Segmented Mandrel Packaging for Special-Shape Box Forming
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The wrap-around packaging process struggles to form boxes with special shapes, such as those with reduced cross-sections or beveled edges, due to the limitations of traditional mandrels, which often deform or tear the box during extraction.
Innovation Solution
A mandrel composed of separate units that can be assembled and disassembled, allowing for the formation of boxes with special shapes by accommodating and supporting the article and abutting the blank, then decomposing into units for easy extraction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a traditional mandrel is used to form boxes with special shapes (reduced cross-sections or beveled edges), then the box formation process can be completed, but the mandrel deforms or tears the box during extraction
Solution Approach 1:
The mandrel is divided into multiple separable components (first component, second component, etc.) that can be assembled to form the complete mandrel structure. During extraction, these components can be separated or disassembled to avoid interference with the box, particularly for boxes with reduced cross-sections or beveled edges, thereby preventing deformation or tearing of the box.
2Ease of manufacture
If a mandrel is used to form boxes, then the box can be formed around the article, but the mandrel interferes with the box during extraction when the box has special shapes
Solution Approach 1:
The mandrel is designed with movable or adjustable components that can change their configuration. During the box formation process, the mandrel components are positioned to provide proper support and shaping. During extraction, the components can be moved, adjusted, or separated to clear the box path, enabling successful extraction of boxes with special shapes without interference.
3Device complexity
If traditional packaging methods are used, then the packaging process is simple, but flexibility in producing varied box shapes is limited
Solution Approach 1:
The mandrel is constructed from multiple separate components that can be independently positioned, adjusted, or configured. This segmentation allows the same basic packaging device to produce various box shapes (including reduced cross-sections and beveled edges) by reconfiguring the mandrel components, thereby increasing versatility without requiring completely different packaging systems for each box type.

AI summary
A method for packaging articles in boxes includes composing a mandrel from separate units, depositing at least one article inside the mandrel, wrapping a blank around the mandrel to form a box that is at least partially closed around the article deposited in the mandrel, decomposing the mandrel in the plurality of separate units, and leaving the article inside the box. The disclosure also includes a packaging device configured to operate according to such a method.
