Liquid weighing and mixing device
专利汇可以提供Liquid weighing and mixing device专利检索，专利查询，专利分析的服务。并且PURPOSE:To weigh and mix plural raw liqs. by using a closed-loop weighing controller for changing the flow velocity of the liqs., and controlling the weighing controller based on fuzzy logic reasoning. CONSTITUTION:When two kinds of liqs. are weighed and mixed, for example, a weighing set value is set to the weighing controller 3. When the start of weighing is indicated, an opening adjusting valve 7 is controlled to the estimated opening by the weighing controller 3, and the flowing out of a raw material is started. In this case, the initial opening of the opening adjusting valve 7 is calculated from the flow rate characteristic of the valve and the weighing set value based on fuzzy logic reasoning. The raw material in a tank 1 is transferred to a tank 2, and the weight of the material is detected by a load cell 4 and fed back to the weighing controller 3. The opening is operated from the actual weight value by the weighing controller 3 based on fuzzy logic reasoning, and the appropriate opening of the valve is obtained in the succeeding control cycle. When the weighing deviation is reduced after the weighing is started, the opening of the opening adjusting valve 7 is reduced, and the weighing is discontinued when the opening is reduced to lower than a certain value. Weighing is switched to a tank 11, and weighing is carried out in the same way.，下面是Liquid weighing and mixing device专利的具体信息内容。
