Description

A straight-fall secondary sorting system

technical field

The invention relates to a box-shaped article sorting system, in particular to a high-speed, low-error-rate straight-fall secondary sorting system suitable for many types of miniature articles, and belongs to the field of logistics machinery.

Background technique

The sorting system is widely used in logistics, transportation, postal services, factory production and many other fields of production and life, especially in logistics distribution, tobacco, beer beverage, food, auto parts and other industries. It is to improve the efficiency of logistics distribution, A key element in increasing production efficiency and reducing logistics and production costs. Efficient sorting systems have become an indispensable part of large and medium-sized logistics centers in developed countries.

Sorting is an important part of the logistics system. The level of sorting efficiency will directly affect the cost of logistics distribution. A sorting system with high efficiency, high precision and low error rate will greatly improve the efficiency of the logistics system. Reduce logistics and distribution costs.

Only by ensuring high-precision system operation and mechanism action can the mechanism be improved. Reliability can reduce mechanism failures and ensure efficient operation of the system; the error rate of the sorting system determines the availability of the mechanism. Only when the error rate is kept low or even zero can the sorting system have practical significance. Therefore, it is of great significance to study a sorting system with high efficiency, high precision and low error rate.

After domestic and foreign literature retrieval and research on related equipment publicly used in China, it is found that there are two main types of sorting systems currently used at home and abroad:

One is to use a belt or a roller table as a conveying device for side push sorting;

The other is to use the chain to drive the tray as the conveying device for flip-type sorting. Although these two sorting methods have the characteristics of high efficiency and low error rate for large items, it is difficult to achieve accurate positioning of items and control the correct posture of items after sorting, especially for miniature items with a length of less than 10 cm. Its high-speed sorting. In view of the need for sorting of small items required by industries such as medicine and electronic components, and the limitations of the current sorting system functions, it is necessary to develop a new form of sorting system.
