Visual Inspection System For Cigarette Tobacco Leaves Surface Checking

System description

Inspection principle

Visual inspection systems have been widely used in many industries. CCD industrial cameras are used to capture the detected images, and then converted into digital information. By processing and judging the image digital signals, the on-site equipment actions are controlled.

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

Inspection details

1. Packaging appearance quality inspection

Extract the cigarette pack image and convert it into digital image information, send it to a dedicated image processing system, perform various operations on these signals according to pixel distribution, brightness, color and other information to extract the characteristics of the target, and then control the culling action according to the results. . Realize comprehensive quality monitoring of cigarette packs on high-speed running machines, effectively avoid mislabeling, warped edges, whitening, bottom edge opening, reverse packs, damage, deformation, etc.

2. Inspection of the appearance of cigarettes

The high-speed cigarette machine has a very fast production speed, and the cigarette detection system is an indispensable packaging quality control component in the cigarette packaging machine.

3. Identification of anti-counterfeiting code

Coding technology refers to the printing of serial numbers, expiration dates, batch numbers, logos, brand names and other information on various packages of smoking products, and is widely used in the manufacture of smoking products. The detection of the anti-counterfeiting code mainly focuses on the detection of the anti-counterfeiting code of the transparent outer wrapping paper of the small package.

4. Sealing misplacement and deletion detection

The top seal of soft-pack cigarettes is used as a sign of the relevant information of cigarettes. In the process of cigarette packaging, it should be ensured that the position of the seal is correct and cannot be missing. A detection device is needed to monitor in real time to ensure that each box is The quality of the cigarette's seal. The machine vision technology has the advantages of simple setting, powerful image grayscale analysis function, and large grayscale recognition range, which can realize the identification of the seals of cigarettes from different manufacturers, and improve the stability of the packaging machine.

The application of machine vision technology and the packaging of tobacco products can ensure the smooth progress of high-speed, automated cigarette pack production. At the same time, the detection data of the vision system can help the management department to find potential problems in equipment and materials in time, which is conducive to improving the overall management level of cigarette enterprises.
