Tailing End Supporting Member for Sheet Bundle Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sheet storing apparatuses face issues with sheet bundle collapse due to drop impact and positional deviation when storing sheets with varying thickness and curl, leading to increased complexity and cost, particularly when the height difference between the discharging port and the sheet placement face is large.
Innovation Solution
A tailing end supporting member is positioned at a middle height between the discharging port and the sheet placement face, movable to and from a side above the tray, with a first height difference larger than the maximum bundle thickness and a second height difference smaller than the first, allowing the member to swing between two angles to softly land the sheet bundle and prevent disturbance of stacked sheets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a large height difference is set between the discharging port and the sheet placement face, then the number of sheet bundles that can be stored is increased and control is simplified, but sheet bundles collapse due to drop impact
Solution Approach 1:
A sheet bundle receiving member is provided at the sheet placement face to receive and cushion the sheet bundle before it fully settles. This receiving member acts as a buffer that absorbs the impact energy during the dropping process, preventing the sheet bundle from collapsing while still allowing the tray to be positioned at a higher level for increased storage capacity
2Device complexity
If a large height difference is set between the discharging port and the sheet placement face, then control complexity is reduced, but positional deviation of sheet bundles occurs
Solution Approach 1:
The sheet bundle receiving member serves as an intermediary between the discharging port and the sheet placement face. It temporarily holds the sheet bundle during its descent, allowing for controlled positioning even with a large height difference, thereby maintaining positioning accuracy without requiring complex control mechanisms
3Reliability
If the height difference is reduced to prevent sheet bundle collapse, then sheet bundle stability is improved, but the number of sheet bundles that can be stored decreases
Solution Approach 1:
The sheet bundle receiving member provides cushioning support at the moment of impact, enabling the system to maintain a large height difference for increased storage capacity while still protecting sheet bundles from collapse. This eliminates the need to reduce the height difference
4Reliability
If a supporting member is arranged between the discharging port and sheet placement face, then sheet bundle impact is reduced, but apparatus complexity and cost increase
Solution Approach 1:
The sheet bundle receiving member is designed to be automatically engaged by the descending sheet bundle without requiring active control mechanisms. The sheet bundle's own weight and motion activate the receiving member, which then passively provides the necessary cushioning support, reducing overall system complexity while maintaining high reliability

AI summary
In a sheet storing apparatus of the present invention, a tailing end supporting member which temporarily supports a tailing end of a dropping sheet bundle is arranged between a discharging port of a processing tray to discharge the sheet bundle and the upmost sheet on a stack tray as being movable between an operating position above a sheet placement face and a waiting position outside the stack tray.
