【正文】 et the demand for production,the technology content is low, especially, it hardly applies advanced technology suchas photo, magic and puter and so on. Therefore, there is a great gap betweenthe packaging accuracy and stability of the domestic packaging machinery and theoverseas equipment. The thesis emphasizes on researching on the control system of XG24128 ― rotaryfilling machine which integrates washing, filling and spinning caps. The machineryfills the 500ml pet bottle at a speed of 18000BPH, the efficiency of single tip sealinglid can reach 20212200 bottle/hour, and the blunder of filling capability isn39。分析連續(xù)灌裝時灌裝頭位置的確定，對灌裝速度進行初 步 分配，并對其換向機構(gòu)進行研究。在研究 XG24128 型灌裝機整體結(jié)構(gòu)的基礎(chǔ)上分析其灌裝的工藝流程，并根據(jù)設(shè)計要求確定灌裝機控制系統(tǒng)的整體方案。 本論文對集清洗、灌裝、加蓋三合一體的旋轉(zhuǎn)型灌裝機一 XG24128 進行控制系統(tǒng)研究，使其對 500ml PET 瓶灌裝速度可達 18000BPH 以上，單個封蓋頭的工作效率可達20212200 瓶 /小時，灌裝容量誤差不大于 3%。江蘇大學本科畢業(yè)設(shè)計 I 繼 續(xù) 教 育 學 院 C o l l e g e O f C o n t i n u i n g E d u c a t i o n Of J i a n g s u U n i v e r s i t y 本 科 畢 業(yè) 論 文 基于 PLC 的旋轉(zhuǎn)灌裝機控制系統(tǒng)設(shè)計 學生學號： 學生姓名： 專業(yè)班級： 指導教師姓名： 指導教師職稱： 年 月 江蘇大學本科畢業(yè)設(shè)計 II 基于 PLC 的旋轉(zhuǎn)灌裝機控制系統(tǒng)設(shè)計 專業(yè)班級 ： 學生姓名： 指導教師： 教師職稱： 摘 要 食品機械是專為食品工業(yè)服務(wù)的，包裝機械大約有 70%是為食品包裝服務(wù)的，特別是近年來飲料工業(yè)迅速發(fā)展，使得液體灌裝設(shè)備的需求大量增長。在高速灌裝下能夠?qū)崿F(xiàn)高的灌裝 精度和運行穩(wěn)定性，自動生產(chǎn)可以實現(xiàn)無瓶不灌裝和無瓶不加蓋。 其次，明確控制系統(tǒng)的硬件配置。 最后，在硬件配置的基礎(chǔ)上，對 XG24128 型灌裝機進行控制系統(tǒng)的軟件設(shè)計。t morethan 3%o, so that it can maintain high accuracy and stability at high speed, moreover,the automatic production can reach the goal ― no bottles no filling, no , the thesis also research the key technology of XG24128 that the fillingsection uses one servo pump to control two tips filling fluid in order to improve thefilling speed and continuous filling. Firstly, this article designs the program of control system. On the basis ofresearching the whole structure of XG24128, it analyses the process flow of thefilling and determines the whole program of the control system of filling machineaccording to the demand of design. Secondly, this article defines the hardware collocation of control system. Itdetermines the type and correlation module of PLC, defines the I/O in light of theprocess requirements and equipment status of filling machinery, and selects andarranges such electrical sections as servo and feeler search. Furthermore, the article researches the key technology of XG24128 that thefilling section uses one servo pump to control two tips tilling fluid in order to improvethe filling speed and continuous filling, analyses how to locate the tips filling fluidduring the continuous filling, distributes the speed of filling, and researching thereverse mechanism. Finally, the paper designs software of control system of XG24128 filling machineon basis of hardware collocation. On basis of analyzing control procedure it draws uprelevant programs and system software with a view to achieving the filling designing software it tries to design HMI of the filling machine.
