设计了一种主要用于有毒、易挥发性液体的全自动液体定量灌装机。 其控制部分设计主要包括 PLC 控制空桶的输送、桶口的定位、液体定量灌装、满桶的输送等工作。 采用的计量仪表为 F701 称重控制器,通过PLC 的控制实现精确称量。 在整个液体的定量灌装过程中,不需要人工接触灌装液体,设备能够实现全自动的系统工作。 对设备系统的软件、硬件进行了详细介绍与分析。

A kind of automatic quantitative liquid filling machine mainly used for filling toxic and volatile liquid was designed. The control part includes bucket conveying, bunghole positioning and quantitative liquid filling and pailful of transportation and other work under PLC control. The measuring instrument is F701 weighing controller, which achieve precise weighing through PLC control. In the whole quantificational filling process, people are not needed to contact filling liquid. The machine will complete working process automatically. The hardware and software design of automatic quantitative liquid filling machine control system was introduced and analyzed in detail.
