Rotatable Glue Scraper Adjustment for Faster Orientation Changes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing glue distribution devices in labelling systems require repeated adjustment of scraper positions when switching between different orientations, leading to increased operational costs and downtime.
Innovation Solution
A glue distribution device with an adjustment system that allows maintaining the pre-set position of scrapers during orientation changes, using a rotatable adjustment mechanism to lock the scraping groups in place, thereby simplifying the replacement process and reducing the need for re-adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the scraper position is adjusted for each orientation change, then the glue level regulation is precise, but the operational time and cost increase
Solution Approach 1:
The adjustment system is configured to maintain the previously set scraper position automatically when the scraping group is reinstalled after orientation change. This preliminary action of preserving the adjustment eliminates the need for repeated adjustments, resolving the contradiction between precision and time loss.
Solution Approach 2:
The adjustment system serves itself by automatically retaining the set position without requiring operator intervention. The system self-maintains the precise scraper position through its mechanical memory function, reducing both time loss and operational complexity.
2Stability of the object's composition
If the adjustment system is fixed, then the scraper position can be maintained, but the scraping group replacement becomes complex
Solution Approach 1:
The adjustment system transitions between two states: locked during operation to maintain position stability, and unlocked during replacement to simplify operations. This dynamic behavior resolves the contradiction between stability and complexity by adapting the system's rigidity to the operational phase.
Solution Approach 2:
The adjustment system is separated into the stationary frame portion and the movable scraping group portion. This segmentation allows the adjustment settings to be preserved in the frame while the scraping group can be independently replaced, reducing the complexity of the overall replacement process.
3Productivity
If the scraper position is re-adjusted after replacement, then the glue distribution is optimized, but the global operational cost increases
Solution Approach 1:
The system performs the optimization action in advance by maintaining the scraper position automatically. This preliminary preservation of the optimized position eliminates the need for repeated adjustment operations, reducing operational costs while maintaining productivity.
Solution Approach 2:
The adjustment system provides feedback by remembering the previously optimized position. This feedback mechanism ensures that the same optimal settings are reused, maintaining productivity while eliminating the energy and cost associated with repeated adjustments.
