Recycled Paper Storage Segmentation for Jam Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing paper sheet recycling and printing systems face issues with jamming due to paper sheet complications and inefficient operation, as they often require stopping the printing apparatus to manage recycled paper sheets for non-printing purposes, leading to reduced working efficiency.
Innovation Solution
A paper sheet recycling and printing apparatus that includes separate storage sections for recycled paper sheets manufactured under different conditions, allowing continuous operation by storing and transporting recycled paper sheets specifically for printing or non-printing uses, thereby preventing jamming and enhancing operational efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If recycled paper sheets are continuously supplied from the recycling apparatus to the paper sheet tray, then productivity is improved, but paper sheet jamming occurs due to complications when printing apparatus uses recycled sheets for non-printing purposes
Solution Approach 1:
The patent divides the recycled paper sheet storage into two separate storage sections: a first storage section for recycled paper sheets intended for printing, and a second storage section for recycled paper sheets intended for non-printing uses. This segmentation prevents mixing of different paper sheet types, eliminating jamming risks while maintaining continuous operation.
Solution Approach 2:
The patent introduces a control unit as an intermediary that manages the supply of recycled paper sheets from the recycling apparatus to the appropriate storage section. The control unit determines whether to supply sheets to the first or second storage section based on printing apparatus operation status, preventing direct supply conflicts that cause jamming.
2Reliability
If printing apparatus is stopped to manage recycled paper sheets for non-printing purposes, then paper sheet complications are resolved, but working efficiency deteriorates
Solution Approach 1:
By separating recycled paper sheets into two distinct storage sections based on their intended use, the system eliminates the need to stop the printing apparatus for sheet management. Sheets for non-printing purposes are stored separately and can be accessed without interrupting printing operations.
Solution Approach 2:
The control unit automatically manages the distribution of recycled paper sheets to the appropriate storage section based on printing apparatus operation status. This automated self-service mechanism eliminates the need for manual intervention or stopping the apparatus to manage paper sheets.
3Device complexity
If recycled paper sheets are stored in a single storage section, then device complexity is reduced, but paper sheet quality stability deteriorates due to mixing of different conditions
Solution Approach 1:
The patent implements separate storage sections for recycled paper sheets manufactured under different conditions (printing vs. non-printing uses). This segmentation maintains quality stability by preventing mixing of sheets with different physical and chemical properties, while the overall structure remains relatively simple.
Solution Approach 2:
Each storage section is designed to hold sheets with specific quality characteristics appropriate for their intended use. The first storage section maintains qualities suitable for printing, while the second storage section maintains qualities suitable for non-printing uses, ensuring local quality optimization.

AI summary
There is provided a paper sheet recycling and printing apparatus including: a paper sheet recycling section which manufactures a recycled paper sheet under a first condition and a second condition different from the first condition; a first recycled paper sheet storage section in which the recycled paper sheet manufactured under the first condition is stored; a second recycled paper sheet storage section in which the recycled paper sheet manufactured under the second condition is stored; and a printing section to which the recycled paper sheet manufactured under the first condition is supplied from the first recycled paper sheet storage section and which prints recording information on a recording target medium including the recycled paper sheet.
