Vertical Glass Drilling Spindle Scrap Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current machines for drilling and milling glass sheets face challenges in managing vibrations during processing and effectively handling scrap, which often results in damage to the finished product and increased energy expenditure due to the vertical arrangement of glass sheets.
Innovation Solution
The integration of suckers or pads as accessories with the spindle of processing heads allows for the restraint and guided removal of scrap, preventing vibrations and ensuring safe disposal of waste during drilling and milling operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If glass sheets are arranged vertically for drilling and milling operations, then processing efficiency is improved, but scrap management becomes difficult and causes vibrations damaging the finished product
Solution Approach 1:
A scraper device is introduced as an intermediary element between the processing heads and the scrap material. The scraper comprises a support structure with scraping elements that actively engage and remove scrap pieces from the glass sheet surface, preventing them from causing vibrations or damage to the finished product while maintaining vertical sheet arrangement for efficient processing
Solution Approach 2:
The processing heads are equipped with integrated scraping functionality, where the same heads that perform drilling and milling operations also incorporate scraping elements to immediately remove generated scrap. This self-service approach eliminates the need for separate scrap removal systems and continuously maintains a clean work surface during processing
2Device complexity
If scrap is allowed to fall due to gravity in vertical arrangement, then device complexity is reduced, but energy expenditure increases due to need to break up large scraps
Solution Approach 1:
The scraper acts as an intermediary that intercepts scrap pieces before they can fall to the bottom of the vertical arrangement. By actively scraping and removing scrap during processing, the system avoids the energy-intensive process of breaking up large scrap pieces while maintaining a relatively simple device structure
Solution Approach 2:
The scraping operation is performed preliminarily during the drilling and milling process itself, removing scrap pieces before they can accumulate and form large masses that would require additional energy to break down. This preliminary removal action prevents the need for subsequent scrap size reduction operations
3Manufacturing precision
If processing heads are used only for drilling and milling, then manufacturing precision is maintained, but ease of operation is reduced due to manual intervention requirements
Solution Approach 1:
The processing heads are designed with multi-functionality, serving both as drilling/milling tools and as scrap removal devices. The scraping elements are integrated into the processing heads, allowing them to perform both precision processing and scrap management functions, thereby increasing automation while maintaining precision
Solution Approach 2:
The scraping function is merged with the processing heads, combining what were previously separate operations (precision processing and scrap removal) into a single integrated device. This merging eliminates the need for manual scrap removal interventions while preserving the precision capabilities of the processing heads
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution effectively reduces damage to the finished product, enhances processing efficiency by managing scrap, and reduces energy consumption by preventing scrap from falling and being broken down into smaller pieces.
Implementation Method 1
The spindle is also used for positioning means for restraining the part of the glass sheet that will become scrap, said means comprising at least one sucker
