Abstract
A contactless monitoring system detects operating performance of movers in an independent cart system. A contactless sensor is provided on an actuator to automatically track a mover as it travels along the track. The sensor includes a transmitter configured to transmit a signal and a receiver configured to receive the signal after it is reflected off the mover. The actuator may be configured to mover the sensor in a single axis or in multiple axes of motion. As a mover travels along the track, the sensor transmits a signal towards the mover and detects the signal after it has been reflected off the mover. A controller may synchronize motion of the actuator with motion of the mover, such that the sensor may continually transmit the signal off the mover for at least a portion of the travel by the mover along the track.
