In AGV automated handling processes, the conveyance mechanism acts as the “logistics hand,” enabling seamless transfer of goods between AGVs, production lines, and racks. Roller, belt, and chain—the three mainstream transfer systems—each offer distinct advantages. Their selection directly impacts handling efficiency and system compatibility. This guide analyzes core characteristics and selection logic to optimize logistics operations.

Conveyance Mechanism: The “Dynamic Interface” for AGV Transfer

As the physical interaction point between AGVs and external environments, conveyance mechanisms must fulfill three core functions:

1.Precise Positioning: Align with target stations within ≤±5mm error for smooth cargo transfer.

2.Efficient Transfer: Complete cargo handover in 3–15 seconds (size/weight-dependent).

3.Adaptive Compatibility: Handle diverse cargo types (cartons, pallets, irregular items).

Typical Challenge: An electronics factory suffered PCB misalignment due to belt slippage, causing 8 failed transfers per hour.

Core Technology Comparison of Three Conveyance Systems

1.Roller Conveyor: The Epitome of Rigidity & Efficiency

Structure:

Parallel alloy steel rollers (Ø50–120mm) with polyurethane anti-slip coating.

Motorized drum or external drive (torque ≥200N·m for 1.5-ton pallets).

Advantages:

High load capacity: Static 3 tons, dynamic 1.5 tons.

Ideal for standardized pallets (EU/JIS standards), transfer speed 0.3–0.8m/s.

40% lower maintenance cost than chains.

Best For: Palletized logistics (auto parts, chemical raw materials).

2.Belt Conveyor: Master of Flexible Handling

Design Innovations:

Anti-static PVC/PU seamless belts (3–8mm thickness) with non-slip textures.

Variable-frequency drive with ±0.05m/s speed accuracy.

Unique Value:

Vibration-free transfer: Protects fragile items (glass, instruments).

Handles non-palletized loads (soft packages, cartons, bins).

Incline capability (≤15°) for multi-floor transport.

Typical Use: Carton automation in electronics/medical warehouses.

3.Chain Conveyor: Fortress of Heavy-Duty Durability

Breakthroughs:

Dual-strand roller chains (ISO 606), breaking strength ≥30kN.

Sealed lubrication (IP65-rated) for dust/corrosion resistance.

Performance Limits:

Extreme loads: Dynamic 5 tons, static 8 tons (exceeding rollers/belts).

Withstands 120°C heat/oily environments (e.g., auto paint shops).

50,000+ hour lifespan (3× longer than belts).

Primary Domain: Heavy machinery, metal raw material handling.

Selection Decision Tree: 4 Dimensions to Optimize Choice

Based on 200+ AGV projects, we refined this selection logic:

Advanced Considerations:

Power: 48V DC motor (roller/belt) vs. 380V AC motor (chain).

Control: CANopen/EtherCAT support for speed-position sync.

Safety: E-stop interlock, anti-pinch guards, overload sensors.

Maintenance: Belt replacement (2 years), chain lubrication (6-month intervals).

Collaborative Innovation: Transforming Conveyance into a Competitive Edge

Conveyance mechanisms thrive on synergy between mechanical design, electrical response, and environmental adaptation. As an AGV core component partner, we deliver:

Scenario-Driven Customization:

For electronics: Magnetic navigation + belt alignment (≤1mm error).

For heavy industry: Hydraulic lift + dual-chain platforms (8-ton stable operation).

End-to-End Support:

Structural stress simulations to predict roller/chain fatigue.

Control protocol integration guides (1-hour compatibility with AGV controllers).

Lifecycle Management:

Quick-release modules (belt/roller swap ≤30 minutes).

Remote diagnostics for real-time motor temperature/load monitoring.
