Innovation Solution

A trimming system with a ring-shaped transport device and abrasive tools mounted on sliding frames, equipped with detectors and drive assemblies, allows simultaneous and precise trimming of all edges while the articles are in motion, adapting to edge imperfections in real-time.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If multiple transverse trimming stations are used to finish several articles simultaneously, then productivity is improved, but device complexity and space requirements increase considerably

Engineering Contradiction:
Improvetrimming throughputVSAvoidnumber of trimming stations
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent employs a robotic manipulator with dynamic positioning capabilities that can move between different articles and trim them sequentially. The robotic system adapts its position and orientation in real-time based on article location, replacing the need for multiple fixed trimming stations. This dynamic approach maintains high productivity while reducing overall system complexity and space requirements.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

A single robotic manipulator is designed to perform trimming operations on multiple articles at different positions and orientations. The robotic system serves as a universal trimming device that can handle both longitudinal and transverse edges of various articles along the conveyor, eliminating the need for dedicated trimming stations for each article position.

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

2Manufacturing precision

If traditional fixed trimming stations are used, then manufacturing precision is maintained, but productivity decreases due to machine stops

Engineering Contradiction:
Improveedge trimming accuracyVSAvoidproduction speed
Core Design Contradiction:
Manufacturing precisionVSProductivity

Solution Approach 1:

The robotic manipulator operates continuously alongside the moving conveyor belt, trimming articles as they pass by without requiring the conveyor to stop. The robotic system maintains continuous trimming action by positioning itself appropriately for each article, ensuring both high productivity and manufacturing precision through uninterrupted operation.

Inventive Principle:
Principle #20Continuity of useful action

Solution Approach 2:

The system incorporates detectors that monitor article positions and dimensions in real-time, providing feedback to the robotic manipulator and control system. This feedback mechanism enables the robotic system to adjust its trimming parameters dynamically, maintaining manufacturing precision while operating continuously at high speed alongside the moving articles.

Inventive Principle:
Principle #23Feedback

3Device complexity

If abrasive tools are positioned fixedly, then device complexity is reduced, but adaptability to edge imperfections and alignment errors decreases

Engineering Contradiction:
Improvepositioning system complexityVSAvoidtolerance to misalignment
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The robotic manipulator provides dynamic positioning and orientation capabilities, allowing the abrasive tools to adapt to variations in article position, orientation, and edge imperfections. The robotic system can adjust its degrees of freedom in real-time to compensate for misalignment errors, providing high adaptability without requiring overly complex fixed positioning mechanisms for each tool.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

Detectors mounted on or near the robotic manipulator continuously monitor article positions, orientations, and edge characteristics, providing feedback that enables real-time adjustments by the robotic control system. This feedback mechanism allows the system to adapt to alignment errors and edge imperfections dynamically, maintaining trimming quality without requiring pre-calibrated complex positioning systems.

Inventive Principle:
Principle #23Feedback
