Cantilevered Roller Cage Layout for Compact Profiling Lines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current roller cages for profiling lines require extensive space, double the equipment for quick changeovers, pose handling risks due to heavy weight, and suffer from inefficiencies in power transmission, leading to increased costs and energy losses.
Innovation Solution
A compact roller cage design featuring cantilevered shaped rollers directly mounted on spindles, eliminating the need for reduction gearboxes and transmission members, with adjustable motors and frames for easy maintenance and alignment, allowing for reduced space usage and improved accessibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If traditional roller cages with reduction gearboxes and transmission members are used, then power transmission is achieved, but space requirements increase and energy losses occur
Solution Approach 1:
The patent removes the reduction gearbox and transmission members from the roller cage system. The shaped rollers are mounted directly on spindles that protrude from the support frame, eliminating the intermediate transmission components that cause energy losses and occupy space.
Solution Approach 2:
The patent positions the motors directly adjacent to the spindles, creating a direct drive configuration where the power source is at the same location as the driven element, eliminating energy losses in transmission and reducing the number of moving parts.
2Productivity
If double sets of replacement plates are maintained for quick changeovers, then production continuity is improved, but equipment costs increase
Solution Approach 1:
The patent designs the roller cage as a modular unit that can be quickly removed and replaced as a complete assembly. The support frame, spindles, and shaped rollers form an integrated module that can be swapped without requiring multiple complete sets of replacement plates.
Solution Approach 2:
The patent enables dynamic reconfiguration of the roller cage by allowing the shaped rollers to be independently adjusted and replaced on the support frame, providing flexibility for quick changeovers without requiring duplicate complete sets.
3Ease of operation
If ample spaces are provided for positioning cages outside the line, then equipment changeover is facilitated, but factory floor space increases
Solution Approach 1:
The patent divides the roller cage into a removable module consisting of the support frame and shaped rollers that can be easily transported and repositioned in limited space, reducing the need for large storage areas outside the production line.
4Ease of repair
If heavy roller cages are handled with overhead travelling cranes, then equipment replacement is possible, but safety risks increase
Solution Approach 1:
The patent designs the roller cage as a modular assembly with the support frame and shaped rollers that can be handled as a smaller, lighter unit compared to traditional integrated designs, reducing the weight and risks associated with crane handling.

AI summary
A roller cage for a profiling line, comprising: a support frame (F1) that entirely delimits a non-operating area (A1) which is external to the line; at least a motor (11) provided with a spindle (12) protruding externally of the non-operating area (A1); at least a shaped roller (13, mounted directly on the spindle (12) and arranged inside an operating area (B) of the line.
