1、Comment on medicines and chemical reagents package machinery conceptual designIn recent years, Carry out GMP (medicines and chemical reagents produces specifications of quality) attestation system because of sustained our country economic situation rise and country to pharmacy industry mandatory. Me

2、dicines and chemical reagents package machinery has got quite great progress. The new product increases by gradually. Engineering level has had very big improvement. But be returning very big gaps back to existence compared with international standards. Level being close to 60%s product cannot to re

3、ach upper developed country century eighties. Large-scale advanced equipment is dependent on entrance mainly. Low our country medicines and chemical reagents package machinery engineering level is that the design designing personnel low level from our country enterprise arouses to a great extent.One

4、, our country medicines and chemical reagents package machinery current situation analysesOur country medicines and chemical reagents package machinery still has bigger gap compared with advanced international level. What time is insufficient on domestic medicines and chemical reagents package machi

5、nery design under main existence1) Backward domestic mechanical performance medicines and chemical reagents package machinery mostly, accuracy low velocity, is slow, stationarity dispatches package machinery travel process to contain large amount of dyadic complicated intermittence motion. Come to c

6、ome true mainly from the cam, the connecting rod. But, many design that the personnel is unable to require that the independence designs the parameter calculating cam bar linkage kinematics and dynamics according to job cycle picture and accuracy. Be only the surveying and mapping carrying out a pie

7、cemeal that the abroad model machine cam connecting rod part is dismantled down simplely. Bring about actuating mechanism error is very big. That domestic medicines and chemical reagents package machinery runs speed mostly is more general than hanging down according to cutting frequency if the alumi

8、nium moulds bubble cover packers for 100 one 300 mins, full-automatic medicine box packer dress box speed 50- 200 boxes/ ms in. But, on the international, the advanced aluminium moulds rushing steeping cover packer cutting frequency be able to reach 600 mins. Full-automatic medicine box packer dress

9、 box speed is able to reach 600 800 box/ mins. Not only working speed of domestic medicines and chemical reagents package machinery is slow. And, the partner has bigger noise.2) Is under the control of horizontal backward. Domestic medicines and chemical reagents package machinery controls low, auto

10、mation of level difference mostly , the malfunction leads height. (Main package machinery finger box dress controls domestic medicines and chemical reagents with drinking wine holding machinery with) adopt PLC to do a scene mostly. But, advanced medicines and chemical reagents package machinery real

11、izes supervisory control abroad mostly from computer system. Under the control of horizontal relatively backward. Great majority domestic medicines and chemical reagents package machinery automation sex is relatively poor. Adopt a single to produce a pattern first commonly. The full-automatic produc

12、tion line is few. Two is that full-automation works cannot to achieve. Require that the manpower feeds in raw material. Hand movement enchases. If in a little paper box packer, Page, paper box all needs medicine board , specifications paper to move charging personally. And require specially-assigned

13、 person to pay attention to if specifications, medicine board, paper box already finish using at any time. Happen to avoid bringing about machine racing or bringing about incomplete specifications, medicine board, and medicine box phenomenon. Other, domestic medicines and chemical reagents package m

14、echanic failure rates are higher. Control a component (if the relay, electromagnetic valve, contactor, breaker etc.) etc. are often easy to damage. Halt also to frequently occur the malfunction.3) Functions are unitary, expansion sex is bad. Medicines and chemical reagents package machinery is that

15、the form designs that specifically for specially appointed package. The general specification range inner in regulation is adjustable. But, a lot of our country medicines and chemical reagents package machinery considers insufficiency when designing that. Be not that reforming going a step further s

16、ets apart sufficient space. Cause the machinery designing that to be able to only adapt to the form board in several kinds simplicities. Change not adapting to wrapping material or the form board dimension. Fit in with even. The package finished product mass giving birth to a child is neither nice.4

17、) Considers deficiency synthetically. Resource does not fully utilize. Our country medicines and chemical reagents there exists the chaos phenomenon in package machinery design. A lot of machinery designs that the personnel drags to the electric motor moving the synchrony technology, the servo drive

18、 technology do not knows. The problem simple electrical equipment available is resolved uses complicated mechanism to come to come true but. Some though the control organ works to come having adopt the synchrony electric motor to wait for a device. But choose block of wood ding-dang. The maximum hav

19、ing brought about resource not only wastes this condition. And make machinery function designing that low.5) Model is inflexible. Model seldom considering machinery time medicines and chemical reagents of our country package machinery design. Many machine molding that the manufacturer produces is no

20、t beautiful do not have model even. Give person feeling to rigid, to inflexible, not to have vigor. A few medicine box packers are middle. The nut all assembles screw on the machine outside board. But, the oil cup and flow nipple that a little lubrication uses also can be seen everywhere. Be stained

21、 fully with a greasy dirt easy to use machine everywhere time oiling. Impression is rough to person. No beautiful.Two, medicines and chemical reagents package machinery conceptual design contentPeople long-term study passes. Define conceptual design being: Have been ascertaining the mission queen. P

22、ass abstract-relation. Design the function structure. Explore appropriate effect principle and their combination waiting. Ascertain out basic finding the solution approach. Reach find the solution scheme. This part of the conceptual design designing that the job is called conceptual design is referr

23、ed to make the queen who designs purpose and now has condition clear. The designer searches for many-sided knowledge. Analysis abstracts the solution on generating dyadic broad frame significance the day after tomorrow. Medicines and chemical reagents package machinery conceptual design demands acco

24、rding to each product life cycle stages. Carrying out the product function creates , the function breaks up as well as the function and son are functional physical design: That conception and systematization carrying out the scheme satisfying the operating principle that the function and structure d

25、emand finding the solution and carrying out the operating principle carrier realizing the function structures design the conceptual design process is that one finds the solution realizing a functions , satisfies the various technology and various there existing in economic targets , possibility sche

26、me well ultimate for sure synthetically optimum scheme process. The conceptual design effect embodies in the product design early phase stage mainly. Chief architect is based on functional need of product but primitive conception and impulsion sprouting out form the product main body frame. And, it

27、responds to every main module and module including. In order to accomplishing overall layout and the exterior, the first step designs that. And then carry out the optimization appraising a sum. Ascertain the overall design plan. Design that the personnel carries out the chief architect design though

28、t going to designing middle concretely again from every part. Detail designs realization. The conceptual design putting medicines and chemical reagents package machinery into practice demands to design that the personnel reinforces the cognition to medicines and chemical reagents package first. Deep

29、en the connotation understanding medicines and chemical reagents packages. Introduce modern package idea. Be in line with the international conventions actively. Modern package is to ensure the product safety not only. Make product transportation convenient. And be getting up propagate, environmenta

30、l protection, defends against false. Attractive looks waits for the many-sided effect. Wrap up contents additional information. The medicines and chemical reagents package machinery design personnel should show solicitude for development of package system closely. Go deep into the handicraft studyin

31、g package. Know demand of development of wrapping material and the person to machinery product very well. Only when such ability designs that out satisfy the high tone machinery product that the consumer demands. Medicines and chemical reagents package machinery conceptual design content has mainly:

32、1) Makes the design mission clear. Be ready for feasibility analysis. The designer designs initial stage working in being in progress. Respond to the feasibility considering a product sufficiently. One aspect is the marketplace thinking. Include the production marketing, product raw material, the fa

33、bricating cost thinking: Another aspect is thinking that the product processes. Include thinking now having a working ability, processing handicraft, processing the function and periphery supporting industry. Periphery supporting environment thinking points to the local enterprise working ability ma

34、inly processes level, heat treatment handicraft and the infrastructural facilities construction etc.2) Function design. Great majority our country medicines and chemical reagents package machinery is the same kind model copying to abroad. But peculiar national conditions because of our country exist

35、ence. Must carry out appropriate reforming on the product. To satisfy request of our country. But fault blindly copy blindly. The machinery designing that is packed in, irrigates the dress function outside except needing to satisfy a box. We must consider the additional function packing machinery. I

36、f in package box should add a counting cup. The medicine spoon waits an utensil down. Be put into use with convenience of customers. In machine, kind of aspect developing can design comparatively advanced machinery. If sterile pack machinery, the package machinery retaining freshness etc.Can develop

37、 the corollary equipment selling complete sets of equipment and the post-processing at reduced prices in the medicines and chemical reagents package front.3) Functions decomposition. Medicines and chemical reagents package machinery belongs to the integration of machinery with electronics product. S

38、hould consider every function all round time design. Sort Er Yan. The medicines and chemical reagents package machinery function may divide 3 major parts being that organization moves, monitors biography feel, the information processing and controlling a function basically. The function subdivides o

39、rganization motion according to may not kind with machine , packer may be molding , heat-seal , pressure trace mark, according to cutting 4 big functions if the aluminum moulds bubble cover. But, paper box package machinery may be that the box opens, paper box transfers, breaks tongue , functions su

40、ch as inserting tongue , flattening and putting a batch number up mark poison board under paper folding, deducing paper feed. Want to consider machinery lubrication, safe functions such as running, packing hygiene of machinery too in the process of design. This demands the technology designing that

41、the personnel considers detecting sufficiently. Brightness, machine, electricity integration technology, computer art. Intersection between the pneumatic technology, the logistics technology connection.4) Organization is designed. Be to realize the predetermined function. We need to use different or

42、ganization. This needs the part synthesizing each considering a complete machine among one process. Use the product designing that while satisfying the usage request. Structure is simple, pragmatic. Medicines and chemical reagents package machinery organization designs time. Respond to the principle

43、 choosing appropriate organization motion and constituting. Think sufficiently to realize what specially appointed motion needs organization. If cam organization. Bar linkage. Cam bar linkage. Respond to the technology wielding separation drive at the same time. Think that the transmission shaft des

44、igns a problem (if castellated shaft and ladder axis etc.) and drive are systematic synthetically. Design that process middle should cut down the effect that the uncertainty factor brings about to the full. Messenger organization operation is stable. Design that machinery carries out kinetic methods

45、 of analysis answering now and then. With lifting, machinery runs speed and stationarity. Should think that various packing machinery, adjustable, holds the mistake, but expansion, stationarity as well as beautiful-rization besides. Run after machinery is deft but stable. Design process but consult

46、package machinery design of all kinds strong point. Draw other machinery (if plastic machinery, prints machinery) merit at the same time. Design the outside except carrying out organization. Return approach back to the realization should think that every function is other. If vacuum, electrical equi

47、pment waits under the control of. To expect that optimum combination is a products turn.5) System under the control of schemes design. In medicines and chemical reagents package machinery, a very important part is that real time detecting is back-off to every organization. To ensure that equipment o

48、peration is smooth. Now many machinery products has selected and used large amount of photo electricity switch being the detecting component. Equipment has such as PC detecting bubble cover system on some machinery and the like system. This need all designs that meticulously. And, the general naval

49、company is an integral whole.Three, concluding remarksThe thought a concept is designed melts to enter medicines and chemical reagents package machinery design being able to fall off designing a fault. Shorten a design cycle. Accelerate the product exploitation. Make the product designing that more rational, have affinity, more suitable man-machine project more. It is also that the main means costing down and improving enterprise competition is short of passive competition aspect backward for improving medicines and chemical reagents package mac
