Empty crate inspection



Examining the crate design specifically:  sidewall inspection capable of learning.

The HEUFT LKX inspects all four outer walls of empty bottle crates completely and uncovers damage as well as differences in design consistently immediately after the unpacker.  It remembers individual quality requirements in the course of this.  Therefore only crates which meet these exactly reach the point of sale (POS).


Extensive sidewall inspection

Detecting defects and design faults:  complete inspection of the outer walls.

Damage, dirt and design faults:  the HEUFT LKX finds them!  The empty crate inspector generates high-resolution, undistorted colour photographs which display all four crate walls completely using the most modern camera technology and real-time image processing for this.  This makes the inspection continuous.


Therefore deviations cannot escape it – regardless of whether non-brand colours, faulty logos, unreadable lettering, dirt, cracks, scratches, label remnants or damaged recessed grips.



Teaching In

Characterising identified objects alone:  specific implementation of individual quality requirements.

Good, acceptable and unacceptable:  the HEUFT LKX leaves it up to the user himself to characterise the deviations to the crate walls which have been identified.  He can decide whether it is an acceptable anomaly or an unwanted fault.


The HEUFT reflexx A.I real-time image processing system determines deviating objects using different features such as their size and texture and clearly marks these on the detection picture.  The user can specifically select them and clearly characterise them by simply tapping the touchscreen with his finger.  The system remembers these specific quality requirements.  Empty crates which do not meet these are rejected just as consistently as those with critical faults.  It usually suffices to send between 20 and 30 empty crates into the HEUFT LKX in order to determine between 100 and 150 different good and faulty objects.


The rejection of faults

Preventing recalls:  the reliable rejection of faulty crates.

Fast, careful and accurate:  highest precision when detecting faults is only effective if the products in question are also removed afterwards.  The device either emits a conveyor stop signal or activates the corresponding rejection system, such as the HEUFT xcase, in order to remove faulty crates from the production flow.

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.


Simple brand changes

Changing automatically:  automatic adjustment of the detection units.

Reliable, uncomplicated and easy:  the HEUFT LKX carries out brand changes without manual intervention.  All the parameters are adapted automatically and the height and position of the detection units adjusted by motor.  This practically rules out misadjustments saving valuable time and money.




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 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.




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.


Removing faulty cases:

the right rejector for all cases.

Discharging, rejecting and distributing:  HEUFT rejection systems for packaging remove faulty crates, cardboard boxes, trays or shrink wrap packages reliably from the production flow.  They achieve maximum performance optimally matched to their respective task with regard to precision and carefulness.
