I. Equipment Overview
1. Application Scope
This system is designed for online inspection of carton coding quality on beverage carton production lines. It automatically detects defective coding and removes faulty cartons from the line.
2. Key Features
Non-contact online inspection, ensuring products remain undamaged.
High-speed detection, capable of inspecting up to 60 cartons per minute.
User-friendly HMI, with multi-level user permissions for secure access.
Flexible configuration, adaptable to specific on-site production requirements.
Automatic defect image storage, with adjustable storage duration to meet user needs.
24/7 remote technical support for continuous operation assurance.
Automatic rejection during machine downtime, preventing defective cartons from passing.
II. Inspection Capabilities
The system provides comprehensive coding quality checks, including:
Code presence detection – identifies missing inkjet prints.
Blur detection – detects blurred characters that are hard to read.
Character omission – flags missing characters where over 30% of a single character is absent.
Position accuracy – detects codes outside the preset alignment range.
Code distortion – identifies bent, elongated, or shortened prints.
Content validation – checks for incorrect codes such as wrong dates, factory codes, or security codes.
III. Installation Requirements
The inspection unit should be installed 1.5–2 meters downstream from the inkjet printer on a straight section of the conveyor to ensure stable and accurate detection.
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.
