Sustainability at the touch of a button with the e-chain in Drop Water beverage vending machines

The new miniature filling system from California uses igus motion plastics to reduce transport and the use of plastic bottles.

The Drop Station is a new sustainable beverage vending machine that fills compostable containers with customised beverages at the touch of a button. The water for the vending machine does not need to be transported, since the kiosk can be connected to a water source on site. A linear robot with drylin linear guides mixes the beverages and dispenses them. The igus harnessed e-chains, which are available from Treotham Automation ensure protection for the chainflex energy and data cables.

You can find them in airports, supermarkets and train stations: beverage vending machines from Drop Water, based in California. Customers can use a touch display to select a beverage from the Drop Station. They then receive an individually filled, compostable container filled with tap water filtered at the point of sale and, according to the customer’s wishes, may contain caffeine or be flavoured or heated or cooled to a certain temperature. The new vending machine allows Drop Water to decentralise the process of bottle filling by having the self-service kiosk function as a miniature filling system. The company’s approach is much more environmentally friendly than that of conventional providers of bottled water. It eliminates the need for transporting filled bottles. “The Drop Container is a large part of what makes our kiosks unique. Each Drop Station has a supply of empty, compostable containers that can be refilled as necessary. The customer can also use their own bottles”, says Scott Edwards, CEO of Drop Water. The heart of the vending machine is a linear robot that manufactures and dispenses beverages. It is also supplied with energy and data. Although an energy chain was used, there were cable failures in the prototypes. It was found that the cables rotated slowly during each cycle, so they were twisted after 1,000 cycles. A second problem was harnessing. In order to avoid having to continually buy, cut, modify and assemble every single component, the company needed a functioning, ready-to-connect solution.

Looking for a better system
Thanks to the right interior separation and a fully harnessed readychain igus e-chain system, the vending machine now functions perfectly. This saves the company a great deal of installation time and costs. Drop Water also turned to igus for the linear robot and the output unit. The mechanical system consists of maintenance-free drylin W and drylin N rails and carriages. “We are proud to work with a forward-looking, socially responsible company like Drop Water, and we wish them many years of success as we contribute to all the movements that will keep our planet clean and free from pollution for the generations to come”, says Rick Abbate, Vice President of igus Inc. USA. The project convinced the judges for the seventh vector awards. The prize is awarded once every two years and distinguishes creative energy chain applications from all over the world. Drop Water received the green vector award, which was awarded to two sustainable projects for the first time.
