Abstract

An information transmission system according to the present invention is constructed by connecting a transmission device which transmits information to an NC machine tool 20 via a network 2. The NC machine tool 20 comprises an operating panel 25 including an operation key 22, a keyboard 23, and a screen display section 24, and a control device 29 consisting of an input/output control section 40 which has a display control section 42. The display control section 42 receives information transmitted from the transmission device via the network 2, and display the same on the screen display section 24. Since the received information is automatically displayed on the screen display section 24 of the operating panel 25 being frequently looked at while an operator operates the NC machine tool 20, and that makes it possible to certainly give information to be given to the operator quickly and efficiently.

Claims

1. An NC machine tool comprising a machining motion mechanism, a control device which controls operation of this machining motion mechanism, and an operating panel which includes at least input means for inputting a signal to said control device, and screen display means,

wherein said control device is configured so that it can be connected to a transmission device which transmits information via telecommunication circuits, and is also configured so as to receive said information from said transmission device, and to display the received information on said screen display means.

2. The NC machine tool according to claim 1, wherein information transmitted from said transmission device to said control device is an instructing message, and said control device is configured so that a received instructing message may be displayed on said screen display means.

3. The NC machine tool according to claim 2,

wherein said input means is configured so that it can input a confirmation signal, and

wherein said control device is also configured, after displaying said instructing message on said screen display means, so as to continue the display until receiving the confirmation signal inputted from said input means, and after receiving the confirmation signal, to complete the display of said instructing message.

4. The NC machine tool according to claim 3, wherein said control device is configured, after displaying said instructing message on said screen display means, so as to make all or a part of other signals inputted from said input means invalid until receiving the confirmation signal inputted from said input means.

5. The NC machine tool according to claim 2, wherein said control device is configured so as to display said instructing message to cover all or a part of the image already displayed on said screen display means.

6. The NC machine tool according to claim 5,

wherein said input means is configured so that it can input a confirmation signal, and

wherein said control device is also configured, after displaying said instructing message on said screen display means, so as to continue the display until receiving the confirmation signal inputted from said input means, and after receiving the confirmation signal, to complete the display of said instructing message.

7. The NC machine tool according to claim 6, wherein said control device is configured, after displaying said instructing message on said screen display means, so as to make all or a part of other signals inputted from said input means invalid until receiving the confirmation signal inputted from said input means.

8. The NC machine tool according to claim 1, wherein the information transmitted from said transmission device to said control device is a machining program, and wherein said control device is configured so as to store a received machining program, also to extract a program number from this machining program, and to display an extracted program number on said screen display means.

9. The NC machine tool according to claim 8,

wherein said input means is configured so that it can input a confirmation signal, and

wherein said control device is also configured, after displaying said program number on said screen display means, so as to continue the display until receiving the confirmation signal inputted from said input means, and after receiving the confirmation signal, to complete the display of said program number.

10. The NC machine tool according to claim 9, wherein said control device is configured, after displaying said program number on said screen display means, so as to make all or a part of other signals inputted from said input means invalid until receiving the confirmation signal inputted from said input means and completing a reception of the program.

11. The NC machine tool according to claim 8, wherein said control device is configured so as to display said program number to cover all or a part of the image already displayed on said screen display means.

12. The NC machine tool according to claim 11,

wherein said input means is configured so that it can input a confirmation signal, and

wherein said control device is also configured, after displaying said program number on said screen display means, so as to continue the display until receiving the confirmation signal inputted from said input means, and after receiving the confirmation signal, to complete the display of said program number.

13. The NC machine tool according to claim 12, wherein said control device is configured, after displaying said program number on said screen display means, so as to make all or a part of other signals inputted from said input means invalid until receiving the confirmation signal inputted from said input means and completing a reception of the program.

14. The NC machine tool according to claim 8, wherein said control device is configured so that image for indicating that the machining program is under reception is displayed on said screen display means while receiving said machining program.

15. An information transmission system wherein the NC machine tool according to any one of claims 1 to 14 is connected to a transmission device which transmits information via telecommunication circuits.
