ABSTRACT:
A system for the reject of a single container from a row of multiple closely spaced containers on a moving conveyor. A circuit supplies a signal to a reject mechanism which is a solenoid actuated air blast to remove the container accurately. The circuit combines a shift register output with blanking signals in a first gate and a container position control sensing signal with the output of the first gate in a second gate to produce the appropriate reject signal. Mechanical fine tuning is provided to enable positioning the container signal within the appropriate time window.
