Cash Cassette Coupling Retracting Flap and Movable Bottom Element
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In full cash cassettes, the force exerted by the press-on carriage may not be sufficient to move the entire value note stack, leading to issues during withdrawal or deposit, as the retracting flap's slanted position requires notes to be upright and aligned correctly for proper operation.
Innovation Solution
A movable bottom element is mechanically coupled to the retracting flap, ensuring it moves synchronously with the flap between positions, eliminating the need for the press-on carriage to move notes relative to the bottom unit, thus ensuring reliable feeding and removal of notes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the press-on carriage exerts force to move the value note stack during retracting flap movement, then the notes can be fed or removed, but the force may not be sufficient when the cash cassette is very full, causing notes to not be properly upright or aligned
Solution Approach 1:
The bottom unit is divided into a fixed bottom element and a movable bottom element. The movable bottom element can be displaced independently to assist in moving the value note stack during retracting flap movement, reducing the burden on the press-on carriage and ensuring reliable note movement even when the cassette is full.
Solution Approach 2:
The movable bottom element acts as an intermediary between the fixed bottom unit and the value note stack. It facilitates the movement of notes by providing a movable support surface that can be displaced to assist the press-on carriage in uprighting and aligning the notes during the retracting flap's movement.
2Reliability
If the retracting flap is slanted in the swiveled-on position to retain notes, then the notes can be held in the receiving area, but the notes must be put upright which requires sufficient force that may not be available
Solution Approach 1:
The bottom element is designed to be movable rather than fixed, allowing it to dynamically adjust its position during the retracting flap's movement. This dynamic capability enables the bottom element to assist in uprighting notes without requiring additional complex mechanisms, as the movement is coupled to the existing retracting flap motion.
3Productivity
If the press-on carriage moves notes relative to the bottom unit during retracting flap movement, then notes can be fed or removed, but this relative movement increases the risk of misalignment and feeding problems
Solution Approach 1:
The movable bottom element is extracted from the fixed bottom unit, allowing it to be displaced independently. This separation enables the bottom element to move with the value note stack during the retracting flap's movement, minimizing relative movement between the notes and their support surface, thereby reducing misalignment risks while maintaining automatic feeding and removal functionality.

AI summary
The invention relates to a cash cassette (10, 100, 200) comprising a bottom unit (18) on which the notes of value of the value note stack (16) stand. Further, a retracting flap (28) is provided which is movable between a retracting position and a swiveled-away position. The cash cassette (10, 100, 200) is designed such that a movable bottom element (40, 54) of the bottom unit (18) is coupled to the retracting flap (28) such that at least the movable bottom element (40, 54) is movable together with the retracting flap (28) between the retracting position and the swiveled-away position.
