QQM4 new portable device for Quick Yarn Quality Measuring QQM4 is the unique portable equipment designed for a direct and quick quality control of yarn in process – no interruption or any adjustment of yarn is needed. It enables to analyse yarn quality very quickly and directly on the machine in operation. QQM technology is based on optical principle and its application in spinning process eliminates defects visible after weaving and dyeing (e.g. moiré effect, naps).

... problems with quality of yarn ?
qqm@vubas.cz www.QQM.cz

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

3. Such woven fabric quality should not leave the plant.

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

5. In this case a yarn with a moire effect is concerned.

6. The greatest problem for the manufacturer
is to identify the spinning unit
which produces the faulty yarn.

13. what is
QQM system ???

14. QQM 4 is the abbreviation for the English name
Quick Quality Measuring.
The digit 4 means the third series in its development
The third possibility - the use of the QQM4 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.

15. PROPERTIES - optical principle of measuring
QQM system is based on the optical principle by means of an infrared sensor . 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 detect „optical“ defects !

16. PROPERTIES - operation device
QQM 4 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.

17. PROPERTIES - quickness and instant reaction
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.

18. PROPERTIES - portability
The QQM4 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 system

19. PROPERTIES - universality
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.
Universality consists in independence of colour, rough and type of yarn.

20. PROPERTIES - modularity
QQM system has 4 types of measuring
( only ONE hardware with software modules )
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

21. INDICATION
measuring 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

22. INDICATION

23. MEASURING
measuring 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

24. MEASURING

25. ANALYSIS
measuring time about 3-15 min
same as measuring module, but included moreover spectral analysis (must be
measurem min. 100-300 meters of yarn !)
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

26. ANALYSIS

27. DATA SOURCE
measuring time about 1-15 min
(depending on measured length and delivery speed)
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, ...)

28. SW QQM for PC
The delivery also includes a software for a PC (with OS Windows XP).
SW allows measured data to archive, edit, back up, … .

29. SW QQM pro PC
After data transfer from the terminal PSION to the PC
their further analysis, printing results, … is possible.

30. Open the way to
Total Production Maintenance !!!
QQM 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.
Usually, if this tendency is already discovered, you have
time to decide about the maintenance action without
immediate break of spinning process.

31. What can you win with
QQM system ???
- claim decrease
- stabile quality
- higher mills capability utilization rate
- decrease in needs of replacement parts
- maintenance capacity saving

32. Manage your spinning
process and yarn quality!
