With the improvement of people's living standards, people have higher requirements for the appearance and packaging of consumer goods. For example, whether the trademarks of some famous wines and high-end wines are beautiful and pleasing to the eye, which plays an important role in the classification of alcoholic beverages. For another example, the relatively strict requirements for the position of the trademark on the container have resulted in a fully automatic labeling machine. The following analyzes several factors that affect the failure of the labeling machine:

1. From the perspective of the entire operation process of labeling, including: taking label, sending label, while container transport, positioning, then labeling, labeling, and rolling. From the perspective of the process route of the labeling machine, the factors that affect the labeling accuracy include: container positioning accuracy, labeling accuracy, labeling accuracy, and label rubbing accuracy.

2. Accurate positioning of the container. When the position of the meter label on the bottle has strict requirements, strict positioning is required.

Common positioning methods mainly use the shape of the container, such as the concave point on the container, the mold line, the photoelectric positioning point, etc., and the servo mechanism is usually equipped to feedback and adjust the position of the container.

3. Labeling accuracy: When labeling, there is a deviation when the bottle rotates and the label moves. This deviation is a fatal blow to the labeling accuracy. Therefore, it is necessary to design a synchronization mechanism. At the moment of labeling, the bottle rotation linear speed and the label extension speed are equal to achieve relative static and improve labeling accuracy.

4. Accuracy of labeling and rubbing. The label to be applied needs labeling and rubbing device to make it closely adhere to the bottle, but at the moment of contact, the label and the bottle are easy to slide, which affects the accuracy. Therefore, the design of overriding and rubbing must be reasonable.
