Overview of sorting chain in logistics and postal industry
06-10-2025 189
In the era of e-commerce and online business boom, the time for sorting goods accounts for up to 50% of the total delivery time, so the application of modern technology to this stage is an inevitable need. The sorting line was born as a breakthrough solution, helping logistics and express delivery businesses significantly shorten the time for processing parcels.
Equipped with advanced technology such as linear synchronous motors, the system not only increases sorting efficiency but also optimizes energy efficiency. This is a clear demonstration of the role of automation in improving productivity, reducing operating costs and ensuring near-absolute accuracy in the sorting process.
What is a sorting line in the logistics and postal industry?
A sorting line in the logistics and postal industry is a modern industrial solution, replacing humans in performing most of the goods sorting stages. Instead of manual work, the system is integrated with machinery, equipment and automation technology to divide products according to many different characteristics such as: color, size, weight or barcode according to established requirements.
The sorting process is operated based on barcode scanning technology on each parcel. After retrieving data from the server, the system will automatically identify the appropriate dividing door with a predetermined IP address, ensuring accuracy and processing speed. A complete sorting production line usually consists of two main components: the product dividing conveyor system and automatic DWS (measurement - weighing - scanning) devices.

Types of systems in the current popular product sorting line
Currently, there are many types of classification systems widely used, suitable for the characteristics of each production and transportation field.
Product sorting line by weight
This system uses weight sensors to determine the weight of each package. Depending on the weight, the product will be brought to the appropriate area thanks to equipment such as conveyor scales, loading robots, etc. This is a popular solution in the food, chemical, and pharmaceutical industries where weight is a key factor in quality control.

Product sorting line by height
Using sensor technology or a measuring system, this line sorts products based on height. The solution is especially suitable for the packaging industry, transporting electronics or products with irregular shapes.
Product sorting line by color
The system uses cameras or optical sensors to recognize colors. Similar colored products are grouped together, while different colored products are moved to another area. This solution is often applied in the food, textile, and light industrial manufacturing industries.

Barcode Sorting Line
This is the most widely used system in the logistics and postal industry. Each product has a barcode or QR code containing detailed information. The scanning system will automatically sort the goods to the correct sorting door, helping to increase processing speed and reduce errors almost absolutely.

Product sorting line by size
Using sensors to measure length, width and height, this system sorts products by size. Very suitable for the manufacturing of household appliances, electronic components or industrial products with a variety of sizes.
Pick to Light feature in the sorting line
In the sorting line and product sorting line, Pick to Light is being trusted by many corporations and large enterprises. This is a system that supports picking and sorting operations using LED signals, helping operators easily determine the location to operate. Outstanding features of Pick to Light:
-
Intuitive LED guidance: When there is a product that needs to be sorted or taken out, the light will turn on at the corresponding location, minimizing errors during operation.
-
Increase processing speed: Workers do not need to search manually, thereby shortening the operation time.
-
Reduced error rate: Thanks to visual display, the error rate is almost zero, ensuring accuracy in sorting.
-
Easy integration: The Pick to Light system can be directly connected to the production line or warehouse management system (WMS, ERP), helping to synchronize data and optimize the entire process.
-
Thanks to this feature, businesses in logistics, post offices, e-commerce, motorcycle and automobile manufacturing, and industrial manufacturing can improve work efficiency and improve customer experience thanks to high speed and accuracy in order processing.

Benefits of sorting lines in the transportation industry
To process goods at high speed, accurately and cost-effectively, the application of sorting lines (also known as product sorting lines) has become the optimal solution, bringing many practical values in warehouse and logistics operations.
Improve labor productivity
The sorting line allows businesses to process large quantities of goods up to 12,000 parcels/hour, thanks to the ability to automate the sorting process. The system uses smart conveyors, barcode scanners and sensors to determine the destination of each parcel, helping to free up human labor, ensuring fast operating speed, meeting the needs of delivery in a short time.
Reduce goods processing time
Thanks to fully automated operation, the product sorting line helps to significantly shorten order processing time. Parcels are sorted quickly and consistently, thereby delivering goods to customers on schedule.

Outstanding accuracy
The sorting line system uses optical technology, AI cameras and barcode scanners to achieve up to 99.8% accuracy in sorting. This minimizes address confusion or errors during transportation.
Minimize errors and lost goods
One of the major problems in the express delivery industry is lost and incorrect goods. With an automatic product sorting line, human dependence is significantly reduced, thereby minimizing the rate of lost and damaged goods.
Support effective warehouse management
The sorting line system is often integrated with warehouse management software (WMS), allowing businesses to track the status of goods in real time. Thanks to that, inventory management, monitoring of goods flow and optimizing warehouse operations become more accurate and transparent.
Improve business competitiveness
When delivery speed and accuracy are improved, businesses can increase customer experience, retain old customers and attract new customers. This is an important factor that helps businesses improve their competitive position in the fierce express delivery market.
In the express delivery and logistics industry, investing in an automatic sorting line not only helps increase productivity and accuracy, but also contributes to minimizing risks, optimizing warehouse management and improving competitiveness.
