Description

Cross sorting trolley device

Technical Field

The utility model relates to a commodity circulation letter sorting equipment technical field especially relates to a cross sorting dolly device.

Background

Compared with the traditional manual sorting, the automatic sorting system has the advantages of high sorting efficiency, capability of continuously working for a long time, no violent sorting and the like, but the popularization degree of the automatic sorting system in the logistics industry of China is unsatisfactory in recent years. According to research, at present, the provincial hub of each major provincial meeting city in China basically adopts an automatic sorting system to a certain extent, but in the hub of a district, a general city and a county, especially a northwest city, express delivery points mostly use a manual sorting mode. Through on-site research, the dilemma met by the popularization of the automatic sorting system is mainly that the construction and maintenance cost of the automatic sorting system is generally higher, and the price of the sorting equipment in the current market is generally calculated according to the number of sorting ports, and each sorting port is more than 1.5 ten thousand yuan. For example, an automated system with 80 sorting ports needs to invest at least 120 ten thousand yuan at a time, which is unbearable for a general logistics enterprise express delivery point.

At present, the common automatic sorting systems in domestic and foreign markets mainly have three types: cross belt sorters, slider sorters, and baffle sorters. Among them, the cross belt sorting method is widely adopted because of its advantages such as wide sorting range and strong sorting ability, and representative manufacturers include van der de, FKI, Cinetic, berman machine and inteno. The main principle is that a cross sorting trolley is operated on an annular track, and an electric roller is arranged on the sorting trolley. When the sorting trolley reaches the designated outlet position, the conveying belt of the sorting trolley is driven by the electric roller to drive the packages to drive away from the trolley. Each trolley needs an electric driving power device and mostly adopts a sliding rail for power supply, and the mode has higher cost.

In order to solve the problem of power supply cost of the cross sorting trolley, at present, some patents propose unpowered cross sorting trolleys, for example, chinese patent application with publication number CN110127310A, in which a friction wheel is installed at the bottom of the sorting trolley, the friction wheel is in transmission connection with a roller inside the sorting trolley through a bevel gear, a friction plate driven by an air cylinder is installed between sorting slide rails, when the sorting trolley moves above the friction plate on the sorting slide rails, the air cylinder drives the friction plate to rotate so that the friction plate contacts with the friction wheel, and the friction wheel starts to rotate during the moving process of the sorting trolley so as to drive a conveying belt on the sorting trolley to rotate, so that the rapid sorting is completed. Although this patent has realized unpowered letter sorting, the mode reliability that adopts friction pulley and friction plate contact is not high, and the drive power that provides is also very limited moreover, and the contact position of friction pulley and friction plate is only a line, and the friction pulley can slide in the contact twinkling of an eye inevitably, and long-time work can cause the wearing and tearing of friction pulley or friction plate and then influence the normal clear of letter sorting work certainly, and is also very unfavorable to reducing the maintenance cost.
