Reform of High-rack Storage with Manipulator
For overcoming the shortcomings including redundant structure,outdated equipment and lacking maintenance of the high-rack storage,a reform project is proposed trying to utilize the old equipments.First,a new updated structure is shown in this paper.Second,based on the analysis of the stacker's function and with the help of the conception of software engineering,a modular approach is used to design this program so that the productivity can be greatly increased.Thirdly,this paper analyzes the modulization's disadvantage and the remedies are followed.In addition,a velocity-control scheme is proposed based on the frequency converter with DRIVECOM interface.After practical running,the HMI with wincc is friendly and PLC program is reliable.
