Spinning Device Template Thread Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing spinning devices require frequent replacement of supply spools and maintenance to adapt to different threads, leading to inefficiencies and errors, especially in modern machines that spin multiple threads.
Innovation Solution
A spinning device with a template thread device that stores a reusable template thread independently of the spun thread, allowing each workstation to spin a new thread independently without relying on a mobile service device, and a service device that refills the template thread when necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a mobile service device with auxiliary yarn supply is used, then thread supply flexibility is improved, but device complexity and maintenance intensity increase
Solution Approach 1:
The system is divided into independent workstation units, each equipped with its own template thread device. This segmentation eliminates the need for a centralized mobile service device, reducing overall system complexity while maintaining thread supply flexibility at each station.
Solution Approach 2:
Each workstation is equipped with a template thread device that automatically supplies template threads without requiring external service intervention. The system serves itself by locally storing and providing the necessary threads, eliminating dependency on mobile service devices.
2Reliability
If supply spools must be matched to thread types, then thread compatibility is ensured, but operational time and maintenance intensity increase
Solution Approach 1:
Template threads are pre-stored in the template thread device at each workstation before being needed. This preliminary preparation allows immediate use of the correct template thread without requiring time-consuming spool replacement or matching operations when thread changes are required.
3Adaptability or versatility
If multiple auxiliary threads are kept for different spinning operations, then operational versatility is improved, but device complexity and thread consumption increase
Solution Approach 1:
The template thread device provides a universal template thread that can be used for multiple spinning operations and thread types. This single multi-functional template replaces the need for multiple specialized auxiliary threads, reducing total thread quantity required while maintaining operational versatility.

AI summary
The present invention relates to a spinning device (1), in particular a rotor spinning device or air spinning device, with a plurality of, preferably self-contained, working stations (2), each of which has a spinning station (3) for producing a thread (5) and a winding station (4) for winding the thread (5) onto a cross-wound bobbin (6), wherein the winding station (4) has a sleeve holder (8) for receiving a sleeve (7), a winding roller (9) for driving the sleeve (7) orThe spinning device (1) comprises a cross-wound bobbin (6) and a changing device (10) for laying the yarn (5) on the cross-wound bobbin (6), and the spinning station (3) has several individual drives and/or the winding station (4) has at least one individual drive each for the winding roller and the changing device. The device also includes a method for spinning a yarn (5) in a preferably self-contained working station (2) of a spinning device (1) with a feed yarn (23), which is fed to the spinning station (3) for spinning a yarn by a handling device (27), and wherein the spun yarn is transferred to an empty spool (7). Each working station (2) is assigned at least one feed yarn device (22) with a feed yarn (23) suitable for spinning the yarn (5) onto an empty spool (7), wherein the feed yarn (23) is stored independently of the spun yarn (5).
