Spinning Mill Fiber Feeding Control for Continuous Weighed Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing food supply systems in spinning mills face inefficiencies due to inconsistent fiber material delivery, leading to stop-and-go operations, increased energy consumption, and production delays, primarily because the air-fiber flow is not continuous, and manual production settings lack synchronization.
Innovation Solution
A method and system that includes a receiving device and feeding devices with a weighing process divided into rapid and slow phases, adjusting operating speeds based on individual device performance to ensure timely delivery, and a transport section speed adjustment to maintain continuous production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional control systems with separate control units for each machine are used, then each machine can be controlled independently, but the system complexity increases and coordination between machines becomes difficult
Solution Approach 1:
The patent combines multiple separate control units into a single centralized control unit that manages all spinning machines. This control unit receives production targets from a planning system and automatically distributes tasks, monitors machine status, and coordinates operations across all machines, thereby reducing system complexity while improving coordination.
Solution Approach 2:
The centralized control unit performs multiple functions including task distribution, real-time monitoring, alarm management, and production optimization across all spinning machines. This multi-functional approach replaces multiple specialized control units, simplifying the overall system architecture while maintaining comprehensive control capabilities.
2Productivity
If manual monitoring and adjustment of spinning machines are performed, then operational flexibility is maintained, but productivity decreases and labor costs increase
Solution Approach 1:
The spinning machines are equipped with sensors and automated systems that continuously monitor their own operational parameters such as yarn tension, speed, and temperature. The centralized control unit receives this data and automatically adjusts machine parameters or triggers alarms without requiring manual intervention, enabling the system to serve itself and maintain optimal performance continuously.
Solution Approach 2:
The system implements continuous feedback loops where sensors monitor machine status and yarn quality parameters in real-time, transmit data to the centralized control unit, which then automatically adjusts operational parameters or alerts operators. This closed-loop feedback mechanism ensures rapid response to deviations, maintaining high productivity without manual monitoring.
3Manufacturing precision
If frequent quality checks are performed during spinning production, then product quality is improved, but production time is lost and productivity decreases
Solution Approach 1:
The patent replaces manual quality inspection with automated optical and sensor-based monitoring systems integrated into the spinning machines. These systems continuously measure yarn diameter, tension, and other quality parameters in real-time during production, eliminating the need to stop the machine for manual checks while maintaining consistent quality standards.
Solution Approach 2:
The automated quality monitoring system operates continuously during spinning production without interrupting the manufacturing process. Sensors continuously scan the yarn as it is being produced, providing real-time quality data to the control unit, which can make immediate adjustments without stopping production, thereby maintaining both quality and productivity.
4Loss of energy
If traditional energy consumption patterns are maintained in spinning machines, then operational simplicity is preserved, but energy costs increase and environmental impact worsens
Solution Approach 1:
The spinning machines incorporate dynamic energy management that adjusts operational parameters such as motor speed, heater power, and air flow based on real-time production requirements and machine load. The centralized control unit optimizes energy consumption by coordinating operations across all machines and adjusting parameters dynamically rather than maintaining fixed settings, reducing overall energy usage while adapting to changing production conditions.

AI summary
The invention relates to an operating method for a feeding installation (1) comprising a receiving device (30) to be fed and at least one feeding device (2, 10). The feeding device (2, 10) is designed to weigh fibrous material of a predetermined quantity in a cyclical manner and then to deliver said fibrous material to the receiving device (30). The method comprises a cycle (Z) including weighing the associated quantity of fibrous material in each feeding device (2, 10). Once a current cycle time dependent on or predetermined by the receiving device (30) has passed, minus a delivery time belonging to each of the at least one feeding devices (2, 10), a check is carried out as to whether each of the at least one feeding devices (2, 10) are capable of having weighed the associated quantity of fibrous material and having delivered said fibrous material to the receiving device (30) when the current cycle time has passed. If each feeding device (2, 10) is capable of doing so, the associated quantity of fibrous material is delivered to the receiving device (30). Otherwise, the working speed of the feeding device(s) (2, 10) which is or are not capable of doing so is increased by a predetermined amount. A spinning mill installation (1) is constructed and designed to be operated according to said method.
