Work Study For The Furniture Rough Mill Section

The rough mill section of furniture plant usually has the properties of bad environment, high work load and instable productivity and so on ,which are the important factors that restrict the furniture productivity. So, improving the efficiency of the furniture rough mill section is significant to the whole plant. Based on the ergonomics principles and industrial engineering methods (work study), this study emphasizes on how to improve the work efficiency of the rough mill section under existing work conditions.First of all, this study discussed the theoretical basic and principles of how to improve the work efficiency, analyzed the compositions of the work time, and brought forward the idea of eliminating the time waste from macrocosmical and microcosmical levels. Meanwhile, I brought forward a systemic model to establish a new way to study the work efficiency from three aspects: the materials flow and plant layout, the time study to the work procedure, and the motion study to the certain workplace.On the concrete study, I selected three different kinds of furniture company A, B and C (state, personal and foreign capital furniture company) to analyze, compare and improve. I hoped to find some prefer measures up to their actual condition. According the characteristics of the process of furniture rough mill section, I relocated the workshop and selected the corresponding conveyance. The time study mainly analyzed the percentage of varies of time expenditure from macroscopical view, emphasized on decreasing the noneffective time by some management ways and increasing the ratio of normal working hours TH. However, the motion study mainly studied the operation process of a certain workstation from microscopical view, tried to improve the operation methods and the workstation, eliminated the noneffective motion during operation. It emphasized on improving the operation speed by some technology ways.At the end of this study, I had measured the heart rate of two workers during their working in the rough mill section and recorded their corresponding activity. I wanted to study the relation between their activities and the heart rate during working.After a series of studies mentioned above, I had gotten the following conclusions:I had analyzed the technical process of the three plants and improved their layout. It can reduce the material flow and make the manufacture and management activities more convenient. In this aspect, the amelioration effect is obvious for the plant A and B.The normal work time ratio(T11%) of the three plants A, B and C is 44.2%, 67.7% and 66.8% respectively, which indicated that the property of company and their management modes greatly impact the work efficiency. If we take some measures to improve the work time ratio according to certain principles, their TH% will reach to a high level of 70~80%.The motion study of some workstations showed that the work place layout, the operation methods, the materials' properties and the operation motion are also the important factors which affected productivity. To improve the operation activities according to the actual condition is aimportant way to increase the whole productivity of the plant.Sum up, to improve the work efficiency of the furniture rough mill section is a complicated project. This study mainly provided a guidance to improve the work efficiency form the methods and the contents. I hope this thesis can provide some help to the furniture company.
