[0027] The tool magazine 100 further includes a setup station 200. The setup station 200 is a device for setting up the tools T stored in the tool magazine 100 (tool storage section 110).

[0028] The tool magazine 100 (the setup station 200) has a rotating body 230. The rotating body 230 is rotatable about a predetermined axis 510 extending in the Y-axis direction (up-down direction). The rotating body 230 is manually rotated about the predetermined axis 510.

[0029] The rotating body 230 includes a shaft 220, a base member 310 (310A, 310B), and a rotating cover 231 (231A, 231B).

[0030] The shaft 220 extends in the Y-axis direction along a predetermined axis 510. The shaft 220 is supported so as to be rotatable about the predetermined axis 510.

[0031] The base member 310 is made of a pillar extending in the Y-axis direction. When cut along the X-axis-Z-axis plane, the base member 310 has a rectangular cross section. The base member 310 is provided at a position away from the specified axis 510 (shaft 220) on the radially outer side of the specified axis 510.

[0032] The base member 310A is provided at one end of the rotating body 230 radially outside the specified axis 510. The base member 310B is provided at the other end of the rotating body 230 radially outside the specified axis 510. The distance between the specified axis 510 and the base member 310A in the radial direction of the specified axis 510 is the same as the distance between the specified axis 510 and the base member 310B in the radial direction of the specified axis 510. The base member 310A and the base member 310B form the framework of the rotating body 230 at one end and the other end of the rotating body 230 radially outside the specified axis 510, respectively.

[0033] The swivel cover 231 is composed of a cover body arranged parallel to the Y-axis direction. The swivel cover 231 is attached to the base member 310. The swivel cover 231A and the swivel cover 231B face each other across the shaft 220. The swivel cover 231A and the swivel cover 231B are attached to the base member 310A at one end of the swivel body 230 radially outward from the specified axis 510. The swivel cover 231A and the swivel cover 231B are attached to the base member 310B at the other end of the swivel body 230 radially outward from the specified axis 510.

[0034] The swivel cover 231 separates a space in which a tool T held by a first setup unit 260A (described later) is placed, from a space in which a tool T held by a second setup unit 260B (described later) is placed.

[0035] The rotating body 230 further includes a first setup unit 260A and a second setup unit 260B. Each of the first setup unit 260A and the second setup unit 260B is capable of holding a plurality of tools T.

[0036] The first setup unit 260A is provided at one end of the rotating body 230 on the radially outer side of the predetermined axis 510. The tool T held by the first setup unit 260A faces the rotating cover 231A.

[0037] The second setup unit 260B is provided at the other end of the rotating body 230 radially outward of the specified axis 510. The second setup unit 260B is provided at a position shifted 180° from the first setup unit 260A around the specified axis 510. The tool T held by the second setup unit 260B faces the rotating cover 231B.

[0038] The setup station 200 further includes a lock pin 240 and a detection unit 245. The lock pin 240 is provided so as to be insertable into and removable from the revolving body 230 by an actuator such as an air cylinder. When the lock pin 240 is inserted into the revolving body 230, the revolving movement of the revolving body 230 about the predetermined axis 510 is restricted, and when the lock pin 240 is removed from the revolving body 230, the revolving movement of the revolving body 230 about the predetermined axis 510 is permitted.

[0039] The detection unit 245 is configured to be able to detect the insertion and removal of the lock pin 240 into the revolving body 230. When the detection unit 245 detects the insertion of the lock pin 240 into the revolving body 230, the machine tool 10 allows the operation of the tool transportation device 130, and when the detection unit 245 detects the removal of the lock pin 240 from the revolving body 230, the machine tool 10 restricts the operation of the tool transportation device 130.

[0040] 1, the first setup unit 260A is disposed in a space outside the magazine space 145, and the second setup unit 260B is disposed in the magazine space 145. The rotating cover 231, together with the magazine cover 140, defines the magazine space 145. In the second setup unit 260B, a tool rack 320 (described later) is disposed on the same X-Y plane as the tool rack 115 in the tool storage section 110. The lock pin 240 is inserted into the rotating body 230.

[0041] In this case, outside the magazine space 145, a worker performs setup work such as removing a used tool T from the first setup unit 260A and mounting a new tool T to the first setup unit 260A. Meanwhile, in the magazine space 145, the tool transport device 130 switches tools between the second setup unit 260B, to which the new tool T has been mounted, and the tool storage section 110.

[0042] The operator removes the lock pin 240 from the rotating body 230 by operating an operation unit such as an operation button (not shown). The operator applies a force to the rotating body 230 in the circumferential direction of the specified axis 510, thereby rotating the rotating body 230 180° around the specified axis 510. The operator inserts the lock pin 240 into the rotating body 230 by operating an operation unit such as an operation button (not shown). As a result, the first setup unit 260A is placed in the magazine space 145, and the second setup unit 260B is placed in the space outside the magazine space 145. The operator can perform setup work for the tool T in the second setup unit 260B.

[0043] 1, the machine tool 10 further has an ATC shutter 70. An opening 82 is provided in a cover body 80 that defines the machining area 20. The opening 82 is open between the tool holding device 60 installed at the tool standby position K and the tool spindle 30 positioned at the tool changing position J. The ATC shutter 70 is provided in the opening 82. The ATC shutter 70 is operable by an actuator such as an air cylinder (not shown) between an open position where the opening 82 is opened and a closed position where the opening 82 is closed.

[0044] The ATC shutter 70 is operated from the closed position to the open position when tool change by the automatic tool changer 40 starts, and is operated from the open position to the closed position when tool change by the automatic tool changer 40 is completed. When tool change by the automatic tool changer 40 starts, the machine tool 10 allows the operation of the ATC shutter 70 if the detection unit 245 detects that the lock pin 240 has been inserted into the revolving body 230, and restricts the operation of the ATC shutter 70 if the detection unit 245 detects that the lock pin 240 has been removed from the revolving body 230.

[0045] With this configuration, the opening operation of the ATC shutter 70 is not permitted unless each of the setup units 260, the first setup unit 260A and the second setup unit 260B, is located at a predetermined position inside or outside the magazine internal space 145. In addition, when each of the setup units 260, the first setup unit 260A and the second setup unit 260B, is in the middle of rotating about the predetermined axis 510 or is stopped in the middle of rotating, the opening operation of the ATC shutter 70 is not permitted.

[0076] FIG. 8 is a diagram showing an example of the flow of tool transfer and tool exchange between the tool spindle and the tool magazine.

[0077] 1 and 8, in an initial state, after automatic tool exchange is performed on the tool spindle 30, the ATC shutter 70 performs a closing operation (S201). The tool spindle 30 holds a tool A, and the tool holding device 60 holds a used tool B.

[0078] After the ATC shutter 70 is closed, in the machining area 20, the tool spindle 30 starts machining the workpiece using the tool A (S101), and at the tool standby position K outside the machining area 20, the tool B is transferred from the tool holding device 60 to the tool transport device 130 (S301). In step S301, the tool transport device 130 holds the tool B held by the tool holding device 60 by its gripping portion, and the tool holding device 60 releases its hold on the tool B.

[0079] Next, the tool transport device 130 moves from the tool standby position K to the tool rack 115 in which the tool B is to be stored (S302). Next, the tool transport device 130 carries the tool B into the tool rack 115 (S303). In this step, the tool transport device 130 causes the tool B held by the gripper to enter the tool rack 115 and releases the grip of the tool B by the gripper. Next, the tool transport device 130 moves to the tool rack 115 in which the tool C to be used in the next process is stored (S304). Next, the tool transport device 130 carries the tool C out from the tool rack 115 (S305). In this step, the tool transport device 130 causes the gripper to enter toward the tool rack 115 and grips the tool C by the gripper.

[0080] Next, the tool transporting device 130 moves from the tool rack 115 toward the tool standby position K (S306). Next, the tool transporting device 130 delivers the tool C to the tool holding device 60 (S307). In this step, the tool transporting device 130 causes the tool C held by the gripping unit to enter the tool holding device 60, releases the gripping of the tool C by the gripping unit, and the tool holding device 60 holds the tool C.

[0081] The tool spindle 30 completes the workpiece machining using the tool A (S102). The tool spindle 30 moves to a tool exchange position J in the machining area 20. Typically, the step of S307 is completed before the step of S102. After the step of S102, the ATC shutter 70 performs an opening operation (S202). Next, the automatic tool changer 40 exchanges tools between the tool spindle 30 and the tool holding device 60 (S203). With this step, the tool spindle 30 holds the tool C, and the tool holding device 60 holds the used tool A. Next, the ATC shutter 70 performs a closing operation (S204). After the ATC shutter 70 is closed, the tool spindle 30 starts the workpiece machining using the tool C (S103).
