1.Non contact online Inspection, no damage to the product.
2.The Inspection speed is fast, reaching up to 100 boxes per minute at the fastest.
3.Equipped with Al self-learning function to ensure the reliabilty of Inspection
I. Equipment Introduction
Application
Designed for online inspection of coding quality on beverage carton production lines, the system automatically identifies and rejects defective cartons to ensure consistent product quality.
Key Features
Non-contact inspection performed in real time, ensuring zero damage to products.
High-speed detection capability, supporting up to 60 cartons per minute.
User-friendly human-machine interface with configurable multi-level access.
Functions can be tailored to meet specific production site requirements.
Automatic storage of daily defect images, with customizable retention periods.
24/7 remote monitoring and service support.
Continuous rejection function with automatic downtime handling.
II. Detection Capabilities
Inkjet presence detection (identifies missing codes).
Blurred printing (unclear or illegible characters caused by printing issues).
Character omission (any character missing by more than 30%).
Position deviation (printing outside of the preset area).
Printing deformation (distorted, stretched, shortened, or curved codes).
Incorrect content (wrong date, plant code, or security code).
III. Installation Requirements
Installation location: 1.5–2 meters straight behind the inkjet printer on the production line.

4. Detection principle
A Gigabit digital camera is used to take pictures from top to bottom/side to collect pictures of the carton coding. The pictures are digitally analyzed and the cartons with unqualified coding are automatically and accurately removed online.
When a box passes the positioning sensor, its arrival is detected and the control unit records the box identification number and the current encoder signal. The positioning sensor triggers a digital camera to capture an image of the current box's coding and transmits it to the image processor via the network. The image processor processes and analyzes the received image and transmits the results to the human-machine interface for dynamic display and to the control unit. Upon receiving the unqualified coding signal, the control unit notifies the rejector to remove any boxes with unqualified coding corresponding to the identification number online.

E.Detection accuracy:
serial number
| Inspection Items | Detection Conditions and Accuracy | Rejection rate
| False kick rate
|
1 | Inkjet Printing Inspection | -- | -- | < = 0.03% |
1.1 | No inkjet printing | -- | >99.99% | |
1.2 | Missing inkjet printing | Single character > 30% | >99.8% | |
1.3 | Fuzzy inkjet printing | Indecipherable characters to the human eye | >99.93% | |
1.4 | Incorrect inkjet printing | Incorrect production date, incorrect factory code, incorrect security code, deformation (elongation or shortening) | >99.99% | |
1.5 | Position deviation | Exceeding the expansion zone | >99.99% | |
1.6 | Duplicate inkjet printing | Multiple codes printed within the code area | >99.99% |
Note: The rejection rate of the test item "no coding" described in the table means that out of 10,000 bottles of unqualified products without coding, there may be 1 box that is not rejected after being tested by the equipment. This is only theoretical experimental data, and the same applies to other test items.
