Textile Machine Suction Segmentation for Energy Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing textile machines with magazine-type bobbin feeding mechanisms require strong suction currents, leading to increased costs, larger device sizes, and energy wastage due to the need for powerful driving sources and continuous suction even when winding is stopped.
Innovation Solution
A textile machine design featuring separate suction current generating mechanisms for yarn waste collection and yarn end holding, using distinct driving sources to optimize suction power and reduce energy consumption by only activating necessary components during specific operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single duct supplies negative pressure to both the magazine and guiding members, then the structure is simplified, but a large output driving source is required resulting in increased cost and device size
Solution Approach 1:
The single duct system is segmented into multiple independent ducts: a first duct supplies negative pressure to the magazine for bobbin feeding, while second ducts supply negative pressure to guiding members for yarn guidance. This segmentation allows each duct to use smaller, more cost-effective driving sources rather than requiring one large-power driving source to supply all locations simultaneously.
2Device complexity
If a single duct supplies negative pressure to both the magazine and guiding members, then the structure is simplified, but the driving source size increases
Solution Approach 1:
The duct system is divided into separate first and second ducts with independent driving sources. The first driving source serves only the magazine, and the second driving source(s) serve only the guiding members. This segmentation allows selection of appropriately sized driving sources for each function, reducing the overall device volume compared to a single large driving source.
3Reliability
If suction current is generated in both the magazine and guiding members during bobbin feeding, then yarn end holding is effective, but energy wastage occurs when winding is stopped
Solution Approach 1:
The system implements dynamic control where the first duct (supplying the magazine) and second ducts (supplying guiding members) can be independently activated. During bobbin feeding operations, both ducts operate to ensure reliable yarn end holding. When winding is stopped and only bobbin feeding is required, only the first duct needs to operate, reducing energy consumption compared to having suction continuously active in both locations.
Solution Approach 2:
The suction current generation is made periodic and task-dependent rather than continuous. The first duct operates periodically during bobbin feeding tasks, while the second ducts operate periodically during yarn guidance tasks. This periodic activation aligned with actual operational needs reduces energy wastage compared to continuous suction in all components.

AI summary
A lower yarn guiding pipe (25) and an upper yarn guiding pipe (26) suck and collect yarn waste generated in a winder unit (4). A first suction current generating mechanism (40) includes a negative pressure electric motor (42) that generates a first suction current in the lower yarn guiding pipe (25) and the upper yarn guiding pipe (26). A yarn end holding section (63) sucks and holds a yarn end of a yarn supplying bobbin (21) accommodated in a pocket (62p) of a magazine-type bobbin feeding mechanism (60), and collects generated yarn waste. A second suction current generating mechanism (50) generates a second suction current in the yarn end holding section (63) by the action of a negative pressure electric motor (52) that is different from the negative pressure electric motor (42).
