Patent ID: 8888435

Claim:
An industrial robot comprising: a first hand and a second hand, both configured to transport objects loaded thereon; an arm to which said first hand and said second hand are rotatably joined; and a main unit which a base end portion of said arm is rotatable joined; wherein a base end portion of said first hand and a base end portion of said second hand are joined to a front end portion of said arm; wherein said first hand and said second hand are independently rotatable with respect to said arm and also rotatable about a common center of rotation with respect to said arm in the from a top-bottom direction; wherein each of the first and second hands is formed being bent at a bending section in the view from the top-bottom direction; wherein the first hand and second hand are formed to have line symmetry about a predetermined imaginary line passing through said center of rotation in the view from the top-bottom direction; wherein the industrial robot is: configured to take out said objects to be transported from a first arrangement location, in which said objects to be transported are stacked up in the top-bottom direction while a front end side of said first hand and a front end side of said second hand are overlapped with each other ire the top-bottom direction; and/or configured to carry said objects to be transported into said first arrangement location while the front end side of said first hand and the front end side of said second hand are overlapped with each other the top-bottom direction; wherein the industrial robot is: configured to take out said objects to be transported from a second arrangement location, in which said objects to be transported are arranged so they are not overlapping with each other in the top-bottom direction while the front end side of said first hand and the front end side of said second hand are not overlapped with each other; and/or configured to carry said objects to be transported into said second arrangement location while the front end side of said first hand and the front end side of said second hand are not overlapped with each other; and wherein said first hand and said second hand are formed such that the front end side of said first hand and the front end side of said second hand are kept overlapped crossing over each other during a time of linearly transporting said objects to be transported with respect to said first arrangement location.
