Diversion Mechanism Sloping Top for Drooping Check Jamming
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Check processing devices often experience media jamming due to drooping or bent checks colliding with the diversion unit in the transportation path, especially when wide or crumpled checks are processed.
Innovation Solution
A diversion mechanism with sloping guide surfaces and a top that connects the edges of these surfaces, allowing drooping checks to ride over the diversion unit without collision, featuring a convex curve for smooth guidance and a mirror-surface finish to prevent jamming.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional diversion unit with flat top is used, then the structure is simple, but drooping checks collide with the diversion unit causing jams
Solution Approach 1:
The diversion unit top is designed with a curved surface that slopes upward from the lever top toward the downstream end. This curvature allows drooping checks to ride along the sloped surface rather than collide with a flat top, guiding them smoothly into the appropriate branch path without causing jams.
Solution Approach 2:
The solution adds a dimensional aspect to the diversion unit top by introducing a slope in the upstream-downstream direction. Instead of a two-dimensional flat surface, the top becomes a three-dimensional sloped surface that provides a gradual transition for drooping checks, enabling them to clear the diversion unit without collision.
2Reliability
If the diversion unit top is made sloped to guide drooping checks, then checks can ride over without collision, but the manufacturing precision requirements increase
Solution Approach 1:
The curved surface of the diversion unit top is defined by specific geometric parameters including the slope angle in the upstream-downstream direction and the curvature radius. By optimizing these parameters, the design achieves effective guidance of drooping checks while maintaining manufacturability and avoiding excessive precision requirements.

AI summary
A check processing device conveys checks into branch paths without the check jamming. The downstream end of the check transportation path 7 of the check processing device 1 is split by a diversion unit 18 into first and second branch paths 11 and 12. The diversion unit 18 has diversion unit guide surfaces 18a and 18b that diverge to the right and left, and a diversion unit top 18c that connects the top edges of the diversion unit guide surfaces 18a and 18b. A branch switching lever or flapper 19 is located at the branching position A. The diversion unit top 18c slopes upward from the lever top 19c in the diversion direction on both right and left sides, and also slopes upward from the top edges of the diversion unit guide surfaces 18a and 18b perpendicularly to the diversion direction. If a check 6 with a drooping top is advanced to the branching position A, the drooping portion is guided by the diversion unit top 18c up and over the diversion unit 18, thereby enabling the check 6 to enter the first or second branch path 11 or 12 without colliding with the diversion unit 18.
