Abstract
A curing station for curing printing ink of a direct print on containers, comprising a conveyor for conveying the containers preferably in container holders, and further comprising at least one UV light unit for curing the printing ink, characterized in that the at least one UV light unit comprises a 2D arrangement of UV LEDs for generating a UV light field for curing the printing ink.
Claims14
A curing station for curing printing ink of a direct print on containers, comprising:
- a conveyor for conveying the containers;
- and
- at least one UV light unit for curing the printing ink, wherein the at least one UV light unit comprises a 2D arrangement of UV LEDs for generating a UV light field for curing the printing ink,
- wherein the UV LEDs of the at least one UV light unit are configured to be controllable individually or in groups, so as to control the UV light field depending on conveyance positions of the containers relative to a curing and/or pinning section of the curing station, the curing station further comprising a control unit configured to change the UV light field by controlling an output of at least one of the UV LEDs, and
- wherein the control unit is configured to change the outputs of the UV LEDs on a basis of conveyance positions of the containers relative to a curing and/or pinning section of the curing station, so as to cause the UV light field to follow the conveyance of the containers.
2 more elements
A method of curing printing ink of a direct print on containers, comprising:
- conveying the containers;
- and
- curing the printing ink by means of at least one UV light unit during such conveyance, wherein the at least one UV light unit generates a UV light field for curing the printing ink by a 2D arrangement of UV LEDs,
- wherein the UV light units move along with the conveyance of the containers, and wherein the UV light fields are generated depending on conveyance positions of the containers relative to a curing section and/or pinning section of a curing station;
- or
- wherein the at least one UV light unit is arranged stationarily, and wherein the UV light field is caused to follow a conveyance movement of the containers by controlling the UV LEDs depending on the conveyance movement.
