Rotary Stacking Wheel with Segmented Vanes for Paper Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing paper sheet stacking apparatuses with rotatable stacking wheels face issues with large size banknotes and checks slipping out during rotation, leading to stacking failures and require significant space for rotational trajectories, which enlarges the apparatus and complicates handling of creased sheets.
Innovation Solution
A paper sheet stacking apparatus using a rotary body with a holding member that rotates with the paper sheet, ensuring it is held throughout the process, reducing the risk of slipping and minimizing required space, and incorporating a transport assisting unit like an endless belt to guide the paper sheet edges for efficient stacking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a rotatable stacking wheel with vanes is used to stack paper sheets, then paper sheets can be automatically stacked one by one, but large size banknotes and checks may slip out from between the vanes during rotation
Solution Approach 1:
The stacking wheel is divided into multiple independent vanes that create separate holding spaces. Each vane pair forms an independent pocket to hold individual paper sheets, preventing them from slipping out during rotation. This segmentation allows the system to handle various paper sizes reliably while maintaining automatic stacking capability.
2Reliability
If a stacking wheel with vanes is used to ensure paper sheets are held during rotation, then stacking reliability improves, but the apparatus requires significant space for the rotational trajectory
Solution Approach 1:
The vanes are arranged radially on the stacking wheel, nesting the paper sheets within the wheel's structure during rotation. The paper sheets are held in pockets formed by adjacent vanes, allowing the wheel to rotate within a compact space while maintaining reliable holding of various sized documents.
3Productivity
If the stacking wheel rotates to transport paper sheets, then continuous stacking is achieved, but creased paper sheets may slip out or fail to be properly positioned
Solution Approach 1:
The inner circumferential surface of each vane is equipped with a paper sheet holding section that provides enhanced local grip. This localized feature ensures that even creased or irregular paper sheets are securely held during rotation and properly positioned when discharged, maintaining continuous stacking operation without handling failures.

AI summary
A paper sheet stacking apparatus includes: a feeding unit 26 configured to feed in paper sheets one by one from outside; a rotary body 10 including a holding member 16 for holding the paper sheet fed in by the feeding unit 26, the rotary body 10 being configured to be rotated with the paper sheet being held by the holding member 16, so as to transport the paper sheet along a rotational direction of the rotary body 10; and a stacking unit 32 on which the paper sheets transported by the rotary body 10 are stacked on one another.
