ABSTRACT:
A sensor circuit in a system for automatically coating objects with a coating material wherein the coating material is discharged onto objects moving in a path relative to a discharge station in response to a control signal. A sensor detects the presence of an object at a point along the path upstream of the discharge station and produces an object detection signal which is processed by the sensor circuit to produce a sensor signal. The sensor signal is used by a timing and driver circuit to provide a delayed control signal to the coating material discharge apparatus, after an appropriate delay, for a desired duration. The sensor circuit includes an integrator for integrating the object detection signal produced by the sensor and a trigger circuit coupled to the integrator for providing a substantially rectangular wave output derived from the integrated object detection signal. The rectangular wave output is coupled to the timing and driver circuit to produce the delayed control signal for the discharge of the coating material.
