ATM Cash Cassette Spring-Loaded Retraction Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cash cassette designs for ATMs require a drive unit in separating and stacking modules for note handling, making them costly and complex, especially for pure payout machines where no note insertion is needed, limiting their use and increasing expenses for second-order cash cycle management.
Innovation Solution
Incorporating an elastic element, such as a torsion spring, to automatically move the retraction element between pivoted and retained positions without the need for a drive unit, allowing universal use in deposit, payout, and recycling ATMs by ensuring the retraction element is in the correct position for note handling without additional mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a drive unit is included in the separating and stacking module to move the retraction element, then the retraction element can be moved between retained and pivoted positions for note handling, but the device complexity and cost increase
Solution Approach 1:
The retraction element is designed to move automatically between retained and pivoted positions using its own weight and the elastic force of an integrated spring, without requiring an external drive unit. The spring is connected to the retraction element and provides the necessary force to return it to the retained position after it has been pivoted away, enabling self-service operation
Solution Approach 2:
The retraction element transitions from a static fixed position to a dynamic movable position. It can be pivoted away from the note stack to allow note insertion/removal, then automatically returns to its original position using the spring mechanism, creating a dynamic system that adapts to operational needs without complex control
2Adaptability or versatility
If a drive unit is required in the separating module, then the cash cassette can be used in recycling ATMs with note insertion, but it cannot be used in pure payout machines without increasing their cost
Solution Approach 1:
The retraction element with integrated spring provides self-service movement between positions, eliminating the need for a drive unit in the separating module. This self-powered mechanism works universally in both recycling ATMs and pure payout machines, enhancing adaptability without requiring different configurations
Solution Approach 2:
The cash cassette design with the spring-driven retraction element creates a universal solution that functions in multiple ATM types (recycling ATMs, pure payout machines, and deposit machines) without requiring different drive unit configurations. The separating module becomes simpler while maintaining versatility across different application scenarios

AI summary
The invention relates to a device (10) for handling banknotes, comprising at least one cash box (14a to 14d) for receiving banknotes and at least one singulating and/or stacking module (16a to 16d) for removing banknotes and/or for feeding banknotes to the cash box (14a to 14d). The singulating and/or stacking module (16a to 16d) and the cash box (14a to 14d) are disposed separately from each other. The cash box (14a to 14d) comprises a retraction element (34) disposed in a tilted position such that banknotes can be fed to and/or removed from the cash box (14a to 14d) through an opening (36) of the cash box (14a to 14d) by means of the singulating and/or stacking module (16a to 16d). In a retaining position, the retraction element (34) is disposed such that no banknotes can be fed into or removed from the cash box (14a to 14d). The cash box (14a to 14d) comprises an elastic element (58) retaining the retraction element (34) in the tilted position.
