【正文】 I 摘 要 隨著工業(yè)自動化水平日益提高，眾多工業(yè)企業(yè)均面臨著傳統(tǒng)生產線的改造和重新設計問題。 PLC（可編程序控制器）是以微處理器為核心的工業(yè)控制裝置，它將傳統(tǒng)的繼電器控制系統(tǒng)與計算機技術結合在一起，近年來在工業(yè)自動控制、機電一體化、改造傳統(tǒng)產業(yè)等方面得到普遍應用。作為通用工業(yè)控制計算機，其實現了工業(yè)控制領域接線邏輯到存儲邏輯的飛躍，在世界工業(yè)控制中發(fā)揮著越來越重要的作用。 在飲料行業(yè)，自動化生產線的生產方式是推廣的最普及的一種生產模式，它促使灌裝的速度 大幅提升，同時也使得灌裝精度更高，給企業(yè)帶來了不可小覷的 生產力。 鑒于此，設計者利用 PLC的功能和特點設計出了一款飲料灌裝生產流水線控制系統(tǒng) 。 本文所涉及的 飲料 灌裝自動化生產線采用 PLC 控制，流量計計量，確保了灌裝的速度和精度。 本文詳細論述了 飲料 灌裝機控制系統(tǒng)的設計步驟，通過對灌裝機系統(tǒng)的充分了解，以行業(yè)現狀為出發(fā)點，結合其他行業(yè)自動控制技術的應用情況，提出了基于 PLC 的 飲料 灌裝機控制系統(tǒng)的基本結構 。 本系統(tǒng)設計中完成了飲料 灌裝機控制系統(tǒng)的硬件的配置和軟件方面的設計， 實現了 飲料 灌裝機控制系統(tǒng)的自動化 。 對勞動生產率的提高，對飲料的質量和產量的提高都具有深遠的意義 。 利用 PLC 控制飲料灌裝生產過程，可有效提高灌裝生產效率，并顯著增加控制系統(tǒng)的可靠性和柔性 。 關鍵詞： 可編程控制器 ； 自動化 ； 灌裝 ； 生產線 II Abstract With the increasing level of industrial automation, many industrial enterprises are faced with the transformation of traditional production line and redesign problem. PLC (programmable logic controller) is a microprocessor as the core of industrial control devices, it will relay the traditional control system bined with puter technology in recent years in industrial automation, mechanical and electrical integration, the transformation of traditional industries such as generally applied. As a generalpurpose industrial control puter, the realization of industrial control wiring logical leap in logic to storage, industrial control in the world is playing an increasingly important role. In beverage industry, automated production line mode of production is to promote the most popular a kind of production mode, it causes the filling speed increases, but make the filling a higher precision, to bring enterprise cannot small gaze of productivity. In view of this, the designers of the use of PLC functions and features designed a beverage filling production line control system. This paper involves the drinks filling automation production line adopts PLC control, flow meter metering, insure the filling speed and precision. This paper describes in detail the control system of the drinks filling machine design steps, a brief introduction of the drinks filling machine control system and base on the selfindustry and the application of the other trade on autocontrol technique, proposed the frame of the control system based on programmable logical controller. This design pletes the drinks production line hardware configuration and software design, to achieve the automation of the carbonated drinks filling machine. Not only improve the labor productivity, but also has farreaching significance of the improvement of quality and yield. PLC control of the use of beverage filling production process, which can effectively improve the production efficiency of filling, and significantly increase the reliability of control systems and flexible. Keywords: Programmable controller； Automation； Filling； Production line 目 錄 摘 要 ........................................................................................................................
