The signal 1c is directly input to the force sensor receiver board 2a and the posture angle receiver board 2b of the teaching information generation unit, and the operation force and the initial posture angle are calculated by the internal computer 2c. The internal computer 2c transmits the operating force, the initial posture angle, and the direct teaching permission signal 1a to the robot by real time communication means. In the industrial robot that has received the operation force and the initial posture angle, the operation force coordinate conversion unit 4a generates the operation force information considering the posture of the robot arm using the operation force and the initial posture angle information, and directly teaches the controller. 4b, the direct teaching controller 4b finally performs the teaching follow-up operation of the robot based on the input operation force information.
The teaching permission signal switch 12 generates a teaching permission signal for permitting teaching control to an industrial robot to be directly taught. That is, the robot is switched from the normal operation control or the control stop state to the teaching control state by the teaching permission signal. The direct teaching information generation unit transmits teaching information (force information and handle posture angle information) to the robot side in conjunction with the teaching permission signal, or always transmits teaching information regardless of the teaching permission signal.
このように構成された、一つの直接教示モジュールと複数の産業用ロボットからなる直接教示システムにおいては、教示すべき１台の産業用ロボットのアーム先端部分の姿勢調整機構部に教示ハンドル部をオペレータが操作しやすい所望の姿勢角で取り付け、直接教示を行う。教示が終了すれば、教示ハンドル部を取り外し、次の他の教示すべき産業用ロボットのところに直接教示モジュールを移動し、同様に当該他の教示すべき産業用ロボットのアーム先端部分の姿勢調整機構部に教示ハンドル部を所望の姿勢角で取り付けて直接教示を行う。このようにして、一つの直接教示モジュールを備えるだけで、システム内の複数のロボットの全てに対して直接教示が行える。 In the direct teaching system composed of one direct teaching module and a plurality of industrial robots configured as described above, the teaching handle portion is attached to the posture adjustment mechanism portion of the arm tip portion of one industrial robot to be taught. Attaches at a desired posture angle that is easy to operate and teach directly. When teaching is complete, the teaching handle is removed, the teaching module is moved directly to the next other industrial robot to be taught, and the posture of the arm tip of the other industrial robot to be taught is similarly adjusted. A teaching handle portion is attached to the mechanism portion at a desired posture angle and teaching is performed directly. In this way, it is possible to directly teach all of a plurality of robots in the system only by providing one direct teaching module.
