The evolution history of the linear cross belt sorter can be summarized as the following stages:

1. Early stage (1960s and 1970s)
The concept of linear cross-belt sorter first appeared in the late 1960s and early 1970s, mainly used in postal, express and other industries, the purpose is to improve the efficiency of goods sorting. The original device was simple in structure, consisting mainly of a linear conveyor belt and a fixed track.
2. Technological Innovation (1980s)
After entering the 1980s, with the gradual development of automation technology, the design of the linear cross-belt sorter was gradually improved, and more sophisticated control systems and sensors were added, so that the sorter could automatically identify item information (such as bar code scanning). This stage also adds a high-speed transmission system, which greatly improves the sorting efficiency.
3. Multi-function integration (1990s)
In the 1990s, the cross-belt sorter began to add more intelligent elements, enhancing the sorting accuracy and flexibility. In addition to the original bar code scanning, the system began to support RFID technology to achieve more accurate and efficient item tracking and sorting.

4. High speed and modularity (2000s)
After entering the 21st century, with the further development of electrification and mechanization, the speed and processing capacity of linear cross-belt sorters continue to improve. Modular design is becoming mainstream, allowing systems to be expanded and customized to accommodate more complex logistics needs.
5. Intelligence and Digitalization (2010s to date)
In recent years, with the application of big data, Internet of Things (IoT), and artificial intelligence (AI) technologies, modern linear cross-belt sorters have not only high-speed and efficient sorting capabilities, but also self-diagnosis, fault warning, and optimization of sorting strategies. These innovations make the sorter more adaptable, accurate and efficient.

6. Future development trend
With the continuous progress of technology, the linear cross belt sorter still has room for further improvement. In the future, with the development of artificial intelligence, machine vision, and robot technology, the sorting system may further develop in the direction of intelligence and unmanned:

Intelligent sorting system: Combined with AI algorithms, the sorting system can automatically adjust sorting strategies and predict order volume fluctuations, thereby optimizing resource allocation.
Collaborative robots (Cobots) : Sorting systems that collaborate with robots will become more common, and the flexibility and agility of robots can further improve sorting efficiency.
Big Data and Cloud computing: Data monitoring and real-time adjustment through the cloud platform ensure the efficient operation of the sorting system.
Miniaturization and customized design: With the diversification of items and storage environments, future sorting equipment will be more miniaturized and able to adapt to different business needs.

In summary, the development of the linear cross-belt sorter has experienced a process from simple mechanization to highly intelligent, gradually integrating modern automation, digitalization and intelligent technology, which greatly improves the sorting efficiency of the logistics and warehousing industry.
