1、遼寧石油化工大學(xué)畢業(yè)設(shè)計(jì)基于PLC的堆垛機(jī)控制系統(tǒng)設(shè)計(jì)摘要在現(xiàn)代的物流倉(cāng)儲(chǔ)系統(tǒng)中,自動(dòng)化立體倉(cāng)庫(kù)應(yīng)用日益廣泛。而堆垛機(jī)是立體倉(cāng)庫(kù)的關(guān)鍵組成部分,堆垛機(jī)性能的優(yōu)劣對(duì)整個(gè)立體倉(cāng)庫(kù)的運(yùn)行起到至關(guān)重要的作用,所以設(shè)計(jì)與開發(fā)自動(dòng)化程度較高的堆垛機(jī)控制系統(tǒng)成為當(dāng)前立體倉(cāng)庫(kù)的發(fā)展趨勢(shì),開展與此有關(guān)的研究具有重要的理論和應(yīng)用價(jià)值。本文基于現(xiàn)代物流技術(shù)的應(yīng)用和發(fā)展要求,介紹自動(dòng)化立體倉(cāng)庫(kù)的應(yīng)用及其功能和作用,結(jié)合現(xiàn)代科技的發(fā)展,著重研究自動(dòng)化立體倉(cāng)庫(kù)堆垛機(jī)控制系統(tǒng)的控制技術(shù)。本文詳細(xì)闡述了本控制系統(tǒng)的設(shè)計(jì)思想,以及整個(gè)系統(tǒng)的硬件實(shí)現(xiàn)和軟件設(shè)計(jì)。論文依據(jù)立體倉(cāng)庫(kù)的有關(guān)設(shè)計(jì)參數(shù),對(duì)堆垛機(jī)電氣控制
2、的硬件系統(tǒng)進(jìn)行了設(shè)計(jì),為了提高堆垛機(jī)的性能,本文采用了轉(zhuǎn)速、位置反饋的雙閉環(huán)控制,以滿足系統(tǒng)的調(diào)速要求。系統(tǒng)的水平認(rèn)址采用激光測(cè)距傳感器定位,垂直認(rèn)址采用光電開關(guān)和認(rèn)址片組合定位。變頻調(diào)速系統(tǒng)由S7-200PLC及其擴(kuò)展模塊EM235通過(guò)變頻器MM440控制交流電動(dòng)機(jī),采用光電編碼器反饋轉(zhuǎn)速信號(hào),實(shí)現(xiàn)轉(zhuǎn)速閉環(huán)控制。貨叉伸叉系統(tǒng)由S7-200PLC通過(guò)步進(jìn)電動(dòng)機(jī)驅(qū)動(dòng)器SH-20403控制二相混合式步進(jìn)電動(dòng)機(jī)。根據(jù)系統(tǒng)的控制要求進(jìn)行了PLC、變頻器、電機(jī)和電機(jī)驅(qū)動(dòng)器的選型,并給出了系統(tǒng)的硬件接線圖,然后利用西門子的編程軟件step7設(shè)計(jì)了堆垛機(jī)控制程序。關(guān)鍵詞自動(dòng)化立體倉(cāng)庫(kù),堆
