Present activities
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 ?
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 moiré effect is concerned.
In this case, the greatest problem for the manufacturer is to identify the spinning unit (SU) which produces defective yarn.
The greatest problem for the manufacturer is to identify the spinning unit (SU) which produces the faulty yarn.
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 1 * LABORATORY ANALYSE
Troubleshooting 2 * ON-LINE QUALITY CONTROL
- automatics, no need operating staff - high purchase cost - absent solution for ring spinning machines - stationary - only for ONE machine - requisite of higly qualified and experienced operator for machine operation Troubleshooting 2 * ON-LINE QUALITY CONTROL ADVANTAGES: HANDICAPS:
* QQM-3 system Troubleshooting 3
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.
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
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
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 QQM-3 device enables to carry out a 100% operation control of all SUs 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
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
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 )
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
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
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 meters of yarn !) measuring time about 3-15 min (depending on measured length and delivery speed)
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 Windows95 and newer). SW allows measured data to archive, edit, back up, …. SW QQM-3 for PC
After data transfer from the terminal PSION to the PC their further analysis, printing results, … is possible. SW QQM-3 for PC
* QQM-3 system ADVANTAGES: 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 Troubleshooting 3
Assembly of QQM-3 system Basic part of the QQM-3 system is measuring head , which scan a picture for every 2mm of yarn. By the help of cable  and converter  it can be connected to the terminal PSION . There are scanned data processed and displayed results.This confiration is fully functional. System QQM-3 also included charging unit with additional battery , portable stand and reduction for ring-spinning machines. 1 … measuring head 2 … terminal PSION 3 … charging unit with additional battery 4 … TTL - RS232 converter 5 … RJ-6 cable
Parameters of QQM-3 system Measured Y.C.: Measured speed: Power supply: Battery charging: Type of PC: Connection. to PC: tex m/min Pb accumulator 12 V, 2.3 Ah ( measuring time up to 30 hours ) V, Hz (automatics) IBM compat., OS Windows (Win95 and newer) serial port RS 232 QQM-3 system is designed for standard spinning mill conditions.
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 with QQM-3 system ??? - claim decrease - stabile quality - higher mills capability utilization rate - decrease in needs of replacement parts - maintenance capacity saving
