Lifting Magnet System For Transferring Sheet Metal To Laser Device

The present invention relates to a lifting magnet system for transferring an iron plate to a laser device, and more particularly, to a laser device, such as a laser cutting device, to stably transport an iron plate as a workpiece to a laser device. It relates to a lifting magnet system for

In general, a hoist is a device that moves to a desired position by hoisting and unloading a heavy object while moving in the front-rear and left-right directions along a rail installed on the ceiling. A wire drum is built into the body of such a hoist, a wire is wound around the wire drum, and a hook is installed at one end of the wire. The wire drum unwinds or winds the wire and moves the hook up and down. When the heavy object is connected to the hook, it can be hoisted and unloaded by a hoist and moved to a desired position.

Meanwhile, the weight may be made of metal. When a heavy object is formed in a plate shape or a rod shape, it is difficult to connect to the hook of the hoist. In order to connect the hook to the plate-shaped or rod-shaped metal weight, a separate configuration is required. In this case, a separate configuration is made in the form of a strap, etc., and is formed in a form to wrap a heavy metal object. In addition, with the center of the metal weight being considered, the hook of the hoist should be positioned with respect to the metal weight. For this reason, in order to move the plate-shaped or rod-shaped metal weight using the hoist, it takes a considerable amount of time to connect the hoist and the metal weight. In addition, a configuration having the shape of a strap or the like may damage the surface of the heavy metal in order to be firmly coupled with the heavy metal. Therefore, a general hoist moves a heavy metal, while reducing the quality of the heavy metal while wasting time in connection with the heavy metal.

On the other hand, the above-mentioned background technology is technical information that the inventor possessed for the purpose of derivation of the present invention or acquired during the derivation process of the present invention, and it cannot be said that it is necessarily known technology disclosed to the general public before the filing of the present invention. .
