Field of the invention
The invention particularly relates to textile machinery, particularly to a quality control system in a spinning mill for producing packages via at least one or more of the steps of mixing and blowing, combing, drawing, roving, fine spinning and winding, or via at least one or more of the steps of mixing and blowing, combing, drawing, open end or air jet spinning.
Description of the prior art
Generally, in a spinning mill, yarns are produced via various steps such as mixing and blowing, combining, drawing, roving, fine spinning, rewinding and the like after the reception of raw cotton. In the processing steps, fiber machineries are used exclusively for the respective steps, for example, such as a mixing and blowing machine, a combing machine, a drawing machine, a roving machine, a fine spinning machine, a winder, a doubler, a twisting machine and the like are used. The produced yarn products are shipped in the form of packages from the spinning mill and then delivered to post-steps outside the mill, for example, steps for woven fabrics, dyeing and the like.
However, in the processing steps in the spinning mill, two or more fiber machines may be used in the same step, and one frame often comprises a number of spindles. That is, fibers are repeatedly branched or merged while the fibers are sent from one step to the next. Even in the case where the result of a sample check is judged to be defective, it is difficult to specify the step which is actually in an abnormal condition out of the number of steps that occur between the receptions of raw cotton to shipment. Moreover, it was impossible to specify a machine which is in trouble or defective out of all of the frames or spindles. Therefore, the pursuit of the cause for defectiveness by checking is compelled to the interior of the respective processing step, resulting in the risk that a great quantity of final yarn products of poor quality are produced.
Moreover, in the case where final products are produced overlooking the state where the yarn quality is poor, it is extremely difficult to find that said yarn is poor in quality from the characteristics of yarns. Such discovery is often very delayed such that the poor quality of yarn is found only outside the spinning mill.
From the foregoing, the delivery of products and necessary number of production in the production plan are affected by the conventional way of processing.
Thus the main objective of the present invention is to provide a simpler yarn spinning method which is simpler in use and easy to repeat over large scale.
Brief description of the invention
Yarn spinning “Lotte Suutrchkrm (Dhaga Katai)” method comprising feeding and drafting of roving raw material; twisting; and cop formation. Feeding and drafting of roving of raw material comprises hanging on creel of ring frame with slightly pulling to a roving bobbin into a moveable holder fitted on creel of a ring frame, manual feeding of roving end through a roving guide to a back feed roller, said back feed roller to a second draft roller (middle roller) and main draft (stretch) for the required count between said second and a front roller with a bottom apron and a top cradle apron which is derived by the middle roller. In main drafting, top and bottom apron & spacer is important roll, its help to control the fibre gripping during drafting and also control hairiness of final yarn during spinning process. The top arm comprises three rubber rollers, help to provide the pressure on all three bottom rollers like back feeding roller, middle roller and front roller and without pressure arm the drafting is not possible.

Ring Rail (17) is used to support the rail and platform of Ring holder. Spindle (18) is used to move the bobbin. Jockey pulley (19) to move the spindle with the help of synthetic tape. Spindle Booster (20) is a base of spindle.
In the method for optimizing with regard to quality, productivity a manufacturing process in a textile plant according to the invention,
Yarn spinning comprises three processes in Lotte Suutrchkrm (Dhaga Katai) according to the embodiment of the invention.
1. Feeding and Drafting of Roving
a. Cotton roving raw material
b. Hanging on creel of ring frame with slightly pulling to roving bobbin into moveable holder fitted on creel of ring frame
c. Manual feeding of roving end through roving guide to the back feed roller
d. Back feed roller to 2nd draft roller (middle Roller); there is draft (stretch) around 3-10 % for to reduce the roving weight up to certain limit according to the required count.
e. Main draft (stretch) for the required count between second and front roller comprising bottom apron and a top cradle apron which is derived by the middle roller.
In main drafting, top and bottom apron & Spacer is important roll, its help to control the fiber gripping during drafting and also control hairiness of final yarn during spinning process. The top arm consisting of three rubber rollers, help to provide the pressure on all three bottom rollers like back feeding roller, middle roller and front roller and without pressure arm the drafting is not possible.
2. Twisting – after proper drafting the fibers comes from front roller in loose form & parallel and its need to proper twist for strength of yarn and avoid breakages during spinning. a. Twist to the yarn consisting through moveable spindle which is drive by the main shaft of motor and also through help of lappet hook, ring travellers, steel ring & twist gears.
Twist in yarn consists through the front roller speed and spindle speed. For example for count 35 nm , spindle speed is 8500 rpm and front roller speed 12.7 meters / minute and twist per meter will be 670 ( Twist per inch 17.0 ). Normal > Z twist direction is recommendable in single yarn and some special application > S twist direction also possible with some changes of gear drive. Twisted yarn wound on the tube / bobbin in cop form.
3. Cop formation – Twisted yarn wound on the plastic or paper tube according to the fitting on spindle. Cop formation of yarn on tube with the help of some gear drive, lifting ring rail. Proper cop formation i.e. winding of yarn on bobbin / tube is most important to unwind the yarn with proper speed and to control wastage of required yarn.
Characteristics of the Lotte Suutrchkrm (Dhaga Katai) (Ring Frame)
The Lotte Suutrchkrm (Dhaga Katai) (Ring Frame) has total number of spindle around 16 and number of top arm is having 8. The speed of the spindle is 8000-16000 per minute. Depending upon the count and yarn type the production of the Lotte Suutrchkrm (Dhaga Katai) is 2 Kg to 4 Kg. The yarn count is 10nm to 100nm. And twist as per the requirement.
According to the present invention the Lotte Suutrchkrm (Dhaga Katai) can be run by solar power, electricity, battery or manually. The power consumed by the machine is 0.75 HP.
In another preferred embodiment of the invention, the suction device is used to suck roving waste for high quality yarn.
One more feature of the invention is machine is attached with cone winder. There is no thread breakage during the stoppage of machine at any time. Moreover, due to increase in production there is high earning of operator of machine. And also the machine requires very limited land space. It is estimated that the quality of yarn produce from machine is equal to large spinning units.
