NEWS News from UKIVA


By Allan Anderson, UKIVA chairman


As the second wave of coronavirus gathers pace across the UK and much of Europe, there has been a focus across industry on replicating activities that proved to be successful during the initial stages of the pandemic. There are lots of vision


systems already installed that have helped support companies in many industries through the first wave. Looking at some of these success stories serves to highlight some of the reasons why greater adoption of vision technology brings increased automation and improved productivity, and helps mitigate some of the economic effects of Covid-19. For example, a large


parcel courier company, which has experienced very high throughput thanks to increased online shopping


during lockdown, is using 2D and 3D vision systems to make sure its sorting systems can run for longer and with minimal maintenance. This was especially useful with reduced engineering workforce availability. The vision systems check various mechanical operational parameters on the conveyor- based sorting machines to ensure smooth running of the trays used to sort parcels for delivery. This means areas that could otherwise be problematic can be identified before they cause the system to go down. Remote access is another important facet of many vision systems. In the food industry, label inspection systems have allowed a food company to continue providing safely packaged food during lockdown. With increased demand, remote support features have allowed the customer to install additional machines themselves without requiring external engineers to visit the site. In another example, remote support allowed a fault to be rectified on a 3D vision system used to depalletise


‘There has been a demand for vision systems fuelled by the pandemic’


two-metre high pallets of tea at one of the UK’s biggest tea-producers, again without a site visit. The hard drive on the PC was fixed and the software reinstalled to ensure tea production was virtually uninterrupted. There has also been a demand for vision solutions fuelled by the pandemic, some of which has been addressed quickly and some a little longer-term. Perhaps the most direct of these has been for automatic thermal imaging-based camera


systems for detecting people with elevated ‘fever-like’ body temperatures, as part of screening procedures for Covid-19. Infrared temperature measurement at the medial canthus (tear duct) is generally accepted as offering the closest correlation to the core body temperature. In the agri-food industry there has also been growing interest in systems to help with post- harvest vegetable processing, driven by the fact that, in traditional methods, the low skilled labour force works in close proximity. If they fall ill, the harvest is under threat. The hope that economies


across the world can be kept open by avoiding complete lockdowns means that the vision industry is less likely to experience supply chain difficulties than before. In addition, more companies have streamlined their workforce and embraced new ways of doing business, so should be more sustainable through a second wave. Thanks are due to UKIVA members Acrovision, JentonDimaco, Scorpion Vision, and Sick UK for helpful discussions on this subject.
