Green Project offers robot solutions for marking plates at the exit of hot or cold strip mills, using as spraying device a single nozzle unit, whose opening synchronised with the robot movement produces characters defined by a continuous line (like written by a human hand) and very well readable also from distance.
Robot machines are more flexible than standard machines as they can be easily updated / modified in order to satisfy new marking requirements.

• Cold and Hot application up to 1100 °C
• Marking orientation: crosswise or lengthwise (perpendicular or parallel to plate transport)
• Static (plate stopped under marking machine)
• Marking position: on top surface
• Symbols: letters, numbers, special characters (logos), Data Matrix code
• Height of symbols from 28 mm to 200 mm, in one or more lines.
• Standard and OCR fonts, based on a continuous line, are available

• Six axes Robot
• One TEMA Mono marking head
• Paint preparation cabinet (including circuit for paint recirculation)
• Pneumatic cabinet
• Automatic cleaning system
• Power and control cabinet
• Work cell with safety fence
• Control desk with HMI
• For hot applications, the system is equipped with a kit for thermal protection

Functional features
Flexible automation functions assure precise positioning of the markings, symbols size automatically adaptable to plate width/length Many parameters can be adjusted / selected by the operator via Control Unit, f.i.:

• Characters dimension (width, compression, height)
• Frequency and duration of washing cycle

• Marking a Data Matrix code readable by a standard reader (combined marking / reading function to achieve automatic tracking of plates)

Paint / Ink features
Type:
cold : paint (solvent or alcohol base), ink (MEK or alcohol base)
hot : paint (solvent or water base)
Colour: white (other colours available for cold applications)
Consumption: approx.10 g for 1000 dots (about 60 chars 70mm high)
