Swing Wheel Sorter

1. Core Structure and Operating Principle

The Swing Wheel Sorter consists of a modular system including swing wheel units, conveying mechanisms, a drive system, a control system, and safety protection devices. Its core operation is based on independently controlled swing wheel modules, which adjust angle and speed dynamically to achieve precise sorting and routing of goods.

Swing Wheel Unit Design

Each swing wheel module adopts a tapered roller structure with a polyurethane-coated surface, providing:

• High wear resistance

• Anti-slip performance

• Shock absorption capability

This significantly reduces impact during sorting and protects goods from damage.

Each wheel unit is independently driven by a servo motor, capable of adjusting within a 0–90° range, enabling flexible directional diversion.

Conveyor Coordination

The conveying system works in coordination with swing wheel modules to ensure smooth material flow into the sorting zone. Dynamic torque distribution ensures stable handling of both light and heavy parcels without jamming or deviation.

Control System

The system adopts a PLC + HMI touchscreen architecture, supporting:

• Manual mode

• Semi-automatic mode

• Fully automatic mode

Advanced configurations may include:

• Laser vision recognition

• AI-based sorting algorithms

These systems can complete parcel identification (size, weight, destination) within 0.3 seconds, optimizing sorting paths in real time.

It supports integration with WMS, WCS, and TMS systems, enabling intelligent dispatching, data traceability, and full-process automation.

2. Key Performance Advantages

1. High efficiency and wide adaptability

The Swing Wheel Sorter typically achieves:

• 3,000–5,000 parcels/hour (standard models)

• Supports loads up to 80 kg per item

It can handle:

• Small parcels (0.1 kg)

• Large cartons up to 1.5 meters in length

• Irregular and soft packages

This eliminates the need for equipment changeover when handling mixed product flows.

2. Gentle handling with low damage rate

Thanks to polyurethane-coated wheels and adaptive pressure control, the system minimizes impact forces during sorting.

In fragile product applications (e.g., glass bottles), damage rates can be reduced from 1.5% to below 0.03%, significantly improving product safety.

3. Strong system integration and scalability

The modular design allows:

• Flexible expansion in length and width

• Easy integration into existing conveyor systems

• Compatibility with high/low temperature and dusty environments

It supports industrial communication protocols such as:

• Profinet

• EtherCAT

It can be seamlessly connected with AGVs, conveyors, and automated packaging machines.

4. High reliability and easy maintenance

The system features:

• Simple mechanical structure

• Low failure rate

• 24/7 continuous operation capability

Maintenance mainly includes:

• Wheel surface cleaning

• Motor and cable inspection

• Lubrication replenishment

Some advanced models include PHM predictive maintenance systems, capable of forecasting failures up to 72 hours in advance.

3. Industry Applications

1. E-commerce and express logistics

Widely used in parcel distribution centers for high-speed sorting of mixed parcels. Integrated with WMS systems, it significantly improves order fulfillment efficiency and reduces labor costs by over 65%.

2. Home appliance and automotive parts industry

Suitable for heavy and irregular goods such as:

• Large appliance cartons

• Automotive components

It improves sorting efficiency by up to 300% compared to manual operations, ensuring stable and continuous flow handling.

3. Food and pharmaceutical industry

Designed for hygienic environments:

• Food-grade polyurethane wheels

• Cleanroom-compatible structure

It supports temperature-controlled environments from -20°C to 45°C, ensuring cold chain integrity and compliance with industry regulations.

4. Cross-border cold chain logistics

Operates reliably in -18°C environments, handling high-value frozen goods such as seafood and imported beverages. It reduces manual exposure to low temperatures and improves cold chain efficiency.

4. Selection and Maintenance Guidelines

Key selection factors

1. Load and size

• Define parcel weight and dimensions

• Ensure sufficient load margin

• Heavy-duty systems support up to 80 kg per item or more

2. Speed and precision

• Select based on required throughput

• Vision-based systems recommended for high-precision sorting

3. Environment compatibility

• Temperature, humidity, and dust resistance

• Ensure proper protection rating and system compatibility

Daily maintenance

• Daily: clean wheels and conveyor surface

• Weekly: inspect servo motors, sensors, and safety systems

• Every 3–6 months: replace lubricants, calibrate system, and check electrical components

5. Development Trends
