Carton coding 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
This system is designed for the online inspection of carton coding quality on beverage carton production lines. It automatically identifies and rejects defective cartons to ensure product traceability and compliance.
2. Key Features
Non-contact inspection method that operates online without causing damage to cartons.
High detection efficiency, capable of inspecting up to 60 cartons per minute.
User-friendly human-machine interface (HMI) with multiple access levels to ensure secure operation.
Customizable functions tailored to actual production site requirements.
Automatic daily storage of defective carton images, with adjustable retention period.
24/7 remote support services.
Continuous defective carton rejection during production line downtime.
II. Detection Capabilities
The system can detect the following defects in carton inkjet printing:
Missing printing – complete absence of inkjet code.
Blurred printing – characters unclear or indistinguishable to the human eye due to inkjet malfunction.
Character omission – more than 30% of a single character is missing.
Positional deviation – printed code falls outside the defined tolerance range.
Printing deformation – distorted results such as curved, elongated, or shortened codes.
Incorrect printing – wrong information such as date, factory code, or security code.
III. Installation Requirements
The equipment should be installed on a straight conveyor section of 1.5–2 meters, located immediately downstream of the inkjet printer, to ensure optimal detection performance.
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.
