Film Fitting System With Movable Positioning Member
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional film fitting systems face complexity, increased size, and cost due to clamp mechanisms, and low versatility due to fixed positioning recesses, which can lead to interference and inaccurate fitting of tubular films on deviated targets.
Innovation Solution
A film fitting system with a positioning member that moves to a reference position to accurately position the target and retracts to avoid interference, using a moving device with elastic elements and a reference position changing unit to adapt to different target shapes, allowing for simple and accurate fitting operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a clamp mechanism is used to position the fitting target, then positioning accuracy is improved, but device complexity increases
Solution Approach 1:
The patent extracts the positioning function from a complex clamp mechanism and implements it through a simple movable positioning member that can be easily adjusted and repositioned, thereby achieving accurate positioning without the complexity of traditional clamping systems
Solution Approach 2:
The positioning member is designed to be movable rather than fixed, allowing it to be dynamically adjusted to different positions along the mount to accommodate various fitting target shapes and sizes, replacing the need for complex fixed clamp mechanisms
2Manufacturing precision
If a positioning recess (pocket) is provided on the mount, then positioning accuracy is improved, but versatility decreases
Solution Approach 1:
The patent replaces the fixed positioning recess with a movable positioning member that can be adjusted to different positions, transforming a static, shape-specific positioning solution into a dynamic, adaptable system that can handle various fitting target shapes and sizes
Solution Approach 2:
The movable positioning member serves multiple functions: it can be positioned at different locations to accommodate different fitting target shapes, sizes, and orientations, making the mount universally applicable to various types of fitting targets rather than requiring shape-specific recesses
3Manufacturing precision
If a positioning recess is used to position the fitting target, then positioning accuracy is improved, but interference with the fitting device occurs
Solution Approach 1:
The positioning member is designed to be movable and can be retracted or adjusted away from the fitting area during the film fitting operation, eliminating interference between the positioning mechanism and the fitting device while maintaining positioning accuracy when needed

AI summary
A film fitting system which fits a tubular film on a fitting target including a fitting device which fits, at a predefined fitting position, the tubular film on the fitting target which is transported; and a transporting device which receives the fitting target at a predefined supplying position, wherein the transporting device includes a mount which is moved in a state where the fitting target is placed thereon; a positioning member which is moved in a linked manner with the mount and which positions the fitting target with respect to the mount by contacting a part of the fitting target; and a moving device which moves the positioning member to a reference position, and a retracted position where the positioning member is separated from the fitting target at least at the fitting position.
