Relief Plate Precursor Washing With Transport-System Liquid Evacuation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Washer apparatus for printing plate precursors face issues with wetting of the transport system due to liquid splashing and corrosion, leading to malfunction, as the liquid gets loaded with precursor material and sticks upon drying.
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 corrosion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a transport system is used to move printing plate precursors through a washer apparatus, then the washing process can be performed, but the transport system gets wetted by liquid splashing and running over the transport bar
Solution Approach 1:
A protection system acts as an intermediary barrier between the liquid treatment compartment and the transport system. This protection system includes a liquid evacuation part with an upwardly extending portion that intercepts liquid before it reaches the transport bar, preventing direct contact while allowing the washing process to continue uninterrupted.
Solution Approach 2:
The harmful liquid is extracted and directed away from the transport system through the liquid evacuation part. The upwardly extending portion of the liquid evacuation part channels liquid into a reservoir, separating the liquid flow path from the transport system to prevent wetting and corrosion.
2Productivity
If brushes are used to increase washing efficiency, then material removal improves, but liquid splashing increases causing transport system wetting
Solution Approach 1:
The liquid splashing that would normally harm the transport system is redirected through the liquid evacuation part to serve a beneficial function - draining excess liquid into a reservoir. The harmful splashing action is converted into an effective liquid removal mechanism that protects the transport system while maintaining washing efficiency.
3Productivity
If liquid is used to remove material from the precursor, then washing is effective, but liquid gets loaded with precursor material and sticks to the transport system upon drying
Solution Approach 1:
The protection system serves as an intermediary that prevents material-laden liquid from contacting the transport system. By intercepting the liquid through the liquid evacuation part, the system prevents material accumulation on the transport bar, eliminating the source of future malfunctions while maintaining effective material removal from the precursor.
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 and corrosion of the transport system by guiding and evacuating liquid, ensuring efficient operation and reducing malfunctions.
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.
Implementation Method 2
the upwardly extending portion of the liquid evacuation part extends between the transport system and the upwardly extending portion of the transport bar. In that manner, liquid present on the transport bar will be stopped by the upwardly extending portion of the transport bar
