Empty can inspection


HEUFT canLine

Empty cans in top form:  safety and efficiency when filling cans.


Detecting faulty empty cans and removing them before they can thwart the productivity of the filling line and present a threat to the health of the consumer:  this is definitely achieved with the HEUFT canLine.  The empty can inspector only allows those drinks cans to pass which are clean, undamaged and uncontaminated and can be filled and sealed perfectly and without a problem.


Optical top-down inspection

Finding deformations and damage early enough:  reliability and efficiency on the canning line.

Deformed, distorted and damaged:  such empty cans can cause obstructions in the filler / closer system and paralyse the efficiency and productivity of the complete line if they are not rejected in good time.  The HEUFT canLine prevents this.  It removes distorted containers just as reliably as empty cans with indentations and defects at the flanged edge.


In addition the compact system identifies foreign objects and contaminants on the inner wall and the base of the cans – using a powerful top-down camera and an illumination free of shadows and reflections.  The HEUFT reflexx2 image processing system analyses the detection pictures in real time and implements a specific teaching in procedure for maximum detection reliability with a minimum false rejection rate.



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:  brand changes at the push of a button.

Brand and format changes are the order of the day along canning lines.  The height and position of the detection units as well as the passage width of the guide rails in the inspection area of the HEUFT canLine automatically adapt themselves to the changed container shape so that they can be carried out quickly, easily and without errors.  All the brand adjustments are permanently stored in the system and can be reproduced at any time.

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 range of functions of the HEUFT canLine can be optionally expanded with a detection unit for an optical 360° inspection of the outer walls.  In this way scratched, misprinted and non-brand cans can be tracked down and sorted out even before they are filled.  The high-performance image processing system with teaching in capability remembers individual quality requirements in the course of this.  This ensures that only those cans reach the market which have a perfect appearance and have been filled with the correct brand.



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 reflexx²

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 reflexx² 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.



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 rejector

Removing faulty products:  the right rejector for all cases.

The HEUFT pusher rejection system is ideally suited for the reliable rejection of faulty empty cans even in the high-speed section.
