Description

一种纱线断头监测装置 技术领域
本发明涉及纺纱设备技术领域，尤其是涉及一种用于环锭细纱机纱线断头监测技术领域。
背景技术
在环锭细纱机的制纱过程中，通常将粗纱从吊锭送到喇叭口后进入牵伸机构牵伸，牵伸后的纱线再通过导纱钩进入钢丝圈加捻，并将加捻后的纱线卷绕在绕线筒上。在加捻的过程中，由于纱线拖着钢丝圈在钢领上作高速回转，所以经常出现纱线断头现象。目前对于环锭细纱机的纱线断头检测的方式普遍使用的有机械式、电气接触式、气压非接触式、光电非接触式和温度传感式等，机械式因有动作灵敏度低、易磨损等缺点被淘汰，电气接触式由于导电棒易氧化加之棉尘、飞花堆积等因素的影响，常会出现接触不良的现象，以致控制失灵而被气压、光电和温度等非接触式所取代。
中国专利公开号为CN2556218Y的一种纱线断头检测装置，包括由热敏元件为一次元件构成的传感器及与所述传感器相连接的信号处理器，传感器设置于细纱机纺纱时摩擦起热的部位，包括纱线与导纱钩、钢领与钢丝圈接触的部位，纱线断头后，这一部位的温度下降，传感器将温度值变换为电信号送至信号处理器，信号处理器可在8～16秒内发出信号提示。虽然这种传感器元件少，体积小，但每个纺纱锭位配置一个传感器，成本高昂，另外需要人工来回巡视，劳动强度高。
中国专利公开号为CN202450212U的对射气压式细纱机纱线断头检测机构，包括安装在钢领板上的复数个钢领和设置在各钢领跑道上的钢丝圈，所述钢领板上安装有对应于每个钢领且用于检测钢丝圈回转变化的气管喷头和压力传感器，气管喷头与压力传感器相对设置，气管喷头的中心轴线与钢领跑道的外周面相切，或气管喷头的中心轴线与钢领跑道的顶面重合，且压力传感器的输出端与处理电路连接。采用无触点进行检测得到钢丝圈的回转变化的回转频率，虽具有结构合理，安装方便，检测准确，检测反应迅速等特点，但每个纺纱锭位配置的气管喷头和压力传感器，成本依旧很高，并且需要人工来回巡视，劳动强度高。
中国专利公开号为CN202705616U的赛络纺巡回式纱线断头检测装置，是在每只锭子上安装一个光电开关，把CMOS摄像头安装在巡回小车上，当小车巡回检查时，CMOS摄像头采集图像信号，将包含纱线和周围物体在内的图像信息转换为不同数值的电压信号，由处理器对摄像头传送的图像信息进行分析处理，判断两股纱线是否完好。若纱线完好，处理器控制继电器驱动绿色警示灯亮，同时通过控制电机驱动电路，驱动巡回小车继续前进，检测下一个锭子上的纱线；若检测到单纱或断纱，巡回小车停止并切断单纱，同时红色警示灯亮并发出，提醒挡车工进行处理，但纱厂工作场地范围大，噪音响，挡车工往往看不到警示灯、听不到报警声，巡视强度依然没有有效减轻，另外驱动巡回小车若检测到单纱或断纱，巡回小车将停止，如挡车工没有及时处理，巡回小车将无法继续进行纱线断头检测。还有一种巡回移动检测方式，也是在钢领板前侧安装有一个跑道，将一个磁电传感器安装在跑道上，通过移动的磁电传感器感应出各绽位钢丝圈的转动信号，并通过导线将信号到中央处理器内，以检测各锭位纺纱断头情况，但由于跑道是安装在钢领板的前部，而跑道的存在对于人工操作及清洁工作都带来不便。这两种巡回小车不仅都增加了小车的制造、维护费用，还占用了纺纱机空间，更额外增加了驱动小车行走的能耗。
 发明内容

解决上述技术问题，本发明通过下述技术方案得以解决：一种纱线断头监测装置，包括环锭细纱机、吹吸风清洁机、纱线断头检测装置，其特征是：所述的纱线断头检测装置由无线摄像头、固定件、监控终端和纱线断头位置判别系统组成，无线摄像头通过固定件安装在吹吸风清洁车上，无线摄像头正对纱线锭位的纱线检测处摄像，所述的纱线断头位置判别系统根据无线摄像头摄制的纱线检测处的实时图像与未断线时纱线检测处的标准图像比较判断纱线检测处纱线是否断头，并将判断结果信号输出到监控终端上。
更好地，固定件设置在吹吸风清洁机吹、吸风管道的内侧，在吹吸风清洁机往、复、往复行走时无线摄像头正对纱线锭位的断头处摄像。
更好地，固定件设置在吹吸风清洁机机架上，在吹吸风清洁机往、复、往复行走时无线摄像头正对纱线锭位的断头处摄像。

更好地，监控终端实时显示环锭细纱机的机位号、纱锭位置号和纱线断头图像或纱线断头指示信号。
更好地，所述纱锭位置号以6锭为一组。
更好地，所述监控终端为固定式显示器或手持式显示器。
本发明的有益效果是：监控人员可以坐在监控终端监控室里或手持无线监控器，实时监控纱线断头的位置、区域和断头数量分布，不需要人工不停地来回巡视，减少人员无功巡检，大大减少劳动强度，减少人力成本，且监控范围广，可依据断头数量分布情况集中处理，集中处理时无需停机，不影响人工操作和清洁，方便易行 。
