Leakage check


HEUFT squeezer II

Finding leaks and closure faults quite easily:  flexible leakage check based on the highly automated HEUFT SPECTRUM II.

Simply more performance when detecting leaks: the HEUFT squeezer II ensures the microbiological purity of sensitive foods by identifying leaking full containers, made of plastic, in-line and removing them immediately. The optional flexibly extendable inspection path increases accuracy during the detection of minute microleaks. An all-around closure inspection is fully integrated. Its high degree of automation and self-explanatory user guidance make the reliable operation of the leakage check of the new generation 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 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 containers made of PET, HDPE or PE with such faults reliably.


A precisely controlled amount of pressure is exerted on the containers for this.  The internal pressure falls while the fill level rises if there is a leak.  A correlated evaluation of the fill level and internal pressure measurements refine the result.  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 container.  The conveyor belt guiding the containers as well as all the detection units adapt themselves fully automatically to the changed 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 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.


The HEUFT FinalView II CAP for a 360° closure inspection is now directly integrable into the HEUFT squeezer II.From contour and thread inspection to lid logo recognition and the identification of leaking closure foils, defective retaining rings or torn tamper-evident labels, this provides a detailed all-round inspection of the container closures and all their safety elements..



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.



Easy brand changes

Changing automatically: servo-controlled adjustment of the transport and detection units.

Fast, automatic and simple: The new generation leakage check carries out brand and program changes fully automatically: the position of all the detection modules as well as the height and passage width of the servo-controlled belt drive, which is only on one level, adapt to the changed container format automatically. This makes it possible to inspect larger plastic containers and eliminates misadjustments during a brand change due to operating errors. Furthermore human resources are freed up, time and money saved in this way because efficiency and productivity losses due to lengthy changeover times are sustainably reduced.


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. A quantifying pressure analysis converts the results of the individual internal pressure measurements and thus determines the average values of complete batches. Camera, high frequency or X-ray technology is available for the fill level detection as well as special sensory and optical procedures or even ultrasonics for the closure detection depending on the product and the task. The HEUFT squeezer II not only detects filling quantity and closure 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.


ts individually adjustable gooseneck display ensures simply more ergonomics and flexibility during the reliable operation of the HEUFT squeezer II.

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 faulty containers.
