Capping Head Recess for Cone Cam Nesting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing capping heads with multiple forming rollers face challenges in maintaining a compact size and weight, leading to reduced processing speed and efficiency due to increased dimensions and weight.
Innovation Solution
A capping head design with a body recess portion accommodating the cone cam, allowing closer placement of forming rollers and cone cam, along with a spindle attachment portion and biasing members, uses a lightweight aluminum alloy and optimized roller configurations to reduce weight and increase processing speed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a large number of forming rollers are provided, then the forming load per forming roller is reduced and deformation of the mouthpiece portion is suppressed, but the outer shape dimension and weight of the capping head are increased
Solution Approach 1:
The cone cam is nested within the body recess portion, allowing the forming rollers to be positioned closer together without increasing the overall outer dimensions of the capping head. This nesting arrangement enables multiple forming rollers to be accommodated within a compact structure, maintaining forming accuracy while controlling weight and size.
Solution Approach 2:
The body recess portion creates a three-dimensional arrangement where the cone cam and forming rollers are positioned in a radially inward direction from the outer periphery. This dimensional reorganization allows for a more compact layout that reduces the capping head's outer shape dimensions while accommodating the necessary forming rollers.
2Reliability
If a large number of forming rollers are provided, then the forming load per forming roller is reduced, but the processing speed of the capping is reduced
Solution Approach 1:
By nesting the cone cam within the body recess portion, the forming rollers can be arranged in a compact configuration that reduces the overall size of the capping head. This compact arrangement minimizes the moment of inertia and allows for faster acceleration and deceleration of the forming rollers, thereby increasing the processing speed while maintaining the benefits of multiple rollers for forming accuracy.
Solution Approach 2:
The radial arrangement of forming rollers within the body recess portion creates a more compact structure with reduced outer dimensions. This dimensional optimization allows the capping head to achieve higher processing speeds by reducing the mechanical inertia associated with larger structures, while still providing multiple forming rollers for accurate cap formation.
3Force
If the number of forming rollers is increased, then the forming load is distributed better, but the weight of the capping head increases
Solution Approach 1:
The cone cam is positioned within the body recess portion, allowing multiple forming rollers to be arranged in a radially distributed pattern that optimizes force distribution. This nested configuration enables the forming rollers to be closer to the center axis, reducing the lever arm and thereby reducing the weight required for the same forming load capacity.
Solution Approach 2:
The forming rollers are arranged in a radial dimension within the body recess portion, creating a compact structure that distributes forming loads more effectively. This radial arrangement allows for better force distribution across multiple rollers while minimizing the overall weight by reducing the outer dimensions of the capping head.
