DeltaPac reliably detects objects in a gapless product flow


Up to now, it was generally necessary to separate packages in order to count or detect them with the aid of, for example, photoelectric sensors.

With the DeltaPac, such a separation, which often involved complex mechanisms in conveyor systems, is now a thing of the past.

This is made possible by SICK’s patented Delta-S-Technology. Two energy scales each with two receivers and four PinPoint2.0 LEDs combined with SICK’s specific SIRIC ASIC technology and integrated distance measurement.

The DeltaPac’s principle of operation makes use of edge contours of objects. The edges cause the reflective behaviour of the packaging surface to change in the gapless transition from one object to another.

This changed direction of reflectivity is used for the output of switching signals. Object contours with radii up to 20 mm are reliably identified. The DeltaPac’s high-precision evaluation characteristic ensures that smallest changes in angles are reliably detected. Thus, it is possible to reliably identify up to 200,000 packages per hour with conveyor speeds up to 3 m/s.

The fact that the DeltaPac is able to detect objects aligned in a push-push configuration offers new possibilities in the construction of packaging machines. Machine elements for packaging buffering and separation mechanisms are no longer needed.

This saves costs and improves the space utilisation of the machine. The product flow is stabilised because collisions due to falling packages are reduced. Machine downtime, incorrect loading when grouping items and loss of quality due to crashes are reliably prevented – with a positive effect on time, energy and availability utilisation of the packaging machine.

SICK has met the requirements of manufacturers of packaging machines in terms of pre-configured devices by enabling fast commissioning without making any settings or specific process optimisation by tailored configuration.

Mount, connect, detect – the user will not have to grapple with comprehensive operating instructions. The sensor version with IO-Link allows to configure the sensor according to the application conditions, e.g. for various packages.

Side-by-side conveyance, differentiation, gapless counting and detection are possible with the DeltaPac.
