Fold Position Adjustment Using Image Pattern Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing devices face challenges in accurately adjusting the fold position of recording paper due to variations in paper characteristics, leading to inconsistent fold positions.
Innovation Solution
An image processing device that includes a fold unit, an image reader, and a position identifying unit, which reads an adjustment pattern on a sheet, identifies the fold line position, and adjusts the fold position based on the difference between the identified position and a reference fold position, using a controller to set the correct fold position for precise folding.

1Productivity
If a predetermined reference fold position is used for folding recording paper, then the folding process is simple and fast, but the fold position accuracy deteriorates due to variations in paper characteristics
Solution Approach 1:
The system performs preliminary actions by printing adjustment patterns on the recording paper before folding, then reading these patterns with an image reader to detect the actual paper position. This preliminary detection allows the system to calculate and apply position corrections before the actual folding operation, thereby maintaining both high speed and high accuracy.
Solution Approach 2:
The system implements feedback by detecting the actual position of the recording paper using an image reader that reads adjustment patterns, comparing this detected position with the reference fold position, and automatically adjusting the fold position based on the detected deviation. This closed-loop feedback mechanism ensures accurate folding despite variations in paper characteristics while maintaining efficient operation.
2Manufacturing precision
If manual adjustment of fold position is performed to account for paper variations, then fold position accuracy is improved, but the operation complexity and time increase
Solution Approach 1:
The system enables self-service by automatically detecting paper position variations through adjustment patterns, calculating the required corrections, and adjusting the fold position without requiring manual measurement or adjustment by operators. The image processing device performs all adjustment operations autonomously, significantly reducing operational complexity while maintaining high precision.
Solution Approach 2:
The system replaces manual mechanical adjustment operations with an automated image processing and control system. Instead of physically measuring and adjusting fold positions manually, the system uses an image reader to detect paper position, processes the image data to calculate deviations, and automatically controls the folding mechanism, thereby reducing operational complexity while improving accuracy.
3Manufacturing precision
If manual measurement and adjustment of fold position is performed, then fold position accuracy is improved, but the adjustment time increases
Solution Approach 1:
The system performs preliminary detection of paper position using pre-printed adjustment patterns before the folding operation. By reading these patterns with an image reader and calculating position deviations in advance, the system prepares the correct fold position settings beforehand, enabling rapid adjustment without time-consuming manual measurements during the actual folding process.
Solution Approach 2:
The system replaces time-consuming manual measurement operations with rapid automated image reading and processing. The image reader quickly captures the adjustment patterns, and the control unit automatically calculates position deviations and adjusts fold settings, significantly reducing adjustment time compared to manual measurement methods while maintaining high accuracy.

AI summary
An image processing device includes: a fold unit that folds an adjustment sheet, in which an adjustment pattern is formed, over the adjustment pattern based on a predetermined reference fold position; an image reader that reads an image of the adjustment pattern of the adjustment sheet with the adjustment sheet folded by the fold unit unfolded; a position identifying unit that, based on a fold line which appears in the image of the adjustment pattern read by the image reader, identifies a position of the fold line; and a fold position adjusting unit that adjusts a fold position of the fold unit based on a difference between the position of the fold line identified by the position identifying unit and the reference fold position.
