A tool magazine apparatus including:
- a magazine body consisting of a frame, and a plurality of front racks and rear racks that are detachably attached to the frame with a longitudinal direction of the both front and rear racks directed in an identical direction and are configured to hold a plurality of tools such that a direction of a tool axis of each tool is directed in a Z-axis direction which is a spindle axis direction;
- and a tool transfer device that is disposed on the magazine body so as to move in the Z-axis direction and in the longitudinal direction of the both front and rear racks and is configured to take out the tool from the both front and rear racks and attach the tool to the both front and rear racks, each of the front racks being provided at intervals in the longitudinal direction thereof with a plurality of tool holding grippers that are open rearward and are configured to hold the tools, each of the rear racks being provided at intervals in the longitudinal direction thereof with a plurality of tool holding grippers that are open frontward and are configured to hold the tools, and the both front and rear racks being respectively arranged at intervals in the Z-axis direction, wherein
- the tool magazine apparatus comprises:
- a tool standby pot configured to hold the tool to be attached to a spindle of a machine tool and the tool to be removed from the spindle, with the direction of the tool axis directed in the Z-axis direction;
- and an intra-magazine tool change device that is disposed on the magazine body so as to move in the Z-axis direction relative to the tool standby pot and is configured to deliver the tool between the tool standby pot and the tool transfer device, and
- the tool transfer device comprises:
- a moving body that is disposed between the front racks and the rear racks and is configured to move in the Z-axis direction and in the longitudinal direction of the both front and rear racks;
- a base that is disposed on the moving body so as to be rotatable around an axis extending in the Z-axis direction;
- a transfer gripper that is attached to the base so as to be movable in a plane orthogonal to the Z-axis direction and is configured to hold the tool with the direction of the tool axis directed in the Z-axis direction;
- and an actuator that is attached to the base and is configured to cause the transfer gripper to move in the plane so as to cause the transfer gripper to move to a tool attachment/detachment position to/from one of the tool holding grippers.
