Mandrel Shaping Device for Polygonal Box Forming
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for shaping sheet material around a mandrel to form boxes or box parts with polygonal sections require numerous independent devices that need precise adjustment, resulting in complexity and bulkiness.
Innovation Solution
A device with a frame and two nacelles on either side of the mandrel, supporting means for rolling up and fixing flaps and a tongue, allowing translational and rotational movements for precise shaping without the need for multiple independent adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If numerous independent devices are used for shaping the blank around the mandrel, then the shaping precision can be maintained, but the device complexity and bulkiness increase significantly
Solution Approach 1:
The patent combines multiple independent shaping devices into a single integrated device that performs rolling up, folding, and fixing operations simultaneously. The device includes a rolling-up means, a folding means, and a fixing means all integrated into one unit that processes the blank in a coordinated manner, thereby reducing device complexity while maintaining shaping precision through unified control of all operations
Solution Approach 2:
The integrated device performs multiple functions including rolling up the blank around the mandrel, folding the flaps, and fixing the shaped blank in one operation. This multi-functional approach eliminates the need for separate independent devices for each operation, reducing overall device complexity while maintaining the precision required for each individual shaping step
2Manufacturing precision
If numerous independent devices are used for shaping the blank around the mandrel, then the shaping operations can be performed, but the device bulkiness increases significantly
Solution Approach 1:
The patent merges multiple independent shaping devices into one compact integrated unit. The rolling-up means, folding means, and fixing means are combined into a single device structure that occupies less space than multiple separate devices would require, thereby reducing device bulkiness while maintaining full shaping capability
Solution Approach 2:
The integrated device structure allows components to be nested or arranged in a compact configuration where the rolling-up means, folding means, and fixing means are positioned to utilize the same spatial envelope, reducing the overall volume occupied by the device while maintaining all necessary shaping functions

AI summary
The present invention relates to a device for shaping a blank (1) of material in sheet form around a mandrel, in order to obtain a box or part of box of polygonal cross section, comprising: – a mandrel, – means for wrapping around the mandrel, – means for securing the tab, – means for folding the flaps, and – means for fixing together the flaps thus folded. The means for wrapping the panels and the means for securing the tab are supported by two cradles positioned one on each side of the mandrel, transversely and symmetrically with respect to the direction in which the blank is brought in from the glue-application workstation.
