What we have already had before we started to our project..

• The scenario was that the Robot arm which is working relatively with turning table and conveyor

• In the first section, the part is transported by conveyer and sensor detects the part and sends signal to PLC system for stopping conveyor

• Robot arm picks and places that the part on turning table

• After placing, table turns and fix itself for next part• This scenario repeating for every parts

What we have done !

Components that are used ;

• Infrared photoreflect sensors• Relays• LED lights

Components of the System

• Boxes with barcode• 2 Conveyors• Tag reader• Metal sensor• Robot arm• Turning table

TURNING TABLE

Rotation of table is stopped when table appears like it is seen next to this box unlike we started to this project. Each sensor can send a signal to PLC in order to activate reverse motion. For example ;

Imaging that we have turning and milling CNC machines beside of turning table. They are generated a machining cell as FMS. We want to machine the box which is located on number 3 sensor. We can send a command to sensor 3 by using PLC. Table rotates until the box comes the place where robot arm will able to pick the box from the table. Then table stops to rotate and robot can pick the box from table in order to put on CNC milling machine table.

Then we can give same command for sensor number 5 in order to get same action rather than CNC milling machine. This time box will be put on CNC turning machine table.

These actions can be done by this fully smart turning table because it is working with computer and PLC. Also, they are connected with each other.

PLC programing

• Modicon Tsx Micro PLC

Optical Sensor 1.8

PL7 pro= Reverse Motion Program

Same input connection

Normal Motion for Pneumatic Robot

Sensor 8

Conclusion

• System is a simulation of RFID and machining cell• Tracking/monitoring and celling is main purpose of the

system• System can be interfered either on computer that the

system is already connected with the system or from the internet in anytime in anywhere by using host computer

• Scenario of the system can be upgraded by changing PLC programming to be more smart

• Circuit of the turning table can be upgraded to be more efficient
