Abstract
A can coating machine control system includes a coating control signal that functions as a go/no-go signal based on a plurality of monitored conditions such as can in position, vacuum pressure, gun in position, guard in position and speed condition. Local pressure regulation of the coating material in the spray gun is provided along with optional control of the material temperature. Local pressure regulation allows for optional spray weight control based on a wrap number derived from speed and gun spray-durations. A CAN to CAN network buffer is provided as well for primary network isolation. A gun control circuit may be used to select specific gun drive signals and to adjust gun drive signals based on real-time feedback of the actual spray duration.
