本発明は、各種製造ラインにおいて、作業者並びに生産管理者が製造ラインの稼動状況等を瞬時に把握する事を可能とする為の表示を行う表示装置の情報の通信方法に関する。The present invention relates to a method for communicating information on a display device that performs display to enable an operator and a production manager to instantaneously grasp the operating status of a production line in various production lines.
各種製造ラインにおいて、各工作機械や製造ライン並びに工場全体の稼動状況等を作業者又は生産管理者が瞬時に把握することを可能とする為に、工作機械の上部もしくは工場の天井付近へ表示装置を設置し、該表示装置に各工作機械からの情報を外部集計装置により集計した値を表示させている。前記表示内容には、工作機械の個々の稼動状況、稼働率、生産個数、各ライン及び工場全体の稼動率や生産個数等の項目が上げられ、各工作機械からの情報を外部集計装置にて集計後グラフ等の見易い表示形式へ編集を行い、表示装置に表示を行っている。In various production lines, in order to make it possible for an operator or production manager to instantly grasp the operation status of each machine tool, production line, and the entire factory, a display device is provided above the machine tool or near the ceiling of the factory. The information obtained from each machine tool is displayed on the display device by using the external totaling device. The display contents include items such as the individual operating status, operating rate, number of production of each machine tool, operating rate and number of production of each line and the whole factory, and information from each machine tool is collected by an external totaling device. Edited into an easy-to-read display format such as a graph after aggregation, and displayed on the display device.
前記の様に表示装置を工作機械の上部又は工場の天井付近に設置を行う為には、工作機械の上部又は工場の天井付近に設置した表示装置へ電源線と信号線の二本の配線が必要となり、設置場所によっては数十メートルの距離の配回しを行わなければならず、信号線等の設備費や配線の配回し作業に非常に多くの工数が必要となり問題となっていた。In order to install the display device on the upper part of the machine tool or near the ceiling of the factory as described above, the power supply line and the signal line are connected to the display device installed on the upper part of the machine tool or near the ceiling of the factory. Depending on the installation location, it has to be distributed at a distance of several tens of meters, which is a problem because it requires a very large number of man-hours for equipment costs such as signal lines and wiring.
表示装置への配線並びに配線工数を削減する方法として、無線ＬＡＮを使用することで信号線と信号線の配線工数の削減を行う方法が有るが、前記方式の場合、工場内における無線チャンネル数に限りが有る為、大規模な製造ラインに対応する事が困難なうえに、工場内において稼動中の工作機械や産業用ロボット等より発生する電気的なノイズの影響により誤表示してしまう等の問題が有った。
本発明は各種製造ラインにおいて、製造ラインの稼動状況等の表示を行う表示装置を設置する際にデータ通信用の信号線の配線を行う必要を無くすことで、設備費並びに設置工数の低減を可能にすると共に、加工機や産業用ロボットから発生する電気的ノイズの影響を受ける事のない表示装置とする。更に、製造ラインの変更を行った場合にも容易に対応可能とすることで設備費並びに設置工数の低減が可能な表示装置を提供することを目的とする。The present invention eliminates the need to wire signal lines for data communication when installing a display device that displays the operational status of the production line in various production lines, thereby reducing equipment costs and installation man-hours. In addition, the display device is not affected by electrical noise generated from a processing machine or industrial robot. Furthermore, it aims at providing the display apparatus which can reduce an installation cost and an installation man-hour by enabling it to respond easily also when a production line is changed.
本発明は、前記した問題を解決する手段として、表示装置側に電力線通信用のスレイブユニットを、各工作機械からの情報の集計を行う集計装置側へ電力線通信用のマスターユニットを配設し、集計装置と表示装置間の情報の通信方法を電力線に信号を重畳させた通信方法とする。As a means for solving the above-mentioned problems, the present invention provides a slave unit for power line communication on the display device side, and a master unit for power line communication on the aggregation device side for totaling information from each machine tool, The information communication method between the counting device and the display device is a communication method in which a signal is superimposed on the power line.
以上説明したように、表示装置への表示情報の通信方式に、電力線に信号を重畳させる電力線通信方式を採用したことで、従来表示装置を設置する場合電源線と信号線の二本の配線が必要であったが、電力線に信号を重畳することで信号線を無くすことが可能となり設備費の削減と設置工数の大幅な削減を行うことが出来た。As described above, by adopting the power line communication method that superimposes the signal on the power line as the communication method of the display information to the display device, when installing the conventional display device, the two wirings of the power line and the signal line are Although it was necessary, it was possible to eliminate the signal line by superimposing the signal on the power line, and it was possible to reduce equipment costs and installation man-hours.
また、電力線は、工場内に設置される１００Ｖのコンセントを使用することが出来るため、専用に電力線を引く必要が無く、設備の追加やライン構成の変更等にも容易に対応することが可能となった。In addition, because the power line can use a 100V outlet installed in the factory, there is no need to draw a dedicated power line, and it is possible to easily cope with the addition of equipment and changes in the line configuration. became.
以下、本発明の実施の形態を図面に基づいて説明する。

FIG. 1 shows a schematic configuration diagram of a production management system of the present invention.
図１において複数の工作機械や製造ラインが集計装置に接続され、該集計装置により集計された値がグラフ等の見易い形式に編集され表示装置へ表示される。In FIG. 1, a plurality of machine tools and production lines are connected to a totaling device, and values totaled by the totaling device are edited into an easy-to-read format such as a graph and displayed on a display device.
各種製造ライン内に設置される複数の工作機械の個々の動作状態の集計を行い、製造ラインの工作機械の稼動状況や生産個数等の情報を表示装置において表示する為に、工作機械のＩ／Ｏ出力より工作機械の動作状況を示す信号を出力し、該信号が信号線を介し集計装置へ入力される。The I / O of the machine tool is used to aggregate the individual operating states of a plurality of machine tools installed in various production lines and display information such as the operation status and the number of production of the machine tools on the production line on the display device. A signal indicating the operation status of the machine tool is output from the O output, and the signal is input to the counting device via the signal line.
入力された工作機械の動作状態を示す信号を基に集計装置内において集計を行い、製造ラインの稼動状況、生産個数、個々の工作機械の動作状態等の情報へ編集を行う。Based on the input signal indicating the operating state of the machine tool, the totaling is performed in the totaling device, and information such as the operating status of the production line, the number of production, and the operating status of each machine tool is edited.
編集された情報は集計装置から表示装置へ通信され各種情報の表示を行う。The edited information is communicated from the aggregation device to the display device and various information is displayed.
集計装置と表示装置間の通信には、集計装置側に電力線通信用のマスターユニットが接続、表示装置側に電力線通信用のスレイブユニットが接続され両ユニットがコンセントに接続されることにより電力線に重畳した信号の通信が可能となる。For communication between the counting device and the display device, a master unit for power line communication is connected to the counting device side, a slave unit for power line communication is connected to the display device side, and both units are connected to an outlet so that they are superimposed on the power line. The signal can be communicated.
上記構成は、各種製造ラインにおける生産管理システムの表示装置への通信方法に関するものであるが、本発明の通信方法は各種装置へのデータ通信等においても有効である。The above configuration relates to a communication method to the display device of the production management system in various production lines, but the communication method of the present invention is also effective in data communication to various devices.
