Paint boat manipulator

Vacuum manipulator whose function is to place the cans on pallet, forming a quincunx mosaic. On the pallet there are alternating rows of three and four boats. For this purpose there are four suction cups, and a manual valve to cancel one of them when it is necessary to take only three cans. In this case you also have to release a latch and slide the guide so that the center of gravity is the same when handling three or four boats.
