When a metal detector misses, a number of steps need to be taken to troubleshoot the problem, fix the equipment and ensure the system is up and running. Here are some recommended steps to take to deal with missed metal detector detections:
Immediate Shutdown:
Stopping the machine as soon as a missed inspection is detected can prevent the defective product from continuing through the production line and reduce the number of missed inspections.
Flag problematic products:
Flag problematic products for subsequent detailed inspection and analysis.
Check your device settings:
Check the metal detector settings and parameters to ensure they are adjusted correctly, check settings such as sensitivity, frequency, etc., to ensure they are suitable for the current product and production conditions.
Check the conveyor belt or conveyor system
Inspect conveyor belts or conveyor systems to ensure that products are passing through the metal detector without any issues, as issues with the conveyor system can lead to missed detections such as zone deviation, speed mismatch, etc.
Check the detector:
Carefully inspect the detector of the metal detector for any damage, loosening or foreign objects to ensure that the detector is in good working order.
Check product characteristics:
Understand the characteristics of the products currently being produced, including shapes, sizes, materials, etc., and ensure that the metal detector is set up to accommodate these characteristics.
Take the test:
Conduct system testing with samples known to contain metallic foreign objects to ensure that the metal detector can accurately detect these samples.
Adjust sensitivity and settings:
Based on the test results, the sensitivity and other relevant settings of the metal detector are adjusted to improve its detection performance.
Training Operators:
If the missed detection issue is related to the operator, provide training to ensure they understand the correct use of the equipment.
Scheduled Maintenance:
Implement a regular maintenance program that includes cleaning detectors, inspecting conveyor belts, calibrating equipment, etc., to ensure that your metal detector remains in good working order for a long time.
Recording and analyzing data:
Record the details of each missed check and analyze the cause of the missed miss so that you can develop a long-term improvement plan.
When dealing with metal detector misses, problems need to be identified promptly and thoroughly and corrective action to ensure product quality and safety.
