摘　　要：为了解决颗粒状物料自动称量的问题,根据颗粒状物料特性,研制了一种基于PLC的颗粒状物料自动称量机,该系统采用变频电机驱动同步带进行粗加料和振动给料机精加料结合的方式,有效提高了自动称量机的速度和精度。对不同种类的颗粒状药品进行了称量试验,试验结果表明,该称量设备具有精度高、称量速度快、运行稳定可靠的特点,且可以满足不同颗粒药品的自动称量要求。In order to solve the problems of the granulated material automatic weighing, according to the characteristics of granulated materi- al, 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. Tile 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,
