The palletizer is a machine which is able to automatically sort, transfer, stack and secure packaged goods onto a pallet.
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. It also adds precision that only mechanized and computerized means can provide.
How do they work?
There are three main categories of palletizers, and their operation changes based on their type:
· low level
Robotic or Robot Palletizer
The products arriving on 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. They also occupy less space than conventional palletizers and can service multiple pallets from multiple conveyor belts. However they generally cost more and they also lack their speed.
- Smaller footprint
- Flexibility in handling of different types of products and pallet stacking patterns
- Servicing of multiple production lines
- Lift of up to 1000 kg
- Potential to handle mixed loads on pallets
- They generally cost more than conventional palletizers
- They are slower in servicing a single conveyor than their conventional counterparts. (Speed between 8 to 30 cases/min)
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 on conveyors, where they are continuously transferred to and sorted on the pallets. Both of these conventional palletizing methods are generally faster than robotic methods.
Types of products handled:
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
- Palletizes 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
