船用针阀体轴类工件的自动化生产线设计与实现

Shaft automatic production line design and implementation of marine injector valve

为解决某公司多品种小批量船用针阀体轴类工件自动加工需求,设计了基于杰瑞机器人多种工作模式下的自动生产线。先分析船用针阀体工件加工工艺流程,结合机加工序排序原则和生产节拍匹配,设计了基于1台自动上料机、5台数控机床、4台缓存台、2台桁架式机器人、1个工件中转放置台的生产线总体布局;采用S7-300 PLC对自动化生产线进行总体控制,定义了主控PLC输入输出信号类型、程序结构及系统工作模式;最后给出了2个机器人工位的自动化加工流程,并在客户现场完成整套系统的搭建。经过试运行,该生产线运行稳定。

In order to solve the need of automatic processing of multi-variety and small-batch marine injector valve,a new automatic production line based on JARI robot was designed. The production line composed of one automatic feeding machine,five CNC machine tools,four material tables,two gantry robots and one temporary station by analyzing the manufacture procedure and production cycle of marine injector valve. The PLC was used as a main controller for the production line. The PLC input output signal type,the program structure and the system working mode were defined. The automatic processing flow of two robot stations was given,the whole system is set up at the customer site. The production line was stable.
