Fill level detection and laning of aerosol containers

Tuesday 30. November 2010 - Checking the fill level of aerosol containers with X-ray technology and dividing up the container flow: this is also possible in potentially explosive areas with the HEUFT VX ATEX which will be demonstrated on the Emballage Stand E 002 in Hall 5a.

The HEUFT VX ATEX bears the marking Ex II 3G EEX IIB T4 and can therefore be operated in the Ex area of aerosol lines. The strict separation of control unit and X-ray detection makes this possible. Whereas the former is outside the hazard zone the latter can operate without any problems and safely in an ATEX Group II, Category 3G risk area. The fill level detection is an efficiency increasing alternative to conventional weighing systems. Because it reduces the required gap between the spray cans on the conveyor. This makes the increase in efficiency and throughput during the inline determination of the filling quantities of aerosol containers, which the market demands, possible. The device can be equipped with up to two X-ray measuring bridges depending on the size and format so that underfills as well as overfills can be precisely identified. The average filling quantity of complete batches can also be checked with the integrated quantifying system.
The HEUFT VX ATEX also increases efficiency as a laning system. It divides up the container flow and therefore avoids jams in the conveyor sections which are running slowly. The ratio with which the system allocates the aerosol containers to the different conveyors is freely selectable. Jam detectors ensure that the lanes are evenly used to capacity. Full sections are automatically identified and excluded from the laning system. This prevents efficiency losses or even production stops in the case of lines which are running at their capacity limit. In addition an upright rejection of the spray cans is possible with the HEUFT DELTA-FW multi-segment rejector as an alternative to the laning system.
