基于G代码的绗缝机断线断电恢复的研究

针对现有的绗缝机断线断电后恢复加工产生的位置偏移、重复走线等问题,提出一种关于绗缝机断线断电后恢复加工的方法,提供自动与手动两种恢复方式。绗缝机发生断线断电时,机头自动移动到机械原点位置。自动方式下,上位机根据下位机反馈的断线断电位置,判断断点位置所处绗缝类型,根据绗缝类型的不同改写G代码,从断点处插入改写的G代码继续加工;手动方式由操作者选择轨迹,截取从选定轨迹处绗缝花型文件,生成新G代码恢复加工。

Research on Processing Resuming After Thread Breakage or Power Outage of Quilting Machine Based on G Code

In response to the problems of position deviation and repeated routing while resuming processing after thread breakage or power outage of the existing quilting machine,a method for resuming processing of quilting machine after thread breakage or power outage is proposed,which provides automatic mode and manual mode.In the case of thread breakage or power outage,the headpiece automatically moves to the original point of the mechanical coordinate.In automatic mode,the master computer judges the type of quilting trajectory where the breakpoint is located according to the feedback from the slave computer,G code will be rewritten according to the type of quilting trajectory,and the rewritten G code will be inserted into the breakpoint to continue processing.In manual mode,the system program will capture the file on quilting pattern from the manually selected trajectory and generate new G code to resume processing.
