Conventional Palletizer History

Historically speaking, you had to choose between conventional palletizers for their speed or robotic palletizers for their flexibility, but you could not have both. Conventional palletizers see it can often handle more complex stacking patterns than other palletizing technologies. One of the major problems with layer palletizers is that they don’t accommodate mixed pallets or changeable product sizes and shapes. They also have strict restrictions as to the type of packaging material that can be handled in the machine, with light, delicate, and fragile objects being difficult or impossible to accommodate. The benefits of automated robotic palletizing can be considerable, if implemented well.

Initial costs of the conventional style palletizer vs. the robotic style palletizer are similar. The robotic palletizers typically require less upstream conveyor and have a smaller footprint, but the conventional palletizers can reach those high speeds. Your choice ultimately comes down to your product and the operation you wish to run. Conventional Palletizers are best for building single SKU pallets quickly.If you have long production runs with the same SKUs and the same sized cases, a conventional palletizer will likely meet your needs. However, robotic palletizers are more flexible and reliable for palletizing multiple SKU pallets. The ARBOT is a pre-engineered robotic palletizing cell that automatically stacks and wraps pallets to your exact specifications.

Another group of palletizing systems are in-line palletizer systems, which are systems designed to stack complete layers of bags or cartons at one time. Palletizers are used to repeatedly lift, rotate and wrench wood pallets and plastic pallets on their own. | At JR Automation, our palletizing solutions will increase efficiency and reliability throughout your e-commerce and manufacturing processes.

These reliable pallets can be easily identified by the blue paint on the pallet’s sides. There are three main types of wood or plastic pallets and one for cardboard. Linear actuators offer horizontal and vertical motion with travel up to 500 feet, speeds up to 600 in/sec., and can accurately handle loads up to 10,000 lbs. Get a firm guarantee on robotic rates, including consequences if those rates are not met. We send e-newsletters about packaging machinery, partner news, company news, updates and related communication. Occasionally, we will notify you when factory representatives are visiting in the area. Other important considerations include the different sizes, weights, and shapes that the system needs to handle, as well the packaging material.

To make the pallet more enticing to customers, warehouse retailers require a pallet pattern that has labels facing outward. A robotic palletizer can be programmed to stack the cases into that pattern, ensuring the labels in the stack are visible from all directions.

Robotic palletizers generally take up less space compared to conventional palletizers, and they can sometimes be less expensive depending on your application. A robotic palletizer has the ability to work on multiple types of Skus and pallet designs, whereas a conventional palletizer is often limited to a specific type of pallet design.

Once a layer has formed, the end stop is removed and the layer is conveyed to a layer-handling robot. Pallets are placed in the designated area either manually or by an automated pallet dispenser. The palletizing system may or may not be programmed to place a slip sheet on the pallet. Sprains, strains, tears, and overexertion are the most common workplace injuries in the US. Generally, these are caused by repetitive motion, lifting large or heavy items, or both. Manually stacking and unstacking product onto and off of pallets is exactly the kind of work that can lead to injuries.

• Thus, robotic arms are a cheaper option provided that it can cope with the required throughput.
• Typically there are two styles of robotics used; an articulated arm robot or a Cartesian gantry style Linear robot.
• Because they never have to pick up the product, conventional palletizers are more tolerant of packaging changes.
• Both arguments have their merit and the concrete advantages of robotic palletizing over conventional are somewhat marginal.
• Different speeds of the rollers allow the product to rotate +90°, -90°, or 180°.

This is especially true with lightweight packaging that has become a sustainability trend. Downstream stretchwrappers can be easily integrated with a single or multiple cell palletizing system so that pallets leaving the palletizing conveyor will stay straight and tight. Wohlrab says more environmentally friendly packaging with more desirable graphics for consumers continues to impact the palletizing and de-palletizing market. "Those changes lead people towards robotics." The speed of robotics is always increasing and will soon rival conventional case palletizers when manipulating less rigid packaging, Wohlrab concludes. Kelley Supply's staff members began working in palletizing in the early 1980's. Our experienced staff members have designed and built all types of palletizers for almost all types of systems for most types of packages. We have built and installed packaging and palletizing-related systems in over 40 states and 5 countries.

Chapter 3: Types Of Palletizers: Conventional

Before automatic palletizing, manual hand stacking is employed to organize products into pallet loads for storage and distribution. This method tends to be slow where a lot of work is needed relative to the output. Pallets and pallet handling became one of the most important logistics tools in the early 20th century, particularly during World War 2. As the transport of heavier loads at a faster pace became progressive, a need for new material handling and storage capabilities followed. Unit load refers to the assembly of materials combined for efficient handling. It is faster and more economical to move a large, single unit instead of several small individual items.

“Vision plays a big role in guiding the robot in de-palletizing applications. Improvements to end-of-arm tooling, software, and vision systems have pushed flexible robotics downstream of manufacturing to perform palletizing and de-palletizing tasks. Subsequent to manufacturing, robots also apply packaging and ready these packaged goods for transport by stacking assemblies onto pallets for distribution. Range of conventional and robotic palletizers based on speed requirement & formats that needs to be handled. End-of-line palletizing solutions are designed for environments with very high production volumes, from 20 to 150 packs/minute, or where the customer prefers to connect the production machines directly to the palletizer. However, with the recent innovation of the PLC-controlled robotic arm, this automaton becomes less of a "black box" or foreign concept and is suddenly a more familiar piece of machinery.

Palletizing products requires repetitive bending over and lifting of items, which puts strain on a worker’s body. This can lead to work-related injuries which are expensive, time-consuming, and cause production delays.

Automated palletizing has seen tremendous advancements over the last several decades. Brenton offers robotic palletizing solutions for bulk cases and containers as well as standard depalletizing applications. Each solution is customized to the application to increase throughput and efficiencies through the robotic automation.

In most installations, an elevated operators’ platform is constructed together with the machine. These palletizers use a robotic arm with an end effector or product gripper which picks up the product from the conveyor or layer table and then positions it onto the pallet. Palletizer manufacturers understand these challenges and have designed equipment that is capable of palletizing most any type of product and work with various pallets, slip sheets, unitized loads and AS/RS systems. Palletizing can be solved with one of two technologies, conventional or robotic.

Probably the best option for most palletizing tasks is to go for a dedicated palletizing robot. Unlike 6-axis industrial robots, these usually only have 5 axes as the end effector only ever needs to be pointing downwards. They also tend to use axis coupling, a feature that allows them to handle heavier payloads without reducing the speed.

The different models handle a diverse range of bags, working with paper, plastic, or poly woven bags. Additionally, the Series 2000 palletizers easily work with multiple bag sizes and layer pattern flexibility with rates up to 40 bags per minute. All of our systems from the automatic to the conventional palletizer work with all pallet types and with “slip-sheet-only” stacking. Dematic’s automated palletizing systems provide reliable performance and may be designed to handle individual cartons or full pallet layers of goods in higher throughput applications. So, robots can handle difficult-to-handle loads, but conventional palletizer can handle higher speeds. Conventional machines can make pattern forming a breeze, but robots can create more retail-friendly loads.

Both arguments have their merit and the concrete advantages of robotic palletizing over conventional are somewhat marginal. The reason robotic palletizers have found such success in North America comes down largely to the nature of the region’s machinery sector. Hybrid applications, which use robots as components of a machine, are experiencing a growth in adoption as advanced processes like mixed-load palletizing become automated. As mass production lowers robot costs and breakthroughs in technology enhance the speed and quality of packaging lines, more applications, such as stabilizing tier sheets insertion, will be performed robotically. The dual system OEM will be neutral in finding the best solution, while the single system OEM can only respond with its solution, not necessarily the best solution.

The rows move onto a layering table, which then drops them carefully onto a pallet for the load arrangement. There’s also a high-level palletizer that works similarity, but instead of raising and lowering the different layers to build a pallet, the pallet itself is moved to help build the layers.

From the name itself, this part dispenses and conveys pallets for continuous operation of the palletizer. When one unit load is completed, a new pallet is fed by the pallet dispenser. A pallet dispenser usually has 10 – 20 pallets stored in a pallet magazine. Detected products that are either off-weight or contain metal contaminants are then moved by the reject conveyor onto a staging area or platform. Other palletizers can also stack items on a slip sheet or conveying surface. In other references, palletizers and unitizers are used interchangeably. No robotics system is as easy to operate and troubleshoot as the salesperson will report.

Whether you’re moving from hand palletizing or looking to upgrade your automatic operation, we're here to help you get more from your line. range of food, chemical, pharmaceutical, nutraceutical, mineral and agricultural products. PMR Packaging Inc., established in 1991 and located in Whitby, Ontario, is a leading agent and distributor of packaging machinery and equipment. We represent packaging machinery manufacturers located throughout the world whose focus is on engineering technology and innovation for the future. Manually placing boxes on pallets can be time consuming and expensive; it can also put unusual stress on workers. The first mechanized palletizer was designed, built, and installed in 1948 by a company formerly known as Lamson Corp. Adding SKUs or changing packaging can change the end of arm tooling, or even the style of robot.

The trick is determining which solution is the best fit to meet the other parameters in an application. Downtime for robotic automatic palletizers is considerably less frequent than traditional. ABB robots are able to execute up to 400,000 hours which is equivalent to more than 45 years of labour! An automatic palletizer can provide up to 60 bags per minute, however, it is still possible to increase this rate by integrating a second robot to the cell which optimizes speed. These environments also utilize advanced robotic tooling to enable the flexibility needed to handle a variety of separator sheets and boards, per each manufacturer’s unique requirements.

Applications

Since the 1950s, conventional automatic palletizer has brought speed and reliability to manual warehouse processes. In the 1990s, gantry and jointed-arm robots made significant inroads into palletizing, giving operations more automation choices than ever before. Certain applications are better suited for robotics, while others favor conventional automation. It’s important for operations to choose a palletizing technology that best fits their current and future material handling needs, and offers a sound business case for automation. Conventional palletizers can handle much higher speeds than robotic arm options. They tend to be found in food, beverage, and consumer goods industries and can be more flexible than robots for product packaging and stacking patterns.

Rather, one arm is mounted into a swivel joint with a fixed base which allows more flexible movement. This type is faster than the SCARA that can handle multiple production lines at about 25 items per minute.

There are specific packaging machinery needs related to predictive maintenance, and a new PMMI Business Intelligence report researched what is most prominent. Among all the regions, North America accounts for the largest market share due to the high penetration of packaging machinery in the region. According to Packaging Machinery Manufacturers Institute , the North American US domestic market for packaging machinery is estimated to be worth USD 9 billion in 2022. Integrated multi palletizer and stretch wrapper combo system.When discussing the project with the OEM determine whether the technical and project management teams have a track record of success. Is it off in an unused corner of the building or does the OEM have a properly outfitted and spacious staging area for the factory acceptance test? It will become apparent quickly whether the OEM is right for the job of supplier and integrator. Clamps can collect and place multiple products with the same orientation at the same time, allowing for faster throughput.
