Solution Overview

Problem

Existing systems for labeling and handling reels of web material suffer from low flexibility and handling speed, negatively impacting the productivity of reel packaging lines.

Innovation Solution

A system comprising a first labeling robot and a second handling robot, equipped with anthropomorphic arms and centering systems, allows simultaneous labeling and handling of multiple reels by applying labels to the inner and outer surfaces, utilizing vacuum and pneumatic systems for label application and expandable gripping elements for reel manipulation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a single robot is used for both labeling and handling reels, then device complexity is reduced, but handling speed and productivity decrease

Engineering Contradiction:
Improvenumber of robotsVSAvoidhandling speed
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The system divides the reel processing function into two separate robots: a first robot dedicated to labeling operations and a second robot dedicated to handling and stacking operations. This segmentation allows each robot to specialize in its specific task, increasing overall handling speed and productivity while maintaining reasonable device complexity through functional division.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system combines multiple labeling machines (for inner and outer surface labeling) with the first robot, and integrates the second robot with stacking and packaging functions. This merging of multiple functions into coordinated robotic systems achieves high-speed processing while managing device complexity through integrated control.

Inventive Principle:
Principle #5Merging (Combining)

2Reliability

If multiple labeling machines are used for inner and outer surface labeling, then labeling completeness is improved, but device complexity and cost increase

Engineering Contradiction:
Improvelabeling completenessVSAvoidnumber of labeling machines
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The first robot is designed with multi-functionality, serving both as a labeling machine for inner and outer surfaces and as a handling device for reel positioning. This universal robot performs multiple labeling tasks that would traditionally require separate dedicated machines, reducing overall device complexity while maintaining labeling completeness.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The labeling function is segmented into inner surface labeling and outer surface labeling operations, performed by the first robot in sequence. This segmentation allows comprehensive labeling without requiring all labeling machines to operate simultaneously, managing device complexity through temporal rather than spatial separation.

Inventive Principle:
Principle #1Segmentation

3Manufacturing precision

If reels are processed one by one, then handling precision is maintained, but productivity decreases

Engineering Contradiction:
Improvehandling precisionVSAvoidprocessing speed
Core Design Contradiction:
Manufacturing precisionVSProductivity

Solution Approach 1:

The first robot performs preliminary labeling actions on reels while the second robot simultaneously performs handling and stacking actions on other reels. This preliminary action approach allows overlapping of operations, increasing productivity while maintaining precision through dedicated specialized robots for each task.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system establishes continuous useful action by having the first robot continuously label reels while the second robot continuously handles and stacks them. This continuous parallel operation maximizes productivity while each robot maintains its specific handling precision through specialized design and control.

Inventive Principle:
Principle #20Continuity of useful action
