Robotics stride ahead in food packaging automation

The number one operational improvement in the crosshairs of FMCG companies in the food sector remains automation, particularly robotics, whose implementation and usage that continues to outperform previous forecasts.

According to the Trends and Advances in Food Packaging and Processing report from PMMI, The Association for Packaging and Processing Technologies, in 2014, companies forecasted robotics would be operating in 82% of manufacturing plants in the US.

In 2018, actual usage reached 88%. In 2019, the number of companies using robotics likely ticked up to 90%. In the next five years, nearly all manufacturers will likely be operating robotics somewhere on the plant floor.

Here are four recent improvements that are helping drive this wide-spread adoption:

1. Robotics today are more affordable than they have ever been. 

The initial machine cost of robotics continues to decline, and installation and integration service costs are falling. Reduced programming costs have cut the average time to achieve return on investment (ROI) in the last decade.

In addition, simplified programming and service routines are mitigating the need for retaining costly robotics experts as full-time employees.

2. Robots can be cleaned easily.

As technology has improved, robots can now perform in a range of environments while still conforming with the Food Safety Modernization Act (FSMA).

Sanitation issues were once a deal-breaker for food. But new washdown compatible robots are available and popping up throughout the production line — to the extent that washdown-capable sanitary robots are also finding applications outside of food and beverage in industries that still require hygienic production environments, like pharma and medical device manufacturing.

Washdown-compatible robots provide tangible benefits to food producers by reducing operational costs, improving food safety, and eliminating tasks that pose an injury risk to human operators.

The development of hygienic robotics has also drastically reduced the maintenance costs of robots operating in harsh industrial environments, by up to 60%.

3. Robotics operate at high speed now.

Along with other technologies, such as vision systems, robots can process information at a greater rate and operate at far higher throughput levels than that of a human worker.

Besides improved speed, robots offer a higher level of accuracy and repeatability. This not only improves the rate of production but also reduces downtime and waste caused by human errors, such as incorrect positioning of a product.

4. Robotic grippers can gently handle more products.

With developments in complementary areas, such as gripper technologies, the ability of robots to handle more fragile products and reduce damage has improved significantly.

As this technology continues to grow, this will broaden the potential applications for robot usage. For example, engineers have developed a sensor small enough to be placed on the end of a glove that can accurately measure the direction and intensity of pressure. The sensor is so accurate that a robot equipped with it can safely contact a blueberry or raspberry without crushing it.
