The document discusses the application of robotics in the textile industry. It describes how industrial robots are being used for various tasks like bale handling, yarn splicing, auto cone changing, auto doffing, garment folding and packing, embroidery, fabric testing, and welding. The use of robots improves productivity, reduces costs and cycle times, improves product quality and safety, and increases efficiency. However, robots also have disadvantages like high costs, requirement of experts for maintenance, and potential threats to employment. Overall, robotics is helping to improve various operations in the textile industry.

3. Robotics is a form of industrial automation.
These are machine systems that can be conveniently
directed to change their mode and sequence of
operations by means of software instructions.
These programmable systems requires high level of –
Consistency
Precision
Repeatability
Adaptability

4. Productivity :-The effectiveness with which resources are
consumed.
Efficiency:- Doing things rightly.
To achieve this, we need adaptive manipulation
systems having some…………
“ARTIFICIAL INTELLIGENCE”
5. 1. Actuator - A robot system contains multiple actuators
which are essentially required for full control of position
and orientation.
2.Sensor- To give information regarding the position and
possibility, the velocity of the actuator, to control on it.
3.Computation Objects- It requires a micro-computer to
perform work place analysis, servo, kinematics and
dynamic operations. In addition it should perform
supervisory operations such as path planning and operator
interaction.

6. 1.Mechanical Stop Control Robots
Here an actuator moves a joint until the joint runs up
against a mechanical stop. Programming of such
robots is typically done with a screw driver
although some flexibility may be built in by using
several selectable stops on each axis.

7. 2.Servo Controlled Robots
It is a point to point programming in which the
actuator may be controlled in such a way that it can
stop at any point along its path.
8. 3.Continuous Path Control Robots
Here the robot may be required to interact
continuously with its environment in more complex
work environment.
Some typical examples are welding, spray painting and
performing operations along a moving conveyor.
10. After passing the receiving station each bale will be
moved by the conveyor to a loading station where it
will be picked by robot and taken to storage.
When bale is selected for processing it will be removed
from the ware house by a robot on a” first-in, first-out
basis”.
11. Auto Can Changing:
In carding and draw frame process when a pre fixed
sliver length is filled in can Auto can changer actuated
& rotates the arm by 120 degree then full can is
replaced by empty one without stopping the machine.
12. Yarn splicing at
autoconer:
Each time there is an end
break or bobbin change,
this join the yarn ends
with a splice which is
virtually identical to the
yarn.
13. The strength and elongation values of spliced joined
are almost always comparable (more than 90%) with
those of the yarn itself.
Latest automatic splicer arm act like a robot and it
offers better opening to the yarn ends and a more
favourable overlap in splicing zone.
14. Auto Cone Changer:
It changes a full cone by empty one when the
predetermined length is wound on it & resumes the
winding at lowest starting time automatically.
15. Auto Doffing at ring frame:
It changes a full cop by empty one when the
predetermined length is wound on it & resumes the
ring frame at lowest starting time automatically.

16. In garment industry the garment folding and packing
is carrying out by the robots. They take the garments,
fold it and then pack it.
A new automated sewing system is described,
consisting of two robots handling the fabric on the
table in a similar manner as does a human operator
during sewing.
17. To enable user-friendly
operation of the system
operation, particularly in
the phase of preparing
new tasks, the original
Multi-arm Robot Control
(MRC) system has been
developed.

18. An individual skilled operator may achieve a
reasonable degree of accuracy but measurements vary
from operator to operator.
In the robotic test system, the tests cycles are applied
by the robot in addition to fabric handling.
The fabric edge is detected by the two infrared diffuse
sensors . The digital status of each sensor is
communicated to robot controller through DI (digital
input) ports. A fabric sample is aligned parallel to an
edge or a clamping device through a series of
translations and rotations.
19. A compression test is
conducted by a circular
head attached to the
robot arm the fabric
sample is compressed at
a predetermined strain
rate(typically 0.02mm/s)
until a preset pressure
limit is attained.

20. A bending test has been
implemented using a cantilever
method.
This test requires fabric
manipulation in a horizontal
plane, compared to a pure
bending test which needs
positioning of the sample in a
vertical plane. The fabric
sample is drooped continuously
as a cantilever and the fabric
edge is detected by a bending
angle sensor.

21. With the help of robotics in uster tensorapid high
working speed & accuracy is achieved for measuring of
single yarn strength & elongation.
31. Quick response to market/customer.
Increased capability to consumer requirements.
Increased capability to react to market changes.
A new market segment –customized garments- to
expand
32. Increase in the final product quality(lower risk of
production rejects) and quality standardization.
Intelligent flexible highly re-configurable
manufacturing processes.
Increase in the process efficiency, speed and reliability.
Reduced costs mainly for small batches.
Integration of human and technical resources.
33.
34. Robotics & automation can, in many situations,
increase productivity, safety, efficiency, quality and
consistency of products.
Can work in very critical situation i.e. in hazardous
environment without the need of life support.
It needs no environmental comfort such as lighting ,
air conditioning etc.
Much more accurate than human.
Work consistently , tirelessly.
Speed of operation is fast.
Robot will not ignore the work.
35. Robot are more costlier.
Experts are required to maintain them.
Threat to employment in population crowed country
like india.
36. Robots are being used in textiles today and
substantial developments are already being made.
Since we operate in what may generally be described
as free enterprise economy, the future use of this new
technology will develop as the economics of each area
of manufacturing dictate . No doubt about it , all of us
can look forward to exciting developments in this
field.
