PRINCIPAL OF BALE PLUCKER


OPERATIONAL PRINCIPLE OF BALE PLUCKER
 
The UNI-flock(BALE PLUCKER)  processes cotton from all sources and man made fibers in staple lengths of up to 65 mm. The bales being opened are placed lengthwise or crosswise on both sides of the bale opener, and the take-off unit can process up to four different assortments.
Reduction of the raw material into micro-tufts is assured by the patented double teeth on the take-off roller and the grid with closely set clamping rails. The unique geometry of the double teeth ensures the uniform treatment of the entire bale surface. Retaining rollers traveling with the take-off unit prevent bale layers from sloughing and ensure precise, controlled operation over the entire height of the bale. The UNI-flock (BALE PLUCKER) still produces small tufts, even at maximum output of 1400 kg/h.
The take-off unit is lowered by a preselected or computed distance at each pass. Running-in and running-out programs compensate for the differing hardness of the bales over their cross section and ensure a uniform level of production. The fan incorporated in the swiveling tower extracts the opened tufts and feeds them into the tuft channel running between the guide rails. Transport to the following machine is pneumatic.

· DISTINGUISHING FEATURES OF UNI-FLOCK(BALE PLUCKER)

The UNI-flock(BALE PLUCKER) is basically one type of opening which is most commonly utilized in place of “hopper bale openers”. The distinguishing features of UNI-flock (BALE PLUCKER) are:

1. Bale opening into micro-tufts for effective cleaning and dust extraction.

Micro tufts are the basic requirement for the production of yarn quality. Trash and dust can only be removed from natural fibers gently and efficiently on the surface of the tufts.
The take-off unit of the UNI-flock(BALE PLUCKER) is considered to be the “heart” of the system as it is responsible for micro tuft formation. The patented take-off roller and the grid design with small gaps between the clamping rails enables small fiber tufts ( micro tufts ) to be extracted. The twin-tooth profile ensures uniform, gentle and efficient extraction of the tufts, also irrespective of the take-off roller’s direction of rotation.



2. Uniform take-off of bale lay-down by means of “BALE PROFILING”

Bale Profiling guarantees totally uniform bale take-off. The height profile of the bale lay-down is precisely detected by light barriers and memorized. Scanning is performed at a constant speed of 9 m/min. Tufts are already taken off in the profiling phase. Continuous feeding of the subsequent machines is thus ensured from the outset.

During the subsequent passes the bales are opened at the preselected speed of travel and take-off depth. In the process the system automatically compensates for differences in height in the bale profile. Lab our-intensive manual leveling is eliminated. After the required height range, take-off depth and speed of travel have been entered for each group of bales, take-off proceeds fully automatically.

3. Simultaneous processing of up to 4 assortment

We can lay down bales in 4 groups on each side of the machine. This means that four assortments can be processed automatically at the preselected take-off speed and with the required production volume.


4. Patented, individually interchangeable double teeth on the opening roller

The double teeth enable maintenance intervals to be halved. The teeth are mounted individually. They can easily and quickly be replaced if required, without removing the take-off roller. This explains the exceptionally high operational readiness of the Uni-flock (BALE PLUCKER)

5. Processing of cotton from all sources and man-made fibers in staple lengths of up to 65 mm
  
6. Bale lay-down over a length of 7.2 to 47.2 meters

A bale lay-down of overall lengths of 7.2 to 47.2 meters and two take-off of unit lengths of 1700 mm and 2300 mm. The maximum version is capable of accommodating raw material up to 40 000 kg. This ensures flexible, economical and largely autonomous processing on UNI-flock(BALE PLUCKER).

7. Take-off width select-able between 1 700 mm and 2 300 mm

WINDING CLASSIMAT FAULTS

Image
There are two types of yarn faults, Frequently occurring faults and Seldom-occurring faults. 1.     Frequently occurring faults : This  type of faults includes  thin, thick and neps as measured by evenness tester. These faults occur in the range of 10 to 5000 times per 1000 meters 2.     Seldom occurring faults : Theses faults refer to the thin places and thick places in the yarn, which are so seldom occurring for atleast 100 km of the yarn. The seldom occurring faults can be grouped in three main types Short thick, Long thick and Long thin faults. Classifications of  faults : This will provides a detailed break-up of yarn faults based on the length and dimensions of the faults. There are totally 23 types of faults, each fault is identified by an alphabet and a number. The alphabet ‘A’ to ‘G’ indicates the thick yarn faults while the letters ‘H’ and ‘I’ represent thin faults. The Number 1 represents a faults of size +100 t...

CLASSIFICATION OF YARN FAULTS

Assessment of Classimat faults  in classimat tester : Due to the existence of fewer faults and nature of distribution of these faults, it is recommended to take randomly at least 5 tests of each 100km of yarn. The testing yarn has to be carried out on a winder having a uniform winding speed. Once the testing is over, the results are in the form of printout. And it contains two sets of data, the one is Individual faults & other one is cumulative faults / 100km of yarn. And the major causes of the Classimat faults are tabulated below : SHORT THICK FAULTS :            A4 -High Ring frame speed -Loose (or) Spun in fly -Foreign matter -Type of spacers          B4 -High Ring frame speed -Loose (or) Spun fly -Floating fibers -Narrow cage length and tight cage length              ...
