For image acquisition by the camera, this uses an ultrasonic probe with beam narrowing or a special reflex photocell with fine-tripel reflector for the detection of transparent objects.
The camera itself here consists of a monochrome smart camera in combination with a diffuse backlight with which, in addition to checking the brightness of the product, the contour of the bottle and the screw thread can be properly measured. The top ring can also be checked here to ensure that it is complete and the correct diameter.
Depending on the production line, the speeds on the conveyor belt can vary and speeds of 300 bottles per minute are still possible. If a faulty product is detected, it is immediately blown out by the smart camera even before the next bottle is in front of the camera. As soon as X number of bottles in a row are faulty, an alarm can be triggered to alert an operator or stop the production line.
