Solution Overview

Problem

Existing automatic spooling systems struggle with processing spools with irregular shapes and orientations, leading to reduced productivity as they cannot handle spools with anomalous geometries efficiently, resulting in decreased overall efficiency and increased downtime.

Innovation Solution

A device and process that utilize an optical sensor to detect the profile of spools in motion, orient them correctly, and divert irregular spools for separate handling, ensuring only properly shaped spools are fed to the spooling stations, using a controlling unit to manage the sorting and orientation process.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If automatic spooling systems process spools with irregular shapes and orientations, then productivity increases, but system complexity increases

Engineering Contradiction:
Improvespool processing capacityVSAvoidspool control system complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The system performs preliminary detection and classification of spools before they enter the main processing line. Optical sensors detect spool shape and orientation characteristics in advance, and the controlling unit pre-determines the appropriate handling path, thereby avoiding complex real-time processing adjustments and maintaining system simplicity while increasing productivity

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent introduces an intermediary control system consisting of optical sensors and a controlling unit that mediates between the bulk spool input and the automated spooling stations. This intermediary layer classifies and orients spools beforehand, allowing the main processing system to operate with simpler, more standardized mechanisms while handling irregular spools through the intermediary's sorting and orientation functions

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If spools are handled individually to maintain upright position, then spool integrity is preserved, but handling time increases

Engineering Contradiction:
Improvespool position stabilityVSAvoidspool handling time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system preliminarily orients spools in the correct upright position before they reach the automated spooling stations through the controlling unit's coordination of transport mechanisms. This pre-positioning action ensures spool integrity is maintained without requiring complex individual handling at each station, thereby reducing overall handling time while preserving reliability

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent implements continuous transport and orientation of spools through an integrated system where the controlling unit coordinates multiple transport elements. Instead of intermittent individual handling, spools undergo continuous movement through oriented transport paths, maintaining upright position throughout the process while minimizing idle time and maximizing handling efficiency

Inventive Principle:
Principle #20Continuity of useful action

3Productivity

If all spools are processed through the same path, then device simplicity is maintained, but processing efficiency decreases

Engineering Contradiction:
Improvespool processing efficiencyVSAvoidspool routing complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent segments the spool processing path into distinct routes based on spool characteristics. The controlling unit divides the workflow into separate paths for different spool types (regular vs. irregular shapes, different orientations), allowing each segment to be optimized for its specific requirements. This segmentation increases productivity by matching the right processing method to each spool while keeping individual route complexity manageable

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system dynamically adjusts the processing path based on real-time detection of spool characteristics. The controlling unit receives input from optical sensors and dynamically routes spools to appropriate processing stations, creating a flexible system that adapts to varying spool geometries. This dynamic routing increases efficiency by optimizing the path for each spool while managing overall system complexity through automated decision-making

Inventive Principle:
Principle #15Dynamics

AI summary

Device and process for controlling spools coming in bulk from spinning and for subsequently feeding them for automatic spooling, wherein spools (2) travel on a main conveyor belt (1) whereon an optical sensor (3) is arranged, wherein the spool (2) in motion with the belt (1), thus acquiring the profile and the posture of the spool (2). On the basis of the detected profile, a deviating element (5) deviates the normal spools on a secondary sorting line (6) that receives and works the deviated spools towards the spooler and to be oriented with the base downwards, or does not deviate the anomalous spools from the main conveyor belt (1), letting them continue towards a collecting box for their subsequent separate treatment.
