One-Side Tapes for Bill Jamming in Storage Apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medium storage and advancing apparatuses, such as those in automated teller machines, face issues with bill jamming due to torn or notched bills, which can cause curling and sticking, leading to reliability problems during the transfer process.
Innovation Solution
The apparatus employs a medium storage and advancing system with one-side reels and tapes, where the tapes are wound around the reels in a way that their width is shorter than the bill's width, allowing them to abut against both surfaces of the bill, preventing curling and ensuring proper alignment to avoid jamming.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single lower tape is used to carry bills, then the structure is simple, but torn bills may not be properly transferred and may curl or jam
Solution Approach 1:
The single lower tape is divided into multiple separate tapes (first lower tape and second lower tape) that are spaced apart. This segmentation allows each tape to independently contact different portions of the bill, providing distributed support that prevents curling and jamming of torn bills while maintaining structural simplicity
Solution Approach 2:
A guide member is introduced as an intermediary component between the drum and the lower tapes. The guide member includes a guide surface that contacts the bill and works in conjunction with the spaced-apart lower tapes to ensure proper bill alignment and transfer, preventing the bill from curling or jamming during the transfer process
2Ease of operation
If the transport guide member is disposed spaced apart from the drum, then the drum can rotate freely, but torn bills may pass through the space and cause jamming
Solution Approach 1:
The guide member acts as an intermediary that fills the space between the drum and the lower tapes. The guide surface of the guide member contacts the bill and prevents it from passing through the space between the drum and the lower tapes, thereby preventing curling and jamming while allowing the drum to rotate freely
Solution Approach 2:
The guide member is positioned specifically at the location where the bill passes through the space between the drum and lower tapes. The guide surface is oriented to contact the bill at a critical point, providing localized guidance and prevention of curling only where needed, without interfering with the overall drum rotation

AI summary
An apparatus includes one-side reels rotatably arranged, one-side tapes wound around the one-side reels, a drum arranged to rotate in one direction to wind and store a medium with the medium being laid over the one-side tapes and in an opposite direction to pull out the wound medium, and retainers opposed to the one-side tapes with respect to the medium wound by or pulled out from the drum for abutting against a surface of the medium to hold the medium, the one-side tapes having a tape width shorter than the width of the medium corresponding to the length of the medium in a direction perpendicular to a transfer direction of the medium, the one-side tapes being arranged in parallel and spaced with a spacing shorter than the width of the medium in a direction of the width of the medium to abut against another surface of the medium.
