目的设计一种适合于涂料灌装的自动灌装设备,以提高灌装过程的自动化程度,提升灌装精度。方法采用双头分别灌装,将灌装时间分散,压缩设备准备时间;采用伺服电机和滚珠丝杠代替原有气缸驱动,利用伺服电机重复定位精度高的特点提升罐装精度。设计相应的控制程序和界面便于生产过程中设备参数的调整。结果针对5 L包装桶的灌装效率为每桶2 s,灌装精度达到±5 m L。结论通过实际生产证明该设备能够适用于各类流动液体物料自动灌装生产。双头伺服驱动容积式灌装机能够作为独立设备单机使用,也可通过以太网与控制设备通讯,作为灌装生产线的一部分配合其他设备使用,能够实现生产状态的在线监测和生产参数的远程控制。

The work aims to design a kind of automatic filling equipment suitable for paint filling, to improve the automation of filling process and improve the filling accuracy. The double heads were used separately for filling and the filling time was dispersed, so that the preparation time of the equipment was shortened. The servo motor and ball screw were used to replace the original cylinder drive. Based on the high accuracy of repeated positioning of servo motor, the filling accuracy was improved. The corresponding control procedures and interface were designed to enable the equipment to adjust its parameters in the production process. With respect to the filling efficiency of 5 L packaging barrel（2 s per barrel）, the filling accuracy reached ±5 m L. Through the actual production, it proves that the equipment is applicable to the automatic filling of all kinds of flowing liquids during the production. The double-head servo driven volumetric filling machine can be used as a stand-alone equipment and communicate with the control equipment through Ethernet. As an integral part of the filling production line, the double-head servo driven volumetric filling machine, combined with the use of other equipment, can achieve the online monitoring of production status and the remote control over the production parameters.
