The CPU 201 controls various motors (not shown) in the drive unit 202 using the NC data and the control program. For this purpose, the CPU 201 sends a drive control signal, a primary stop signal, and the like to the drive unit 202.
また、このCPU201は、操作盤203との間で、制御信号の送受信を行う。例えば、操作者が操作盤203の起動スイッチ(図示せず)をオンすると、起動信号がCPU201に送られて、NC工作機120が稼働を開始する。また、例えば、操作者が操作盤203のオーバーライドダイヤル(図示せず)を操作した場合には、駆動部202での切削速度を変更させるための制御信号が、CPU201へ送られる。一方、例えば、CPU201でアラーム信号が生成されて操作盤203に送られ、この操作盤203でアラーム告知(アラーム音の出力やアラーム光の点滅等)が行われる場合もある。なお、各制御信号は、1ビットの信号であっても良いし、複数ビットの信号であっても良い。
The CPU 201 transmits and receives control signals to and from the operation panel 203. For example, when an operator turns on a start switch (not shown) of the operation panel 203, a start signal is sent to the CPU 201, and the NC machine tool 120 starts operation. Further, for example, when the operator operates an override dial (not shown) of the operation panel 203, a control signal for changing the cutting speed in the drive unit 202 is sent to the CPU 201. On the other hand, for example, an alarm signal may be generated by the CPU 201 and sent to the operation panel 203, and an alarm notification (output of an alarm sound, blinking of alarm light, etc.) may be performed on the operation panel 203. Each control signal may be a 1-bit signal or a multi-bit signal.
この実施の形態1では、CPU201と駆動部202や操作盤203との間で送受信された制御信号の一部を、稼働状況監視装置130にも送る。図2の例では、信号ケーブル205a,205b,205c,205dの制御信号が、信号ケーブル206a,206b,206c,206dを介して、稼働状況監視装置130に送られる。なお、図2の例では、4種類の制御信号C1-C4を稼働状況監視装置130へ送ることとしたが、1~3種類でも良いし、5種類以上でも良いことは、もちろんである。
In the first embodiment, a part of a control signal transmitted / received between the CPU 201 and the drive unit 202 or the operation panel 203 is also sent to the operation status monitoring device 130. In the example of FIG. 2, control signals for the signal cables 205a, 205b, 205c, and 205d are sent to the operation status monitoring apparatus 130 via the signal cables 206a, 206b, 206c, and 206d. In the example of FIG. 2, four types of control signals C1 to C4 are sent to the operation status monitoring device 130. However, one to three types or five or more types may be used.
信号ケーブル205a-205dと信号ケーブル206a-206dとの接続には、通常の半田付けやコネクタ等を使用しても良いが、この実施の形態1では、クランプ型交流電流センサ207a,207b,207c,207dを使用する。クランプ型交流電流センサとは、交流電流センサのクランプ部で信号ケーブル(ここでは信号ケーブル205a-205d)を挟み込んで、これら交流電流センサが検出した信号変化(パルス信号のターンオン及びターンオフ)を出力するセンサである。交流電流センサ207a-207d用いることにより、信号ケーブル205a-205d切断すること無しに(すなわち、NC工作機120を改造すること無しに)、これら信号ケーブル205a-205dの制御信号を信号ケーブル206a-206dに出力させることができる。クランプ型交流電流センサとしては、例えば特願2016-040321に記載されたものが知られている。
For connection between the signal cables 205a-205d and the signal cables 206a-206d, normal soldering or connectors may be used. In the first embodiment, the clamp-type AC current sensors 207a, 207b, 207c, Use 207d. The clamp-type AC current sensor sandwiches a signal cable (here, signal cables 205a to 205d) at a clamp portion of the AC current sensor, and outputs a signal change (turn-on and turn-off of a pulse signal) detected by these AC current sensors. It is a sensor. By using the AC current sensors 207a-207d, the control signals of these signal cables 205a-205d can be transmitted to the signal cables 206a-206d without disconnecting the signal cables 205a-205d (ie, without modifying the NC machine tool 120). Can be output. As a clamp type alternating current sensor, for example, one described in Japanese Patent Application No. 2016-040321 is known.
更に、CPU201は、所望の情報を、印刷情報Pとして、印刷インタフェース204に送信する機能を有する。公知のように、NC工作機としては、そのNC工作機内に設けた各種センサ(図2では示さず)の検出値等を、印刷情報として出力する機能(すなわち、制御プログラムに各種センサの検出値等を印刷情報化して出力する命令を含ませておいて、CPU201にその命令を実行させる機能)を備えたものが知られている。このようなNC工作機では、その印刷機能を用いて、予め定めた文字情報(コメント)をプリンタに印刷させるための印刷情報を、出力させることが可能である。すなわち、所定の文字情報を印刷情報として出力する命令を制御プログラム内に記述しておいて、CPU201に実行させることができる。この実施の形態1では、このような印刷機能を利用して、加工物の種別や製造工程の進捗段階を示す文字情報を、CPU201に出力させる。例えば、加工の開始時には、加工対象物の名称を印刷情報として出力させ、その後、「加工開始」、「切削が○○%終了」、「加工の終了まで○○分」、「工具交換作業開始」、「緊急停止処理中」等の文字を出力させることができる。
Further, the CPU 201 has a function of transmitting desired information as print information P to the print interface 204. As is well known, an NC machine tool has a function of outputting detection values of various sensors (not shown in FIG. 2) provided in the NC machine tool as print information (that is, detection values of various sensors in a control program). And the like which include a command for converting the information into print information and outputting it, and having a function of causing the CPU 201 to execute the command. In such an NC machine tool, it is possible to output print information for causing a printer to print predetermined character information (comments) using the print function. That is, a command for outputting predetermined character information as print information can be described in the control program and executed by the CPU 201. In the first embodiment, using such a printing function, the CPU 201 outputs character information indicating the type of workpiece and the progress stage of the manufacturing process. For example, at the start of machining, the name of the object to be machined is output as print information, and then "machining start", "cutting is completed XX%", "until machining is completed", and "tool change work starts" "," Emergency stop process in progress ", etc. can be output.
印刷インタフェース204は、CPU201から入力した印刷情報を、稼働状況監視装置130へ出力する。後述するように、この実施の形態1では、かかる印刷情報を、稼働状況監視装置130に稼働状態を判定させるための情報として使用する(後述)。
The print interface 204 outputs the print information input from the CPU 201 to the operation status monitoring apparatus 130. As will be described later, in the first embodiment, such print information is used as information for causing the operating status monitoring apparatus 130 to determine the operating status (described later).
なお、文字情報を稼働状況監視装置130へ提供する方法は、CPU201の印刷機能を用いた方法に限定されない。例えば、NC工作機120の稼働状況等に応じて、操作者がバーコードリーダを操作して複数種類のバーコードの何れかを選択的に読み取ることとし、読み取ったバーコード情報(光学情報)を文字情報に変換して、稼働状況監視装置130へ送る方法も可能である。この方法によれば、バーコードを読み取るという簡単な操作のみで文字情報を取り込むことができる。
Note that the method of providing character information to the operation status monitoring apparatus 130 is not limited to the method using the printing function of the CPU 201. For example, according to the operating status of the NC machine tool 120, the operator operates the barcode reader to selectively read one of a plurality of types of barcodes, and reads the read barcode information (optical information). A method of converting to character information and sending it to the operation status monitoring apparatus 130 is also possible. According to this method, it is possible to capture character information with only a simple operation of reading a barcode.
図3は、稼働状況監視装置130の要部構成を概略的に示すブロック図である。
FIG. 3 is a block diagram schematically showing a main configuration of the operation status monitoring device 130. As shown in FIG.
図3に示したように、この稼働状況監視装置130は、データ取得部310と、データ保存・判定部320とを備える。
As shown in FIG. 3, the operating status monitoring apparatus 130 includes a data acquisition unit 310 and a data storage / determination unit 320.
データ取得部310は、文字情報取得部311と、制御信号取得部312とを備える。

文字情報取得部311は、NC工作機120の印刷インタフェース204から印刷情報Pを取り込んで、一時的に保存する。そして、その印刷情報Pから文字情報を取り出して、データ保存・判定部320へ出力する。
The character information acquisition unit 311 takes the print information P from the print interface 204 of the NC machine tool 120 and temporarily stores it. Then, character information is extracted from the print information P and output to the data storage / determination unit 320.
制御信号取得部312は、NC工作機120の信号ケーブル206a-206dを介して、制御信号C1-C4を、パラレルに逐次取り込む。
The control signal acquisition unit 312 sequentially receives the control signals C1 to C4 in parallel via the signal cables 206a to 206d of the NC machine tool 120.
最初に制御信号C1-C4を取り込んだとき、この制御信号取得部312は、これらの制御信号C1-C4を内部メモリに一時保存すると共に、データ保存・判定部320へ出力する。
When the control signals C 1 -C 4 are first captured, the control signal acquisition unit 312 temporarily stores these control signals C 1 -C 4 in the internal memory and outputs them to the data storage / determination unit 320.
その後、制御信号取得部312は、制御信号C1-C4を新しく取り込むたびに、その制御信号C1-C4の値を一時保存された信号値と比較する。そして、両者が一致しない場合に、制御信号取得部312は、内部メモリの保存値を新しく取り込んだ制御信号C1-C4の信号値に書き換えると共に、データ保存・判定部320へ出力する。このような方法によれば、制御信号値が変化した場合にのみ、その制御信号値をデータ保存・判定部320へ送ることができ、その結果、データベース322(後述)の容量を節約することができる。但し、制御信号値が変化したか否かに拘わらず、所定の時間間隔でデータ保存・判定部320へ送ることとしても良い。
Thereafter, every time the control signal C1-C4 is newly fetched, the control signal acquisition unit 312 compares the value of the control signal C1-C4 with the temporarily stored signal value. If the two do not match, the control signal acquisition unit 312 rewrites the stored value in the internal memory to the newly acquired signal value of the control signal C1-C4 and outputs it to the data storage / determination unit 320. According to such a method, only when the control signal value changes, the control signal value can be sent to the data storage / determination unit 320. As a result, the capacity of the database 322 (described later) can be saved. it can. However, the data may be sent to the data storage / determination unit 320 at a predetermined time interval regardless of whether the control signal value has changed.
データ保存・判定部320は、制御部321と、データベース322と、判定テーブル記憶部323と、表示部324とを備える。
The data storage / determination unit 320 includes a control unit 321, a database 322, a determination table storage unit 323, and a display unit 324.

The control unit 321 receives the character information and the signal values of the control signals C1-C4 from the character information acquisition unit 311 and the control signal acquisition unit 312 of the data acquisition unit 310. Then, the time information is added to the received character information and control signal value, and stored in the database 322.
また、制御部321は、入力された文字情報や制御信号C1-C4の信号値と、判定テーブルとを用いて、NC工作機120の稼働状況を判定すると共に、その判定結果を表示部324へ送る(詳細は後述)。
In addition, the control unit 321 determines the operating status of the NC machine tool 120 using the input character information, the signal values of the control signals C1 to C4, and the determination table, and the determination result to the display unit 324. Send (details will be described later).

データベース322としては、例えばハードディスク等が使用される。このデータベース322は、例えば、インターネット等の通信回線を用いて、遠隔の端末機から文字情報や制御信号値を読み出せるようにしてもよい。
As the database 322, for example, a hard disk or the like is used. The database 322 may be configured such that character information and control signal values can be read from a remote terminal using a communication line such as the Internet.
表示部324は、制御部321から受け取った判定結果を表示する。表示部324としては、例えばディスプレイ装置等を利用できる。

例えば、制御信号C1-C4のうち一次停止やアラームを示す制御信号がオフしており(すなわち一次停止中でもアラーム発動状態でも無いことを示しており)、文字情報も正常動作を示している(例えば「加工開始」や「切削が○○%終了」等)場合、制御部321は、「正常稼働中」との判定結果を得る。
For example, the control signal indicating the primary stop or alarm in the control signals C1 to C4 is OFF (ie, indicating that neither the primary stop nor the alarm is activated), and the character information also indicates normal operation (for example, In the case of “machining start” or “cutting is finished XX%”), the control unit 321 obtains a determination result of “normally operating”.
また、例えば、制御信号C1-C4のうちアラームを示す制御信号がオンしており(アラーム発動状態であることを示しており)、文字情報が「緊急停止処理中」である場合、制御部321は、「異常発生中」との判定結果を得る。
Further, for example, when the control signal indicating the alarm among the control signals C1 to C4 is ON (indicating that the alarm is activated) and the character information is “processing emergency stop”, the control unit 321 Obtains a determination result that “abnormality is occurring”.
制御部321は、この判定結果を、表示部324に表示させる。このとき、この判定結果と同時に、制御信号C1-C4の信号値や文字情報を、表示部324に表示させることにしてもよい。この表示部324としては、例えばディスプレイ装置等を使用できる。
