Banknote Cassette Handling Device Segmentation

Solution Overview

Problem

Existing banknote handling systems require feeding and separating elements to be integrated within the container, increasing weight, complexity, and transport effort, while also occupying space that could be used for storage, and necessitating exact positioning for reliable operation.

Innovation Solution

A single sheet handling device where feed and separating elements are separate from the container, allowing for a simpler container design, reduced weight, and easier exchange, with active drives for flap movement to control feeding and separating operations, and engagement elements for safe operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If feeding and singulation elements are integrated within the container, then reliable banknote transport is achieved, but container weight increases and storage space decreases

Engineering Contradiction:

Improvebanknote transport reliabilityVSAvoidcontainer weight

Core Design Contradiction:

ReliabilityVSWeight of moving object

Solution Approach 1:

The system is divided into two independent parts: the container (cassette) for storing banknotes and the feeding/singulation device for handling banknotes. The container can be separated from the handling device, allowing the container to be lightweight and simple while the feeding/singulation elements remain in the main device.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The feeding and singulation elements are extracted from the container and placed in the main handling device. This extraction reduces container weight and complexity while maintaining reliable banknote transport through the separated feeding device.

Principle #2Taking out (Extraction)

2Reliability

If feeding and singulation elements are integrated within the container, then reliable banknote transport is achieved, but container complexity increases

AI summary

The invention relates to a single-sheet handling device (14a to 14d, 30, 200, 252, 270, 350) for feeding and dispensing rectangular single sheets (38) into and from a container (12a to 12d). These rectangular single sheets can, in particular, be banknotes (38). The single-sheet handling device (14a to 14d, 30, 200, 252, 270, 350) has a feeding device comprising feeding elements for feeding single sheets (38) one by one and for depositing these single sheets (38) in a stack (36) of single sheets in the container (12a to 12d). Furthermore, the single-sheet handling device has a singulation device comprising singulation elements for removing single sheets (38) from the stack (36) of the container (12a to 12d) one by one. The feed elements and the singulation elements are arranged separately from the container (12a to 12d).
