Container Label Applicator Monitoring with Laser Displacement Sensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High-speed, complex, parallelized manufacturing processes for container labeling face challenges such as variability in label alignment, wrinkles, and loose parts due to operational conditions, which are difficult to detect and correct using conventional sensors mounted to system components.
Innovation Solution
A non-contact sensor, such as a laser sensor, measures the displacement of a deformable label applicator panel to generate distance profiles, allowing for real-time detection and correction of operational conditions, reducing variability and improving label application quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional sensors are physically mounted to system components (e.g., label applicator panel), then the system can detect operational conditions, but the physical mounting impacts the process and introduces additional variability
Solution Approach 1:
The patent introduces an intermediary optical system (laser source and sensor) that measures panel displacement without physical contact. The laser beam serves as a mediator between the panel position and the measurement system, allowing detection of operational conditions while eliminating the harmful effect of physical sensor mounting on the labeling process.
2Reliability
If manual inspection is performed by operators, then defects can be detected, but the process is time-consuming and troubleshooting is difficult
Solution Approach 1:
The system implements continuous automated feedback by measuring panel displacement in real-time during the labeling process. The sensor provides immediate data about operational conditions, enabling proactive adjustment before defects occur, rather than relying on delayed manual inspection and reactive troubleshooting.
Solution Approach 2:
The patent replaces the mechanical/manual inspection system with an optical measurement system. Instead of operators physically examining labeled containers, an automated optical sensor continuously monitors panel position and detects operational deviations, significantly reducing inspection time and enabling real-time process control.
3Productivity
If high-speed parallelized manufacturing is implemented, then productivity increases, but variability in label alignment and quality outages increase
Solution Approach 1:
The automated displacement measurement system provides continuous feedback on panel position during high-speed operation. This enables real-time detection and correction of variability sources, maintaining label alignment consistency even as manufacturing speed increases through parallelized processing.

AI summary
An apparatus is provided for improving the labelling process of containers. The apparatus includes a container carrier arranged in a travel lane. The travel lane has a downstream direction in which the carrier is movable. The apparatus also includes a deformable panel comprising a fixed end and a free end. The deformable panel is positioned angled to and intersecting the travel lane. The free end is more proximal to the travel lane than the fixed end. The apparatus also includes a displacement sensor measuring the displacement at the deformable panel. A method is also provided for detecting an operational condition of the apparatus.
