Banknote Storage Device Lower Guide Plate Rolling Wheel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional banknote temporary storage devices often result in folded or torn corners due to the tilting of banknote corners during processing, leading to operational issues and jamming in the conveying process.
Innovation Solution
A banknote temporary storage device featuring a pair of coiling tapes, a large coiling block, and a banknote inlet/outlet with a lower passage guide plate and vane wheels to prevent corner tilting, utilizing a rolling wheel and vane wheels to ensure smooth accommodation and discharge of banknotes, particularly those with slits, by reducing the impact angle and flapping upward corners.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of stationary object
If only one pair of thin coiling tapes is used at the central position of the large coiling block, then the rotational inertia is controlled, but the coverage of the coiling tapes for the banknotes is limited, making it difficult to form an effective confined space
Solution Approach 1:
The single pair of coiling tapes is divided into multiple pairs of coiling tapes arranged at different positions (central position and lateral positions) on the large coiling block. This segmentation allows each tape pair to handle specific regions of the banknotes, increasing overall coverage while maintaining manageable rotational inertia for each individual tape pair.
Solution Approach 2:
The coiling tapes are arranged not only at the central position but also at lateral positions along the width direction of the banknotes. This spatial distribution in multiple dimensions expands the effective confined space formed between the coiling tapes and the large coiling block, improving coverage without requiring a single oversized tape system.
2Quantity of substance
If the outer diameter of the large coiling block is increased to improve storage capacity, then more banknotes can be stored, but the effective confined space between the rotation shaft and outer clamping roller becomes insufficient, causing banknote corners to tilt upward and form folded corners
Solution Approach 1:
Multiple pairs of coiling tapes are distributed at different radial positions on the large coiling block, creating multiple confined spaces between the tapes and the block surface. This segmentation ensures that banknotes are properly confined at various locations, preventing corner tilting even when the overall block diameter is large.
Solution Approach 2:
The coiling tapes act as intermediary elements that directly contact and confine the banknotes between themselves and the large coiling block. These tapes maintain appropriate pressure and positioning throughout the winding process, ensuring banknote corners remain aligned regardless of the block's outer diameter.
3Area of stationary object
If coiling tapes are positioned to maximize coverage, then more banknotes can be handled, but the banknotes with slits may still form triangular folded corners in areas outside the deformation roller's action range
Solution Approach 1:
Multiple pairs of coiling tapes are positioned at different locations including central and lateral positions, creating overlapping zones of action. This segmentation ensures that even areas outside the deformation roller's range are covered by at least one tape pair, preventing folded corners in slit areas through distributed confinement.
Solution Approach 2:
The coiling tapes are positioned and tensioned before the banknotes are fully wound, establishing confined spaces that proactively prevent corner tilting and folded corner formation throughout the entire winding process. This preliminary positioning ensures banknotes with slits are properly constrained from the beginning.

AI summary
A temporary paper money storage device comprises: a pair of winding tapes for gripping paper money to be temporarily stored; a large winding drum for temporarily storing the paper money by receiving the winding tapes gripping the paper money to be temporarily stored; an upper winding drum assembly and a lower winding drum assembly for respectively receiving or releasing the winding tapes; and a paper money inlet/outlet comprising a pair of engaging holding rolls, the pair of engaging holding rolls comprising an upper holding roll provided on an upper rotating shaft and a lower holding roll provided on a lower rotating shaft. The large winding drum has a lower channel guide plate. An end of the lower channel guide plate is rotatably provided on the lower rotating shaft, and the other end thereof is an elastic relatively-free end formed by the pull of a spring towards the large winding drum. The tail portion of the free end has an arc shape concentric with the large winding drum, and the arc portion encloses the large winding drum at an angle of 40-50 degrees. The lower channel plate is provided with a rolling wheel thereon having a radius of 8-14 mm. Thus, paper money having a tear can be smoothly and temporarily stored and released by tightly sticking to the lower channel plate.
