Solution Overview

Problem

Existing solutions for transferring lap rolls from a lap-forming machine to a transport vehicle are either expensive or complex, particularly when dealing with height differences between the delivery and take-up points, which can vary across different combing machines.

Innovation Solution

A pivotably mounted receptacle with an adjustable boundary wall and sloping guide surface allows for the precise positioning and transfer of lap rolls to transport vehicles with varying receiving heights, ensuring the rolls are not compressed and are guided laterally during pivoting, using gravity and adjustable mounting to maintain the roll's position.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If lifting cylinders and swivel cylinders are used to transfer laps at different heights, then height difference compensation is achieved, but device complexity and cost increase

Engineering Contradiction:
Improveheight difference compensationVSAvoidcomplexity of guides and control elements
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The support frame is made pivotable about a horizontal axis, allowing dynamic adjustment of the delivery height to match different receiving heights on combing machines. This dynamic positioning eliminates the need for complex lifting cylinders and height adjustment mechanisms, resolving the contradiction between adaptability and device complexity.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If the support frame is raised and swiveled to transfer laps, then different receiving heights are accommodated, but the structure becomes more expensive and complex

Engineering Contradiction:
Improveaccommodation of different receiving heightsVSAvoidcost and complexity of the system
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The pivotable support frame provides a simple mechanical solution for accommodating different receiving heights, replacing expensive and complex lifting and positioning systems. The pivot mechanism allows easy adjustment while maintaining manufacturing simplicity.

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If multiple transport carriages with different receiving heights are used, then adaptability to various combing machines is achieved, but device complexity increases

Engineering Contradiction:
Improvecompatibility with various combing machinesVSAvoidnumber of transport carriages required
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Instead of using multiple static transport carriages with different fixed receiving heights, the invention employs a single pivotable support frame that can dynamically adjust its delivery height. This eliminates the need for multiple specialized carriages, reducing device complexity while maintaining full adaptability to various combing machines.

Inventive Principle:
Principle #15Dynamics
