Suction Transfer Device for Bag-Like Articles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional suction devices struggle to transfer bag-like articles without causing deformation, leading to potential drops during transfer due to gaps formed between the articles and the seal members.
Innovation Solution
A suction transfer device with a suction component featuring a negative pressure chamber, suction openings, and a first surface with a large area relative to the article, ensuring firm support and reduced likelihood of drops, along with adjustable features like a second surface angle and air discharge for quick release.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a narrow annular seal member is used for suction-holding, then the suction device structure is simple, but the bag-like article becomes deformed during transfer and gaps form between the article and seal member
Solution Approach 1:
The suction component is divided into multiple functional regions: a first surface for supporting the article, suction openings for creating negative pressure, and a second surface for rapid release. This segmentation allows each region to perform its specific function optimally, preventing deformation while maintaining simple structure.
Solution Approach 2:
The invention transitions from a traditional annular seal member (one-dimensional ring structure) to a multi-dimensional suction component with surfaces, openings, and chambers. This dimensional expansion enables simultaneous support and suction functions, improving reliability without significantly increasing complexity.
2Reliability
If a large area first surface is used to support the article, then article deformation is reduced, but the suction component size increases
Solution Approach 1:
The suction component applies different properties to different regions: the first surface provides a large area for support stability, while the suction openings concentrate negative pressure force locally. This local differentiation allows the component to achieve both support stability and compact size.
3Force
If suction openings with sufficient area are provided, then article suction-holding force is improved, but the first surface area for support is reduced
Solution Approach 1:
The suction openings are designed with sufficient area to generate strong suction force, while the first surface extends beyond the suction openings to provide additional support area. This partial action approach ensures that the suction openings provide adequate holding force without requiring the entire component surface to be dedicated to suction.
4Reliability
If negative pressure is applied strongly to prevent drops, then article holding is secure, but quick release becomes difficult
Solution Approach 1:
The invention separates the suction-holding function and the release function into distinct structural elements: the suction openings and negative pressure chamber for holding, and the second surface for rapid release. This extraction allows independent optimization of both holding security and release speed without compromise.
Solution Approach 2:
The suction component operates in periodic cycles: negative pressure is applied for secure holding during transfer, then the second surface enables rapid release when needed. This periodic switching between strong holding and quick release states optimizes both reliability and ease of operation.

AI summary
A suction transfer device suction-holds a bag-like article with a suction component and moves the suction component suction-holding the article to thereby transfer the article. The suction component has a negative pressure chamber, one or more suction openings, and a first surface. The negative pressure chamber forms a negative pressure space inside when a negative pressure generator is driven. The suction openings communicate with the negative pressure chamber. The first surface is disposed around the suction openings and opposes an article subjected to suction. An area of the first surface is from 0.5 times to 2 times an area of a sucked surface, which opposes the first surface, of the article subjected to suction.
