Yarn Feeding Package Carriage with Fixed Peg-Shaft Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing yarn feeding package conveying carriages have a complex structure due to the need for a package movement member that moves in the axis direction of the peg shaft, leading to increased manufacturing costs and the ability to convey only two packages at a time.
Innovation Solution
A yarn feeding package conveying carriage with a peg shaft and a positioning member that is immovably attached between two positions along the axis direction, allowing easy positioning of multiple packages at a predetermined extraction point without a complex structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a package movement member is provided to position yarn feeding packages at a predetermined extraction position, then positioning accuracy is improved, but device complexity increases
Solution Approach 1:
The patent applies preliminary action by pre-positioning the yarn feeding package at a predetermined extraction position using a positioning member that is immovably attached to the peg shaft. The positioning member includes a positioning protrusion that engages with a positioning groove on the package, ensuring the package is already at the correct position before extraction, eliminating the need for complex movable positioning mechanisms.
Solution Approach 2:
The patent segments the positioning function from the support function by providing separate positioning members and support members on the peg shaft. The positioning member specifically handles positioning accuracy while the support member handles package support, allowing each component to be optimized independently and reducing overall device complexity.
2Productivity
If a package movement member is provided to convey multiple packages, then productivity is improved, but device complexity increases
Solution Approach 1:
The patent applies universality by designing the peg shaft to serve multiple functions: it provides support for the yarn feeding package through support members, positioning through positioning members, and enables extraction of multiple packages. The same peg shaft structure handles both positioning and support functions, eliminating the need for separate complex movement mechanisms and allowing multiple packages to be conveyed efficiently.
3Quantity of substance
If the peg shaft is made long enough to hold two packages side by side, then quantity of packages is improved, but positioning difficulty increases
Solution Approach 1:
The patent applies local quality by providing different functional regions on the peg shaft: positioning members are provided at specific locations to engage with positioning grooves on packages, while support members are provided at other locations to support packages. This localized functional differentiation allows multiple packages to be held on a long peg shaft with each package independently positioned and supported, reducing positioning difficulty.

AI summary
It is possible to provide a yarn feeding package conveying carriage allowing each of a plurality of yarn feeding packages aligned along an axis direction of a peg shaft to be positioned at a predetermined extraction position in the axis direction of the peg shaft, and allowing suppression of complications of the configuration and increases in manufacturing cost. A yarn feeding package conveying carriage 1 includes a carriage body 21, a peg shaft 22 extending in a cantilever manner from the carriage body 21 and on which a yarn feeding package 10 is to be hung, and a positioning member 23 provided to the peg shaft 22. The peg shaft 22 is provided with a first position P1 and a second position P2 aligned along an axis direction of the peg shaft 22 and at which the yarn feeding package 10 is to be hung. The first position P1 is provided as a position closer to the tip and the second position P2 is provided as a position closer to the carriage body 21 in the axis direction of the peg shaft 22. The positioning member 23 is provided in such a manner as to be engaged with the yarn feeding package 10 hung at the first position P1 to the yarn feeding package 10 at the first position P1.
