Abstract: A conveyance device (100) comprises: a carriage (10); a support column (20); a lifting device (30) that moves in the vertical direction along the support column (20); and a load platform (90) that is moved in the vertical direction by the lifting device (30). The lifting device (30) includes an upper guide (40), a lower guide (50), and a linking member (60) for linking an upper member (41) and a lower member (51) together. The upper guide (40) includes: a first wheel (42) that rolls on a rear surface (22) of the support column (20); and the upper member (41) which supports the first wheel (42). The lower guide (50) includes: a second wheel (52) that rolls on a front surface (21) of the support column (20); and the lower member (51) which supports the second wheel (52), the lower guide being disposed below the upper guide (40). The load platform (90) is disposed in front of the second wheel (52), and is linked to front side and rear side portions of the linking member (60).

Abstract: 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.
