Number of IRB 360 -3/1130 for 200 PP operations per minute

Hello to all, what would you recommend for operation of packing 200 pieces per minute, from two side conveyors robots are picking and placing in middle conveyor trays. Bags weight is max. 80 grams, we are thinking about double or triple pick with one robot. Distances from conveyor to conveyor are around 400 mm. Should we go with 2 or 3 robots? Thanks.
