Abstract
An automated paint-batching system for producing paint cans of any size and color. The system includes a plurality of paint-batching cells, with each cell having a machine comprised of either one or two dispensing stations. When two dispensing stations are used, the two dispensing stations are: A first tint-station, where a small volumetric dispensing of the base, water-base or oil-base, of the paint is dispensed, in order to wet the bottom of the can, at the first station, thereafter, is dispensed all of the liquid colorants making up the formula of the paint can, and a second base-dispensing station at which the remainder of the base of the formula of the paint is dispensed. Each of the first and second stations of the paint-batching machine of the invention has operatively associated therewith a weighing platform upon which rests the paint can during the dispensing at the respective station used in quality-control weighing of each dispensing. When only one dispensing station is used, all of the above-steps are performed at the one station. Each paint can has attached to it a bar-code label which represents a relocatable memory-address of the computer which stores the color-formu…
