The palletizer is a machine that is able to automatically sort, transfer, stack, and securely packaged goods onto a pallet, so it’s purpose in manufacturing is to provide a fast and automated means to prepare packaged goods and products for shipping.
Generally it is placed at the end of a production line and it replaces potentially expensive and slow manual labor, therefore it also adds precision that only mechanized and computerized means can provide, but this is the result of the evaluation.
How do they work:
There are three main categories of palletizers, and their operation changes based on their type as follows:
Robotic or Robot Palletizer
The products arriving at a conveyor belt line are picked up by a hydraulic robotic arm and placed onto a pallet in an organized fashion.
Robotic palletizers are very flexible as they can be modified to handle basically any product, Therefore they have lots of naming varieties depending on what they can manipulate:
This is also one of their advantages, and they also occupy less space than conventional palletizers so
can service multiple pallets from multiple conveyor belts, but however they generally cost more, and they also lack their speed.
Advantages are the follow items:
Smaller footprint and
Flexibility in the handling of different types of products and pallet stacking patterns and
Servicing of multiple production lines and
Lift of up to 1000 kg and
Potential to handle mixed loads on pallets.
They generally cost more than conventional palletizers plus
They are slower in servicing a single conveyor than their conventional counterparts. (Speed between 8 and 30 cases/min) so
sometimes are not convenient.
Low and high level palletizers
These conventional palletizers operate with the help of conveyors and an area that receives the goods to be palletized.
Low level palletizers load products from the ground level, while high level ones load from above.
The items to be loaded arrive at conveyors where they are continuously transferred to and sorted on the pallets, so both of these conventional palletizing methods are generally faster than robotic methods.
Types of products handled are the following:
cases, crates, trays, bundles, etc.
Generally costs less than a robotic palletizer because it is less complex, it is easier to maintain and operate.
A maximum of 15 cases/min for low-level palletizers
Up to of 200 cases/min for high-level palletizers
Palletize cases, bags, crates, bundles etc.
The created pallets are very compact
Handles only one type of product at a time
It occupies a considerable amount of space both in height and in area
Maintenance, although easier (requires less specialized knowledge) is more often required
