Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing labelling machines for containers, particularly bottles, face complexity and inefficiency in handling singularized labels, leading to increased structural complexity and operational challenges in managing the labelling process.
Innovation Solution
A labelling machine with a pantograph system and adjustable structure that allows for precise positioning of the labelling unit, integrating a cutting drum with a suctioned surface and a mechanism for cutting labels directly at the application point, simplifying label handling and adapting to various container sizes and types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If labels are cut and held on a drum with vacuum or mechanical gripping members, then labels can be applied to containers, but the labelling machine becomes more complex and larger in dimension
Solution Approach 1:
The patent extracts the label cutting operation from the traditional drum-based holding system and relocates it to occur immediately before label application. The cutting knife is positioned to singulate labels directly from the continuous web as they are being applied to containers, eliminating the need for complex vacuum drums or mechanical gripping members to hold singularized labels.
Solution Approach 2:
The patent merges the label cutting function with the label application process. The cutting knife is integrated into the labelling head assembly, so that cutting and application occur in a unified operation rather than as separate steps requiring separate components. This consolidation reduces the number of parts and simplifies the overall system.
2Ease of manufacture
If labels are cut at a remote position from the application point, then continuous web labels can be processed, but the handling of singularized labels becomes complicated
Solution Approach 1:
The patent performs the label cutting action immediately before application, rather than at a remote position. The cutting knife is positioned in the labelling head to singulate labels right at the point where they are needed, eliminating the complicated handling of pre-cut labels that would otherwise be required.
Solution Approach 2:
The patent introduces a buffer chamber as an intermediary element that receives the continuous label web and allows individual labels to be singulated and applied sequentially. The buffer chamber acts as a temporary holding space that simplifies the transition from continuous web to individual label application without requiring complex gripping mechanisms.
3Ease of operation
If self-adhesive labels are used with a base web, then labels can be applied easily, but the cost is higher compared to continuous web labels
Solution Approach 1:
The patent creates a labelling system that can handle both continuous web labels and self-adhesive labels with the same basic apparatus. The labelling head is designed to accommodate different label types, and the cutting mechanism can be adjusted or removed depending on the label type being used, providing universal functionality.
Solution Approach 2:
The patent changes the operational parameters of the labelling system to accommodate continuous web labels instead of self-adhesive labels. By adjusting the cutting mechanism and buffer chamber operation, the system can process different label types with the same hardware, allowing cost-effective continuous web labels to be used without requiring a complete system redesign.
