Arc-Shaped Bill Dispenser Conveyance for Jam Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bill dispensers have complex and narrow conveyance passages that can lead to bill jamming, making it difficult to view and remove jammed bills, especially due to the need for sharp bends and complicated routing which increases the risk of mechanical issues during deposit and withdrawal transactions.
Innovation Solution
The introduction of an arc-shaped conveyance passage with a cylindrical drive roller and pressure rollers, along with rotatable units at the reception and temporary holding parts, allows for easy viewing and removal of jammed bills by opening the conveyance passage, reducing the risk of jamming and simplifying the structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If conveyance passages are disposed in a narrow space to miniaturize the apparatus, then the apparatus size is reduced, but the conveyance passage structure becomes complicated and bill jamming occurs more easily
Solution Approach 1:
The patent applies curvature by forming the conveyance passage in an arc shape between the discrimination part and reception part, replacing sharp angular bends with smooth curved paths. This reduces bill jamming while maintaining compact apparatus dimensions, as the curved passage allows bills to transition smoothly between different directional segments without encountering abrupt angle changes.
2Volume of moving object
If conveyance passages are disposed in a narrow space to miniaturize the apparatus, then the apparatus size is reduced, but bill jamming occurs more easily and it becomes difficult to view and remove jammed bills
Solution Approach 1:
The arc-shaped conveyance passage reduces bill jamming by eliminating sharp bends that cause bills to catch or fold. The smooth curved path allows bills to follow the contour naturally, improving conveyance reliability while maintaining compact size.
3Ease of operation
If a switching blade and switching timing sensor are provided to convey rejected bills to reject storage, then rejected bill handling is improved, but the conveyance passage becomes longer and more complicated
Solution Approach 1:
The arc-shaped conveyance passage provides a smooth transition path for bills being redirected by the switching blade. The curved geometry allows the switching mechanism to operate more effectively by providing a gradual directional change rather than an abrupt 90-degree turn, reducing bill damage and jamming at the switching point.

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 arc-shaped conveyance passage design simplifies the bill handling process, reduces jamming risks, and facilitates easy removal of stuck bills, enhancing the operational efficiency and reliability of the bill dispenser.
Implementation Method 1
a cylindrical drive roller that rotates about a rotational shaft and a plurality of pressure rollers that press an outer circumferential surface of the cylindrical drive roller

AI summary
When a bill-jam occurs in a bill dispenser, the jammed bill or the subsequent bill is easily removed.An arc-shaped conveyance passage (20) that is formed in an arc shape and that includes a cylindrical drive roller (21) rotating about a rotational shaft (21a) and plural pressure rollers (22) pressurizing an outer circumferential surface of the cylindrical drive roller, is provided in a conveyance passage connecting a discrimination part (3) to a reception part (1) in the bill dispenser. A switching blade (6) is disposed in a branch part (26) between the arc shape conveyance passage (20) and a branch conveyance passage (27) connected to a temporary holding part 4. A first unit (31) and a second unit (34) are rotated about respective rotational fulcrums (32), (35) in which the first unit (31) includes the reception part (1) and a pressure roller (22) of the arc-shaped conveyance passage (20) at the side of the reception part (1), and the second unit (34) includes the temporary holding part (4), a pressure roller (22) immediately near to the branch part (26), and the switching blade (6). The arc-shaped conveyance passage (20) is opened by rotating the first and second units (31), (34).
