Paper Feed Tray with Movable Tray for Multi-Denomination Replenishment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional banknote replenishing boxes can only store one denomination of banknotes, making it inefficient and costly to replenish multiple circulation-type banknote storage units, as each unit requires a separate box, increasing operational complexity and management workload.
Innovation Solution
A paper feed tray system that allows multiple denominations of banknotes to be stored and fed continuously from a single replenishing box, using tray pieces with regulating members to align and feed banknotes of different sizes and widths, enabling simultaneous replenishment of various types of paper sheets across multiple units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional banknote replenishing box is designed for one denomination, then the paper feed performance is maintained appropriately, but multiple boxes are required for different denominations, increasing device complexity and management workload
Solution Approach 1:
The replenishing box is designed with a movable tray that can be positioned at multiple heights, enabling a single box to accommodate and feed different denominations of banknotes with varying sizes. The tray's movable configuration allows the feed roller to contact banknotes of different dimensions, making the box universal for multiple denominations rather than requiring separate dedicated boxes for each denomination.
Solution Approach 2:
The tray is designed to be movable between different height positions, allowing dynamic adjustment of the banknote feeding surface. This dynamic structure enables the same replenishing box to adapt to different banknote sizes by changing the tray position, thereby eliminating the need for multiple static boxes designed for specific denominations.
2Reliability
If separate replenishing boxes are prepared for each denomination, then the paper feed performance is optimized for each denomination, but the workability and operational efficiency deteriorate due to repeated installation and replacement operations
Solution Approach 1:
A single replenishing box with a movable tray can handle multiple denominations, eliminating the need to repeatedly install and replace different boxes. The operator loads all required denominations into one box, and the system automatically feeds the appropriate denomination to the circulation unit, significantly improving ease of operation.
Solution Approach 2:
Multiple denomination storage functions are merged into a single replenishing box through the movable tray mechanism. Instead of using separate boxes for each denomination, the system combines them into one unified device that can switch between different denominations by adjusting the tray position, reducing operational steps.
3Reliability
If multiple replenishing boxes are used for different denominations, then each circulation unit can be replenished with the correct denomination, but the management workload and costs increase
Solution Approach 1:
The movable tray mechanism enables a single replenishing box to store and feed multiple denominations accurately. The system identifies the required denomination and positions the tray accordingly, maintaining denomination accuracy while reducing the number of boxes from multiple to one, thereby simplifying management.
4Ease of manufacture
If a fixed tray configuration is used in the replenishing box, then the structure is simple, but it cannot accommodate banknotes of different sizes
Solution Approach 1:
The tray is designed with movable capability, allowing it to change position vertically. This dynamic feature enables the simple structural design to accommodate different banknote sizes by adjusting the tray height, maintaining ease of manufacture while achieving adaptability for multiple denominations.

AI summary
Provided is a paper sheet replenishing box (paper feed device) for replenishing reserve fund in each circulation-type paper sheet storage unit, wherein paper sheets of each denomination can be replenished from one paper sheet replenishing box in which paper sheets of different denominations having different sizes are accommodated together to a circulation unit of the respective circulation-type paper sheet storage units. The paper sheet replenishing box includes a first tray piece 201 in which a plurality of pieces of first paper sheets P1 are placed in a stacked state, a second tray piece 211 arranged immediately below the first tray piece, on which a plurality of pieces of second paper sheets P2 having a different longitudinal dimension from that of the first paper sheet are placed in a stacked state, and rear-end regulating members 204 and 214 that align front end positions in a transport direction of respective paper sheet bundles to predetermined positions. After all the first paper sheets in a bundle on the first tray piece have been fed by a feed unit 160, an uppermost surface of the second paper sheets in a bundle on the second tray piece becomes a state capable of coming in contact with the feed unit.
