Machine Tool Loading Device With Mobile Blocking Means
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing machine tools and work centers face challenges in efficiently loading and unloading long, symmetrical pieces like chair parts, requiring multiple complex configurations and adjustments to accommodate different reference surfaces for various pieces.
Innovation Solution
A loading device with a magazine, mobile support, blocking means, and unloading mechanisms that utilize numeric control axes for precise positioning and handling of workpieces, allowing for automatic or semi-automatic loading and unloading of long pieces, with adjustable blocking elements and reference surfaces to accommodate different shapes and sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple complex configurations and adjustments are used to accommodate different reference surfaces for various pieces, then the machine tool can handle different shapes and sizes, but the device complexity increases
Solution Approach 1:
The blocking means is designed to perform multiple functions: it blocks workpieces during machining, transfers workpieces from the magazine to the work area, and handles both loading and unloading operations. This multi-functionality eliminates the need for separate specialized devices for each operation, reducing overall device complexity while maintaining versatility across different workpiece types
Solution Approach 2:
The blocking means is made mobile along a numeric control translation axis, allowing dynamic repositioning to accommodate different workpiece configurations and reference surfaces. This dynamic capability enables the same blocking means to adapt to various workpiece geometries without requiring multiple fixed configurations or manual adjustments
2Device complexity
If a limited number of elements are used for loading and unloading, then the device complexity is reduced, but the ease of operation may worsen due to multi-functional requirements
Solution Approach 1:
The blocking means automatically performs both loading and unloading functions through its mobile design and integration with the magazine system. The system serves itself by using the same blocking means for both workpiece introduction and removal, eliminating the need for separate loading and unloading mechanisms and simplifying operation through automation
3Reliability
If the blocking means is raised in relation to the saddle, then the reliability is improved by avoiding tool collision, but the position adjustment complexity increases
Solution Approach 1:
The blocking means is integrated with the mobile saddle and moves dynamically with it along the numeric control translation axis. This dynamic integration ensures that the blocking means maintains its raised position relative to the saddle while automatically adjusting to different work areas, avoiding tool collision without requiring separate position adjustment mechanisms
