Foreign object inspection



Simply detecting more:  full container inspection based on the HEUFT SPECTRUM II.

Foreign objects in containers filled with liquid, paste-like or spreadable food are a real safety risk.  Therefore it is important to track them down whilst still on the production line and to remove the packages in question early enough from the production flow.  The compact HEUFT eXaminer II XAC with the hygiene-friendly HEUFT CleanDesign monitors product safety continuously and identifies minute foreign objects even in opaque products.  The end of line system based on the highly automated HEUFT SPECTRUM II device platform achieves an unequalled performance with sustainably optimised pulsed X-ray technology.  The audiovisual HEUFT NaVi user guidance makes error-free operation simply easy.


X-ray base inspection

Covering everything:  complete inspection of the container base without blind spots.

Glass splinters, small pieces of metal and stones:  the system identifies such foreign objects on the base of the container highly precisely.  A unique combination of X-ray strobes and compact full-field image converters available exclusively from HEUFT increases the range, speed and precision of the inspection.  Even foreign objects close to the base curvature are identified reliably.  Blind spots are ruled out.


The double base inspection with specially arranged detection units in conjunction with the HEUFT reflexxA.I real-time image processing system ensures this.  The X-ray parameters adapted to the full-field image converters reduce the already unequalled low radiation.  In contrast to the conventional X-ray scanner it is only emitted at the moment when a product to be examined is in the inspection area.


Sidewall inspection

A complete examination:  double X-ray inspection.

Thick, paste-like and spreadable:  dangerous foreign objects often float around in jars or cans of food with such contents.  The end of line system carries out a double sidewall inspection which covers the complete container volume in order to detect these reliably.


The combination of precisely positioned X-ray strobes, full-field image converters and powerful image processing system also achieves an unprecedented range and precision with minimum radiation exposure in this case.  Even oversized food packaging made of glass, plastic and metal can therefore be examined continuously.


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

Detecting even more:  extensions to the range of functions.

The HEUFT SPECTRUM II systems with their modular design can be expanded at any time.  Therefore the range of functions of the HEUFT eXaminer II XAC can be extended, for example, with powerful detection units for precisely checking the filling quantity.



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 individual teaching in procedure.

Fast, high-resolution and smart:  the new generation of in-house developed hardware and software for image processing provides four times the processor speed of its predecessor.  It converts the images of the individual camera or X-ray units into high-resolution, noiseless detection pictures in real time.


At the same time the HEUFT reflexx A.I. not only carries out the specific detection of the most varied objects but also their individual classification using up to 50 different characteristics such as size or texture:  uncritical characteristics can be quite simply taught in as good objects.  The containers in question are therefore no longer rejected.  Only that which really has to be removed is rejected.  This reduces the false rejection rate and upholds the efficiency and productivity of the complete filling line.




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 CleanDesign

Cleaning quite simply:  hygiene-optimised construction.

Accessible, clean and safe:  its HEUFT CleanDesign predestines the system for use in hygienically sensitive areas.


Sloping surfaces facilitate cleaning and prevent the accumulation of stubborn dirt.  Special channels and openings allow the liquids required for cleaning purposes to be drained off completely.  Consequently dangerous germs and bacteria have no contact surface whatsoever.  Specially constructed casings and doors create optimum accessibility.  The electronics are totally encapsulated.  Sensitive areas such as the inspection units are dust-proof and protected against contact as well as water jets.


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.
