Robot TEMA Multi - TEMA Mono for Coil Top-Side
Green Project offers robot solutions for marking coils using as spraying device:
- a TEMA Multi unit, marking characters defined by a dot matrix for applications requiring a fast marking cycle, or
- a TEMA Mono unit, whose opening synchronised with the robot movement produces characters defined by a continuous line (like written by a human hand), 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.
Main Marking Features
- Cold and Hot application up to 1100 °C
- Coil orientation: axis vertical or horizontal (parallel or perpendicular to coil transport)
- Marking position: on the cylindrical surface (along the coil axis or circumferential) on the flat surface (along a straight or curved line)
- Symbols: letters, numbers, special characters (logos), Data Matrix code
- Height of symbols from 28 mm to 200 mm, in one or more lines
- For TEMA Multi, fonts based on dot matrix: 7, 9 or 12 dots in height
- For TEMA Mono, standard and OCR fonts, based on a continuous line, are available
System configuration
- Six-axes Robot
- One TEMA Multi / 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
Automatic adapting to different coil dimension
Many parameters can be adjusted / selected by the operator via Control Unit, f.i.:
- Dot dimension (4 – 12 mm, automatically adjusted to coil temperature) (only TEMA Multi)
- Characters dimension (width, compression, height)
Host connection (Ethernet, Profibus or other common industrial fieldbus)
Optional functions
- Automatic Skipping of straps.
- Tools for editing fonts and modifying parameters (only TEMA Multi)
- Marking a Data Matrix code readable by a standard reader (combined marking / reading function to achieve automatic tracking of coils)
Paint / Ink features
Type:
cold : paint (solvent or alcohol base), ink (MEK or alcohol base)
hot : paint (solvent or water base)
cold for re-heating: special paint resisting to re-heating up to 750°C (for aluminium)
Colour: white (other colours available for cold applications)
Consumption: approx.10 g for 1000 dots (about 60 chars 70mm high)
