Covering everything: continuous empty bottle inspection.
An all-around inspection of glass and plastic containes before filling – The HEUFT InLine solve this task using a minimum amount of space whilst providing maximum inspection quality. Glass faults, foreign objects and dirt are detected by the compact empty bottle inspector particularly precisely. The HEUFT InLine covers the whole container volume completely with its base, finish and 360° sidewall inspection.
Optical base inspection
Covering everything:continuous complete inspection of the total container base.
Film, cigarette ends and insects: the system carries out an optical complete inspection of the container base 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. 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: specific rotation for full coverage.
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. Therefore the bottles are each specifically rotated between two photographs taken with specially positioned high-performance cameras.
The HEUFT reflexx image processing system combines the photographs without reflections or shadows into extremely clear detection pictures which cover the complete bottle volume by more than 360°. Therefore sidewall faults can no longer be overlooked.
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.
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 un-inspected. 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.
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.
