Patent number: 10446432Abstract: A conveyance system includes a conveyance chamber including a second side wall opposite to a first side wall in a depth direction of the conveyance chamber. A robot is disposed in the conveyance chamber. The robot includes a body, a first arm, a second aim, and a hand. The body is disposed between the second side wall and a reference position in the depth direction. A second leading end of the second arm is positioned between a restricted position and the reference position in the depth direction when a first inter-axis direction and a second inter-axis direction are substantially perpendicular to the first side wall. A controller is connected to the robot to control the robot to limit entrance into an area between the first side wall and the restricted position in the depth direction.Type: GrantFiled: April 4, 2017Date of Patent: October 15, 2019Assignee: KABUSHIKI KAISHA YASKAWA DENKIInventors: Hiroki Sanemasa, Daisuke Shin, Hisaya Inoue, Ryosuke Watanabe

Patent number: 8833196Abstract: A gear unit includes an inner shaft and an outer shaft concentrically arranged to make up two concentric output shafts; and a first and a second input shaft extending in a direction orthogonal to the output shafts and operatively connected to the inner shaft and the outer shaft, respectively. The inner shaft includes an inner gear attached thereto and the outer shaft includes an outer gear attached thereto. The inner gear and the outer gear are arranged in a mutually-opposing relationship. The first input shaft and the second input shaft are spaced apart from each other by a specified distance along an axial direction of the output shafts. The first input shaft includes a first input gear meshing with the inner gear and the second input shaft includes a second input gear meshing with the outer gear.Type: GrantFiled: September 7, 2012Date of Patent: September 16, 2014Assignee: Kabushiki Kaisha Yaskawa DenkiInventors: Masatoshi Furuichi, Hiroki Sanemasa
