Robotic Label Roll Supply System for Automated Container Labeling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing container labeling systems require manual refilling of label rolls, which is ergonomically challenging and lacks automation, leading to inefficiencies and increased costs.
Innovation Solution
A robotic supply device with a multi-axis robot and roll storage unit that automatically loads label rolls from a storage unit to a labeling device, enabling high automation, flexibility, and continuous label tape supply to multiple labeling units without obstructing access or movement paths.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If manual refilling of label rolls is performed, then the labeling system can operate, but ergonomically challenging conditions and lack of automation occur
Solution Approach 1:
The robot cell autonomously performs the complete refilling process without human intervention. The robot automatically picks label rolls from the roll storage unit, transports them to the labeling device, and secures them in place. The system also automatically detects when rolls are depleted and initiates replacement, enabling self-service operation that eliminates manual refilling and its ergonomic challenges
Solution Approach 2:
The patent replaces the manual mechanical refilling process with an automated robotic system. The robot cell uses automated picking mechanisms, conveyor belts for transport, and automated securing mechanisms to replace the manual handling, carrying, and installation of label rolls that previously required human operators to perform ergonomically challenging tasks
2Extent of automation
If a mobile robot is positioned directly in front of the labeling unit for roll changing, then automation is achieved, but accessibility for maintenance and adjustment is impaired
Solution Approach 1:
The patent divides the automated label roll supply system into a separate robot cell that is spatially distinct from the labeling unit. The robot cell is positioned at a distance and connected via a tape guide bridge, creating functional segmentation that allows the labeling unit to be accessed for maintenance while the robot operates independently in its own cell. This spatial segmentation resolves the conflict between automation and accessibility
Solution Approach 2:
The patent introduces a tape guide bridge as an intermediary component that connects the robot cell to the labeling unit. This intermediary allows the robot to supply label rolls from a distant position without requiring direct access to the labeling unit's operational area. The tape guide bridge mediates the transfer of label tape between the two systems, enabling automation while preserving full accessibility to the labeling unit for maintenance and adjustment work
3Measurement precision
If specialized automated individual devices are used for each task, then precision is improved, but device complexity and costs increase
Solution Approach 1:
The patent employs a single multi-axis robot that performs multiple functions: picking label rolls from storage, transporting them to the labeling device, securing the rolls in place, and detecting when rolls are depleted. This universal robot replaces what would otherwise require multiple specialized devices, reducing overall system complexity while maintaining high precision through the robot's advanced control capabilities and programmable movements
