Description

一种织机找纬机构及找纬方法
技术领域
本发明涉及一种织机找纬机构，具体说是一种在织机纬向故障断纬纱停车后 无需采用分离脱开复位啮合机构（俗称找纬箱）就能使织机的开口、选纬、送经、 卷取回到刚才断纬的那一纬的找纬机构及找纬方法。
背景技术
织机的找纬机构是一种在织机遇纬向断纬故障停车后找出并回到断纬前刚 才的织机状态的机构， 织机有了找纬机构可实现精确对纬， 消除织物的断纬稀密 横档，提高织物的品质， 而传统的找纬机构是在织机主机的主轴和经纱开口机构 之间的传动中另设有专门的能分离脱开、 复位啮合的机构 （俗称找纬箱）， 当织 机断纬时控制电箱控制专设的动力机构使经纱开口机构脱开主机倒转一纬的量 后再复位啮合与主机复位，此过程虽然可实现找纬功能，但其另设了找纬动力机 构和分离脱开、 复位啮合机构 （俗称找纬箱）机械零件较多， 易磨损损坏， 特别 是当经纱开口机构大起大落反向力大的时候，需很大的找纬动力和倒车箱结合齿 机构来实现， 往往造成找纬找不动， 不能复位等故障， 尤其是给多针数大提花经 纱开口机构的用户带来很大的难题和烦恼， 增加了生产使用成本。
本发明采用了一种结构简单、性能稳定实用的传动和控制方式， 很好的解决 了此难题。由于在主机主轴和经纱开口机构之间传动中不另设专门的动力机构和 分离脱开复位啮合的传动机构 （俗称找纬箱）， 而是直接经同步带和同步轮或链 轮和链条或换向齿轮和轴带动由电子信号控制的开口机构和选纬机构，结构更简 单传动更稳定， 和织机正常织造一样， 能有效消除磨损和减少维修量， 减少织机 生产成本和使用成本。
发明内容
为了克服现有技术的不足，本发明采用由控制电箱控制织机主机通过同步带 配同步轮或链轮配链条或换向齿轮配轴直接传动由电子信号控制的经纱开口机 构和由电子信号控制的纬纱选纬机构运转，同时在此过程中控制电箱切换两机构 电子信号、控制数控送经机构和数控卷取机构反向随动、数控防钢筘打纬机构张 筘或位移织口防止重复打纬。

所述由电子信号控制的经纱开口机构是电子提花机或电子多臂机通过联接 件带动经纱运动的机构。
所述主电机、减速传动机构、离合制动机构这几部分也可以由变速的、带快 速制动和起动功能的电机替代。
所述防纬纱入剑头机构是在织机上设有抬起纬线脱开送纬的抬纬机构，或采 用独立电机的选纬机构缩回选色杆来防止找纬过程中纬纱不进入引纬剑头。
所述数控送经和数控卷取跟随主机的信号采集机构和找纬关键点信号机构， 可以是二合一的机构经控制电箱处理信号后分别使用；两种机构各自可以采用编 码器也可以采用信号凸配合传感器相结合的机构。
所述织机找纬机构的找纬方法：当织机的控制电箱通过纬纱检测传感器检测 到纬向故障控制织机断纬停车至找纬关键点角度处后，控制电箱控制主电机通过 减速传动机构、离合制动机构、织机主轴经同步带配同步轮或链轮配链条或换向 齿轮配立轴直接传动由电子信号控制的经纱开口机构和电子信号控制的纬纱选 纬机构自找纬关键点角度处正转至下一纬找纬关键点角度处静止来实现找纬，同 时此过程中控制电箱控制经纱开口机构的电子信号反向切换、纬纱选纬机构的电 子信号反向切换、数控送经和数控卷取作相对正常织造时方向的反方向运动、数 控防钢筘打纬机构张筘或位移织口、 抬纬机构工作或选纬杆缩回防纬纱入剑头， 找纬结束后恢复正常状态。
所述找纬关键点角度设置于织机引纬机构的引纬剑头位于经纱织口外的角 度区间或喷气织机喷嘴喷纬纱的角度区间外，信号发生器对应的关键点信号传感 器发出关键点信号至控制电箱。
在找纬过程中数控防钢筘打纬机构采用控制电箱控制数控起毛圈活筘打纬 机构将活筘张开一定角度方式；或采用控制电箱控制移动的前胸梁和后圆棍同步 运动使织口远离钢筘打纬点方式；或采用控制电箱控制卷取和送经在找纬过程中 打纬之前向正常卷取方向同步卷取一定的量完成织口位移方式，使织机在打纬点 时钢筘打不到纬纱， 找纬结束后各自恢复至正常状态。
本发明找纬机构传动结构简单、性能稳定、方法新颖科学， 能消除断纬稀密 档，尤其是解决了配多针数大提花龙头开口机构的织机找纬时找纬箱带不动开口 机构和找纬箱不稳定、易损坏的难题，在找纬过程中开口机构的信号选择机构正 转解决了信号选择机构反转选择占用角度小、时间短、易产生开口执行机构多拉 少提的难题， 并消除了影响找纬效果的多次空打纬现象。
