Sheet Stacking Apparatus Tilt Correction and Holding Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sheet stacking apparatuses face the challenge of sheets tilting again after tilt correction, as existing technologies do not effectively hold the sheets in a corrected position during conveyance to the stacking part.
Innovation Solution
A sheet stacking apparatus equipped with a tilt detection sensor, correction rollers, and a sheet holder that corrects the sheet tilt and securely holds it before stacking, preventing further tilting by ensuring the sheet is aligned and stabilized during conveyance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If tilt correction is performed in the middle of conveyance path, then tilt correction can be applied to sheets, but sheets may tilt again during conveyance to stacking part
Solution Approach 1:
The sheet holder is positioned to hold the sheet immediately after tilt correction, preventing any subsequent tilting during conveyance to the stacking part. This preliminary securing action ensures the corrected position is maintained throughout the remaining conveyance path.
Solution Approach 2:
The sheet holder acts as an intermediary component between the tilt correction mechanism and the stacking part, providing continuous support and maintaining the sheet's corrected position during conveyance.
2Device complexity
If sheet is discharged after tilt correction without being held, then conveyance path is simplified, but sheet alignment cannot be maintained
Solution Approach 1:
The sheet holder secures the sheet immediately after tilt correction, maintaining alignment precision without requiring complex additional conveyance control mechanisms.

AI summary
A sheet stacking apparatus includes: a sheet stacking part on which a sheet is stacked; a tilt detection sensor arranged on an upstream side in a conveying direction of the sheet of the sheet stacking part, and which detects a tail end in the conveying direction in the conveyed sheet; a pair of correction rollers arranged on a downstream side in the conveying direction of the tilt detection sensor and arranged immediately before an upstream side in the conveying direction of the sheet stacking part, and which corrects a tilt of the sheet; and a sheet holder that holds the sheet with the tilt corrected by the pair of correction rollers, and conveys and stacks the sheet on the sheet stacking part.
