    • PROBLEM TO BE SOLVED: To surely detect that one of a plurality of metal wires 13 running in synchronization is broken, while offering simple and inexpensive construction. SOLUTION: Fixed tensile force is imparted to the metal wires 13 being running. The tensile force is reduced when one of the metal wires 13 is broken. As a result, the broken metal wire 13 is attracted to an electrode plate 41 by the magnetic force of a magnet 47 and put in contact therewith, and then a current is carried therein. The current is detected by a current detector 44 and the breakage of the metal wire 13 is thereby detected. The breakage of the metal wires 13, if existing in number, can be detected simply by the magnet 47 and the breakage detecting means 44 which are each installed. COPYRIGHT: (C)2005,JPO&NCIPI
    • 要解决的问题:为了确保检测到同步运行的多个金属丝13中的一个被破坏,同时提供简单和便宜的结构。 解决方案:固定的拉力被施加到正在运行的金属丝13上。 当金属线13之一断裂时,拉力减小。 结果,破损的金属线13被磁体47的磁力吸引到电极板41并与其接触,然后在其中承载电流。 由电流检测器44检测电流,从而检测出金属丝13的破损。 金属丝13的破损(如果存在数量)可以简单地由安装的磁体47和破损检测装置44来检测。 版权所有(C)2005,JPO&NCIPI

    • PURPOSE:To immediately detect the wire cut which is hardly detected by naked eyes by installing a detecting means for detecting the co-revolution or non-corevolution of a floating ring through a co-revolution mechanism, in a cable stranding machine. CONSTITUTION:When magnets 13... revolve with a guide roller 8 for guiding each core wire 2, a floating ring 14 receives a revolution torque in co-revolution an eddy current, and revolves by a certain angle against a springy member 20, and a light reflecting piece 19 set close to a window part 18 is hidden inside a cover 17. However, when the core wire 2 is damaged, and traveling is stopped, also the guide roller 8 stops, immediately, and the floating ring 14 is returned to the stop position by the springy member 20, and the light reflecting piece 19 on the outer peripheral surface is set close to the window part 18 of the cover 17, and the reflected light is received by an optical switch 23, and the generation of wire cut is detected.
    • 目的:通过在电缆绞合机中安装用于检测通过共旋转机构的浮环的共旋转或非卷绕的检测装置,立即检测出肉眼难以察觉的线切割。 构成:当磁体13 ...与用于引导每个芯线2的导向辊8一起旋转时,浮动环14接收涡流共旋转的旋转转矩,并相对于弹性构件20旋转一定角度,并且 靠近窗部18设置的光反射片19被隐藏在盖17内。然而,当芯线2损坏,行进停止时,引导辊8也立即停止,并且浮动环14返回 通过弹性构件20到停止位置,并且外周面上的光反射片19设置成靠近盖17的窗部18,并且反射光被光学开关23接收,并且产生 检测线切割。
