Mobile Robot End Effector for Autonomous Label Roll Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for introducing label rolls into labeling machines are impractical and ergonomically unfavorable, leading to inefficient use of equipment and space, as they require frequent manual intervention and operator presence.
Innovation Solution
A mobile robot with a motorized vehicle unit and a multi-axle manipulator end effector that can grip label rolls externally or internally, allowing for autonomous movement and operation to change label rolls in labeling assemblies without human intervention, reducing the need for manual handling and optimizing space usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a mobile robot with multi-axle manipulator is used for label roll handling, then automation level and ergonomics are improved, but device complexity increases
Solution Approach 1:
The mobile robot is designed with a universal manipulator system that can perform multiple functions: gripping label rolls externally at the outer circumference, gripping roll cores internally, removing emptied roll cores, and positioning label rolls on roll plates. This multi-functionality reduces the need for multiple specialized devices while maintaining high automation levels.
Solution Approach 2:
The robot employs a dynamic multi-axle manipulator with adjustable degrees of freedom, allowing the end effector to adapt its gripping configuration based on the specific task—whether external gripping of label rolls or internal gripping of roll cores. This dynamic adaptability enables a single device to handle varied operations that would otherwise require multiple fixed-function devices.
2Ease of manufacture
If manual label roll handling is performed, then equipment cost is reduced, but operator presence is required and ergonomics worsen
Solution Approach 1:
The mobile robot autonomously performs label roll handling operations without requiring operator intervention. The robot navigates to the labeling machine, manipulates label rolls and roll cores using its end effector, and returns to its starting position automatically. This self-service capability eliminates the need for manual handling while maintaining cost-effectiveness through reduced labor requirements.
3Measurement precision
If label rolls are handled with internal grip only, then handling precision is improved, but external tasks like depositing on roll plates become difficult
Solution Approach 1:
The end effector is designed with dynamic gripping capability that can switch between internal gripping (for precision handling of roll cores) and external gripping (for depositing label rolls on roll plates or removing emptied cores). The manipulator system adjusts its configuration based on the specific task requirements, providing both precision and versatility.
Solution Approach 2:
The end effector serves multiple functions through its dual gripping modes: internal gripping for precise manipulation of roll cores during removal and installation, and external gripping for depositing label rolls onto roll plates and handling emptied roll cores. This universal design enables a single device to perform all label roll handling tasks.

AI summary
The invention relates to a mobile robot, to a supply system, and to a method for changing label rolls on a labeling assembly for labeling containers. The mobile robot accordingly comprises a vehicle unit for changing locations of the robot and a manipulator unit with a multi-axle manipulator and an associated end effector for manipulating label rolls. Because the end effector is designed to grip the outer circumference of the label rolls and emptied roll cores of label rolls so as to carry them, ergonomically problematic work steps when introducing label rolls can be accomplished exclusively by machine with a high degree of precision and in a material-saving manner.
