Application Of The Wavelet Analysis In The Fault Diagnosis Of Rotating Machines

Printing industry involves a number of fields;include banknote printing,Bookbinding,news,advertising,stationery,packaging,maps,special printing,and labels.The total turnover of China's printing industry is more than 1 trillion,and the printing company is over 100,000.China's printing is one of the most important and rapidly growing markets in the world.Modern pre-press(including printing)stage has achieved an efficient automated mechanized production,but the after procedure requires a lot of manpower to complete production and processing,so printing industry belongs to labor-intensive industries.At present,the market requires small orders and fast delivery,printing industry is enthusiastically launching Lean Manufacturing because of the impact of the world financial crisis and the mainland domestic labor costs.Lean Manufacturing gets rid of geographical restrictions and cultural environment in theory,and develops the system and method that suitable for promoting in the different countries and regions.When implement the Lean Manufacturing,due to different industries and different companies have their own unique characteristics and operating rules,and they also faces different difficulties and limitations,how to put theory into actual real Lean Manufacturing is becoming a common problem faced by a large number of manufacturing enterprises.As one of the world's largest printing company,AS Printing Ltd.offers one-stop packaging and printing solutions,the company also suffered a great challenge to deteriorating external environment in recent years.AS Printing Ltd.implemented the Lean Manufacturing reform started from 2012.The progression and steps to implement Lean Manufacturing in AS Printing Ltd.is that,first set of the pilot and then from the point to the line,the last line to the surface.The company set up the Lean Manufacturing model workshop focuses on promoting several most basic Lean Manufacturing projects,and promote the projects to the company-wide production departments after have successfully implemented of these projects and gained experience,then extended the projects to all departments of the company for full implementation of improvement.With the rapid changes in the continuous expansion of business scale and market environment,AS Printing Ltd.also failed to avoid a series of problems occurs in company's growth process as some big companies,e.g.the defect of the original "linear functions" structure appears,customer demand is uneven,the method of production planning is falling behind,the core talents system cannot effectively support Lean transformation,does not establish the appropriate Lean Production System,ect.AS Printing Ltd.urgently need to improve and eliminate the factors that obstruct the implementation ofLean Manufacturing.AS Printing Ltd.need to construct the new Lean strategic planning,resolve the fundamental problems based on the system,and achieve to the business continuous growth adapting to the new situation.The paper has researched and diagnosed AS Printing Ltd.'s policy for implementing Lean Manufacturing.Taking the necessity for the company needing to implement Lean Manufacturing as the starting point,deeply analyzed the strategy of the implementation of Lean Manufacturing and extract the strategy's value.Analyzed the condition,problems limitations and obstacles for the company implemented Lean Manufacturing.For the problems that AS Printing Ltd.implementing lean production strategy,the paper clearly put forward the strategic planning should be corrected and amended accordingly proposal problems.That should include redesign the organization according to the product structure,improve logistic based on the organization structure transform,corresponding information stream reform,fully promote the wisdom and integration of the product scheduling,introduce the international Lean Manufacturing evaluation standard,implement Lean talent cultivate project,establish and implement Lean personnel system,construct the ideal model of Lean Manufacturing,achieve to transmutation of Lean Manufacturing methods and the continued growth of management level and effect,profit finally.The main method of the present paper includes analysis of survey data,observation site investigation,interview,workflow method,expect demonstration,etc.
