Integrated Vacuum Ejector Retaining Tool for Label Applicators
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing retaining tools for label applicator plates face inefficiencies due to large size when using fans and high energy losses when using central vacuum ejectors, which are distant from the application site.
Innovation Solution
A retaining tool with integrated pressure ducts and vacuum ejectors produced by casting or free forming of a single, solid metal or plastic piece, allowing for efficient placement of ejectors close to the vacuum source, reducing energy consumption and noise, and enabling flexible configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fans are used to provide negative pressure for label retention, then the retaining tool can hold labels in place, but the device becomes large and complex
Solution Approach 1:
The patent combines the vacuum ejector, pressure ducts, and applicator plate into a single integrated unit. The ejector is positioned directly on the applicator plate with pressure ducts connecting to multiple suction points, eliminating the need for separate fan assemblies and reducing overall device complexity while maintaining label retention capability.
Solution Approach 2:
The patent introduces pressure ducts as intermediary channels that distribute compressed air to multiple vacuum ejectors positioned at different locations on the applicator plate. This intermediary system allows efficient air distribution without requiring large centralized fans, reducing device size while maintaining effective label suction at multiple points.
2Device complexity
If a central vacuum ejector is used, then the device structure is simplified, but high energy losses occur due to the distance from the vacuum source
Solution Approach 1:
The patent divides the vacuum generation function into multiple separate ejectors positioned at different locations on the applicator plate. Each ejector serves a specific region, reducing the distance air must travel and minimizing energy losses compared to a single central ejector that would serve the entire plate.
Solution Approach 2:
The patent places vacuum ejectors at specific locations on the applicator plate where labels need to be retained. This localized positioning ensures that each ejector serves its immediate vicinity efficiently, reducing energy losses from long air travel distances while maintaining effective label retention at each suction point.
3Loss of energy
If multiple vacuum ejectors are positioned close to the application site, then energy losses are reduced and noise is suppressed, but the device complexity increases
Solution Approach 1:
The patent merges multiple vacuum ejectors, pressure ducts, and the applicator plate into a single integrated assembly. This consolidation reduces device complexity by eliminating the need for separate mounting structures and connections, while still allowing multiple ejectors to be positioned close to the application site for efficient energy use and noise suppression.
