技 術 分 野 Technical field
本発明は、 数値制御装置と工作機械用プ口ダラマブルコ ン ト ロ ーラ間のプログラムフォーマッ ト変換方式に関するものであ る。 背 景 術  TECHNICAL FIELD The present invention relates to a program format conversion method between a numerical controller and a programmable dramable controller for a machine tool. Background art
従来、 数値制御 （ N C ) 装置に与える N C加ェプ口 グラムは その N C固有のプログラムフォー マッ トのみを使って記述しな ければ-ならなかった。 この為、 工作機械メ ーカが数値制御装置 を購入し、 自社で製造した工作機械と結合させて数値制御工作 機械を構成した場合であって、 独自の N C加ェプログラムをュ —ザに提供する場合でも、 その N C加工プログ ムは数値制御 装置で規定された種類のプログラムフォーマッ トを採用しなけ ればならず、 同種類の数値制御装置を採用する他社の数値制御 1：作機械に容易に転用される危惧があった。  Conventionally, an NC program given to a numerical control (NC) device had to be described using only the NC-specific program format. For this reason, when a machine tool manufacturer purchases a numerical control device and combines it with a machine tool manufactured in-house to construct a numerically controlled machine tool, a unique NC programming program is provided to the user. In such cases, the NC machining program must use the program format of the type specified by the numerical control device, and other companies' numerical control using the same type of numerical control device is easy for machine tools. There was a fear of being diverted to.
そこで、 N C加工プログラムを、 数値制御装置固有のプログ ラムフォーマツ ト以外に工作機械メ 一力独自のフォ —マツ トで も記述できるよう にした数値制御装置が最近において実現され た。 このよう な数値制御装置では、 N C加工プログラム中に所 定のプログラムフォーマツ ト以外のフォーマツ トで記述された データがある場合、 これを工作機械用プログラマブルコ ン ト ロ ーラに送出し、 プログラマブルコ ン ト ローラ内で数値制御装置 が実行し得るフォーマツ トに変換し、 再び数値制御装置に返送 して数値制御やプロダラムの登録を行なわせるものであり、 ェ 作機械用プログラマブルコ ン ト ロ—ラ内における上記変換の内 容を工作機械メ —力で独自に作成しておく ことにより、 工作機 械メ 一力独自のプログラムフォーマッ トを使用することが可能 となるものである。 なお、 プログラムフォーマッ トの変換を数 値制御装置で行なわせると、 工作機械メ 一力に数値制御装置內 部の変更を許容する必要があり、 信頼性確保上問題があると共 に数値制御装置の汎用性が阻害されるので、 上述のように工作 機械用プログラマブルコ ン ト ローラ内で変換を行なわせるよう にしたものである。 Therefore, a numerical control device has recently been realized in which NC machining programs can be described not only in the format specific to the numerical control device but also in a format unique to machine tool manufacturers. In such a numerical controller, the NC machining program is described in a format other than the specified program format. If there is data, it is sent to the programmable controller for machine tools, converted into a format that can be executed by the numerical controller in the programmable controller, and returned to the numerical controller again to return the numerical value. Control and program registration are performed, and the contents of the above-mentioned conversion in the programmable controller for machine tools are created independently by machine tool force. This makes it possible to use a unique program format. In addition, if the conversion of the program format is performed by a numerical controller, it is necessary to allow a change in the numerical controller part in the machine tool, and there is a problem in securing reliability, and the numerical controller is also required. Since the general versatility of this is hindered, the conversion is performed in the programmable controller for the machine tool as described above.
ところで、 従来の上述のようなプログラムフォーマツ 卜の変 換は、 変換の必要なデータが文字数にして 1 2 8文字分たまる と、 これを 1 ブロック としてェ作機械用プログラマブルコ ン ト ローラに送出し、 プログラマブルコ ン ト ローラでフォーマツ ト 変換されて得られたデータが文字数にして 1 2 8文字分たまる と、 これを 1 ブロック と して数値制御装置に返送する如く 、 ブ ロック転送形式を採用していたので、 数値制御装置側で変換後 のデータを読む時に待ち時間が生じる等の不都合があった。 発 明 の 開 示  By the way, in the conventional program format conversion as described above, when the data that needs to be converted accumulates 128 characters in terms of the number of characters, this is sent as a block to a programmable controller for a machine tool. The block transfer format is adopted so that when the data obtained by format conversion by the programmable controller accumulates 128 characters in terms of the number of characters, it is returned to the numerical controller as one block. Therefore, there was an inconvenience such as waiting time when reading the converted data on the numerical controller. Disclosure of the invention

ROM 3 is a memory for storing the system program of the NC processor 1, RAM 4 is a memory having an area for temporarily storing calculation results, etc., and an external memory 5 is an NC processing program. The memory 5 is composed of a magnetic bubble memory, a CM0S memory with a backup power supply, and the like. The keyboard 6 is for inputting various data and commands.

The position control circuit 8 and the speed control circuit 9 are connected to the speed detector 1] and the position detector 12 This is a circuit for driving the motor 10 to the specified position at the specified speed based on the speed and position feedback signals. In the figure, only one putter is shown, and it is actually provided for each channel. The input / output control circuit 13 is a circuit that generates a command for executing jog feed and step feed in accordance with a signal from the jog step feed switch 14.

The processor 20 and the NC processor i can exchange data with each other via the common RAM 30, and as is well known, the M, S, τ code, etc. are transmitted from the NC processor 1 via the common RAM 30 to the NC processor i. Is sent to the processor 20, the processor 20 decodes the signal and, at a predetermined timing, for example, signals necessary for tool change, etc. from the input / output control circuit 23.
N C用プロセッサ 1 とプログラマブルコ ン トローラ用のプロ セッサ 20とはまた、 出力バッファ 31と入力バッファ 32で相互に 接続されている。 出力バッファ 31は N C用プロセッサ 1からフ ォーマツ ト変換すべきデータを 1文字ずつプログラマブルコ ン ト ローラ側に送出するためのバッファであり、 入力バッファ 32 はプロセッサ 20でフォーマツ ト変換されたデータを 1文字ずつ 数値制御装置側に送出するためのデータである。  The NC processor 1 and the programmable controller processor 20 are also interconnected by an output buffer 31 and an input buffer 32. The output buffer 31 is a buffer for sending the data to be format-converted from the NC processor 1 to the programmable controller side one character at a time, and the input buffer 32 stores the data that has been format-converted by the processor 20 as one. This data is sent character by character to the numerical controller.
次に、 本発明によるフォーマツ ト変換の動作について説明す る。 外部メ モリ 5に記憶された N C加エブ πグラムは複数のブ口 ック （ 1単位として抜える連続したヮー ドの集りでェン ドォブ ブ αックを示す文字で互いに区別される） から成るが、 数値制 御装置固有のフォーマツ 卜で記戴されたブロック と、 工作機械 メ ーカ独自のフォーマツ トで記載されたブロック とが混在して いる。 Next, the operation of the format conversion according to the present invention will be described. The NC memory π-gram stored in the external memory 5 is obtained from a plurality of blocks (a group of consecutive cards that can be extracted as one unit and is distinguished from each other by a character indicating an end block α). However, blocks written in a format unique to the numerical control device and blocks written in a format unique to the machine tool manufacturer are mixed.
N C用プロセッサ 1 は、 数値制御の実行指令或はプロセッサ の登録指令が入力されると、 例えば第 2図に示すように外部メ モリ 5に記憶された N C加工プログラムをその先頭から順々に 1 ブロックずつ読取る （ S 1 ) 。 そして、 当該ブロックがフォ 一マッ ト変換する必要があるか否かを I！别する （ S 2 ) 。 フォ 一マツ ト変換すべきプロックにはその旨を示す情報が含まれて いるので、 その情報の有無によって判別を行なう。 N C用プロ セッサ 1 はフォーマッ ト変換の必要がない場合、 そのブロック を解読して実行準備を行ない （ S 7 ) 、 数値制御指令が発せら れているときはパルス分配を行なつて位置制御回路 8 を制御し また工具交換指令等の場合は共通 R A Μ 30を介してプロセッサ 20にデータを送出し、 更に , プログラムの登録指令が発せられ ている場合はそのブロックの内容を外部メ モ リ 5 の別の領域に 記憶する （ S 8 ) 。 一方、 フォーマッ ト変換が必要なブロック の場合は、 そのブロックを 1 文字ずつ出力バッファ 3 1に送出す る （ S 3 ) 。  When a numerical control execution command or a processor registration command is input, the NC processor 1 sequentially reads the NC machining programs stored in the external memory 5 one by one from the top as shown in FIG. Read block by block (S1). Then, it is determined whether or not the block needs to be transformed. Yes (S2). Since the block to be format-converted contains information indicating that fact, the determination is made based on the presence or absence of the information. If format conversion is not necessary, the NC processor 1 decodes the block and prepares for execution (S7). If a numerical control command is issued, the NC processor 1 performs pulse distribution to perform position control. In the case of a tool change command, etc., data is sent to the processor 20 via the common RA 30. In addition, if a program registration command is issued, the contents of the block are stored in external memory. The data is stored in another area (S8). On the other hand, if the block requires format conversion, the block is sent to the output buffer 31 one character at a time (S3).
プロセッサ 20は、 出力バッファ 3〗にデータがセッ ト されたこ とにより割込みがかけられ、 例えば第 3図に示すような処理を 実行する。 即ち、 割込みがかかると出力バッファ 3 1の先頭文字 を読取り （ S 1 0 ) 、 一旦 R A M 22に耘送する。 そして、 この読 取った文'字がブロックの終了コ ー ド （エン ドォブブロック） や 変換の区切り記号等でな く今まで読取ったデータだけでは変換 が可能でない場合は割込み処理を終了してメ ィ ンルーチンへ復 帰する （ S 1 1 ) 。 出力バッファ 31に文字が連続して入力された 場合、 メ イ ンルーチンへ復帰すると再び割込みがかかり、 プロ セッサ 20は再び第 3図の処理を実行する。 そして、 ブロックの 終了コー ド （ェ ン ドォブブロック） や変換の区切り記号等を識 別し、 変換が可能と判別すると、 予め R 0 M 21に記憶されたフ ォ—マツ ト変換マップを参照して当該データのフォーマツ トを 変換し （ S 1 2 ) 、 変換して得たデ一-タを 1文字ずつ入力バッフ ァ 32に送出して処理を終了する （ S 1 3 ) 。 The processor 20 is interrupted by the data set in the output buffer 3 #, and executes, for example, the processing shown in FIG. That is, when an interrupt occurs, the first character of output buffer 31 Is read (S10), and is temporarily fed to the RAM 22. If the read character is not a block end code (end-of-block) or a conversion delimiter, and conversion cannot be performed using only the data that has been read, interrupt processing is terminated and mail processing is terminated. The process returns to the routine (S11). If characters are continuously input to the output buffer 31, the interrupt is again activated when returning to the main routine, and the processor 20 executes the processing of FIG. 3 again. Then, the end code (end-of-block) of the block, the delimiter of the conversion, and the like are identified. The format of the data is converted (S12), and the data obtained by the conversion is sent to the input buffer 32 character by character, and the process is terminated (S13).
N C用プロセッサ 1 は出力バッファ 31に文字を書込んだ後は 入力バッファ 32にデータがセッ トされるのを待つ伏態となり ( S 4 ) 、 入力バッファ 32に 1文字でもデータがセッ ト されると これを読込み （ S 5 ) 、 1 ブロック分のデータが確定したとき に （ S 6 ) ステップ S 7 へ移行し、 数値制御ゃプログラムの登 録を実行する。  After writing a character to the output buffer 31, the NC processor 1 is in a state of waiting for data to be set to the input buffer 32 (S4), and even one character is set to the input buffer 32. Is read (S5), and when the data for one block is determined (S6), the process proceeds to step S7, and the numerical control program is registered.
このよう に変換の必要なデータがある場合、 従来の如く 1 2 8文字蓄積してから送出するのではな く 、 変換すべきデータが 発生すれば直ちに 1文字ずつプログラマブルコ ン ト ローラに送 出し、 また変換後のデータも従来の如く 1 2 8文字罠積してか ら送出するのではな く 、 変換が終了すれば直ちに 1 文字ずつ数 値制御装置側に返送するので、 数値制御装置の待ち時間は従来 より短く なり、 例えば数値制御中にカツタが一時的に不要に停 止する等の不都合が解消されるものとなる。 If there is data that needs to be converted in this way, instead of storing 128 characters before sending it out as before, instead of sending out the data to be converted, it sends the data to the programmable controller one character at a time as soon as it occurs. Also, the converted data is not sent after trapping the 128 characters as in the past, but is sent back to the numerical controller one character at a time as soon as the conversion is completed. The waiting time is shorter than before, for example, the cutter stops temporarily during numerical control. Inconveniences such as stopping are eliminated.
以上説明したように、 本発明によれば、 数値制御装置からは 変換の必要なデータを 1文字ずつ工作機械用プログラマブルコ ン ト ローラに送出し、 工作機械用プログラマブルコ ン ト ロ—ラ では変換の終了したデータを 1 文字ずつ数値制御装置に返送す るので、 従来のように ] 2 8文字毎にフォーマツ 卜変換すべき データ或はフォーマッ ト変換後のデータを授受していた場合に 比べ、 数値制御装置におけるフォ—マツ ト変換のための待ち時 間が短く なる効果がある。 *  As described above, according to the present invention, the data required for conversion is sent from the numerical controller to the programmable controller for the machine tool one character at a time, and the data is converted by the programmable controller for the machine tool. The completed data is returned to the numerical controller one character at a time, so that the data to be format-converted every 28 characters or data after format conversion is sent and received as in the past. This has the effect of shortening the waiting time for format conversion in the numerical controller. *
