Dog-leg Bill Press for Stable Cash Accumulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bill deposit/withdrawal machines are complicated in configuration due to the need for a tilting mechanism and retreating mechanism for the reject bill stopper, leading to potential poor delivery of rejected bills when the first bill press rotates 90 degrees, causing the bills to fall.
Innovation Solution
A bill deposit/withdrawal machine with a dog-leg shaped bill press that reciprocates between the separation/delivery means and the accumulating tongue piece roller, where the bill press is turned to incline its supporting face towards the accumulating tongue piece roller to guide bills stably into the conveying path.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a tilting mechanism and retreating mechanism are provided for the first bill press and reject bill stopper, then the rejected bills can be delivered, but the configuration becomes complicated
Solution Approach 1:
The patent removes the complex tilting mechanism and retreating mechanism from the conventional design. Instead, it extracts only the essential function of guiding rejected bills to the delivery position by using a simplified bill press structure with a dog-leg shape that inherently guides bills without requiring additional mechanisms.
Solution Approach 2:
Rather than making the bill press tilt or the stopper retreat to deliver rejected bills, the patent inverts the approach by designing the bill press with a fixed dog-leg shape that naturally directs bills to the correct position through its geometry alone, eliminating the need for complex movement mechanisms.
2Productivity
If the first bill press rotates by 90 degrees to a horizontal state, then rejected bills can pass over it, but the bills may fall causing poor delivery
Solution Approach 1:
The dog-leg shape of the bill press is designed in advance with a specific inclination angle that pre-establishes the correct trajectory for rejected bills. This preliminary geometric configuration ensures that bills are guided smoothly to the delivery position without falling, eliminating the need for rotation mechanisms while maintaining reliable delivery.
3Device complexity
If the bill press is simplified without tilting or retreating mechanisms, then the structure is simplified and costs reduced, but the ability to guide bills stably may be compromised
Solution Approach 1:
The bill press is designed with a dog-leg shape that creates a localized inclined surface at a specific position. This local geometric feature provides the necessary guiding function for bills without requiring the entire bill press structure to be complex or movable, thus maintaining simplicity while ensuring reliable bill guidance and payout.
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
This configuration simplifies the structure, reduces costs, and ensures stable payout of bills to the customer by preventing them from falling during accumulation.
Implementation Method 1
the rejected bills may fall. For this reason, there is a problem in that poor delivery of the rejected bills may be caused

AI summary
Provided is a means for stably accumulating the bills to be paid out to a customer. A bill press (26) has a dog-leg shape composed of a supporting face (26a) facing bills and an inclined face (26b) inclined in a direction away from the bills above the supporting face (26a), has two sliding pins (30) lined up along a movement direction on a side face thereof, and has a sliding groove (35) at the side of the bill press (26). A bent portion (35a) is provided at one end of the sliding groove (35) on the side of an accumulating tongue piece roller (28). When the bills to be paid out to a customer are accumulated in a bill deposit/withdrawal unit (10), the bill press (26) turns so that the sliding pins (30) on the side of the accumulating tongue piece roller (28) enter the bent portion (35a), and thereby the supporting face (26a) is inclined toward the accumulating tongue piece roller (28).
