There are many fields in which automation may be related to electrical,
mechanical lingistres, psychology and philosophy. In our project, IR sensor is used to
detect the components, which is passed in the conveyor and this signal is given to the
control unit.
The control unit is activating the solenoid valve, which is connected to the spray gun
for the particular time period. This time period is varied by the variable resistor.
This is an era of automation where it is broadly defined as replacement of manual
effort by mechanical power in all degrees of automation. The operation remains an
essential part of the system although with changing demands on physical input as the
degree of mechanization is increased.
Degrees of automation are of two types, viz.
Full automation.
Semi automation.
In semi automation a combination of manual effort and mechanical power is required
whereas in full automation human participation is very negligible.
Need For Automation
Automation can be achieved through computers, hydraulics, pneumatics, robotics,
etc., of these sources, pneumatics form an attractive medium for low cost automation.
The main advantages of all pneumatic systems are economy and simplicity. Automation
plays an important role in mass production.
 Low cost intelligent robot
 Portable in size and Easy transportable
 Since the project is based on the sensor, it is compact and swift and response.
 No external devices are used here to control it.
 The medium is air; the operation of the arm movement is fast.
 Nozzle adjustment is done by manually
 This system operated in pneumatics, so we need air tank or compressor
