SAFETY DEVICE FOR AUTOMATIC RUNNING DOLLY
Document Type and Number:
Japanese Patent JPS58107910
Kind Code:
A
Abstract:
PURPOSE:To ensure the safety at corners of a path, by providing a device detecting the presence of personnel at the corners of the path and controlling the movement of the dolly. CONSTITUTION:When a dolly 5 runs and intercepts rays 8a, since a dolly body detection signal 8A goes to H, a memory 13 is set and an AND gate 15 is closed. Further, a television camera 10 transmits a picture in a prescribed range 11 to a pattern recognizer 12, and when a personnel is detected through the pattern recognition, the output goes to H. An output of an AND gate 14 goes to H and a stop command signal 16a goes to H, then the dolly 5 is stopped suddenly. When the recognizer 12 does not detect a personnel, the output goes to L, the output of the AND gate 14 also goes to L, the dolly 5 is not stopped and advances a corner 1a in a curve. When the dolly 5 intercepts rays 9a, a dolly detection signal 9A goes to H, the memory 13 is reset and the output goes to L.
