Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional yarn spooling machines face challenges with high-mass yarn spools due to increased stress on bearings, bending stress, and difficulties in removal and transport, leading to precision issues and potential damage during winding and handling.
Innovation Solution
A yarn spool handling container with a rotatably supported spindle within a frame, allowing for reduced bearing stress and direct application of forces without affecting the spool, along with a spindle coupling element for drive torque transfer and a brake device for controlled unwinding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the accommodating capacity for yarn spool is increased, then the mass of the winding increases, but the stress on bearings and bending stress on spindle increase
Solution Approach 1:
The invention divides the system into two independent parts: the yarn spool handling container (with its own spindle and bearings) and the yarn spooling machine (with rotary drive). The container's spindle is supported by bearings within the container itself, not by the machine's spindle bearings. This segmentation allows the machine to handle only the lightweight container while the container handles the heavy yarn spool, resolving the contradiction between increased yarn capacity and reduced bearing stress.
Solution Approach 2:
The yarn spool handling container acts as an intermediary between the yarn spooling machine and the heavy yarn spool. The container's spindle and bearing system serves as a mediator that transfers the mechanical load away from the machine's drive system. The machine couples to the container's spindle coupling element to provide rotary motion, while the container's bearings support the actual weight of the yarn winding, thus resolving the stress issue.
2Productivity
If the mass of the yarn spool increases, then the yarn spooling speed decreases, but the handling and transport become more difficult
Solution Approach 1:
The system is segmented into the lightweight handling container and the heavy yarn spool. The machine handles and transports only the empty container, which is easy to maneuver despite the large yarn capacity. Once the container is in position, the heavy yarn spool is already contained within it, eliminating the need to handle the heavy spool separately. This segmentation resolves the contradiction between high spooling speed and ease of handling.
Solution Approach 2:
The yarn spool is pre-loaded into the handling container before the spooling process begins. This preliminary action means that during high-speed spooling and transport, the heavy yarn spool remains stationary within the container, and only the lightweight container needs to be moved or rotated. This resolves the handling difficulty that would otherwise accompany high-mass spools during high-speed operations.
3Ease of operation
If the yarn spool is removed from the spindle by pushing it axially, then the removal process becomes simple, but the high mass causes loss of the winding
Solution Approach 1:
The system separates the removal operation from the yarn spool itself. The entire yarn spool is removed as a complete unit from the container's spindle, rather than attempting to slide the heavy spool axially off the spindle. The container's spindle and bearing system is designed to accommodate the full weight of the yarn spool, allowing clean removal without disturbing the winding. This resolves the contradiction between simple removal and winding preservation.
Solution Approach 2:
The handling container acts as an intermediary that protects the yarn winding during removal. The container's spindle and bearing system provides a stable interface for the heavy yarn spool, allowing the spool to be removed intact from the container. The machine then receives the already-removed spool in the container, eliminating the need for axial pushing that would damage the winding. This mediator approach preserves manufacturing precision while maintaining ease of operation.
