和利時(shí)公司PLC事業(yè)部技術(shù)人員對該類型包裝機(jī)運(yùn)行環(huán)境進(jìn)行了現(xiàn)場考察和反復(fù)研究，充分考慮到了現(xiàn)場環(huán)境的不同地域特性（俄羅斯、廣州等），在可靠性、穩(wěn)定性等方面做了大量工作，提出了基于HOLLiAS-LEC G3小型一體化PLC的控制系統(tǒng)。實(shí)際運(yùn)行效果表明，基于G3系列PLC的控制系統(tǒng)達(dá)到了預(yù)期效果，大大提高了設(shè)備的自動(dòng)化水平。    DXD全自動(dòng)包裝機(jī)要求加料、制袋、充填、封口、剪切、撕口等工序全自動(dòng)完成，包裝速度、制袋長度可以調(diào)整。采用HOLLiAS－LEC G3 PLC控制的DXD全自動(dòng)包裝機(jī)是集機(jī)電一體化、光電檢測、步進(jìn)電機(jī)自動(dòng)跟蹤糾偏等功能于一體的多用途自動(dòng)包裝機(jī)，該包裝機(jī)具有電眼跟蹤、PLC控制、無級變速糾偏等功能，計(jì)量，符合行業(yè)標(biāo)準(zhǔn)，并且具有性能穩(wěn)定、操作維護(hù)方便、效率高等特點(diǎn)，保證了包裝袋的長度穩(wěn)定，圖形美觀。   根據(jù)工藝要求，DXD全自動(dòng)包裝機(jī)采用PLC進(jìn)行自動(dòng)控制，包含兩個(gè)關(guān)鍵的步進(jìn)電機(jī)的協(xié)調(diào)運(yùn)行。選用1塊24點(diǎn)CPU模塊LM3106做為整個(gè)控制系統(tǒng)的核心部分， LM3106不僅可以處理普通的DI、DO、AI、AO點(diǎn)，還包含三路高速脈沖計(jì)數(shù)輸入和兩路高速脈沖輸出，其輸出頻率大可達(dá)20KHz。選用深圳人機(jī)電子有限公司的5.7" 藍(lán)色 STN 液晶觸摸屏MT506L作為人機(jī)界面。 3系統(tǒng)設(shè)計(jì)    采用PLC控制的DXD全自動(dòng)包裝機(jī)可以實(shí)現(xiàn)自動(dòng)制袋、自動(dòng)上料、自動(dòng)計(jì)量、自動(dòng)封裝等多項(xiàng)功能，并可對生產(chǎn)過程進(jìn)行實(shí)時(shí)監(jiān)控，完成自動(dòng)診斷、自動(dòng)報(bào)警和數(shù)據(jù)上傳等功能。根據(jù)工藝要求，DXD全自動(dòng)包裝機(jī)的控制系統(tǒng)由人機(jī)界面操作及顯示系統(tǒng)、制袋控制系統(tǒng)、送料計(jì)量控制系統(tǒng)、封裝及剪切控制系統(tǒng)組成。 DXD全自動(dòng)包裝機(jī)的輸入、輸出信號(hào)參見表1。

人機(jī)界面操作及顯示系統(tǒng)如圖1和圖2所示。根據(jù)用戶要求，設(shè)定并顯示包裝容量、制袋長度、每分鐘的包裝速度，系統(tǒng)可顯示出實(shí)際產(chǎn)量（袋數(shù)）和準(zhǔn)確計(jì)量數(shù)（填充量），能夠?qū)τ?jì)量數(shù)手動(dòng)清零，具有正常的啟動(dòng)、停止及點(diǎn)動(dòng)按鈕。設(shè)置畫面帶有權(quán)限保護(hù)，能夠方便調(diào)用光電眼控制及其它輔助控制系統(tǒng)選擇開關(guān)和多料混裝選擇開關(guān)。


下面對DXD全自動(dòng)包裝機(jī)的各控制部分做一簡單說明。    制袋控制系統(tǒng)：制袋過程的啟停有兩種控制方式，即機(jī)側(cè)按鈕和人機(jī)界面操作。無論采用哪種方式，當(dāng)操作者按下啟動(dòng)按鈕時(shí)，拉袋電機(jī)根據(jù)觸摸屏設(shè)定的各種參數(shù)工作，步進(jìn)電機(jī)進(jìn)給，PLC實(shí)時(shí)檢測步進(jìn)電機(jī)的進(jìn)給量。當(dāng)達(dá)到設(shè)定范圍時(shí)，開始判斷拉袋到位傳感器，傳感器信號(hào)為ON時(shí)，拉袋到位，步進(jìn)電機(jī)進(jìn)給停止，計(jì)數(shù)加1。在整個(gè)制袋過程中，觸摸屏實(shí)時(shí)跟蹤、顯示各個(gè)數(shù)據(jù)變化，一旦有故障（如電機(jī)堵轉(zhuǎn)等）或是不合理的數(shù)據(jù)出現(xiàn)，整個(gè)機(jī)器就會(huì)停止，并強(qiáng)行在觸摸屏上顯示并報(bào)警，同時(shí)向上位機(jī)傳送故障內(nèi)容。參數(shù)設(shè)定參見表2。    送料計(jì)量控制系統(tǒng)：送料計(jì)量啟動(dòng)信號(hào)為ON時(shí)，送料開始，送料用伺服電機(jī)根據(jù)觸摸屏設(shè)定的參數(shù)工作。PLC實(shí)時(shí)檢測填充量，伺服電機(jī)根據(jù)計(jì)量值的不同完成加速填充、均速填充、微量填充，填充結(jié)束進(jìn)給到位。在全部的送料過程中，觸摸屏實(shí)時(shí)跟蹤、顯示各個(gè)數(shù)據(jù)變化，一旦有故障（如電機(jī)堵轉(zhuǎn)等）或是不合理的數(shù)據(jù)出現(xiàn)，整個(gè)機(jī)器就會(huì)停止，并強(qiáng)行在觸摸屏上顯示并報(bào)警，同時(shí)向上位機(jī)傳送故障內(nèi)容。參數(shù)設(shè)定參見表2。    封裝及剪切控制系統(tǒng)：為了保證機(jī)器及人員的安全，首先判斷封裝及剪切數(shù)據(jù)的合理性。若數(shù)據(jù)不正確，包裝機(jī)處于保護(hù)狀態(tài)，并在觸摸屏上顯示警告內(nèi)容。若數(shù)據(jù)正確，PLC根據(jù)實(shí)時(shí)采集到的數(shù)據(jù)進(jìn)行計(jì)算，每袋在進(jìn)料結(jié)束后輸出封裝。during the manufacture of this product, so that it can not only remain between the fibers, but also adhere and wrap the fibers. When the paper sheet is heated and dried by the drying part of the paper machine, the hydrophobic compound remaining in the fiber gate and the high molecular polymer adhering to the fiber will form an extremely thin and highly flexible mesh layer with the fiber, so that the fluffy paper sheet can maintain its original strength. 1 experimental part 1.1 raw materials 817 and Jietong 160 are produced by Shanghai Baoshan synthetic detergent factory. Fatty acids, alkylphenol polyoxyethylene ether (PAE), liquid alkali (30%) and other reagents are industrial grade. 1.2 experimental method (1) determination of proportioning and process route orthogonal test method is used to determine the proportioning, process parameters and technical route of each component in the expansion agent. (2) physical and chemical properties were measured, and physical and chemical properties such as solid content, pH value, foaming power and water solubility were measured. (3) Determination of the optimal dosage of expansion agent through the papermaking test of adding different amounts of expansion agent into pulp in the laboratory, the optimal dosage of expansion agent in different pulp is determined by the quality of equal volume finished dry paper and the tensile strength of paper sheet. (4) Establishment of application method of expansion agent through the application test in the paper mill, the application method of expansion agent is established. (5) The efficacy test of expansion agent through the application test in the laboratory and paper mill, the quality of finished sanitary roll paper with equal diameter and equal height with and without expansion agent is compared to investigate the expansion efficacy of expansion agent. 2 results and discussion 2.1 expansion agent formula the best ratio of each component in pulp expansion agent is determined through orthogonal test. The results are shown in Table 1.According to the composition and content in the table, the main components of this product are anionic and non-ionic surfactants. Because the repulsion between anionic surfactant and fiber increases the distance between fibers and weakens the hydrogen bond between fibers, the volume of pulp suspension increases. Nonionic surfactants, such as alkylphenol polyoxyethylene ether (PAE), can make the fiber feel greasy and soft. High polymer PPA can increase the strength of the paper to offset the decrease of the paper strength due to the increase of the distance between fibers. A small amount of defoamer can be added to the extruding agent in order to prevent the foaming of the extruder from mixing with the pulp. 2.2 production process of expansion agent after repeated experiments and trial production, the production process of expansion agent is determined, as shown in Figure 1.



During production, put the fatty acid in the reactor, heat it appropriately, add liquid alkali for neutralization, and adjust the pH to 6.5 ~ 7.0. Then add Jietong 160, 817, PPA
