Empty bottle inspection



Detecting everything and changing automatically:  brand changes at the touch of a button during the inspection of empty bottles.

The HEUFT InLine IS achieves highest precision during the continuous all-around inspection of empty bottles.  The compact system is equipped with powerful detection modules for this.  The integrated servo technology carries out an exact fine adjustment of the bottles for a continuous all-around inspection and automatic brand and format changes. 


Optical base inspection

Covering everything:  continuous complete inspection of the total container base.

Film, cigarette ends and insects:  the system carries out an optical base inspection in order to detect such low density foreign objects reliably.  An illumination without reflections or shadows and specially positioned high-performance cameras even make transparent and reflecting faults visible.  Each individual empty container is optimally aligned using servo technology so that the inspection covers the whole base area completely.  The HEUFT reflexx image processing system combines and analyses the detection pictures in real time.


Finish and thread inspection

Finding defects and cracks:  safety around the bottle opening.

Defects, cracks, rust rings, dirt on the bottle finish and defects on the thread:  the system has an ingenious technology for an optical finish and thread inspection in order to find such faults before they can endanger product safety.  It not only covers the complete sealing surface but also the whole underchip / thread area.


360° sidewall inspection

Inspecting all around:  a continuous complete examination.

Dirt, defects, cracks or scuffing:  anyone wishing to detect such quality flaws reliably cannot afford to ignore an all-around inspection.  After all the sidewalls of the empty bottles should be covered completely.  This is possible using servo technology for specifically aligning the containers, an illumination without reflections or shadows and specially positioned high-performance cameras.


The HEUFT reflexx image processing system combines and analyses the detection pictures in real time.  In addition it clearly differentiates between integrated container structures and actual faults.



Residual liquid detection

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

Caustic lye, oil or varnish:  even minute amounts of such residual liquids 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 and oil and varnish with infrared sensors.


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 change

Changing automatically:  servo-controlled adjustment of the conveyor belt.

The HEUFT InLine IS not only carries out a specific rotation and an exact alignment of the bottles with innovative servo technology for an optimal complete inspection.  In addition it adapts the height and width of the conveyor belt exactly to the changed bottle format during brand changes.


This is achieved completely automatically due to clearly reproducible brand adjustments.  This reduces the need for manual intervention, economizes on human resources and not only saves time but money as well:  efficiency and productivity losses due to lengthy changeover times are sustainably decreased.


Optional additional functions

Detecting even more:  extensions to the range of functions.

The HEUFT SPECTRUM systems with their modular design can be extended at any time.  Thus the optionally available colour ring inspection provides even more detection accuracy during the finish inspection.  Even thermal cracks, tension cracks and other faults without the loss of material are detected reliably.  In addition a special optical technology for the precise inspection of the inside of the finish is available upon request.



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 reflexx

Combining photographs and reliably detecting objects:  image processing in real time.

Fast, powerful and exact:  combining several camera and X-ray images with each other and specifically detecting various objects.  The HEUFT reflexx carries out all this in real time.


The in-house developed hardware and software provides high computing capacity and is exactly tailored to the requirements of the in-line quality inspection.  It generates high-resolution, noiseless detection pictures and analyses them precisely.  Integrated filter technologies clearly differentiate between supposed and actual faults.  This reduces the false rejection rate sustainably.



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 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.
