Solution Overview

Problem

Conventional conveyor systems for handling inert materials in the railway sector are bulky, heavy, and require high-power motors, leading to increased costs and complex maintenance procedures, with inefficient roller movement and frequent downtime due to locking issues and high friction.

Innovation Solution

A conveyor system with a compact structure featuring a support frame, rollers, and an interconnection system that synchronizes the rotation of multiple rollers to efficiently move the belt, reducing the need for high-power motors and simplifying maintenance by allowing individual component replacement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If bars are fixed along the entire perimeter development of the belt to support the belt during load handling, then the belt is properly supported, but the conveyor structure becomes excessively voluminous and heavy

Engineering Contradiction:
Improvebelt supportVSAvoidconveyor structure weight
Core Design Contradiction:
ReliabilityVSWeight of stationary object

Solution Approach 1:

The continuous bar structure is segmented into discrete support bars that are selectively positioned only at critical support points along the belt perimeter. This segmentation reduces the total volume and weight of the support structure while maintaining adequate belt support during load handling operations.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Instead of uniform bar distribution along the entire belt perimeter, support bars are strategically placed only at locations where local support is needed. This local quality approach concentrates support elements where they provide maximum benefit while minimizing overall structure weight and volume.

Inventive Principle:
Principle #3Local quality

2Reliability

If bars are fixed along the entire perimeter development of the belt, then the belt is properly supported, but the overall dimensions of the conveyor become excessively large

Engineering Contradiction:
Improvebelt supportVSAvoidconveyor structure volume
Core Design Contradiction:
ReliabilityVSVolume of moving object

Solution Approach 1:

The continuous bar structure is segmented into discrete support bars that are selectively positioned only at critical support points along the belt perimeter. This segmentation reduces the total volume and weight of the support structure while maintaining adequate belt support during load handling operations.

3Power

If high-power motors are installed to drive the heavy conveyor structure, then the conveyor can move the belt, but the production and operating costs increase

Engineering Contradiction:
Improvemotor powerVSAvoidproduction and operating costs
Core Design Contradiction:
PowerVSEase of manufacture

Solution Approach 1:

The continuous bar structure is segmented into discrete support bars that are selectively positioned only at critical support points along the belt perimeter. This segmentation reduces the total volume and weight of the support structure while maintaining adequate belt support during load handling operations.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

4Ease of repair

If the entire chain and each individual bar are removed for maintenance or repair, then the bars can be replaced, but the intervention time and downtime increase considerably

Engineering Contradiction:
Improvebar replacementVSAvoidmaintenance downtime
Core Design Contradiction:
Ease of repairVSLoss of time

Solution Approach 1:

The continuous bar structure is segmented into discrete support bars that are selectively positioned only at critical support points along the belt perimeter. This segmentation reduces the total volume and weight of the support structure while maintaining adequate belt support during load handling operations.

Inventive Principle:
Principle #1Segmentation

5Ease of operation

If bearings are used to hinge the bars to the chain, then the bars can move smoothly, but the bearings are subjected to locking due to working conditions

Engineering Contradiction:
Improvebar movementVSAvoidbearing reliability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The continuous bar structure is segmented into discrete support bars that are selectively positioned only at critical support points along the belt perimeter. This segmentation reduces the total volume and weight of the support structure while maintaining adequate belt support during load handling operations.

AI summary

The present invention relates to a railway wagon comprising a base structure (201) having a support platform (202) and two carriages (203) configured to support the support platform (202) and allow movement of the base structure (201) along rails. The carriage also comprises a conveyor (100) comprising: a support frame (1), a plurality of rollers (10) movable by rotation around a rotation axis (A) thereof and aligned along a predetermined trajectory transverse to the rotation axes (A). The multiplicity of rollers (10) comprises: a first end return roller (11'), a second end return roller (11") spaced from the first end return roller (11'), a predetermined number of intermediate rollers (12) interposed between said first and second end return rollers (11', 11"). The conveyor further comprises a belt (20) wound around the rollers and a motor (30) active on at least a roller (10) to define a motorized roller (13). The conveyor (100) comprises an interconnection system (40) configured to connect the motorized roller (13) with at least a further roller (10) to define a driven roller (14).
