Empty bottle inspection



Your entry to the complete inspection of empty bottles on a HEUFT level.

Genuine high-tech for all:  the long-standing benchmark for a continuous empty bottle inspection on only one square metre of floor space is now available based on the HEUFT SPECTRUM II.  The modular HEUFT InLine II IR achieves an unprecedented level of automation, detection, manipulation and operational reliability and is ideal for craft brewers, wine bottlers as well as other SMEs who have limited space available and high quality standards.  The compact system combines a proven design and sophisticated detection technologies with the performance and self-explanatory user guidance of the new generation.


Optical base inspection

Covering everything: a continuous complete inspection of the whole base.

Film, cigarette ends, insects but also glass splinters and cracks: the HEUFT InLine II IR carries out an optical complete inspection of the bottle base in order to detect foreign objects and defects reliably. An LED illumination without reflections or shadows and specially positioned high-performance cameras even make transparent and reflecting faults visible. The HEUFT reflexx² image processing system combines and analyses the detection pictures in real time and makes a specific teach-in possible. Serious defects and foreign objects on the base of the bottles to be filled are therefore detected in good time and clearly distinguished from harmless aesthetic blemishes.


Extensive finish inspection

Finding finish faults:  safety around the bottle opening.

Defects, cracks, rust rings, contamination and chips on the bottle finish:  the HEUFT InLine II IR carries out an optical inspection of the complete finish and underchip area of each individual empty bottle in order to identify such faults reliably.  The range of functions and the detection accuracy when examining the delicate area around the bottle opening can even be further extended by means of optional add-on modules (see below).  Thus the compact device meets all the safety and quality requirements.


Continuous sidewall inspection

Inspecting all around: no blind spots.

Contamination, defects, cracks or inclusions: anyone wishing to detect such quality flaws reliably cannot afford to do without an all-around inspection. After all the sidewalls of the empty bottles should be covered completely. This is ensured by a harmonious LED illumination which prevents shadows and reflections in the detection pictures on the one hand. Thus the inspection of the complete bottle volume is already achieved in low speed ranges when there is a sufficient gap between the containers with the standard device which is only one metre long. Additional optical modules for a 360° sidewall inspection (see below) can be integrated in the infeed and outfeed of the HEUFT InLine II IR for higher line outputs and even more precision. Each empty bottle is purposefully rotated between the individual detection stations so that it can be continuously examined from all sides. Blind spots in the detection pictures put together by the HEUFT reflexx² are therefore ruled out.


Residual liquid detection

Tracking down lye, oil and varnish: effective protection against product contamination.

Caustic lye, oil or varnish:  even minute amounts of residual liquid seriously threaten the safety of the end product.  The system has two different methods in order to detect and remove the empty bottles in question before the filling process:  it identifies residual lye using high frequency technology (HF) and oil and varnish with infrared technology (IR).  The IR detection, safely enclosed, is directly integrated in the compact device together with its own LED illumination panel.  The HEUFT fluid module for the reliable detection of health hazardous lye remains can be installed easily and using little space directly on the bottle conveyor.  The entry-level device for inspecting empty bottles therefore provides effective protection against product contamination due to harmful residual liquid.


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.  Thus the optionally available colour ring inspection provides even more detection accuracy during the finish inspection.  Even thermal cracks and extremely fine tension cracks in the sealing surface can be reliably detected with it.  In addition a special optical technology for the precise inspection of the inside of the finish can be integrated upon request.  Whether single, double or quadruple sidewall inspection:  there are various options available depending on the performance range and quality requirements.  Even a module for examining the inner bottle walls can be integrated without a problem.  A special scuffing detection for the HEUFT InLine II IR is also available for those filling into returnable bottles.



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 artificial intelligence.

The AI discipline of machine learning for targeted object classification has been mastered by our self-developed image processing since 2010! And since then it has learned a lot: intelligent filters distinguish drops of water on the container from air bubbles in the glass and even make it possible to identify tiny defects which are hidden behind ACLs or embossings. HEUFT reflexx A.I. now also uses deep learning!


Appropriately trained neural networks are used for example to denoise X-ray images or to find dangerous foreign objects in structured products and to reliably distinguish them from good objects which are extremely similar in their shape, size and density. With true artificial intelligence, the hardware and software from our own development and production again increases detection reliability - and minimises the false rejection rate. The smart image processing can be directly integrated into the HEUFT reflexx A.I. camera which was developed in-house and which processes and evaluates its own images directly in real time and raises the adaptive image analysis to a top level.




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 with clearly assignable letters are on the device components where intervention may be required.  If the worst comes to the worst the HEUFT NaVi shows them on the touchscreen.  The HEUFT checkPoints then even optionally flash on the respective component in each case.  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 as well as the multi-segment HEUFT DELTA-FW and HEUFT DELTA-K systems are ideally suited for the reliable rejection of faulty empty bottles.  A total of up to four rejection systems can be connected to the HEUFT InLine II IR.  This also makes a rejection possible which is sorted according to the fault type.
