3.控制方案的實現(xiàn)
當車間工人把84毫米長的過濾咀香煙碼放在煙庫內(nèi)并起動機器,機器就以
每分鐘120-140包的速度生產(chǎn)出按一定規(guī)律排放好的硬盒香煙,然后封裝好透明紙貼好金黃色的拉線。盡管機器的生產(chǎn)速度很高,工藝動作要求復雜,只要充分利用PLC本身的特點,再結(jié)合生產(chǎn)實踐,我們開發(fā)了一套簡捷周密的邏輯控制方案,完全滿足所有工藝要求。
系統(tǒng)中使用了35個開關(guān)量輸入信號,10個開關(guān)量輸出信號。程序中應(yīng)用了9種基本指令,10種功能指令(如INC,MOV,BMOV,CMP,SFTL,ADD等),8個定時器,6個計數(shù)器,8個指針,28個數(shù)據(jù)寄存器(含斷電保持型),共1100條語句。整個程序不僅實現(xiàn)了全部工藝要求,而且還增加了許多輔助功能,如生產(chǎn)時間和停機時間的統(tǒng)計顯示,故障頻次的統(tǒng)計,成品產(chǎn)量與廢品剔除數(shù)量統(tǒng)計,日期時間顯示,日產(chǎn)量班產(chǎn)量報表的生成打印輸出等功能。此外還允許操作工人對一部分運行數(shù)據(jù)進行在線修改,利用人機界面上的觸摸開關(guān)即可實現(xiàn)。
由于PLC本身的可靠性高,抗干擾能力強及有在線修改的能力,使我們的控制系統(tǒng)聯(lián)機調(diào)試調(diào)整時間大大縮短,幾乎省去了現(xiàn)場服務(wù),一般操作工人或維修電工均可勝任調(diào)試工作。所以受到了廠家的普遍好評。
產(chǎn)品廣泛應(yīng)用于:電力、石油、礦井提升、港口、供熱、燃氣、供水、污水處理、冶金、造紙、紡織、化工、水利等現(xiàn)代化工業(yè)領(lǐng)域!
