【摘要】：包裝機(jī)械是發(fā)展包裝工業(yè)的關(guān)鍵,正向著智能化、自動(dòng)化、高效率、多功能、低消耗方向發(fā)展。筒子紗自動(dòng)包裝機(jī)作為包裝機(jī)械的一種,用于實(shí)現(xiàn)筒子紗的自動(dòng)包裝。 目前,筒子紗主要依靠人工包裝,但隨著筒子紗生產(chǎn)自動(dòng)化程度的提高,人工包裝已經(jīng)無法滿足生產(chǎn)要求,國(guó)外已經(jīng)研究出筒子紗自動(dòng)包裝機(jī),但并不能完全實(shí)現(xiàn)自動(dòng)化,在幾個(gè)環(huán)節(jié)都需要人工的參與,且成本較高。因此開發(fā)具有自主知識(shí)產(chǎn)權(quán)的筒子紗自動(dòng)包裝機(jī)符合我國(guó)紡織行業(yè)的迫切要求。 筒子紗自動(dòng)包裝系統(tǒng)作為一個(gè)高速度、智能化、全自動(dòng)的紡織行業(yè)包裝設(shè)備,是集在線檢測(cè)、精密機(jī)械、實(shí)時(shí)控制于一體的大型包裝生產(chǎn)線,要求各部分協(xié)調(diào)配合,同時(shí)保證整個(gè)系統(tǒng)的可靠性與穩(wěn)定性。本文通過對(duì)筒子紗包裝過程的分析,綜合運(yùn)用了自動(dòng)控制、機(jī)械自動(dòng)化、計(jì)算機(jī)技術(shù)、儀器儀表、通信網(wǎng)絡(luò)等眾多學(xué)科知識(shí),研究與設(shè)計(jì)了筒子紗自動(dòng)包裝系統(tǒng)。 針對(duì)筒子紗自動(dòng)包裝系統(tǒng)中的幾個(gè)關(guān)鍵技術(shù)進(jìn)行了以下幾個(gè)方面的研究： 1、根據(jù)筒子紗包裝的工藝要求,確定了筒子紗自動(dòng)包裝的流程,并提出了“統(tǒng)一控制,分模塊設(shè)計(jì)”的思路,由PLC對(duì)整個(gè)包裝過程進(jìn)行控制,由觸摸屏對(duì)現(xiàn)場(chǎng)進(jìn)行監(jiān)控,通過上位WinCC組態(tài)實(shí)現(xiàn)在控制室對(duì)整個(gè)包裝過程的監(jiān)控和報(bào)表輸出。 2、設(shè)計(jì)了系統(tǒng)的整體方案,從原理上對(duì)比了各模塊實(shí)現(xiàn)的方式,找出最簡(jiǎn)單可靠的設(shè)計(jì)方法,分別設(shè)計(jì)了各模塊的機(jī)械結(jié)構(gòu),并采用氣動(dòng)系統(tǒng)驅(qū)動(dòng)執(zhí)行機(jī)構(gòu),完成包裝過程的各個(gè)工藝流程,對(duì)現(xiàn)有設(shè)備做了選型。 3、研究了氣動(dòng)系統(tǒng)的總體結(jié)構(gòu),從原理上分析了氣動(dòng)元件和配管的配置方法,對(duì)本系統(tǒng)所需要的氣動(dòng)元件進(jìn)行了選型,設(shè)計(jì)了完善的氣動(dòng)系統(tǒng)。 4、設(shè)計(jì)了系統(tǒng)控制單元的硬件結(jié)構(gòu),研究了輸送線的調(diào)速技術(shù)與原理,設(shè)計(jì)了本系統(tǒng)的通訊網(wǎng)絡(luò),根據(jù)本系統(tǒng)設(shè)計(jì)的特點(diǎn),研究了本系統(tǒng)中的硬件抗干擾措施。根據(jù)本系統(tǒng)的硬件結(jié)構(gòu)和系統(tǒng)的控制要求,設(shè)計(jì)了本系統(tǒng)的控制軟件以及各模塊的控制流程；根據(jù)對(duì)監(jiān)控系統(tǒng)的要求,設(shè)計(jì)了上位機(jī)組態(tài)界面；并研究了PLC與系統(tǒng)主要模塊的通信方式。 5、研究了本系統(tǒng)各段輸送線的速度配合策略,設(shè)計(jì)了自適應(yīng)模糊PID控制器,并通過系統(tǒng)仿真,分析了控制效果。對(duì)本系統(tǒng)的安全性、可靠性和穩(wěn)定性做了分析,將本系統(tǒng)與現(xiàn)有設(shè)備做了比較,并分析了本系統(tǒng)的技術(shù)創(chuàng)新性。
[Abstract]:Packaging machine is the key to the development of packaging industry . It is developing in the direction of intelligence , automation , high efficiency , multifunction and low consumption .

At present , the bobbin yarn mainly depends on the manual packing , but with the increase of the production automation degree of the cheese yarn , the manual packaging has not met the production requirements , and the automatic packaging machine for the cheese yarn has been researched abroad , but the automatic packaging machine cannot be fully realized , and manual participation is required in several links , and the cost is high .

As a high - speed , intelligent and full - automatic packaging equipment for textile industry , the automatic packaging system of cheese yarn is a large packaging production line which integrates on - line detection , precision machinery and real - time control . It requires coordination and cooperation of all parts , and ensures the reliability and stability of the whole system .

Several key technologies in the automatic packaging system of cheese yarn are studied in the following aspects :

1 . According to the process requirement of cheese packing , the paper determines the process of automatic packaging of cheese yarn , and puts forward the idea of " unified control and sub - module design " . The whole packaging process is controlled by PLC , and the monitoring and report output of the whole packaging process in the control room is realized through the upper WinCC configuration .

2 . The whole scheme of the system is designed , the way of each module is compared from the principle , the simplest and reliable design method is found out , the mechanical structure of each module is designed , the pneumatic system is used to drive the executing mechanism , and the process flow of the packaging process is completed , and the existing equipment is selected .
