Abstract
An ultraviolet bottom coating system including a conveyor mechanism configured to route a plurality of cans in a machine direction, wherein the plurality of cans each have a bottom surface and uncured coating material applied on the bottom surface. The system also includes at least one ultraviolet light-emitting diode (UV-LED) device configured to emit ultraviolet radiation towards the plurality of cans, wherein the ultraviolet radiation is configured to cure the uncured coating material onto the bottom surface.
Claims13
An ultraviolet bottom coating system comprising:
- a conveyor mechanism configured to route a plurality of cans in a machine direction, wherein the plurality of cans each have a container portion including a bottom surface and a cylindrical body extending therefrom;
- a coating applicator defining a coating zone on the conveyor mechanism, wherein the coating applicator is oriented above the conveyor mechanism to apply the uncured coating material directly across the bottom surface of the plurality of cans as the plurality of inverted cans are routed through the coating zone;
- at least one UV-LED (ultraviolet light-emitting diode) device configured to emit ultraviolet radiation only having a wavelength defined within a range between about 315 nanometers (nm) and about 400 nm towards the plurality of cans, wherein the at least one UV-LED device is configured to emit the ultraviolet radiation at a power output defined within a range between about 2 Watts per square centimeter (W/cm2) and about 24 W/cm2, and wherein the conveyor mechanism is configured to orient the bottom surface towards the at least one UV-LED device, and wherein the ultraviolet radiation is configured to cure the uncured coating material onto the bottom surface, such that the cured coating material produces a clear finish on the cans when cured, the at least one UV-LED device comprising a cooling fluid inlet port and a cooling fluid outlet port;
- and
- a cooling fluid supply coupled in communication with the cooling fluid inlet and outlet ports of the at least one UV-LED device to channel a cooling fluid through the at least one UV-LED device.
