Patent number: 11027388Abstract: A machining system comprises a machining device that machines a workpiece, a set-up station with which pallet workpiece attachment/detachment is carried out, and a pallet conveyance device that conveys the pallet between the machining device and the set-up station. A partially cylindrical operator door, which can rotate around a set-up table on which the pallet is mounted, includes a partially cylindrical outer door and a partially cylindrical inner door which rotate following coaxial circular trajectories of different radii. The set-up station is provided with an interlocking mechanism that causes the outer door and the inner door to rotate in an interlocked manner so that a shielded state is constantly maintained between the operator side and the pallet conveyance device side.Type: GrantFiled: September 9, 2016Date of Patent: June 8, 2021Assignee: MAKINO J CO., LTD.Inventors: Takudai Maenosono, Takahiro Yoshida, Nobuhiro Uchida, Yuichi Aoyama
