When the robot is actively palletizing the output of one line, it records the pallet loading status and shifts to another line upon receiving a signal from one of the other lines. Or, if sensors indicate that product is no longer available on the line being palletized, the control system checks to see which line has the most product queued up and transfers production to that line.
The newest model in the PR-Series of palletizing robots from Pacific Robotics (San Diego, CA) palletizes four different products from four infeed lines at the same time.
