Stationary Holding Frame for Dynamic Receiving Bag in Banknote Stacking

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing apparatuses for stacking financial documents, such as banknotes, in transport containers do not allow for easy and secure removal of security bags after automatic filling, especially when used in value note machines, and often require complex manual operations.

Innovation Solution

A stationary holding frame is used to accommodate a receiving bag within the entry area of the machine, allowing the bag to grow with the stack length and be easily closed using welding or adhesive bonding, enabling the bag to be used independently or within a cassette, facilitating automatic filling and removal.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If security bags are used as transport containers for financial documents, then removal and reuse becomes difficult, but using traditional cassettes increases device complexity and requires complex manual operations for closing and stacking

Engineering Contradiction:

Improveremoval and reuse of security bagsVSAvoidclosing and stacking elements

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent extracts the closing function from complex mechanical stacking elements and implements it through simple welding or adhesive bonding of the bag material itself. The bag material is designed with self-closing capability through these joining methods, eliminating the need for separate closing devices and making removal straightforward.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent changes the closing mechanism from mechanical (complex stacking elements) to thermal or chemical (welding or adhesive bonding). This parameter change in the closing method simplifies the overall device structure while maintaining secure closure of the security bags.

Inventive Principle:

Principle #35Parameter changes

2Adaptability or versatility

If the receiving bag length is fixed, then manufacturing is simpler, but it cannot accommodate varying stack lengths of financial documents

Engineering Contradiction:

Improveaccommodation of various stack lengthsVSAvoidreceiving bag production

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The patent implements a dynamic receiving bag system where the bag length can be adjusted to match the stack length of financial documents. The holding frame structure allows the receiving bag to be positioned at different lengths, enabling adaptation to varying document volumes while maintaining a relatively simple manufacturing process for the base bag component.

Inventive Principle:

Principle #15Dynamics

3Ease of operation

If the holding frame is made stationary for simplicity, then device complexity is reduced, but the receiving bag cannot be removed easily after filling

Engineering Contradiction:

Improveremoval of receiving bag after fillingVSAvoidholding frame structure

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent segments the holding frame into a stationary support structure and a removable receiving bag component. The stationary holding frame provides structural support and positioning, while the receiving bag is designed as a separate, removable element that can be easily detached after filling, achieving both structural stability and operational ease.

Inventive Principle:

Principle #1Segmentation

4Productivity

If manual closing operations are used for security bags, then device complexity is reduced, but productivity and automation capability decrease

Engineering Contradiction:

Improveautomatic filling and closing operationVSAvoidautomatic closing mechanism

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent replaces complex mechanical closing mechanisms with thermal welding or chemical adhesive bonding methods. These substitution methods enable automatic closing operations as part of the filling process, significantly improving productivity and automation capability while actually reducing overall device complexity compared to mechanical closing systems.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

An apparatus for stacking financial documents, in particular banknotes. The financial documents (BN) are stacked upright in a stacking area on a stacking surface, and the stacking operation is terminated when a predetermined stack length is reached. The stack formation takes place in a receiving bag (14) which is stationarily held by a holding frame (10) in the entry area of the financial documents (BN) and which forms a stock (15) around the circumference of the holding frame (10). With increasing stack length, receiving bag material is automatically taken from the stock (15) so that the length of the receiving bag (14) continuously adapts to the length of the value note stack (31). At the end of the stacking operation the receiving bag (14) is closed at its opening, e.g. by welding, and can subsequently be removed from the stacking area and can be used as a transport container or, respectively, a security bag.
