Application The servo-based RS 7480 is designed for multi-colour decoration with UV inks of glass or plastic items at high production speeds; servo drives for screens and fixtures reduce changeover times. Reliability and speed make the RS 7480 ideal for 24/7 production. Features An RS 7480 is a servo-based screen printing machine for decorating items such as cosmetic jars. The RS 7480 features a rotary indexing ring designed for heavy duty use; the ring has 18 stations, each has a station head with a fixture. A servo screen printing machine is required to screen print onto complex shaped items that have cross sections with linear, circular and oval elements. An advanced motion controller synchronises the print movements of four servo-driven axes in each printing station: print head with screen and squeegee, screen, squeegee, and fixture. The simultaneous movements of print head, screen, squeegee, and fixture during printing ensure that the squeegee edge stays in contact with the printing area. One-pass multi-colour printing onto complex-shaped bottles or glasses is made possible; for example, a wrap-around can be printed onto a square bottle that has rounded corners. An item can be oriented to ensure a correct positioning of an image. Any necessary angular advance or retard for positioning an image on a bottle is set at the touch screen.
