Decoloring Apparatus Image Consistency Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current decoloring apparatuses incorrectly identify papers with only non-decolorable forms as defective, leading to unnecessary rejection of reusable papers, as they fail to differentiate between decolored images and remaining non-decolorable forms during the decoloring process.
Innovation Solution
A decoloring apparatus equipped with a scanner, memory, and control section that determines whether the scanned image matches a predetermined form, and conveys papers with matching images to specific discharging positions, allowing for the separation of papers with only non-decolorable forms from those with residual decolorable images.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the scanner scans all papers after decoloring processing to detect residual images, then the reliability of defect detection is improved, but the paper on which only the predetermined form remains is incorrectly determined as defective
Solution Approach 1:
The patent segments the image recognition task by comparing the scanned image against a predetermined form template. The control section determines whether the scanned image matches the predetermined form, separating papers with only forms from papers with residual images. This segmentation resolves the contradiction by enabling reliable defect detection while correctly identifying reusable papers.
2Device complexity
If the control section determines all papers with images as defective, then the simplicity of the judgment process is improved, but the distinction between decolored images and non-decolorable forms cannot be made
Solution Approach 1:
The patent applies preliminary action by pre-storing the predetermined form template in the control section before the scanning process. This allows the system to directly compare scanned images against the known form pattern, enabling precise differentiation between forms and residual images without complex real-time analysis, thus resolving the contradiction between simplicity and precision.
3Device complexity
If papers with only predetermined forms are discharged to the same position as defective papers, then the simplicity of the discharge mechanism is improved, but the productivity of paper recycling is reduced due to mixing reusable and non-reusable papers
Solution Approach 1:
The patent segments the paper discharge into multiple positions: a first discharge position for papers containing residual images (defective) and a second discharge position for papers containing only the predetermined form (reusable). This segmentation enables the discharge mechanism to maintain simplicity while improving recycling productivity by separating reusable from non-reusable papers.

AI summary
A decoloring apparatus (1) comprises a decoloring unit (12) configured to carry out a decoloring processing which decolors the color of an image formed on a paper (S) with a decolorable color material; a scanner (13) configured to scan the papers (S) to which the decoloring processing is carried out; a memory (15) configured to store data of a predetermined image indicating a predetermined form formed on the paper (S); a conveyance section (17) configured to convey the paper (S) scanned by the scanner (13) to a plurality of paper discharging positions (21, 22, 23); and a control section (14) configured to determine whether or not the scan image generated by the scanner (13) is consistent with the predetermined image, and to drive the conveyance section (17) to respectively convey the papers (S) on each of which the scan image is consistent with the predetermined image and the papers (S) on each of which the scan image is not consistent with the predetermined image to different positions (21, 22, 23).
