Tool transport device

A tool transport device transporting a tool body between a machine tool including a tool magazine holding a plurality of tool bodies and a tool storage device storing a plurality of tool bodies, the tool body comprising a tool and a tubular member having the tool inserted therein, wherein the tool transport device comprises:

• a moving device having a moving platform and configured to move the moving platform to a working position set for the tool magazine and to a working position set for the tool storage device;
• a tool attachment/detachment robot and a tool holding member arranged on the moving platform;
• and
• a controller configured to control operations of the moving device and tool attachment/detachment robot;
• and
• the tool attachment/detachment robot is configured to transport the tool body by gripping an outer peripheral portion of the tubular member;
• the tool holding member is disposed within an operating area of the tool attachment/detachment robot and has a cutout-shaped holding portion formed on a side face thereof, the holding portion having:
• an opening,
• at least two parallel inner surfaces spaced apart in a vertical direction and facing each other, and
• a far side inner surface located on a far side of the opening and connecting the two parallel inner surfaces in the vertical direction;
• the holding portion is configured such that the two inner surfaces thereof are able to engage with two parallel engagement surfaces formed in a direction perpendicular to an axis of the tubular member on an outer peripheral portion of the tubular member;
• and
• the holding portion is formed on the tool holding member such that a plane parallel to an arranged direction of the two inner surfaces and orthogonal to both the two inner surfaces and the far side inner surface is inclined backward in a direction away from the tool attachment/detachment robot;
• and
• the holding portion is provided such that the two inner surfaces are inclined with the opening facing upward with respect to a horizontal line in the plane parallel to the arranged direction of the two inner surfaces and orthogonal to both the two inner surfaces and the far side inner surface.
