1. Purpose
The purpose of this Standard Operating Procedure (SOP) is to establish a systematic approach for troubleshooting aerosol filling machines. Effective troubleshooting helps minimize downtime, maintain product quality, and improve production efficiency.
2. Scope
This SOP applies to all aerosol filling machines used in production, including propellant filling systems, crimping machines, and product dosing systems. It covers troubleshooting of mechanical, pneumatic, and electrical issues.
3. Responsibilities
- Production Operators: Responsible for identifying and reporting machine faults.
- Maintenance Team: Responsible for diagnosing and resolving mechanical, pneumatic, and electrical issues.
- Quality Assurance (QA) Team: Responsible for verifying machine performance after troubleshooting.
- Engineering Team: Responsible for major repairs and preventive maintenance planning.
4. Accountability
The Maintenance Manager is accountable for ensuring timely troubleshooting, repair, and documentation of aerosol filling machine issues.
5. Procedure
5.1. Identifying Common Machine Issues
- Operators should monitor machine performance and identify issues such as:
- Propellant Filling Issues: Inconsistent fill weight, gas leakage, or valve malfunction.
- Product Dosing Problems: Underfilling, overfilling, or clogging.
- Crimping Malfunctions: Loose or improperly sealed valves.
- Machine Stoppages: Pneumatic or electrical failure.
- Conveyor System Failures: Misalignment or jamming.
- All issues should be recorded in the Machine Fault Log (Annexure-1).
5.2. Initial Troubleshooting
- The operator should
perform basic troubleshooting before calling the maintenance team.
For minor issues:
If the issue persists, escalate to the maintenance team.
- Check air pressure settings and ensure they match machine specifications.
- Inspect machine sensors and clear any obstructions.
- Verify that product and propellant supply lines are not blocked.
5.3. Mechanical and Pneumatic Troubleshooting
- Maintenance personnel should inspect:
- Seals, gaskets, and O-rings for wear and tear.
- Crimping dies and filling nozzles for alignment.
- Compressed air pressure and lines for leaks.
- If components are damaged, replace them as per the Equipment Repair Log (Annexure-2).
- Test machine functionality after repairs.
5.4. Electrical Troubleshooting
- For machines experiencing power failures or sensor malfunctions:
- Check fuses and circuit breakers.
- Inspect wiring connections for loose or damaged wires.
- Reset the control panel and check software settings.
- All electrical troubleshooting activities must be documented in the Electrical Maintenance Log (Annexure-3).
5.5. Quality Assurance Verification
- After repairs, the QA team should verify machine performance.
- Conduct test runs to ensure proper filling, crimping, and propellant charging.
- Record observations in the Machine Performance Verification Log (Annexure-4).
5.6. Preventive Maintenance
- Schedule regular machine inspections to reduce the frequency of breakdowns.
- Maintain an inventory of spare parts to minimize downtime.
- Update preventive maintenance records in the Maintenance Schedule Log (Annexure-5).
