为了提高伦敦金银市场协会(LBMA)1 000盎司标准银锭的生产效率,从生产物流的角度分析了1 000盎司标准银锭的生产工艺,删除了生产物流中的多余动作,优化了物流过程,设计了一套银锭自动化铸造线。研制了铸造线的关键设备:银锭铸造车,它把烘模、7块银锭逐一浇注成型、反馈浇注质量信号、补温缓冷、脱模等物流动作集中在一台单体设备上。通过试生产表明,铸造线能够缩短银锭制造时间36.5%、搬运时间94%、搬运距离91.6%,减少操作人员40%,提高成品率5.33%,生产出符合LBMA要求的1 000盎司标准银锭。
In order to improve the production efficiency of 1 000 ounce standard silver ingots by the London Bullion Market Association (LBMA), the production process of 1 000 ounce standard silver ingots was analyzed from the point of view of production logistics, the unnecessary movements in the production logistics were eliminated, the logistics process was optimized, the design A set of silver ingots automated casting line. It developed the key equipment of casting line: silver ingot casting car, which casts the baking mold and 7 silver ingots one by one, and feeds back the quality signal. The logistics actions of slow cooling and mold release are focused on a single equipment. The trial production shows that the casting line can shorten the silver ingot production time by 36.5%, the delivery time by 94%, the transportation distance by 91.6%, reduce the operator by 40% and increase the finished product rate by 5.33% to produce 1,000 ounce standard silver ingots meeting LBMA requirements.
