Description

生産改善支援システム、方法、及びプログラムProduction improvement support system, method, and program
　本開示は、生産改善支援システム、方法、及びプログラムに関する。 The present disclosure relates to a production improvement support system, method, and program.
　従来、生産ラインにおける改善活動は、ＰＤＣＡ（Ｐｌａｎ　Ｄｏ　Ｃｈｅｃｋ　Ａｃｔｉｏｎ）サイクルで成り立っていた。具体的には、時間測定と作業研究の視点で時間をかけて現状を観察した上で、改善に向けたアイデアをひねり出し、そのアイデアを適用し、時間をかけて評価する、というものである。 Previously, improvement activities on the production line consisted of a PDCA (Plan Do Check Action) cycle. Specifically, it takes time to observe the current situation from the viewpoints of time measurement and work research, then twists out ideas for improvement, applies the ideas, and evaluates them over time.
　しかし、昨今、生産ラインは、中品種中量生産、多品種少量生産へと変化している。また、製品のライフサイクルも短くなってきている。このような環境変化により、従来の改善手法では、時間がかかり過ぎるため生産形態の変化へ追随できず、また、手間がかかり過ぎて改善案を適用しにくい。その結果、生産ラインにおける生産性向上または原価低減が進みにくくなり、改善活動は低調気味になっていた。 However, these days, production lines have changed to medium- and medium-volume production, and high-mix, low-volume production. In addition, the product life cycle is becoming shorter. Due to such environmental changes, the conventional improvement methods take too much time to keep up with changes in the production form, and it takes too much effort to apply improvement plans. As a result, it has become difficult to improve productivity or reduce costs in the production line, and improvement activities have been sluggish.
　そこで、生産ラインにおける改善活動を簡易に行う試みとして、例えば、特許文献１には、作業者にビデオカメラを取り付けて作業内容を撮影し、撮影した画像を基にして作業内容の分析をする技術が開示されている。また、特許文献２には、作業者と設備との連合作業をカメラで撮影し、撮影した連合作業の動画を基にして、マンマシンチャートを表示する技術が開示されている。 Therefore, as an attempt to easily carry out improvement activities on a production line, for example, in Patent Document 1, a technique of attaching a video camera to an operator to photograph the work content and analyzing the work content based on the captured image is disclosed. Is disclosed. Further, Patent Document 2 discloses a technique of shooting a combined work of a worker and equipment with a camera and displaying a man-machine chart based on a moving image of the taken combined work.

　しかしながら、特許文献１に開示された技術では、作業をビデオカメラにより撮影する時に、作業者が手元スイッチを操作して作業の区切りを入力している。このため、作業者が、作業ごとに手元スイッチの操作をする必要があり、作業者への負担が大きいという問題がある。 However, in the technique disclosed in Patent Document 1, when the work is photographed by the video camera, the operator operates the hand switch to input the work break. For this reason, the worker needs to operate the hand switch for each work, which causes a problem that the burden on the worker is large.
　また、特許文献２に開示された技術では、マンマシンチャートを作成するために、分析者が、撮影した連合作業の動画の内容を確認しながら、手作業で作業ごとに区切りを設定しなくてはならない。このため、作業内容を分析するためには、分析者の手間と時間とがかかるという問題がある。 Further, in the technique disclosed in Patent Document 2, in order to create a man-machine chart, an analyst does not manually set a break for each work while checking the content of the video of the combined work taken by the analyst. Don't Therefore, there is a problem that it takes time and labor for the analyst to analyze the work content.
　本開示はこれらの課題を解決するためのものであり、作業者の負担を減らすとともに、分析を容易化することができる生産改善支援システム、方法、及びプログラムを提供することを目的とする。 The present disclosure is intended to solve these problems, and an object thereof is to provide a production improvement support system, method, and program that can reduce the burden on workers and facilitate analysis.
　上記目標を達成するために、本開示にかかる生産改善支援システムは、作業者の像とその作業者の状態とを対応付ける作業者状態マスタと、設備の像と作業者が使用している物品の像の組み合わせと作業を構成する要素作業とを対応付ける要素作業マスタとを保存する定義データベースと、作業者の状態の履歴と作業者が実行した要素作業の履歴とを保存する第１履歴データベースと、設備の稼働状態の履歴を保存する第２履歴データベースと、設備制御部と、画像取得部と、処理装置と、端末とを備える。設備制御部は、設備を制御し、この設備の稼働状態のデータを取得し、取得した稼働状態のデータを第２履歴データベースに保存する。画像取得部は、作業者と設備と作業者の用いている物品とを撮影した画像を取得する。処理装置は、取得した画像中の作業者の像を作業者状態マスタに適用して作業者の状態を特定し、特定した状態を示すデータを第１履歴データベースに保存し、また、取得した画像中の設備及び物品の像を要素作業マスタに適用して、作業者が実行した要素作業を特定し、特定した要素作業を示すデータを第１履歴データベースに保存する。端末は、第２履歴データベースと第１履歴データベースとに基づいて、設備の稼働状態及び作業者の状態の関係を示す情報と、要素作業の内容を示す情報とを生成して、出力する。 In order to achieve the above-mentioned target, the production improvement support system according to the present disclosure provides a worker state master that associates an image of a worker with a state of the worker, an image of equipment, and an article used by the worker. A definition database that stores an element work master that associates the combination of images with the element work that constitutes the work; a first history database that stores a history of the state of the worker and a history of the element work executed by the worker; A second history database that stores a history of equipment operating states, an equipment control unit, an image acquisition unit, a processing device, and a terminal are provided. The equipment control unit controls the equipment, acquires data on the operating status of the equipment, and stores the acquired data on the operating status in the second history database. The image acquisition unit acquires an image of a worker, equipment, and an article used by the worker. The processing device applies the image of the worker in the acquired image to the worker state master to specify the state of the worker, saves data indicating the specified state in the first history database, and acquires the acquired image. The image of the equipment and the article inside is applied to the element work master to identify the element work performed by the worker, and data indicating the identified element work is stored in the first history database. The terminal generates and outputs, based on the second history database and the first history database, information indicating the relationship between the operating state of the equipment and the state of the worker and information indicating the content of the element work.
　本開示における生産改善支援システムは、カメラで撮影した画像から作業者の作業者状態と作業者の実行した作業の要素作業とを求め、求めた作業者状態及び要素作業と設備の稼働状態とに基づいて、設備の稼働状態及び作業者の状態の関係を示す情報と、要素作業の内容を示す情報とを生成し、出力することができるため、作業者の負担を減らすとともに、分析を容易化することができる。 The production improvement support system in the present disclosure obtains the worker state of the worker and the element work of the work performed by the worker from the image captured by the camera, and determines the obtained worker state and the element work and the operating state of the equipment. Based on this, it is possible to generate and output information indicating the relationship between the operating state of the equipment and the state of the worker and information indicating the content of the elemental work, reducing the burden on the worker and facilitating the analysis. can do.

The length of the section of each work in the man-machine chart is determined based on the time calculated by the difference of the start date and time of each work. The items “preparation”, “jig replacement”, and “others” of the worker 3 shown in the man-machine chart are determined based on the worker state defined in the worker state master 510 described later. .. The “other” item of the worker 3 is a state of the worker 3 which is not defined in the worker state master 510, for example, the worker 3 is walking, and the worker 3 is not related to the facility 1. I am working on it. Further, the items “operating” and “stopping” of the equipment 1 shown in the man-machine chart are determined based on the equipment operating state code of the equipment operating state history 513. Note that, here, the codes other than the normal operation of the equipment operation status code 0000 are displayed as the item of “stop”.

　生産改善支援システム１００は、設備１の部位、物品２または作業者３の位置を判定することにより、作業者３の状態を示す作業者状態と作業者３の行う作業を構成する要素作業とを特定する。設備１の部位、物品２または作業者３の位置の判定は、カメラ６で撮影した画像に含まれる、設備１の部位、物品２または作業者３につけられたバーコードの位置を特定することにより行われる。このバーコードの位置を特定する処理について、以下に説明する。 The production improvement support system 100 determines the position of the facility 1, the position of the article 2 or the worker 3 to determine the worker state indicating the condition of the worker 3 and the component work constituting the work performed by the worker 3. Identify. The determination of the part of the equipment 1, the position of the article 2 or the worker 3 is performed by specifying the position of the part of the equipment 1, the bar code attached to the article 2 or the worker 3 included in the image captured by the camera 6. Done. The process of identifying the position of this barcode will be described below.
　バーコードの位置を特定する処理は、図２に示した処理装置７の作業者位置判定部７１０及び設備・物品位置判定部７２０で実行される。作業者位置判定部７１０または設備・物品位置判定部７２０は、カメラ６で撮影した画像を格子状に分割する。例えば、図８に示すように、横を７つ、縦を４つの格子状に分割する。この格子状に分割された画像を、画像分割マップ６４と呼ぶものとする。また、画像分割マップ６４における分割された画像のそれぞれを画像分割セル６４０と呼ぶものとする。画像分割セル６４０には、カメラ６から見て一番遠い左端をＡ１とし、順にＢ１、Ｃ１、Ｄ１、・・・、Ｇ４とする計２８個のセルが含まれている。このＡ１～Ｇ１までの各セルを、以下では、Ａ１セル、Ｂ１セル、Ｃ１セル等と呼ぶ。また、Ａ１セル、Ｂ１セル、Ｃ１セル等をセルの名称と呼ぶものとする。作業者位置判定部７１０または設備・物品位置判定部７２０では、設備１の部位、物品２または作業者３につけられたバーコードが、この画像分割セル６４０のどのセルにあるのかを検出することにより、物品２または作業者３の位置を判定する。 The process of identifying the position of the barcode is executed by the worker position determination unit 710 and the equipment/article position determination unit 720 of the processing device 7 shown in FIG. The worker position determination unit 710 or the equipment/article position determination unit 720 divides the image captured by the camera 6 into a grid pattern. For example, as shown in FIG. 8, the grid is divided into seven horizontal grids and four vertical grids. The image divided into the grid shape is referred to as an image division map 64. Further, each of the divided images in the image division map 64 will be referred to as an image division cell 640. The image division cell 640 includes a total of 28 cells in which the farthest left end when viewed from the camera 6 is A1, and B1, C1, D1,..., G4 in order. The cells A1 to G1 are hereinafter referred to as A1 cell, B1 cell, C1 cell and the like. Further, the A1 cell, the B1 cell, the C1 cell, and the like will be referred to as cell names. The worker position determination unit 710 or the equipment/article position determination unit 720 detects which cell of the image division cell 640 the bar code attached to the site of the equipment 1, the article 2 or the worker 3 is. , The position of the article 2 or the worker 3 is determined.
　ここで、具体例を用いて説明する。図９に示すのは、図１に示した第１カメラ６１の撮影領域である第１撮影領域６１０の画像である。この画像には、加工前ワーク置場１３と、設備１のワーク供給部１０と、作業者３と、作業者３が把持する物品２とが含まれている。ここでは、作業者３が把持する物品２の位置を判定するものとする。 ▽Here, we will explain using a concrete example. FIG. 9 shows an image of the first shooting area 610 which is the shooting area of the first camera 61 shown in FIG. This image includes the unprocessed work storage area 13, the work supply unit 10 of the facility 1, the worker 3, and the article 2 held by the worker 3. Here, the position of the article 2 gripped by the worker 3 is determined.
　図２に示した処理装置７の設備・物品位置判定部７２０は、この第１撮影領域６１０の画像を、例えば、横を７つ、縦を４つの格子状に分割し、画像分割マップ６４を生成する。画像分割セル６４０には、図９に示すように、第１カメラ６１から見て一番遠い左端をＡ１とし、順にＢ１、Ｃ１、Ｄ１、・・・、Ｇ４とする計２８個のセルが含まれている。 The equipment/article position determination unit 720 of the processing device 7 shown in FIG. 2 divides the image of the first imaging region 610 into, for example, seven horizontal grids and four vertical grids, and creates an image partition map 64. To generate. As shown in FIG. 9, the image division cell 640 includes a total of 28 cells in which the farthest left end when viewed from the first camera 61 is A1, and B1, C1, D1,..., G4 in order. Has been.
　設備・物品位置判定部７２０は、Ａ１セルを検索対象セルの初期セルとして設定し、バーコードの有無を判定する。バーコードがあった場合、セルの位置とバーコードから読み取った英数字、記号等とを図３に示す処理装置７のメモリ７３１に一時的に保存する。このメモリ７３１に一時的に保存されたセルの位置と読み取った英数字、記号等は、図２に示した処理装置７の処理に用いられ、最終的にサーバ５のデータ記憶部５１内のデータベースに保存される。また、バーコードが無ければ、検索対象セルを次のＢ１セルに移動し、バーコードの有無を判定する。この判定を、Ｃ１、Ｄ１、・・・、Ｇ４セルまでを順番に各セルに対して行い、バーコードの有無を判定する。 The equipment/article position determination unit 720 sets the A1 cell as the initial cell of the search target cell and determines the presence or absence of the barcode. If there is a bar code, the position of the cell and the alphanumeric characters, symbols, etc. read from the bar code are temporarily stored in the memory 731 of the processing device 7 shown in FIG. The position of the cell temporarily stored in the memory 731 and the read alphanumeric characters, symbols and the like are used for the processing of the processing device 7 shown in FIG. 2 and finally the database in the data storage unit 51 of the server 5. Stored in. If there is no bar code, the search target cell is moved to the next B1 cell and the presence or absence of the bar code is determined. This determination is performed for each cell in order from C1, D1,..., G4 cells to determine the presence or absence of a barcode.
　図９においては、物品２はＤ３セルに有る。このため、設備・物品位置判定部７２０は、物品２につけられたバーコードを、Ｄ３セルにあるものと判定する。そして、設備・物品位置判定部７２０は、このＤ３セルを物品２が有るセルの位置として、処理装置７のメモリ７３１に保存する。 In FIG. 9, the article 2 is in the D3 cell. Therefore, the equipment/article position determination unit 720 determines that the barcode attached to the article 2 is in the D3 cell. Then, the equipment/article position determination unit 720 stores this D3 cell in the memory 731 of the processing device 7 as the position of the cell in which the article 2 is located.
　次に、図１に示したサーバ５のデータ記憶部５１内に保存されるデータベースのデータテーブルについて、図１０Ａから図１０Ｆに示す。データ記憶部５１内に保存されるデータベースは、作業者３の画像とその作業者３の状態とを対応付けて定義した作業者状態マスタ５１０と、設備１で作業する作業者３の一覧である作業者マスタ５１１と、作業者３の作業の履歴を示す履歴データを保存した作業者状態履歴５１２と、設備１の稼働状態のデータを保存する設備稼働状態履歴５１３と、設備１の画像と作業者３が使用している物品２の画像の組み合わせと作業者３の実行した作業における要素作業のデータを定義した要素作業マスタ５１４と、要素作業に用いられる物品２又は設備１の部位を定義した設備・物品マスタ５１６と、作業者３による要素作業の履歴である要素作業履歴５１７とである。 Next, FIGS. 10A to 10F show the data tables of the database stored in the data storage unit 51 of the server 5 shown in FIG. The database stored in the data storage unit 51 is a worker state master 510 that defines the image of the worker 3 and the state of the worker 3 in association with each other, and a list of the workers 3 who work on the facility 1. A worker master 511, a worker state history 512 that stores history data indicating a history of work performed by the worker 3, a facility operating state history 513 that stores data on the operating state of the facility 1, an image of the facility 1 and work The element work master 514 defining the combination of the images of the article 2 used by the person 3 and the data of the element work in the work performed by the worker 3, and the part of the article 2 or the facility 1 used for the element work are defined. An equipment/article master 516 and an element work history 517 which is a history of element work by the worker 3.
　図１０Ａに、作業者状態マスタ５１０に含まれるデータテーブルを示す。作業者状態マスタ５１０のデータテーブルには、作業者３の作業者状態を示す作業者状態ＩＤと、作業者３の作業者状態の名称を示す作業者状態名称と、作業者３に付けられたバーコードの位置を示す作業者バーコード位置と、前回の作業者状態ＩＤと、設備１の稼働状態を示す設備稼働状態コードとを含む。この作業者状態ＩＤには、作業者３の各作業者状態についてユニークな番号、英数字と記号とを組み合わせたコード等が定義される。また、作業者状態名称には、作業者３の各作業者状態についてユニークな名称が定義される。この作業者状態ＩＤと作業者状態名称とは、全ての作業者３で同じものを用いる。例えば、図１０Ａに示すように、作業者状態ＩＤが１００１１の場合、作業者状態名称はワーク供給準備と定義する。 FIG. 10A shows a data table included in the worker status master 510. In the data table of the worker state master 510, the worker state ID indicating the worker state of the worker 3, the worker state name indicating the name of the worker state of the worker 3, and the worker 3 are attached. It includes a worker bar code position indicating the position of the bar code, a previous worker status ID, and an equipment operation status code indicating the operation status of the equipment 1. In this worker state ID, a unique number for each worker state of the worker 3 or a code combining alphanumeric characters and symbols is defined. In addition, a unique name for each worker state of the worker 3 is defined as the worker state name. The same worker state ID and worker state name are used by all the workers 3. For example, as shown in FIG. 10A, when the worker state ID is 10011, the worker state name is defined as work supply preparation.
　作業者バーコード位置には、各作業者状態における作業者３の位置を判定するための基準となるバーコードの位置が定義される。この作業者バーコード位置は、バーコードの位置を判定するための画像が第１カメラ６１、第２カメラ６２、第３カメラ６３の何れのカメラで撮影されたのかを示す番号と、画像分割マップ６４内のセルの名称とが定義されている。例えば、図１０Ａに示すように、作業者状態ＩＤが１００１１で、作業者状態名称がワーク供給準備中の場合、「１－Ｃ２」と定義されている。これは、第１カメラ６１で撮影された画像のＣ２セルに作業者３に付けられたバーコードがあることを意味している。 The position of the barcode, which is a reference for determining the position of the worker 3 in each worker state, is defined in the worker barcode position. The worker bar code position is a number indicating which camera of the first camera 61, the second camera 62, and the third camera 63 has taken the image for determining the bar code position, and the image division map. The names of the cells in 64 are defined. For example, as shown in FIG. 10A, when the worker state ID is 10011 and the worker state name is "work preparation ready", it is defined as "1-C2". This means that there is a bar code attached to the worker 3 in the C2 cell of the image taken by the first camera 61.
　前回の作業者状態ＩＤには、この作業者状態の直前に行われるべき作業者状態を示す作業者状態ＩＤが定義される。なお、直前に行われるべき作業者状態が無い場合には、ブランクを示す「－」が定義される。例えば、図１０Ａに示すように、作業者状態ＩＤが１００１１で、作業者状態名称がワーク供給準備の場合、直前に行われるべき作業者状態が無いため、ブランクを示す「－」が定義される。また、作業者状態ＩＤが１００１２で、作業者状態名称がワーク供給の場合、直前に行われるべき作業者状態は、ワーク供給準備である。このため、ワーク供給準備を示す作業者状態ＩＤの１００１１が、前回の作業者状態ＩＤに定義される。 The previous worker state ID defines a worker state ID indicating the worker state that should be performed immediately before this worker state. If there is no worker state to be performed immediately before, "-" indicating a blank is defined. For example, as shown in FIG. 10A, when the worker state ID is 10011 and the worker state name is “work supply preparation”, there is no worker state to be performed immediately before, so “−” indicating a blank is defined. .. When the worker state ID is 10012 and the worker state name is work supply, the worker state to be performed immediately before is work supply preparation. Therefore, the worker state ID 10011 indicating the work supply preparation is defined as the previous worker state ID.
　設備稼働状態コードは、各作業者状態中における設備１の稼働状態を示すコードであり、図１に示した設備１の設備制御部４から送信される信号に基づいて定義される。このコードには、設備１の稼働状態に応じてユニークなコードが割り当てられる。設備稼働状態コードは、例えば、正常稼働を示す００００、処理するワークの搬入を待つワーク待ちを示す０００１、チャック異常を示す０００２、加工治具の使用回数の上限超過を示す０００３、加工治具の交換を示す０００４等である。 The equipment operating state code is a code indicating the operating state of the equipment 1 during each worker state, and is defined based on the signal transmitted from the equipment control unit 4 of the equipment 1 shown in FIG. A unique code is assigned to this code according to the operating state of the equipment 1. The equipment operation status code is, for example, 0000 indicating normal operation, 0001 indicating waiting for a workpiece to wait for a workpiece to be processed, 0002 indicating a chuck error, 0003 indicating that the number of times the machining jig has been used exceeds the upper limit, For example, 0004 indicating exchange.
　また、この作業者状態マスタ５１０は、作業者３ごとに作成される。これは、各作業者３の腕の長さ、身長等の体型により、付けられるバーコードの位置が異なる場合があるため、同じ作業者状態マスタ５１０を用いると作業者３の作業者状態が判定できない場合があるからである。 Further, this worker status master 510 is created for each worker 3. This is because the position of the attached barcode may be different depending on the body length such as the arm length and height of each worker 3, so that the worker state of the worker 3 is determined by using the same worker state master 510. This is because there are cases where it cannot be done.
　図１０Ｂに、作業者マスタ５１１のデータテーブルを示す。この作業者マスタ５１１は、設備１で作業を行う作業者３の一覧を定義したものである。作業者マスタ５１１には、各作業者３の作業者ＩＤと作業者名称とが含まれる。作業者ＩＤは各作業者３で固有のコードが定義される。このコードは、例えば、英数字、記号、図形等を組み合わせたものある。また、作業者名称は、各作業者３の氏名、イニシャル等の固有名称が定義される。 FIG. 10B shows a data table of the worker master 511. The worker master 511 defines a list of workers 3 who work on the facility 1. The worker master 511 includes the worker ID and the worker name of each worker 3. A unique code is defined for each worker 3 as the worker ID. This code is, for example, a combination of alphanumeric characters, symbols and figures. Further, as the worker name, a proper name such as the name and initials of each worker 3 is defined.
　図１０Ｃに、作業者状態履歴５１２のデータテーブルを示す。作業者状態履歴５１２のデータテーブルは、作業者３の作業履歴をまとめたデータテーブルである。この作業者状態履歴５１２のデータテーブルは、作業者３ごとに作成される。作業者状態履歴５１２のデータテーブルには、作業者３により作業が開始された日時である開始日時と、作業者３に付けられたバーコードの位置を示す作業者バーコード位置と、直前の作業者３の作業者状態ＩＤを示す前回の作業者状態ＩＤと、設備１の稼働状態を示す設備稼働状態コードと、作業者３の作業の状態を示す作業者状態ＩＤとを含む。 FIG. 10C shows a data table of the worker status history 512. The data table of the worker status history 512 is a data table that summarizes the work history of the worker 3. The data table of the worker status history 512 is created for each worker 3. In the data table of the worker state history 512, the start date and time when the work is started by the worker 3, the worker barcode position indicating the position of the barcode attached to the worker 3, and the immediately preceding work. It includes a previous worker state ID indicating the worker state ID of the worker 3, a facility operating state code indicating the operating state of the facility 1, and a worker state ID indicating the working state of the worker 3.
　開始日時は、図１に示した設備制御部４により検知された設備１の稼働開始日時が入力される。作業者バーコード位置は、バーコードの位置を判定するための画像が第１カメラ６１、第２カメラ６２、第３カメラ６３の何れのカメラで撮影されたのかを示す番号と、画像分割マップ６４内のセルの名称とが入力される。作業者状態ＩＤには、直前の作業者３の作業者状態ＩＤが入力される。なお、直前の作業者状態ＩＤが無い場合には、ブランクを示す「－」が入力される。 As the start date and time, the operation start date and time of the equipment 1 detected by the equipment control unit 4 shown in FIG. 1 is input. The worker bar code position is a number indicating which camera of the first camera 61, the second camera 62, and the third camera 63 has taken the image for determining the bar code position, and the image division map 64. The name of the cell in is input. The worker state ID of the worker 3 immediately before is input to the worker state ID. If there is no immediately preceding worker state ID, "-" indicating blank is input.
　設備稼働状態コードには、図１に示した設備制御部４から送信される信号に対応する設備１の稼働状態を示すコードが入力される。作業者状態ＩＤには、現在の作業者バーコード位置と、前回の作業者状態ＩＤと、設備稼働状態コードを、図１０Ａの作業者状態マスタ５１０のデータテーブルと比較し、一致した列の作業者状態ＩＤが入力される。なお、作業者３の作業者状態が作業者状態マスタ５１０に定義されていない状態である場合、作業者状態ＩＤにはブランクを示す「－」が入力される。この作業者状態マスタ５１０に定義されていない状態とは、例えば、作業者３が歩行中、作業者３が設備１とは関連しない作業をしている等の状態である。 As the equipment operation status code, a code indicating the operation status of the equipment 1 corresponding to the signal transmitted from the equipment control unit 4 shown in FIG. 1 is input. For the worker status ID, the current worker barcode position, the previous worker status ID, and the equipment operation status code are compared with the data table of the worker status master 510 in FIG.

Note that, here, n is a natural number of 1 or more.
　この要素作業ＩＤには、作業者３の行う作業における各要素作業についてユニークな番号、英数字を組み合わせたコード等が定義される。また、要素作業名称には、各要素作業についてユニークな名称が定義される。この要素作業ＩＤと要素作業名称とは、全ての作業者３で同じものを用いる。例えば、図１０Ｅに示すように、要素作業ＩＤ２００１１の場合、要素作業名称は加工部扉開である。 The element work ID defines a unique number for each element work in the work performed by the worker 3, a code combining alphanumeric characters, and the like. A unique name is defined for each element work as the element work name. The same element work ID and element work name are used by all operators 3. For example, as shown in FIG. 10E, in the case of the element work ID 20011, the element work name is the processing unit door open.
　バーコード位置は、設備１の部位またはｎ個の物品２それぞれに付けられたバーコードの位置を示す、基準となるバーコードの位置が定義される。このバーコード位置は、バーコードの位置を判定するための画像が第１カメラ６１、第２カメラ６２、第３カメラ６３の何れのカメラで撮影されたのかを示す番号と、画像分割マップ６４内のセルの名称とが定義されている。例えば、図１０Ｅに示すように、要素作業ＩＤが２００１１で、要素作業名称が加工部扉開の場合、「２－Ｅ３」と定義されている。 The barcode position is defined as a reference barcode position that indicates the position of the barcode attached to each part of the facility 1 or each of the n articles 2.

If there is no element work to be performed immediately before, "-" indicating a blank is defined. For example, as shown in FIG. 10E, when the element work ID is 20011 and the element work name is the opening of the processing section door, there is no element work to be performed immediately before, and thus “-” indicating a blank is defined. Further, when the element work ID is 20013 and the element work name is jig removal, the element work to be performed immediately before is to open the processing section door. Therefore, the element work ID 20011 indicating that the processing section door is opened is defined as the previous element work ID.
　この要素作業マスタ５１４のデータテーブルは、作業者３ごとに作成される。これは、各作業者３の腕の長さ、身長等の体型により物品２を把持した位置が異なる場合があるため、同じ要素作業マスタ５１４を用いると物品２の位置が判定できない場合があるからである。 The data table of the element work master 514 is created for each worker 3.

　次に、生産改善支援システム１００の動作について、図１１から図１６に示したフローチャートを参照しつつ説明する。図１１には、生産改善支援システム１００の動作処理が示されている。生産改善支援システム１００では、図１に示した設備１の設備制御部４と、サーバ５と、処理装置７と、端末９とが協同して動いている。この生産改善支援システム１００の動作処理は、設備制御部４と、サーバ５と、処理装置７と、端末９とのそれぞれで動作する各プログラムにより構成されたプログラムである。この生産改善支援システム１００の動作処理のプログラムは、生産改善支援システム１００の起動時に設備制御部４と、サーバ５と、処理装置７と、端末９とのそれぞれで動作するプログラムが起動し、実行することにより動作するものである。 Next, the operation of the production improvement support system 100 will be described with reference to the flowcharts shown in FIGS. 11 to 16. FIG. 11 shows the operation processing of the production improvement support system 100. In the production improvement support system 100, the equipment control unit 4 of the equipment 1 shown in FIG. 1, the server 5, the processing device 7, and the terminal 9 operate in cooperation. The operation process of the production improvement support system 100 is a program configured by each program that operates in each of the equipment control unit 4, the server 5, the processing device 7, and the terminal 9. This operation processing program of the production improvement support system 100 starts and executes a program that operates in each of the equipment control unit 4, the server 5, the processing device 7, and the terminal 9 when the production improvement support system 100 is started. It operates by doing.
　まず、設備制御部４は、設備１の稼働情報を取得し、サーバ５へ送信する（ステップＳ１０１）。サーバ５は、設備制御部４から設備１の稼働情報を受信すると、データ記憶部５１内のデータベースに保存する（ステップＳ１０２）。 First, the equipment control unit 4 acquires the operation information of the equipment 1 and sends it to the server 5 (step S101). When the server 5 receives the operation information of the equipment 1 from the equipment control unit 4, the server 5 stores the operation information in the database in the data storage unit 51 (step S102).
　処理装置７は、カメラ６から設備１及び作業者３を含む画像を取得する（ステップＳ１０３）。処理装置７は、取得した画像から作業者状態を判定する（ステップＳ１０４）。この処理装置７による作業者状態の判定を、図１２に示した作業者状態判定処理のフローチャートを参照しつつ、以下に説明する。 The processing device 7 acquires an image including the equipment 1 and the worker 3 from the camera 6 (step S103). The processing device 7 determines the worker state from the acquired image (step S104). The determination of the worker state by the processing device 7 will be described below with reference to the flowchart of the worker state determination process shown in FIG.
　この作業者状態判定処理は、図２に示した処理装置７の作業者状態判定機能部７１として実行されるプログラムである。まず、作業者状態判定機能部７１の作業者位置判定部７１０は、カメラ６から取得した画像からバーコードを検出するために、位置判定処理を実行する（ステップＳ２０１）。この位置判定処理については、図１３に示すフローチャートを参照しつつ、以下に説明する。 This worker state determination processing is a program executed as the worker state determination function unit 71 of the processing device 7 shown in FIG. First, the worker position determination unit 710 of the worker state determination function unit 71 executes a position determination process in order to detect a barcode from the image acquired from the camera 6 (step S201). This position determination processing will be described below with reference to the flowchart shown in FIG.
　作業者状態判定機能部７１の作業者位置判定部７１０は、カメラ６から取得した画像を格子状に分割して図８に示した画像分割マップ６４を生成する（ステップＳ３０１）。作業者位置判定部７１０は、画像分割マップ６４の画像分割セルのうち検索対象セルの初期セルを設定する（ステップＳ３０２）。ここでは、検索対象セルの初期セルを、例えば、図８に示すＡ１セルとする。作業者位置判定部７１０は、検索対象セル内に作業者３につけられたバーコードがあるか否かを判定する（ステップＳ３０３）。 The worker position determination unit 710 of the worker state determination function unit 71 divides the image acquired from the camera 6 into a grid shape to generate the image division map 64 shown in FIG. 8 (step S301). The worker position determination unit 710 sets the initial cell of the search target cell among the image division cells of the image division map 64 (step S302). Here, the initial cell of the search target cell is, for example, the A1 cell shown in FIG. The worker position determination unit 710 determines whether or not there is a barcode attached to the worker 3 in the search target cell (step S303).
　検索対象セル内にバーコードが存在する場合（ステップＳ３０３；ＹＥＳ）、セルの位置とバーコードから読み取った英数字、記号等とを、図３に示す処理装置７のメモリ７３１に一時的に保存する（ステップＳ３０４）。検索対象セル内にバーコードが存在しない場合（ステップＳ３０３；ＮＯ）、作業者位置判定部７１０は、次の検索対象セルとなるセルが画像分割マップ６４上に無いか判定する（ステップＳ３０５）。 When the barcode exists in the search target cell (step S303; YES), the position of the cell and the alphanumeric characters and symbols read from the barcode are temporarily stored in the memory 731 of the processing device 7 shown in FIG. (Step S304). When the barcode does not exist in the search target cell (step S303; NO), the worker position determination unit 710 determines whether or not the cell to be the next search target cell is on the image division map 64 (step S305).
　検索対象セルとなるセルが無い場合（ステップＳ３０５；ＹＥＳ）、作業者位置判定部７１０は位置判定処理を終了する。また、検索対象セルとなるセルがある場合（ステップＳ３０５；ＮＯ）、作業者位置判定部７１０は、画像分割マップ６４上の次のセルの位置に検索対象セルを移動する（ステップＳ３０６）。例えば、図８に示した画像分割マップ６４のＡ１セルからＢ１セルに検索対象セルを移動させ（ステップＳ３０６）、前出のステップＳ３０３からステップＳ３０５を繰り返す。 If there is no cell to be searched (step S305; YES), the worker position determination unit 710 ends the position determination process. If there is a cell to be searched (step S305; NO), the worker position determination unit 710 moves the search target cell to the position of the next cell on the image division map 64 (step S306). For example, the search target cell is moved from the A1 cell to the B1 cell of the image division map 64 shown in FIG. 8 (step S306), and steps S303 to S305 described above are repeated.
　図１２の作業者状態判定処理に戻る。作業者位置判定部７１０は、図３に示す処理装置７のメモリ７３１にセルの位置とバーコードから読み取った英数字、記号等とが保存されているか判定する（ステップＳ２０２）。メモリ７３１に保存されている場合（ステップＳ２０２；ＹＥＳ）、作業者位置判定部７１０は、メモリ７３１に保存されたバーコードに含まれる英数字、図形、記号等と、図１０Ｂに示す作業者マスタ５１１に定義された作業者ＩＤとを比較し、バーコードに含まれる英数字、図形、記号等に一致する作業者３が居るか否かを判定する（ステップＳ２０３）。また、作業者位置判定部７１０は、メモリ７３１にセルの位置とバーコードから読み取った英数字、記号等とが保存されていなかった場合、作業者状態判定処理を終了する（ステップＳ２０２；ＮＯ）。 Return to the worker status determination process in FIG. The worker position determination unit 710 determines whether the cell position and the alphanumeric characters, symbols, etc. read from the barcode are stored in the memory 731 of the processing device 7 shown in FIG. 3 (step S202). When it is stored in the memory 731 (step S202; YES), the worker position determination unit 710 determines that the alphanumeric characters, figures, symbols, etc. included in the barcode stored in the memory 731 and the worker master shown in FIG. 10B. The worker ID defined in 511 is compared to determine whether or not there is a worker 3 who matches the alphanumeric characters, figures, symbols, etc. included in the barcode (step S203). Further, the worker position determination unit 710 ends the worker state determination processing when the cell position and the alphanumeric characters, symbols, etc. read from the barcode are not stored in the memory 731 (step S202; NO). ..
　作業者位置判定部７１０は、一致する作業者３が居た場合（ステップＳ２０３；ＹＥＳ）、バーコードの位置を現在の作業者３の位置として判定する。作業者位置判定部７１０は、判定した結果を、作業者位置変化判定部７１１に入力する。また、作業者位置判定部７１０は、一致する作業者３が無かった場合（ステップＳ２０３；ＮＯ）、作業者状態判定処理を終了する。 When there is a matching worker 3 (step S203; YES), the worker position determination unit 710 determines the position of the barcode as the current position of the worker 3. The worker position determination unit 710 inputs the determination result to the worker position change determination unit 711. Further, when there is no matching worker 3 (step S203; NO), the worker position determination unit 710 ends the worker state determination processing.
　作業者位置変化判定部７１１は、サーバ５のデータ記憶部５１内に保存されたデータベースから、現在の作業者３の作業者状態履歴５１２を取得する。作業者位置変化判定部７１１は、取得した作業者状態履歴５１２から、作業者３の前回の作業者位置を取得する。作業者位置変化判定部７１１は、取得した作業者３の前回の作業者位置と、作業者位置変化判定部７１１から入力された現在の作業者３の位置とに基づいて、作業者３の位置変化を判定する。作業者位置変化判定部７１１は、判定した結果を作業者状態判定部７１３に入力する（ステップＳ２０４）。 The worker position change determination unit 711 acquires the worker state history 512 of the current worker 3 from the database stored in the data storage unit 51 of the server 5. The worker position change determination unit 711 acquires the previous worker position of the worker 3 from the acquired worker state history 512. The worker position change determination unit 711 determines the position of the worker 3 based on the acquired previous worker position of the worker 3 and the current position of the worker 3 input from the worker position change determination unit 711. Determine changes. The worker position change determination unit 711 inputs the determination result to the worker state determination unit 713 (step S204).
　設備稼働状態判定部７１２は、サーバ５のデータ記憶部５１内に保存された設備稼働状態履歴５１３から、設備１の稼働状態を取得する。設備稼働状態判定部７１２は、取得した設備１の稼働状態に基づいて、設備１の現在の稼働状態を判定する。設備稼働状態判定部７１２は、判定した結果を作業者状態判定部７１３に入力する（ステップＳ２０５）。 The equipment operating state determination unit 712 acquires the operating state of the equipment 1 from the equipment operating state history 513 stored in the data storage unit 51 of the server 5. The equipment operating status determination unit 712 determines the current operating status of the equipment 1 based on the acquired operating status of the equipment 1. The equipment operating state determination unit 712 inputs the determined result to the worker state determination unit 713 (step S205).
　作業者状態判定部７１３は、作業者位置変化判定部７１１から入力された作業者３の位置変化の判定結果と設備稼働状態判定部７１２から入力された設備１の稼働状態の判定結果とを、サーバ５のデータ記憶部５１に保存された作業者状態マスタ５１０と照合し、作業者３の作業者状態を判定する（ステップＳ２０６）。作業者状態判定部７１３は、判定した判定結果を、作業者状態履歴５１２の末尾に追記し、サーバ５に保存する（ステップＳ２０７）。 The worker state determination unit 713 uses the determination result of the position change of the worker 3 input from the worker position change determination unit 711 and the determination result of the operating state of the equipment 1 input from the equipment operating state determination unit 712. The worker state master 510 stored in the data storage unit 51 of the server 5 is collated to determine the worker state of the worker 3 (step S206). The worker state determination unit 713 adds the determined determination result to the end of the worker state history 512 and stores it in the server 5 (step S207).
　ここで、図１１に戻る。処理装置７は、取得した画像から設備１または物品２における要素作業を判定する（ステップＳ１０５）。この処理装置７による要素作業の判定を、図１４に示した要素作業判定処理のフローチャートを参照しつつ、以下に説明する。 Now, return to FIG. 11.

The equipment/article position determination unit 720 inputs the determination result to the equipment/article position change determination unit 721. In addition, the equipment/article position determination unit 720 ends the element work determination processing when there is no matching part of the equipment 1 or the article 2 (step S403; NO).

　以上のように、実施の形態１によれば、生産改善支援システム１００は、カメラ６で撮影した画像から作業者３の作業者状態、作業者３の行う作業における要素作業を求め、サーバ５のデータ記憶部５１内のデータベースに保存することができる。これにより、作業者３の作業者状態に関するデータと、作業者の行う作業おける要素作業に関するデータとを自動収集することができる。このため、作業者３の負担を軽減することができる。 As described above, according to the first embodiment, the production improvement support system 100 obtains the worker state of the worker 3 and the element work in the work performed by the worker 3 from the image captured by the camera 6, and It can be stored in a database in the data storage unit 51. As a result, it is possible to automatically collect the data regarding the worker state of the worker 3 and the data regarding the element work in the work performed by the worker. Therefore, the burden on the worker 3 can be reduced.
　また、生産改善支援システム１００は、サーバ５のデータ記憶部５１内のデータベースに保存した作業者３の作業者状態履歴５１２、設備１の設備稼働状態履歴５１３、作業者３の行う作業における要素作業履歴５１７のデータを基にして、マンマシンチャートまたは要素作業タイムチャートを生成し、端末９の表示装置９１に表示することができる。これにより、設備１の管理者または設備１のデータを分析する分析者は、設備１の稼働状態と作業者３の作業者状態を連合させて把握することができる。そして、設備１の管理者または設備１のデータを分析する分析者は、マンマシンチャートまたは要素作業タイムチャートに基づいて、各作業者３または各要素作業の違いを分析することができる。このため、設備１の管理者または設備１のデータを分析する分析者は、短期間で改善活動を進めることができる。したがって、生産改善支援システム１００は、分析を容易化することができる。 In addition, the production improvement support system 100 includes the worker state history 512 of the worker 3, the facility operating state history 513 of the facility 1, and the elemental work in the work performed by the worker 3 stored in the database in the data storage unit 51 of the server 5. Based on the data of the history 517, a man-machine chart or element work time chart can be generated and displayed on the display device 91 of the terminal 9. As a result, the manager of the equipment 1 or an analyst who analyzes the data of the equipment 1 can understand the operating state of the equipment 1 and the worker state of the worker 3 in association with each other. Then, the manager of the facility 1 or an analyst who analyzes the data of the facility 1 can analyze the difference between each worker 3 or each component work based on the man-machine chart or the component work time chart. Therefore, the manager of the equipment 1 or the analyst who analyzes the data of the equipment 1 can proceed with the improvement activity in a short period of time. Therefore, the production improvement support system 100 can facilitate the analysis.
　さらに、生産改善支援システム１００では、マンマシンチャートまたは要素作業タイムチャートにより、設備１または作業者３の実績データを、設備１の管理者が容易に把握することができる。このため、生産改善支援システム１００は、設備１および作業者３のリソースの評価をサポートすることができる。 Further, in the production improvement support system 100, the man-machine chart or the element work time chart allows the manager of the equipment 1 to easily grasp the actual data of the equipment 1 or the worker 3. Therefore, the production improvement support system 100 can support the evaluation of the resources of the equipment 1 and the worker 3.
（実施の形態２）
　上記の実施の形態１において、図１に示した生産改善支援システム１００は、図５に示したマンマシンチャートと図６に示した要素作業タイムチャートとを、それぞれ独立したデータをもとに生成し、端末９の表示装置９１に表示させるものとした。しかし、この場合、設備１の管理者、設備１のデータを分析する分析者等は、目視でマンマシンチャートの作業者状態を確認し、例えば、作業時間が長すぎる、作業の順番が違う等の問題の有無を判断することになる。そして、設備１の管理者、分析者等は、問題のある箇所を見つけた場合、その期間に対する要素作業タイムチャートを手動で生成し、表示装置９１に表示させる。このため、設備１の管理者、分析者等の作業負担が大きい。そこで、本実施の形態２では、生成したマンマシンチャートのうち、作業時間が長すぎる、作業の順番が違う等の問題が生じている作業者状態の期間に対応する要素作業タイムチャートを表示できるようにする。 (Embodiment 2)
In Embodiment 1 described above, the production improvement support system 100 shown in FIG. 1 generates the man-machine chart shown in FIG. 5 and the element work time chart shown in FIG. 6 based on independent data. Then, the display device 91 of the terminal 9 is made to display. However, in this case, the manager of the equipment 1, the analyst who analyzes the data of the equipment 1, and the like visually confirms the operator state of the man-machine chart, and, for example, the working time is too long, the work order is different, etc. The problem will be judged. Then, when a manager, an analyst, or the like of the equipment 1 finds a problematic portion, it manually generates an element work time chart for the period and displays it on the display device 91. For this reason, the work load on the manager of the facility 1, the analyst, etc. is heavy. Therefore, in the second embodiment, among the generated man-machine charts, the element work time chart corresponding to the period of the worker state in which the work time is too long, the work order is out of order, and the like can be displayed. To do so.
　図１７に、本実施の形態２におけるマンマシンチャートと要素作業タイムチャートとの表示の一例を示す。まず、マンマシンチャートの各作業者状態に対して、予め作業時間を設定しておく。設定される作業時間は、その作業を複数の作業者３が行った際の平均の時間、設備１の管理者により定められた時間等である。 FIG. 17 shows an example of the display of the man-machine chart and element work time chart in the second embodiment. First, a working time is set in advance for each worker state on the man-machine chart. The set work time is an average time when a plurality of workers 3 perform the work, a time set by the manager of the equipment 1, and the like.
　生産改善支援システム１００は、予め設定された作業時間を超過した作業者状態がある場合、その作業者状態の区間の色を、作業時間を超過していない作業者状態の区間とは異なる色に設定する。続いて、生産改善支援システム１００は、マンマシンチャートを表示装置９１に表示させる。例えば、図１７に示すマンマシンチャートの項目「治具交換」が、予め設定された作業時間を超過した作業者状態であるものとする。この場合、生産改善支援システム１００は、治具交換を示す区間Ｔ１０１の色に、他の区間との色と異なる色を設定する。 When there is a worker state that exceeds the preset work time, the production improvement support system 100 changes the color of the section of the worker state to a color different from the color of the worker state section that does not exceed the work time. Set. Then, the production improvement support system 100 displays the man-machine chart on the display device 91. For example, it is assumed that the item “jig replacement” in the man-machine chart shown in FIG. 17 is a worker state that exceeds a preset work time. In this case, the production improvement support system 100 sets the color of the section T101 indicating the jig replacement to a color different from the colors of the other sections.
　続いて、生産改善支援システム１００は、マンマシンチャートの治具交換に対応する期間の要素作業タイムチャートを生成し、表示装置９１に表示させる。具体的には、区間Ｔ１０１に対応する期間の要素作業タイムチャートを生成し、表示装置９１に表示させる。なお、生産改善支援システム１００は、要素作業タイムチャートを生成する際、その要素作業タイムチャートのうち、最も作業に時間が掛かった要素作業の区間の色に他の要素作業の区間の色と異なる色を設定する。例えば、図１７に示す要素作業タイムチャートにおいて、作業者３は、要素作業の項目「治具取り付け」に、最も時間がかかったものとする。この場合、生産改善支援システム１００は、治具取り付けを示す区間Ｔ１０２の色に、他の区間とは異なる色を設定する。なお、マンマシンチャートにおいて、予め設定された作業時間を超過した作業者状態が複数ある場合、各作業者状態に対応する要素作業タイムチャートを全て、または、特定の要素作業タイムチャートを選択して表示できるようにしてもよい。 Next, the production improvement support system 100 generates an element work time chart for the period corresponding to the jig replacement of the man-machine chart, and displays it on the display device 91. Specifically, the element work time chart for the period corresponding to the section T101 is generated and displayed on the display device 91. When the production improvement support system 100 generates the element work time chart, the color of the section of the element work that took the longest time in the element work time chart differs from the color of the section of the other element work. Set the color. For example, in the element work time chart shown in FIG. 17, it is assumed that the worker 3 took the longest time to perform the item “fix jig” of the element work. In this case, the production improvement support system 100 sets the color of the section T102 indicating jig attachment to a color different from the other sections. In the man-machine chart, when there are multiple worker states that exceed the preset work time, select all element work time charts corresponding to each worker state or select a specific element work time chart. You may be able to display.
　本実施の形態２に係るマンマシンチャートの表示は、図１５に示したマンマシンチャート表示処理により行うことができる。具体的には、マンマシンチャート表示処理のフローチャートのステップＳ５０２において、図４に示したマンマシンチャート生成部９２３は、予め設定された作業時間を超過した作業者状態がある場合、その作業者状態の区間の色を、作業時間を超過していない作業者状態の区間とは異なる色に設定する。 The display of the man-machine chart according to the second embodiment can be performed by the man-machine chart display processing shown in FIG. Specifically, in step S502 of the flowchart of the man-machine chart display process, the man-machine chart generation unit 923 shown in FIG. 4 determines that if there is a worker state that exceeds the preset work time, that worker state. The color of the section is set to be different from the color of the section in the worker state where the work time is not exceeded.
　また、本実施の形態２に係る要素作業タイムチャートの表示は、図１６に示した要素作業タイムチャート表示処理により行うことができる。具体的には、要素作業タイムチャート表示処理のフローチャートのステップＳ６０２において、図４に示した要素作業タイムチャート生成部９２５は、最も作業に時間のかかった要素作業の区間の色を、他の要素作業の区間の色と異なる色に設定する。 The display of the element work time chart according to the second embodiment can be performed by the element work time chart display processing shown in FIG. Specifically, in step S602 of the flowchart of the element work time chart display process, the element work time chart generation unit 925 illustrated in FIG. 4 sets the color of the section of the element work that took the longest time to other elements. Set a color different from the color of the work section.
　以上のように、実施の形態２によれば、予め設定された作業時間を超過した作業者状態を示す区間の色を変化させたタイムチャート、および、タイムチャートの色を変化させた作業者状態の区間に対応する要素作業タイムチャートを端末９の表示装置９１に表示させることできる。これにより、設備１の管理者、分析者等は、時間の掛かっている原因を容易に把握することができ、短期間で改善活動を進めることができる。 As described above, according to the second embodiment, the time chart in which the color of the section indicating the worker state in which the preset work time has been exceeded is changed, and the worker state in which the color of the time chart is changed The element work time chart corresponding to the section can be displayed on the display device 91 of the terminal 9. As a result, the manager of the equipment 1, the analyst, etc. can easily grasp the cause of the time consuming and can proceed with the improvement activity in a short period of time.
（実施の形態３）
　上記の実施の形態１および２では、図１に示した生産改善支援システム１００は、図５および図６または図１７に示したマンマシンチャートと要素作業タイムチャートとを両方、端末９の表示装置９１に表示させるものとした。しかし、この場合、設備１の管理者、分析者等には、初めから詳細な情報が与えられる。このため、設備１の管理者、分析者等は、詳細な情報の中から確認の必要な情報を探すことになる。したがって、設備１の管理者、分析者等は、確認の作業に手間取る場合があり得る。そこで、本実施の形態３では、初めにマンマシンチャートだけを表示装置９１に表示させ、設備１の管理者、分析者等が必要に応じて要素作業タイムチャートを見られるようにする。 (Embodiment 3)
In the first and second embodiments described above, the production improvement support system 100 shown in FIG. 1 uses the man-machine chart and element work time chart shown in FIG. 5 and FIG. 6 or FIG. It is supposed to be displayed on 91. However, in this case, the manager, the analyst, etc. of the equipment 1 are given detailed information from the beginning. For this reason, the manager, the analyst, etc. of the equipment 1 will search for the information that needs to be confirmed from the detailed information. Therefore, the manager of the facility 1, the analyst, etc. may take time to perform the confirmation work. Therefore, in the third embodiment, only the man-machine chart is first displayed on the display device 91 so that the manager of the equipment 1, the analyst, etc. can see the element work time chart as needed.
　生産改善支援システム１００は、予め設定された作業時間を超過した作業者状態の区間の色を他の作業者状態の区間とは異なる色としたマンマシンチャートだけを表示装置９１に表示させる。設備１の管理者、分析者等が、タイムチャートのうち、色の異なる作業者状態の区間を表示画面上で選択した場合、生産改善支援システム１００は、その区間に対応する要素作業タイムチャートを表示させる。なお、マンマシンチャートにおいて、予め設定された作業時間を超過した作業者状態が複数ある場合、作業者状態の区間の色は、全て同じ色、または、それぞれ異なる色に設定してもよい。 The production improvement support system 100 causes the display device 91 to display only the man-machine chart in which the color of the section in the worker state that exceeds the preset work time is different from the color in the sections in the other worker states. When the manager, the analyst, or the like of the equipment 1 selects a section in the worker state with different colors on the display screen from the time chart, the production improvement support system 100 displays the element work time chart corresponding to the section. Display it. In the man-machine chart, when there are a plurality of worker states that have exceeded the preset work time, the colors of the sections in the worker state may all be set to the same color or different colors.
　例えば、図１８に示すマンマシンチャートの項目「治具交換」が、予め設定された作業時間を超過した作業者状態であるものとする。この場合、生産改善支援システム１００は、治具交換を示す区間Ｔ１０１の色に他の区間と異なる色を設定する。続いて、区間Ｔ１０１を、設備１の管理者、分析者等が表示画面上で選択した場合、生産改善支援システム１００は、区間Ｔ１０１に対応する期間の要素作業タイムチャートを生成する。生産改善支援システム１００は、生成した要素作業タイムチャートを、区間Ｔ１０１と対応付けて表示装置９１に表示させる。 For example, it is assumed that the item “jig change” in the man-machine chart shown in FIG. 18 is a worker state that exceeds a preset work time. In this case, the production improvement support system 100 sets the color of the section T101 indicating the jig replacement to a color different from the other sections. Then, when the manager of the equipment 1, the analyst, or the like selects the section T101 on the display screen, the production improvement support system 100 generates an element work time chart for the period corresponding to the section T101. The production improvement support system 100 causes the display device 91 to display the generated element work time chart in association with the section T101.
　なお、生産改善支援システム１００は、要素作業タイムチャートを生成する際、その要素作業タイムチャートの内、最も長い要素作業の区間の色に、他の要素作業の区間の色と異なる色を設定してもよい。例えば、図１８に示す要素作業タイムチャートにおいて、作業者３は、要素作業の治具取り付けに、最も時間がかかったものとする。この場合、生産改善支援システム１００は、治具取り付けを示す区間Ｔ１０２の色に他の区間と異なる色を設定する。 The production improvement support system 100 sets the color of the longest element work section in the element work time chart to a color different from the colors of other element work sections when the element work time chart is generated. May be. For example, in the element work time chart shown in FIG. 18, it is assumed that the worker 3 took the longest time to attach the jig for the element work. In this case, the production improvement support system 100 sets the color of the section T102 indicating jig attachment to a color different from that of the other sections.
　本実施の形態３に係るマンマシンチャートと要素作業タイムチャートとの表示について、図１９に示した生産改善支援システムの動作処理のフローチャートを参照し説明する。ステップＳ７０１からステップＳ７０７については、図１１に示した生産改善支援システム１００の動作処理のフローチャートの処理と同様である。また、ステップＳ７０８については、実施の形態２で説明したマンマシンチャート表示処理と同様である。 The display of the man-machine chart and the element work time chart according to the third embodiment will be described with reference to the flowchart of the operation processing of the production improvement support system shown in FIG. Steps S701 to S707 are the same as the processing of the flowchart of the operation processing of the production improvement support system 100 shown in FIG. Further, step S708 is the same as the man-machine chart display process described in the second embodiment.
　図１に示した生産改善支援システム１００の設備制御部４は、設備１の管理者、分析者等により、タイムチャートのうち、色の異なる作業者状態の区間が表示画面上で選択されたか否かを判定する（ステップＳ７０９）。設備１の管理者、分析者等により選択された場合（ステップＳ７０９；ＹＥＳ）、設備制御部４は、端末９に要素作業タイムチャート表示処理を実行させる（ステップＳ７１０）。要素作業タイムチャート表示処理については、実施の形態２で説明した処理と同様である。また、設備１の管理者、分析者等により選択されなかった場合（ステップＳ７０９；ＮＯ）、設備制御部４はステップＳ７０１に戻る。設備制御部４はステップＳ７０１からステップＳ７１０までの処理を繰り返す。 The equipment control unit 4 of the production improvement support system 100 shown in FIG. 1 determines whether the manager of the equipment 1, the analyst, or the like has selected, on the display screen, a section in a worker state with different colors in the time chart. It is determined (step S709). When selected by the manager of the equipment 1, the analyst, or the like (step S709; YES), the equipment control unit 4 causes the terminal 9 to execute the element work time chart display process (step S710). The element work time chart display process is the same as the process described in the second embodiment. Moreover, when it is not selected by the administrator, the analyst, or the like of the equipment 1 (step S709; NO), the equipment control unit 4 returns to step S701. The equipment control unit 4 repeats the processing from step S701 to step S710.
　以上のように、実施の形態３では、生産改善支援システム１００は、初めにマンマシンチャートのみ表示装置９１に表示させる。そして、生産改善支援システム１００は、他の区間と色を異ならせた作業者状態の区間を設備１の管理者、分析者等が表示画面上で選択した場合、その作業者状態を示す区間に対応する期間の要素作業タイムチャートを生成し、表示装置９１に表示させる。これにより、設備１の管理者、分析者等には初めから詳細な情報が与えられないため、確認の作業に手間取る可能性を低減することができる。また、設備１の管理者、分析者等が、問題の生じていない要素作業に対して、改善を検討してしまう間違いを抑制することができる。 As described above, in the third embodiment, the production improvement support system 100 initially displays only the man-machine chart on the display device 91. Then, when the administrator of the equipment 1, the analyst, or the like selects a section in the worker state whose color is different from that of the other section on the display screen, the production improvement support system 100 selects the section indicating the worker state. The element work time chart for the corresponding period is generated and displayed on the display device 91. As a result, detailed information cannot be given to the manager, the analyst, and the like of the equipment 1 from the beginning, so that it is possible to reduce the possibility of troublesome confirmation work. Further, it is possible to suppress an error in which the manager, the analyst, or the like of the equipment 1 considers the improvement for the elemental work in which no problem has occurred.
　また、本開示の実施の形態１から３では、生産改善支援システム１００を設備制御部４、サーバ５、処理装置７、端末９を協同させることにより、実現できるものとした。しかしながら、専用のシステムによらず、通常のコンピュータシステムを用いて実現可能である。例えば、上述の設備制御部４、サーバ５、処理装置７、端末９における各機能を実現するためのプログラムを、コンピュータが読み取り可能なＣＤ－ＲＯＭ（Ｃｏｍｐａｃｔ　Ｄｉｓｃ　Ｒｅａｄ　Ｏｎｌｙ　Ｍｅｍｏｒｙ）、ＤＶＤ－ＲＯＭ（Ｄｉｇｉｔａｌ　Ｖｅｒｓａｔｉｌｅ　Ｄｉｓｃ　Ｒｅａｄ　Ｏｎｌｙ　Ｍｅｍｏｒｙ）などの記録媒体に格納して配布し、このプログラムをコンピュータにインストールすることにより、上述の各機能を実現することができるコンピュータを構成してもよい。そして、各機能をＯＳ（Ｏｐｅｒａｔｉｎｇ　Ｓｙｓｔｅｍ）とアプリケーションとの分担、またはＯＳとアプリケーションとの協同により実現する場合には、アプリケーションのみを記録媒体に格納してもよい。 In addition, in the first to third embodiments of the present disclosure, the production improvement support system 100 can be realized by cooperating the facility control unit 4, the server 5, the processing device 7, and the terminal 9. However, it can be realized by using an ordinary computer system instead of a dedicated system. For example, a computer-readable CD-ROM (Compact Disc Read Only Memory) or DVD-ROM (Digital) stores programs for realizing the functions of the equipment control unit 4, the server 5, the processing device 7, and the terminal 9 described above. A computer capable of realizing the above-described functions may be configured by storing and distributing the program in a recording medium such as Versatile Disc Read Only Memory) and installing the program in the computer. Then, when each function is realized by the sharing of the OS (Operating System) and the application or the cooperation of the OS and the application, only the application may be stored in the recording medium.
