Description

A hydraulically driven rotary separation type lifting conveyor and its application

Technical field

The invention relates to a hydraulically driven rotary separation type lifting conveyor and its application, and belongs to the technical field of storage logistics equipment.

Background technique

With the rapid development of industrial technology today, due to the passivity, discontinuity, and imbalance of traditional storage methods and the social background of rising land prices, material handling and transportation can be completed efficiently under the premise of low cost. Storage has become a way of supplying goods that companies have always pursued. Therefore, as the requirements for the supply line of "production→warehousing→distribution" continue to increase, the warehousing method has evolved from a simple accumulation of manpower by relying solely on workers to a warehouse assisted by semi-automatic equipment such as forklifts. In the end, it changed to an automated three-dimensional warehouse system with automatic equipment such as stackers, rail shuttles, and automatic guided transport vehicles. The automated three-dimensional warehouse is a large-scale storage system that uses high-level shelves to store materials through computer management and control, and is accessed by automatically controlled lane stackers and other handling equipment.

The development period of automated three-dimensional storage equipment coincided with the emergence of public opinion about the tobacco control movement in my country's tobacco industry, as well as the backward management model and relatively low productivity. Therefore, the tobacco industry took the express train of the automated three-dimensional warehouse and realized the transformation of the entire industry. The current automated warehousing system has been widely used in the tobacco industry. It is mainly used for the formulation of raw materials and the storage, transportation, sorting and distribution of tobacco shreds, auxiliary materials and finished cigarettes. It is second only to silk making workshops and rolls in tobacco companies. The third largest workshop of the workshop.

However, many tobacco companies still have many problems in the process of designing and using automated three-dimensional warehouses: for example, the conveying capacity does not match the actual demand, the arrangement of the equipment in front of the warehouse is unreasonable, the accuracy of semi-automatic tray distribution is low, and the conveying process will Material interference occurs. The existence of these defects will not only affect the work progress of the entire automated warehouse, but also may cause the labor safety of the warehouse staff to not be guaranteed. Hereby optimize the design of the conveyor system in front of the automated warehouse.
