Filling Stability Control Optimization Based On 6? Managment

Filling machine is widely used in food industry,chemical industry,medicine industry,daily necessities industry and so on,and it began to used in the other application fields,it became to be an important part of packing line.With the fast-economic development,and the improvement of technology,the filling machine as the indispensable part of food machine and medicine machine,has undergone sweeping changes in the last 40 years.From the manual to semi-automatic,to the fully automatic,the machine mechanical structure become more and more complex.And the filling speed become more and more quickly,output from hundred per day comes to thousand per minute,speed up thousands of times.The on-line monitoring device,the devement of complete metering device,the image processing device,which provides more space to the intelligence of filling machine,which makes the equipment replacement more and more heavily.Particularly the modern market demands expanding,and the consumer demand for the commodity quality is steadily inproving,which makes the filling equipment entered the fast lane of development.But,for the manufacturing factory who using the filling machine,purchase one set of it will cost too much,may be millions of dollors.It is not economic if the new equipment be replaced befor it reaches the useful life.But keep using the old type of mechine which may faced with the inefficiency and low output,it makes the company be difficult to keep a favorable position in the brutal competition.The company B is a large-scale international enterprise,who need to keep the favorable position,be survival,developed and growth,it needs not only upgrade equipment spare no effort,introduce new techniques,but also optimize the existing equipment continuously,to provide higher quality and lower cost products.With the increasing competition of the market,and the more requirement from the consumers,the modern filling Fust the indicator of increased speed,at the same time,keep eye on the filling stability also,to improve product quality and enhance the market competitiveness.The two important technical indicators of filling are: rapid filling speed and accurate filling.But these two are difficult to balance: the fast filling speed makes it difficult to provide sufficient time for measuremtne of constant volume,but too slow filling speed makes it hard to filling out enough product within a limited amount of time,reduces productivity.So,in order to make each filling operation within a limited amount of time get a qualified product,which means that keep the amount of daily output,obtain the maximum filling volume stability,to reduce the dispersion degree of filling,to compreess the range of change as much as possible,reducing the level of ?,to keep the stability of product quality,so as to improve the quality and reduce the cost.There are too many factors can impacted the filling stability ? level.From the design of piple line,the pressure of pump,the distributing of filling nozzle,the valve action response speed,the running programe of PLC,the feedback signal detection,the valve system,the tank and so on,are the factors that affect the filling stability.it is a significant amount of work for detection and analysis all the factors,without very much reward.How to find out the most important factor and then optimize the key factor to improve accordingly? It is very important to achieve a multiplier effect.Focus on the filling stability whit an in-depth study on this subject,using 6 ? management tools by the Classic DMAIC resolution process,though the process control flow analysis,collecting data,gathered and analyzed,get the machine CPK,and experiment of DOE to the equipment,Define,Measure,Analyze,optimize and Improve & validation,applicate and Control,keep the filling volume of each product in target levels.In the whole process,discuss the application of 6? management in medicine industry constructively,and popularization and application of DMAIC improvement mode in manufacturing.
