An automatic robot and stacker is today the most efficient way of palletizing piece goods onto pallets of any size and removing them from pallets. There are several explanations for this. Firstly, the palletizing operation can be easily robotized, as it is a series of sequentially repeated operations of the same type that can be easily written in a palletizing robot program. Secondly, the stacker robot can be easily reprogrammed and reconfigured not only from one stacking scheme to another, but also from one type of product to another, of course, if the grip and lifting capacity allows. Palletizing robots are absolutely universal in this respect.
The work of the stacking robot in general looks as follows. The goods to be palletized enter the feeding conveyor, the other conveyor receives the pallets from the pallet dispenser, the stacker robot picks up the goods and places them according to the palletizing scheme. After stacking a predetermined number of objects, the pallets are moved further along the conveyor to an automated pallet wrapper. Laying by robots is used today for a wide variety of products. This can be robotic stacking of bricks, bags of finished products, boxes, etc.
The reverse operation of palletizing is depalletizing. In this operation, the robot removes objects from the pallet and transfers them to a conveyor or machine for further processing. Today, robotization of CNC machines is becoming more widespread, in which a robot takes blanks from a pallet, places them into a machine, after processing, grabs finished products, takes them out of the machine and places them on another pallet.
In summary, there are three main areas of use for stacking robots:
stowage of products in primary packaging;
packaging of products in corrugated boxes and other containers;
stacking of products on pallets and removal from pallets.
