Abstract
An apparatus is provided for spray coating an article and includes a housing defining a spray chamber. A spray gun is mounted on the housing for spray coating the article in the spray chamber. A shroud is disposed about the spray gun and defines an air passage between an inside of the shroud and an outside of the spray gun. Heated air is passed through the passage to heat the spray gun and, thereby, heat a coating material passing through the spray gun. A system includes a curing apparatus whereat the article, with the spray coating thereon, is finished by curing the spray coating. The curing apparatus creates an amount of heated air which is fed to the shroud.
Claims23
An apparatus for spray coating an article, comprising:
- a housing defining a spray chamber;
- a spray gun mounted at the housing for spray coating the article in the spray chamber;
- a shroud about at least a portion of the spray gun and defining an air passage between an inside of the shroud and an outside of the spray gun;
- and
- means for passing heated air through said passage to heat the spray gun and, thereby, heat a coating material passing through the spray gun.
A spray coating apparatus, comprising:
- a spray gun for spray coating an article;
- and
- a shroud about at least a portion of the spray gun and defining an air passage between an inside of the shroud and an outside of the spray gun,
- whereby air can be passed through said passage to control the temperature of the spray gun and, thereby, control the temperature of a coating material passing through the spray gun.
An apparatus for spray coating an article, comprising:
- a housing defining a spray chamber and including a downwardly sloping top wall having an opening;
- a spray gun extending through the opening in the top wall of the housing for spray coating an article in the spray chamber;
- and
- said opening being generally teardrop-shaped to define a relatively narrow upper edge and a relatively wide lower edge to prevent droplets from forming along the edges of the opening.
A system for spray coating and finishing an article, comprising:
- an apparatus for spray coating an article including
- a housing defining a spray chamber, and
- a spray gun mounted on the housing for spray coating the article in the spray chamber;
- a curing apparatus whereat the article with a spray coating thereon is finished by curing the spray coating with the curing apparatus creating an amount of heated air;
- and
- conduit means for directing the heated air from the curing apparatus to the spray gun of the apparatus for spray coating the article.
