Solution Overview

Problem

Existing magazine apparatuses for packaging machines require significant operator intervention for reel changes, disrupting continuous production and increasing the need for manual handling.

Innovation Solution

An automated magazine apparatus with an autonomous positioning device, such as a laser-guided vehicle, facilitates the seamless replacement of packaging material reels, allowing continuous operation with minimal human intervention by using support devices and splicing units to manage reel transitions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If manual reel replacement is used, then device complexity is reduced, but productivity decreases due to production interruptions

Engineering Contradiction:
Improvecontinuous productionVSAvoidmagazine apparatus complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The magazine apparatus is divided into multiple independent support devices, each capable of holding and supplying reels autonomously. This segmentation allows one support device to be replaced or serviced while others continue operation, enabling continuous production without complete system shutdown.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system prepares replacement reels in advance by positioning them on standby support devices before they are needed. The splicing mechanism is pre-positioned and ready to connect incoming web material from replacement reels, minimizing interruption time when reel exhaustion occurs.

Inventive Principle:
Principle #10Preliminary action

2Ease of operation

If automated positioning devices are introduced, then ease of operation improves, but device complexity increases

Engineering Contradiction:
Improvereel replacement operationVSAvoidpositioning system complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The autonomous positioning device automatically detects reel positions, calculates optimal splicing locations, and executes positioning operations without human intervention. The system serves itself by using sensors and control algorithms to manage the complex positioning tasks, reducing operational burden while containing complexity within the automated system.

Inventive Principle:
Principle #25Self-service

3Loss of time

If manual handling is used, then device complexity is reduced, but loss of time increases due to operator intervention

Engineering Contradiction:
Improvereel change timeVSAvoidautomation system complexity
Core Design Contradiction:
Loss of timeVSDevice complexity

Solution Approach 1:

Manual mechanical operations of reel replacement and web splicing are replaced by an automated system comprising autonomous positioning devices, sensors, and controlled splicing mechanisms. This substitution eliminates the time-consuming manual steps of reel removal, positioning, and connection, dramatically reducing reel change time despite the added system complexity.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
