HEUFT PRIME

Inspecting the fill level, checking the presence, position and tightness of closures, detecting unlabelled full containers and serial faults and consistently rejecting faulty products: this is easier than ever before with the HEUFT PRIME ! Because the compact full container check combines different detection technologies with a high degree of automation and the audiovisual HEUFT NaVi user guidance.

Fill level detection
Finding underfills and overfills reliably: the right technology for each application.
Too little, too much or exactly right: the HEUFT PRIME can be perfectly equipped with different detection modules for a precise fill level detection.
It checks the filling quantity of transparent food jars with infrared technology highly precisely. The high frequency measurement provides exact results for all types of non-metal containers. X-ray technology for determining the exact filling quantity is used in the case of opaque packaging material such as cans of food.

Closure detection
Checking the tightness: special procedures for different closures.
Missing, incorrectly positioned and leaking: the HEUFT PRIME identifies closure faults such as these reliably. Different procedures are used for this: it checks the presence and position with special sensor and optical technologies. Therefore missing closures or closure elements which are too high are noticed immediately. The same applies to deviating closure curvatures which draw conclusions about the internal pressure and consequently the tightness of the containers.

Label check
Paying attention to the labels: specific examination of the presence.
Collar, body, neck or wrap-around label: there must not be any missing! The HEUFT PRIME checks whether this is really the case by means of special sensors which make use of the different reflection characteristics of the container surface and the label. Therefore it is immediately clear when one or several of them are missing. The sensors can be directly integrated in the labeller. A presence check is also possible whilst the containers are being transported on the conveyor as an alternative.

Serial fault detection
Noticing the repeated occurrence of defects in good time: locator for safeguarding productivity.
Specific, in good time and sustainable: the HEUFT PRIME prevents faults from becoming serial faults and impairing the productivity of the complete filling and packaging line. For example an integrated locator function records when a particular filler valve regularly underfills in good time.
A switch-off pulse is emitted when the number of faulty fillings exceeds a certain, individually adjustable threshold value. Therefore malfunctions can be rectified before they can threaten the safety and quality of complete batches and cause rejection rates which are too high. The HEUFT PRIME also notices recurring closure and labelling faults in good time and prevents these from going into production and thwarting the efficiency and productivity of the whole line by means of a stop signal.

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: adapting the detection units.
Fast, automatic and simple: the HEUFT PRIME carries out brand and program changes fully automatically. The height of the detection modules on the device adapts to the changed container format automatically. This protects against incorrect settings during brand changes due to operating errors, frees up human resources, saves time and money and minimises the risk of efficiency and productivity losses due to lengthy changeover times.

Optional additional functions
Detecting even more: extensions to the range of functions.
Modular, multifunctional and retrofittable: the functionality of the compact HEUFT PRIME can be optionally developed and extended. Therefore it can be equipped with up to two
in-house developed colour sensor cameras in which both the adaptive LED lighting and the real-time image processing are directly integrated. For example this makes a top-down and a lateral inspection of the closures possible in order to check, among other things, lid logos, colour and brand affiliation as well as finding defects. Or a detailed label inspection that is the detection and verification of product markings such as best before dates, barcodes and data matrix codes.
A special procedure can be incorporated for hot filled food products which takes into account and compensates for the effects of different product temperatures on the product volume during the fill level detection. A quantifying module which can be easily integrated converts the results of the individual fill level measurements automatically into the actual fill value and calculates the average value of the complete fill volume. Other additional detections check the container contour, find lost fill tubes, identify or check the presence of freshly applied laser coding on plastic packaging using a thermo sensor. A machine connection makes it possible not only to integrate detection units for checking fill levels, labels or closures directly in the filler, closer or labeller but also to identify downtimes of such master machines in good time. The HEUFT PRIME also controls automatic sampling on request.
