Full container inspection


HEUFT spotter SF

Inspecting full bottles precisely:  complete inspection without blind spots.

The HEUFT spotter SF identifies low density foreign objects which are floating in the product or have sunk to the bottom such as film remnants, bits of paper, insects and mould in glass and PET bottles filled with transparent liquids just as reliably as scratches, cracks, inclusions, chips, breaks and other material defects.  The optical examination covers the complete container volume and even includes such areas which have been deemed impossible to be inspected until now:  even faults hidden behind the dome or covered by the base edge and other structures are reliably tracked down.



Optical base inspection

Leaving nothing out:  continuous complete inspection of the total container base.

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 reflexx² 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.  Therefore this guarantees, together with the HEUFT reflexx² 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 TX systems with their modular design can be extended at any time.  In this way the range of functions of the HEUFT spotter SF can be optionally expanded with powerful detection units for checking the fill level as well as the closure and label presence.  The HEUFT sonic additional module checks the tightness of metal closures.




Controlling centrally:  one platform for all requirements.

Precise, network-compatible and cross-system:  the HEUFT SPECTRUM TX forms the basis for different technologies, modules and functions.  The devices of the generation of the same name can be exactly adapted to individual requirements on site and retrofitted at any time due to this universal platform.


A cross-system component equality of 70 per cent ensures a high availability of spare parts.  The central HEUFT SPECTRUM TX control unit creates a high level of precision during continuous product tracking and quality assurance due to its multiprocessing capability.  A future-proof network connection ensures reliable remote maintenance and production data acquisition for optimum efficiency and productivity.  In-house developed hardware and software and its own operating system ensure computing power and offer no opportunity for viruses or malware.


HEUFT reflexx²

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 reflexx² 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.



Operating HEUFT systems reliably:  graphical user interface with practical tools.

Clear, helpful and specific:  the HEUFT PILOT graphical user interface convinces due to an easy to understand, multilingual menu structure with extensive auxiliary tools.  Therefore the reliable operation of the HEUFT SPECTRUM TX systems is not difficult.


Important information and clear error messages with service notes provide the respective user with specific support.  This avoids incorrect adjustments and shortens standstills e.g. during brand changes.  Password protected operator levels adapted to the respective area of responsibility also contribute to this.  Also integrated:  a complete online user manual and a tool for the uncomplicated identification and direct ordering of spare parts.



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 faulty full containers.
