Robotic systems set to aid food manufacture growth in the wake of Covid-19

Robotics and automation is set to play an increasingly larger role in safeguarding the future of the UK’s food manufacturing industry, according to Endoline Robotics, the strategic partner of FANUC UK.

While most UK food manufacturers understood the efficiencies gained from automation, adoption was at a far slower pace than other countries. However, Covid-19 has emphasised the need to update manual manufacturing practices that will prevent many from recovering quickly once social distancing measures are lifted.

According to a recent post by the International Federation of Robots (IFR) in comparison to several countries across the world, the UK was the only country, over a 10-year period, to report a 9% decrease in productivity per person.

While coronavirus undoubtedly put a strain on global productivity, UK manufacturers faced significant issues because of workers being unable to work in production lines where they normally stand less than 50 cm apart on 12-hour shifts.

There is an established link between automation and increased productivity, so now is the time for UK manufacturers to look at long term growth and invest in robotics and automation to support labour intensive activities.

So, why have UK food manufacturers always been so reluctant to take the automation plunge?

Here, Grigory Belosky, Sales Director for Endoline Robotics, discusses the reasons why the UK lagged behind its global counterparts, how automated end-of-line packaging systems today meets manufacturer demands, and how machinery can be integrated into processing and packing lines quickly to ramp up output.

Demonstrating flexibility

For some food manufacturers, a wariness to change well established manual processes, and an aversion to the risks that new technologies can bring, have created major roadblocks, preventing them from reaping the many benefits robotic systems can yield.

Within food manufacturing, the variability of materials has played a major factor, particularly as many believe that uniformity plays a vital role in ensuring automation runs efficiently. To meet retail demand, manufacturers are producing an abundance of brand varieties in all shapes and sizes which can cause greater complexities, due to the variation in size, shape, quality, and weight of the product.

“Retailers are constantly vying for consumer attention, creating greater choices which are continually changing. Historically, this hasn’t always lent itself well to automation and manufacturers need assurances that the investment they make in robotic equipment is future-proof.”

Today, robotic systems can not only boost productivity and efficiency, they are tangible assets which can be moved or easily re-programmed to meet changing demands. Robotic palletising systems in particular, as they are outside high-care areas, are extremely flexible and can take the strain of monotonous and repetitive tasks off human workers, freeing up their time to complete more value-added tasks.

Health & Safety

Getting health and safety right has never been more paramount. Food manufactures need to adhere to stringent measures and are being set greater guidance on the use of machinery through the Food Standard Agency’s regulatory model, facing stiffer sentences if they are non-compliant.

Tougher governance around health and safety shouldn’t be a deterrent to automation, however it is vital that manufacturers do not take a CE certified machine at face value.

 “There are a number of other factors which need to be considered. Manufacturers need to understand the area the machine will be located in and assess the environment for any safety concerns such as access.”

Eliminating unnecessary downtime

Food manufacturing sites that are highly automated operate with fewer workers, resulting in a larger opportunity for uninterrupted processing. Manufacturers are currently seeking to mitigate the risk of sending people home in virus-susceptible areas within their facilities, and automation is a big part of this solution.

The risk of downtime, as a result of machinery failure, servicing or reprogramming has always been a bottleneck in the adoption of automation.

However, automation specialists have been driving the intelligence of robotic systems forward for some time, and there is now a greater emphasis on linking these systems together and integrating them into a customers’ own specific data network. Consequently, food manufacturers can capture, process, and analyse big data from the factory floor remotely, and improve productivity, avoid downtime through predictive maintenance, upload new case recipes, and optimise energy use.

“Systems built today feature an integrated, Industry 4.0 compatible HMI interface enabling engineers to easily re-programme the machine to allow for new configurations of case sizes remotely via a computer, tablet or even a mobile.”

Beyond Covid-19

Robotics and automation has always been an enabler to streamline and enhance efficiency and, as a result of the pressure created by the crisis on manual process, manufacturers should now be able to clearly identify which areas would benefit from automation.

Covid-19 has undoubtedly heightened the need for the UK to integrate robotics into their packing lines. By taking the steps to automate, manufacturers will be prepared for any future crisis or shutdown, while ensuring that their output levels and efficiencies remain high.

This will also make the UK more competitive on the global production field.

 

Robotic palletising systems increase productivity for Amstel Brewery

As a result of installing three Fanuc industrial robots on the re-packing line within Heineken’s Amstel Brewery, productivity increased up to 21,000 bottles of beer per minute, with a significant reduction in production costs.

While the first robot automatically de-palletises a full plastic crate and positions it onto a crate conveyor system, the second robot automatically removes the bottles from the crates and positions them on the bottles infeed conveyor.

The bottles are then collated and packed into shrink wrapped multipacks. Then an integrated coding system is used to print expiry dates and batch codes on each multipack, while a print and apply system is used to label the packs, before the third robot palletises the re-packed bottles ready for the stretch wrapping systems and, finally, loading for distribution.

The empty crates are returned to the first robot and collated for automatic palletising ahead of being loaded onto lorries and returned to the bottling site.

The system is offering maximum productivity and also a great level of flexibility as it can easily be upgraded and modified to handle new products.
