New Features in Excello Automatic Cone Winder |
|
The following new features certainly help
to produce high quality packages with higher
productivity and less maintenance. And this latest
developments and features can be retrofitted in old
machines from the year 1997 onwards to make it as a new
generation winder. |
|
|
1. 9-Can Bobbin Magazine System: |
|
|
|
9-Can bobbin magazine system holds 60% more reserve
bobbins and thereby it takes 60% more time to exhaust
because 9-Can bobbin magazine system has 8 reserve
bobbins whereas 6-Can bobbin magazine system has only 5
reserve bobbins.
The 9-Can bobbin magazine system reduces the frequency
of bobbin loading and results in significant reduction
of operator’s walking distance.
More no. of spindles can be loaded by an operator in
comparison with 6-Can bobbin magazine system thereby
significant reduction in operators. |

2.
Square
Type Unwinding Accelerator: |
|
|
|
Prior to this square type unwinding
accelerator, an open type unwinding accelerator was
used. It was not effective to control the balloon
resulted more hairiness due to higher balloon diameter.
The recently introduced square shaped unwinding
accelerator is specially designed to control the balloon
diameter in order to reduce the unwinding tension. |

3. Heavy Duty Sintered Scissors: |
|
|
|
Newly
introduced sintered scissors are made with a special
material by powder metallurgy technique. These scissors
never requires lubrication or mechanical maintenance.
And also the life of the sintered scissors are longer.
|
|
 |
|
|
|
|
|
4. Reduced Doffing Time: |
|
|
|
The cycling time of automatic doffer is reduced from 20
seconds to 15 seconds. 25 % decrease in the doffing
time results in increase the productivity little bit.
|
|
|
|
|
|
5. Increased Tail End during Doffing: |
|
|
|
The Excello Doffer provides an adjustable Tail End
length from 0.9m to a maximum of 2.5m. This increases
the efficiency in knitting and Loom-shed as Tail End
Missing is eliminated. |
|
 |
|
|
|
|
|
6. Surge Protection: |
|
|
|
Surges are transient voltages or currents that exceed
the electrical limits of a system or equipment. Surges
cause extensive damage to Electronic and Electrical
parts and in some situations momentary malfunctioning of
equipment.
This kind of failure was sometimes occurring in our
Headstock Electronics and frequent occurrence of 220V
Electronics Alarm.
Surge Suppressors are provided at the Electrical Panel.
This has improved the reliability of Headstock
Electronics and has eliminated the occurrence of 220V
Electronics Alarm due to Surges.

Suction Motor Independent ON / OFF: |
|
|
|
In
automatic cone winders, the hard waste should be removed
often from hard waste collection bin. The entire
machine should be switched off while removing hard waste
due to precautionary measures. An independent switch is
currently installed for suction motor to switch off
independently.
Currently,
one can collect the waste by stopping suction motor
instead of the entire machine. The spindles are not in
splice cycle will function as usual. This results
significant improvement in machine efficiency and
productivity as well as there is zero machine down time. |

8. Drum ON/OFF System: |
|
|
|
Patterning
occurs whenever the surface speed of the package and the
surface speed of the drum coincide. In the previous
method, modulation unit is provided for giving
oscillation to the cradle continuously through out the
package. In the new development, drum ON-OFF system is
introduced continuously throughout the package for
avoiding the pattern.
Advantages:
-
Better
take-up package and greater precision of yarn length
-
Less
maintenance of parts that move the cradle
-
Less
energy consumed

9. Wax Exhaust Detection: |
|
|
|
A Magnetic
Sensor continuously monitors the Wax Roll. When the Wax
Roll is about to get exhausted, an Alarm Signal flashes
for Wax Roll Change. But the spindle keeps operating.
If the Operator replaces the Wax within 15 minutes, the
Alarm Signal is automatically cancelled.
If Wax is not replaced
even after 15 minutes of Alarm Signal flashing, the
particular spindle will be stopped. |

Inverter Drive for Suction Motor: |
|
|
|
Usually the Suction Level generated
for the reliable holding of the upper is much greater
than the Optimum Level. By installing Closed Loop
Control for the Suction Motor by means of a Sensor and
Inverter, the Optimum Level of Suction depending on the
application can be generated.
The Closed Loop Control
System ensures that the Set Level of Suction is
maintained uniformly even when many spindles are in
splicing process. This Closed Loop Control of suction
leads to considerable savings in Power Cost. |

New
Industrial Computer: |
|
|
|
Feedback
from customers in Rajasthan region indicated that the
LCD (Liquid Crystal Display) of the machine computer
requires frequent replacement. The reported phenomenon
was studied and analysed. The analysis pointed out the
high ambient temperature around 45˚C, present in that
region, for most of the year, as the root cause for the
failure of the LCDs of the computer.
The New
Industrial Computer has a high operating temperature
version LCD for reliable operation. This retrofit can
be done for the existing computers in the field also.

12. Automatic Cone Winder
with Yarn Sensor: |
|
|
|
Usually
the Automatic Cone Winder is equipped with an Electronic
Yarn Clearer for clearing of Yarn Faults. But there are
specific applications where Electronic Yarn Clearing may
not be required. The ACW without Electronic Yarn
Clearer caters to this segment.
-
Cone-to-Cone Rewinding of already cleared yarn
-
Winding of Fancy Slub Yarns
-
Cheese
to Cone Winding of Dyed Yarns
-
Winding of residual yarns from various cones.
The
Electronic Clearer is substituted by an Electronic Yarn
Sensor. Since Fault Clearing is not required, it checks
for presence of yarn only. It gives a signal for yarn
break during winding to enable Automatic Splicing. The
Yarn Sensor used is of Optical Type and hence it can
work with any type of yarn. |
