Palletizing works better with dimensionally stable product. For bags, which can have an unpredictable flow behavior, this can be a challenge. This twin-belt turning device, though, helps palletize bags filled with bulk material in an even, gentle way. The twin-belt turning device works with two separately driven belt conveyors, which, by applying a differential speed between both belts, enables turning the bag to be palletized by 900, and, in particular cases also by 1800. This procedure ensures a dimensionally stable bag.
The twin-belt turning device is used with the BEUMER paletpac high-capacity palletizer. With a stack height of up to 2,400 mm, the unit palletizes bags on any commonly used pallet size and in all technically feasible packing patterns. The variable bag and pallet sizes are adapted by rapid parametric setting with multi-programming. This system puts the bags into the desired packing pattern in a quick and gentle way.
Once the user has set the desired packing pattern, the device turns the bags with the help of two separately driven belts arranged parallel to one another. The rotation of the bag is initiated by the net weight of the bag and by the different speeds of the belts. The speeds and also the rotation of the bag are adapted to the different bag sizes by a self-optimizing highly dynamic active control loop. Each belt conveyor is provided with a synchronous servo drive, which accelerates and decelerates during the turning process. The device has fewer parts subject to wear and tear. The new module operates at extremely low noise and existing palletizers can be easily retrofitted.
