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

A magazine apparatus with autonomous positioning and splicing capabilities, utilizing an automated guided vehicle to deliver new reels and splicing units to ensure seamless reel replacement without manual intervention.

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 system performs preliminary actions by positioning a new reel in the auxiliary position and pre-splicing it to the current reel while the current reel is still in use. This allows the transition to occur without stopping production, as the splicing is prepared in advance during non-critical time periods.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The magazine apparatus introduces an intermediary auxiliary position between the reel in use and complete replacement. This intermediary state allows the new reel to be positioned and spliced without disrupting the continuous operation of the current reel, serving as a buffer that enables seamless transition.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If automated reel positioning is implemented, 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 system provides self-service by automatically positioning the new reel in the auxiliary position and performing the splicing operation without operator intervention. The magazine apparatus monitors and controls the entire reel replacement process, eliminating the need for manual positioning and splicing operations.

Inventive Principle:
Principle #25Self-service

3Loss of time

If reel splicing is automated, then loss of time is reduced, but device complexity increases

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

Solution Approach 1:

The splicing operation is performed as a preliminary action while the current reel is still in use. The new reel is spliced to the current reel in the auxiliary position before the current reel is exhausted, allowing the transition to occur without stopping production and minimizing time loss.

Inventive Principle:
Principle #10Preliminary action
