To be successful in today’s demanding yarn market, modern spinning mill need to be fully focused on performance and quality of ring frame. So controlling of performance of ring spinning has good potential in future to obtain international quality level yarn.

Most of the spinners are in under the impression on that international quality means that all yarn quality specifications should be either equal to or better than USTER 25% values and they try very hard to attain that level by going good quality raw material and good machine performance. To analysis machine performance, the spinner is in position to check 100% of the material produced which is only possible by online monitoring system called as RING DATA. This paper broadly deals with overview of the need, design of system, working of system, uses, comparison with old methods, modern technology and future growth in RING DATA (online monitoring system).

Keywords: Ultimo System, Spider WEB, IMS, MMS, RING DATA.

RING DATA is online monitoring system which assess the performance of ring frame on machine itself with the help of sensor and embedded electronics. This system enables to locate the faulty yarn package and material. It is a powerful analysis tools allow instant identification of poor performing machine and spindles, resulting in faster reaction to problems and an increased efficiency and quality level with minimum efforts.

By considering need of online control most manufacture provide embedded online monitoring system in ring frame itself like RIETER, LMW, KTTM and others. Machine display provide information about production, end breakages, stop time, overall performance and power consumption of machine. USTER ring data is the most popular among other ring data system.

Need of Ring data:
In an olden day quality control is offline type. That is sampling the material from different spindle or machine or count wise and then testing of it is carried out. Then by comparing testing result either with norms or costumer requirement machine setting or other decision is taken. All this process of sampling, testing, analyzing and correcting action consumes more time with human error. All this is happening away from machine so called offline monitoring system. Quality monitoring by trial and error is outdated as is quality assurance and control from laboratory. So modern system approaches online monitoring on ring frame which will overcome drawbacks of offline monitoring.

Modern and efficient is linked online with production process; continuous monitoring and optimization of the production process are desire factor for consistent quality. Complete quality monitoring provides information on raw material and machine parameter.

Drawbacks of offline control:

  1. Required extra laboratory with equipped with modern testing instrument which increase cost.
  2. Sampling and testing is time consuming and may add human error.
  3. Corrective action is taken by observing result which may wrong.
  4. Saving of testing result which may difficult due to paper work.
  5. Calibration of testing instrument in specific time should done which increase cost.

Ring data has sensors which place at front roller and at spindle. They can performs several tasks as fallow,

  1. Detaching and signaling ends down.
  2. Detaching and reciprocating ends down.
  3. Detaching and recording ends down.
  4. Detaching and analyzing ends down.
  5. Recording stoppages
  6. Recording output
  7. Calculating efficiency
  8. Roving stop motion in the events of end down.

These data is feeded as input to machine or monitoring software. Software are made such that they compare input with standard result or costumer requirement if any match is not found machine give signal to operator or by adjusting automatic machine setting error get corrected as well as production, extremely helpful to mill for,

  1. Assessing spinning behavior of raw material.
  2. Assessing production behavior of machine.
  3. Establishing causes of faults, overall and per spindle.
  4. Assessing climatic influence.
  5. Operator guidance by proper signaling.
  6. Workplace loading.
  7. Personnel rating.
  8. Cost calculation.

There are two types of ring data monitoring system as fallow,

A) Machine Monitoring System:

USTER ring data Monitoring System

In this system travelling sensor runs continuously back and forth at the height of ring rail of an each side of the machine on single machine or all machines. This generates magnetic field that is affected by the rapidly rotating traveller. If yarn breaks occur, traveller ceases to rotate and sensor display resulting impulse as an ends down, downtime and repaired time.

Another sensor fitted on front roller records delivery speed and machine stoppages and number of doff and duration.

All the information collected is transmitted to the computer with monitor and printer which performs the necessary analysis and stores data for preset periods .Report from printer contains data per machine, blends or installation. Following data are given in reports,


B) Individual spindle monitoring system:

In this system optical sensor on the ring frame at each spinning position, which is assessing the motion of traveller. Each spindle has individual sensor which provide more control than MMS. More and more spinning operations want to monitor the individual ring spindle for yarn breaks and spindle speed. IMS, based on an individual optical sensor for each spindle, detects run/stop and speed, monitors the ends down level and reports slipping spindles.

One mouse click on a particular ring frame allows the user to select any detailed report, such as spindles with the highest breakage level, slipping spindles per machine, yarn breaks as function of the bobbin build up, and during up and down movement of the ring rail, Stops are always assigned to the right spindle, regardless the length of the machine. Ends down levels, slipping spindles, frame and spindle efficiency are reported by doff, as well as by shift, day, week and month. Trend reports highlight recurring problem spindles.

Advantage of IMS ON MMS:

  1. No moving parts in system.
  2. No maintenance due to less moving parts.
  3. Continuous monitoring of all spindles.
  4. Each and every spindle is under in supervision and control.

Architecture of system at machine:

Automation in RING DATA:
Automation in spinning is always integral part of old system, which will improve product quality. Automation in spinning system always try to achieve 100% efficiency, highest production, less human work, more control on process with maintaining international quality yarn.

Online quality monitoring on ring frame is itself a new development since in last decade. Now latest technology is trying to control system with using mobile and tablet by APP and data demand through massages request.

Server of system is connected to web server. Server has stored data and ongoing production data. Web server is connected to internet which will store data on internet in protected manner. Mobile or tablet should have installed app of that control system which can assess control system. Mobile owner or mill owner only can change machine or other setting. Only owner can see reports and all mill data or ringframe data. Now rieter has developed android based mill control system with name SPIDER-WEB mill control.

Spider web is modern user oriented windows based data system below figure shows the corresponding data flow the mill in schematic form within the mill this data flow is based on Ethernet. This both simplifies data management and enables data loss to be prevented efficiency. Data are stored in 3 locations for this purpose.

  1. On the machine until is they are written onto the customer’s pc.
  2. On the hard disc of the host pc, until are written into Spider web database for up to one year external backup.
  3. In the spider web database for up to one year. External backup of this database is possible.

These systems mostly feature a three or four-level structure, starting at the lowest level, i.e. the level at which sensitive sensors are installed directly at special control points on the machines. They pick up the incoming figures and transmit them to the second level, the machine level. At the machine level, simple computers collect, transform and evaluate the signals arriving from the sensors. The summarized result is often indicated in a simple manner on a panel at the machine, informing the personnel responsible and enabling them to react immediately.

The third level is the level of the PC workstation, where the data collected at the machine level is selectively evaluated and informatively displayed in the supervisor‘s office, often also in graphic form. The top level of the MIS is usually a commercial host computer.

Here again, all information arriving from the third (or perhaps second) level is collected in a condensed and compatible form by a local network and selectively evaluated in an easy-to-use form,The detailed analysis of the second, third and fourth level enables immediate action to be taken if the slightest deviation occurs.

As demand of yarn increasing due to more consumption of textiles it necessary that provides that much yarn to market without compromising in yarn quality. It is possible only when quality should maintain throughout process. Spinning of yarn is important for yarn quality so by online monitoring at ringframe it can possible to maintain. Leading spinner is using embedded online monitoring system on ringframe. It provides easy setting, easy working to operator, data storages, less paper work. As demand of ring data increases number of research taken place in system also increased in last decade. Beyond the online process control man are trying control whole mill by smart phone. Controlling spinning by means of mobile has great potential in future controlling system ring frame. By this new ring data system working of mill and highest quality of yarn is possible with high author security.
