Solution Overview

Problem

Current embossing roller replacement systems in tissue paper processing lines are not efficient enough, requiring longer downtimes and production losses due to the complexity and time-consuming nature of replacing embossing rollers, which limits operational flexibility and maintenance capabilities.

Innovation Solution

A magazine system for embossing rollers with integrated support seats and a guide system that allows for the selective movement of each seat to different stations, enabling quick extraction and insertion of single rollers, along with a handling member that supports the transfer of rollers between the magazine and the embossing device, allowing for continuous operation and increased roller interchangeability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If embossing rollers are replaced manually in traditional systems, then roller interchangeability is achieved, but replacement time and downtime increase significantly

Engineering Contradiction:

Improveroller interchangeabilityVSAvoidreplacement time

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The magazine is divided into multiple independent support seats (first support seat, second support seat, etc.) that can be individually accessed and operated. Each seat can hold a different embossing roller, allowing selective replacement without moving other rollers. The magazine itself is segmented from the main embossing device, enabling independent operation and quick roller exchange.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Multiple embossing rollers are pre-loaded into the magazine's support seats before the replacement operation begins. When a roller needs replacement, the system can immediately switch to a pre-positioned roller from the magazine, eliminating the need to search for or prepare replacement rollers during the replacement process.

Inventive Principle:

Principle #10Preliminary action

2Adaptability or versatility

If embossing rollers are replaced frequently to change patterns, then production versatility improves, but operational downtime increases

Engineering Contradiction:

Improveproduction versatilityVSAvoidoperational efficiency

Core Design Contradiction:

Adaptability or versatilityVSProductivity

Solution Approach 1:

The magazine system serves multiple functions: it stores multiple embossing rollers, provides quick access to different rollers, and enables rapid switching between patterns. The support seats are designed to accommodate different roller types, making the system universally applicable for various embossing patterns and production requirements.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The magazine is designed with movable components including a movable support seat that can be shifted between positions, and support seats that can be extracted and reinserted. This dynamic design allows rapid reconfiguration and roller replacement without requiring complete disassembly or complex manual operations.

Inventive Principle:

Principle #15Dynamics

3Quantity of substance

If a magazine system with multiple support seats is implemented, then roller storage capacity increases, but device complexity increases

Engineering Contradiction:

Improveroller storage capacityVSAvoidmagazine structure

Core Design Contradiction:

Quantity of substanceVSDevice complexity

Solution Approach 1:

The magazine structure is nested within or integrated with the embossing device framework. Multiple support seats are arranged in a compact configuration where they can be stacked or positioned in layers, maximizing storage capacity while minimizing the overall footprint and structural complexity of the magazine system.

Inventive Principle:

Principle #7Nested doll (Nesting)

4Ease of operation

If manual roller replacement procedures are used, then operational simplicity is maintained, but replacement speed decreases

Engineering Contradiction:

Improveoperational simplicityVSAvoidreplacement speed

Core Design Contradiction:

Ease of operationVSSpeed

Solution Approach 1:

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Inventive Principle:

Principle #15Dynamics

AI summary

The magazine for embossing rollers includes a plurality of support seats for embossing rollers, adjacent to one another according to an alignment direction. The magazine further includes a guide system for guiding the seats in a handling direction. The seats are provided with mutual connecting members so as to be connected to, and released from, one another.
