In the application of labeling machines, different scenarios have distinct requirements. To address these needs, we have developed corresponding solutions to ensure accurate and efficient labeling operations.

Scenario Requirement 1: Label Position Detection for Precise Labeling

Heyi Solution: Accurate detection of label position is the foundation for precise labeling during the labeling process. Deviations in label positioning will directly lead to skewed labels, compromising product appearance.

To meet this requirement, we adopt the photoelectric label sensor LA-B12 for label detection and positioning.

Technical Advantages

✅ High detection accuracy: Based on the photoelectric detection principle, it can accurately detect opaque labels.

✅ High-speed switching frequency: Fast response speed; metal housing ensures sturdiness and durability.

✅ Long slot design: Facilitates label placement and detection.

✅ Easy adjustment: Calibration value display and error warnings for functional operations can be easily adjusted via the enclosed calibration button or calibration output.

✅ Adaptive logic circuit function (Auto Level Control, ALC): Achieves optimal performance by independently optimizing the switching threshold.

Scenario Requirement 2: Bottle Positioning Before Labeling (for Specific Labeling Machines)

Heyi Solution: Some labeling machines require precise positioning of bottles before labeling. This is because bottles may vary in shape and size, or labels need to be applied to specific parts of the bottle (e.g., bottle neck, specific height of the bottle body). Inaccurate bottle positioning will result in labels being applied in non-compliant positions.

For this scenario, we mostly use the EB-C1 for bottle positioning prior to labeling.

Technical Advantages

✅ Accurate identification of subtle color differences: Capable of precisely recognizing over 1,000 types of colors.

✅ 4-channel design: Can store 4 colors simultaneously and output single-channel signals in sequence.

✅ Strong probe compatibility: In addition to dedicated color probes, it is compatible with all types of fiber optic probes, ensuring higher detection adaptability.

✅ Multiple detection modes: Suitable for various application scenarios.

Scenario Requirement 3: Detect Incoming Materials → Clamp → Rotate for Labeling

Heyi Solution: When incoming materials enter the working area of the labeling machine, they need to be detected first, then clamped and fixed, and labeling is completed through rotation. This scenario is common for cylindrical products or products requiring multi-sided labeling.

To address this requirement, we adopt the combined solution of FM-E31 + FN-D076.

Technical Advantages

FM-E31

✅ One-button setup: Completes configuration with just one key press.

✅ High power: Reduces manual adjustment time.

✅ Flexible application modes: 4 modes to choose from.

✅ Versatile signal options: Switch signal/analog signal selection; single signal/dual signal selection; NPN/PNP signal output selection; normally open/normally closed interchangeability.

✅ Powerful function combination, high stability, and comprehensive circuit protection.

FN-D076

✅ Minimum bending radius of R25.

✅ Temperature resistance: -40°C to +70°C and above.

The above solutions select appropriate sensors based on the needs of different labeling scenarios, effectively ensuring the quality and efficiency of labeling operations and providing reliable support for the labeling process of various products.
