Abstract

A robot control system provided in a machining system including a robot and a machine tool. The robot control system includes a robot controller controlling the robot, a portable teach pendant connected to the robot controller, and a communication network adapted to connect the robot controller to a machine tool controller controlling the machine tool. The teach pendant includes a display section configured to display information relating to the robot and the machine tool. The robot controller includes a processing section configured to obtain information relating to the machine tool from the machine tool controller through the communication network, make the display section of the teach pendant display a machine tool-related screen in accordance with a given screen program, and make the machine tool-related screen of the display section of the teach pendant display the information, as obtained, relating to the machine tool.

Claims

1. A robot control system provided in a machining system comprising a robot and a machine tool, the robot control system comprising:

a robot controller controlling the robot;

a portable teach pendant connected to said robot controller; and

a communication network adapted to connect said robot controller to a machine tool controller controlling the machine tool;

wherein said teach pendant comprises a display section configured to display information relating to the robot and the machine tool; and

wherein said robot controller comprises a processing section configured to obtain information relating to the machine tool from the machine tool controller through said communication network, make said display section of said teach pendant display a machine tool-related screen in accordance with a given screen program, and make said machine tool-related screen of said display section of said teach pendant display said information, as obtained, relating to the machine tool.

2. The robot control system of claim 1, wherein said processing section is configured to process an input operation onto said machine tool-related screen of said display section of said teach pendant, and transmit a content of said input operation to the machine tool controller through said communication network.

3. The robot control system of claim 1, wherein said robot controller is connected through said communication network to a plurality of machine tool controllers respectively controlling different machine tools;

and wherein said processing section is configured to detect the plurality of machine tool controllers connected through said communication network to said robot controller, make said machine tool-related screen of said display section of said teach pendant display a selecting section provided for a selection of a desired machine tool controller from among the plurality of machine tool controllers, and make said machine tool-related screen display said information obtained from the desired machine tool controller selected by said selecting section.

4. The robot control system of claim 3, wherein said processing section is configured to obtain given parameter information of the machine tool controlled by the desired machine tool controller selected by said selecting section, from the desired machine tool controller through said communication network, and prepare said machine tool-related screen based on said given parameter information as obtained.

5. The robot control system of claim 1, wherein said processing section is configured to obtain a position of a control axis of the machine tool from the machine tool controller through said communication network, and make said machine tool-related screen of said display section of said teach pendant display said position of the control axis as obtained.

6. The robot control system of claim 5, wherein said processing section is configured to obtain a name of the control axis of the machine tool from the machine tool controller, and make said machine tool-related screen display said name of the control axis as obtained, as being related to said position of the control axis.

7. The robot control system of claim 1, wherein said processing section is configured to obtain a feed speed and a spindle rotation number of the machine tool from the machine tool controller through said communication network, and make said machine tool-related screen of said display section of said teach pendant display said feed speed and said spindle rotation number as obtained.

8. The robot control system of claim 1, wherein said processing section is configured to obtain an operational mode of the machine tool from the machine tool controller through said communication network, and make said machine tool-related screen of said display section of said teach pendant display said operational mode as obtained.

9. The robot control system of claim 1, wherein said processing section is configured to obtain a machining program executed in the machine tool controller, from the machine tool controller through said communication network, and make said machine tool-related screen of said display section of said teach pendant display said machining program as obtained.

10. The robot control system of claim 1, wherein, when the machine tool generates an alarm, said processing section is configured to obtain information of the alarm from the machine tool controller through said communication network, and make said machine tool-related screen of said display section of said teach pendant display said information of the alarm as obtained.

11. The robot control system of claim 2, wherein said processing section is configured to transmit an operation command to the machine tool controller, based on said input operation onto said machine tool-related screen of said display section of said teach pendant.

12. The robot control system of claim 2, wherein said processing section is configured to transmit commands for setting and changing a parameter relating to the machine tool, based on said input operation onto said machine tool-related screen of said display section of said teach pendant.

13. The robot control system of claim 12, wherein said parameter relating to the machine tool is at least one of a feed speed, a spindle rotation number, an operational mode, a position of an executed line in an executed machining program, and a tool correction value, set in the machine tool.
