【摘要】:石材臺面板制品的需求量日益增多,并呈現(xiàn)出向多品種大批量生產(chǎn)模式發(fā)展的趨勢。由于缺乏足夠的柔性和合理的設備布局,傳統(tǒng)的固定串行生產(chǎn)線存在生產(chǎn)能力冗余或不足的現(xiàn)象,且搬運距離長,搬運次數(shù)多,勞動強度大,無法滿足大批量定制的要求。因此,開發(fā)推廣兼?zhèn)涓呱a(chǎn)力和足夠柔性的可重構(gòu)石材臺面板生產(chǎn)線,已成為我國石材企業(yè)擴大生產(chǎn)規(guī)模、開拓生存空間的關鍵。本文從生產(chǎn)線總體規(guī)劃、產(chǎn)品族工序識別和劃分、可重構(gòu)石材臺面板設備開發(fā)、物流系統(tǒng)設計、布局規(guī)劃及建模仿真等幾個方面對可重構(gòu)臺面板生產(chǎn)線進行了系統(tǒng)研究。 通過對現(xiàn)行臺面板生產(chǎn)方式中所存在問題的分析,構(gòu)建了可重構(gòu)石材臺面板生產(chǎn)線系統(tǒng)的集成框架,從系統(tǒng)層和設備層兩個層面詳細闡述了系統(tǒng)設計過程中涉及的使能技術,并每個層面的應用層使能技術進行了研究。 基于位置公差和κ-平均算法對石材臺面板產(chǎn)品族進行工序劃分,使可在同一設備上完成的工序分配在同一工序組合內(nèi),通過對各工序組合的合并和排序,得到了工序族的優(yōu)化組合方案。以所得優(yōu)化工序組合方案為基礎,通過對各工序組合進行加工運動分析,獲得了可重構(gòu)石材臺面板設備所需具備的基本功能。利用模塊化設計方法,將可重構(gòu)石材臺面板設備的總體方案劃分為機械、控制、冷卻潤滑和輔助四大模塊,并將機械模塊進一步劃分為運動、動力、支撐和擴展四個子模塊,進而對各子模塊進行初步結(jié)構(gòu)設計,通過各模塊的組合生成可重構(gòu)石材臺面板設備的配置圖,利用Solidworks構(gòu)建了設備的三維模型。 通過分析確定采用輥子輸送機配以真空起重機組成具有一定柔性的物流傳輸系統(tǒng),并分別對輥子輸送機和真空起重機進行了結(jié)構(gòu)改進。通過對直線型、U型和單元式三種布局形式的分析,結(jié)合石材臺面板的生產(chǎn)特點,確定采用U型與單元式相結(jié)合的布局方式。為了使可重構(gòu)石材臺面板生產(chǎn)線具有足夠的柔性,采用基于可重構(gòu)單元的生產(chǎn)線結(jié)構(gòu),結(jié)合混合整數(shù)規(guī)劃模型完成了可重構(gòu)單元構(gòu)建;谝陨涎芯績(nèi)容,獲得了可重構(gòu)石材臺面板生產(chǎn)線的規(guī)劃圖。由于物流設施的合理選擇與布局,可重構(gòu)石材臺面板生產(chǎn)線的搬運距離和搬運時間僅為現(xiàn)行生產(chǎn)方式的1/2和1/5。 為了了解可重構(gòu)石材臺面板生產(chǎn)線的系統(tǒng)性能,并與現(xiàn)行臺面板生產(chǎn)方式形成直觀對比,基于EM-Plant仿真軟件對可重構(gòu)石材臺面板生產(chǎn)線系統(tǒng)進行了建模仿真研究。通過對生產(chǎn)線的性能指標和瓶頸分析,得出以下結(jié)論:用于兩種不同產(chǎn)品加工時,生產(chǎn)線的月產(chǎn)值可以分別達到2784件和2726件,完全滿足期望值;平衡率可以分別達到79.2%和84.6%,生產(chǎn)較穩(wěn)定;負荷率較高的設備作業(yè)時間小于生產(chǎn)節(jié)拍,不存在生產(chǎn)瓶頸。 山東省科技發(fā)展計劃資助項目(2010GGX10405,2010GZX20604)。
[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.
