Foreign object inspection


HEUFT eXaminer II XS

Detecting everything where space is limited: a compact foreign object detection with pulsed X-ray technology based on the HEUFT HEUFT SPECTRUM II.

The space-saving integration of the X-ray technology exclusively available from HEUFT in order to examine freshly filled squeeze bottles, composite packaging, food cans or stand-up pouches continuously, carefully and highly precisely for dangerous foreign objects:  the particularly compact HEUFT eXaminer II XS stand-alone system makes this possible!


Sidewall inspection without blind spots

Examining continuously:  double X-ray pulse for full coverage.

Metal particles, stones and fragments made of hard plastic:  high density foreign objects such as these threaten food safety.  Whether they are hidden on the flat base of the packaging material or in the difficult to inspect area around the fill line:  the particularly space-saving HEUFT eXaminer II XS simply finds them everywhere!  Two optimally positioned X-ray strobes safely enclosed in an extremely compact casing carry out the sidewall inspection for this directly at the conveyor.  It covers the total volume of the full containers standing on the conveyor completely.  An X-ray strobe illuminates these for this purpose from the base to the middle at an angle from below.  The second module covers the rest by emitting its X-ray pulses directly horizontally so that even minute contaminants around the fill line become visible and at the same time an initial fill level detection can be carried out.  Deviations to the packaging shape such as thickness variations in the base are determined, measured and dynamically compensated in real time when processing the X-ray images.  The double sidewall inspection with the pulsed X-ray technology exclusively available from HEUFT thus achieves maximum detection reliability even in such cases.

Fault rejection

Preventing recalls:  the reliable rejection of faulty containers.

Fast, careful and accurate:  highest precision when detecting faults is only effective if the products in question are also removed afterwards.  The single-segment and multi-segment rejection systems of the HEUFT rejector series deal with this both precisely and carefully.

Product monitoring and self-tests

Playing it safe:  exact product tracking and regular self-tests.

Always knowing the current location of a particular product:  each one is tracked precisely for this.  This ensures that none remain uninspected.


The integrated reject verification checks that each product identified as faulty is really removed.  Standard test programs guarantee a regular examination of the detection performance.  Network-based continuous documenting and long-term archiving of the results.


Optional additional functions

Simply detecting more: extensions to the range of functions.

The HEUFT SPECTRUM II systems with their modular design can be expanded at any time.  The compact HEUFT eXaminer II XS is also based on the universal device platform of the new generation.  The HEUFT SPECTRUM II control terminal with unique machine human interface which can be flexibly positioned at the conveyor takes up even less space than the safely enclosed X-ray strobes.  Furthermore other valuable detection functions can be easily integrated:  for example it can then carry out another fill level detection, measure the internal container pressure, check the presence of closure and label or even read and verify product markings in addition to a reliable foreign object detection.  Thus a wide range of safety and quality defects are identified reliably and the containers in question removed consistently in one and the same work process.


Lifetime-optimised pulsed X-ray

Simply better and more sustainable detecting: Unique technology with extended reliability.

More precise, gentler, more durable: what makes the HEUFT X-ray systems so unique is above all the pulsed X-ray technology which is exclusively available from us. Instead of an uninterrupted continuous beam only a short X-ray pulse of a millisecond is emitted. And only at the moment when a product to be examined for dangerous foreign bodies and other safety risks is actually in the detection area. Even if the line speeds are extremely high or fluctuate, full detection reliability is achieved with unrivalled low radiation. The specially developed X-ray tube and other sustainably optimised components not only increase the coverage and sensitivity of radiometric inspection. The same applies to reliability and lifetime, so that the Total Cost of Ownership (TCO) is significantly reduced.



Long before individual X-ray components can lose performance or fail, users are also informed in good time so that they still have enough time for preventive maintenance. Filaments are even integrated redundantly: if one should fail, the other takes over immediately and fully automatically, so that production can continue without interruption. Furthermore novel full-field image converters for which HEUFT can now guarantee a lifetime of eight years* within the framework of an existing maintenance contract and a free replacement within this period in the case of a defect ensure considerably more sensitivity, availability and operational reliability with a reduced TCO.








Simply automating:  universal device platform for maximum performance.

Highly automated, universal and powerful:  the HEUFT SPECTRUM II ensures optimum detection and operational reliability during an in-line quality assurance for the sustainable safeguarding of product quality and line efficiency.


The cross-system control unit with multiprocessing capability for different modules, systems and applications convinces due to its exceptional degree of automation.  Brand and format changes can be carried out without manual intervention.  The unique human machine interface of the universal device platform is self-explanatory.  Human resources are effectively saved in this way.  In-house developed hardware and software of the latest generation and a future-proof network connection achieve highest computing power and data transmission in real time.  The result:  maximum precision during purposeful product tracking, inspection and rejection.



HEUFT reflexx A.I.

Simply detecting more:  real-time image processing with artificial intelligence.

The AI discipline of machine learning for targeted object classification has been mastered by our self-developed image processing since 2010! And since then it has learned a lot: intelligent filters distinguish drops of water on the container from air bubbles in the glass and even make it possible to identify tiny defects which are hidden behind ACLs or embossings. HEUFT reflexx A.I. now also uses deep learning!


Appropriately trained neural networks are used for example to denoise X-ray images or to find dangerous foreign objects in structured products and to reliably distinguish them from good objects which are extremely similar in their shape, size and density. With true artificial intelligence, the hardware and software from our own development and production again increases detection reliability - and minimises the false rejection rate. The smart image processing can be directly integrated into the HEUFT reflexx A.I. camera which was developed in-house and which processes and evaluates its own images directly in real time and raises the adaptive image analysis to a top level.




Simply knowing what to do:  self-explanatory audiovisual user guidance.

Intuitive, individual and audiovisual:  previous knowledge is not required in order to operate the HEUFT SPECTRUM II systems reliably.  The HEUFT NaVi user guidance is self-explanatory and supports the respective user step by step.


An RFID login with user-related access rights provides an overview and makes the respective user's work simply easy:  he only sees what he really needs to on the clearly arranged touchscreen user interface with a flat menu structure, integrated tutorials and precise auxiliary tools in order to fulfil his specific tasks optimally.  He is supported by a virtual assistant in the course of this.  She speaks to him and clearly explains what has to be done when and where.  Purposeful and focussed on the essentials – the audiovisual HEUFT NaVi user guidance makes the reliable operation of HEUFT systems simply easy!



HEUFT checkPoints

Simply seeing where what has to be done:  trouble-free localisation.

Clear, direct and purposeful:  the user can cope immediately on the rare occasions when manual intervention is needed.  Because eye-catching HEUFT checkPoints make it clear at a glance exactly when it is necessary to take matters in hand in addition to the audiovisual information which the HEUFT NaVi provides.


The orange tags not only flash on the touchscreen but also at the respective component if the worst comes to the worst.  The problem is located without a long search.  This saves time and human resources, shortens standstills and therefore increases productivity.


Network technologies

Networking everything:  online connection for increased efficiency and quality.

Information transmission in real time, production data acquisition, line analysis and remote maintenance:  networking is the answer!


HEUFT systems have future-proof network interfaces (Gigabit Ethernet and TCP / IP) for an online connection via the Internet and the database interface (SQL / DDE) for top line efficiency and an optimum quality management with considerably faster and easier workflows.  Therefore production data, shift records, productivity faults and HACCP limit value analyses are available network-wide.  The result:  early identification of quality and efficiency problems.  The firewall protected direct connection to the HEUFT TeleService makes competent remote maintenance possible all around the clock.


HEUFT rejector

Removing faulty products:  the right rejector for all cases.

For example, the compact single-segment HEUFT flip and HEUFT mono systems as well as the multi-segment HEUFT DELTA-K and HEUFT DELTA-FW rejectors are ideally suited for the reliable rejection of full containers contaminated with foreign objects.
