Robot Emergency Stop Processing Apparatus for Teaching Detachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In industrial robot systems, the detachment of teaching apparatuses often leads to emergency stop errors, hindering efficiency as it is difficult to operate the robot without causing an emergency stop, especially when the teaching apparatus is detached from the robot system.
Innovation Solution
A robot system with a control apparatus, a teaching apparatus, and an emergency stop processing apparatus that allows for separate operation of emergency stop functions, enabling the robot to continue motion even when the teaching apparatus is detached, through a communicably connected emergency stop processing apparatus that includes a second operation part for continuing robot motion and an informing part to prevent unintended detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the teaching apparatus is detached from the robot, then the robot can be operated independently, but an emergency stop error occurs and the robot motion must be restarted
Solution Approach 1:
The emergency stop processing function is segmented from the teaching apparatus into a separate emergency stop processing apparatus. This allows the teaching apparatus to be detached while the emergency stop function remains independent and stable, connected directly to the robot control system rather than through the teaching apparatus.
Solution Approach 2:
A separate emergency stop processing apparatus acts as an intermediary between the teaching apparatus and the robot control system. When the teaching apparatus is detached, this intermediary maintains the emergency stop circuit connection, preventing emergency stop errors while still allowing independent robot operation.
2Productivity
If a single teaching apparatus is used for multiple robots, then resource utilization is improved, but the user must repeatedly attach and detach the teaching apparatus reducing teaching efficiency
Solution Approach 1:
The emergency stop processing function is separated from the teaching apparatus, allowing the teaching apparatus to be quickly connected and disconnected between robots without affecting emergency stop functionality. This segmentation eliminates the time loss associated with reattaching the teaching apparatus while maintaining resource utilization benefits.
3Reliability
If the emergency stop cancel switch is provided in the control apparatus, then emergency stop errors are prevented at the control location, but it is impossible to prevent emergency stop errors at locations apart from the robot
Solution Approach 1:
The emergency stop processing apparatus provides universal emergency stop processing capability that can be accessed from multiple locations. It receives emergency stop inputs from teaching apparatuses and provides cancel functions that work across different operational contexts and locations, making the emergency stop system adaptable to various user needs.

AI summary
A robot system includes a robot, a control apparatus that controls the robot, a teaching apparatus having a first operation part that makes an emergency stop of a motion of the robot and teaching the motion of the robot, and an emergency stop processing apparatus having a second operation part that continues the motion of the robot after the first operation part is operated, wherein the second operation part is separately provided from the control apparatus.
