簡(jiǎn)介：棉花打包機(jī)作為棉花加工企業(yè)中的一種重要設(shè)備，其作用和地位都是不可替代的。而控制系統(tǒng)對(duì)棉花打包機(jī)能否正常生產(chǎn)起著決定性的作用。自從我國(guó)實(shí)行棉花質(zhì)量檢驗(yàn)體質(zhì)改革以來(lái)，國(guó)內(nèi)許多棉花打包機(jī)的控制系統(tǒng)已經(jīng)難以滿足現(xiàn)實(shí)生產(chǎn)的要求，進(jìn)行更新?lián)Q代勢(shì)在必行。本課題以下項(xiàng)式雙箱液壓打包機(jī)控制系統(tǒng)的電氣化改造為背景，通過(guò)對(duì)棉花打包的生產(chǎn)工藝、打包機(jī)的結(jié)構(gòu)組成以及生產(chǎn)環(huán)境進(jìn)行調(diào)研和分析，提出了應(yīng)用可編程序控制器PLC為主要控制單元的控制系統(tǒng)來(lái)替代原有繼電接觸控制系統(tǒng)的方案。以PLC控制系統(tǒng)的實(shí)現(xiàn)為研究重點(diǎn)，仔細(xì)分析了棉花打包機(jī)的控制要求，設(shè)計(jì)了一套基于PLC的控制系統(tǒng)，完成了系統(tǒng)的硬件設(shè)計(jì)、軟件程序設(shè)計(jì)以及人機(jī)界面監(jiān)控系統(tǒng)的設(shè)計(jì)。分析了對(duì)棉花打包機(jī)實(shí)現(xiàn)棉包重量控制與調(diào)節(jié)的方法，采用壓力計(jì)量的方式對(duì)棉包重量進(jìn)行控制。采用壓力變送器采集到踩棉預(yù)壓壓力信號(hào)，經(jīng)過(guò)AD轉(zhuǎn)換之后得到的數(shù)字量與PLC內(nèi)部設(shè)定值進(jìn)行比較，確定棉包重量是否到達(dá)要求。此外，還考慮了回潮率對(duì)棉包重量的影響，對(duì)棉包的回潮率進(jìn)行檢測(cè)，并根據(jù)檢測(cè)結(jié)果對(duì)棉包重量進(jìn)行調(diào)節(jié)。論文結(jié)合機(jī)電一體化系統(tǒng)可靠性的相關(guān)理論，分析了影響棉花打包機(jī)控制系統(tǒng)可靠性的因素。根據(jù)分析結(jié)果將影響棉花打包機(jī)控制系統(tǒng)可靠性的主要因素分為現(xiàn)場(chǎng)干擾和系統(tǒng)故障這兩類(lèi)。結(jié)合打包機(jī)的現(xiàn)場(chǎng)工作條件提出了一系列提高棉花打包機(jī)控制系統(tǒng)可靠性的相關(guān)措施。
