Ladder example of automatic operation (palletizing operation)
A palletizing operation is automatically performed.
The machine moves to a target coordinate, then returns to the start position. Next,
the machine moves to a position further away than the target coordinate, then again
returns to the start position. Such an operation is realized using repetitious and
return movements. This type of operation is suitable for, for example, a job where
workpieces to be supplied are located in one position and a moving body picks up
the workpieces and positions them little by little at a certain interval.
When start signal 0000 is set to ON, a moving body moves to point 1, returns to the
start position, moves to point 2, and then returns to the start position again. After-
wards, the moving body moves to point 3, then returns to the start position, output
05000 remains ON for 3 seconds, and then the operation is finished.
