Optisort Battery Sorter
Automatic sorting of waste portable batteries
Optisort Battery Sorter is a modular sorting equipment, which in one shift automatically can sort between 4 and 8 tonnes of waste portable batteries per day (0,5 to 1 tonne per hour). The equipment can sort all kinds of portable batteries from D to small Lithium and alkaline cells. All chemistries available today can be sorted and it’s also possible to add new sorting fractions, such as different kinds of Lithium batteries.
Vision sensors and artificial intelligence
The identification of every battery is made with a machine vision sensor that captures images of every battery in high speed. The image is then, in milliseconds, comparing the image with previous images taken in a large set of data, using neural networks. The system is self-learning, which enables it to recognize batteries even if they are dirty or damaged.
After classification the batteries are separated with airjets into each respective fractions which allows for high accuracy under high speed.
High purity rate
The purity of the fractions is normally over 98 per cent. However, for chemistries coming in very small volumes manual control may be needed, due to higher relative contamination.
Robust mechanical separation
The line-up and separation of the batteries is made with robust equipment that instead of organizing the batteries in different sizes co-mingle all batteries on one conveyor. That does not only decrease the risk for congestions but also decreases energy consumption and need for space for the equipment.
Besides the actual sorting of batteries Optisort Battery Sorter collects data about all sorted batteries including brand, model, size and chemistry. That means detailed statistics can be extracted from the sorting which then can be used for reports and analysis. For compliance schemes the statistics may be used to find freeriders but potentially also to provide producers with valuable market information. It is also possible to sort out known counterfeit batteries and also to identify new ones.
The standard sorting system can sort 0,5 tonnes per hour which means around 1,000 tonnes a year using one shift. The system can be parallelized with another sorting line which will enable sorting of 2,000 tonnes in one shift. All together the automatic sorting equipment needs 6x4 meters, pre-sorting equipment not taken into account.
