Abstract (en)
[origin: EP0419833A1] What is described is a device for the contactless monitoring of a region (14) adjacent to a service robot (12) of a ring spinning machine (10), said device comprising an electroacoustic transducer (18). The transmitted sound signal supplied by the transducer (18) is divided into a measurement sound signal (SSM) and a reference sound signal (SSR). An electronic control unit (16) supplies a fault signal when no sound signal has been received by the expiry of a reference running time. On the other hand, if a sound signal is received before the expiry of the reference running time, the control unit (16) supplies a recognition signal. <IMAGE>
