Some of the production lines are fed and discharged by robots and when depalletizing, the robots tool, single or double head, uses a vision system to detect the position of the keg on the pallet. Any foreign, damaged or overweighed keg will be placed on a reject conveyor.
The acceptable kegs are turned, de-capped and placed onto a conveyor or directly onto a racking machine. Full kegs are picked up from the racking line, turned, weighed, capped, labelled and code read before they are placed on the pallet. Depending on size, speed and weight the robot can also stack kegs on pallets up to 2 or 3 high.
