Coil Sampling Stand With Bottom Peeler Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coil sampling methods pose safety risks and inefficiencies due to exposed moving parts and uncontrolled uncoiling forces, particularly for coils with specific thickness gauges and diameters, which can cause the coil to rock or roll off the sampling stand.
Innovation Solution
A coil sampling apparatus with a frame, rollers, and a peeler assembly where the peeler is positioned between the rollers to safely peel the coil from the bottom, reducing exposure to moving parts and uncoiling forces, and featuring adjustable components to accommodate various coil sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the peeler is positioned to peel the coil from the side or top, then the peeling action is straightforward, but the moving parts are exposed and safety risks increase
Solution Approach 1:
The peeler is repositioned to peel the coil from the bottom instead of the side or top, inverting the conventional peeling direction. This allows the peeler to operate between the rollers with the coil passing over it, hiding the moving peeler under the frame and eliminating exposure hazards while maintaining effective peeling action
2Device complexity
If the coil is unwound without support rollers, then the uncoiling process is simple, but the coil may rock or roll off the stand due to uncoiling forces
Solution Approach 1:
A support roller is introduced as an intermediary element between the coil and the frame. This roller provides continuous support to the coil during unwinding, preventing the coil from rocking or rolling off the stand while the peeler removes the outer layer, thereby ensuring stable and reliable operation
3Device complexity
If the sampling stand is designed for fixed coil sizes, then the structure is simpler, but it cannot accommodate various coil sizes efficiently
Solution Approach 1:
The support roller and peeler assembly are made adjustable rather than fixed. The support roller can be repositioned along the frame to accommodate different coil diameters, and the peeler height can be adjusted to match various coil thicknesses, enabling the stand to handle a range of coil sizes without structural modification

AI summary
Aspects of the present invention relate to a coil sampling stand apparatus which generally has a frame, at least two rollers operatively coupled to the frame, a roller drive operatively coupled to at least one of the at least two rollers, and a peeler assembly comprising a peeler (e.g., peeler, knife, member with an edge, or the like) that is configured to engage and disengage a coil between the at least two rollers. The steel coil may be positioned onto the at least two rollers on the frame of the coil sampling apparatus. The peeler is engaged with the coil and the coil is rotated in order to allow the peeler to peel a tail edge of a layer of the coil off the coil and pass the tail edge and layer of the coil peeled off of the coil under at least one of the rollers.
