Sheet Collecting Device Movable Plate Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sheet collecting devices face issues with maintaining sheet alignment during vibration or external impacts, leading to loosening of the sheet bundle, which can result in misalignment and poor bookbinding quality.
Innovation Solution
A sheet collecting device with a horizontally positioned tray featuring a movable plate member biased towards an abutment regulating member, combined with roller means for aligning sheets, ensures that sheets remain aligned even during device vibrations by pressing the sheet edges against the regulating member, preventing loosening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If sheets are abutted against a regulating member for alignment on a horizontal tray, then sheet alignment precision is improved, but tray stability deteriorates due to vibration causing sheet loosening
Solution Approach 1:
The plate member is made movable relative to the tray, allowing it to dynamically respond to vibrations by moving with the tray while maintaining contact pressure on the sheets through the biasing member, thus preserving alignment during vibration
Solution Approach 2:
The plate member acts as an intermediary between the tray and the sheets, isolating the sheets from direct vibration effects while maintaining alignment pressure, thereby preventing sheet loosening during tray vibration
2Stability of the object's composition
If a plate member is added to prevent tray vibration effects, then sheet alignment stability is improved, but device complexity increases
Solution Approach 1:
The biasing member automatically maintains contact pressure between the plate member and sheets without external control, allowing the system to self-regulate alignment pressure during vibration without complex control mechanisms
Solution Approach 2:
The movable plate member with biasing member creates a simple dynamic mechanism that passively compensates for vibration effects, achieving stability enhancement with minimal structural complexity

AI summary
A sheet collecting device includes a tray on which sheets are placed, a sheet discharging roller for transferring sheets to the tray, an abutment regulating device for regulating a leading end and a trailing end of the sheets on the stacking tray in a conveying direction, and an aligning device for aligning the sheets relative to the abutment regulating device. The stacking tray includes a tray base supported by an apparatus frame and a plate member disposed on the tray base for placing and supporting at least some of the sheets. The plate member is supported on a top surface of the tray base so as to be movable toward an abutment regulating member. A biasing device is provided between the plate member and the tray base to bias the plate member toward the abutment regulating member.
