Foil Reel Mounting Device with Retaining Element
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge in the packaging industry is the safe and efficient handling of heavy and costly stamping foil reels, which are prone to damage during mounting due to their weight, especially when they can weigh up to 300 kg, posing economic and operational risks.
Innovation Solution
A foil reel mounting device with a retaining element that biases towards a closed position to securely hold the reel in place, featuring a cam surface for easy access and an electromagnetic brake for tension control, along with a handling tool for external lifting, ensures safe and efficient loading and unloading of reels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If manual handling of heavy reels is used, then installation simplicity is maintained, but damage risk increases due to weight up to 300 kg
Solution Approach 1:
The patent introduces a forklift truck as an intermediary lifting device to handle the heavy reel. The forklift inserts forks under the reel and lifts it to the mounting position, eliminating direct manual handling while maintaining simple installation procedures. This mediator resolves the contradiction by providing mechanical assistance for heavy loads without complicating the overall installation process.
2Ease of operation
If the retaining element is held open for easy loading, then ease of operation improves, but reliability decreases due to potential accidental operation
Solution Approach 1:
The patent employs a locking mechanism that automatically locks the retaining element in the closed position after loading. The spring-loaded retaining element naturally tends to close and lock, requiring deliberate action to open. This preliminary anti-action (automatic locking) prevents accidental operation while maintaining ease of loading through the simple release mechanism.
3Reliability
If the retaining element is spring-loaded to stay closed, then reliability improves by preventing accidental operation, but ease of operation worsens due to additional locking mechanisms
Solution Approach 1:
The patent segments the retaining element into functional parts: a spring-loaded body for automatic closing and locking, and a separate release mechanism for opening. This segmentation allows the retaining element to maintain reliability through automatic locking while preserving ease of operation through the dedicated, simple release action. The complexity is distributed and managed through clear functional separation.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides a secure and efficient method for handling and mounting stamping foil reels, preventing damage and ensuring smooth operation by maintaining reel position during use and allowing for controlled tension, thus reducing operational risks and costs.
Implementation Method 1
The retaining element has a cam surface configured to cooperate with the axle of the reel to displace the retaining element from the closed position to the open position
Implementation Method 2
featuring a cam surface for easy access and an electromagnetic brake for tension control

AI summary
A foil reel mounting device for supporting a reel of stamping foil in a supporting module. The device includes a support having a recess to receive an axle of the reel of stamping foil. A retaining element mounted on the support and arranged to move between a closed position, in which the retaining element retains the axle of the reel in the recess, and an open position, in which the retaining element releases the axle of the reel from the recess. The retaining element is biased towards the closed position. Also, a supporting module has at least one foil reel mounting device and a stamping machine includes a supporting module or at least one foil reel mounting device. A method for loading and unloading a reel of stamping foil with such at least one foil reel mounting device is also disclosed.
