Centralized method of palletizing articles at the outlets of production lines

A method of palletizing objects, in which use is made of shuttle robots suitable for moving trolleys under the control of a monitoring and control unit in order to handle the objects to a palletizing station where the objects are stowed on a pallet, wherein the palletizing station is shared between a plurality of production lines for producing the objects, which objects are packaged in rectangular box shapes, the method comprising the following steps:

• using the shuttle robots to move the objects for processing on distribution trolleys from the outlets of the production lines so as to place them in a transshipment station where each object is trans-shipped from a distribution trolley to an accumulation trolley on which the object is stacked on other externally identical rectangular box shaped objects that are to be palletized on the same pallet;
• using the shuttle robots under the control of the monitoring and control unit to move the accumulation trolleys full of stacked objects to a buffer storage zone where the identical rectangular box shaped objects on the accumulation trolley are grouped together by batches in shuttle robot travel aisles, the objects of a batch being for stowing on the same pallet;
• and
• preparing a palletizing plan by means of the monitoring and control unit when it is detected that all of the objects making up a batch to be palletized are stacked on one or more accumulation trolleys situated in the buffer storage zone, and once said palletizing plan, has been prepared, moving said accumulation trolleys carrying the objects of the batch for palletizing from the buffer storage zone in order to stow them on a pallet.
