QQM-3 system

What is QQM-3 ?

QQM-3 is a portable instrument for quick operative quality control of yarn in spinning mills.

Present activities

... problems with quality of yarn ?

www.textil.cz/qqm

Such pictures are well-known only to machine operators and/or to the peoples responsible or for quality control and claims.

www.textil.cz/qqm

Such woven fabric quality should not leave the plant.

www.textil.cz/qqm

If such fabric is sold to a customer, then in most cases a claim can be expected which leads to high financial losses.

www.textil.cz/qqm

In this case a yarn with a moiré effect is concerned.

www.textil.cz/qqm

In this case, the greatest problem for the manufacturer is to identify the spinning unit (SU) which produces defective yarn.

Troubleshooting 3

www.textil.cz/qqm

QQM-3 is the abbrevation for the English name

Quick Quality Measuring.

The digit 3 means the third series in its devepolment.

The third possibility - the use of the QQM-3 device that enables them to reveal the spinning units productions a

lower quality yarn directly, in time and with minimum costs and to remove the defects without delay.

www.textil.cz/qqm

QQM-3 system is based on the optical principle by means of an infrared sensor (2 mm measure interval). It means that it is not dependent

on standard atmosphere (const. humidity and temperature) - it is not necessary to condition the yarn before measuring.

System QQM-3 detect „optical“ defects !

PROPERTIES - optical princip of measuring

www.textil.cz/qqm

QQM-3 is a device designed for the application in the spinning mills but it does not rule out the possibility of its laboratory use (as matches format

and range of results). Its minimized dimensions, mechanical resistance and an autonomous power supply allow to measure the yarn quality directly in

the course of its manufacturing - no destruction tests are necessary.

PROPERTIES - operation device

www.textil.cz/qqm

For a quick rough measuring it is sufficient to scan about 10 meters of yarn. A rotor spinning machine is reliability measured within 60 min including an evaluation. Unlike laboratory procedures here the operator can carry out an intervention in the production process immediately

after the measuring. At least to stop production of rejects.

PROPERTIES - quickness and instant reaction

www.textil.cz/qqm

The QQM-3 device enables to carry out a 100% operation control of all SU‘s and indicate units producing faulty yarn . By ONE device is possible measuring on more machines

of different types and technologies (unlike the ON-LINE sensors). It increase utility value of QQM-3 system.

PROPERTIES - portability

www.textil.cz/qqm

System QQM-3 scan optical picture of yarn by measuring head, which operating staff put into yarn delivery way. It allows measuring both on the OE rotor and on the ring spinning machines. Operation staff have to choose right technology before each measuring only.

Universálity consists in independence of color, rough and type of yarn.

PROPERTIES - universality

www.textil.cz/qqm

PROPERTIES - modularity

QQM-3 system has 4 types of measuring

1. INDICATION- measuring time about 10 sec- comparing of quality in terms CV% 10 meters of yarn

2. MEASURING- measuring time about 1-3 min- detailed measuring of yarn

3. ANALYSIS- measuring time about 3-10 min- detailed measuring of yarn and spectral analysis

4. DATA SOURCE- data gathering for analyse on PC

( only ONE hardware with software modules )

www.textil.cz/qqm

INDICATIONmeasuring time about 10 sec (depending on delivery speed)

Results:

- particular CV% for each SU- graph of a CV% values (fault SU blinking)- view table of fault SU

Effect: - detection of faulty SU on machine- quick technical examination of spinning machine- increasing quality of production

www.textil.cz/qqm

INDICATION

www.textil.cz/qqm

MEASURINGmeasuring time about 1-3 min

(depending on measured length and delivery speed)

Results:

- Y.C. (yarn count - fineness [TEX]) - U%, CV%, CV% in cut lengths- indicators IPI (thin and thick places, neps)

Effect: - quick and detailed informations about quality of producing yarn

www.textil.cz/qqm

MEASURING

www.textil.cz/qqm

ANALYSIS

Results:

- Y.C. (yarn count - fineness [TEX]) - U%, CV%, CV% in cut lengths- indicators IPI (thin and thick places, neps) - spectrogram (show graph of spectral analysis)

Effect: - quick and detailed informations about quality of producing yarn - spectrogram can be used for specificat. of defects

same as measuring module, but included moreover spectral analysis

(must be measurem min. 100-300 meters of yarn !)

measuring time about 3-15 min (depending on measured length and delivery speed)

www.textil.cz/qqm

ANALYSIS

www.textil.cz/qqm

DATA SOURCE

Results:

- data file for analyse on PC

Effect: - quick measuring of yarn (without instant calcualation)

- possibility of individual processing of results (suitable for research, special analyse, ...)

measuring time about 1-15 min (depending on measured length and delivery speed)

www.textil.cz/qqm

The delivery also includes a software for a PC (with OS Windows95 and newer). SW allows measured data to archive, edit, back up, … .

HANDICAPS:

- optical principle (optical faults, various materials, colours, ...)

- quick mesuring and instant reaction

- conjunction of operational & labor. device (4 typy měření)

- for several OE rotor and ring spinning machines

- portability - simply portable device (about 3 kg)

- very low purchase and minimum operation cost

- not fully automated process - necessary of attendat operator

Assembly of QQM-3 system

Basic part of the QQM-3 system is measuring head [1], which scan a picture for every 2mm of yarn. By the help of cable [5] and converter [4] it can be connected to the terminal PSION [2]. There are scanned data

processed and displayed results.This confiration is fully functional.

System QQM-3 also included charging unit with additional battery [3], portable stand and reduction for ring-spinning machines.

Open the way to Total Production Maintenance !!!

QQM-3 system does not only discover that spinning quality tends to degrease - can give you also the idea what could be the reason for this tendency.

Ussualy, if this tendency is already discovered, you have time to decide about the maintenance

action without immediate break of spinning process.

What can you win withQQM-3 system ???

- claim decrease

- stabile quality

- higher mills capability utilization rate

- decrease in needs of replacement parts

- maintenance capacity saving
