Abstract
A system for monitoring an electrostatic powder painting process having a conveyor line adaptable for transporting articles to be electrostatically powder painted sequentially through a plurality of zones in the process. The monitoring system dispenses powder paint particles from a delivery container through a conduit to an electrostatic powder paint spray gun used for applying the powder paint particles to the articles in a painting zone, and senses the weight of the delivery container and powder paint particles therein with a scale device. The scale device generates a paint weight signal corresponding to the real time weight of the delivery container and powder paint particles therein. The monitoring system transmits the paint weight signal from the scale device to a computer-monitor adaptable for displaying the real time weight of the delivery container and powder paint particles therein as a container weight function over a predetermined period of time. The monitoring system senses the speed of the conveyor line with speed sensor which generates a line speed signal corresponding to the real time line speeds and transmits the line speed signal from the speed sensor to the computer-monitor as a line speed function over a predetermined period of time.
