At the end of the production chain ice-cream cones coming from below are brought into horizontal position by 12 vacuum grippers. If the ice-cream or the cone are defective, the vacuum gripper cannot lift the ice-cream. The ice-cream falls into a collecting pan. A sensor must detect this to prevent that an empty film packaging gets into the further packaging process.

Geri dönüşüm
So far, photoelectric sensors used to be installed which could only be positioned underneath the vacuum grippers. Constantly falling cones or pieces of ice-cream caused soiling of the sensors which in turn led to a failure. The efector pmd optical distance sensor from ifm now installed detects the ice-cream cone from a safe distance.

Müşteriye sağladığı yararlar
Due to the long range of efector pmd it could be mounted in a position from where it looks at the ice-cream from the front. Advantage: No crumbs can fall on the sensors and interfere. The sensor also detects if all the ice-cream falls down from the vacuum gripper. Dark surfaces such as a chocolate coating are also reliably detected even against a very shiny stainless steel background. Furthermore "zero fault production" without a waste of resources (film packaging) is achieved. So this investment has paid off after already a very short time.
