Share the application of machine vision inspection system in cigarette product packaging inspection

With the rapid development of automation, machine vision inspection systems are widely used in many industries with the advantages of high speed, high efficiency, and non-contact. Among them, the main applications in the packaging of tobacco products are as follows:

1. Packaging appearance quality inspection

The cigarette pack image is extracted and converted into digital image information, which is transmitted to a dedicated image processing system, and the characteristics of the target are extracted by various calculations based on the pixel distribution, brightness, color, and other information, and the rejection action is controlled according to the result. Realize comprehensive quality monitoring of cigarette packs on high-speed running machines, and effectively avoid wrong cards, warping, revealing white, bottom edge glue, reverse packing, damage, deformation, etc.

2. Detection of cigarette shape

The production speed of high-speed cigarette machine is very fast, and the cigarette detection system is an indispensable packaging quality control component in the cigarette packaging machine, which detects the lack of cigarette packaging, lack of mouth, empty head, reverse branch, etc., to ensure the quality of cigarettes.

3. Identification of anti-counterfeiting code

Inkjet coding technology refers to printing various information such as number, expiration date, batch number, logo, brand name and other information on various packages of tobacco products, which is widely used in the manufacture of tobacco products. The detection of anti-counterfeiting code is mainly focused on the detection of anti-counterfeiting code of small packaging, transparent outer wrapping paper, and anti-counterfeiting code detection of boxes and cigarettes.

4. Seal misplacement and missing detection

In the process of cigarette packaging, it should be ensured that the position of the seal is correct and cannot be missing, and a detection device is needed to monitor it in real time to ensure the quality of the seal of each box of cigarettes. The machine vision technology has the advantages of simple setting, powerful image grayscale analysis and large range of grayscale recognition, which can realize the seal recognition of cigarettes from different manufacturers and improve the stability of the packaging machine.
