Application
The servo-based RS 5480 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 5480 ideal for 24/7 production.

Features
An RS 5480 is a servo-based screen printing machine for decorating items such as cosmetic jars. The RS 5480 features a rotary indexing ring designed for heavy duty use; the ring has 14 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 jars is made possible; for example, a wrap-around can be printed onto a square jar that has rounded corners.

A jar can be oriented to ensure a correct positioning of an image; a black/white camera (option) can detect a notch in the thread. Any necessary angular advance or retard for positioning an image on a jar is set at the touch screen.
