Issue
The existing inspection system being in use for many years was aging and led to more false detections found than ever before. Additively specifications not outputting detection values on its inspection screen brought particular concerns in recent years.
Solution
In response to plans to upgrade plant equipment to improve productivity in the same period, we proposed an inspection system accommodating wide horizontal production equipment.
Background：Increasing number of inspection errors in metal detectors used for many years.
After nearly 20 years of use, the detector obsolete in recent years and gave false positives (misclassification of good products). Good products not containing foreign bodies were being detected as defective, and sorting of defective products was becoming lax, and this led to a negative impact on production.
Reason of installation：Concern that the detection values are not displayed on the screen of the existing detectors.
Differences in detector's operability surprised us visiting a group company's plant. Doubts about the settings in the current operation made us uneasy, as We had never seen the detection values on screen. Increases in false positives due to ageing and the resulting food losses of several kilograms per day were forcing us to take action.
How it works：Enhanced productivity through the introduction of inspection detectors that match new production equipment.
Suitable detectors, suggested for wider production lines to improve productivity, pleased us, improved inspection accuracy, reduced false positives and stabilised production. Further reduction in food loss gave us delight.
*Example of inspection accuracy: improved from Fe Φ1.2 mm to 0.8 mm and SUS Φ2.0 mm to 1.2 mm.
