<p>A gripping device comprises: a gripping unit for gripping a work; a controller for controlling the gripping operation of the gripping unit; and contact sections attached to the gripping unit contacting the work, the contact sections being adapted to deform following the shape of the work, and to maintain the deformation. The gripping operation of the gripping unit presses the contact sections against the work to cause the contact sections to follow the outside of the work, and grips the work with the shape of the contact sections maintained. After predetermined number of times of gripping operation, the controller changes the positions of the contact points of the contact sections with the work when the work is gripped. As a result, different works having different shapes can be stably gripped and the lifetime of the contact sections can be extended to be longer than that of conventional products. The change, by the controller, in the positions of the points on the work with which the contact sections are in contact when the work is gripped is performed by shifting the contact sections in a plane vertical to the gripping direction.</p> |
