Project Definition/Description
Theme of the project deals with simplified approach to develop an automated
system for filling and capping.
Automated system for filling and capping is operated through Programmable
Logic Control using ladder logic
Containers are confined in position over a conveyor and conveyor is driven
by 24volts DC geared motor.
Containers are sensed by capacitive sensor and issue a command to PLC to
stop the conveyor at predefined position and filling process is started.
Inductive sensor determine the quantity of material filled in the container and
the container is directed for capping process.
Capping process is done by the help of handling device.

Handling device is equipped with 3 axis.
Two linear axis and one rotating axis.
Lifting is done by a double acting Pneumatic
cylinder.
Air presser in pneumatic cylinder is controlledby compressor.

Pneumatic cylinders are mechanical devices which uses
the power of compressed gas to produce a force required
for linear motion
Gas forces a piston to move in the desire direction and
piston road transfers the force to the object to be moved
