1. Core Structure and Working Principle

The equipment consists of six core modules: roller conveyor unit, merging guide mechanism, drive module, sensing detection unit, electrical control system, and frame structure. The overall structure is compact, easy to install, and suitable for straight-line and curved production layouts. It can be flexibly adjusted according to the number of branch lines and material specifications without major modifications to existing production lines, effectively solving common issues such as improper layout and speed mismatch in traditional merging systems.

1. Roller Conveyor Unit

As the core load-bearing and conveying component, it consists of evenly arranged driven and idler rollers. Roller materials can be selected based on application requirements, including:

• Carbon steel galvanized rollers

• Stainless steel rollers

• PU-coated rollers

Common roller diameters: Φ38 / Φ42 / Φ50 / Φ60 / Φ70 mm
Length can be customized according to material size
Standard roller pitch: 75 / 100 / 125 mm

The design ensures that each conveyed item is supported by at least three rollers during transport, ensuring stable conveying and preventing tilting or deviation during merging.

Both ends of the rollers use precision ball bearings and sealed end caps, providing low rotational resistance and excellent dust- and water-proof performance. The system can operate stably in environments ranging from 0°C to +40°C, reducing failures and extending service life.

2. Merging Guide Mechanism

This is the key execution component designed for material convergence. It consists of:

• Merging guide plates

• Adjustable deflection plates

• Synchronized conveying components

The guide angle is adjustable from 0° to 90°, allowing compatibility with various branch-to-main line layouts.

Key features:

• Guide plates are made of wear-resistant and anti-slip materials, ensuring smooth material turning without collision or scratching

• Adjustable guide plates accommodate different material sizes for precise alignment

• Synchronized conveying components coordinate branch and main line speeds to prevent congestion caused by speed mismatch

This ensures orderly and efficient merging and fundamentally eliminates flow imbalance at merging points.

3. Drive Module

The system uses either motorized rollers or geared motor drives. The preferred solution is an integrated motorized roller, where the motor and gearbox are built inside the roller, offering:

• Compact structure

• High transmission efficiency

• Low noise

• No external drive frame required

Power range: AC 90W / DC 10–150W
Speed range: 0–100 m/min stepless speed control

The system can adjust speed according to merging rhythm and material characteristics, ensuring smooth synchronization between branch and main lines.

Cooling options include:

• Oil-cooled

• Oil-immersed

• Air-cooled

It offers excellent sealing performance and can operate reliably in dusty or humid environments.

4. Sensing and Electrical Control System

The sensing system includes photoelectric sensors and proximity switches installed at branch exits, merging zones, and main line inlets. It collects real-time data such as position, speed, and quantity of materials, ensuring accurate triggering of merging actions.

The control system uses PLC-based logic control with a touchscreen interface, supporting:

• Manual mode

• Automatic mode

• Linked operation mode

It supports preset merging logic, speed control, and timing coordination, and is compatible with major industrial communication protocols such as Profinet and Modbus.

It can integrate seamlessly with existing production systems, including AGVs, sorting machines, and barcode scanning systems, enabling fully automated merging operations and coordinated multi-branch material flow.

5. Frame Structure

The frame is constructed from carbon steel, aluminum profiles, or stainless steel. Surface treatments include spraying, anodizing, or polishing, providing:

• Corrosion resistance

• Structural stability

• Anti-deformation capability

The frame height is adjustable to match different conveyor elevations and production layouts. Side guards and protective rails can be added to prevent material deviation or falling during transport.

The modular design allows flexible expansion, making it suitable for different numbers of branch lines and varying system lengths, supporting future capacity upgrades without replacing the entire system.

6. Working Principle

Materials from each branch line are transported via roller conveyors into the merging zone. Sensors detect position and speed signals and transmit them to the control system.

Based on pre-set logic, the system:

• Controls guide mechanism movement

• Synchronizes branch and main line speeds

• Ensures orderly material entry into the merging channel

Guide plates and deflection components direct materials smoothly into the main conveyor line, preventing collision, congestion, or blockage.

The entire process is fully automated, continuous, and requires no manual intervention, making it suitable for high-frequency, large-volume merging operations.

2. Core Performance Advantages

1. Precise and Smooth Merging

Real-time coordination of speed and position ensures accurate merging with minimal collision or blockage.

2. Compact Structure and High Flexibility

Modular design supports 2–6 branch lines and can be customized for different layouts and material types without major production line modifications.

3. Stable Operation, Low Noise, Energy Efficient

Standardized components ensure low failure rates and 24/7 continuous operation. Energy-efficient motorized rollers reduce power consumption, while operating noise remains ≤65 dB.

4. Wide Applicability and Strong Compatibility

Handles materials from 5–50 kg, including cartons, totes, trays, electronic parts, food packaging, and automotive components. Easily integrates with existing conveyor, sorting, and automation systems.

5. Easy Maintenance and Long Service Life

All components are standardized for easy replacement. Daily maintenance is simple and requires no specialized technicians. Sealed rollers reduce dust and moisture intrusion, extending service life.

6. High Safety and Environmental Adaptability

Equipped with emergency stops, overload protection, and safety guards. Protection rating reaches IP54 or higher, with optional IP67 for harsh environments such as dust, humidity, and cleanroom conditions.

3. Typical Industry Applications

1. E-commerce Logistics and Express Warehousing

Used for multi-branch merging of parcels and cartons into main lines, improving sorting efficiency during peak seasons and enabling automated classification via scanning systems.

2. Food and Pharmaceutical Industry

Uses stainless steel frames and food-grade components, ensuring hygienic operation. Suitable for packaging, pharmaceutical boxes, and cleanroom environments with strict hygiene requirements.

3. Electronics and Home Appliance Manufacturing

Supports multi-branch merging of electronic components and appliance parts into assembly or packaging lines. Low noise and precise control improve production efficiency.
