Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional paper sheet conveyance devices using airstreams face challenges in maintaining a straight conveyance path, especially in gaming machine units with narrow spaces, leading to paper sheet jamming and instability due to uneven airflow and improper fixation of capturing devices.
Innovation Solution
The implementation of a paper sheet conveyance device with a separation/collection device that includes a rib on the inner wall of the conveyance path to prevent paper sheet clinging, a rotatable conveyance belt for smooth paper sheet movement, and adjustable airflow strength based on the conveyance subsidiary body's position, ensuring stable and jam-free conveyance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a conventional airstream conveyance device is used in narrow gaming machine spaces, then the device structure is simplified, but the conveyance path becomes curved causing paper sheet jamming and instability
Solution Approach 1:
The conveyance path is divided into multiple straight sections connected by turning portions with large turning radii. The path includes a first conveyance path, a first turning portion, a second conveyance path, and a second turning portion, creating segmented straight sections that reduce paper sheet jamming while adapting to narrow gaming machine spaces
Solution Approach 2:
The turning portions are designed with large turning radii to smoothly guide paper sheets from one straight conveyance path to another. This curved transition minimizes abrupt directional changes that cause jamming, while the overall path remains adapted to the narrow gaming machine environment
2Reliability
If the conveyance path is made straight to prevent paper sheet jamming, then paper sheet conveyance stability is improved, but the device cannot adapt to narrow gaming machine spaces
Solution Approach 1:
The conveyance path is segmented into multiple straight sections (first conveyance path, second conveyance path) connected by turning portions. This segmentation maintains straight conveyance sections for stability while using turning portions to adapt to the narrow gaming machine space layout
Solution Approach 2:
The conveyance device utilizes three-dimensional space by positioning turning portions at different heights and using vertical clearance. The path can extend in multiple spatial dimensions, allowing straight conveyance sections to be maintained while adapting to narrow horizontal spaces through vertical utilization
3Ease of manufacture
If paper sheet capturing devices are attached to the rear surface of game ball lending devices, then the conveyance path can be formed, but the path becomes curved and paper sheet jamming occurs
Solution Approach 1:
The conveyance path is segmented into straight sections and turning portions, allowing the path to be formed by attaching capturing devices to rear surfaces while maintaining straight conveyance sections for stability and reducing jamming
Solution Approach 2:
Turning portions with large turning radii are introduced to smoothly connect straight conveyance path sections. These curved transitions prevent paper sheet jamming that would otherwise occur at sharp angles, while still allowing the path to be formed by attaching devices to rear surfaces of game ball lending devices
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 enables smooth collection of paper sheets without crushing, maintains a straight conveyance path, and adjusts airflow to prevent jamming, effectively conveying inelastic, curled, or rolled paper sheets.
Implementation Method 1
a conveyance device which generates airstream in a cylindrical conveyance duct by using an air blower and conveys the paper sheet by using the airstream
Implementation Method 2
a sucking port for sucking the air in the path part from the outside via the rear of the conveyance belt 98B, wherein the paper sheet 6 passing through the passing port 84 of the separation unit 80 clings to the conveyance belt 98B by sucking the air in the path part

AI summary
A separation/collection device is provided in a paper sheet conveyance device for generating an airstream in a conveyance duct and for conveying a paper sheet inserted into the conveyance duct by being pushed from behind by a conveyance subsidiary body moving in the conveyance duct by receiving the airstream. The separation/collection device separates and collects the conveyance subsidiary body and the paper sheet at an ending portion of a conveyance path. The separation/collection device includes a separation unit that passes the paper sheet pushed and conveyed by the conveyance subsidiary body, in a downstream direction, and that stops the conveyance subsidiary body by contacting the conveyance subsidiary body with the separation unit, a tubular path part that receives the paper sheet output from the separation unit, and a rib provided on an inner wall of the path part.
