Linerless Label Affixing Device Dynamic Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional label affixing devices struggle to accurately position linerless labels of varying lengths on articles, leading to inconsistent placement, where labels may protrude or have uneven spacing, affecting the appearance and consumer appeal of products on store shelves.
Innovation Solution
A label affixing device with a label issuing unit that feeds and cuts linerless labels to a prescribed length, and a controlled affixing unit that adjusts its movement based on the label length to ensure correct positioning, using a label length detector and affixing position information storage to maintain precise alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If linerless labels of varying lengths are used to accommodate different printing requirements, then the adaptability of the labeling system is improved, but the positioning precision deteriorates causing labels to be affixed at incorrect positions
Solution Approach 1:
The label affixing device dynamically adjusts its operation based on the actual label length detected. The control unit receives detection signals about the label length and automatically modifies the affixing position and timing, transforming a static positioning system into a dynamic one that adapts to varying label lengths while maintaining precise positioning.
Solution Approach 2:
A label length detector is integrated into the system to provide real-time feedback about the actual label length. This feedback loop allows the control unit to receive information about label variations and automatically compensate by adjusting the affixing position, ensuring precise positioning despite length variations.
2Device complexity
If the label affixing device uses fixed positioning for labels, then the device complexity is reduced, but the positioning accuracy deteriorates when label lengths vary
Solution Approach 1:
The system incorporates a label length detector that provides feedback about actual label dimensions. This feedback enables the control unit to automatically adjust positioning parameters without requiring complex manual intervention or overly complicated mechanical positioning systems.
Solution Approach 2:
The patent replaces complex mechanical positioning adjustments with an automated control system that uses detection signals to electronically adjust the affixing position. This substitution of mechanical complexity with electronic control achieves high positioning accuracy while keeping the overall device complexity manageable.
3Adaptability or versatility
If labels are cut to different lengths based on printing requirements, then the versatility of the labeling system is improved, but the uniformity of label placement deteriorates
Solution Approach 1:
The affixing system dynamically adapts its positioning based on the detected label length. Rather than using fixed positioning that would compromise uniformity, the system continuously adjusts the affixing location to maintain consistent placement quality across labels of different lengths.
Solution Approach 2:
The label length detector provides critical feedback that enables the control unit to compensate for length variations. This feedback mechanism ensures that each label is affixed at the correct position relative to its specific length, maintaining uniformity in placement quality despite variations in absolute label dimensions.
