Ultrasonic sensors assist in packing of fresh flowers
Fresh cut flowers that are shipped internationally in large quantities, must be fresh, but still efficiently processed and packaged very gently. In this flower-packing machine it has to be detected when a bunch of flowers is ready in the tub for packing. An ultrasonic sensor of the UPR series (see circle) looks down from above on the flowers and outputs a “present / not present” signal. The ultrasonic sensor was chosen because it is able to detect the very different shapes, colors and textures of the flowers reliably.
