Sensors for the future

Hauni’s modular sensor concepts are a departure from previous technologies that required unique sensors to be developed for each machine. The new approach improves in both quality and flexibility.

ICPS can be easily adapted to the required specifications. It assures quality by testing and accurately rejecting incorrect intermediate and end products.

With its new sensor concepts, Hauni enables a machine’s sensor technology to be modified and extended at any time. Moreover, these changes are much simpler to implement than with conventional machine-specific solutions. The demands of continuously accelerating product development cycles mean that the tobacco industry needs flexible solutions more than ever before. After all, when configuring a new maker, it is often difficult for the manufacturer to predict what its machine will be producing in a few years’ time.

One thing that is certain, however, is that the sensors of today and tomorrow will continue to play a key role in boosting product quality and optimizing production. "Modular concepts are the solution," says Niels Ruge, Group Manager Sensors & AREO at Hauni Engineering, with conviction. "With sensor concepts, such as EYEPORT and ICPS, we are investing in modular sensor technologies that can be used in many different Hauni makers and adapted to new requirements extremely quickly."


Flexible system for optical fault detection


The successful ICPS sensor range is one of two modular systems that Hauni has been using for the past two years. The Image Capturing and Processing System is based on high-resolution cameras and is the world’s first series solution to offer 100 percent secure optical online monitoring of this kind. "This is particularly relevant in the growth areas of special filters and THP products," explains Ruge. "The ICPS cameras are not only able to continuously inspect sheet materials, such as sheet tobacco and filter or cigarette paper, for defects. They can also provide optical monitoring of the front surfaces of filter rods or cigarettes at a speed of up to 10,000 pieces per minute – and up to 20,000 pieces with two-lane cigarette machines, such as the PROTOS-M8." The basic system can be modified using a variety of cameras that are easy to exchange. The sensor is placed either in the front area of the machine for material inspection or at the end to monitor the quality of the finished product. Since ICPS is fully integrated into the machine, the system also allows individual products to be ejected. So far, Hauni has sold more than 100 of these sensor systems, which are suitable for use with the KDF-M, KDF 6LEAD, PROTOS 90E/ER and customer-specific THP solutions, to customers all over the world.

Universal sensor concepts reduce the costs for spare parts and training.

EYEPORT is a flexible, modular rod sensor system. It enhances product quality and production flexibility in cigarette and filter makers.

Prepared for new test methods


The same applies to EYEPORT, the flexibly configurable measuring system launched in 2016. This universal rod sensor system provides a wide variety of measurements immediately before the tobacco or filter rods are cut. "EYEPORT is already available for use with the first and second generations of the PROTOS-M as well as the KDF 5 and 6 – including the KDF-M multifilter maker and PROTOS 90E. And we are constantly working to extend its use to other machines," says Ruge. "EYEPORT offers everything we need to respond flexibly to our customers’ wishes. As well as standard functions, such as optimized weight and diameter measurement, we have already integrated new functions, such as capsule measurement in filter production and optical surface inspection (ORIS). The system’s modular design dramatically reduces the product time-to-market required for new measurement functions."
