ABSTRACT:
An article monitoring and reject apparatus is disclosed that is particularly well suited for monitoring or inspecting glass containers and automatically rejecting defective containers. The system includes a monitoring unit having a plurality of scan diodes and associated phototransistors with each diode being individually caused to emit a plurality of light pulses and the diodes being successively energized to scan that portion of the article to be monitored. The associated phototransistor produces a plurality of electrical pulses when a defect is sensed, as indicated by light reflected from the portion of the article then being monitored, and a defect signal is produced only if a predetermined plurality of pulses are generated from each of a plurality of diodes indicative of a defect. An inspection window is established by a separate light emitter and sensor at the monitoring area and the signal produced is processed in dual paths to reject device circuitry. A reject sensor is also provided by a separate light emitter and sensor and a signal therefrom is coupled to the reject circuitry which enables automatic rejection of an article sensed to be defective.
