Abstract: A vacuum pad includes a support member that includes a vacuum passage and a bellows that is attached to the support member, and the cover body includes a cylindrical body portion, an attaching portion projecting from one end of the body portion, and a flange portion projecting radially outward from another end of the body portion. The cover body covers the outside of the bellows when the bellows contracts and holds a workpiece by suction.

Abstract: A suction device includes an adapter having in the interior thereof a supply passage to which a negative pressure fluid is supplied, a bellows connected to a distal end of the adapter, and a pad member disposed at a distal end of the bellows and to which a workpiece is attracted under suction. In addition, the suction device attracts the workpiece under suction by a negative pressure fluid which is supplied to the pad member through the supply passage and the bellows. An attachment which is capable of being tilted with respect to the axis of the bellows is provided in the interior of the bellows. In the attachment, a main body portion thereof is disposed in facing relation to a suction surface of a skirt, and a shaft portion is inserted into the supply passage at a time that the workpiece is attracted under suction.

Abstract: A suction device includes an adapter having a supply passage to which a negative pressure fluid is supplied, a bellows connected to a lower end of the adapter, and a pad member formed at the distal end of the bellows. The pad member has plural first and second ribs on a suction surface that attracts a workpiece under suction. The first ribs are disposed on an outer circumferential side of an attachment provided in the center of the pad member and extend toward the outer circumferential side. The second ribs are provided on an outer circumferential side of the first ribs, and are disposed in a circumferentially offset manner with respect to the first ribs. Additionally, between the respective first ribs which are disposed alongside one another in the circumferential direction of a skirt, supply paths are formed to which the negative pressure fluid is supplied from the attachment.
