The automated operation of the robotic arms is regulated by a compact MELSEC-Q series high-performance PLC designed for small-scale applications. The PLC then acts as an intermediary between the robots and a GOT2000 HMI, which enables human operators to easily set what type of cutting is required and monitor the process.
The machine can cut substances with different consistencies packed in various food tray shapes and sizes without requiring any hardware modifications. In fact, all these cases are characterised by distinctive cutting needs. For example, chilled goods would require a slower cutting speed compared to softer foods. Similarly, chopping orientations and angles for round products, such as pizza, differ from rectangular tray bake products like flapjacks.
Going ultrasonic
Ultrasonic blades can cut different materials quickly, with high accuracy and by applying very low pressures. When compared to conventional blades, the number of crumbs and waste produced is considerably lower, especially when cutting near the edges of the material. Even more, when faced with variable ingredients and toppings, such as cherries in a cake, these are sliced without squeezing them or damaging the whole product, ensuring an aesthetically pleasing result.
Telsonic adds: "The ultrasonic blades used in this application are 760 mm long, which makes them the largest available on the market. This not only results in faster cycle times, but also higher quality. When slicing large trays, fewer cuts on the same axis are required, minimising the risk of misalignment. The ability to self-clean and maintain a sharp blade, further streamline the process."
