Feeding Device Media Position Detection Air Supply
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing feeding devices in image forming apparatuses face challenges in accurately detecting the position of media due to air supply, leading to potential feed failures.
Innovation Solution
A feeding device is designed with a supply unit to float media using air, a feeder to absorb and feed the media, a separator to separate the next medium by air supply, a detector to accurately measure positions after air supply, and a modifier to adjust feeding conditions based on detected positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If air is supplied by the separator to separate the second medium from the first medium, then the separation effect is improved, but the detected position may vary and differ from the actual position
Solution Approach 1:
The detector detects the position of the first medium before air is supplied by the separator. This preliminary detection captures the position state before the separation action occurs, ensuring that the detected position reflects the actual position at the moment of feeding operation setup.
Solution Approach 2:
The modifier modifies the feeding operation conditions based on the detected position information. This feedback mechanism ensures that the feeding operation is adjusted according to the actual detected position, compensating for any variations that occur during the air supply separation process.
2Device complexity
If the position is detected before air is supplied by the separator, then the position detection is simpler, but the detected position may differ from the actual position due to air supply
Solution Approach 1:
The position detection is performed before the air supply separation action. This timing arrangement allows the detection system to capture the position in a stable state without the interference of air flow, while still providing accurate position information for the feeding operation through the modifier.
Solution Approach 2:
The modifier uses the detected position information to adjust the feeding operation conditions, creating a feedback loop that ensures accurate feeding despite the timing difference between detection and separation actions.

Function Achieved in This Case
This configuration enhances the accuracy of media position detection and reduces feed failures by ensuring precise adjustment of feeding conditions based on post-air supply positions.
Implementation Method 1
a supply unit that supplies air into space between a plurality of media loaded to float the media
Implementation Method 2
a feeder that adsorbs the media floated by the supply unit and feeds the media
Implementation Method 3
a separator that supplies air to a second medium disposed immediately below a first medium adsorbed by the feeder to separate the second medium from the first medium

AI summary
A feeding device includes: a supply unit that supplies air into space between plural media loaded to float the media; a feeder that adsorbs the media floated by the supply unit and feeds the media; a separator that supplies air to a second medium disposed immediately below a first medium adsorbed by the feeder to separate the second medium from the first medium; a detector that detects a position of at least one of the first medium and the second medium after air is supplied by the separator; and a modifier that modifies a condition related to a feeding operation of the feeder based a position detected by the detector.
