25、展提供了有力的保障。目前，我國已成為世界包裝機械工業(yè)生產(chǎn)和消費大國之一。 當(dāng)前我國食品和包裝機械的一個突出問題是新產(chǎn)品開發(fā)周期長、模仿多、創(chuàng)新少，這不僅與設(shè)計人員的知識水平有關(guān)，也和相關(guān)行業(yè)的發(fā)展有關(guān)。 國際先進的作法是運用仿真技術(shù)，由計算機自動合成三維模型，將過去曾經(jīng)發(fā)生過的生產(chǎn)線故障數(shù)據(jù)輸入計算機，即可演示實際工況，在用戶面前根據(jù)需要進行修改，最終完善。包裝機械作為一種產(chǎn)品，它的含義不僅僅是產(chǎn)品本身的物質(zhì)意義，而是包括形式產(chǎn)

26、品、隱形產(chǎn)品及延伸產(chǎn)品3層含義。形式產(chǎn)品是指包裝機本身的具體形態(tài)和基本功能；隱形產(chǎn)品是指包裝機給用戶提供的實際效用；延伸產(chǎn)品是指包裝機的質(zhì)量保證、使用指導(dǎo)和售后服務(wù) 等。所以包裝機的設(shè)計應(yīng)該包括：市場調(diào)研、原理圖設(shè)計、結(jié)構(gòu)設(shè)計、施工圖設(shè)計、使用說明書編寫及售后服務(wù)預(yù)案等。</p><p>　　新型包裝機械往往是機、電、氣一體化的設(shè)備。充分利用信息產(chǎn)品的最新成果，采用氣動執(zhí)行機構(gòu)、伺服電機驅(qū)動等分離傳動技術(shù)， 可

27、使整機的傳動鏈大大縮短，結(jié)構(gòu)大為簡化，工作精度和速度大大提高。其中的關(guān)鍵技術(shù)之一是采用了多電機拖動的同步控制技術(shù)。其實 掌握這種技術(shù)并不很難，只是一些設(shè)計人員不了解包裝機械的這一發(fā)展趨勢。如果說以前我國包裝機械設(shè)計是仿制、學(xué)習(xí)階段，那么現(xiàn)在 我們應(yīng)該有創(chuàng)新設(shè)計的意識。 “十五”期間，我國包裝機械工業(yè)發(fā)展迅速，近幾年進口的設(shè)備都是國內(nèi)不能制造或者制造水平相差甚遠的，從進口可以看出我們的差距所在。 食品安全問題舉國關(guān)注。“十一五”期

28、間應(yīng)提高食品安全領(lǐng)域的科技和裝備水平，研制快速、準確鑒定食品中危害因子的技術(shù)和裝備，進一步研發(fā)病原微生物的抗性、病原的控制等預(yù)防技術(shù)及儲藏技術(shù)和裝備。 食品和包裝機械形成行業(yè)已20年，相對于食品包裝，還是一個新行業(yè)。這20年又是世界技術(shù)發(fā)展最快的時期，新技術(shù)不斷在行業(yè)上應(yīng)用，而國內(nèi)行業(yè)的基礎(chǔ)薄弱，技術(shù)及科研力量不足，其發(fā)展相對滯后，在某種程度上拖了食品和包裝工業(yè)的后腿?？傮w發(fā)展雖然較快，但食品包裝機械工業(yè)發(fā)展更快。</p>

29、<p>　　“十一五”的目標是要縮小這個空間，為食品工業(yè)趕上世界先進水平，為使包裝大國向包裝強國邁進，提供先進的技術(shù)裝備，讓進口設(shè)備在國內(nèi)市場上只起到拾遺補缺的作用。這就要求國內(nèi)食品和包裝機械的年發(fā)展速度超過18%，新產(chǎn)品產(chǎn)值率達到25%。 國際上包裝和食品機械的發(fā)展是以大客戶的要求為目標，帶動相關(guān)機械的發(fā)展。大客戶的要求主要體現(xiàn)在以下方面： 一是對生產(chǎn)效率要求越高越好。這樣可以降低產(chǎn)品的成本，滿足交貨期。高速包裝機要求與前

30、道工序要有相關(guān)銜接，不需搬運環(huán)節(jié)，包括控制銜接，整個生產(chǎn)線按生產(chǎn)及包裝工序排列要做到倒序啟動，順序停機。如冷灌裝生產(chǎn)線從塑料原料自動上線到飲料灌裝、大包裝碼垛全部自動在封閉車間內(nèi)進行。 二是可適應(yīng)產(chǎn)品的更新變化。包裝機械要具有很高的柔性和靈活性，生產(chǎn)線允許在一定的尺寸范圍內(nèi)包裝物大小可以變化。因為產(chǎn)品的生命周期遠短于設(shè)備使用壽命，變更產(chǎn)品及包裝不至于更換昂貴的包裝生產(chǎn)線。 三是設(shè)備常見故障迅速排除。解決方案預(yù)先輸入電腦，當(dāng)設(shè)備出現(xiàn)常見的

31、故障時可以自行診斷，亦可實行遠程診斷并排除故障。 四是要求具有自動識別功能。一方面可以自動識別包裝材料的厚度、硬度、反彈力等，通過電腦反饋到機械</p><p>　　現(xiàn)代包裝機的設(shè)計過程應(yīng)該包括：市場調(diào)研、用戶需求分析、包裝機功能的確定、可行性論證、制定設(shè)計方案、用戶效益分析、方案 的可行性論證、原理圖設(shè)計、結(jié)構(gòu)設(shè)計、施工圖設(shè)計、樣機制作(虛擬制造)、技術(shù)驗證和施工圖修改、制定售后服務(wù)預(yù)案及遠程診斷方 案、改進設(shè)

32、計、系列化設(shè)計等。 市場調(diào)研是一切包裝機設(shè)計的基礎(chǔ)工作。沒有市場調(diào)研，我們所做的所有設(shè)計工作都可能等于零。市場調(diào)研，可以根據(jù)政策導(dǎo)向、行 業(yè)供求信息、專家分析、行業(yè)展會、技術(shù)交流會等線索，找到用戶的需求信息，并加以整理分析后，確定包裝機應(yīng)該完成的功能。在原理方案設(shè)計過程中，首先要充分了解相關(guān)的信息產(chǎn)品、電子產(chǎn)品的功能，了解氣動元件的性能，并用以簡化機械傳動系統(tǒng)，還可 采用多電機拖動來縮短機械傳動鏈。對于必不可少的機械傳動系統(tǒng)，

33、應(yīng)盡量利用現(xiàn)代化設(shè)計手段，在對產(chǎn)品功能分析的基礎(chǔ)上，通過創(chuàng)新 構(gòu)思、系統(tǒng)建模、動力分析、動態(tài)優(yōu)化，從而得到最佳設(shè)計方案。技術(shù)設(shè)計是將原理設(shè)計結(jié)構(gòu)化，確定零部件的數(shù)量、形狀、尺寸、材料等，對主要部件中關(guān)鍵零件進行動力計算、功率計算、強度計算、剛度計算。</p><p>　　總體設(shè)計時，要全面考慮整個包裝機系統(tǒng)的布局、運動協(xié)調(diào)性、造型設(shè)計、人-機環(huán)境以及裝箱運輸?shù)?。模塊化設(shè)計是一種先進的設(shè) 計方法，它的核心思想是將

34、系統(tǒng)根據(jù)功能分為若干模塊，將包裝機中同一功能的單元設(shè)計成具有不同性能、可以互換的模塊，通過模塊的 不同組合，使包裝機多功能化、系列化。采用這種方法的優(yōu)點是：(1)使包裝機更新?lián)Q代速度加快。因為新機型的替代，往往是局部改 進。將先進技術(shù)引進相應(yīng)的模塊，比較容易實現(xiàn)局部改進；(2)縮短設(shè)計周期。當(dāng)用戶提出要求后，只需更換模塊，或設(shè)計制造部分模 塊，即可得到新的機型，滿足用戶需求；(3)降低成本，便于維修；(4)性能穩(wěn)定可靠。因為模塊設(shè)計時，
