In recent years, with the advancement of technology, the Braun test equipment has evolved from a simple sensor to a complex imaging system; from the early pure inspection equipment, such as the inspection of the existence of boxes and bottles, it has further developed into liquid level detection, empty boxes and Empty bottle inspection.
In addition to the above characteristics, there are other factors, such as appearance. It is an important part of the motivation of consumers to buy, also requires a strict end of the test. Especially for high-priced products. If the quality of the appearance does not match the intrinsic quality of the product, the brand value will soon be lost.
During the production process, we found that if the position after the capping machine was improperly adjusted, various defects will occur. For example, the type of cap also determines the form of the defect. If a crown cap is used, the pressure measurement is generally used to identify the cap defect. The optical inspection system works better when the plastic cover is tested. The quality of the closure can be determined by measuring the position of the cap and safety ring. The aluminum screw cap has more types of defects (see the figure below).
After a complicated rolling process, the defects that may occur may not affect the seal at that time, but over time, the cap may be tightly sealed, resulting in deterioration of the product in advance. In addition, when these caps are opened, it is possible to cause harm to the consumer. The normal closure process can only be achieved when the cap is properly inserted into the capper, the entire capping process is precisely adjusted, and the material of the cap blank and the container are guaranteed to meet the requirements.
The typical deviation of each link in the process of capping leads to typical defects. The main performances are: partial cover, the so-called nightcap; the cover is lightly rolled; the break points of each section are disconnected in advance; some of the safety rings are not compressed. Some areas are lifted; the safety ring is not pressed at all, and so on.
