Introduction
Analysis of the core content of the standard
| Detection module | Key indicators | Detection accuracy | Detection rate requirement |
|---|---|---|---|
| Cover detection module | No cover/high cover/skewed cover | Height difference>1.0mm | ≥99.5% |
| Liquid level detection module | High and low liquid levels | Offset>3mm | ≥99.5% |
| Standard inspection module | No label/high and low label | Offset>4mm | ≥99.9% |
Technology evolution analysis
This standard systematically specifies the all-round inspection requirements of liquid bottled packaging inspection machines for the first time. Compared with traditional inspection equipment, it adds:
- Anti-theft ring broken bridge detection (crack length>40% of the circumference)
- Label misalignment detection (offset>2mm)
- Inkjet character recognition system (character recognition types ≤50)
Implementation suggestions
Application case in the beverage industry
A brand of mineral water production line adopts UJPBPT-GYB60 inspection machine:
- Liquid level false detection rate reduced from 0.1% to 0.02%
- Label defect detection rate increased to 99.92%
- Achieved continuous rejection capacity of 1,000 bottles per minute
Key Terms Explanation
Continuous rejection capacity
Refers to the maximum number of defective bottles that the inspection machine can continuously reject under the rated inspection capacity, which directly affects the stability of the production line
Standard test bottle
Accurate defective sample bottle made according to Appendix A, used to verify the inspection accuracy (e.g., high-cap bottle requires a metal gasket with a thickness of >1mm)
