1. Overview

1.1 Equipment Introduction

Cross-belt sorter is consists of continuous carriages, rail, induction, sorting crossing, and barcode scanner. The goods are automatically guided into the sorter carriage smoothly through the induction station, and the goods are smoothly unloaded to the designated slot through the movement of the carriage belt after the scanner reads the code and the database address query. Cross-belt sorter is widely used in express, e-commerce, clothing, food, cosmetics, airports, medicine and other industries.
