Bill Processor Circulation Path Compact Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bill processors are bulky due to their cylindrical circulation conveyance sections, leading to increased depth size and higher jamming probabilities, as well as poor maintainability, especially when trying to accommodate connection conveyance paths with tight curves.
Innovation Solution
A bill processor design featuring a circulation conveyance path with alternating linear and curved sections, allowing for a more compact layout and improved freedom in component arrangement, reducing the device's depth and enhancing maintainability by eliminating the need for restrictive cylindrical shapes and tight curves.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a cylindrical circulation conveyance section is used, then the bill can be circulated continuously, but the depth size of the bill processor increases
Solution Approach 1:
The patent replaces the conventional cylindrical circulation conveyance section with a curved conveyance path that has a gentler curvature radius. This allows the bill to circulate continuously while reducing the depth size required for the circulation path, as the gentler curve enables a more compact arrangement of the conveyance components.
2Volume of moving object
If a connection conveyance path with a tight curve is used, then the space utilization is improved, but the probability of bill jamming increases
Solution Approach 1:
The patent applies a gentler curve radius to the connection conveyance path between the circulation conveyance section and the bill storage/dispensing units. This gentler curvature reduces the likelihood of bill jamming while still achieving efficient space utilization through optimized layout of the conveyance components.
3Device complexity
If the circulation conveyance section is stored in the conveyance section, then the structure is compact, but the conveyance path has poor maintainability
Solution Approach 1:
The patent divides the conveyance system into separate functional sections: the circulation conveyance section and the connection conveyance paths. This segmentation allows the circulation section to be compactly integrated while maintaining accessible connection paths that can be easily maintained and repaired without disassembling the entire system.

AI summary
A bill processor includes a circulation conveyance path that can convey a bill to enable circulation thereof. In the circulation conveyance path, a first linear conveyance path and a second linear conveyance path are arranged to oppose each other, upper portions thereof are connected by a first curved conveyance path, and lower portions thereof are connected by a second curved conveyance path. By forming the circulation conveyance path in a rounded rectangular shape in a side view, the bill processor can be downsized in a depth direction. Each functional unit connected to the first linear conveyance path or the second linear conveyance path has a constant entry angle, at which the bill enters/exits the circulation conveyance path. In this way, the bill is conveyed stably.
