Counting of Objects in Automatic Deposit Return Machines with Ultrasonic Distance Sensor
In deposit return machines, a check must be carried out to determine how many bottles, cans and containers have been inserted in order to control the capacity of the system. For this purpose, an ultrasonic distance sensor is installed above the belt, which detects in reflex mode the objects made of glass, aluminum or PET regardless of their shape, color, position, surface and size. The background is completely hidden from view. Thanks to the wide sonic cone, moving and jumping objects are also reliably detected with the dirt-resistant sensors.
