Abstract: A system and method 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. For monitoring the usage of powder paint particles, or “powder”, applied to the articles, the system and method sense a parameter associated with the amount of, or weight of, the powder in the powder delivery apparatus and displays it in real time as a powder-weight function over a period of time. For monitoring the operation of the conveyor line transporting the articles, the system and method sense the conveyor line speed and displays it in real time as a line-speed function over a period of time. For monitoring the precleaning-surface activation of the articles, the system and method sense the pH of the cleaning-surface activation solution and displays it in real time as a pH function over a period of time.

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.
