Carton Visual Inkjet 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
I. Equipment Overview
1. Application Scope
This system is designed for online inspection of carton code quality in beverage carton production lines. It automatically identifies and rejects defective cartons without disrupting production.
2. Key Features
Non-contact, real-time inspection with no risk of product damage.
High inspection capacity, supporting speeds of up to 60 cartons per minute.
User-friendly HMI with multi-level access control.
Customizable functions tailored to specific production line requirements.
Automatic storage of defective carton images with adjustable retention periods.
24/7 remote support services.
Continuous rejection capability during production downtime.
II. Inspection Capabilities
The system performs multiple checks to ensure code integrity, including:
Verification of inkjet presence (detection of missing codes).
Identification of blurred or illegible prints caused by faulty inkjet nozzles.
Detection of missing characters (greater than 30% of a character missing).
Monitoring of print position accuracy (flags deviations outside set tolerances).
Detection of distorted prints (curved, elongated, or shortened codes).
Verification of content accuracy (e.g., production date, factory code, security code).
III. Installation Requirements
For optimal performance, the system should be installed 1.5–2 meters directly downstream of the inkjet printer on the production line, ensuring a stable and straight conveyor path.
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.
