Flat Article Packaging Blanks for Faster Reel-Fed Wrapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packaging machines for flat articles, particularly ceramic tiles, face limitations in production rate and durability due to the use of two-layer packaging material, leading to potential damage and frequent reel replacements, which result in machine downtime and operational inefficiencies.
Innovation Solution
A packaging method and apparatus that utilizes a feeding system to efficiently manage reels of packaging material, including a die-cutting machine to form blanks, and a packaging apparatus that wraps articles with pairs of blanks to protect edges and corners, enhancing production speed and reducing material waste.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If packaging material with only two layers of cardboard is used to reduce material quantity and storage volume, then the amount of packaging material used is reduced and storage volume is decreased, but the durability and resistance to damage from sharp edges are compromised
Solution Approach 1:
The patent applies composite materials by combining a first cardboard layer with a foam layer having elastomeric properties. This composite structure provides both the reduced material quantity benefit and the enhanced durability needed to resist damage from sharp edges during high-speed packaging operations.
Solution Approach 2:
The patent changes the physical parameters of the packaging material by incorporating a foam layer with specific elastomeric properties. This parameter change enables the material to be more resistant to tearing and damage while maintaining flexibility for winding and high-speed operation.
2Productivity
If conveying speed is increased to improve production rate, then productivity is improved, but the risk of damaging the packaging material increases due to greater stresses during wrapping
Solution Approach 1:
The patent applies beforehand cushioning by incorporating a foam layer with elastomeric properties into the packaging material structure. This cushioning effect is built into the material itself, allowing it to absorb stresses during high-speed conveying and wrapping operations without tearing or damaging the material.
Solution Approach 2:
The composite structure of cardboard combined with elastomeric foam provides both the structural integrity needed for high-speed operation and the flexibility required for successful wrapping around articles.
3Volume of stationary object
If reels of packaging material are used instead of sheets to reduce storage volume, then storage space is optimized, but frequent reel replacements are required leading to machine downtime
Solution Approach 1:
The patent enables continuity of useful action by designing a reel feeding system that maintains continuous operation during reel transitions. The automated reel replacement process minimizes interruptions, allowing the packaging operation to continue with minimal downtime and maintaining production efficiency.
4Ease of operation
If automated reel feeding system is implemented to reduce manual intervention, then ease of operation is improved and machine downtime is reduced, but device complexity increases
Solution Approach 1:
The patent applies self-service by implementing an automated reel feeding system that performs reel replacement and material feeding without manual intervention. The system serves itself by automatically detecting when reels need replacement and executing the changeover process, thereby improving ease of operation despite the increased device complexity.
