The Revolutionary Impact of Robots on the Packaging Industry

The packaging industry is undergoing a significant transformation, largely driven by the integration of robotic technology. From palletising to inspection, robots are revolutionising how packaging tasks are performed, saving companies time and money while reducing physical strain on human workers. Here, we explore the key ways autonomous robots are changing the game in the packaging industry and delve into additional relevant insights, including the type of industrial computing and technology involved.

Packing robots are automated machines designed to handle various packaging tasks in factories and warehouses. These robots can pick up products, place them into packages, seal, label, and palletize them for shipping. By automating these repetitive and often strenuous tasks, packing robots enhance efficiency and ease the workload of human employees. While there are concerns about robots replacing jobs, they primarily take over the monotonous tasks, allowing human workers to focus on more complex and fulfilling activities.

The cost of packaging robots varies based on their complexity and capabilities. Basic robots start at around $50,000, while more advanced systems with vision and intelligent palletizing features can range from $75,000 to $250,000 or more.  Large industrial systems can cost between $200,000 and $500,000. Despite the high initial investment, companies often see a return on investment within 2-3 years through increased productivity and reduced labour costs.

Packing robots operate using sophisticated systems that include robotic arms, grippers, sensors, cameras, and advanced software. Here’s a closer look at how they function:

• Robotic Arms and Grippers: The core components, robotic arms and grippers, are designed to move smoothly and handle products with precision. They are assisted by sensors and cameras that provide the necessary data for accurate operation. These arms are capable of reaching wide and far, ensuring that every product is picked and placed correctly.
• Precision Handling: High-quality sensors and cameras enable the robots to handle products gently and accurately, adapting to various package sizes and patterns. The technology ensures that each product is picked and placed just right, avoiding damage and maintaining quality.
• Pathfinding: Robots use vision systems to identify products and determine the best routes for movement, making them increasingly adept at complex tasks. This adaptability allows robots to handle various packaging scenarios, from straightforward tasks to more intricate manoeuvres.

Routine Tasks: Robots excel at performing repetitive tasks reliably and quickly, freeing up human workers to concentrate on higher-value tasks. By taking over the monotonous aspects of packaging, robots contribute to a more efficient and productive workflow.

Robotic palletizing involves stacking small boxes or packages onto larger pallets for transport and storage. Robots equipped with vacuum or mechanical grippers can palletize boxes at high speeds, significantly outpacing human workers. This not only boosts efficiency but also reduces the risk of workplace injuries from repetitive manual palletizing tasks. Industries such as food and beverage, cosmetics, and pharmaceuticals widely use robotic palletizers to streamline their operations.

Robotic palletizing systems use advanced algorithms to determine the optimal stacking pattern, ensuring stability and maximising space utilisation on pallets. These systems can handle various package shapes and sizes, making them versatile and adaptable to different industries. Additionally, the robots’ ability to work continuously without fatigue makes them ideal for high-volume operations, where consistent output and reliability are crucial.

Many types of companies in the packaging industry employ robotic palletizers, from food and drink producers to cosmetics and pharmaceutical companies. These robots not only enhance operational efficiency but also contribute to a safer working environment by eliminating the risk of injuries associated with manual palletizing.

Case packing, a labour-intensive part of product packaging, is being transformed by robotic technology. Robots can group items into cases, seal them, and move them onto pallets with high speed and accuracy. This automation reduces the physical strain on workers and increases job satisfaction. In high-volume operations, robotic case packers are essential for maintaining efficiency and throughput, packing up to six cases per minute, a rate unattainable by human workers.

Robotic case packing systems utilise advanced vision systems to identify and group products accurately. These systems ensure that each item is correctly positioned within the case, reducing the risk of damage during transit. Furthermore, the robots’ ability to handle various product types and packaging configurations makes them highly flexible and adaptable to different production needs.

In addition to improving efficiency, robotic case packing systems also contribute to better quality control. By automating the case packing process, companies can ensure that each case is packed consistently and correctly, reducing the likelihood of errors and improving overall product quality.

Robotic arms equipped with vision systems and heat sealers can inspect and seal product boxes with remarkable speed and accuracy. They can inspect multiple sides of a box in a single cycle, ensuring consistent quality and reducing product damage and spoilage. Automated inspection systems further enhance quality control by identifying any sealing flaws or packaging errors before shipment.

Robotic heat sealers or box tapers precisely apply tape, glue, or heat to securely seal cartons. They ensure each box is properly sealed to protect the contents inside, while advanced vision guidance systems enable the robots to locate the box edges and seams with high accuracy for an optimised seal. Compared to manual box sealing, robots are faster, more consistent, and help reduce product damage and spoilage.

After sealing, the boxes undergo automated inspection. Vision systems scan each sealed box to check for any flaws or imperfections in the sealing, as well as verify the contents and placement inside the box. This helps identify any boxes that may need resealing or repacking before shipment. Automated inspection massively improves quality control and ensures only properly sealed and filled boxes continue down the line.

Depanning involves removing individual products from pans or trays and repacking or palletizing them for shipping. Robotic depanning systems use arms with grippers or vacuum tools to handle products efficiently and accurately. These robots can depan up to 120 cartons per minute, significantly easing the physical burden on human workers and preventing repetitive strain injuries. Depending on the product, robots may be stationary or mobile, adapting to different production environments.

Robotic depanning systems can be customised to handle a wide range of products, from baked goods to electronics. The choice of gripper or vacuum tool depends on the product’s characteristics, ensuring gentle handling and maintaining product integrity. Stationary depanning robots typically remove items from pans as they pass by on a conveyor, while mobile robots move down aisles of stacked pans, depanning each one.

The use of robotic depanning systems not only increases efficiency but also improves the overall quality of the packaging process. By automating this repetitive task, companies can ensure consistent and precise handling of products, reducing the risk of damage and improving overall product quality.
