摘要： An apparatus for separating piled iron sheets one by one has a plurality of magnets arranged vertically with the same magnetic poles thereof facing each other. Magnetic fluxes generated from the magnets react with each other at a position between the magnets and flow horizontally and then vertically, with the result that opposite, vertically separating forces act on two superposed iron sheets.

摘要： A movable yoke-type lifting magnet device including a core having first and second ends and at least one yoke provided so as to be movable relative to the core in a vertical direction at each of the first and second ends of the core. A movable framework and a drive member for driving the movable framework relative to the core are further provided for lifting and lowering each yoke relative to the core. When the movable framework is driven upwards, the movable framework engages with each yoke and forcibly lifts each yoke. When the movable framework is driven downwards, the movable framework releases the yokes to allow them to move downwards by their own weight and to be gently brought into contact with a workpiece to be lifted.
摘要翻译：一种可移动轭形提升磁铁装置，包括具有第一端和第二端的芯，以及至少一个轭，其设置成在芯的第一和第二端中的每一个处沿垂直方向相对于芯移动。进一步提供用于相对于芯部驱动可移动框架的可动框架和驱动构件，用于相对于芯部提升和降低每个轭架。当可动框架向上驱动时，可动框架与每个轭架相接合并强制提升每个轭架。当可移动框架向下驱动时，可移动框架释放轭架，使它们能够通过自身的重量向下移动并且轻轻地与要被提升的工件接触。
