2. Description of the Related Art In a machine tool, the space for holding a workpiece and machining it is narrow because tools and other equipment are concentrated. Therefore, the loader robot is required to have a structure that allows the work to be attached to and detached from the machine tool in a limited space. On the other hand, some conventional industrial robots include a column and an operating arm that is connected to one end of the column and swings in a plane orthogonal to the axis of the column and is displaced in the axial direction of the column. However, in such a robot, when a gripping device for gripping a work is provided at the tip of the working arm and the work is attached / detached to / from the machine tool, the working arm performs two types of motions as described above. There is a risk that it may collide with tools and other equipment on the machine tool and damage them, or the working arm itself may be damaged.
