Solution Overview

Problem

Existing machines for aligning and labeling grouped vessels, such as bottles, face difficulties in axial clamping and lack flexibility to handle more than two vessels, leading to instability and inefficiency in the labeling process.

Innovation Solution

A centering unit with pre-centering and final centering means that can be raised and lowered, along with partial centering means, allows for precise alignment and stabilization of vessels at different heights, enabling flexible adaptation to various vessel configurations, including twin packs, quadro packs, and six packs, using pneumatic control for independent operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If a single centering bell is used to clamp vessels axially, then the vessels are held in position, but the alignment is unstable and difficult to achieve

Engineering Contradiction:
Improvealignment precisionVSAvoidalignment stability
Core Design Contradiction:
Manufacturing precisionVSReliability

Solution Approach 1:

The centering bell is divided into multiple independent centering elements (at least two) that can be adjusted separately. Each centering element can be individually positioned radially and axially to contact different vessels in the group, enabling precise alignment of multiple vessels with each other while maintaining stability through distributed contact points rather than a single clamping location

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If the centering device is designed for two vessels, then alignment is achieved, but the device cannot handle more than two vessels

Engineering Contradiction:
Improvevessel group flexibilityVSAvoidcentering device structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The centering device incorporates multiple adjustable centering elements that can be independently positioned radially and axially, allowing the same device structure to accommodate and align different numbers of vessels (pairs, triplets, quadruplets, etc.). This universal design enables a single device to handle various vessel group configurations without requiring different specialized tools for each case

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

3Manufacturing precision

If multiple centering elements are used to improve alignment, then positioning precision increases, but the device complexity increases

Engineering Contradiction:
Improvevessel positioning accuracyVSAvoidcentering mechanism complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The centering elements are designed with adjustable mechanisms that allow radial and axial positioning to be modified during operation. This dynamic adjustability enables precise alignment for different vessel configurations while maintaining a relatively simple base structure, as the complexity is managed through controlled adjustability rather than fixed complex mechanisms

Inventive Principle:
Principle #15Dynamics
