Pallets were largely accepted to be one of the two greatest innovations of the Twentieth Century, along with the barcode. And while the use of pallets along with the palletization of materials was once considered to be a powerful component of materials handling strategy, today, industry takes the practice largely for granted. Palletization refers to the process of placing goods or materials, either packaged or bulk, onto pallets.
The pallet provides a base for the goods and materials, thereby promoting the efficient storage, handling and transport for the combination of goods and the pallet base, referred to collectively as the unit load.
In fact, in the effort to continually improve supply chain operations, pallets are sometimes looked at as a technology to be avoided, in an effort to eliminate their cost, their weight, or their cube the space that they require in transport and storage.
And that trend continues to be explored, although it is not new, as is witnessed from the above magazine ad from the s which promoted palletless handling. When the palletization concept was first introduced, however, it had a dramatic impact on the improvement of material handling efficiency.
Rail cars that had taken two days to unload could subsequently be unloaded in just one or two hours. You can read more about the history of pallets. Then as now, the use of pallets as a base for unit loads offers a number of benefits versus unpalletized handling that result from the more efficient handling of goods. These include:. When goods are placed on top of pallets, the containers are typically organized into a Ti Hi, where refers to the Ti the number of boxes per layer and Hi the number of layers.
So a 7 x 5 Ti Hi refers to a palletized load with 7 containers per layer, with a height of 5 layers. Pallet configuration refers to the how containers are placed upon the pallet. Column stacked products are piled directly on top of the product below. Because boxes have the most strength in their corners, this approach provides greater resistance to box deformation than brick or interlocking pallet patterns.
Interlocking pallet patterns, however, are associated with greater unit load stability and bridging strength. The following video explores some of the issues pertaining to pallet patterns. There are four basic approaches to palletization. These are manual palletization, semi-automated palletization, automated palletization and robotic palletization. Manual palletization involves the placement of items on the pallet by the use of manual force.
For example, a worker may lift boxes coming off of an assembly line conveyor and stack them onto a pallet, or if the employee is selecting an order for a customer using a pallet placed on a pallet jack, he or she may remove boxes as required from several pallets to put on the pallet being built for the order. Many companies also offer additional services during the palletization of goods. When performing various warehouse operations, we can close cartons, label them, weigh them, or foil them.
Robotization of loading stations also brings many benefits. First of all, the robots provide repeatability of movements, improve the quality of packaging, and ensure the correct shape of the pallet.
Also, they increase the efficiency of palletizing and packaging of goods. Thanks to robotization, we can reduce storage costs. The use of robots during the palletization of goods also guarantees cleanliness during packaging of food and pharmaceutical goods.
When automating the palletizing process, machines such as palletizers and depalletizers become more and more popular. They are multi-tasking machines that can handle up to several production lines at the same time. A palletizer is an automatically controlled machine used for forming or stacking group packaging or other containers. The depalletizer is used for demolding pallet load units from both group packaging as well as from rigid containers with a defined content.
Finding the right company that deals with the palletization of goods can also greatly facilitate the work of the importer and exporter. There are more and more of them on the market, so the choice is really big. What is the palletization of goods? Using robots to palletize goods is becoming more and more common.
