Machine for drying inks of the UV type

A method for drying inks of the UV type, the method including the following steps:

• positioning an object to be processed, which bears inks of the UV type to be dried printed thereon, on a pan rotatably supported by a carriage and arranged in an access position,
• moving said carriage to bring said supporting pan to an exposure position, in which said supporting pan is arranged inside an exposure chamber,
• rotating said supporting pan,
• activating a UV radiation emission source accommodated in said exposure chamber to expose the inks of the UV type to be dried to UV rays emitted by said emission source, and
• moving said carriage to bring said pan from said exposure position to said access position:
• unloading said processed object from said at least one supporting pan by means for an automatic unloading of the processed object from said at least one supporting pan, configured to be activated on command with said at least one supporting pan in said access position, wherein said automatic unloading means comprise pusher means adapted to produce, on the processed object arranged on the corresponding supporting pan, a thrust in the direction of a respective unloading chute.

A machine for drying inks of the UV type, the machine comprising:

• a supporting frame, which forms at least one exposure chamber, configured to be accessed from the outside and accommodates at least one UV ray emission source, further comprising, on said supporting frame, at least one carriage which supports rotatably at least one supporting pan for supporting at least one object to be processed which is provided, on a surface thereof, with at least one print provided by UV inks, means for rotational actuation of said at least one supporting pan about an axis thereof being provided to rotate said at least one object to be processed, said carriage being movable with respect to said supporting frame to move said at least one supporting pan from an exposure position, in which said at least one supporting pan is arranged within said exposure chamber, to subject the UV inks applied to the object to be processed to an action of the UV rays emitted by said at least one emission source, to at least one respective access position, in which said at least one supporting pan is arranged outside of said exposure chamber, to allow a loading of said at least one object to be processed on said at least one supporting pan or an unloading of the processed object from said at least one supporting pan, said rotational actuation means being activatable on command at least with said at least one supporting pan in said exposure position, and further comprising means for an automatic unloading of the processed object from said at least one supporting pan, configured to be activated on command with said at least one supporting pan in said access position, wherein said automatic unloading means comprise pusher means adapted to produce, on the processed object arranged on the corresponding supporting pan, a thrust in the direction of a respective unloading chute formed on said supporting frame.
