3、產(chǎn)流水線的控制，重點分析了系統(tǒng)軟硬件設(shè)計部分，并給出了系統(tǒng)硬件接線圖、PLC控制I/O端口分配表以及整體程序流程圖等，實現(xiàn)了飲料灌裝的自動化，提高了生產(chǎn)效率，降低了勞動強度。傳統(tǒng)的飲料罐裝生產(chǎn)線的電氣設(shè)備控制系統(tǒng)是傳統(tǒng)的繼電器——接觸器控制方式,在使用的過程中，生產(chǎn)工效低，人機對話靠指示燈+按鈕+訊響器的工作方式，響應(yīng)慢，故障率高，可靠性差，系統(tǒng)的工作狀態(tài)、故障處理、設(shè)備監(jiān)控與維護只能憑經(jīng)驗被動的去查找故障點。且在生產(chǎn)過程中容易產(chǎn)生二次污染，造成合格率低，生產(chǎn)成本增加。而自動化生產(chǎn)線在眾多領(lǐng)域應(yīng)用得非常廣泛，其控
4、制部分常常采用PLC控制，它使自動化生產(chǎn)線運行更加平穩(wěn)，定位更加準確，功能更加完善，操作更加方便。關(guān)鍵詞：PLC；自動化飲料灌裝生產(chǎn)線；系統(tǒng)硬件接線圖；I/O端；分配表目錄一、系統(tǒng)概況··········································51、生產(chǎn)工藝及流程······································5二、設(shè)計任務(wù)··········································51、課題容······················
