Solution Overview

Problem

In machining systems, inexperienced users face difficulties in setting up robot operations due to the need for manual input on robot-specific teaching control panels, which are separate from machine tool control devices, limiting the ability to integrate and coordinate machine tool and robot operations effectively.

Innovation Solution

A machine tool control device that connects to a robot control device, allowing for the acceptance and transmission of setting information, including parameter selection and input for the robot's operating program, enabling users to set up robot operations from the machine tool side through a user-friendly interface, such as a designation screen or switch inputs, and send these settings to the robot control device for execution.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If robot setting operations are performed on the robot control device side, then the robot can be controlled independently, but inexperienced machine tool users cannot perform setting operations by themselves

Engineering Contradiction:
Improveease of robot setting operationVSAvoidcomplexity of control system
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent merges the robot control device and machine tool control device into an integrated control system. The robot control device includes a machine tool control unit that allows machine tool users to perform robot setting operations through a unified interface, eliminating the need to separately access the robot teaching control panel. This integration enables inexperienced users to configure robot operations while maintaining system functionality.

Inventive Principle:
Principle #5Merging (Combining)

2Adaptability or versatility

If separate control devices are used for machine tool and robot, then each device can be optimized independently, but the setting operation on robot side cannot be performed by machine tool user

Engineering Contradiction:
Improveadaptability of control systemVSAvoidease of setting operation
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The robot control device is designed with multi-functionality, incorporating both robot control capabilities and machine tool control functions. The machine tool control unit within the robot control device provides a universal interface that allows machine tool users to perform robot setting operations, while the system maintains separate optimization capabilities for both robot and machine tool operations.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Ease of operation

If machine tool control device accepts robot setting information, then user can set robot operations from machine tool side, but communication interface must be established between control devices

Engineering Contradiction:
Improveease of robot configurationVSAvoidcomplexity of communication interface
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The control devices are merged into an integrated system where the robot control device includes a machine tool control unit. This integration eliminates the need for complex external communication interfaces between separate devices, as the machine tool control unit directly receives and processes robot setting information from the machine tool side through unified input interfaces.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

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.
