Addressing Power, Air, and Mechanical Problems
System-level issues can halt production:
-
Machine Inoperable/Erratic: Caused by activated emergency stop, tripped main breaker/fuse, blown fuse, PLC fault/program error, faulty/blocked sensors (proximity/photoeyes), or low/no air supply. Solution: Reset E-stop, reset breaker, replace fuse, check PLC status/program/reboot/call OEM, inspect/clean/realign sensors, check air pressure (typically 0.5-0.7 MPa).
-
Slow/Non-Moving Cylinders: Results from low air pressure, kinked/leaking air hoses, overly restricted flow control valves, damaged cylinder seals, or faulty solenoid valves. Solution: Check/adjust air pressure, straighten/replace hoses, fix leaks, open flow controls, replace seals/cylinder, clean/replace solenoid valves.
-
Abnormal Noise: Caused by loose mechanical parts (screws, bearings), dry/worn drive components (chains, gears), or component interference. Solution: Tighten fasteners, lubricate drives, replace worn parts, eliminate interference points.
-
Inconsistent Performance: Stemming from power voltage fluctuations, air pressure fluctuations, drifting sensor sensitivity, intermittently loose components, or intermittent film roll jamming. Solution: Use voltage stabilizer, add air receiver/troubleshoot compressor, clean/adjust/replace sensors, check/tighten all fasteners, ensure smooth film roll mounting/rotation.
Vital Reminders:
-
SAFETY FIRST: Always isolate power and air before maintenance. Wait for moving parts/hot surfaces to stop/cool.
-
Consult Manuals: Refer to OEM manuals for specifics.
-
Systematic Approach: Start with basics: Power, Air, Film, Settings.
-
Observe: Note when and how the fault occurs.
-
Preventive Maintenance (PM): Regular cleaning, lubrication, inspection, and replacement of wear parts (blades, seals, filters, belts, bearings) is key to reliability.
-
Expert Help: Contact OEM/service for complex electrical, PLC, or major component issues.
