Patent number: 9904259Abstract: A plate member reversing system adapted for sequentially reversing and transferring a plurality of plate members, includes a second delta robot, a reversing device and a second transfer device. The second delta robot is configured such that it sequentially holds the plate members and transfers and places them onto the reversing device. The reversing device, onto which the plate member is transferred and placed in a horizontal position by the second delta robot, is configured such that, while the transferred and placed plate member is being held by application of suction with its upper surface in an open state, it reverses the upper and the lower surfaces of the plate member. In addition, the second transfer device receives the reversed plate member from the reversing device and transfers it in a reversed state and in a horizontal position.Type: GrantFiled: March 30, 2012Date of Patent: February 27, 2018Assignee: KAWASAKI JUKOGYO KABUSHIKI KAISHAInventors: Kenji Bando, Toshihiko Miyazaki, Shuhei Kuraoka
