Segmented Suction Channels in Ring Spinning Machines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ring spinning machines require high energy for suction devices due to large vacuum sources needed to overcome friction losses in machine-long suction ducts, leading to significant energy consumption, which is costly and inefficient.
Innovation Solution
The design allows for the connection of suction tubes in machine sections to be switched between a vacuum source and a machine-long suction channel, using a controlled slide element to minimize friction losses and reduce the size of necessary fans, with integrated filter elements and a sensor-controlled drive mechanism for cleaning, and optional connection to the spinning mill's air conditioning system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If machine-long suction channels are used to connect all spinning positions to a central filter device, then the system structure is simplified, but friction losses increase and energy consumption rises
Solution Approach 1:
The suction system is divided into multiple independent suction channels, each serving a specific machine section with its own vacuum source and filter device. This segmentation reduces the length of individual suction channels, thereby reducing friction losses and energy consumption while maintaining system functionality.
2Ease of operation
If a single large vacuum source serves the entire machine, then the system is simpler to operate, but the vacuum source must be dimensioned large leading to high energy consumption
Solution Approach 1:
The single large vacuum source is replaced by multiple smaller vacuum sources distributed along the machine. Each vacuum source serves only its local machine section, reducing the power requirement of each individual source while collectively providing sufficient vacuum for the entire machine.
Solution Approach 2:
Each machine section is equipped with its own vacuum source and filter device, allowing the vacuum system to be optimized locally for each section's specific requirements rather than using a uniform approach for the entire machine.
3Object-affected harmful factors
If additional suction devices with filter elements are installed at each work station, then dust removal during regular operation is improved, but the design effort and cost become considerable
Solution Approach 1:
Instead of equipping each individual work station with separate suction devices, the machine is divided into sections, with each section having one suction device with a filter element. This reduces the total number of suction devices while still providing effective dust removal for all work stations within a section.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach reduces the energy required for generating negative pressure, lowers operational costs, and ensures efficient cleaning of filter elements while maintaining sufficient vacuum levels, making the system more cost-effective and energy-efficient.
Implementation Method 1
a vacuum source, preferably a fan
Implementation Method 2
The suction devices, which not only dispose of dust and fluff, but are also used in the event of a yarn break, are connected to filter devices via machine-long suction channels
Implementation Method 3
each opens into a filter device in the machine area, which is equipped with a correspondingly smaller vacuum source

AI summary
The machine (1) has section-wise arranged spinning areas positioned next to each other on both sides of a machine longitudinal axis. Each area has suction pipes (10) in an area of a stretching unit arrangement (5) attached at a negative pressure-subjectable filter device (20) by a suction channel (12). The pipes are connected to a negative pressure source i.e. electric motor driven ventilator, or the channel by actuating a defined controllable slider element (13) that is engaged into a channel part (11), where the negative pressure source is arranged at the channel part.
