Palletizing is an essential process in the packaging and logistics industry. It involves stacking products or goods onto a pallet, securing them in place, and preparing them for storage or transportation. This method of handling and storing goods has been around for decades, but with advancing technology and ever-evolving industrial demands, the process has undergone significant developments. In this comprehensive guide, we will discuss everything you should know about the palletizing process, including its history, the different types of palletizers, and current industry innovations.
The History of Palletizing
The concept of palletizing dates back to ancient times when merchants transported goods on wooden skids. However, it wasn’t until the 20th century that the modern form of palletizing entered the industrial scene.
Manufacturers realized the efficiency and cost-saving benefits of stacking goods on a standardized platform for storage and transportation. This concept led to the development of manual and semi-automatic palletizers in the early 1950s. With the introduction of computers in the 1980s, fully automated palletizers hit the market, further revolutionizing the packaging industry for many goods requiring bulk transportation.
Types of Palletizers
Palletizers are broadly classified into three primary categories: manual, semi-automatic, and automatic. Each type has its own unique characteristics and applications. We explore these three primary categories in more detail below.
Manual Palletizers
Manual palletizing is the most basic form of palletizing, where workers manually stack goods onto a pallet using their hands or simple tools such as forklifts. This method is ideal for small-scale operations or when handling irregularly shaped products that automated systems cannot handle.
However, manual palletizing is labor-intensive and time-consuming, making it less efficient compared to other types. It’s essential to note that manual palletizing is still a viable production solution where it fits. It’s always best to partner with a palletizing company to ensure that your existing process is the right fit for production.
Semi-Automatic Palletizers
Semi-automatic palletizing involves a combination of manual and automated processes. Workers manually load products onto the pallet while the machine takes care of stacking and securing them in place.
This type of palletizer is ideal for medium-scale operations that require a higher level of precision than manual palletizing but do not have the volume to justify fully automated systems. A semi-automatic palletizer is rarely a bad choice, but it’s always advantageous to have a palletizing company work with you to streamline manual processes.
Automatic Palletizers
Fully automatic palletizers are the most advanced and efficient type of palletizing systems. They use robotic arms and other traditional automated processes to handle large volumes of products with precision and speed.
Businesses can customize these machines to handle various types of products, making them suitable for a wide range of industries. However, they also come at a higher cost compared to manual or semi-automatic palletizing.
It’s worth noting that the initial cost of an automatic palletizer helps eliminate the costs of ongoing manual labor or mechanical breakdowns on semi-automatic systems, which pays for the machine over time (ROI). Some warehouses benefit more from fully automatic processes that reduce the cost of manual labor. Once again, it’s worth partnering with a palletizing company to weigh all options and determine what fits your company’s needs.
The Palletizing Process
Now that we explored the three main palletizing systems, let’s discuss the process in more detail. The palletizing process involves several steps and components working together to ensure efficient and safe handling of goods. From infeed and stacking to physical palletizing, let’s explore this beneficial process.
Infeed Section
The first step in the palletizing process is feeding products into the machine. Workers can do this step manually or with the help of a conveyor system that moves products from one end to the other. Some advanced palletizers also have an automatic loading feature that uses robotic arms to pick up products from a designated area.
Stacking Section
Once the products enter the machine, they pass through the stacking section, where the machine can arrange and stack them onto a pallet according to a predetermined pattern. This step is where different types of palletizers differ in their capabilities. Manual and semi-automatic systems may require workers to manually place products onto the pallet, while automatic systems use robotic arms for precise placement.
Palletizing Section
After the products are on the pallet, they move to the palletizing section, where a machine can secure them using stretch wrap or other securing methods. This step ensures that the products remain stable and intact during storage and transportation.
Outfeed Section
The final step in the palletizing process is moving the finished pallets out of the machine via conveyor automatically. Some advanced systems also have automatic pallet dispensers that stack empty pallets for future use.
Advancements in Palletizing
With the increasing demand for faster and more efficient palletizing, manufacturers constantly work to develop new technologies that improve the process. One of the latest advancements is concurrent stretch wrapping. This feature is a “built-in” stretch wrapper that wraps each layer as it is being built by the palletizer. This all-in-one system saves valuable floor space and is an overall less expensive option than purchasing an automatic palletizer and separate stretch wrapper.
Meanwhile, a low-infeed palletizer offers a shorter height between the conveyor and stacking sections, allowing products to enter the machine from a lower level. This lower height reduces manual labor challenges and minimizes product damage by eliminating height drops.
