Introduction

Industrial robots

Applications in textile industry

Importance of robots

Impact of robotics

Advantage & Disadvantage

Conclusion

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

Productivity :-The effectiveness with which resources are consumed.

Efficiency:- Doing things rightly.

To achieve this, we need adaptive manipulation systems having some…………

“ARTIFICIAL INTELLIGENCE”

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.

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.

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.

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.

Applications of robotics in textile

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”.

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.

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.

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.

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.

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.

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.

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.

An individual skilled operator may achieve areasonable degree of accuracy but measurements varyfrom 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 diffusesensors . The digital status of each sensor iscommunicated to robot controller through DI (digitalinput) ports. A fabric sample is aligned parallel to anedge or a clamping device through a series oftranslations and rotations.

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.

A bending test has beenimplemented using a cantilevermethod.

This test requires fabricmanipulation in a horizontalplane, compared to a purebending test which needspositioning of the sample in avertical plane. The fabricsample is drooped continuouslyas a cantilever and the fabricedge is detected by a bendingangle sensor.

Integration of human and technical resources.

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.

Robot are more costlier.

Experts are required to maintain them.

Threat to employment in population crowed country

like india.

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.
