Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medium conveying apparatuses face challenges in reducing conveyance time while minimizing the occurrence of conveyance abnormalities such as jam, slip, multi-feed, and skew, especially when increasing conveyance speed.
Innovation Solution
The apparatus includes a determination module to assess whether conveyance abnormalities have occurred after a predetermined number of media are conveyed, and a control module that adjusts the conveyance speed or interval accordingly to prevent abnormalities and optimize conveyance efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conveyance speed is increased to reduce conveyance time, then productivity is improved, but conveyance abnormalities such as jam, slip, multi-feed, and skew occur more frequently
Solution Approach 1:
The patent implements dynamic adjustment of conveyance speed based on real-time detection of medium characteristics. The control unit modifies the conveyance speed during operation according to detected medium properties, allowing the system to optimize between speed and reliability for each specific medium condition rather than using a fixed speed setting
Solution Approach 2:
The patent changes the conveyance speed parameter dynamically based on detected medium characteristics. When medium properties indicate higher reliability at lower speeds, the system adjusts the speed parameter accordingly, and vice versa, enabling continuous optimization of the balance between productivity and reliability
2Loss of time
If conveyance speed is increased to reduce time required for conveying medium, then loss of time is reduced, but conveyance abnormalities occur more frequently
Solution Approach 1:
The system dynamically adjusts conveyance speed based on real-time medium detection, allowing faster conveyance when medium conditions permit and slower conveyance when abnormalities are detected, thereby optimizing the balance between time loss and reliability
Solution Approach 2:
The detection unit continuously monitors medium characteristics during conveyance and provides feedback to the control unit, which then adjusts the conveyance speed in real-time to prevent abnormalities while maintaining efficient conveyance time

AI summary
Provided are a medium conveying apparatus, a control method, and a control program is to enable further reduction in the time required for conveying the medium while suppressing the occurrence of the conveyance abnormality of the medium. A medium conveying apparatus includes a conveying mechanism to convey a medium, a determination module to determine whether a conveyance abnormality of the medium has occurred, and a control module to control the conveying mechanism so as to increase a conveyance speed of the medium to be conveyed thereafter, or reduce a conveyance interval of the medium to be conveyed thereafter if the conveyance abnormality of the medium has not occurred when a predetermined number of medium is conveyed.
