Post-processor Alignment Control via Material Property Sensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing post-processors struggle to perform alignment processing with high accuracy due to variations in recording material properties such as surface state, volume, and weight influenced by environmental conditions like temperature and humidity, leading to issues like buckling or inadequate movement of recording materials.
Innovation Solution
A post-processor system that includes a medium sensor to acquire physical property values of recording materials and a controller to determine operation parameters for alignment processing, ensuring precise alignment by adjusting the alignment force based on the material's properties and environmental conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If the alignment force is increased to ensure sufficient movement of recording material, then the alignment processing can be performed, but buckling or deflection occurs in the recording material deteriorating alignment accuracy
Solution Approach 1:
The patent applies dynamics by making the alignment force adjustable and adaptive rather than fixed. The controller dynamically adjusts the alignment force based on detected physical property values of the recording material, allowing the system to optimize the balance between sufficient movement and preventing buckling for each specific material condition
Solution Approach 2:
The patent changes the parameter of alignment force based on detected physical property values of the recording material. By detecting parameters such as weight, volume, or surface state and adjusting the alignment force accordingly, the system prevents buckling while ensuring sufficient movement, thereby maintaining alignment accuracy
2Manufacturing precision
If the alignment force is decreased to prevent buckling of recording material, then the material can be moved without deformation, but the loaded recording material cannot be sufficiently moved deteriorating alignment accuracy
Solution Approach 1:
The patent implements feedback by detecting the physical property values of the recording material and using this information to adjust the alignment force. The controller receives feedback from the detection device about the material's properties and accordingly adjusts the alignment force to achieve the optimal balance between movement and deformation prevention
Solution Approach 2:
The system changes the alignment force parameter based on the detected physical properties of the recording material. By adapting the force parameter to match the actual material characteristics, the system ensures sufficient movement while preventing buckling, resolving the contradiction between force magnitude and alignment accuracy
3Adaptability or versatility
If the operation parameters of alignment processing are determined based on sheet type, then the processing can be standardized, but the variations in surface state, volume, and weight due to environmental conditions cause buckling or inadequate movement
Solution Approach 1:
The patent applies preliminary action by detecting the physical property values of the recording material before performing alignment processing. This preliminary detection allows the system to pre-adjust the alignment force and other parameters to match the specific material conditions, preventing buckling and ensuring sufficient movement from the start
Solution Approach 2:
The system changes the operation parameters of alignment processing based on the detected physical property values of the recording material. Instead of using fixed parameters for sheet type, the system adapts the force, speed, and other parameters to match the actual material state, thereby maintaining alignment accuracy despite environmental variations
