Solution Overview

Problem

Existing conveyor systems for orienting and grouping flat baking products are inefficient, requiring expensive and inflexible industrial robots, which complicate line changes and increase footprint, and struggle to adapt to different packaging types and speeds.

Innovation Solution

A conveyor assembly with a first conveying device for forming partial stacks and a second conveying device driven by a linear motor, using individually controlled carrier members and a forming plate with grooves to adjust orientation and positioning, allowing for quick and reliable adaptation to various packaging configurations without the need for complex robot reconfiguration.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If industrial robots are used to orient and group flat baking products, then the products can be oriented and grouped correctly, but the device complexity and cost increase significantly

Engineering Contradiction:
Improveorientation and grouping accuracyVSAvoidrobot system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system divides the orientation and grouping process into two separate stages: first, a simple conveying device forms partial stacks of products; second, a forming plate with grooves completes the grouping and orientation. This segmentation eliminates the need for complex industrial robots while achieving the same functional result through divided, simpler operations.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The forming plate with grooves acts as an intermediary device between the partial stacks and the final packaged product. The grooves guide and orient the partial stacks into the correct configuration without requiring complex robotic manipulation, thereby simplifying the overall system while maintaining reliability.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Extent of automation

If industrial robots are used for orientation and grouping, then product handling is automated, but the footprint and floor area usage increase

Engineering Contradiction:
Improveproduct handling automationVSAvoidfloor area usage
Core Design Contradiction:
Extent of automationVSArea of stationary object

Solution Approach 1:

The first conveying device and the forming plate are merged into a compact integrated system that performs both partial stacking and final grouping in close proximity. This merging eliminates the need for large robotic workspaces while maintaining full automation of the orientation and grouping process.

Inventive Principle:
Principle #5Merging (Combining)

3Extent of automation

If industrial robots are used for orientation and grouping, then production flexibility is reduced, but automation level is high

Engineering Contradiction:
Improveautomation levelVSAvoidproduction line adaptability
Core Design Contradiction:
Extent of automationVSAdaptability or versatility

Solution Approach 1:

The system uses adjustable and reconfigurable components, including the forming plate with adjustable grooves and the first conveying device with variable parameters. This dynamic design allows quick adaptation to different product types, packaging requirements, and production volumes without complex robotic reprogramming, maintaining high automation while improving versatility.

Inventive Principle:
Principle #15Dynamics

4Reliability

If complex robot systems are used, then orientation and grouping can be achieved, but line changeover becomes complicated and time-consuming

Engineering Contradiction:
Improveorientation and grouping accuracyVSAvoidline changeover time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The first conveying device pre-forms partial stacks with correct initial orientation before the products reach the forming plate. This preliminary action reduces the complexity of the final grouping step and enables rapid changeover when product specifications change, as the pre-stacking mechanism can be quickly adjusted without affecting the entire system.

Inventive Principle:
Principle #10Preliminary action
