Swingable Working Platform for Spun Yarn Take-Up Apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing spun yarn take-up apparatuses require increased space for installation due to the need for a separate operation space for yarn threading, which obstructs bobbin attachment and removal, especially when the godet roller is arranged parallel to the bobbin holder, and sharing a working platform among multiple units complicates simultaneous threading operations.
Innovation Solution
A spun yarn take-up apparatus with a working platform that can selectively take an operation posture for yarn threading and a retracted posture to avoid obstruction during bobbin attachment and removal, featuring a swingable footboard and storage system to minimize horizontal size and prevent interference with the bobbin holder.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the godet roller is arranged parallel to the bobbin holder on the leading end side to enable yarn threading without separate space, then the installation space is reduced, but the working platform obstructs bobbin attachment and removal
Solution Approach 1:
The working platform is made movable rather than fixed, allowing it to shift between obstructing and non-obstructing positions. The platform can be moved along the leading end side of the bobbin holder, enabling operators to access the godet roller for yarn threading while clearing the path for bobbin attachment and removal operations.
Solution Approach 2:
The working platform is divided into multiple segments or sections that can move independently. This segmentation allows the platform to be reconfigured - extending to provide working space for yarn threading, then retracting or shifting to clear the bobbin holder area for bobbin operations.
2Area of stationary object
If a common working platform is shared among multiple spun yarn take-up apparatus to reduce space, then the apparatus structure becomes complicated due to rails and movement mechanisms
Solution Approach 1:
Instead of one complex shared platform, each spun yarn take-up apparatus has its own independent working platform. This segmentation eliminates the need for complex rail systems and coordination mechanisms, while still achieving space efficiency through compact individual platform designs.
Solution Approach 2:
The working platform design is replicated for each spun yarn take-up apparatus rather than creating a complex shared system. This copying approach simplifies the overall structure by using multiple simple, identical units instead of one complicated shared mechanism.
3Productivity
If a single working platform is shared among multiple units to enable simultaneous threading, then the platform must be movable which complicates the structure with rails
Solution Approach 1:
Each spun yarn take-up apparatus has its own dedicated working platform, allowing simultaneous threading operations across multiple units without requiring a shared movable platform. This segmentation enables independent operation of each platform while maintaining productivity.
Solution Approach 2:
The working platform design is universal and can be applied to multiple spun yarn take-up apparatus units. Each unit has its own platform that performs the same function, enabling simultaneous operations without the need for complex shared mechanisms.

AI summary
Onto godet rollers 21 to 24 arranged in parallel with a bobbin holder 7, a yam threading operation can be performed from the leading end side of the bobbin holder 7. A working platform 33 is able to selectively take an operation posture in which footboards 41 and 42 extend in the horizontal direction and a retracted posture in which the footboards 41 and 42 extend in the vertical direction. In the operation posture, the working platform 33 is located on the leading end side of the bobbin holder 7. The operation posture is taken when the yarn threading operation is performed. The retracted posture is deviated from a yarn winding device 3 with respect to an alignment direction. A storage 31 having a slidable component 32 stored therein is provided laterally to the yarn winding device 3. The working platform 33 is attached to the slidable component 32. Moving the slidable component 32 in the winding axis direction with the working platform 33 taking the retracted posture causes the working platform 33 to be stored into the storage 31.
