Production line is to show subject of labor passes each working centers according to certain craft route, order, and according to fixed manufacturing rate (metre) a kind of production that repeats production of the exercise that finish continuously organizes a form. On automation line pure and one-way sex, successive and efficient sex, specialization, the character that balances gender and dominant sex, decide the content inside the factory flows to exercise must be subject to and serve the need with manufacturing technological process, interweave for core around it in producing technological process, so the content inside the factory flows have very strong cooperate gender, dynamic sex, distributing center sex and balanced sex, at the same time this is planted character is changed as the change of craft of model of manufacturing environment, condition, market, product, treatment again, achieve afresh optimize and balance.
One, the content of production line flows deserve to send contradiction
What exist on 1, product line is contradictory
The content with efficient manufacturing characteristic and small effect, multifarious production line flows deserve to send, become the content inside tie factory to shed a bottleneck of unobstructed. There is the following problem in if some enterprise is having unripe child,shedding transformed process.
(1) although content shed container to have an abecedarian,standardize, but still be to do not have a standard however to the use method of container, pack standardization of not true implementation, standardization, pile up still show mixed and disorderly. On operation effect, essence is switch merely container just.
(2) transform through early days, everywhere content shedding can arrive smoothly on the line, but operate and do not have JIT (the material that deserves to send proper amount and quality only in appropriate time namely tastes proper place) , still have a little surplus, bring about the accumulation of makings surplus increases, pile up online system margin, still affected follow-up stock deserve to send, stop production phenomenon often still arises.
(3) the product of the different type that giant, deal weighs bulk again, cause a worker labor efficiency is low, the product assembles quality to drop; In the meantime, because the product is in,the utilization rate of on-line equipment is reduced greatly, once some equipment on the line or some working procedure gave trouble, make stop machine form vicious circle, affected whole product line thereby move, make the dependability of product line is reduced greatly.
(4) the product line of original set is to have stronger tigidity, poorer to the adaptability of product structure, when change the line of production, the stock fluctuation line on product line is more bustling, the worker because of the center working each on the line already set, this makes the worker is carried demandingly on one hand (especially big) influence production; Often bring about stock to should go up again on the other hand did not go up, this did not fall, makings taste a disorder, make production is run break down nearly.
