Solution Overview

Problem

Modern textile machines face challenges in efficiently storing and transporting different types of tubes to workstations on long machines, leading to increased waiting times and limited capacity for supplying winding units with various tubes.

Innovation Solution

A spinning machine design with multiple cross-winding devices arranged in sections, featuring distributed sleeve storage along the machine sides, where each section has its own tube magazine and a tube transport device, allowing for quick access and transport of different types of tubes to the required workstations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a single central magazine is used for storing empty bobbins, then the structure is simple, but the capacity for supplying different types of bobbins is severely limited

Engineering Contradiction:
Improvestructure simplicityVSAvoidcapacity for supplying different types of bobbins
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The single central magazine is divided into multiple sectionally arranged magazines, each dedicated to storing specific types of bobbins. This segmentation allows the system to maintain structural simplicity at the overall level while achieving high adaptability through localized specialization, enabling supply of multiple different bobbin types to various winding points

Inventive Principle:
Principle #1Segmentation

2Device complexity

If bobbins are transported the entire machine length, then a single transport path is used, but the transport time increases considerably

Engineering Contradiction:
Improvetransport path simplicityVSAvoidbobbin transport time
Core Design Contradiction:
Device complexityVSLoss of time

Solution Approach 1:

The machine is divided into multiple sections, each with its own magazine and transport path. This segmentation reduces the transport distance for bobbins within each section, significantly decreasing transport time while maintaining overall system simplicity through modular replication of transport units

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Bobbins are pre-loaded into sectionally arranged magazines at their respective locations rather than being transported from a central distance. This preliminary positioning of bobbins at needed locations eliminates long transport distances and reduces waiting time at winding points

Inventive Principle:
Principle #10Preliminary action

3Volume of stationary object

If different types of bobbins are stored in a single intermediate buffer, then storage space is saved, but the incorrect bobbin could block the way for the correct bobbin

Engineering Contradiction:
Improvestorage space utilizationVSAvoidcorrectness of bobbin supply
Core Design Contradiction:
Volume of stationary objectVSReliability

Solution Approach 1:

The intermediate storage is segmented into separate magazines for different bobbin types rather than using a single mixed buffer. This segmentation maintains compact storage space while ensuring that only correct bobbins are available at each winding point, eliminating the blocking problem and improving supply reliability

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Each sectionally arranged magazine is dedicated to storing specific types of bobbins appropriate for its location. This local specialization ensures that the correct bobbin types are stored and supplied at each winding point, preventing incorrect bobbins from blocking correct ones while maintaining efficient storage utilization

Inventive Principle:
Principle #3Local quality

AI summary

A spinning machine has a plurality of cross-winding units arranged side by side and on two longitudinal sides of the machine, each designed for winding yarn onto cores, the cross-winding units being grouped into a plurality of sections. One or more core magazines serve to store empty cores. A core transport device arranged along the cross-winding units supplies the cross-winding units with empty cores from the core magazine. Several core accumulators are arranged on each side of the machine for the distributed intermediate storage of cores, each cross-winding unit being assigned a single core accumulator for at least one core and/or several cross-winding units being assigned a multiple core accumulator for several cores, in particular at least some, preferably all sections, being assigned a multiple core accumulator.In a corresponding method for transporting sleeves in a spinning machine, different types of sleeves are stored in one or more sleeve magazines, and a suitable type of sleeve is supplied from the sleeve storage to the respective cross-winding device that requires the corresponding type of sleeve.
