1、<p><b>  譯文</b></p><p>  論藥品包裝機(jī)械的概念設(shè)計(jì)</p><p>  近年來(lái),由于我國(guó)經(jīng)濟(jì)形勢(shì)的持續(xù)高漲和國(guó)家對(duì)制藥行業(yè)強(qiáng)制性推行GMP(藥品生產(chǎn)質(zhì)量規(guī)范)認(rèn)證制度,藥品包裝機(jī)械取得了長(zhǎng)足的進(jìn)步。新產(chǎn)品日益增多,技術(shù)水平有了很大的改進(jìn)。但與國(guó)際水平相比還存在著很大的差距,近60%的產(chǎn)品達(dá)不到發(fā)達(dá)國(guó)家上世紀(jì)80年代的水平,先進(jìn)大型

2、的設(shè)備主要依賴進(jìn)口。我國(guó)藥品包裝機(jī)械的低技術(shù)水平在很大程度上是由我國(guó)企業(yè)設(shè)計(jì)人員低水平設(shè)計(jì)引起的。</p><p>  一、我國(guó)藥品包裝機(jī)械現(xiàn)狀分析</p><p>  我國(guó)藥品包裝機(jī)械與國(guó)際先進(jìn)水平相比尚有較大的差距.國(guó)產(chǎn)藥品包裝機(jī)械設(shè)計(jì)上主要存在以下幾點(diǎn)不足:</p><p>  1) 機(jī)械性能落后,國(guó)產(chǎn)藥品包裝機(jī)械大多精度低、速度慢、平穩(wěn)性差。包裝機(jī)械運(yùn)轉(zhuǎn)過(guò)程

3、包含大量復(fù)雜的間歇式運(yùn)動(dòng),主要由凸輪、連桿來(lái)實(shí)現(xiàn)。然而許多設(shè)計(jì)人員不會(huì)根據(jù)工作循環(huán)圖和精度要求獨(dú)立設(shè)計(jì)計(jì)算凸輪連桿機(jī)構(gòu)的運(yùn)動(dòng)學(xué)和動(dòng)力學(xué)參數(shù),只是簡(jiǎn)單的把國(guó)外樣機(jī)的凸輪連桿零件拆卸下來(lái)進(jìn)行逐點(diǎn)測(cè)繪,造成執(zhí)行機(jī)構(gòu)誤差很大。國(guó)產(chǎn)藥品包裝機(jī)械大多運(yùn)行速度較低,如鋁塑泡罩包裝機(jī)的沖裁頻率一般為100~300個(gè)/min,全自動(dòng)藥盒包裝機(jī)的裝盒速度50~200盒/min,而國(guó)際上先進(jìn)的鋁塑泡罩包裝機(jī)的沖裁頻率能夠達(dá)到600個(gè)/min,全自動(dòng)藥盒包裝機(jī)

4、的裝盒速度能夠達(dá)到600~ 800盒/min。國(guó)產(chǎn)藥品包裝機(jī)械不僅運(yùn)行速度慢,而且還伴有較大的噪音。</p><p>  2) 控制水平落后。國(guó)產(chǎn)藥品包裝機(jī)械大多控制水平低、自動(dòng)性差、故障率高。國(guó)產(chǎn)藥品包裝機(jī)械(主要指盒裝和灌裝機(jī)械)大多采用PLC作現(xiàn)場(chǎng)控制,而國(guó)外先進(jìn)的藥品包裝機(jī)械大多由計(jì)算機(jī)系統(tǒng)實(shí)現(xiàn)監(jiān)控,控制水平相對(duì)落后。大多數(shù)國(guó)產(chǎn)藥品包裝機(jī)械自動(dòng)性較差。一是普遍采用單機(jī)生產(chǎn)模式,全自動(dòng)生產(chǎn)線少。二是做不到全

5、自動(dòng)運(yùn)轉(zhuǎn),需要人工加料,手動(dòng)裝箱。如一些紙盒包裝機(jī)中,藥板、說(shuō)明書(shū)紙頁(yè)、紙盒都需要手動(dòng)加料,且需專(zhuān)人隨時(shí)注意說(shuō)明書(shū)、藥板、紙盒是否已經(jīng)用完,以免造成機(jī)器空轉(zhuǎn)或造成缺說(shuō)明書(shū)、藥板、藥盒現(xiàn)象的發(fā)生。另外,國(guó)產(chǎn)藥品包裝機(jī)械故障率較高??刂圃骷?如繼電器、電磁閥、接觸器、斷路器等)等經(jīng)常容易損壞,死機(jī)故障也時(shí)有發(fā)生。</p><p>  3)功能單一、可擴(kuò)展性差。藥品包裝機(jī)械是針對(duì)特定的包裝形式設(shè)計(jì)的。一般在規(guī)定的規(guī)格

6、范圍內(nèi)可調(diào)。而我國(guó)許多藥品包裝機(jī)械在設(shè)計(jì)時(shí)考慮不充分,沒(méi)有為進(jìn)一步的改造留出足夠的空間,致使設(shè)計(jì)的機(jī)械只能適應(yīng)于幾種簡(jiǎn)單的模板,不適應(yīng)包裝材料或模板尺寸的變化,即使適應(yīng)生產(chǎn)的包裝成品質(zhì)量也不佳。</p><p>  4)綜合考慮不足,資源沒(méi)有充分利用。我國(guó)藥品包裝機(jī)械設(shè)計(jì)存在著混亂現(xiàn)象,許多機(jī)械設(shè)計(jì)人員對(duì)電機(jī)拖動(dòng)同步技術(shù)、伺服傳動(dòng)技術(shù)不了解,可用簡(jiǎn)單的電器設(shè)備解決的問(wèn)題卻用復(fù)雜的機(jī)械裝置來(lái)實(shí)現(xiàn),有的雖然采用了同步

7、電機(jī)等裝置來(lái)控制機(jī)構(gòu)運(yùn)行,但選取不當(dāng)。這些情況不僅造成了資源的極大浪費(fèi),而且使設(shè)計(jì)的機(jī)械的性能低下。</p><p>  5)造型死板。我國(guó)的藥品包裝機(jī)械設(shè)計(jì)時(shí)很少考慮機(jī)械的造型,很多廠家生產(chǎn)的機(jī)械造型不美觀,甚至沒(méi)有造型,給人感覺(jué)僵硬、死板、沒(méi)有活力。一些藥盒包裝機(jī)中,螺釘螺母都安裝在機(jī)器的外面板上,而一些潤(rùn)滑用的油杯和油嘴也隨處可見(jiàn),加油時(shí)容易使機(jī)器到處沾滿油污,給人印象粗糙,不美觀。</p>

8、<p>  二、藥品包裝機(jī)械概念設(shè)計(jì)的內(nèi)容</p><p>  人們經(jīng)過(guò)多年的研究,將概念設(shè)計(jì)定義為:“在確定了任務(wù)后,通過(guò)抽象化擬定功能結(jié)構(gòu),尋求適當(dāng)?shù)淖饔迷砑捌浣M合等,確定出基本求解途徑,得出求解方案。這一部分設(shè)計(jì)工作叫做概念設(shè)計(jì)”概念設(shè)計(jì)指明確設(shè)計(jì)目的和現(xiàn)有條件后,設(shè)計(jì)者搜索多方面的知識(shí),分析提煉后生成框架式的廣泛意義上的解。藥品包裝機(jī)械的概念設(shè)計(jì)要求根據(jù)產(chǎn)品生命周期各個(gè)階段,進(jìn)行產(chǎn)品功能創(chuàng)造、

9、功能分解以及功能和子功能的結(jié)構(gòu)設(shè)計(jì),進(jìn)行滿足功能和結(jié)構(gòu)要求的工作原理求解和進(jìn)行實(shí)現(xiàn)功能結(jié)構(gòu)的工作原理載體方案的構(gòu)思和系統(tǒng)化設(shè)計(jì)概念設(shè)計(jì)的過(guò)程是一個(gè)求解實(shí)現(xiàn)功能的、滿足各種技術(shù)和經(jīng)濟(jì)指標(biāo)的、可能存在的各種方案并最終確定綜合最優(yōu)方案的過(guò)程。概念設(shè)計(jì)的作用主要體現(xiàn)在產(chǎn)品設(shè)計(jì)的早期階段。總設(shè)計(jì)師根據(jù)產(chǎn)品功能的需求而萌發(fā)出來(lái)的原始構(gòu)思和沖動(dòng)形成產(chǎn)品的主體框架,及它應(yīng)包括的各主要模塊和組件,以完成整體布局和外型初步設(shè)計(jì)。然后進(jìn)行評(píng)估和優(yōu)化,確定整體

10、設(shè)計(jì)方案。再由各部分設(shè)計(jì)人員把總設(shè)計(jì)師的設(shè)計(jì)思想落實(shí)到具體設(shè)計(jì)中去,實(shí)現(xiàn)細(xì)節(jié)設(shè)計(jì)。實(shí)施藥品包裝機(jī)械的概念設(shè)計(jì)首先要求設(shè)計(jì)人員加強(qiáng)對(duì)藥品包裝的認(rèn)識(shí),深化理解藥品包裝的內(nèi)涵,引進(jìn)現(xiàn)代包裝理念,積極與國(guó)際接軌?,F(xiàn)代包裝不僅是</p><p>  1)明確設(shè)計(jì)任務(wù),做好可行性分析。設(shè)計(jì)者在進(jìn)行設(shè)計(jì)工作初始階段時(shí)應(yīng)充分考慮產(chǎn)品的可行性。一方面是市場(chǎng)的考慮,包括產(chǎn)品銷(xiāo)售、產(chǎn)品原料、制造費(fèi)用的考慮;另一方面是產(chǎn)品加工的考慮,包

11、括現(xiàn)有加工能力、加工工藝、加工性能及周邊配套行業(yè)的考慮。周邊配套環(huán)境的考慮主要指當(dāng)?shù)仄髽I(yè)加工能力、加工水平、熱處理工藝及基礎(chǔ)設(shè)施的建設(shè)等。</p><p>  2)功能設(shè)計(jì)。我國(guó)大多數(shù)藥品包裝機(jī)械是對(duì)國(guó)外同類(lèi)機(jī)型的仿制。但由于我國(guó)存在的特殊國(guó)情,須對(duì)產(chǎn)品進(jìn)行適當(dāng)?shù)母脑?,以滿足我國(guó)的要求。而不是一味的照抄照搬。設(shè)計(jì)的機(jī)械除需要滿足盒裝、灌裝功能外,我們還須考慮包裝機(jī)械的附加功能,如包裝盒中應(yīng)加入量杯、藥勺等工具,以

12、方便用戶使用。在機(jī)種的開(kāi)發(fā)方面可以設(shè)計(jì)較為先進(jìn)的機(jī)械,如無(wú)菌包裝機(jī)械、保鮮包裝機(jī)械等。還可以開(kāi)發(fā)藥品包裝前處理成套設(shè)備和后處理配套設(shè)備。 </p><p>  3)功能分解。藥品包裝機(jī)械屬于機(jī)電一體化產(chǎn)品,設(shè)計(jì)時(shí)應(yīng)全面考慮各功能。一般而言,藥品包裝機(jī)械功能大致可分為機(jī)構(gòu)運(yùn)動(dòng)、監(jiān)測(cè)傳感、信息處理及控制功能3大部分。機(jī)構(gòu)運(yùn)動(dòng)功能按不同機(jī)種又可細(xì)分,如鋁塑泡罩包裝機(jī)可分為成型、熱封、壓痕、沖裁4大功能,而紙盒包裝機(jī)

13、械可分為折紙、下紙、藥板推送、紙盒打開(kāi)、紙盒傳輸、折舌、插舌、壓平和打批號(hào)等功能。在設(shè)計(jì)過(guò)程中還要考慮機(jī)械潤(rùn)滑、機(jī)械安全運(yùn)行、包裝衛(wèi)生等功能。這要求設(shè)計(jì)人員充分考慮檢測(cè)技術(shù),光、機(jī)、電一體化技術(shù)、計(jì)算機(jī)技術(shù).氣動(dòng)技術(shù)、物流技術(shù)之間的交叉聯(lián)系。 </p><p>  4)機(jī)構(gòu)設(shè)計(jì)。為實(shí)現(xiàn)預(yù)定的功能,我們需要使用不同的機(jī)構(gòu)。這一過(guò)程中需綜合考慮整機(jī)的各個(gè)部分,使設(shè)計(jì)的產(chǎn)品在滿足使用要求的同時(shí),結(jié)構(gòu)簡(jiǎn)單、實(shí)用。藥

14、品包裝機(jī)械機(jī)構(gòu)設(shè)計(jì)時(shí),應(yīng)選擇和組合適當(dāng)?shù)臋C(jī)構(gòu)運(yùn)動(dòng)原理,充分考慮實(shí)現(xiàn)特定運(yùn)動(dòng)所需機(jī)構(gòu),如凸輪機(jī)構(gòu),連桿機(jī)構(gòu),凸輪連桿機(jī)構(gòu)。同時(shí)還應(yīng)運(yùn)用分離傳動(dòng)技術(shù),綜合考慮傳動(dòng)軸(如花鍵軸和階梯軸等)和傳動(dòng)系統(tǒng)的設(shè)計(jì)問(wèn)題。設(shè)計(jì)過(guò)程中應(yīng)盡量減少不確定性因素造成的影響,使機(jī)構(gòu)運(yùn)行平穩(wěn)。設(shè)計(jì)時(shí)還應(yīng)對(duì)機(jī)械進(jìn)行動(dòng)力學(xué)分析,以提升機(jī)械運(yùn)行速度和平穩(wěn)性。另外還應(yīng)考慮包裝機(jī)械的多樣、可調(diào)、容錯(cuò)、可擴(kuò)展、平穩(wěn)性以及美觀化,追求機(jī)械輕巧但穩(wěn)定。設(shè)計(jì)過(guò)程可參考各類(lèi)包裝機(jī)械設(shè)計(jì)

15、的長(zhǎng)處,同時(shí)借鑒別的機(jī)械(如塑料機(jī)械、印刷機(jī)械)的優(yōu)點(diǎn)。除進(jìn)行機(jī)構(gòu)設(shè)計(jì)外.還應(yīng)考慮各功能另外的實(shí)現(xiàn)途徑,如真空、電器控制等,以期最優(yōu)組合該產(chǎn)品。 </p><p>  5)系統(tǒng)控制方案的設(shè)計(jì)。藥品包裝機(jī)械中一個(gè)很重要的部分就是對(duì)各機(jī)構(gòu)實(shí)時(shí)檢測(cè)補(bǔ)償,以保證設(shè)備運(yùn)行順暢?,F(xiàn)在很多機(jī)械產(chǎn)品選用了大量的光電開(kāi)關(guān)作為檢測(cè)元件,有的機(jī)械上還裝備有諸如微機(jī)檢測(cè)泡罩系統(tǒng)之類(lèi)的系統(tǒng)。這都需要精心設(shè)計(jì)和整個(gè)控制系統(tǒng)連為一體。&

16、lt;/p><p><b>  三、結(jié)語(yǔ)</b></p><p>  將概念設(shè)計(jì)的思想融入藥品包裝機(jī)械的設(shè)計(jì)可以減少設(shè)計(jì)失誤,縮短設(shè)計(jì)周期,加快產(chǎn)品的開(kāi)發(fā),使設(shè)計(jì)的產(chǎn)品更合理、更具有親和力、更適合人機(jī)工程。同時(shí)它也是降低成本和提高企業(yè)競(jìng)爭(zhēng)力的主要手段。為了改善藥品包裝機(jī)械設(shè)計(jì)落后、缺乏競(jìng)爭(zhēng)力的被動(dòng)局面,以適應(yīng)“后GMP時(shí)代”帶來(lái)的挑戰(zhàn),設(shè)計(jì)人員必須重視產(chǎn)品概念設(shè)計(jì),深化理
