Solution Overview

Problem

Existing methods for filling security document cassettes, such as those used in ATMs, are inefficient as they result in documents being oriented differently, leading to issues with automatic removal due to misalignment of edges.

Innovation Solution

A device that includes a cassette receiving device, a gripping mechanism, a transport device, and a control unit to align and insert stacks of documents into cassettes, decoupling the filling process from the sorting process, using a formatting unit to align documents and a hold-down device to prevent documents from being pulled out during withdrawal.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a stack of security documents is placed into a cassette manually, then the risk of soiling or damaging the documents is reduced, but the filling process is time-consuming and labor-intensive

Engineering Contradiction:
Improvefilling speedVSAvoidhandling complexity
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

A finger element is introduced as an intermediary component between the gripping device and the security documents. This finger element inserts into the stack of documents and works in conjunction with the gripping device to securely hold and transport the documents into the cassette, enabling automated handling while protecting the documents from damage or soiling.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The gripping device is divided into multiple gripping elements that can independently engage with different parts of the document stack. This segmentation allows for more precise and gentle handling of the documents, enabling automated insertion without compromising document integrity.

Inventive Principle:
Principle #1Segmentation

2Manufacturing precision

If formatting devices are used to align document stacks, then filling accuracy is improved, but device complexity and cost increase

Engineering Contradiction:
Improvealignment accuracyVSAvoiddevice structure
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The finger element serves as a dual-purpose intermediary: it not only aids in gripping the documents but also functions as a formatting element that guides and aligns the document stack during insertion. This eliminates the need for separate formatting devices while maintaining alignment accuracy.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The gripping device and formatting functions are merged into a single integrated system. The finger element is attached to the gripping device, combining the functions of document engagement and alignment/formation in one component, thereby reducing overall device complexity.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

The invention relates to the filling of security document cassettes and, for this purpose, comprises a cassette receiving device for receiving a security document cassette and a gripping device for transporting a stack of security documents from a security document container into the security document cassette. Furthermore, the device optionally includes a formatting device for automatically aligning a stack of security documents removed from the security document container before it is placed into the security document cassette. In a preferred embodiment, a finger element is attached to the transport device of the gripping device, in addition to the gripping device itself, which is inserted before the security documents are placed into the security document cassette.
