Rotating Tool Holder for Rapid Glass Cutting Head Changes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cutting heads for glass sheets require significant time and complexity for tool changes, and are costly due to the need for multiple heads or complex mechanisms to manage different glass types and thicknesses.
Innovation Solution
A cutting head with a tool changing device that allows for rapid tool switching without moving the head, featuring a rotatable tool holder with multiple cutting wheels aligned axially, enabling quick selection and positioning of the appropriate cutting wheel for the task at hand.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a tool magazine is arranged in a specific region of the working surface and the cutting head moves to change tools, then tool changing capability is provided, but time is lost due to head movement and positioning
Solution Approach 1:
The patent applies nesting by integrating multiple cutting tools directly within the cutting head assembly. The cutting head contains a tool holder with multiple cutting wheels arranged in a compact configuration, allowing one tool to be replaced by another without leaving the current working position. This nested structure eliminates the need for external tool magazines and head movement, resolving the contradiction between tool changing capability and time loss.
2Adaptability or versatility
If multiple complete cutting heads are supported by the cutting carriage, then versatility for different cut types is improved, but device complexity and costs increase significantly
Solution Approach 1:
The patent implements universality by designing a single cutting head that can perform multiple cutting functions. The tool holder within the cutting head accommodates different types of cutting wheels (e.g., for straight cutting, edge cutting, different glass thicknesses) that can be quickly interchanged. This multi-functional design eliminates the need for multiple complete cutting heads, reducing device complexity and costs while maintaining versatility.
Solution Approach 2:
The patent applies segmentation by separating the tool holder from the main cutting head body. The tool holder is designed as a distinct, replaceable component that contains only the cutting wheels, while the main cutting head retains the pneumatic, electrical, and electronic systems. This segmentation allows tools to be changed independently without affecting the complex head mechanisms, reducing overall system complexity.
3Adaptability or versatility
If a tool magazine is connected to the cutting carriage and slides along the bridge, then tool proximity to cutting head is improved, but constructive complexity increases due to engagement/disengagement mechanisms
Solution Approach 1:
The patent extracts the cutting tools from the external tool magazine concept and integrates them directly into the cutting head. By taking out the tools and placing them within the cutting head's tool holder, the patent eliminates the need for complex engagement and disengagement mechanisms between the cutting carriage and an external magazine. Tool accessibility is maintained while constructive complexity is reduced.
