Description

Linear cross-belt sorter based on industrial carrier

technical field

The invention relates to the technical field of logistics automatic sorting, in particular to a design scheme of an industrial carrier-based linear cross-belt automatic sorting machine equipment.

Background technique

With the rapid development of the e-commerce era, it has also promoted the transformation of the logistics industry. Automated equipment has gradually replaced manual sorting by operators. This situation has higher and higher requirements for logistics automation equipment. For the current logistics sorting Mode, manual sorting is no longer in line with the trend, and sorting machines are gradually used. At present, there are many types of sorting machines, and different types of sorting machines have different working efficiencies. Common automatic sorting machines include circular cross-belt sorters and linear sorters. Although the existing circular cross-belt sorters can sort single items, they are expensive and occupy a large area. Although the type sorter has a low cost and a small footprint, the connection between the trolleys will be worn and deformed due to long-term work, which cannot guarantee the smooth operation of the conveyor belt, and even produces noise. It restricts work efficiency and cannot meet people's current efficiency requirements for new logistics.

In 2015, Wang Daosheng invented a belt-type sorting trolley for a linear cross-belt sorter (authorized announcement number: CN103121583B). Rotating to realize the sorting of single items, not only can sort regular items, but also sort soft-packed items or irregular objects. The disadvantage is that the power source is unstable, which makes the sorting line run smoothly; in 2017, Zheng Aiquan et al. Invented an intelligent linear cross-belt sorter and its working method (application publication number: CN107377401A), its advantage is that by setting the main body of the upper charter machine on both sides of the sorter body, the setting of the identification mechanism is consistent with the upper charter machine The address, weight and volume of the goods on the main body are identified. When the goods reach the transmission mechanism, the control system will arrange several cars to transport them according to the volume of the goods, so as to realize the reasonable allocation of resources. The whole working process is simple and easy to realize. It also improves the speed and accuracy of goods sorting; its disadvantage is that the position of the goods will change due to the influence of other factors on the conveyor belt, and the relative position will be offset when they reach the sorting belt, which will make the sorting time An error occurred. In 2018, Wu Jiachun invented a single-drive linear cross-belt sorter (authorized announcement number: CN208082910U), which has the following advantages. The left and right driving wheels are driven by motors, and the upper and lower straight parts of the rubber chain have traction power, which increases the stress point of the rubber chain, which reduces the tension on the rubber chain and improves the performance of the ring power, effectively improving The service life of the rubber chain; the disadvantage is that the rubber chain will age after a period of use and become loose, making the entire conveyor belt a safety hazard.
