Opposite-Rotation Stacking Wheels Compact Paper Transport
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing paper-sheet processing apparatuses are too large for limited spaces in bank counters or teller desks due to the need for extended horizontal transport units and vertical stacking mechanisms, which hinder efficient use of space.
Innovation Solution
The apparatus features two or more stacking units with opposite rotation directions for their respective stacking wheels, reducing the length of the horizontal transport unit and incorporating a reject unit above the downstream stacking unit, along with a tilt portion in the transport unit to minimize size, allowing for efficient paper sheet processing and storage in a compact form.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the horizontal transport unit is extended to accommodate multiple stacking units, then the stacking capacity is improved, but the apparatus size increases
Solution Approach 1:
The patent inverts the conventional arrangement by making adjacent stacking units rotate in opposite directions rather than the same direction. This inversion allows the transport unit to serve multiple stacking units without requiring extended horizontal length, as papers can be diverted to different stacking units at different positions along the transport path.
Solution Approach 2:
The patent introduces a vertical dimension by positioning stacking units at different heights and using a tilt portion in the transport unit. This allows the apparatus to accommodate multiple stacking units without proportionally increasing the horizontal footprint, effectively utilizing three-dimensional space.
2Length of stationary object
If the stacking units are arranged in a compact configuration, then the apparatus size is reduced, but the transport path becomes more complex
Solution Approach 1:
The patent segments the transport path into multiple sections with diverters positioned at different locations. Each section can independently direct papers to different stacking units, simplifying the overall transport logic while maintaining compact dimensions.
Solution Approach 2:
The transport unit is designed with multi-functionality, serving multiple stacking units through a single compact transport path. The diverters enable the same transport unit to distribute papers to different destinations based on stacking unit capacity and paper characteristics.
3Device complexity
If adjacent stacking units rotate in the same direction, then the transport mechanism is simplified, but the apparatus length must be increased
Solution Approach 1:
The patent inverts the conventional approach by assigning opposite rotation directions to adjacent stacking units. This allows the transport mechanism to remain relatively simple while significantly reducing the horizontal length required, as papers can be diverted to upstream or downstream stacking units depending on their rotation direction.

AI summary
This paper sheet processing device is provided with a casing (10), an intake unit (20), an identification unit (60), a second transportation unit (50) for transporting sheets of paper substantially horizontally, a plurality of collection units (80, 90) for collecting the 5 sheets of paper transported by the second transportation unit (50), and vaned rollers (81, 91) provided correspondingly with respect to the collection units (80, 90). With regards to any two of the collection units (80, 90) that are adjacent to one another, the direction of rotation of the vaned roller (81) corresponding to one of the collection units (80, 90) and the direction of rotation of the vaned roller (91) corresponding to the other collection unit 10 (80, 90) are opposite each other.
