Introduction
Analysis of the core content of the standard
| Test items | Test accuracy | Detection rate requirement | Typical defect examples |
|---|---|---|---|
| Bottle sealing surface defects | Volume＞5×3×2mm | ≥99.8% | Notch, crack |
| Foreign matter at the bottom of the bottle | Area＞3×3mm | ≥99.5% | Black rubber strip simulating dirt |
| Mold spots on bottle wall | Area＞4×4mm | ≥99.5% | Transparency＜30% area |
Key technical requirements
The standard stipulates that the bottle inspection machine must meet the inspection capacity of 36,000 bottles/hour, and also requires:
- Bottle loss rate＜0.001%
- Continuous rejection capacity≥50 defective bottles
- Total false detection rate≤0.5%×number of functional items
Taking beer bottle inspection as an example, it is necessary to simultaneously realize bottle mouth sealing surface, bottle bottom foreign matter, and residual liquid and other 6 detection functions, the total false detection rate must be controlled within 3%.
Standard Implementation Recommendations
1. Equipment selection: Select the corresponding model according to the bottle type (cylindrical/square), such as UJK Y-KD36 for cylindrical bottle special bottle inspection machine
2. Verification method: Use Appendix A standard test bottle, test each defect type ≥1000 times to ensure the detection rate meets the standard
3. Maintenance points: Regularly calibrate the optical detection unit, and the compressed air must meet the solid particle level 7 (GB/T 13277.1)
