平缝机跳线故障成因及机修工考核方法

Discussion of the causes of wire jump failure of flat sewing machine and the inspection methods of machine repair

针对平缝机最常见的跳线故障,从机针、旋梭、压脚、针板、针杆、送布牙、缝料、缝线等角度具体分析了跳线的成因,并提出了有针对性的解决方法.面对服装生产企业机修工技能考核方式的难题,以跳线故障为例,根据跳线成因逐项考核机修工能否在规定时间内把平缝机从正常运行状态调至跳线故障状态,再从故障状态调回正常状态,根据其调试时长和质量判定其维修跳线故障的技能水平,为服装生产流水线建立完善的机修工考核体系提供了新思路.

Aiming at the most common jumper fault of sewing machine, the causes of jumper wire from the angle of machine needle, rotating shuttle, press foot, needle plate, needle bar, feeding teeth, sewing materials, sewing thread and the solutions are analyzed, Faced with the difficult problem of the examination method of machine repair skill of garment production enterprise, we take the jumper failure as an example, check whether the machine repairman can turn the sewing machine from the normal running state to the line fault within the specified time, at the same time from the fault state back to the normal state. According to the length of debugging time and the quality level of debugging, the skill level of machine repair to solve the jumper fault is determined. It provided a new way of thinking about the establishment of a complete overhaul inspection system for the garment production line.
