Multi-Specification Container Rapid Detection Adaptation for Filling Volume Inspection HV Supplies

Abstract This article presents HV supply optimization to enable rapid adaptation to multi-specification containers in filling volume inspection systems, which use X-ray attenuation to verify liquid/gas filling accuracy.
Introduction Filling lines (e.g., beverage, pharmaceutical) handle containers ranging from 100mL bottles to 20L drums. Traditional HV supplies require manual parameter adjustment when switching container specs, causing production downtime (>30min) and reduced efficiency.
Technical Challenges Key adaptation issues: 1) Fixed X-ray intensity (controlled by HV) unable to compensate for different container materials (plastic, glass, metal) and thicknesses; 2) Slow voltage switching (>5s) leading to production delays; 3) Lack of automatic spec recognition, relying on operator input.
Optimization Strategies Adaptive HV supply design:
1.Parameter Preset Library: Store 50+ common container specs (material, volume, thickness) with corresponding HV parameters (e.g., 80kV for 500mL plastic bottles, 120kV for 10L metal drums), enabling one-click switching.
1.Fast Voltage Regulation: Use a silicon carbide (SiC) HV module with <1s switching time between 50–150kV, reducing downtime to <5min.
1.Automatic Spec Recognition: Integrate a machine vision sensor to identify container dimensions and material, triggering automatic HV parameter adjustment without operator input.
1.Dynamic Attenuation Compensation: Real-time adjust HV output based on X-ray transmission data, ensuring consistent detection accuracy (±0.5% volume error) across specs.
Application Validation Tests on a beverage filling line showed:
Production efficiency increased by 25% (from 300 to 375 bottles/min) when switching between 355mL and 2L bottles.
Volume detection accuracy maintained at ±0.3% across all tested container specs.
Conclusion The adaptive HV supply enables rapid multi-spec container detection, improving filling line flexibility and productivity.
