Has become in the mechanical industry one of 10 big professions, regardless of is t

2、he output, in the variety, has all obtained the amazing achievement, packed the industry for our country the fast development to provide the powerful safeguard. At present, our country has become the world packing mechanical industrial production and expends one of great nations.Current our country

3、food and a packing machinery prominent question is the new product development cycle long, imitates much, innovates few, not only this with designs personnel's state-of-art related, also concerns with the correlation profession development. The international advanced method utilizes the simulati

4、on technology, by the computer automatic synthesis three-dimensional model, will pass has occurred production line breakdown data feeds the computer, then will demonstrate the actual operating mode, according to will need to carry on the revision in front of the user, finally will consummate. The pa

5、cking machinery took one product, its meaning is not merely the product itself material significance, but is includes the form product, the stealth product and extends the product 3 meanings. The form product is refers to packaging machine itself the concrete shape and the basic function; The stealt

6、h product is refers to the packaging machine the actual utility which provides to the user; Extends the product is refers to the packaging machine the quality assurance, the use instruction and the post-sale service and so on. Therefore the packaging machine design should include: Market investigati

7、on and study, schematic diagram design, structural design, construction drawing design, instruction for use compilation and post-sale service predetermined plan and so on. The new packing machinery often is machine, the electricity, the gas integration equipment. The full use information product new

8、est achievement, uses air operated separation transmission technologies and so on implementing agency, servo motor-driven, may cause the complete machine the transmission chain to reduce greatly, the structure is greatly the simplification, the work precision and the speed enhances greatly. One of k

9、ey technologies has used the multi-electrical machinery dragging synchronization control technology. Actually grasps this kind of technology not very difficultly, only is some designs the personnel not to understand the packing machinery this trend of development. If beforehand our country packs the

10、 machine design is the imitation, the study stage, then we should have the innovation design consciousness now. “十五” period, our country packs the mechanical industrial development to be rapid, in recent years imports the equipment all is domestic cannot make or the manufacture level is far from, ma

11、y see our disparity from the import to be at. Food security problem whole nation attention. “十一五” period should enhance food security domain the science and technology and the equipment level, the development fast, in accurate appraisal food harms the factor the technology and the equipment, further

12、 researches and develops the pathogenic microorganism resistance, cause of disease prevention technologies and the preserve technology and the equipment and so on control. Food and the packing machinery form the profession already for 20 years, is opposite in food packing, a new profession. This 20

13、years also are the world technological development quickest times, the new technology applies unceasingly in the profession, but the domestic profession foundation is weak, technical and the scientific research lack of strength, its development relative lag, has towed food and the packing industry h

14、ind leg to a certain extent. Although overall development quick, but food packing mechanical industrial development is quicker.the goal is must reduce this space, catches up with the world advanced level for the food industry, for causes the packing great nation to make great strides forward to the

15、packing powerful nation, provides the advanced technical equip, lets import the equipment the role which only plays in the domestic market appropriates lost articles fills a vacancy. This request domestic food and the packing machinery year development speed surpasses 18%, the new product output val

16、ue rate achieves 25%. On the international packing and food machinery development is take the big customer request as the goal, the impetus correlation machinery development. The big customer request mainly manifests in the below aspect: One, is higher well to the production efficiency request. This

17、 may reduce the product the cost, satisfies the date of delivery. The high speed packaging machine request must have the correlation engagement with the first working procedure, does not have to transport the link, including the control engagement, the entire production line must achieve the inverte

18、d order according to the production and the packing working procedure arrangement to start, smooth engine off. If Leng Guanzhuang the production line makes something a matter of political line automatically from the plastic raw material to the drink fills installs, the big packing piles buttress com

19、pletely automatically in seals up in the workshop to carry on. Two, may adapt the product renewal change. The packing machinery must have the very high flexibility and the flexibility, the production line permission the packing material size may change in certain size scope. Because product life cyc

20、le far short in useful life of equipment, change product and packing not as for replacement expensive packing production line. Three is the equipment common breakdown rapid elimination. The solution inputs the computer in advance, when the equipment appears the common breakdown may diagnose voluntar

21、ily, also may implement the long-distance diagnosis to eliminate the breakdown abreast in row. Four, the request has the automatic diagnosis function. On the one hand may automatic diagnosis packing material thickness, degree of hardness, the counter-tension and so on, feed back through the computer

22、 to the manipulator adjusts the movement scope, does not guarantee the resilience. On the other hand, each different product, like shape each different chocolate or the dessert and so on, install to the identical box in, its arrangement is orderly. The production line transmits the product is a diso

23、rder, the available probe head scanning, determined the different shape the material position, feeds back again to the different manipulator, it can accurately unmistakably puts in the goods according to the accurate position and the direction in the tray, moreover, removes the manual control quickl

24、y the vision and finger weariness. Five, may reduce the environmental pollution as far as possible. The reduction including the noise, the dust pollution, and reduces the reject as far as possible, this point especially is important in the food processing process. Food raw material when processing n

25、ot only harvests the main product, like corn processing, product besides corn starch, but also has the corn oil, the salad oil, the margarine, the glucose, the corn protein and the feed, as well as the sewage treatment and so on produces the entire process, is the automation. Does not have the rejec

26、t, not to pollute, other product value has surpassed the corn starch greatly the value.Along with the science and technology development and the market competition aggravating, the customer demand more and more is also high. This kind of demand manifests in following several aspects: One, enhances t

27、he production efficiency, satisfies the date of delivery and reduces the production cost the need, to some products, but also requests the packing machinery and the production machinery links up; Two, is meets the product renewal change need, the packing machinery must have the high flexibility and

28、the flexibility; Three is when the equipment appears the breakdown, the request can carry on the long-distance diagnosis service; Four, favors the environmental protection, the noise, the dust and the reject are few; Five is the equipment purchase investment are as far as possible few, the price mus

29、t be as far as possible low. Therefore, must certainly in the market investigation and study foundation, the full understanding, analyze the user earnestly the demand, the definite packaging machine should complete the function and each technical specification, draw up the preliminary principle desi

30、gn proposal.The modern packaging machine design process should include: The market investigation and study, the user demand analysis, the packaging machine function determination, the feasible proof, the formulation design proposal, the user benefit analysis, the plan feasible proof, the schematic d

31、iagram design, the structural design, the construction drawing design, the prototypical manufacture (hypothesized manufacture), the technical confirmation and the construction drawing revise, the formulation post-sale service predetermined plan and the long-distance diagnosis plan, the improvement d

32、esign, the serialized design and so on. .The market investigation and study is the foundation work which all packaging machines design. Without the market investigation and study, we do all design work all possibly is equal to the zero. The market investigation and study, may according to the policy

33、 guidance, the profession supply and demand information, the expert analyze, the profession unfolds clues and so on meeting, technical meeting, found the user the demand information, after and reorganizes the analysis, the definite packaging machine should complete function. In the principle project

34、 design process, first must understand fully the related information product, the electronic products function, understood the air operated part the performance, and uses to simplify the mechanical drive system, but also may use the multi-electrical machinery dragging to reduce the mechanical transm

35、ission chain. Regarding the essential mechanical drive system, should make the best the modernized design method, in to product functional analysis foundation in, through innovation idea, system modelling, mechanical analysis, dynamic optimization, thus obtains the best design proposal. The technica

36、l design is the principle design structurization, definite spare part quantity, the shape, the size, the material and so on, the essential components carry on the power computation, the power computation, the strength calculation, the rigidity computation to the major component in.When system design

37、, must consider the entire packaging machine system comprehensively the layout, the movement coordination, the modelling design, the human - machine environment as well as the packing transportation and so on. The modular design is one advanced design method, its core thought is divides into systema

38、tically according to the function certain modules, the identical function unit designs the packaging machine in has the module which the different performance, may exchange, through the module different combination, causes the packaging machine multi-purpose, the seriation. Uses this method the meri

39、t is: (1) makes the packaging machine renewal speed to speed up. Because of the new type substitution, often is the partial improvement. The vanguard technology introduction corresponding module, compared with easy to realize the partial improvement; (2) reduction design cycle. After the user propos

40、ed the request, only must replace the module, or the design manufacture partial modules, then obtain the new type, meets the user need; (3) reduces the cost, is advantageous for the service; (4) performance stable reliable. Because time module design, to the packaging machine function division and t

41、he module design, has conducted the careful research, has guaranteed the module performance, for example: Cam gear, servo, examination system, transmission system, control system, measurement organization, yummy treats organization and so on. . other packing machinery seriation, modular profession s

42、tandard, also arrived should formulate, the packing machinery has become our country one of ten big mechanical professions, but serialized, the modular profession standard formulation will certainly to promote our country to pack on the mechanical profession cross new stair.包裝機械的發(fā)展我國包裝機械行業(yè)起步于20世紀(jì)70年

43、代，在80年代末和90年代中期得到迅速發(fā)展。已成為機械工業(yè)中的10大行業(yè)之一，無論是產(chǎn)量，還是品種上，都取得了令人矚目的成就，為我國包裝工業(yè)的快速發(fā)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(jìn)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(jìn)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)品、隱形產(chǎn)品及延伸產(chǎn)

44、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。 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)

45、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(jìn)口的設(shè)備都是國內(nèi)不能制造或者制造水平相差甚遠(yuǎn)的，從進(jìn)口可以看出我們的差距所在。 食品安全問題舉國關(guān)注?！笆晃濉逼陂g應(yīng)提高食品安全領(lǐng)域的科技和裝備水平，研制快速、準(zhǔn)確鑒定食品中危害因子的技術(shù)和裝備，進(jìn)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。總體發(fā)展雖然較快，但食

46、品包裝機械工業(yè)發(fā)展更快。“十一五”的目標(biāo)是要縮小這個空間，為食品工業(yè)趕上世界先進(jìn)水平，為使包裝大國向包裝強國邁進(jìn)，提供先進(jìn)的技術(shù)裝備，讓進(jìn)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(dá)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(biāo)，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(jìn)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(yuǎn)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)常見的故障時可以自行診斷，亦可實行遠(yuǎn)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手調(diào)整動作幅度，保證不反彈。另一方面，各種不同的
