Automated sorting machines can be categorized into several types based on their operating methods and technologies, including traditional conveyor sorters, cross-belt sorters, sliding-shoe sorters, high-speed putwall sorters (flash pick), and 3D intelligent sorting systems.
-
Traditional Conveyor Sorting
-
How it works
- Uses roller or belt conveyors to move goods, with mechanical devices (e.g., diverters, blockers) directing items to different destinations.
-
Features
- Ideal for large volumes of standardized goods.
- Offers high stability and easy maintenance.
- Sorting paths are fixed, less flexible.
-
Applications
- Manufacturing, warehousing, and retail (e.g., beverages, daily goods).
- Traditional logistics centers, especially for long-distance transport.
-
-
Cross-Belt Sorter
-
How it works
- Items are placed on small cross-belts that independently move sideways to quickly sort items to different destinations.
-
Features
- High-speed and high-precision sorting (up to 10,000–20,000 items/hour).
- Ideal for small packages and high-frequency orders (e.g., e-commerce, express logistics).
- Supports a wide variety of packaging types (bags, boxes, envelopes).
-
Applications
- E-commerce and express logistics centers (e.g., Double 11, Black Friday sales).
- Air freight sorting for handling various parcel sizes.
-
-
Sliding-Shoe Sorter
-
How it works
- Uses sliding mechanisms or push plates to gently divert items from the main conveyor to designated chutes.
-
Features
- Gentle sorting, suitable for fragile goods.
- Handles various sizes and shapes of goods; high flexibility.
- Suitable for 3C electronics, food, and pharmaceutical industries.
-
Applications
- 3C electronics (smartphones, laptops, components).
- Packaged foods, chilled items.
-
-
High-Speed Putwall Sorter (Flash Pick)
-
How it works
- Combines high-speed picking and conveying, using robotic arms or airflows to quickly sort items.
-
Features
- Ideal for mass sorting of standardized goods like clothing, books, cosmetics.
- Perfect for large-scale promotions (e.g., Double 11, 618).
- Fully automated, minimal manual intervention.
-
Applications
- E-commerce warehouses (e.g., JD, Taobao, Amazon).
- Large-scale logistics centers handling high volumes of standard packages.
-
-
3D Intelligent Sorter (Mini Pick)
-
How it works
- Equipped with AI sensing and smart navigation, these robots use visual recognition and robotic arms to perform intelligent item picking and sorting.
-
Features
- High accuracy sorting, suitable for dynamic order requirements.
- Can automatically adjust item orientation, ideal for irregular and precision goods.
- Great for store restocking and returns handling.
-
Applications
- In-store replenishment (e.g., supermarkets, retail).
- Returns centers (smart recognition of various goods for efficient processing).

| Type | Representative Equipment | Core Technology | Ideal Use Case | Application Scenarios | Advantages | Limitations |
| Traditional Conveyor | Roller/Belt Conveyor | Mechanical conveyors + photo sensors | Large batches of standardized items | Express hubs, large-scale warehouses | Stable, reliable, good for volume | Inflexible, not ideal for round/rolling items |
| Cross-Belt Sorter | Cross-belt conveyor | High-speed transport + barcode scan | Small parcels, high efficiency | E-commerce, apparel, small goods | Fast, accurate | Higher cost, large footprint |
| Sliding-Shoe Sorter | Push plates, sliders | Mechanical arm + sensors | Flexible packaging types | Retail, 3C electronics, food logistics | Gentle, adaptable | Slower sorting speed |
| High-Speed Putwall Sorter | Flash Pick | Integrated picking + fast transport | Promo periods, standardized goods | E-commerce, FMCG, pharma logistics | High throughput, good for promotions | Limited for irregular items |
| 3D Intelligent Sorter | Mini Pick | Smart navigation + AI sensors | High accuracy & flexibility | In-store restocking, returns management | Highly precise, handles complex orders |
High technical demand, higher setup cost |
Conclusion & Selection Recommendations
Each type of automated sorter has unique strengths and is suitable for specific industries and needs:
raditional Conveyor Sorters:
Best for standardized, high-volume items (e.g., food, household goods).
Cross-Belt Sorters:
Best for small, frequent parcels (e.g., e-commerce, courier).
Sliding-Shoe Sorters:
Ideal for varied packaging (e.g., electronics, pharmaceuticals).
High-Speed Putwall Sorters (Flash Pick):
Ideal for standardized goods during sales peaks (e.g., clothing, books).
3D Intelligent Sorters (Mini Pick):
Best for high-accuracy or irregular items (e.g., retail restocking, returns).
