    摘要: A numerical control system comprising a numerical control device, a machine tool for machining a workpiece under the control of the numerical control device, and a robot for executing various tasks such as mounting the workpiece on the machine tool or demounting the workpiece therefrom. The numerical control device, in addition to the hardware which it possesses for controlling the machine tool, is further provided with a teaching control panel, a heavy current circuit which handles the exchange of data between the numerical control device and the robot, and a switching control circuit for switching over the output side of a pulse distributing circuit so that the pulse distributing circuit can be used in controlling both the robot and the machine tool. Machining data for control of the machine tool and data for commanding the robot are stored in a memory device incorporated in the numerical control device, or in a storage medium which is located externally of the system. The stored data can be read out in succession to designate the machine tool, which will then perform a machining operation, or to designate the robot which will respond by executing a prescribed task or tasks.

    摘要: The hand of a robot is moved from an instant position P.sub.1 to a first command position P.sub.2 to grip one of the workpiece W.sub.1,W.sub.2,W.sub.3 placed at the first command position and conveys the same to a second command position P.sub.3. A sensor is contacted by the workpiece when the hand takes an intermediate position Px on its way from the instant position P.sub.1 to the first command position P.sub.2, the robot control system stops the hand without delay or after travel of the hand over a predetermined distance and, after the travel of the hand over a predetermined deceleration distance, stops the hand. The hand is then moved from the stopping position to the second command position P.sub.3 neglecting the remaining stroke or movement between the stopping position and the first command position.
