Paper Sheet Pressing Member for Stable Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing paper sheet accommodating units face issues with erroneous transfer and instability during the handling of paper sheets due to insufficient pressing time and inadequate support, leading to displacement or drop, especially when handling sheets of varying widths.
Innovation Solution
A paper sheet accommodating unit is designed with a pressing member arranged between rotating bodies that support the paper sheet's edges, ensuring a longer pressing time and sufficient support through recesses with increased depth and width, allowing for stable transfer onto a loading platform while minimizing contact time with rotating bodies to prevent displacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the distance between push-in rotating bodies is set wide to match the width of a banknote with the maximum size, then it is possible to accommodate banknotes of various widths, but a banknote with a narrower width can be easily displaced in the width direction or drop from the supporting concave portions
Solution Approach 1:
The patent applies local quality by providing different structural characteristics at different locations: the push-in rotating bodies have supporting concave portions with specific depth and width dimensions that create localized support zones. These concave portions are positioned to provide adequate support for narrow banknotes while maintaining the overall wide distance between rotating bodies to accommodate maximum size banknotes. This localized structural optimization resolves the contradiction between versatility and reliability.
2Productivity
If the push-in member continues to press the banknote for a short time after protruding, then the pressing operation is quick and efficient, but the time during which the push-in member stays at the push-in position is insufficient, causing pressing to rely only on the rotating bodies which can easily displace the banknote
Solution Approach 1:
The patent applies preliminary action by ensuring the push-in member maintains contact with the banknote for an extended duration during the pressing operation. The push-in member protrudes and presses the banknote against the loading platform, maintaining this position long enough to ensure stable transfer before retracting. This preliminary sustained pressing action prevents subsequent displacement by the rotating bodies, resolving the contradiction between operational speed and positioning stability.
3Duration of action of moving object
If the push-in rotating bodies continue to rotate and press the banknote for a long time after the push-in member retreats, then the banknote is continuously supported, but the rotating bodies are in contact with the banknote while rotating, causing easy displacement in the width direction
Solution Approach 1:
The patent applies the taking out principle by extracting the primary pressing function from the rotating push-in bodies and assigning it to the dedicated push-in member. The push-in rotating bodies are removed from the continuous pressing task and instead serve only to support and guide the banknote during transfer. This separation of functions allows the push-in member to provide sustained pressing without the disruptive rotation, while the rotating bodies provide stable support without causing displacement.
4Volume of moving object
If the recesses in the rotating bodies have small opening width, then the rotating bodies can be compact, but there is insufficient room for setting both ends of the banknote in the recesses
Solution Approach 1:
The patent applies dimensionality change by optimizing the recess geometry in multiple dimensions: the recesses have sufficient opening width in the horizontal dimension to accommodate banknote edges, adequate depth in the vertical dimension to provide secure support, and appropriate circumferential positioning to enable proper banknote placement. This multi-dimensional optimization allows compact rotating bodies while maintaining ease of operation for setting banknote edges.

AI summary
To prevent erroneous transfer onto a paper sheet loading platform and improve the operation stability over the entire length of a long-edge direction of a pressing member by ensuring a long time during which the pressing member continues to push in a paper sheet alone. To include two rotating bodies 120 and 130 that have recesses 120a and 130a and are rotatable in opposite directions to each other in synchronization with each other, a pressing member 140 that is movable and presses an intermediate portion of a back of a paper sheet forward, a drive mechanism 180, and a paper sheet loading platform 200. The drive mechanism rotates each rotating body by an angle from 195 degrees to 270 degrees in a time period after the pressing member starts to bring a center of the paper sheet into contact with the paper sheet loading platform from an initial state until the pressing member leaves the center of the paper sheet.
