Pneumatic Safety in Robot Cells
Invisible energy causes visible injuries.
Measures
- Release pressure and lock the supply before maintenance.
- Define gripper behaviour on air loss: hold or release, decided deliberately.
- Filter and drain the air supply to prevent erratic operation.
- Secure hoses against wear and whipping.
Common hazards
| Hazard | Consequence |
|---|---|
| No bleed point | Residual pressure injures maintenance staff |
| Loss of air releases the part | Dropped workpiece |
| Valve failure | Unexpected continuous motion |
