          TRAINING REPORT ON RIETER RSB D-30

SALIENT FEATURES OF RSB D-30 :

1.HIGH SPEED : BY a)SCANNING ROLLERS INDEPENDENT OF

                       DELIVERY SPEED.

                     b)PRESSURE SLIVER COILING

                     c)FLAT BELT DRIVING SYSTEM

2.HIGHER EFF%: BY   a)QUICK TOP ROLL RELEASE

                     b)BETTER LAPPING PREVENTION

                     c)PNEUMATIC WEB GUIDING

                     d)AUTO FILTER CLEANING

                     e)EASY ACCSESABILITY

                     f)LESS DOWN TIME FOR CLEANING AND

                       MAINTENANCE

                     g)CENTRAL ROLLER SETTINGS

3)LESS MAN POWER: BY a)CENTRAL LUBRICATION SYSTEM

                     b)AUTO FILTER CLEANING                   

THE MAIN FUNCTION OF DRAWFRAMES ARE TO :

                    1)TO DOUBLE THE SLIVERS FOR UNIFORMITY

                    2)TO BLEND THE MATERIAL

                    3)TO DRAFT THE MATERIAL

                    4)TO PARALLEL THE FIBERES FROM HOOKS

                    5)TO LEVEL THE SLIVERS EITHER FROM CARD

                      OR THE COMBER

CONCEPT OF AUTOLEVELLER DRAW FRAMES :

DRAW FRAMES ARE CONTRIBUTING NOT MORE THAN 5% OF THE YARN MANUFACTURING COST BUT THIS IS THE FIRST M/C IN THE PROCESS

WHICH WILL BE HAVING A POSITIVE CONTROL OF YARN.

                                                   

WITH THE OLD SYSTEMS OF DRAWFRAMES WHERE NO AUTOLEVELLERS ARE PROVIDED THE YARN QUALITY WITH RESPECT TO CV% OF LESS THAN 1.2 CAN BE ACHIVED BUT THE RESULTS ARE NOT CONSISTENT.

TO HAVE A CONSISTENCY IN THE YARN RESULTS THE AUTOLEVERLLER DRAW FRAMES HAVE BEEN INTRODUCED WHERE NO GEAR SYSTEMS ARE AVAILABLE TO ALTER THE YARN RESULTS.

SO,USTER CAME OUT WITH FIRST CAPACITANCE PRINCIPLE OF LEVELLING.AS IT HAD SOME DRAW BACKS T & G SYSTEM CAME INTO EXISTANCE WHICH GOT SUCCEDED.

RIETER ADOPTS THE OPEN LOOP SYSTEM OF AUTOLEVELLING IN THE RSB D-30 DRAW FRAMES.

OPEN LOOP SYSTEM : IN OPEN LOOP SYSTEM THE FEED MATERIAL IS

                   PASSED BETWEEN THE T & G ROLLERS THE

                   DEVIATION IN MASS IS MEASURED BY THE

                   DEFLECTIONS OF T & G THEN TRANSFORMED

                   TO ALTER THE DELIVERY SPEED TO CORRECT

                   THE MASS VARIATIONS.

THE ACTUAL DIFFERENCE BETWEEN THE ORDINARY DRAW FRAMES AND THE AUTOLEVELLER DRAW FRAMES IS THAT THE DELIVER ROLLER DRIVE IS SEPERATED FROM THE ACTUAL DRIVE SO THAT WITH THE ABOVE SAID “OPEN LOOP” SYSTEM IS ACTUATED TO ALTER THE DELIVERY ROLLER SPEED TO CORRECT THE MASS VARIATIONS.

RSB D-30 AUTOLEVELLING :

THE AUTO LEVELLER RSB D-30 DRAW FRAME IS EQUIPPED WITH AN ELECTRONIC LEVELLING SYSTEM.

ALL SLIVERS FED TO THE M/C PASS THROUGH A PAIR OF SCANNING ROLLERS.ONE OF THE TWO ROLLERS IS MOVABLE ACCORDING TO THE VARIATION IN SLIVER CROSS SECTION.

THESE MOVEMENTS ARE YTRANSFORMED INTO VOLTAGES BY A SIGNAL CONVERTER AND FORWARDED TO AN ELECTRONIC LEVELLING PROCESSOR D90.

THE LEVELLING PROCESSOR D90 CALICULATES THE CORRECT TARGET VALUES FOR THE SERVO DRIVE USING :

-          ELECTRICAL SIGNAL VALUES,ARRIVED BY THE SLIVERS FED

-          AND DELIVERY SPEED OF THE M/C.

THE SERVO DRIVE RUNS THE PLANETARY GEARING WITH THE TARGET SPEED.

IN D-30 THE DELIVERY SPEED REMAINS CONSTANT.THE 2^nd ROLLER

DRIVE WILL GET SPLIT FROM THE FRONT ROLL UPTO CREEL DRIVE  TO CORRECT THE MASS VARATIONS.

THE SECOND ROLL SPEED IS INCREASED OR DECREASED BY DIFFERENTAIL GEAR BOX THRU A DC SERVO MOTOR TO ADJUST THE VALUES OF MASS VARIATIONS.

IN D-30 THE MAIN ZONE DRAFT IS ALTERED TO CORRECT THE REQUIRED CORRECTION.THE CORRECTION POINT IS KEPT TOO CLOSE TO THE TOP ROLLER LOADING POINT SO THAT THE SMALLEST FIBER IS ALSO UNDER CONTROL.

SO,WITH D-30S PRINCIPLE OF AUTOLEVELLING SLIVER MASS IS MEASURED AT IN FEED AND CORRECTED WITHIN THE DRAFTING ZONE WITHOUT ALTERING THE DELIVERY ROLL SPEED TO CONTROL THE VARIATION LESS THAN 2.5%.

MACHINE DATA :

SLIVER CREEL :

THE CREEL CONSISTS OF 6 OR 8 CANS :

                 -DIAMETER UP TO 1000 MM (APPROX 40”)

THE SUCTION AIR IS CLEANED BY PASSING THROUGH A FILTER SCREEN AND IS RETURNED INTO DUCT OF CENTRAL AIR CONDITIONING SYSTEM.

EXHAUST AIR VOLUME      : 600 TO 700 CFM

SUCTION UNDER PRESSURE  : 12 TO 15 Mbar

SLIVER GUIDES ABD SLIVER GUIDE BARS :

SLIVER GUIDES AND SLIVER GUIDE BARS ARE PROVIDED BEFOR THE DRAFTING SYSTEM TO ENSURE THE SLIVER PATH TO THE DRAFTING SYSTEM WITH OUT SLIVER DISTRUBANCE FROM THE SCANNING ROLLERS TO THE DRAFTING SYSTEM.

THESE GUIDES AND BARS ENSURES THE SLIVERS ENTER INTO THE DRAFTING SYSTEM : IN THE CENTER

                  UNIFORMLY NEXT TO EACH OTHER

                  WITHOUT GAPS BETWEEN SLIVERS

                  NO SLIVER CROSSINGS

                  SLIVERS WITHOUT BEING TWISTED

BREAK DRAFT AND MAIN DRAFT :

BREAK DRAFT IN RSB D-30 IS VV AND MAIN DRAFT IS KNOWN AS HV

AND TOTAL DRAFT IS V

V  = TOTAL DRAFT

VV = BREAK DRAFT

HV = MAIN DRAFT

V   = VV X HV

HV  = V/VV

ANY CHANGES IN THE MAIN DRAFT i.e HV REQUIRES THE CORRESPONDING CORRECTION OF BREAK DRAFT i.e VV.HOWEVER A CHANGE IN VV REQUIRES NO CORRECTION OF HV.

CLOSEST ROLL SETTING FOR SHORT FIBRES :

-BREAK DRAFT ROLL SETTING =36 MM

-MAIN DRAFT ROLL SETTING  =35.5 MM WITH DRAFTING PRESSURE OF 320 N

WIDEST ROLL SETTING :

-MAXIMUM DRAFT SETTING IS APPROXIMATELY 133 MM i.e BREAK DRAFT AND MAIN DRAFT NOT MOR THAN 133 MM.

ANY COMBINATION OF BREAK DRAFT AND MAIN DRAFT ROLL SETTINGS IS POSSIBLE AS LONG AS THE TOTAL DOES NOT EXCFEED 133 MM.

SO MAXIMUN MAIN DRAFT IS 63 MM

   MAXIMUM BREAK DRAFT IS 70 MM

TOP ROLLER RECCOMENDATION :

THE TOP ROLLERS SHOULD BE USED WITH OUT SPIRAL GROOVES THE BEST SELECTION OF TOP ROLLERS FOR GOOD TECHNOLOGICAL RESULTS ARE :

-          DAY WWW 121 (TYPE)

-          COLOUR = BLACK

-          SHORE HARDNESS = 78

THE TOP ROLLERS SHOULD ALWAYS RUN WITH THE CLEANER BARS IN CASE OF COTTON MEDIUM COUNTS TO INCREASE THE LIFE TIME OF THE TOP ROLLER COTS BY REDUCING THE LAPPING AND ALSO TO MAINTAIN THE TEMPERATURE IN THE DRAFTING SYSTEM.

SCANNING ROLLERS :

RECOMMENDED SCANNING ROLLERS SIZE FOR COMBED COTTONS ARE :

-          6.5 MM WIDTH SCANNING ROLLER WITH THE FUNNEL NUMBER  OF 6.5

-          SCRAPPER HEIGHT OF 6.0 MM

-          CLEANER PLATE HEIGHT OF 6.0 MM

THE SCANNING ROLLER PRESSURE IS TO MAINTAINED AT 120 KGS FOR COMBED COTTON COUNTS.

THE REPLACEMENT OF SCANNING ROLLERS OR THE CHANGE IN PRESSURE ON THE SCANNING ROLLERS REQUIRES :

-          A CHECK OF THE MECHANICAL,BASIC SETTING OF CALENDER  

        DISCS AND,

-          IF REQUIRED,THE CALIBRATOION OF CALENDER DISCS.

LEVELLING CALIBRATION AND SETTINGS :

LEVELLING PRINCIPLE :

THE AUTOLEVELLER DRAW FRAME RSB D-30 IS EQUIPPED WITH AN ELECTRONIC AUTOLEVELLING SYSTEM.ALL SLIVERS FED TO THE M/C PASS THROUGH SCANNING ROLLERS.

AS SAID,ONE OF THE TWO SCANNING ROLLERS IS MOVEABLE.THE VARIATIONS IN THE SLIVER MASS OF THE INCOMING SLIVERS DISPLACE THE SCANNING ROLLER ACCORDINGLY.

THESE MOVEMENTS ARE TRANSFORMED INTO VOLTAGES BY A SIGNAL CONVERTOR AND FORWADED TO AN ELECTRONIC LEVELLING PROCESSOR D90.

THE LEVELLING PROCESSOR D90 HAS THE TASK TO FURNISH THE CORRECT TARGET VALUE TO THE SERVO DRIVE –SERVO DRIVE MOTOR M90 AND SERVO LEVELLER G90(SERVO AMPLIFIER) :-

-ELECTRONIC SIGNAL VALUES,ARRIVED AT BY THE SLIVERS FED,AND

-DELIVERY SPEED OF THE M/C.

SERVO DRIVE TAKES THE INFORMATION AND CONVERTS IT INTO THE CORRECT RPM FOR THE PLANETARY GEARING(DIFFERNTIAL).

THE PLANETARY GEARING WITH ITS CONTROLLED OUTPUT SPEED DRIVES THE MIDDLE AND BACK ROLL-SLIVER ENTRY OF THE DRAFTING SYSTEM.

THEREBY THE REQUIRED DRAFT CHANGE IN THE MAIN DRAFTING ZONE IS ACCOMPLISHED AND THE VARIATIONS IN THE MASS ARE LEVELED OUT.

THE SPEED OF THE DELIVERY ROLL REMAINS CONSTAN- DIRECTLY DEPENDING UPON (CONSTANT)GEAR RATIO OF THE DELIVERY SPEED-WHICH ENSURES EXACT AND CALCULABLE PRODUCTION RATES.

LEVELLING SCHEMATIC :

SCANNING ROLLER CALIBRATION PROCEDURE :

THE FOLLOWING ARE THE STEPS INVOLVED IN THE CALIBRATION OF SCANNING ROLLERS :

a)  SERVO DRIVE CALIBRATION

b)  BASIC SETTING FOR DISTANCE MEASURING SYSTEM

c)  SCANNING ROLLS CALIBRATION

a)SERVO DRIVE CALIBRATION :

THE FIRST STEP IN CALIBRATING THE ELECTRONIC AUTOLEVELLING SYSTEM IS THE CALIBRATION OF SERVO DRIVE.

THE AIM OF CALIBRATING THE SERVO DRIVE IS THE MOTOR SHOULD STAND STILL IN CASE OF NO MASS VARIATIONS IN BETWEEN THE SCANNING ROLLERS.

TO CALIBRATE THE ABOVE PUSH SCANNING ROLLERS AGAINST EACH OTHER MANUALLY AND HOLD THE SCANNING ROLLERS IN THIS POSITION THEN APPLY PRESSURE TO THE SCANNING ROLLERS BY PUSHING THE BUTTON S16.

THEN START THE M/C AND ENTER INTO THE CALIBRATION MENU AND PRESS YES  IN THE MENU NO.72.2.ALL THIS CALIBRATION IS CARRIED OUT AT –25% ERROR.

BOTH THE TARGETED VOLTAGE AND THE EXISTING VOLTAGES ARE DISPLAYED.TO MATCH THE TARGET VOLTAGE AND THE EXISTING VOLTAGE ADJUST THE POTENTIOMETER IN “TACHO” LOCATED IN SERVO LEVELLER G90 TO MATCH BOTH THE VALUES.

THEN GIVE “YES” TO CALIBRATE THE SERVO DRIVE AT +25%.THEN START THE SAME PROCEDURE AS ABOVE.

IN ADJUSTING SERVO DRIVE AT BOTH +25% AND –25% THE DEVIATIONS TO THE TARGET VOLTAGE AND THE ACTUAL VOLTAGES THE TOLERANCE CAN BE + OR – 1 TO 3 VOLTS.

SERVO DRIVE CALIBRATION IS PERFORMED IN THE KEY POSITION IN THE OPERATING INTERFACE PANNEL IN THE  “SERVICE” MODE.AFTER CALIBRATING TURN THE KEY TO “RUN” MODE.

b)BASIC SETTING FOR DISTANCE MEASURING :

RIETER SUPPLIES GAUGES FOR CALIBRATION LEVELLING FOR EXACT SETTINGS IN CALIBRATION PROCEDURES.THE SET OF 5 DISTANCE GAUGES WITH THE FOLLOWING WIDTHS ARE TO BE USED AT THE TIME OF

CALIBRATION – 3MM,4MM(2 PIECES),5MM,6MM.

TO START THE CALIBRATION OF BASIC SETTING FOR DISTANCE MEASURING BYPASS THE LIMIT SWITCHES AT TURN KEY S17 AND OPEN THE LEFT HOOD.

THE CLEARENCE BETWEEN TARGET PLATE AND THE DISTANCE SENSOR B90 MUST BE 4MM.THE SETTING GUAGE SUPPLIED BY RIETER SHOULD BE PLACED BETWEEN THE TARGET PLATE AND THE DISTANCE MEASURING SENSOR B90.

THE 4 MM DISTANCE GAUGE MUST FIT SNUGGLY BETWEEN TARGET PLATE AND DISTANCE MEASURING SENSOR B90.

IF IT IS NOT SO THE DISTANCE IS ADJUSTED MECHANICALLY WITH THE LOCK NUT.

SCANNING ROLLERS CALIBRATION :

WHILE M/C IS STOPPED AND WITHOUT MATERIAL AND ENTER THE “OFF” IN DATA DISPLAY “20.1” AND IT MUST BE SAVED.

THEN THE KEY SWITCH IN OPERATING INTERFACE PANNEL TO “SERVICE” MODE.THE GO TO MENU 72.5 i.e CALIBRATION LEVELLING AND GIVE “YES” ENTER.

THEN SCANNING ROLLER VOLTAGE APPEARS.RELEASE PRESSURE ON SCANNING ROLLERS WITH HELP OF PUSH BUTTON S 16.

PLACE 3MM DISTANCE GAUGE BETWEEN THE SCANNING ROLLERS.PUSH SCANNING ROLLERS MANUALLY TOWARDS EACH OTHER AND THEN APPLY PRESSURE WITH PUSH BUTTON S16.

THE ACTUAL VALUE IS NOW DISPLAYED AT “SCANNING ROLLERS CURRENT LEVELLING”

CONFIRM 3MM BY PUSHING THE ENTER KEY.

PUSHING THE ENTER KEY DELETES THE SAVED MEASURED VALUE DISPLAYED NEXT TO “VALUE” AND REPLACES THE DELETED VALUE WITH THE ACTUAL MEASURED VALUE DISPLAYED NEXT TO “SCANNING ROLLER CURRENT LEVELLING”.

THE SAME HAS TO PERFORMED WITH REMAINING DISTANCE SETTING GAUGES i.e 4MM/5MM/6MM.

THE VOLTAGES FOR THE DISTANCE SETTINGS GAUGES SHOULD BE :

-          3MM = 3300 MV (MILLI VOLTS)

-          4MM = 5000 MV

-          5MM = 6700 MV

-          6MM = 8400 MV

THE ABOVE SAID VOLTAGES OF DISTANCE MEASURING SYSTEM B90 ARE ADJUSTED IN THE POTENTIOMETERS R7 AND R9 TO MATCH THE ACTUAL VALUES WITH THE TARGET VALUES WITH A TOLERENCE OF + OR – 3MV.

AFTER PERFORMING THE ABOVE CALIBRATIONS RED LED IN D90 C-2 SHOULD GLOW OFF.IF IT IS GLOWING THE CALIBRATION IS OUT OF ORDER.THE M/C CANNOT BE PUT ON.

THE  CALIBRATION IS TO BE PERFORMED AGAIN.

RIETER QUALITY MONITER :

CALIBRATION OF RIETER QUALITY MONITER :

PRIOR TO THE DELIVER OF THE M/C THE RIETER QUALITY MONITER IS THROUGHLY CHECKED AND ADJUSTED ACCORDING TO THE STANDARD PROCEDURES AT RIETER.

IN THE EVNT OF ANY PROBLEM ONLY THE RIETER QUALITY MONITE IS TO BE CALIBRATED BY A TRAINED PERSON.

THE RIETER QUALITY MONITER IS TO BE ADJUSTED ONLY IN THE FOLLOWING CASES:

-IF B90 IS REPLACED

-CALENDER DISCS ARE REPLACED

-CHANGING OF CALLENDER DISC PRESSURE

-RQM D50 BOARD IS REPLACED

RQM IS OTHERWISE CALIBRATED ONCE IN A YEAR.

PROCEDURE :

THE RIETER SETTING GAUGES FOR MEASURING THE DISTANCE SENSOR B50 ARE 0.15MM/0.3MM/0.6MM/0.9MM/1.2MM.

BASIC ADJUSTMENT IS BY INSERTING 0.4MM SETTING GAUGE BETWEEN THE B50 MEASURING SENSOR ANS THE TARGET PLATE.IF THE SETTING FOUND OK THEN PROCEED FURTHER WITH THE CALIBRATION WITH THE REMAINING SETTING GAUGES OR ELSE ADJUST THE POSITION OF SENSOR UNTILL THE CLEARENCE BETWEEN TARGET PLATE AND SENSOR IS 0.4MM.

THEM IN THE TEST MENU 73 START THE CALIBRATION IN REFERENCE TO DISTANCE GAUGES 0.3MM/0.6MM/0.9MM/1.2MM.

TO PERFORM THE ABOVE RELEASE THE PRESSURE ON THE CALLENDER ROLLERS AND THEN INSERT THE GAUGE OF 0.3 MM FIRST AND APPLY PRESSURE ON THE CALLENDER ROLLER GENTLY BY TURNING THE LEVER.

THE ACTUAL MEASURED VALUES OF THE VOLTAGES ARE DISPLAYED AT

“SCANNING ROLLER CURRENT RQ-MONITER”.

CONFIRM THE VALUES BY PUSHING ENTER.

THEN PROCEED THE SAME WITH THE REMAINING SETTING GAUGES OF

0.6MM/0.9MM/1.2MM IN THE SAME MANNER.

THE VOLTAGES OF THE MEASURED VALUES ARE ADJUSTED TO THE TARGET VOLTAGES AS PRESCRIBED BY THE RIETER.

THE ADJUSTMENTS ARE MADE IN THE POTENTIOMETERS R7 AND R9 OF B50.

THE FOLLOWING ARE THE VOLTAGES WHICH ARE TO BE MATCHED WITH THE MEASURED VOLTAGES AT EACH DESTANCE MEASURING GAUGE:

-0.3 = 1885 MV

-0.6 = 3220 MV

-0.9 = 4555 MV

-1.2 = 5890 MV

AFTER ADJUSTING THE ABOVE SAID TARGET VOTAGES TO MATCH WITH THE MEASURED VOLTAGES THE CALIBRATIONS ARE TO BE ENTERED FOR SAVING WITH THE ENTER KEY.

AFTER PERFORMING THE ABOVE CALIBRATIONS RED LED IN D50 C-2 SHOULD GLOW OFF.IF IT IS GLOWING THE CALIBRATION IS OUT OF ORDER.THE M/C CANNOT BE PUT ON.

THE  CALIBRATION IS TO BE PERFORMED AGAIN.

IMPORTANT INSTRUCTIONS TO BE FOLLOWED DURING CALIBRATIONS:

1.CALIBRATION TO BE PERFORMED WITH THE INSTRUCTION MANUAL

2.ONLY RIETER SETTING GAUGES ARE TO BE USED

3.THE CALIBRATIONS TO BE PERFORMED BY TRAINED PERSONS

4.SCANNING ROLLERS PRESSURE TO BE GIVEN FIRST BY MOVING WITH HAND AND THEN WITH THE S16 PUSH BUTTON.

5.PROPER TOOLS RECCOMENDED BY RIETER ARE TO BE STRICTLY USED
