To ensure accurate labeling, it is essential to adjust the position of the object-measuring electric eye and the marking eye. The object-measuring electric eye's position is crucial as it determines the timing of label issuance. Depending on the bottle's size, different positions are necessary. The electric eye's late position may result in premature label pasting or none at all, while a forward position can cause skewed or late labeling.
Similarly, the marking eye's position determines the label's positioning and length. A high measuring electric eye position can result in inadequate pre-labeling, leading to inaccurate labeling or backward pasting. In contrast, a low position can cause excess pre-marking, causing label wrinkles or forward labeling. Therefore, adjusting the measuring electric eye and target measuring electric eye is vital to ensure precise labeling, preventing labeling errors and improving production efficiency.
