Hygiene Article Absorber Core Transport via Porous Screen Belt
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The production of hygiene articles, such as sanitary napkins and diapers, faces challenges in maintaining a contamination-free and efficient process flow due to loose particles and material residues from the absorber core mixture, which can interfere with subsequent processing steps and affect product quality.
Innovation Solution
The method involves suspending absorber cores after shaping and portioning, allowing them to be transported 'hanging' with a vacuum-loaded suction belt, supported by a moving sieve belt with appropriate mesh size, to separate and remove loose particles using gravity, ensuring reliable removal before embedding in material webs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the material stream is transported conventionally on a solid belt, then the transport is stable and reliable, but loose particles and material residues cannot be effectively removed
Solution Approach 1:
The patent employs a porous or perforated belt structure that allows loose particles and material residues to fall through the belt during transport. The belt contains openings of specific size (0.5-5mm) that enable gravity-driven removal of contaminants while maintaining structural integrity for reliable transport of the absorber core material stream.
Solution Approach 2:
The invention extracts harmful loose particles and material residues from the material stream by allowing them to fall through the porous belt during transport. This separation process removes contaminants before the material reaches subsequent processing stages, preventing disruptions and quality issues.
2Productivity
If the production process runs at high throughput rates, then productivity increases, but contamination and disruptions from loose particles increase
Solution Approach 1:
The porous belt transport system performs preliminary removal of loose particles and contaminants before the material enters subsequent processing stages. This preventive action ensures that high throughput rates do not lead to accumulation of contaminants that could cause disruptions or quality problems later in the process.
3Reliability
If a porous belt is used for transport, then loose particles can be removed by gravity, but the belt structure becomes more complex
Solution Approach 1:
The patent implements a porous or perforated belt with openings of 0.5-5mm that enables gravity-driven removal of loose particles during transport. Despite the increased structural complexity compared to solid belts, the design maintains simplicity through regular geometric patterns and standard manufacturing techniques, achieving reliable particle removal without excessive complexity.
