Document Processor Cam Flag Mechanism for One-Handed Sorting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Document processing machines lack advanced features for efficient sorting and processing of documents based on pre-programmed criteria, such as currency value or processing quality, and do not facilitate easy operation with one-handed use.
Innovation Solution
A document processing apparatus with a pivotably arranged output bin selector and a cam member system that automatically adjusts the flag's orientation within the input hopper to facilitate document sorting and processing, allowing for one-handed operation and automatic movement of documents through the system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a manual flag adjustment system is used in the input hopper, then the device complexity is reduced, but the ease of operation deteriorates because two-handed operation is required
Solution Approach 1:
The cam member is pre-configured with specific cam surfaces that automatically perform the flag adjustment action when activated by a single button press, eliminating the need for manual two-handed operation while maintaining operational simplicity
Solution Approach 2:
The cam member mechanism automatically adjusts the flag position in response to button activation, making the system self-adjusting without requiring user manipulation of multiple components, thereby enabling one-handed operation
2Productivity
If documents are processed without automatic sorting criteria, then the device complexity is lower, but the productivity decreases due to manual sorting requirements
Solution Approach 1:
Sorting criteria are pre-programmed into the control system, allowing documents to be automatically sorted and directed to appropriate output bins without manual intervention, thereby increasing productivity while keeping the physical sorting mechanism simple
Solution Approach 2:
Manual sorting operations are replaced with an automated control system that uses pre-programmed criteria to direct document flow, increasing processing efficiency without requiring complex mechanical sorting hardware
3Adaptability or versatility
If the output bin selector is fixed rather than pivotable, then the device complexity is reduced, but the adaptability deteriorates because it cannot accommodate different document sorting scenarios
Solution Approach 1:
The output bin selector is designed with pivotable movement capability, allowing it to dynamically adjust between different output bins based on sorting criteria, providing adaptability while maintaining a simple rotational mechanism rather than complex multi-axis positioning

AI summary
A sub-assembly of a document processor that routes at least one document from an input hopper, along a document path and to an output bin is disclosed. The document processor includes a flag movably-arranged within the input hopper to/from a closed orientation and an open orientation; a rod fixed to and extending from the flag, wherein the rod includes an outer surface; a cam member including a camming surface, wherein the camming surface is communicatively-coupled to the outer surface of the rod; a driven shaft connected to the cam member, wherein the cam member further includes a one-way clutch, wherein the driven shaft extends through the one-way clutch; and a feed motor connected to the driven shaft. A method for operating the sub-assembly is also disclosed.
