... problems with quality of yarn ?

Such pictures are well-known only to machine operators

and/or to the peoples responsible or for quality control and claims

Such woven fabric quality should not leave the plant.

If such fabric is sold to a customer, then in most cases a claim

can be expected which leads to high financial losses.

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

The greatest problem for the manufacturer

is to identify the spinning unit

which produces the faulty yarn.

Troubleshooting 1

* LABORATORY ANALYSE

Troubleshooting 1

* LABORATORY ANALYSE

ADVANTAGES:

HANDICAPS:

- exactly and detailed results

- high purchase and operation costs

- long time to results necessary

- necessary of attendant operator

- practically impossible for measuring of all SU

Troubleshooting 2

* ON-LINE QUALITY CONTROL

Troubleshooting 2

* ON-LINE QUALITY CONTROL

ADVANTAGES:

HANDICAPS:

- automatics, no need operating staff

- high purchase cost

- absent solution for ring spinning machines

- stationary - only for ONE machine

- requisite of highly qualified and experienced

operator for machine operation

Troubleshooting 3

* QQM4

Troubleshooting 3

* QQM system

ADVANTAGES:

HANDICAPS:

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

- quick mesuring and instant reaction

- conjunction of operational & labor. device

- for several OE rotor and ring spinning machines

- portability - simply portable device

- very low purchase and minimum operation cost

- not fully automated process - necessary

of attendat operator

what is

QQM system ???

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.

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 !

PROPERTIES - optical principle of measuring

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.

PROPERTIES - operation device

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

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

PROPERTIES - portability

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.

PROPERTIES - universality

PROPERTIES - modularity

QQM 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 )

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

INDICATION

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

MEASURING

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

ANALYSIS

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)

The delivery also includes a software for a PC (with OS Windows XP).

SW allows measured data to archive, edit, back up, … .

SW QQM for PC

After data transfer from the terminal PSION to the PC

their further analysis, printing results, … is possible.

SW QQM pro PC

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.

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

Manage your spinning

process and yarn quality!
