Solution Overview

Problem

Spiral conveyors face challenges in arranging non-rotating functional elements and feeding supply lines within the enclosed space, and containers are uncontrolledly raised and lowered during transport, requiring significant design effort and resulting in inefficient cleaning processes.

Innovation Solution

A spiral conveyor design featuring a helical transport path around a vertical machine axis with sliding guides and guide rails, supported by a slewing ring and driven by a machine drive, allowing for the arrangement of nozzles and supply lines without rotary distributors, enabling controlled container movement and efficient cleaning.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If a horizontal machine axis is used for the helical transport path, then the spiral conveyor can be compact, but containers are uncontrolledly raised and lowered multiple times during transport, requiring significant design effort and resulting in inefficient cleaning processes

Engineering Contradiction:
Improvespatial requirementsVSAvoidcontainer movement control
Core Design Contradiction:
Volume of moving objectVSEase of operation

Solution Approach 1:

The patent inverts the conventional horizontal machine axis configuration by using a vertical machine axis instead. This inversion fundamentally changes the transport dynamics: containers move in a single continuous upward direction along the helical path rather than being repeatedly raised and lowered, thereby eliminating the need for complex control mechanisms while maintaining compact spatial requirements.

Inventive Principle:
Principle #13The other way round (Inversion)

2Adaptability or versatility

If non-rotating functional elements and supply lines are arranged within the enclosed space of the spiral conveyor, then functional integration is achieved, but design effort and complexity increase significantly

Engineering Contradiction:
Improvefunctional integrationVSAvoiddesign effort
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

By inverting the machine axis to vertical orientation, the patent creates a stable central core around which non-rotating functional elements can be arranged. This vertical axis configuration allows supply lines and functional components to be fed into the enclosed space from the top or bottom without requiring rotary distributors or rotary joints, thereby achieving functional integration while avoiding the complexity associated with rotating connections.

Inventive Principle:
Principle #13The other way round (Inversion)

3Device complexity

If containers are transported on a helical path around a horizontal axis, then the conveyor structure is simplified, but cleaning efficiency decreases due to uncontrolled container movement

Engineering Contradiction:
Improveconveyor structureVSAvoidcleaning efficiency
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The patent achieves both structural simplicity and cleaning efficiency by inverting the machine axis to vertical orientation. The helical transport path around a vertical axis provides inherent stability to containers during transport, enabling controlled movement that allows cleaning nozzles to effectively treat containers. This configuration maintains a simple conveyor structure while simultaneously improving cleaning efficiency through stable, controlled container positioning.

Inventive Principle:
Principle #13The other way round (Inversion)

AI summary

Spiral conveyor for containers (2) with at least one transport section (3) enclosing a machine axis (MA) in a spiral shape, which is defined by container guide and/or sliding elements (6, 8) located outside the machine axis (MA) and by container guide and/or sliding elements (7, 9) located inside the machine axis (MA) and extends between a container inlet (4) and a container outlet (5), and with at least one driver (14) which extends over the entire length of the spiral formed by the transport section (3) and penetrates the transport section or its spiral in the area between the outer container guide and/or sliding elements (6, 8) and the inner container guide and/or sliding elements (7, 9) and is held on at least two driver support elements (15, 16) that can be driven around the machine axis (MA).
