Solution Overview

Problem

Conventional creel robots face challenges in collecting yarn-unwound paper tubes while preventing damage to the caps, requiring manual intervention and increasing operational burdens.

Innovation Solution

A creel robot equipped with an accommodation unit, extraction unit, and a separator device that separates the cap from the yarn-unwound cylindrical member, allowing for safe collection without operator intervention, utilizing magnetic attraction and vibration to facilitate cap separation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If the creel robot drops the extracted yarn-unwound paper tube on the paper-tube-receiving base to collect it, then the collection process is automated, but the cap fitted to the yarn-unwound paper tube may be damaged

Engineering Contradiction:

Improveautomation of paper tube collectionVSAvoidcap damage

Core Design Contradiction:

Extent of automationVSObject-affected harmful factors

Solution Approach 1:

The invention separates the collection process into two distinct stages: first collecting the yarn-unwound paper tubes with caps intact, then separately removing and collecting the caps. This segmentation allows the paper tubes to be collected gently without cap damage, while the caps are handled separately after removal, resolving the contradiction between automation and cap protection.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The invention performs preliminary removal of caps from yarn-unwound paper tubes before dropping them into the receiving base. By removing the caps in advance, the paper tubes can be collected without the risk of cap damage during the dropping process, while the removed caps are collected separately, thus achieving both automation and cap protection.

Inventive Principle:

Principle #10Preliminary action

2Object-affected harmful factors

If an operator manually collects the cap from the creel stand, then the cap is protected from damage, but the operator bears a large burden and manual intervention is required

Engineering Contradiction:

Improvecap damage preventionVSAvoidoperator burden

Core Design Contradiction:

Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The invention enables the system to serve itself by automatically removing caps from yarn-unwound paper tubes and collecting both the tubes and caps separately through automated mechanisms. This eliminates the need for operator intervention in cap collection, reducing operator burden while ensuring caps are handled carefully to prevent damage.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The invention replaces manual operator actions with automated mechanical systems. The cap removal and collection processes that previously required manual operator intervention are now performed by automated mechanisms, reducing operator burden while maintaining cap protection through controlled mechanical handling.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Productivity

If the cap is reused by detaching it from the yarn-unwound paper tube and attaching it to another new yarn feeding package, then resource efficiency is improved, but the cap may be damaged during the process

Engineering Contradiction:

Improvecap reuse efficiencyVSAvoidcap damage

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The invention implements a systematic process where caps are recovered from yarn-unwound paper tubes in a controlled manner, separated for inspection and maintenance, and then reused on new yarn feeding packages. This structured recovery and reuse process ensures caps are handled carefully to prevent damage while maintaining high reuse efficiency and resource productivity.

Inventive Principle:

Principle #34Discarding and recovering

AI summary

[Problem to be Solved] To provide a creel robot capable of achieving man-power savings while preventing a cap from being damaged and a system including the same. [Solution to Problem] A yarn feeding package has a yarn-unwound paper tube 100 fitted with a cap 110 at an end thereof. The yarn-unwound paper tube 100 fitted with the cap 110 obtained after a yarn has been thoroughly unwound from the yarn feeding package is extracted from a peg shaft 36 of a creel stand 30 to be accommodated in a yarn-unwound paper tube accommodation box 84. The yarn-unwound paper tube 100 accommodated in the yarn-unwound paper tube accommodation box 84 is separated from the cap 110. The yarn-unwound paper tube 100 having been separated from the cap 100 is collected in a yarn-unwound paper tube collection box.
