Solution Overview

Problem

Existing filling machines with rotating designs for closing elements are structurally complex, expensive, and prone to failure, and their design restricts operational reliability and flexibility, especially during CIP cleaning and disinfection processes.

Innovation Solution

The filling machine employs a lifting cam and inclined plane mechanism to move closing elements between parked and working positions, allowing for a simplified and reliable operation, with a protective wall that adjusts to accommodate the movement and ensure a liquid-tight seal during CIP processes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If independent pneumatic drives are provided at each filling station for moving closing elements, then the closing elements can be moved between parking and working positions, but the structural complexity increases and the device becomes expensive and prone to failure

Engineering Contradiction:
Improvemovement of closing elementsVSAvoidstructural complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

Multiple independent pneumatic drives are merged into a single centralized pneumatic system that controls all closing elements simultaneously. This reduces the number of separate drive units from multiple independent drives to one shared system, simplifying the overall structure while maintaining the ability to move all closing elements between parking and working positions.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The centralized pneumatic system serves multiple functions: it provides lifting motion, swiveling motion, and pressing motion for all closing elements across all filling stations. This multi-functional approach eliminates the need for separate dedicated drives at each station, reducing structural complexity while preserving operational capability.

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

2Adaptability or versatility

If interchangeable components are arranged on the orbit of treatment heads at the same radial distance, then the treatment heads can be adapted to different containers, but a minimum distance between adjacent treatment heads must be maintained which restricts design flexibility

Engineering Contradiction:
Improveadaptation to different containersVSAvoiddesign restrictions
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The support ring is tilted at an angle of 5-15 degrees relative to the horizontal plane, introducing a angular dimension to the arrangement of interchangeable components. This tilting allows components to be positioned at different effective radial distances from the machine axis, enabling closer spacing of treatment heads while maintaining proper clearance and functionality for different container types.

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

AI summary

A filling machine for filling containers includes a rotor, a transport element, a vertical machine axis, and filling positions, each of which comprises a filling element, a container support, and a closure element, and a common actuating drive for all closure elements of the filling machine. The transport element revolves on the rotor about the machine axis. The filling positions are on the transport element. The closure element is a rinsing cap or a rinsing sleeve. Each closure element is movable by the common actuating drive between a parking position and a working position. In the parking position, the closure element is within a movement path of the filling elements. In the working position, the closure element is coaxial with the associated filling element and below the filling element.
