nd programming simple, easy to use and small size, light weight, a series of lowpower advantages in industrial applications bee more extensive. This paper focuses on the PLC in the canned beverage production, The design of an automatic sorting device with low cost and high efficiency is presented in the paper, which regards programmable logic controller ( PLC) as the master controller and bines pneumatic device, sensing technology, position control and other technology to implement automatic selecting of the products live. The device is characteristic of high automation, steady running, high precision and easy control, which can fulfill the requirement according to different situations with little modifications.Key words: programmable logic controller,sorting device,control system,sensors目錄摘 要 ............................................................................................................................................................I目錄 ..............................................................................................................................................................II緒 論 .............................................................................................................................................................1第 1 章 材料分揀裝置結(jié)構(gòu)及總體設(shè)計(jì) .....................................................................................................2 材料分揀裝置工作過(guò)程概述 ..........................................................................................................2 系統(tǒng)的技術(shù)指標(biāo) ..............................................................................................................................3 系統(tǒng)的設(shè)計(jì)要求 ..............................................................................................................................3第 2 章 控制系統(tǒng)的硬件設(shè)計(jì) .....................................................................................................................5 系統(tǒng)的硬件結(jié)構(gòu) ..............................................................................................................................5 系統(tǒng)關(guān)鍵技術(shù) ..................................................................................................................................5 檢測(cè)元件與執(zhí)行裝置的選擇 ..........................................................................................................8第 3 章 控制系統(tǒng)的軟件設(shè)計(jì) ...................................................................................................................15 控制系統(tǒng)流程圖設(shè)計(jì) ....................................................................................................................15 控制系統(tǒng)程序設(shè)計(jì) ........................................................................................................................16第 4 章 控制系統(tǒng)的調(diào)試 ...........................................................................................................................22 硬件調(diào)試 ........................................................................................................................................22 軟件調(diào)試 ........................................................................................................................................22 整體調(diào)試 ........................................................................................................................................23結(jié) 論 ..................................................................................................
