Palletizing 101

End of line automation solutions

End of line automation solutions

A flexible palletizing system can increase your throughput and reduce your costs. Motion Controls Robotics develops robotic palletizing systems that are highly reliable, flexible enough to handle various configurations and allow for process adjustments on the fly. Each application is custom designed to take into account the customer’s process considering options such as pallet size, tier sheets, inserts, top frames, and product order. While Palletizing 101 will focus on palletizing, many times palletizing systems are conveniently combined with pick and place applications to automate an entire end of line process.

Palletizing Robots

FANUC America offers a variety of robots for palletizing applications. These robots all have software and vision options available to increase the flexibility and fine tune the process. Designing the cell by looking at future needs, helps to make your robots reusable and re-deployable if there are product changes.
Palletizing robots generally offer a 4 or 5 axis design.

  • M410 series– With payload options up to 700 kg or 1500 lbs including end of arm tooling, the M410 series offers the best selections for payload and reach, with the ability to palletize full truckload height pallet loads up to 108” tall. The M-410 is the most popular palletizing robot.
  • R2000 series – Mounting options are highly flexible with the R2000 series – making this the perfect robot to use for distribution centers or loading freezers.
  • R1000 series – This series is very compact and high speed, with lower capacity and shorter reach than the R2000 or M410 series.
  • M710 series – The M710 has a variety of models available for payload and mounting options. The M710 is perfect for lower throughput jobs that might change daily. MCRI uses this model in their ErgoPakPal to both pack and palletize product using one small footprint cell that can be easily moved to new locations in the facility.

Palletizing Applications

Some palletizing applications think outside the box or case, because there are a variety of product types that need palletizing. This is where the robot integrator uses experience in the industry to best design a multi-gripper end of arm tool that will match the application requirements and the robot selected.

Types of palletizing applications include:

  • Case Palletizing/Depalletizing – Needs for case palletizing vary, but in most cases the customer wants to find the most efficient way to palletize and follow guidelines for labeling. This can be done by single case palletizing or mixed case palletizing. It is also becoming popular to automatically palletize shelf-ready display packaging and floor display pallets for distribution centers and retails stores.
  • Bag Palletizing/Depalletizing – Many products such as pet food, food ingredients, building supplies, lawn and garden products and other bulk products require a bag palletizing or depalletizing solution. Bags can be very heavy and awkward so automating the process is the best choice for employee safety.
  • Random Order Palletizing/Depalletizing – This application is common for distribution and warehousing where products need to be individually picked and palletized. FANUC’s Random Order PalletTool software provides efficient methods for setting up, controlling and monitoring mixed load palletizing applications.
  • Freezer Palletizing/Depalletizing – Frozen material handling commonly uses a ceiling or floor mounted robot on a rail for flexibility in removing or adding items to a freezer area.
  • Heavy/Bulky Material Palletizing/Depalletizing – Similar to bag palletizing, some loads are too heavy for employees to lift all day long. The best option is to automate the process. This applies to items such as bricks, cement blocks, and panel stacking of boards, insulation or cement.
  • Roll Palletizing– Robotic palletizers handle product gently. Robotic palletizers can improve quality control of rolled product and other easily damaged loads, versus manual palletizing or hard automation. To secure tall, vertically palletized rolls such as roofing materials, an inline stretch wrapper can be supplied with the robotic palletizer.

Technology

FANUC’s PalletPro software allows the robot programmer to input product and pallet dimensional data into a user friendly interface, and to find the best pallet configuration for the application. Steps of the palletizing operation are defined for items like:
• Gripper type
• Orientation requirements for infeed boxes
• Custom Pallet Patterns


Once production data is entered, FANUC simulation software can be used by the robot programmer to check for proper system behavior. The PalletPro software reports efficiency calculations so the programmer can decide which process works best. Read more about PalletPro>>

Advanced Technologies

FANUC offers a range of advanced technologies to improve and fine tune robotic applications.

  • iRVision/Machine Vision – Vision systems are used in almost every automation process for managing part location, inspection and tracking/bar-coding purposes.
  • 3D Area Scanner (3DAS) – A 3D vision map is developed to scan for products to pick. This can be used to keep pallets straight and to depalletize pallets that have shifted.
  • Dual Check Safety (DCS) – Safely gives the ability to design safe zones for working with robots. This technology helps decrease floor space needed in the manufacturing environment.
  • Force Sensing – Force sensing can be used in many ways to dynamically cause a robot to change or maintain forces applied at the end of arm tool. It can be used in a depalletizing operation to check for interference between end of arm tool and the load, for example, or prevent damage to an expensive end of arm tool.

These sensing and safety technologies allow for more efficient, higher quality and more flexible automated palletizing solutions.
