Description

A vehicle-mounted portable intelligent express sorting and filling system

technical field

The invention relates to the technical field of logistics, in particular to a vehicle-mounted portable intelligent express sorting and filling system.

Background technique

In the 1970s, express delivery service entered my country as an advanced postal and transportation service method. After nearly 30 years of development, my country's express delivery industry has grown from nothing to large, and has now become the fastest growing and most dynamic part of the world's express delivery market. At present, the scale of China's express delivery market has exceeded 20 billion, and it is still growing at a rate of more than 30% every year. In the 21st century, my country's express delivery industry has developed rapidly, and the average daily express delivery volume has increased from 3 million to 13 million. The ever-increasing express delivery has also created problems such as slow delivery, low efficiency, high missing parts rate, and high labor costs. With the above problems, express cabinets came into being. It has been more than 10 years since the construction of foreign self-service express stations. From its mature market experience, express cabinets entering the community must be a social trend. At present, nearly 20 countries around the world have begun to apply construction, with different models. Taking Hangzhou as an example in China, more than 20 express delivery companies have been registered and used in express cabinets, including almost all express delivery companies. In terms of utilization rate, social express (third-party express delivery outside postal enterprises) accounted for 93%. Express cabinets are rapidly gaining popularity in today's world.

The popularization of express cabinets has brought many new challenges to couriers. Among them, how to ensure the rapidity and reliability of detection, sorting and filling in the process of processing a large number of express mail is a very important issue. At present, most small and third-party logistics express companies in China still use the traditional classification and filling method, relying on a lot of manpower to realize the classification and filling of express mail. The existing manual filling and classification method is inefficient and prone to errors, and cannot meet the requirements of the growing express delivery industry. In addition, because express parcels are non-standard products, the dimensions are different, which also brings difficulties to sorting. For this, we need a time-saving and efficient automatic sorting, filling system.

At present, there are two representative design schemes of express sorting and filling system at home and abroad:

An RFID-based item sorting system. The main implementation method is: sticking RFID tags on the packages, and achieving the purpose of automatic sorting through RFID identifiers, communication modules, control centers and sorting equipment. It is undeniable that RFID technology is very suitable for logistics with its efficient reading and writing characteristics, but each package needs to be pasted with RFID tags, which is complicated and costly. In addition, its imperfect feedback mechanism and high cost also make this kind of system extremely low in the domestic market. And due to the large number of express shipments per day in China, the system cannot change the existing domestic problems well.

An automatic scanning and sorting device for express mail of express companies. The device realizes the functions of express automatic scanning and sorting through express conveyor belts, manipulators, fixed gun cameras, barcode scanners, light sensors, express distributors, computer controllers and other devices. The device is simple in structure and stable in operation, and can realize automatic sorting of express mail without manpower. Although the work efficiency and sorting accuracy have been improved, the use of manipulators inevitably increases the cost of products, and it is difficult to popularize on a large scale in China.

A summary of the previous background: Although the existing domestic self-service lockers have realized the intelligent storage function, they ensure the safety of customers' express shipments and facilitate customers to access express products in their spare time. However, the common problem is that a large number of express items still need to be sorted and filled by couriers one by one, which is inefficient and labor-intensive. To solve this problem, we designed a vehicle-mounted portable intelligent express sorting and filling system. The system is mainly used for small and medium-sized express delivery vehicles to classify and fill express, which improves the efficiency of classification and filling, and solves the process of handling, classification, filling and other processes that need to be carried out by manual work, as well as the problem of excessive physical strength.
