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.

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.

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.

 

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.
