Abstract

A machine tool control device and a production system are provided which determine an operation sequence of a robot and set numerical data required in operation, by setting the selection of an operating program of a robot, and/or setting of operations of the operating program, based on an instruction by the user from the machine tool side. A numerical control device which is connected to a robot control device for controlling a robot and controls a machine tool that is used in combination with the robot, includes: a reception unit that accepts setting information for the robot; and a sending unit for sending a parameter setting a selection of an operating program of the robot, and/or setting operations of the operating program, based on the setting information accepted by the reception unit.

Claims

1. A machine tool control device which is connected to a robot control device for controlling a robot, and controls a machine tool used in combination with the robot, the machine tool control device comprising:

a reception unit for accepting, by a user inputting an instruction to an operating member in the machine tool control device, setting information including at least one of a type of hand of the robot or information relating to an arrangement of an unmachined workpiece for the robot;

a processor that determines a signal of the machine tool control device based on the setting information and sets a parameter of the robot control device based on the setting information and the signal, the parameter indicating;

an operating program, and an operation of the operating program based on the setting information accepted by the reception unit; and

a sending unit for sending the parameter to the robot control device, the parameter being for use by the robot control device in selecting an operating program in the robot control device and for use by the robot control device in setting an operation of the operating program in the robot control device.

2. The machine tool control device according to claim 1,

wherein the parameter selects the operating program from a plurality of operating programs which are executable by the robot control device.

3. The machine tool control device according to claim 1,

wherein the parameter inputs a numerical value into a variable of the operating program.

4. The machine tool control device according to claim 1,

wherein the parameter corresponds to branch processing of the operating program.

5. The machine tool control device according to claim 1,

wherein the parameter corresponds to a type of hand, arrangement of an unmachined workpiece and arrangement of a machined workpiece.

6. The machine tool control device according to claim 1, further comprising:

a display which displays a screen; and

a designation screen output unit for outputting a designation screen for designating the setting information to the display,

wherein the reception unit accepts the setting information according to an instructions input corresponding to display on the designation screen.

7. The machine tool control device according to claim 1, further comprising:

a switch for designating the setting information,

wherein the reception unit accepts a manipulation result of the switch as the setting information, and

wherein the processor generates an input signal relative to the robot control device which corresponds to the parameter, based on a manipulation result of the switch.

8. The machine tool control device according to claim 1, further comprising:

a program acquisition unit for acquiring the operating program which corresponds to the setting information accepted by the reception unit and sent to the robot control device, and then sending the operating program thus acquired to the robot control device.

9. The machine tool control device according to claim 1,

wherein the sending unit sends, to the robot control device, the parameter setting the selection of the operating program stored in the robot control device, and/or setting an operation of the operating program.

10. A production system comprising:

a robot control device that controls a robot; and

a machine tool control device that is connected to the robot control device, and controls a machine tool which is used in combination with the robot,

wherein the machine tool control device includes;

a reception unit for accepting, by a user inputting an instruction to an operating member in the machine tool control device, setting information including at least one of a type of hand of the robot or information relating to an arrangement of an unmachined workpiece for the robot;

a processor that determines a signal of the machine tool control device based on the setting information and sets a parameter of the robot control device based on the setting information and the signal, the parameter indicating;

an operating program, and an operation of the operating program based on the setting information accepted by the reception unit; and

a sending unit for sending the parameter to the robot control device, the parameter being for use by the robot control device in selecting an operating program in the robot control device and for use by the robot control device in setting an operation of the operating program in the robot control device, and

wherein the robot control device includes;

a receiving unit for receiving the parameter; and

a program setting unit for selecting the operating program of the robot based on the parameter received by the receiving unit, and setting an operation of the operating program thus selected.
