HEUFT SX

Sorting out non-brand bottles:  a homogeneous supply of empties.

One factor is decisive for the efficiency of returnable filling lines:  that only that enters which is allowed to.  The efficiency of the complete line is impaired if there is a mixed supply of empty glass / PET bottles.  The HEUFT SX puts things right.  The bottle sorting unit examines returnable containers closely and only allows those to flow into production which should be there.

Checking the format

Uncovering deviations:  examining the bottle shape.

Too tall, too short or with a different shape:  the HEUFT SX checks the container dimensions and removes bottles with deviating formats reliably.

It generates a shadow picture of each bottle which passes through during an interaction of ingenious illumination, camera and image processing technologies.  It is identified as being non-brand if its height or shape deviates from the reference sample stored in the system.  Other types of container structures such as indentations or applied colour labels are also reliably detected using the same procedure.

Brightness and colour detection

Keeping track:  tracking down bottles with the incorrect colour.

Too light, too dark and of the wrong colour:  the empties sorting unit checks the brightness and the colour of the bottles with optical technologies.  For this a reference container has to show its colours first – the desired colour is adjusted using this.

The results of the empty bottles to be inspected are compared to these reference values.  There is a high probability that the bottle is good if the brightness and colour correspond to the reference values.  Possible variations in the colour are automatically compensated for in the case of this assessment.  The HEUFT SX even identifies differences such as the UV coating of clear glass bottles which cannot be seen with the naked eye reliably.

Closure and finish check

Sorting out sealed empty bottles and those which cannot be sealed:  examining the bottle opening.

Sealed, misshapen and unsuitable:  empty bottles must not be sealed in order to be able to clean, refill and reliably seal them.  Furthermore the finish must be in good shape.  Otherwise the efficiency of the complete line will suffer.  The HEUFT SX examines the finish area on the conveyor in order to detect such faults early enough.

Sealed containers are identified reliably using a special optical procedure.  The above-mentioned shadow picture technology makes deviations to the finish shape visible.  Therefore bottles which cannot be filled or sealed are identified and sorted out in good time.  This has a positive effect not only on the quality of the final product but also on the efficiency and productivity of the complete filling line.

 

Differentiating between glass and PET

Preventing a mixed assortment:  checking the material properties.

Simple, clear and reliable:  the HEUFT SX checks the bottle material and clearly differentiates between glass and plastic – entirely without the complex use of X-ray or gamma radiation.

Instead the empties sorting unit makes use of the different optical properties of the materials in order to strictly differentiate between them.  Even variations in colour and thickness cannot mar the detection reliability in the course of this:  glass is always identified as glass – a mix-up with PET is out of the question.  The result:  real brand purity – only bottles made of the correct material enter the filling line.

 

Combined evaluation of all the measuring results

Calculating the total probability:  analysis by means of fuzzy logic.

Combining, comparing and judging:  different measuring procedures only produce an optimal result when they are linked with each other.  After all not all the bottles should be sorted out.  Even those with inconclusive, borderline properties can indeed be the correct ones.

That is why the fuzzy logic calculates the probability of the individual values determined with regard to brand affiliation and combines them via a complex algorithm into the total probability.  Therefore empty bottles of the correct brand with negligible deviations do not have to be sorted out.  This has a positive effect on the efficiency and productivity of the complete line for returnables.

 

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.

 

 

HEUFT SPECTRUM TX

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.

 

HEUFT PILOT

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.

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.
