Paper Sheet Loading Device Load Adjusting Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing paper sheet loading devices face issues with smooth feeding due to excessive load from large numbers of paper sheets or mixed sizes, leading to problems like double feeding and skew, as the frictional resistance and load applied to the feed roller become uneven.
Innovation Solution
A paper sheet loading device with a load adjusting member that can protrude into the loading unit to press the front side face of the paper sheets, reducing the load on the feed roller by displacing the paper sheets inward, thereby maintaining a stable and proper load for smooth feeding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the size of the bottom plate is set matched with the maximum size of paper sheets, then large paper sheets can be supported, but erroneous feed such as skew or double feeding occurs with respect to small size paper sheets
Solution Approach 1:
The patent applies dynamics by making the bottom plate movable rather than fixed. The bottom plate can be adjusted in position to adapt to different paper sheet sizes, allowing the system to maintain both versatility and reliability. The loading device dynamically repositions the bottom plate based on the size of paper sheets being loaded, preventing feed errors while accommodating various sizes.
2Quantity of substance
If a large number of paper sheets are stacked on the bottom plate, then storage capacity is increased, but the frictional resistance becomes excessive and double feeding occurs
Solution Approach 1:
The patent applies segmentation by dividing the load-bearing function between multiple components: the bottom plate and the loading device. The loading device separately supports portions of the stacked paper sheets, segmenting the total load. This allows a large number of paper sheets to be stored while distributing the weight to prevent excessive frictional resistance and double feeding.
3Adaptability or versatility
If the loading device supports mixed sizes of paper sheets, then versatility is improved, but the load applied to the feed roller becomes uneven causing feeding problems
Solution Approach 1:
The patent applies local quality by providing differentiated support structures at different locations on the bottom plate. The loading device has loading portions that can be independently positioned to match the local characteristics of paper sheets of different sizes. This ensures that each area of the bottom plate provides appropriate support for the specific paper sheets present, maintaining load uniformity while handling mixed sizes.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution ensures smooth feeding by reducing the load on the feed roller, preventing double feeding and skew, even with large or mixed-sized paper sheets, through a simple configuration that adjusts the load dynamically.
Implementation Method 1
a frictional resistance between the surface of the lowermost banknote and the kicker roller exceeds the frictional resistance between the banknotes, thereby enabling to feed the lowermost banknote one by one

AI summary
Provided is a paper sheet loading device including a paper sheet loading unit having a bottom plate and a front wall, a feed roller that comes in contact with a bottom surface of a lowermost paper sheet of a batch of paper sheets and rotates to feed the lowermost paper sheet to outside of the paper sheet loading unit, and a load adjusting member arranged so as to protrude into the paper sheet loading unit and retreat to outside of the paper sheet loading unit. At a time of protrusion of the load adjusting member, the load adjusting member presses a front side face of the batch of paper sheets by a pressing surface to displace the front side face to an innermost part, and receives a load from the batch of paper sheets by the pressing surface, thereby reducing the load applied to the feed roller from the batch of paper sheets.
