LK 54 COMBER TIPS

LK 54  COMBER

POINTS TO BE TAKEN CARE

A.    Running-in, the comber should be start with 250NPM, First oil change is done at 24 hours of running and the speed has to be increased to 300 NPM. After 300 working Hrs the speed has to be increased to 350 NPM. The second oil change to be done at 500 working hours and the speed can be increased to 375 NPM. In every oil change, all the fastener to be checked for tightness.

B.     The machine attendees have to clean the following areas with the given internals with fly gun or brush. 

1.   DRAFTING AREA               -                                              4 HOURS

2.  COILER AREA                     -                                       4 HOURS

3.  TOP COMB cleaning (after every new lap is fed) -         2 HOURS

4.  MACHINE BACK & FRONT & NIPPER ASSLY

      (REMOVE THE COVER AND CLEAN)                    -      8 HOURS

5. DETATCHING AREA BELOW THE CURVED PLATE -    24   HOURS

C.     Care should be taken while fixing the web guide in between bottom detaching roller otherwise it will damage the detaching roller.

D.    -400 Pascal should be maintained above/below the machine in noil duct. In case of continuous suction system, - 100 Pascal has to be maintained at the exhaust air trench below the suction box. This will help the comber Cleanliness.

E.     An electrical inter link should be provided with the waste collection system and comber machine whenever the compactor is stopped the machine will be stopped and also a bulb indication at the hall will help the tender to know the waste collection system is stopped/running.

F.     The coiler calendar roller gap should be maintained at 0.2mm and the pressure may vary from 2 to 3 bars. This gap should be checked once in a month in general cleaning.

A.    In general cleaning the detaching bottom roller striper spring action to ensured and corrected by cleaning the fluff accumulated.

B.     Don’t clean the table bottom area while machine is running. Clean the machine while the machine is stopped.

C.     Use Liters to measure the oil to be poured in the head stock, this will avoid the excess oil being poured and resulting in the spilling of the same in the floor.

D.    Table stop motion to be checked in every 15 days, this has to be checked at the 3^rd & 4^th heads and 5^th &6^th heads particularly. If necessary it has to be corrected by aligning the table stop motion photo sensors.

E.     Brush height gauge has to checked and corrected once in 2 months.

F.     For further clarification please refer Instruction manual.

LH 10 LAPFORMER TIPS

Textile Machinery Division For the better performance of combing system. LAP FORMER LH10 POINTS TO BE TAKEN CARE A.    In lap former, the piecing of the broken sliver at creel has to be brought up to the console table and inserted in the adjacent sliver to avoid any jamming taking place at calendar roller area and to avoid the loose sliver sucked by the suction points. B.     Once in four hours, drafting top roller, pneumafil box has to be cleaned. C.     Once in eight hours, top cover has to be removed and calendar roller zone to be cleaned. D.    Main calendar roller stripper to be cleaned every shift, shift jobber should be provided with the machine door key to assist the machine tender for the stripper cleaning. E.     Instruction has been given in Tamil/Hindi for workers to take manual doff in case of power fail. F.     Reserve trolley should be connected to the previous trolley in the last doff only.  The completed trolley should be removed immediately after the trolley is filled with laps. That is only one trolley will be always in contact with the machine. This will avoid break down at trolley indexing area. G.     During placing the trolley in the lap former the spool has to be checked and ensured whether the spool is placed properly. This will avoid the doff sequence struck up. H.    Regarding maintenance, Oil lubricator to be checked periodically once in 15 days.  If oil is less should be filled with servo system 32, While filling main in coming air to be closed, machine air  shut of valve to be shut off and the air in the regulator to be released, Then only the oil pot to be removed and filled with oil otherwise oil pot will break. Textile Machinery Division CONTINUATION SHEETS A.    Once in 3 days all the calendar rollers to be cleaned with petrol by rotating the calendar roller, striper of the calendar roller also to be removed.  Cleaned and fixed again properly this will avoid and calendar roller jam problem and subsequent break down. B.     Doff test to be carried out completely for two times for all the steps in the doff test and if necessary adjustment to be made to flow control valves. This has to be carried in every general cleaning schedule. This should be performed by mills comber fitter only. C.     The main calendar roller earthing plate gap to be ensured 2mm in every cleaning by maintenance fitter. D.    All Chain alignments to be checked every general cleaning. E.     For further clarification please refer Instruction manual. F.     The entire Lap former breaker LDO/6 draw frame should be fed by the randomized card cans. The delivery cans of the LDO/6 draw frames should be number and should be feed as mentioned below. G.    The creel feed cans to be arranged in randomized, which are RHS & LHS sides of the draw frame should be placed as mention below.          Creel 1                                               Creel 2          R        L                                              L        R          L        R                                              R        L          R        L                                              L        R                 L        R                                              R        L          R        L                                              L        R          L        R                                              R        L F : The default screen shows the following.

CONFIGURE FOR EEPROM PROGRAMME UPLOADING Reports Current shift and last 6 shift detail will be recorded, cumulative run time and indle time can also be noticed. Alarm histry can be viewed for type of stopage and the time of stopage. Doff test. Details of the steps given in text sheet, to perform doff test the lap doff mode has to be changed from auto to manual. Service. Date & Time Change This will go to the initializing menu which requires 3rd level password. All the shift previous shift datas will be erased if we perform. We can change the shift time and date. Password change. Requires 3rd level password, can change all 3 levels of password. MASTER reset. This will be performed in extreme condition,if there is no other means.It will bring back all pneumatic cylinders back tohome position, but all the datas will be erased we have reenter all the data including process,machine parameter and date & time. Trouble Shooting. This will be helpful for electrical technecians to find out the fault in the electrovalve, sensors and push buttons
