Solution Overview

Problem

Existing packaging devices for sanitary articles lack flexibility to handle a variety of package units differing in type or size, particularly when dealing with high production rates from production lines.

Innovation Solution

A device and method featuring a diverter with multiple outlet lines and control unit to alternately direct batches of articles to packaging arrangements, allowing for flexible distribution of batches with varying counts, and using stackers with adjustable compartments or pockets to accommodate different sizes and quantities.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If packaging devices are designed for high production rates, then productivity is improved, but flexibility to handle diverse package units deteriorates

Engineering Contradiction:
Improveproduction rateVSAvoidflexibility
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

The patent implements dynamic batch size adjustment by allowing the control unit to set different batch sizes for different packaging arrangements in real-time. The system transitions from static packaging line configurations to dynamic, programmable batch distribution, enabling high-speed production while maintaining flexibility for diverse package units through software-controlled diversion ratios.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The diverter is designed as a universal control mechanism that can distribute articles to multiple packaging arrangements with varying batch sizes. Instead of requiring separate specialized equipment for different package types, a single diverter system with programmable control logic handles diverse packaging requirements, making the system multi-functional and adaptable to various package units.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Manufacturing precision

If packaging arrangements are configured for specific batch sizes, then manufacturing precision is improved, but adaptability to different package types deteriorates

Engineering Contradiction:
Improvebatch count accuracyVSAvoidpackage type variety
Core Design Contradiction:
Manufacturing precisionVSAdaptability or versatility

Solution Approach 1:

The system changes the parameter of batch size dynamically through programmable control. The control unit stores and executes sequences of batch sizes, allowing the same packaging arrangement to process different batch counts for different package types. This parameter variability is achieved through software configuration rather than hardware reconfiguration, maintaining precision while enabling adaptability.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The control unit pre-calculates and stores optimal batch size sequences for different packaging scenarios before production begins. By preparing the batch distribution plan in advance, the system ensures manufacturing precision is maintained while being ready to adapt to different package types without real-time adjustments or reconfiguration delays.

Inventive Principle:
Principle #10Preliminary action

3Adaptability or versatility

If multiple packaging arrangements are added to increase flexibility, then adaptability is improved, but device complexity deteriorates

Engineering Contradiction:
Improvepackage unit varietyVSAvoidsystem configuration
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Instead of adding specialized equipment for each package type, the patent uses a universal diverter system with programmable control that can manage multiple packaging arrangements. The control unit serves as a multi-functional brain that coordinates batch distribution across different packaging lines, reducing the need for additional complex hardware while maintaining high adaptability to various package units.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The control unit acts as an intermediary between the production line and multiple packaging arrangements. It mediates the distribution of articles by calculating optimal batch sizes and controlling the diverter accordingly, simplifying the overall system architecture by centralizing control logic rather than requiring complex direct connections between each component.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

The invention relates to a method and a device for packaging sanitary articles such as absorbent articles, like diapers, sanitary napkins, panty liners, incontinence pads or similar, wherein by means of at least one diverter (10) batches (A, B, C, D) of articles (5) are alternately directed towards M packaging arrangements (11, 12), each batch (A, B, C, D) comprising at least one article (5), and wherein the diverter (10) alternately directs batches (A, B, C, D) of articles (5) towards the packaging arrangements (11, 12) in a repeated series of MxN batches (A-C-B-D), with N>=2, wherein at least two of the N batches (A, B) of one series of MxN batches (A-C-B-D) directed towards the first packaging arrangement (11) differ in count.
