Palletising is a type of handling application but owing to the huge number of installations that directly involve the use of pallets this has become a subset of its own. KUKA and other manufacturers have even designed specialist palletising software packages and even palletising robot arms although in practise these are not often needed.
The principle is simple, the robot picks part or parts from one or more positions and the places them in sequence. This is usually on a pallet, stacking for example bags of cement, in such a way that will stop the stack from easily falling over. This could also mean placing parts into a stillage or other rack but the most important part is that the robot keeps count of the position to which it has gone and must go to next. Count functions were one of the first logic functions included in robot controllers and are probably one of the most used.
In a palletising job the robot will often pick the part, box or bag from a conveyor either using conveyor tracking or more simply at a fixed point and then put the parts in order until the pallet is full. The pallet can either be changed by hand (with the robot stopped or working in another area) or the full pallet can be carried away on a second conveyor for wrapping etc. If needed the robot itself can pick an empty pallet from a stack and start palletising again saving operator time and effort.
