Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing recording-material-transporting devices face instability in preliminary separation due to varying stacking angles of recording materials, leading to inconsistent feeding performance.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the feed roller is set in a fixed position regardless of stacking amount, then the device structure is simple, but the preliminary separation effect becomes unstable when stacking angle varies
Solution Approach 1:
The feed roller's position is made dynamic rather than fixed. The support plate can rotate to adjust the feed roller's position along the transport direction, allowing the system to adapt to varying stacking angles and maintain stable preliminary separation effect regardless of stacking amount.
Solution Approach 2:
The system changes the positional parameter of the feed roller based on stacking amount. By detecting the stacking angle and adjusting the feed roller position accordingly, the system maintains optimal contact between the leading edge of recording materials and the contact part, ensuring consistent separation performance.
2Reliability
If the feed roller position is adjusted to accommodate varying stacking angles, then the preliminary separation effect is stabilized, but the device complexity increases
Solution Approach 1:
The support plate is designed to rotate about a rotation axis, enabling dynamic adjustment of the feed roller position. This mechanical degree of freedom allows the system to compensate for stacking angle variations while maintaining a relatively simple structure compared to more complex automated positioning systems.
Solution Approach 2:
The system uses the stacking angle itself as the control parameter. By detecting the stacking angle and adjusting the feed roller position accordingly, the system self-regulates to maintain optimal feeding conditions without requiring external intervention or complex control systems.
3Manufacturing precision
If a fixed feed roller position is used, then the device structure is simple, but the contact between leading edge and contact part is inconsistent
Solution Approach 1:
The system dynamically changes the feed roller's positional parameter based on the detected stacking angle. This ensures that the leading edge of the recording material consistently contacts the contact part at the optimal position, maintaining manufacturing precision and feeding consistency regardless of stacking amount.
Solution Approach 2:
The system incorporates detection of the stacking angle as feedback to adjust the feed roller position. This feedback mechanism ensures consistent contact between the leading edge and contact part by continuously monitoring and adjusting the feed roller position based on actual stacking conditions.

AI summary
A recording-material-transporting device includes a stacking part on which a recording material is stacked and that has a stacking angle varying depending on a stacking amount of recording materials stacked on the stacking part, a feed roller that feeds a recording material stacked on the stacking part, and a contact part with which a leading edge of a recording material fed by the feed roller is in contact, in which a setting position of the feed roller varies depending on the stacking angle of the stacking part based on the stacking amount of recording materials stacked on the stacking part.
