A packaging line does not tolerate a slow inspection step. Whatever you check, a cap, a label, a seal, a printed date, it has to be checked at line speed and rejected without breaking throughput. The worry with adding AI is that it will become the bottleneck. A real deployment shows it does not have to.
How fast, and how accurate, in a real cell?
On a live cap-inspection line, an Adente Vision unit rejects broken, unclosed and hinge-damaged caps as they pass. The measured result is a 99.65% F1-score with a 0.69% false-negative rate at about 30 ms per part. The false-negative rate is the one to hold onto: it is the escape rate, the bad packs that get through, and 0.69% is the figure to demand from any vendor. Throughput of 100+ parts per minute is a conservative catalog bound. For why that metric matters more than headline accuracy, see the inspection metric vendors don't advertise.
Which checks, which trigger, which reject
| Check | Trigger | I/O action |
|---|---|---|
| Broken / unclosed / hinge-damaged cap | Photoelectric or encoder | Reject on a 24V output |
| Label placement and skew | Photoelectric part-present | Reject on a 24V output |
| Print and date / batch code | Encoder-locked capture | Reject on a 24V output |
| Seal presence | Photoelectric part-present | Reject on a 24V output |
| Correct count in a pack | Fixed interval or encoder | Count and pass/fail to the PLC |
The unit triggers from a photoelectric sensor, the line encoder or a fixed interval, so it catches the part in frame whatever the line type, and an up-to-12 MP global-shutter sensor freezes it without smear. A fail drives one of the 4 discrete 24V outputs to a reject actuator, with the delay from inspection point to reject point tracked so the right part is removed.
IP54 or IP65, and who installs it?
A dry packaging line uses the AV-S100 (IP54). A line that gets hosed down, which is most food, beverage and pharmaceutical packaging, needs the washdown AV-W100 (IP65); the sector case for that is in food and beverage vision inspection. Both run identical optics and AI. Adente Vision is an edge-AI visual inspection unit built by ADENTE Advanced Engineering Technologies, part of the Aden Group, sold through automation system integrators, so the integrator who builds your packaging line adds inspection as a line item and keeps the account.
