Bill Pushing Member Reciprocating Motion for Compact Payout
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bill receiving and payout devices for vending machines or money exchangers are bulky due to the need for large-scale construction and separate mechanisms for handling different denominations, making them inefficient and complex.
Innovation Solution
A compact bill receiving device design featuring a central bill passage with a bill pushing member for reciprocating motion, allowing bills to be directed into separate receiving chambers and efficiently paid out using a bill conveying apparatus and a rubber cam roller for reliable extraction of the rearmost bill.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a bill receiving device is designed to pay out received bills or stack bills of different denominations separately, then the device achieves specialized functionality, but the construction becomes large-scale and complex
Solution Approach 1:
The single bill receiving chamber is designed to perform multiple functions: receiving bills, stacking them, and paying them out. The bill pushing member can move in both directions to either stack bills in the same chamber or push them to the payout mechanism, eliminating the need for separate receiving structures for different denominations
Solution Approach 2:
The patent combines the bill receiving and bill payout functions into a single integrated chamber. The bill pushing member serves dual purposes by being able to push bills either for stacking within the chamber or for payout through the outlet, merging what would traditionally require separate mechanisms
2Adaptability or versatility
If a large-scale bill payout mechanism is used to pay out received bills, then the payout function is achieved, but the device requires large-scale construction
Solution Approach 1:
The payout mechanism is extracted as a separate, compact module within the larger bill processing system. The bill pushing member can push bills to a specific location where they are accessible to the payout mechanism, allowing the payout function to be implemented with minimal additional space
Solution Approach 2:
The bill pushing member moves in both horizontal directions along the longitudinal axis of the chamber, utilizing the length dimension efficiently. This bidirectional movement allows the same mechanism to serve both stacking and payout functions without requiring additional vertical or lateral space

AI summary
A method of receiving and paying out bills including the steps of providing a bill passage in about the central portion of an elongate casing that extends along one side of a bill receiving chamber having a bill payback: outlet; providing a bill conveying apparatus for conveying a bill delivered to said bill passage to a predetermined position for receiving it; utilizing a bill pushing member being capable of moving in a reciprocating motion across said passage to bill receiving chamber when the bill located at said predetermined position in said passage to be received, effects receiving of the bill by pushing it with a surface of said bill pushing member across from said passage; disengaging the rearmost bill from said bill receiving chamber by operating bill extracting apparatus in the reverse direction by a predetermined amount while said bill pushing member is activated causing it to extract away and pull out from a rearmost bill leading edge retainer which holds the remaining bills in position; and, operating the extracting apparatus in the forward direction to transport said extracted rearmost bill through said bill payback outlet to said bill conveying apparatus which is operated in reverse to direct it to the customer.
