Conveying Direction Switching Apparatus for Torn Bills
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional automatic cash transaction apparatuses face issues with conveying direction switching, as existing guide members fail to securely guide bills with superficial tears, leading to potential folding, breaking, or jamming at branching points.
Innovation Solution
A conveying direction switching apparatus featuring a primary guide member and an auxiliary guide member, with a rotatable shaft and blades, ensures secure guidance of bills without interrupting the conveying channel, using guide surfaces to direct bills effectively in both directions, preventing deviation and jamming.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a guide member is positioned beside the conveying channel to guide bills in the branch direction, then the direction switching function is achieved, but bills with superficial tears cannot be properly held and may lean out, fold, or break
Solution Approach 1:
The guide member is divided into two distinct segments: a first guide member positioned beside the conveying channel that guides bills in the forward direction, and a second guide member positioned on the side of the branching path that guides bills in the branch direction. This segmentation allows each guide member to perform its specific function without interfering with the other, ensuring reliable guidance for bills with superficial tears while maintaining effective direction switching capability.
2Adaptability or versatility
If the guide member is positioned to guide bills in the branch direction, then direction switching is enabled, but the guide member fails to hold the superficial area of bills, causing them to lean out of the conveying channel
Solution Approach 1:
The second guide member acts as an intermediary element positioned on the side of the branching path. It provides additional guidance support for bills transitioning to the branch direction without interfering with the primary conveying channel. This intermediary guide member ensures that bills with superficial tears are properly supported and directed, preventing them from leaning out, folding, or breaking during the direction switching process.

AI summary
A conveying direction switching apparatus includes a first and a second blade assembly, and auxiliary blades rotatably provided at a shaft. The auxiliary blades are arranged between the first and second blade assemblies. When conveying bills, the portions of the bills passing between the first and second blade assemblies in the longitudinal direction of the shaft are guided by the auxiliary blades toward the conveying direction of the bills. Thus, the conveying direction of the medium is appropriately switched.
