Conveyor Synchronized Function with Shift Functions
In the conveyor synchronized function of the position tracking type, the
taught motion path of the manipulator is corrected according to the
conveyor travel amount so that the manipulator performs follow-up motion
in the conveyor moving direction at a constant relative speed to the
workpiece.
There are two conveyor synchronized function types:
Manipulator follow-up control: The manipulator’s basic axis moves in
synchronization with the conveyor movement.
Travel-axis follow-up control: A travel axis (external axis) moves in
synchronization with the conveyor movement.
When the conveyor synchronized function is used with “shift functions,” it
is useful for a situation where the conveyor home-position limit switch, the
workpiece identification detecting limit switch (WORK ID detecting limit
switch), and the workpiece detecting limit switch (WORK IN/ NOT
detecting limit switch) cannot be installed near the manipulator. Using the
conveyor synchronized function with shift functions, the information of all
the workpieces that pass all the limit switches to reach the synchronization
start position of the manipulator can be managed.
And then, when a workpiece reaches the manipulator start position, the
corresponding job is started so that the manipulator can start the job in
synchronization with the conveyor.
In such operation flow, the section from each limit switch to the
manipulator start position is defined as “shift section,” and the section from
the manipulator start position to the synchronization start position of the
manipulator is defined as “synchronized section.”
