Outer Box Coding Visual Inspection Machine
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
Equipment Overview
Application
This system is designed for real-time online inspection of printing quality on beverage carton production lines. It automatically detects and removes defective cartons to ensure consistent quality across all products.
Key Features
Non-contact inspection: Ensures products remain intact during inspection
High throughput: Capable of inspecting up to 60 cartons per minute
User-friendly HMI: Supports multiple levels of access for secure operation
Customizable functions: Adjustable to meet the specific requirements of different production lines
Automatic defect image storage: Defective carton images are saved with configurable retention periods
24/7 remote support: Ensures continuous technical assistance
Continuous rejection mode: Prevents defective cartons from passing even during line stoppages
Detection Capabilities
The system can detect a wide range of printing issues, including:
Missing inkjet codes
Blurred or unclear characters due to poor print quality
Incomplete characters (loss exceeding 30%)
Misaligned printing (beyond the specified tolerance range)
Distorted codes (curved, stretched, or shortened)
Incorrect information (e.g., wrong date, factory code, or security code)
Installation Requirements
For optimal performance, install the system 1.5–2 meters downstream from the inkjet printer, on a straight section of the conveyor.
Detection Principle
The system uses a Gigabit digital camera to capture top-down or side-view images of the carton codes. These images are analyzed digitally, and cartons with unqualified codes are automatically removed from the production line.
Operation workflow:
1. As a carton passes the positioning sensor, the system records its ID and the current encoder signal.
2. The sensor triggers the camera to capture an image of the carton’s code, which is sent to the image processor.
3. The processor analyzes the image and sends results to both the human-machine interface for real-time display and the control unit.
4. If a defect is detected, the control unit instructs the rejector to remove the corresponding carton from the line automatically.

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.
