Flexible reproducing system and its project application

The treatment facilities of original manufacturing industry or product line are special the gender is strong, the function is single, main purpose is invest with equiping lowly as far as possible, as far as possible rapid manufacturing rate, as far as possible big production lot achieves the biggest beneficial result. Consume the development of means as the flying progress of technical level and people, intense market competition makes current manufacturing industry is abandoning producer of rigid big batch type, xiang Rou sex produces a system to develop, the much breed with getting used to a product, medium the characteristic such as small lot, individuation. Statistical data makes clear, in manufacturing industry of Europe, beautiful, day, the product that small lot produces in is occupied about on the amount 85% , occupy 60 ～ about on production value 70% . The developed country is being built flexible a large number of capital are invested in processing a system, the United States was thrown 1988 3.

4.9 billion dollar, exceeded 2 billion dollar 1990. The raw material that reproducing processes is produce by manufacturing industry, the technology arrives after the course is used or the extreme product of service life. Of the addition of the line of the products that produces as manufacturing industry, batch decrease, of individuation outstanding and the product retires the diversity of the circumstance, offerred an acid test to the development of reproducing industry, ask reproducing estate development goes old to abandoning line of the products and invalidation form adaptability strong, production is periodic short, finished cost quality of low, product is high flexible reproducing system, in order to answer the tremendous change of manufacturing industry. 1 flexible the connotation of reproducing and characteristic are flexible reproducing is with technology of advanced IT, reproducing and management means is a foundation, those who adopt reproducing system is flexible, can forecast gender and optimize control, achieve utmost to reduce reproducing product to produce time, optimize content to flow, rise to answer ability to the market, assure product quality, to how implementation is breed, small lot, different retire extreme product of the form undertakes personalized reproducing. Flexible answer what the purpose of reproducing depends on reaching the market to treatment of reproducing semifinished product, reproducing quickly, through building flexible reproducing produces a system, the type that can improve reproducing product significantly, shorten reproducing cycle, reduce cost, improve reproducing product quality. The material with the same to seeming quality treatment of manufacturing industry reachs component, and the treatment object of reproducing is useless old product. Because abandon old product to differ in the operating mode of enlistment, retire reason inaccuracy of amount of different, origin decides form of different, invalidation wait for a characteristic, make the object of reproducing has the characteristic such as individual sex and uncertainty. Accordingly, flexible for the reproducing system with reproducing relatively traditional system, have apparent characteristic and specific difficulty. Consult in production system flexible the characteristic that assembles a system, knowable and flexible reproducing system should have the following characteristic: Undertake reproducing to a variety of products at the same time; Have hardware and software resource through recombining quickly, realize the reproducing of new type product; The reproducing that undertakes trends answer to different invalidation form is machined; Fast basis market demand, change reproducing plan; Those who have height but expanding, can reframe gender, but sex of put sb in a very important position and but compatibility, realize the product line of modular, standardization. Above characteristic, the personalized element of the product such as the form of the sort that can raise reproducing to get used to useless old product significantly, invalidation, make reproducing product has the capacity that gets used to consumer individuation demand, strengthen the vitality of reproducing industry. 2 flexible the key of reproducing system is unit flexible managing decision-making center is flexible manage decision-making center to be able to transmit ground of dynamic real time to collect each unit data through data, form optimization decision-making, issue an order, realize each element of pair of reproducing enterprises: Personnel, technology, management and equipment are coordinated what wait in real time and automation is controlled, right each personalized characteristics in producing a course are answered quickly, it is flexible the nerve center of reproducing system. It basically is to rely on the data line between each unit and decision-making center and surveillant equipment to finish. Flexible semifinished product of pretreatment center reproducing should undertake tearing open solving above all before reproducing is machined, clean and classify, this is reproducing treatment and the important preparation phase before assembling, belong to the pretreatment phase of reproducing. Of different type product tear open solution, of spare parts of different pollution circumstance clean and the classified keep in storage of the spare parts, have very strong individual sex, use to its flexible change a design, basically be the adaptability that enhances equipment and automation degree, in order to reduce pre-conditioning time, improve quality, reduce cost. Flexible the reproducing repair that treatment of reproducing of reproducing machining center basically includes pair of parts that be short of caustic and upgrade. Flexible the different failure mode that reproducing machining center basically expresses phyletic to differring now component, treatment facilities can undertake automation breakdown detects, choose different equipment to have repair to breakdown. Flexible assemble reach detect the center reachs pair of reproducing product function to the assembly of all component after reproducing detect, it is the final step that assures reproducing product quality and market competition ability. Use modular equipment, can rise to assemble the adaptability that reachs function to detect to different type product. Flexible content fluid is flexible the content in reproducing system sheds main consideration to abandon old product and component to be in reproducing factory in-house the flow between each unit, the demand that the keep in storage in including component reproducing around and reproducing course, stock reachs means, new component in the transmission time between each unit and call, of component and product pack etc, among them important is implementation unit interior is reached between different unit what content shedding transmits is flexible change, make same equipment can get used to much more phyletic component transmit, and the content that reproducing of new type product can get used to after the course recombines spreads demand. Ideal flexible reproducing content sheds a system to have transmit much more phyletic article, adjustable transmission rate, leave a line or control capacity in real time, can reframe quickly, take up to the space the smallest wait for a characteristic. Below good position flexible sketch map of reproducing system frame of 3 ideal flexible reproducing system forms right plan institute to show is reproducing factory interior below good position flexible of reproducing production system constitute sketch map. By the graph knowable, after useless old product enters reproducing plant, enter above all flexible content sheds a system, by content shedding system Xiang Rou sex manages decision-making center to undertake reporting, and the basis is flexible the directive of the management center, enter storage or pretreatment process; Pretreatment center chooses phasing to answer according to the instruction of decision-making center pretreatment method, the useless old product to be being carried undertakes handling, report processing decision-making center as a result, shed the product after processing the system to carry storehouse to perhaps enter reproducing machining center by content at the same time; Reproducing machining center is short of caustic through be opposite specific measure fashion specific production process and report decision-making center! Decide corresponding reproducing method according to the instruction choosing of decision-making center, the automation reproducing rehabilitate of affirmatory component or transform program, shed the component after repair the system to carry storehouse to perhaps be assembled by content according to the instruction of decision-making center next detect center; Assemble detect after the center is receiving the injunction that obtains decision-making center, content shedding the system carries the component that come to undertake the product detects constructional mixing, will detect as a result the report gives decision-making center, carry eligible finished product storage undertakes after go out and be being packed by content shedding system again, rejected product enters the corresponding segment of reproducing afresh according to decision-making center instruction. Finally is basis of content shedding system decision-making center instruction extracts reproducing product in time to put in the market from inside storehouse. Flexible managing decision-making center is in whole and flexible the action in the system is central processor, it receives each unit information ceaselessly, course analysis is backward each unit issues decision-making statement. Above is flexible the information of reproducing factory interior and instruction communication graph, its are flexible change still reflect in equipment but augment, can recombine wait for a respect. Implementation is flexible the equipment of reproducing system is flexible change, the technology is flexible change, the product is flexible changing is a complex systematic project, of the support that needs numerous advanced IT and facility and advanced management method apply. Embryonic form of 4 projects application and characteristic will be flexible when reproducing has project application, what should consider each unit to handle a function not only is perfect, and consider this unit or module to whether conduce to even those who improve whole project system is flexible; Want to improve each hardware function of unit equipment not only, deploy corresponding sensor, supervisory equipment and driver for these equipment even, so that can pass decision-making center,undertake be controllinged effectively to them. In the meantime, better news still should be had to exchange ability between engineering unit, the science that implements a system is decision-making. Normally flexible of reproducing system build need to consider two factors: Manpower and automation, and the person is flexible factor is had most in production. If be built in the project in pure the automation degree that emphasizes a system, and oversight the person's element, what implement automation below the circumstance with immature condition is flexible reproducing system, what require equipment possibly very complex, will reduce the reliability of product quality. Fall in certain condition so, use automation operation and the method that are united in wedlock artificially to build this system, can assure the higher profit of project application. In view of the development level of our country economy and technology, still did not build at present what perfect quite is flexible reproducing system, but the embryo that had had pattern of a few application. Limited company of Jinan answer powerful motive force is a business that produces reproducing engine, through making an on-the-spot investigation, they had built an abecedarian flexible reproducing produces a system. The flexible and decision-making center of this factory basically is mixed by the technical administrator of the company the composition of all of computer science department that is used at information keep in storage and processing, formed information to manage decision-making layer, to each production of the company link undertakes decision-making. Its are flexible pretreatment center is one big job shops, automation line works, undertake different pretreatment to different component. Reproducing machining center also is a big job shops, own a variety of advanced machine tools and finishing facility, can complete spare parts form machine or repair. Its are assembled reach detect the center is comprised by a variety of advanced equipment, can complete different and phyletic engine detect reach assemble. The content between each unit sheds a system to basically be finished by the equipment such as a few automatic forklift, each unit interior flows by the finishing content such as crane. In this system mature the person's element, have fixed automation rate, can finish the reproducing of all sorts of engine at present, manufacturing cycle is short, product quality and taste newly quite. 5 conclusion are flexible of reproducing project system build can shorten reproducing time, increase reproducing line of the products, improve quality, it is the optimal solution that makes sure reproducing gets used to manufacturing industry to develop change. What article place puts forward is flexible crucial and the concept of reproducing system, characteristic, unit ideal frame and project application, what suit to coaching reproducing factory is developed is flexible reproducing system has fair referenced value.
