Solution Overview

Problem

The existing spun yarn take-up apparatus requires manual and time-consuming positioning of a suction gun to thread yarns into a yarn path regulatory guide, leading to increased yarn discard and production costs due to difficulties in maintaining the suction port's position during yarn threading.

Innovation Solution

A spun yarn take-up apparatus with a positioning portion that aligns the suction port downstream of the yarn path regulatory guide, allowing for easier yarn threading by positioning the suction port at a predetermined location, and includes a yarn swing suppressor to minimize yarn movement and contact with the positioning portion, reducing yarn discard and production costs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual positioning of the suction gun is used for threading yarns to the yarn path regulatory guide, then the suction port can be positioned at a suitable working location, but it takes time to position and keep the suction port at the suitable location, increasing yarn discard and production cost

Engineering Contradiction:
Improveyarn threading operationVSAvoidthreading time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The suction gun is equipped with a positioning portion that automatically guides and positions the suction port at the predetermined working location downstream of the yarn path regulatory guide. This self-positioning mechanism eliminates the need for manual positioning operations, allowing the suction port to automatically align with the groove portions when threading yarns, thereby reducing threading time and yarn discard while maintaining ease of operation.

Inventive Principle:
Principle #25Self-service

2Manufacturing precision

If manual positioning of the suction gun is used, then the operator can hold the suction port at the suitable working location, but it is difficult to maintain the position during yarn threading, leading to increased yarn discard

Engineering Contradiction:
Improvesuction port positioning precisionVSAvoidyarn discard
Core Design Contradiction:
Manufacturing precisionVSLoss of substance

Solution Approach 1:

The positioning portion acts as an intermediary structure between the suction gun and the yarn path regulatory guide. It provides a predetermined position that automatically aligns the suction port with the groove portions, serving as a mediator that ensures precise positioning without requiring manual intervention. This intermediary mechanism maintains consistent positioning precision during yarn threading, preventing yarn discard caused by positioning errors.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of manufacture

If the suction port is positioned downstream of the yarn path regulatory guide, then yarn threading is facilitated by overlapping yarns with groove portions, but the suction gun must be precisely positioned to achieve proper alignment

Engineering Contradiction:
Improveyarn threading processVSAvoidpositioning structure
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The positioning portion is designed to preliminarily position the suction port at the predetermined location downstream of the yarn path regulatory guide before the actual yarn threading occurs. This preliminary positioning action ensures that the suction port is already aligned with the groove portions when yarns need to be threaded, facilitating the threading process without adding complex positioning mechanisms during operation.

Inventive Principle:
Principle #10Preliminary action

AI summary

An object of the present invention is to achieve easy yarn threading to a yarn path regulatory guide. A spun yarn take-up apparatus 1 is configured to wind yarns Y by means of a yarn winding apparatus 4. The yarns Y are spun out from a spinning apparatus 2. The spun yarn take-up apparatus 1 includes (i) a yarn path regulatory guide 7 which includes groove portions 71 aligned in a left-right direction orthogonal to a yarn running direction and which is configured to restrict movement in the left-right direction of the yarns Y aligned in the left-right direction by causing the yarns Y to run in the groove portions 71 and (ii) a positioning portion 31 configured to position a suction port 40a of a suction gun 40 at a predetermined position which is downstream of the yarn path regulatory guide 7 in the yarn running direction and where yarn threading to the yarn path regulatory guide 7 is possible. In this regard, the yarns Y run in the yarn running direction.
