Automated Tool Receptacle for Rapid Small-Series Shaping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shaping machine tools, particularly automatic stamping machines, face challenges with time-consuming and costly tool changes due to limited tool selection and non-standardized tool interfaces, making it difficult to produce small series of articles economically without extensive warehousing.
Innovation Solution
A machine tool system with a tool receptacle, feed, and controller that automates tool selection and fastening using machine-readable codes and sensors, allowing for automated tool changes without manual intervention, and includes a transport device for circulating tools and a control unit to manage production parameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual tool change is used, then tool selection flexibility is maintained, but tool change time increases and productivity decreases
Solution Approach 1:
The system prepares multiple tools in advance within the tool receptacle, with each tool pre-positioned and identified by machine-readable codes. The controller pre-plans tool changes based on production requirements, eliminating the need for manual tool selection and change during operation.
Solution Approach 2:
The machine tool performs tool changes automatically using its own control system, sensor detection, and automated tool feed mechanisms. The system self-manages tool selection, retrieval, and installation without human intervention, significantly reducing tool change time and increasing productivity.
2Productivity
If automated tool stocking system is implemented, then tool change speed increases, but device complexity increases
Solution Approach 1:
The tool receptacle serves multiple functions: it stores multiple different tools, provides automated tool feeding, contains machine-readable code readers for tool identification, and integrates with the controller for automated tool change management. This multi-functionality reduces the need for separate dedicated systems.
Solution Approach 2:
Machine-readable codes serve as intermediaries between the physical tools and the digital control system. These codes enable automatic tool identification and tracking without complex mechanical interfaces or manual input, simplifying the connection between the physical tool stock and the automated control system.
3Adaptability or versatility
If frequent tool changes are performed for small series production, then production flexibility is maintained, but production cost increases
Solution Approach 1:
The system pre-loads the tool receptacle with all necessary tools for a production batch before production begins. The controller pre-plans the tool change sequence based on the production program, allowing frequent tool changes without interrupting production flow or requiring manual intervention, thereby maintaining flexibility while reducing costs.
