Abstract

本发明涉及一种用来测知行进中的长丝***的方法和装置，其中，长丝穿过一叉形导丝元件。它被长丝***部位从起始位置上推开，这时通过该运动触发一信号。在导丝元件运动期间，让带有***部位的长丝继续行进，然后退回到其起始位置。

Description

用来测知行进中的长丝***的装置
技术领域
本发明涉及一种用来测知行进中的长丝***的装置。
背景技术
已经采用过一种用来测知***的检测器，在该检测器中长丝或纤维束通过一两块板之间的缝隙，其中一块板可摆动地支承。这里缝隙通过两块板平行的棱边围成；长丝的***使动板向下回转，这个回转运动通过一检测器测知。这种***相当不灵敏，另外还有一个缺点，即，***部位卡在板的棱边上，这时经常造成长丝断裂。
由于上油剂的堆积造成的粘结使这种已知***在运行时更不灵敏，并需要比较经常地清洗。为此必须不利地中断纺丝运行。
发明内容
本发明的目的是，创造一种补救办法，方便和运行可靠地测知运行中的长丝或纤维束的***。这里***的长丝应该毫无问题地继续行进，就象特别对于纺丝设备有利的那样。按照本发明这个目的通过这样的方式来实现，即，长丝穿过一叉形导丝元件，该导丝元件被长丝***从一起始位置推离，这时通过此运动触发一信号，这个反映运动的信号可以是机械、光学、声学、电学或电磁性质的。
具体地说，本发明提供一种用来测知行进中的长丝或纤维束上的***部位的装置，包括一个在一端固定的叉形导丝元件，此导丝元件可向长丝或纤维束行进方向偏转并可通过弹簧力回复到起始位置，长丝或纤维束穿过该导丝元件的宽度可调的缝隙，该导丝元件与一运动检测器连接，其特征为：所述导丝元件固定在一转轴上；并且所述缝隙背向转轴的段做成扩张的结构，而在朝向转轴的段内是平行的。
导丝元件例如和一复位弹簧共同工作，使得在它被长丝***带动之后，便回复到其起始位置。
附图说明
借助于附图对本方法和装置可能的方案加以说明。附图表示：
图1  以示意图表示装置沿图2中I-I线的水平剖视图，和
图2  装置沿图1中II-II线的垂直剖视图。
具体实施方式
用来测知长丝(2)***的装置安装在例如属于纺丝设备的一垂直壁(1)上。在图1和2中从这样的情况出发，即，长丝(2)从上向下沿箭头(3)方向垂直运动，例如通过一牵引装置。
长线(2)穿过一叉形导丝元件(4)，在这里是2个销子(4a)和(4b)之间。可以是陶瓷覆层的销子具有一相互平行的部分和一前端的扩张部分，参见图1。销子(4a)和(4b)相互的距离可以做成可调的，但是在这图中未表示出来。
导丝元件(4)固定在一水平轴(5)上，该水平轴可回转地支承在一壳体(6)内。导丝元件(4)向外穿过壳体(6)上的开口(6a)。一信号臂与轴(5)相连，所述信号臂通过复位弹簧(8)拉向靠在一位置固定的止挡(9)上的起始位置或静止位置，参见图2。信号臂(7)穿过垂直壁(1)上的一个开口(1a)。
如果行进中的长丝(2)有一个***，在短时间内便通过***在导丝元件(4)上作用一个力，它使导丝元件向下偏转，如图2中虚线所示。由于销子(4a)和(4b)在前部的距离扩大，在较短的回转运动以后导丝元件(4)便将长丝重新释放，因此长丝可以不受干扰地继续行进。同时导丝元件，通过弹簧力牵引，重新回到起始位置。如果长丝(2)来自一纺丝设备，在它到达导丝元件(4)时便已经冷却，并不再是或几乎不再是塑性的。
结构做成这样，使得不再可能特别是由于上油剂的堆积导致粘结和运行故障。这通过用护罩罩起来的轴承和完全封闭的壳体达到。
在导丝元件(4)短时间回转时，信号臂(7)也向上回转，如图2中虚线所示。这时信号臂向背离检测器(10)作用区的方向运动，所述检测器位置固定地固定。检测器以已知的方式对信号臂(7)的这个运动发出信号，并使例如操作者注意这个操作。现在操作者需要采取必要的措施，例如对纺丝设备进行清洗工作。为了能够改变弹簧(8)的复位力，信号臂(7)具有多个孔眼(11)，弹簧(8)可以可选择地挂在这些孔眼内。此外弹簧(8)可以与一长度可调的***，例如一螺纹销(8a)连接，参见图2，以便可以无级地调整弹簧力。
