Only allowing in what is allowed in
HEUFT ensures a correct supply. With compact, new detection units which help to ensure that only empties of the correct brand, safe and easy to process flow into your filling line.
Too small, too large, too thick, too thin or too tightly closed: these are real exclusion criteria for bottles which should be filled safely without slowing down the efficiency and productivity of entire lines in the process. An automatic protective mechanism is required, purely for machine protection reasons, which prevents the supply of non-brand, misshapen or other not safe to process primary packaging materials for beverages at least wherever containers of different formats are transported.
Otherwise there is a risk of obstructions, machine damage and production standstills: for example containers which are too high get stuck in the empty bottle inspector and those which are too wide could get caught up in the integrated belt drive for the servo-controlled fine container alignment. The same applies to bottles which have toppled over and cannot be inspected or filled. And the detailed optical finish and thread inspection which is available with the HEUFT InLine II systems obviously only works when there are no lids on them. Heavily soiled or damaged empties should also be detected at an early stage and removed.
Automatic bottle shape detection
The first infeed check system for returnable PET bottles based on the highly automated HEUFT SPECTRUM II platform achieves this before unusable containers reach the washing machine where they can cause interference or a reduction in the cleaning effect. In addition there is now also a space-saving module for the new generation of HEUFT empty bottle inspectors for checking the infeed. It is equipped with photocells as standard for a specific bottle shape detection in order to identify incorrect empty containers which do not match the current production program. High performance cameras can be added as an option to achieve an even clearer distinction between good and faulty bottles. The inductive detection which can be additionally integrated if required identifies containers with metal closures. Also possible: a motorised vertical adjustment of all the detections for uncomplicated automatic brand changes.
Bottles on the infeed conveyor which cannot be safely transported and inspected are therefore identified and rendered harmless by the new checking module before they reach the respective HEUFT InLine II system for a comprehensive empty bottle inspection. A conveyor stop signal is generated by default in order to be able to remove them from the production flow safely. Alternatively it is advisable to use a rejection system such as the HEUFT DELTA-K folding rejector which removes faulty empties from the production flow upright in particular for higher line outputs which do not permit interruptions.
A homogeneous and flawless supply
The new upstream infeed check, as a compact module connected to empty bottle inspectors based on the HEUFT SPECTRUM II, does not require its own terminal: it can simply be safely controlled directly at the device via the integrated HEUFT NaVi user guidance with extensive audiovisual assistance. On the other hand the above-mentioned stand-alone system for carefully checking the infeed of refillable PET containers into the bottle washer has its own highly automated control unit with a self-explanatory machine human interface. Nevertheless it can be integrated directly at the conveyor in a space-saving and flexible manner.
Whether in front of or behind the washing machine, whether for empty bottles made of plastic or glass: both solutions ensure that only those containers which meet the necessary criteria are transferred to the filling line. A correct infeed is ensured.
