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.

HANDLING DEVICE


11/1611

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
