発明 の背景技術  BACKGROUND OF THE INVENTION
近年マ シ ニ ン グセ ン タ や タ ーニ ン グセ ン 夕 の よ う なェ 作機械は多品種少量生産に対応す る た め、 多種の加工プ ロ グラ ムが実行で き る よ う に な っ て い る 。  In recent years, machine tools such as machining centers and turning centers have been adapted to small-lot production of many types of products, so that various types of machining programs can be executed. What is it.
上記の よ う な工作機械で は、 自動搬入 さ れた ワ ー ク が こ れ力、 ら実行 さ れよ う と す る 加工プ ロ グラ ム に適 さ な い も の の場合、 ワ ー ク が工具や工作機械本体な ど と千渉 し て両者が損傷す る 虞れがあ る。 こ の た め、 自動搬入 さ れ た ワ ー ク が こ れか ら 実行 さ れ る 加工プ ロ グラ ム に適 し て い る かど う かを識别す る 必要があ る。  For machine tools such as those described above, if the automatically loaded work piece is not suitable for the machining program to be executed with this force, the work piece However, there is a possibility that both may be damaged due to collision with tools and machine tool bodies. For this reason, it is necessary to know whether or not the automatically loaded work is suitable for the machining program to be executed.
そ こ で従来で は上記 ワ ー ク の識別を例え ば第 1 図 に示 すよ う に ワ ー ク a を搬入す る パ レ ツ ト b に識別用 の複数 個の ド ッ グ c を設けて、 こ れ ら の ド ッ グ c を工作機械本 体 d 側に設け た複数個のセ ン サ e に よ り 検出 し た り 、 昭 和 6 1 年 日 本実用新案公開第 1 4 1 0 5 8号公報に記載さ れた 識別装置の よ う に、 ワ ー ク ホ ルダが取付け ら れた円扳状 プ レ ー ト に多数の ワ ー ク 識別 ド ッ グを設けて、 こ れ ら の ド ッ グを 夕 ツ チセ ン サで検出す る よ う に し た も の な どが すでに公知であ る。 Therefore, in the past, for example, as shown in Fig. 1, a plurality of identification dogs c were provided on the palette b for carrying in the work a as shown in Fig. 1. These dogs c are detected by a plurality of sensors e provided on the machine tool main body d side, and the Japanese Utility Model Publication No. 14410 in 1986 is shown. 58 No. 8 As in the case of the identification device, a number of work identification dogs are provided on a circular plate on which the work holder is mounted, and these dogs are placed in the evening. The ones that can be detected by the sensor are already known.

As the number of sensors to be detected increases, the equipment itself becomes complex and expensive, and the operator selects and operates multiple dogs according to the work. However, there was a problem that an operator could easily make a mistake in the determination of a work due to a simple mistake.

好ま し い具体例の詳細な説明  Detailed description of preferred examples
以下、 添付の図面 （第 2 図乃至第 1 6 図） に関連 し て 本発明の好ま し い幾つかの具体例が説明 さ れ る 。  In the following, some preferred embodiments of the present invention will be described with reference to the accompanying drawings (FIGS. 2 to 16).
先ず、 第 2 図及び第 3 図 に関連 し て本発明の第 1 具体 例を説明す る 。  First, a first specific example of the present invention will be described with reference to FIG. 2 and FIG.
図 に お い て 1 は図示 し な い工作機械に よ り 加工 さ れ る べ き ワ ー ク 2 を固定す る た めの治具で、 こ の治具 1 に取 付け ら れた ワ ー ク 2 を識別す る た めの特定の基準 プ ロ ッ ク 3 が取付 け ら れてお り 、 こ の基準ブ ロ ッ ク 3 が工作機 械本体に装備 さ れて い る 自 動寸法測定装置 4 に よ り 検出 さ れ る よ う に な っ て い る。  In the figure, reference numeral 1 denotes a jig for fixing a work 2 to be machined by a machine tool (not shown), and a work attached to the jig 1. A specific reference block 3 for identifying block 2 is installed, and this reference block 3 is installed on the machine tool. The detection is performed by the device 4.
上記 自 動寸法測定装置 4 は加工 さ れた ワ ー ク 2 の寸法 を測定す る 接触子 5 を有 し て い て、 こ の接触子 5 に よ り 上記基準プ ロ ッ ク 3 の上面の高 さ H を検出す る こ と に よ り 、 治具 1 に取付け ら れた ワ ー ク 2 を識別す る よ う にな つ てい る 。 、  The automatic dimension measuring device 4 has a contact 5 for measuring the dimension of the processed work 2, and the contact 5 allows the automatic dimension measuring device 4 to measure the dimension of the upper surface of the reference block 3. By detecting the height H, the work 2 attached to the jig 1 can be identified. ,
ま た基準ブ ロ ッ ク 3 の上面の高 さ H は、 各治具 1 毎に それぞれ異な っ ていて、 以下の よ う に ワ ー ク 2 の識別が 行なわれ る よ う に な つ て い る 。  Also, the height H of the upper surface of the reference block 3 is different for each jig 1 so that the work 2 can be identified as follows. .
すな わ ち、 第 4 図 に示すフ ロ ー チ ャ ー ト を参照 し て作 用 を説明す る と 、 各治具 1 に取付け ら れた ワ ー ク 2 が 自 動搬入さ れて所定位置に固定さ れ る と 、 ま ず 自動寸法測 定装置 4 が基準ブ ロ ッ ク 3 の上方へ移動せ し め ら れ、 続 いて基準ブ ロ ッ ク 3 に 向か っ て移動せ し め ら れて接触子 5 に よ り 基準プ ロ ッ ク 3 の上面の高 さ H が検出 さ れ る 。 That is, when the operation is described with reference to a flowchart shown in FIG. 4, the work 2 attached to each jig 1 is automatically carried in, and Once it is locked in position, The positioning device 4 is moved above the reference block 3 and then moved toward the reference block 3 to be moved by the contact 5 to the reference block. The height H of the upper surface of the tool 3 is detected.
そ し て検出 し た高 さ Hが許容寸法以内か ど う 力、 （ H o — 厶 H ≤ H ≤ H o + 厶 H ? ) を判別 し 、 許容寸法以内で あれば、 自動搬入 さ れた ヮ ク 2 力《 こ れか ら実行さ れ る 加工プ ロ グラ ム に適す る も の と し て加工を開始 し 、 許容 寸法以外であれば適 さ な い も の と し て加工を停止す る 。  Then, if the detected height H is within the permissible dimension, the force (H-mem H ≤ H ≤ H ≤ Ho + um H?) Is determined, and if the height is within the permissible dimension, it is automatically loaded. Power 2 Starts machining as appropriate for the machining program to be executed from now on, and stops machining as unsuitable if it is not the allowable dimension. .
な お以上は 自動寸法測定装置 4 が上方 よ り ほぼ垂直方 向 に移動 し て検出す る場合であ るが、 本発明の第 2 具体 例 と し て、 自 動寸法測定¾置 4 が側方よ り 水平に移動す る場合 は、 基準ブ ロ ッ ク 3 は、 第 5 図及び第 6 図 に示 さ れる よ う に水平方向の長さ Hが測定 さ れ る よ う に取付け られ、 かつ 自 動寸法測定装置 4 の水平移動方向 に長 さ H が変え ら れ る よ う にすればよ い。  The above is the case where the automatic dimension measuring device 4 moves in a substantially vertical direction from above to perform detection, but as a second specific example of the present invention, the automatic dimension measuring device 4 is When moving horizontally, the reference block 3 is mounted so that the horizontal length H is measured as shown in FIGS. 5 and 6. In addition, the length H may be changed in the horizontal movement direction of the automatic dimension measuring device 4.
ま た第 7 図及び第 8 図に は本発明 の第 3 具体例が示 さ れ、 治具 1 に多種類の ワ ー ク 2 が取付け ら れて 自 動搬入 さ れ る場合の識別装置を示す も ので、 該装置の作用 を第 9 図に示すフ ロ ー チ ャ ー ト に よ り 説明す る と 、 治具 1 に 取付け られた ワ ー ク 2 が自動搬入 さ れて所定位置へ固定 さ れ る と 、 ま ず 自動寸法測定装置 4 が基準ブ ロ ッ ク 3 の 上方へ移動せ し め られて基準プ ロ ッ ク 3 の上面の高さ H を測定する。  FIGS. 7 and 8 show a third specific example of the present invention, which is an identification device in a case where various types of works 2 are mounted on a jig 1 and are automatically carried in. The operation of the device will be described with reference to the flowchart shown in Fig. 9. According to the flowchart, the work 2 attached to the jig 1 is automatically carried in and fixed to a predetermined position. Then, the automatic dimension measuring device 4 is first moved above the reference block 3 to measure the height H of the upper surface of the reference block 3.
そ し て検出 し た高 さ Hが許容寸法以内か ど う 力、 （ H o j Then, force to check whether the detected height H is within the allowable dimension, (H o j
— 厶 Η ≤ Η ≤ Η ο + Δ Η ? ) を判定 し て、 許容寸法以外 であればそ の後 に予定 さ れた加工を停止す る 。 — Judgment ≤ ≤ ≤ + Δ ο + Δ?), And if it is not the permissible dimension, stop the scheduled machining after that.
ま た許容寸法以内であれば 自 動寸法測定装置 4 を ヮ 一 ク 2 の上方へ移動 し て、 ワ ー ク 端面測定点の高さ h を測 定す る 。  Also, if it is within the allowable dimension, move the automatic dimension measuring device 4 above the work 2 and measure the height h of the work end face measurement point.
そ し て検出 し た ワ ー ク 端面高 さ h が許容寸法以内か ど う 力、 （ h o — A h ≤ h ≤ h o + A h ? ) を判定 し、 許容 寸法以内であ れば上記加工を開始 し 、 許容寸法以外であ ればそ の加工を停止す る 。  Then, the force (ho — Ah ≤ h ≤ ho + Ah?) Is determined to determine whether the detected work surface height h is within the allowable dimensions, and if the height is within the allowable dimensions, the above processing is performed. Start and stop the processing if it is not the allowable dimension.
こ の方法 に よ れば、 治具 1 に取付け ら れた ワ ー ク 2 が 直接検出 さ れ る た め、 治具 1 の基準ブ ロ ッ ク 3 を そ の都 度変更す る 必要がな く 、 従来の よ う に取付け ミ ス な どが 生 じ る お それがな い。  According to this method, since the work 2 attached to the jig 1 is directly detected, it is not necessary to change the reference block 3 of the jig 1 each time. In addition, there is no danger of mounting mistakes as in the past.
—方、 第 1 0 図な い し第 1 3 図 は治具 1 の別の具体例 を、 そ し て第 1 4 図な い し第 1 6 図 は ワ ー ク 形状に応 じ た測定点の違い を例 と し て そ れぞれ示 し た も のであ る 。  —Fig. 10 or Fig. 13 shows another specific example of the jig 1, and Fig. 14 or Fig. 16 shows the measurement points according to the work shape. The differences are shown as examples.

No.
さ ら に ワ ー ク 識別プ ロ グラ ム は ワ ー ク の加工を実行す る N C プ ロ グラ ム の前に置かれて実行 さ れ る が、 サブプ ロ グラ ム とす る こ と に よ り 毎回プ ロ グラ ム を作成す る 必 要はな い。  In addition, the work identification program is executed before the NC program that performs the machining of the work, but is executed by using a sub-program. You do not need to create a program every time.
