The traditional relay is used to control to the traditional production line in use process will appear, low production efficiency and response speed, high failure rate, poor reliability and the working state of the system, fault handling, equipment condition monitoring and maintenance can only experience a passive find fault point. And second failures occur easily, the product pass rate is very low, so that the production cost bees more. However, with the progress of science and technology, beverage filling production line process is towards automation and intelligent development goals. But in consideration of the production line operators and electrical maintenance workers of the actual knowledge level, a single instruction mode of ladder diagram based on using user program image. To learn。 debugging and error checking is also very convenient, it is very important. In this paper, the application of programmable logic controller (PLC) in the beverage filling production line PLC powerful in factory production lines in the application. And gives the structure chart of the relevant address allocation table, etc. Keywords: filling production line。 PLC。 sensor 目 錄 摘要 ...................................................................2 ABSTRACT ..............................................................3 共 頁 第 10 頁 ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ 裝 ┊ ┊ ┊ ┊ ┊ 訂 ┊ ┊ ┊ ┊ ┊ 線 ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ 前言 ..................................................................6 .......................................7 任務(wù)的分析 ........................................................7 硬件方案設(shè)計(jì) . ...................................................7 軟件方案設(shè)計(jì) . . ..................................................8 經(jīng)驗(yàn)設(shè)計(jì)法 ...................................................8 邏輯設(shè)計(jì)法 ...................................................9 ....................................................10 PLC 的簡介 .......................................................10 PLC 的選擇原則 ...............................................12 PLC 的型號確定 ..............................................13 電動機(jī)的選擇 . ..................................................13 接觸器的選擇 . ..................................................14 熱繼電器的選擇 . ................................................14 開關(guān)電器、熔斷器的選擇 . ........................................15 傳感器的選擇 . ..................................................15 ....................................................16 系統(tǒng)硬件結(jié)構(gòu) . ..................................................16 主電路的設(shè)計(jì) . ..................................................16 控制電路的設(shè)計(jì) . ................................................16 操作面板的設(shè)計(jì) . ................................................17 ....................................................18 共 頁 第 11 頁 ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ 裝 ┊ ┊ ┊ ┊ ┊ 訂 ┊ ┊ ┊ ┊ ┊ 線 ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ 控制要求以及控制過程的分析 . ....................................18 系統(tǒng)流程圖 ..................................................18 PLC控制系統(tǒng)的 I/O分配 .......................19 程序 .............................................................20 初始化程序 ..................................................20 裝箱選擇程序 ................................................21 流水線主控程序 .............................................22 閃爍報(bào)警程序 ................................................23 計(jì)數(shù)程序 ....................................................23 數(shù)據(jù)傳送程序 ................................................25 . ......................................................25 裝箱選擇程序的仿真 . ............................................26 主控制程序的仿真 . ..............................................26 閃爍報(bào)警程序的仿真 . ............................................29 計(jì)數(shù)程序的仿真 . ................................................30 結(jié)束語 . .............................................................31 參考資料 . ...........................................................32 前 言 目前，飲料的灌裝的自動化生產(chǎn)已經(jīng)基本普及，為了進(jìn)一步 增強(qiáng)生產(chǎn)產(chǎn)品的質(zhì)量，減少生產(chǎn)時(shí)間，提高產(chǎn)能，以適應(yīng)顧客對產(chǎn)品要求的快速升級。產(chǎn)品生產(chǎn)正向縮短生產(chǎn)周期，降低生產(chǎn)成本，提高生產(chǎn)質(zhì)量等方面發(fā)展。因此飲料廠的自動化灌裝生產(chǎn)線中有更多的機(jī)械設(shè)備在使用先進(jìn)的生產(chǎn)線灌裝技術(shù)來提升機(jī)械設(shè)備的自動化控制水 共 頁 第 12 頁 ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ 裝 ┊ ┊ ┊ ┊ ┊ 訂 ┊ ┊ ┊ ┊ ┊ 線 ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ 平和生產(chǎn)效率。而就目前來講自動化生產(chǎn)的電氣控制部分的主要進(jìn)軍方向就是 PLC針對電氣
