A device is described for changing pallets in an automatic palletizer that arranges objects on the pallets. The object was to refine such a device in such a way that it not only minimizes the space occupied by the automatic palletizer, but also enables the length of interruptions in the palletizing process to be reduced. To solve this object, it is suggested to provide a transfer vehicle having a first pallet area for receiving a first pallet, and a second pallet area for receiving a second pallet, and a driving arrangement for moving the transfer vehicle between at least a first position and a second position, wherein when the transfer vehicle is in its first position the first pallet region of the transfer vehicle can be loaded with an empty pallet while the objects can be arranged on a pallet in the second pallet area.
