[Abstract]:The demand of stone tabletop products is increasing day by day, and the trend of mass production is becoming more and more. Due to the lack of sufficient flexibility and reasonable equipment layout, the traditional fixed serial production line has the phenomenon of redundant or insufficient production capacity, and the long distance, the number of times of handling and the labor intensity can not meet the requirements of mass customization. Therefore, developing and popularizing the reconfigurable stone Mesa plate production line with high productivity and enough flexibility has become the key to expand the production scale and open up the living space for our country's stone enterprises. In this paper, the reconfigurable Mesa plate production line is systematically studied from the following aspects: production line master plan, product family process identification and division, reconfigurable stone Mesa equipment development, logistics system design, layout planning, modeling and simulation, and so on. Based on the analysis of the existing problems in the production of table plate, the integrated framework of the reconfigurable stone Mesa plate production line system is constructed, and the enabling technology involved in the system design process is described in detail from the two levels of system layer and equipment layer. At each level, the application layer enabling technology is studied. Based on the position tolerance and 魏 -average algorithm, the product family of stone Mesa plate is divided, so that the processes that can be completed on the same equipment are assigned in the same process combination, and the combination and sequencing of each process combination are carried out. The optimal combination scheme of working procedure family is obtained. Based on the optimized process combination scheme, the basic functions of the reconfigurable stone table plate equipment are obtained by analyzing the processing motion of each working procedure combination. Using the modular design method, the overall scheme of the reconfigurable stone table plate equipment is divided into four modules: machinery, control, cooling, lubrication and auxiliary, and the mechanical module is further divided into four sub-modules: motion, power, support and expansion. Then the structure of each sub-module is designed and the configuration diagram of the reconfigurable stone table plate equipment is generated by the combination of each module. The three-dimensional model of the equipment is constructed by using Solidworks. Through analysis, it is determined that the roller conveyer is equipped with a vacuum crane to form a flexible material flow transmission system, and the structure of the roller conveyor and the vacuum crane are improved respectively. Through the analysis of the three layout forms of linear U type and unit type and combined with the production characteristics of stone table plate, the layout mode of U type and unit type is determined. In order to make the reconfigurable stone Mesa plate production line flexible enough, the reconfigurable unit was constructed by using the production line structure based on the reconfigurable unit and the mixed integer programming model. Based on the above research content, the plan of reconfigurable stone Mesa plate production line is obtained. Due to the reasonable selection and layout of logistics facilities, the distance and time of the reconfigurable stone Mesa production line is only 1 / 2 and 1 / 5 of the current production mode. In order to understand the system performance of the reconfigurable stone Mesa plate production line and make a direct comparison with the current production mode of the Mesa plate, the modeling and simulation of the reconfigurable stone Mesa plate production line system based on EM-Plant simulation software was carried out. Through the performance index and bottleneck analysis of the production line, the following conclusions are drawn: when used in two different products processing, the monthly output value of the production line can reach 2784 pieces and 2726 pieces respectively, which fully meet the expected value; The balance rate can reach 79.2% and 84.6% respectively, the production is stable, the working time of the equipment with higher load rate is smaller than the production rhythm, and there is no production bottleneck.
