Solution Overview

Problem

Existing labeling machines face significant downtimes and production losses due to the need for frequent changes in labeling tasks, particularly when handling different containers with varying shapes and label materials, as well as the restriction of free space on the machine's circumference by supporting elements like cams and cladding.

Innovation Solution

The machine's non-rotating control means and cam tracks are supported by a torque mechanism, allowing the rotary table to be rotated freely and enabling the arrangement of interchangeable treatment stations without structural constraints, thus creating a spacious peripheral area for flexible station placement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If non-rotating control means and cam tracks are permanently arranged on the labeling machine, then the machine can perform stationary control functions, but the free peripheral area for treatment stations is reduced

Engineering Contradiction:
Improvecontrol function stabilityVSAvoidfree peripheral area
Core Design Contradiction:
ReliabilityVSArea of stationary object

Solution Approach 1:

The machine structure is segmented into rotating treatment stations and a stationary control unit. The control means and cam tracks are separated from the rotating peripheral area and concentrated in a dedicated stationary control unit, allowing treatment stations to occupy the full peripheral circumference while control functions remain stable and stationary.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The control means are relocated from the two-dimensional peripheral arrangement to a centralized stationary control unit, effectively moving control functions to a different spatial dimension (center vs. periphery) and eliminating the conflict between control structure space and treatment station space.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Adaptability or versatility

If interchangeable treatment stations are arranged on the machine periphery, then adaptability to different labeling tasks is improved, but changeover time increases due to alignment requirements

Engineering Contradiction:
Improvelabeling task flexibilityVSAvoidchangeover time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The treatment stations are pre-equipped with standardized docking interfaces and alignment features that automatically engage with the rotary table during the changeover process. This preliminary design of standardized connections eliminates the need for time-consuming manual alignment operations when exchanging stations.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

Manual alignment operations are replaced by automated mechanical docking mechanisms. The standardized interfaces and automatic engagement systems substitute for manual positioning, significantly reducing the time required to exchange treatment stations while maintaining precision.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Stability of the object's composition

If the rotary table is constrained by supporting elements and structural components, then the machine structure is stable, but the freedom of arrangement for treatment stations is limited

Engineering Contradiction:
Improvestructural stabilityVSAvoidstation arrangement freedom
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The structural support functions are segmented and concentrated in the stationary control unit and base structure, while the rotary table is designed as a separate, minimally constrained component. This segmentation allows the rotary table to rotate freely with treatment stations positioned at any angular position without structural interference.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Supporting elements and structural components are extracted from the rotary table and relocated to the stationary control unit and machine base. This extraction eliminates constraints on the rotary table, allowing treatment stations to be arranged and positioned freely around the entire circumference.

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

The processing machine for bottles, tins or ampoules has e.g. labeling and printing units (8) mounted around it. The section of its periphery oriented away from the feed- and unloading-table (1) is free from supports, allowing the position of the processing units to be adjusted.
