Ring spinning for smooth functioning of machineryUster Sentinel enables practical optimisation for managers and shop floor personnel Uster, Switzerland, 10th December 2019: Even in the best ring spinning mills, there is always room for improvements, among a complex range of options management and operatives need to consider for optimised productivity and profit. Uster Sentinel provides a fact-based overview of spinning machine performance, pinpointing real opportunities for excellence in the use of technology, components, and manpower.

Wide-ranging benefits in ring spinning

“We invested in Uster Sentinel ring spinning optimization system with the goal to improve profits but we are delighted that staff also likes the installations,” says Vrajesh Kikani, Managing Director, Kikani Exports. The mill reports a positive impact on profitability resulting from successful optimization of a number of factors, such as waste, ring traveler lifetime, machine speed and energy consumption etc. The production focuses on 100 percent cotton combed compact yarns, in the count range Ne 20 to Ne 40, for weaving and knitting end-uses. 

Uster Sentinel also monitors the productivity of all spindles, feeding back all the required links and information to help yarn producers make optimisation decisions at ring spinning based on reliable data.

Among potential problems for all spinners is inconsistent yarn quality characterized by low twist, caused by loose fibers blocking travelers especially excessively worn ones. Only Uster Sentinel can identify spindles malfunctioning in this way, since the issue does not cause end- breaks but still produces yarns which are too weak for high-speed warping and weaving machines. Ring spinning for smooth functioning of machinerys

The unique Off-Standard feature of Uster Sentinel safeguards against ‘hidden ‘quality risks such as this.

Fact-based feel-good advantages

Reports give status information at five-minute intervals, including end-breaks and piecing during that period. “Information about piecing speeds helps me to identify each operator’s skill level so that I can optimize the operation schedules and processes. Only by assigning manpower carefully it is possible to maintain ideal working conditions,” says M. Kannan, General Manager. Uster Sentinel handles complete personnel management, including shift planning and staff assignment for all machines in the system integrated with monitoring of critical ring spinning parameters. 

This makes personnel management in ring spinning fact-based and less time-consuming. Reliable detection of slip, rogue and idle spindles is what makes Uster Sentinel popular among shop floor staff. LEDs indicate spindles showing an issue or positions where an end-break occurs, directing personnel quickly to fix the problem. Incidents are also shown on the machine display, providing an overview of spindles where attention is needed. 

Bobbin build-up report gives practical support

End-break levels are a key indicator of ring spinning performance and Uster Sentinel recognizes this by providing an intuitive bobbin build-up report for every parameter influencing end-breaks. Spinners can then initiate improvements relative to their own mill, taking account of ambient conditions and energy consumption, as well as machine speed, wear of mechanical parts and personnel.

Comprehensive analysis of the speed curve and its impact on quality throughout cop build-up is a key element of the enhanced way of optimizing ring spinning performance. Cop build-up quality is the new dimension of optimization, enabling managers to select the correct machine settings for higher production yields, while keeping quality at the desired levels. Furthermore, it is now possible to compare ring spinning performance between different machines.
