<p>PURPOSE:To provide a compact and simple chucking device by providing an attracting plate which can be moved up and down in association with energization and deenergization of an electromagnet and a chucking mechanism adapted to be driven in association with the upward motion of the suction plate, in the lower section of the electromagnet. CONSTITUTION:An electromagnet 1 is suspended from a trolley or the like through the intermediary of an elevating device 2. When an attracting plate 11 is moved downward, relative to the electromagnet 1, a link 10 is turned to a position near to its horizontal position so that chucking pawls 7 are rotated about a shaft 8 and are therefore opened. In this condition, the chuck pawls 7 are lowered by the elevating device 2 from a position above an article P to be chucked, and when the electromagnet 1 is energized, the attracting plate 11 is attracted by the electromagnet 1 so as to be moved upward. The chuck pawls 7 is rotated about he shaft 8 so hat they are closed to chuck he article P. Thereafter, the article P is elevated by the elevating device 1, and is then moved to a predetermined position where it is lowered. Thereafter, when the electromagnet 1 is deenergized, he attracting plate 11 is lowered by its dead weight away from the electromagnet 1, and accordingly, the chucking pawls 7 are rotated outward so as to be opened to release the article P.</p> |
