Abstract: In order to solve the problems of the granulated material automatic weighing, according to  the characteristics of granulated material, the granulated material automatic weighing machine based on PLC was established A method was presented to improve the automatic weighing machine speed and accuracy effectively, that used frequency conversion motor driving synchronous belt rough charging and vibrating feeder fine dosing The weighing experiments were evaluated on the granulated material automatic weighing machine, the several kinds of drug were tested The experimental results show that the equipment has high weighing accuracy and weighing speed, the characteristics of the operation is stable and reliable, and the equipment can satisfy different granulated drug automatic weighing requirements

Key words: granulated material; automatic weighing machine; weighing accuracy; weighing speed
