Dynamic Discharge Angle Adjustment for Sheet Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medium discharge devices lack mechanisms to adjust discharge speed and discharge angle, leading to poor alignment of discharged sheets, especially when handling large volumes.
Innovation Solution
A medium discharge device with a discharge roller pair that can change the discharge angle and a placement unit with a variable placement angle, both adjustable based on the discharge speed of the medium.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a fixed discharge mechanism is used, then the device structure is simple, but the alignment of discharged sheets deteriorates when handling large volumes
Solution Approach 1:
The patent applies the dynamics principle by making the discharge roller pair adjustable to change the discharge angle dynamically. The discharge roller pair can be rotated around a discharge axis to adjust the discharge angle according to discharge speed requirements, transforming a static structure into a dynamic one that adapts to different operating conditions and maintains sheet alignment.
Solution Approach 2:
The patent applies parameter changes by adjusting the discharge angle as a key parameter to control sheet alignment. By changing the discharge angle parameter in response to discharge speed variations, the system optimizes sheet placement accuracy without requiring complete structural redesign.
2Manufacturing precision
If discharge angle is fixed, then the mechanism is simple, but pressing force affects alignment when discharge speed varies
Solution Approach 1:
The discharge roller pair is designed to rotate dynamically around the discharge axis, enabling real-time adjustment of the discharge angle based on discharge speed variations. This dynamic adaptation reduces the harmful pressing force effect on sheets during high-speed discharge operations.
Solution Approach 2:
The system performs preliminary anti-action by proactively adjusting the discharge angle before pressing force can significantly degrade alignment. The adjustable mechanism anticipates the harmful effect of pressing force at varying discharge speeds and compensates by optimizing the discharge angle in advance.
3Manufacturing precision
If placement surface angle is fixed, then the structure is simple, but inertia force causes misalignment at different discharge speeds
Solution Approach 1:
The placement surface is designed with adjustable angle capability, allowing it to adapt dynamically to different discharge speeds. This enables the placement surface to counteract the effects of inertia force on discharged sheets, maintaining proper alignment despite variations in discharge velocity.
