Energy-Saving Solution with Efficient Yarn Pick-Up
Fig.1: Energy saving and highly efficient suction nozzle in operation
Energy efficiency is key for any operation on the automatic winding machines. The new suction nozzle upgrade not only improves upper yarn pick-up but also minimizes energy costs thanks to possible vacuum reductions. Additionally, the Smartjet upgrade helps to further increase efficiency in upper yarn searching as manual intervention is eliminated. This translates into an increase in production due to less machine downtime, significantly reduced operator workload and greater process reliability.
The winding unit cycle time is highly dependent on how fast and effectively the cut yarn is picked up from the package. The upgrade consists of the latest upper yarn pick-up suction nozzle (Fig.1), which is used in the latest automatic winding machine Autoconer X6. The standard suction nozzles will be replaced with new, flow-optimized and highly effective suction nozzles. Thanks to the aerodynamically optimized inner and outer moulds, the new suction nozzle offers extremely efficient air guidance. This benefits in maximum upper yarn pick-up reliability and minimized energy costs, which are possible through vacuum reduction.
The improved new upper yarn pick-up suction nozzle also protects the package surface, especially while processing fine yarn counts. The upper yarn sensor in the suction nozzle detects the yarn precisely and stops the suction which is why the yarn pick up is so efficient and reduces yarn waste. The frequent stoppage of the winding position and manual interventions are eliminated due to the efficient yarn pick-up from the package.
Unique Smartjet Power Nozzle
The unique Smartjet power nozzle is installed on the doffer unit (Fig.2). This helps increase the efficiency of the upper yarn suction nozzle even further. Before a winding position activates a red light due to the non-identification of a yarn end from the package, it sends the signal to the doffer unit. The Smartjet power nozzle efficiently supports the upper yarn search, thereby increasing the success rate of the upper yarn pick-up during the winding unit cycle process.
The graph (Fig.3) demonstrates the advantage of the Smartjet upgrade. This can lead to up to 2% increase in yarn production. Additional benefits are that operator workload is significantly reduced as employees no longer need to manually search for upper yarn. Process reliability is also improved.
