The integrated full‑bottle inspection machine Promita‑P One is an inspection device designed to meet the requirements of filling production lines, enabling more efficient, accurate and controllable production. It is suitable for on‑line inspection of filled bottles after filling on PET bottle production lines. It reliably inspects product liquid levels, bottle caps, inkjet codes and other features, and precisely rejects defective products to ensure product quality. In addition, it can be combined with a filling management system to realize traceability of defective products on the production line, conduct real‑time monitoring of production activities, and reduce production losses.

Cap inspection mainly checks for missing caps, high tilted caps, broken tamper rings and other defects. Inspection is split into two stages. The first stage, the SCI cap inspection module, is installed upstream of the filler to stop defective caps such as deformed, irregular and dirty caps from entering the production line. The second stage, the ACI 360° tamper ring inspection module, is mounted downstream of the filler to verify any abnormalities on caps after filling.
The SCI cap inspection module utilises one industrial colour camera to inspect cap appearance. Fitted onto the vacuum suction belt before the filler, it eliminates interference from cap slippage during conveyance. Defective items are ejected by a downstream air nozzle rejector after inspection.
The ACI 360° tamper ring inspection module is installed downstream of the filler. It mainly detects defects after capping and screwing, including high tilted caps, missing, deformed or broken tamper rings. The detection accuracy for high tilted caps reaches ±1 mm.
The ACI module features an elaborate optical path design. It captures images by dividing the cap’s 360° circumference into four 90° segments. Combined with Xispek’s high-efficiency image processing algorithms, it reliably identifies defects at any angle around the cap, ensuring every faulty cap is detected precisely.
It mainly checks the presence of coding marks and is compatible with all types of coders, including inkjet and laser coding equipment.
The code inspection unit consists of one high-speed industrial camera and maintenance-free LED light sources. Based on the principle that laser coding generates a local temperature far higher than ambient temperature at the moment of marking on caps or bottle bodies, high-precision temperature sensors measure the instantaneous temperature after coding to verify whether codes are printed in the designated area. It accurately identifies defects such as missing lines, missing characters and duplicate codes. The detection accuracy reaches 99.9% for fully missing codes or codes missing more than 70% of their area.
By combining the inspection system and real‑time tracking system, inspection statistics are linked to the positions of filling valves and capping heads inside the filling machine. Each filling head or other equipment requiring traceability is equipped with a photoelectric sensor. Triggering of the sensor creates an independent channel for product monitoring, which is closed upon rejection to realize complete tracking.
When the system detects frequent under‑filling from a certain filling valve or continuous tilted caps from a certain capping head, it actively alerts operators for targeted maintenance. This helps factories implement predictive maintenance, reduce downtime and improve production stability.
Custom sampling is also supported with flexible sampling rules (e.g., sampling 10 bottles from a specified filling valve or batch‑sampling all stations). The system automatically executes tasks upon simple input of requirements, offering high convenience and efficiency and greatly improving product quality.

It mainly checks caps for missing top logos and wrong-colour patterns to identify abnormal caps. Constructed from grade 304 stainless steel, it complies with hygienic production standards.
The cap-top logo inspection unit consists of one colour industrial camera and a ring-shaped LED light source, which identifies faulty caps based on pattern and colour differences. Besides, it judges cap damage via roundness measurement, adding an extra safeguard for cap inspection.
Inspects the resence of metal filling needles and other metal contaminants in bottle bottoms.
Implemented using high-sensitivity metal inspectors installed on both sides of the conveyor belt. Integrated with flexible rejection systems to uniformly collect and process defective.
