code entry area. Is transmitted to the database server 4 (step S10). In this way, when an additional work is required at the current refinement location, the operator simply enters the additional process code in the additional process code entry area at the current refinement location, and the additional process code is stored in the database. Since they are collected (registered) in the server 4 and can be viewed, it is possible to easily confirm the newly added additional process after the finishing work process.
Note that it is not always necessary to display the additional process code entry area on the steel plate surface 101. If the additional process code is entered around the current refined location, the control device has a function of reading it and transmitting it to the database server 4. 13 may be provided.
　続いて、制御装置１３は、全ての精整箇所での精整作業が終了したか、言い換えれば、全ての作業終了マーク記入領域に作業終了マークが記入されたか否かを判定する（ステップＳ１１）。制御装置１３は、上記ステップＳ１１にて「Ｎｏ」の場合、例えば図５に示すように、鋼板表面１０１の所定位置（例えば精整作業が終了したと判断した現精整箇所に隣接する位置）に、次に精整作業をすべき他の精整箇所を指し示す矢印ＡＲが表示されるようレーザ描画装置１２を制御する（ステップＳ１２）。なお、矢印ＡＲの表示位置は、作業者が認識しやすい位置ならば、どの位置でも良い。 Subsequently, the control device 13 determines whether or not the finishing work at all the finishing points has been completed, in other words, whether or not the work finishing marks have been entered in all the work finishing mark entry areas (step S11). . In the case of “No” in step S <b> 11, the control device 13, for example, as shown in FIG. 5, a predetermined position on the steel plate surface 101 (for example, a position adjacent to the current refinement location where it is determined that the refinement operation has been completed). Then, the laser drawing device 12 is controlled so that an arrow AR indicating another adjustment location where the adjustment operation should be performed next is displayed (step S12). The display position of the arrow AR may be any position as long as the operator can easily recognize it.
これにより、作業者は、鋼板表面１０１において、現精整箇所での精整作業が終了した後、次に精整作業をすべき他の精整箇所を容易に発見できるので、精整作業能率をさらに向上できる（特に鋼板１００のサイズが大きい場合に有効である）。なお、制御装置１３は、上記ステップＳ１２の終了後、上記ステップＳ５の処理に戻って、次の精整箇所での作業者の動作を監視する。 As a result, the operator can easily find another adjustment location to be adjusted next after finishing the adjustment operation at the current adjustment location on the steel plate surface 101. Can be further improved (especially effective when the size of the steel plate 100 is large). In addition, the control apparatus 13 returns to the process of the said step S5 after completion | finish of the said step S12, and monitors the operation | movement of the operator in the next refinement | positioning location.
　一方、制御装置１３は、上記ステップＳ１１にて「Ｙｅｓ」の場合、つまり全ての精整箇所の精整作業が終了したと判断した場合、例えば図６に示すように、鋼板表面１０１の所定位置（例えば中央位置）に全作業終了メッセージＭが表示されるようレーザ描画装置１２を制御する（ステップＳ１３）。これにより、作業者は、鋼板表面１０１において、全ての精整箇所での精整作業が終了したことを容易に認識できるので、精整作業能率をさらに向上できる。なお、全作業終了メッセージＭの表示位置は、作業者が認識しやすい位置ならば、どの位置でも良い。 On the other hand, in the case of “Yes” in Step S11 described above, that is, when it is determined that the refining work for all the refining locations has been completed, the control device 13, for example, as shown in FIG. The laser drawing apparatus 12 is controlled so that the all work end message M is displayed (for example, at the center position) (step S13). Thereby, since the operator can easily recognize that the finishing work has been completed at all the finishing points on the steel plate surface 101, the finishing work efficiency can be further improved. The display position of the all work end message M may be any position as long as it is easily recognized by the operator.
　以上説明したように、本実施形態によれば、作業者は容易に鋼板表面１０１における精整箇所の位置とその精整箇所での精整作業に必要な情報（作業支援情報）を認識することができ、その結果、鋼板１００の精整作業能率の向上と作業者の負担軽減を実現できる。 As described above, according to the present embodiment, the operator easily recognizes the position of the refinement location on the steel plate surface 101 and information (work support information) necessary for the refinement operation at the refinement location. As a result, it is possible to improve the efficiency of refining the steel plate 100 and reduce the burden on the operator.
　なお、本発明は上記実施形態に限定されず、以下のような変形例が挙げられる。
（１）例えば、制御装置１３に、撮像装置１１から入力される撮影画像データに基づいて、精整作業が終了したと判断した精整箇所の検査を行い、その検査結果をデータベースサーバ４に送信して閲覧可能とする機能を持たせても良い。
この機能を実現するには、図３Ａ及び図３Ｂに示すフローチャートにおいて、例えばステップＳ８とステップＳ９との後に、制御装置１３が、撮像装置１１から入力される撮影画像データに基づいて、精整作業が終了したと判断した現精整箇所の検査を行うステップと、制御装置１３が、その現精整箇所の検査結果をデータベースサーバ４に送信するステップとを設ければ良い。 In addition, this invention is not limited to the said embodiment, The following modifications are mentioned.
(1) For example, the control device 13 inspects a refined part that is determined that the refining work has been completed based on the captured image data input from the imaging device 11, and transmits the inspection result to the database server 4. It is also possible to provide a function that enables browsing.
In order to realize this function, in the flowcharts shown in FIGS. 3A and 3B, for example, after step S8 and step S9, the control device 13 performs an adjustment operation based on the captured image data input from the imaging device 11. It is only necessary to provide a step of inspecting the current refined location that is determined to be completed, and a step in which the control device 13 transmits the inspection result of the current refined location to the database server 4.
具体的には、制御装置１３は、例えば、疵取り作業を行った精整箇所の検査を行う場合、撮影画像データに基づく画像処理により、表面疵が外観基準を満たす程度に除去されたか否かを判断する。また、制御装置１３は、例えばステンシル作業を行った精整箇所の検査を行う場合には、撮影画像データに基づく画像処理により、ステンシル作業後に印字された文字が正しいか（ステンシル作業に使用されたステンシルテンプレートが正しいか）否かを判断する。
これにより、鋼板表面１０１において精整作業が終了した精整箇所を自動的に検査することができ、また、その検査結果がデータベースサーバ４に集められて閲覧可能となるので、精整作業工程の終了後における鋼板１００の品質チェックが容易となる。 Specifically, for example, when inspecting a refined place where the scoring operation has been performed, the control device 13 determines whether or not the surface wrinkles have been removed to the extent that the appearance standard is satisfied by image processing based on the captured image data. Judging. In addition, for example, when the control device 13 inspects a refined place where the stencil work has been performed, whether or not the characters printed after the stencil work are correct by image processing based on the captured image data (used for the stencil work). Determine if the stencil template is correct).
As a result, it is possible to automatically inspect the refining place where the refining work is finished on the steel plate surface 101, and the inspection results are collected in the database server 4 and can be viewed. The quality check of the steel plate 100 after the end becomes easy.
（２）例えば、制御装置１３に、撮像装置１１から入力される撮影画像データに基づいて、鋼板１００の寸法を測定すると共に、その寸法の測定値が所定の仕様（客先仕様）を満足するか否かを判定し、その判定結果と寸法の測定値とをデータベースサーバ４に送信して閲覧可能とする機能を持たせても良い。
　この機能を実現するには、図３Ｂのフローチャートにおいて、例えばステップＳ１３の後に、制御装置１３が、撮影画像データに基づいて鋼板１００の寸法（長さ及び幅の寸法）を測定するステップと、制御装置１３が、寸法の測定値が客先仕様を満足するか否かを判定するステップと、制御装置１３が、寸法の測定値が客先仕様を満足するか否かの判定結果と寸法の測定値とをデータベースサーバ４に送信するステップとを設ければ良い。
これにより、鋼板１００の寸法が客先仕様を満足するか否かを自動で判定することができ、また、その判定結果と寸法の測定値とがデータベースサーバ４に集められて閲覧可能となるので、精整作業工程の終了後における鋼板１００の寸法チェックが容易となる。 (2) For example, the control device 13 measures the dimensions of the steel plate 100 based on the captured image data input from the imaging device 11, and the measured value of the dimensions satisfies a predetermined specification (customer specification). It is possible to provide a function of determining whether or not and transmitting the determination result and the measured value of the dimension to the database server 4 so as to enable browsing.
In order to realize this function, in the flowchart of FIG. 3B, for example, after step S13, the control device 13 measures the dimensions (length and width dimensions) of the steel plate 100 based on the captured image data, and the control. The apparatus 13 determines whether or not the dimension measurement value satisfies the customer specification, and the control apparatus 13 determines whether or not the dimension measurement value satisfies the customer specification and the dimension measurement. A step of transmitting the value to the database server 4 may be provided.
Thereby, it is possible to automatically determine whether or not the dimensions of the steel plate 100 satisfy the customer specifications, and the determination results and the measured values of the dimensions are collected in the database server 4 and can be viewed. In addition, it becomes easy to check the dimensions of the steel plate 100 after the finishing operation process is completed.
（３）例えば、制御装置１３に、撮像装置１１から入力される撮影画像データに基づいて、精整作業を行う作業者が追加精整箇所（特に表面疵の位置）を指し示す動作を行ったことを認識した場合、鋼板表面１０１における追加精整箇所またはその周囲に、精整基準及び精整方法のみを含む作業支援情報と共に疵コード記入領域が表示されるようレーザ描画装置１２を制御する機能と、撮影画像データに基づいて疵コード記入領域に記入された疵コードを読み取り、その読み取った疵コードと追加精整箇所の位置情報（ＸＹ座標）とをデータベースサーバ４に送信して閲覧可能とする機能とを持たせても良い。 (3) For example, based on the captured image data input from the imaging device 11, the operator who performs the adjustment operation has performed an operation of pointing the additional adjustment location (particularly the position of the surface defect) to the control device 13. And the function of controlling the laser drawing device 12 so that the wrinkle code entry region is displayed together with the work support information including only the refining standard and the refining method at or around the additional refining location on the steel plate surface 101. Then, the heel code entered in the heel code entry area is read based on the photographed image data, and the read heel code and the position information (XY coordinates) of the additional refinement location are transmitted to the database server 4 so that they can be viewed. You may give a function.
　これらの機能を実現するには、図３Ａのフローチャートにおいて、例えばステップＳ４の後に、制御装置１３が、撮影画像データに基づいて、精整作業を行う作業者が追加精整箇所を指し示す動作を行ったことを認識するステップと、制御装置１３が、鋼板表面１０１における追加精整箇所またはその周囲に、精整基準及び精整方法のみを含む作業支援情報と共に疵コード記入領域が表示されるようレーザ描画装置１２を制御するステップと、制御装置１３が、撮影画像データに基づいて疵コード記入領域に記入された疵コードを読み取るステップと、制御装置１３が、読み取った疵コードと追加精整箇所のＸＹ座標とをデータベースサーバ４に送信するステップとを設ければ良い。 In order to realize these functions, in the flowchart of FIG. 3A, for example, after step S4, the control device 13 performs an operation in which an operator who performs a refining operation indicates an additional refining location based on the captured image data. And the control device 13 is configured to display the soot code entry area together with the work support information including only the refining standard and the refining method at or around the additional refining portion on the steel plate surface 101. A step for controlling the drawing device 12, a step for the control device 13 to read the wrinkle code written in the wrinkle code entry area based on the photographed image data, and a control device 13 for the read wrinkle code and the additional refinement location A step of transmitting the XY coordinates to the database server 4 may be provided.
これにより、作業者が鋼板表面１０１において新たな表面疵を発見した場合に、その表面疵の位置（追加精整箇所）に作業支援情報を表示させることができると共に、疵コード記入領域に疵コードを記入することにより、追加精整箇所の疵の状態も制御装置１３に入力させることができる。また、上記のように新たに追加した追加精整箇所のＸＹ座標と疵コードがデータベースサーバ４に登録されて閲覧可能となるので、作業者は、精整作業工程の終了後に、鋼板１００で新たに発見した表面疵の位置やその表面疵の状態を容易に確認することができる。 Thereby, when an operator discovers a new surface defect on the steel plate surface 101, the work support information can be displayed at the position of the surface defect (additional refinement location), and the defect code is entered in the defect code entry area. Can be input to the control device 13 as well. In addition, since the XY coordinates and the saddle code of the additional refined place newly added as described above are registered in the database server 4 and can be browsed, the worker can newly use the steel plate 100 after the finish work process. It is possible to easily confirm the position of the surface defects found in the above and the state of the surface defects.
（４）上記実施形態では、レーザ描画装置１２が描く作業支援情報に従って、作業者が鋼板表面１０１での精整作業を実施する場合を例示したが、鋼板表面１０１の面内方向（ＸＹ平面内の方向）及び面外方向（ＸＹ平面に直交するＺ軸方向）に移動自在な手入れ装置１４を設け、レーザ描画装置１２が描く作業支援情報を撮像装置１１で撮影し、制御装置１３が撮影画像データに基づいて上記手入れ装置１４を制御する構成を採用することにより、自動で精整作業を行うことができる。 (4) In the above embodiment, the case where the operator performs the refining work on the steel plate surface 101 in accordance with the work support information drawn by the laser drawing device 12 is illustrated, but the in-plane direction of the steel plate surface 101 (in the XY plane) ) And an out-of-plane direction (Z-axis direction orthogonal to the XY plane) are provided, and the work support information drawn by the laser drawing device 12 is taken by the imaging device 11, and the control device 13 takes the taken image. By adopting a configuration for controlling the care device 14 based on the data, it is possible to automatically perform the refining work.
　例えば、図７に示すように、手入れ装置１４は、門型フレーム２０、台車２１、支柱２２、ターレット機構２３、疵研削機構２４及び塗装印字機構２５によって構成される。具体的には、鋼板１００を跨いでＸ軸方向に移動自在な門型フレーム２０を設置し、この門型フレーム２０の上辺上をＹ軸方向に移動可能な台車２１を走行させて、台車２１が鋼板表面１０１の任意の位置に移動できるようにする。台車２１には、支柱２２が、台車２１と門型フレーム２０の上辺の溝を貫通して昇降自在に設置され、その下端には、ターレット機構２３を介して疵研削機構２４とスプレー式の塗装印字機構２５とが配設されている。すなわち、支柱２２は、ターレット機構２３をＺ軸方向に移動（昇降）させるものである。 For example, as shown in FIG. 7, the care device 14 includes a portal frame 20, a carriage 21, a support 22, a turret mechanism 23, a scissor grinding mechanism 24, and a paint printing mechanism 25. Specifically, a portal frame 20 that is movable in the X-axis direction across the steel plate 100 is installed, and a carriage 21 that can move in the Y-axis direction is caused to travel on the upper side of the portal frame 20. Can move to an arbitrary position on the steel plate surface 101. A pillar 22 is installed on the carriage 21 so as to freely move up and down through a groove on the upper side of the carriage 21 and the portal frame 20, and at its lower end, a turret mechanism 23 and a spray grinding mechanism 24 are sprayed. A printing mechanism 25 is provided. That is, the column 22 moves (lifts) the turret mechanism 23 in the Z-axis direction.
　このような構成では、レーザ描画装置１２で鋼板表面１０１に作業支援情報を描画した状態で、撮像装置１１により鋼板表面１０１を撮影し、制御装置１３が撮影画像に写る作業支援情報に基づいて、疵研削機構２４をＸＹＺ方向に移動させることにより、疵取り作業を自動で行うことができる。 In such a configuration, in a state where the work support information is drawn on the steel plate surface 101 by the laser drawing device 12, the steel plate surface 101 is photographed by the imaging device 11, and the control device 13 is based on the work support information reflected in the photographed image. By moving the scissor grinding mechanism 24 in the XYZ directions, the scissor removing operation can be performed automatically.
　表面疵が特殊である等の事情により、疵研削機構２４以外による作業が必要とする場合においては、ターレット機構２３により、塗装印字機構２５を表面疵の位置（精整箇所）に回転させて、製品番号や出荷先などを表示するためのステンシル作業等に用いることができる。
なお、図７では、手入れ装置１４が、疵研削機構２４及び塗装印字機構２５を備える場合を例示したが、疵研削機構、疵溶削機構、塗装印字機構及び打刻機構の内、少なくとも１つを備えていれば良い。ここで、疵研削機構とは、グラインダー等（例えば、砥石やベルトグラインダー）で、表面疵を機械的に研削し除去する機構をいう。疵溶削機構とは、エアアークガウジング又はガスガウジングにより、表面疵を除去する機構をいう。 When work other than the scissors grinding mechanism 24 is required due to circumstances such as special surface scissors, the turret mechanism 23 rotates the coating printing mechanism 25 to the position of the surface scissors (adjustment location), It can be used for stencil work for displaying a product number, a shipping destination, and the like.
7 illustrates the case where the care device 14 includes the scissor grinding mechanism 24 and the paint printing mechanism 25. However, at least one of the scissor grinding mechanism, the scissor welding mechanism, the paint printing mechanism, and the stamping mechanism is illustrated. As long as it has. Here, the scissor grinding mechanism refers to a mechanism that mechanically grinds and removes surface scissors with a grinder or the like (for example, a grindstone or a belt grinder). The soot cutting mechanism refers to a mechanism that removes surface soot by air arc gouging or gas gouging.
　以上のような手入れ装置１４を用いる構成を採用することにより、作業者による鋼板１００上での作業は、原則として不要となり、作業者の作業負担が大幅に軽減されて作業効率が大幅に向上すると共に、作業者の安全確保の面でも大きな効果がある。 By adopting the configuration using the care device 14 as described above, the work on the steel plate 100 by the operator becomes unnecessary in principle, the work burden on the worker is greatly reduced, and the work efficiency is greatly improved. At the same time, it has a great effect on ensuring the safety of workers.
　本発明によれば、鋼板の精整作業能率の向上と作業者の負担軽減を実現できるので、本発明を実施することにより、大きな産業上の効果を期待できる。 According to the present invention, it is possible to improve the efficiency of refining the steel sheet and reduce the burden on the operator. Therefore, by implementing the present invention, a great industrial effect can be expected.
