The work aims to develop an ultra high-speed rotary labeling machine that possesses high qualification rate and reliability. According to the basic theory of mechanical dynamics, some key technologies were improved, including label location mode, label pressing mode, missed label detecting and removing. The test results showed that the running speed of prototype reached 60,000 bottles/h and the labeling qualification rate was 99.5%. The prototype had realized the positioning labeling of double labels and three labels on the PET bottle in a mechanical method, which improved the precision of positioning labeling, reduced the machine cost, and avoided the instability of the photoelectric positioning. Besides, the prototype had more reliable automatic label removing function, which had solved the difficulty that the removing time was insufficient on the high-speed assembly line actuators. Furthermore, the prototype realized the function that the label could be pressed on the angular face between the PET bottle cap and bottle body, which improved the labeling effect and avoided the tilted label. The prototype achieves all the design indexes.
