Grinding Tool Replacement Robot for Cleaner Changeovers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Operators often get dirty when replacing processing tools in grinding devices due to the exposure to debris and particles within the device's environment.
Innovation Solution
A replacing apparatus that automates the tool replacement process by using a self-propelled robot to enter the grinding device through an exterior cover, allowing it to separate and install new tools without manual intervention, thereby minimizing exposure to contaminants.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual tool replacement is performed by operators, then the replacement process is simple and direct, but operators get dirty due to exposure to debris and particles
Solution Approach 1:
An automated replacing apparatus is introduced as an intermediary between the operator and the processing tool. The apparatus includes a replacing mechanism with a holding unit that grasps the tool, a moving mechanism that transports the tool, and operates within an exterior cover. This intermediary automates the replacement process, eliminating direct operator contact with debris and particles while maintaining efficient tool exchange.
2Object-affected harmful factors
If an automated replacing apparatus is introduced, then operator contamination is prevented, but the device complexity increases
Solution Approach 1:
The replacing apparatus integrates multiple functions into a unified structure: the replacing mechanism combines holding, moving, and installation functions; the exterior cover simultaneously protects internal components and guides the moving mechanism; the traveling table integrates support and positioning functions. This merging reduces overall system complexity despite adding automation capabilities.
Solution Approach 2:
The exterior cover serves multiple purposes: it encloses the holder and processing mechanism, guides the moving mechanism during tool replacement, and protects internal components. The replacing mechanism can both grasp and transport tools. This multi-functionality reduces the need for separate dedicated components, managing device complexity.
3Extent of automation
If the replacing apparatus enters through an entrance opening in the exterior cover, then tool replacement can be automated, but the structure becomes more complex
Solution Approach 1:
The exterior cover is segmented to include a specific entrance opening that allows the moving mechanism to access the internal space. This segmentation enables automated tool replacement while maintaining the protective enclosure. The entrance opening is positioned and sized to allow precise entry/exit of the moving mechanism without compromising the overall structural integrity or requiring extensive modifications.

AI summary
A replacing apparatus is configured to replace a processing tool in a processing apparatus. The processing apparatus includes a holder configured to hold a processing target object, a processing mechanism to which the processing tool configured to process the processing target object held by the holder is installed in a replaceable manner, and an exterior cover accommodating therein the holder and the processing mechanism. The replacing apparatus includes a replacing mechanism, a moving mechanism, a traveling table and a traveling mechanism. The replacing mechanism installs the processing tool to the processing mechanism, or separates the processing tool from the processing mechanism. The moving mechanism is configured to move the replacing mechanism from an outside of the exterior cover to an inside thereof through an entrance opening of the exterior cover. The traveling table supports the moving mechanism. The traveling mechanism is configured to allow the traveling table to travel.
