Description

卷绕机的横切装置
技术领域
本发明涉及一种用于卷绕幅面材料、优选幅面纤维材料或幅面无纺织物的卷绕机的横分装置或横切装置，所述横分装置或横切装置具有用于在结束卷绕过程后切开或分开幅面材料的横分机构或横切机构。
背景技术
在由织造纤维或非织造纤维制造织物幅时，所述织物幅在设备尾部借助卷绕轴卷绕在卷绕机上。如果材料卷达到限定的直径，则借助高速切割刀或备选地借助横分装置或横切装置切断织物幅并且将材料卷转移到等待位置或存储位置。所述横切装置通常包括旋转的刀具，所述刀具可以横向于织物幅移动并且切割所述织物幅。为了在切割织物幅时使所述织物幅不偏移，一压紧装置与所述刀具共同起作用。因而确保了织物幅强制地伸入旋转的刀具中进而被切断。
如果刀具的锐利程度下降，那么所述织物幅会积聚在旋转的刀具和压紧装置之间，从而由于产生的力而导致压紧装置断裂，这会导致横切装置的进一步损坏。
发明内容
因此，本发明的任务在于，这样改进横切装置，使得避免织物幅的积聚和所述装置的损坏。
本发明包括如下技术教导，即卷绕机的横切装置横向于织物幅的输送方向延伸和构造，对于织物幅的切割过程来说，所述横切装置从静止位置至少部分地枢转到织物幅的平面内。在此，横切装置包括至少一个刀具，该刀具设置成能沿着引导部正交于织物幅的输送方向移动。所述刀具在切割过程中与压紧装置持续地共同起作用。根据本发明，如果在刀具和压紧装置之间形成材料积聚，那么压紧装置构造成从运行位置转移到避让位置。由此，避免了压紧装置的断裂，这种断裂可能进一步导致横切装置损坏。
进一步的优点是所述刀具构造为旋转刀具并且压紧装置设置成围绕刀具的转动点能枢转。在材料积聚时，所述压紧装置通过枢转运动而避让由于横向于织物幅的移动运动而出现的力。
优选地，压紧装置设置在法兰上，所述法兰与平行于刀具设置的支撑部共同起作用。因此，压紧装置的枢转运动独立于刀具的旋转，从而所述刀具也可以在没有压紧装置的情况下而割断积聚的材料，或者在刀具不锋利的情况下，将所述织物幅无切断地引导经过刀具。因此，避免了材料进一步积聚。
支撑部具有圆弧状的凹槽，法兰的引导元件进入所述凹槽中。因此，限制法兰的枢转运动进而限制压紧装置的枢转运动。法兰具有弹簧加载的止动装置，所述止动装置使法兰和压紧装置保持在运行位置中，由此可以在材料强度和材料厚度波动时避免压紧装置过早地枢转到避让位置中。
优选地，止动装置的弹簧载荷是可调节的，从而所述枢转运动可以适应于(厚度、材料等等)不同的织物幅。
仅在超过弹簧力时才触发止动装置且将法兰和压紧装置枢转到避让位置中。
优选地，法兰与压紧装置可以构造成能手动地或自动地从避让位置枢转到运行位置。从避让位置自动地以及借助于控制杆手动地枢转到操作位置防止操作者在刀刃处受伤。
另一种自动化可以借助传感器实现，所述传感器确定压紧装置和/或法兰在支撑部的部分周面上的位置。因此，可以警示操作者和/或必要时关闭机器。
附图说明
接下来结合对本发明的优选实施例的描述、借助于附图进一步示出其他改进本发明的措施。其中：
图1示出具有横切装置的示例性的卷绕机；
图2示出根据本发明的横切装置的第一细节视图；
图3示出图2的放大的细节视图；
图4示出根据本发明的横切装置的另一个细节视图；
图5示出根据本发明的横切装置的另一个细节视图；
图6示出止动装置的细节视图。
具体实施方式
图1示出一种具有根据本发明的横切装置10的示例性的卷绕机1。所述卷绕机1以喂料区域2位于将纤维制造成无纺布或无纺织物产品的设备的尾部。未进一步标明的织物幅通过喂料区域2进入到卷绕机1中并且在卷绕轴4上卷绕成未示出的卷装物。卷绕轴4呈现在储备位置中。在辅助支持卷绕过程的接触辊5的上方显示有横切装置10，该横切装置在接下来的附图中详细描述。完成的卷装物在与剩余的织物幅分割后经由输出区域3被输送到半成品仓库或成品仓库。
图2和图3在放大的视图中示出所述横切装置10，该横切装置横跨接触辊5并且借助可转动地支承的法兰11能围绕所述接触辊5的转动轴线(沿箭头)枢转到张紧的织物幅上。在该视图中，所述横切装置10位于等待位置，直到卷装物卷绕完毕。在达到预定的卷绕长度后，所述横切装置10枢转到织物幅的平面中，其中，刀具13侧向地位于织物幅之外并且处于织物幅的平面之下。通过切割运动，所述刀具13侧向移入织物幅并将其切割。于是，楔形的压紧装置14位于织物幅的平面之上，从而所述织物幅位于刀具13和压紧装置14之间并且通过刀具旋转到织物幅上且横向运动来切割所述织物幅。在所述横切装置10的内部设置有线性的引导部12，沿着所述线性的引导部横跨织物幅驱动地引导所述刀具13并且切割织物幅。所述刀具13以与接触辊5的纵轴线成30°至60°角设置，其中，为了实现相对于卷绕方向尽可能成直角的切割，上述角度的大小还与卷绕速度相关。
图4示出横切装置10的一部分的放大视图，其中，前侧和后侧的挡板15被取下。刀具13构造为旋转刀具，通过马达式的或气动的驱动装置17使所述旋转刀具旋转。刀具13可转动地支承在机架16上，所述驱动装置17也抗扭地设置在所述机架上。在刀具13和驱动装置17之间设置有用于压紧装置14的支撑部18，所述压紧装置可以至少部分地围绕该支撑部18枢转。为此，所述压紧装置14紧固在法兰20上，利用这里不可见的引导元件21在所述支撑部18的凹槽19中在圆弧形轨道上引导所述法兰。在运行位置中，即刀具13切割织物幅时，压紧装置14则位于前面提到的上方的位置中，其中，所述法兰20连同引导元件21位于凹槽19的上方的止挡处。压紧装置14与法兰20借助未示出的弹性元件保持在该位置中。所述弹性元件构造成可调节的，以便可以改变针对该位置的止动力。根据现有技术，钝的刀具13导致材料积聚，由此经常导致压紧装置14的断裂。
根据本发明，在材料积聚时所述压紧装置14和法兰20可以枢转到下方的避让位置(图5)，从而不损坏横切装置10。在此，弹性元件的力被克服并且法兰20和压紧装置14沿着圆弧设置的凹槽19移动到下边的避让位置。
在清除旋转刀具13和压紧装置14之间的积聚的材料之后，法兰20和压紧装置14可以借助手柄23和控制杆22手动地枢转到运行位置(图4)。手柄23和控制杆22不是固定地安装，而是在避让位置中插入到法兰的孔中。凹槽19这样构造，使得压紧装置14和法兰20可以从与刀具13的相作用处枢转大约90°，这在该视图中以顺时针沿材料行进方向实现。
优选地，压紧装置14或法兰20的位置可以借助传感器监控，从而在这两个构件枢转时向卷绕机1的控制装置传递信号。这可以为操作者触发警示信号或使卷绕机自动地停机。代替借助手柄23和控制杆22手动地从避让位置复位到运行位置，所述法兰20和压紧装置14也可以自动地复位。为此规定，刀具10停止并且机架16沿着引导部12再次移动到织物幅之外的法兰11处的等待位置中。
图6示出穿过横切装置的剖视图，其中，刀具13平行于支撑部18设置。在该图示中可以看到引导元件21，其沿着凹槽引导法兰20。在法兰20上方可以看到压紧装置14，所述压紧装置与刀具13在该视图中形成小的垂直的间隙。在法兰20上构造有示例性的止动元件24，所述止动元件可以作为具有圆锥形的或倒圆的尖端的弹簧加载的销与凹部25共同作用。所述止动元件24可以根据通过弹簧力预定义的分离力从所述凹部25压出，从而法兰20和压紧装置14可以沿着凹槽19枢转到避让位置。在本发明的范围内当然也可以使用备选的止动装置。
