Inspection of capping defects in the process of beverage filling

a long time ago, the beverage industry began to use various inspection instruments. In recent years, with technological progress, Detection equipment has developed from simple sensors to complex imaging systems in the cooperation of HP; from early pure detection equipment, such as checking whether boxes and bottles exist, it has further developed into liquid level detection, empty box and empty bottle detection. <(2) Although the zigzag test position of the oil cylinder down type universal testing machine is relatively low/p>

in addition to the above characteristic indexes, there are some other factors, such as appearance. It is an important link that affects consumers' buying motivation in China, which is still in the stage of industrialization, informatization, urbanization, marketization and internationalization. It also requires strict final inspection. Especially for high priced products. If the appearance quality is inconsistent with the internal quality of the product, the brand value will soon be lost

in the production process, we found that if the position behind the capping machine is adjusted improperly, various defects will appear. For example, the type of bottle cap also determines the form of defect. If the crown cap is used, the defect of the bottle cap is generally identified by the amount of pressure measurement in the gap of the market segment. When testing plastic covers, the effect of optical detection system is better. The quality of the closure can be determined by measuring the position of the bottle cap and the safety ring. Aluminum screw covers have more types of defects (as shown in the figure below)

after the complex rolling process, the possible defects may not affect the sealing at that time, but with the passage of time, this kind of bottle cap will appear the phenomenon of loose sealing, resulting in the early deterioration of the product. In addition, when opening these bottle caps, consumers may be injured. Only when the bottle cap enters the capping machine correctly, the whole capping process is adjusted accurately, and the raw materials of the bottle cap and the container meet the requirements, can the normal capping process be realized

the typical deviation of each link in the capping process leads to typical defects, which are mainly manifested as follows: partial capping, the so-called sleeping cap; Cover rolling is light; The breaking point of each section is disconnected in advance; Some safety rings are not compressed, and some areas are cocked up; The safety ring is not compressed at all, etc

the safety ring breaks and the eccentric cap (nightcap) breaks in advance

at present, through rolling inspection, the defects of the bottle cap and capping machine can be determined by the following description: through the statistical distribution between the bottle cap defects determined by the "capping machine detector" and each workstation of the capping machine, the causes of the defects can be effectively identified, so as to purposefully repair the capping workbench that has problems. This can save time and reduce costs. It can not only improve the overall quality of the cover by using this kind of detection, but also improve the efficiency of the whole filling line
