Foreign object inspection



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

Tracking down solid foreign objects just as easily and precisely as low density contamination:  this is possible with the HEUFT eXaminer II XOS in a very confined space.  For this the compact full container inspector has radiometric as well as optical detection technologies and supports the user step by step using images, text and sound.



X-ray base inspection

Flashing instead of X-raying:  maximum detection performance and minimum emission.

Stones, pieces of metal and glass splinters:  the system identifies these faults on the base of the bottle, which can hardly be seen with the naked eye, using pulsed X-ray technology.  Unique X-ray strobes achieve maximum detection reliability.


In contrast to the conventional X-ray scanner radiation is only emitted at the moment when a product to be examined is in the inspection area.  This minimises the radiation exposure.  Each individual empty container is optimally aligned at several detection stations using servo technology so that the inspection covers the whole base area completely.  The HEUFT reflexx A.I image processing system combines and analyses the detection pictures in real time and implements a specific teaching in procedure.


Optical base inspection

Looking closely:  special optics for difficult cases.

Paper, film and mould:  the system identifies minute low density foreign objects on the base of the full bottle using the HEUFT sinker technology.  Special optics even make transparent and reflective objects visible.


A precise servo-controlled rotation of the containers ensures that these are each optimally aligned at several detection units and that the inspection covers the whole base of the bottle.  Even faults covered by glass marks or embossing cannot escape the examination.  The specially developed evaluation procedures of the HEUFT reflexx A.I real-time image processing system ensure this.



360° sidewall inspection

Not overlooking anything:  safe all around due to optical all-around inspection.

Defects, cracks and floating foreign objects:  the HEUFT floater technology tracks downs such faults at the sidewall and inside the bottle reliably.  A combination of special illumination and camera technologies carries out the precise identification of objects which can hardly be perceived by the naked eye – even transparent and reflective scraps of film are reliably detected in this way.


The servo-controlled alignment of each individual bottle ensures a complete 360° sidewall inspection.  This guarantees, together with the HEUFT reflexx A.I real-time image processing system with teaching in capability, that nothing is overlooked.



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 extended at any time.
In this way the range of functions of the HEUFT eXaminer II XOS can be optionally extended with powerful detection units for checking the fill level and the closure presence.  The HEUFT sonic additional module checks the tightness of metal closures.




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 faulty full containers.
