Application of machine vision inspection system in removing tobacco debris defects

  Since the entire process of tobacco leaves from entering the production line of the cigarette factory to producing finished cigarettes has gradually been separated from manual assistance, especially after the leaves are changed into single leaves, there is no longer a manual leaf laying process, so the impurities mixed in the tobacco leaves Objects and moldy tobacco leaves cannot be removed. They have a greater impact on the quality of cigarette products. Tobacco debris removal equipment is a system that removes debris and moldy tobacco leaves in the initial processing of tobacco leaves, threshing, roasting, leaf shreds and stem shreds on the shred production line.

Application of machine vision inspection system in removing tobacco debris defects:

1. Material single-layer processing device: Its function is to change materials such as tobacco leaves from a thick layered state into a thin single-layer state, and use "pressure air" and "support air" to make the tobacco leaves pass smoothly from the output end of the belt conveyor It is thrown to the ground and runs stably along a predictable flat motion trajectory, providing conditions for subsequent visual inspection.
2. Material lighting system: Its function is to provide lighting for materials. To obtain high-quality image signals, sufficient illumination of the material is one of the most important prerequisites.
3. Optical system: Its function is to send the reflected light from the surface of the material to the photoelectric detection element (such as CCD photosensitive element) as accurately as possible.
4. Material image acquisition system: Its function is to use the EM510 camera to obtain the image (reflected light on the surface of the material) information of the material, and perform A/D conversion through the image acquisition card to convert the analog image signal into a digital signal that the computer can accept and process. image signal.
5. Real-time image processing system: Its function is to perform necessary operations and processing on the collected digital image signals, extract characteristic parameters, and output the judgment results according to the preset judgment criteria through the intelligent judgment and decision-making module, and generate a Control instructions for the actuator. It includes computer hardware (such as DSP or specialized image processing card) and software.
6. Debris removal system: Its function is to separate debris from the tobacco leaf flow. Compressed air injection is used in this system. It includes a high-speed pneumatic solenoid valve group and a blowing cavity.
The application of comprehensive machine vision technology will be increasingly used in quality inspection, monitoring and sorting in the tobacco industry with the full implementation of quality improvement and consumption reduction projects in the tobacco industry.
