Components for reverse vending machines

Our recognition units have been setting standards in terms of performance and reliability for many years. By using multiple cameras, we provide a 360° viewing angle to analyze beverage containers from any angle when they are returned.

Our systems are designed as ready-to-use OEM technology and can therefore be easily integrated into your existing reverse vending machine. This allows reliable detection and evaluation of security signets and barcodes printed on beverage packaging. In this context, we have been supplying the leading manufacturers of reverse vending machines for the retail with our technology for the verification of deposit containers for several years now.

The insensiv recognition units are used in several deposit return systems throughout Europe, for example in Germany and Denmark. For manufacturers of reverse vending machines, we also offer systems for shape analysis and crate recognition.

Manipulation &

In Germany, beverage containers have a deposit value of €0.25. This amount is usually handed out to the customer in the form of a receipt when a empty bottle or can is returned. The receipt can then be redeemed as a discount at the supermarket checkout. This is sufficient incentive for a fraud attempt to illegally obtain the deposit value.

In order to be able to identify deposit containers correctly, bottles and cans are marked with a barcode and usually also with a deposit logo. These security features are analyzed by the insensiv recognition unit when the containers are returned. Due to the high deposit value, reliable recognition rates are required, which can be guaranteed by our systems. In addition, a shape measurement is carried out by our bottle shape recognition systems as part of the return process.

The precise analysis of each single bottle and can, ensures a maximum security of the deposit system. The intelligent image processing technology of our recognition units also detects any form of attempted manipulation, such as the subsequent withdrawal of beverage containers that have already been entered.
