Leakage check


HEUFT squeezer II QS

Finding leaks and closure faults quite easily:  fully automatic leakage check based on the HEUFT SPECTRUM II.

Simply more performance when detecting minute leaks:  the HEUFT squeezer II QS ensures the microbiological purity of sensitive drinks by identifying leaking PET bottles in-line and removing them immediately.  The system adapts itself independently to the changed container shape for a fast brand change.  The high degree of automation of the HEUFT SPECTRUM II device platform and the self-explanatory HEUFT NaVi user guidance make the reliable operation of the leakage check simply easy.


Leakage check

Finding leaks reliably:  a comparative fill level detection and measurement of the internal pressure.

Leaks, stress cracks and microcracks:  the HEUFT squeezer II QS measures the internal pressure on the one hand and in addition carries out a comparative fill level detection in a compressed and non-compressed condition in order to find filled PET bottles with such faults reliably.


A precisely controlled amount of pressure is exerted on the containers for this.  The internal pressure is lower while the fill level rises if there is a leak.  Even the smallest leaks are reliably tracked down in this way.  This safeguards the integrity of the product as well as the stability and steadiness of the bottle.  The conveyor belt guiding the containers as well as all the detection units adapt themselves fully automatically to the changed bottle format for fast, fully automatic brand changes.



Closure detection

Ensuring tightness:  different possibilities for checking the closures.

Missing, canted and defective:  closure faults such as these threaten the tightness of the drinks packaging in the same way as the quality of its contents.  Different technologies for a closure detection can be integrated into the system in order to uncover them reliably.


It can check the presence, position, completeness, integrity and brand affiliation of the closures precisely with special sensor, camera or ultrasonic technology depending on the requirements.  Thus the HEUFT squeezer II QS provides the best results for every application and safeguards the tightness of the bottle sustainably as well as the quality of the product contained in it.



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.  Camera, high frequency or X-ray technology is available for the fill level detection depending on the product and the task.


The HEUFT VISION 360 module carries out a high-precision optical closure inspection as an option.  The HEUFT squeezer II QS not only finds such faults but also locates their causes in good time if required:  it continuously monitors the performance of each individual filler valve and closer head for this and evaluates them statistically.  Malfunctions which can cause serial faults are therefore identified in good time.  This monitoring process exposes defective valves and closer heads before they fail completely.  This makes it a valuable tool for preventive maintenance.




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 single-segment HEUFT mono rejector and the multi-segment HEUFT DELTA-FW and HEUFT DELTA-K systems are ideally suited for the reliable rejection of full bottles made of PET.
