System of Sorting and of Distributing consist of two jobstation, station of distributing, and station of
sorting. the Robot system can form one integrated sequence system or form independent job
Station of Distributing undertake to take workpiece from magazine and channelling it to next
process station. Of station of distributing this [is] we earn to study application and pemograman of
PLC by using switch limit.
Station of Sorting undertake to chosen material type to be processed, for example only
workpice with material of metal type / metal or other type. Of station of sorting this is we earn to
study application and pemograman of PLC by using some sensor.
As for Station components of Distributing PLC Board, Valve Terminal, Input of Output ( I / O),
Transfer Of Module, Feed Magazine and Work piece.
This final duty, position control analysed by writer use two PLC Type of Siemen S-700 as
processor. For the operation of its position happened communications between PLC using data
communications serially have the character of duplek half use protocol of modbus its
communications media use cable of RS-232. Such position control can be depicted with transfer of
workpiece position of station of distributing to station of sorting. Besides appliances above there
[is] component which cannot be eliminated by its role that is component of pneumatik. With
Component of pneumatik can do some movement type. While elektropneumatik represent
combination of energi between pneumatik and is electrical. Pneumatik Power come from
compressed air while electrical come from electrics.
Role of PLC in this case is to arrange supply power to component to be moved ( actuator). [At]
elektropneumatik, PLC arrange on-off of electrics resulting to emit a stream of / do not it
compressed air to actuator ( for example cylinder) so electrics resulting to emit a stream of / do not
it compressed air to aktuator ( for example cylinder) so that yield a[n certain movement.
Component using elektropenumatik [is] solenoid of valve. solenoid of Valve move spillway (
position open / cover) because of electrical suppy [at] Ianguage solenoid of software used [at] final
duty use Ladder Diagram. Its Software have been made by factory in this case by side of festo.
Result of study indicate that Station of distributing station and of sorting walk better but its
operation have to be paid attention carefully especially by operator because workpiece sometime
cannot walk so that the machine stuck so that the workpiece have to be assisted by hand. Or
overdue workpiece entered to this feed magazine also will arise the problem of because the
machine happened jam so that operator have to repeat step from early again by button reset.
