【摘要】：現(xiàn)代感應(yīng)電爐的爐襯由高溫耐火材料構(gòu)成。對于爐襯耐火材料的配料包裝,國內(nèi)主要采用人工配料方法,生產(chǎn)效率低、現(xiàn)場粉塵多;國外主要采用自動配料方法,設(shè)備成本高,維修不便。因此,本課題設(shè)計(jì)了一套集稱重、運(yùn)輸、攪拌、包裝于一體的全自動配料包裝系統(tǒng),能夠提高生產(chǎn)效率,同時降低勞動成本。首先,課題分析了自動配料包裝系統(tǒng)的機(jī)械結(jié)構(gòu)和工藝流程,根據(jù)設(shè)計(jì)要求制定了控制方案,選用工控平板電腦作為上位機(jī),西門子PLC作為系統(tǒng)核心控制器。上位機(jī)可以實(shí)現(xiàn)配料參數(shù)的設(shè)置以及對系統(tǒng)運(yùn)行情況的監(jiān)控;PLC可以通過數(shù)字量模塊、工業(yè)以太網(wǎng)以及PROFIBUS-DP通信實(shí)現(xiàn)對現(xiàn)場設(shè)備的控制。根據(jù)控制方案對系統(tǒng)硬件進(jìn)行設(shè)計(jì),主要包括設(shè)備選型、圖紙繪制、電氣連接以及參數(shù)設(shè)置。然后,針對系統(tǒng)關(guān)鍵環(huán)節(jié)—稱重單元進(jìn)行數(shù)學(xué)模型搭建,基于迭代學(xué)習(xí)控制算法在MATLAB軟件上對稱重單元進(jìn)行仿真設(shè)計(jì),并分析仿真結(jié)果。在上述工作基礎(chǔ)上,對系統(tǒng)軟件進(jìn)行設(shè)計(jì),主要包括PLC硬件組態(tài)、PLC控制程序編寫以及上位機(jī)Win CC組態(tài)。最終,課題完成了系統(tǒng)的搭建,通過多次調(diào)試運(yùn)行,實(shí)現(xiàn)了配料包裝的全自動化生產(chǎn),配料精度以及配料周期也達(dá)到了工藝要求。
[Abstract]:The lining of a modern induction furnace is made of high-temperature refractories. For the burdening packing of refractory material for furnace lining, the method of artificial proportioning is mainly used in our country, the production efficiency is low, and the field dust is much; the foreign countries mainly adopt automatic proportioning method, the cost of equipment is high, and the maintenance is inconvenient. Therefore, this paper designs a set of automatic proportioning packaging system which integrates weighing, transportation, agitation and packing, which can improve the production efficiency and reduce the labor cost at the same time. Firstly, the paper analyzes the mechanical structure and technological process of the automatic batching packaging system. According to the design requirements, the control scheme is established. The industrial control tablet computer is selected as the host computer and Siemens PLC as the core controller of the system. The upper computer can realize the setting of the proportioning parameters and the monitoring of the system operation. The PLC can realize the control of the field equipment through the digital module, industrial Ethernet and PROFIBUS-DP communication. The hardware of the system is designed according to the control scheme, including equipment selection, drawing, electrical connection and parameter setting. Then, aiming at the key link of the system-weighing unit, the mathematical model is built, and the symmetrical weight unit is simulated on MATLAB software based on iterative learning control algorithm, and the simulation results are analyzed. On the basis of the above work, the software of the system is designed, including the programming of the PLC hardware configuration and the configuration of the upper computer Win CC. Finally, the project completed the system construction, through many times debugging and running, achieved the full automatic production of batching packaging, the batching precision and batching cycle also reached the technological requirements.
