零件自动存放系统的设计–控制系统设计

Design of automatic storage system for parts-Controlsystem designAbstractWith the "made in China 2025"plan put forward by premier li keqiang,thedomestic automation control technology has developed rapidly in recent years,andnow many industries are inseparable from the shadow of automation control.Forexample,in the logistics industry,the warehouses of some large companies haverealized the full automatic sorting,packaging and transportation of packages.Theaddition of this technology not only reduces 75%of the workers in the warehouses,but also greatly improves the working efficiency and reduces the retention ofpackages.And as manufacturing industry,the ubiquity of automation controltechnology,many enterprises by the automation of production equipment upgradingand modification are on the path of transformation,all kinds of"unmanned factory","black lamp factory"to become a reality,the concept of automation controltechnology to the enterprise brought the rich economic benefit,and is an importantmethod of improve the core competitiveness of enterprises.For most of the current domestic small and medium-sized enterprise CNCnumerical control lathe USES is artificially put parts of the problem,the group intendsto design a material based on programmable controller PLC and pneumatic controlsystem of automatically placing,the purpose is to solve the placement and finishing inartificial process is put into the time is too long,the error rate is high,the moreproblems of choose and employ persons,automatically put high efficiency comparedwith traditional manual put low error rate,put some more,and no artificial operation,reduces the manual labor intensity,improve production efficiency and otheradvantages.The automatic placement system is controlled by mitsubishi FX3U seriesPLC.The system is mainly composed of material delivery module,motor drivemodule,placement module and PLC control module.The material transport module istransported to the placement module by the dc motor through the conveyor belt.Themotor drive module realizes the movement of X and Y axis through the stepper motorand the lead screw to move the parts to the designated position.The placementmodule is a small electromechanical system with a pneumatic device as the executionunit.The placement of parts is realized by opening and closing the fixture devicecontrolled by the cylinder.In addition,the photoelectric sensor,positive and negativelimit switch and proximity switch of X axis and Y axis are also installed on thesystem to provide the position of the workpiece and the detection and reset of the
