U-Shaped Conveyance Path for Image Inspection Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional conveyance systems face challenges in stabilizing the posture of conveying media during processing, leading to potential errors in image inspection and processing, particularly due to changes in conveyance direction and force application, which can result in image inaccuracies and medium deformation.
Innovation Solution
The conveyance apparatus employs a configuration with a 'U' shaped conveyance path and strategically positioned processing units, where the second processing unit is placed closer to the returning conveyance unit than the first processing unit, extending the pre-switching distance to ensure accurate image determination and minimize errors, while maintaining the medium in a stable vertical conveyance direction to prevent deformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the conveyance path is extended to increase the pre-switching distance, then image inspection accuracy is improved, but the conveyance system complexity increases
Solution Approach 1:
The conveyance system is divided into multiple conveying units (first conveying unit, returning conveying unit, second conveying unit) that operate in sequence. Each unit handles a specific segment of the conveyance path, allowing the system to achieve a long pre-switching distance through modular segmentation rather than a single complex continuous path.
Solution Approach 2:
The conveyance path utilizes vertical dimension by forming angles with the horizontal direction. The first and second conveying units are arranged at different heights, creating a three-dimensional conveyance path that extends the pre-switching distance without proportionally increasing horizontal space requirements or system complexity.
2Manufacturing precision
If processing units are positioned to stabilize medium posture, then manufacturing precision is improved, but the device complexity increases
Solution Approach 1:
The first processing unit performs processing on the first surface of the medium before the medium reaches the returning conveyance unit. This preliminary action stabilizes the medium posture during the critical pre-switching phase, ensuring accurate image determination before the conveyance direction changes.
Solution Approach 2:
The system dynamically positions processing units at specific locations along the conveyance path where they can most effectively stabilize medium posture. The second processing unit is disposed at a position closer to the returning conveyance unit, allowing adaptive processing based on the medium's position and posture requirements at different stages of conveyance.

AI summary
A conveyance apparatus includes: a first conveying unit that includes a first conveyance passage along a first direction forming an angle with respect to a horizontal direction, and conveys a medium in the first direction; a returning conveyance unit that conveys the medium towards a second direction having a component of an opposite direction to the first direction; a second conveying unit that includes a second conveyance passage along the second direction, and conveys the medium in the second direction; a first processing unit that is disposed on the first conveyance path, and performs processing on a first surface of the conveying medium; and a second processing unit that is disposed at a position closer to the returning conveyance unit than the first processing unit, and performs processing on a second surface of the conveying medium.
