Abstract
In order to meet the requirement of high efficiency, high accuracy, high reliability and high expansibility of stacker. The stacker control system based on motion controller is developed,which uses digital control technology of NC machine tools for reference and adopts the half closed loop control system of motion controller and servo drive system to realize high efficiency, high precision and high reliable motion control of stacker.Using the network interface of controller interact with the logistics system server, storage management, computer information management system of ERP, AGV car, palletizing robot and other equipment.Make it becomes the organic part of the logistics system,which provides a good solution to improve the level of enterprise logistics automation.
Highlights
Stereoscopic warehouse is an important component of the intelligent logistics system
Protection mechanism, overload protection device and limit protection device for each movement direction.The structural and mechanical properties of stacker meet the principles of strength, stiffness and reliability principle.The weight of each part should be reduced to minimize the impact of inertial impact on the acceleration, braking and operation of the stacker.At the same time,manufacturing costs can be reduced [4]
The major function is servo driver inside the electrical cabinet drive the servo motor that is mounted on the lower cross member of stacker.The gear on the motor output shaft meshes with the rack on the floor rail so that the stacker can move horizontally in order to realize the column positioning of the goods in storage.A walking wheel is arranged on one side of the lower cross beam, and a guide wheel is arranged on the other side, which plays a good guiding role in the smooth operation of the stacker.When the overload and stall conditions, servo driver will execute the overload protection, the motor will perform brake
Summary
Stereoscopic warehouse is an important component of the intelligent logistics system. It is the key link of the warehousing and transportation system. It is the result of the development of logistics and storage system and the progress of information technology [1]. the warehouse has been developed integrated software product that consists of the mechanical and electrical combination, combination of strong current and weak current control, automatic feeding system, automatic sorting system, automatic control system, AGV transport system, automatic stacking stack system and host computer control software [2].Compared with the traditional platform warehouse and floor warehouse, it has incomparable advantages.It is the key node in the intelligent factory and Internet of things system. Protection mechanism, overload protection device and limit protection device for each movement direction.The structural and mechanical properties of stacker meet the principles of strength, stiffness and reliability principle.The weight of each part should be reduced to minimize the impact of inertial impact on the acceleration, braking and operation of the stacker.At the same time ,manufacturing costs can be reduced [4]
