Express Sorting Systems: Practical Tools for Modern Logistics

Common Types of Sorting Equipment

1. Cross-Belt Sorters

It is widely used for sorting large volumes of parcels, especially in express delivery transfer centres.

- Capable of sorting up to **30,000 parcels per hour.
- Suitable for small and medium-sized parcels weighing **0.1–10 kg.
- Low error rate, continuous operation
- Requires stable layout and consistent flow

2. Shoe Sorters

- Designed for items that require gentle handling.
- Suitable for:
- Clothing, electronics, fragile goods
- Low-noise environments
- Energy-efficient operations
- Facilities with moderate throughput

3. Wheel Sorters

Simple and reliable for standard packages.

Advantages:

- Easy to install and maintain
- Good for boxed items
- Lower upfront cost
- Compact footprint

4. Robotic Sorters

Flexible systems for mixed or irregular items.

Features:

- Vision-based identification
- Adjustable to different shapes and sizes
- Can learn and improve performance over time
- Useful where standard sorters are not practical

 Why Use Automated Sorting?

Higher Throughput

- Processes more packages with fewer people
- Reduces manual handling
- Helps manage peak periods

Lower Costs

- Cuts labor and training expenses
- Minimizes sorting mistakes and returns
- Improves use of warehouse space

Consistent Accuracy

- Error rates much lower than manual methods
- Each package is tracked and recorded
- System can flag issues early

Key Functions

Measurement and Tracking

- Automatic weighing and dimensioning
- Real-time data logging
- Integrated with billing or inventory systems

Routing and Control

- Sorts by destination, carrier, or priority
- Adapts to changing conditions
- Flags and redirects problem parcels

Quality Checks

- Detects damaged packaging
- Confirms labels are scannable
- Logs issues for review

Load Balancing

- Buffers high-volume input
- Coordinates with upstream and downstream systems
- Helps prevent overloads and congestion

Planning Considerations

Before installing a sorting system, review the following:

- Volume: How many parcels you handle daily and during peak seasons
- Space: Available floor area, ceiling height, and layout constraints
- System Integration: Compatibility with existing software and hardware
- Budget: Total cost, maintenance needs, and expected return
