HEUFT InLine II IS

Making premium standard:  genuine high-tech for a continuous empty bottle inspection.

Highly automated, powerful and operationally reliable:  the HEUFT InLine II IS is the new standard for the complete inspection of empty bottles.  The best of the HEUFT InLine II IXS premium device has been transferred to a system of the next generation with a completely new compact construction which has been optimised regarding hygiene and maintenance for this purpose.  The result:  a powerful, comprehensively equipped and easy to operate empty bottle inspector which achieves new levels and defines the state of technological development.  Premium becomes standard!

Infeed check

Ensuring brand purity: infeed check for pre-sorting.

Defective, deviating and non-brand:  the HEUFT InLine II IS can be equipped with different technologies for an infeed check including rejection system so that such bottles cannot enter in the first place and impair the performance of the inspection and the complete filling line.  Therefore specific pre-sorting is achieved before the actual empty bottle inspection for a homogeneous supply:  only suitable empty containers which can be inspected and filled without a problem pass through.  This not only safeguards the production quality but at the same time the efficiency and productivity of the complete line too.

Optical base inspection

Covering everything:  reliable detection of safety risks on the base of the empty bottle.

Film, cigarette ends and insects:  the system carries out an optical base inspection in order to detect such low density foreign objects reliably.  Hundreds of specially arrange LEDs which can be flexibly controlled ensure a homogeneous illumination of the complete base area from the centre to the outer edge for each bottle brand. Thus cleverly positioned high-performance cameras even make transparent and reflecting faults visible – regardless of their respective position. But glass splinters, chips and cracks can also be clearly identified during the continuous examination of the complete bottle base.  The HEUFT reflexx² image processing system combines and analyses the detection pictures in real time and implements a specific teach-in.

Finish and thread inspection

Finding defects and cracks: safety around the bottle opening.

Defects, cracks, rust rings, contamination on the bottle finish and defects in the thread:  the system has ingenious technologies 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 below.  Innovative LED illumination and camera technologies carry out a further improved sealing surface inspection:  the integrated colour ring inspection even makes thermal cracks, tension cracks and other faults without material loss visible.  The precision with which contamination and defects are detected below it as well as in the inner area of the finish and in the thread turns is extremely high.  This safeguards the integrity of the area around the bottle opening just as the sealability of the empty bottle to be filled.

360° sidewall inspection

Inspecting all around:  a continuous complete examination.

Contamination, defects, inclusions or cracks:  anyone wishing to detect such quality flaws reliably cannot afford to do without an all-around inspection.  After all the sidewalls of the empty bottles should be covered completely.  The HEUFT InLine II IS carries this out using a maximum of two optical quadruple sidewall inspection modules with doubled resolution.  Several high-performance cameras provide up to eight clear views which cover considerably more than 360° of the complete volume of each individual bottle.  The empty containers are purposefully rotated for this and optimally aligned at each individual detection station using precise servo technology.  At the same time a homogeneous illumination ensures that the detection pictures are without shadows or reflections.  These are combined and analysed by the HEUFT reflexx² in real time.  The high-performance image processing system distinguishes between harmless container structures and actual faults reliably in the course of this and implements a specific teach in.

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 and the health of the consumer.  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.  As with all the detection modules of the completely redesigned HEUFT InLine II IS the units for detecting residual liquid are fully integrated, safely enclosed and adjustable by motor.  This also applies to the HEUFT fluid which had to be positioned outside the inspector on the conveyor previously.  The compact module for detecting residual lye now demonstrates its impressive precision directly in the device due to the new construction of the empty bottle inspector.

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 changes

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

The precise servo technology not only carries out a specific rotation and exact fine adjustment of the bottles for a continuous complete inspection on the cleverly driven conveyor.  It also adapts the height and width of the conveyor belt exactly to the changed bottle format during brand changes.  The same applies to the positioning of all the detections.  This is achieved completely automatically due to clearly reproducible brand adjustments.  As a result 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 II systems with their modular design can be expanded at any time.  There is a choice of double or quadruple sidewall inspections depending on the performance range and quality requirements.  A special scuffing detection is available for those filling into returnable bottles.  This can be combined with a reject rate control so that those which are less severely scuffed are only removed when the production situation happens to permit it.  Defects and contamination hidden behind applied colour labels are made visible by the ACL detection which can be integrated at any time.  The HEUFT InLine II IS also provides different options for a finish and thread inspection – from a colour ring inspection of the sealing surface to an ovality detection.  Further residual liquid detections can be connected to the conveyor in addition to those already integrated in the device for redundant protection.
