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

VSEngineering 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

Engineering Contradiction:
Improvepower lossesVSAvoidtransmission system
Core Design Contradiction:
Loss of energyVSDevice complexity

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.

Inventive Principle:
Principle #2Taking out (Extraction)

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.

Inventive Principle:
Principle #12Equipotentiality

2Productivity

If double sets of replacement plates are maintained for quick changeovers, then production continuity is improved, but equipment costs increase

Engineering Contradiction:
Improveproduction continuityVSAvoidequipment quantity
Core Design Contradiction:
ProductivityVSQuantity of substance

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.

Inventive Principle:
Principle #1Segmentation

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.

Inventive Principle:
Principle #15Dynamics

3Ease of operation

If ample spaces are provided for positioning cages outside the line, then equipment changeover is facilitated, but factory floor space increases

Engineering Contradiction:
Improveequipment changeoverVSAvoidfactory floor space
Core Design Contradiction:
Ease of operationVSArea of stationary object

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.

Inventive Principle:
Principle #1Segmentation

4Ease of repair

If heavy roller cages are handled with overhead travelling cranes, then equipment replacement is possible, but safety risks increase

Engineering Contradiction:
Improveequipment replacementVSAvoidhandling risks
Core Design Contradiction:
Ease of repairVSObject-affected harmful factors

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.

Inventive Principle:
Principle #1Segmentation

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.
