I. Comparison of Core Pagination Methods

1. Vacuum Suction Pagination

• Principle: Using vacuum suction cups to generate negative pressure, the top single product from stacked materials is adsorbed, precisely positioned by sensors, and then conveyed to the labeling station.

• Advantages:

• Non-contact operation prevents scratches on soft/thin materials (e.g., 0.05mm PE bags, aluminum foil bags).

• Auto-adjustable feed port for varying material thicknesses.

• Typical Parameters: Pagination accuracy ±0.1mm, speed 150-200pcs/min,适用产品厚度0.2-5mm。

2. Friction-Based Pagination

• Principle: Utilizes high-speed rotating friction wheels and mechanical force to separate materials, controlled by speed ratio adjustment.

• Advantages:

• Simple structure, lower cost.

• Suitable for rigid materials (e.g., cards, plastic boxes).

• Limitations: Prone to damaging ultra-thin/deformable products, accuracy ±1mm.

3. Pneumatic Pagination

• Principle: Employs pneumatic cylinders or air jets to separate materials, combined with vacuum suction for stable conveyance.

• Advantages:

• High-speed pagination, efficiency increased by 30%.

• Adaptable to greasy or curved packaging (e.g., food bags, glass bottles).

• Case Study: Fujian Licheng Sausage Production Line achieves over 100,000 units/day.

4. Mechanical Pagination

• Principle: Linked system of pagination wheels and belts, with frequency converters regulating speed to dynamically compensate for bottle variations.

• Advantages:

• Repeat positioning accuracy ±0.02mm, supports six-axis parallel labeling heads.

• Ideal for precision products (e.g., IC cards, chip labels).

II. Technical Breakthroughs and Industrial Applications

1. Vision Positioning System

• High-precision sensors identify product positions within 0.1 seconds, with error ≤±0.005mm, enabling label placement on 0.2mm-spaced electronic components.

• Application: Huabei Pharmaceutical’s vaccine bottle UDI code dynamic labeling.

2. Modular Design

• Labeling heads can be swapped in 5 minutes (pneumatic/electric), with rails adapting to 100-500mm strokes for multi-size compatibility.

• Application: Jinan Yihe Food’s glass jar dual-sided labeling.

3. Intelligent Control System

• Touchscreen integrates auto-bottling, production counting, and fault stoppage, with closed-loop feedback adjusting pagination roller gaps.

• Application: Sinovac’s irregular bottle labeling efficiency improved by 40%.

III. Selection Guide: Matching Production Needs

IV. Future Trends: Intelligence and Flexibility

• IoT Integration: Remote monitoring and predictive maintenance reduce downtime.

• AI Algorithm Optimization: Real-time analysis of label wrinkles/offsets, dynamic parameter adjustment.

• Eco-Friendly Material Adaptation: Develop biodegradable label pagination technology for green manufacturing.

       The choice of pagination method for automatic flat labeling machines depends on material properties, production efficiency, and accuracy requirements. Vacuum suction and pneumatic pagination excel in flexible packaging, while mechanical pagination with vision systems dominates precision manufacturing. With modular design and AI integration, equipment is evolving toward “multi-purpose” flexibility, offering efficient automation solutions for food, pharmaceutical, and electronics industries.Dawei Machinery recommends different pagination techniques to clients based on varying products to help address their specific needs.
