Abstract
This invention relates to coating systems and to methods and apparatus for coating containers and closures employing container and closure indexing machines having vacuum chucks mounted on the edge of one or more turrets rotating in horizontal or vertical planes about a stationary shaft for loading, spray coating, optionally curing and unloading can and can ends secured to vacuum chucks extending radially from the edges of the turret. Further, devices are provided for loading and unloading cans and can lids onto and off of a turret rotating in either the horizontal or vertical plane.
Claims14
An indexing machine for a coating system, comprising:
- a central, stationary shaft having first and second bores adapted for connection to a source of vacuum air pressure and to a source of positive air pressure, respectively;
- at least one turret rotatably disposed about said shaft for indexing therearound, said turret having a plurality of passageways and a plurality of vacuum chucks for supporting a product to be coated, each of said passageways communicating with an internal bore of one of said vacuum chucks, said passageways selectively communicating with said first and second bores as said turret rotates about said shaft.
An indexing machine for a coating system for containers or closures having at least one turret with multiple vacuum chucks rotating in a horizontal plane, comprising:
- means for loading said containers or closures of said vacuum chucks at a first station of said turret;
- means for applying a coating to said containers or closures at a second station of said turret;
- and
- means for unloading said containers or closures from said turret.
