Relief Plate Washer Liquid Evacuation to Protect Transport Bars
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing washer apparatus for printing plate precursors face issues of wetting and degradation of the transport system due to liquid splashing and material accumulation, leading to corrosion and malfunction.
Innovation Solution
An apparatus with a protection system that includes a liquid evacuation part extending next to the transport system, featuring an upwardly extending portion to guide and evacuate liquid away from the transport system, preventing wetting and ensuring the transport system remains dry.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a transport system is used to move printing plate precursors through washer apparatus, then the precursors can be efficiently transported and treated with liquid, but the transport system gets wetted by liquid splashing and running over, leading to corrosion and degradation
Solution Approach 1:
The patent introduces a protective barrier (intermediary structure) between the liquid treatment environment and the transport system. This barrier prevents direct contact between the liquid and the transport components, allowing the transport system to maintain its functionality without exposure to corrosive liquids while still enabling efficient precursor transport.
Solution Approach 2:
The patent extracts the harmful liquid from the transport system's environment by implementing separation mechanisms. The liquid is confined to specific treatment zones and prevented from reaching the transport components, effectively removing the corrosive element from the transport system's operational context.
2Productivity
If liquid is used to remove material from the precursor, then the washing effectiveness is improved, but the liquid becomes loaded with material that sticks to the transport system upon drying, causing malfunction
Solution Approach 1:
The patent employs barrier structures as intermediaries that prevent contaminated liquid from contacting the transport system. These barriers allow effective washing to occur in the treatment zones while blocking the pathway that would otherwise lead to material deposition on transport components.
Solution Approach 2:
The patent divides the apparatus into distinct functional zones: a liquid treatment zone where washing occurs, and a dry transport zone where the transport system operates. This segmentation ensures that the harmful effects of liquid contamination are confined to the treatment zone and do not affect the transport system.
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
The solution effectively prevents wetting of the transport system, reducing corrosion and malfunction by guiding liquid away from the transport system, thus maintaining apparatus functionality and longevity.
Implementation Method 1
The liquid evacuation part is provided with an upwardly extending portion at a side facing the transport system. In that manner, the upwardly extending portion will stop liquid flowing over the liquid evacuation part towards the transport system.
