Let

The magazine operating device 40 is provided with a touch panel 41 for input and display, and as shown in FIG. are placed in the vicinity. A signal input from the touch panel 41 is transmitted to the tool exchange control section 27 , and the tool information stored in the tool information storage section 25 is displayed on the touch panel 41 .

The display control unit 28 refers to the information stored in the tool data storage unit 25a, the tool image storage unit 25b, and the holdable tool data storage unit 25c, and displays station _S1 (attachment/removal position), station _S2 , and station S2. The information of the tool T held in the tool pot 36 in _S18 is recognized, and the image related to the recognized information is displayed on the corresponding display areas 46a, 46b and 46c from the projector 45. .

For example, the display control unit 28 first refers to the tool data storage unit 25a to obtain information on the tool pot 36 in the station _S1 and the tool T held in the tool pot 36, that is, the pot number "3". ”, tool number “00010003”, tool name “End Mill”, tool diameter “20 mm”, tool length “70 mm”, weight “9 kg”, tool material “carbide / coating”, machining cumulative time “55 hours” and limit The processing time "100 hours" is recognized. Then, the image data of the tool number "00010003" is recognized by referring to the data stored in the tool image storage unit 25b.

Next, the display control unit 28 displays an image as shown in FIG. 10 on the display area 46a based on the obtained tool information. In the example shown in FIG. 10, the recognized pot number "3", tool number "00010003", tool name "End Mill", tool diameter "20 mm", tool length "70 mm", weight "9 kg" and tool material " Cemented Carbide/Coating", remaining time until life and gauge display (a bar graph showing the limit machining time and cumulative machining time), and the image of the tool are visualized and displayed from the projector 45. It is displayed in area 46a.

Similarly, the display control unit 28 refers to the tool data storage unit 25a to recognize the information of the tool pot 36 in the station _S2 and the tool T held in the tool pot 36. FIG. In the example shown in FIG. 8, the pot number of the tool pot 36 in station _S2 is "4", but the tool T is not held in this tool pot 36. In the example shown in FIG. In this case, the display control unit 28 refers to the tool diameters of the tools T held in the tool pots 36 on both sides, and also to the information stored in the holdable tool data storage unit 25c, and displays the tool pots. The tool information that can be held at "4" is displayed in the display area 46b.

Specifically, the display control unit 28 first refers to the tool data storage unit 25a to recognize the diameters of the tools T held in the tool pots 36 of the stations _S1 and _S3 . In this example, the diameter of the tool T held in the tool pot 36 of station _S1 is "20 mm", and the diameter of the tool T held in the tool pot 36 of station _S3 is "120 mm". is also less than 200 mm.

Next, the display control unit 28 refers to the information stored in the holdable tool data storage unit 25c, and recognizes the diameter of the tool T that can be mounted on the tool pot 36 with the pot number "4". In this example, since the tool diameters of the stations _S1 and _S3 are both less than 200 mm, the maximum diameter of the tool T that can be mounted in the tool pot 36 is 200 mm. Therefore, the display control unit 28 generates an image as shown in FIG. 11 and causes the generated image to be displayed from the projector 45 on the display area 46b. Incidentally, as described above, the length of the tool T that can be held in each tool pot 36 is uniform, and the maximum length is 400 mm.

On the other hand, since the tool T is held in the tool pot 36 of the station _S18 , the display control section 28 refers to the tool data storage section 25a and displays the information of the tool T held in the tool pot 36. That is, pot number "2", tool number "00010035", tool name "Face Mill", tool diameter "100 mm", tool length "60 mm", weight "15 kg", tool material "carbide/coating", machining accumulation The time "121.2 hours" and the limit machining time "300 hours" are recognized, and the image data of the tool number "00010035" is recognized by referring to the data stored in the tool image storage unit 25b. is generated and displayed on the display area 46c from the projector 45.

Removal of the tool T and attachment of the tool T to the called pot 36 are performed.

In this manual operation, the operator first inputs from the touch panel 41 the tool pot 36 to be called to the attachment/detachment position (station S ₁ ). For example, when the operator inputs to move the tool pot 36 with the pot number "3" to the attachment/detachment position, the input control unit 42 outputs information related to the pot number "3" and a call command (operation signal). It is transmitted to the tool exchange control section 27 .

Next, when the tool change control section 27 receives this operation signal, it confirms whether the NC program execution section 22 is executing the NC program. If not, the magazine driving mechanism 39 is driven and controlled to move the tool pot 36 of the pot number "3" associated with the operation signal to the attachment/detachment position (station S ₁ ), and the NC program executing section 22 executes the NC program. If it is being executed, a signal indicating that it is being executed is sent to the magazine operator 40 . Further, after moving the tool pot 36, the tool exchange control section 27 updates the information stored in the tool information storage section 25 accordingly. Then, the display control unit 43 of the magazine operating device 40 displays, for example, on the touch panel 41 that calling is not possible.

On the other hand, the display control unit 28 displays the corresponding display areas 46a and 46a for the selected tool T with pot number "3" and the tools T with pot numbers "4" and "2" on both sides thereof as described above. In 46b and 46c, the image related to the information is displayed from the projector 45, and when the tool is not held, the image related to the tool information that can be mounted on the tool pot 36 is displayed from the projector 45 correspondingly.

In particular, information about the tool T held in the tool pot 36 at the attachment/detachment position (station S ₁ ) is displayed in the display area 46a corresponding to the attachment/detachment position (station S 1 ). Therefore, the tool T can be properly handled when the tool T is attached or detached. If the tool T is heavier than the weight normally handled, the tool T has a small diameter and low rigidity, or the tool T is made of a material with low toughness, care must be taken in handling it, and wear will progress. In the case of a tool T that is in use, it is necessary to replace the tool T. Therefore, if such information is displayed in the display area 46a, the operator can easily recognize this information and handle it. can be done properly.

In addition, since images of the tools T to be held in the tool pots 36 are displayed in the respective display areas 46a, 46b, and 46c, the displayed images can be compared with the tools T actually mounted. , the operator can easily discover incorrect attachment of the tool T, and as a result, it is possible to prevent machining using an incorrect tool.

Further, when no tool is attached to the tool pot 36 corresponding to each of the display areas 46a, 46b, 46c, information about tools that can be attached to the tool pot 36 is displayed. 36, when installing a new tool, it is possible to easily recognize whether or not the tool to be installed is appropriate.
